| Organization, Consolidation and Presentation of Financial Statements | 1. 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. As of December 31, 2017, 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, 2017, the Company also effectively controls a number of variable interest entities (“VIEs”) through the Primary Beneficiaries, as defined below. The VIEs include:
The Company, its subsidiaries, VIEs and subsidiaries of the VIEs are hereinafter collectively referred to as the “Group”. The Group offers online marketing services, artificial intelligence-enabled new business initiatives, internet financial businesses and operates an online video platform offering advertising business and membership services through its content library. 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 Group through loans extended to the authorized individuals who were the shareholders of the VIEs. The Group has 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 Group’s 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 wholly-owned subsidiaries in the PRC, which obligate the Primary Beneficiaries to absorb losses 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 Group has entered into certain agreements with the shareholders of the VIEs through the Primary Beneficiaries or their wholly-owned subsidiaries in the PRC, including loan agreements for the paid-in capital of the VIEs and share pledge agreements for the equity interests in the VIEs held by the shareholders of the VIEs. Despite the lack of technical 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 wholly-owned 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 SEC Regulation S-X Rule 3A-02 and Accounting Standards Codification (“ASC”) topic 810, Consolidation, because the Company holds all the variable interests of the VIEs through the Primary Beneficiaries. 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 are further described below. Loan Agreements Pursuant to loan agreements amongst the shareholders of Baidu Netcom and Baidu Online, Baidu Online provided interest-free loans with an aggregate amount of RMB2.2 billion (US$334 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 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 January 17, 2027 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 and the respective shareholders of Beijing Perusal and BaiduPay contains substantially the same terms as those described above, except that the amount of the loans extended to the respective shareholders is RMB3.2 billion (US$491 million) and RMB217 million (US$33 million), respectively. The term of the loan agreements will expire on June 19, 2026 and October 17, 2026, respectively, 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 from Baidu Netcom to its shareholders should be paid 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.

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, Beijing Perusal and their shareholders, BaiduPay 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 BaiduPay 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 to Baidu Netcom technology consulting and services related to, among other things, the maintenance of servers, software development, design of advertisements, and e-commerce technical services. 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 and Beijing Perusal and between Baidu Online and BaiduPay contains substantially the same terms as those described above. 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 both Beijing Perusal and BaiduPay. Each of the license agreements between Baidu Online and Beijing Perusal and between Baidu Online and BaiduPay contains substantially the same terms as those described above. Each of the web layout copyright license agreements was renewed since 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. 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 and the respective shareholders of Beijing Perusal and BaiduPay contains substantially the same terms, including term period, as those described above. The equity pledges of Baidu Netcom described above are in the process of perfecting by registration with the relevant local administration for industry and commerce as required for a property right under the PRC Property Rights Law, due to recent change in shareholder. 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 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 by Primary Beneficiaries besides Baidu Online with their VIEs and the respective shareholders, which resulted in a parent-subsidiary relationship between the Company and these VIEs. 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, 2017, there was no pledge or collateralization of the VIEs’ assets other than the aforementioned equity pledge agreements. The amount of the net assets of the VIEs was RMB5.1 billion (US$780 million) as of December 31, 2017. 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 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 accounts receivable allowances, credit loss allowance for micro loan receivables, fair values of options to purchase the Company’s or its subsidiaries’ ordinary shares, fair values of certain debt and equity investments, amortization and impairment of licensed copyrights, 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 and acquisition of equity method investees, 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. Comparative Information Certain items in the consolidated financial statements have been adjusted to conform with the current year’s presentation to facilitate comparison. 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 RMB6.5063 per US$1.00 on December 29, 2017, the last business day in fiscal year 2017, 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 | 2. 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 to translate its each month for income and expense items. Any translation gains (losses) are recorded in other comprehensive income (loss). Transactions denominated in foreign currencies are translated into the functional currency at the exchange rates prevailing on the transaction dates. Assets and liabilities denominated in foreign currencies are translated 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 The Company historically had only one single reportable segment because the Company’s chief operating decision maker (“CODM”) formerly relied on the consolidated results of operations when making decisions on allocating resources and assessing performance of the Company. Starting from the quarter ended June 30, 2015, the Company reorganized its operation into three segments, consisting of the Search Services, Transaction Services and iQIYI as a result of its expansion of offerings into multiple services. Starting from April 2017, Search Services and Transaction Services were combined into one segment, namely, Baidu Core. The change in reportable segments reflects the Company’s strategic shift and the operational change to de-emphasized its transaction services business and shifted such resources to support its online marketing services. As of December 31, 2017, the Company had two reportable segments, Baidu Core and iQIYI. Baidu Core mainly provides keyword-based marketing services targeted at and triggered by internet users’ search queries, which mainly include pay-for-performance (“P4P”) services and other online marketing services, artificial intelligence-enabled new business initiatives and internet financial services. iQIYI is an online entertainment service provider that, offers original, professionally produced and partner-generated content on its platform. The Company’s chief executive officer, who has been identified as the CODM, now reviews the operating results of Baidu Core and iQIYI in order 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 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. 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, forecasted life cycle and forecasted cash flows over that period. Cash and Cash Equivalents 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 for the remaining payments in relation to compensation for post-combination services, and the cash balances deposited at certain banks as online payment service deposits. 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. Bad debts are written off as incurred. 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 cash due from the third-party online payment service providers for clearing transactions. The cash was 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 after all collection efforts have been exhausted. The balances are included in “Other current assets, net” on the consolidated balance sheets. As of December 31, 2016 and 2017, 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. 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 investments in accordance with ASC topic 320 (“ASC 320”), Investments – Debt and Equity Securities. The Company classifies the short-term investments in debt and equity securities as “held-to-maturity” 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. The securities that the Company has the positive intent and the 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 the Company’s policy and ASC 320. The 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. In accordance with ASC 320, the securities that are bought and held principally for the purpose of selling them in the near term are classified as trading securities. Unrealized holding gains and losses for trading securities are included in earnings.
Investments not classified as trading or as held-to-maturity are classified as available-for-sale securities. Available-for-sale investments are reported at fair value, with unrealized gains and losses recorded in “Accumulated other comprehensive income (loss)”. Realized gains or losses are included in earnings during the period in which the gain or loss is realized. An impairment loss on the available-for-sale 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 represents the investments purchased by Baidu for its financial services and resold to third-party investors. These transactions do not meet the requirement of asset derecognition in accordance with ASC topic 860 (“ASC 860”), Transfers and Servicing. The Company recorded the proceeds related to the 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 were 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 the proceeds and payments related to the sale of financial products are classified as cash flows from financing activities in the consolidated statement of cash flows. Long-term investments The Company’s long-term investments consist of cost method investments, equity method investments, available-for-sale investments and investments accounted for at fair value. In accordance with ASC subtopic 325-20, Investments-Other: Cost Method Investments, the Company carries at cost its investments in investees which do not have readily determinable fair value and the Company does not have significant influence. The Company only adjusts for other-than-temporary declines in fair value and distributions 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 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 investment. 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 (“ASC 323”), Investments-Equity Method and Joint Ventures. 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 after the date of investment. The Company will discontinue applying the equity method if an investment (and additional financial supports to the investee, if any) has been reduced to zero. If the Company is not required to advance additional funds to an investee and the equity-method investment in ordinary shares is reduced to zero, the Company would recognize losses based on its percentage of the investment with the same liquidation preference for further investments made with a higher liquidation preference than ordinary shares. 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 evaluates the equity method investments for impairment under ASC 323. An impairment loss on the equity method investments is recognized in earnings when the decline in value is determined to be other-than-temporary. As available-for-sale investments are reported at fair value, when the decline in value is determined to be other-than-temporary, the impairment loss on the long-term available-for-sale investments would be recognized in the consolidated statements of comprehensive income. In accordance with ASC topic 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 topic 820 (“ASC 820”), Fair Value Measurements and Disclosures. These equity investments are classified within Level 3 in the fair value hierarchy, and changes in fair value are recorded in the consolidated income statements in the period the change occurs. 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. Certain financial assets that the Company bought as an agent on behalf of third-party investors have been isolated from the Company, even in bankruptcy or other receivership. These financial assets and associated liabilities are not recorded on the Company’s consolidated balance sheets. 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, capital lease obligation, notes payable and long-term loans. The carrying amounts of these financial instruments, except for long-term cost method investments, long-term equity method investments, long-term available-for-sale investments, derivative instruments, notes payable and long-term loans, approximate their fair values because of their generally short maturities. Available-for-sale equity investments, other invested securities, investments accounted for at fair value, and derivative instruments were adjusted to fair value at each reporting date. The carrying amounts of long-term held-to-maturity investments and long-term loans approximate their fair values due to the fact that the related interest rates approximate rates currently offered by financial institutions for similar debt instruments of comparable maturities. The fair value of notes payable is based on quoted price.
Research, Development and Computer Software Capitalization of software developed for internal use The Company capitalized certain internal use software development costs in accordance with ASC subtopic 350-40, Intangibles-Goodwill and Other: Internal-Use Software, amounting to RMB33 million, RMB4 million and nil (US$ nil) for the years ended December 31, 2015, 2016 and 2017, respectively. The Company capitalizes certain costs relating to software acquired, developed, or modified solely to meet the Company’s internal requirements and for which there are no substantive plans to market the software. These costs mainly include payroll and payroll-related costs for employees who are directly associated with and who devote time to the internal-use software projects during the application development stage. Capitalized internal-use software costs are included in “Intangible assets, net”. The amortization expense for capitalized software costs amounted to RMB13 million, RMB7 million and RMB8 million (US$1 million) for the years ended December 31, 2015, 2016 and 2017, respectively. The unamortized amount of capitalized internal use software development costs was RMB30 million and RMB22 million (US$3 million) as of December 31, 2016 and 2017, respectively. Research and development expenses Research and development expenses consist primarily of personnel-related costs. The Company expensed substantially all development costs incurred in the research and development of new products and new functionality added to the existing products except for certain internal use software development costs. 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, 2015, 2016 and 2017 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. The Company has two types of licensed copyrights, (i) non-exclusive licensed copyrights and (ii) exclusive licensed copyrights. With non-exclusive licensed copyrights, the Company has the right to broadcast the contents on its own internet platform. While, with exclusive licensed copyrights, in addition to the broadcasting right, the Company also has the right to sublicense the underlying contents 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. When the amortization pattern is revised, it is accounted for as a change in accounting estimate prospectively in accordance with ASC 250 (“ASC 250”), Accounting Changes and Error Corrections. The purchase cost of exclusive licensed copyrights includes a broadcasting right and a right to sublicense to third parties, and the Company allocates the 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. For the broadcasting right, which is the portion of an exclusive licensed copyright that generates direct and indirect advertising and membership revenues, the content costs are amortized in accordance with ASC 920-350 (“ASC 920-350”), Entertainment-Broadcasters: Intangibles—Goodwill and Other, using the same method as non-exclusive licensed copyrights as described above. For the right to sublicense to third parties, which is the portion of an exclusive licensed copyright that generates direct revenues, the content costs are amortized in accordance with ASC topic 926 (“ASC 926”), Entertainment—Films 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 revisits the forecasted total direct revenues on a periodic basis and any resulting changes to such estimates and the resulting amortization expense are accounted for prospectively as a change in accounting estimate in accordance with ASC 250. 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 licensed copyrights. The Company estimates advertising and membership cash flows for each category of the content. Estimates that impact advertising and membership cash flows include anticipated levels of demand for our online advertising and membership services and the expected selling prices of our advertisements and membership. For the right to sublicense to third parties, the Company assesses recoverability in accordance with ASC 926-20, Entertainment—Films: Other Assets—Film Costs. Goodwill and Intangible Assets Goodwill The Company assesses goodwill for impairment in accordance with ASC subtopic 350-20 (“ASC 350-20”), Intangibles—Goodwill 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, 2016, the Company had three reporting units, consisting of Search Services, Transaction Services, and iQIYI. As part of the combination of Search Services and Transaction Services segments into Baidu Core segment, the Company determined that there were only two reporting units, Baidu Core and iQIYI starting from April 2017. The goodwill previously allocated to Search Services and Transaction Services was reassigned to Baidu Core. 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-step quantitative 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 a qualitative assessment for the Baidu Core reporting unit. 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 each of the reporting units, and further impairment testing on goodwill was unnecessary as of December 31, 2017.
The Company elected to assess goodwill for impairment using the two-step process for the iQIYI reporting unit. Significant management judgment is 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 marketplace data to assess the reasonableness of assumptions such as discount rate, operating margins, and working capital levels. 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 economic lives or the terms of the related land use right contracts. All other intangible assets with finite lives except for the sublicensing rights obtained from barter transactions and certain licensed copyrights are amortized using the straight-line method over the estimated economic lives. Intangible assets have weighted average economic 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 (“ASC 350-30”), Intangibles-Goodwill and Other: General Intangibles 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 The Company recognizes revenue in accordance with ASC topic 605 (“ASC 605”), Revenue Recognition. Revenue is recognized when the following four revenue recognition criteria are met: (i) persuasive evidence of an arrangement exists, (ii) delivery has occurred or services have been provided, (iii) the selling price is fixed or determinable, and (iv) collectability is reasonably assured. Performance-based online marketing services Cost-per-click The Company’s auction-based P4P platform enables a customer to place its website link and related description on the Company’s search result list on the platform which could be accessed through personal computer or mobile devices. Customers make bids on keywords based on how much they are willing to pay for each click to their listings in the search results listed on the Company’s platform and the relevance between the keywords and the customer’s businesses. Internet users’ search of the keyword will trigger the display of the listings. The ranking of the customer’s listing depends on both the bidding price and the listing’s relevance to the keyword searched. Customers pay the Company only when a user clicks on one of its website links. Besides the Company’s traditional auction-based P4P services, the Company also displays in-feed marketing to targeted users through Baidu Feed. Customers pay the Company when a targeted user clicks the in-feed marketing and turns to its platforms. For the type of cost-per-clicks, revenue is recognized when all of the revenue recognition criteria set forth in ASC 605 are met, which is generally when a user clicks on one of the customer-sponsored links or in-feed 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 applications and the pre-determined ratios of completed transaction volumes, revenue is recognized when the specified performance criteria are met together with satisfaction of other applicable revenue recognition criteria as prescribed by ASC 605. Display-based online advertising services The Company provides display-based online advertising services to customer by integrating text description, image and video, and displaying the advertisements in a prominent position of the search result page, vertical search products or through Baidu Feed. The Company recognizes revenue in accordance with ASC 605, 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 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 the program through which the Company expands distribution of its customers’ sponsored links or advertisements by leveraging traffic of the Baidu Union members’ internet properties. The Company makes payments to Baidu Union members for acquisition of traffic. The Company recognizes gross revenue for the amount of fees it receives from its customers. Payments made to Baidu Union members are included in cost of revenues as traffic acquisition costs. Membership services The Company offers membership services which provide subscribing members access to streaming of premium content in exchange for a non-refundable upfront membership fee. Membership periods range from one month to twelve months. The receipt of membership fees is initially recorded as deferred revenue and we recognize revenue ratably over the membership period as services are rendered. 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. Gross interest income and interest costs recognized for the year ended December 31, 2017 were RMB3.5 billion (US$543 million) and RMB1.9 billion (US$288 million), respectively. Gross interest income and interest costs recognized for the years ended December 31, 2016 and 2015 were insignificant. Barter transactions Nonmonetary exchanges of licensed copyrights of video contents The Company 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 topic 845 (“ASC 845”), Nonmonetary Transactions, and records the transaction based on the fair value of the asset surrendered. Barter sublicensing revenues are recognized in accordance with ASC subtopic 926-605, Entertainment-Films; Revenue Recognition when all of the following criteria are met: persuasive evidence of a sub-licensing arrangement with a customer exists, the content is delivered or is available for immediate and unconditional delivery, the sub-license period of the arrangement has begun and the customer can begin its exploitation, exhibition, or sale, the arrangement fee is fixed or determinable and collection of the arrangement fee is reasonably assured, and when there are no other future obligations under the agreement. The Company estimates the fair value of the contents surrendered based on various factors, including comparable cash sublicensing transactions and relative size, scale, and market share of counterparties to the exchange. The attributable cost of the barter transaction 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 RMB350 million, RMB382 million and RMB763 million (US$117 million) and related costs of RMB265 million, RMB363 million and RMB650 million (US$100 million) for the years ended December 31, 2015, 2016 and 2017, respectively.
Other nonmonetary exchanges The Company engages in certain barter transactions other than licensed copyrights of video contents from time to time and in such situations follows the guidance set forth in ASC 845. While nonmonetary transactions are recorded at fair value, if such value is not determinable within reasonable limits, or the transaction lacks commercial substance, or the transaction is an exchange of a product or property held for sale in the ordinary course of business for a product or property to be sold in the same line of business to facilitate sales to customers other than the parties to the exchange, the transaction is recognized based on the carrying value of the product or services provided. The Company also engages in certain advertising barter transactions and follows the guidance set forth in ASC subtopic 605-20, Revenue Recognition: Services. The advertising barter transactions are recorded at fair value. If the fair value of the advertising surrendered in the barter transaction is not determinable within required limits, the barter transaction is recorded based on the carrying amount of the advertising surrendered, which is generally nil. The amount of revenues recognized for barter transactions other than licensed copyrights of video contents was insignificant for each of the years presented. Other revenue recognition related policies In accordance with ASC subtopic 605-25 (“ASC 605-25”), Revenue Recognition: Multiple-Deliverable Revenue Arrangements, for arrangements that include multiple deliverables, primarily for advertisements to be displayed in different spots, placed under different forms and occurring at different times, the Company would evaluate all the deliverables in the arrangement to determine whether they represent separate units of accounting. For the arrangements with deliverable items to be considered a separate unit of accounting, the Company allocates the total consideration of the arrangements based on their relative selling price, with the selling price of each deliverable determined using vendor-specific objective evidence of selling price, third-party evidence of selling price, or management’s best estimate of the selling price (“BESP”), and recognizes revenue as each service deliverable is provided. The Company considers all reasonably available information in determining the BESP, including both market and entity-specific factors. The Company delivers some of its online marketing services to end customers through engaging third-party distributors. In this context, the Company may provide cash incentives to distributors. The cash incentives are accounted for as a reduction of revenue in accordance with ASC subtopic 605-50 (“ASC 605-50”), Revenue Recognition: Customer Payments and Incentives. 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 award credits granted to customers in conjunction with a current sale of products or services as a multiple-element arrangement by analogy to ASC 605-25. The consideration allocated to the award credits is recorded as deferred revenue, based on the assumption that the customer will purchase the minimum amount of future service necessary to obtain the maximum award credits available. The deferred revenue is recognized as revenue proportionately as the future services are delivered to the customer or when the award credits expire. The Company provides coupons and credits to the end users in certain businesses. The coupons and credits can be used to reduce the purchase price or to redeem for gifts. Coupons issued to end users as a result of a concurrent sale are recognized as reductions of the corresponding revenue in accordance with ASC 605-50. Coupons issued to end users for free and without concurrent sales are recognized as advertising and promotional expenses upon the actual usage of the coupons. Credits provided to end users for redeeming gifts in the future are accrued as advertising and promotional expenses upon issuance.
Cost of Revenues Cost of revenues consists primarily of sales taxes (including business tax and value-added tax) and surcharges, traffic acquisition costs, bandwidth costs, depreciation, content costs, payroll and related costs of operations. The Company incurs sales taxes and surcharges in connection with the provision of online marketing services, technical and consultative service fees charged by its subsidiaries to VIEs and other taxable services in the PRC. In accordance with ASC subtopic 605-45, Revenue Recognition: Principal Agent Considerations, the Company includes the sales tax and surcharges incurred on its online marketing revenues in cost of revenues. The sales tax and surcharges in cost of revenues for the years ended December 31, 2015, 2016 and 2017 were RMB4.6 billion, RMB4.7 billion and RMB6.2 billion (US$951 million), respectively. Traffic acquisition costs represent the amounts paid or payable to Baidu Union members 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 members 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, 2015, 2016 and 2017 were RMB9.8 billion, RMB7.7 billion and RMB4.6 billion (US$700 million), 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 (“ASC 740”), Income Taxes, 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, 2015, 2016 and 2017, 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 (“ASC 718”), Compensation-Stock Compensation. 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 (“ASC 260”), Earnings Per Share, 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 accounts 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 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, if such estimate can be made and material, or states that such estimate is immaterial if it can be estimated but immaterial, or discloses that 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, amounts due from related parties and loan receivables. As of December 31, 2017, the Company has RMB100.7 billion (US$15.5 billion) in cash and cash equivalents, restricted cash, and short-term investments, 95.95% and 4.05% 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 Bank of China, China Construction Bank, China Merchants Bank, and Bank of Communications exceeded 10%, representing 25.26%, 18.83%, 12.56% and 10.50% of the Company’s total cash and cash equivalents, restricted cash, and short-term investments as of December 31, 2017, 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 2016, the Company had no single customer with a receivable balance exceeding 10% of the total accounts receivable balance. No customer or any Baidu Union member generated greater than 10% of total revenues in any of the years presented. Amounts due from related parties are typically unsecured and repayable on demand. 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; 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, short-term investments, long-term investments and notes payable 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$. The depreciation of the US$ against the RMB was approximately 6.29% in 2017. Most of the revenues and costs of the Company are denominated in RMB, while a portion of cash and cash equivalents, short-term financial assets, investments and notes payable are denominated in U.S. dollars. Any significant devaluation of RMB may materially and adversely 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 (“ASC 815”), Derivatives and Hedging, 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. The estimated fair values of derivative instruments are determined at discrete points in time based on the relevant market information. These estimates are calculated with reference to the market rates using industry standard valuation techniques. The fair value of the derivative instruments held by the Company was insignificant for all years presented. Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2014-09 (“ASU 2014-09”), Revenue from Contracts with Customers. ASU 2014-09 supersedes the revenue recognition requirements in ASC 605, and requires entities to recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled to in exchange for those goods or services. ASU 2014-09 is originally effective for the annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. ASU 2015-14, Revenue from Contracts with Customers, defers the effective date of ASU 2014-09 by one year. As a result, ASU 2014-09 is effective for annual reporting periods beginning after December 15, 2017 and interim periods therein. Early adoption is permitted to the original effective date. The Company will adopt the new standard effective January 1, 2018, using the modified retrospective method. The cumulative effect of initially applying the guidance will be recognized at the date of initial application is not expected to be material and prior periods will not be retrospectively adjusted. The Company has substantially completed the assessment and implementation work, and the main impact will be the reclassification of value-added tax from cost of revenues to net against revenues. If presented net of value-added tax, revenues for the year ended December 31, 2017 would have been approximately 5.6% lower than currently presented.
In January 2016, the FASB issued ASU No. 2016-01 (“ASU 2016-01”), Financial Instruments. ASU 2016-01 requires equity investments (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income. An entity may choose to measure equity investments that do not have readily determinable fair values at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer. ASU 2016-01 also simplifies the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment. When a qualitative assessment indicates that impairment exists, an entity is required to measure the investment at fair value. For public business entities, the amendments are effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted. The Company will adopt the new standard effective January 1, 2018. The adoption of ASU 2016-01 will increase the volatility of the Company’s “Other income, net”, resulting from the remeasurement of equity investments. The cumulative effect of initially applying the guidance is RMB676 million (US$104 million) will be reclassed from “Accumulated other comprehensive income” to “Retained earnings” at the date of initially applying the guidance. In February 2016, the FASB issued ASU No. 2016-02 (“ASU 2016-02”), Leases. 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 in the first quarter of 2019. The Company is currently evaluating the impact of adopting this standard on its consolidated financial statements. |

| Investments | 4. INVESTMENTS Short-term Investments As of December 31, 2017, all of the short-term held-to-maturity investments were time deposits in commercial banks with maturities of less than one year. The short-term available-for-sale investments are debt securities with maturities of less than one year purchased from commercial banks and other financial institutions, and equity securities of a publicly listed company.

| Income Taxes | 13. 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 statutory income tax rate has been reduced from 38.0% to approximately 35.6%, 33.5% and 31.7% effective for the years ended December 31, 2015, 2016 and 2017, 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 and Baidu China enjoyed a reduced tax rate of 10% as qualified KSEs in 2015 and 2016. Baidu International also enjoyed a reduced tax rate of 10% as qualified KSE in 2016. 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 2018, 2019 or 2020. 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-residententerprise 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, 2016 and 2017 are as follows:
As of December 31, 2017, the Company had net losses of approximately RMB7.8 billion (US$1.2 billion) deriving from entities in the PRC, Hong Kong and Japan. The net loss in the PRC and Japan can be carried forward for five years and nine years, respectively, to offset future net profit for income tax purposes. The net loss of entities in the PRC and Japan will begin to expire in 2018, if not utilized. The net loss 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, 2016 and 2017, 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 2017 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 2017, the total amount of undistributed earnings from the PRC subsidiaries for which no withholding tax has been accrued was RMB113.1 billion (US$17.4 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 | 15. 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 RMB547 million (US$84 million) as of December 31, 2017. 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 RMB647 million, RMB494 million and RMB507 million (US$78 million) for the years ended December 31, 2015, 2016 and 2017, respectively. Total operating lease expense for internet data center (“IDC”) facilities was RMB3.7 billion, RMB4.7 billion and RMB5.6 billion (US$854 million) for the years ended December 31, 2015, 2016 and 2017 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, 2017:
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. Commitments for Licensed Copyrights The Company enters into non-cancelable licensing agreements with third-party vendors to acquire licensed copyrights of video contents for its online video platform. Future minimum payments under non-cancelable licensing agreements consist of the following as of December 31, 2017:
Guarantees The Company accounts for guarantees in accordance with ASC topic 460 (“ASC 460”), Guarantees. 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, 2016 and 2017. Litigation The Group was involved in certain cases pending in various PRC and Brazil courts and arbitration as of December 31, 2017. 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 estimated loss amounts were insignificant. |

| Redeemable Noncontrolling Interests | 16. REDEEMABLE NONCONTROLLING INTERESTS
In November 2014, iQIYI completed a round of preferred shares financing with US$300 million from the external preferred shareholders. A negative accretion of RMB400 million (US$61 million) was recorded as an increase to the net income attributable to ordinary shareholders for the year ended December 31, 2017 as a result of the change in redemption price. As the above preferred shares are not currently redeemable and this change in redemption price was considered a change in accounting estimate in accordance with ASC topic 480 (“ASC 480”), Distinguishing Liabilities from Equity, and a new effective interest rate was determined and prospectively applied to accrete the carrying amount of the above preferred shares to the future expected contractual cash flows (the new redemption amount). In October 2017, the US$1.2 billion iQIYI 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. 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 are accounted for as redeemable noncontrolling interests. In August 2017, the Company completed the disposal of Xiaodu to Rajax Holding for its equity shares.
The Company accounts for the changes in accretion to the redemption value in accordance with ASC 480. 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 | 17. 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 nil, 91,667 and 200,000 in the years ended December 31, 2015, 2016 and 2017, respectively. As of December 31, 2017, there were 27,614,978 and 7,201,254 Class A and Class B ordinary shares outstanding, respectively. As of December 31, 2016 and 2017, 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 another 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 in the open market or through privately negotiated transactions, depending on market conditions and in accordance with applicable rules and regulations. The Company repurchased 603,726, nil and 145,783 Class A ordinary shares from the open market with an aggregate purchase price of US$990 million, nil and US$251 million during the years ended December 31, 2015, 2016 and 2017. 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 RMB13.7 billion and RMB18.6 billion (US$2.9 billion) as of December 31, 2016 and 2017, 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, 2015, 2016 and 2017:

EARNINGS PER SHARE (“EPS”) A reconciliation of net income attributable to Baidu, Inc. in the consolidated statements of comprehensive income to the numerator for the computation of basic and diluted per share for the years ended December 31, 2015, 2016 and 2017 is as follows:

| Share-Based Awards Plan | 19. SHARE-BASED AWARDS PLAN Baidu, Inc. Incentive compensation plans 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 and consultants of the Company. However, the Company may grant ISOs only to its employees. The Company reserved 3,428,777 ordinary shares for issuance under the 2008 Plan, which will expire in the year 2018. The vesting schedule, time and condition to exercise options will be 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. 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, 2017:
The aggregate intrinsic value in the table above represents the difference between the Company’s closing stock price on the last trading day in 2017 and the exercise price. Total intrinsic value of options exercised for the years ended December 31, 2015, 2016 and 2017 was RMB200 million, RMB143 million and RMB403 million (US$62 million), respectively. The total fair value of options vested during the years ended December 31, 2015, 2016 and 2017 was RMB149 million, RMB225 million and RMB195 million (US$30 million), respectively. As of December 31, 2017, there was RMB592 million (US$91 million) unrecognized share-based compensation cost related to share options. That deferred cost is expected to be recognized over a weighted-average vesting period of 2.8 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, 2015, 2016 and 2017 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, 2015, 2016, and 2017 was US$790.00, US$659.70, and US$747.45, respectively. Restricted Shares Restricted Shares activity for the year ended December 31, 2017 was as follows:
The total fair value of the Restricted Shares vested during the years ended December 31, 2015, 2016 and 2017 was RMB701 million, RMB1.1 billion, RMB2.1 billion (US$317 million), respectively. The weighted-average grant-date fair value of the Restricted Shares granted during the years ended December 31, 2015, 2016, and 2017 was US$1,979.30, US$1,755.90, and US$1,977.57, respectively. As of December 31, 2017, there was RMB5.3 billion (US$813 million) unrecognized share-based compensation cost related to Restricted Shares. That deferred cost will be recognized over a weighted-average vesting period of 2.9 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 iQIYI also has equity incentive plans granting share-based awards. As of December 31, 2017, there was RMB476 million (US$73 million) unrecognized compensation cost related to non-vested share options granted by iQIYI to its employees and directors. That deferred cost will be recognized over a weighted-average period of 2.8 years and may be adjusted for future changes in estimated forfeitures. The following table summarizes the share-based compensation cost recognized by iQIYI:
Subsidiaries-Others Other subsidiaries apart from iQIYI also have equity incentive plans granting share-based awards. Total share-based compensation expenses recognized and unrecognized were insignificant, both individually and in aggregate, for all years presented. The following table summarizes the total share-based compensation cost recognized by the Group:

| Segment Reporting | 21. SEGMENT REPORTING The operations of the Company are organized into two segments, consisting of Baidu Core and iQIYI. Baidu Core mainly consisting of keyword-based marketing services targeted at and triggered by internet users’ search queries, which mainly include P4P services and other online marketing services, artificial intelligence-enabled new business initiatives and internet financial services. iQIYI is an online video platform with a content library that includes licensed movies, television series, cartoons, variety shows, self-produced programs and other programs. The Company derives the results of the segments directly from its internal management reporting system. The CODM reviews the performance of each segment based on its operating results and uses these results to evaluate the performance of, and to allocate resources to, each of the segments. Because substantially all of the Group’s long-lived assets and revenues are located in and derived from the PRC, geographical segments are not presented.

| Fair Value Measurement | 22. 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 and investments accounted for at fair value 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 available-for-sale equity investments in the equity securities of publicly listed companies are measured using quoted market prices. Investments accounted at the fair value are primarily 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 certain debt and equity investments at fair value on a nonrecurring basis only if an impairment charge is recognized. 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 were categorized as Level 2 in the fair value hierarchy.
Assets and liabilities measured or disclosed at fair value are summarized below:
In 2016, the value of a cost method investment was written down to zero, as a result of declining financial performance and a change in the business circumstances of the investee. The corresponding impairment charge incurred was recorded in earnings for the year then ended.
In 2017, the carrying value of certain long-term investments were written down to their fair values, as a result of declining financial performances and changes in the business circumstances of these investees. The corresponding impairment charges incurred were recorded accordingly. 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 including but not limited to the pricing of recent rounds of financing, future cash flow forecasts, liquidity factors, and selection of the comparable companies. For investments in listed companies, the Company mainly considered the quoted share price. |

| Accounting Policies [Abstract] | |||||||||||||||||||||||||
| Principles of Consolidation | 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 | Use of Estimates The preparation of 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 accounts receivable allowances, credit loss allowance for micro loan receivables, fair values of options to purchase the Company’s or its subsidiaries’ ordinary shares, fair values of certain debt and equity investments, amortization and impairment of licensed copyrights, 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 and acquisition of equity method investees, 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 to translate its each month for income and expense items. Any translation gains (losses) are recorded in other comprehensive income (loss). Transactions denominated in foreign currencies are translated into the functional currency at the exchange rates prevailing on the transaction dates. Assets and liabilities denominated in foreign currencies are translated 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 The Company historically had only one single reportable segment because the Company’s chief operating decision maker (“CODM”) formerly relied on the consolidated results of operations when making decisions on allocating resources and assessing performance of the Company. Starting from the quarter ended June 30, 2015, the Company reorganized its operation into three segments, consisting of the Search Services, Transaction Services and iQIYI as a result of its expansion of offerings into multiple services. Starting from April 2017, Search Services and Transaction Services were combined into one segment, namely, Baidu Core. The change in reportable segments reflects the Company’s strategic shift and the operational change to de-emphasized its transaction services business and shifted such resources to support its online marketing services. As of December 31, 2017, the Company had two reportable segments, Baidu Core and iQIYI. Baidu Core mainly provides keyword-based marketing services targeted at and triggered by internet users’ search queries, which mainly include pay-for-performance (“P4P”) services and other online marketing services, artificial intelligence-enabled new business initiatives and internet financial services. iQIYI is an online entertainment service provider that, offers original, professionally produced and partner-generated content on its platform. The Company’s chief executive officer, who has been identified as the CODM, now reviews the operating results of Baidu Core and iQIYI in order 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 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. 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, forecasted life cycle and forecasted cash flows over that period. |
||||||||||||||||||||||||
| Cash and Cash Equivalents | Cash and Cash Equivalents 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 for the remaining payments in relation to compensation for post-combination services, and the cash balances deposited at certain banks as online payment service deposits. |
||||||||||||||||||||||||
| 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. Bad debts are written off as incurred. 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 cash due from the third-party online payment service providers for clearing transactions. The cash was 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 after all collection efforts have been exhausted. The balances are included in “Other current assets, net” on the consolidated balance sheets. As of December 31, 2016 and 2017, 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. |

| 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 investments in accordance with ASC topic 320 (“ASC 320”), Investments – Debt and Equity Securities. The Company classifies the short-term investments in debt and equity securities as “held-to-maturity” 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. The securities that the Company has the positive intent and the 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 the Company’s policy and ASC 320. The 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. In accordance with ASC 320, the securities that are bought and held principally for the purpose of selling them in the near term are classified as trading securities. Unrealized holding gains and losses for trading securities are included in earnings.
Investments not classified as trading or as held-to-maturity are classified as available-for-sale securities. Available-for-sale investments are reported at fair value, with unrealized gains and losses recorded in “Accumulated other comprehensive income (loss)”. Realized gains or losses are included in earnings during the period in which the gain or loss is realized. An impairment loss on the available-for-sale 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 represents the investments purchased by Baidu for its financial services and resold to third-party investors. These transactions do not meet the requirement of asset derecognition in accordance with ASC topic 860 (“ASC 860”), Transfers and Servicing. The Company recorded the proceeds related to the 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 were 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 the proceeds and payments related to the sale of financial products are classified as cash flows from financing activities in the consolidated statement of cash flows. Long-term investments The Company’s long-term investments consist of cost method investments, equity method investments, available-for-sale investments and investments accounted for at fair value. In accordance with ASC subtopic 325-20, Investments-Other: Cost Method Investments, the Company carries at cost its investments in investees which do not have readily determinable fair value and the Company does not have significant influence. The Company only adjusts for other-than-temporary declines in fair value and distributions 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 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 investment. 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 (“ASC 323”), Investments-Equity Method and Joint Ventures. 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 after the date of investment. The Company will discontinue applying the equity method if an investment (and additional financial supports to the investee, if any) has been reduced to zero. If the Company is not required to advance additional funds to an investee and the equity-method investment in ordinary shares is reduced to zero, the Company would recognize losses based on its percentage of the investment with the same liquidation preference for further investments made with a higher liquidation preference than ordinary shares. 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 evaluates the equity method investments for impairment under ASC 323. An impairment loss on the equity method investments is recognized in earnings when the decline in value is determined to be other-than-temporary. As available-for-sale investments are reported at fair value, when the decline in value is determined to be other-than-temporary, the impairment loss on the long-term available-for-sale investments would be recognized in the consolidated statements of comprehensive income. In accordance with ASC topic 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 topic 820 (“ASC 820”), Fair Value Measurements and Disclosures. These equity investments are classified within Level 3 in the fair value hierarchy, and changes in fair value are recorded in the consolidated income statements in the period the change occurs. |
||||||||||||||||||||||||
| 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. Certain financial assets that the Company bought as an agent on behalf of third-party investors have been isolated from the Company, even in bankruptcy or other receivership. These financial assets and associated liabilities are not recorded on the Company’s consolidated balance sheets. |
||||||||||||||||||||||||
| 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, capital lease obligation, notes payable and long-term loans. The carrying amounts of these financial instruments, except for long-term cost method investments, long-term equity method investments, long-term available-for-sale investments, derivative instruments, notes payable and long-term loans, approximate their fair values because of their generally short maturities. Available-for-sale equity investments, other invested securities, investments accounted for at fair value, and derivative instruments were adjusted to fair value at each reporting date. The carrying amounts of long-term held-to-maturity investments and long-term loans approximate their fair values due to the fact that the related interest rates approximate rates currently offered by financial institutions for similar debt instruments of comparable maturities. The fair value of notes payable is based on quoted price. |
||||||||||||||||||||||||
| Research, Development and Computer Software | Research, Development and Computer Software Capitalization of software developed for internal use The Company capitalized certain internal use software development costs in accordance with ASC subtopic 350-40, Intangibles-Goodwill and Other: Internal-Use Software, amounting to RMB33 million, RMB4 million and nil (US$ nil) for the years ended December 31, 2015, 2016 and 2017, respectively. The Company capitalizes certain costs relating to software acquired, developed, or modified solely to meet the Company’s internal requirements and for which there are no substantive plans to market the software. These costs mainly include payroll and payroll-related costs for employees who are directly associated with and who devote time to the internal-use software projects during the application development stage. Capitalized internal-use software costs are included in “Intangible assets, net”. The amortization expense for capitalized software costs amounted to RMB13 million, RMB7 million and RMB8 million (US$1 million) for the years ended December 31, 2015, 2016 and 2017, respectively. The unamortized amount of capitalized internal use software development costs was RMB30 million and RMB22 million (US$3 million) as of December 31, 2016 and 2017, respectively. Research and development expenses Research and development expenses consist primarily of personnel-related costs. The Company expensed substantially all development costs incurred in the research and development of new products and new functionality added to the existing products except for certain internal use software development costs. |
||||||||||||||||||||||||
| 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, 2015, 2016 and 2017 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. The Company has two types of licensed copyrights, (i) non-exclusive licensed copyrights and (ii) exclusive licensed copyrights. With non-exclusive licensed copyrights, the Company has the right to broadcast the contents on its own internet platform. While, with exclusive licensed copyrights, in addition to the broadcasting right, the Company also has the right to sublicense the underlying contents 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. When the amortization pattern is revised, it is accounted for as a change in accounting estimate prospectively in accordance with ASC 250 (“ASC 250”), Accounting Changes and Error Corrections. The purchase cost of exclusive licensed copyrights includes a broadcasting right and a right to sublicense to third parties, and the Company allocates the 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. For the broadcasting right, which is the portion of an exclusive licensed copyright that generates direct and indirect advertising and membership revenues, the content costs are amortized in accordance with ASC 920-350 (“ASC 920-350”), Entertainment-Broadcasters: Intangibles—Goodwill and Other, using the same method as non-exclusive licensed copyrights as described above. For the right to sublicense to third parties, which is the portion of an exclusive licensed copyright that generates direct revenues, the content costs are amortized in accordance with ASC topic 926 (“ASC 926”), Entertainment—Films 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 revisits the forecasted total direct revenues on a periodic basis and any resulting changes to such estimates and the resulting amortization expense are accounted for prospectively as a change in accounting estimate in accordance with ASC 250. 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 licensed copyrights. The Company estimates advertising and membership cash flows for each category of the content. Estimates that impact advertising and membership cash flows include anticipated levels of demand for our online advertising and membership services and the expected selling prices of our advertisements and membership. For the right to sublicense to third parties, the Company assesses recoverability in accordance with ASC 926-20, Entertainment—Films: Other Assets—Film Costs. |
||||||||||||||||||||||||
| Goodwill and Intangible Assets | Goodwill and Intangible Assets Goodwill The Company assesses goodwill for impairment in accordance with ASC subtopic 350-20 (“ASC 350-20”), Intangibles—Goodwill 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, 2016, the Company had three reporting units, consisting of Search Services, Transaction Services, and iQIYI. As part of the combination of Search Services and Transaction Services segments into Baidu Core segment, the Company determined that there were only two reporting units, Baidu Core and iQIYI starting from April 2017. The goodwill previously allocated to Search Services and Transaction Services was reassigned to Baidu Core. 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-step quantitative 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 a qualitative assessment for the Baidu Core reporting unit. 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 each of the reporting units, and further impairment testing on goodwill was unnecessary as of December 31, 2017.
The Company elected to assess goodwill for impairment using the two-step process for the iQIYI reporting unit. Significant management judgment is 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 marketplace data to assess the reasonableness of assumptions such as discount rate, operating margins, and working capital levels. 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 economic lives or the terms of the related land use right contracts. All other intangible assets with finite lives except for the sublicensing rights obtained from barter transactions and certain licensed copyrights are amortized using the straight-line method over the estimated economic lives. Intangible assets have weighted average economic 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 (“ASC 350-30”), Intangibles-Goodwill and Other: General Intangibles Other than Goodwill. |
||||||||||||||||||||||||
| 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 recognizes revenue in accordance with ASC topic 605 (“ASC 605”), Revenue Recognition. Revenue is recognized when the following four revenue recognition criteria are met: (i) persuasive evidence of an arrangement exists, (ii) delivery has occurred or services have been provided, (iii) the selling price is fixed or determinable, and (iv) collectability is reasonably assured. Performance-based online marketing services Cost-per-click The Company’s auction-based P4P platform enables a customer to place its website link and related description on the Company’s search result list on the platform which could be accessed through personal computer or mobile devices. Customers make bids on keywords based on how much they are willing to pay for each click to their listings in the search results listed on the Company’s platform and the relevance between the keywords and the customer’s businesses. Internet users’ search of the keyword will trigger the display of the listings. The ranking of the customer’s listing depends on both the bidding price and the listing’s relevance to the keyword searched. Customers pay the Company only when a user clicks on one of its website links. Besides the Company’s traditional auction-based P4P services, the Company also displays in-feed marketing to targeted users through Baidu Feed. Customers pay the Company when a targeted user clicks the in-feed marketing and turns to its platforms. For the type of cost-per-clicks, revenue is recognized when all of the revenue recognition criteria set forth in ASC 605 are met, which is generally when a user clicks on one of the customer-sponsored links or in-feed 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 applications and the pre-determined ratios of completed transaction volumes, revenue is recognized when the specified performance criteria are met together with satisfaction of other applicable revenue recognition criteria as prescribed by ASC 605. Display-based online advertising services The Company provides display-based online advertising services to customer by integrating text description, image and video, and displaying the advertisements in a prominent position of the search result page, vertical search products or through Baidu Feed. The Company recognizes revenue in accordance with ASC 605, 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 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 the program through which the Company expands distribution of its customers’ sponsored links or advertisements by leveraging traffic of the Baidu Union members’ internet properties. The Company makes payments to Baidu Union members for acquisition of traffic. The Company recognizes gross revenue for the amount of fees it receives from its customers. Payments made to Baidu Union members are included in cost of revenues as traffic acquisition costs. Membership services The Company offers membership services which provide subscribing members access to streaming of premium content in exchange for a non-refundable upfront membership fee. Membership periods range from one month to twelve months. The receipt of membership fees is initially recorded as deferred revenue and we recognize revenue ratably over the membership period as services are rendered. 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. Gross interest income and interest costs recognized for the year ended December 31, 2017 were RMB3.5 billion (US$543 million) and RMB1.9 billion (US$288 million), respectively. Gross interest income and interest costs recognized for the years ended December 31, 2016 and 2015 were insignificant. Barter transactions Nonmonetary exchanges of licensed copyrights of video contents The Company 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 topic 845 (“ASC 845”), Nonmonetary Transactions, and records the transaction based on the fair value of the asset surrendered. Barter sublicensing revenues are recognized in accordance with ASC subtopic 926-605, Entertainment-Films; Revenue Recognition when all of the following criteria are met: persuasive evidence of a sub-licensing arrangement with a customer exists, the content is delivered or is available for immediate and unconditional delivery, the sub-license period of the arrangement has begun and the customer can begin its exploitation, exhibition, or sale, the arrangement fee is fixed or determinable and collection of the arrangement fee is reasonably assured, and when there are no other future obligations under the agreement. The Company estimates the fair value of the contents surrendered based on various factors, including comparable cash sublicensing transactions and relative size, scale, and market share of counterparties to the exchange. The attributable cost of the barter transaction 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 RMB350 million, RMB382 million and RMB763 million (US$117 million) and related costs of RMB265 million, RMB363 million and RMB650 million (US$100 million) for the years ended December 31, 2015, 2016 and 2017, respectively.
Other nonmonetary exchanges The Company engages in certain barter transactions other than licensed copyrights of video contents from time to time and in such situations follows the guidance set forth in ASC 845. While nonmonetary transactions are recorded at fair value, if such value is not determinable within reasonable limits, or the transaction lacks commercial substance, or the transaction is an exchange of a product or property held for sale in the ordinary course of business for a product or property to be sold in the same line of business to facilitate sales to customers other than the parties to the exchange, the transaction is recognized based on the carrying value of the product or services provided. The Company also engages in certain advertising barter transactions and follows the guidance set forth in ASC subtopic 605-20, Revenue Recognition: Services. The advertising barter transactions are recorded at fair value. If the fair value of the advertising surrendered in the barter transaction is not determinable within required limits, the barter transaction is recorded based on the carrying amount of the advertising surrendered, which is generally nil. The amount of revenues recognized for barter transactions other than licensed copyrights of video contents was insignificant for each of the years presented. Other revenue recognition related policies In accordance with ASC subtopic 605-25 (“ASC 605-25”), Revenue Recognition: Multiple-Deliverable Revenue Arrangements, for arrangements that include multiple deliverables, primarily for advertisements to be displayed in different spots, placed under different forms and occurring at different times, the Company would evaluate all the deliverables in the arrangement to determine whether they represent separate units of accounting. For the arrangements with deliverable items to be considered a separate unit of accounting, the Company allocates the total consideration of the arrangements based on their relative selling price, with the selling price of each deliverable determined using vendor-specific objective evidence of selling price, third-party evidence of selling price, or management’s best estimate of the selling price (“BESP”), and recognizes revenue as each service deliverable is provided. The Company considers all reasonably available information in determining the BESP, including both market and entity-specific factors. The Company delivers some of its online marketing services to end customers through engaging third-party distributors. In this context, the Company may provide cash incentives to distributors. The cash incentives are accounted for as a reduction of revenue in accordance with ASC subtopic 605-50 (“ASC 605-50”), Revenue Recognition: Customer Payments and Incentives. 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 award credits granted to customers in conjunction with a current sale of products or services as a multiple-element arrangement by analogy to ASC 605-25. The consideration allocated to the award credits is recorded as deferred revenue, based on the assumption that the customer will purchase the minimum amount of future service necessary to obtain the maximum award credits available. The deferred revenue is recognized as revenue proportionately as the future services are delivered to the customer or when the award credits expire. The Company provides coupons and credits to the end users in certain businesses. The coupons and credits can be used to reduce the purchase price or to redeem for gifts. Coupons issued to end users as a result of a concurrent sale are recognized as reductions of the corresponding revenue in accordance with ASC 605-50. Coupons issued to end users for free and without concurrent sales are recognized as advertising and promotional expenses upon the actual usage of the coupons. Credits provided to end users for redeeming gifts in the future are accrued as advertising and promotional expenses upon issuance. |

| Cost of Revenues | Cost of Revenues Cost of revenues consists primarily of sales taxes (including business tax and value-added tax) and surcharges, traffic acquisition costs, bandwidth costs, depreciation, content costs, payroll and related costs of operations. The Company incurs sales taxes and surcharges in connection with the provision of online marketing services, technical and consultative service fees charged by its subsidiaries to VIEs and other taxable services in the PRC. In accordance with ASC subtopic 605-45, Revenue Recognition: Principal Agent Considerations, the Company includes the sales tax and surcharges incurred on its online marketing revenues in cost of revenues. The sales tax and surcharges in cost of revenues for the years ended December 31, 2015, 2016 and 2017 were RMB4.6 billion, RMB4.7 billion and RMB6.2 billion (US$951 million), respectively. Traffic acquisition costs represent the amounts paid or payable to Baidu Union members 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 members 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, 2015, 2016 and 2017 were RMB9.8 billion, RMB7.7 billion and RMB4.6 billion (US$700 million), 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 (“ASC 740”), Income Taxes, 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, 2015, 2016 and 2017, 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 (“ASC 718”), Compensation-Stock Compensation. 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 (“ASC 260”), Earnings Per Share, 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 accounts 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 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, if such estimate can be made and material, or states that such estimate is immaterial if it can be estimated but immaterial, or discloses that 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, amounts due from related parties and loan receivables. As of December 31, 2017, the Company has RMB100.7 billion (US$15.5 billion) in cash and cash equivalents, restricted cash, and short-term investments, 95.95% and 4.05% 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 Bank of China, China Construction Bank, China Merchants Bank, and Bank of Communications exceeded 10%, representing 25.26%, 18.83%, 12.56% and 10.50% of the Company’s total cash and cash equivalents, restricted cash, and short-term investments as of December 31, 2017, 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 2016, the Company had no single customer with a receivable balance exceeding 10% of the total accounts receivable balance. No customer or any Baidu Union member generated greater than 10% of total revenues in any of the years presented. Amounts due from related parties are typically unsecured and repayable on demand. 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; 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, short-term investments, long-term investments and notes payable 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$. The depreciation of the US$ against the RMB was approximately 6.29% in 2017. Most of the revenues and costs of the Company are denominated in RMB, while a portion of cash and cash equivalents, short-term financial assets, investments and notes payable are denominated in U.S. dollars. Any significant devaluation of RMB may materially and adversely 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 (“ASC 815”), Derivatives and Hedging, 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. The estimated fair values of derivative instruments are determined at discrete points in time based on the relevant market information. These estimates are calculated with reference to the market rates using industry standard valuation techniques. The fair value of the derivative instruments held by the Company was insignificant for all years presented. |

| Recent Accounting Pronouncements | Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2014-09 (“ASU 2014-09”), Revenue from Contracts with Customers. ASU 2014-09 supersedes the revenue recognition requirements in ASC 605, and requires entities to recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled to in exchange for those goods or services. ASU 2014-09 is originally effective for the annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. ASU 2015-14, Revenue from Contracts with Customers, defers the effective date of ASU 2014-09 by one year. As a result, ASU 2014-09 is effective for annual reporting periods beginning after December 15, 2017 and interim periods therein. Early adoption is permitted to the original effective date. The Company will adopt the new standard effective January 1, 2018, using the modified retrospective method. The cumulative effect of initially applying the guidance will be recognized at the date of initial application is not expected to be material and prior periods will not be retrospectively adjusted. The Company has substantially completed the assessment and implementation work, and the main impact will be the reclassification of value-added tax from cost of revenues to net against revenues. If presented net of value-added tax, revenues for the year ended December 31, 2017 would have been approximately 5.6% lower than currently presented.
In January 2016, the FASB issued ASU No. 2016-01 (“ASU 2016-01”), Financial Instruments. ASU 2016-01 requires equity investments (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income. An entity may choose to measure equity investments that do not have readily determinable fair values at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer. ASU 2016-01 also simplifies the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment. When a qualitative assessment indicates that impairment exists, an entity is required to measure the investment at fair value. For public business entities, the amendments are effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted. The Company will adopt the new standard effective January 1, 2018. The adoption of ASU 2016-01 will increase the volatility of the Company’s “Other income, net”, resulting from the remeasurement of equity investments. The cumulative effect of initially applying the guidance is RMB676 million (US$104 million) will be reclassed from “Accumulated other comprehensive income” to “Retained earnings” at the date of initially applying the guidance. In February 2016, the FASB issued ASU No. 2016-02 (“ASU 2016-02”), Leases. 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 in the first quarter of 2019. The Company is currently evaluating the impact of adopting this standard on its consolidated financial statements. |

- Definition Investments in debt and equity securities which are categorized neither as held-to-maturity nor trading and which are intended to be sold or mature more than one year from the balance sheet date or operating cycle, if longer. Such securities are reported at fair value; unrealized gains (losses) related to Available-for-sale Securities are excluded from earnings and reported in a separate component of shareholders' equity (other comprehensive income), unless the Available-for-sale security is designated as a hedge or is determined to have had an other than temporary decline in fair value below its amortized cost basis. All or a portion of the unrealized holding gain (loss) of an Available-for-sale security that is designated as being hedged in a fair value hedge is recognized in earnings during the period of the hedge, as are other than temporary declines in fair value below the cost basis for investments in equity securities and debt securities that an entity intends to sell or it is more likely than not that it will be required to sell before the recovery of its amortized cost basis. Other than temporary declines in fair value below the cost basis for debt securities categorized as Available-for-sale that an entity does not intend to sell and for which it is not more likely than not that the entity will be required to sell before the recovery of its amortized cost basis are bifurcated into credit losses and losses related to all other factors.
