allowances when there is doubt as to the collectability of individual balances. In evaluating the collectability of individual receivable balances, we consider many factors, including the age of
the balance, the customers payment history, its current credit-worthiness and current economic trends.
Loan and Interest
Receivables, net of Allowance
Loan and interest receivables consist primarily of micro loans to individual
borrowers. Loan 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 us to the borrowers relating to the
micro loans generally range from 1 to 36 months. The cash flows related to micro loans are included in the cash flows from investing activities category in the consolidated statement of cash flows.
Allowance for credit losses relating to micro loans represents our 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 loans. We consider many factors in assessing the collectability of the loan receivables, including but not limited to, the age of the amounts due, payment history and, creditworthiness of the
borrower, financial conditions of the customer, purposes and terms of the loans and the economic conditions to determine the allowance of credit loss.
Impairment of Long-Lived Assets Other Than Goodwill
We evaluate 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, or ASC 360, Property, Plant and Equipment.
When such events occur, we assess the recoverability of the assets group based on the undiscounted future cash flow the assets
group is expected to generate and recognize an impairment loss when estimated undiscounted future cash flow expected to result from the use of the assets group plus net proceeds expected from disposition of the assets group, if any, is less than the
carrying value of the assets group. If we identify an impairment, we reduce the carrying amount of the assets group to its estimated fair value based on a discounted cash flow approach or, when available and appropriate, to comparable market values.
We use estimates and judgments in our 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 sheet. The impairment charges of long-lived assets are RMB1.6 million, nil and RMB1.0 million (US$0.1 million) for 2014, 2015 and 2016, respectively.
Impairment of Goodwill
We assess goodwill for impairment in accordance with ASC subtopic 350-20, or ASC 350-20, IntangiblesGoodwill and Other: Goodwill, 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, 2015 and
December 31, 2016, we had three reporting units, consisting of search services, transaction services and iQiyi. The goodwill was reassigned to the reporting units affected using a relative fair value allocation approach.
We have 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 we believe, 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
