| Organization, Consolidation and Presentation Of Financial Statements |
Baidu, Inc. (“Baidu” or the “Company”) was incorporated under the laws of the Cayman Islands on January 18, 2000. The Company, its subsidiaries, VIEs and subsidiaries of the VIEs are hereinafter collectively referred to as the “Group.” As of December 31, 2018, the Company has subsidiaries incorporated in countries and jurisdictions including the People’s Republic of China (“PRC”), Hong Kong, Japan, Cayman Islands and British Virgin Islands (“BVI”). As of December 31, 2018, the Company also effectively controls a number of variable interest entities (“VIEs”) through the Primary Beneficiaries, as defined below. The VIEs include:
The Group offers online marketing services, operates AI-powered new business initiatives, and operates an online video platform offering membership services of its content library and online marketing services. The Group’s principal geographic market is in the PRC. The Company does not conduct any substantive operations of its own, but conducts its primary business operations through its subsidiaries and VIEs in the PRC. PRC laws and regulations prohibit or restrict foreign ownership of internet content, advertising, audio and video services, and mobile application distribution businesses. To comply with these foreign ownership restrictions, the Group operates its websites and primarily provides services subject to such restriction in the PRC through the VIEs, the PRC legal entities that were established or whose equity shares were held by the individuals authorized by the Group. The paid-in capital of the VIEs was mainly funded by the Company or its subsidiaries through loans extended to the authorized individuals who were the shareholders of the VIEs. The Company or its subsidiaries have entered into proxy agreements or powers of attorney and exclusive equity purchase option agreement with the VIEs and nominee shareholders of the VIEs through the Company or its subsidiaries (“Primary Beneficiaries”), which give the Primary Beneficiaries the power to direct the activities that most significantly affect the economic performance of the VIEs and to acquire the equity interests in the VIEs when permitted by the PRC laws, respectively. Certain exclusive agreements have been entered into with the VIEs through the Primary Beneficiaries or their subsidiaries in the PRC, which obligate the Primary Beneficiaries to absorb losses or receive economic benefits of the VIEs’ that could potentially be significant to the VIEs or entitle the Primary Beneficiaries to receive economic benefits from the VIEs that could potentially be significant to the VIEs. In addition, the Company or its subsidiaries have entered into certain agreements with the shareholders of the VIEs through the Primary Beneficiaries or their subsidiaries, including loan agreements for the paid-in capital of the VIEs and equity pledge agreements for the equity interests in the VIEs held by the shareholders of the VIEs. Despite the lack of legal majority ownership, there exists a parent-subsidiary relationship between the Primary Beneficiaries and the VIEs through the aforementioned agreements with the shareholders of the VIEs. The shareholders of the VIEs effectively assigned all of their voting rights underlying their equity interest in the VIEs to the Primary Beneficiaries. In addition, through the other exclusive agreements, which consist of operating agreements, technology consulting and services agreements and license agreements, the Primary Beneficiaries, by themselves or their subsidiaries in the PRC, demonstrate their ability and intention to continue to exercise the ability to absorb losses or receive economic benefits that could potentially be significant to the VIEs. The VIEs are subject to operating risks, which determine the variability of the Company’s interest in those entities. Based on these contractual arrangements, the Company consolidates the VIEs as required by Accounting Standards Codification (“ASC”) Topic 810, Consolidation. Unrecognized revenue-producing assets held by the VIEs include certain internet content provisions and other licenses, domain names and trademarks. The internet content provisions and other licenses, which are held by the VIEs that provide the relevant services, are required under relevant PRC laws, rules and regulations for the operation of Internet businesses in the PRC, and therefore are integral to the Company’s operations. The principal terms of the agreements entered into amongst the VIEs, their respective shareholders and the Primary Beneficiaries before the amendments made in March 2018 are further described below. Loan Agreements Pursuant to loan agreements amongst the shareholders of Baidu Netcom and Baidu Online Network Technology (Beijing) Co., Ltd. (“Baidu Online”), one of the Company’s subsidiaries, Baidu Online provided interest-free loans in an aggregate amount of RMB6.4 billion (US$934 million) to the shareholders of Baidu Netcom solely for the latter to fund the capitalization of Baidu Netcom. The loans can be repaid only with the proceeds from the sale of the shareholders’ equity interest in Baidu Netcom to Baidu Online or its designated person. The terms of the loan agreements will expire on May 6, 2028 at the earliest and can be extended with the written consent of both parties before its expiration. Each of the loan agreements amongst Baidu Online or other subsidiaries and the respective shareholders of Beijing Perusal or other VIEs contains substantially the same terms as those described above, except that the amount of the loans and the contract expiry date varies. The amount of loans extended to the respective shareholders of Beijing Perusal is RMB3.2 billion (US$465 million). The term of the loan agreements will expire on March 30, 2028 and June 27, 2028, and can be extended with the written consent of both parties before its expiration. Exclusive Equity Purchase and Transfer Option Agreement Pursuant to the exclusive equity purchase and transfer option agreement amongst the shareholders of Baidu Netcom, Baidu Netcom and Baidu Online, the shareholders of Baidu Netcom irrevocably granted Baidu Online or its designated person(s) an exclusive option to purchase, to the extent permitted under PRC law, all or part of the equity interests in Baidu Netcom for the cost of the initial contributions to the registered capital or the minimum amount of consideration permitted by applicable PRC law. The shareholders should remit to Baidu Online any amount that is paid by Baidu Online or its designated person(s) in connection with the purchased equity interest. Baidu Online or its designated person(s) have sole discretion to decide when to exercise the option, whether in part or in full. Any and all dividends and other capital distributions made by Baidu Netcom to its shareholders should be repaid to Baidu Online in full amount. Baidu Online would provide unlimited financial support to Baidu Netcom if, in the normal operation of business, Baidu Netcom would become in need of any form of reasonable financial support. If Baidu Netcom were to incur any loss and as a result cannot repay any loans from Baidu Online, Baidu Online should unconditionally forgive any such loans to Baidu Netcom given that Baidu Netcom provides sufficient proof for its loss and incapacity to repay. The agreement will terminate when the shareholders of Baidu Netcom have transferred all their equity interests in Baidu Netcom to Baidu Online or its designated person(s) or upon expiration of the term of business of Baidu Online or Baidu Netcom. Each of the exclusive equity purchase and transfer option agreements amongst Baidu Online or other subsidiaries, Beijing Perusal and their shareholders, or other VIEs and their shareholders contains substantially the same terms as those described above. Each of the agreements will terminate upon the transfer of all the equity interests held by the shareholders of Beijing Perusal or other VIEs, as the case may be, to Baidu Online or its designated person(s) or upon expiration of the term of business of Baidu Online, Beijing Perusal or other VIEs. Proxy Agreement/Power of Attorney Pursuant to the proxy agreement between Baidu Online and the shareholders of Baidu Netcom, the shareholders of Baidu Netcom agreed to entrust all the rights to exercise their voting power and any other rights as shareholders of Baidu Netcom to the person(s) designated by Baidu Online. The shareholders of Baidu Netcom have each executed an irrevocable power of attorney to appoint the person(s) designated by Baidu Online as their attorney-in-fact to vote on their behalf on all matters requiring shareholder approval. The proxy agreement would be in effect for an unlimited term unless terminated in writing by Baidu Online. The power of attorney would be in effect for as long as the shareholders of Baidu Netcom hold any equity interests in Baidu Netcom. Each of the proxy agreements or shareholder voting rights trust agreements amongst Baidu Online or other subsidiaries and the shareholders of Beijing Perusal and other VIEs contains substantially the same terms as those described above. Each of the proxy agreements will be in effect for an unlimited term unless terminated in writing by Baidu Online. Each of the powers of attorney will be in effect for as long as the shareholder of Beijing Perusal or other VIEs holds any equity interests in Beijing Perusal or other VIEs, as the case may be. Operating Agreement Pursuant to the operating agreement amongst Baidu Online, Baidu Netcom and the shareholders of Baidu Netcom, Baidu Online provides guidance and instructions on Baidu Netcom’s daily operations and financial affairs. Baidu Online has the power to appoint senior executives of Baidu Netcom. The shareholders of Baidu Netcom must appoint the candidates recommended by Baidu Online as their representatives on Baidu Netcom’s board of directors. In addition, Baidu Online agrees to guarantee Baidu Netcom’s performance under any agreements or arrangements relating to Baidu Netcom’s business arrangements with any third party. In return, Baidu Netcom agrees that without the prior consent of Baidu Online, Baidu Netcom will not engage in any transactions that could materially affect the assets, liabilities, rights or operations of Baidu Netcom, including, without limitation, incurrence or assumption of any indebtedness, sale or purchase of any assets or rights, incurrence of any encumbrance on any of its assets or intellectual property rights in favor of a third party or transfer of any agreements relating to its business operation to any third party. The agreement will be in effect for an unlimited term, until the term of business of Baidu Online or Baidu Netcom expires and extension is denied by the relevant approval authorities. Each of the operating agreements amongst Baidu Online or other subsidiaries, Beijing Perusal and their shareholders or other VIEs and their shareholders contains substantially the same terms as those described above. Each of the agreements will be in effect for an unlimited term, until the term of business of Baidu Online, Beijing Perusal or other VIEs expires and extension is denied by the relevant approval authorities. Exclusive Technology Consulting and Services Agreement Pursuant to the exclusive technology consulting and services agreement between Baidu Online and Baidu Netcom, Baidu Online has the exclusive right to provide technology consulting and services related to, among other things, the maintenance of servers, software development, design of advertisements, and e-commerce technical services to Baidu Netcom. Baidu Online owns the intellectual property rights resulting from the performance of this agreement. Baidu Netcom agrees to pay service fees to Baidu Online and Baidu Online has the right to adjust the service fees at its sole discretion without the consent of Baidu Netcom. The agreement will be in effect for an unlimited term, until the term of business of one party expires and extension is denied by the relevant approval authorities.
Each of the exclusive technology consulting and services agreements between Baidu Online or other subsidiaries and Beijing Perusal or other VIEs contains substantially the same terms as those described above, except the basis of determining the service fees may differ. License Agreements Baidu Online and Baidu Netcom entered into a software license agreement and a web layout copyright license agreement (collectively, the “License Agreements”). Pursuant to the License Agreements between Baidu Online and Baidu Netcom, Baidu Online has granted to Baidu Netcom the right to use (including but not limited to) a software license and a web layout copyright license. Baidu Netcom may only use the licenses in its own business operations. Baidu Online has the right to adjust the service fees at its sole discretion. The software license agreement and web layout copyright license agreement were renewed since their original expiration and would be in effect for an unlimited term, until the term of business of one party expires and extension is denied by the relevant approval authorities. Baidu Online entered into web layout copyright license agreements with Beijing Perusal. Each of the license agreements between the Baidu Online and Beijing Perusal or other VIEs contains substantially the same terms as those described above. Each of the web layout copyright license agreements was renewed in 2013 and would be in effect for an unlimited term, until the term of business of one party expires and extension is denied by the relevant approval authorities. Equity Pledge Agreement Pursuant to the equity pledge agreement between Baidu Online and the shareholders of Baidu Netcom, the shareholders of Baidu Netcom pledged all of their equity interests in Baidu Netcom to Baidu Online to guarantee their obligations under the loan agreement and Baidu Netcom’s performance of its obligations under the exclusive technology consulting and services agreement. If Baidu Netcom or its shareholders breach their respective contractual obligations, Baidu Online, as the pledgee, will be entitled to certain rights, including the right to sell the pledged equity interests. The shareholders of Baidu Netcom agreed not to dispose of the pledged equity interests or take any actions that would prejudice Baidu Online’s interest. The equity pledge agreement will expire two years after expiration of the term or the fulfillment by Baidu Netcom and its shareholders of their respective obligations under the exclusive technology consulting and services agreement and the loan agreement. Each of the equity pledge agreements amongst Baidu Online or other subsidiaries and the shareholders of Beijing Perusal or other VIEs contains substantially the same terms, including its term to expiration, as those described above. Through the design of the aforementioned agreements, the shareholders of the VIEs effectively assigned their full voting rights to Baidu Online, which gives Baidu Online the power to direct the activities that most significantly impact the VIEs’ economic performance. Baidu Online obtains the ability to approve decisions made by the VIEs and the ability to acquire the equity interests in the VIEs when permitted by PRC law. Baidu Online is obligated to absorb losses or receive economic benefits of the VIEs that could potentially be significant to the VIEs through providing unlimited financial support to the VIEs or is entitled to receive economic benefits from the VIEs that could potentially be significant to the VIEs through the exclusive technology consulting and service fees. As a result of these contractual agreements, Baidu Online is determined to be the primary beneficiary of the VIEs. Despite the lack of technical majority ownership, there exists a parent-subsidiary relationship between the Company and the VIEs through these contractual agreements, and the Company consolidates the VIEs through Baidu Online. There are similar agreements entered into amongst iQIYI, Inc. (“iQIYI”), iQIYI subsidiaries, iQIYI VIEs, and the respective shareholders, which resulted in a parent-subsidiary relationship between iQIYI and iQIYI VIEs.
In March 2018, the contractual agreements for certain VIEs, including Baidu Netcom and Beijing Perusal, were amended to include the following terms:
The Company has (i) an exclusive option to purchase, when and to the extent permitted under PRC laws, all or part of the equity interests in the VIE or all or part of the assets held by the VIE, (ii) an exclusive right to cause the nominee shareholders to transfer their equity interest in the VIE to the Company or any designated person and (iii) an obligation to provide unlimited financial support to the VIEs when the VIEs become in need of any form of reasonable financial support in the normal operation of business. If the VIEs were to incur any loss and as a result cannot repay any loans from the Company, the Company will unconditionally forgive any such loans to the VIEs upon provision by the VIEs of sufficient proof for its loss and incapacity to repay.
The appointment of any individuals to exercise the powers and rights assigned pursuant to the Proxy Agreement requires the approval of the Company. All the activities in relation to such powers and rights assigned are directed and approved by the Company. The shareholders of the VIEs agreed to entrust all the rights to exercise their voting power and any other rights as shareholders of the VIEs to the person(s) designated by the Company. The shareholders of the VIEs have each executed an irrevocable power of attorney to appoint the person(s) designated by the Company as their attorney-in-fact to vote on their behalf on all matters requiring shareholder approval. As a result, the power and the rights pursuant to the Proxy Agreements have since been effectively reassigned from Baidu Online to the Company which has the power to direct the activities of the VIEs that most significantly impact the VIEs’ economic performance. The Company is also obligated to absorb the expected losses or receive economic benefits of the VIE through the financial support as described above. Therefore, the Company has replaced Baidu Online as the Primary Beneficiary of Baidu Netcom and Beijing Perusal since March 2018. As the VIEs were subject to indirect control by the Company through its subsidiaries immediately before and direct control immediately after the contractual agreements were amended, the change of the primary beneficiary of the VIEs was accounted for as a common control transaction based on the carrying amount of the net assets transferred. In the opinion of the Company’s legal counsel, (i) the ownership structure relating to the VIEs of the Company is in compliance with existing PRC laws and regulations; (ii) the contractual arrangements with the VIEs and their shareholders are valid, binding and enforceable, and will not result in any violation of PRC laws or regulations currently in effect; and (iii) the performance of the VIEs and their shareholders is in compliance with the articles of association and business licenses of the VIEs. However, uncertainties in the PRC legal system could cause the Company’s current ownership structure to be found in violation of any existing and/or future PRC laws or regulations and could limit the Company’s ability, through the Primary Beneficiaries, to enforce its rights under these contractual arrangements. Furthermore, shareholders of the VIEs may have interests that are different with those of the Company, which could potentially increase the risk that they would seek to act in contrary to the terms of the aforementioned agreements. In addition, if the current structure or any of the contractual arrangements were found to be in violation of any existing or future PRC laws, the Company may be subject to penalties, which may include but not be limited to, the cancellation or revocation of the Company’s business and operating licenses, being required to restructure the Company’s operations or discontinue the Company’s operating activities. The imposition of any of these or other penalties may result in a material and adverse effect on the Company’s ability to conduct its operations. In such case, the Company may not be able to operate or control the VIEs, which may result in deconsolidation of the VIEs. The following tables set forth the financial statement balances and amounts of the VIEs and their subsidiaries were included in the consolidated financial statements after the elimination of intercompany balances and transactions among VIEs and their subsidiaries within the Group:
As of December 31, 2018, there was no pledge or collateralization of the VIEs’ assets that can only be used to settle obligations of the VIEs, other than aforementioned in the equity pledge agreements and collateralization of a VIE’s office building as described in Note 10. The amount of the net assets of the VIEs was RMB9.0 billion (US$1.3 billion) as of December 31, 2018. The creditors of the VIEs’ third-party liabilities did not have recourse to the general credit of the Company in normal course of business. The Company did not provide or intend to provide financial or other supports not previously contractually required to the VIEs during the years presented. Basis of Presentation The consolidated financial statements are prepared in accordance with United States generally accepted accounting principles (“U.S. GAAP”). Principles of Consolidation The consolidated financial statements include the financial statements of the Company, its subsidiaries, VIEs and subsidiaries of the VIEs. All inter-company transactions and balances between the Company, its subsidiaries, VIEs and subsidiaries of the VIEs are eliminated upon consolidation. The Company included the results of operations of acquired businesses from the respective dates of acquisition. Use of Estimates The preparation of the financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the period. Management evaluates estimates, including those related to the standalone selling prices of performance obligations of revenue contracts, accounts receivable and contract assets allowances, credit loss allowance for micro loan receivables, fair values of certain debt and equity investments, amortization and impairment of licensed copyrights and produced content, ultimate revenue of produced content, fair value of nonmonetary content exchanges, impairment of long-lived assets, long-term investments and goodwill, the purchase price allocation and fair value of noncontrolling interests with respect to business combinations, deferred tax valuation allowance, and redeemable noncontrolling interests, among others. Management bases the estimates on historical experience and on various other assumptions that are believed to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities. Actual results could differ from these estimates.
Currency Translation for Financial Statements Presentation Translations of amounts from RMB into US$ for the convenience of the reader have been calculated at the exchange rate of RMB6.8755 per US$1.00 on December 31, 2018, the last business day in fiscal year 2018, as published on the website of the United States Federal Reserve Board. No representation is made that the RMB amounts could have been, or could be, converted into U.S. dollars at such rate. |

| Summary of Significant Accounting Policies |
Foreign Currency The Company’s functional currency is the US$. The Company’s subsidiaries, VIEs and subsidiaries of the VIEs determine their functional currencies based on the criteria of ASC Topic 830, Foreign Currency Matters. The Company uses the RMB as its reporting currency. The Company uses the exchange rate as of the balance sheet date to translate its assets and liabilities and the average daily exchange rate for each month to translate its income and expense items to reporting currency. Any translation gains (losses) are recorded in other comprehensive income (loss). Transactions denominated in foreign currencies are measured and recorded into the functional currency at the exchange rates prevailing on the transaction dates. Assets and liabilities denominated in foreign currencies other than functional currency are remeasured into the functional currency at the exchange rates prevailing at the balance sheet date. Exchange gains and losses are included in earnings as a component of “Other income, net.” Segment Reporting As of December 31, 2017 and 2018, the Company had two reportable segments, Baidu Core and iQIYI. Baidu Core mainly provides search-based, feed-based, and other online marketing services, as well as new artificial intelligence business. Search Services and Transaction Services were combined into Baidu Core beginning April 2017, to reflect the Company’s strategic and operational change to de-emphasize its transaction services business and shift more resources to support its online marketing and other services. iQIYI is an online entertainment service provider that, offers original, professionally produced and partner-generated content on its platform. In early April 2018, iQIYI completed its initial public offering (“IPO”) on the Nasdaq Global Market. The Company’s chief executive officer, who has been identified as the chief operating decision marker (“CODM”), reviews the operating results of Baidu Core and iQIYI, to allocate resources and assess the Company’s performance. Accordingly, the financial statements include segment information which reflects the current composition of the reportable segments in accordance with ASC Topic 280, Segment Reporting. Business Combinations The Company accounts for its business combinations using the purchase method of accounting in accordance with ASC Topic 805, Business Combinations. The purchase method of accounting requires that the consideration transferred to be allocated to the assets, including separately identifiable assets and liabilities the Company acquired, based on their estimated fair values. The consideration transferred in an acquisition is measured as the aggregate of the fair values at the date of exchange of the assets given, liabilities incurred, and equity instruments issued as well as the contingent considerations as of the acquisition date. The costs directly attributable to the acquisition are expensed as incurred. Identifiable assets, liabilities and contingent liabilities acquired or assumed are measured separately at their fair value as of the acquisition date, irrespective of the extent of any noncontrolling interests. The excess of (i) the total of cost of acquisition, fair value of the noncontrolling interests and acquisition date fair value of any previously held equity interest in the acquiree over (ii) the fair value of the identifiable net assets of the acquiree, is recorded as goodwill. If the cost of acquisition is less than the fair value of the net assets of the subsidiary acquired, the difference is recognized directly in earnings. In a business combination achieved in stages, the Company remeasures its previously held equity interest in the acquiree immediately before obtaining control at its acquisition-date fair value and the re-measurement gain or loss, if any, is recognized in earnings. The determination and allocation of fair values to the identifiable assets acquired, liabilities assumed and noncontrolling interests is based on various assumptions and valuation methodologies requiring considerable judgment from management. The most significant variables in these valuations are discount rates, terminal values, the number of years on which to base the cash flow projections, as well as the assumptions and estimates used to determine the cash inflows and outflows. The Company determines discount rates to be used based on the risk inherent in the related activity’s current business model and industry comparisons. Terminal values are based on the expected life of assets, and forecasted cash flows over that period. Cash, Cash Equivalents and Restricted Cash Cash and cash equivalents Cash and cash equivalents primarily consist of cash, money market funds, investments in interest bearing demand deposit accounts, time deposits and highly liquid investments with original maturities of three months or less from the date of purchase and are stated at cost which approximates their fair value. Restricted cash Restricted cash mainly consists of the cash reserved in escrow accounts at certain banks as online payment service deposits and cash pledged for bank loan facility. In November 2016, the FASB issued Accounting Standards Update No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash, which requires companies to include amounts generally described as restricted cash and restricted cash equivalents in cash and cash equivalents when reconciling beginning-of-period and end-of-period total amounts presented in the statement of cash flows. The Company adopted the new standard effective January 1, 2018, using the retrospective transition method. All restricted cash was presented on the face of the consolidated balance sheet as “Restricted cash.” Accounts Receivable, net of allowance Accounts receivable are recognized and carried at the original invoiced amount less an allowance for any potential uncollectible amounts. An estimate for doubtful debts is made when collection of the full amount is no longer probable. Receivable balances are written off when they are deemed uncollectible. The Company generally does not require collateral from its customers. The Company maintains allowances for doubtful accounts for estimated losses resulting from the failure of customers to make payments on time. The Company reviews the accounts receivable on a periodic basis and makes general and specific allowances when there is doubt as to the collectability of individual balances. In evaluating the collectability of individual receivable balances, the Company considers many factors, including the age of the balance, the customer’s payment history, its current credit-worthiness and current economic trends.
Receivables from Online Payment Agencies, net of allowance Receivables from online payment agencies are funds due from the third-party online payment service providers for clearing transactions. Funds were paid or deposited by customers or users through these online payment agencies for services provided by the Company. The Company carefully considers and monitors the credit worthiness of the third-party payment service providers used. An allowance for doubtful accounts is recorded in the period in which a loss is determined to be probable. Receivable balances are written off when they are deemed uncollectible. The balances are included in “Other current assets, net” on the consolidated balance sheets. As of December 31, 2017 and 2018, no allowance for doubtful accounts was provided for the receivables from online payment agencies. Loan and Interest Receivables, net of allowance Loan and interest receivables consist primarily of micro loans to individual borrowers. Such amounts are recorded at the principal net of allowance for credit losses relating to micro loans, and include accrued interest receivable as of the balance sheet date. The loan periods granted by the Company to the borrowers related to the micro loans generally range from one month to thirty-six months. The cash flows related to micro loans are included within the cash flows from investing activities category in the consolidated statement of cash flows. Allowance for credit losses relating to micro loans represent the Company’s best estimate of the losses inherent in the outstanding portfolio of loans. Judgment is required to determine the allowance amounts and whether such amounts are adequate to cover potential credit losses, and periodic reviews are performed to ensure such amounts continue to reflect the best estimate of the losses inherent in the outstanding portfolio of debts. The Company bases the allowance for loan and interest receivables credit losses primarily on historical loss experience using a roll rate-based model applied to the loan and interest receivables portfolios. The Company considers many factors, including but not limited to, the age of the amounts due, the payment history, the month of origination, the purpose of the loans, creditworthiness, financial conditions of the borrower, terms of the loans, regulatory environment, and the general economic conditions. In August 2018, the Company completed the divestiture of its financial services business, and related loan and interest receivable balances were derecognized from the consolidated balance sheet upon disposal (Note 4). Investments Short-term investments All highly liquid investments with original maturities of greater than three months, but less than twelve months, are classified as short-term investments. Investments that are expected to be realized in cash during the next twelve months are also included in short-term investments. The Company accounts for short-term debt investments in accordance with ASC Topic 320, Investments—Debt Securities (“ASC 320”). The Company classifies the short-term investments in debt as “held-to-maturity,” “trading” or “available-for-sale,” whose classification determines the respective accounting methods stipulated by ASC 320. Dividend and interest income, including amortization of the premium and discount arising at acquisition, for all categories of investments in securities are included in earnings. Any realized gains or losses on the sale of the short-term investments are determined on a specific identification method, and such gains and losses are reflected in earnings during the period in which gains or losses are realized. Securities that the Company has positive intent and ability to hold to maturity are classified as held-to-maturity securities and stated at amortized cost. For individual securities classified as held-to-maturity securities, the Company evaluates whether a decline in fair value below the amortized cost basis is other-than-temporary in accordance with ASC 320. Other-than-temporary impairment loss is recognized in earnings equal to the entire excess of the debt security’s amortized cost basis over its fair value at the balance sheet date of the reporting period for which the assessment is made. Securities that are bought and held principally for the purpose of selling them in the near term are classified as trading securities, in accordance with ASC 320. Unrealized holding gains and losses for trading securities are included in earnings. Debt investments not classified as trading or as held-to-maturity are classified as available-for-sale debt securities, which are reported at fair value, with unrealized gains and losses recorded in “Accumulated other comprehensive income.” An impairment loss on the available-for-sale debt securities is recognized in the consolidated statements of comprehensive income when the decline in value is determined to be other-than-temporary. Other invested securities Other invested securities represent investments purchased by the Company for its financial services business and are resold to third-party investors. These transactions do not meet the requirements of asset derecognition in accordance with ASC Topic 860, Transfers and Servicing (“ASC 860”). The Company records the proceeds related to these transactions as secured borrowings included in “Amounts due to the third-party investors” on the consolidated balance sheets, and assets pledged are included in “Other invested securities” on the consolidated balance sheets. Other invested securities are issued by financial institutions and have a variable rate of return that is indexed to the performance of underlying assets. The Company initially records these investments at cost, which approximates its fair value at inception and subsequently records these investments at fair value. Changes in the fair value are reflected in earnings. The cash flows related to purchases and maturities of other invested securities are classified as cash flows from investing activities, while proceeds and payments related to the sale and purchase of financial products are classified as cash flows from financing activities in the consolidated statements of cash flows. All other invested securities balances were derecognized from the consolidated balance sheet upon the disposal of the financial services business (Note 4). Long-term investments The Company’s long-term investments consist of equity investments with and equity investments without readily determinable fair value, equity method investments, available-for-sale debt investments and other investments accounted for at fair value. Prior to adopting ASC Topic 321, Investments—Equity Securities (“ASC 321”) on January 1, 2018, the Company carries at cost its investments in investees that do not have readily determinable fair value and over which the Company does not have significant influence, in accordance with ASC Subtopic 325-20, Investments-Other: Cost Method Investments. The Company only adjusts the carrying value of such investments for other-than-temporary decline in fair value and for distribution of earnings that exceed the Company’s share of earnings since its investment. Management regularly evaluates the impairment of the cost method investments based on the performance and financial position of the investee as well as other evidence of market value. Such evaluation includes, but is not limited to, reviewing the investee’s cash position, recent financing, projected and historical financial performance, cash flow forecasts and financing needs. An impairment loss is recognized in earnings equal to the excess of the investment’s cost over its fair value at the balance sheet date of the reporting period for which the assessment is made. The fair value would then become the new cost basis of the investment. Subsequent to the Company’s adoption of ASC 321 on January 1, 2018, the cumulative effect of RMB1.9 billion (US$270 million) representing the unrealized gains and losses of available-for-sale equity securities before the adoption was recorded as an adjustment to the opening retained earnings. Pursuant to ASC 321, equity investments, except for those accounted for under the equity method, those that result in consolidation of the investee and certain other investments, are measured at fair value, and any changes in fair value are recognized in earnings. For equity securities without readily determinable fair value and do not qualify for the existing practical expedient in ASC Topic 820, Fair Value Measurements and Disclosures (“ASC 820”) to estimate fair value using the net asset value per share (or its equivalent) of the investment, the Company elected to use the measurement alternative to measure those investments at cost, less any impairment, plus or minus changes resulting from observable price changes in orderly transactions for identical or similar investments of the same issuer, if any. Equity securities with readily determinable fair value are measured at fair values, and any changes in fair value are recognized in earnings. Pursuant to ASC 321, for equity investments measured at fair value with changes in fair value recorded in earnings, the Company does not assess whether those securities are impaired. For those equity investments that the Company elects to use the measurement alternative, the Company makes a qualitative assessment of whether the investment is impaired at each reporting date. If a qualitative assessment indicates that the investment is impaired, the entity has to estimate the investment’s fair value in accordance with the principles of ASC 820. If the fair value is less than the investment’s carrying value, the entity has to recognize an impairment loss in net income equal to the difference between the carrying value and fair value. Available-for-sale debt investment is convertible debt instrument issued by a private company, which is measured at fair value, with unrealized gain or loss recorded in accumulated other comprehensive income. Investments in entities in which the Company can exercise significant influence but does not own a majority equity interest or control are accounted for using the equity method of accounting in accordance with ASC Topic 323,Investments-Equity Method and Joint Ventures (“ASC 323”). Under the equity method, the Company initially records its investment at cost and the difference between the cost of the equity investee and the fair value of the underlying equity in the net assets of the equity investee is recognized as equity method goodwill, which is included in the equity method investment on the consolidated balance sheets. The Company subsequently adjusts the carrying amount of its investment to recognize the Company’s proportionate share of each equity investee’s net income or loss into earnings. The Company will discontinue applying the equity method if an investment (plus additional financial support provided to the investee, if any) has been reduced to zero. When the Company has other investments in its equity-method investee and is not required to advance additional funds to that investee, the Company would continue to report its share of equity method losses in its statement of comprehensive income after its equity-method investment in ordinary shares has been reduced to zero, to the extent of and as an adjustment to the adjusted basis of the Company’s other investments in the investee. Such losses are first applied to those investments of a lower liquidation preference before being further applied to the investments of a higher liquidation preference. The Company adopted a one-quarter lag in reporting for its share of equity income (loss) in all of its investees. The Company evaluates the equity method investments for impairment whenever events or changes in circumstances indicate that the carrying amount of the investment might not be recoverable. Factors considered by the Company when determining whether an investment has been other-than-temporarily-impaired, includes, but not limited to, the length of the time and the extent to which the market value has been less than cost, the financial performance and near-term prospect of the investee, and the Company’s intent and ability to retain the investment until the recovery of its cost. An impairment loss on the equity method investments is recognized in earnings when the decline in value is determined to be other-than-temporary. In accordance with ASC 946-320 Financial Services—Investment Companies, Investments—Debt and Equity Securities, the Company accounts for long-term equity investments in unlisted companies held by consolidated investment companies at fair value. These investments were initially recorded at their transaction price net of transaction costs, if any. Fair value of these investments are re-measured periodically in accordance with ASC 820. Transfers of Financial Assets The Company accounts for the transfers of financial assets in accordance with ASC 860. Financial assets are derecognized from the Company’s consolidated balance sheets if the transfer qualifies as sales. If the conditions for sale required by ASC 860 are not met, the transfer is considered to be a secured borrowing included in “Amounts due to the third-party investors” on the consolidated balance sheets. The assets remain on the consolidated balance sheets as “Other invested securities” and the sale proceeds are recognized as the Company’s liability. All other invested securities and liability balances were derecognized from the consolidated balance sheet upon disposal of the financial services business (Note 4). Fair Value Measurements of Financial Instruments Financial instruments are in the form of cash and cash equivalents, restricted cash, short-term investments, other invested securities, accounts receivable, loan and interest receivables, amounts due from and due to related parties, other receivables, long-term investments, short-term loans, accounts payable and accrued liabilities, customer advances and deposits, derivative instruments, notes payable, convertible senior notes and long-term loans. The carrying values of the aforementioned financial instruments included in current assets and liabilities approximate their respective fair values because of their general short maturities. The carrying amounts of long-term loans approximate fair values as the related interest rates approximate rates currently offered by financial institutions for similar debt instruments of comparable maturities. Fixed Assets Fixed assets are stated at cost less accumulated depreciation. Depreciation is recorded on a straight-line basis over the shorter of the estimated useful lives of the assets or the term of the related lease, as follows:
Fixed assets have no estimated residual value except for the office building and its related facility, machinery and equipment, which have an estimated residual value of 4% of the cost.
Repair and maintenance costs are charged to expense as incurred, whereas the cost of renewals and betterments that extend the useful life of fixed assets are capitalized as additions to the related assets. Retirements, sales and disposals of assets are recorded by removing the cost and accumulated depreciation from the asset and accumulated depreciation accounts with any resulting gain or loss reflected in earnings. All direct and indirect costs that are related to the construction of fixed assets and incurred before the assets are ready for their intended use are capitalized as construction in progress. Construction in progress is transferred to specific fixed assets items and depreciation of these assets commences when they are ready for their intended use. Interest costs are capitalized if they are incurred during the acquisition, construction or production of a qualifying asset and such costs could have been avoided if expenditures for the assets have not been made. Capitalization of interest costs commences when the activities to prepare the asset are in progress and expenditures and borrowing costs are being incurred. Interest costs are capitalized until the assets are ready for their intended use. Interest costs capitalized for the years ended December 31, 2016, 2017 and 2018 were insignificant. Licensed Copyrights Licensed copyrights consist of professionally-produced content such as movies, television series, variety shows, sports and other video content acquired from external parties. The license fees are capitalized and, unless prepaid, a corresponding liability recorded when cost of the content is known, the content has been accepted by us in accordance with the conditions of the license agreement and the content is available for its first showing on our internet platform. Licensed copyrights are carried at the lower of unamortized cost or net realizable value. The current and non-current portions of licensed copyrights of video content are recorded in “Other current assets, net” or “Intangible assets, net,” respectively. Licensed copyrights include non-exclusive and exclusive content. For non-exclusive licensed copyrights, the Company only has the right to broadcast the content on its internet platform. For exclusive licensed copyrights, in addition to the broadcasting rights, the Company also has the right to sublicense the content to third parties. Non-exclusive licensed copyrights, mainly comprising of newly released movies, television series and seasonal variety shows, are generally amortized using an accelerated method based on historical viewership consumption patterns. Other non-exclusive licensed copyrights, mainly comprising of library movies, television series and variety shows and certain non-episodic features, are amortized on a straight-line basis, as the consumption pattern based on historical viewing data supports this amortization method. Estimates of the consumption patterns for licensed copyrights are reviewed periodically and revised, if necessary. The major factors that impact the viewership consumption patterns include film box office, ratings for television series and variety shows, user traffic on our platforms, placement schedule, user tastes and preferences, emerging cultural trends, merchandising and marketing efforts. Revisions to the amortization pattern are accounted for as a change in accounting estimate prospectively in accordance with ASC Topic 250, Accounting Changes and Error Corrections (“ASC 250”). The purchase cost of exclusive licensed copyrights includes the right to broadcast and the right to sublicense to third parties. The Company allocates content cost to these two rights when the exclusive licensed copyrights are initially recognized, based on the relative proportion of our estimate of the total revenues that will be generated by each right. Content costs related to the broadcasting right, which is the portion of an exclusive licensed copyright that generates direct and indirect advertising and membership revenues, are amortized in accordance with ASC Subtopic 920-350, Entertainment-Broadcasters: Intangibles—Goodwill and Other (“ASC 920-350”), using the same method as non-exclusive licensed copyrights described above. For the right to sublicense to third parties, which is the portion of an exclusive licensed copyright that generates direct revenues, are amortized in accordance with ASC Topic 926, Entertainment—Films (“ASC 926”) using an individual-film-forecast-computation method, which amortizes such costs based on the ratio of the actual sublicensing revenues generated for the current period to the total sublicensing revenues estimated to be generated by the sublicensing right. The Company reviews the forecasted total direct revenues on a periodic basis and any change in estimate will result in a revised fraction applied to the net carrying amount of the right to sublicense. The difference between expenses determined using the new estimates and any amounts previously expensed during the fiscal year is recognized in the period of revision. On a periodic basis, the Company evaluates the program usefulness of the broadcasting rights of its licensed copyrights and record such rights at the lower of unamortized cost or estimated net realizable value pursuant to the guidance in ASC 920-350. When there is a change in the expected usage of licensed copyrights, the Company estimates net realizable value of licensed copyrights to determine if any impairment exists. Net realizable value is determined by estimating the expected cash flows generated from the provision of online advertising and membership services, less any direct costs, over the remaining useful lives of non-exclusive licensedcopyrights. The Company estimates advertising and membership cash flows for each category of content. Estimates that impact advertising and membership cash flows include anticipated levels of demand for the Company’s online advertising and membership services and the expected selling prices of the Company’s advertisements and memberships. For the right to sublicense to third parties, the Company assesses recoverability in accordance with ASC Subtopic 926-20, Entertainment—Films: Other Assets—Film Costs (“ASC 926-20”). The Company recognized impairment charges on licensed copyrights of RMB212 million, RMB390 million and RMB181 million (US$26 million) for the years ended December 31, 2016, 2017 and 2018, respectively. Goodwill and Intangible Assets Goodwill The Company assesses goodwill for impairment in accordance with ASC Subtopic 350-20, Intangibles—Goodwill and Other: Goodwill (“ASC 350-20”), which requires that goodwill to be tested for impairment at the reporting unit level at least annually and more frequently upon the occurrence of certain events, as defined by ASC 350-20. As of December 31, 2017 and 2018, the Company has two reporting units, consisting of Baidu Core and iQIYI. The Company has the option to assess qualitative factors first to determine whether it is necessary to perform the two-step test in accordance with ASC 350-20. If the Company believes, as a result of the qualitative assessment, that it is more-likely-than-not that the fair value of the reporting unit is less than its carrying amount, the two-step quantitative impairment test described above is required. Otherwise, no further testing is required. In the qualitative assessment, the Company considers primary factors such as industry and market considerations, overall financial performance of the reporting unit, and other specific information related to the operations. In performing the two-stepquantitative impairment test, the first step compares the carrying amount of the reporting unit to the fair value of the reporting unit based on either quoted market prices of the ordinary shares or estimated fair value using a combination of the income approach and the market approach. If the fair value of the reporting unit exceeds the carrying value of the reporting unit, goodwill is not impaired and the Company is not required to perform further testing. If the carrying value of the reporting unit exceeds the fair value of the reporting unit, then the Company must perform the second step of the impairment test in order to determine the implied fair value of the reporting unit’s goodwill. The fair value of the reporting unit is allocated to its assets and liabilities in a manner similar to a purchase price allocation in order to determine the implied fair value of the reporting unit goodwill. If the carrying amount of the goodwill is greater than its implied fair value, the excess is recognized as an impairment loss.
The Company performed qualitative assessments for the reporting unit of Baidu Core in 2017 and 2018. Based on the requirements of ASC 350-20, the Company evaluated all relevant factors including, but not limited to, macroeconomic conditions, industry and market conditions, financial performance, and the share price of the Company. The Company weighed all factors in their entirety and concluded that it was not more-likely-than-not the fair value was less than the carrying amount of Baidu Core, and further impairment testing on goodwill was unnecessary as of December 31, 2017 and 2018. The Company elected to assess goodwill for impairment using the two-step process for the reporting unit of iQIYI. Subsequent to iQIYI’s IPO, the Company primarily considered the quoted market price of iQIYI’s share to determine the fair value of the reporting unit. Before its IPO, significant management judgment was involved in determining these estimates and assumptions, and actual results may differ from those used in valuations. Changes in these estimates and assumptions could materially affect the determination of fair value for each reporting unit which could trigger future impairment. The judgment in estimating the fair value of a reporting unit includes forecasts of future cash flows, which are based on our best estimate of future revenue and operating expenses growth rates, future capital expenditures and working capital levels, as well as an appropriate discount rate determined by a weighted average cost of capital approach and the selection of comparable companies operating in similar businesses. The Company also reviewed observable market data to assess the reasonableness of assumptions such as discount rate, operating margins, and working capital levels. As of December 31, 2017 and 2018, the fair value of iQIYI exceeded its carrying amount, and therefore goodwill related to the iQIYI reporting unit was not impaired and the Company was not required to perform further testing. Intangible assets Intangible assets with finite lives are carried at cost less accumulated amortization. Land use rights are amortized using a straight-line method over the shorter of their estimated useful lives or the terms of the related land use right contracts. All other intangible assets with finite lives are amortized using the straight-line method over the estimated useful lives, except for the sublicensing rights and certain licensed copyrights. Intangible assets have weighted average useful lives from the date of purchase as follows:
Intangible assets with an indefinite useful life are not amortized and are tested for impairment annually or more frequently if events or changes in circumstances indicate that they might be impaired in accordance with ASC Subtopic 350-30, Intangibles-Goodwill and Other: General Intangibles Other than Goodwill (“ASC 350-30”). Produced Content, net The Company produces and contracts external parties to produce films and episodic series to exhibit on its websites. Produced content includes direct production costs, production overhead and acquisition costs and is stated at the lower of unamortized cost or estimated fair value. Produced content also includes cash expenditures made to acquire a proportionate share of certain rights to films including profit sharing, distribution and/or other rights. Produced content exceeding the total revenues to be earned (“ultimate revenue”) is expensed as cost of revenues. The Company uses the individual-film-forecast-computation method and amortizes the produced content based on the ratio of current period actual revenue (numerator) to estimated remaining unrecognized ultimate revenue as of the beginning of the fiscal year (denominator) in accordance with ASC 926-20. The Company reviews the forecasted ultimate revenues on a periodic basis and any change in estimate will result in a revised fraction applied to the net carrying amount of the right to sublicense, and the difference between expenses determined using the new estimates and any amounts previously expensed during the fiscal year is recognized in the period of revision. The Company reviews unamortized produced content costs for impairment whenever events or circumstances indicate that the fair value of the produced content may be less than its unamortized cost. Produced content was presented as “Other non-current assets” on the consolidated balance sheets, the carrying amounts were RMB1.6 billion and RMB3.7 billion (US$543 million), respectively, as of December 31, 2017 and 2018. Impairment of Long-Lived Assets Other Than Goodwill The Company evaluates long-lived assets, such as fixed assets and purchased or internally developed intangible assets with finite lives, for impairment whenever events or changes in circumstances indicate the carrying value of an asset may not be recoverable in accordance with ASC Topic 360, Property, Plant and Equipment. When such events occur, the Company assesses the recoverability of the asset group based on the undiscounted future cash flow the asset group is expected to generate and recognizes an impairment loss when estimated undiscounted future cash flow expected to result from the use of the asset group plus net proceeds expected from disposition of the asset group, if any, is less than the carrying value of the asset group. If the Company identifies an impairment, the Company reduces the carrying amount of the asset group to its estimated fair value based on a discounted cash flow approach or, when available and appropriate, to comparable market values. The Company uses estimates and judgments in its impairment tests and if different estimates or judgments had been utilized, the timing or the amount of any impairment charges could be different. Asset groups to be disposed of would be reported at the lower of the carrying amount or fair value less costs to sell, and no longer depreciated. The assets and liabilities of a disposal group classified as held for sale would be presented separately in the appropriate asset and liability sections of the consolidated balance sheets. Revenue Recognition The Company adopted ASC Topic 606 Revenue from Contracts with Customers (“ASC 606”), from January 1, 2018, using the modified retrospective method. Revenues for the year ended December 31, 2018 were presented under ASC 606, and revenues for the years ended December 31, 2017 and 2016 were not adjusted and continue to be presented under ASC Topic 605, Revenue Recognition. The cumulative effect of adopting ASC 606 resulted in an increase of RMB933 million (US$136 million) to the opening balance of retained earnings at January 1, 2018, which is primarily related to the Company’s online marketing revenues. Revenue is recognized when control of promised goods or services is transferred to the Company’s customers in an amount of consideration to which an entity expects to be entitled to in exchange for those goods or services. Starting from January 1, 2018, value added taxes (“VAT”) was reclassified from cost of revenue to net against revenues in accordance with ASC 606. The Company recognized VAT of RMB3.9 billion, RMB4.8 billion and RMB6.1 billion (US$884 million) for the years ended December 31, 2016, 2017 and 2018, respectively. Other than the presentation of VAT, the impact from adopting ASC 606 was not material to the Company’s consolidated financial statements as of and for the year ended December 31, 2018.
The following table presents the Company’s revenues disaggregated by revenue source:
The Company’s revenue recognition policies effective on the adoption date of ASC 606 are as follows: Performance-based online marketing services Cost-per-click The Company’s auction-based P4P platform enables customers to bid for priority placement of their paid sponsored links. The P4P platform enables customers to reach users who search for information related to their products or services. The P4P services include search-based online marketing services and feed-based online marketing services. The P4P online marketing customers may choose to set a daily limit on the amount spent and may also choose to target only users accessing our website from specified regions in China and/or during a specific time period of the day. Besides the Company’s traditional search-based P4P services, the Company also displays feed-based marketing to target the right feed users based on user data on the Company’s platform. Customers pay the Company when a targeted user clicks the feed-based marketing and are directed to its platforms. Revenue is recognized when all of the revenue recognition criteria are met, which is generally when a user clicks on one of the customer-sponsored links or feed-based marketing. Other performance-based online marketing services To the extent the Company provides online marketing services based on performance criteria other than cost-per-click, such as the number of downloads (and user registration) of mobile apps and the pre-determined ratios of completed transaction volumes, revenue is recognized when the specified performance criteria are met along with the satisfaction of other applicable revenue recognition criteria. Display advertisements The Company provides display-based online advertising services to its customers by integrating text description, image and video, and displaying the advertisement in a prominent position of the search result page, vertical search products or Baidu Feed. The Company recognizes revenue on a pro-rata basis over the contractual term for cost per time advertising arrangements commencing on the date the customer’s advertisement is displayed on the Company’s platform, or based on the number of times that the advertisement has been displayed for cost per thousand impressions advertising arrangements. Online marketing services involving Baidu Union Baidu Union is a program through which the Company expands distribution of its customers’ sponsored links or advertisements by leveraging the traffic of Baidu Union partners’ internet properties. The Company makes payments to Baidu Union partners for the acquisition of traffic. The Company is the principal in these transactions, as it is primarily responsible for fulfilling the service, has discretion in establishing pricing and controls the advertising inventory before the transfer to customers. Therefore, revenue is recognized on a gross basis on the amount of fees it billed to its customers. Payments made to Baidu Union partners are recorded as traffic acquisition costs, which are included in “Cost of revenues” in the consolidated statements of comprehensive income. Membership services The Company offers membership services that provide subscribing members access to stream a library of premium content or personal cloud service in exchange for upfront non-refundable membership fees. When the receipt of membership fees is for services to be delivered over a period of time, the receipt is initially recorded as deferred revenue and revenue is recognized ratably over the membership period as services are rendered. Membership services revenue also includes fees earned from on-demand content purchases made by members and the sale of the right to services such as other memberships, which the Company acquires and controls before they are transferred to the customers. Content distribution The Company generates revenues from sub-licensing content licensed from third party vendors for cash and through nonmonetary exchanges mainly with other online video broadcasting companies. The exclusive licensing agreements the Company enters into with vendors has a definitive license period and provides the Company the rights to sub-license these contents to other third parties. The Company enters into a non-exclusive sub-licenseagreement with a sub-licensee for a period that falls within the original exclusive license period. For cash sub-licensing transactions, the Company receives the sub-license fee upfront under the sub-licensing arrangements and does not have any future obligation once it has provided the underlying content to the sub-licensee (which is provided at or before the beginning of the sub-license period). The sub-license fees are recognized in accordance with ASC 606 and represents a license of functional intellectual property that grants a right to use the Company’s licensed copyrights, and recognized at the point in time when the licensed copyright is made available for the customer’s use and benefit. The Company also enters into nonmonetary transactions to exchange online broadcasting rights of licensed copyrights with other online video broadcasting companies from time to time. The exchanged licensed copyrights provide rights for each party to broadcast the licensed copyrights received on its own website only. Each transferring party retains the right to continue broadcasting the exclusive content on its own website and/or sublicense the rights to the content it surrendered in the exchange. The Company accounts for these nonmonetary exchanges in accordance with ASC 606, and records the transaction based on the fair value of the asset received starting from January 1, 2018. Barter sublicensing revenue are recognized in accordance with the same ASC 606 criteria above. The Company estimates the fair value of the licensed copyrights received based on various factors, including broadcasting schedule, cast and crew, theme and popularity, box office and market share of counterparties to the exchange. The attributable cost of cash sublicensing transactions, whether for cash or through nonmonetary exchanges, is recognized as cost of revenues through the amortization of the sublicensing right component of the exclusive licensed copyright, computed using the individual-film-forecast-computation method in accordance with ASC 926. The Company recognized barter sublicensing revenues of RMB382 million, RMB763 million and RMB1.1 billion (US$158 million) and related costs of RMB363 million, RMB650 million and RMB1.0 billion (US$149 million) for the years ended December 31, 2016, 2017 and 2018, respectively. Barter transactions The Company engages in certain barter transactions other than licensed copyrights of video contents, such as advertising, from time to time. The transaction price of the nonmonetary consideration is measured at fair value at contract inception. If fair value cannot be reasonably estimated, the Company measures the consideration indirectly by reference to the standalone selling price of the services promised to the customer in exchange for the consideration. Revenues recognized on advertising barter transactions were immaterial for the years ended December 31, 2016, 2017 and 2018. Financial services The Company offers financial services which include provision of installment payment services to consumers and wealth management services to third-party investors. Interest income earned from provision of financial services is reported as “Other revenues” and reported on a net basis after deduction of related interest costs incurred. The Company recognized gross interest income of RMB3.5 billion and RMB3.3 billion (US$483 million) and interest costs of RMB1.9 billion and RMB1.6 billion (US$232 million) for the years ended December 31, 2017 and 2018, respectively. Gross interest income and interest costs recognized for the year ended December 31, 2016 were insignificant. The financial services business was disposed of in August 2018 (Note 4). Other revenue recognition related policies For arrangements that include multiple performance obligations, primarily for advertisements to be displayed in different spots, placed under different forms and displayed at different times, the Company would evaluate all the performance obligations in the arrangement to determine whether each performance obligation is distinct. Consideration is allocated to each performance obligation based on its standalone selling price. If a promised good or service does not meet the criteria to be considered distinct, it is combined with other promised goods or services until a distinct bundle of goods or services exists. Timing of revenue recognition may differ from the timing of invoicing to customers. For certain services customers are required to pay before the services are delivered to the customer. When either party to a revenue contract has performed, the Company recognizes a contract asset or a contract liability in the consolidated balance sheet, depending on the relationship between the entity’s performance and the customer’s payment. Contract liabilities were mainly related to fees for membership services to be provided over the membership period, which were presented as deferred revenue on the consolidated balance sheets. The increase in deferred revenue as compared to the year ended December 31, 2017 is a result of the increase in consideration received from the Company’s customers. The opening balance of contract assets were RMB832 million as of January 1, 2018. As of December 31, 2018, contract assets of RMB1.4 billion (US$206 million), net of allowance for doubtful accounts of RMB21 million (US$3 million) were recognized and included in “Other current assets, net” on the consolidated balance sheet.
The Company does not disclose the value of unsatisfied performance obligations for (i) contracts with an original expected length of one year or less and (ii) contracts for which the Company recognizes revenue at the amount to which it has the right to invoice for services performed. The Company provides sales incentives to customers which entitle them to receive reductions in the price of the online marketing services by meeting certain cumulative consumption requirements. The Company accounts for these incentives granted to customers as variable consideration and net against revenue. The amount of variable consideration is measured based on the most likely amount of incentives to be provided to customers. Cost of Revenues Cost of revenues consists primarily of traffic acquisition costs, bandwidth costs, depreciation, content costs, payroll and related costs of operations. Starting from January 1, 2018, VAT was recorded net against revenue instead of as cost of revenue. Traffic acquisition costs represent the amounts paid or payable to Baidu Union partners who direct search queries to the Company’s websites or distribute the Company’s customers’ paid links through their properties. These payments are primarily based on revenue sharing arrangements under which the Company pays its Baidu Union partners and other business partners a percentage of the fees it earns from its online marketing customers. Advertising and Promotional Expenses Advertising and promotional expenses, including advertisements through various forms of media and kinds of marketing and promotional activities, are included in “Selling, general and administrative expense” in the consolidated statements of comprehensive income (loss) and are expensed when incurred. Advertising and promotional expenses for the years ended December 31, 2016, 2017 and 2018 were RMB7.7 billion, RMB4.6 billion and RMB10.1 billion (US$1.5 billion), respectively. Government Subsidies Government subsidies primarily consist of financial subsidies received from provincial and local governments for operating a business in their jurisdictions and compliance with specific policies promoted by the local governments. For certain government subsidies, there are no defined rules and regulations to govern the criteria necessary for companies to receive such benefits, and the amount of financial subsidy is determined at the discretion of the relevant government authorities. The government subsidies of non-operating nature with no further conditions to be met are recorded as non-operating income in “Other income, net” when received. The government subsidies with certain operating conditions are recorded as “deferred income” when received and will be recorded as operating income when the conditions are met. Leases Leases are classified as either capital or operating leases. Leases that transfer substantially all the benefits and risks incidental to the ownership of assets are accounted for as capital leases as if there was an acquisition of an asset and incurrence of an obligation at the inception of the lease. All other leases are accounted for as operating leases wherein rental payments are expensed as incurred. Income Taxes The Company recognizes income taxes under the liability method. Deferred income taxes are recognized for differences between the financial reporting and tax bases of assets and liabilities at enacted tax rates in effect for the years in which the differences are expected to reverse. The Company records a valuation allowance against the amount of deferred tax assets that it determines is not more-likely-than-not to be realized. The effect on deferred taxes of a change in tax rates is recognized in earnings in the period that includes the enactment date. The Company applies the provisions of ASC Topic 740, Income Taxes (“ASC 740”), in accounting for uncertainty in income taxes. ASC 740 clarified the accounting for uncertainty in income taxes by prescribing the recognition threshold a tax position is required to meet before being recognized in the financial statements. The Company has elected to classify interest and penalties related to an uncertain tax position (if and when required) as part of income tax expense in the consolidated statements of comprehensive income. As of and for the years ended December 31, 2016, 2017 and 2018, the amounts of unrecognized tax benefits as well as interest and penalties associated with uncertainty in income taxes were insignificant. Share-based Compensation The Company accounts for share-based compensation in accordance with ASC Topic 718, Compensation-Stock Compensation (“ASC 718”). The Company has elected to recognize share-based compensation using the straight-line method for all share-based awards issued with no performance conditions. For awards with performance conditions, compensation cost is recognized on an accelerated basis if it is probable that the performance condition will be achieved. Forfeitures are estimated based on historical experience and are periodically reviewed. Cancellation of an award accompanied by the concurrent grant of a replacement award is accounted for as a modification of the terms of the cancelled award (“modified awards”). The compensation costs associated with the modified awards are recognized if either the original vesting condition or the new vesting condition is achieved. Total recognized compensation cost for the awards is at least equal to the fair value of the awards at the grant date unless at the date of the modification the performance or service conditions of the original awards are not expected to be satisfied. The incremental compensation cost is measured as the excess of the fair value of the replacement award over the fair value of the cancelled award at the cancellation date. Therefore, in relation to the modified awards, the Company recognizes share-based compensation over the vesting periods of the replacement award, which comprises, (i) the amortization of the incremental portion of share-based compensation over the remaining vesting term and (ii) any unrecognized compensation cost of the original award, using either the original term or the new term, whichever results in higher expenses for each reporting period. The Company accounts for share awards issued to non-employees in accordance with the provisions of ASC Subtopic 505-50, Equity: Equity-based Payments to Non-Employees. The Company uses the Black-Scholes-Merton option pricing model method to measure the value of options granted to non-employees at each vesting date to determine the appropriate charge to share-based compensation. ASC 718 requires share-based compensation to be presented in the same manner as cash compensation rather than as a separate line item. Earnings Per Share (“EPS”) The Company computes earnings per Class A and Class B ordinary shares in accordance with ASC Topic 260, Earnings Per Share (“ASC 260”), using the two-class method. Under the provisions of ASC 260, basic earnings per share is computed using the weighted average number of ordinary shares outstanding during the period except that it does not include unvested ordinary shares subject to repurchase or cancellation. The Company adjusts for the accretion of the redeemable noncontrolling interests in the calculation of income available to ordinary shareholders of the Company used in the earnings per share calculation. Diluted earnings per share is computed using the weighted average number of ordinary shares and, if dilutive, potential ordinary shares outstanding during the period. Potentially dilutive securities such as convertible senior notes have been excluded from the computation of diluted net income per share if their inclusion is anti-dilutive. Potential ordinary shares consist of the incremental ordinary shares issuable upon the exercise of stock options, restricted shares subject to forfeiture, and contracts that may be settled in the Company’s stock or cash. The dilutive effect of outstanding stock options and restricted shares is reflected in diluted earnings per share by application of the treasury stock method. The computation of the diluted earnings per Class A ordinary share assumes the conversion of Class B ordinary shares to Class A ordinary shares, while diluted earnings per Class B ordinary share does not assume the conversion of such shares. The liquidation and dividend rights of the holders of the Company’s Class A and Class B ordinary shares are identical, except with respect to voting rights. As a result, and in accordance with ASC 260, the undistributed earnings for each year are allocated based on the contractual participation rights of the Class A and Class B ordinary shares as if the earnings for the year had been distributed. As the liquidation and dividend rights are identical, the undistributed earnings are allocated on a proportionate basis. Further, as the conversion of Class B ordinary shares is assumed in the computation of the diluted earnings per Class A ordinary share, the undistributed earnings are equal to net income for that computation. For the purposes of calculating the Company’s basic and diluted earnings per Class A and Class B ordinary shares, the ordinary shares relating to the options that were exercised are assumed to have been outstanding from the date of exercise of such options. Contingencies The Company records accruals for certain of its outstanding legal proceedings or claims when it is probable that a liability will be incurred and the amount of loss can be reasonably estimated. The Company evaluates, on a quarterly basis, developments in legal proceedings or claims that could affect the amount of any accrual, as well as any developments that would make a loss contingency both probable and reasonably estimable. The Company discloses the amount of the accrual if it is material. When a loss contingency is not both probable and estimable, the Company does not record an accrued liability but discloses the nature and the amount of the claim, if material. However, if the loss (or an additional loss in excess of the accrual) is at least reasonably possible, then the Company discloses an estimate of the loss or range of loss, unless it is immaterial or an estimate cannot be made. The assessment of whether a loss is probable or reasonably possible, and whether the loss or a range of loss is estimable, often involves complex judgments about future events. Management is often unable to estimate the loss or a range of loss, particularly where (i) the damages sought are indeterminate, (ii) the proceedings are in the early stages, or (iii) there is a lack of clear or consistent interpretation of laws specific to the industry-specific complaints among different jurisdictions. In such cases, there is considerable uncertainty regarding the timing or ultimate resolution of such matters, including eventual loss, fine, penalty or business impact, if any. Concentration of Risks Concentration of credit risk Financial instruments that potentially subject the Company to significant concentration of credit risk primarily consist of cash and cash equivalents, restricted cash, short-term investments, accounts receivable, and amounts due from related parties. As of December 31, 2018, the Company has RMB141.5 billion (US$20.6 billion) in cash and cash equivalents, restricted cash, and short-term investments, 94% and 6% of which are held by financial institutions in the PRC and international financial institutions outside of the PRC, respectively. The Company’s total cash and cash equivalents, restricted cash, and short-term investments held at four financial institutions in the PRC exceeded 10%, representing 37%, 15%, 13%, and 11% of the Company’s total cash and cash equivalents, restricted cash, and short-term investments as of December 31, 2018, respectively. PRC state-owned banks, such as Bank of China, are subject to a series of risk control regulatory standards, and PRC bank regulatory authorities are empowered to take over the operation and management when any of those banks faces a material credit crisis. The Company does not foresee substantial credit risk with respect to cash and cash equivalents, restricted cash and short-term investments held at the PRC state-owned banks. Meanwhile, China does not have an official deposit insurance program, nor does it have an agency similar to what was the Federal Deposit Insurance Corporation (FDIC) in the U.S. In the event of bankruptcy of one of the financial institutions in which the Company has deposits or investments, it may be unlikely to claim its deposits or investments back in full. The Company selected reputable international financial institutions with high rating rates to place its foreign currencies. The Company regularly monitors the rating of the international financial institutions to avoid any potential defaults. There has been no recent history of default in relation to these financial institutions. Accounts receivable are typically unsecured and derived from revenue earned from customers and agents in China, which are exposed to credit risk. The risk is mitigated by credit evaluations the Company performs on its customers and its ongoing monitoring process of outstanding balances. The Company maintains reserves for estimated credit losses and these losses have generally been within its expectations. As of December 31, 2017 and 2018, the Company had no single customer with a receivable balance exceeding 10% of the total accounts receivable balance. No customer or any Baidu Union partner generated greater than 10% of total revenues in any of the three years presented. Amounts due from related parties are typically unsecured. In evaluating the collectability of the amounts due from related parties balance, the Company considers many factors, including the related parties’ repayment history and their credit-worthiness. An allowance for doubtful accounts is made when collection of the full amount is no longer probable. Business and economic risks The Company participates in a dynamic high technology industry and believes that changes in any of the following areas could have a material adverse effect on the Company’s future financial position, results of operations or cash flows: changes in the overall demand for services and products; changes in business offerings; competitive pressures due to new entrants; advances and new trends in new technologies and industry standards; changes in bandwidth suppliers; changes in certain strategic relationships or customer relationships; regulatory considerations; copyright regulations; brand maintenance and enhancement; and risks associated with the Company’s ability to attract and retain employees necessary to support its growth. The Company’s operations could be adversely affected by significant political, economic and social uncertainties in the PRC. Currency convertibility risk Substantially all of the Company’s businesses are transacted in RMB, which is not freely convertible into foreign currencies. All foreign exchange transactions take place either through Bank of China or other banks authorized to buy and sell foreign currencies at the exchange rates quoted by the People’s Bank of China. Approval of foreign currency payments by the People’s Bank of China or other regulatory institutions requires submitting a payment application form together with suppliers’ invoices, shipping documents and signed contracts.
Foreign currency exchange rate risk The functional currency and the reporting currency of the Company are the US$ and the RMB, respectively. The Company’s exposure to foreign currency exchange rate risk primarily relates to cash and cash equivalents, restricted cash, short-term investments, long-term investments, notes payable and convertible senior notes denominated in the US$. On June 19, 2010, the People’s Bank of China announced the end of the RMB’s de facto peg to the US$, a policy which was instituted in late 2008 in the face of the global financial crisis, to further reform the RMB exchange rate regime and to enhance the RMB’s exchange rate flexibility. On March 15, 2014, the People’s Bank of China announced the widening of the daily trading band for RMB against US$. The appreciation of the US$ against the RMB was approximately 5.67% in 2018. Most of the revenues and costs of the Company are denominated in RMB, while a portion of cash and cash equivalents, restricted cash, short-term investments, long-term investments, notes payable and convertible senior notes are denominated in U.S. dollars. It is difficult to predict how market forces or PRC or U.S. government policy may impact the exchange rate between the Renminbi and the U.S. dollar in the future. Any significant fluctuation of the valuation of RMB may materially affect the Company’s cash flows, revenues, earnings and financial position, and the value of, and any dividends payable on, the ADS in US$. Derivative Instruments ASC Topic 815, Derivatives and Hedging (“ASC 815”), requires all contracts which meet the definition of a derivative to be recognized on the balance sheet as either assets or liabilities and recorded at fair value. Changes in the fair value of derivative financial instruments are either recognized periodically in earnings or in other comprehensive income depending on the use of the derivative and whether it qualifies for hedge accounting. Changes in fair values of derivatives not qualified as hedges are reported in earnings. Recent Accounting Pronouncements In February 2016, the FASB issued ASU No. 2016-02, Leases (“ASU 2016-02”). ASU 2016-02 specifies the accounting for leases. For operating leases, ASU 2016-02 requires a lessee to recognize a right-of-use asset and a lease liability, initially measured at the present value of the lease payments, in its balance sheet. The standard also requires a lessee to recognize a single lease cost, calculated so that the cost of the lease is allocated over the lease term, on a generally straight-line basis. ASU 2016-02 is effective for public business entities for annual reporting periods and interim periods within those years beginning after December 15, 2018. The Company will adopt ASU 2016-02 on January 1, 2019 using by modified retrospective method and will not restate comparable periods. The Company will elect the package of practical expedients permitted under the transition guidance, which allow the Company to carry forward the historical lease classification, the assessment whether a contract is or contains a lease and initial direct costs for any leases that exist prior to adoption of the new standard. The Company will also elect the practical expedient not to separate lease and non-lease components for certain classes of underlying assets and the short-term lease exemption for contracts with lease terms of 12 months or less. Operating leases related to land use right, offices and internet data center (“IDC”) facilities will be subject to ASU 2016-02 and right-of-use assets and operating lease liabilities will be recognized on the Company’s consolidated balance sheet. The Company currently believes the most significant change will be related to the recognition of right-of-use assets and lease liabilities on the Company’s balance sheet for certain in-scope operating leases. The Company does not expect any material impact on net assets and the consolidated statement of comprehensive income as a result of adopting the new standard. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”) which requires the measurement and recognition of expected credit losses for financial assets held at amortized cost. ASU 2016-13 replaces the existing incurred loss impairment model with an expected loss methodology, which will result in more timely recognition of credit losses. ASU 2016-13 is effective for annual reporting periods, and interim periods within those years, beginning after December 15, 2019. The Company is currently in the process of evaluating the impact of the adoption of ASU 2016-13 on its consolidated financial statements. In June 2018, the FASB issued ASU No. 2018-07, Compensation—Stock Compensation (Topic 718)：Improvements to Nonemployee Share-Based Payment Accounting to simplify the accounting for share-based payments to nonemployees (“ASU 2018-07”) by aligning it with the accounting for share-based payments to employees, with certain exceptions. Under the guidance, the measurement of equity-classified nonemployee awards will be fixed at the grant date, which may lower their cost and reduce volatility in the income statement. The guidance is effective for public business entities in annual periods beginning after December 15, 2018, and interim periods within those years. Early adoption is permitted, including in an interim period. The ASU 2018-07 will impact the accounting of the share-based awards granted to non-employees and the Company does not expect a significant impact on its consolidated financial statements. In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement (“ASU 2018-13”) which eliminates, adds and modifies certain disclosure requirements for fair value measurements. Under the guidance, public companies will be required to disclose the range and weighted average used to develop significant unobservable inputs for Level 3 fair value measurements. The guidance is effective for all entities for fiscal years beginning after December 15, 2019 and for interim periods within those fiscal years, but entities are permitted to early adopt either the entire standard or only the provisions that eliminate or modify the requirements. The Company does not expect a significant impact on its consolidated financial statements. In March 2019, the FASB issued ASU 2019-02, Improvements to Accounting for Costs of Films and License Agreements for Program Materials (“ASU 2019-02”) which improves GAAP by aligning the accounting for production costs of an episodic television series with the accounting for production costs of films by removing the content distinction for capitalization. In addition, ASU 2019-02 requires that an entity test a film or license agreement for program material within the scope of ASC 920-350 for impairment at a film group level when the film or license agreement is predominantly monetized with other films and/or license agreements. The presentation and disclosure requirements in ASU 2019-02 also increase the transparency of information provided to users of financial statements about produced and licensed content. This update will be effective for the Company’s fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. Early adoption is permitted. The Company is currently in the process of evaluating the effect that the adoption of ASU 2019-02 will have on the consolidated financial statements and related disclosures. |

| Business Combinations |
Business combinations in 2018: During the year ended December 31, 2018, the Company completed several business combinations, to complement its existing businesses and achieve synergies. The acquired entities individually and in aggregate were in significant. Results of the acquired entities’ operations have been included in the Company’s consolidated financial statements since the acquisition dates.
The aggregate purchase price allocation includes acquisition of certain acquirees, which were equity method investees of the Company prior to the acquisitions. In aggregate, a re-measurement gain relating to the Company’s pre-existing equity interest of RMB630 million (US$92 million) was recognized during the year ended December 31, 2018. The Company applied the equity method of accounting by recognizing its share of the profit or loss in these equity method investees up to their respective dates of acquisition. Goodwill, which is non-deductible for tax purpose, is primarily attributable to the synergies expected to be achieved from the acquisitions. Neither the results of operations since the acquisition dates nor the pro forma results of operations of the acquirees were presented because the effects of these business combinations, individually and in the aggregate, were not significant to the Company’s consolidated results of operations. The valuations used in the purchase price allocation described above were determined by the Company with the assistance of independent third party valuation firms. The valuation reports considered generally accepted valuation methodologies such as the income, market and cost approaches. As the acquirees are all private companies, the fair value estimates of pre-existing equity method investments or noncontrolling interests are based on significant inputs that market participants would consider, which mainly include (a) discount rates, (b) a projected terminal values based on future cash flows (c) financial multiples of companies in the same industries and (d) adjustments for lack of control or lack of marketability. |

Long-term Investments Equity investments at fair value with readily determinable fair value Equity investments at fair value with readily determinable fair value represent investments in the equity securities of publicly listed companies for which the Company does not have significant influence. The equity investments were accounted for as available-for-sale equity investments prior to the adoption of ASC 321. Starting in January 1, 2018 after adopting ASC 321, these investments were classified as equity investments at fair value with readily determinable fair value and reported at fair value. Changes in fair value are recognized in earnings, instead of accumulated other comprehensive income. Equity investments at fair value without readily determinable fair value Equity investments at fair value without readily determinable fair value were accounted as cost method investments prior to adopting ASC 321. As of December 31, 2017, the carrying amount of the Company’s cost method investments was RMB21.8 billion. In accordance with ASC 321, the Company elected to use the measurement alternative to measure such investments at cost, less any impairment, plus or minus changes resulting from observable price changes in orderly transactions for identical or similar investments of the same issuer, if any. As of December 31, 2018, the carrying amount of the Company’s equity investments measured at fair value using the measurement alternative was RMB29.3 billion (US$4.3 billion), net of RMB1.3 billion (US$191 million) in accumulated impairment. Impairment charges recognized on equity investments measured at fair value using the measurement alternative was RMB455 million (US$66 million) for the year end December 31, 2018. During the year ended December 31, 2018, certain equity investments were remeasured based on observable price changes in orderly transactions for an identical or similar investment of the same issuer, the aggregate carrying amount of these investments was RMB21.6 billion (US$3.1 billion) as of December 31, 2018. Total unrealized and realized gains and losses of equity securities without readily determinable fair values in 2018 were as follows:
In 2016, the Company exchanged its equity shares of Uber (Cayman), Ltd. (“Uber China”), with Xiaoju Kuaizhi, Inc. (“Didi”), a China based ridesharing company, upon the merger of the two companies. The Company recognized a total gain of RMB2.0 billion in “Other income, net” and the retained investment in Didi was accounted for as a cost method investment. After the adoption of ASC 321, this investment is measured at fair value using the measurement alternative. In May 2017, the Company completed the disposal of its mobile game business to third-party companies, a total gain of RMB923 million was recognized in “Other income, net.” In August 2017, the Company completed the disposal of Xiaodu Life Technology Ltd (“Xiaodu”), a former subsidiary of the Company primarily engaged in the business of takeout delivery services, to Rajax Holding, a China based delivery company. The Company recognized a total gain of RMB4.6 billion in “Other income, net” in 2017. In October 2017, the Company completed the share purchase transaction of China United Network Communication Limited (“China Unicom”), listed telecommunications company in China. The total purchase consideration was RMB7.0 billion in cash with RMB4.0 billion attributable to noncontrolling interest. The investment in China Unicom was held by a non-wholly-owned subsidiary of the Company and was accounted for as a cost method investment due to a three-year holding requirement before adopting ASC 321. Subsequent to the adoption of ASC 321 it was accounted as an equity investments at fair value using the measurement alternative. Equity method investments Equity Investment in Ctrip.com International, Ltd. (“Ctrip”) As of December 31, 2018, the Company held approximately 19% of Ctrip’s outstanding shares, which had a fair value of RMB19.6 billion (US$2.8 billion) as of December 31, 2018 , based on the market closing price. The Company is considered to have significant influence over Ctrip and accounts for such investment as an equity method investment in accordance with ASC 323. As of December 31, 2018, the market value of the Company’s investment in Ctrip, based on the market closing price, was below its carrying value. The Company evaluated the investment in Ctrip for impairment, taking into consideration, including, but not limited to, the duration, degree and causes of the decline in stock price, the Company’s intent and ability to hold the investment, recoveries in market price subsequent to the balance sheet date, and Ctrip’s financial performance and near-term prospects. Based on the evaluation, the Company concluded that the decline in market value of the investment in Ctrip did not meet the threshold of other-than-temporary.
The following tables set forth the summarized financial information of Ctrip:
Disposal of financial services business In April 2018, the Company entered into definitive agreements relating to the disposal of its wholly-owned financial services business, which provided consumer credit, wealth management and other financial services. To facilitate the divestiture, the Company conducted a series of legal restructuring and recapitalization of entities conducting the financial services business (“Du Xiaoman”), which were accounted for as transactions under common control. In August 2018, Du Xiaoman issued preferred shares to third-party investors, which resulted in the Company becoming a minority shareholder of Du Xiaoman. Accordingly, Du Xiaoman was deconsolidated from the Group and a disposal gain of RMB5.5 billion (US$803 million) was recognized in “Other income, net,” including RMB4.2 billion (US$604 million) relates to the re-measurement of the Company’s retained investment in Du Xiaoman. The disposal of Du Xiaoman did not meet the definition of a discontinued operation per ASC Subtopic 205-20, Presentation of Financial Statements—Discontinued Operations, as the divestiture did not represent a shift in strategy nor had a major impact to the Group’s operation and financial results. The Company retained an equity interest of 41% on a fully diluted basis, and accounted for Du Xiaoman as an equity method investment in accordance with ASC 323, as it retained significant influence over Du Xiaoman. The carrying amount of the Du Xiaoman investment in excess of the Company’s proportionate interest in Du Xiaoman was recognized as equity method goodwill of RMB3.5 billion (US$512 million), intangible assets of RMB851 million (US$124 million) and related deferred tax liabilities of RMB213 million (US$31 million). During the year ended December 31, 2016, the Company derecognized a group of assets sold to a third party and deconsolidated several subsidiaries due to the loss of a controlling equity interest in the subsidiary or substantive participating rights granted to other minority shareholders of the subsidiaries. An aggregate gain of RMB1.4 billion was recognized in “Other income, net” during the year ended December 31, 2016 accordingly. The Company’s retained interest in these subsidiaries were accounted for as equity method investments. As of December 31, 2017 and 2018, in addition to the aforementioned equity method investments, the Company held other equity method investments through its subsidiaries or VIEs and over which had significant influence. The carrying amount of the Company’s equity method investments, including Ctrip, was RMB31.4 billion and RMB44.1 billion (US$6.4 billion) as of December 31, 2017 and 2018, respectively (see also Note 20). For the year ended December 31, 2018, equity method investments excluding Ctrip held by the Company in aggregate have met the significance criteria as defined under Rule 4-08(g) of Regulation S-X. Financial information for the Company’s equity method investments other than Ctrip are summarized as a group as follow:

The methodology used in the determination of fair values for held-to-maturity debt investments, available-for-sale debt investments, equity investments with readily determinable fair values and other investment securities accounted for at fair value were disclosed in Note 22.

| Loans Payable |
Short-term Loans Short-term loans as of December 31, 2017 and 2018 amounted to RMB1.2 billion and RMB3.0 billion (US$443 million), respectively, which consisted of RMB denominated borrowings from financial institutions in the PRC and were repayable within one year.
As of December 31, 2017 and 2018, the weighted average interest rates for the outstanding borrowings were approximately 4.86% and 4.47%, respectively, and the aggregate amounts of unused lines of credit for short-term loans were RMB360 million and RMB781 million (US$114 million), respectively.
Long-term Loans Baidu In June 2016, the Company entered into a five-year term and revolving facility agreement with a group of 21 syndicated bankers, pursuant to which the Company is entitled to borrow an unsecured US$ denominated floating rate loan of US$1.0 billion with a term of five years and to borrow an unsecured US$ denominated revolving loan of US$1.0 billion for five years. The facility was priced at 110 basis points over LIBOR and is intended for the general working capital of the Company. In June 2016, the Company drew down two tranches of US$250 million each under the facility commitment. In November 2016, the Company drew down another two tranches of US$250 million each under the facility commitment. In connection with the facility agreements, the Company entered into four interest rate swap agreements, pursuant to which the loans would be settled with a fixed annual interest rate of 2.11%, 2.10%, 2.78% and 2.78% respectively, during the respective term of the loans. The interest rate swap agreements met the definition of a derivative in accordance with ASC 815. The derivatives related to the interest rate swap agreements are accounted at fair value and included in “Other non-current assets” on the consolidated balance sheets. iQIYI In April 2017, iQIYI entered into a three-year loan agreement with Bank of China (Shanghai Branch), pursuant to which the Company is entitled to borrow a secured RMB denominated loan of RMB299 million for the general working capital of iQIYI. In April 2017, iQIYI drew down RMB299 million with an interest rate of 4.47%, pursuant to the agreement, the principal shall be repaid by installments from September 2017 to April 2020. RMB15 million was repaid when it became due. The amount repayable within twelve months were classified as “Long-term loans, current portion.” In December 2018, certain supplier invoices selected by iQIYI of RMB525 million (US$76 million) were factored to a financial institution (“the factored receivables”) at a discount. These supplier invoices were recorded as accounts payables in the Company’s consolidated balance sheet. The factored receivables were further transferred to a securitization vehicle, whereby debt securities securitized by the factored receivables. The debt securities were issued to third party investors for the gross proceeds of RMB446 million (US$65 million), with maturities in December 2019 and December 2020. The proceeds raised from issuance of the asset-backed debt securities were used by the financial institution to factor the supplier invoices. At the same time, the credit terms of the iQIYI’s corresponding trade payables were extended to mirror the maturity of the asset-backed debt securities. The securitization vehicle was consolidated because iQIYI was determined to be the primary beneficiary. As of December 31, 2018, the outstanding borrowings from third-party investors was RMB444 million (US$65 million) and the effective interest rate was 7.00%. The balance of RMB74 million (US$11 million) of the loan is repayable within one year and is included in “Long-term loans, current portion” and the remaining balance of RMB370 million (US$54 million) of the loan is included in non-current “Long-term loans” on the consolidated balance sheet. |

| Convertible Notes |
iQIYI 2018 Convertible Notes In January 2017, iQIYI issued US$1.5 billion of convertible notes (the “iQIYI 2018 Convertible Notes”) in a private placement, among which US$300 million was purchased by the Company and the remaining US$1.2 billion was purchased by external investors. The iQIYI 2018 Convertible Notes bear interest at a coupon rate of 1.50% per annum with a maturity date of January 25, 2018. The iQIYI Notes can be converted into preferred shares in a qualified financing or at iQIYI’s election. The conversion option does not meet the definition of a derivative under ASC 815. On October 26, 2017, the US$1.5 billion iQIYI 2018 Convertible Notes and the related accrued interest were converted into 1,014,436,019 iQIYI’s Series G preferred shares. Upon the completion of IPO, all preferred shares were converted into Class A ordinary shares of iQIYI (Note 16). iQIYI 2023 Convertible Notes In December 2018, iQIYI issued US$750 million convertible senior notes due 2023 (“iQIYI 2023 Convertible Notes”). The iQIYI 2023 Convertible Notes are senior, unsecured obligations of iQIYI, and interest is payable semi-annually in cash at a rate of 3.75% per annum with a maturity date of December 1, 2023, unless previously repurchased, redeemed or converted prior to such date. The initial conversion rate of the iQIYI 2023 Convertible Notes is 37.1830 of iQIYI’s ADSs per US$1,000 principal amount of the iQIYI 2023 Convertible Notes. Upon conversion, the Company will pay or deliver to such converting holders, as the case may be, cash, ADSs, or a combination of cash and ADSs, at its election. Concurrently with the issuance of the iQIYI 2023 Convertible Notes, iQIYI purchased a call option on the Company’s ADS with certain counterparties at a price of US$68 million. The capped call exercise price is equal to the initial conversion price of the iQIYI 2023 Convertible Notes and the cap price is US$38.42 per ADS, subject to certain adjustments under the terms of the capped call transactions. The cost of the capped call was recorded as a reduction of the Company’s additional paid-in capital on the consolidated balance sheets with no subsequent changes in fair value be recorded. As the conversion option may be settled entirely or partially in cash at iQIYI’s option, the Company separated the iQIYI 2023 Convertible Notes into liability and equity components in accordance with ASC 470-20, Debt with Conversion and Other Options. The carrying amount of the liability component was calculated by measuring the fair value of a similar liability that does not have an associated conversion feature. The carrying amount of the equity component representing the conversion option was determined by deducting the fair value of the liability component from the initial proceeds and recorded as additional paid-in capital. Debt issuance costs were allocated to the liability and equity components using the same proportions as the proceeds from the iQIYI 2023 Convertible Notes. The difference between the principal amount of the iQIYI 2023 Convertible Notes and the liability component is considered debt discount and is amortized at an effective interest rate of 7.04% to accrete the discounted carrying value of the iQIYI 2023 Convertible Notes to its face value on December 1, 2021, the put date of the iQIYI 2023 Convertible Notes. As of December 31, 2018, the principal amount of the liability component was RMB5.2 billion (US$750 million), unamortized debt discount was RMB446 million (US$65 million). The carrying amount of the equity component was RMB362 million (US$53 million). |

| Income Taxes |
Cayman Islands and BVI Under the current laws of the Cayman Islands and BVI, the Company is not subject to tax on income or capital gains. Additionally, upon payments of dividends by the Company to its shareholders, no Cayman Islands withholding tax will be imposed. Hong Kong Subsidiaries in Hong Kong are subject to Hong Kong Profits Tax rate at 16.5%. They may be exempted from income tax on their foreign-derived income and there are no withholding taxes in Hong Kong on remittance of dividends. Japan As a result of the Japanese tax regulations amendments, the effective income tax rate are approximately 33%, 32% and 31% for the years ended December 31, 2016, 2017 and 2018, respectively. China Effective from January 1, 2008, the PRC’s statutory, Enterprise Income Tax (“EIT”) rate is 25%. Preferential EIT rates at 15% and 10% are available for qualified “High and New Technology Enterprises” (“HNTEs”) and “Key Software Enterprise” (“KSE”), respectively. The HNTE certificate is effective for a period of three years and the KSE is subject to relevant governmental authorities’ annual assessment based on self-assessment supporting documents filed with the tax authorities each year. Baidu Online, Baidu China and Baidu International enjoyed a reduced tax rate of 10% as qualified KSEs in 2016 and 2017. Certain other PRC subsidiaries and VIEs, including Baidu Netcom, are qualified HNTEs and enjoy a reduced tax rate of 15% for the years presented, which will expire in 2019, 2020 and 2021. An entity must file required supporting documents with the tax authorities before using the preferential rates. Whether the entity is entitled to enjoy a preferential rate as a KSE is subject to relevant governmental authorities’ assessment each year. An entity could re-apply for the HNTE certificate when the prior certificate expires. Historically, all of the Company’s subsidiaries and VIEs successfully re-applied for the certificates when the prior ones expired. A certificate for the current year might be obtained in the following year as a result of the stringent inspection and approval process by the governmental authorities. The Company would record an income tax reversal in the year when the certificate is obtained for the over-paid or over-accrued provisional tax in connection with the grant of a more favorable tax rate for the prior year. Under the current EIT Law, dividends for earnings derived from January 1, 2008 and onwards paid by PRC entities to any of their foreign non-resident enterprise investors are subject to a 10% withholding tax. A lower tax rate will be applied if tax treaty or arrangement benefits are available. Under the tax arrangement between the PRC and Hong Kong, the reduced withholding tax rate for dividends paid by PRC entities is 5% provided the Hong Kong investors meet the requirements as stipulated by relevant PRC tax regulations, such as the beneficiary owner test. Capital gains derived from PRC are also subject to a 10% PRC withholding tax. Income (loss) before income taxes consists of:
Except for the investment related gain recognized, the pre-tax losses from non-PRC operations consist primarily of operating costs, administration expenses, interest expenses and share-based compensation expenses. Income taxes consist of:
The reconciliation of the actual income taxes to the amount of tax computed by applying the aforementioned statutory income tax rate to pre-tax income is as follows:
The tax effects of temporary differences that gave rise to the deferred tax balances at December 31, 2017 and 2018 are as follows:
As of December 31, 2018, the Company had tax losses of approximately RMB9.5 billion (US$1.4 billion) deriving from entities in the PRC, Hong Kong and Japan. The tax losses in Japan can be carried forward for nine years to offset future taxable profit. The tax losses in PRC can be carried forward for five years to offset future taxable profit, and the period was extended to 10 years for entities qualified as HNTE in 2018 and thereafter. The tax losses of entities in the PRC and Japan will begin to expire in 2019, if not utilized. The tax losses in Hong Kong can be carried forward without an expiration date. The Company evaluated its income tax uncertainty under ASC 740. ASC 740 clarifies the accounting for uncertainty in income taxes by prescribing the recognition threshold a tax position is required to meet before being recognized in the financial statements. The Company elects to classify interest and penalties related to an uncertain tax position, if and when required, as part of income tax expense in the consolidated statements of comprehensive income. As of and for the years ended December 31, 2017 and 2018, there was no significant impacts from tax uncertainty on the Company’s financial position and result of operations. The Company does not expect the amount of unrecognized tax benefits would increase significantly in the next 12 months. In general, the PRC tax authorities have up to five years to conduct examinations of the tax filings of the Company’s PRC subsidiaries. Accordingly, the PRC subsidiaries’ tax years of 2013 through 2018 remain open to examination by the respective tax authorities. The Company may also be subject to the examinations of the tax filings in other jurisdictions, which are not material to the consolidated financial statements. In 2013, the Company accrued RMB581 million of withholding tax for the potential remittance of earnings from the PRC subsidiaries to their offshore parent companies in the form of dividend distribution, because the Company believes that the underlying dividends will be distributed in the future considering future merger and acquisition activities. The Company did not provide for additional deferred income taxes and foreign withholding taxes on the undistributed earnings of foreign subsidiaries during the years presented on the basis of its intent to permanently reinvest its foreign subsidiaries’ earnings. As of December, 31 2018, the total amount of undistributed earnings from the PRC subsidiaries for which no withholding tax has been accrued was RMB144.4 billion (US$21.0 billion). Determination of the amount of unrecognized deferred tax liability related to these earnings is not practicable. In the case of its VIEs in the PRC, undistributed earnings were insignificant as of each of the balance sheet dates. |

| Commitments and Contingencies |
Capital Commitments The Company’s capital commitments primarily relate to commitments in connection with the expansion and improvement of its network infrastructure and its plan to build additional office buildings and cloud computing based data centers. Total capital commitments contracted but not yet reflected in the financial statements amounted to RMB220 million (US$32 million) as of December 31, 2018. All of the commitments relating to the network infrastructure are to be fulfilled in the next five years and the commitments relating to the office building and cloud computing based data centers will be settled in installments in the following years according to the construction progress. Operating Lease Commitments The Company leases facilities in the PRC under non-cancelable operating leases expiring on different dates. Payments under operating leases are expensed on a straight-line basis over the periods of the respective leases. Total rental expense for offices was RMB494 million, RMB507 million and RMB485 million (US$71 million) for the years ended December 31, 2016, 2017 and 2018, respectively. Total operating lease expense for IDC facilities was RMB4.7 billion, RMB5.6 billion and RMB6.5 billion (US$944 million) for the years ended December 31, 2016, 2017 and 2018 respectively.
Future minimum payments under non-cancelable operating leases with initial terms of one-year or more consist of the following as of December 31, 2018:
The Group’s lease arrangements have no restriction or contingent rents. Certain lease arrangements have escalation clauses and renewal options with advance notice period of several months. Licensed Copyrights and Produced Content Commitments Future minimum payments under non-cancelable agreements for licensed copyrights and produced content consist of the following as of December 31, 2018:
Investment Commitments The Company’s investment commitments primarily relate to capital contributions obligation under certain arrangements. The total investment commitments contracted but not yet reflected in the financial statements amounted to RMB1.4 billion (US$199 million). Guarantees The Company accounts for guarantees in accordance with ASC Topic 460, Guarantees (“ASC 460”). Accordingly, the Company evaluates its guarantees if any to determine whether (a) the guarantee is specifically excluded from the scope of ASC 460, (b) the guarantee is subject to ASC 460 disclosure requirements only, but not subject to the initial recognition and measurement provisions, or (c) the guarantee is required to be recorded in the financial statements at fair value. The corporate by-laws require that the Company indemnify its officers and directors, as well as those who act as directors and officers of other entities at the Company’s request, against expenses, judgments, fines, settlements and other amounts actually and reasonably incurred in connection with any proceedings arising out of their services to the Company. In addition, the Company entered into separate indemnification agreements with each director and each executive officer of the Company that provide for indemnification of these directors and officers under similar circumstances and under additional circumstances. The indemnification obligations are more fully described in the by-laws and the indemnification agreements. The Company purchases standard directors and officers insurance to cover claims or a portion of the claims made against its directors and officers. Since a maximum obligation is not explicitly stated in the Company’s by-laws or in the indemnification agreements and will depend on the facts and circumstances that arise out of any future claims, the overall maximum amount of the obligations cannot be reasonably estimated. Historically, the Company was not required to make payments related to these obligations, and the fair value for these obligations was nil on the consolidated balance sheets as of December 31, 2017 and 2018. Litigation The Group was involved in certain cases pending in various PRC, Japan, U.S. and Brazil courts and arbitration as of December 31, 2018. These cases include copyright infringement cases, unfair competition cases, and defamation cases, among others. Adverse results in these lawsuits may include awards of damages and may also result in, or even compel, a change in the Company’s business practices, which could result in a loss of revenue or otherwise harm the business of the Company. For many proceedings, the Company is currently unable to estimate the reasonably possible loss or a range of reasonably possible losses as the proceedings are in the early stages, and/or there is a lack of clear or consistent interpretation of laws specific to the industry-specific complaints among different jurisdictions. As a result, there is considerable uncertainty regarding the timing or ultimate resolution of such matters, which includes eventual loss, fine, penalty or business impact, if any, and therefore, an estimate for the reasonably possible loss or a range of reasonably possible losses cannot be made. However, the Company believes that such matters, individually and in the aggregate, when finally resolved, are not reasonably likely to have a material adverse effect on the Company’s consolidated results of operations, financial position and cash flows. With respect to the limited number of proceedings for which the Company was able to estimate the reasonably possible losses or the range of reasonably possible losses, such loss estimates were insignificant. |

| Redeemable Noncontrolling Interests |
In November 2014, iQIYI completed a round of preferred shares financing with US$300 million from the external preferred shareholders. In October 2017, the US$1.2 billion iQIYI 2018 Convertible Notes (Note 12) plus related interest purchased by external investors was converted to iQIYI’s new round preferred shares. As the preferred shares could be redeemed by such shareholders upon the occurrence of certain events that are not solely within the control of iQIYI, these preferred shares are accounted for as redeemable noncontrolling interests. Upon completion of the IPO of iQIYI, all preferred shares of iQIYI held by external preferred shareholders were automatically re-designated andconverted on a one-for-one basis into Class A ordinary shares of iQIYI. In October 2015, Xiaodu issued 250,000,000 preferred shares to certain shareholders for a total consideration of US$250 million. In May 2016, Xiaodu issued an additional 42,105,264 preferred shares to certain other shareholders for a total consideration of US$100 million. As the preferred shares could be redeemed by such shareholders upon the occurrence of certain events that are not solely within the control of Xiaodu, these preferred shares were accounted for as redeemable noncontrolling interests. In August 2017, the Company completed the disposal of Xiaodu to Rajax Holding in exchange for its equity shares. In October, 2018 the Company acquired additional shares of a former equity method investee, resulting in the investee becoming a subsidiary of the Company. The subsidiary had issued 159,820,917 outstanding preferred shares to certain shareholders, which could be redeemed by such shareholders upon the occurrence of certain events that are not solely within the control of the subsidiary. Therefore, these preferred share were accounted for as redeemable noncontrolling interests (Note 3). The Company accounts for the changes in accretion to the redemption value in accordance with ASC Topic 480, Distinguishing Liabilities from Equity. The Company elects to use the effective interest method to account for the changes of redemption value over the period from the date of issuance to the earliest redemption date of the noncontrolling interest. |

| Shareholders' Equity |
Ordinary Shares The authorized share capital consisted of 870,400,000 ordinary shares at a par value of US$0.00005 per share, of which 825,000,000 shares were designated as Class A ordinary shares, 35,400,000 as Class B ordinary shares, and 10,000,000 shares designated as preferred shares. The rights of the holders of Class A and Class B ordinary shares are identical, except with respect to voting and conversion rights. Each share of Class A ordinary shares is entitled to one vote per share and is not convertible into Class B ordinary shares under any circumstances. Each share of Class B ordinary shares is entitled to ten votes per share and is convertible into one Class A ordinary share at any time by the holder thereof. Upon any transfer of Class B ordinary shares by the holder thereof to any person or entity that is not an affiliate of such holder, such Class B ordinary shares would be automatically converted into an equal number of Class A ordinary shares. The number of Class B ordinary shares transferred to Class A ordinary shares was 91,667 shares, 200,000 shares and nil in the years ended December 31, 2016, 2017 and 2018, respectively. As of December 31, 2018, there were 27,733,692 and 7,201,254 Class A and Class B ordinary shares outstanding, respectively. As of December 31, 2017 and 2018, there were no preferred shares issued and outstanding. On July 30, 2015, the Company announced a share repurchase program in which the Company proposed to acquire up to an aggregate of US$1.0 billion of its shares over the next 12 months. On October 29, 2015, the Company announced a share repurchase program under which the Company proposed to acquire up to an aggregate of US$2.0 billion of its shares over the next 24 months. On June 27, 2018, the Company announced a share repurchase program under which the Company proposed to acquire up to an aggregate of US$1.0 billion of its ordinary shares over the next 12 months in the open market or through privately negotiated transactions, depending on market conditions and in accordance with applicable rules and regulations. The Company repurchased nil, 145,783 and 207,165 Class A ordinary shares from the open market with an aggregate purchase price of nil, RMB1.7 billion and RMB3.3 billion (US$482 million) during the years ended December 31, 2016, 2017 and 2018. The repurchased shares were cancelled under Cayman Islands law upon repurchase and the difference between the par value and the repurchase price was debited to retained earnings. Retained Earnings In accordance with the Regulations on Enterprises with Foreign Investment of China and their articles of association, the Company’s PRC subsidiaries, being foreign invested enterprises established in China, are required to make appropriations to certain statutory reserves, namely a general reserve fund, an enterprise expansion fund, a staff welfare fund and a bonus fund, all of which are appropriated from net profit as reported in their PRC statutory accounts. Each of the Company’s PRC subsidiaries is required to allocate at least 10% of its after-tax profits to a general reserve fund until such fund has reached 50% of its respective registered capital. Appropriations to the enterprise expansion fund and staff welfare and bonus funds are at the discretion of the Company’s subsidiaries. In accordance with the China Company Laws, the Company’s VIEs must make appropriations from their after-tax profits as reported in their PRC statutory accounts to non-distributable reserve funds, namely a statutory surplus fund, a statutory public welfare fund and a discretionary surplus fund. Each of the Company’s VIEs is required to allocate at least 10% of its after-tax profits to the statutory surplus fund until such fund has reached 50% of its respective registered capital. Appropriations to the statutory public welfare fund and the discretionary surplus fund are made at the discretion of the Company’s VIEs. General reserve and statutory surplus funds are restricted to set-off against losses, expansion of production and operation and increasing registered capital of the respective company. Staff welfare and bonus fund and statutory public welfare funds are restricted to capital expenditures for the collective welfare of employees. The reserves are not allowed to be transferred to the Company in terms of cash dividends, loans or advances, nor are they allowed for distribution except under liquidation.
Under PRC laws and regulations, there are restrictions on the Company’s PRC subsidiaries and VIEs with respect to transferring certain of their net assets to the Company either in the form of dividends, loans, or advances. Amounts of net assets restricted include paid in capital and statutory reserve funds of the Company’s PRC subsidiaries and the net assets of the VIEs in which the Company has no legal ownership, totaling RMB18.6 billion and RMB25.7 billion (US$3.7 billion) as of December 31, 2017 and 2018, respectively.
Furthermore, cash transfers from the Company’s PRC subsidiaries to their parent companies outside of China are subject to PRC government control of currency conversion. Shortages in the availability of foreign currency may restrict the ability of the PRC subsidiaries and consolidated affiliated entities to remit sufficient foreign currency to pay dividends or other payments to the Company, or otherwise satisfy their foreign currency denominated obligations. Accumulated Other Comprehensive Income (Loss) The changes in accumulated other comprehensive income (loss) by component, net of tax, were as follows:
The amounts reclassified out of accumulated other comprehensive income represent realized foreign currency translation adjustments and gains on the available-for-sale investments upon their sales, which were then recorded in “Other income, net” in the consolidated statements of comprehensive income. The amounts reclassified were determined on the basis of specific identification.
The following table sets forth the tax effect allocated to each component of other comprehensive income (loss) for the years ended December 31, 2016, 2017 and 2018:

| Share-Based Awards Plan |
Baidu, Inc. 2008 Share Incentive plan In December 2008, the Company adopted a share incentive plan (the “2008 Plan”), which provides for the granting of share incentives, including incentive share options (“ISOs”), restricted shares and any other form of award pursuant to the 2008 Plan, to members of the board, employees, consultants and non-employees of the Company. The Company reserved 3,428,777 ordinary shares for issuance under the 2008 Plan, which expired in the year 2018. The vesting schedule, time and condition to exercise options was determined by the compensation committee. The term of the options may not exceed ten years from the date of the grant, except that five years is the maximum term of an ISO granted to an employee who holds more than 10% of the voting power of the Company’s share capital. Under the 2008 Plan, share options are subject to vesting schedules varying from two to four years, the exercise price of an option may be amended or adjusted at the discretion of the compensation committee, the determination of which would be final, binding and conclusive. To the extent not prohibited by applicable laws or exchange rules, a downward adjustment of the exercise prices would be effective without the approval of the Company’s shareholders or the approval of the affected grantees. If the Company grants an ISO to an employee who, at the time of that grant, owns shares representing more than 10% of the voting power of all classes of the Company’s share capital, the exercise price cannot be less than 110% of the fair market value of the Company’s ordinary shares on the date of that grant. 2018 Share Incentive Plan. In July 2018, the Company adopted a share incentive plan (the “2018 Plan”), which provides for the granting of share incentives, including ISOs, restricted shares and any other form of award pursuant to the 2018 Plan, to members of the board, employees, consultants, and non-employees of the Company. The 2018 Plan has a ten-year term and a maximum number of 3,443,950 Class A ordinary shares available for issuance pursuant to all awards under the 2018 Plan. As of December 31, 2018, the Company has not granted any awards under the 2018 Plan. Starting from February 15, 2006, the Company granted restricted Class A ordinary shares of the Company (“Restricted Shares”). Terms for the Restricted Shares are the same as share options except that Restricted Shares do not require exercise and have a two to four years vesting term. Share options The following table summarizes the option activity for the year ended December 31, 2018:
The aggregate intrinsic value in the table above represents the difference between the Company’s closing stock price on the last trading day in 2018 and the exercise price.
Total intrinsic value of options exercised for the years ended December 31, 2016, 2017 and 2018 was RMB143 million, RMB403 million and RMB 474 million (US$69 million), respectively. The total fair value of options vested during the years ended December 31, 2016, 2017 and 2018 was RMB225 million, RMB195 million and RMB 956 million (US$139 million), respectively. As of December 31, 2018, there was RMB337 million (US$49 million) unrecognized share-based compensation cost related to share options, which is expected to be recognized over a weighted-average vesting period of 2.4 years. To the extent the actual forfeiture rate is different from the original estimate, actual share-based compensation costs related to these awards may be different from expectation. The fair value of each option award was estimated on the date of grant using the Black-Scholes-Merton valuation model. The volatility assumption was estimated based on historical volatility of the Company’s share price applying the guidance provided by ASC 718. Assumptions of the expected term were based on the vesting and contractual terms and employee demographics. The risk-free rate for periods within the contractual life of the option is based on the U.S. Treasury yield curve in effect at the time of grant. The following table presents the assumptions used to estimate the fair values of the share options granted in the years presented:
In addition, the Company recognizes share-based compensation expense net of an estimated forfeiture rate and therefore only recognizes compensation cost for those shares expected to vest over the service period of the award. The estimation of the forfeiture rate is primarily based on historical experience of employee turnover. To the extent the Company revises this estimate in the future, the share-based payments could be materially impacted in the year of revision, as well as in the following years. The exercise price of options granted during the years ended December 31, 2016, 2017 and 2018 equaled the market price of the ordinary shares on the grant date. The weighted-average grant-date fair value of options granted during the years ended December 31, 2016, 2017, and 2018 was US$660, US$747, and US$1,029, respectively.
Restricted Shares Restricted Shares activity for the year ended December 31, 2018 was as follows:
The total fair value of the Restricted Shares vested during the years ended December 31, 2016, 2017 and 2018 was RMB1.1 billion, RMB2.1 billion, RMB3.4 billion (US$498 million), respectively. The weighted-average grant-date fair value of the Restricted Shares granted during the years ended December 31, 2016, 2017, and 2018 was US$1,756, US$1,978, and US$2,232, respectively. As of December 31, 2018, there was RMB5.2 billion (US$762 million) unrecognized share-based compensation cost related to Restricted Shares. That deferred cost will be recognized over a weighted-average vesting period of 2.7 years. To the extent the actual forfeiture rate is different from the original estimate, actual share-based compensation costs related to these awards may be different from expectation. Subsidiaries-iQIYI 2010 Equity Incentive Plan In October 2010, iQIYI adopted its 2010 Equity Incentive Plan (the “iQIYI 2010 Plan”), which permits the grant of restricted shares, options and share appreciation rights to the employees, directors, officers and consultants to purchase iQIYI’s ordinary shares. The iQIYI 2010 Plan is valid and effective for a term of ten years commencing from its adoption. Except for service conditions, there were no other vesting conditions for all the awards under the 2010 Plan. As of December 31, 2018, the share option pool under the iQIYI 2010 Plan approved by the Board of Directors of iQIYI was 589,729,714 iQIYI’s ordinary shares. All options granted vest over a four-year period, with 25% of the awards vesting on the first anniversary, and the remaining 75% of the awards vesting on a quarterly basis thereafter.
The following table sets forth the summary of employee option activity under the iQIYI’s 2010 Plan:
As of December 31, 2018, there was RMB1.4 billion (US$207 million) unrecognized share-based compensation cost related to share options granted by iQIYI. That deferred cost is expected to be recognized over a weighted-average vesting period of 3 years. 2017 Share Incentive Plan In November 2017, iQIYI adopted its 2017 Share Incentive Plan (the “iQIYI 2017 Plan”). Under the iQIYI 2017 Plan, iQIYI is authorized to grant options, restricted shares and restricted share units to members of the board, employees, consultants and other individuals for which the maximum aggregate number of ordinary shares which may be issued pursuant to all awards is 720,000 iQIYI’s ordinary shares. The iQIYI 2017 Plan is valid and effective for a term of ten years commencing from its adoption. Except for service conditions, there are no other vesting conditions for all the awards issued under the 2017 Plan. As of December 31, 2018, the unrecognized share-based compensation cost related to its Restricted Shares is insignificant. The following table summarizes the share-based compensation cost recognized by iQIYI:

| Fair Value Measurement |
ASC 820 establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows:
ASC 820 describes three main approaches to measuring the fair value of assets and liabilities: (1) market approach; (2) income approach and (3) cost approach. The market approach uses prices and other relevant information generated from market transactions involving identical or comparable assets or liabilities. The income approach uses valuation techniques to convert future amounts to a single present value amount. The measurement is based on the value indicated by current market expectations about those future amounts. The cost approach is based on the amount that would currently be required to replace an asset.
Assets and Liabilities Measured or Disclosed at Fair Value In accordance with ASC 820, the Company measures available-for-sale investments, other invested securities, investments accounted for at fair value, equity securities with readily determinable fair value and derivatives instruments on a recurring basis. The fair value of time deposits are determined based on the prevailing interest rates in the market. The fair values of the Company’s held-to-maturity investments as disclosed are determined based on the discounted cash flow model using the discount curve of market interest rates. The fair value of the Company’s available-for-sale debt investments and other invested securities are measured using the income approach, based on quoted market interest rates of similar instruments and other significant inputs derived from or corroborated by observable market data. The fair values of the Company’s equity investments in the equity securities of publicly listed companies are measured using quoted market prices. Investments accounted at the fair value and available-for-sale debt investment are primarily investments in private companies, which do not have readily determinable market values. The fair value of these investments were categorized as Level 3 in the fair value hierarchy. The Company uses a combination of valuation methodologies, including market and income approaches based on the Company’s best estimate, which is determined by using information including but not limited to the pricing of recent rounds of financing, future cash flow forecasts, liquidity factors and selection of the comparable companies. The Company measures long-term investments at fair value on a nonrecurring basis, in the cases of an impairment charge is recognized, fair value of an investment is remeasured in an acquisition/a disposal, and an orderly transaction for identical or similar investments of the same issuer was identified for equity investments the Company elected to use the measurement alternative. The Company’s non-financial assets, such as intangible assets, goodwill and fixed assets, would be measured at fair value only if they were determined to be impaired on an other-than-temporary basis. The fair value of notes payable is extracted directly from the quoted market price. The Company classifies the fair value of the convertible senior notes as Level 3 within the fair value hierarchy due to the lack of observable market data and activity. The Company carries the convertible senior notes at face value less unamortized debt discount and issuance costs on its consolidated balance sheet, and presents the fair value for required disclosure purposes only. For further information on the convertible senior notes see Note 12.
Assets and liabilities measured on a recurring basis or disclosed at fair value are summarized below:
Assets measured at fair value on a non-recurring basis The Company measures non-financial assets such as long-term investments on a nonrecurring basis when impairment charges are recognized. These nonrecurring fair value measurements use significant unobservable inputs (Level 3). The Company recognized long-term investment charges of RMB245 million, RMB597 million and RMB622 million (US$90 million) for the years ended December 31, 2016, 2017 and 2018, respectively, due to declining financial performances and changes in business circumstances of these investees. The Company uses a combination of valuation methodologies, including market and income approaches based on the Company’s best estimate to determine the fair value of these investments. For investments in private companies, information considered by the Company include but are not limited to the pricing of recent rounds of financing, future cash flow forecasts, and liquidity factors. Inputs used in these methodologies primarily include future cashflows, discount rate, and the selection of comparable companies operating in similar businesses. For investments in listed companies, the Company mainly considered the quoted share price. |

| Use of Estimates | Use of Estimates The preparation of the financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the period. Management evaluates estimates, including those related to the standalone selling prices of performance obligations of revenue contracts, accounts receivable and contract assets allowances, credit loss allowance for micro loan receivables, fair values of certain debt and equity investments, amortization and impairment of licensed copyrights and produced content, ultimate revenue of produced content, fair value of nonmonetary content exchanges, impairment of long-lived assets, long-term investments and goodwill, the purchase price allocation and fair value of noncontrolling interests with respect to business combinations, deferred tax valuation allowance, and redeemable noncontrolling interests, among others. Management bases the estimates on historical experience and on various other assumptions that are believed to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities. Actual results could differ from these estimates. |

| Foreign Currency | Foreign Currency The Company’s functional currency is the US$. The Company’s subsidiaries, VIEs and subsidiaries of the VIEs determine their functional currencies based on the criteria of ASC Topic 830, Foreign Currency Matters. The Company uses the RMB as its reporting currency. The Company uses the exchange rate as of the balance sheet date to translate its assets and liabilities and the average daily exchange rate for each month to translate its income and expense items to reporting currency. Any translation gains (losses) are recorded in other comprehensive income (loss). Transactions denominated in foreign currencies are measured and recorded into the functional currency at the exchange rates prevailing on the transaction dates. Assets and liabilities denominated in foreign currencies other than functional currency are remeasured into the functional currency at the exchange rates prevailing at the balance sheet date. Exchange gains and losses are included in earnings as a component of “Other income, net.” |

| Segment Reporting | Segment Reporting As of December 31, 2017 and 2018, the Company had two reportable segments, Baidu Core and iQIYI. Baidu Core mainly provides search-based, feed-based, and other online marketing services, as well as new artificial intelligence business. Search Services and Transaction Services were combined into Baidu Core beginning April 2017, to reflect the Company’s strategic and operational change to de-emphasize its transaction services business and shift more resources to support its online marketing and other services. iQIYI is an online entertainment service provider that, offers original, professionally produced and partner-generated content on its platform. In early April 2018, iQIYI completed its initial public offering (“IPO”) on the Nasdaq Global Market. The Company’s chief executive officer, who has been identified as the chief operating decision marker (“CODM”), reviews the operating results of Baidu Core and iQIYI, to allocate resources and assess the Company’s performance. Accordingly, the financial statements include segment information which reflects the current composition of the reportable segments in accordance with ASC Topic 280, Segment Reporting. |

| Business Combinations | Business Combinations The Company accounts for its business combinations using the purchase method of accounting in accordance with ASC Topic 805, Business Combinations. The purchase method of accounting requires that the consideration transferred to be allocated to the assets, including separately identifiable assets and liabilities the Company acquired, based on their estimated fair values. The consideration transferred in an acquisition is measured as the aggregate of the fair values at the date of exchange of the assets given, liabilities incurred, and equity instruments issued as well as the contingent considerations as of the acquisition date. The costs directly attributable to the acquisition are expensed as incurred. Identifiable assets, liabilities and contingent liabilities acquired or assumed are measured separately at their fair value as of the acquisition date, irrespective of the extent of any noncontrolling interests. The excess of (i) the total of cost of acquisition, fair value of the noncontrolling interests and acquisition date fair value of any previously held equity interest in the acquiree over (ii) the fair value of the identifiable net assets of the acquiree, is recorded as goodwill. If the cost of acquisition is less than the fair value of the net assets of the subsidiary acquired, the difference is recognized directly in earnings. In a business combination achieved in stages, the Company remeasures its previously held equity interest in the acquiree immediately before obtaining control at its acquisition-date fair value and the re-measurement gain or loss, if any, is recognized in earnings. The determination and allocation of fair values to the identifiable assets acquired, liabilities assumed and noncontrolling interests is based on various assumptions and valuation methodologies requiring considerable judgment from management. The most significant variables in these valuations are discount rates, terminal values, the number of years on which to base the cash flow projections, as well as the assumptions and estimates used to determine the cash inflows and outflows. The Company determines discount rates to be used based on the risk inherent in the related activity’s current business model and industry comparisons. Terminal values are based on the expected life of assets, and forecasted cash flows over that period. |

| Cash and Cash Equivalents and Restricted Cash | Cash, Cash Equivalents and Restricted Cash Cash and cash equivalents Cash and cash equivalents primarily consist of cash, money market funds, investments in interest bearing demand deposit accounts, time deposits and highly liquid investments with original maturities of three months or less from the date of purchase and are stated at cost which approximates their fair value. Restricted cash Restricted cash mainly consists of the cash reserved in escrow accounts at certain banks as online payment service deposits and cash pledged for bank loan facility. In November 2016, the FASB issued Accounting Standards Update No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash, which requires companies to include amounts generally described as restricted cash and restricted cash equivalents in cash and cash equivalents when reconciling beginning-of-period and end-of-period total amounts presented in the statement of cash flows. The Company adopted the new standard effective January 1, 2018, using the retrospective transition method. All restricted cash was presented on the face of the consolidated balance sheet as “Restricted cash.” |

| Accounts Receivable, net of allowance | Accounts Receivable, net of allowance Accounts receivable are recognized and carried at the original invoiced amount less an allowance for any potential uncollectible amounts. An estimate for doubtful debts is made when collection of the full amount is no longer probable. Receivable balances are written off when they are deemed uncollectible. The Company generally does not require collateral from its customers. The Company maintains allowances for doubtful accounts for estimated losses resulting from the failure of customers to make payments on time. The Company reviews the accounts receivable on a periodic basis and makes general and specific allowances when there is doubt as to the collectability of individual balances. In evaluating the collectability of individual receivable balances, the Company considers many factors, including the age of the balance, the customer’s payment history, its current credit-worthiness and current economic trends. |

| Receivables from Online Payment Agencies, net of allowance | Receivables from Online Payment Agencies, net of allowance Receivables from online payment agencies are funds due from the third-party online payment service providers for clearing transactions. Funds were paid or deposited by customers or users through these online payment agencies for services provided by the Company. The Company carefully considers and monitors the credit worthiness of the third-party payment service providers used. An allowance for doubtful accounts is recorded in the period in which a loss is determined to be probable. Receivable balances are written off when they are deemed uncollectible. The balances are included in “Other current assets, net” on the consolidated balance sheets. As of December 31, 2017 and 2018, no allowance for doubtful accounts was provided for the receivables from online payment agencies. |

| Loan and Interest Receivables, net of allowance | Loan and Interest Receivables, net of allowance Loan and interest receivables consist primarily of micro loans to individual borrowers. Such amounts are recorded at the principal net of allowance for credit losses relating to micro loans, and include accrued interest receivable as of the balance sheet date. The loan periods granted by the Company to the borrowers related to the micro loans generally range from one month to thirty-six months. The cash flows related to micro loans are included within the cash flows from investing activities category in the consolidated statement of cash flows. Allowance for credit losses relating to micro loans represent the Company’s best estimate of the losses inherent in the outstanding portfolio of loans. Judgment is required to determine the allowance amounts and whether such amounts are adequate to cover potential credit losses, and periodic reviews are performed to ensure such amounts continue to reflect the best estimate of the losses inherent in the outstanding portfolio of debts. The Company bases the allowance for loan and interest receivables credit losses primarily on historical loss experience using a roll rate-based model applied to the loan and interest receivables portfolios. The Company considers many factors, including but not limited to, the age of the amounts due, the payment history, the month of origination, the purpose of the loans, creditworthiness, financial conditions of the borrower, terms of the loans, regulatory environment, and the general economic conditions. In August 2018, the Company completed the divestiture of its financial services business, and related loan and interest receivable balances were derecognized from the consolidated balance sheet upon disposal (Note 4). |

| Investments | Investments Short-term investments All highly liquid investments with original maturities of greater than three months, but less than twelve months, are classified as short-term investments. Investments that are expected to be realized in cash during the next twelve months are also included in short-term investments. The Company accounts for short-term debt investments in accordance with ASC Topic 320, Investments—Debt Securities (“ASC 320”). The Company classifies the short-term investments in debt as “held-to-maturity,” “trading” or “available-for-sale,” whose classification determines the respective accounting methods stipulated by ASC 320. Dividend and interest income, including amortization of the premium and discount arising at acquisition, for all categories of investments in securities are included in earnings. Any realized gains or losses on the sale of the short-term investments are determined on a specific identification method, and such gains and losses are reflected in earnings during the period in which gains or losses are realized. Securities that the Company has positive intent and ability to hold to maturity are classified as held-to-maturity securities and stated at amortized cost. For individual securities classified as held-to-maturity securities, the Company evaluates whether a decline in fair value below the amortized cost basis is other-than-temporary in accordance with ASC 320. Other-than-temporary impairment loss is recognized in earnings equal to the entire excess of the debt security’s amortized cost basis over its fair value at the balance sheet date of the reporting period for which the assessment is made. Securities that are bought and held principally for the purpose of selling them in the near term are classified as trading securities, in accordance with ASC 320. Unrealized holding gains and losses for trading securities are included in earnings. Debt investments not classified as trading or as held-to-maturity are classified as available-for-sale debt securities, which are reported at fair value, with unrealized gains and losses recorded in “Accumulated other comprehensive income.” An impairment loss on the available-for-sale debt securities is recognized in the consolidated statements of comprehensive income when the decline in value is determined to be other-than-temporary. Other invested securities Other invested securities represent investments purchased by the Company for its financial services business and are resold to third-party investors. These transactions do not meet the requirements of asset derecognition in accordance with ASC Topic 860, Transfers and Servicing (“ASC 860”). The Company records the proceeds related to these transactions as secured borrowings included in “Amounts due to the third-party investors” on the consolidated balance sheets, and assets pledged are included in “Other invested securities” on the consolidated balance sheets. Other invested securities are issued by financial institutions and have a variable rate of return that is indexed to the performance of underlying assets. The Company initially records these investments at cost, which approximates its fair value at inception and subsequently records these investments at fair value. Changes in the fair value are reflected in earnings. The cash flows related to purchases and maturities of other invested securities are classified as cash flows from investing activities, while proceeds and payments related to the sale and purchase of financial products are classified as cash flows from financing activities in the consolidated statements of cash flows. All other invested securities balances were derecognized from the consolidated balance sheet upon the disposal of the financial services business (Note 4). Long-term investments The Company’s long-term investments consist of equity investments with and equity investments without readily determinable fair value, equity method investments, available-for-sale debt investments and other investments accounted for at fair value. Prior to adopting ASC Topic 321, Investments—Equity Securities (“ASC 321”) on January 1, 2018, the Company carries at cost its investments in investees that do not have readily determinable fair value and over which the Company does not have significant influence, in accordance with ASC Subtopic 325-20, Investments-Other: Cost Method Investments. The Company only adjusts the carrying value of such investments for other-than-temporary decline in fair value and for distribution of earnings that exceed the Company’s share of earnings since its investment. Management regularly evaluates the impairment of the cost method investments based on the performance and financial position of the investee as well as other evidence of market value. Such evaluation includes, but is not limited to, reviewing the investee’s cash position, recent financing, projected and historical financial performance, cash flow forecasts and financing needs. An impairment loss is recognized in earnings equal to the excess of the investment’s cost over its fair value at the balance sheet date of the reporting period for which the assessment is made. The fair value would then become the new cost basis of the investment. Subsequent to the Company’s adoption of ASC 321 on January 1, 2018, the cumulative effect of RMB1.9 billion (US$270 million) representing the unrealized gains and losses of available-for-sale equity securities before the adoption was recorded as an adjustment to the opening retained earnings. Pursuant to ASC 321, equity investments, except for those accounted for under the equity method, those that result in consolidation of the investee and certain other investments, are measured at fair value, and any changes in fair value are recognized in earnings. For equity securities without readily determinable fair value and do not qualify for the existing practical expedient in ASC Topic 820, Fair Value Measurements and Disclosures (“ASC 820”) to estimate fair value using the net asset value per share (or its equivalent) of the investment, the Company elected to use the measurement alternative to measure those investments at cost, less any impairment, plus or minus changes resulting from observable price changes in orderly transactions for identical or similar investments of the same issuer, if any. Equity securities with readily determinable fair value are measured at fair values, and any changes in fair value are recognized in earnings. Pursuant to ASC 321, for equity investments measured at fair value with changes in fair value recorded in earnings, the Company does not assess whether those securities are impaired. For those equity investments that the Company elects to use the measurement alternative, the Company makes a qualitative assessment of whether the investment is impaired at each reporting date. If a qualitative assessment indicates that the investment is impaired, the entity has to estimate the investment’s fair value in accordance with the principles of ASC 820. If the fair value is less than the investment’s carrying value, the entity has to recognize an impairment loss in net income equal to the difference between the carrying value and fair value. Available-for-sale debt investment is convertible debt instrument issued by a private company, which is measured at fair value, with unrealized gain or loss recorded in accumulated other comprehensive income. Investments in entities in which the Company can exercise significant influence but does not own a majority equity interest or control are accounted for using the equity method of accounting in accordance with ASC Topic 323, Investments-Equity Method and Joint Ventures (“ASC 323”). Under the equity method, the Company initially records its investment at cost and the difference between the cost of the equity investee and the fair value of the underlying equity in the net assets of the equity investee is recognized as equity method goodwill, which is included in the equity method investment on the consolidated balance sheets. The Company subsequently adjusts the carrying amount of its investment to recognize the Company’s proportionate share of each equity investee’s net income or loss into earnings. The Company will discontinue applying the equity method if an investment (plus additional financial support provided to the investee, if any) has been reduced to zero. When the Company has other investments in its equity-method investee and is not required to advance additional funds to that investee, the Company would continue to report its share of equity method losses in its statement of comprehensive income after its equity-method investment in ordinary shares has been reduced to zero, to the extent of and as an adjustment to the adjusted basis of the Company’s other investments in the investee. Such losses are first applied to those investments of a lower liquidation preference before being further applied to the investments of a higher liquidation preference. The Company adopted a one-quarter lag in reporting for its share of equity income (loss) in all of its investees. The Company evaluates the equity method investments for impairment whenever events or changes in circumstances indicate that the carrying amount of the investment might not be recoverable. Factors considered by the Company when determining whether an investment has been other-than-temporarily-impaired, includes, but not limited to, the length of the time and the extent to which the market value has been less than cost, the financial performance and near-term prospect of the investee, and the Company’s intent and ability to retain the investment until the recovery of its cost. An impairment loss on the equity method investments is recognized in earnings when the decline in value is determined to be other-than-temporary. In accordance with ASC 946-320 Financial Services—Investment Companies, Investments—Debt and Equity Securities, the Company accounts for long-term equity investments in unlisted companies held by consolidated investment companies at fair value. These investments were initially recorded at their transaction price net of transaction costs, if any. Fair value of these investments are re-measured periodically in accordance with ASC 820. |

| Transfers of Financial Assets | Transfers of Financial Assets The Company accounts for the transfers of financial assets in accordance with ASC 860. Financial assets are derecognized from the Company’s consolidated balance sheets if the transfer qualifies as sales. If the conditions for sale required by ASC 860 are not met, the transfer is considered to be a secured borrowing included in “Amounts due to the third-party investors” on the consolidated balance sheets. The assets remain on the consolidated balance sheets as “Other invested securities” and the sale proceeds are recognized as the Company’s liability. All other invested securities and liability balances were derecognized from the consolidated balance sheet upon disposal of the financial services business (Note 4). |

| Fair Value Measurements of Financial Instruments | Fair Value Measurements of Financial Instruments Financial instruments are in the form of cash and cash equivalents, restricted cash, short-term investments, other invested securities, accounts receivable, loan and interest receivables, amounts due from and due to related parties, other receivables, long-term investments, short-term loans, accounts payable and accrued liabilities, customer advances and deposits, derivative instruments, notes payable, convertible senior notes and long-term loans. The carrying values of the aforementioned financial instruments included in current assets and liabilities approximate their respective fair values because of their general short maturities. The carrying amounts of long-term loans approximate fair values as the related interest rates approximate rates currently offered by financial institutions for similar debt instruments of comparable maturities. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Fixed Assets | Fixed Assets Fixed assets are stated at cost less accumulated depreciation. Depreciation is recorded on a straight-line basis over the shorter of the estimated useful lives of the assets or the term of the related lease, as follows:
Fixed assets have no estimated residual value except for the office building and its related facility, machinery and equipment, which have an estimated residual value of 4% of the cost.
Repair and maintenance costs are charged to expense as incurred, whereas the cost of renewals and betterments that extend the useful life of fixed assets are capitalized as additions to the related assets. Retirements, sales and disposals of assets are recorded by removing the cost and accumulated depreciation from the asset and accumulated depreciation accounts with any resulting gain or loss reflected in earnings. All direct and indirect costs that are related to the construction of fixed assets and incurred before the assets are ready for their intended use are capitalized as construction in progress. Construction in progress is transferred to specific fixed assets items and depreciation of these assets commences when they are ready for their intended use. Interest costs are capitalized if they are incurred during the acquisition, construction or production of a qualifying asset and such costs could have been avoided if expenditures for the assets have not been made. Capitalization of interest costs commences when the activities to prepare the asset are in progress and expenditures and borrowing costs are being incurred. Interest costs are capitalized until the assets are ready for their intended use. Interest costs capitalized for the years ended December 31, 2016, 2017 and 2018 were insignificant.

| Licensed Copyrights | Licensed Copyrights Licensed copyrights consist of professionally-produced content such as movies, television series, variety shows, sports and other video content acquired from external parties. The license fees are capitalized and, unless prepaid, a corresponding liability recorded when cost of the content is known, the content has been accepted by us in accordance with the conditions of the license agreement and the content is available for its first showing on our internet platform. Licensed copyrights are carried at the lower of unamortized cost or net realizable value. The current and non-current portions of licensed copyrights of video content are recorded in “Other current assets, net” or “Intangible assets, net,” respectively. Licensed copyrights include non-exclusive and exclusive content. For non-exclusive licensed copyrights, the Company only has the right to broadcast the content on its internet platform. For exclusive licensed copyrights, in addition to the broadcasting rights, the Company also has the right to sublicense the content to third parties. Non-exclusive licensed copyrights, mainly comprising of newly released movies, television series and seasonal variety shows, are generally amortized using an accelerated method based on historical viewership consumption patterns. Other non-exclusive licensed copyrights, mainly comprising of library movies, television series and variety shows and certain non-episodic features, are amortized on a straight-line basis, as the consumption pattern based on historical viewing data supports this amortization method. Estimates of the consumption patterns for licensed copyrights are reviewed periodically and revised, if necessary. The major factors that impact the viewership consumption patterns include film box office, ratings for television series and variety shows, user traffic on our platforms, placement schedule, user tastes and preferences, emerging cultural trends, merchandising and marketing efforts. Revisions to the amortization pattern are accounted for as a change in accounting estimate prospectively in accordance with ASC Topic 250, Accounting Changes and Error Corrections (“ASC 250”). The purchase cost of exclusive licensed copyrights includes the right to broadcast and the right to sublicense to third parties. The Company allocates content cost to these two rights when the exclusive licensed copyrights are initially recognized, based on the relative proportion of our estimate of the total revenues that will be generated by each right. Content costs related to the broadcasting right, which is the portion of an exclusive licensed copyright that generates direct and indirect advertising and membership revenues, are amortized in accordance with ASC Subtopic 920-350, Entertainment-Broadcasters: Intangibles—Goodwill and Other (“ASC 920-350”), using the same method as non-exclusive licensed copyrights described above. For the right to sublicense to third parties, which is the portion of an exclusive licensed copyright that generates direct revenues, are amortized in accordance with ASC Topic 926, Entertainment—Films (“ASC 926”) using an individual-film-forecast-computation method, which amortizes such costs based on the ratio of the actual sublicensing revenues generated for the current period to the total sublicensing revenues estimated to be generated by the sublicensing right. The Company reviews the forecasted total direct revenues on a periodic basis and any change in estimate will result in a revised fraction applied to the net carrying amount of the right to sublicense. The difference between expenses determined using the new estimates and any amounts previously expensed during the fiscal year is recognized in the period of revision. On a periodic basis, the Company evaluates the program usefulness of the broadcasting rights of its licensed copyrights and record such rights at the lower of unamortized cost or estimated net realizable value pursuant to the guidance in ASC 920-350. When there is a change in the expected usage of licensed copyrights, the Company estimates net realizable value of licensed copyrights to determine if any impairment exists. Net realizable value is determined by estimating the expected cash flows generated from the provision of online advertising and membership services, less any direct costs, over the remaining useful lives of non-exclusive licensedcopyrights. The Company estimates advertising and membership cash flows for each category of content. Estimates that impact advertising and membership cash flows include anticipated levels of demand for the Company’s online advertising and membership services and the expected selling prices of the Company’s advertisements and memberships. For the right to sublicense to third parties, the Company assesses recoverability in accordance with ASC Subtopic 926-20, Entertainment—Films: Other Assets—Film Costs (“ASC 926-20”). The Company recognized impairment charges on licensed copyrights of RMB212 million, RMB390 million and RMB181 million (US$26 million) for the years ended December 31, 2016, 2017 and 2018, respectively. |

| Goodwill and Intangible Assets | Goodwill and Intangible Assets Goodwill The Company assesses goodwill for impairment in accordance with ASC Subtopic 350-20, Intangibles—Goodwill and Other: Goodwill (“ASC 350-20”), which requires that goodwill to be tested for impairment at the reporting unit level at least annually and more frequently upon the occurrence of certain events, as defined by ASC 350-20. As of December 31, 2017 and 2018, the Company has two reporting units, consisting of Baidu Core and iQIYI. The Company has the option to assess qualitative factors first to determine whether it is necessary to perform the two-step test in accordance with ASC 350-20. If the Company believes, as a result of the qualitative assessment, that it is more-likely-than-not that the fair value of the reporting unit is less than its carrying amount, the two-step quantitative impairment test described above is required. Otherwise, no further testing is required. In the qualitative assessment, the Company considers primary factors such as industry and market considerations, overall financial performance of the reporting unit, and other specific information related to the operations. In performing the two-stepquantitative impairment test, the first step compares the carrying amount of the reporting unit to the fair value of the reporting unit based on either quoted market prices of the ordinary shares or estimated fair value using a combination of the income approach and the market approach. If the fair value of the reporting unit exceeds the carrying value of the reporting unit, goodwill is not impaired and the Company is not required to perform further testing. If the carrying value of the reporting unit exceeds the fair value of the reporting unit, then the Company must perform the second step of the impairment test in order to determine the implied fair value of the reporting unit’s goodwill. The fair value of the reporting unit is allocated to its assets and liabilities in a manner similar to a purchase price allocation in order to determine the implied fair value of the reporting unit goodwill. If the carrying amount of the goodwill is greater than its implied fair value, the excess is recognized as an impairment loss.
The Company performed qualitative assessments for the reporting unit of Baidu Core in 2017 and 2018. Based on the requirements of ASC 350-20, the Company evaluated all relevant factors including, but not limited to, macroeconomic conditions, industry and market conditions, financial performance, and the share price of the Company. The Company weighed all factors in their entirety and concluded that it was not more-likely-than-not the fair value was less than the carrying amount of Baidu Core, and further impairment testing on goodwill was unnecessary as of December 31, 2017 and 2018. The Company elected to assess goodwill for impairment using the two-step process for the reporting unit of iQIYI. Subsequent to iQIYI’s IPO, the Company primarily considered the quoted market price of iQIYI’s share to determine the fair value of the reporting unit. Before its IPO, significant management judgment was involved in determining these estimates and assumptions, and actual results may differ from those used in valuations. Changes in these estimates and assumptions could materially affect the determination of fair value for each reporting unit which could trigger future impairment. The judgment in estimating the fair value of a reporting unit includes forecasts of future cash flows, which are based on our best estimate of future revenue and operating expenses growth rates, future capital expenditures and working capital levels, as well as an appropriate discount rate determined by a weighted average cost of capital approach and the selection of comparable companies operating in similar businesses. The Company also reviewed observable market data to assess the reasonableness of assumptions such as discount rate, operating margins, and working capital levels. As of December 31, 2017 and 2018, the fair value of iQIYI exceeded its carrying amount, and therefore goodwill related to the iQIYI reporting unit was not impaired and the Company was not required to perform further testing. Intangible assets Intangible assets with finite lives are carried at cost less accumulated amortization. Land use rights are amortized using a straight-line method over the shorter of their estimated useful lives or the terms of the related land use right contracts. All other intangible assets with finite lives are amortized using the straight-line method over the estimated useful lives, except for the sublicensing rights and certain licensed copyrights. Intangible assets have weighted average useful lives from the date of purchase as follows:
Intangible assets with an indefinite useful life are not amortized and are tested for impairment annually or more frequently if events or changes in circumstances indicate that they might be impaired in accordance with ASC Subtopic 350-30, Intangibles-Goodwill and Other: General Intangibles Other than Goodwill (“ASC 350-30”). |

| Produced Content, net | Produced Content, net The Company produces and contracts external parties to produce films and episodic series to exhibit on its websites. Produced content includes direct production costs, production overhead and acquisition costs and is stated at the lower of unamortized cost or estimated fair value. Produced content also includes cash expenditures made to acquire a proportionate share of certain rights to films including profit sharing, distribution and/or other rights. Produced content exceeding the total revenues to be earned (“ultimate revenue”) is expensed as cost of revenues. The Company uses the individual-film-forecast-computation method and amortizes the produced content based on the ratio of current period actual revenue (numerator) to estimated remaining unrecognized ultimate revenue as of the beginning of the fiscal year (denominator) in accordance with ASC 926-20. The Company reviews the forecasted ultimate revenues on a periodic basis and any change in estimate will result in a revised fraction applied to the net carrying amount of the right to sublicense, and the difference between expenses determined using the new estimates and any amounts previously expensed during the fiscal year is recognized in the period of revision. The Company reviews unamortized produced content costs for impairment whenever events or circumstances indicate that the fair value of the produced content may be less than its unamortized cost. Produced content was presented as “Other non-current assets” on the consolidated balance sheets, the carrying amounts were RMB1.6 billion and RMB3.7 billion (US$543 million), respectively, as of December 31, 2017 and 2018. |

| Impairment of Long-Lived Assets Other Than Goodwill | Impairment of Long-Lived Assets Other Than Goodwill The Company evaluates long-lived assets, such as fixed assets and purchased or internally developed intangible assets with finite lives, for impairment whenever events or changes in circumstances indicate the carrying value of an asset may not be recoverable in accordance with ASC Topic 360, Property, Plant and Equipment. When such events occur, the Company assesses the recoverability of the asset group based on the undiscounted future cash flow the asset group is expected to generate and recognizes an impairment loss when estimated undiscounted future cash flow expected to result from the use of the asset group plus net proceeds expected from disposition of the asset group, if any, is less than the carrying value of the asset group. If the Company identifies an impairment, the Company reduces the carrying amount of the asset group to its estimated fair value based on a discounted cash flow approach or, when available and appropriate, to comparable market values. The Company uses estimates and judgments in its impairment tests and if different estimates or judgments had been utilized, the timing or the amount of any impairment charges could be different. Asset groups to be disposed of would be reported at the lower of the carrying amount or fair value less costs to sell, and no longer depreciated. The assets and liabilities of a disposal group classified as held for sale would be presented separately in the appropriate asset and liability sections of the consolidated balance sheets. |

| Revenue Recognition | Revenue Recognition The Company adopted ASC Topic 606 Revenue from Contracts with Customers (“ASC 606”), from January 1, 2018, using the modified retrospective method. Revenues for the year ended December 31, 2018 were presented under ASC 606, and revenues for the years ended December 31, 2017 and 2016 were not adjusted and continue to be presented under ASC Topic 605, Revenue Recognition. The cumulative effect of adopting ASC 606 resulted in an increase of RMB933 million (US$136 million) to the opening balance of retained earnings at January 1, 2018, which is primarily related to the Company’s online marketing revenues. Revenue is recognized when control of promised goods or services is transferred to the Company’s customers in an amount of consideration to which an entity expects to be entitled to in exchange for those goods or services. Starting from January 1, 2018, value added taxes (“VAT”) was reclassified from cost of revenue to net against revenues in accordance with ASC 606. The Company recognized VAT of RMB3.9 billion, RMB4.8 billion and RMB6.1 billion (US$884 million) for the years ended December 31, 2016, 2017 and 2018, respectively. Other than the presentation of VAT, the impact from adopting ASC 606 was not material to the Company’s consolidated financial statements as of and for the year ended December 31, 2018.
The following table presents the Company’s revenues disaggregated by revenue source:
The Company’s revenue recognition policies effective on the adoption date of ASC 606 are as follows: Performance-based online marketing services Cost-per-click The Company’s auction-based P4P platform enables customers to bid for priority placement of their paid sponsored links. The P4P platform enables customers to reach users who search for information related to their products or services. The P4P services include search-based online marketing services and feed-based online marketing services. The P4P online marketing customers may choose to set a daily limit on the amount spent and may also choose to target only users accessing our website from specified regions in China and/or during a specific time period of the day. Besides the Company’s traditional search-based P4P services, the Company also displays feed-based marketing to target the right feed users based on user data on the Company’s platform. Customers pay the Company when a targeted user clicks the feed-based marketing and are directed to its platforms. Revenue is recognized when all of the revenue recognition criteria are met, which is generally when a user clicks on one of the customer-sponsored links or feed-based marketing. Other performance-based online marketing services To the extent the Company provides online marketing services based on performance criteria other than cost-per-click, such as the number of downloads (and user registration) of mobile apps and the pre-determined ratios of completed transaction volumes, revenue is recognized when the specified performance criteria are met along with the satisfaction of other applicable revenue recognition criteria. Display advertisements The Company provides display-based online advertising services to its customers by integrating text description, image and video, and displaying the advertisement in a prominent position of the search result page, vertical search products or Baidu Feed. The Company recognizes revenue on a pro-rata basis over the contractual term for cost per time advertising arrangements commencing on the date the customer’s advertisement is displayed on the Company’s platform, or based on the number of times that the advertisement has been displayed for cost per thousand impressions advertising arrangements. Online marketing services involving Baidu Union Baidu Union is a program through which the Company expands distribution of its customers’ sponsored links or advertisements by leveraging the traffic of Baidu Union partners’ internet properties. The Company makes payments to Baidu Union partners for the acquisition of traffic. The Company is the principal in these transactions, as it is primarily responsible for fulfilling the service, has discretion in establishing pricing and controls the advertising inventory before the transfer to customers. Therefore, revenue is recognized on a gross basis on the amount of fees it billed to its customers. Payments made to Baidu Union partners are recorded as traffic acquisition costs, which are included in “Cost of revenues” in the consolidated statements of comprehensive income. Membership services The Company offers membership services that provide subscribing members access to stream a library of premium content or personal cloud service in exchange for upfront non-refundable membership fees. When the receipt of membership fees is for services to be delivered over a period of time, the receipt is initially recorded as deferred revenue and revenue is recognized ratably over the membership period as services are rendered. Membership services revenue also includes fees earned from on-demand content purchases made by members and the sale of the right to services such as other memberships, which the Company acquires and controls before they are transferred to the customers. Content distribution The Company generates revenues from sub-licensing content licensed from third party vendors for cash and through nonmonetary exchanges mainly with other online video broadcasting companies. The exclusive licensing agreements the Company enters into with vendors has a definitive license period and provides the Company the rights to sub-license these contents to other third parties. The Company enters into a non-exclusive sub-licenseagreement with a sub-licensee for a period that falls within the original exclusive license period. For cash sub-licensing transactions, the Company receives the sub-license fee upfront under the sub-licensing arrangements and does not have any future obligation once it has provided the underlying content to the sub-licensee (which is provided at or before the beginning of the sub-license period). The sub-license fees are recognized in accordance with ASC 606 and represents a license of functional intellectual property that grants a right to use the Company’s licensed copyrights, and recognized at the point in time when the licensed copyright is made available for the customer’s use and benefit. The Company also enters into nonmonetary transactions to exchange online broadcasting rights of licensed copyrights with other online video broadcasting companies from time to time. The exchanged licensed copyrights provide rights for each party to broadcast the licensed copyrights received on its own website only. Each transferring party retains the right to continue broadcasting the exclusive content on its own website and/or sublicense the rights to the content it surrendered in the exchange. The Company accounts for these nonmonetary exchanges in accordance with ASC 606, and records the transaction based on the fair value of the asset received starting from January 1, 2018. Barter sublicensing revenue are recognized in accordance with the same ASC 606 criteria above. The Company estimates the fair value of the licensed copyrights received based on various factors, including broadcasting schedule, cast and crew, theme and popularity, box office and market share of counterparties to the exchange. The attributable cost of cash sublicensing transactions, whether for cash or through nonmonetary exchanges, is recognized as cost of revenues through the amortization of the sublicensing right component of the exclusive licensed copyright, computed using the individual-film-forecast-computation method in accordance with ASC 926. The Company recognized barter sublicensing revenues of RMB382 million, RMB763 million and RMB1.1 billion (US$158 million) and related costs of RMB363 million, RMB650 million and RMB1.0 billion (US$149 million) for the years ended December 31, 2016, 2017 and 2018, respectively. Barter transactions The Company engages in certain barter transactions other than licensed copyrights of video contents, such as advertising, from time to time. The transaction price of the nonmonetary consideration is measured at fair value at contract inception. If fair value cannot be reasonably estimated, the Company measures the consideration indirectly by reference to the standalone selling price of the services promised to the customer in exchange for the consideration. Revenues recognized on advertising barter transactions were immaterial for the years ended December 31, 2016, 2017 and 2018. Financial services The Company offers financial services which include provision of installment payment services to consumers and wealth management services to third-party investors. Interest income earned from provision of financial services is reported as “Other revenues” and reported on a net basis after deduction of related interest costs incurred. The Company recognized gross interest income of RMB3.5 billion and RMB3.3 billion (US$483 million) and interest costs of RMB1.9 billion and RMB1.6 billion (US$232 million) for the years ended December 31, 2017 and 2018, respectively. Gross interest income and interest costs recognized for the year ended December 31, 2016 were insignificant. The financial services business was disposed of in August 2018 (Note 4). Other revenue recognition related policies For arrangements that include multiple performance obligations, primarily for advertisements to be displayed in different spots, placed under different forms and displayed at different times, the Company would evaluate all the performance obligations in the arrangement to determine whether each performance obligation is distinct. Consideration is allocated to each performance obligation based on its standalone selling price. If a promised good or service does not meet the criteria to be considered distinct, it is combined with other promised goods or services until a distinct bundle of goods or services exists. Timing of revenue recognition may differ from the timing of invoicing to customers. For certain services customers are required to pay before the services are delivered to the customer. When either party to a revenue contract has performed, the Company recognizes a contract asset or a contract liability in the consolidated balance sheet, depending on the relationship between the entity’s performance and the customer’s payment. Contract liabilities were mainly related to fees for membership services to be provided over the membership period, which were presented as deferred revenue on the consolidated balance sheets. The increase in deferred revenue as compared to the year ended December 31, 2017 is a result of the increase in consideration received from the Company’s customers. The opening balance of contract assets were RMB832 million as of January 1, 2018. As of December 31, 2018, contract assets of RMB1.4 billion (US$206 million), net of allowance for doubtful accounts of RMB21 million (US$3 million) were recognized and included in “Other current assets, net” on the consolidated balance sheet.
The Company does not disclose the value of unsatisfied performance obligations for (i) contracts with an original expected length of one year or less and (ii) contracts for which the Company recognizes revenue at the amount to which it has the right to invoice for services performed. The Company provides sales incentives to customers which entitle them to receive reductions in the price of the online marketing services by meeting certain cumulative consumption requirements. The Company accounts for these incentives granted to customers as variable consideration and net against revenue. The amount of variable consideration is measured based on the most likely amount of incentives to be provided to customers. |

| Cost of Revenues | Cost of Revenues Cost of revenues consists primarily of traffic acquisition costs, bandwidth costs, depreciation, content costs, payroll and related costs of operations. Starting from January 1, 2018, VAT was recorded net against revenue instead of as cost of revenue. Traffic acquisition costs represent the amounts paid or payable to Baidu Union partners who direct search queries to the Company’s websites or distribute the Company’s customers’ paid links through their properties. These payments are primarily based on revenue sharing arrangements under which the Company pays its Baidu Union partners and other business partners a percentage of the fees it earns from its online marketing customers. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Advertising and Promotional Expenses | Advertising and Promotional Expenses Advertising and promotional expenses, including advertisements through various forms of media and kinds of marketing and promotional activities, are included in “Selling, general and administrative expense” in the consolidated statements of comprehensive income (loss) and are expensed when incurred. Advertising and promotional expenses for the years ended December 31, 2016, 2017 and 2018 were RMB7.7 billion, RMB4.6 billion and RMB10.1 billion (US$1.5 billion), respectively. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Government Subsidies | Government Subsidies Government subsidies primarily consist of financial subsidies received from provincial and local governments for operating a business in their jurisdictions and compliance with specific policies promoted by the local governments. For certain government subsidies, there are no defined rules and regulations to govern the criteria necessary for companies to receive such benefits, and the amount of financial subsidy is determined at the discretion of the relevant government authorities. The government subsidies of non-operating nature with no further conditions to be met are recorded as non-operating income in “Other income, net” when received. The government subsidies with certain operating conditions are recorded as “deferred income” when received and will be recorded as operating income when the conditions are met. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Leases | Leases Leases are classified as either capital or operating leases. Leases that transfer substantially all the benefits and risks incidental to the ownership of assets are accounted for as capital leases as if there was an acquisition of an asset and incurrence of an obligation at the inception of the lease. All other leases are accounted for as operating leases wherein rental payments are expensed as incurred. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Income Taxes | Income Taxes The Company recognizes income taxes under the liability method. Deferred income taxes are recognized for differences between the financial reporting and tax bases of assets and liabilities at enacted tax rates in effect for the years in which the differences are expected to reverse. The Company records a valuation allowance against the amount of deferred tax assets that it determines is not more-likely-than-not to be realized. The effect on deferred taxes of a change in tax rates is recognized in earnings in the period that includes the enactment date. The Company applies the provisions of ASC Topic 740, Income Taxes (“ASC 740”), in accounting for uncertainty in income taxes. ASC 740 clarified the accounting for uncertainty in income taxes by prescribing the recognition threshold a tax position is required to meet before being recognized in the financial statements. The Company has elected to classify interest and penalties related to an uncertain tax position (if and when required) as part of income tax expense in the consolidated statements of comprehensive income. As of and for the years ended December 31, 2016, 2017 and 2018, the amounts of unrecognized tax benefits as well as interest and penalties associated with uncertainty in income taxes were insignificant. |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Share-based Compensation | Share-based Compensation The Company accounts for share-based compensation in accordance with ASC Topic 718, Compensation-Stock Compensation (“ASC 718”). The Company has elected to recognize share-based compensation using the straight-line method for all share-based awards issued with no performance conditions. For awards with performance conditions, compensation cost is recognized on an accelerated basis if it is probable that the performance condition will be achieved. Forfeitures are estimated based on historical experience and are periodically reviewed. Cancellation of an award accompanied by the concurrent grant of a replacement award is accounted for as a modification of the terms of the cancelled award (“modified awards”). The compensation costs associated with the modified awards are recognized if either the original vesting condition or the new vesting condition is achieved. Total recognized compensation cost for the awards is at least equal to the fair value of the awards at the grant date unless at the date of the modification the performance or service conditions of the original awards are not expected to be satisfied. The incremental compensation cost is measured as the excess of the fair value of the replacement award over the fair value of the cancelled award at the cancellation date. Therefore, in relation to the modified awards, the Company recognizes share-based compensation over the vesting periods of the replacement award, which comprises, (i) the amortization of the incremental portion of share-based compensation over the remaining vesting term and (ii) any unrecognized compensation cost of the original award, using either the original term or the new term, whichever results in higher expenses for each reporting period. The Company accounts for share awards issued to non-employees in accordance with the provisions of ASC Subtopic 505-50, Equity: Equity-based Payments to Non-Employees. The Company uses the Black-Scholes-Merton option pricing model method to measure the value of options granted to non-employees at each vesting date to determine the appropriate charge to share-based compensation. ASC 718 requires share-based compensation to be presented in the same manner as cash compensation rather than as a separate line item. |

| Earnings Per Share ("EPS") | Earnings Per Share (“EPS”) The Company computes earnings per Class A and Class B ordinary shares in accordance with ASC Topic 260, Earnings Per Share (“ASC 260”), using the two-class method. Under the provisions of ASC 260, basic earnings per share is computed using the weighted average number of ordinary shares outstanding during the period except that it does not include unvested ordinary shares subject to repurchase or cancellation. The Company adjusts for the accretion of the redeemable noncontrolling interests in the calculation of income available to ordinary shareholders of the Company used in the earnings per share calculation. Diluted earnings per share is computed using the weighted average number of ordinary shares and, if dilutive, potential ordinary shares outstanding during the period. Potentially dilutive securities such as convertible senior notes have been excluded from the computation of diluted net income per share if their inclusion is anti-dilutive. Potential ordinary shares consist of the incremental ordinary shares issuable upon the exercise of stock options, restricted shares subject to forfeiture, and contracts that may be settled in the Company’s stock or cash. The dilutive effect of outstanding stock options and restricted shares is reflected in diluted earnings per share by application of the treasury stock method. The computation of the diluted earnings per Class A ordinary share assumes the conversion of Class B ordinary shares to Class A ordinary shares, while diluted earnings per Class B ordinary share does not assume the conversion of such shares. The liquidation and dividend rights of the holders of the Company’s Class A and Class B ordinary shares are identical, except with respect to voting rights. As a result, and in accordance with ASC 260, the undistributed earnings for each year are allocated based on the contractual participation rights of the Class A and Class B ordinary shares as if the earnings for the year had been distributed. As the liquidation and dividend rights are identical, the undistributed earnings are allocated on a proportionate basis. Further, as the conversion of Class B ordinary shares is assumed in the computation of the diluted earnings per Class A ordinary share, the undistributed earnings are equal to net income for that computation. For the purposes of calculating the Company’s basic and diluted earnings per Class A and Class B ordinary shares, the ordinary shares relating to the options that were exercised are assumed to have been outstanding from the date of exercise of such options. |

| Contingencies | Contingencies The Company records accruals for certain of its outstanding legal proceedings or claims when it is probable that a liability will be incurred and the amount of loss can be reasonably estimated. The Company evaluates, on a quarterly basis, developments in legal proceedings or claims that could affect the amount of any accrual, as well as any developments that would make a loss contingency both probable and reasonably estimable. The Company discloses the amount of the accrual if it is material. When a loss contingency is not both probable and estimable, the Company does not record an accrued liability but discloses the nature and the amount of the claim, if material. However, if the loss (or an additional loss in excess of the accrual) is at least reasonably possible, then the Company discloses an estimate of the loss or range of loss, unless it is immaterial or an estimate cannot be made. The assessment of whether a loss is probable or reasonably possible, and whether the loss or a range of loss is estimable, often involves complex judgments about future events. Management is often unable to estimate the loss or a range of loss, particularly where (i) the damages sought are indeterminate, (ii) the proceedings are in the early stages, or (iii) there is a lack of clear or consistent interpretation of laws specific to the industry-specific complaints among different jurisdictions. In such cases, there is considerable uncertainty regarding the timing or ultimate resolution of such matters, including eventual loss, fine, penalty or business impact, if any.

| Concentration of Risks | Concentration of Risks Concentration of credit risk Financial instruments that potentially subject the Company to significant concentration of credit risk primarily consist of cash and cash equivalents, restricted cash, short-term investments, accounts receivable, and amounts due from related parties. As of December 31, 2018, the Company has RMB141.5 billion (US$20.6 billion) in cash and cash equivalents, restricted cash, and short-term investments, 94% and 6% of which are held by financial institutions in the PRC and international financial institutions outside of the PRC, respectively. The Company’s total cash and cash equivalents, restricted cash, and short-term investments held at four financial institutions in the PRC exceeded 10%, representing 37%, 15%, 13%, and 11% of the Company’s total cash and cash equivalents, restricted cash, and short-term investments as of December 31, 2018, respectively. PRC state-owned banks, such as Bank of China, are subject to a series of risk control regulatory standards, and PRC bank regulatory authorities are empowered to take over the operation and management when any of those banks faces a material credit crisis. The Company does not foresee substantial credit risk with respect to cash and cash equivalents, restricted cash and short-term investments held at the PRC state-owned banks. Meanwhile, China does not have an official deposit insurance program, nor does it have an agency similar to what was the Federal Deposit Insurance Corporation (FDIC) in the U.S. In the event of bankruptcy of one of the financial institutions in which the Company has deposits or investments, it may be unlikely to claim its deposits or investments back in full. The Company selected reputable international financial institutions with high rating rates to place its foreign currencies. The Company regularly monitors the rating of the international financial institutions to avoid any potential defaults. There has been no recent history of default in relation to these financial institutions. Accounts receivable are typically unsecured and derived from revenue earned from customers and agents in China, which are exposed to credit risk. The risk is mitigated by credit evaluations the Company performs on its customers and its ongoing monitoring process of outstanding balances. The Company maintains reserves for estimated credit losses and these losses have generally been within its expectations. As of December 31, 2017 and 2018, the Company had no single customer with a receivable balance exceeding 10% of the total accounts receivable balance. No customer or any Baidu Union partner generated greater than 10% of total revenues in any of the three years presented. Amounts due from related parties are typically unsecured. In evaluating the collectability of the amounts due from related parties balance, the Company considers many factors, including the related parties’ repayment history and their credit-worthiness. An allowance for doubtful accounts is made when collection of the full amount is no longer probable. Business and economic risks The Company participates in a dynamic high technology industry and believes that changes in any of the following areas could have a material adverse effect on the Company’s future financial position, results of operations or cash flows: changes in the overall demand for services and products; changes in business offerings; competitive pressures due to new entrants; advances and new trends in new technologies and industry standards; changes in bandwidth suppliers; changes in certain strategic relationships or customer relationships; regulatory considerations; copyright regulations; brand maintenance and enhancement; and risks associated with the Company’s ability to attract and retain employees necessary to support its growth. The Company’s operations could be adversely affected by significant political, economic and social uncertainties in the PRC. Currency convertibility risk Substantially all of the Company’s businesses are transacted in RMB, which is not freely convertible into foreign currencies. All foreign exchange transactions take place either through Bank of China or other banks authorized to buy and sell foreign currencies at the exchange rates quoted by the People’s Bank of China. Approval of foreign currency payments by the People’s Bank of China or other regulatory institutions requires submitting a payment application form together with suppliers’ invoices, shipping documents and signed contracts.
Foreign currency exchange rate risk The functional currency and the reporting currency of the Company are the US$ and the RMB, respectively. The Company’s exposure to foreign currency exchange rate risk primarily relates to cash and cash equivalents, restricted cash, short-term investments, long-term investments, notes payable and convertible senior notes denominated in the US$. On June 19, 2010, the People’s Bank of China announced the end of the RMB’s de facto peg to the US$, a policy which was instituted in late 2008 in the face of the global financial crisis, to further reform the RMB exchange rate regime and to enhance the RMB’s exchange rate flexibility. On March 15, 2014, the People’s Bank of China announced the widening of the daily trading band for RMB against US$. The appreciation of the US$ against the RMB was approximately 5.67% in 2018. Most of the revenues and costs of the Company are denominated in RMB, while a portion of cash and cash equivalents, restricted cash, short-term investments, long-term investments, notes payable and convertible senior notes are denominated in U.S. dollars. It is difficult to predict how market forces or PRC or U.S. government policy may impact the exchange rate between the Renminbi and the U.S. dollar in the future. Any significant fluctuation of the valuation of RMB may materially affect the Company’s cash flows, revenues, earnings and financial position, and the value of, and any dividends payable on, the ADS in US$. |

| Derivative Instruments | Derivative Instruments ASC Topic 815, Derivatives and Hedging (“ASC 815”), requires all contracts which meet the definition of a derivative to be recognized on the balance sheet as either assets or liabilities and recorded at fair value. Changes in the fair value of derivative financial instruments are either recognized periodically in earnings or in other comprehensive income depending on the use of the derivative and whether it qualifies for hedge accounting. Changes in fair values of derivatives not qualified as hedges are reported in earnings. |

| Recent Accounting Pronouncements | Recent Accounting Pronouncements In February 2016, the FASB issued ASU No. 2016-02, Leases (“ASU 2016-02”). ASU 2016-02 specifies the accounting for leases. For operating leases, ASU 2016-02 requires a lessee to recognize a right-of-use asset and a lease liability, initially measured at the present value of the lease payments, in its balance sheet. The standard also requires a lessee to recognize a single lease cost, calculated so that the cost of the lease is allocated over the lease term, on a generally straight-line basis. ASU 2016-02 is effective for public business entities for annual reporting periods and interim periods within those years beginning after December 15, 2018. The Company will adopt ASU 2016-02 on January 1, 2019 using by modified retrospective method and will not restate comparable periods. The Company will elect the package of practical expedients permitted under the transition guidance, which allow the Company to carry forward the historical lease classification, the assessment whether a contract is or contains a lease and initial direct costs for any leases that exist prior to adoption of the new standard. The Company will also elect the practical expedient not to separate lease and non-lease components for certain classes of underlying assets and the short-term lease exemption for contracts with lease terms of 12 months or less. Operating leases related to land use right, offices and internet data center (“IDC”) facilities will be subject to ASU 2016-02 and right-of-use assets and operating lease liabilities will be recognized on the Company’s consolidated balance sheet. The Company currently believes the most significant change will be related to the recognition of right-of-use assets and lease liabilities on the Company’s balance sheet for certain in-scope operating leases. The Company does not expect any material impact on net assets and the consolidated statement of comprehensive income as a result of adopting the new standard. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”) which requires the measurement and recognition of expected credit losses for financial assets held at amortized cost. ASU 2016-13 replaces the existing incurred loss impairment model with an expected loss methodology, which will result in more timely recognition of credit losses. ASU 2016-13 is effective for annual reporting periods, and interim periods within those years, beginning after December 15, 2019. The Company is currently in the process of evaluating the impact of the adoption of ASU 2016-13 on its consolidated financial statements. In June 2018, the FASB issued ASU No. 2018-07, Compensation—Stock Compensation (Topic 718)：Improvements to Nonemployee Share-Based Payment Accounting to simplify the accounting for share-based payments to nonemployees (“ASU 2018-07”) by aligning it with the accounting for share-based payments to employees, with certain exceptions. Under the guidance, the measurement of equity-classified nonemployee awards will be fixed at the grant date, which may lower their cost and reduce volatility in the income statement. The guidance is effective for public business entities in annual periods beginning after December 15, 2018, and interim periods within those years. Early adoption is permitted, including in an interim period. The ASU 2018-07 will impact the accounting of the share-based awards granted to non-employees and the Company does not expect a significant impact on its consolidated financial statements. In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement (“ASU 2018-13”) which eliminates, adds and modifies certain disclosure requirements for fair value measurements. Under the guidance, public companies will be required to disclose the range and weighted average used to develop significant unobservable inputs for Level 3 fair value measurements. The guidance is effective for all entities for fiscal years beginning after December 15, 2019 and for interim periods within those fiscal years, but entities are permitted to early adopt either the entire standard or only the provisions that eliminate or modify the requirements. The Company does not expect a significant impact on its consolidated financial statements. In March 2019, the FASB issued ASU 2019-02, Improvements to Accounting for Costs of Films and License Agreements for Program Materials (“ASU 2019-02”) which improves GAAP by aligning the accounting for production costs of an episodic television series with the accounting for production costs of films by removing the content distinction for capitalization. In addition, ASU 2019-02 requires that an entity test a film or license agreement for program material within the scope of ASC 920-350 for impairment at a film group level when the film or license agreement is predominantly monetized with other films and/or license agreements. The presentation and disclosure requirements in ASU 2019-02 also increase the transparency of information provided to users of financial statements about produced and licensed content. This update will be effective for the Company’s fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. Early adoption is permitted. The Company is currently in the process of evaluating the effect that the adoption of ASU 2019-02 will have on the consolidated financial statements and related disclosures. |
