Basis of presentation

The accompanying unaudited interim condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("US GAAP").

In the opinion of the Company's management, the accompanying unaudited condensed consolidated financial statements contain all normal recurring adjustments necessary for a fair statement of the Company's interim condensed consolidated financial statements as of June 30, 2016 and for the six months ended June 30 2015 and 2016. The year-end condensed balance sheet data as of December 31, 2015 was derived from audited financial statements, but does not include all disclosures required by US GAAP.

The preparation of financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosures of contingent assets and liabilities at the balance sheet dates and the reported amounts of revenues and expenses during the reporting periods.

These unaudited condensed consolidated financial statements should be read in conjunction with the Company's audited financial statements included in the Company's Annual Report on Form 20-F for the year ended December 31, 2015, previously filed with the Securities and Exchange Commission ("SEC").

Consolidation

The unaudited interim condensed consolidated financial statements include the financial statements of the Company, its subsidiaries, VIEs and VIEs' subsidiaries. All significant transactions and balances between the Company, its subsidiaries, VIEs and VIEs' subsidiaries have been eliminated upon consolidation.

A subsidiary is an entity in which the Company, directly or indirectly, controls more than one half of the voting power; has the power to appoint or remove the majority of the members of the board of directors; to cast a majority of votes at the meeting of the board of directors or to govern the financial and operating policies of the investee under a statute or agreement among the shareholders or equity holders.

The Company applies the guidance codified in Accounting Standard Codification 810, Consolidations ("ASC 810") on accounting for VIEs and their respective subsidiaries, which requires certain variable interest entities to be consolidated by the primary beneficiary of the entity in which it has a controlling financial interest. A VIE is an entity with one or more of the following characteristics: (a) the total equity investment at risk is not sufficient to permit the entity to finance its activities without additional financial support; (b) as a group, the holders of the equity investment at risk lack the ability to make certain decisions, the obligation to absorb expected losses or the right to receive expected residual returns, or (c) an equity investor has voting rights that are disproportionate to its economic interest and substantially all of the entity's activities are on behalf of the investor. Accordingly, the financial statements of the following VIEs and VIEs' subsidiaries are consolidated into the Company's financial statements since July 1, 2003 or their respective date of establishment/acquisition, whichever is later:

The following is a summary of the Company's major VIEs and VIEs' subsidiaries:

Name of VIE and VIEs' subsidiaries		Date of establishment/acquisition

For the six-month periods ended June 30, 2015 and 2016, the Company is considered the primary beneficiary of a VIE or VIEs' subsidiary and consolidated the VIE or VIEs' subsidiary if the Company had variable interests, that will absorb the entity's expected losses, receive the entity's expected residual returns, or both.

Details of certain key agreements with the VIEs are as follows:

Powers of Attorney: Each of the shareholders of our consolidated affiliated Chinese entities, except for Hui Cao and Hui Wang, signed an irrevocable power of attorney to appoint Ctrip Travel Network, Ctrip Travel Information or Wancheng, as attorney-in-fact to vote, by itself or any other person to be designated at its discretion, on all matters of the applicable consolidated affiliated Chinese entities. Each such power of attorney will remain effective as long as the applicable consolidated affiliated Chinese entity exists, and such shareholders of the applicable consolidated affiliated Chinese entities are not entitled to terminate or amend the terms of the power of attorneys without prior written consent from us.

As of the date of these interim condensed consolidated financial statements, each of the shareholders of Qunar Beijing, Hui Cao and Hui Wang, also signed an irrevocable power of attorney authorizing an appointee of Beijing Qunar Software Technology Company Limited, or Qunar Software, to exercise, in a manner approved by Qunar, on such shareholder's behalf the full shareholder rights pursuant to applicable laws and Qunar Beijing's articles of association, including without limitation full voting rights and the right to sell or transfer any or all of such shareholder's equity interest in Qunar Beijing. Each such power of attorney is effective until such time as such relevant shareholder ceases to hold any equity interest in Qunar Beijing. The terms of the power of attorney with respect to Qunar Beijing are otherwise substantially similar to the terms described in the foregoing paragraph.

Technical Consulting and Services Agreements: Ctrip Travel Information, Ctrip Travel Network and Wancheng, each a wholly owned PRC subsidiary of ours, provide our consolidated affiliated Chinese entities, except for Qunar Beijing, with technical consulting and related services and staff training and information services on an exclusive basis. We also maintain their network platforms. In consideration for our services, our consolidated affiliated Chinese entities agree to pay us service fees as calculated in such manner as determined by us from time to time based on the nature of service, which may be adjusted periodically. For the six month period ended June 30, 2016, our consolidated affiliated Chinese entities paid Ctrip Computer Technology (before our restructuring of business lines and restatement of contractual arrangements in 2015) or Ctrip Travel Information (after our restructuring of business lines and restatement of contractual arrangements in 2015) and Ctrip Travel Network a quarterly fee based on the number of transportation tickets sold and the number of packaged-tour products sold in the quarter, at an average rate from RMB3 (US$0.5) to RMB205 (US$30.9) per ticket and from RMB22 (US$3.3) to RMB186 (US$28) per person per tour. Although the service fees are typically determined based on the number of transportation tickets sold and packaged tour products sold, given the fact that the nominee shareholders of such consolidated affiliated Chinese entities have irrevocably appointed the employees of our subsidiaries to vote on their behalf on all matters they are entitled to vote on, we have the right to determine the level of service fees paid and therefore receive substantially all of the economic benefits of our consolidated affiliated Chinese entities in the form of service fees. The services fees paid by all of such consolidated affiliated Chinese entities as a percentage of their total net income were 138.3% and 100.6% for the six month period ended June 30, 2015 and 2016. Ctrip Travel Information, Ctrip Travel Network or Wancheng, as appropriate, will exclusively own any intellectual property rights arising from the performance of this agreement. The initial term of these agreements is 10 years and may be renewed automatically in 10-year terms unless we disapprove the extension. We retain the exclusive right to terminate the agreements at any time by delivering a 30-day advance written notice to the applicable consolidated affiliate Chinese entity.

As of the date of these interim condensed consolidated financial statements, pursuant to the restated exclusive technical consulting and services agreement between Qunar Beijing and Qunar Software, Qunar Software provides Qunar Beijing with technical, marketing and management consulting services on an exclusive basis in exchange for service fee paid by Qunar Beijing based on a set formula defined in the agreement subject to adjustment by Qunar Software at its sole discretion. This agreement will remain in effect until terminated unilaterally by Qunar Software or mutually. The terms of this agreement are otherwise substantially similar to the terms described in the foregoing paragraph.

Share Pledge Agreements: The shareholders of our consolidated affiliated Chinese entities, except for Hui Cao and Hui Wang, have pledged their respective equity interests in the applicable consolidated affiliated Chinese entities as a guarantee for the performance of all the obligations under the other contractual arrangements, including payment by such consolidated affiliated Chinese entities of the technical and consulting services fees to us under the technical consulting and services agreements, repayment of the business loan under the loan agreements and performance of obligations under the exclusive option agreements, each agreement as described herein. In the event any of such consolidated affiliated Chinese entity breaches any of its obligations or any shareholder of such consolidated affiliated Chinese entities breaches his or her obligations, as the case may be, under these agreements, we are entitled to enforce the equity pledge right and sell or otherwise dispose of the pledged equity interests after the pledge is registered with the relevant local branch of SAIC, and retain the proceeds from such sale or require any of them to transfer his or her equity interest without consideration to the PRC citizen(s) designated by us. These share pledge agreements are effective until two years after the pledgor and the applicable consolidated affiliated Chinese entities no longer undertake any obligations under the above-referenced agreements.

As of the date of these interim condensed consolidated financial statements, pursuant to the equity interest pledge agreement among Qunar Software, Hui Cao and Hui Wang, Hui Cao and Hui Wang have pledged their equity interests in Qunar Beijing along with all rights, titles and interests to Qunar Software as guarantee for the performance of all obligations under the relevant contractual arrangements mentioned herein. After the pledge is registered with the relevant local branch of SAIC, Qunar Software may enforce this pledge upon the occurrence of a settlement event or as required by the PRC law. The pledge, along with this agreement, will be effective upon registration with the local branch of the SAIC, and will expire when all obligations under the relevant contractual arrangements have been satisfied or when each of Hui Cao and Hui Wang completes a transfer of equity interest and ceases to hold any equity interest in Qunar Beijing. In enforcing the pledge, Qunar Software is entitled to dispose of the pledge and have priority in receiving payment from proceeds from the auction or sale of all or part of the pledge until the obligations are settled. The terms of this agreement are otherwise substantially similar to the terms described in the foregoing paragraph.

Loan Arrangements: Under the loan agreements we entered into with the shareholders of our consolidated affiliated Chinese entities, except for Hui Cao and Hui Wang, we extended long-term business loans to these shareholders of our consolidated affiliated Chinese entities with the sole purpose of providing funds necessary for the capitalization or acquisition of such consolidated affiliated Chinese entities. These business loan amounts were injected into the applicable consolidated affiliated Chinese entities as capital and cannot be accessed for any personal uses. The loan agreements shall remain effective until the parties have fully performed their respective obligations under the agreement, and the shareholders of such consolidated affiliated Chinese entities have no right to unilaterally terminate these agreements. In the event that the PRC government lifts its substantial restrictions on foreign ownership of the air-ticketing, travel agency, or value-added telecommunications business in China, as applicable, we will exercise our exclusive option to purchase all of the outstanding equity interests of our consolidated affiliated Chinese entities, as described in the following paragraph, and the loan agreements will be cancelled in connection with such purchase. However, it is uncertain when, if at all, the PRC government will lift any or all of these restrictions.

As of the date of this interim financial statements, pursuant to the loan agreement among Qunar Software, Hui Cao and Hui Wang, the loans extended by Qunar Software to each of Hui Cao and Hui Wang are only repayable by a transfer of such borrower's equity interest in Qunar Beijing to Qunar Software or its designated party, in proportion to the amount of the loan to be repaid. This loan agreement will continue in effect indefinitely until such time when (i) the borrowers receive a repayment notice from Qunar Software and fully repay the loans, or (ii) an event of default (as defined therein) occurs unless Qunar Software sends a notice indicating otherwise within 15 calendar days after it is aware of such event. The terms of this loan agreement is otherwise substantially similar to the terms described in the foregoing paragraphs.

Exclusive Option Agreements: As consideration for our entering into the loan agreements described above, each of the shareholders of our consolidated affiliated Chinese entities, except for Hui Cao and Hui Wang, has granted us an exclusive, irrevocable option to purchase, or designate one or more person(s) at our discretion to purchase, all of their equity interests in the applicable consolidated affiliated Chinese entities at any time we desire, subject to compliance with the applicable PRC laws and regulations. We may exercise the option by issuing a written notice to the relevant consolidated affiliated Chinese entity. The purchase price shall be equal to the contribution actually made by the shareholder for the relevant equity interest. Therefore, if we exercise these options, we may choose to cancel the outstanding loans we extended to the shareholders of such consolidated affiliated Chinese entities pursuant to the loan agreements as the loans were used solely for equity contribution purposes. The initial term of these agreements is 10 years and may be renewed automatically in 10-year terms unless we disapprove the extension. We retain the exclusive right to terminate the agreements at any time by delivering a written notice to the applicable consolidated affiliate Chinese entity.

Each of Hui Cao and Hui Wang also entered into equity option agreements with Qunar, Qunar Software and Qunar Beijing. These equity option agreements contain arrangements that are similar to that as described in the foregoing paragraph. This agreement will remain effective with respect to each of Qunar Beijing's shareholders until all of the equity interest has been transferred or Qunar terminates the agreement unilaterally with 30 days' prior written notice.

Our consolidated affiliated Chinese entities and their shareholders agree not to enter into any transaction that would affect the assets, obligations, rights or operations of our consolidated affiliated Chinese entities without our prior written consent. They also agree to accept our guidance with respect to day-to-day operations, financial management systems and the appointment and dismissal of key employees.

In addition, we also enter into technical consulting and services agreements with our majority or wholly owned subsidiaries of some of the consolidated affiliated Chinese entities, such as Chengdu Ctrip International, and these subsidiaries pay us service fees based on the level of services provided. The existence of such technical consulting and services agreements provides us with the enhanced ability to transfer economic benefits of these majority or wholly owned subsidiaries of the consolidated affiliated Chinese entities to us in exchange for the services provided, and this is in addition to our existing ability to consolidate and extract the economic benefits of these majority or wholly owned subsidiaries of the consolidated affiliated Chinese entities. For instance, the consolidated affiliated Chinese entities may cause the economic benefits to be channeled to them in the form of dividends, which then may be further consolidated and absorbed by us through the contractual arrangements described above.

Risks in relation to contractual arrangements between the Company's PRC subsidiaries and its affiliated Chinese entities:

The Company has been advised by Commerce & Finance Law Offices, its PRC legal counsel, that its contractual arrangements with its consolidated VIEs as described in the Company's annual report are valid, binding and enforceable under the current laws and regulations of China. Based on such legal opinion and the management's knowledge and experience, the Company believes that its contractual arrangements with its consolidated VIEs are in compliance with current PRC laws and legally enforceable. However, there may be in the event that the affiliated Chinese entities and their respective shareholders fail to perform their contractual obligations, the Company may have to rely on the PRC legal system to enforce its rights. The PRC legal system is based on written statutes. Prior court decisions may be cited for reference but have limited precedential value. Since 1979, PRC legislation and regulations have significantly enhanced the protections afforded to various forms of foreign investments in China. However, since the PRC legal system is still evolving, the interpretations of many laws, regulations and rules are not always uniform and enforcement of these laws, regulations and rules involve uncertainties, which may limit remedies available to us. In addition, any litigation in China may be protracted and result in substantial costs and diversion of resources and management attention. Due to the uncertainties with respect to the PRC legal system, the PRC government authorities may ultimately take a view contrary to the opinion of its PRC legal counsel with respect to the enforceability of the contractual arrangements.

There are, however, substantial uncertainties regarding the interpretation and application of current or future PRC laws and regulations. Accordingly, the Company cannot be assured that the PRC government authorities will not ultimately take a view that is contrary to the Company's belief and the opinion of its PRC legal counsel. On January 19, 2015, the Ministry of Commerce of the PRC, or (the "MOFCOM") released for public comments a proposed PRC law (the "Draft FIE Law") which includes VIEs within the scope of entities that could be considered to be foreign invested enterprises (or "FIEs") and may be subject to restrictions under existing PRC law on foreign investment in certain categories of industries. Specifically, the Draft FIE Law introduces the concept of "actual control" for determining whether an entity is considered to be an FIE. In addition to control through direct or indirect ownership on equity, the Draft FIE Law includes control through contractual arrangements within the definition of "actual control." If the Draft FIE Law is passed by the People's Congress of the PRC and goes into effect in its current form, these provisions regarding control through contractual arrangements could be construed to reach the Company's VIE arrangements, and as a result the Company's VIEs could become explicitly subject to the current restrictions on foreign investment in certain categories of industry. The Draft FIE Law includes provisions that would exempt from the definition of FIEs where the ultimate controlling shareholders are either entities organized under PRC law or individuals who are PRC citizens. The Draft FIE Law is silent as to what type of enforcement action might be taken against existing VIEs that operate in restricted or prohibited industries and are not controlled by entities organized under PRC law or individuals who are PRC citizens. If the contractual arrangements establishing the Company's VIE structure are found to be in violation of any existing law and regulations or future PRC laws and regulations or under the Draft FIE Law if it becomes effective, the relevant PRC government authorities will have broad discretion in dealing with such violation, including, without limitation, levying fines, confiscating our income or the income of our affiliated Chinese entities, revoking our business licenses or the business licenses of our affiliated Chinese entities, requiring us and our affiliated Chinese entities to restructure our ownership structure or operations and requiring us or our affiliated Chinese entities to discontinue any portion or all of our value-added telecommunications, air-ticketing, travel agency or advertising businesses. Any of these actions could cause significant disruption to the Company's business operations, and have a severe adverse impact on the Company's cash flows, financial position and operating performance. If the imposing of these penalties cause the Company to lose its rights to direct the activities of and receive economic benefits from its VIEs, which in turn may restrict the Company's ability to consolidate and reflect in its financial statements the financial position and results of operations of its VIEs.

Summary financial information of the Group's VIEs in the consolidated financial statements

Pursuant to the contractual arrangements with the VIEs, the Company has the power to direct activities of the VIEs, and can have assets transferred freely out of the VIEs without any restrictions. Therefore the Company considers that there is no asset of a consolidated VIE that can be used only to settle obligations of the VIE, except for registered capital and PRC statutory reserves of the VIEs amounting to a total of RMB549 million as of June 30, 2016. As all the consolidated VIEs are incorporated as limited liability companies under the PRC Company Law, creditors of the VIEs do not have recourse to the general credit of the Company for any of the liabilities of the consolidated VIEs.

Summary financial information of the VIEs, which represents aggregated financial information of the VIEs and their respective subsidiaries included in the accompanying consolidated financial statements, is as follows:

As of December 31, 2015 and June 30, 2016, the VIEs' assets mainly consisted of cash and cash equivalent (December 31, 2015: RMB2.8 billion, June 30, 2016: RMB4.1 billion), prepayments and other current assets (December 31, 2015: RMB4.1 billion, June 30, 2016: RMB4.0 billion), accounts receivables (December 31, 2015: RMB2.7 billion, June 30, 2016: RMB3.8 billion), investments (non-current) (December 31, 2015: RMB2.4 billion, June 30, 2016: RMB2.5 billion) and short-term investment (December 31, 2015: RMB3.1 billion, June 30, 2016: RMB2.4 billion). The inter-company receivables of RMB3.8 billion and RM6.4 billion as of December 31, 2015 and June 30, 2016 mainly represented the cash paid by a VIE to one of the Company's WFOEs for treasury cash management purpose.

As of December 31, 2015 and June 30, 2016, the VIEs' liabilities mainly consisted of accounts payable (December 31, 2015: RMB4.0 billion, June 30, 2016: RMB4.9 billion), advance from end users (December 31, 2015: RMB5.1 billion, June 30, 2016: RMB4.8 billion), other payables and accruals (December 31, 2015: RMB2.1 billion, June 30, 2016: RMB1.0 billion), salary and welfare payable (December 31, 2015: RMB217 million, June 30, 2016: RMB121million) and taxes payable (December 31, 2015: RMB689 million, June 30, 2016: RMB106 million). The inter-company payables as of December 31, 2015 and June 30, 2016 were RMB8.6 billion and RMB11.8 billion, respectively, which primarily consisted of the payables due to Ctrip.com (Hong Kong) Limited ("Ctrip HK"), one of the Company's wholly-owned subsidiaries, for its payment of overseas air tickets and tour packages on behalf of a VIE and another VIEs' subsidiary and the service fees payable to the WFOEs under the technical consulting and services agreements, which are operational in nature from the VIEs and their subsidiaries' perspectives.

	Six-month period ended June 30, 2015			Six-month period ended June 30, 2016
	RMB			RMB
Net revenues		2,996,244,090			3,801,338,504

Net loss		(152,633,420	)		(53,675,461	)

As aforementioned, the VIEs mainly conduct air-ticketing, travel agency, advertising and value-added telecommunication businesses. Revenues from VIEs accounted for around 62% and 44% of the Company's total revenues in six-month period ended June 30, 2015 and 2016. The air-ticketing and packaged-tour revenues continued to increase, primarily driven by the increase in the air-ticketing volume and leisure travel volume.

The VIEs' net loss before the deduction of the inter-company consulting fee charges were RMB153 million and RMB54 million for the six-month period ended June 30, 2015 and 2016, respectively.

The amount of service fees paid by all the VIEs as a percentage of the VIEs' total net income were 138.3% and 100.6% for the six-month period ended June 30, 2015 and 2016, respectively.

The WFOEs are the sole and exclusive provider of technical consulting and related services and information services for the VIEs. Pursuant to the Exclusive Technical Consulting and Service Agreements, the VIEs pay service fees to the WFOEs based on the VIEs' actual operating results. The WFOEs are entitled to receive substantially all of the net income and transfer a majority of the economic benefits in the form of service fees from the VIEs and VIEs' subsidiaries to the WFOEs.

Currently there is no contractual arrangement that could require the Company to provide additional financial support to the consolidated VIEs. As the Company is conducting certain business in the PRC mainly through the VIEs, the Company may provide such support on a discretionary basis in the future, which could expose the Company to a loss.

Foreign currencies

The Group's reporting currency is RMB. The Company's functional currency is US$. The Company's operations are conducted through the subsidiaries and VIEs where the local currency is the functional currency and the financial statements of those subsidiaries are translated from their respective functional currencies into RMB.

Transactions denominated in currencies other than functional currencies are translated at the exchange rates quoted by the People's Bank of China (the "PBOC"), the Hong Kong Association of Banks (the "HKAB") or major Taiwan banks, prevailing or averaged at the dates of the transaction for PRC and Hong Kong subsidiaries and ezTravel, a Taiwan subsidiary respectively. Gains and losses resulting from foreign currency transactions are included in the consolidated statements of income and comprehensive income. Monetary assets and liabilities denominated in foreign currencies are translated using the applicable exchange rates quoted by the PBOC, HKAB or banks located in Taiwan at the balance sheet dates. All such exchange gains and losses are included in the statements of income.

Assets and liabilities of the group companies are translated from their respective functional currencies to the reporting currency at the exchange rates at the balance sheet dates, equity accounts are translated at historical exchange rates and revenues and expenses are translated at the average exchange rates in effect during the reporting period. The exchange differences for the translation of group companies with non-RMB functional currency into the RMB functional currency are included in foreign currency translation adjustments, which is a separate component of shareholders' equity on the consolidated financial statements.

Translations of amounts from RMB into US$ are solely for the convenience of the reader and were calculated at the rate of US$1.00 = RMB6.6459 on June 30, 2016, representing the certificated exchange rate published by the Federal Reserve Board. No representation is intended to imply that the RMB amounts could have been, or could be, converted, realized or settled into US$ at that rate on June 30, 2016, or at any other rate.

Cash and cash equivalents

Cash includes currency on hand and deposits held by financial institutions that can be added to or withdrawn without limitation. Cash equivalents represent short-term, highly liquid investments that are readily convertible to known amounts of cash and with original maturities from the date of purchase of generally three months or less.

Restricted cash

Restricted cash represents cash that cannot be withdrawn without the permission of third parties. The Group's restricted cash is substantially cash balance on deposit required by its business partners and commercial banks.

Short-term investment

Short-term investments represent the investments issued by commercial banks or other financial institutions with a variable interest rate indexed to the performance of underlying assets within one year. The Company elected the fair value method at the date of initial recognition and carried these investments subsequently at fair value. Changes in the fair value are reflected in the consolidated statements of income and comprehensive income.

Long term loan receivable

Long-term loan receivables are recorded at cost and compounded accrued interests as we do not intend to sell the security, or it is more likely than not that the Company will not be required to sell the security before full recovery of our cost. The Company evaluates the qualitative criteria to determine whether we expect to recover our cost.

Land use rights

Land use rights represent the prepayments for usage of the parcels of land where the office buildings are located, are recorded at cost, and are amortized over their respective lease periods (usually over 40 to 50 years).

Property, equipment and software

Property, equipment and software are stated at cost less accumulated depreciation and amortization. Depreciation and amortization are computed using the straight-line method over the following estimated useful lives, taking into account any estimated residual value:

Building		20 - 40 years
Leasehold improvements		Lesser of the term of the lease or the estimated useful lives of the assets
Website-related equipment		5 years
Computer equipment		3 - 5 years
Furniture and fixtures		3 - 5 years
Software		3 - 5 years

Construction in progress is stated at cost. Construction in progress as of December 31, 2015 mainly refers to costs associated with the purchase of building in Shanghai Sky SOHO and construction of information and technology center in Chengdu before the buildings are put into service. All direct costs related to the new buildings are capitalized as construction in progress until it is substantially completed and available for use.

The Company recognized the disposal of Property, equipment and software in general and administrative expenses.

Investments

The Company investments include held to maturity investments, available-for-sale investments, equity method investments and cost method investments in certain publicly traded companies and privately-held companies.

The securities that the Company has positive intent and ability to hold to maturity are classified as held to maturity investments and stated at amortized cost. Cost method is used for investments over which the Company does not have the ability to exercise significant influence. Gain or losses are realized when such investments are sold or when dividends are declared or payments are received or when impaired. The Company applies equity method in accounting for its investments in entities in which the Company has the ability to exercise significant influence but does not own a majority equity interest or otherwise controls and the investments are either common stock or in-substance common stocks. Unrealized gains on transactions between the Company and the affiliated entity are eliminated to the extent of the Company's interest in the affiliated entity; unrealized losses are also eliminated unless the transaction provides evidence of an impairment of the asset transferred. The Company classifies its investments in debt and equity securities, that are not accounted for as cost or equity method investments, into one of three categories and accounts for these as follows: (i) debt securities that the Company has the positive intent and the ability to hold to maturity are classified as "held to maturity" and reported at amortized cost; (ii) debt and equity securities that are bought and held principally for the purpose of selling them in the near term are classified as "trading securities" with unrealized holding gains and losses included in earnings; (iii) debt and equity securities not classified as held to maturity or as trading securities are classified as "available-for-sale" and reported at fair value through other comprehensive income. Realized gains or losses are charged to earnings during the period in which the gains or losses are realized.

The Company monitors its investments for other-than-temporary impairment by considering factors including, but not limited to, current economic and market conditions, the operating performance of the companies including current earnings trends and other company-specific information.

Fair value measurement of financial instruments

Financial assets and liabilities of the Group primarily comprise of cash and cash equivalents, restricted cash, time deposits, financial products, accounts receivable, due from related parties, available-for-sale investments, accounts payable, due to related parties, advances from end users, short-term bank borrowings, other short-term liabilities and long-term debts. As of December 31, 2015 and June 30, 2016, the Company does not hold any derivative instruments, and except for long-term debts and available-for-sale investments, carrying values of these financial instruments approximated their fair values because of their generally short maturities. The Company reports available-for-sale investments at fair value at each balance sheet date and changes in fair value are reflected in the statements of income and comprehensive income. The Company disclosed the fair value of its long-term debts based on Level 2 inputs in Note 8.

We measure our financial assets and liabilities using inputs from the following three levels of the fair value hierarchy. The three levels are as follows:

Level 1 inputs are unadjusted quoted prices in active markets for identical assets that the management has the ability to access at the measurement date.

Level 2 inputs include quoted prices for similar assets in active markets, quoted prices for identical or similar assets in markets that are not active, inputs other than quoted prices that are observable for the asset (i.e., interest rates, yield curves, etc.), and inputs that are derived principally from or corroborated by observable market data by correlation or other means (market corroborated inputs).

Level 3 includes unobservable inputs that reflect the management's assumptions about the assumptions that market participants would use in pricing the asset. The management develops these inputs based on the best information available, including the own data.

Business combination

U.S. GAAP requires that all business combinations not involving entities or businesses under common control be accounted for under the purchase method. The Group applies ASC 805, "Business combinations", the cost of 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. 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 non-controlling interests. The excess of the (i) the total of cost of acquisition, fair value of the non-controlling 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 the consolidated statements of income and comprehensive income.

The determination and allocation of fair values to the identifiable assets acquired and liabilities assumed is based on various assumptions and valuation methodologies requiring considerable management judgment. 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. Management 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 products and forecasted life cycle and forecasted cash flows over that period. Although we believe that the assumptions applied in the determination are reasonable based on information available at the date of acquisition, actual results may differ from the forecasted amounts and the difference could be material.

Acquisitions

The Company completed several transactions to acquire controlling shares to enrich its products and to expand business. The Company makes estimates and judgments in determining the fair value of the acquired assets and liabilities, based in part on independent appraisal reports as well as its experience with purchasing similar assets and liabilities in similar industries. The amount excess of the purchase price over the fair value of the identifiable assets and liabilities acquired is recorded as goodwill. The major acquisitions during the periods presented are as follows:

Qunar Cayman Islands Limited ("Qunar")

In October 2015, the Company completed a share exchange transaction with Baidu, Inc. ("Baidu"), which was the principal shareholder of Qunar, upon completion of the exchange, the Company issued approximately 11.5 million ordinary shares, with the fair value of US$ 3.4 billion (RMB 21.7 billion) to Baidu in exchange for approximately 179 million Class A (There were 193 million outstanding Class A shares in Qunar) and 11 million Class B ordinary shares of Qunar. The Class A and Class B represents 3 votes and 1 vote per share respectively, and Class A ordinary shares were converted into Class B ordinary shares upon transfer. After the transaction, Ctrip owned ordinary share of Qunar representing approximately 45% of Qunar's aggregate voting interest and 48% economic interest.

In connection with the transaction with Baidu, on December 10, 2015, the Company issued approximately 4 million ordinary shares to certain special purpose vehicles in exchange for approximately 66 million Class B ordinary shares of Qunar issued as equity incentives to Qunar's employees.

Below is the summary of the fair value of acquisition cost for these acquisition:

	RMB		US$
Fair value of previously held equity interest(1)		21,698,582,100		3,416,184,974
Consideration paid in December 2015		10,842,783,275		1,687,067,570

Total purchase cost		32,541,365,375		5,103,252,544


(1)	Which represents fair value of purchase consideration for the initial 45% equity method investment in October 2015

Under US GAAP, as a result of the above transactions, the Company is deemed to be the beneficial owner of 256 million Class B ordinary shares of Qunar representing majority voting interest and therefore accounts for these transactions as step acquisitions of business combination. The previously held equity interest of Qunar from the exchange transaction with Baidu was accounted for using equity method until the Company's consolidation of Qunar upon completion of the transaction with the Qunar shareholders in December 2015. The financial statements of Qunar are consolidated by the Company from December 31, 2015 on since the financial results of Qunar during the period from December 10 through December 31, 2015 were not material.

The preliminary allocation of the purchase price of the assets acquired and liabilities assumed based on their fair values was as follows. The fair value of non-controlling interest was measured based on the purchase price, taking into account a discount reflective of the non-controlling nature of the interest based on the market price of Qunar's publically traded shares.

Total purchase consideration		32,541,365,375

The newly identifiable intangible assets of Qunar primarily consist of trademark and domain, technology and supplier network for new products. The trademark and domain are indefinite-lived intangible assets. The estimated fair value of the amortizable intangible assets (technology and supplier network for new products) is expected to amortised on a straight-line basis over a weighted average period of 5.2 years.

In the first half year of 2016, the Company made certain investments, in the form of limited partnership capital contribution or other financing arrangements respectively, in several non-U.S. investment entities, with an aggregate fair value of approximately US$2.9 billion (RMB 19 billion), including US$1 billion (RMB 6.5 billion) cash and newly issued ordinary shares (the "Investment"). These investment entities have spent the Investment to acquire the majority of minority stake of Qunar through privately negotiated transactions. In accordance with ASC 810, the Company consolidates the financial statements of these investment entities and as such the investments are eliminated in consolidation. The Company accounts for the subsequent purchases of the Qunar non-controlling shares as equity transactions by adjusting the carrying amount of non-controlling interest of Qunar to reflect the decrease in the non-controlling interest's ownership in Qunar by RMB15.5 billion. The difference between the amount of the change in non-controlling interest and the consideration paid was recognized in additional paid-in capital of the Company with amount of RMB3.7 billion against the US$ 1.9 billion (RMB 12.6 billion) of additional paid-in capital from the newly issued ordinary shares.

The following unaudited pro forma consolidated financial information reflects the results of operations for the period ended June 30, 2015, as if the Qunar business combination had occurred on January 1, 2015, and after giving effect to purchase accounting adjustments. These pro forma results have been prepared for comparative purposes only and do not purport to be indicative of what operating results would have been had the acquisition actually took place on the beginning of the period presented, and may not be indicative of future operating results.

Travelfusion Limited ("Travelfusion")

In January, 2015, the Company acquired 70% equity interest of Travelfusion. Travelfusion is a UK-based leading online Low Cost Carrier (LCC) travel content aggregator and innovator of Direct Connect global distribution solutions.

The purchase consideration is RMB721 million (GBP75.6 million). The results of Travelfusion have been included in the consolidated financial statements of the Company since the acquisition date. As of December 31, 2015, the total unpaid cash consideration was RMB 41 million and will be paid in 2016. On the acquisition date, the preliminary allocation of the purchase price of the assets acquired and liabilities assumed based on their fair values was as follows. The non-controlling interest represents the fair value of the 30% equity interest not held by the Company:

	RMB
Net assets		36,936,493
Identifiable intangible assets—trademark and domain		78,058,071

Total purchase consideration		720,536,040

The identifiable intangible assets primarily consist of trademark and domain, business relationship and IT Platform. The trademark and domain are indefinite-lived intangible assets. The fair values of the business relationship and IT Platform are amortized on a straight-line basis over 10 years and 5 years, respectively.

Other than the acquisitions disclosed above, none of other acquisition incurred during the periods presented is material to our businesses or financial results.

Goodwill and other intangible assets

Goodwill represents the excess of the purchase price over the fair value of the identifiable assets and liabilities acquired as a result of the Company's acquisitions of interests in its subsidiaries and consolidated VIEs.

Goodwill is not amortized but is reviewed at least annually for impairment or earlier, if an indication of impairment exists. Recoverability of goodwill is evaluated using a two-step process. In the first step, the fair value of a reporting unit is compared to its carrying value. If the fair value of a reporting unit exceeds the carrying value of the net assets assigned to a reporting unit, goodwill is considered not impaired and no further testing is required. If the carrying value of the net assets assigned to a reporting unit exceeds the fair value of a reporting unit, the second step of the impairment test is performed in order to determine the implied fair value of a reporting unit's goodwill. Determining the implied fair value of goodwill requires valuation of a reporting unit's tangible and intangible assets and liabilities in a manner similar to the allocation of purchase price in a business combination. If the carrying value of a reporting unit's goodwill exceeds its implied fair value, goodwill is deemed impaired and is written down to the extent of the difference. The Company estimates total fair value of the reporting unit using discounted cash flow analysis, and makes assumptions regarding future revenue, gross margins, working capital levels, investments in new products, capital spending, tax, cash flows, and the terminal value of the reporting unit.

For the six-month period ended June 30, 2016, the increase of goodwill mainly includes one business acquisition in 2016, and measurement period adjustments as well as foreign currency differences. The Company paid RMB 54.6 million for the acquisition in 2016, and none of the acquisitions occurred during the periods presented was material. There was no impairment of goodwill during the periods ended June 30, 2015 and 2016. Each quarter the Company reviews the events and circumstances to determine if goodwill impairment may be indicated.

Separately identifiable intangible assets that have determinable lives continue to be amortized and consist primarily of non-compete agreements, customer list, supplier relationship, technology and business relationship as of December 31, 2015 and June 30, 2016. The Company amortizes intangible assets on a straight-line basis over their estimated useful lives, which is three to ten years. The estimated life of amortized intangibles is reassessed if circumstances occur that indicate the life has changed. Other intangible assets that have indefinite useful life primarily include trademark and domain names as of December 31, 2015 and June 30, 2016. The Company evaluates indefinite-lived intangible assets each reporting period to determine whether events and circumstances continue to support an indefinite useful life. If an intangible asset that is not being amortized is subsequently determined to have a finite useful life, the asset is tested for impairment. The Company estimates total fair value of the reporting unit using discounted cash flow analysis, and makes assumptions regarding future revenue, gross margins, working capital levels, investments in new products, capital spending, tax, cash flows, and the terminal value of the reporting unit.

The Company reviews intangible assets with indefinite lives annually for impairment.

No impairment on other intangible assets was recognized for the six-month periods ended June 30, 2015 and 2016.

Impairment of long-lived assets

Long-lived assets (including intangible with definite lives) are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Reviews are performed to determine whether the carrying value of asset group is impaired, based on comparison to undiscounted expected future cash flows. If this comparison indicates that there is impairment, the Group recognizes impairment of long-lived assets to the extent the carrying amount of such assets exceeds the fair value.

Accrued liability for customer reward program

The Group's end users participate in a reward program, which provides travel awards and other gifts to members based on accumulated membership points that vary depending on the services rendered and fees paid. The estimated incremental costs to provide free travel and other gifts are recognized as sales and marketing expense in the statements of income and comprehensive income and accrued for as a current liability as members accumulate points. As members redeem awards or their entitlements expire, the accrued liability is reduced correspondingly. As of December 31, 2015, and June 30, 2016, the Group's accrued liability for its customer reward program amounted to RMB593 million and RMB633 million, respectively, based on the estimated liabilities under the customer reward program. Our expenses for the customer rewards program were approximately RMB225 million and RMB116 million for the six-month periods ended June 30, 2015 and 2016.

Deferred revenue

The Group has the coupon program, through which the Group provides coupons for end users who book selected hotels online through website. The end users who use the coupons receive credits in their virtual cash accounts upon check-out from the hotels and reviews for hotels submitted. The end users may redeem the amount of credits in their virtual cash account in cash, voucher, or mobile phone credit. The Group accounts for the estimated cost of future usage of coupons as contra-revenue or sales and marketing expenses in the consolidated statements.

Revenue recognition

The Group presents majority of its revenues on a net basis. Revenues are recognized at gross amounts where the Group undertakes the majority of the business risks by pre-purchasing inventories and acts as principal related to the services provided. The amount of revenues recognized at gross basis was immaterial during the six-month periods ended June 30, 2015 and 2016, respectively.

Effective August 1, 2013, pursuant to Circular Caishui [2013] No. 37 released by the Ministry of Finance of China, entities within transportation service and selected modern service industries will switch from a business tax payer to a VAT payer.

Accommodation reservation services

The Group receives commissions from travel suppliers for hotel room reservations through the Group's transaction and service platform. Commissions from hotel reservation services rendered are recognized after end users have completed their stay at the applicable hotel and upon confirmation of pending payment of the commissions by the hotel. Contracts with certain travel suppliers contain incentive commissions typically subject to achieving specific performance targets and such incentive commissions are recognized when it is reasonably assured that the Group is entitled to such incentive commissions. The Group generally receives incentive commissions from monthly arrangements with hotels based on the number of hotel room reservations where end users have completed their stay. The Group presents revenues from such transactions on a net basis in the statements of income and comprehensive income as the Group, generally, does not assume inventory risks and has no obligations for cancelled hotel reservations.

Transportation ticketing services

Transportation ticketing services revenues mainly represent revenues from tickets reservations and other related services. The Group receives commissions from travel suppliers for ticketing services through the Group's transaction and service platform under various services agreements. Commissions from ticketing services rendered are recognized after tickets are issued. The Group presents revenues from such transactions on a net basis in the statements of income as the Group, generally, does not assume inventory risks and has no obligations for cancelled airline ticket reservations. Loss due to obligations for cancelled ticket reservations is minimal in the past.

Packaged-tour

The Group receives referral fees from travel product providers for packaged-tour products and services through the Group's transaction and service platform. Referral fees are recognized as commissions on a net basis after the packaged-tour service are rendered and collections are reasonably assured.

Corporate travel

Corporate travel management revenues primarily include commissions from air ticket booking, hotel reservation and packaged-tour services rendered to corporate clients. The Group contracts with corporate clients based on service fee model. Travel reservations are made via on-line and off-line services for air tickets, hotel and package-tour. Revenue is recognized on a net basis after the services are rendered, e.g. air tickets are issued, hotel stays or packaged-tour are completed, and collections are reasonably assured.

Other businesses

Other businesses comprise primarily of online advertising services, the sale of Property Management System ("PMS"), and related maintenance service.

Shanghai Ctrip Commerce and Qunar receive advertising revenues, which principally represent the sale of banners or sponsorship on the website and mobile from end users. Advertising revenues are recognized ratably over the fixed term of the agreement as services are provided.

Jointwisdom, a subsidiary of the Company, conducts sale of PMS and related maintenance service. The sale of PMS is recognized upon customer acceptance. Maintenance service is recognized ratably over the term of the maintenance contract on a straight-line basis.

Cost of revenues

Cost of revenues consists primarily of payroll compensation of customer service center personnel, payments to travel suppliers, credit card service fee, telecommunication expenses, direct cost of principal travel tour services, depreciation, rentals and related expenses incurred by the Group's transaction and service platform which are directly attributable to the rendering of the Group's travel related services and other businesses.

Product development

Product development expenses include expenses incurred by the Group to develop the Group's travel supplier networks as well as to maintain, monitor and manage the Group's transaction and service platform. The Group recognizes website, software and mobile applications development costs in accordance with ASC 350-50 "Website development costs" and ASC 350-40 "Software—internal use software" respectively. The Group expenses all costs that are incurred in connection with the planning and implementation phases of development and costs that are associated with repair or maintenance of the existing websites and mobile applications or the development of software or mobile applications for internal use and websites content.

Sales and marketing

Sales and marketing expenses consist primarily of costs of payroll and related compensation for the Company's sales and marketing personnel, advertising expenses, and other related marketing and promotion expenses. Advertising expenses, amounting to approximately RMB769 million and RMB1.3 billion for the six-month periods ended June 30, 2015 and 2016 respectively, are charged to the statements of income as incurred.

Share-based compensation

Under ASC 718, the Company applied the Black-Scholes valuation model in determining the fair value of options granted. Risk-free interest rates are based on US Treasury yield for the terms consistent with the expected life of award at the time of grant. Expected life is based on historical exercise patterns, for options granted before 2008 which the Company has historical data of and believes are representative of future behavior. For options granted since 2008, the Company used simplified method to estimate its expected life. Expected dividend yield is determined in view of the Company's historical dividend payout rate and future business plan. The Company estimates expected volatility at the date of grant based on historical volatilities. The Company recognizes compensation expense on all share-based awards on a straight-line basis over the requisite service period. Forfeiture rate is estimated based on historical forfeiture patterns and adjusted to reflect future change in circumstances and facts, if any. If actual forfeitures differ from those estimates, we may need to revise those estimates used in subsequent periods.

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. Share-based compensation expense was recorded net of estimated forfeitures such that expense was recorded only for those share-based awards that are expected to vest.

According to ASC 718, a change in any of the terms or conditions of stock options shall be accounted for as a modification of the plan. Therefore, the Company calculates incremental compensation cost of a modification as the excess of the fair value of the modified option over the fair value of the original option immediately before its terms are modified, measured based on the share price and other pertinent factors at the modification date. For vested options, the Company would recognize incremental compensation cost in the period the modification occurs and for unvested options, the Company would recognize, over the remaining requisite service period, the sum of the incremental compensation cost and the remaining unrecognized compensation cost for the original award on the modification date.

According to ASC 718, the Company classifies options or similar instruments as liabilities if the entity can be required under any circumstances to settle the option or similar instrument by transferring cash or other assets and such cash settlement is probable. The percentage of the fair value that is accrued as compensation cost at the end of each period shall equal the percentage of the requisite service that has been rendered at that date. Changes in fair value of the liability classified award that occur during the requisite service period shall be recognized as compensation cost over that period. Changes in fair value that occur after the end of the requisite service period are compensation cost of the period in which the changes occur. Any difference between the amount for which a liability award is settled and its fair value at the settlement date as estimated is an adjustment of compensation cost in the period of settlement.

Share incentive plans of Ctrip

On November 5, 2004, the Company's board of directors adopted a 2005 Employee's Stock Option Plan ("2005 Option Plan"). The 2005 Option Plan was approved by the shareholders of the Company in October 2005. The Company has reserved 3,000,000 ordinary shares for future issuances of options under the 2005 Option Plan. The terms of the 2005 Option Plan are substantially similar to the Company's 2003 Option Plan. As of December 31, 2015 and June 30, 2016, 179,453 and 165,347 options were outstanding under the 2005 Option Plan respectively.

On October 17, 2007, the Company adopted a 2007 Share Incentive Plan ("2007 Incentive Plan"), which was approved by the shareholders of the Company on June 15, 2007. Under the 2007 Incentive Plan, the maximum aggregate number of shares, which may be issued pursuant to all share-based awards (including Incentive Share Options and Restricted Share Units ("RSU")), is one million ordinary shares as of the first business day of 2007, plus an annual increase of one million shares to be added on the first business day of each calendar year beginning in 2008 to 2016. Under the 2007 Incentive Plan, the directors may, at their discretion, grant any employees, officers, directors and consultants of the Company and/or its subsidiaries such share-based awards. Shares options granted under 2007 Incentive Plan are vested over a period of 4 years. The Company granted 134,534 and 1,062,302 new shares options and RSUs to employees with 4 year requisite service period for the six-month period ended June 30, 2015 and 2016, respectively. As of December 31, 2015 and June 30, 2016, 4,826,009 and 4,759,890 options and 865,409 and 1,387,862 RSUs were outstanding under the 2007 Incentive Plan.

As of June 30, 2016, there was US$350 million of total unrecognized compensation cost, net of estimated forfeitures, related to unvested share options and RSUs which are expected to be recognized. Total unrecognized compensation cost may be adjusted for future changes in estimated forfeitures. Total cash received from the exercise of share options amounted to RMB52,028,317 and RMB119,454,908 for the six-month period ended June 30, 2015 and 2016, respectively.

Share incentive plans of Qunar

In November 2007, Qunar's shareholders approved the 2007 Share Incentive Plan (the "2007 Share Incentive Plan"), which is administered by Qunar's Board of Directors or any of its committees. Under the Plan, Qunar's Board of Directors may grant options to its employees, directors and consultants to purchase an aggregate of no more than 9,600,140 ordinary shares of the Company. On December 29, 2011, Qunar's Board of Directors approved the increase of the number of shares available for issuance under the 2007 Share Incentive Plan from 20,724,362 to 26,060,000 shares. On August 10, 2012, Qunar's Board of Directors approved that starting from January 1, 2013, the number of shares available for issuance under the 2007 Share Incentive Plan would increase annually by 1.5% of the total outstanding ordinary and redeemable ordinary shares as of January 1 of that respective calendar year. On September 22, 2013, the Board of Directors approved an increase in the number of shares available for issuance under the 2007 Share Incentive Plan by 6,066,896 shares. The options granted have a contractual term of ten years and generally vest over a four-year period, with 25% of the awards vesting one year after the date of grant and 1/16 of the remaining grants vesting on a quarterly basis thereafter. In December 2015, Qunar modified the awards under the 2007 Share Incentive Plan to be convertible to Ctrip American depositary shares ("ADSs") at a ratio of 1 Qunar ADS to 0.725 Ctrip ADS. Unvested awards under the 2007 Share Incentive Plan became fully vested for certain employees and all cliff vesting conditions and performance-based vesting conditions were removed from all outstanding awards under the 2007 Share Incentive Plan. As of December 31, 2015 and June 30, 2016, 8,596,548 and 7,660,524 options were outstanding under the 2007 Qunar Option Plan respectively.

On November 18, 2015, Board of Directors of Qunar approved another share incentive plan (the "2015 Qunar Share Incentive Plan"), under which share options granted, when vested and exercised, will be entitled to be convertible to Ctrip ADSs at a ratio of 1 Qunar ADS to 0.725 Ctrip ADS. Certain options granted under the 2015 Qunar Share Incentive Plan vest immediately upon grant, while others vest on a quarterly basis on the same vesting schedule as those outstanding awards under the 2007 Share Incentive Plan. Under the 2015 Qunar Share Incentive Plan, Qunar may grant options to its employees, directors and consultants to purchase an aggregate of no more than 28,476,795 ordinary shares of the Company. These options granted have a contractual term of ten years. As of December 31, 2015 and June 30, 2016, 10,162,890 and 7,789,191 options were outstanding under the 2015 Qunar Option Plan respectively.

Operating leases

Leases where substantially all the rewards and risks of ownership of assets remain with the leasing company are accounted for as operating leases. Payments made under operating leases net of any incentives received by the Group from the leasing company are charged to the statements of income on a straight-line basis over the lease periods.

Taxation

Deferred income taxes are provided using the balance sheet liability method. Under this method, deferred income taxes are recognized for the tax consequences of significant temporary differences by applying enacted statutory rates applicable to future years to differences between the financial statement carrying amounts and the tax bases of existing assets and liabilities. The tax base of an asset or liability is the amount attributed to that asset or liability for tax purposes. The effect on deferred taxes of a change in tax rates is recognized in income in the period enacted. A valuation allowance is provided to reduce the amount of deferred tax assets if it is considered unlikely that some portion of, or all of, the deferred tax assets will not be realized.

The Company applies ASC 740, "Income Taxes". It clarifies the accounting for uncertainty in income taxes recognized in the Company's consolidated financial statements and prescribes a more likely than not threshold for financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. It also provides guidance on derecognition of income tax assets and liabilities, classification of current and deferred income tax assets and liabilities, accounting for interest and penalties associated with tax positions, accounting for income taxes in interim periods, and income tax disclosures.

Other income (net)

Other income consists of gain on deconsolidation of subsidiaries, financial subsidies, investment income and foreign exchange gains/(losses). Financial subsidies from local PRC government authorities were recorded as other income in the consolidated statements of income. There are no defined rules and regulations to govern the criteria necessary for companies to enjoy such benefits and the amount of financial subsidy are determined at the discretion of the relevant government authorities. Financial subsidies are recognized as other income when received. Components of other income for the six-month period ended June 30, 2015 and 2016 were as follows:

	Six-month period ended June 30, 2015			Six-month period ended June 30, 2016
	RMB			RMB
Gain on disposal of cost method investment (Note 3)		—			141,094,189
Gain on disposal of available-for-sale investment (Note 3)		—			140,651,759
Subsidy income		17,803,446			66,136,662
Reimbursement from the depository		11,582,882			12,881,408
Gain on deconsolidation of subsidiaries		1,873,977			3,289,000

Bank charges		(37,907,809	)		(50,624,064	)
Others		13,130,209			34,919,435

Total		(3,571,631	)		287,772,833

Statutory reserves

The Company's PRC subsidiaries and the VIEs are required to allocate at least 10% of their after-tax profit to the general reserve in accordance with the PRC accounting standards and regulations. The allocation to the general reserve will cease if such reserve has reached to 50% of the registered capital of each company. Appropriations to the enterprise expansion fund, staff welfare and bonus fund are at the discretion of the board of directors of Ctrip Computer Technology, Ctrip Travel Information, Ctrip Travel Network, Ctrip Information Technology and Jointwisdom, the subsidiaries of the Company. Appropriations to discretionary surplus reserve are at the discretion of the board of directors of the VIEs. These reserves can only be used for specific purposes and are not transferable to the Company in form of loans, advances, or cash dividends. Additionally, ezTravel, the Company's subsidiary incorporated in Taiwan, is also required to allocate 10% of its after-tax profit to the statutory reserve in accordance with the Taiwan regulations. There is no such regulation of providing statutory reserve in Hong Kong. During the 6-month period ended June 30, 2015 and 2016, no appropriations to statutory reserves has been made.

Dividends

Dividends are recognized when declared.

PRC regulations currently permit payment of dividends only out of accumulated profits as determined in accordance with PRC accounting standards and regulations. The Company's PRC subsidiaries can only distribute dividends after they have met the PRC requirements for appropriation to statutory reserves. Additionally, as the Company does not have any direct ownership in the VIEs, the VIEs cannot directly distribute dividends to the Company. The PRC government imposes control over its foreign currency reserves in part through direct regulation of the conversion of RMB into foreign exchange and through restrictions on foreign trade. As substantially all of our revenues are in RMB, any restrictions on currency exchange may limit our ability to use revenue generated in RMB to fund our business activities outside China or to make dividend payments in U.S. dollars. Restricted net assets of the Company's PRC subsidiaries and VIEs not distributable in the form of dividends to the parent as a result of the aforesaid PRC regulations and other restrictions were RMB2.8 billion as of June 30, 2016.

As a result of the aforementioned PRC regulation and the Company's organizational structure, accumulated profits of the subsidiaries in PRC distributable in the form of dividends to the parent as of December 31, 2015 and June 30, 2016 were RMB7.2 billion and RMB7.1 billion, respectively. The Company's PRC subsidiaries and VIEs are able to enter into royalty and trademark license agreements or certain other contractual arrangements at the sole discretion of the Company, for which the compensatory element of the arrangement is deducted from the accumulated profits.

Effective January 1, 2008, current CIT Law imposes a 10% withholding income tax for dividends distributed by foreign invested enterprises to their immediate holding companies outside mainland China. A lower withholding tax rate will be applied if there is a tax treaty arrangement between mainland China and the jurisdiction of the foreign holding company. Distributions to holding companies in Hong Kong that satisfy certain requirements specified by PRC tax authorities, for example, will be subject to a 5% withholding tax rate. Furthermore, pursuant to the applicable circular and interpretations of the current EIT Law, dividends from earnings created prior to 2008 but distributed after 2008 are not subject to withholding income tax.

Earnings per share

In accordance with "Computation of Earnings Per Share", basic earnings per share is computed by dividing net income attributable to common shareholders by the weighted average number of common shares outstanding during the year. Diluted earnings per share is calculated by dividing net income attributable to common shareholders as adjusted for the effect of dilutive ordinary equivalent shares, if any, by the weighted average number of ordinary and dilutive ordinary equivalent shares outstanding during the year. Dilutive ordinary equivalent shares consist of ordinary shares issuable upon the exercise of outstanding share options (using the treasury stock method).

If the number of common shares outstanding increases as a result of a stock dividend or stock split or decreases as a result of a reverse stock split, the computations of basic and diluted EPS shall be adjusted retroactively for all periods presented to reflect that change in capital structure. If changes in common stock resulting from stock dividends, stock splits, or reverse stock splits occur after the close of the period but before the financial statements are issued or are available to be issued, the per-share computations for those and any prior-period financial statements presented are based on the new number of shares.

Effective December 1, 2015, the Company effected a change of the ratio of its ADSs to ordinary shares from four (4) ADSs representing one (1) ordinary share to eight (8) ADSs representing one (1) ordinary share. The historical and present earnings/ (loss) per share for the periods presented herein has been retrospectively adjusted to reflect such effect.

Treasury stock

On July 30, 2008 and September 30, 2008 our board of directors and shareholders respectively approved a US$15 million share repurchase plan. On September 29, 2011, our board of directors approved another US$100 million share repurchase plan. On June 13, 2012, our board of directors approved a US$300 million share repurchase plan. And on April 3, 2014, our board of directors approved a US$600 million share repurchase plan. The share-repurchase programs do not require the Company to acquire a specific number of shares and may be suspended or discontinued at any time.

Segment reporting

The Company operates and manages its business as a single segment. Resources are allocated and performance is assessed by the CEO, whom is determined to be the Chief Operating Decision Maker (CODM). Since the Company operates in one reportable segment, all financial segment and product information required by this statement can be found in the Consolidated Financial Statements.

The Company primarily generates its revenues from end users in Great China Area, and assets of the Company are also located in Great China Area. Accordingly, no geographical segments are presented.

Recent accounting pronouncements

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606) ("ASU 2014-09"). ASU 2014-09 supersedes the revenue recognition requirements in ASC Topic 605, Revenue Recognition, and most industry-specific guidance. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The new standard will require the Company to separate performance obligations within a contract, determine total transaction costs, and ultimately allocate the transaction costs across the established performance obligations. In August 2015, the FASB issued ASU No. 2015-14, "Revenue from Contracts with Customers" (Topic 606): Deferral of the Effective Date, which delays the effective date of ASU 2014-09 by one year. As a result, ASU 2014-09 will become effective for the Company beginning in fiscal 2018 under either full or modified retrospective adoption, with early adoption permitted as of the original effective date of ASU 2014-09. The Company is currently assessing the potential effects of these changes on the Company's consolidated financial statements.

In January, 2016, the FASB issued ASU No. 2016-01, Recognition and Measurement of Financial Assets and Financial Liabilities. This accounting standard retains the current accounting for classifying and measuring investments in debt securities and loans, but requires equity investments to be measured at fair value with subsequent changes recognized in net income, except for those accounted for under the equity method or requiring consolidation. This guidance also changes the accounting for investments without a readily determinable fair value and that do not qualify for the practical expedient to estimate fair value. A policy election can be made for these investments whereby estimated fair value may be measured at cost and adjusted in subsequent periods for any impairment or changes in observable prices of identical or similar investments. This revised guidance is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The Company is in the process of evaluating the impact of the standard on its consolidated financial statements.

In February, 2016, the FASB issued ASU No. 2016-02, Leases. This accounting standard requires lessees to recognize assets and liabilities related to lease arrangements longer than 12 months on the balance sheet. This standard also requires additional disclosures by lessees and contains targeted changes to accounting by lessors. The updated guidance is effective for interim and annual periods beginning after December 15, 2018, and early adoption is permitted. The recognition, measurement, and presentation of expenses and cash flows arising from a lease by a lessee have not significantly changed from previous GAAP. The Company is in the process of evaluating the impact of the standard on its consolidated financial statements.

In March, 2016, the FASB issued ASU No. 2016-06, Contingent Put and Call Options in Debt Instruments. The amendments in this Update apply to all entities that are issuers of or investors in debt instruments (or hybrid financial instruments that are determined to have a debt host) with embedded call (put) options. The Amendments in this Update clarify the requirements for assessing whether contingent call (put) options that can accelerate the payment of principal on debt instruments are clearly and closely related to their debt hosts, which is one of the criteria for bifurcating an embedded derivative. An entity performing the assessment under the amendments in this Update is required to assess the embedded call (put) options solely in accordance with the four-step decision sequence. Consequently, when a call (put) option is contingently exercisable, an entity does not have to assess whether the event that triggers the ability to exercise a call (put) option is related to interest rates or credit risks. The amendments are an improvement to GAAP because they eliminate diversity in practice in assessing embedded contingent call (put) options in debt instruments. For public companies, the amendments in this Update are effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. An entity should apply the amendments in this Update on a modified retrospective basis to existing debt instruments as of the beginning of the fiscal year for which the amendments are effective. The Company is in the process of evaluating the impact of the Update on its consolidated financial statements.

In March 2016, the FASB issued ASU No. 2016-07, Simplifying the Transition to the Equity Method of Accounting. The amendments in this Update eliminate the requirement that when an investment qualified for use of the equity method as a result of an increase in the level of ownership interest or degree of influence, an investor must adjust the investment, results of operations, and retained earnings retroactively on a step-by-step basis as if the equity method had been in effect during all previous periods that the investment had been held. The amendments require that the equity method investor add the cost of acquiring the additional interest in the investee to the current basis of the investor's previous held interest and adopt the equity method of accounting as of the date the investment becomes qualified for equity method accounting. Therefore, upon qualifying for the equity method of accounting, no retroactive adjustment of the investment is required. The amendments in this Update require that an entity that has an available-for-sale equity security that becomes qualified for the equity method of accounting recognize through earnings the unrealized holding gain or loss in accumulated other comprehensive income at the date the investment becomes qualified for use of the equity method. The amendments in this Update are effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016. The amendments should be applied prospectively upon their effective date to increase in the level of ownership interest or degree of influence that result in the adoption of the equity method. Earlier application is permitted. The Company is in the process of evaluating the impact of the Update on its consolidated financial statements.

In March 2016, the FASB issued ASU 2016-09, Compensation—Stock Compensation (Topic 718): Improvements to Employee Share—Based Payment Accounting, which outlines new provisions intended to simplify various aspects related to accounting for share—based payments and their presentation in the financial statements. The standard is effective for the Company from calendar 2017 and from the first interim period of calendar 2017. Early adoption is permitted. The Company is evaluating the impact of the adoption of this update and, based upon consideration of its share—based payment practices, does not expect that the adoption will have a material impact on its consolidated financial statements.

In June 2016, the FASB issued ASU 2016-13, Financial Instruments—Credit Losses (Topic 326), Measurement of Credit Losses on Financial Statements. This ASU requires a financial asset (or group of financial assets) measured at amortized cost basis to be presented at the net amount expected to be collected. The allowance for credit losses is a valuation account that is deducted from the amortized cost basis of the financial asset(s) to present the net carrying value at the amount expected to be collected on the financial asset. The standard is effective for the Company from calendar 2020, with early adoption permitted for calendar 2019. The Company has yet to commence an evaluation of the impact of the adoption of this standard on its consolidated financial statements.

Certain risks and concentration

Financial instruments that potentially subject the Company to significant concentrations of credit risk consist primarily of cash and cash equivalents, restricted cash, short-term investment, accounts receivable, amounts due from related parties, prepayments and other current assets. As of December 31, 2015 and June 30, 2016, substantially all of the Company's cash and cash equivalents, restricted cash and short-term investment were held in major financial institutions located in the PRC and in Hong Kong, which management considers to be of high credit quality based on their credit ratings. Accounts receivable are generally unsecured and denominated in RMB, and are derived from revenues earned from operations arising primarily in the PRC.

No individual customer accounted for more than 10% of net revenues for the six-month period ended June 30, 2015 and 2016. No individual customer accounted for more than 10% of accounts receivable as of December 31, 2015 and June 30, 2016.

Available-for-sale investments

China Eastern Airlines Limited ("China Eastern Airlines")

In April 2016, the Company purchased 466 million ordinary share of China Eastern Airlines with the total consideration of RMB 3 billion which represented around 3% equity interest of China Eastern Airlines. China Eastern Airlines is listed on the New York, Hong Kong and Shanghai stock exchange. The shares of China Eastern Airlines the Company purchased is traded at Shanghai Stock Exchange. The Company does not have the ability to exercise significant influence. The investment in China Eastern Airlines is therefore classified as available-for-sale investment.

In July, 2015, after Series D+ financing of Tujia, the equity interest of the Company was diluted to 45% and the Company was no longer entitled to appoint the majority of the board of directors of Tujia. As a result, the Company lost the control in Tujia and the financial position and results of operations of Tujia was deconsolidated. As of June 30, 2016, the Company held 101,498,094 convertible and redeemable preferred shares of Tujia.

("eLong") which included both ordinary shares and high-vote ordinary shares. The total consideration was approximately USD422 million. The Company has one out of eight board seats of eLong. The Company applies the equity method to account for the investment starting June 2015.

In May 2016, in connection with a consummated "going-private" transaction of eLong, eLong was reorganized and became the wholly owned subsidiary of E-dragon Holdings Limited ("E-dragon"). All the ordinary shares and high-vote ordinary shares of eLong previously held by the Company were transferred to the ordinary shares and preferred shares of E-dragon respectively. The Company disposed its previously held investment in eLong at its carrying value and recognized the ordinary shares and preferred shares of E-dragon it obtained at their respective fair value on the date of transfer. The Company determined that the fair value of the ordinary shares and preferred shares of E-dragon approximated to the carrying value of its investment in eLong.

After the transaction, the Company will apply equity accounting for its investment in E-dragon's ordinary shares, it acquired on the date of transfer, on one quarter lag basis since the financial statements of E-dragon were not available within a sufficient time period. The preferred shares of E-dragon that the Company holds are redeemable and convertible and hence not considered as in substance common stocks and are classified as available-for-sale debt security.

(a)

On June 1, 2015, Qunar and Baidu entered into a business cooperation agreement, under which Baidu agreed to grant Qunar an exclusive right to integrate its hotel information and products into the personal computer and mobile versions of Baidu Maps. Qunar will display location-based hotel data through the Baidu Maps interface. Users can click on the displayed hotels to view hotels and to complete bookings. Qunar pays Baidu service commission at a certain percentage of gross revenue Qunar earns in exchange for the services provided by Baidu. This agreement expired in May 2016 subject to renewal negotiation between both parties. As of December 31, 2015 and June 30, 2016, the outstanding balance related to business cooperation agreement amounted to RMB 138 million and RMB 429 million respectively.

On February 27, 2014, Qunar obtained a revolving credit facility of US$300,000,000 from Baidu. The three-year credit facility bears no commitment fee. Any drawdown bears interest at a rate of 90% of the benchmark lending rate published by the People's Bank of China and shall be repaid within three years from the drawdown date. Qunar is allowed to repay its outstanding debt obligation at maturity either by cash or by issuance of Class B shares. The applicable share conversion price will be determined by the prevailing share price at the maturity date. On March 12 and May 4, 2015, Qunar drew down RMB507 million (US$78 million) and RMB627 million (US$97 million) respectively from the credit facility. In March 2016, Qunar repaid these loans and the facility agreement was terminated. The repayment was reported in "Repayment of loans due to related parties" in the statement of cash flow.

On October 27, 2015, Qunar granted a loan amounting to RMB650 million (US$100 million) to Baidu. The loan bore an interest at 1.00% with a repayment term of 12 months. As of December 31, 2015, the outstanding entrusted loan and interest to Baidu amounted to RMB 651 million. Qunar received the repayment in March, 2016. In connection with the loan granted to Baidu, Qunar was granted a loan amounting to RMB640 million (US$99 million) from Baidu Times. The loan bore an interest at 4.14% with a repayment term of 12 months. Qunar repaid the loan in March, 2016. The Company had evaluated both substance and form of these loans arrangements with Baidu. Given that the loan granted to Baidu is solely for the consideration the currency access to RMB and is also dependent on the receipt of the loan provided by Baidu, and also taking into account of the significant net cash in flow as a result of all the loans arrangements with Baidu during the periods, the Company believes these arrangements have the primary purpose and intent in common to finance Qunar and therefore are reported as financing activities in the statement of cash flow on a gross basis according to the forms of the arrangements.

The PRC

The Company's subsidiaries and VIEs registered in the PRC are subject to PRC Corporate Income Tax ("CIT") on the taxable income as reported in their respective statutory financial statements adjusted in accordance with relevant PRC income tax laws.

The PRC CIT laws apply a general enterprise income tax rate of 25% to both foreign-invested enterprises and domestic enterprises. Preferential tax treatments are granted to enterprises, which conduct business in certain encouraged sectors and to enterprises otherwise classified as a High and New Technology Enterprise ("HNTE"). Being qualified as HNTE, Ctrip Computer Technology, Ctrip Travel Information and Ctrip Travel Network are entitled to a preferential CIT rate of 15% from 2014 to 2016 and JointWisdom is entitled to a preferential CIT rate of 15% from 2015 to 2017.

In 2012, Chengdu Ctrip and Chengdu Ctrip International obtained approval from local tax authorities to apply the 15% preferential tax rate from 2012 to 2015 as qualified as Enterprises falling within the Catalog of Encouraged Industries in the Western Region ("Old Catalog"). In 2013, Chengdu Information Technology Co., Ltd. ("Chengdu Information") obtained approval from local tax authorities to apply the 15% tax rate from 2013 to 2016. In 2014, a new Catalog of Encouraged Industries in the Western Region ("New Catalog") has been released. Under the "New Catalog", these subsidiaries may apply the 15% rate for CIT filing upon agreement by the in-charge tax authorities.

Pursuant to the PRC CIT Law, all foreign invested enterprises in the PRC are subject to the withholding tax for their earnings generated after January 1, 2008. The Company expects to indefinitely reinvest undistributed earnings generated after January 1, 2008 in the onshore PRC entities. As a result, no deferred tax liability was provided on the outside basis difference from undistributed earnings after January 1, 2008.

Composition of income tax expense

The current and deferred portion of income tax expense included in the consolidated statements of income for the six-month period ended June 30, 2015 and 2016 were as follows:

	Six-month period ended June 30, 2015			Six-month period ended June 30, 2016
	RMB			RMB
Current income tax expense		122,438,605			254,836,226
Deferred tax benefit		(84,826,416	)		(108,320,437	)

Income tax expense		37,612,189			146,515,789

Income tax expense was RMB147 million in the six-month period ended June 30, 2016, increase from RMB 38 million in the same period in 2015. The effective income tax rate in six-month period ended June 30, 2016 and 2015 were –7.7% and –104.8% respectively, the flux was mainly attributable to the change of non-deductible share based compensation expenses as well as the valuation allowance provided in the respective periods.

As of December 31, 2015 and June 30, 2016, valuation allowance of RMB31 million and RMB55 million was provided for operating loss carry forwards related to certain subsidiary based on then assessment where it is more likely than not that such deferred tax assets will not be realized. If events were to occur in the future that would allow us to realize more of our deferred tax assets than the presently recorded net amount, an adjustment would be made to the deferred tax assets that would increase income for the period when those events occurred.

As of June 30, 2016, the Group had net operating tax loss carry forwards amounted to RMB2.1 billion which will expire from 2016 to 2019 if not used.

The provisions for income taxes for the six-month period ended June 30, 2015 and 2016 differ from the amounts computed by applying the CIT primarily due to preferential tax rate enjoyed by certain of the Company's subsidiaries and VIEs in the PRC.

The following table sets forth the effect of preferential tax on China operations:

	Six-month period end June 30, 2015		Six-month period end June 30, 2016
	RMB		RMB
Tax holiday effect		46,395,517		28,535,766

Description of 2017 Convertible Senior Notes

On September 24, 2012, the Company issued US$180 million in aggregate principle amount of 0.5% Convertible Senior Notes due September 15, 2017 (the "2017 Notes") at par. The 2017 Notes may be converted, under certain circumstances, based on an initial conversion rate of 51.7116 American depository shares ("ADS") per US$1,000 principal amount of the 2017 Notes (which represents an initial conversion price of US$19.34 per ADS).

The net proceeds to the Company from the issuance of the 2017 Notes were US$175 million. The Company pays cash interest at an annual rate of 0.5% on the 2017 Notes, payable semi-annually in arrears on March 15 and September 15 of each year, beginning March 15, 2013. Debt issuance costs were US$5.4 million and are being amortized to interest expense to the first put date of the 2017 Notes (September 15, 2015).

The 2017 Notes are general senior unsecured obligations and rank (1) senior in right of payment to any of the Company's future indebtedness that is expressly subordinated in right of payment to the 2017 Notes, (2) equal in right of payment to any of the Company's future indebtedness and other liabilities of the Company that are not so subordinated, (3) junior in right of payment to any of the Company's secured indebtedness to the extent of the value of the assets securing such indebtedness and (4) structurally junior to all future indebtedness incurred by the Company's subsidiaries and their other liabilities (including trade payables).

Concurrently with the issuance of the 2017 Notes, the Company purchased a call option ("Purchased Call Option") and sold warrants ("Sold Warrants"). The separate Purchased Call Option and Sold Warrants are structured to reduce the potential future economic dilution associated with the conversion of the 2017 Notes and to increase the initial conversion price to US$26.37 per ADS. Each of these components is discussed separately below:

Purchase Call Option

Counterparty agreed to sell to the Company up to approximately 9.3 million shares of the Company's ADS, which is the number of ADS initially issuable upon conversion of the 2017 Notes in full, at a price of US$19.34 per ADS. The Purchased Call Option will be settled by the counterparty in ADSs and will terminate upon the maturity date of the 2017 Notes. Settlement of the Purchased Call Option in ADSs, based on the number of ADSs issued upon conversion of the 2017 Notes, on the expiration date would result in the Company receiving shares equivalent to the number of shares issuable by the Company upon conversion of the 2017 Notes. Should there be an early termination of the Purchased Call Option, the number of ADSs potentially received by the Company will depend upon 1) the then existing overall market conditions, 2) the Company's stock price, 3) the volatility of the Company's stock, and 4) the amount of time remaining before expiration of the convertible note hedge.

Sold Warrants

The Company received US$26.6 million from the same counterparty from the sale of warrants to purchase up to approximately 9.3 million shares of the Company's ADS at an exercise price of US$26.37 per ADS. The warrants had an expected life of 5 years and expire on September 15, 2017. At expiration, the Company may, at its option, elect to settle the warrants on a net share basis. As of June 30, 2016, the warrants had not been exercised and remained outstanding.

Use of Proceeds

The Company used a portion of the net proceeds of the offering to pay the associated cost of the convertible note hedge transaction, after such cost is partially offset by the proceeds to the Company from the sale of the warrant transaction. The remainder of the net proceeds from this offering is planned to be used for other general corporate purposes, including working capital needs and potential acquisitions of complementary businesses, as well as potential ADS repurchases and note retirement from time to time.

Evaluation that transactions should be viewed as a single unit:

In accordance with ASC 815-10-15, the Company concluded that the offering of the 2017 Notes, Purchased Call Option and the Issued Warrants (1) do not entail the same risks as the 2017 Notes involve interest, credit and equity risks, whereas the Purchased Call Option and Issued Warrants transaction was intended to reduce the equity dilution risk for the Company and (2) have a valid business purpose and economic need for structuring the transactions separately as the Company wanted to mitigate future dilution upon conversion of the 2017 Notes, as such required that the purchased call option is an American style option which is physical settled whereas the warrant is a European style instrument that allows net share settlement or cash settlement at the choice of the Company. Therefore, the offering of the 2017 Notes, Purchased Call Option and Issued Warrants transactions should be accounted for as separate transactions.

The Company has accounted for the 2017 Notes in accordance with ASC 470, as a single instrument as a long-term debt. The value of the 2017 Notes is measured by the cash received. As of December 31, 2015, RMB325 million (US$50 million) is reclassified as short-term debt to present the 2017 Notes may be redeemed within one year (Note 12).

The key terms of the 2017 Notes are as follows:

Redemption

Contingent redemption option

The 2017 Notes are not redeemable prior to the maturity date of September 15, 2017, except as described below. The holders of the 2017 Notes (the "Holders") have a non-contingent option to require the Company to repurchase for cash all or any portion of their 2017 Notes on September 15, 2015. The repurchase price will equal 100% of the principal amount of the 2017 Notes to be repurchased plus accrued and unpaid interest, if any, to, but excluding, the repurchase date. If a fundamental change (as defined in the Indenture) occurs prior to the maturity date, the Holders may require the Company to purchase for cash all or any portion of the 2017 Notes at a purchase price equal to 100% of the principal amount of the 2017 Notes to be purchased plus accrued and unpaid interest, if any, to, but excluding, the fundamental change purchase date. The Holders have the option to require the Company to repurchase the 2017 Notes, in whole or in part, in the event of a fundamental change for an amount equal to the 100% of the principal amount and any accrued and unpaid interest in the event of fundamental changes. The Company believes that the likelihood of occurrence of events considered a fundamental change is remote.

The contingent redemption option is assessed in accordance with ASC 815-15-25-42. The contingent redemption option is considered clearly and closely related to its debt host and does not meet the requirement for bifurcation as the 2017 Notes were issued at par and the repurchase feature requires the issuer to settle the option by delivering par plus accrued and unpaid interest, the 2017 Notes holder would recover all of their initial investment. Additionally, since the 2017 Notes holder can only recover its initial investment upon exercise of its option, there are no interest rate scenarios under which the embedded derivative would at least double the investor's initial rate of return.

Non-contingent redemption option

On or after September 15, 2015 (after year 3), the Holders have the right to require the issuer to redeem, at 100% of the loan's principal amount plus accrued and unpaid interest, in which circumstance the Holders would recover substantially all of their initial investment.

Since the Holders can only recover its initial investment upon exercise of its option, there are no interest rate scenarios under which the embedded derivative would at least double the investor's initial rate of return. Therefore, the embedded repurchase feature (put option) is considered clearly and closely related to the debt host pursuant to ASC 815-15-25-1 and does not meet the requirements for bifurcation.

Conversion

The Holders may convert their 2017 Notes in integral multiples of US$1,000 principle amount at an initial conversion rate of US$19.34 per ADS, at any time prior to the maturity date of September 15, 2017. Upon conversion of the 2017 Notes, the Company will deliver shares of the Company's ADS. The conversion rate is subject to adjustment in certain events, such as distribution of dividends and stock splits. In addition, upon a make-whole fundamental change (as defined in the Indenture), the Company will, under certain circumstances, increase the applicable conversion rate for a holder that elects to convert its 2017 Notes in connection with such make-whole fundamental change.

In accordance with ASC 815-10-15-83, the conversion option meets the definition of a derivative. However, bifurcation of conversion option from the 2017 Notes is not required as the scope exception prescribed in ASC 815-10-15-74 is met as the conversion option is considered indexed to the entity's own stock and classified in stockholders' equity.

Early conversion of 2017 Convertible Senior Notes

The Company offered the public tranche of the 2017 Notes holders to convert their 2017 Notes early, through an inducement. The inducement we offered included the original term's ratio for ADS conversion plus a cash incentive of 1.5%-2.0%. As a result of the inducement, for six-month period ended June 30, 2015 and 2016, US$4.3 million and US$15.8 million of the 2017 Notes was tendered, respectively, or 0.4 million ADS and 1 million ADS at the initial conversion rate of 51.7116 ADS per note, respectively. These conversions did not materially impact the current shares outstanding.

Early termination of Call Option

The above early conversion of 2017 Convertible Senior Notes also resulted in an early termination of a call option we entered into during 2012, of which the Company has received US$ 11.6 million from this early termination.

Description of 2018 Convertible Senior Notes

On October 17, 2013, the Company issued US$800 million in aggregate principle amount of 1.25% Convertible Senior 2018 Notes due October 15, 2018 (the "2018 Notes") at par. The 2018 Notes may be converted, under certain circumstances, based on an initial conversion rate of 12.7568 American depository shares ("ADS") per US$1,000 principal amount of the 2018 Notes (which represents an initial conversion price of US$78.39 per ADS).

The net proceeds to the Company from the issuance of the 2018 Notes were US$780 million. The Company pays cash interest at an annual rate of 1.25% on the 2018 Notes, payable semi-annually in arrears on April 15 and October 15 of each year, beginning April 15, 2014. Debt issuance costs were US$19.6 million and are being amortized to interest expense to the maturity date of the 2018 Notes (October 15, 2018).

The 2018 Notes are general senior unsecured obligations and rank (1) senior in right of payment to any of the Company's future indebtedness that is expressly subordinated in right of payment to the 2018 Notes, (2) equal in right of payment to any of the Company's future indebtedness and other liabilities of the Company that are not so subordinated, (3) junior in right of payment to any of the Company's secured indebtedness to the extent of the value of the assets securing such indebtedness and (4) structurally junior to all future indebtedness incurred by the Company's subsidiaries and their other liabilities (including trade payables).

Concurrently with the issuance of the 2018 Notes, the Company purchased a call option ("Purchased Call Option") and sold warrants ("Sold Warrants"). The separate Purchased Call Option and Sold Warrants are structured to reduce the potential future economic dilution associated with the conversion of the 2018 Notes and to increase the initial conversion price to US$96.27 per ADS. Each of these components is discussed separately below:

Purchase Call Option

Counterparty agreed to sell to the Company up to approximately 10.2 million shares of the Company's ADS, which is the number of ADS initially issuable upon conversion of the 2018 Notes in full, at a price of US$78.39 per ADS. The Purchased Call Option will be settled in ADSs and will terminate upon the maturity date of the 2018 Notes. Settlement of the Purchased Call Option in ADSs, based on the number of ADSs issued upon conversion of the 2018 Notes, on the expiration date would result in the Company receiving shares equivalent to the number of shares issuable by the Company upon conversion of the 2018 Notes. Should there be an early termination of the Purchased Call Option, the number of ADSs potentially received by the Company will depend upon 1) the then existing overall market conditions, 2) the Company's stock price, 3) the volatility of the Company's stock, and 4) the amount of time remaining before expiration of the convertible note hedge.

Sold Warrants

The Company received US$77.2 million from the same counterparty from the sale of warrants to purchase up to approximately 10.2 million shares of the Company's ADS at an exercise price of US$96.27 per ADS. The warrants had an expected life of 5 years and expire on October 15, 2018. At expiration, the Company may, at its option, elect to settle the warrants on a net share basis. As of December 31, 2015, the warrants had not been exercised and remained outstanding.

Use of Proceeds

Evaluation that transactions should be viewed as a single unit:

In accordance with ASC 815-10-15, the Company concluded that the offering of the 2018 Notes, Purchased Call Option and the Issued Warrants (1) do not entail the same risks as the 2018 Notes involve interest, credit and equity risks, whereas the Purchased Call Option and Issued Warrants transaction was intended to reduce the equity dilution risk for the Company and (2) have a valid business purpose and economic need for structuring the transactions separately as the Company wanted to mitigate future dilution upon conversion of the 2018 Notes, as such required that the purchased call option is an American style option which is physical settled whereas the warrant is a European style instrument that allows net share settlement or cash settlement at the choice of the Company. Therefore, the offering of the 2018 Notes, Purchased Call Option and Issued Warrants transactions should be accounted for as separate transactions.

The Company has accounted for the 2018 Notes in accordance with ASC 470, as a single instrument as a long-term debt. The value of the 2018 Notes is measured by the cash received. As of December 31, 2015, RMB5.2 billion (US$800 million) is reclassified as short-term debt to present the 2018 Notes may be redeemed within one year (Note 12)

The key terms of the 2018 Notes are as follows:

Redemption

Contingent redemption option

The 2018 Notes are not redeemable prior to the maturity date of October 15, 2018, except as described below. The holders of the 2018 Notes (the "Holders") have a non-contingent option to require the Company to repurchase for cash all or any portion of their 2018 Notes on October 15, 2016. The repurchase price will equal 100% of the principal amount of the 2018 Notes to be repurchased plus accrued and unpaid interest, if any, to, but excluding, the repurchase date. If a fundamental change (as defined in the Indenture) occurs prior to the maturity date, the Holders may require the Company to purchase for cash all or any portion of the 2018 Notes at a purchase price equal to 100% of the principal amount of the 2018 Notes to be purchased plus accrued and unpaid interest, if any, to, but excluding, the fundamental change purchase date. The Holders have the option to require the Company to repurchase the 2018 Notes, in whole or in part, in the event of a fundamental change for an amount equal to the 100% of the principal amount and any accrued and unpaid interest in the event of fundamental changes. The Company believes that the likelihood of occurrence of events considered a fundamental change is remote.

The contingent redemption option is assessed in accordance with ASC 815-15-25-42. The contingent redemption option is considered clearly and closely related to its debt host and does not meet the requirement for bifurcation as the 2018 Notes were issued at par and the repurchase feature requires the issuer to settle the option by delivering par plus accrued and unpaid interest, the 2018 Notes holder would recover all of their initial investment. Additionally, since the 2018 Notes holder can only recover its initial investment upon exercise of its option, there are no interest rate scenarios under which the embedded derivative would at least double the investor's initial rate of return.

Non-contingent redemption option

On or after October 15, 2016 (after year 3), the Holders have the right to require the issuer to redeem, at 100% of the loan's principal amount plus accrued and unpaid interest, in which circumstance the Holders would recover substantially all of their initial investment.

Conversion

The Holders may convert their 2018 Notes in integral multiples of US$1,000 principle amount at an initial conversion rate of US$78.39 per ADS, at any time prior to the maturity date of October 15, 2018. Upon conversion of the 2018 Notes, the Company will deliver shares of the Company's ADS. The conversion rate is subject to adjustment in certain events, such as distribution of dividends and stock splits. In addition, upon a make-whole fundamental change (as defined in the Indenture), the Company will, under certain circumstances, increase the applicable conversion rate for a holder that elects to convert its 2018 Notes in connection with such make-whole fundamental change.

In accordance with ASC 815-10-15-83, the conversion option meets the definition of a derivative. However, bifurcation of conversion option from the 2018 Notes is not required as the scope exception prescribed in ASC 815-10-15-74 is met as the conversion option is considered indexed to the entity's own stock and classified in stockholders' equity.

Assessment of Beneficial Conversion Feature and Contingent Beneficial Conversion Feature:

As the conversion options are not bifurcated, the Company has assessed the beneficial conversion feature ("BCF"), as of commitment date as defined in ASC 470-20. There was no BCF attribute to the 2018 Notes as the set conversion price for the 2018 Notes was greater than the fair value of the ordinary share price at date of issuance.

The Holders have the option to convert upon a fundamental change, if Holders decide to convert in connection with a fundamental change; the number of shares issuable upon conversion will be increased. The Company will have to assess for the contingent BCF using a measurement date upon issuance of the 2018 Notes, upon occurrence of such adjustment. The settlement of the conversion is based on a make-whole provision resulting from a fundamental change, this feature is consistent with ASC 815-40-55-46 (example 19), therefore the Company concludes that this feature is also considered indexed to its own stock.

Accounting for Debt Issuance Costs:

The debt issuance costs were recorded as reduction to the long term debt and are amortized as interest expense, using the effective interest method, over the term of the 2018 Notes.

Accounting for Purchased Call Option:

In accordance with ASC 815-10-15-83, the Purchased Call Option meets the definition of a derivative instrument. However, the scope exception in accordance with ASC 815-10-15-74 applies to the Purchased Call Option as it is indexed to its own stock, and the Purchased Call Option meets the requirements of ASC 815 and would be classified in stockholders' equity, therefore, the cost paid for Purchased Call Option was accounted for within stockholders' equity, and subsequent changes in fair value will not be recorded.

Accounting for Issued Warrants:

The Company assessed that the Issued Warrants are not liabilities within scope of ASC 480-10-25. The Issued Warrants are legally detachable from the 2018 Notes and Purchased Call Option and separately exercisable as such meets the definition of a freestanding derivative instrument pursuant to ASC 815. However, the scope exception in accordance with ASC 815-10-15-74 applies to Warrants and it meets the requirements of ASC 815 that would be classified in stockholders' equity. Therefore, the Warrants were initially accounted for within stockholders' equity, and subsequent changes in fair value will not be recorded.

Description of 2020 Convertible Senior Notes

On June 18, 2015, the Company issued US$700 million in aggregate principle amount of 1.00% Convertible Senior 2020 Notes due July 1, 2020 (the "2020 Notes") at par. The 2020 Notes may be converted, under certain circumstances, based on an initial conversion rate of 9.1942 American depository shares ("ADS") per US$1,000 principal amount of the 2020 Notes (which represents an initial conversion price of US$108.76 per ADS).

The net proceeds to the Company from the issuance of the 2020 Notes were US$689 million. The Company pays cash interest at an annual rate of 1.00% on the 2020 Notes, payable semi-annually in arrears on January 1 and July 1 of each year, beginning January 1, 2016. Debt issuance costs were US$11.3 million and are being amortized to interest expense to the maturity date of the 2020 Notes (July 1, 2020).

The 2020 Notes are general senior unsecured obligations and rank (1) senior in right of payment to any of the Company's future indebtedness that is expressly subordinated in right of payment to the 2020 Notes, (2) equal in right of payment to any of the Company's future indebtedness and other liabilities of the Company that are not so subordinated, (3) junior in right of payment to any of the Company's secured indebtedness to the extent of the value of the assets securing such indebtedness and (4) structurally junior to all future indebtedness incurred by the Company's subsidiaries and their other liabilities (including trade payables).

Concurrently with the issuance of the 2020 Notes, the Company purchased a call option ("Purchased Call Option") and sold warrants ("Sold Warrants"). The separate Purchased Call Option and Sold Warrants are structured to reduce the potential future economic dilution associated with the conversion of the 2020 Notes and to increase the initial conversion price to US$135.02 per ADS. Each of these components is discussed separately below:

Purchase Call Option

Counterparty agreed to sell to the Company up to approximately 6.4 million shares of the Company's ADS, which is the number of ADS initially issuable upon conversion of the 2020 Notes in full, at a price of US$108.76 per ADS. The Purchased Call Option will be settled in ADSs and will terminate upon the maturity date of the 2020 Notes. Settlement of the Purchased Call Option in ADSs, based on the number of ADSs issued upon conversion of the 2020 Notes, on the expiration date would result in the Company receiving shares equivalent to the number of shares issuable by the Company upon conversion of the 2020 Notes. Should there be an early termination of the Purchased Call Option, the number of ADSs potentially received by the Company will depend upon 1) the then existing overall market conditions, 2) the Company's stock price, 3) the volatility of the Company's stock, and 4) the amount of time remaining before expiration of the convertible note hedge.

Sold Warrants

The Company received US$84.4 million from the same counterparty from the sale of warrants to purchase up to approximately 6.4 million shares of the Company's ADS at an exercise price of US$135.02 per ADS. The warrants had an expected life of 5 years and expire on July 1, 2020. At expiration, the Company may, at its option, elect to settle the warrants on a net share basis. As of December 31, 2015, the warrants had not been exercised and remained outstanding.

Use of Proceeds

Evaluation that transactions should be viewed as a single unit:

In accordance with ASC 815-10-15, the Company concluded that the offering of the 2020 Notes, Purchased Call Option and the Issued Warrants (1) do not entail the same risks as the 2020 Notes involve interest, credit and equity risks, whereas the Purchased Call Option and Issued Warrants transaction was intended to reduce the equity dilution risk for the Company and (2) have a valid business purpose and economic need for structuring the transactions separately as the Company wanted to mitigate future dilution upon conversion of the 2020 Notes, as such required that the purchased call option is an American style option which is physical settled whereas the warrant is a European style instrument that allows net share settlement or cash settlement at the choice of the Company. Therefore, the offering of the 2020 Notes, Purchased Call Option and Issued Warrants transactions should be accounted for as separate transactions.

The Company has accounted for the 2020 Notes in accordance with ASC 470, as a single instrument as a long-term debt. The value of the 2020 Notes is measured by the cash received. As of December 31, 2015, RMB4.5 billion (US$700 million) is accounted as the value of the 2020 Notes in long-term debt.

The key terms of the 2020 Notes are as follows:

Redemption

Contingent redemption option

The 2020 Notes are not redeemable prior to the maturity date of July 1, 2020, except as described below. The holders of the 2020 Notes (the "Holders") have a non-contingent option to require the Company to repurchase for cash all or any portion of their 2020 Notes on July 1, 2018. The repurchase price will equal 100% of the principal amount of the 2020 Notes to be repurchased plus accrued and unpaid interest, if any, to, but excluding, the repurchase date. If a fundamental change (as defined in the Indenture) occurs prior to the maturity date, the Holders may require the Company to purchase for cash all or any portion of the 2020 Notes at a purchase price equal to 100% of the principal amount of the 2020 Notes to be purchased plus accrued and unpaid interest, if any, to, but excluding, the fundamental change purchase date. The Holders have the option to require the Company to repurchase the 2020 Notes, in whole or in part, in the event of a fundamental change for an amount equal to the 100% of the principal amount and any accrued and unpaid interest in the event of fundamental changes. The Company believes that the likelihood of occurrence of events considered a fundamental change is remote.

The contingent redemption option is assessed in accordance with ASC 815-15-25-42. The contingent redemption option is considered clearly and closely related to its debt host and does not meet the requirement for bifurcation as the 2020 Notes were issued at par and the repurchase feature requires the issuer to settle the option by delivering par plus accrued and unpaid interest, the 2020 Notes holder would recover all of their initial investment. Additionally, since the 2020 Notes holder can only recover its initial investment upon exercise of its option, there are no interest rate scenarios under which the embedded derivative would at least double the investor's initial rate of return.

Non-contingent redemption option

On or after July 1, 2018 (after year 3), the Holders have the right to require the issuer to redeem, at 100% of the loan's principal amount plus accrued and unpaid interest, in which circumstance the Holders would recover substantially all of their initial investment.

Conversion

The Holders may convert their 2020 Notes in integral multiples of US$1,000 principle amount at an initial conversion rate of US$108.76 per ADS, at any time prior to the maturity date of July 1, 2020. Upon conversion of the 2020 Notes, the Company will deliver shares of the Company's ADS. The conversion rate is subject to adjustment in certain events, such as distribution of dividends and stock splits. In addition, upon a make-whole fundamental change (as defined in the Indenture), the Company will, under certain circumstances, increase the applicable conversion rate for a holder that elects to convert its 2020 Notes in connection with such make-whole fundamental change.

In accordance with ASC 815-10-15-83, the conversion option meets the definition of a derivative. However, bifurcation of conversion option from the 2020 Notes is not required as the scope exception prescribed in ASC 815-10-15-74 is met as the conversion option is considered indexed to the entity's own stock and classified in stockholders' equity.

Assessment of Beneficial Conversion Feature and Contingent Beneficial Conversion Feature:

As the conversion options are not bifurcated, the Company has assessed the beneficial conversion feature ("BCF"), as of commitment date as defined in ASC 470-20. There was no BCF attribute to the 2020 Notes as the set conversion price for the 2020 Notes was greater than the fair value of the ordinary share price at date of issuance.

The Holders have the option to convert upon a fundamental change, if Holders decide to convert in connection with a fundamental change; the number of shares issuable upon conversion will be increased. The Company will have to assess for the contingent BCF using a measurement date upon issuance of the 2020 Notes, upon occurrence of such adjustment. The settlement of the conversion is based on a make-whole provision resulting from a fundamental change, this feature is consistent with ASC 815-40-55-46 (example 19), therefore the Company concludes that this feature is also considered indexed to its own stock.

Accounting for Debt Issuance Costs:

The debt issuance costs were recorded as reduction to the long term debt and are amortized as interest expense, using the effective interest method, over the term of the 2020 Notes.

Accounting for Purchased Call Option:

Accounting for Issued Warrants:

The Company assessed that the Issued Warrants are not liabilities within scope of ASC 480-10-25. The Issued Warrants are legally detachable from the 2020 Notes and Purchased Call Option and separately exercisable as such meets the definition of a freestanding derivative instrument pursuant to ASC 815. However, the scope exception in accordance with ASC 815-10-15-74 applies to Warrants and it meets the requirements of ASC 815 that would be classified in stockholders' equity. Therefore, the Warrants were initially accounted for within stockholders' equity, and subsequent changes in fair value will not be recorded.

Description of 2025 Convertible Senior Notes

On June 18, 2015, the Company issued US$400 million in aggregate principle amount of 1.99% Convertible Senior Notes due July 1, 2025 (the "2025 Notes") at par. The 2025 Notes may be converted, under certain circumstances, based on an initial conversion rate of 9.3555 American depository shares ("ADS") per US$1,000 principal amount of the 2025 Notes (which represents an initial conversion price of US$106.89 per ADS).

The net proceeds to the Company from the issuance of the 2025 Notes were US$393 million. The Company pays cash interest at an annual rate of 1.99% on the 2025 Notes, payable semi-annually in arrears on January 1 and July 1 of each year, beginning January 1, 2016. Debt issuance costs were US$6.8 million and are being amortized to interest expense to the maturity date of the 2025 Notes (July 1, 2025).

The 2025 Notes are general senior unsecured obligations and rank (1) senior in right of payment to any of the Company's future indebtedness that is expressly subordinated in right of payment to the 2025 Notes, (2) equal in right of payment to any of the Company's future indebtedness and other liabilities of the Company that are not so subordinated, (3) junior in right of payment to any of the Company's secured indebtedness to the extent of the value of the assets securing such indebtedness and (4) structurally junior to all future indebtedness incurred by the Company's subsidiaries and their other liabilities (including trade payables).

Use of Proceeds

Evaluation that transactions should be viewed as a single unit:

In accordance with ASC 815-10-15, the Company concluded that the offering of the 2025 Notes, Purchased Call Option and the Issued Warrants (1) do not entail the same risks as the 2025 Notes involve interest, credit and equity risks, whereas the Purchased Call Option and Issued Warrants transaction was intended to reduce the equity dilution risk for the Company and (2) have a valid business purpose and economic need for structuring the transactions separately as the Company wanted to mitigate future dilution upon conversion of the 2025 Notes, as such required that the purchased call option is an American style option which is physical settled whereas the warrant is a European style instrument that allows net share settlement or cash settlement at the choice of the Company. Therefore, the offering of the 2025 Notes, Purchased Call Option and Issued Warrants transactions should be accounted for as separate transactions.

The Company has accounted for the 2025 Notes in accordance with ASC 470, as a single instrument as a long-term debt. The value of the 2025 Notes is measured by the cash received. As of December 31, 2015, RMB2.6 billion (US$400 million) is accounted as the value of the 2025 Notes in long-term debt.

The key terms of the 2025 Notes are as follows:

Redemption

Contingent redemption option

The 2025 Notes are not redeemable prior to the maturity date of July 1, 2025, except as described below. The holders of the 2025 Notes (the "Holders") have a non-contingent option to require the Company to repurchase for cash all or any portion of their 2025 Notes on July 1, 2020. The repurchase price will equal 100% of the principal amount of the 2025 Notes to be repurchased plus accrued and unpaid interest, if any, to, but excluding, the repurchase date. If a fundamental change (as defined in the Indenture) occurs prior to the maturity date, the Holders may require the Company to purchase for cash all or any portion of the 2025 Notes at a purchase price equal to 100% of the principal amount of the 2025 Notes to be purchased plus accrued and unpaid interest, if any, to, but excluding, the fundamental change purchase date. The Holders have the option to require the Company to repurchase the 2025 Notes, in whole or in part, in the event of a fundamental change for an amount equal to the 100% of the principal amount and any accrued and unpaid interest in the event of fundamental changes. The Company believes that the likelihood of occurrence of events considered a fundamental change is remote.

Non-contingent redemption option

On or after July 1, 2020 (after year 5), the Holders have the right to require the issuer to redeem, at 100% of the loan's principal amount plus accrued and unpaid interest, in which circumstance the Holders would recover substantially all of their initial investment.

The 2017 convertible senior notes, 2018 convertible senior notes, 2020 convertible senior notes, 2025 convertible senior notes and the Priceline convertible notes were not included in the computation of diluted EPS in the six-month period ended June, 30, 2016 because the inclusion of such instrument would be anti-dilutive.

For the six-month period ended June 30, 2015 and 2016, the Company had securities which could potentially dilute basic earnings per share in the future, which were excluded from the computation of diluted earnings per share as their effects would have been anti-dilutive.

Capital commitments

As of June 30, 2016, the Company had outstanding capital commitments totaling RMB86 million, which consisted of capital expenditures of property, equipment and software.

Guarantee

In connection with our air ticketing business, the Group is required by the Civil Aviation Administration of China, International Air Transport Association, and local airline companies to pay deposits in order to or to provide other guarantees obtain blank air tickets. As of June 30, 2016, the amount under these guarantee arrangements was approximately RMB892 million.

Based on historical experience and information currently available, we do not believe that it is probable that we will be required to pay any amount under these guarantee arrangements.

Contingencies

The Company is not currently a party to any pending material litigation or other legal proceeding or claims.

The Company is incorporated in Cayman Islands and is considered as a foreign entity under PRC laws. Due to the restrictions on foreign ownership of the air-ticketing, travel agency, advertising and internet content provision businesses, the Company conducts these businesses partly through various VIEs. These VIEs hold the licenses and approvals that are essential for the Company's business operations. In the opinion of the Company's PRC legal counsel, the current ownership structures and the contractual arrangements with these VIEs and their shareholders as well as the operations of these VIEs are in compliance with all existing PRC laws, rules and regulations. However, there may be changes and other developments in PRC laws and regulations. Accordingly, the Company cannot be assured that PRC government authorities will not take a view in the future contrary to the opinion of the Company's PRC legal counsel. If the current ownership structures of the Company and its contractual arrangements with VIEs were found to be in violation of any existing or future PRC laws or regulations, the Company may be required to restructure its ownership structure and operations in China to comply with changing and new Chinese laws and regulations.
