Organization

1.	ORGANIZATION

Autohome Inc., formerly known as Sequel Limited (the “Company”), was incorporated under the laws of the Cayman Islands on June 23, 2008. Upon incorporation, the Company was 100% owned by Telstra Holdings Pty Ltd. (“Telstra”). On June 27, 2008 (the “Acquisition date”), the Company acquired Cheerbright International Holdings Limited (“Cheerbright”), China Topside Co., Ltd. (“China Topside”), and Norstar Advertising Media Holdings Co., Ltd. (“Norstar”), and their respective wholly foreign-owned enterprises and variable interest entities (“VIEs”). Subsequent to the acquisition, the Company was owned 55% by Telstra, and 45% by the selling shareholders of Cheerbright, China Topside and Norstar. In May 2012, Telstra acquired additional ordinary shares of the Company from other shareholders. In June 2016, Telstra completed the sale of approximately 47.4% of the total issued shares in the Company to Ping An Insurance (Group) Company of China Ltd. (“Ping An”). After the consummation of the sale, Ping An became the Company’s controlling shareholder.

The Company successfully completed its IPO and listing of 8,993,000 American Depositary Shares (“ADSs”) on the New York Stock Exchange in December, 2013, and raised net proceeds of US$142,590 from the offering. Each ADS represents one ordinary share. Upon the completion of IPO in December, 2013, the Company’s dual-class ordinary share structure came into effect (Note 16). Upon the completion of follow-on offering in November 2014, 2,424,801 ADSs were issued by the Company and 6,964,612 Class B ordinary shares were converted into Class A ordinary shares. The net proceeds from the follow-on offering amounted to US$97,344 net of issuance cost. Upon the transfer of 47.4% share ownership by Telstra to Ping An in June 2016, all the Class B ordinary shares were converted into Class A ordinary shares. As of December 31, 2016, the Company had ordinary shares outstanding, all comprised of 115,297,224 Class A ordinary shares. Ping An became the Company’s controlling shareholder holding 47.2% of the total equity interest and voting rights, respectively in the Company as of December 31, 2016.

The Company, through its subsidiaries and VIEs (as disclosed in the table below), is engaged in the provision of media services, leads generation services and online marketplace in the People’s Republic of China (the “PRC”).

As of December 31, 2016, the Company’s principal subsidiaries and VIEs where Autohome WFOE and Chezhiying WFOE are the primary beneficiaries include the following entities:

The Company, its subsidiaries and VIEs are hereinafter collectively referred to as the “Group”. The Group provides media services, leads generation services and online marketplace through its websites and mobile applications. These services are offered to automakers and dealers, and advertising agencies that represent automakers and dealers in the automobile industry. 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 wholly-owned subsidiaries and VIEs in the PRC.

PRC laws and regulations prohibit or restrict foreign ownership of internet content and online advertising businesses. To comply with these foreign ownership restrictions, the Company and its subsidiaries operate websites and provide online advertising services in the PRC through VIEs. The paid-in capital of the VIEs was funded by the Company’s PRC subsidiaries, Autohome WFOE and Chezhiying WFOE, through loans extended to the VIEs’ shareholders (“Nominee Shareholders”). The effective control of the VIEs is held by WFOEs, through a series of contractual agreements (the “Contractual Agreements”). As a result of the Contractual Agreements, the WFOEs maintain the ability to control the VIEs, are entitled to substantially all of the economic benefits from the VIEs and are obligated to absorb all of the VIE’s expected losses.

In September 2016 and March 2017, the then individual nominee shareholders of Shengtuo Hongyuan, Guangzhou Advertising, Autohome Information and Shanghai Advertising, entered into Equity Interest Purchase Agreements and Debt Transfer and Offset Agreements with Min Lu and Haiyun Lei, pursuant to which the then individual nominee shareholders transferred all of their equity interest in each of the entities to Min Lu and Haiyun Lei. In September 2016 and in March 2017, each of Autohome WFOE and Chezhiying WFOE, and each of Shengtuo Hongyuan and its two subsidiaries, Guangzhou Advertising, Autohome Information and its two subsidiaries and Shanghai Advertising, and each of Min Lu and Haiyun Lei, as the individual nominee shareholder of VIEs, entered into contractual agreements.

Despite the lack of technical majority ownership, there exists a parent-subsidiary relationship between the Company and the VIEs through the irrevocable power of attorney agreement, whereby the Nominee Shareholders effectively assigned all of their voting rights underlying their equity interest in the VIEs to the WFOEs. In addition, through the Contractual Agreements the Company demonstrates its ability and intention to continue to exercise the ability to absorb substantially all of the expected losses and majority of the profits of the VIEs through the WFOEs.

Thus, the Company is also considered the primary beneficiary of the VIEs through the WFOEs. As a result of the above, the Company consolidates the VIEs in accordance with SEC Regulation SX-3A-02 and Accounting Standards Codification (“ASC”) 810-10 (“ASC 810-10”) Consolidation: Overall.

The following is a summary of the Contractual Agreements:

Exclusive technical consulting and service agreements

Pursuant to the exclusive technical consulting and service agreements that have been entered into by the WFOEs and the VIEs, the VIEs have engaged the WFOEs as their exclusive provider of technical support and management consulting services. The VIEs shall pay to the WFOEs service fees calculated based on such VIE’s revenues reduced by its value-added taxes and surcharges, operating expenses and an appropriate amount of retained profit that is determined pursuant to our tax planning strategies and relevant tax laws. The service fees can be adjusted by the WFOEs unilaterally. The WFOEs shall exclusively own any intellectual property arising from the performance of this agreement. This agreement has a 30 year term that can be automatically extended for another 10 years at the option of the WFOEs. The agreement can only be terminated mutually by the parties in writing. During the term of the agreement, the VIEs may not enter into any agreement with third parties for the provision of any technical or management consulting services without prior consent of the WFOEs.

Loan agreement

Pursuant to the loan agreements between the Nominee Shareholders of the VIEs and the WFOEs, the WFOEs granted interest-free loans for the Nominee Shareholders’ contributions to the VIEs. The term of the loan is indefinite until the WFOEs requests repayment. The manner and timing of the repayment shall be at the sole discretion of the WFOEs and at the WFOEs’ option may be in the form of transferring the VIEs’ equity interest to the WFOEs or their designated persons.

Exclusive equity option agreements

Pursuant to the exclusive equity option agreements entered into among the Nominee Shareholders of the VIEs, VIEs and the WFOEs, the Nominee Shareholders jointly and severally granted to the WFOEs an option to purchase their equity interests in the VIEs. The purchase price will be offset against the loan repayments under the loan agreements. If the transfer price of the equity interest is greater than the loan amount, the Nominee Shareholders are required to immediately return the received transfer price in excess of the loan amount to the WFOEs or any person designated by the WFOEs. The WFOEs may exercise such option at any time until it has acquired all equity interests of the VIEs or freely transfer the option to any third party and such third party may assume the right and obligations of the option agreement. The exclusive equity option agreements have an indefinite term and will terminate at the earlier of i) the date on which all of the equity interests have been transferred to the WFOEs or any person designated by the WFOEs; or ii) the unilateral termination by the WFOEs.

Equity interest pledge agreements

Pursuant to the equity interest pledge agreements entered into between the Nominee Shareholders of the VIEs and the WFOEs, the Nominee Shareholders pledged all of their equity interests in the VIEs to the WFOEs as collateral for all of their payments due to the WFOEs and to secure their obligations under the above agreements. The Nominee Shareholders may not transfer or assign the shares, the rights and obligations in the share pledge agreement or create or permit to create any pledges which may have an adverse effect on the rights or benefits of the VIEs without the WFOE’s preapproval. The WFOE is entitled to transfer or assign in full or in part the shares pledged. In the event of default, the WFOE as the pledgee will be entitled to request immediate repayment of the loan or to dispose of the pledged equity interests through transfer or assignment. There have been no dividends or distributions from inception to date. The equity interest pledge agreements have an indefinite term and will terminate after all the obligations under these agreements have been satisfied in full or the pledged equity interests have been transferred to the WFOEs or their designees.

Power of attorney agreements

Pursuant to the power of attorney agreements, Shareholders of the VIEs have given the WFOEs an irrevocable proxy to act on their behalf on all matters pertaining to the VIEs and to exercise all of their rights as shareholders of the VIEs, including the right to attend shareholders‘ meetings, to exercise voting rights and to transfer all or a part of his equity interests in the VIEs.

In June 2011, the Contractual Agreements were supplemented with the following terms:

•

With respect to the exclusive equity option agreements, in the event of liquidation or dissolution of the VIEs, all assets shall be sold to the WFOEs at the lowest selling price permitted by applicable PRC law, and any proceeds from the transfer and any residual interests in the VIEs shall be remitted to the WFOEs immediately;

•

With respect to the exclusive equity option agreements, dividends and distributions are not permitted without the prior consent of the WFOEs, to the extent there is a dividend or distribution, the Nominee Shareholders will remit the amounts in full to the WFOEs immediately;

•

With respect to the exclusive technical consulting and service agreements and loan agreements, the WFOEs shall provide the necessary financial support to the VIEs whether or not the VIEs incur any losses, and not request for repayment if the VIEs are unable to do so.

Risk in relation to the VIE Structure

Internet and advertising related businesses are subject to significant restrictions under current PRC laws and regulations. Specifically, foreign investors are not allowed to own more than a 50% equity interest in any Internet Content Provider (“ICP”) business. In addition, PRC regulations require any foreign entities that invest in the advertising services industry to have at least a two-year track record with a principal business in the advertising industry outside of China.

The Group conducts its operations in China through Contractual Agreements entered into between the WFOEs and VIEs. In 2014, the Group began gradually migrating the advertising service business from the VIEs to the subsidiaries of Autohome Media, a transition that was completed to a substantial extent. If the Company or any of its current or future VIEs or subsidiaries are found in violation of any existing or future laws or regulations, or fail to obtain or maintain any of the required permits or approvals, the relevant PRC regulatory authorities would have broad discretion in dealing with such violations, including levying fines, confiscating the income of Autohome WFOE, Chezhiying WFOE and VIEs, revoking their business licenses or operating licenses, shutting down the Group’s servers or blocking the Group’s websites, discontinuing or placing restrictions or onerous conditions on the Group’s operations, requiring the Group to undergo a costly and disruptive restructuring, restricting the Group’s rights to use the proceeds from this offering to finance the Group’s business and operations in China, or enforcement actions that could be harmful to the Group’s business. Any of these actions could cause significant disruption to the Group’s business operations and severely damage the Group’s reputation, which would in turn materially and adversely affect the Group’s business and results of operations. In addition, if the imposition of any of these penalties causes the Company to lose the rights to direct the actives of VIEs or the Company’s right to receive their economic benefits, the Company would no longer be able to consolidate the VIEs.

In addition, if Shanghai Advertising, Guangzhou Advertising, Autohome Information and its subsidiaries, Shengtuo Hongyuan and its subsidiaries or their shareholders fail to perform their obligations under the Contractual Agreements, the Company may have to incur substantial costs and expend resources to enforce the Company’s rights under the contracts. The Company may have to rely on legal remedies under PRC law, including seeking specific performance or injunctive relief and claiming damages, which may not be effective. All of these Contractual Agreements are governed by PRC law and provide for the resolution of disputes through arbitration in the PRC. Accordingly, these contracts would be interpreted in accordance with PRC law and any disputes would be resolved in accordance with PRC legal procedures. The legal system in PRC is not as developed as in other jurisdictions, such as United States. As a result, uncertainties in the PRC legal system could limit the Company’s ability to enforce these Contractual Agreements. Under PRC law, rulings by arbitrators are final, parties cannot appeal the arbitration results in courts, and prevailing parties may only enforce the arbitration awards in PRC courts through arbitration award recognition proceedings, which would incur additional expenses and delay. In the event the Company is unable to enforce these Contractual Agreements, the Company may not be able to exert effective control over its VIEs, and the Company’s ability to conduct its business may be negatively affected.

Based on the advice of the Company’s PRC legal counsel, the corporate structure and Contractual Agreements of the Company’s VIEs and WFOEs in China are in compliance with all existing PRC laws and regulations. Therefore, in the opinion of management, (i) the ownership structure of the Company and the VIEs are in compliance with existing PRC laws and regulations; (ii) the Contractual Agreements with VIEs and their nominee shareholders are valid and binding, and will not result in any violation of PRC laws or regulations currently in effect; and (iii) the Group’s business operations are in compliance with existing PRC law and regulations in all material respects.

VIEs contributed an aggregate of 69.1%, 7.8% and 5.5% of the consolidated net revenues for the years ended December 31, 2014, 2015 and 2016, respectively after elimination of inter-company transactions. As of December 31, 2015 and 2016, the VIEs accounted for an aggregate of 24.1% and 19.3%, respectively, of the consolidated total assets, and 6.2% and 10.5%, respectively, of the consolidated total liabilities after elimination of inter-company balances.

Relevant PRC laws and regulations restrict the VIE from transferring a portion of its net assets to the Company in the form of loans and advances or cash dividends. Please refer to Note 17 for disclosure of restricted net assets.

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

2.	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

(a)

Basis of accounting

The accompanying consolidated financial statements have been prepared in accordance with U.S. Generally Accepted Accounting Principles (“U.S. GAAP”).

(b)

Principles of Consolidation

The consolidated financial statements include the financial statements of the Company, its subsidiaries, and the VIEs for which the Company or subsidiaries of the Company are the primary beneficiaries. All significant inter-company transactions and balances between the Company, its subsidiaries, and the VIEs are eliminated upon consolidation. Results of acquired subsidiaries and VIEs are consolidated from the date on which control is transferred to the Company.

(c)

Use of Estimates

The preparation of the consolidated 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 consolidated financial statements and the reported amounts of revenues and expenses during the year. Areas where management uses subjective judgment include, but are not limited to, estimating the useful lives of long-lived assets and intangible assets, identifying separate accounting units and estimating rebates related to revenue transactions, assessing the initial valuation of the assets acquired and liabilities assumed in a business combination and the subsequent impairment assessment of long-lived assets, intangible assets and goodwill, long-term investments, determining the provision for accounts receivable, inventories and prepayment for vehicle purchase cost, determining the value-added tax (“VAT”) receivables, accounting for deferred income taxes and accounting for the share-based compensation. Changes in facts and circumstances may result in revised estimates. Actual results could differ from those estimates, and as such, differences may be material to the consolidated financial statements.

(d)

Foreign Currency

The functional currency of the Company, its Cayman subsidiaries and Cheerbright, is the United States dollar (“US$”), whereas the functional currency of Hong Kong subsidiaries is the Hong Kong dollar (“HK$”), and the functional currency of the PRC subsidiaries and VIEs is the Chinese Renminbi (“RMB”) as determined based on the criteria of ASC 830, Foreign Currency Matters. The Company uses the RMB as its reporting currency. Transactions denominated in foreign currencies are re-measured into the functional currency at the exchange rates prevailing on the transaction dates. Foreign currency denominated financial assets and liabilities are re-measured at the balance sheet date exchange rate. Exchange gains and losses are included in other income, net in the consolidated statements of comprehensive income.

Assets and liabilities of the Company, its Cayman subsidiaries, Cheerbright and Hong Kong subsidiaries are translated into RMB at fiscal year-end exchange rates. Income and expense items are translated at average exchange rates prevailing during the fiscal year.

(e)

Convenience Translation

Amounts in United States dollars (“US$”) are presented for the convenience of the reader and are translated at the noon buying rate of US$1.00 to RMB6.9430 on December 30, 2016 in the City of New York for cable transfers of RMB as certified for customs purposes by the Federal Reserve Bank of New York. No representation is made that the RMB amounts could have been, or could be, converted into US$ at such rate.

(f)

Cash and Cash Equivalents

Cash and cash equivalents consist of cash on hand, demand deposits, time deposits and money market funds placed with banks or other financial institutions which are unrestricted as to withdrawal and use and have original maturities of three months or less.

(g)

Short-term Investments

Short-term investments represent bank deposits and adjustable-rate financial products with original maturities of greater than 3 months but less than 1 year and are measured at fair value. In accordance with ASC 825, Financial Instruments, for adjustable-rate financial products with the interest rate indexed to performance of underlying assets, the Group elected the fair value method at the date of initial recognition and carried these investments at fair value. Changes in the fair value are reflected in the consolidated statements of comprehensive income as interest income.

(h)

Restricted Cash

Restricted cash represents cash pledged to the bank as collateral for the Company’s notes payable.

(i)

Fair Value Measurements of Financial Instruments

Financial instruments of the Group primarily comprise of cash and cash equivalents, restricted cash, short-term investments, accounts receivable, amounts due from related parties, prepaid expenses and other current assets, other non-current assets, accrued expenses and other payables, notes payable, and amounts due to related parties. The carrying values of these financial instruments approximated their fair values due to the short-term maturity of these instruments.

ASC topic 820 (“ASC 820”), Fair Value Measurements and Disclosures, establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows:

Level 1 – Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets

Level 2 – Include other inputs that are directly or indirectly observable in the marketplace

Level 3 – Unobservable inputs which are supported by little or no market activity

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.

(j)

Accounts Receivable and Allowance for Doubtful Accounts

Accounts receivable are carried at net realizable value. An allowance for doubtful accounts is recorded in the period when a loss is probable based on an assessment of specific evidence indicating troubled collection, historical experience, accounts aging and other factors. An accounts receivable balance is written off after all collection effort has ceased.

(k)

Inventories, net

Inventories consist of new vehicles held for sale, stated at the lower of cost or market value. Cost is determined using the specific identification method. The Company’s purchase arrangements with certain automakers entitle the Company to receive a specified amount of cash rebates if certain conditions are met during the stated rebate periods. The Company accounts for these rebates in accordance with ASC 605-50, Revenue Recognition: Customer Payments and Incentives. Rebates relating to new vehicles purchased but still held by the Company as of the balance sheet date are recorded as a reduction to cost of inventories while rebates relating to new vehicles purchased and sold during the reporting period are recorded as a reduction to cost of revenues.

Adjustments are recorded to write down the cost of inventory to the estimated market value for slow-moving and damaged goods, which is dependent upon factors such as inventory aging, historical and forecasted consumer demand, and promotional environment. Write-downs are recorded in cost of revenues in the consolidated statements of comprehensive income.

(l)

Property and Equipment

Property and equipment are stated at cost and are depreciated using the straight-line method over the estimated useful lives of the assets, as follows:


Category		Estimated useful life
Electronic equipment		3 – 5 years
Office equipment		3 – 5 years
Motor vehicles		4 – 5 years
Purchased and internally-developed software		3 – 5 years
Leasehold improvements		Shorter of lease term or the estimated useful lives of the assets

Repair and maintenance costs are charged to expense as incurred, whereas the costs of betterments that extend the useful life of property and equipment are capitalized as additions to the related assets. Retirements, sale and disposals of assets are recorded by removing the cost and accumulated depreciation with any resulting gain or loss reflected in the consolidated statements of comprehensive income.

(m)

Intangible Assets

Intangible assets are carried at cost less accumulated amortization and any recorded impairment. Intangible assets acquired in a business combination were recognized initially at fair value at the date of acquisition. Intangible assets with finite useful lives are amortized using a straight-line method of amortization that reflects the estimated pattern in which the economic benefits of the intangible asset are to be consumed. The estimated useful life for the intangible assets is as follows:


Category		Estimated useful life
Trademark		3-15 years
Customer relationship		5 years
Websites		4 years
Domain names		4 years
Licensing agreements		1.75 years

(n)

Long-term Investments

The Company’s long-term investments consist of equity method investments. Investments in entities in which the Company can exercise significant influence and holds an investment in voting common stock or in-substance common stock (or both) of the investee 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 investments at cost. The Company subsequently adjusts the carrying amount of the investments to recognize the Company’s proportionate share of each equity investee’s net income or loss into earnings after the date of investments. 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.

(o)

Goodwill

Goodwill represents the excess of the purchase price over the amounts assigned to the fair value of the assets acquired and the liabilities assumed of an acquired business. The Group’s goodwill at December 31, 2015 and 2016 were related to its acquisition of Cheerbright, China Topside and Norstar. In accordance with ASC 350, Goodwill and Other Intangible Assets, recorded goodwill amounts are not amortized, but rather are tested for impairment annually or more frequently if there are indicators of impairment present.

Goodwill is tested for impairment at the reporting unit level on an annual basis (December 31 for the Company) and between annual tests if an event occurs or circumstances change that would more-likely-than-not reduce the fair value of a reporting unit below its carrying value. These events or circumstances include a significant change in stock prices, business environment, legal factors, financial performances, competition, or events affecting the reporting unit. Application of the goodwill impairment test requires judgment, including the identification of reporting units, assignment of assets and liabilities to reporting units, assignment of goodwill to reporting units, and determination of the fair value of each reporting unit. The estimation of fair value of reporting unit using a discounted cash flow methodology also requires significant judgments, including estimation of future cash flows, which is dependent on internal forecasts, estimation of the long-term rate of growth for the Company’s business, estimation of the useful life over which cash flows will occur, and determination of the Company’s weighted average cost of capital. The estimates used to calculate the fair value of a reporting unit change from year to year based on operating results and market conditions. Changes in these estimates and assumptions could materially affect the determination of fair value and goodwill impairment for the reporting unit.

Management has determined that the Group represents the lowest level within the entity at which goodwill is monitored for internal management purposes. Management evaluated the recoverability of goodwill by performing a qualitative assessment before using a two-step impairment test approach at the reporting unit level. Based on an assessment of the qualitative factors, management determined that it is more-likely-than-not that the fair value of the reporting unit is in excess of its carrying amount. Therefore, management concluded that it was not necessary to proceed to the two-step goodwill impairment test. No impairment loss was recorded for any of the years presented.

If the Group reorganizes its reporting structure in a manner that changes the composition of one or more of its reporting units, goodwill is reassigned based on the relative fair value of each of the affected reporting units.

(p)

Impairment of Long-Lived Assets and Intangibles

The Group evaluates its long-lived assets or asset group, including intangible assets with finite lives, for impairment whenever events or changes in circumstances (such as a significant adverse change to market conditions that will impact the future use of the assets) indicate that the carrying amount of an asset or a group of long-lived assets may not be recoverable. When these events occur, the Group evaluates impairment by comparing the carrying amount of the assets to future undiscounted net cash flows expected to result from the use of the assets and their eventual disposition. If the sum of the expected undiscounted cash flow is less than the carrying amount of the assets, the Group would recognize an impairment loss based on the excess of the carrying amount of the asset group over its fair value. No impairment charge was recorded for any of the years presented.

(q)

Revenue Recognition

The Group’s revenue is derived from media services, leads generation services and online marketplace. Revenue is recognized only when the price is fixed or determinable, persuasive evidence of an arrangement exists, the service is performed and collectability of the related fee is reasonably assured based on the guidance in ASC 605, Revenue Recognition.

Contracts are signed to establish significant terms such as the price and services to be provided. The Group considers the price for its services to be fixed and determinable when the Group and its customers have signed the contracts. The Group assesses the creditworthiness of its customers prior to signing the contracts to ensure collectability is reasonably assured. Non-refundable payments received before all of the relevant criteria for revenue recognition are satisfied and are to be recognized ratably over a period are recorded as deferred revenue.

Starting 2016, in order to better present the business, the Group changed its revenue reporting lines into media services, leads generation services and online marketplace, from advertising services and dealer subscription services, with the comparative figures for the years ended December 31, 2014 and 2015 revised accordingly.

Media services

Media services revenues mainly includes revenues from automaker advertising services and regional marketing campaigns conducted by certain automobile brands’ regional offices. The majority of the Group’s online advertising service arrangements involve multiple deliverables such as banner advertisements, links and logos, other media insertions and promotional activities that are delivered over different periods of time.

In determining its best estimated selling price for each deliverable, the Group considered its overall pricing model and objectives, as well as market or competitive conditions that may impact the price at which the Group would transact if the deliverable were sold regularly on a standalone basis. The Group monitors the conditions that affect its determination of selling price for each deliverable and reassesses such estimates periodically. Revenue is recognized ratably when the advertisements are published over the stated display period in the case of websites and mobile applications or when the services have been rendered in the case of promotional activities. The amount recognized is limited to the amount that is not contingent upon the delivery of additional deliverables or meeting other specified performance conditions.

Leads generation services

Leads generation services primarily includes revenues from (i) dealer subscription services, (ii) advertising services sold to individual dealer advertisers, and other value-added services. Under the dealer subscription services, the Group makes available throughout the subscription period a webpage linked to its websites where the dealers can publish information such as the pricing of their products, locations and addresses and other related information. Revenue is recognized ratably as services are provided over the subscription period.

Online marketplace

Online marketplace revenues mainly includes revenues from the new vehicle transaction business, which is composed of direct vehicle sales and commission-based services facilitating transactions on the Autohome Mall platform and other platform-based service fee. For direct vehicle sales, the Company recognizes revenue on a gross basis as it acts as the principal, is the primary obligor of the sales arrangements and is subject to inventory risk. Revenue from direct vehicle sales are recognized when a sales contract has been executed and the vehicle has been delivered. Under the commission-based service arrangements, the Company earns commission for the new vehicle transactions facilitated through the Autohome Mall platform. Commission revenue is recognized after the vehicles are delivered to customers.

Rebates and cash incentives provided to customers

The Group provides rebates to agency companies based on cumulative annual advertising and service volume or surrounding occasional activities. The Group estimates its obligations under such agreements based on an evaluation of the likelihood of the agency companies’ achievement of the advertising and service volume targets, giving consideration to the actual activity during the incentive period and, as appropriate, evaluation of the agency companies’ purchase trends and history.

The Group also provides cash incentives to automakers and dealers who participated in various incentive programs on the Group’s online transaction platform. The cash incentives are accounted for as a reduction of revenue in accordance with ASC 605-50, “Revenue Recognition: Customer Payments and Incentives”. However, for the cash incentives not within the scope of ASC 605-50 and provided to the end users for the promotional purpose, they are recognized as expense.

The Group has estimated and recorded rebates and cash incentives to agency companies, dealers and automakers cumulatively amounting to RMB395,175, RMB578,548 and RMB653,481 (US$94,121) for the years ended December 31, 2014, 2015 and 2016, as a reduction of revenue, respectively.

(r)

Cost of Revenues

Cost of revenues consist primarily of bandwidth and internet data center fees, depreciation of the Group’s long-lived assets, amortization of acquired intangible assets, VAT and surcharges, content-related costs, cost of sales and write-downs of inventories and prepayment for vehicle purchase cost. Content-related costs primarily comprise of salaries and benefits for employees directly involved in revenue generation activities and other overhead expenses directly attributable to the provision of the media services, leads generation services and online marketplace. Cost of sales include vehicle purchase cost and other directly attributable costs. Rebates relating to new vehicles purchased and sold during the reporting period are recorded as a reduction to cost of revenues.

The Group’s business is subject to VAT, surcharges and cultural construction fees levied on advertising related sales in China. Pursuant to ASC 605-45, Revenue Recognition—Principal Agent Considerations, the group elected to present VAT, surcharges and cultural construction fees as cost of revenues on the consolidated statements of comprehensive income. For the years ended December 31, 2014, 2015 and 2016, the Company’s PRC subsidiaries and its VIEs excluding Beijing Prbrownies Software Co., Ltd. and Chengdu Prbrownies Software Co., Ltd. are subject to a 6% VAT for the media services and leads generation services provided and 17% for the direct vehicle sales under online marketplace. For Beijing Prbrownies Software Co., Ltd. and Chengdu Prbrownies Software Co., Ltd., they are entitled to 17% VAT for the dealer subscription services under leads generation services. Since November 2014 and December 2016, respectively, Beijing Prbrownies Software Co., Ltd. and Chengdu Prbrownies Software Co., Ltd. were entitled to a 14% VAT refund on the total VAT payable at the rate of 17% after registration of its software resolutions with the relevant authority.

(s)

Advertising Expenditures

Advertising expenditures which amounted to RMB266,942, RMB533,632 and RMB756,073 (US$108,897) for the years ended December 31, 2014, 2015 and 2016, respectively, are expensed as incurred and are included in sales and marketing expenses.

(t)

Product Development Expenses

Product development expenses consist primarily of employee costs related to personnel involved in the development and enhancement of the Group’s service offerings on its websites and mobile applications. The Group recognizes these costs as expenses when incurred, unless they result in significant additional functionality, in which case they are capitalized.

The Group capitalized certain internally-developed software development costs in accordance with ASC subtopic 350-40 (“ASC 350-40”), Intangibles-Goodwill and Other: Internal-Use Software, amounting to nil, RMB1,326 and RMB6,126 (US$882) for the years ended December 31, 2014, 2015 and 2016, 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 includes salaries and benefits 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 “Property and equipment, net”. The amortization expense for capitalized software costs amounted to nil, RMB93 and RMB1,227 (US$177) for the years ended December 31, 2014, 2015 and 2016, respectively. The unamortized amount of capitalized internal use software development costs was RMB1,233 and RMB6,132 (US$883) as of December 31, 2015 and 2016, respectively.

(u)

Leases

Leases are classified at the inception date as either a capital lease or an operating lease. The Group assesses a lease to be a capital lease if any of the following conditions exist: a) ownership is transferred to the lessee by the end of the lease term, b) there is a bargain purchase option, c) the lease term is at least 75% of the property’s estimated remaining economic life or d) the present value of the minimum lease payments at the beginning of the lease term is 90% or more of the fair value of the leased property to the lessor at the inception date. A capital lease is accounted for as if there was an acquisition of an asset and an incurrence of an obligation at the inception of the lease. The Group has no capital leases for the years presented.

All other leases are accounted for as operating leases wherein rental payments are expensed on a straight-line basis over the periods of their respective lease terms. The Group leases office space and employee accommodation under operating lease agreements. Certain of the lease agreements contain rent holidays. Rent holidays are considered in determining the straight-line rental expense to be recorded over the lease term. The lease term begins on the date of initial possession of the lease property for purposes of recognizing lease expense on straight-line basis over the term of the lease.

(v)

Notes payable

Notes payable represents short-term bank acceptance notes issued by financial institutions that entitle the holder to receive the stated amount from the financial institutions at the maturity date of the notes. The Group has utilized notes payable to settle amounts owed to the automakers.

(w)

Income Taxes

The Group accounts for income taxes using the liability method. Under this method, deferred tax assets and liabilities are determined based on the difference between the financial reporting and tax bases of assets and liabilities using enacted tax rates that will be in effect in the period in which the differences are expected to reverse. The Group records a valuation allowance against deferred tax assets if, based on the weight of available evidence, it is more-likely-than-not that some portion, or all, of the deferred tax assets will not be realized. The effect on deferred taxes of a change in tax rates is recognized in income in the period that includes the enactment date.

The Group applies ASC 740, Accounting for Income Taxes, to account for uncertainty in income taxes. ASC 740 prescribes a recognition threshold a tax position is required to meet before being recognized in the financial statements. The Group has recorded unrecognized tax benefits in the other liabilities line item in the accompanying consolidated balance sheets. The Group has elected to classify interest and penalties related to unrecognized tax benefits, if and when required, as part of “income tax expense”, in the consolidated statements of comprehensive income.

The Group’s estimated liability for unrecognized tax benefits and the related interest and penalties are periodically assessed for adequacy and may be affected by changing interpretations of laws, rulings by tax authorities, changes and/or developments with respect to tax audits, and expiration of the statute of limitations. The actual benefits ultimately realized may differ from the Group’s estimates. As each audit is concluded, adjustments, if any, are recorded in the Company’s consolidated financial statements. Additionally, in future periods, changes in facts and circumstances, and new information may require the Group to adjust the recognition and measurement estimates with regard to individual tax positions. Changes in recognition and measurement estimates are recognized in the period in which they occur.

(x)

Earnings Per Share

Earnings per share are calculated in accordance with ASC 260-10, Earnings per Share: Overall. Basic earnings per share are computed by dividing net income attributable to holders of ordinary shares by the weighted average number of ordinary shares outstanding during the year using the two-class method. Under the two-class method, net income is allocated between the Class A and Class B ordinary shares based on their participating rights in undistributed earnings as if all the earnings for the reporting period had been distributed.

Diluted earnings per ordinary share reflects the potential dilution that could occur if securities to issue ordinary shares were exercised. The dilutive effect of outstanding share-based awards is reflected in the diluted earnings per share by application of the treasury stock method. The computation of the dilutive net income per share of Class A ordinary share assumes the conversion of Class B ordinary shares, while the diluted income per share of Class B ordinary share does not assume the conversion of those shares.

The participating rights (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 and conversion. As a result, and in accordance with ASC 260, the undistributed income for each year is allocated based on the contractual participating rights of the Class A and Class B ordinary shares as if the income for the year had been distributed. As the participating rights are identical, the undistributed income is allocated on a proportionate basis.

(y)

Comprehensive Income

Comprehensive income is defined to include all changes in shareholders’ equity except those resulting from investments by owners and distributions to owners. Among other disclosures, ASC 220-10, Comprehensive Income: Overall requires that all items that are required to be recognized under current accounting standards as components of comprehensive income be reported in a financial statement that is displayed with the same prominence as other financial statements. For each of the periods presented, the Company’s comprehensive income includes foreign currency translation adjustments and is presented in the consolidated statement of comprehensive income. There have been no reclassifications out of accumulated other comprehensive income to net income for the years presented.

(z)

Noncontrolling interests

Noncontrolling interests are recognized to reflect the portion of the equity of majority-owned subsidiary which is not attributable, directly or indirectly, to the controlling shareholder. Non-controlling interests are classified as a separate line item in the equity section of the Group’s consolidated balance sheets and have been separately disclosed in the Group’s consolidated statements of comprehensive income to distinguish the interests from that of the Company.

(aa)

Segment Reporting

In accordance with ASC 280-10, Segment Reporting: Overall, the Group’s chief operating decision maker has been identified as the Chief Executive Officer who reviews the consolidated results of operations when making decisions about allocating resources and assessing performance of the Group as a whole; hence, the Group has only one operating segment. The Group does not distinguish between markets or segments for the purpose of internal reporting. As the Group’s long-lived assets and revenue are substantially located in and derived from the PRC, no geographical segments are presented.

(bb)

Employee Benefits

The full-time employees of the Company’s PRC subsidiaries and VIEs are entitled to staff welfare benefits including medical care, housing fund, pension benefits and unemployment insurance, which are governmental mandated defined contribution plans. These entities are required to accrue for these benefits based on certain percentages of the employees’ respective salaries, subject to certain ceilings, in accordance with the relevant PRC regulations, and make cash contributions to the state-sponsored plans out of the amounts accrued. The total expenses for the employee benefits plans were RMB61,532, RMB134,125 and RMB214,596 (US$30,908) for the years ended December 31, 2014, 2015 and 2016, respectively.

(cc)

Share-based Compensation

Share-based awards granted to employees are accounted for under ASC 718, Compensation—Stock Compensation, which requires that share-based awards granted to employees be measured based on the grant date fair value and recognized as compensation expense over the requisite service period (which is generally the vesting period) in the consolidated statements of comprehensive income. The Company has elected to recognize compensation expense using the straight-line method for all share-based awards granted with service conditions that have a graded vesting schedule. ASC 718 requires forfeitures to be estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from initial estimates.

Forfeiture rates are estimated based on historical and future expectations of employee turnover rates and are adjusted to reflect future changes in circumstances and facts, if any. Share-based compensation expense is recorded net of estimated forfeitures such that expense is recorded only for those share-based awards that are expected to vest. To the extent the Company revises these estimates in the future, the share-based payments could be materially impacted in the period of revision, as well as in following periods. The Company, with the assistance of an independent third-party valuation firm, determined the fair value of the stock options granted to employees. The binomial option pricing model was applied in determining the estimated fair value of the options granted to employees. Subsequent to the IPO, fair value of the ordinary shares is the price of the Company’s publicly traded shares.

The Company accounts for a change in any of the terms or conditions of share-based awards as a modification in accordance with ASC subtopic 718-20, Compensation-Stock Compensation: Awards Classified as Equity, whereby the incremental fair value, if any, of a modified award, is recorded as compensation cost on the date of modification for vested awards or over the remaining vesting period for unvested awards. The incremental compensation cost is the excess of the fair value of the modified award on the date of modification over the fair value of the original award immediately before the modification.

(dd)

Government Grants

Government grants primarily represent tax refunds for operating a business in certain jurisdictions and fulfilment of specified tax payment obligations, and subsidies. These grants are not subject to any specific requirements and are recorded when received in “other income, net” in the Company’s consolidated statements of comprehensive income. For the years ended December 31, 2014, 2015 and 2016, RMB2,984, RMB11,281 and RMB12,576 (US$1,811) of government grants were recorded as other income, net.

Recent Accounting Pronouncements

In July 2015, the FASB issued ASU No. 2015-11, Simplifying the Measurement of Inventory (“ASU 2015-11”). The amendments in this update simplify the measurement of inventory. ASU 2015-11 states that an entity should measure inventory at the lower of cost and net realizable value. The amendments in ASU 2015-11 are effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. The amendments in ASU 2015-11 should be applied prospectively with earlier application permitted as of the beginning of an interim or annual reporting period. The adoption of the guidance is not expected to have significant impact on the Company’s consolidated financial statements.

In August 2015, the FASB issued ASU No. 2015-14, Revenue from Contracts with Customers-Deferral of the effective date (“ASU 2015-14”). The amendments in ASU 2015-14 defer the effective date of ASU No. 2014-09, Revenue from Contracts with Customers issued in May 2014. Further in 2016, as a clarification of the new revenue guidance, the FASB issued ASU No. 2016-08, Revenue from Contracts with Customers—Principal versus Agent Considerations (Reporting Revenue Gross versus Net) (“ASU 2016-08”), ASU No. 2016-10, Revenue from Contracts with Customers—Identifying Performance Obligations and Licensing (“ASU 2016-10”), ASU No. 2016-12, Revenue from Contracts with Customers—Narrow-Scope Improvements and Practical Expedients (“ASU 2016-12”), and ASU No. 2016-20, Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers (“ASU 2016-20”). The amendments in ASU 2016-08, ASU 2016-10, ASU 2016-12 and ASU 2016-20 do not change the core principle of the guidance. All the above amendments regarding the new revenue guidance are effective for annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. Earlier application is permitted only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period. The Company will apply the new revenue guidance beginning January 1, 2018 and will not early adopt. The Company has set up a revenue project team and is in the process of evaluating the contracts of each revenue stream to determine the impact on the Company’s consolidated financial statements. The Company plans to continue the evaluation, analysis, and documentation of its adoption of ASU 2014-09 (including those subsequently issued updates that clarify ASU 2014-09’s provisions) throughout 2017 and finalize determination of the impact that the adoption will have on its consolidated financial statements under the new standard.

In November 2015, the FASB issued ASU No. 2015-17, Income Taxes-Balance Sheet Classification of Deferred Taxes (“ASU 2015-17”). The amendments in this update simplify the presentation of deferred income taxes. ASU 2015-17 requires that deferred tax liabilities and assets be classified as noncurrent in a classified statement of financial position. The amendments in ASU 2015-17 are effective for fiscal years beginning after December 15, 2016 including interim periods within those fiscal years. Earlier application is permitted for all entities as of the beginning of an interim or annual reporting period. The amendments in this Update may be applied either prospectively to all deferred tax liabilities and assets or retrospectively to all periods presented. The Company will adopt the guidance on a retrospective basis starting from the first quarter of 2017 and present all the deferred tax assets and liabilities as non-current items on the Company’s consolidated balance sheets, including comparative periods.

In February 2016, the FASB issued ASU No. 2016-02, Leases (“ASU 2016-02”). Under the new provisions, all lessees will report a right-of-use asset and a liability for the obligation to make payments for all leases with the exception of those leases with a term of 12 months or less. All other leases will fall into one of two categories: (i) financing leases, similar to capital leases, which will require the recognition of an asset and liability, measured at the present value of the lease payments and (ii) operating leases which will require the recognition of an asset and liability measured at the present value of the lease payments. Lessor accounting remains substantially unchanged with the exception that no leases entered into after the effective date will be classified as leveraged leases. For sale leaseback transactions, the sale will only be recognized if the criteria in the new revenue recognition standard are met. It is expected to be effective for fiscal years and interim periods beginning after December 15, 2018 for public entities. Early application is permitted. The Company is currently evaluating the impact of adopting this guidance.

In March 2016, the FASB issued ASU No. 2016-09, Compensation—Stock Compensation: Improvements to Employee Share-Based Payment Accounting (“ASU 2016-09”). The amendments in ASU 2016-09 simplify the several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, forfeitures, and classification on the statement of cash flows. The amendments in ASU 2016-09 are effective for annual periods beginning after December 15, 2016, and interim periods within those annual periods. The adoption of the guidance is not expected to have significant impact on the Company’s consolidated financial statements.

In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows: Classification of Certain Cash Receipts and Cash Payments (“ASU 2016-15”). The amendments in ASU 2016-15 address eight specific cash flow issues with the objective of reducing the existing diversity in practice. The amendments in ASU 2016-15 are effective for annual periods beginning after December 15, 2017, and interim periods within those annual periods. The adoption of the guidance is not expected to have significant impact on the Company’s consolidated financial statements.

In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows (Topic 320): Restricted Cash (“ASU 2016-18”). The amendments in ASU 2016-18 require that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The amendments in ASU 2016-18 are effective for annual periods beginning after December 15, 2017, and interim periods within those annual periods. The adoption of the guidance is not expected to have significant impact on the Company’s consolidated financial statements.

(ff)

Concentration of Risk

Credit risk

Financial instruments that potentially subject the Group to significant concentrations of credit risk consist primarily of cash and cash equivalents, restricted cash, short-term investments and accounts receivable. As of December 31, 2015 and 2016, cash and cash equivalents, restricted cash and short-term investments altogether amounting to RMB4,169,053 and RMB5,733,321 (US$825,770), respectively, were deposited with various major reputable financial institutions located in the PRC and international financial institutions outside of the PRC. Management believes that these financial institutions are of high credit quality and continually monitors the creditworthiness of these financial institutions. Historically, deposits in Chinese banks are secure due to the state policy on protecting depositors’ interests. However, China promulgated a new Bankruptcy Law in August 2006 that came into effect on June 1, 2007, which contains a separate article expressly stating that the State Council may promulgate implementation measures for the bankruptcy of Chinese banks based on the Bankruptcy Law. Under the new Bankruptcy Law, a Chinese bank may go into bankruptcy. In the event of bankruptcy of one of the banks which holds the Group’s deposits, it is unlikely to claim its deposits back in full since it is unlikely to be classified as a secured creditor based on PRC laws. The Group continues to monitor the financial strength of these financial institutions.

Accounts receivable are typically unsecured and derived from revenue earned from customers in the PRC, which are exposed to credit risk. The risk is mitigated by the Group’s assessment of its customers’ creditworthiness and its ongoing monitoring process of outstanding balances. The Group maintains reserves for estimated credit losses and these losses have generally been within expectations. There were both two customers that individually represented greater than 10% of the total accounts receivable as of December 31, 2015 and 2016.

Business, customer, political, social and economic risks

The Group 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 Group’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; acceptance of the Internet as an effective marketing platform by China’s automotive industry; changes in certain strategic relationships or customer relationships; growth in China’s automotive industry, regulatory considerations; and risks associated with the Group’s ability to attract and retain employees necessary to support its growth.

There were no customers that individually represented greater than 10% of the total net revenues for the years ended December 31, 2014, 2015 and 2016, respectively.

Currency convertibility risk

The Group transacts substantially all its business in RMB, which is not freely convertible into foreign currencies. On January 1, 1994, the PRC government abolished the dual-rate system and introduced a single rate of exchange as quoted daily by the People’s Bank of China (the “PBOC”). However, the unification of the exchange rates does not imply that the RMB may be readily convertible into US$ or other foreign currencies. All foreign exchange transactions continue to take place either through the PBOC or other banks authorized to buy and sell foreign currencies at the exchange rates quoted by the PBOC. Approval of foreign currency payments by the PBOC or other institutions requires submitting a payment application form together with suppliers’ invoices, shipping documents and signed contracts.

As of December 31, 2016, cash and cash equivalents, restricted cash and short-term investments in PRC were held by PRC subsidiaries and the VIEs. Cash and cash equivalents, restricted cash and short-term investments of PRC subsidiaries and VIEs are all denominated in RMB and altogether amounted to RMB4,746,982 (US$683,708) and RMB58,123 (US$8,371), respectively. Cash distributed outside of the PRC by PRC subsidiaries and the VIEs may be subject to PRC dividend withholding tax.

Foreign Currency exchange rate risk

Since July 21, 2005, the RMB was permitted to fluctuate within a narrow and managed band against a basket of certain foreign currencies. There was depreciation of 2.4%, 4.2% and 6.7% in the year ended December 31, 2014, 2015 and 2016, respectively. A significant depreciation of the RMB against the U.S. dollar may significantly reduce the U.S. dollar equivalent of the Company’s earnings, which in turn could adversely affect the price of the Company’s ADSs.

Other financial instruments

The followings are other financial instruments not measured at fair value in the consolidated balance sheets, but for which the fair value is estimated for disclosure purposes.

Financial assets including accounts receivable, amounts due from related parties, prepaid expenses and other current assets, and other non-current assets are not measured at fair value in the consolidated balance sheets, and the carrying values approximated fair value due to their short-term maturity. Financial liabilities including notes payable, accrued expense and other payables, and amounts due to related parties are also not measured at fair value in the consolidated balance sheets, and the carrying values approximated fair value due to their short-term maturity.

Assets and liabilities measured at fair value on a nonrecurring basis

The Group measures certain assets, including long-term investments, goodwill and intangible assets, at fair value on a nonrecurring basis when they are deemed to be impaired (Level 3). The fair values of these assets are determined based on valuation techniques using the best information available, and may include management judgments, future performance projections, etc. An impairment charge to these investments is recorded when the cost of the investment exceeds its fair value and this condition is determined to be other-than-temporary.

Enterprise income tax

Cayman Islands

The Company is incorporated in the Cayman Islands and conducts substantially all of its business through its PRC subsidiaries and VIEs. Under the current laws of the Cayman Islands, the Company is not subject to tax on income or capital gains. In addition, upon payments of dividends by these entities to their shareholders, no Cayman Islands withholding tax will be imposed.

British Virgin Islands

Under the current laws of the British Virgin Islands, Cheerbright is not subject to tax on income or capital gains. In addition, upon payments of dividends by these entities to their shareholders, no British Virgin Islands withholding tax will be imposed.

Hong Kong

Autohome HK is incorporated in Hong Kong on March 16, 2012. In October 2013, Autohome HK acquired Autohome Media, a Hong Kong advertising and marketing company. Also in 2015, three new entities are established in Hong Kong. Companies registered in Hong Kong are subject to Hong Kong Profits Tax on the taxable income as reported in their respective statutory financial statements adjusted in accordance with relevant Hong Kong tax laws. The applicable tax rate is 16.5% in Hong Kong. For the years ended December 31, 2014, 2015 and 2016, the Company did not make any provisions for Hong Kong profit tax as there were no assessable profits derived from or earned in Hong Kong during this period. Under the Hong Kong tax law, subsidiaries in Hong Kong are exempted from income tax on its foreign-derived income and there are no withholding taxes in Hong Kong on remittance of dividends.

The PRC

In September 2010, Autohome WFOE was recognized as a “High-New Technology Enterprise” (“HNTE”), and is eligible for a 15% preferential tax rate effective from 2010 to 2015 including the renewal period of three years. In December 2016, Autohome WFOE successfully reapplied for the HNTE and obtained the HNTE certificate, enabling Autohome WFOE to continue to enjoy 15% preferential tax rate from 2016 to 2018. In July 2015, Beijing Autohome Technologies Co., Ltd. obtained the certificate of HNTE and is eligible for a 15% preferential tax rate from 2015 to 2017. Beijing Prbrownies was recognized as an HNTE in February 2016, qualifying it for the preferential 15% enterprise income tax rate from 2015 to 2017. Besides being an HNTE, Beijing Prbrownies was also a software enterprise. Pursuant to the Circular on Issues concerning Preferential Enterprise Income Tax Policies for Software and Integrated Circuit Industries in May 2016, the eligible software enterprises would enjoy preferential tax rate policy, whereby the enterprise will be entitled to two-year enterprise income tax exemption and reduced enterprise income tax rate of 12.5% for the three years thereafter, depending on the results of annual tax filing and examination afterwards instead of pre-approval process. Beijing Prbrownies started to make profit since 2015, and it passed the tax filing and examination as an eligible software enterprise by the relevant tax authorities in 2016, qualifying it for the exemption of enterprise income tax for the year 2015. A reversal of RMB173,557 (US$24,997) was recorded in 2016 for the change in enacted tax rate, composed of current income tax expense of RMB181,586 (US$26,153) and deferred income tax expense of RMB8,029 (US$1,156 ). For the tax year of 2016, 15% preferential tax rate of HNTE was applied for Beijing Prbrownies in accrual of income tax expense, considering that the uncertainty in the results of tax filing and examination was not eliminated yet. The aggregate effects of the preferential tax rate were RMB89,394, RMB56,389 and RMB330,198 (US$47,558) for the years ended December 31, 2014, 2015 and 2016, respectively. The basic earnings per share effects related to the preferential tax rate were RMB0.84, RMB0.50 and RMB2.89 (US$0.42) for the years ended December 31, 2014, 2015 and 2016, respectively.

The Company’s remaining PRC subsidiaries and all the VIEs were subject to Enterprise Income Tax (“EIT”) at a rate of 25% for the years ended December 31, 2014, 2015 and 2016.

Under the New EIT Law, dividends paid by PRC enterprises out of profits earned post-2007 to non-PRC tax resident investors are subject to PRC withholding tax of 10%. A lower withholding tax rate may be applied based on applicable tax treaty with certain countries.

The New EIT Law also provides that enterprises established under the laws of foreign countries or regions and whose “place of effective management” is located within the PRC are considered PRC tax resident enterprises and subject to PRC income tax at the rate of 25% on worldwide income. The definition of “place of effective management” refers to an establishment that exercises, in substance, overall management and control over the production and business, personnel, accounting, properties, and other aspects of an enterprise. As of December 31, 2016, no detailed interpretation or guidance has been issued to define “place of effective management”. Furthermore, as of December 31, 2016, the administrative practice associated with interpreting and applying the concept of “place of effective management” is unclear. If the Company is deemed as a PRC tax resident, it would be subject to PRC tax under the New EIT Law. The Company has analyzed the applicability of this law and believes that the chance of being recognized as a tax resident enterprise is remote for PRC tax purposes. .

The Company had minimal operations in jurisdictions other than the PRC. Income/(loss) before income tax expense consists of:

In assessing the realizability of deferred tax assets, the Group has considered whether it is more-likely-than-not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. The Group records a valuation allowance to reduce deferred tax assets to a net amount that management believes is more-likely-than-not of being realizable based on the weight of all available evidence. The Company recorded valuation allowances against the deferred tax assets of eleven and thirteen PRC subsidiaries and VIEs as of December 31, 2015 and 2016, respectively, due to the cumulative tax loss positions and insufficient forecasted future taxable income.

As of December 31, 2016, the Group had net operating losses of approximately RMB335,764 (US$48,360), which can be carried forward to offset taxable income. The net operating loss will start to expire in 2017 if not utilized.

As of December 31, 2015 and 2016, the Company intended to indefinitely reinvest the undistributed earnings of its PRC subsidiaries. As of December 31, 2015 and 2016, the total amount of undistributed earnings from the Company’s PRC subsidiaries that are considered to be permanently reinvested was RMB2,330,698 and RMB3,616,426 (US$520,874), respectively. As of December 31, 2015 and 2016, determination of the amount of unrecognized deferred tax liability related to the earnings that are indefinitely reinvested is not practical.

Unrecognized tax benefits

As of December 31, 2015 and 2016, the Company recorded an unrecognized tax benefit of RMB32,596 and RMB34,977 (US$5,038), respectively, of which nil and nil, respectively, are presented on a net basis against the deferred tax assets related to tax loss carry forwards on the consolidated balance sheets. This represents the difference between the amount of benefit recognized in the statement of financial position and the amount taken or expected to be taken in a tax return. It is possible that the amount of uncertain tax position will change in the next twelve months, however, an estimate of the range of the possible outcomes cannot be made at this time. As of December 31, 2015 and 2016, unrecognized tax benefits of RMB19,951 and RMB19,850 (US$2,859), respectively, if ultimately recognized, will impact the effective tax rate.

A roll-forward of unrecognized tax benefits is as follows:


	December 31,
	2015		2016
	RMB		RMB			US$
Beginning balance		17,274		22,003			3,169

Decreases based on tax positions related to prior years		—		(101	)		(15	)

Ending balance		22,003		21,902			3,154

During the years ended December 31, 2014, 2015 and 2016, the Company recorded late payment interest expense of RMB3,984, RMB3,809 and RMB2,482 (US$357), and penalties of nil, nil and nil, respectively, as part of income tax expense. As of December 31, 2015 and 2016, the Company recorded RMB10,593 and RMB13,075 (US$1,884) for late payment interest expense, and nil and nil for penalties.

The tax years ended December 31, 2012 through 2016 for the Company’s PRC subsidiaries and VIEs remain subject to examination by the PRC tax authorities.

COMMITMENTS AND CONTINGENCIES

Operating lease commitments

The Group leases office space and employee accommodation in the PRC under non-cancellable operating leases expiring on various dates. Payments under operating leases are expensed on a straight-line basis, after considering rent holidays, over the periods of the respective lease terms. The terms of the leases do not contain rent escalation or contingent rents, and for the years ended December 31, 2014, 2015 and 2016, total rental expenses for all operating leases amounted to RMB30,461, RMB49,892 and RMB84,673 (US$12,195) respectively.

As of December 31, 2016, the Group has future minimum lease payments under non-cancellable operating leases, with initial terms in excess of one year, for office premises consisting of the following:

Taxation

As of December 31, 2015 and 2016, the Group has recognized liabilities of RMB32,596 and RMB34,977 (US$5,038), respectively, related to unrecognized tax benefits (Note 7). The final outcome of the tax uncertainty is dependent upon various matters including tax examinations, interpretation of tax laws or expiration of statutes of limitation. However, due to the uncertainties associated with the status of examinations, including the protocols of finalizing audits by the relevant tax authorities, there is a high degree of uncertainty regarding the future cash outflows associated with these tax uncertainties. The Group classified the accrual for unrecognized tax benefits as a non-current liability.

ORDINARY SHARES

Upon the effectiveness of the IPO registration statement, the Company’s ordinary shares were redeemed and cancelled in consideration for the issuance of an equivalent number of Class A ordinary shares and Class B ordinary shares to the holders of former ordinary shares, respectively. Holders of Class A ordinary shares and Class B ordinary shares have the same rights except for conversion and voting rights. Each Class B ordinary share is convertible into one Class A ordinary share at any time, while Class A ordinary shares cannot be converted into Class B ordinary shares under any circumstances. Each Class A ordinary share is entitled to one vote.

Immediately prior to the completion of the IPO in December 2013, the Company had 27,354,496 Class A ordinary shares and 68,788,940 Class B ordinary shares outstanding. During the IPO, the Company issued 8,993,000 Class A ordinary shares. As of December 31, 2013, the Company had ordinary shares outstanding comprised of 36,347,496 Class A ordinary shares and 68,788,940 Class B ordinary shares.

Upon the completion of follow-on offering in November, 2014, 2,424,801 ADSs were issued by the Company and the net proceeds from the follow-on offering amounts to US$97,344 net of issuance costs.

Restricted Net Assets

RESTRICTED NET ASSETS

The Company’s ability to pay dividends is primarily dependent on the Company receiving distributions of funds from its subsidiaries. Relevant PRC statutory laws and regulations permit payments of dividends by the Company’s PRC subsidiaries only out of its retained earnings, if any, as determined in accordance with PRC accounting standards and regulations. The results of operations reflected in the consolidated financial statements prepared in accordance with U.S.GAAP differ from those reflected in the statutory financial statements of the Company’s PRC subsidiaries.

Under PRC law, the Company’s PRC subsidiaries are required to provide for certain statutory reserves, namely a general reserve, an enterprise expansion fund and a staff welfare and bonus fund. The subsidiary is required to allocate at least 10% of their after tax profits on an individual company basis as determined under PRC accounting standards to the general reserve and has the right to discontinue allocations to the general reserve if such reserve has reached 50% of registered capital on an individual company basis. In addition, the registered capital of the Company’s PRC subsidiaries and VIEs is also restricted.

Appropriations to the enterprise expansion fund and staff welfare and bonus fund are at the discretion of the Board of Directors of the subsidiary. The Company’s VIEs in the PRC are also subject to similar statutory reserve requirements. These reserves can only be used for specific purposes and are not transferable to the Group in the form of loans, advances or cash dividends. As of December 31, 2014, 2015 and 2016, the Company’s PRC subsidiaries and VIEs had appropriated RMB8,836, RMB19,175 and RMB36,000 (US$5,185), respectively, of retained earnings for its statutory reserves.

As a result of these PRC laws and regulations subject to the limit discussed above that require annual appropriations of 10% of after-tax income to be set aside, prior to payment of dividends as general reserve fund, the Company’s PRC subsidiaries and VIEs are restricted in their ability to transfer a portion of their net assets to the Company. Foreign exchange and other regulations in the PRC may further restrict the Company’s PRC subsidiaries and VIEs from transferring funds to the Company in the form of dividends, loans and advances. As of December 31, 2015 and 2016, amounts restricted are the net assets of the Company’s PRC subsidiaries and VIEs, which amounted to RMB3,740,507 and RMB5,165,673 (US$744,012), respectively.

The Company performed a test on the restricted net assets of its consolidated subsidiaries and VIEs in accordance with Securities and Exchange Commission Regulation S-X Rule 4-08 (e)(3), “General Notes to the Financial Statements” and concluded that it was applicable for the Company to disclose the condensed financial information for the parent company (Note 20) for the year ended December 31, 2016. For the purposes of presenting parent only financial information, the Company records its investments in its subsidiaries and VIEs under the equity method of accounting. Such investments are presented on the separate condensed balance sheets of the Company as “Investments in subsidiaries and VIEs” and the profit of the subsidiaries and VIEs is included in “Share of income of subsidiaries and VIEs” in the condensed statements of comprehensive income.

SHARE-BASED COMPENSATION

In order to provide additional incentives to employees and to promote the success of the Company’s business, the Company adopted a share incentive plan in 2011 (the “2011 Plan”) and a share incentive plan in 2013 (the “2013 Plan”), Amended and Restated 2016 Share Incentive Plan (the “2016 Plan”) and 2016 share incentive plan II (the “2016 Plan II”) in 2016, collectively “the Plans”. The Company may grant share-based awards to its employees, directors and consultants to purchase an aggregate of no more than 7,843,100, 3,350,000, 4,890,000 and 3,000,000 ordinary shares of the Company under the 2011 Plan, 2013 Plan, 2016 Plan and 2016 Plan II, respectively. 2011 Plan, 2013 Plan, 2016 Plan and 2016 Plan II were approved by the Board of Directors in May 2011, November 2013, March 2017 and December 2016, respectively. The Plans are administered by the Board of Directors or any of its committees as set forth in the Plans. For share options and restricted shares granted under the Plans, majority are subject to vesting schedules of approximately four years with 25% of the awards vesting each year and have a contractual term of ten years.

Share options

The following table summarizes the Company’s employee share option activity under the share option plans:


	Number of options			Weighted average exercise price		Weighted average grant date fair value		Weighted average remaining contractual term		Aggregate intrinsic value
				US$		US$		Years		US$
Outstanding, January 1, 2016		2,595,065			2.20		5.00		6.21		84,911
Granted		4,742,500			23.85		14.62
Exercised		(1,632,223	)		2.20
Forfeited		(2,883,750	)		23.66

Outstanding, December 31, 2016		2,821,592			16.66		11.87		8.15		24,329

Vested and expected to vest at December 31, 2016		2,739,893			16.48		11.79		8.12		24,102

Exercisable as of December 31, 2016		735,609			2.20		4.93		5.24		16,978

The aggregate intrinsic value in the table above is calculated as the difference between the exercise price of the underlying awards and US$25.28, the closing stock price of the Company’s ordinary shares on December 31, 2016. The weighted-average grant-date fair value of options granted during the years ended December 31, 2014, 2015 and 2016 was US$34.57, nil and US$14.62, respectively. The total grant date fair value of options vested during the years ended December 31, 2014, 2015 and 2016 was RMB29,968, RMB37,582 and RMB25,168 (US$3,625), respectively. Total intrinsic value of options exercised during the years ended December 31, 2014, 2015 and 2016 was RMB693,878, RMB623,605 and RMB246,754(US$35,540), respectively.

The aggregate fair value of the outstanding options at the grant dates were determined to be RMB232,528 (US$33,491) and such amount shall be recognized as compensation expenses using the straight-line method for all employee share options granted with graded vesting. As of December 31, 2016, there was RMB160,640 (US$23,137) of total unrecognized share-based compensation expenses, net of estimated forfeitures, related to unvested share-based awards which are expected to be recognized over a weighted-average period of 3.30 years. Total unrecognized compensation expenses may be adjusted for future changes in estimated forfeitures.

Restricted shares

Restricted shares activity for the year ended December 31, 2016 was as follows:


	Number of shares			Weighted average grant date fair value
				US$
Outstanding, January 1, 2016		1,743,569			32.54
Granted		1,530,972			22.30
Vested		(610,431	)		31.11
Forfeited		(576,718	)		28.32

Outstanding, December 31, 2016		2,087,392			26.61

Expected to vest, December 31, 2016		2,006,935			26.66

The weighted average grant-date fair value of restricted shares granted during the years ended December 31, 2014, 2015 and 2016 was US$37.30, US$34.70 and US$22.30, respectively, which was derived from the fair value of the underlying ordinary shares. The total grant date fair value of restricted shares vested during the years ended December 31, 2014, 2015 and 2016 was RMB7,925, RMB38,104 and RMB131,861 (US$18,992). The aggregate fair value of the outstanding restricted shares at the grant dates were determined to be RMB385,656 (US$55,546) and such amount shall be recognized as compensation expense using the straight-line method for all restricted shares granted with graded vesting. As of December 31, 2016, there was RMB267,389 (US$38,512) of total unrecognized share-based compensation expenses, net of estimated forfeitures, related to unvested restricted shares which are expected to be recognized over a weighted-average period of 2.82 years. Total unrecognized compensation expenses may be adjusted for future changes in estimated forfeitures.

The binomial option pricing model was applied in determining the estimated fair value of the options granted to employees. The model requires the input of highly subjective assumptions including the estimated expected stock price volatility and the exercise multiple for which employees are likely to exercise share options. For expected volatilities, the Company has made reference to the historical price volatilities of ordinary shares of several comparable companies in the same industry as the Company. The exercise multiple is estimated as the ratio of fair value of underlying shares over the exercise price as at the time the option is exercised and is based on a consideration of research study regarding exercise pattern based on historical statistical data. The risk-free rate for periods within the contractual life of the option is based on the U.S. Treasury Bills yield curve in effect at the time of grant. The estimated fair value of the ordinary shares, at the option grant dates prior to the IPO, was determined with assistance from an independent third party valuation firm. The Company’s management is ultimately responsible for the determination of the estimated fair value of its ordinary shares. Subsequent to the IPO, fair value of the ordinary shares was the price of the Company’s publicly traded shares.

In November 2016, the Company approved the vesting acceleration plan of options and restricted shares for certain employees and incremental compensation cost of RMB53,896 (US$7,763) occurred as a result of the modification.

The Company calculated the estimated fair value of the share-based awards on the respective grant dates using the binomial option pricing model with the following assumptions:


	2014	2016
Fair value of ordinary share	US$36.62	US$23.76- US$24.88
Risk-free interest rates	2.909%	1.70%-1.75%
Expected exercise multiple	2.2	2.2-2.8
Expected volatility	53.5%	63%
Expected dividend yield	0.00%	0.00%
Weighted average fair value per option granted	US$34.52-US$34.59	US$14.12- US$15.26

Share-based compensation expenses relating to options and restricted shares granted to employees recognized for the year ended December 31, 2014, 2015 and 2016 is as follows:


	Year ended December 31,
	2014		2015		2016

- Definition

Cash includes currency on hand as well as demand deposits with banks or financial institutions. It also includes other kinds of accounts that have the general characteristics of demand deposits in that the customer may deposit additional funds at any time and effectively may withdraw funds at any time without prior notice or penalty. Cash equivalents, excluding items classified as marketable securities, include short-term, highly liquid Investments that are both readily convertible to known amounts of cash, and so near their maturity that they present minimal risk of changes in value because of changes in interest rates. Generally, only investments with original maturities of three months or less qualify under that definition. Original maturity means original maturity to the entity holding the investment. For example, both a three-month US Treasury bill and a three-year Treasury note purchased three months from maturity qualify as cash equivalents. However, a Treasury note purchased three years ago does not become a cash equivalent when its remaining maturity is three months. Short-term investments, exclusive of cash equivalents, generally consist of marketable securities intended to be sold within one year (or the normal operating cycle if longer) and may include trading securities, available-for-sale securities, or held-to-maturity securities (if maturing within one year), as applicable.
