(a)

Guangzhou School and Guangzhou Panyu School were newly established in the year ended May 31, 2014. Although they are separate legal entities, from perspective of the Group’s internal management, they together with Guangzhou Haizhu School are considered as one school since they are operated by the same local management in Guangzhou.

(b)	Although Fuyang School is a separate legal entity, from perspective of the Group’s internal management, Fuyang School and Hangzhou School are considered as one school since they are operated by the same local management in Hangzhou.

The VIE arrangements

PRC laws and regulations currently require any foreign entity that invests in the education business in China to be an educational institution with relevant experience in providing educational services outside China. The Company’s offshore holding companies are not educational institutions and do not provide educational services outside China. In addition, in the PRC, foreign ownership of high schools for students in grades ten to twelve is restricted and foreign ownership of primary and middle schools for students in grades one to nine is prohibited. Accordingly, the Company’s offshore holding companies are not allowed to directly own and operate schools in China. The Company conducts substantially all of its education business in China through contractual arrangements with its VIE, New Oriental China and its schools and subsidiaries. Since the operations of New Oriental China and the schools are closely interrelated and almost indistinguishable from one another, the risks and rewards associated with their operations are substantially the same. In addition, the Company consolidates New Oriental China, its schools and subsidiaries as disclosed. Therefore, the Company aggregates the disclosures related to New Oriental China and New Oriental China’s schools and subsidiaries as variable interest entities and referred to them as “the VIE” in the Company’s consolidated financial statements. The VIE holds the requisite licenses and permits necessary to conduct the Company’s education business. In addition, the VIE holds leases and other assets necessary to operate the Company’s schools and learning centers, employs teachers and generates substantially all of the Company’s revenues. The Company and its wholly owned subsidiaries in China (the “WFOEs”) have entered into the following contractual arrangements with New Oriental China, New Oriental China’s schools and subsidiaries and New Oriental China’s shareholders that enable the Company to (1) have power to direct the activities that most significantly affects the economic performance of the VIE, and (2) receive the economic benefits of the VIE that could be significant to the VIE. Accordingly, the Company is considered the primary beneficiary of the VIE and has consolidated the VIE’s financial results of operations, assets and liabilities in the Company’s consolidated financial statements. In making the conclusion that the Company is the primary beneficiary of the VIE, the Company believes the Company’s rights under the terms of the exclusive option agreement provide it with a substantive kick out right. More specifically, the Company believes the terms of the exclusive option agreement are valid, binding and enforceable under PRC laws and regulations currently in effect. The Company also believes that the minimum amount of consideration permitted by the applicable PRC law to exercise the option does not represent a financial barrier or disincentive for the Company to currently exercise its rights under the exclusive option agreement. A simple majority vote of the Company’s board of directors is required to pass a resolution to exercise the Company’s rights under the exclusive option agreement, for which Mr. Michael Minhong Yu (“Mr. Yu”)’s consent is not required. The Company’s rights under the exclusive option agreement give the Company the power to control the shareholder of New Oriental China and thus the power to direct the activities that most significantly impact the schools’ economic performance given that New Oriental China has the power to direct the activities of the schools via its sponsorship interest. In addition, the Company’s rights under the power of attorney also reinforce the Company’s abilities to direct the activities that most significantly impact the VIE’s economic performance. The Company also believes that this ability to exercise control ensures that the VIE will continue to execute and renew service agreements and pay service fees to the Company. By charging service fees in whatever amounts the Company deems fit, and by ensuring that service agreements are executed and renewed indefinitely, the Company has the rights to receive substantially all of the economic benefits from the VIE.

The VIE arrangements - continued

Service agreements. There are four types of service agreements: (i) trademark license agreements, (ii) new enrollment system development service agreements, (iii) other operating service agreements, and (iv) sale of educational software agreements.

(i) Trademark license agreements. Pursuant to the trademark license agreement dated May 13, 2006 between the Company as the licensor and New Oriental China as the licensee, the Company has licensed the trademarks to New Oriental China for its use in China. The Company has also allowed New Oriental China to enter into sub-license agreements with its schools and subsidiaries pursuant to which each of the schools and subsidiaries may use the trademarks in China by paying license fees. This license is valid from May 14, 2006 to December 31, 2050, subject to the renewal every ten years upon the expiration of the trademark registration. Pursuant to the second trademark license agreement dated December 20, 2010 entered into between Shanghai Smart Words as the licensor and a subsidiary of New Oriental China as the licensee, Shanghai Smart Words has granted a license to a subsidiary of New Oriental China to use certain trademarks for a license fee equal to 5% of the licensee’s monthly revenues. The term of this license is two years and is automatically renewed unless otherwise terminated by Shanghai Smart Words.

(ii) New enrollment system development service agreements. Beijing Decision has entered into new enrollment system development service agreements with the schools of New Oriental China, under which Beijing Decision agreed to provide new enrollment system development and regular maintenance services to those schools of New Oriental China for a fee equal to the applicable fee rate multiplied by the number of new student enrollments. These agreements can be renewed by both parties to the agreements.

(iii) Other operating service agreements. Pursuant to operating service agreements between certain WFOEs and the schools or the subsidiaries of New Oriental China, the WFOEs have agreed to provide certain operating services to the schools or the subsidiaries of New Oriental China for fees that are calculated based on a percentage, ranging from 1.0% to 6.0%, of respective revenues of each of the schools and subsidiaries. A majority of these agreements provide unlimited two-year or five-year automatic renewal without consent of the WFOEs. The remaining agreements can be renewed by both parties to the agreements.

(iv) Sale of educational software agreements. Seven WFOEs, namely Beijing Hewstone, Beijing Pioneer, Beijing Smart Wood, Shanghai Smart Words, Beijing Joy Tend, Beijing Magnificence and Beijing Top, entered into agreements whereby the WFOEs sells various self-developed educational software to the schools or subsidiaries of New Oriental China. Except for four agreements that are silent on renewal, these agreements provide unlimited two-year automatic renewal terms, and schools and subsidiaries of New Oriental China cannot terminate the agreements without the consent of the WFOEs in China.

The VIE arrangements - continued

Equity pledge agreement. Pursuant to the equity pledge agreements dated May 25, 2006 among New Oriental China, all of the shareholders of New Oriental China, Beijing Hewstone and Beijing Decision, each shareholder of New Oriental China agreed to pledge his or its equity interest in New Oriental China to Beijing Hewstone and Beijing Decision to secure the performance of the VIE’s obligations under the existing service agreements and any such agreements to be entered into in the future. The shareholders of New Oriental China agreed not to transfer, sell, pledge, dispose of or otherwise create any encumbrance on their equity interests in New Oriental China without the prior written consent of Beijing Decision and Beijing Hewstone.

In January 2012, ten former shareholders of New Oriental China completed the transfer, for no consideration, of all of their equity interests in New Oriental China to Century Friendship, a PRC domestic enterprise controlled by the Company’s founder, chairman and chief executive officer, Mr. Yu. Prior to the transfer, Century Friendship had held 53% of the equity interests in the New Oriental China while the ten former shareholders of New Oriental China held the remaining equity interests. In connection to the transfer, five new equity pledge agreements dated April 23, 2012 were entered into among New Oriental China, Century Friendship and five WFOEs, whereby Century Friendship has agreed to pledge all of its equity interests in New Oriental China to the WFOEs to secure the VIE’s performance of their obligations under the trademark license agreements, new enrollment system development service agreements, other operating service agreements and sale of educational software agreements. Century Friendship has agreed not to transfer, sell, pledge, dispose of or otherwise create any encumbrance on its equity interests in New Oriental China without the prior written consents of the WFOEs. The terms of the April 2012 equity pledge agreements are substantially the same as the 2006 agreements.

Exclusive option agreement. Pursuant to the exclusive option agreements entered into on various dates, as amended on May 25, 2006, among the Company, New Oriental China and its shareholders, the shareholders of New Oriental China are obligated to sell to the Company, and the Company have an exclusive, irrevocable and unconditional right to purchase, or cause the shareholders of New Oriental China to sell to the Company’s designated party, in the Company’s sole discretion, part or all of the shareholders’ equity interests in New Oriental China when and to the extent that applicable PRC law permits the Company to own part or all of such equity interests in New Oriental China. In addition, pursuant to the exclusive option agreements, the Company has an exclusive, irrevocable and unconditional right to request any existing shareholder of New Oriental China to transfer all or part of the equity interest in New Oriental China held by such shareholder to another PRC person or entity designated by the Company at any time in the discretion. The price to be paid by the Company or a PRC person or entity designated by the WFOEs will be the minimum amount of consideration permitted by applicable PRC law at the time when such share transfer occurs. As a result of the ten former shareholders of New Oriental China transferring all of their equity interests in New Oriental China to Century Friendship in January 2012, Century Friendship executed a new option agreement with Shanghai Smart Words and New Oriental China on April 23, 2012. The terms of this new option agreement are substantially the same as the 2006 agreements.

The VIE arrangements - continued

Power of Attorney. On December 3, 2012, Century Friendship, in the capacity of the sole shareholder of New Oriental China, executed a proxy agreement and power of attorney with Beijing Pioneer, which is one of the Company’s wholly owned subsidiaries in China, and New Oriental China, whereby Century Friendship irrevocably appoints and constitutes Beijing Pioneer as its attorney-in-fact to exercise on Century Friendship’s behalf any and all rights that Century Friendship has in respect of its equity interests in New Oriental China. This proxy agreement and power of attorney became effective on December 3, 2012 and replaces the powers of attorney executed by Century Friendship on April 23, 2012. The proxy agreement and power of attorney will remain effective as long as New Oriental China exists. Century Friendship does not have the right to terminate the proxy agreement and power of attorney or revoke the appointment of the attorney-in-fact without the prior written consent of Beijing Pioneer.

Risks in relation to the VIE structure

The Company believes that the contractual arrangements with New Oriental China and its current shareholder are in compliance with PRC laws and regulations and are legally enforceable. However, uncertainties in the PRC legal system could limit the Company’s ability to enforce the contractual arrangements. If the legal structure and contractual arrangements were found to be in violation of PRC laws and regulations, the PRC government could:

•

revoke the business and operating licenses of the Company’s PRC subsidiaries, New Oriental China and its schools and subsidiaries;

•

discontinue or restrict the operations of any related-party transactions among the Company’s PRC subsidiaries, New Oriental China and its schools and subsidiaries;

•

limit the Group’s business expansion in China by way of entering into contractual arrangements;

•

impose fines or other requirements with which the Company’s PRC subsidiaries, New Oriental China and its schools and subsidiaries may not be able to comply;

•

require the Company or the Company’s PRC subsidiaries, New Oriental China and its schools and subsidiaries to restructure the relevant ownership structure or operations; or

•

restrict or prohibit the Company’s use of the proceeds of the additional public offering to finance the Group’s business and operations in China.

The Company’s ability to conduct its education business may be negatively affected if the PRC government were to carry out of any of the aforementioned actions. As a result, the Company may not be able to consolidate New Oriental China and its schools and subsidiaries in its consolidated financial statements as it may lose the ability to exert effective control over New Oriental China and its schools and subsidiaries and its shareholder, and it may lose the ability to receive economic benefits from New Oriental China and its schools and subsidiaries. The Company, however, does not believe such actions would result in the liquidation or dissolution of the Company, the WFOEs or New Oriental China or its schools or subsidiaries.

The VIE arrangements - continued

Risks in relation to the VIE structure - continued

Mr. Yu is the controlling shareholder of Century Friendship, which owns all of the equity interests in New Oriental China and Mr. Yu is also a beneficial owner of the Company. The interests of Mr. Yu as the beneficial owner of New Oriental China may differ from the interests of the Company as a whole, since Mr. Yu is only one of the beneficial shareholders of the company, holding 16.57% of the total common shares outstanding as of May 31, 2014. The Company cannot assure that when conflicts of interest arise, Mr. Yu will act in the best interests of the Company or that conflicts of interests will be resolved in the Company’s favor. Currently, the Company does not have existing arrangements to address potential conflicts of interest Mr. Yu may encounter in his capacity as a beneficial owner and director of New Oriental China, on the one hand, and as a beneficial owner and director of the Company, on the other hand. The Company believes Mr. Yu will not act contrary to any of the contractual arrangements and the exclusive option agreement provides the Company with a mechanism to remove Mr. Yu as a beneficial shareholder of New Oriental China should he act to the detriment of the Company. The Company relies on Mr. Yu, as a director and executive officer of the Company, to fulfill his fiduciary duties and abide by laws of the PRC and Cayman Islands and act in the best interest of the Company. If the Company cannot resolve any conflicts of interest or disputes between the Company and Mr. Yu, the Company would have to rely on legal proceedings, which could result in disruption of its business, and there is substantial uncertainty as to the outcome of any such legal proceedings.

In addition, the current sole shareholder of the New Oriental China is also a beneficial owner of the Company and therefore has no current interest in seeking to act contrary to the contractual arrangements. However, to further protect the investors’ interest from any risk that the shareholders of the New Oriental China may act contrary to the contractual arrangements, the Company, through Beijing Pioneer, entered into an irrevocable power of attorney with Century Friendship on December 3, 2012, which replaces the powers of attorney executed by Century Friendship on April 23, 2012. Through the power of attorney, Century Friendship entrusted Beijing Pioneer as its proxy to exercise its rights as the shareholder of New Oriental China with respect to an aggregate of 100% of the equity interests in New Oriental China.

The Company’s operations not conducted through contractual arrangements with the VIE primarily consist of its kindergarten programs and the leasing of its commercial property. As of the fiscal years ended May 31, 2013 and 2014, the VIE accounted for an aggregate of 65.5% and 65.3%, respectively, of the consolidated total assets, and 94.4% and 95.3%, respectively, of the consolidated total liabilities. The assets were not associated with the VIE primarily consist of cash and cash equivalents, prepaid expenses, short-term investments and long-term investments.

The VIE arrangements - continued

Risks in relation to the VIE structure - continued

There are no consolidated VIE’s assets that are collateral for the VIE’s obligations and can only be used to settle the VIE’s obligations. There are no creditors (or beneficial interest holders) of the VIE that have recourse to the general credit of the Company or any of its consolidated subsidiaries. There are no terms in any arrangements, considering both explicit arrangements and implicit variable interests, that require the Company or its subsidiaries to provide financial support to the VIE. However, if the VIE ever needs financial support, the Company or its subsidiaries may, at its option and subject to statutory limits and restrictions, provide financial support to its VIE through loans to the shareholder of the VIE or entrustment loans to the VIE.

Relevant PRC laws and regulations restrict the VIE from transferring a portion of its net assets, equivalent to the balance of its statutory reserve and its share capital, to the Company in the form of loans and advances or cash dividends. Please refer to Note 23 for disclosure of restricted net assets.

Significant Accounting Policies

2.	SIGNIFICANT ACCOUNTING POLICIES

Basis of presentation

The consolidated financial statements of the Group have been prepared in accordance with the accounting principles generally accepted in the United States of America (“US GAAP”).

Basis of consolidation

The consolidated financial statements include the financial statements of the Company, its subsidiaries, its VIE and VIE’s subsidiaries and schools. The Company and its WFOEs have entered into contractual arrangements with the VIE and its shareholder, which enable the Company to (1) have power to direct activities that most significantly affect the economic performance of the VIE, and (2) receive the economic benefits of the VIE that could be significant to the VIE. Accordingly, the Company is considered the primary beneficiary of the VIE and has consolidated the VIE’s financial results of operations, assets and liabilities in the Company’s consolidated financial statements. All inter-company transactions and balances have been eliminated upon consolidation.

Use of estimates

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 and revenue and expenses in the financial statements and accompanying notes. Significant accounting estimates reflected in the Group’s consolidated financial statements include purchase price allocation relating to the business acquired, the valuation allowance for deferred tax assets, allowance for doubtful accounts, economic lives and impairment of property and equipment, impairment of goodwill and indefinite-lived intangible assets, and share-based compensation. Actual results could differ from those estimates.

Business combinations

Business combinations are recorded using the acquisition method of accounting. The purchase price of the acquisition is allocated to the tangible assets, liabilities, identifiable intangible assets acquired and non-controlling interest, if any, based on their estimated fair values as of the acquisition date. The excess of the purchase price over those fair values is recorded as goodwill. Acquisition-related expenses and restructuring costs are expensed as incurred.

Where the consideration in an acquisition includes contingent consideration and the payment of which depends on the achievement of certain specified conditions post-acquisition, the contingent consideration is recognized and measured at its fair value at the acquisition date and if recorded as a liability, it is subsequently carried at fair value with changes in fair value reflected in earnings.

Cash and cash equivalents

Cash and cash equivalents consist of cash on hand and highly liquid investments which are unrestricted as to withdrawal or use, and which have original maturities of three months or less when purchased.

Term deposits

Term deposits consist of deposits placed with financial institutions with original maturities of greater than three months and less than one year.

Short-term investments

Short term investments consist of held-to-maturity investments with the maturity of less than one year. The Group’s short-term held-to-maturity investments are classified as short-term investments on the consolidated balance sheets based on their contractual maturity dates which are less than one year and are stated at their amortized costs.

The Group reviews its held-to-maturity investments for other-than-temporary impairment (“OTTI”) based on the specific identification method. The Group considers available quantitative and qualitative evidence in evaluating the potential impairment of its short-term investments. If the cost of an investment exceeds the investment’s fair value, the Group considers, among other factors, general market conditions, expected future performance of the investees, the duration and the extent to which the fair value of the investment is less than the cost, and the Group’s intent and ability to hold the investments. OTTI is recognized as a loss in the income statement.

Restricted cash

Restricted cash represents Renminbi (“RMB”) deposits in bank accounts as deposits for establishing new schools and subsidiaries.

Allowance for doubtful accounts

Accounts receivable represents amounts due from corporate customers of the Group’s various schools and subsidiaries. The Group provides allowance for doubtful accounts equal to the estimated amounts. The Group’s estimates are based on historical collection experience and a review of the current status of accounts receivable and advances to suppliers. Accounts receivable and advances to suppliers are presented net of allowance for doubtful accounts.

Changes in the allowance for doubtful accounts were as follows:


	As of May 31,
	2013			2014
	US$			US$
Beginning balance		48			182
Charge during the year		192			254
Written-off		(58	)		(171	)

Ending balance		182			265

Inventory

Inventory is stated at the lower of cost or market value.

Land use rights

Land use rights are recorded at cost and amortized on a straight-line basis over the remaining term of the land certificate, from 38.5 to 50 years.

Property and equipment

Property and equipment is stated at cost less accumulated depreciation and amortization. Depreciation and amortization is calculated on a straight line basis over the following estimated economic lives:


Buildings		20-50 years
Transportation equipment		10 years
Furniture and education equipment		5 years
Computer equipment and software		3 years
Leasehold improvements		Shorter of the lease term or estimated economic life

Construction in progress

The Group constructs certain of its property and equipment. In addition to cost under the construction contracts, interest cost and external costs directly related to the construction of such facilities, including equipment installation and shipping costs, are capitalized. Depreciation is recorded at the time assets are ready for the intended use.

Impairment of long-lived assets

The Group reviews its long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may no longer be recoverable. When these events occur, the Group measures impairment by comparing the carrying value of the long-lived assets to the estimated undiscounted future cash flows expected to result from the use of the assets and their eventual disposition. If the sum of the expected undiscounted cash flow is less than the carrying amount of the assets, the Group would recognize an impairment loss based on the fair value of the assets. The Group did not record impairment losses on long-lived assets during the years ended May 31, 2012, 2013 and 2014.

Goodwill

Goodwill represents the excess of the purchase price over the fair value of identifiable net assets acquired in business combinations. Goodwill is not amortized but is tested for impairment annually or more frequently if events or changes in circumstances indicate that it might be impaired.

Goodwill is tested for impairment at the reporting unit level on an annual basis (May 31 for the Group) and between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying value. These events or circumstances could include a significant change in the stock prices, business climate, legal factors, operating performance indicators, competition, or sale or disposition of a significant portion of a reporting unit.

Application of the goodwill impairment test requires judgment, including the identification of reporting units, assignment of assets and liabilities to reporting units, assignment of goodwill to reporting units, and determination of the fair value of each reporting unit. The estimation of fair value of each reporting unit using a discounted cash flow methodology also requires significant judgments, including estimation of future cash flows, which is dependent on internal forecasts, estimation of the long-term rate of growth for the Group’s business, estimation of the useful life over which cash flows will occur, and determination of the Group’s weighted average cost of capital. The estimates used to calculate the fair value of a reporting unit change from year to year based on operating results and market conditions. Changes in these estimates and assumptions could materially affect the determination of fair value and goodwill impairment for the reporting unit.

In September 2011, the FASB issued an authoritative pronouncement related to testing goodwill for impairment. The guidance permits the Group to first assess qualitative factors to determine whether it is “more likely than not” that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step goodwill impairment test. The Group adopted this pronouncement since June 2012. If it is more likely than not that the fair value of a reporting unit is less than its carrying amount, goodwill is then tested following a two-step process. The first step compares the fair value of each reporting unit to its carrying amount, including goodwill. If the fair value of each reporting unit exceeds its carrying amount, goodwill is not considered to be impaired and the second step will not be required. If the carrying amount of a reporting unit exceeds its fair value, the second step compares the implied fair value of goodwill to the carrying value of a reporting unit’s goodwill.

The implied fair value of goodwill is determined in a manner similar to accounting for a business combination with the allocation of the assessed fair value determined in the first step to the assets and liabilities of the reporting unit. The excess of the fair value of the reporting unit over the amounts assigned to the assets and liabilities is the implied fair value of goodwill.

An impairment loss is recognized for any excess in the carrying value of goodwill over the implied fair value of goodwill. The Group recognized no impairment loss on goodwill for any of the periods presented.

Impairment of indefinite-lived intangible assets

An intangible asset that is not subject to amortization is tested for impairment at least annually or more frequently if events or changes in circumstances indicate that the asset might be impaired. Such impairment test is to compare the fair values of assets with their carrying value amounts and an impairment loss is recognized if and when the carrying amounts exceed the fair values. The estimates of fair values of intangible assets not subject to amortization are determined using various discounted cash flow valuation methodologies. Significant assumptions are inherent in this process, including estimates of discount rates or market price. Discount rate assumptions are based on an assessment of the risk inherent in the respective intangible assets. Market prices are based on potential purchase quote from third party, if any. The Group recognized no impairment loss on indefinite-lived intangible assets for any of the periods presented.

Acquired intangible assets with definite lives

Acquired intangible assets with definite lives consist of trademark, license and course wares, and are carried at cost less accumulated amortization and impairment. Amortization of acquired intangible assets is calculated on a straight-line basis over the shorter of the contractual terms or the expected economic lives of the acquired assets. The weighted average amortization periods by major intangible assets class are as follows:


Trademark			10 years
License			20 years
Student base			1.75 year

Cost Method Investments

For investee companies over which the Group does not have significant influence and a controlling interest, the Group carries the investment at cost and recognize as income for any dividend received from distribution of the investee’s earnings.

The Group reviews its cost method investments for impairment whenever an event or circumstance indicates that an OTTI has occurred. The Group considers available quantitative and qualitative evidence in evaluating potential impairment of its cost method investments. An impairment charge is recorded if the cost of an investment exceeds its fair value and such excess is determined to be other-than temporary.

The Group estimated the fair value of these investee companies based on discounted cash flow approach. Factors the Group considers in making such a determination include general market conditions, the duration and the extent to which the fair value of an investment is less than its cost, and the Group’s intent and ability to hold such investment. The Group did not record impairment losses on its cost method investments during the years ended May 31, 2012, 2013 and 2014.

Equity Method Investment

Investee company over which the Group has the ability to exercise significant influence, but does not have a controlling interest, are accounted for using the equity method. Significant influence is generally considered to exist when the Group has an ownership interest in the voting stock of the investee between 20% and 50%, and other factors, such as representation on the investee’s board of directors, voting rights and the impact of commercial arrangements, are considered in determining whether the equity method of accounting is appropriate. In addition, as disclosed in Note 13(c), the Group accounts for its 65% equity interests in Beijing MaxEn International Education Consulting Co., Ltd (“MaxEn”) as equity method investment since the other investor has significant participating rights and the Group does not have controlling interests.

An impairment charge is recorded if the carrying amount of the investment exceeds its fair value and this condition is determined to be other-than temporary. The Group estimated the fair value of the investee company based on comparable quoted price for similar investment in active market, if applicable, or discounted cash flow approach which requires significant judgments, including the estimation of future cash flows, which is dependent on internal forecasts, the estimation of long term growth rate of a company’s business, the estimation of the useful life over which cash flows will occur, and the determination of the weighted average cost of capital. The Company did not record impairment losses on its equity method investment during the years ended May 31, 2012, 2013 and 2014.

Available-for-sale securities Investments

Investment classified as available-for-sale are carried at their fair values and the unrealized gains or losses from the changes in fair values are included in accumulated other comprehensive income.

The Group reviews its investments for OTTI based on the specific identification method. The Group considers available quantitative and qualitative evidence in evaluating potential impairment of its investments. If the cost of an investment exceeds the investment’s fair value, the Group considers, among other factors, general market conditions, government economic plans, the duration and the extent to which the fair value of the investment is less than the cost, the Group’s intent and ability to hold the investment, and the financial condition and near term prospects of the issuers.

Long-term held-to-maturity investment

The Group’s long-term held-to-maturity investment represents a trust guaranteed by a bank with the maturity of more than one year, which is stated at its amortized cost.

Revenue recognition

Revenue is recognized when persuasive evidence that an arrangement exists, delivery of the product or service has occurred, the selling price is both fixed and determinable and collection is reasonably assured. Revenue is reported net of business taxes and refunds. Business tax amounted to US$26,692, US$33,859 and US$39,909 for the years ended May 31, 2012, 2013 and 2014, respectively. The primary sources of the Group’s revenues are as follows:

(a)

Educational programs and services

The educational programs and services consist of language training and test preparation courses, primary and secondary school education and college admission examination retaking training services. Tuition is generally paid in advance and is initially recorded as deferred revenue. Tuition revenue for educational programs and services is recognized proportionately as the instructions are delivered, and is reported net of business taxes and related surcharges, and tuition refunds. Students are entitled to a short term course trial period which commences on the date the course begins. Tuition refunds are provided to students if they decide within the trial period that they no longer want to take the course. Tuition refunds have been insignificant in the fiscal years ended May 31, 2012, 2013 and 2014. After the trial period, if a student withdraws from a class, usually no refunds will be provided and any collected but unearned portion of the fee is recognized at that time.

The Group also sells online-learning cards primarily to distributors at fixed price after deducting a pre-determined fixed discount to the face value of the cards. Online-learning card sales represent prepaid service fees received from students for e-learning services. The prepaid service fee is recorded as deferred revenue upon receiving the upfront payment. Revenue is recognized upon actual usage of the cards by the students based on the number of minutes the students use the e-learning services, of which the actual usage is tracked by the Group on an individual basis. Upon the expiration of the online-learning card, which ranges from six months to one year from the date of sale of the card to the distributor, the Group will recognize the remaining unused minutes as revenue.

(b)

Books and others

The Group sells educational books or other educational materials either through its own book stores or websites or through third party distributors. Revenue from sales made through the Group’s book stores is recognized upon sales to customers. Revenue through distributors is recognized once the products are sold to the end customers.

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 are charged to the consolidated statements of operations on a straight-line basis over the shorter of the lease term or estimated economic life.

Advertising costs

The Group expenses advertising costs as they incurred. Total advertising expenses were US$28,960, US$29,725 and US$41,952 for the years ended May 31, 2012, 2013 and 2014, respectively, and have been included as part of selling and marketing expenses.

Government subsidies

The Group recognizes government subsidies as miscellaneous income when they are received because they are not subject to any past or future conditions, there are no performance conditions or conditions of use, and are not subject to future return. Government subsidies received and recognized as miscellaneous income totaled US$971, US$1,196 and US$1,437 for the years ended May 31, 2012, 2013 and 2014, respectively.

Foreign currency translation

The Company’s functional and reporting currency is the United States dollars (“U.S. dollars”). The financial records of the Company’s subsidiaries, New Oriental China and its schools and subsidiaries located in the PRC are maintained in its local currency, RMB which is the functional currency of these entities. The financial records of the Company’s subsidiaries located in Hong Kong are maintained in U.S. dollars, which is the functional currency of these entities. The functional currency of the Company’s subsidiaries in Hong Kong is the U.S. dollars.

Monetary assets and liabilities denominated in currencies other than the applicable functional currencies are translated into the reporting currency at the rates of exchange ruling at the balance sheet date. Equity accounts are translated at historical exchange rates, and revenues and expenses are translated using the average rate of exchange in effect during the reporting period. Translation adjustments are reported and shown as a separate component of other comprehensive income in the consolidated statements of changes in equity and comprehensive income.

Transactions in currencies other than the functional currencies during the year are converted into the applicable functional currencies at the applicable rates of exchange prevailing at the dates of the transactions. Exchange gains and losses are recognized in the consolidated statements of operations.

Foreign currency risk

The RMB is not a freely convertible currency. The State Administration for Foreign Exchange, under the authority of the People’s Bank of China, controls the conversion of RMB into other currencies. The value of the RMB is subject to changes in central government policies and to international economic and political developments affecting supply and demand in the China Foreign Exchange Trading System market. The Group’s cash and cash equivalents, restricted cash, and term deposits denominated in RMB amounted to US$415,897 and US$451,676 at May 31, 2013 and 2014, respectively.

Fair value

Fair value is the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities required or permitted to be recorded at fair value, the Group considers the principal or most advantageous market in which it would transact, and it considers assumptions that market participants would use when valuing the asset or liability. Authoritative literature provides a fair value hierarchy which prioritizes the inputs to valuation techniques used to measure fair value into three broad levels. The level in the hierarchy within which the fair value measurement in its entirety falls is based upon the lowest level of input that is significant to the fair value measurement as follows:

Level 1

Level 1 applies to assets or liabilities for which there are quoted prices in active markets for identical assets or liabilities.

Level 2

Level 2 applies to assets or liabilities for which there are inputs other than quoted prices included within Level 1 that are observable for the asset or liability such as quoted prices for similar assets or liabilities in active markets; quoted prices for identical assets or liabilities in markets with insufficient volume or infrequent transactions (less active markets); or model-derived valuations in which significant inputs are observable or can be derived principally from, or corroborated by, observable market data.

Level 3

Level 3 applies to assets or liabilities for which there are unobservable inputs to the valuation methodology that are significant to the measurement of the fair value of the assets or liabilities.

Measured fair value on a recurring basis

The Group measured its financial assets and liabilities including cash equivalents at fair value on a recurring basis as of May 31, 2013 and 2014. Cash equivalents are classified within Level 1 of the fair value hierarchy because they are valued based on the quoted market price in an active market.

The Group did not have Level 3 investments as of May 31, 2013 and 2014.

As of May 31, 2013 and 2014, respectively, the available-for sale securities included in the long-term investment is measured and recorded at fair value on a recurring basis in periods subsequent to their initial recognition was as follows:

The Company measured the fair value of the investment in Alo7.com based on the purchase price of preferred shares paid by third paritis with similar terms incurred in the financing activity (Level 2) close to the fiscal year end of 2014.

The Company measured the fair value of the investment in Tarena based on Level 1 inputs, which is the quoted stock price in the active market.

Measured fair value on a nonrecurring basis

Long-term investments other than Alo7.com Ltd. and Tarena, goodwill and other intangible assets are measured at fair value on a nonrecurring basis when impairment is recognized.

The Group measured long term investments other than Alo7.com Ltd. and Tarena, goodwill at fair value on a nonrecurring basis when it is annually evaluated or whenever events or changes in circumstances indicate that carrying amount of a reporting unit exceeds its fair value as a result of the impairment assessments, and the Group measured acquired intangible assets using income approach - discounted cash flow method when events or changes in circumstances indicate that the carrying amount of an asset may no longer be recoverable. The Group did not recognize any impairment loss related to investments, goodwill and acquired intangible assets for the years ended May 31, 2012, 2013 and 2014. The fair value was determined using models with significant unobservable inputs (Level 3 inputs), primarily the management projection of discounted future cash flow and the discount rate.

Fair value of financial instruments

The Group’s financial instruments consist primarily of cash and cash equivalents, term deposits, restricted cash, short-term held-to-maturity investments, accounts receivable, amount due from/to related parties, available-for-sale securities investments, long-term held-to-maturity investment and accounts payable. The carrying amounts of cash and cash equivalents, term deposits, restricted cash, short-term held-to-maturity investments, accounts receivable, amount due from/to related parties, and accounts payable approximate their fair values due to the short-term maturities of these instruments. Long-term held-to-maturity investment is stated at its amortized cost.

Net income per share

Basic net income per share is computed by dividing income attributable to holders of common shares by the weighted average number of common shares outstanding during the year. Diluted net income per common share reflects the potential dilution that could occur if securities or other contracts to issue common shares were exercised into common shares. Common share equivalents are excluded from the computation of the diluted net income per share in years when their effect would be anti-dilutive.

Income taxes

The Group accounts for income taxes using the asset and liability approach. Under this method, deferred tax assets and liabilities are determined based on the difference between the financial reporting and tax bases of assets and liabilities using enacted tax rates that will be in effect for the period in which the differences are expected to reverse. The effect on deferred taxes of a change in tax rates is recognized in the consolidated statements of operations in the period of change. Deferred tax assets are reduced by a valuation allowance when it is considered more likely than not that some portion or all of the deferred tax assets will not be realized.

The Group accounts for uncertain tax positions by reporting a liability for unrecognized tax benefits resulting from uncertain tax positions taken or expected to be taken in a tax return. Tax benefits are recognized from uncertain tax positions when the Group believes that it is more likely than not that the tax position will be sustained on examination by the taxing authorities based on the technical merits of the position. The Group recognizes interest and penalties, if any, related to unrecognized tax benefits in income tax expense.

Comprehensive income

Comprehensive income includes net income, unrealized gain or loss on available-for-sale securities and foreign currency translation adjustments. Comprehensive income is reported in the consolidated statements of comprehensive income.

Share-based compensation

Share-based payments to employees and directors are measured based on the grant-date fair value of the equity instrument issued and recognized as compensation expense net of a forfeiture rate on a straight-line basis over the requisite service period, with a corresponding addition to paid-in capital. The Group uses the binomial option pricing model to measure the fair value of options granted and the quoted market price of the Company’s equity shares to measure the fair value of NES granted to employees at each measurement date. The binomial option pricing model is adopted because the Group believes that considering the possibility of exercise of an option over the life of the option, as affected by the reality of changing stock prices and non-constant risk free rates, would better reflect the measurement objective of relevant accounting literature.

The amount of compensation expense recognized at any date is at least equal to the portion of the fair value of the awards that are vested as of that date. The estimate of forfeitures is based on historical turnover rate and will be adjusted over the requisite service period to the extent that actual forfeitures differ, or are expected to differ from such estimates. Changes in estimated forfeitures will be recognized through a cumulative catch-up adjustment in the period of change and will impact the amount of share-based compensation expense to be recognized in future periods.

Concentration of credit risk

Financial instruments that potentially subject the Company to significant concentration of credit risk consist primarily of cash and cash equivalents, term deposits, restricted cash, and accounts receivable. As of May 31, 2014, substantially all of the Group’s cash and cash equivalents, and term deposits were deposited with financial institutions with high-credit ratings and quality. Accounts receivable are typically unsecured and are derived from revenues earned from customers in PRC. The Group performs periodic credit evaluations and provides an allowance for doubtful accounts to reduce the accounts receivable balance to its net realizable value. The Group did not have any customers constituting 10% or more of the consolidated net revenues and accounts receivable in fiscal years 2012, 2013 and 2014.

Newly adopted accounting pronouncements

In December 2011, the FASB issued an authoritative pronouncement related to disclosures about offsetting assets and liabilities. The guidance requires an entity to disclose information about offsetting and related arrangements to enable users of its financial statements to understand the effect of those arrangements on its financial position. In January 2013, the FASB further clarifies that ordinary trade receivables and receivables are not in the scope of the authoritative pronouncement and the pronouncement applies only to derivatives, repurchase agreements and reverse purchase agreements, and securities borrowing and securities lending transactions that are either offset in accordance with specific criteria contained in the FASB Accounting Standards Codification (Codification) or subject to a master netting arrangement or similar agreement. An entity is required to apply the amendments for annual reporting periods beginning on or after January 1, 2013, and interim periods within those annual periods. An entity should provide the disclosures required by those amendments retrospectively for all comparative periods presented. The adoption of this guidance did not have a significant effect on its consolidated financial statements.

In February 2013, the FASB issued an authoritative pronouncement related to reporting of amounts reclassified out of accumulated other comprehensive income, to improve the transparency of reporting these reclassifications. Other comprehensive income includes gains and losses that are initially excluded from net income for an accounting period. Those gains and losses are later reclassified out of accumulated other comprehensive income into net income. The amendments in this Accounting Standards Updates (“ASU”) do not change the current requirements for reporting net income or other comprehensive income in financial statements. All of the information that this ASU requires already is required to be disclosed elsewhere in the financial statements under US GAAP.

The new amendments will require an organization to:

•

Present (either on the face of the statement where net income is presented or in the notes) the effects on the line items of net income of significant amounts reclassified out of accumulated other comprehensive income - but only if the item reclassified is required under US GAAP to be reclassified to net income in its entirety in the same reporting period.

•

Cross-reference to other disclosures currently required under US GAAP for other reclassification items (that are not required under US GAAP) to be reclassified directly to net income in their entirety in the same reporting period. This would be the case when a portion of the amount reclassified out of accumulated other comprehensive income is initially transferred to a balance sheet account (e.g., inventory for pension-related amounts) instead of directly to income or expense

The amendments apply to all public and private companies that report items of other comprehensive income. Public companies are required to comply with these amendments for all reporting periods (interim and annual). The amendments are effective for reporting periods beginning after December 15, 2012, for public companies. Early adoption is permitted. The adoption of this guidance did not have a significant effect on its consolidated financial statements.

In July 2013, the FASB issued a pronouncement which provides guidance on financial statement presentation of an unrecognized tax benefits when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. The FASB’s objective in issuing this ASU is to eliminate diversity in practice resulting from a lack of guidance on this topic in current U.S. GAAP.

The amendments in this ASU state 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.

This ASU applies to all entities that have unrecognized tax benefits when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists at the reporting date. The amendments in this ASU are effective for fiscal years, and interim periods within those years, beginning after December 15, 2013. Early adoption is permitted. The amendments should be applied prospectively to all unrecognized tax benefits that exist at the effective date. Retrospective application is permitted. The adoption of this guidance did not have a significant effect on its consolidated financial statements.

Recently issued accounting pronouncements not yet adopted

In January, 2014, the FASB issued a pronouncement which provides guidance on the accounting for service concession arrangements. This ASU specifies that an operating entity should not account for a service concession arrangement, within the scope of this ASU, as a lease in accordance with Topic 840, Leases. Service concession arrangements may become more prevalent in the United States as public-sector entities seek alternative ways to provide public services on a more efficient and cost-effective basis.

An operating entity should refer to other Codification Topics as applicable to account for various aspects of a service concession arrangement. The amendments also specify that the infrastructure used in a service concession arrangement should not be recognized as property, plant, and equipment of the operating entity.

The amendments in this ASU should be applied on a modified retrospective basis to service concession arrangements that exist at the beginning of an entity’s fiscal year of adoption. The modified retrospective approach requires the cumulative effect of applying this ASU to arrangements existing at the beginning of the period of adoption to be recognized as an adjustment to the opening retained earnings balance for the annual period of adoption. The amendments are effective for a public business entity for annual periods, and interim periods within those annual periods, beginning after December 15, 2014. The Group does not expect the adoption of this guidance will have a significant effect on its consolidated financial statements.

On April 10, 2014, the FASB issued Accounting Standard Update 2014-08, which amends the definition of a discontinued operation in ASC 205-20 and requires entities to provide additional disclosures about discontinued operations as well as disposal transactions that do not meet the discontinued-operations criteria. The new guidance eliminates the second and third criteria of discontinued operation in ASC 205-20-45-1 and instead requires discontinued-operations treatment for disposals of a component or group of components that represents a strategic shift that has or will have a major impact on an entity’s operations or financial results. The ASU also expands the scope of ASC 205-20 to disposals of equity method investments and businesses that, upon initial acquisition, qualify as held for sale.

The ASU also requires entities to reclassify assets and liabilities of a discontinued operation for all comparative periods presented in the statement of financial position.

Regarding the statement of cash flows, an entity must disclose, in all periods presented, either (1) operating and investing cash flows or (2) depreciation and amortization, capital expenditures, and significant operating and investing noncash items related to the discontinued operation.

The ASU is effective prospectively for all disposals (except disposals classified as held for sale before the adoption date) or components initially classified as held for sale in periods beginning on or after December 15, 2014. Early adoption is permitted. The Group does not expect the adoption of this guidance will have a significant effect on its consolidated financial statements.

In May 2014, the FASB issued, ASU 2014-09,“Revenue from Contracts with Customers (Topic 606)”. The guidance substantially converges final standards on revenue recognition between the FASB and the International Accounting Standards Board providing a framework on addressing revenue recognition issues and, upon its effective date, replaces almost all exiting revenue recognition guidance, including industry-specific guidance, in current U.S. generally accepted accounting principles.

The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. To achieve that core principle, an entity should apply the following steps:

•

Step 1: Identify the contract(s) with a customer.

•

Step 2: Identify the performance obligations in the contract.

•

Step 3: Determine the transaction price.

•

Step 4: Allocate the transaction price to the performance obligations in the contract.

•

Step 5: Recognize revenue when (or as) the entity satisfies a performance obligation.

For a public entity, the amendments in this ASU are effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. Early application is not permitted. The Group is in the process of evaluating the impact of adoption of this guidance on the Group’s consolidated financial statements.

In June 2014, the FASB issued a new pronouncement which requires that a performance target that affects vesting and that could be achieved after the requisite service period be treated as a performance condition. A reporting entity should apply existing guidance in Topic 718, Compensation—Stock Compensation, as it relates to awards with performance conditions that affect vesting to account for such awards. The performance target should not be reflected in estimating the grant-date fair value of the award. Compensation cost should be recognized in the period in which it becomes probable that the performance target will be achieved and should represent the compensation cost attributable to the period(s) for which the requisite service has already been rendered. If the performance target becomes probable of being achieved before the end of the requisite service period, the remaining unrecognized compensation cost should be recognized prospectively over the remaining requisite service period. The total amount of compensation cost recognized during and after the requisite service period should reflect the number of awards that are expected to vest and should be adjusted to reflect those awards that ultimately vest. The requisite service period ends when the employee can cease rendering service and still be eligible to vest in the award if the performance target is achieved.

The amendments in this ASU are effective for annual periods and interim periods within those annual periods beginning after December 15, 2015. Earlier adoption is permitted. The Group does not expect the adoption of this guidance will have a significant effect on the Group’s consolidated financial statements.

Short-term investments consist of various fixed-income financial products purchased from Chinese banks and trusts and are classified as held-to-maturity investments as the Group has the positive intent and ability to hold the investments to maturity. The maturities of these financial products range from one month to less than one year, with interest rates ranging from 2.3% to 8.4%.

(a)

In December 2006, the Group acquired 20% interest in Talent Boom. The Group has no representation on Talent Boom’s board of directors or its management and does not have the ability to exercise significant influence over the operating and financial policies of Talent Boom. Accordingly, the investment in Talent Boom was accounted for as a cost-method investment.

(b)

In September 2011, the Group signed a share subscription agreement to invest US$2,000 for 5% equity ownership interest in Dajie.com. The fair value of Dajie.com’s equity ownership interest is not readily determinable and the Group does not have the ability to exercise significant influence over the operating and financial policies of Dajie.com. Accordingly, the investment in Dajie.com has been accounted for as a cost-method investment.

(c)

In September 2012, New Oriental China and McGraw-Hill Hong Kong Limited set up a Joint Venture, MaxEn. New Oriental China invested US$6,500 cash and US$2,780 self-developed technologies with the book value of zero for its 65% equity interest. The Group does not have a controlling power over MaxEn because the other investor, McGraw-Hill Hong Kong Limited, has significant participating rights. The Group has the ability to exercise significant influence over the operating and financing activities of MaxEn. Therefore, the investment has been accounted for as an equity method investment. In 2014, the Group disposed 100% equity interest in Boost Caring and North Star to MaxEn for a total cash consideration of US$1,924 (Note 4). The Group recognized its share of the changes in net assets of MaxEn accordingly.

On March 5, 2012, the Company acquired a convertible promissory from Alo7.com for $1,000, which entitled the Company to automatic convert the note into identical equity securities issued at subsequent financing on or before July 1, 2012. If conversion term not triggered, Alo7 would repay the amount on December 31, 2013. On July 1, 2012, the Company converted the $1,000 promissory note into convertible redeemable preferred shares and warrants issued by Alo7.com, for 3.4% equity ownership interest in Alo7.com on an as-converted basis.

In March 2014, the Company further invested $2,576 into Alo7.com, for preferred shares, which was equivalent to 5.9% equity ownership interests on an as-converted basis. This investment is classified as available-for-sale securities and measured subsequently at fair value which is considered as Level 2 inputs. The Company measured the fair value of the investment in Alo7.com based on the purchase price of preferred shares paid by third parties with similar terms incurred in the financing activity close to the fiscal year end of 2014. Unrealized holding gains of nil, nil and US$631 were reported in other comprehensive income for the years ended May 31, 2012, 2013 and 2014, respectively.

The above equity interests were diluted by Alo7.com’s subsequent financing activities. As of May 31, 2014, the Company had 8.8% equity interests in Alo7.com on an as-converted basis.

(e)

In March 2014, the Company invested US$13,500 in Tarena, which is a service provider of IT professional education in China, for 2.96% ownership. This investment is classified as available-for-sale securities and measured subsequently at fair value which is considered as Level 1 inputs. Unrealized holding loss of US$45 was reported in other comprehensive income for the year ended May 31, 2014.

(f)

The Group’s long-term held-to-maturity investment consists of trust guaranteed by a bank with the maturity more than one year, which is stated at its amortized cost. The trust was invested in April 2014 and interest income of $1,404 was recognized in the consolidated statements of operations for the year ended May 31, 2014.

SHARE-BASED COMPENSATION

On January 20, 2006, the Company adopted 2006 Share Incentive Plan, under which the Company may grant share options to purchase up to 8,000,000 common shares of the Group, to its employees, directors and consultants. The number of common shares available for grant under the 2006 Share Incentive Plan may be increased annually by (i) an additional 5,000,000 shares on January 1, 2007, (ii) an additional 5,000,000 shares on January 1, 2008, and (iii) an annual increase in common shares to be added on the first business day of each calendar year beginning in 2009 equal to the lesser of (x) 3,000,000 shares, (y) two percent (2%) of total common shares outstanding as of such date, or (z) a lesser number of shares as determined by the Group’s management. In the event the aggregate number of shares that may be issued in any given year under all share compensation plans has reached the maximum number of shares allowed in that year, the Company may grant additional awards up to 2,000,000 shares, or extra shares. The number of shares granted in excess of the annual maximum in any given year will result in the reduction of the maximum shares available for grant in the next year.

As of May 31, 2014, the Company has transferred 16,000,000 common shares to its depositary bank to be issued to employees and non-employees upon the exercise of their vested share options or upon the vesting of non-vested equity shares (“NES”). During the years ended May 31, 2013 and 2014, the Company has repurchased 1,683,400 and 762,100 common shares, respectively, from the open market and the shares are reserved for the employees and non-employees to exercise of their vested share options and NES in future. As of May 31, 2014, 620,721 treasury shares remain for future issuance upon the exercise of share options and vesting of NES.

The Company recorded total share-based compensation of US$24,125, US$ 27,242 and US$20,079 during the years ended May 31, 2012, 2013 and 2014, respectively.

Share options

The following table summarizes information regarding the share options granted:


Share options	Shares granted		Grant-date fair value		Exercise price
			US$		US$
Grant date:
February 28, 2006		7,099,500		1.00		2.02
July 21, 2006		1,620,000		1.15		2.38
September 7, 2006		100,000		2.38		3.75
March 5, 2007		3,946,500		4.09		8.75
January 17, 2012		3,060,000		10.33		12.19

Total		15,826,000

The exercise price of share options is at least 100% of the fair value of the common shares on the date of the grant. The term of a share option is up to ten years from the date of grant. The share options generally vest over three years at six-month vesting increments per year.

As of May 31, 2014, 11,285,510 common shares out of the 16,000,000 common shares had been issued to employees and non-employees upon the exercise of their share options, and 1,014,727 shares out of the 2,445,500 treasury shares had been reissued to employees and non-employees upon exercise of their share options.

A summary of share options activity under 2006 Share Incentive Plan for years ended May 31, 2012, 2013 and 2014 was as follows:


	Number of options			Weighted average exercise prices		Weighted average remaining contractual life		Aggregated intrinsic value

Options exercisable at May 31, 2014		810,155			9.03		5.40		13,601

The total intrinsic value of share options exercised during the years ended May 31, 2012, 2013 and 2014 were US$4,121, US$7,486 and US$34,578, respectively. The weighted average grant date fair value of share options granted during the year ended May 31, 2012, 2013 and 2014 was US$10.33, nil and nil, respectively. As of May 31, 2014, total unrecognized compensation expense relating to unvested share options of US$4,336 is expected to be recognized over a weighted average period of 0.63 years.

The fair value of share options granted on January 17, 2012 was estimated on the date of grant using the binomial option pricing model with the following assumptions:


Risk-free interest rate of return	1.83	%
Volatility	56	%
Dividend yield	0	%
Fair value of the underlying ordinary shares	US$10.33
Exercise price	US$12.19
Exercisable date	1/6 of options vests semi-annually through December 31, 2014
Expiry date	January 17, 2017
Life of option (years)	5
Exercise multiple	2.8
Turnover rate	5.57	%
Number of nodes	200

(a)

Volatility

The volatility of the underlying ordinary shares during the life of the share options was estimated based on the Company’s historical stock price volatility over a period commensurate to the expected term of the share options.

(b)

Risk-free interest rate

Risk-free interest rate was estimated based on the yield to maturity of US$ denominated China international government bonds with a maturity period commensurate with the contractual life of the share options.

(c)

Dividend yield

The dividend yield was estimated based on the Company’s expected dividend distributions during a period commensurate with the contractual life of the share options.

(d)

Exercise price

The exercise price of the share options was determined by the Company’s board of directors, which is generally quoted market price of the Company’s ordinary shares on the date of grant.

(e)

Fair value of underlying ordinary shares

The fair value of the ordinary shares underlying the share options is the quoted market price of the Company’s ordinary shares on the date of grant.

(f)

Life of option

The life of the share option is based on the stated contractual life of the share options.

(g)

Number of nodes

This number divides the life to expiration into a number of equal time slots. It determines the number of level in the binomial tree.

(h)

Exercise multiple

A ratio of the stock price to the contractual strike price at which point it is assumed that the share option will be exercised prior to expiration

(i)

Forfeiture rate

The Company’s estimate based on historical employee turnover.

The Company is incorporated in the Cayman Islands. Under the current laws of the Cayman Islands, the Company is not subject to income or capital gains taxes. In addition, dividend payments are not subject to withholdings tax in the Cayman Islands.

The Company’s subsidiaries Smart Shine, Winner Park and Elite Concept are located in Hong Kong and are subject to an income tax rate of 16.5% for taxable income earned in Hong Kong. These subsidiaries recorded income tax expense of US$11, US$10 and US$4,399 during the years ended May 31, 2012, 2013 and 2014, respectively. On October 7, 2013, the Company paid a cash dividend of US$54,476 to shareholders, of which US$39,585 and US$14,891 were funded by retained earnings and additional paid in capital. The withholding tax of US$4,399 in connection with the dividend was fully paid during the year ended May 31, 2014.

The Company’s PRC subsidiaries, New Oriental China and its schools and subsidiaries are subject to the 25% standard enterprise income tax except for those accepted as deemed profit method enterprises, or qualified for small-scale enterprises, or granted preferential tax treatment.

Enterprises that qualify as a high and new technology enterprise (“HNTE”) are subject to a tax rate of 15%. Beijing Decision, Beijing Hewstone and Xuncheng continued to qualify as HNTE in Beijing and were subject to a tax rate of 15% during the years ended May 31, 2012 and 2013. For the year ended May 31, 2014, these companies are in the process of renewing the HNTE certification and could continue to apply to the 15% tax rate as long as they sustain the HNTE status. The income taxes of Beijing Decision, Beijing Hewstone and Xucheng were calculated at the rate of 15%, as the management has performed self-assessment and believed the companies have fully met the criteria required for HNTE.

Enterprises that qualify as the “newly established software enterprise” (“NESE”) are exempt from EIT for two years beginning the enterprise’s first profitable year followed by a tax rate of 12.5% for the succeeding three years. Beijing Pioneer, Shanghai Smart Words, Beijing Smart Wood, Beijing Right Time and Beijing Joy Tend were qualified as NESE and were exempt from income taxes from January 2010 through December 31, 2011, from January 2011 through December 31, 2012, from January 2012 through December 31, 2013, from January 2013 through December 31, 2014 and from January 2013 through December 31, 2014, respectively, and a tax rate of 12.5% through December 31, 2014, through December 31, 2015, through December 31, 2016, through December 31, 2017 and through December 31, 2017, respectively. Beijing Top and Beijing Magnificence were qualified as NESE and will be exempt from income taxes for two years beginning in their first profitable year followed by a tax rate of 12.5% for the succeeding three years.

Beijing Haidian School was not required by the governing tax bureau to pay any EIT since its establishment through May 31, 2014. If Beijing Haidian School is required to pay EIT in future, this could have material impact to the Group’s consolidated financial statements. However, the Group believes that it is more likely than not that any change to the tax treatment of Beijing Haidian School shall be prospectively applied.

Significant components of the Group’s deferred tax assets and liabilities were as follows:


	As of May 31,
	2013			2014
	US$			US$
Current deferred tax assets
Allowance doubtful accounts		73			83
Accrued expenses		9,249			12,353

Non-current deferred tax liabilities
Acquired of non-current assets		(1,836	)		(1,722	)

Total non-current deferred tax liabilities		(1,836	)		(1,722	)

The Group does not file combined or consolidated tax returns, therefore, losses from individual subsidiaries or the VIE may not be used to offset other subsidiaries’ earnings within the Group.

The Group determined the valuation allowance on an entity by entity basis. The valuation allowance, which is primarily related to entities with net operating loss carry-forwards for which the Company does not believe it will ultimately be realized, was US$4,274 as of May 31, 2014, or a decrease of US$228 from US$4,502 as of May 31, 2013.

As of the year ended May 31, 2014, the Group had net operating loss carried forward of US$25,787 from New Oriental China and its schools and subsidiaries, which will expire on various dates from May 31, 2015 to May 31, 2019.

A reconciliation of the effective tax rates from the 25% statutory tax rates was as follows for the years ended May 31, 2012, 2013 and 2014:


	Years ended May 31,
	2012			2013			2014
	%			%			%
Statutory tax rate		25.00			25.00			25.00
Effect of expenses not deductible for tax purposes		3.58			8.70			4.33
Effect of differential tax rate other than tax holiday		0.11			(1.58	)		(0.00	)
Effect of tax holiday		(23.99	)		(21.18	)		(20.34	)

Effect of dividend withholding tax		—			—			1.81

Total provision for income taxes		7.51			10.01			10.71

If the tax holidays granted to WFOEs and current tax treatments on certain schools and subsidiaries of New Oriental China were not available, the Group’s income tax expense would have increased by US$34,416, US$32,489 and US$49,464, the basic net income per share attributable to the Company would decrease by US$0.22, US$0.21 and US$0.32 for the years ended May 31, 2012, 2013 and 2014, respectively, and the diluted net income per share attributable to the Company would decrease by US$0.22 and, US$0.21 and US$0.31 for the years ended May 31, 2012, 2013 and 2014, respectively.

Under the New Income Tax Law effective from January 1, 2008, the rules for determining whether an entity is resident in the PRC for tax purposes have changed and the determination of residence depends among other things on the “place of actual management”. If the Group, or its non-PRC subsidiaries, were to be determined as a PRC resident for tax purposes, they would be subject to a 25% income tax rate on its worldwide income including the income arising in jurisdictions outside the PRC. The Group does not believe that its legal entities organized outside of the PRC are considered PRC residents.

If the Company were to be a non-resident for PRC tax purposes, dividends paid to it out of profits earned after January 1, 2008 would be subject to a withholding tax. In the case of dividends paid by PRC schools and subsidiaries to their foreign investors, the withholding tax would be 10%, unless any such foreign investor’s jurisdiction of incorporation has a tax treaty with China that provides for a different withholding arrangement. During the year ended May 31, 2014, Hewstone paid US$4,399 withholding tax when it paid a special dividend to its parent company, Elite Concept.

Aggregate undistributed earnings of the Company’s PRC subsidiaries and VIE that are available for distribution was US$602,377 and US$788,016 as of May 31, 2013 and May 31, 2014, respectively. Upon distribution of such earnings, the Company will be subject to PRC EIT taxes, the amount of which is impractical to estimate. The Company did not record any tax on any of the aforementioned undistributed earnings because the relevant subsidiaries and VIE does not intend to declare dividends and the Company intends to permanently reinvest it within the PRC. Additionally, no deferred tax liability was recorded for taxable temporary differences attributable to the undistributed earnings because the Company believes the undistributed earnings can be distributed in a manner that would not be subject to income tax.

The Group did not identify any significant unrecognized tax benefits for the years ended May 31, 2012, 2013 and 2014. The Group did not incur any significant interest and penalties related to potential underpaid income tax expenses and also does not anticipate any significant increases or decreases in unrecognized tax benefits in the next twelve months. The Group has no material unrecognized tax benefits which would favorably affect the effective income tax rate in future periods.

According to the PRC Tax Administration and Collection Law, the tax authority may require the taxpayer or the withholding agent to make delinquent tax payment within three years if the underpayment of taxes is resulted from the tax authority’s act or error. No late payment surcharge will be assessed under such circumstances. The statute of limitation will be three years if the underpayment of taxes is due to the computational errors made by the taxpayer or the withholding agent. Late payment surcharge will be assessed in such case. The statute of limitation will be extended to five years under special circumstances which are not clearly defined (but an underpayment of tax liability exceeding US$16 (RMB0.1 million) is specifically listed as a “special circumstance”). The statute of limitation for transfer pricing related issue is ten years. There is no statute of limitation in the case of tax evasion. Therefore, the Group’s PRC domiciled entities are subject to examination by the PRC tax authorities based on the above.

Since April 2010, the Group began renting a large portion of a building owned by Metropolis Holding China Limited for office space. In March 2012, Metropolis Holding China Limited was acquired by a company wholly owned by Mr.Yu, the Group’s chairman and chief executive officer. As a result, Metropolis Holding China Limited became a related party of the Group thereafter. As of May 31, 2014, the non-current and current amounts due from Metropolis Holding China Limited were US$930 and US$1,073 respectively, which represented prepaid rent and deposit for the building. The amount of the rental payments was determined based on the prevailing market rates and was duly approved by all of the directors.

The six operating segments are identified as language training and test preparation, primary and secondary school education, on-line education, content development and distribution, post-secondary education and overseas study consulting services. Language training and test preparation and primary and secondary education have been identified as reportable segments. Online education, content development and distribution, post-secondary education and overseas study consulting services operating segments were aggregated as others because individually they do not exceed the 10% quantitative threshold.

Statutory Reserve

STATUTORY RESERVE

Prior to payment of dividends, pursuant to the laws applicable to the PRC’s Foreign Investment Enterprises, the Company’s subsidiaries and VIEs in the PRC must make appropriations from after-tax profit to non-distributable reserve funds as determined by the Board of Directors of each company. These reserves include (i) general reserve and (ii) the development fund.

Subject to certain cumulative limits, the general reserve requires annual appropriations of 10% of after-tax profits as determined under PRC laws and regulations at each year-end until the balance reaches 50% of the PRC entity registered capital; the other reserve appropriations are at the Company’s discretion. These reserves can only be used for specific purposes of enterprise expansion and are not distributable as cash dividends. During the year ended May 31, 2012, $2,453 was deducted from the general reserve to adjust for excess appropriations made in prior periods. During the years ended May 31, 2013 and 2014, US$524 and US$1,029 was accrued for the general reserve, respectively.

PRC laws and regulations require private schools that require reasonable returns to make annual appropriations of 25% of after-tax income prior to payments of dividend to its development fund, which is to be used for the construction or maintenance of the school or procurement or upgrading of educational equipment, while in the case of a private school that does not require reasonable return, this amount should be equivalent to no less than 25% of the annual increase of net assets of the school as determined in accordance with generally accepted accounting principles in the PRC. During the years ended May 31, 2012, 2013 and 2014, appropriations to the development fund amounted to US$71,602, US$21,946, and US$21,116, respectively.

The Company did not make appropriations to the development fund reserves for the years ended May 31, 2010, 2011 or any periods prior to that; however, in the year ended May 31, 2012, all of the under-reserved amounts for all prior periods’ development fund, together with the amount that shall have been appropriated for fiscal year 2012, have been appropriated. During the year ended May 31, 2012, appropriations to the development fund amounted to $71,602, for which $57,377 was attributed to periods prior to fiscal year 2012.

These reserves are included as statutory reserves in the consolidated statements of changes in equity and comprehensive income. The Group allocated US$69,149, US$22,470 and US$22,145 to statutory reserves during the years ended May 31, 2012, 2013 and 2014, respectively. The statutory reserves cannot be transferred to the Company in the form of loans or advances and are not distributable as cash dividends except in the event of liquidation.

RESTRICTED NET ASSETS

Relevant PRC laws and regulations restrict the WFOEs and VIE from transferring a portion of their net assets, equivalent to the balance of their statutory reserves and their share capital, to the Company in the form of loans, advances or cash dividends.

The WFOEs’ accumulated profits may be distributed as dividends to the Company without the consent of a third party. The VIE’s revenues and accumulated profits may be transferred to the Company through contractual arrangements without the consent of a third party. Under applicable PRC law, loans from PRC companies to their offshore affiliated entities require governmental approval, and advances by PRC companies to their offshore affiliated entities must be supported by bona fide business transactions.

On September 19, 2014, Beijing Pioneer entered into a master exclusive service agreement with New Oriental China to enable the Company’s wholly owned subsidiaries in China to receive substantially all of the economic benefits of New Oriental China and its schools and subsidiaries. Under the master exclusive service agreement, Beijing Pioneer has the exclusive right to provide or designate any entities affiliated with it to provide New Oriental China and its schools and subsidiaries the technical and business support services, including new enrollment system development service, sale of educational software and other operating services. Each service provider has the right to determine the fees associated with the services it provides based on the technical difficulty and complexity of the services and the actual labor costs it incurs for providing the services during the relevant period. The term of this agreement is ten years and will be automatically extended upon the expiration. Beijing Pioneer may terminate the agreement at any time with a 30-day prior written notice to New Oriental China, whereas none of New Oriental China and its schools and subsidiaries can terminate this agreement. The various existing service agreements mentioned in Note 1 will remain effective after the inclusion of the master exclusive service agreement; however, if they have any conflict with the terms and conditions of the master exclusive service agreement, the master exclusive service agreement will prevail. The master exclusive service agreement was effective on September 19, 2014.
