The VIE arrangements

Due to PRC legal restrictions on foreign ownership and investment in the education business in China, aside from the Group's personalized premium tutoring services in Beijing conducted by the Company’s wholly owned PRC subsidiaries, Huanqiu Zhikang and Zhixuesi Beijing, the Group provides and plans to provide most of its services in the PRC through its VIEs including Xueersi Education, Xueersi Network, Xinxin Xiangrong, Lebai Education and their subsidiaries and schools.

To provide the Company the power to control and the ability to receive the expected residual returns of the VIEs and their subsidiaries and schools, the Company's wholly owned subsidiary, TAL Beijing, entered into a series of contractual arrangements with Xueersi Education, Xueersi Network and their respective shareholders on February 12, 2009 and August 12, 2009, including exclusive business service agreements, which were superseded by the Exclusive Business Cooperation Agreement entered into on June 25, 2010. TAL Beijing entered into a series of contractual arrangements with Xinxin Xiangrong on August 4, 2015. Besides, in connection with the Company's acquisition of Firstleap during fiscal year 2016, Lebai Information, a wholly owned PRC subsidiary of Firstleap, entered into a series of contractual arrangements on October 26, 2015 with Lebai Education and its sole shareholder, Xueersi Education, which is a VIE of the Group.

The VIEs and their subsidiaries and schools hold various licenses upon which the Group’s business depends. A substantial majority of the Group’s employees who provide the Group’s services are hired by the VIEs and their subsidiaries and schools, and the VIEs and their subsidiaries and schools lease a substantial majority of the properties upon which the Group’s services are delivered. The net revenue from the VIEs and their subsidiaries and schools accounted for 94.1% of the Group’s total net revenue for fiscal year ended February 28, 2018.

Through the below contractual arrangements, TAL Beijing and Lebai Information have (1) the power to direct the activities of the VIEs and their subsidiaries and schools that most significantly affect their economic performance and (2) the right to receive substantially all the benefits from the VIEs and their subsidiaries and schools. They are therefore considered the primary beneficiaries of the VIEs and their subsidiaries and schools, and accordingly, the results of operations, assets and liabilities of the VIEs and their subsidiaries and schools are consolidated in the Group's financial statements.

Series of exclusive technology support and service agreements: Pursuant to Exclusive Business Cooperation Agreement entered into on June 25, 2010, by and among TAL Beijing, Xueersi Education, Xueersi Network, and the shareholders of Xueersi Education and Xueersi Network, TAL Beijing or its designated affiliates have the exclusive right to provide each of Xueersi Education and Xueersi Network and their subsidiaries and schools comprehensive intellectual property licensing and various technical and business support services. Pursuant to the Exclusive Business Service Agreement entered into by and among TAL Beijing, Xinxin Xiangrong and its shareholders on August 4, 2015, TAL Beijing and its designated affiliates have the exclusive right to provide Xinxin Xiangrong and its subsidiaries and schools (if any) comprehensive intellectual property licensing and various technical and business support services. The agreements are effective within the operation term of TAL Beijing, its subsidiaries and schools according to PRC Law, unless earlier terminated by mutual agreement of all parties.

Lebai Information, Lebai Education and its sole shareholder, subsidiaries and schools have entered into an Exclusive Business Service Agreement on October 26, 2015, the terms of which are substantially the same as the agreement of Xinxin Xiangrong summarized above. The term of such agreement is 10 years and will be renewed for another 10 years at Lebai Information’s discretion.

The services under each of these agreements include, but are not limited to, employee training, technology development, transfer and consulting services, public relation services, market survey, research and consulting services, market development and planning services, human resource and internal information management, network development, upgrade and ordinary maintenance services, and software and trademark licensing and other additional services as the parties may mutually agree from time to time. TAL Beijing, Lebai Information or their designated affiliates, owns the exclusive intellectual property rights developed in the performance of these agreements. As consideration for these services, TAL Beijing, Lebai Information or their designated affiliates are entitled to charge the VIEs and VIEs' subsidiaries and schools service fees annually or regularly, and adjust the service fee rates from time to time at their discretion.

Call option agreement: Pursuant to the call option agreement entered into on February 12, 2009, by and among TAL Beijing, Xueersi Education, Xueersi Network and their respective shareholders, the respective shareholders of Xueersi Education and Xueersi Network unconditionally and irrevocably granted TAL Beijing or its designated party an exclusive option to purchase from Xueersi Education and Xueersi Network' shareholders, to the extent permitted under PRC law, part of or all the equity interests in Xueersi Education and Xueersi Network, as the case may be, for the minimum amount of consideration permitted by the applicable law without any other conditions.

TAL Beijing, Xinxin Xiangrong and the shareholders of Xinxin Xiangrong have entered into a call option agreement on August 4, 2015. Lebai Information, Lebai Education and the sole shareholder of Lebai Education have entered into a call option agreement on October 26, 2015, the terms of which are substantially the same as the call option agreement summarized above.

Under each of these agreements, TAL Beijing or Lebai Information has sole discretion to decide when to exercise the option, and whether to exercise the option in part or in full. Unless earlier terminated by mutual agreement of all parties, these agreements shall remain effective until TAL Beijing and Lebai Information exercise their purchase right to purchase all the VIEs' equity interests according to these agreements.

Equity pledge agreement: Pursuant to the equity pledge agreements, dated on February 12, 2009, by and among TAL Beijing, Xueersi Education, Xueersi Network and the respective shareholders of Xueersi Education and Xueersi Network, and supplemental agreements, dated on June 25, 2010, by and among TAL Beijing, Xueersi Education, Xueersi Network and their respective shareholders, the shareholders of Xueersi Education and Xueersi Network unconditionally and irrevocably pledged all of their equity interests, including the right to receive declared dividends and the voting rights, in the Xueersi Education and Xueersi Network to TAL Beijing to guarantee Xueersi Education and Xueersi Network's performance of their obligations under the exclusive technology support and service agreements. The shareholders of Xueersi Education and Xueersi Network agree that, without prior written consent of TAL Beijing, they will not transfer or dispose the pledged equity interests or create or allow any encumbrance on the pledged equity interests that would prejudice TAL Beijing's interest.

TAL Beijing, Xinxin Xiangrong and the shareholders of Xinxin Xiangrong have entered into an equity pledge agreement on August 4, 2015. Lebai Information, Lebai Education and the sole shareholder of Lebai Education have entered into an equity pledge agreement on October 26, 2015, the terms of which are substantially the same as the agreements summarized above. These agreements are effective on the date of execution and terminate when all the secured rights under the relevant agreements, as the case may be, are completely fulfilled or terminated in accordance thereof.

Letter of Undertaking: All of the shareholders of Xueersi Education and Xueersi Network have executed a letter of undertaking to covenant with and undertake to TAL Beijing that, if, as the respective shareholders of Xueersi Education and Xueersi Network, such shareholders receive any dividends, interests, other distributions or remnant assets upon liquidation from Xueersi Education and Xueersi Network, such shareholders shall, to the extent permitted by applicable laws, regulations and legal procedures, remit all such income after payment of any applicable tax and other expenses required by laws and regulations to TAL Beijing without any compensation therefore. All the shareholders of Xinxin Xiangrong have made similar undertakings in the option agreement dated August 4, 2015, described above. The sole shareholder of Lebai Education has made similar undertakings in the power of attorney, dated October 26, 2015, described below.

Power of attorney: The shareholders of the VIEs have executed an irrevocable power of attorney appointing TAL Beijing or Lebai Information, as applicable, or any person designated by TAL Beijing or Lebai Information as their attorney-in-fact to vote on their behalf on all matters of the VIEs requiring shareholder approval under PRC laws and regulations and the articles of association of each of the VIEs on August 12, 2009, August 4, 2015 and October 26, 2015, respectively. These agreements remain effective during the entire period during which they are shareholders of the VIEs.

The articles of associations of each of the VIEs state that the major rights of the shareholders in shareholders' meeting include the power to approve the operating strategy and investment plan, elect the members of board of directors and approve their compensation and review and approve annual budget and earning distribution plan. Therefore, through the irrevocable power of attorney arrangement TAL Beijing or Lebai Information has the ability to exercise effective control over each of the VIEs respectively through shareholder votes and, through such votes, to also control the composition of the board of directors. As a result of these contractual rights, the Company has the power to direct the activities of each of the VIEs that most significantly impact their economic performance.

Spousal consent letter: The spouse of each shareholder of the VIEs has entered into a spousal consent letter to acknowledge that she is aware of, and consents to, the execution by her spouse of the call option agreement described above. Each spouse further agrees that she will not take any actions or raise any claims to interfere with the performance by her spouse of the obligations under the above mentioned agreements.

Deed of undertaking: On June 24, 2013 and July 29, 2013, the Company and Mr. Bangxin Zhang executed a deed of undertaking dated June 24, 2013 and a side letter dated July 29, 2013, respectively (collectively, the “Deed”). Pursuant to the Deed, Mr. Bangxin Zhang has irrevocably covenanted and undertaken to the Company that:

⋅

as long as Mr. Bangxin Zhang owns shares in the Company, whether legally or beneficially, and directly or indirectly (including shares held through Mr. Bangxin Zhang’s personal holding company Bright Unison Limited or any other company, trust, nominee or agent, if any), representing more than 50% of the aggregate voting power of the then total issued and outstanding shares of the Company;

⋅

Mr. Bangxin Zhang will not, directly or indirectly, (i) requisition or call any meeting of shareholders for the purpose of removing or replacing any of existing directors or appointing any new director, or (ii) propose any resolution at any of shareholders meetings to remove or replace any of existing directors or appoint any new director; and should any meeting of shareholders be called by the board of directors or requisitioned or called by shareholders for the purpose of removing or replacing any of the directors or appointing any new director, or if any resolution is proposed at any of shareholder meetings to remove or replace any of the directors or appoint any new director, the maximum number of votes which Mr. Bangxin Zhang will be permitted to exercise shall be equal to the total aggregate number of votes of the then total issued and outstanding shares of the Company held by all members of the Company, other than shares which are owned, whether legally or beneficially, and directly or indirectly by Mr. Bangxin Zhang, less one vote; and

⋅

Mr. Bangxin Zhang will not cast any votes he has as a director or shareholder (if applicable) on any resolutions or matters concerning enforcing, amending or otherwise relating to the Deed being considered or voted upon by board of directors or shareholders, as the case may be.

In the opinion of Maples and Calder (Hong Kong) LLP, the Company's Cayman Islands legal counsel, the deed of undertaking constitutes the legal, valid and binding obligations of Mr. Bangxin Zhang, which cannot be unilaterally revoked by Mr. Bangxin Zhang, and is enforceable in accordance with its terms under existing Cayman Islands laws.

Risks in relation to the VIE structure

The Company believes that TAL Beijing and Lebai Information's contractual arrangements with the VIEs and their respective subsidiaries, schools and shareholders are in compliance with PRC law and are legally enforceable. However, uncertainties in the PRC legal system could limit the Company's ability to enforce these contractual arrangements. If the legal structure and contractual arrangements were found to be in violation of any existing PRC laws and regulations, the Group would be subject to fines or potential actions by the relevant PRC regulatory authorities with broad discretions, which could include:

⋅

revoke the Group's business and operating licenses;

⋅

require the Group to discontinue or restrict its operations;

⋅

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

⋅

restrict the Group's right to collect revenues or impose fines;

⋅

block the Group's websites;

⋅

require the Group to restructure the operations in such a way as to compel the Group to establish a new enterprise, re-apply for the necessary licenses or relocate its businesses, staff and assets;

⋅

impose additional conditions or requirements with which the Group may not be able to comply; or

⋅

take other regulatory or enforcement actions against the Group that could be harmful to its business.

The imposition of any of these penalties could result in a material adverse effect on the Company's ability to conduct the Group's business. In addition, if the imposition of any of these penalties causes the Company to lose the rights to direct the activities of the VIEs, and the VIEs' subsidiaries and schools, or the right to receive their economic benefits, the Company would no longer be able to consolidate the VIEs, and the VIEs' subsidiaries and schools. The Company does not believe that any penalties imposed or actions taken by the PRC government would result in the liquidation or dissolution of the Company, TAL Beijing, Lebai Information, or the VIEs and their respective subsidiaries and schools.

The four legal owners of Xueersi Education and Xueersi Network are Mr. Bangxin Zhang, Mr. Yachao Liu, Mr. Yunfeng Bai, and Mr. Yundong Cao, and the three legal owners of Xinxin Xiangrong are Mr. Bangxin Zhang, Mr. Yachao Liu and Mr. Yunfeng Bai and the sole legal owner of Lebai Education is Xueersi Education. Mr. Bangxin Zhang, Mr. Yachao Liu and Mr. Yunfeng Bai are shareholders and directors or officers of TAL Education Group. Xueersi Education is a VIE of the Group. The interests of Mr. Bangxin Zhang, Mr. Yachao Liu, Mr. Yunfeng Bai and Mr. Yundong Cao as beneficial owners of Xueersi Education, Xueersi Network and Xinxin Xiangrong may differ from the interests of the Group as a whole, since these parties’ respective equity interests in Xueersi Education, Xueersi Network and Xinxin Xiangrong may conflict with their respective equity interests in the Group. When conflicts of interest arise, it is possible that any or all of these individuals may not act in the best interests of the Group, and such conflicts may not be resolved in the Group’s favor. In addition, these individuals may breach, or cause Xueersi Education, Xueersi Network and Xinxin Xiangrong, their subsidiaries and schools to breach, or refuse to renew, the existing contractual arrangements the Group has with them and Xueersi Education, Xueersi Network and Xinxin Xiangrong, their subsidiaries and schools. Other than the aforementioned deed of undertaking the Group entered with Mr. Bangxin Zhang, the Group currently does not have any arrangements to address potential conflicts of interest between these individuals and the Company. To a large extent, the Group relies on the legal owners of Xueersi Education, Xueersi Network and Xinxin Xiangrong to abide by the laws of the Cayman Islands and China, which provide that directors and officers owe a fiduciary duty to the Company that requires them to act in good faith and in the best interests of the Company and not to use their positions for personal gains. If the Group cannot resolve any conflict of interest or dispute between it and these individuals, the Group would have to rely on legal proceedings, which could result in disruption of its business and subject it to substantial uncertainty as to the outcome of any such legal proceedings.

Accounting Policies [Abstract]

Organization, Consolidation, Basis of Presentation, Business Description and Accounting Policies [Text Block]

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 (“U.S. GAAP”).

Basis of consolidation

The consolidated financial statements include the financial statements of the Company, its subsidiaries, which are accounted for under the voting interest model, and its VIEs, VIEs’ subsidiaries and schools consolidated under the variable interest entity consolidation model. All inter-company transactions and balances have been eliminated upon consolidation.

Consolidation of Variable Interest Entities

The Company through TAL Beijing and Lebai Information, wholly owned foreign enterprises, has executed a series of contractual agreements with its VIEs, the VIEs’ subsidiaries and schools and the VIEs’ nominee shareholders. For a description of these contractual arrangements, see “Note 1 Organization and Principal Activities—The VIE Arrangements”. These contractual agreements do not provide TAL Beijing and Lebai Information with an equity interest in legal form in the VIEs. As the Company holds no legal form of equity ownership in the VIEs, the Company applied the variable interest entity consolidation model as set forth in Accounting Standards Codification 810, Consolidation (“ASC 810”) instead of the voting interest model of consolidation.

By design, the contractual agreements provide TAL Beijing and Lebai Information with a right to receive benefits equal to substantially all of the net income of these entities, and thus under ASC 810, these agreements are considered variable interests. Subsequent to identifying any variable interests, any party holding such variable interests must determine if the entity in which the interest is held is a variable interest entity and subsequently which reporting entity is the primary beneficiary of, and should therefore consolidate the variable interest entity. Among other reasons, an entity is considered a variable interest entity if the holders of the equity investment at risk in the entity, as a group, lack any one of the following characteristics of a controlling financial interest:

The power, through voting rights or similar rights, to direct the activities of the entity that most significantly impact the entity’s economic performance

The obligation to absorb the entity’s expected losses, or

The right to receive the entity’s expected residual returns

A reporting entity is considered to be the primary beneficiary, and thus the accounting parent, of a variable interest entity if it possesses both: (a) the power to direct the activities that most significantly impact the economic performance of the variable interest entity and (b) the obligation to absorb losses and/or the right to receive benefits from the entity that could potentially be significant to the variable interest entity.

As a result of the contractual arrangements, the nominee shareholders of the VIEs lack the characteristics of a controlling financial interest in the VIEs and therefore the VIEs are considered to be variable interest entities under ASC 810. The contractual arrangements, by design, provide TAL Beijing and Lebai Information the power to direct the activities that most significantly impact the economic performance of the VIEs and the right to receive substantially all the benefits of the VIEs, which causes TAL Beijing and Lebai Information to be the primary beneficiaries of the VIEs, and accordingly TAL Beijing and Lebai Information consolidate their operations.

Determining whether TAL Beijing and Lebai Information are the primary beneficiaries requires a careful evaluation of the facts and circumstances, including whether the contractual agreements are substantive under the applicable legal and financial reporting frameworks, i.e. PRC law and U.S. GAAP. The Company continually reviews its corporate governance arrangements to ensure that the contractual agreements are indeed substantive.

The Company has determined that the contractual agreements are in fact valid and legally enforceable. Such arrangements were entered into in order to comply with the underlying legal and/or regulatory restrictions that govern the ownership of a direct equity interest in the VIEs. In the opinion of the Company's PRC counsel, Tian Yuan Law Firm, the contracts are legally enforceable under PRC law. See “Note 1 Organization and Principal Activities—The VIE Arrangements”.

The Company has considered the existence of related party relationships, e.g. ownership of an equity interest in the Company and the VIEs, and the effect that might have on the enforceability of the contractual agreements and in turn whether they are substantive. The Company believes there are no barriers to exercise its rights under the contracts and therefore they are substantive and appropriately considered in the consolidation analysis in accordance with ASC 810. In assessing the shareholdings of certain individual parties in the Company and in the VIEs, specifically Mr. Bangxin Zhang, the Company acknowledges that from November 23, 2011, Mr. Bangxin Zhang, a majority nominee shareholder in the VIEs, also holds a majority voting interest in the Company, which resulted from conversion of Class B common shares with ten votes per share to Class A common shares with one vote per share by other shareholders. Therefore, the Company has reassessed the consolidation of its VIEs.

Although the contractual arrangements between TAL Beijing and its VIEs were designed to provide TAL Beijing with the characteristics of a controlling financial interest regardless of the respective shareholdings of Mr. Bangxin Zhang, during the period between November 23, 2011 and June 24, 2013, Mr. Bangxin Zhang’s majority voting interest in the Company, when combined with his status as a majority nominee shareholder in the VIEs, could have constrained the ability of the Company to exercise its rights under the contractual agreements. This is due to the fact that Mr. Bangxin Zhang’s majority voting interest in the Company provided him with the legal ability to control the composition of a majority of the board of directors and therefore may have provided him with the legal ability to affect whether or not the Company could exercise the rights contained in the contractual agreements. Mr. Bangxin Zhang did not exercise this power at any time during the period in which he held a majority voting interest in the Company and during such period. In fact, there was no change in the composition of the board of directors or in the day-to-day operations of the Company during the period.

On June 24, 2013 and July 29, 2013, the Company and Mr. Bangxin Zhang executed a deed of undertaking dated June 24, 2013 and a side letter dated July 29, 2013, respectively (collectively, the “Deed”). Pursuant to the terms of the Deed, as long as Mr. Bangxin Zhang owns a majority voting interest, whether legally or beneficially, and directly or indirectly, in Company, (1) Mr. Bangxin Zhang cannot requisition or call a meeting of shareholders or propose a shareholders resolution to appoint or remove a director, (2) if shareholders are asked to appoint or remove a director, the maximum number of votes which Mr. Bangxin Zhang will be permitted to exercise in connection with such shareholder approval is equal to the total aggregate number of votes of the then total issued and outstanding shares of the Company held by all members of the Company, other than shares which are owned, whether legally or beneficially, and directly or indirectly by Mr. Bangxin Zhang, less one vote and (3) if shareholders or board of directors are asked to consider or approve any matter related to the Deed, Mr. Bangxin Zhang cannot exercise his voting power.

Upon execution of the Deed, despite his ownership of and as long as he holds a majority voting interest, whether legally or beneficially, and directly or indirectly, in the Company, Mr. Bangxin Zhang will (1) not be permitted to requisition or call a meeting of shareholders or propose a shareholders resolution to appoint or remove a director, (2) in relation to any shareholder approvals to appoint or remove a director, only be permitted to exercise up to the number of votes equal to the total aggregate number of votes of the then total issued and outstanding shares of the Company held by all members of the Company, other than shares which are owned, whether legally or beneficially, and directly or indirectly by Mr. Bangxin Zhang, less one vote and (3) in relation to shareholders’ or board of directors’ consideration or approval of any matter related to the Deed, Mr. Bangxin Zhang cannot exercise his voting power. The terms of the Deed prevents Mr. Bangxin Zhang from controlling the rights of the Company as it relates to the contractual agreements, and accordingly, the Company retains a controlling financial interest in the VIEs and would consolidate them as the VIEs’ primary beneficiary.

Please see Note 1 for the presentation of abbreviated financial information of the VIEs and the Group without the VIEs, after elimination of intercompany balances and transactions.

Use of estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect reported amounts of assets, liabilities, revenue, costs, and expenses, and the disclosure of contingent assets and liabilities. Actual results could differ from those estimates. Significant accounting estimates reflected in the Group's consolidated financial statements include purchase price allocation relating to business acquisitions, valuation allowance for deferred tax assets, the useful lives of property and equipment and intangible assets, impairment of intangible assets, long-lived assets, goodwill and long term investments, fair value assessment of long-term investments and consolidation of variable interest entities.

Cash and cash equivalents

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

Restricted cash

The Group's restricted cash is related to deposits required by PRC government authorities for establishing new schools and subsidiaries, cash deposit relating to potential acquisition and interest deposits in connection with the term and revolving facilities agreement.

Short-term investments

Short-term investments include wealth management products, which are mainly deposits with variable interest rates placed with financial institutions and are restricted as to withdrawal and use. The Group classifies the wealth management products as held-to-maturity securities. The original maturities of the short-term investments are greater than three months, but less than twelve months.

For investment products indexed to an underlying stock or stock market, the Group elects the fair value method to record them at fair value in accordance with ASC 825 Financial Instruments. Changes in the fair value are reflected in the consolidated statements of operations.

The Group's trading securities are comprised of investment portfolio with underlying securities publicly traded in active markets. The investments are reported at fair value and changes in the fair value are reflected in the consolidated statements of operations.

Property and equipment, net

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

Building	35-40 years
Computer, network equipment and software	3 years
Vehicles	4-5 years
Office equipment and furniture	3-5 years
Leasehold improvement	Shorter of the lease term or estimated useful lives

Business combinations

Business combinations are recorded using the acquisition method of accounting. The assets acquired, the liabilities assumed, and any noncontrolling interests of the acquiree at the acquisition date, if any, are measured at their fair values as of the acquisition date. Goodwill is recognized and measured as the excess of the total consideration transferred plus the fair value of any noncontrolling interest of the acquiree and fair value of previously held equity interest in the acquiree, if any, at the acquisition date over the fair values of the identifiable net assets acquired. Common forms of the consideration made in acquisitions include cash and common equity instruments. Consideration transferred in a business acquisition is measured at the fair value as of the date of acquisition.

Where the consideration in an acquisition includes contingent consideration 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.

In a business combination achieved in stages, the Group remeasures the previously held equity interest in the acquiree immediately before obtaining control at its acquisition-date fair value and the remeasurement gain or loss, if any, is recognized in the consolidated statements of operations.

Business combinations occurred during the year ended February 28, 2018 are disclosed in Note 3.

Acquired intangible assets, net

Acquired intangible assets other than goodwill consist of trade name and domain names, copyrights, student and user base, technology, partnership agreements, non-compete agreements, licenses, customer relationship, concession, school cooperation agreements and teaching materials, and are carried at cost, less accumulated amortization and impairment. Amortization of finite-lived intangible assets is computed using the straight-line method over the estimated useful lives. The amortization periods by intangible asset classes are as follows:

Trade name and domain names	3.0-10.4 years
Copyrights	3.0-5.5 years
Student and user base	1.3-7.0 years
Technology	5.0-6.0 years
Partnership agreements	2.6-4.5 years
Non-compete agreements	2.0-3.0 years
Licenses	1.7-5.0 years
Customer relationship	3.0-5.0 years
Concession	3.0-5.0 years
School cooperation agreements	5.0-6.4 years
Teaching materials	10.0 years

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.

Goodwill

The excess of the purchase price over the fair value of net assets acquired is recorded on the consolidated balance sheets as goodwill. Goodwill is not amortized, but tested for impairment annually or more frequently if event and circumstances indicate that it might be impaired.

ASC 350-20 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. Absent from any impairment indicators, the Group performs its annual impairment test on the last day of each fiscal year.

The Group does not choose to perform the assessment of qualitative factors for goodwill impairment and performs its annual impairment test using a two-step approach. The first step compares the fair value of a reporting unit to its carrying amount, including goodwill. If the fair value of the reporting unit is greater than its carrying amount, goodwill is not considered impaired and the second step is not required. If the fair value of the reporting unit is less than its carrying amount, the second step of the impairment test measures the amount of the impairment loss, if any, by comparing the implied fair value of goodwill to its carrying amount. If the carrying amount of goodwill exceeds its implied fair value, an impairment loss is recognized equal to that excess. The implied fair value of goodwill is calculated in the same manner that goodwill is calculated in a business combination, whereby the fair value of the reporting unit is allocated to all of the assets and liabilities of that unit, with the excess purchase price over the amounts assigned to assets and liabilities representing the implied fair value of goodwill.

The Group recognized no impairment loss on goodwill for any of the periods presented.

Long-term investments

The Group’s long-term investments consist of cost method investments, equity method investments, available-for-sale investments, fair value option investments and held-to-maturity investments.

Cost method investments

For investee companies over which the Group neither has significant influence nor control through investment in common shares or in-substance common shares and which do not have readily determinable fair value, the Group accounts for the investments in cost method, under which the Group carries the investments 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 other-than-temporary impairment 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.

Equity method investments

Investee companies over which the Group has the ability to exercise significant influence, but does not have a controlling interest through investment in common shares or in-substance common shares, 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 also considered in determining whether the equity method of accounting is appropriate. For certain investments in limited partnerships, where the Group holds less than a 20% equity or voting interest, the Group may also have significant influence.

Under the equity method, the Group initially records its investment at cost and subsequently recognizes the Group’s proportionate share of each equity investee’s net income or loss after the date of investment into earnings and accordingly adjusts the carrying amount of the investment. If financial statements of an investee cannot be made available within a reasonable period of time, the Group records its share of the net income or loss of an investee on a one quarter lag basis in accordance with ASC 323-10-35-6.

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

Available-for-sale investments

For investments in investees' preferred shares which are determined to be debt securities, the Group accounts for them as available-for-sale investments when they are not classified as either trading or held-to-maturity investments. Available-for-sale investments are reported at fair value, with unrealized gains and losses recorded in accumulated other comprehensive income as a component of shareholders’ equity.

Realized gains and losses and provision for decline in value judged to be other than temporary, if any, are recognized in the consolidated statements of operations.

Fair value option investments

The Group elected the fair value option to account for certain investments whereby the change in fair value is recognized in the consolidated statements of operations.

Held-to-maturity investments

Long-term investments include wealth management products, which are mainly deposits with variable interest rates placed with financial institutions and are restricted as to withdrawal and use. The Group classifies the wealth management products as “held-to-maturity” securities. The original maturities of the investments are two years.

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 pricing 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 assets or liabilities 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.

Fair value of financial instruments is disclosed in Note 14.

Revenue recognition

The Group recognizes revenue when persuasive evidence of an arrangement exists, delivery has occurred, the sales price is fixed or determinable, and collectability is reasonably assured. Revenue is reported net of business tax, value added tax (“VAT”) and related surcharge.

The primary sources of the Group's revenues are as follows:

(a)

Educational programs and services

The educational programs and services primarily consist of after-school group tutoring (including Xueersi small class, Mobby courses and Firstleap) and after-school one-on-one tutoring. Tuition revenue is generally collected in advance and is initially recorded as deferred revenue. Tuition revenue is recognized proportionately as the tutoring sessions are delivered. The revenue for educational programs and services for the years ended February 29, 2016, February 28, 2017 and February 28, 2018 are $585,046,737, $950,417,433 and $1,507,898,108, respectively.

Generally, for Xueersi small class courses, the Group offers refunds for any remaining classes to students who decide to withdraw from a course. The refund is equal to and limited to the amount related to the undelivered classes. For most Mobby courses, the Group offers refunds equal to and limited to the amount related to the undelivered classes to students who withdraw from a course, provided the course is less than two-third completed at the time of withdrawal. After two-third of the course is completed, no refund will be provided. For Firstleap, the Group offers refunds for any remaining classes to students who decide to withdraw from a course, provided the course is less than half completed at the time of withdrawal. After half of the course is completed, no refund will be provided. For personalized premium services, a student can withdraw at any time and receive a refund equal to and limited to the amount related to the undelivered classes. The refund is recorded as a reduction of the related deferred revenue and has no impact on recognized revenue. Historically, the Group has not experienced material refunds on recognized revenue, and as such, no accrual for estimated refunds is deemed necessary.

The Group distributes coupons to attract both existing and prospective students to enroll in its courses. The coupon has fixed dollar amounts and can only be used against future courses. The coupon is accounted for as a reduction of revenue when the relevant revenue is recognized in the consolidated statements of operations.

(b)

Online education services through www.xueersi.com

The online education services provided by the Group through www.xueersi.com to its students include live class and pre-recorded course content and the revenue for the years ended February 29, 2016, February 28, 2017 and February 28, 2018 are $24,710,561, $48,878,453 and $120,719,041, respectively.

Students enroll for online courses through www.xueersi.com by the use of prepaid study cards or payment to the Group's online accounts. The proceeds collected are initially recorded as deferred revenue. For live class courses, revenues are recognized proportionately as the tutoring sessions are delivered. For pre-recorded course content, revenues are recognized on a straight line basis over the subscription period from the date in which the students activate the courses to the date in which the subscribed courses end. Refunds are provided to the students who decide to withdraw from the subscribed courses within the course offer period and a proportional refund is based on the percentage of untaken courses to the total courses offered. Historically, the Group has not experienced material refunds on the recognized revenue, and as such, no accrual for estimated refunds is deemed necessary.

(c)

Others

Other revenues are primarily derived from 1) advertising services provided on the Group's online platforms; 2) educational materials sales; and 3) consulting service and test preparation courses related to overseas study. Revenue is recognized after a contract is signed, the price is fixed or determinable, services or products are delivered and collection is reasonably assured. Other revenues for the years ended February 29, 2016, February 28, 2017 and February 28, 2018 are $10,191,479, $43,803,769 and $86,398,835, respectively.

Share-based compensation

Share-based payment transactions with employees are measured based on the grant date fair value of the equity instrument and recognized as compensation expense on a straight-line basis over the requisite service period, with a corresponding impact reflected in additional paid-in capital. Forfeitures are recognized as they occur.

Value added tax

Pursuant to the PRC tax laws, in case of any product sales, generally the VAT rate is 3% of the gross sales for small scale VAT payer and 17% of the gross sales for general VAT payer. TAL Beijing and Xueersi Education are deemed as general VAT payer since January 2010 and August 2010 respectively for the sales of guidance materials and the intercompany sales of self-developed software. For general VAT payer, VAT on sales is calculated at 17% on revenue from product sales and paid after deducting input VAT on purchases. The net VAT balance between input VAT and output VAT is reflected in the accounts under other taxes payable.

The Group's online education services and inter-company technical services are subject to VAT at the rate of 6% of revenue for general VAT payer and hence Beijing Xintang Sichuang, TAL Beijing, Xueersi Education and Yidu Huida are deemed as general VAT payer at the rate of 6% since September 2012. Zhixuesi Beijing was deemed as general VAT payer at the rate of 6% since August 2013 and elects a simple VAT collection method since November 2016. Xinxin Xiangrong and Pengxin TAL are deemed general VAT payers at the rate of 6% since June 2015 and May 2016, respectively. Yizhen Xuesi was deemed as general VAT payer at the rate of 6% since November 2016.

Xueersi Education enjoys VAT exemption for book sales from February 2014 to December 2017. Since January 2018, it is subject to a VAT rate of 17% for its book sales.

Since May 2016, in accordance with Cai Shui [2016] No. 68, non-academic education service providers who are general VAT payer could elect a simple VAT collection method and apply for a 3% VAT rate. The Group’s schools which were previously subject to business tax are now subject to a VAT rate of 3%.

Operating leases

Leases where substantially all the rewards and risks of the ownership of the assets remain with the leasing companies are accounted for as operating leases. Payments made for the operating leases are charged to the consolidated statements of operations on a straight-line basis over the shorter of the lease term or estimated useful life, and have been included in the consolidated statements of operations.

Advertising costs

The Group expenses advertising costs as incurred. Total advertising costs incurred were $2,637,778, $5,331,088 and $22,474,379 for the years ended February 29, 2016, February 28, 2017 and February 28, 2018, respectively, and have been included in selling and marketing expenses in the consolidated statements of operations.

Government subsidies

The Group reports government subsidies as other income when received from local government authority with no limitation on the use of the subsidies. The Group receives government subsidies related to government sponsored projects and records such government subsidies as a liability when it is received and records it as other income when the performance obligation is met or fulfilled.

Government subsidies received totaled $3,301,463, $3,107,229 and $4,559,849 for the years ended February 29, 2016, February 28, 2017 and February 28, 2018, respectively. The Group recorded $3,327,169, $3,113,877 and $4,650,059 government subsidies as other income for the years ended February 29, 2016, February 28, 2017 and February 28, 2018, respectively.

Foreign currency translation

The functional and reporting currency of the Company is the United States dollar. The functional currency of the Company's PRC subsidiaries, VIEs and VIEs' subsidiaries and schools in the PRC is Renminbi (“RMB”).

Monetary assets and liabilities denominated in currencies other than the applicable functional currencies are translated into the functional currencies at the prevailing rates of exchange at the balance sheet date. Nonmonetary assets and liabilities are remeasured into the applicable functional currencies at historical exchange rates. Transactions in currencies other than the applicable functional currencies during the year are converted into the functional currencies at the applicable rates of exchange prevailing at the transaction dates. Transaction gains and losses are recognized in the consolidated statements of operations. For the years ended February 29, 2016, February 28, 2017 and February 28, 2018, the Group recorded exchange loss of $5,186,540, $1,288,132 and exchange gain of $3,323,723, respectively, in other expense/income in the consolidated statements of operations.

For translating the results of the PRC subsidiaries into the functional currency of the Company, assets and liabilities are translated from each subsidiary's functional currency to the reporting currency at the exchange rate on the balance sheet date. Equity amounts are translated at historical exchange rates, and revenues, expenses, gains and losses are translated using the average rate for the period. Translation adjustments are reported as cumulative translation adjustments and are shown as a separate component of other comprehensive income in the consolidated statements of changes in equity and comprehensive income.

Foreign currency risk

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. Cash and cash equivalents, and restricted cash of the Group included aggregate amounts of $316,351,713 and $466,721,083 as of February 28, 2017 and February 28, 2018, respectively, which were denominated in RMB.

Income taxes

Deferred income taxes are recognized for temporary differences between the tax basis of assets and liabilities and their reported amounts in the financial statements, net of operating loss carry forwards and credits, by applying enacted statutory tax rates applicable to future years. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion or all of the deferred tax assets will not be realized. Current income taxes are provided for in accordance with the laws and regulations applicable to the Group as enacted by the relevant tax authorities.

Comprehensive income

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

Concentration of credit risk

Financial instruments that potentially expose the Group to significant concentration of credit risk consist primarily of cash and cash equivalents, short-term investments and restricted cash. The Group places its cash and cash equivalents, short-term investments and restricted cash in financial institutions with high credit ratings.

Financial instruments

The Group's financial instruments consist primarily of cash and cash equivalents, restricted cash, short-term investments, long-term investments accounted for available-for-sale investments, fair value option investments and held-to-maturity investments, amounts due from related parties and amounts due to related parties, accounts payable, income tax payable, long-term debt and bond payable. The Group carries its available-for-sale investments and fair value option investments at fair value. The carrying amount of long-term debt approximates fair value as its interest rates are at the same level of current market yield for comparable debts. The carrying amounts of other financial instruments, except for bond payable and long-term held-to-maturity investments, approximate their fair values because of their generally short maturities. The bond payable and long-term held-to-maturity investments are recorded at amortized cost.

Net income per share

Basic net income per share is computed by dividing net income attributable to common shareholders of the Company by the weighted average number of common shares outstanding during the year. Diluted net income per 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. The Group has share options, non-vested shares and bond payable which could potentially dilute basic earnings per share in the future. To calculate the number of shares for diluted net income per share, the effect of the share options and non-vested shares is computed using the treasury stock method. The dilutive effect of the bond payable is computed using as-if converted method.

Recent accounting pronouncements adopted

In March 2016, the FASB issued ASU 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. The new guidance simplifies certain aspects related to income taxes, statement of cash flows, and forfeitures when accounting for share-based payment transactions. Certain of the amendments related to timing of the recognition of tax benefits and tax withholding requirements should be applied using a modified retrospective transition method. Amendments related to the presentation of the statement of cash flows should be applied retrospectively. All other provisions may be applied on a prospective or modified retrospective basis. 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. The Group adopted this standard on March 1, 2017 and has elected to account for forfeitures as they occur rather than applying an estimated forfeiture rate to share-based compensation expense. The adoption did not have a material impact on the Group’s financial position or results of operations. However, the retrospective application of cash paid for employee taxes on withheld shares from share-based awards resulted in a $9,436,440 and $19,463,487 reclassification of these cash outflows from operating activities to financing activities on our consolidated statements of cash flows for the years ended February 29, 2016 and February 28, 2017, respectively.

Recent accounting pronouncements not yet adopted

In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers (Topic 606).” ASU 2014-09 requires revenue recognition to depict the transfer of goods or services to customers in an amount that reflects the consideration that a company expects to be entitled to in exchange for the goods or services. To achieve this principle, a company must apply five steps including identifying the contract with a customer, identifying the performance obligations in the contract, determining the transaction price, allocating the transaction price to the performance obligations, and recognizing revenue when (or as) the company satisfies the performance obligations. Additional quantitative and qualitative disclosure to enhance the understanding about the nature, amount, timing, and uncertainty of revenue and cash flows is also required. ASU 2014-09 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017. In April 2016, the FASB issued ASU 2016-10, “Identifying Performance Obligations and Licensing.” ASU 2016-10 clarifies the following two aspects of ASU 2014-09: identifying performance obligations and licensing implementation guidance. The effective date of ASU 2016-10 is the same as the effective date of ASU 2014-09.

The Group expects to adopt ASU 2014-09 utilizing the modified retrospective method in the first quarter of fiscal year 2019. The Group has substantially completed an assessment of the impacts of the new standard to its existing portfolio of customer contracts. The Group does not believe the adoption of ASU 2014-09 would have a material effect on its current revenue recognition policies, except that it will be required to assess variable consideration included in its consulting service related to overseas study over the expected service period. The Group has also identified a provision under the new standard in relation to the incremental cost, commission fees, of obtaining a contract and will make judgments and estimates throughout the applicable periods. Certain additional financial statement disclosure are mandated by the new standard including disclosure of contract assets and contract liabilities as well as a disaggregated view of revenue.

In January 2016, the FASB issued a new pronouncement ASU 2016-01 Financial Instruments-Overall: Recognition and Measurement of Financial Assets and Financial Liabilities. The ASU requires equity investments (except those accounted for under the equity method of accounting or those that result in consolidation of the investee) to be measured at fair value with changes in fair value recognized in net income. The ASU also requires an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments.

ASU 2016-01 was further amended in February 2018 by ASU 2018-03, “Technical Corrections and Improvements to Financial Instruments—Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities”. This update was issued to clarify certain narrow aspects of guidance concerning the recognition of financial assets and liabilities established in ASU 2016-01. This includes an amendment to clarify that an entity measuring an equity security using the measurement alternative may change its measurement approach to a fair valuation method in accordance with Topic 820, Fair Value Measurement, through an irrevocable election that would apply to that security and all identical or similar investments of the same issued.

ASU 2016-01 and ASU 2018-03 are effective for public companies for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The new guidance permits early adoption of the own credit provision. Adoption of the amendment must be applied by means of a cumulative-effect adjustment to the balance sheet as of the beginning of the fiscal year of adoption, except for amendments related to equity instruments that do not have readily determinable fair values which should be applied prospectively. The Group will apply the new standard beginning March 1, 2018. For investments in equity securities without readily determinable fair values, the Group will elect to use the measurement alternative defined as cost, less impairments, adjusted by observable price changes. The Group anticipates that the adoption of ASU 2016-01 may increase the volatility of its other (expense)/income, as a result of the remeasurement of its equity securities upon the occurrence of observable price changes.

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). The guidance supersedes existing guidance on accounting for leases with the main difference being that operating leases are to be recorded in the statement of financial position as right-of-use assets and lease liabilities, initially measured at the present value of the lease payments. For operating leases with a term of 12 months or less, a lessee is permitted to make an accounting policy election not to recognize lease assets and liabilities. For public business entities, the guidance is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early application of the guidance is permitted. In transition, entities are required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. The Group is in the process of evaluating the impact that this guidance will have on its consolidated financial statements.

In June 2016, the FASB issued ASU 2016-13, Financial Instruments — Credit Losses (Topic 326), Measurement of Credit Losses on Financial Statements. This ASU requires a financial asset (or group of financial assets) measured at amortized cost basis to be presented at the net amount expected to be collected. The allowance for credit losses is a valuation account that is deducted from the amortized cost basis of the financial asset(s) to present the net carrying value at the amount expected to be collected on the financial asset. This Accounting Standards Update affects entities holding financial assets and net investment in leases that are not accounted for at fair value through net income. The amendments affect loans, debt securities, trade receivables, net investments in leases, off balance sheet credit exposures, reinsurance receivables, and any other financial assets not excluded from the scope that have the contractual right to receive cash. For public business entities, the amendments in this Update are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. All entities may adopt the amendments in this Update through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective (that is, a modified-retrospective approach). The Group is evaluating the impact of the adoption of this standard on its consolidated financial statements.

In November 2016, the FASB issued ASU 2016-18: Statement of Cash Flows (Topic 230): Restricted Cash. The amendments in this Update require that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The amendments in this Update do not provide a definition of restricted cash or restricted cash equivalents. The amendments in this Update are effective for public business entities for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted, including adoption in an interim period. The amendments in this Update should be applied using a retrospective transition method to each period presented. The Group is in the process of evaluating the impact of the Update on its consolidated financial statements.

In January 2017, the FASB issued ASU 2017-01: Business Combinations (Topic 805): Clarifying the Definition of a Business. The Update requires that when substantially all of the fair value of the gross assets acquired (or disposed of) is concentrated in a single identifiable asset or a group of similar identifiable assets, the set is not a business. This screen reduces the number of transactions that need to be further evaluated. If the screen is not met, the amendments in this Update (1) require that to be considered a business, a set must include, at a minimum, an input and a substantive process that together significantly contribute to the ability to create output and (2) remove the evaluation of whether a market participant could replace missing elements. Public business entities should apply the amendments in this Update to annual periods beginning after December 15, 2017, including interim periods within those periods. Early application of the amendments in this Update is allowed. The amendments in this Update should be applied prospectively on or after the effective date. No disclosures are required at transition. The Group is in the process of evaluating the impact of the Update on its consolidated financial statements.

In January 2017, the FASB issued ASU 2017-04: Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. To simplify the subsequent measurement of goodwill, the Board eliminated Step 2 from the goodwill impairment test. Under the amendments in this Update, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. An entity should apply the amendments in this Update on a prospective basis. An entity is required to disclose the nature of and reason for the change in accounting principle upon transition. A public business entity should adopt the amendments in this Update for its annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The Group is in the process of evaluating the impact of the Update on its consolidated financial statements.

BOND PAYABLE

On May 21, 2014, the Company issued $230,000,000 in aggregate principal amount of convertible bond due on May 15, 2019 (“the Bond”), unless earlier repurchased, converted or redeemed. The Bond bears interest at a rate of 2.5% per year, payable semiannually in arrears on May 15 and November 15 of each year, beginning on November 15, 2014.

The net proceeds from the Bond, after deducting the issuance costs, were $224,722,942. The Company has accounted for the Bond as a single instrument as bond payable. The value of the Bond is measured by the cash received. As of February 28, 2018, the fair value of the bond payable is $96,054,582, which is determined based on the quoted price in an active market (Level 1). Interest expense of $7,539,778 and $2,464,804 were recognized for the years ended February 28, 2017 and February 28, 2018, respectively.

The debt issuance costs of $5,277,058 were recorded as a reduction of the bond payable and amortized using the effective interest method over the period from issuance date to the earliest redemption date, May 15, 2017.

Effective on August 16, 2017, the Company adjusted the ratio of its American Depositary Shares (“ADSs”) to Class A common shares from one ADS representing two Class A common shares to three ADSs representing one Class A common shares. The information disclosed below have been given effect to the foregoing ADS to share ratio change (“Ratio Change”). In addition, as disclosed in Note 25, the Company declared and paid a cash dividend, which triggered the conversion adjustment provisions of the Bond.

In connection with the issuance of the Bond, the Company entered into capped call transactions (each a “Capped Call Transaction”) with three initial purchasers or their affiliates by purchasing 52,712,642 options, which is the number of adjusted ADS issuable upon conversion of the Bond in full, for $22,885,000. The Capped Call Transactions are expected generally to reduce the potential dilution to the Class A common shares and ADSs upon conversion of the Bond. The strike price of the Capped Call Transactions corresponds to the adjusted conversion price of the Bond and the cap price currently is $5.87 per ADS and has been adjusted under the terms of the Capped Call Transactions. The Capped Call Transactions will terminate upon the maturity date of the Bond and will be settled in net ADSs unless the Group elected the cash settlement method. The Group accounted for the capped call transactions as equity transactions and recorded the $22,885,000 purchase price as a deduction of additional paid in capital.

The main terms of the Bond are summarized as follows:

Conversion

The Bond are convertible into the Company’s ADSs, at the option of the holders, in integral multiples of $1,000 principal amount, at any time prior to the close of business on the second scheduled trading day immediately preceding the maturity date. The conversion rate equals 229.1856 ADSs per $1,000 principal amount of the Bond, which represents the adjusted conversion price of $4.36 per ADS. During the years ended February 28, 2017 and February 28, 2018, certain bond holders converted their bonds with carrying amount of $4,501,000 and $214,424,000 to 1,027,386 and 49,142,340 ADSs, respectively. Fractional ADSs were settled in cash.

Redemption

The Company does not have the right to redeem the Bond prior to maturity except for certain circumstances involving changes in the tax laws for the relevant tax jurisdiction. Holders of the Bond have the right to require the Company to repurchase in cash all or part of their Bond on May 15, 2017 or upon the occurrence of certain fundamental changes at a repurchase price equal to 100% of the principal amount of the Bond to be repurchased, plus any accrued and unpaid interest to, but excluding, the repurchase date.

Surrender a portion of Series C convertible redeemable preferred shares to Changing in exchange for the Guangzhou Tutoring, which was previously disposed in fiscal year 2016. Please refer to Note 3 and Note 15 for details.

Purchase a portion of Series C convertible redeemable preferred shares of Changing with total cash consideration of $17,861,744, of which $12,171,744 was paid in fiscal year 2017.

The above three transactions were discrete and separately accounted for. In fiscal year 2018, the Group acquired minority equity interests in Changing by purchasing its Series D convertible redeemable preferred shares with a total cash consideration of $15,000,000.

There was an increase of $743,478 and $1,321,739 change in fair value of those investments in fiscal years 2017 and 2018, respectively. The Group recorded $1,564,200, $6,047,689 and $1,803,607 impairment loss during the years ended February 29, 2016, February 28, 2017 and February 28, 2018, respectively.

Assets and liabilities measured at fair value on a nonrecurring basis

The Group's goodwill and intangible assets are primarily acquired through business acquisitions. Purchase price allocation are measured at fair value on a nonrecurring basis as of the acquisition dates. The Group measures its goodwill and intangible assets at fair value on a nonrecurring basis annually or whenever events or changes in circumstances indicate that carrying amount of a reporting unit exceeds its fair value. Acquired intangible assets are measured using the 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 recognized impairment loss related to goodwill and acquired intangible assets arising from acquisitions of $nil, $nil and $357,762 for the years ended February 29, 2016, February 28, 2017 and February 28, 2018, respectively.

The Group measures long-term investments (excluding the available-for-sale investments and fair value option investments) at fair value on a nonrecurring basis whenever events or changes in circumstances indicate that the carrying value may no longer be recoverable. Please see Note 9(10) and Note 9(12) for details.

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.

The fair value of the bond payable was disclosed in Note 12.

TAL Hong Kong, Yidu Hong Kong and Firstleap Hong Kong were established in Hong Kong and are subject to Hong Kong Profits Tax on its activities conducted in Hong Kong. It is subject to Hong Kong profit tax at 16.5%. No provision for Hong Kong Profits tax has been made in the consolidated financial statements as it has no assessable income for the years ended February 29, 2016, February 28, 2017 and February 28, 2018.

PRC

Effective from January 1, 2008, a new Enterprise Income Tax Law, or (“the New EIT Law”), combined the previous income tax laws for foreign invested and domestic invested enterprises in the PRC by the adoption of a unified tax rate of 25% for most enterprises with the following exceptions.

Certain qualified high and new technology enterprises that meet the definition of “high and new technology enterprise strongly supported by the state” (“HNTE”) could benefit from a preferential tax rate of 15%. Xueersi Education was qualified as a HNTE and was subject to an enterprise income tax (“EIT”) rate of 15% from calendar years 2012 through 2016. Xueersi Education applied an EIT rate of 25% since calendar year 2017.

TAL Beijing was qualified as a HNTE and was accordingly entitled to a preferential tax rate of 15% from calendar years 2014 through 2019 and is expected to be subject to an EIT rate of 15% as long as it maintains its status as an HNTE.

Yidu Huida was qualified as a HNTE and was accordingly entitled to a preferential tax rate of 15% from calendar years 2015 through 2017 and is expected to be subject to an EIT rate of 15% as long as it maintains its status as an HNTE. Yidu Huida applied for Key Software Enterprise status for calendar year 2016 and was approved in May 2017 which entitled Yidu Huida at the preferential tax rate of 10%. It applied 10% for calendar year 2016 and 15% for calendar year 2017.

Beijing Xintang Sichuang was qualified as “Newly Established Software Enterprise” in calendar year 2013 and therefore it was entitled to a two-year exemption from EIT and a further reduction to 12.5% from calendar years 2015 through 2017. It applied and was qualified as a HNTE and was subject to an EIT rate of 15% from calendar years 2017 through 2019. Beijing Xintang Sichuang applied an EIT of 12.5% for calendar year 2017.

Beijing Yinghe Youshi Technology Co., Ltd. ("Yinghe Youshi") was also qualified as HNTE and was accordingly entitled to a preferential tax rate of 15% from calendar years 2016 through 2018. It is expected to be subject to an EIT rate of 15% as long as it maintains its status as an HNTE.

Yizhen Xuesi was qualified as “Newly Established Software Enterprise” in calendar year 2017 and therefore it was entitled to a two-year exemption from EIT and a further reduction to 12.5% from calendar years 2019 through 2021.

Provision (credit) for income tax consisted of the following:

	For the year ended		For the year ended		For the year ended
	February 29,		February 28,		February 28,
	2016		2017		2018

Current
- PRC income tax expenses	$	34,474,418	$	37,720,637	$	48,958,623
Deferred
- PRC income tax expenses		(991,674)		(3,654,948)		(4,304,898)
Total	$	33,482,744	$	34,065,689	$	44,653,725

Deferred income taxes reflect the net tax effects of temporary differences between the carrying amount of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Significant components of the Group's deferred tax assets and liabilities were as follows:

	As of		As of
	February 28,		February 28,
	2017		2018
Non-current deferred tax assets:
Prepaid rental		1,694,073		2,386,560
Property and equipment		591,917		657,593
Impairment loss on long-term investments		2,098,309		553,229

Tax losses carry-forward		27,830,452		38,248,065

Non-current deferred tax assets, net	$	16,188,301	$	17,361,013

Non-current deferred tax liabilities:
Accrued ADR income		34,500		-
Intangible assets		5,959,102		5,342,969
Property and equipment		852,719		274,524
Long-term investments		6,339,565		14,421,547
Non-current deferred tax liabilities	$	13,185,886	$	20,039,040

As of February 28, 2018, tax loss carry-forward amounted to $159,878,732 and would expire by the end of calendar year 2023. The Company operates its business through its subsidiaries, its VIEs and VIEs' subsidiaries and schools. The Group does not file combined or consolidated tax returns, therefore, losses from individual subsidiaries or the VIEs and their subsidiaries and schools may not be used to offset other subsidiaries' or VIEs' earnings within the Group. Valuation allowance is considered on each individual subsidiary and VIE basis. A valuation allowance of $24,550,491 had been established as of February 28, 2018, in respect of certain deferred tax assets as it is considered more likely than not that the relevant deferred tax assets will not be realized in the foreseeable future.

Under U.S. GAAP, a deferred tax liability should be recorded for taxable temporary differences attributable to the excess of financial reporting amounts over tax basis amounts, including those differences attributable to a more than 50% interest in a domestic subsidiary. However, recognition is not required in situations where the tax law provides a means by which the reported amount of that investment can be recovered tax-free and the enterprise expects that it will ultimately use that means. The Company has not recorded any such deferred tax liability attributable to the undistributed earnings of its financial interest in VIEs because it believes such excess earnings can be distributed in a manner that would not be subject to income tax.

The impact of an uncertain income tax position on the income tax return is recognized at the largest amount that is more-likely-than-not to be sustained upon audit by the relevant tax authority. An uncertain income tax position will not be recognized if it has less than a 50% likelihood of being sustained. Interest and penalties on income taxes will be classified as a component of the provisions for income taxes. The Group has concluded that there are no significant uncertain tax positions requiring recognition in financial statements for the years ended February 29, 2016, February 28, 2017 and February 28, 2018. 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 12 months. The Group has no material unrecognized tax benefits which would favorably affect the effective income tax rate in future years.

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 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 is subject to examination by the PRC tax authorities based on the above.

Reconciliation between the provision for income taxes computed by applying the PRC EIT rates of 25% in fiscal year 2016, 2017 and 2018 to income before provision for income tax and the actual provision for income tax was as follows:

	For the year ended		For the year ended		For the year ended
	February 29,		February 28,		February 28,
	2016		2017		2018

Income before provision for income tax	$	136,902,200	$	154,580,964	$	246,993,826
PRC statutory income tax rate		25%		25%		25%
Income tax at statutory income tax rate		34,225,550		38,645,241		61,748,457
Effect of non-deductible and super deduction expenses		1,331,053		1,853,002		(2,244,191)
Effect of income tax exemptions and preferential tax rates		(12,830,838)		(26,256,983)		(37,390,108)
Effect of income tax rate difference in other jurisdictions		10,159,093		16,575,113		14,949,433
Change in valuation allowance		597,886		3,249,316		7,590,134
Provision for income tax	$	33,482,744	$	34,065,689	$	44,653,725

If Xueersi Education, Yidu Huida, TAL Beijing, Beijing Xintang Sichuang, Yinghe Youshi and Yizhen Xuesi did not enjoy income tax exemptions and preferential tax rates for the years ended February 29, 2016, February 28, 2017 and February 28, 2018, the increase in income tax expenses and net income per share amounts would be as follows:

	For the year ended		For the year ended		For the year ended
	February 29,		February 28,		February 28,
	2016		2017		2018

Increase in income tax expenses	$	12,830,838	$	26,256,983	$	37,390,108
Net income per common share-basic	$	0.56	$	0.56	$	0.90
Net income per common share-diluted	$	0.53	$	0.52	$	0.82

New EIT Law includes a provision specifying that legal entities organized outside of the PRC will be considered residents for Chinese Income tax purposes if the place of effective management or control is within the PRC. The implementation rules to the New EIT Law provide that non-resident legal entities will be considered PRC residents if substantial and overall management and control over the manufacturing and business operations, personnel, accounting, properties, etc, occurs within the PRC. Despite the present uncertainties resulting from the limited PRC tax guidance on the issue, the Group does not believe that the legal entities organized outside of the PRC within the Group should be treated as residents for EIT law purposes. If the PRC tax authorities subsequently determine that the Company and its subsidiaries registered outside the PRC should be deemed a resident enterprise, the Company and its subsidiaries registered outside the PRC will be subject to the PRC income tax at a rate of 25% with the statute subject to the determination by PRC tax authorities.

If the Company were to be non-resident for PRC tax purpose, 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 subsidiaries, the withholding tax would be 10%.

The Chinese tax authorities clarified that distributions made out of earnings prior to but distributed after January 1, 2008 will not be subject to withholding tax. The aggregate undistributed earnings of the Company's subsidiaries, VIEs and VIEs' subsidiaries and schools located in the PRC that are available for distribution are $556,236,815 and $925,484,106 as of February 28, 2017 and February 28, 2018, respectively. Upon distribution of such earnings, the Company will be subject to PRC taxes, the amount of which is impractical to estimate. The Company did not record any withholding tax on any of the aforementioned undistributed earnings because it intends to permanently reinvest all earnings in China and the aforementioned subsidiaries do not intend to declare dividends to the Company.

STATUTORY RESERVES AND RESTRICTED NET ASSETS

As stipulated by the relevant PRC laws and regulations, PRC entities are required to make appropriations from net income as determined in accordance with the PRC GAAP to non-distributable statutory reserve, which includes a statutory surplus reserve and a statutory welfare reserve (the “reserve fund”), and a development fund. The PRC laws and regulations require that annual appropriations of 10% of after-tax income should be set aside prior to payments of dividends as statutory surplus reserve until the balance reaches 50% of the PRC entity registered capital.

In private school sector, the PRC laws and regulations require that certain amount should be set aside as development fund prior to payments of dividends. In the case of private school that requires reasonable returns, this amount should be no less than 25% of the annual net income of the school, while in the case of a private school that does not require reasonable returns, this amount should be no less than 25% of annual increase in the net assets of the school, if any.

The statutory reserve may be applied against prior year losses, if any, and may be used for general business expansion and production or increase in registered capital of the entities. For the years ended February 28, 2017 and February 28, 2018, the Group made apportions of $877,924 and $476,296 to the statutory surplus reserve, respectively, and $4,547,597 and $9,431,776 to the development fund, respectively.

As a result of these PRC laws and regulations and the requirement that distribution by PRC entities can only be paid out of distributable profits computed in accordance with PRC GAAP, the PRC entities are restricted from transferring a portion of their net assets to the Group. Amounts restricted include paid-in capital and the statutory reserve of the Company's PRC subsidiaries, the VIEs and VIEs' subsidiaries and schools. As of February 28, 2017 and February 28, 2018, paid-in capital balance of such entities was $53,638,081 and $80,888,341, respectively, and statutory reserve balance was $28,407,421 and $38,315,493, respectively. The total of restricted net assets as of February 28, 2017 and February 28, 2018 was therefore $82,045,502 and $119,203,834, respectively.

SHARE-BASED COMPENSATION

In June 2010, the Company adopted the 2010 Share Incentive Plan. The plans permit the grant of options to purchase the Class A common shares, share appreciation rights, restricted shares, restricted share units, dividend equivalent rights and other instruments as deemed appropriate by the administrator under the plans. In August 2013, the Company amended and restated the 2010 Share Incentive Plan. Pursuant to the amended and restated 2010 Share Incentive Plan, the maximum aggregate number of Class A common shares that may be issued pursuant to all awards under the share incentive plan is equal to five percent (5%) of the total issued and outstanding shares as of the date of the amended and restated 2010 Share Incentive Plan. However, the shares reserved may be increased automatically if and whenever the unissued share reserve accounts for less than one percent (1%) of the total then issued and outstanding shares, so that after the increase, the shares unissued and reserved under this plan immediately after each such increase shall equal five percent (5%) of the then issued and outstanding shares.

The total compensation expense is recognized on a straight-line basis over the respective vesting periods. The Group recorded the related compensation expense of $25,847,497, $36,115,200 and $47,149,738 for the years ended February 29, 2016, February 28, 2017 and February 28, 2018, respectively.

[1]	Please refer to Note 14(a) fair value option investments and available-for-sale investments for details.
[2]	The Group purchased wealth management products from financial institutions in China and classified them 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 was two years and recorded at amortized cost. The Group estimated that their fair value approximate their carrying amount.
[3]	In October 2014, the Group acquired minority equity interest in Minerva Project, Inc., a Delaware corporation that is committed to providing an exceptional and accessible liberal arts and sciences education for future leaders and innovators across all disciplines. The total consideration was $18,000,003. The Group applied cost method to account for the investment due to lack of ability to exercise significant influence and reviewed the investment for impairment whenever an event or circumstance indicates that an other-than-temporary impairment has occurred. As of February 28, 2018, no impairment loss has been recorded in regard to the investment.
[4]	In January 2016, the Group acquired minority equity interest in Knewton, Inc., a company in adaptive learning incorporated in Delaware with total cash consideration of $5,000,001. In March 2016, the Group acquired additional minority equity interest in Knewton, Inc. with total cash consideration of $6,582,166. The Group applied cost method to account for the investment due to lack of ability to exercise significant influence and reviewed the investment for impairment whenever an event or circumstance indicates that an other-than-temporary impairment has occurred. As of February 28, 2018, no impairment loss was recorded in regard to the investment.
[5]	The Group holds equity interests in several third-party private companies through investments in their common shares or in-substance common shares where these equity interests are generally less than 10%. The Group accounts for these investments under the cost method as the Group has no ability to exercise significant influence over the investees. The Group recorded $nil, $1,269,611 and $nil impairment loss during the fiscal years ended February 29, 2016, February 28, 2017 and February 28, 2018, respectively.
[6]	In December 2015, the Group invested $30,000,000 to acquire 32% equity interest of Phoenix E-Learning Corporation, which operates zxxk.com, an online educational platform serving the public school system in China. The Group has the ability to exercise significant influence but does not have control over the investee and used the equity method to account for the investment. The Group accounts for its investment in Phoenix E-Learning Corporation on a one quarter lag basis as the financial statements of this investee cannot be made available within a reasonable time.
[7]	In May 2016, the Group and two third-parties which are related parties (“third party group”), established Gongying Fund, a limited liability partnership focusing on investing in private education companies. The Group and the third party group owns 20% and 80% equity interest of Gongying Fund, respectively. They are co-general partners of Gongying Fund. Gongying Fund’s scale is RMB259.0 million (equivalent to $37.7 million) that the Group and the third party group have committed to invest RMB51.6 million (equivalent to $7.5 million) and RMB207.4 million (equivalent to $30.2 million), respectively. As of February 28, 2018, both parties have fulfilled half of their respective capital commitment to Gongying Fund. The Group and the third party committed to invest the remaining portion upon the capital call of Gongying Fund. All investment decisions made by Gongying Fund have to be approved by both parties. The Group has the ability to exercise significant influence but does not have control over Gongying Fund due to the other partner’s substantive participating rights, and thereby used the equity method to account for the investment. In fiscal year 2017, Gongying Fund invested RMB70 million (equivalent to $10.2 million) to purchase minority equity interests of two privately held education companies.
[8]	In September 2015, the Group acquired 20% equity interest in Shenzhen Youban, which is mainly engaged in the development of online early education mobile application.
