Basis of presentation

The accompanying consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“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. Actual results could materially differ from those estimates.

Consolidation

The 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 has adopted 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:

As of December 31, 2014, the Company has various agreements with its consolidated VIEs and VIEs’ subsidiaries, including loan agreements, exclusive technical consulting and services agreements, share pledge agreements, exclusive option agreements and other operating agreements.

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

Powers of Attorney: Each of the shareholders of our affiliated Chinese entities signed an irrevocable power of attorney to appoint Ctrip Computer Technology (Shanghai) Co., Ltd. or another wholly owned subsidiary of ours, as attorney-in-fact to vote, by itself or any other person to be designated at its discretion, on all matters of our affiliated Chinese entities. Each power of attorney will remain effective during the existence of the applicable affiliated Chinese entity. The Power of Attorney shall remain effective as long as the applicable affiliated Chinese entity exists, and the shareholders of our affiliated Chinese entities are not entitled to terminate or amend the terms of the Power of Attorneys without prior written consent from us.

Amended and Restated Technical Consulting and Services Agreement: Ctrip Computer Technology, Ctrip Travel Network and Ctrip Travel Information provide our affiliated Chinese entities with technical consulting and related services and staff training and information services. We also maintain their network platforms. In consideration for our services, our 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 2014, our affiliated Chinese entities paid Ctrip Computer Technology and Ctrip Travel Network a quarterly fee based on the number of air tickets sold and the number of packaged-tour products sold in the quarter, at an average rate from RMB2 (US$0.3) to RMB19 (US$3) per ticket and from RMB8 (US$1) to RMB58 (US$9) per person per tour. Although the service fees are typically determined based on the number of air tickets sold and packaged tour products sold, given the fact that the nominee shareholders of our 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 affiliated Chinese entities in the form of service fees. The services fees paid by all of our affiliated Chinese entities as a percentage of their total net income were 82.7%, 105.9% and 109.4% for the years ended December 31, 2012, 2013 and 2014. 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 affiliate Chinese entity.

Amended and Restated Share Pledge Agreements: The shareholders of our affiliated Chinese entities have pledged their respective equity interests in our affiliated Chinese entities as a guarantee for the performance of all the obligations under the other contractual arrangements, including payment by our affiliated Chinese entities of the technical and consulting services fees to us under the amended and restated technical consulting and services agreements, repayment of the business loan under the amended and restated business loan agreements and performance of obligations under the amended and restated exclusive option agreements, each agreement as described herein. In the event any of our affiliated Chinese entity breaches any of its obligations or any shareholder of our affiliated Chinese entities breaches his/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, 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 amended and restated share pledge agreements came into effect on the day when the respective pledgors became shareholders of our affiliated Chinese entities, and shall expire two years after the pledgor and the affiliated Chinese entities no longer undertake any obligations under the above-referenced agreements.

Amended and Restated Business Loan Arrangements: Under the amended and restated business loan agreements we entered into with the shareholders of our affiliated Chinese entities, we extended long-term business loans to these shareholders of our affiliated Chinese entities with the sole purpose of providing funds necessary for the capitalization or acquisition of our affiliated Chinese entities. These loan amounts were injected into the affiliated Chinese entities as capitals and cannot be accessed for any personal uses. The amended and restated business loan agreements shall remain effective until the parties have fully performed their respective obligations under the agreement, and the shareholders of our 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 affiliated Chinese entities, as described in the following paragraph, and the amended and restated business 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.

Amended and Restated Exclusive Option Agreements: As consideration for our entering into the amended and restated business loan agreements described above, each of the shareholders of our affiliated Chinese entities 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 our 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 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 our affiliated Chinese entities pursuant to the amended and restated business 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 affiliate Chinese entity.

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

In addition, the Company also enters into amended and restated technical consulting and services agreements with its majority or wholly owned subsidiaries of the affiliated Chinese entities, such as Chengdu Ctrip and Chengdu Ctrip International, and these subsidiaries pay the Company service fees based on the level of services provided. The existence of such amended and restated technical consulting and services agreements provides the Company with the enhanced ability to transfer economic benefits of these majority or wholly owned subsidiaries of the affiliated Chinese entities to us in exchange for the services provided, and this is in addition to the Company’s existing ability to consolidate and extract the economic benefits of these majority or wholly owned subsidiaries of the affiliated Chinese entities (for instance, the 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 the Company 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 RMB514 million as of December 31, 2014. 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.

As of December 31, 2013 and 2014, the VIEs’ assets mainly consisted of short-term investment (December 31, 2013: RMB1.6 billion, December 31, 2014: RMB 3.1 billion), cash and cash equivalent (December 31, 2013: RMB1.5 billion, December 31, 2014: RMB 2.6 billion), prepayments and other current assets (December 31, 2013: RMB912 million, December 31, 2014: RMB2.0 billion), investments (non-current) (December 31, 2013: RMB73 million, December 31, 2014: RMB1.6 billion) and accounts receivables (December 31, 2013: RMB1.1 billion, December 31, 2014: RMB1.4 billion). The inter-company receivables of RMB373 million and RMB RMB1.4 billion as of December 31, 2013 and 2014 mainly represented the cash paid by a VIE to one of the Company’s WFOEs for treasury cash management purpose.

As of December 31, 2013 and 2014, the VIEs’ liabilities mainly consisted of advance from customers (December 31, 2013: RMB2.1 billion , December 31, 2014: RMB3.5 billion), accounts payable (December 31, 2013: RMB1.3 billion, December 31, 2014: RMB1.8 billion), other payables and accruals (December 31, 2013: RMB181 million, December 31, 2014: RMB588 million), salary and welfare payable (December 31, 2013: RMB119 million, December 31, 2014: RMB195 million) and taxes payable (December 31, 2013: RMB46 million, December 31, 2014: RMB45 million). The inter-company payables as of December 31, 2013 and 2014 were RMB1.4 billion and RMB6.1 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.

	For the year ended December 31,
	2012	2013		2014
	RMB	RMB		RMB
Net revenues	2,465,286,325	3,137,211,893		4,138,380,618
Cost of revenues	644,886,101	904,328,902		1,252,538,920
Net income / (loss)	198,929,052	(74,463,933	)	(87,193,139	)

As aforementioned, the VIEs mainly conduct air-ticketing, travel agency, advertising and value-added telecommunication businesses. Revenues from VIEs accounted for around 56% of the Company’s total revenues in 2014. The air-ticketing and packaged-tour revenues continued to increase in 2014, primarily driven by the increase in the air-ticketing volume and leisure travel volume.

The VIEs’ net income before the deduction of the inter-company consulting fee charges were RMB1.1 billion, RMB1.3 billion and RMB1.1 billion for the years ended December 31, 2012, 2013 and 2014, respectively.

The amount of service fees paid by all the VIEs as a percentage of the VIEs’ total net income were 82.7%, 105.9%and 109.4% for the years ended December 31, 2012, 2013 and 2014, 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. The WFOEs did not request service fee payments of RMB286 million from Chengdu Ctrip and Chengdu Ctrip International during the years ended December 31 2012, primarily for tax planning purpose. In 2013, Chengdu Ctrip and Chengdu Ctrip International started to pay service fee to WFOEs, and the retained earnings of 2013 and 2014 have been transferred to the WFOEs, respectively. For remaining undistributed retained earnings, tax planning strategies are in place to support their enterprise income tax free treatment.

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$1.00 = RMB6.2046 on December 31, 2014, representing the certificated exchange rate published by the Federal Reserve Board. No representation is intended to imply that the RMB amounts could have been, or could be, converted, realized or settled into US$ at that rate on December 31, 2014, 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		20-30 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 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.

Investments

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

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. In October 2013, the Company contributed cash in return for 5% equity shares in Zhong An Online Property Insurance Co., Ltd. (“Zhong An Online”). In December 2013, the Company acquired approximately 4% equity shares in Keystone Lodging Holdings Limited (“Keystone”), which in 2013 merged with 7 Days Group Holdings Limited (“7 Days”), a leading economy hotel chain based in China. In 2014, dividends of RMB39 million are received from Keystone. Cost method of accounting was applied to both transactions due to lack of ability to exercise significant influence (Note 8). No new cost method investment transactions have occurred in 2014.

The Company applies equity method in accounting for our 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. In 2008, the Company acquired equity interest in Homeinns Hotel Group (“Homeinns” formerly Home Inns & Hotels Management Inc.) and on May 21, 2009, the Company started to have the ability to exercise significant influence and meeting requirement to apply equity method of accounting. In 2014, through a series of transactions, the Company culminated 35% share capital of Skyseas Holding International Ltd. (“Skyseas”) and provided a loan of US$80 million to Skyseas to finance its purchase of a cruise ship. The Company therefore has the ability to exercise significant influence on Skyseas and applied equity method to account for the investment (Note 8). 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 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. The Company has designated its investment in commons shares of China Lodging Group, Limited (“Hanting”), Tuniu Corporation (“Tuniu”) and eHi Car Services Limited(“eHi”) as available-for-sale equity securities, investment in shares with liquidation preference right of Tongcheng Network Technology Share Co., Ltd. (“LY.com”) and a travel agency focusing on teenager market as available-for-sale equity securities and its investments in convertible redeemable preferred shares (“Preferred Share”) of Easy Go Inc.(“Easy Go”), Dining Secretary China Limited (“Dining Secretary”) , Happy City Holdings Limited(“Happy City”) and a big-data advertisement company as available-for-sale debt securities in accordance with Accounting Standard Codification (“ASC”) 320-10, respectively (Note 8). Unrealized gains and losses on available-for-sale securities are excluded from earnings and reported as accumulated other comprehensive income (loss), net of tax. 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 instruments of the Group primarily comprise of cash and cash equivalents, restricted cash, short-term investments, accounts receivable, due from related parties, available-for-sale investments, accounts payable, due to related parties, advances from customers, short-term bank borrowings, other short-term liabilities and long-term debts. As of December 31, 2013 and 2014, carrying values of these financial instruments except for short-term investments and available-for-sale investments approximated their fair values because of their generally short maturities, and the carrying value of the long-term debts also approximates their fair value, as they bear interest at rates determined based on prevailing interest rates in the market. The Company reports short-term investments and 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 does not have any financial liabilities which must be measured at fair value on a recurring basis.

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. From January 1, 2009, the Group adopted ASC 805, “Business combinations”. Following this adoption, 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

Wing On Travel

In May 2010, to develop and expand our overseas business, our wholly-owned subsidiary C-Travel, a Cayman Island company, successfully completed the transaction to acquire 90% of the issued share capital of Wing On Travel’s travel service segment, a Hong Kong based travel service provider that offers packaged-tours as well as air tickets and hotel reservation services. We obtained control over Wing On Travel and have consolidated its financial statements since then. The total purchase price for the transaction is approximately RMB598 million (US$88 million). The cash payment is approximately RMB454 million (approximately US$68 million) after the Company assumed net current liability of Wing On Travel as of acquisition date. In February, 2012, Ctrip acquired the remaining 10% of the issued share capital of Wing On Travel’s travel service segment as operated through HKWOT (BVI) Limited, at a consideration of approximately RMB60 million (US$9.4 million). The purchase of the remaining 10% non-controlling interests was initiated by the Company is treated as an equity transaction. The difference between the book value of the 10% non-controlling interests and the cash consideration of Rmb21.7 million was recorded as additional paid in capital. Upon completion of this share purchase, Ctrip holds 100% of the share capital of Wing On Travel. Based on the Company’s assessment, financial results of Wing On Travel were not considered material to the Group for the years ended December 31, 2012, 2013 and 2014.

Travel agencies

The Company completed several transactions to acquire controlling shares of certain travel agencies 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.

In August, 2013, the Company completed the transaction to acquire controlling shares of a B2B hotel reservation company. The purchase consideration is approximately RMB47 million (US$8 million). The financial results of the acquired entity have been included in the Company’s consolidated financial statements since the acquisition date. In February, 2014, Ctrip acquired the remaining share capital of this B2B hotel reservation company at a consideration of approximately RMB44 million (US$7 million). The purchase of the remaining non-controlling interests initiated by the Company was treated as an equity transaction. The difference between the book value of the remaining non-controlling interests and the cash consideration was recorded as additional paid in capital. Upon completion of this share purchase, Ctrip holds 100% of the share capital of the B2B hotel reservation company.

In August, 2013, the Company completed the transaction to acquire 100% of the share capital of a wholesaler operated hotel reservation and air ticketing services. The purchase consideration is HK$125 million (US$16 million).

The results of the acquired entity’s operations have been included in the consolidated financial statements of the Company since the acquisition date. On the acquisition date, the 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 49% equity interest not held by the Company:

	RMB
Net assets	13,176,760

In October, 2014, the Company acquired the remaining 65% equity shares and obtained control with total purchase consideration of approximately RMB240 million which includes the cash consideration of RMB 115 million and the swapped non-controlling interest of one of the Company’s subsidiaries with the fair value of RMB 125 million. The Company also recognized a gain from the re-measurement of its previously held 35% equity interest to the fair value with amount of RMB100 million. As of December 31, 2014, the total unpaid cash consideration was RMB 97 million and will be paid in 2015. The financial results of the acquired company have been included in the Company’s consolidated financial statements since the date the Company obtained control and were not significant to the Company for the year ended December 31, 2014.

Other acquisitions

From time to time, the Company selectively acquired or invested in businesses that complement our existing business, and will continue to do so in the future. Other than disclosed above, none of such acquisitions or investments 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.

As of December 31, 2014, the step one analysis performed indicated that the fair value of the Company’s reporting units was substantially greater than the respective carrying value. There was no impairment of goodwill during the years ended December 31, 2012, 2013 and 2014. 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 patent and a cross-border travel agency license as of December 31, 2013 and 2014. 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, 2013 and 2014. 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 reviews intangible assets with indefinite lives annually for impairment.

No impairment on other intangible assets was recognized for the years ended December 31, 2012, 2013 and 2014.

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.

No impairment of long-lived assets was recognized for the years ended December 31, 2012, 2013, and 2014.

Accrued liability for customer reward program

The Group’s customers 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, 2013, and 2014, the Group’s accrued liability for its customer reward program amounted to RMB285 million and RMB431 million, respectively, based on the estimated liabilities under the customer reward program. Our expenses for the customer rewards program were approximately RMB157million, RMB203 million and RMB355 million for the years ended December 31, 2012, 2013 and 2014.

Deferred revenue

In 2011, the Group launched a coupon program, through which the Group provides coupons for customers who book selected hotels online through website. Customers who use the coupons receive credits in their virtual cash accounts upon check-out from the hotels and reviews for hotels submitted. Customers may redeem the amount of credits in their virtual cash account in cash, voucher, or mobile phone credit. In accordance with ASC 605-50 “Revenue Recognition: Customer Payments and Incentives”, the Group accounts for the estimated cost of future usage of coupons as contra-revenue or sales and marketing expenses in the consolidated statements.

Effective August 1, 2013, 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 hotel customers 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 customers 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

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 airline 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.

Allowance for doubtful accounts

Accounts receivable are recorded at the invoiced amount and do not bear interest. The Company reviews on a periodic basis for doubtful accounts for the outstanding trade receivable balances based on historical experience and information available. Additionally, we make specific bad debt provisions based on (i) our specific assessment of the collectability of all significant accounts; and (ii) any specific knowledge we have acquired that might indicate that an account is uncollectible. The facts and circumstances of each account may require us to use substantial judgment in assessing its collectability. The following table summarized the details of the Company’s allowance for doubtful accounts:

Cost of revenues

Cost of revenues consists primarily of payroll compensation of customer service center personnel, 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 RMB276 million, RMB538 million and RMB1.2 billion for the years ended December 31, 2012, 2013 and 2014 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

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, 2013 and 2014, 587,596 and 386,310 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. RSUs granted under 2007 Incentive Plan have a restricted period for 4 years. As of December 31, 2013 and 2014, 3,543,136 and 4,585,868 options and 623,424 and 1,058,608 RSUs were outstanding under the 2007 Incentive Plan.

Option modification

In January 2012, the compensation committee passed a resolution to replace all options that previously granted under the 2007 incentive plan but with exercise price above $120.00 per ordinary share, with maximum of 518,017 restricted share units (RSU) of the Company based on the conversion ratio at 4:1 (“the Replacement”). The total options modified approximate 1.9 million and the Company incurred no incremental cost for such modification.

A summary of option activity under the share option plans

The following table summarized the Company’s share option activity under all the option plans (in US$, except shares):

	Number of Shares		Weighted Average Exercise Price	Weighted Average Remaining Contractual Life (Years)	Aggregate Intrinsic Value

The Company’s current practice is to issue new shares to satisfy share option exercises.

The expected-to-vest options are the result of applying the pre-vesting forfeiture rate assumptions of 8% to total unvested options.

The aggregate intrinsic value in the table above represents the total intrinsic value (the aggregate difference between the Company’s closing stock price of US$182 as of December 31, 2014 and the exercise price for in-the-money options) that would have been received by the option holders if all in-the-money options had been exercised on December 31, 2014.

The total intrinsic value of options exercised during the years ended December 31, 2012, 2013 and 2014 were US$34million US$99 million and US$148 million, respectively.

The following table summarizes information related to outstanding and exercisable options as of December 31, 2014 (in US$, except shares):

	Outstanding			Exercisable

The weighted average fair value of options granted during the years ended December 31, 2012, 2013 and 2014 was US$38.01, US$38.40 and US$78.10 per share, respectively.

As of December 31, 2014, there was US$129 million of total unrecognized compensation cost, net of estimated forfeitures, related to unvested share options which are expected to be recognized over a weighted average period of 2.7 year. Total unrecognized compensation cost may be adjusted for future changes in estimated forfeitures. Total cash received from the exercise of share options amounted to RMB81,911,154, RMB180,261,090 and RMB184,579,173 for the year ended December 31, 2012, 2013 and 2014, respectively.

The Company calculated the estimated fair value of share options on the date of grant using the Black-Scholes pricing model with the following assumptions for the years ended December 31, 2012, 2013 and 2014:

	2012	2013	2014
Risk-free interest rate	0.71%-1.05%	0.69%-0.87%	1.66%-1.75%
Expected life (years)	5.0	5.0	5.0

A summary of RSUs activities under the share option plans

The Company granted 164,976, 259,365 and 761,514 RSUs to employees with 4 year requisite service period for the years ended December 31, 2012, 2013 and 2014, respectively. In additional, pursuant to the Replacement mentioned above, another 475,343 RSUs replaced the 1,901,372 options initially granted under the 2007 incentive plan.

The following table summarized the Company’s RSUs activities under all option plans (in US$, except shares):

	Number of Shares		Weighted average grant date fair value(US$)

* It does not include the impact of restricted shares converted from option.

Total share-based compensation cost for the RSUs amounted to US$12.5million, US$13.2 million and US$32.3 million for the years ended December 31, 2012, 2013 and 2014, respectively. As of December 31, 2014, there was US$129 million unrecognized compensation cost, net of estimated forfeitures, related to unvested restricted shares, which are to be recognized over a weighted average vesting period of 2.8 years. Total unrecognized compensation cost may be adjusted for future changes in estimated forfeitures.

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.

Effective January 1, 2007, the Company adopted 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.

As of both December 31, 2013 and 2014, the Company did not record any liability for uncertain tax positions. The Company’s policy is to recognize, if any, tax related interest as interest expenses and penalties as general and administrative expenses. For 2014 and 2013, the Company did not have any interest and penalties associated with tax positions.

Other income (net)

Other income primarily consists of financial subsidies, investment income and foreign exchange gains/(losses). Financial subsidies from local PRC government authority 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 authority. Financial subsidies are recognized as other income when received. Components of other income for the years ended December 31, 2012, 2013 and 2014 were as follows:

	2012		2013		2014
	RMB		RMB		RMB
Financial subsidies	90,280,139		119,697,248		132,094,928

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 can be stopped if such reserve has reached 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 Software Hotel Information, 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. During the years ended December 31, 2012, 2013, and 2014, appropriations to statutory reserves have been made of approximately RMB3.4 million, RMB13.5 million, and RMB15.6 million, respectively. The Company’s subsidiary in Taiwan, ezTravel, is required to allocate 10% of its after-tax profit to the statutory reserve in accordance with the Taiwan regulations. During the years ended December 31, 2012 and 2013, appropriations to statutory reserves equivalent to approximately RMB1.8 million and RMB 1.7 million have been made, respectively. There is no such regulation of providing statutory reserve in Hong Kong.

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 RMB1.9 billion as of December 31, 2014.

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, 2012, 2013 and 2014 were RMB3.6 billion, RMB4.6 billion and RMB5.0 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.

On June 13, 2012, the Company announced that the board of the Company has approved dividend distribution of US$300 million from its PRC subsidiaries to fund a new share repurchase program whereby Ctrip may purchase its own American depositary shares (“ADSs”). This dividend distribution was a one-time event out of the Company’s normal business course, and withholding tax is recorded only for such transaction accordingly. The PRC withholding tax amounted US$15 million was recorded in the Company’s 2012 financial results (Note 15).

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).

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.

Treasury stock consists of ADS repurchased by the Group under these three plans. In October 2013, US$45.5 million convertible senior notes issued in 2012 was early converted and 588,219 shares of repurchased treasury stock were delivered to bond holders. In 2014, US$61.6 million convertible senior notes issued in 2012 was converted and 846,131 shares of repurchased treasury stock were delivered to bond holders. As of December 31, 2014, the Company had 3,323,262 shares treasury stock at total cost of US$259 million. Treasury stock is accounted for under the cost method.

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 Statements.

The Company primarily generates its revenues from customers 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 March of 2013, the FASB issued ASU 2013-05, “Foreign Currency Matters (Topic 830), Parent’s Accounting for the Cumulative Translation Adjustment upon Derecognition of Certain Subsidiaries or Groups of Assets within a Foreign Entity or of an Investment in a Foreign Entity.” The amendments clarify the applicable guidance for the release of the cumulative translation adjustment when 1. an entity ceases to have a controlling financial interest in a subsidiary or group of assets that is a nonprofit activity or a business (other than a sale of in substance real estate or conveyance of oil and gas mineral rights) within a foreign entity; 2. there is a loss of a controlling financial interest in a foreign entity or a step acquisition involving an equity method investment that is a foreign entity; and 3. sales or transfers of a controlling financial interest within a foreign entity is the same irrespective of whether the sale or transfer is of a subsidiary or a group of assets (other than a sale of in substance real estate or conveyance of oil and gas mineral rights) that is a nonprofit activity or business. The amendments are effective prospectively for fiscal years (and interim reporting periods within those years) beginning after December 15, 2013. The Company adopted ASU 2013-05 effective January 1, 2014. Such adoption did not have a material effect on the Company’s financial position or results of operations.

In March of 2013, the FASB issued ASU 2013-11, “Income Taxes (Topic 740) Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists”. The amendment clarifies that an unrecognized tax benefit, or a portion of an unrecognized tax benefit, should be presented in the financial statements as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward, except as follows. To the extent a net operating loss carryforward, a similar tax loss, or a tax credit carryforward is not available at the reporting date under the tax law of the applicable jurisdiction to settle any additional income taxes that would result from the disallowance of a tax position or the tax law of the applicable jurisdiction does not require the entity to use, and the entity does not intend to use, the deferred tax asset for such purpose, the unrecognized tax benefit should be presented in the financial statements as a liability and should not be combined with deferred tax assets. The assessment of whether a deferred tax asset is available is based on the unrecognized tax benefit and deferred tax asset that exist at the reporting date and should be made presuming disallowance of the tax position at the reporting date. The amendments are effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. The Company adopted ASU 2013-11 effective January 1, 2014. Such adoption did not have a material effect on the Company’s financial position or results of operations.

In April 2014, the FASB issued ASU 2014-08, “Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity”. This update changed the threshold for reporting discontinued operations and added new disclosures for disposals. Under the updated guidance, a discontinued operation is defined as a component or group of components that is disposed of or is classified as held for sale and represents a strategic shift that has (or will have) a major effect on an entity’s operations and financial results. This ASU is effective prospectively for fiscal years, and interim periods within those years, beginning after December 15, 2014. This ASU is not reasonably expected in the future to have a material impact on the Company’s consolidated financial statements, because the Company does not have discontinued operations or disposals of components of an Entity.

In May 2014, the FASB and IASB issued their converged standard on revenue recognition. The objective of the revenue standard ASU 2014-09, “Revenue from Contracts with Customers (Topic 606)” is to provide a single, comprehensive revenue recognition model for all contracts with customers to improve comparability within industries, across industries, and across capital markets. The revenue standard contains principles that an entity will apply to determine the measurement of revenue and timing of when it is recognized. The underlying principle is that an entity will recognize revenue to depict the transfer of goods or services to customers at an amount that the entity expects to be entitled to in exchange for those goods or services. For public companies, the revenue standard is effective for the first interim period within annual reporting periods beginning after December 15, 2016 and early adoption is not permitted. The Company is in the process of evaluating the impact of the standard on its consolidated financial statements.

In February 2015, the FASB issued the ASU 2015-02, “Amendments to the Consolidation Analysis”. The objective of issuing the amendments in this Update is to change the analysis that a reporting entity must perform to determine whether it should consolidate certain types of legal entities. The amendments in this Update are an improvement to current US GAAP because they simplify the Codification and reduce the number of consolidation models through the elimination of the indefinite deferral of Statement 167 and because they place more emphasis on risk of loss when determining a controlling financial interest. The amendments in this Update are effective for public business entities for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2015. Early adoption is permitted, including adoption in an interim period. If an entity early adopts the amendments in an interim period, any adjustments should be reflected as of the beginning of the fiscal year that includes that interim period. A reporting entity may apply the amendments in this Update using a modified retrospective approach by recording a cumulative-effect adjustment to equity as of the beginning of the fiscal year of adoption. A reporting entity also may apply the amendments retrospectively. The Company is in the process of evaluating the impact of the 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, 2014, the Company held an aggregate equity interest of approximately 15.1% of the outstanding shares of Homeinns (or 14,400,765 shares). Given the level of investment and the common directors on Board of both companies, the Company applied equity method of accounting to account for the investment in Homeinns.

The Company calculated equity in income or losses of investment in Homeinns on one quarter lag basis, as allowed, as the financial statements of Homeinns were not available within a sufficient time period.

On October 1, 2011, Homeinns completed a transaction to acquire 100% equity interest in a business, pursuant to which Homeinns issued additional ordinary shares as part of the total consideration. As a result, the Company’s equity interest in Homeinns effectively decreased from 17.5% to 15.1%. In accordance with ASC 323-10-40-1, the Company accounts for a share issuance by an investee as if the investor had sold a proportionate share of its investment. The issuance price per share of the newly issued capital by the investee is higher than the Company’s average per share carrying amount, thus the Company recognized the non-cash gain of RMB39.3 million for the period ended December 31, 2012 as a result of the equity dilution impact. The Company picks up equity calculation of Homeinns on a quarter lag basis, as the Company is not able to timely obtain all necessary financial information from Homeinns to perform the equity investment reconciliations between the Company and Homeinns.

The carrying amount and unrealized securities holding profit for investment in Homeinns as of December 31, 2013 and 2014 were as follows:

(“RCL”) with amount of US$ 220 million. Thus the Company obtained the control over Skyseas and its financial results were consolidated with the Company’s consolidated financial statements on its incorporation.

In November 2014, the Company entered into a share transfer agreement with RCL to transfer 35% share capital of Skyseas to RCL for US$ 26.3 million, representing the Company’s original cost for the investment.

The Company has two out of five board seats of Skyseas and is entitled to appoint the senior management, including CEO. The Company lost the ability to control Skyseas after the share transfer. Therefore, the Company has applied equity method to account for the investment since December 2014 due to the Company continues to maintain the ability to exercise the significant influence. There was no gain or loss on the loss of control and deconsolidation though the Company deconsolidated cash of US$ 19 million in the transactions.

Pursuant to the CIT Law and Circular Caishui [2008]No.1 issued by Ministry of Finance of China on February 22, 2008, the dividends declared out of the profits earned after January 1, 2008 by a foreign invested enterprise(“FIE”) to its immediate holding company outside mainland China would be subject to withholding taxes. A favorable withholding tax rate will be applied if there is a tax treaty arrangement between Mainland China and the jurisdiction of the foreign holding company and other supplementary guidance/requirements stipulated by State Administration of Taxation (“SAT”) and tax treaty are met and proper procedures have been gone through. The Company’s subsidiaries, Ctrip Computer Technology, Ctrip Travel Information, Ctrip Travel Network, and Ctrip Information Technology are considered FIEs and are directly held by our subsidiaries in Hong Kong. According to double tax arrangement between Mainland and Hong Kong Special Administrative Region, dividends payable by an FIE in mainland China to the company in Hong Kong will be subject to 5% withholding tax, subject to approval of the tax authority. All of these foreign invested enterprises will be 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.

On June 13, 2012, the board of the Company has approved dividend distribution of US$300 million from its PRC subsidiaries to fund a new share repurchase program whereby Ctrip may purchase its own American depositary shares (“ADSs”). The dividends paid by the Company’s PRC subsidiaries to the Company through its Hong Kong subsidiary is subject to a 5% PRC withholding tax, of which RMB95 million (US$15 million) is accrued as of December 31, 2012.

The dividend distribution on June 13, 2012 aforesaid was a one-time event out of the Company’s normal business course, and withholding tax is recorded only for such transaction accordingly. The Company expects to indefinitely reinvest the remaining undistributed earnings generated after January 1, 2008 in the onshore PRC entities. As a result, no additional deferred tax liability was provided on the outside basis difference for the remaining undistributed earnings of RMB4.6 billion after January 1, 2008.

Income tax expense was RMB131 million (US$21 million) in the year ended December 31, 2014, decrease from RMB294 million in the year ended 2013. The effective income tax rate in year ended December 31, 2014 was 97%, as compared to 26% in the year ended 2013, mainly due to an increase in valuation allowance against certain deferred tax assets due to more tax losses generated from certain subsidiaries in 2014 that are not expected to be recovered.

As of December 31, 2013 and 2014, valuation allowance of RMB87 million and RMB183 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 December 31, 2014, the Group had net operating tax loss carry forwards amounted to RMB801 million which will expire from 2015 to 2018 if not used.

The provisions for income taxes for the years ended December 31, 2012, 2013 and 2014 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.

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 “Notes”) at par. The 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 Notes (which represents an initial conversion price of US$19.34 per ADS).

The net proceeds to the Company from the issuance of the Notes were US$175 million. The Company pays cash interest at an annual rate of 0.5% on the 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 Notes (September 15, 2015).

The 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 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 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 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 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 Notes. Settlement of the Purchased Call Option in ADSs, based on the number of ADSs issued upon conversion of the 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 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 December 31, 2014, the warrants had not been exercised and remained outstanding.

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 Notes, Purchased Call Option and the Issued Warrants (1) do not entail the same risks as the 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 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 Notes, Purchased Call Option and Issued Warrants transactions should be accounted for as separate transactions.

The Company has accounted for the Notes in accordance with ASC 470, as a single instrument as a long-term debt. The value of the Notes is measured by the cash received. As of December 31, 2014, RMB428 million (US$69 million) is reclassified as short-term debt to present the Notes may be redeemed within one year(Note 12).

The key terms of the Notes are as follows:

Redemption

Contingent redemption option

The Notes are not redeemable prior to the maturity date of September 15, 2017, except as described below. The holders of the Notes (the “Holders”) have a non-contingent option to require the Company to repurchase for cash all or any portion of their Notes on September 15, 2015. The repurchase price will equal 100% of the principal amount of the 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 Notes at a purchase price equal to 100% of the principal amount of the 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 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 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 Notes holder would recover all of their initial investment. Additionally, since the 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 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 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 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 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 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, in 2013, US$45.5 million of the notes was tendered, or 2.35 million ADS at the initial conversion rate of 51.7116 ADS per note. In 2014, US$61.6 million of the notes was tendered, or 3.4 million ADS at the initial conversion rate of 51.7116 ADS per note. 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 Notes due October 15, 2018 (the “Notes”) at par. The 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 Notes (which represents an initial conversion price of US$78.39 per ADS).

The net proceeds to the Company from the issuance of the Notes were US$780 million. The Company pays cash interest at an annual rate of 1.25% on the 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 Notes (October 15, 2018).

Concurrently with the issuance of the 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 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 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 Notes. Settlement of the Purchased Call Option in ADSs, based on the number of ADSs issued upon conversion of the 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 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, 2014, 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:

The Company has accounted for the Notes in accordance with ASC 470, as a single instrument as a long-term debt. The value of the Notes is measured by the cash received. As of December 31, 2014, RMB5.0 billion (US$800 million) is accounted as the value of the Notes in long-term debt.

The key terms of the Notes are as follows:

Redemption

Contingent redemption option

The Notes are not redeemable prior to the maturity date of October 15, 2018, except as described below. The holders of the Notes (the “Holders”) have a non-contingent option to require the Company to repurchase for cash all or any portion of their Notes on October 15, 2016. The repurchase price will equal 100% of the principal amount of the 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 Notes at a purchase price equal to 100% of the principal amount of the 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 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 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 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 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 Notes in connection with such make-whole fundamental change.

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 Notes as the set conversion price for the 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 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 deferred issuance costs and are amortized as interest expense, using the effective interest method, over the term of the Notes pursuant to ASC 835-30-35-2.

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 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 Priceline Convertible Notes

On August 7, 2014, the Company issued Convertible Senior Notes (the “Notes”) at an aggregate principal amount of US$500 million to the Priceline Group. The Notes are due on August 7, 2019 and bear interest of 1% annually which will be paid semi-annually beginning on August 7, 2014. The Notes will be convertible into the Company’s American Depositary Shares (“ADSs”) with an initial conversion price of approximately US$81.36 per ADS.

The Company has accounted for the Notes in accordance with ASC 470, as a single instrument within the consolidated financial statements. The value of the Notes is measured by the cash received. The Company recorded the interest expenses according to its annual interest rate.

In addition, the Company has granted the Priceline Group permission to acquire the Company’s shares in the open market over the next twelve months, so that combined with the shares convertible under the bond, the Priceline Group may hold up to 10% of the Company’s outstanding shares. As the potential purchase will be conducted by the market price, there is no accounting implication.

Accelerated share repurchase arrangement

On September 26, 2012, the Company entered into a Capped Call Option Transaction Agreement (the “Agreement”) for an initial notion amount of US$75 million with JP Morgan Chase Bank, National Association. The transaction enables the Company to execute a treasury stock repurchase up to 4.4 million ADSs upon maturity on December 19, 2012. The Agreement consists of two components, a treasure stock repurchase prepayment of US$62,182,346 (purchased call option) with a strike price of US$0.0001 per ADS, plus a warrant (a written call option) with an upper strike price of US$14.3621 per ADS. The total strike notion amount for the Capped Call Option Transaction is US$63,749,958.

Upon maturity:

If the ADS trading price is above upper strike price (US$14.3621 per ADS), Ctrip retains a premium of US$1,567,612 and the initial cash prepayment of US$62,182,346 in cash or a number of ADSs that is calculated by dividing the cash settlement amount of US$63,749,958 by the maturity date’s trading price per ADS;

If the ADS trading price is below upper strike price (US$14.3621 per ADS), Ctrip receives a fixed number of 4,438,763 ADSs.

The Capped Call Option Transaction meet the criteria for being indexed to the Company’s own stock and is therefore be excluded from the scope of ASC 815. The initial cash payment is recorded within shareholders’ equity as a component of additional paid in capital.

On December 19, 2012, the Capped Call Option Transaction expired with cash settlement. The difference between cash settlement and cash prepayment has been accounted for as an equity transaction with the amount recorded in additional paid in capital. As the ADS trading price is above the upper strike price, the Company selected cash settlement of the Capped Call Option amounting to US$63.7 million.

In October 2013, US$45.5 million convertible senior notes issued in 2012 were early converted and 588,219 shares of repurchased treasury stock were delivered to the notes holders. As of December 31, 2013, the Company had 3,777,087 shares treasury stock at total cost of US$256 million.

In 2014, US$61.6 million convertible senior notes issued in 2012 were early converted and 846,131 shares of repurchased treasury stock were delivered to the notes holders. As of December 31, 2014, the Company had 3,323,262 shares treasury stock at total cost of US$259 million.

Capital commitments

As of December 31, 2014, the Company had outstanding capital commitments totaling RMB70 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 December 31, 2014, the amount under these guarantee arrangements was approximately RMB884 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. Therefore, we have not recorded any liability beyond what is required in connection with 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.
