impairment is deemed to have occurred. In these instances, the other-than-temporary impairment loss is recognized in earnings equal to the entire excess of the debt securitys amortized cost
basis over its fair value at the balance sheet date of the reporting period for which the assessment is made. When we do not intend to sell an impaired debt security and it is more-likely-than-not that it will
not be required to sell prior to recovery of its amortized cost basis, we must determine whether or not it will recover its amortized cost basis. If we conclude that it will not, an other-than-temporary impairment exists and that portion of the
credit loss is recognized in earnings, while the portion of loss related to all other factors is recognized in other comprehensive income.
As available-for-sale investment is reported
at fair value, an impairment loss on the long-term available-for-sale securities would be recognized in the consolidated statements of comprehensive income when the
decline in value is determined to be other-than-temporary.
The fair value determination, particularly for investments in
privately-held companies, requires significant judgment to determine appropriate estimates and assumptions. Changes in these estimates and assumptions could affect the calculation of the fair value of the investments and the determination of whether
any identified impairment is other-than-temporary. If impairment is considered other-than-temporary, we will write down the asset to its fair value and take the corresponding charge to the consolidated financial statements. The impairment charges of
long-term investments are RMB93.4 million, RMB117.0 million and RMB245.3 million (US$35.3 million) for 2014, 2015 and 2016, respectively.
Transfers of Financial Assets
We account for transfers of financial assets in accordance with ASC Topic 860, or ASC 860, Transfers and Servicing. For
a transfer of financial assets to be considered as a sale, the assets would be removed from our consolidated balance sheets. If the conditions for sale required by ASC 860 are not met, the transfer is considered to be a secured borrowing, the assets
remain on the consolidated balance sheets and the sale proceeds are recognized as our liability.
Pursuant to ASC 860, the
transactions of Baidu Wealth Management do not constitute a sale of the underlying securities for accounting purposes. We account for these transactions as secured borrowings included in Accounts payable and accrued liabilities on the
consolidated balance sheets, and assets pledged are accounted for as trading securities included in short term investments on the consolidated balance sheets. The cash flows related to purchases and maturities of trading securities investments are
included in the cash flows from investing activities category, and the proceeds and payments related to the sale of financial products are included in the cash flow from financing activities in the consolidated statement of cash flows.
We account for business combinations using the purchase method of accounting in accordance with ASC topic 805, or ASC 805,
Business Combinations. The purchase method accounting requires that the consideration transferred to be allocated to the assets, including separately identifiable assets and liabilities we 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 and all contractual
contingencies 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.
