ORGANIZATION_AND_PRINCIPAL_ACT

ORGANIZATION AND PRINCIPAL ACTIVITIES	12 Months Ended
	Dec. 31, 2013
ORGANIZATION AND PRINCIPAL ACTIVITIES	'
	1	ORGANIZATION AND PRINCIPAL ACTIVITIES
	iSoftStone Holdings Limited (the “Company”), incorporated in the Cayman Islands, is the holding company for a group of companies. The Company, its subsidiaries and one consolidated variable interest entity (the “VIE”) (collectively the “Group”) are principally engaged in providing an integrated suite of IT services and solutions, including IT services, Consulting and Solution services, and Business Process Outsourcing services (“BPO services”).
	The Group commenced its operations in October 2001 through Beijing iSoftStone Technologies Limited (“Beijing iSoftStone”), a limited liability company established in China and owned by Mr. Tianwen Liu and other individuals (the “founders”).
	In November 2005, the corporate structure of the Group was reorganized by establishing the Company and transferring substantially all the operating assets and operations of Beijing iSoftStone into iSoftStone Information Technology (Group) Company Limited (“iSoftStone WFOE”), a wholly owned subsidiary of the Company, in exchange of issuance of ordinary shares of the Company to the founders.
	The ultimate beneficial shareholders of the Company and Beijing iSoftStone were identical with no shareholder having, before or after the reorganization, a controlling interest. The Company has therefore accounted for this transaction as a recapitalization with no change in the basis of the assets and liabilities of Beijing iSoftStone.
	Currently, the Group conducts its business primarily through the following subsidiaries:
		•		iSoftStone WFOE, which is a primary operating entity and hosts the Group’s headquarters in Beijing, China. iSoftStone WFOE operates China-based delivery platform and holds China-based subsidiaries, mainly including: iSoftStone Information Technology Co., Ltd. located in Tianjin, iSoftStone Information System Service Co., Ltd. located in Wuxi, and Guangzhou iSoftStone Information Technology Co., Ltd. located in Guangzhou and iSoftstone Technology Service Company Limited in Wuhan.
		•		iSoftStone Inc., the Company’s wholly owned subsidiary incorporated in the State of Delaware, United States.
		•		iSoftStone Japan Limited, the Company’s wholly owned subsidiary incorporated in Japan.
	The Group completed a number of acquisitions in the years presented:
		•		In January 2011, the Group acquired iHealthStone Co., Limited (“iHealthStone”).
		•		In July 2011, the Group acquired Adventier Consulting Group, Inc. (“Adventier”).
		•		In April 2012, the Group acquired the power distribution solution business of Nanjing Jiangchen Science & Technology Co., LTD. (“Jiangchen”).
		•		In June 2012, the Group acquired Abovenet International Inc. (“Abovenet”).
		•		In May 2013, the Group acquired Beijing Ruantong Xutian Technology Development Co., Ltd. (Ruantong Xutian).
		•		In August 2013, the Group acquired the real estate solution business of Beijing LDeasy Science & Technology Co., Ltd. (“LDeasy”).

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of presentation

The consolidated financial statements of the Group are prepared in accordance with 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, all its wholly owned and majority owned subsidiaries and the VIE in which the Group is deemed to be the primary beneficiary. All inter-company transactions and balances have been eliminated upon consolidation.

Variable interest entity

In June 2009, the Financial Accounting Standards Board (“FASB”) issued an authoritative pronouncement to amend the accounting rules for VIEs. The amendments effectively replace the quantitative-based risks-and-rewards calculation for determining which reporting entity, if any, has a controlling financial interest in a variable interest entity with an approach focused on identifying which reporting entity has (1) the power to direct the activities of a variable interest entity that most significantly affect the entity’s economic performance and (2) the obligation to absorb losses of, or the right to receive benefits from, the entity. Additionally, an enterprise is required to assess whether it has an implicit financial responsibility to ensure that a variable interest entity operates as designed when determining whether it has the power to direct the activities of the variable interest entity that most significantly impact the entity’s economic performance. The guidance also requires additional disclosures about a reporting entity’s involvement with variable interest entities and about any significant changes in risk exposure as a result of that involvement.

The VIE generated limited net revenues from providing services to primarily PRC state-owned entities which are not permitted to receive certain services from foreign owned entities such as the Company and iSoftStone WFOE.

Use of estimates

The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, revenue and expenses in the financial statements and accompanying notes. Actual results could differ from those estimates. Significant accounting estimates reflected in the Group’s consolidated financial statements include, but are not limited to, revenue recognition, income taxes, collectability of accounts receivable, impairment of goodwill, estimated useful lives and impairment of property and equipment and intangible assets, contingent consideration in relation to business combinations and share-based compensation.

Cash and cash equivalents

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

Restricted cash

Restricted cash represents the security deposits with certain Chinese banks who issue bank accepted drafts for the purpose of settlement of trading purchases with the Company’s suppliers. The restriction normally lasts for a period of three to six months.

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 asset or liability such as quoted prices for similar assets or liabilities in active markets; quoted prices for identical assets or liabilities in markets with insufficient volume or infrequent transactions (less active markets); or model-derived valuations in which significant inputs are observable or can be derived principally from, or corroborated by, observable market data.

Level 3

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

Financial instruments

The Group’s financial instruments mainly include cash and cash equivalents, restricted cash, accounts receivable, accounts payable, amounts due from/and to related parties, short term borrowings, long term borrowings, long term investments, contingent consideration payable in connection with business acquisitions, and convertible notes.

The carrying values of cash and cash equivalent, restricted cash, accounts receivable, accounts payable, and amounts due from/and to related parties approximate their fair values due to short-term maturities.

The carrying amounts of short term and long term borrowings approximate their fair values as the borrowings bear variable interest rates which approximate the market interest rate.

Estimate of fair value of cost of equity method investments are not readily available.

Contingent consideration payable in connection with business acquisitions and return rate reset and conversion right derivatives embedded in the convertible notes were carried at fair value.

Allowance for doubtful accounts

Accounts receivable represents those receivables derived in the ordinary course of business. The Group conducts credit evaluations of clients and generally do not require collateral or other security from their clients. The Group establishes an allowance for doubtful accounts based upon estimates, historical experience and other factors surrounding the credit risk of specific clients.

Property and equipment, net

Property and equipment, net, are stated at cost less accumulated depreciation and amortization. Depreciation and amortization are provided using the straight-line method over the following estimated useful lives:

Building

45 - 48 years

Computers and software

3 - 5 years

Furniture and office equipment

5 - 17 years

Motor vehicles

5 years

Leasehold improvements

the shorter of lease terms or the estimated useful lives

Depreciation and amortization of these assets, on the same basis as other property assets, commences when the assets are ready for their intended use.

Land use right

All land in the PRC is owned by the PRC government, which, according to the relevant PRC law, may grant the right to use the land for a specified period of time. Payment for acquiring land use right is stated at cost less accumulated amortization and any recognized impairment loss. Amortization is provided on a straight-line basis over the term of the land use right.

Long term investments

Investee companies over which the Group has the ability to exercise significant influence, but does not have a controlling interest are accounted for using the equity method. Significant influence is generally considered to exist when the Group has an ownership interest in the voting shares of the investee between 20% and 50%, and other factors, such as representation in the investee’s Board of Directors, voting rights and the impact of commercial arrangements, are considered in determining whether the equity method of accounting is appropriate.

Investee companies over which the Group has no ability to exercise significant influence, nor has a controlling interest are accounted for using the cost method. No significant influence is generally considered to exist when the Group has an ownership interest in the voting stock of the investee less than 20% are considered in determining whether the cost method of accounting is appropriate.

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.

Business combination

Business combinations are recorded using the purchase method of accounting.

The assets acquired, the liabilities assumed, and any noncontrolling interest of the acquiree at the acquisition date, if any, are measured at their fair values as of that 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, 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 at the date of acquisition. For shares issued in a business combination, the Group had estimated the fair value as of the date of acquisition based on the closing market price of the shares of the company.

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.

Acquired intangible assets with finite lives

The Group measured the fair value of the purchased intangible assets arising from acquisitions using the “cost”, “income approach-excess earnings” and “with & without” valuation method. In performing the purchase price allocation, the Group considered, among other factors, forecast financial performance of the acquired business, market performance, and the market potential of the acquired business. These purchased intangible assets and contingent consideration are considered Level 3 assets and liabilities because the Group used unobservable inputs, reflecting the Group’s assessment of the assumptions market participants would use in valuing these assets and liabilities.

Customer base and part of software copyright is amortized using the estimated attrition pattern of the acquired intangible assets. The weighted average amortization period in total is 4.5 years. Contract backlog, non-compete agreements, trademark, software copyright, core technology and product technology are amortized using the straight-line method over the following estimated economic lives:

Customer base

1.8 - 6 years

Contract backlog

0.3 - 1.3 years

Non-compete agreements

3 - 5 years

Trademark

4.4 years

Software copyright

1 - 5 years

Core technology

6 years

Product technology

5 years

Impairment of long-lived assets with finite lives

The Group evaluates its long-lived assets or asset group including intangibles with definite lives for impairment whenever events or changes in circumstances (such as a significant adverse change to market conditions that will impact the future use of the assets) indicate that the carrying amount of a group of long-lived assets may not be fully recoverable. When these events occur, the Group evaluates the impairment by comparing the carrying amount of the assets to future undiscounted net cash flows expected to result from the use of the assets and their eventual disposition. If the sum of the expected undiscounted cash flows is less than the carrying amount of the assets, the Group recognizes an impairment loss based on the excess of the carrying amount of the asset group over its fair value, generally based upon discounted cash flows.

There were no impairment losses during the years ended December 31, 2011, 2012 and 2013.

Goodwill and impairment of goodwill

The excess of the purchase price over the fair value of net assets acquired is recorded on the consolidated balance sheet as goodwill. Goodwill is not amortized but is tested for impairment at the reporting unit level on an annual basis and between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying value. These events or circumstances could include a significant change in the stock prices, business climate, legal factors, operating performance indicators, competition, or sale or disposition of a significant portion of a reporting unit.

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

In September 2011, the FASB issued an authoritative pronouncement related to testing goodwill for impairment. The guidance permits to first assess qualitative factors to determine whether it is “more likely than not” that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step goodwill impairment test. The Group adopted this pronouncement in 2012. If it is more likely than not that the fair value of a reporting unit is less than its carrying amount, goodwill is then tested following a two-step process. The first step compares the fair value of each reporting unit to its carrying amount, including goodwill. If the fair value of each reporting unit exceeds its carrying amount, goodwill is not considered to be impaired and the second step will not be required. If the carrying amount of a reporting unit exceeds its fair value, the second step compares the implied fair value of goodwill to the carrying value of a reporting unit’s goodwill. The implied fair value of goodwill is determined in a manner similar to accounting for a business combination with the allocation of the assessed fair value determined in the first step to the assets and liabilities of the reporting unit. The excess of the fair value of the reporting unit over the amounts assigned to the assets and liabilities is the implied fair value of goodwill. An impairment loss is recognized for any excess in the carrying value of goodwill over the implied fair value of goodwill. The Group recognized no impairment loss on goodwill in 2011, 2012 and 2013.

Research and development expenses

Research and development costs are expensed as incurred unless technical and commercial feasibility of the project is demonstrated, future economic benefits are probable. To date, costs incurred after technological feasibility was established and prior to completion of software development have not been material, and accordingly, the Group has expensed all research and development expenses when incurred.

Revenue recognition

The Group provides a comprehensive range of IT services and solutions, categorized into three business lines: (i) IT services; (ii) Consulting and Solution services; and (iii) BPO services. The rights to software developed by the Group on behalf of its clients belong to the clients and the Group does not have the option to acquire such rights from its clients. The Group provided services on a time-and-expense basis, fixed-price basis or, with respect to some BPO services, on a volume basis.

Revenue is considered realizable and earned when all of the following criteria are met: persuasive evidence of a sales arrangement exists; delivery has occurred or services have been rendered; the price is fixed or determinable; and collectability is reasonably assured.

Time-and-expense basis contracts

Revenues from time-and-expense basis contracts are recognized as the related services are rendered assuming all other basic revenue recognition criteria are met. Under time-and-expense basis contracts, the Group is reimbursed for actual hours incurred at pre-agreed negotiated hourly billing rates. Clients may terminate the contracts at any time before the work is completed but are obligated to pay the actual service hours incurred through the termination date at the contract billing rate. Net revenues recognized for time-and-expense basis contracts totaled $107,261, $142,474 and $160,884 for the years ended December 31, 2011, 2012 and 2013, respectively.

Fixed-price basis contracts

Revenues from fixed-price basis contracts require the Group to perform services throughout the contractual period, which are generally less than two years. Revenues from this type of arrangements are generally recognized using the proportional performance method based on the proportion of direct labor costs incurred to the budgeted direct labor costs. The Group recognizes cost of revenues for labor and other costs on actual basis with no deferral of project costs. The Group believes it can reasonably estimate the service hours expected to be incurred on each project and there is no retention provisions based on the Group’s historic experience. To date, the Group has not incurred a material loss on any contracts. However, as a policy, provisions for estimated losses on such engagements will be made during the period in which a loss becomes probable and can be reasonably estimated. Service fee received in excess of revenues recognized are recorded as deferred revenues.

Net revenues recognized for fixed-price basis contracts totaled $172,695, $235,877 and $277,118 for the years ended December 31, 2011, 2012 and 2013, respectively.

Volume basis contracts

For volume basis contracts, the Group recognizes service revenues based on the volume of the transactions processed for the clients and a pre-agreed unit price for each type of process. Net revenues recognized for volume basis contracts totaled $3,461, $2,793 and $6,193 for the years ended December 31, 2011, 2012 and 2013, respectively.

Business tax and value added taxes

Before VAT pilot program, the Group’s PRC subsidiaries were subject to business tax at rate of 5% and related surcharges of total revenues for certain type of contracts. Certain services contracts are exempted from business tax in accordance with the PRC tax laws. Business tax is recorded as a reduction in revenues when incurred.

In November 2011, the Ministry of Finance and the State Administration of Taxation jointly issued circulars No. 110 and No. 111 regarding the pilot collection of VAT in lieu of business tax in certain industries in Shanghai. In July 2012, China’s State Council that the VAT reform pilot program in Shanghai will be expanded to eight provinces/cities. The Ministry of Finance and the State Administration of Taxation jointly issued a circular No. 71 in July 2012 that formally sets out the timetable for, and scope of, the expanded program. Such VAT pilot program was phased in Beijing, Jiangsu, Anhui, Fujian, Guangdong, Tianjin, Zhejiang, and Hubei between September and December 2012. In August 2013, this tax pilot program has been extended to the remaining areas within China. As a result, from August 1, 2013 the Company’s PRC subsidiaries are subject to VAT at the rate of 6% on certain service revenues which were previously subject to business tax.

Value added taxes rebate revenues

The Group receives value added taxes (“VAT”) rebates from tax authority as an incentive to encourage certain high-tech industries. The Group pays the relevant VAT and properly files the rebate application to tax authority and VAT rebates are recorded as revenue when the related rebates become receivable. The Group recorded $77, $16 and $198 of VAT rebate in revenue for the years ended December 31, 2011, 2012 and 2013, respectively. The VAT rebate revenues are classified into the relevant revenue categories.

Government subsidies

Government subsidies include amounts granted by local government authorities to encourage the employment of new college graduates and other purposes. Government subsidies are recorded as receivables when the approval is obtained from the local government authorities and the Group has the right to receive the subsidies, when historically the expenses that the subsidies intended to compensate normally have incurred by the Company. Subsidies to encourage employment of new college graduates are recognized in the statement of operations as deductions to the cost of revenues and related expenses, primarily costs of revenues. Subsidies for other purposes are recognized as other operating income because the subsidies are not intended to compensate for specific expenditure. For the years ended December 31, 2011, 2012 and 2013, the Group recognized government subsidies as a reduction to costs of revenues of $9,277, $13,845 and $11,019, respectively, as a reduction to operating expenses of $3,054, $3,192 and $1,594, respectively, and as other operating income of $1,840, $1,110 and $1,175, respectively.

Operating leases

Leases where substantially all the rewards and risks of ownership of assets remain with the lessor are accounted for as operating lease. Payments made under operating leases are charged to the consolidated statements of operations on a straight-line basis over the lease periods.

Advertising costs

Advertising costs are expensed as incurred and such expenses were minimal for the periods presented. Advertising costs have been included as part of selling and marketing expenses.

Income taxes

Current income taxes are provided for in accordance with the laws of the relevant tax authorities. Deferred income taxes are recognized for temporary differences between the tax bases of assets and liabilities and their reported amounts in the financial statements. Net operating loss carry forwards and credits are applied using 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. The components of the deferred tax assets and liabilities are individually classified as current and non-current based on their characteristics.

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 are classified as a component of the provisions for income taxes.

Foreign currency translation

The functional and reporting currency of the Company is the United States dollar (“U.S. dollar”). The financial records of the Group’s subsidiaries and VIE located in the PRC, Japan, Hong Kong, Taiwan, Korea, Canada, Germany and the United States are maintained in their local currencies, the Renminbi (“RMB”), Japanese Yen (“Yen”), Hong Kong Dollars (“HK$”), Taiwan Dollars (“NT$”), Korea Won (“WON”), Canadian Dollars (“CAD”), Euro (“EUR”) and U.S. Dollars (“US$”), respectively, which are also the functional currencies of these entities.

Monetary assets and liabilities denominated in currencies other than the functional currency are translated into the functional currency at the prevailing rates of exchange on the balance sheet date. Transactions in currencies other than the functional currency during the year are converted into functional currency at the applicable rates of exchange prevailing when the transactions occurred. Transaction gains and losses are recognized in the statements of operations.

The Group’s entities with functional currency of RMB, Yen, HK$, NT$, WON, CAD and EUR translate their operating results and financial position into the U.S. dollar, the Group’s reporting currency, based on the exchange rates quoted by the Federal Reserve Bank of New York. Assets and liabilities are translated using the exchange rates in effect on the balance sheet date. Revenues, expenses, gains and losses are translated using the average rate for the year. Translation adjustments are report as cumulative translation adjustments and are shown as a separate component of the other comprehensive income.

Comprehensive income

Comprehensive income is defined as the change in equity of a business enterprise during a period from transactions and other events and circumstances from non-owner sources and is presented in the Consolidated Statements of Comprehensive Income. Accumulated other comprehensive income (net of tax) at fiscal 2012 and 2013 year-ends are substantially comprised of accumulated foreign currency translation adjustments.

Share-based compensation

The Group grants share options to its employees for retention and incentive purposes. The value of the share options is measured based on the fair value on the grant date. The Group recognizes compensation costs, net of a forfeiture rate, on a straight-line basis over the requisite service period, which is generally the vesting period of the award in accordance with the graded vesting schedule. The amount of compensation expenses recognized for any period is not less than the portion of the fair value of the options vested during that period. The estimate of forfeiture rate is adjusted over the requisite service period to the extent that actual forfeiture rate differs, or are expected to differ, from such estimates. Changes in estimated forfeiture rate are recognized through a cumulative true-up adjustment in the period of change and will impact the amount of share-based compensation expense to be recognized in future periods.

Shares awards issued to non-employees, such as consultants, are measured at fair value at the earlier of the commitment date or the date the service is completed, and are recognized over the period the service is provided in accordance with the graded vesting schedule.

Net income per share

Basic net income per ordinary share is computed by dividing net income attributable to ordinary shareholders by the weighted average number of ordinary shares outstanding during the period.

Diluted net income per ordinary share reflects the potential dilution that could occur if securities or other contracts to issue ordinary shares were exercised or converted into ordinary shares.

The Group’s nonvested shares were participating securities, as certain nonvested shares were entitled to dividend right before vesting. Accordingly, the Group used the two-class method whereby undistributed net income was allocated on a pro rata basis to the ordinary, and certain nonvested shares to the extent that each class might share income for the period, whereas the undistributed net loss was allocated to ordinary shares and certain nonvested shares.

In periods where losses are reported, the weighted-average number of common shares outstanding excludes common stock equivalents, because their inclusion would be anti-dilutive.

Significant risks and uncertainties

Foreign currency risk

RMB is not freely convertible into other currencies. All foreign exchange transactions involving RMB must take place through the People’s Bank of China or other institutions authorized to buy and sell foreign currency. The exchange rate adopted for the foreign exchange transactions are the rates of exchange quoted by the Federal Reserve Bank of New York that are determined largely by supply and demand. The Group’s cash balances in RMB as of December 31, 2011, 2012 and 2013 were RMB473, 192,669, RMB531,962,381 and RMB478,731,600 respectively.

During the periods, the Group incurred foreign currency risk mainly on sales denominated in US$, and Japanese Yen. The Group did not enter into any foreign exchange forward contracts to hedge against exchange rate fluctuations.

Concentration of credit risk

Financial instruments that potentially expose the Group to concentration of credit risk consist primarily of cash and cash equivalents, restricted cash, and accounts receivable.

The Group places the majority of its cash and cash equivalents and restricted cash with financial institutions located in the PRC and the United States of America. The Group conducts credit evaluations of customers and generally do not require collateral or other security from their customers.

The Group has relatively high concentration of revenues with certain clients. Client accounting for 10% or more of total net revenues is as follows:

Billing requirements vary by contract, but are generally structured around completion of certain implementation milestones or the completion of the project.
	As of December 31, 2012 and 2013, billed accounts receivable with a carrying value of $10,919 and $11,238 respectively were pledged as collateral, for short term bank loans. The bank loans will expire at June 24, 2014.

	The Group performed its annual goodwill impairment tests for the years ended December 31, 2011, 2012 and 2013. In the goodwill impairment test, the Group used the income approach, which it believed to be more reliable than the market approach in determining the fair value of the Group’s reporting unit. Accordingly, it adopted a discounted cashflow (“DCF”) method under the income approach, which considered a number of factors that include expected future cash flows, growth rates and discount rates and requires the Group to make certain assumptions and estimates regarding industry economic factors and future profitability of its business unit. The assumptions were inherently uncertain and subjective.
	When applying the DCF method for the reporting unit, the Group incorporated the use of projected financial information and a discount rate that was developed using market participant based assumptions. The cash flow projections were based on six-year financial forecasts developed by management that included revenue projections, capital spending trends, and investments in working capital to support anticipated revenue growth. The discount rates selected were 13%, 14% and 15.5% for China, Japan and U.S. respectively with the consideration of the risk and nature of the reporting unit’s cash flows and the rates of return market participants would require investing their capital in the reporting unit.
	The Group evaluated the situation as of December 31, 2012 and 2013 based on the performance results and future operation projections with the assistance of American Appraisal China Limited, an independent valuation firm. Based on impairment test performed, no impairment of goodwill was recorded during the years ended December 31, 2011, 2012 and 2013, respectively.

	The Group’s PRC entities are subject to the Enterprise Income Tax (“EIT”) Law effective on January 1, 2008 which adopted a uniform EIT rate of 25% for all PRC enterprises including foreign-invested enterprises. Under the law, an enterprise qualified as a high and new technology enterprise (“HNTE”) is entitled to a preferential income tax rate of 15%.
	Various entities of the Group enjoyed certain preferential tax rates as follows:
	iSoftStone WFOE was qualified as HNTE in 2008 and entitled to a three-year exemption starting from 2006 to 2008 followed by a reduced income tax rate of 7.5% for the subsequent three years from 2009 to 2011. iSoftStone WFOE has renewed its qualification certificate of HNTE in 2011 and is eligible to an income tax rate of 15% for the next three years from 2012. The Group believes it is highly likely that its qualifying entities will continue to obtain the renewal in the future. Accordingly, in calculating deferred tax assets and liabilities, the Group has assumed its qualifying entities will continue to renew the HNTE status. If the Group’s qualifying entities failed to obtain such renewals, then the net deferred tax assets balance would increase by $1,190 as of December 31, 2013, which would be an increase to the income tax benefit.

The Group did not identify significant unrecognized tax benefits for years ended December 31, 2011, 2012 and 2013. The Group did not incur any interest and penalties related to potential underpaid income tax expenses and also believed that the adoption of pronouncement issued by FASB regarding accounting for uncertainty in income taxes did not have a significant impact on the unrecognized tax benefits within the next 12 months from December 31, 2013.
Since January 1, 2007, the relevant tax authorities of the Group’s subsidiaries have not conducted a tax examination on the Group’s subsidiaries. In accordance with relevant PRC tax administration laws, tax years from 2007 to 2013 of the Group’s PRC subsidiaries and VIE remain subject to tax audits, at the tax authority’s discretion.
Uncertainties exist with respect to how the current income tax law in the PRC applies to the Group’s overall operations, and more specifically, with regard to tax residency status. The 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 China 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 resident enterprises, the Company and its subsidiaries registered outside the PRC will be subject to the PRC income taxes, at a rate of 25%.
If the Company were to be non-resident for the PRC tax purpose, dividends paid to it by its PRC subsidiaries out of profits earned after January 1, 2008 would be subject to a PRC withholding tax at 10%.
If any entity within the Group that is outside the PRC were to be a non-resident for PRC tax purposes dividends paid to it out of profits earned by PRC subsidiary after January 1, 2008 would be subject to a withholding tax at a rate of 10%, subject to reduction by an applicable tax treaty with the PRC. Aggregated undistributed earnings of the Company’s subsidiaries located in the PRC that are available for distribution was $98,037 as of December 31, 2013. The Company did not record any tax on any of the aforementioned undistributed earnings because the relevant subsidiaries do not intend to declare dividends and the Company intends to permanently reinvest it within the PRC.

	18	CONVERTIBLE NOTES
	On December 23, 2009, the Company issued Convertible Notes (the “Notes”) at the principal amount of $29,000. As of December 31, 2009, the Company received proceeds of $28,802 after deduction of $198 issuance cost. On April 21, 2010 and April 22, 2010, the Company issued additional Notes at the principal amount of $9,000 with an issuance cost of $367.
	The key terms of the Notes are summarized as follows:
	Maturity date
		•		Initial Maturity Date-December 23, 2012;
		•		Extended Maturity Date-In the event that no IPO or Company Sale (defined as transactions through which the equity holders of the Company will lose control of the Company or iSoftStone WFOE) has occurred prior to the Initial Maturity Date, a majority of the Notes holders may extend the maturity date to a date on or prior to December 23, 2015.
	Interest rate and interest payment
		•		Interest rate is at 1% per annum, due and payable in cash in arrears on each anniversary of December 23, 2009 until the earlier of (i) the Initial Maturity Date, (ii) the date these Notes are otherwise redeemed, or (iii) such date on which these Notes are converted in full.
		•		If the Initial Maturity Date of these notes is extended, these Notes bear no interest between the Initial Maturity Date and the Extended Maturity Date.
	Redemption and price
	The Company and Notes holders may redeem the Notes on the following basis:
		•		Redemption on maturity date by the Company: The Company shall redeem the outstanding principal amount of these Notes that has not been converted or redeemed on the Initial Maturity Date or the Extended Maturity Date, by payment of the redemption price that gives the Notes holders an annual return of 10% in cash. If the Initial Maturity Date or the Extended Maturity Date falls after the completion of an IPO, the Company shall redeem the outstanding principal amount as of the first anniversary following the completion of an IPO by payment of a price that gives the Notes holders an annual rate of return of 18% in cash plus any accrued and unpaid interest.
		•		Post-IPO redemption at the option of the Notes holders: At any time during twelve months following the completion of an IPO, the holders of these Notes shall have the right to require the Company to redeem for cash all of the total outstanding principal amount at a price that gives the Notes holders an annual rate of return of 18% plus any accrued and unpaid interest in priority to any payment on or with respect to the Company equity securities.
		•		Accelerated redemption upon default at option of the Notes holders: Upon the occurrence of an event of default as listed below, the Notes holders shall have the right to require the Company to redeem for cash all of the total outstanding principal amount of the Notes at a price equal to the then applicable redemption price:
	Events of default:
		(a)	Failure to pay principal or any other amount under these Notes when and as due;
		(b)	Breach of covenants, such as punctually paying the interest and principal according to the agreements, giving notice upon the events of default, and no dividend or redemption to the equity securities until earlier of IPO or full repayment of the Notes;
		(c)	Except as approved by the Board of Directors, any key managers sold his or her company equity securities at the Original Note Issuance Date;
		(d)	Either the founder, Mr. Tianwen Liu, or three out of the other seven key managers have ceased to perform management responsibilities; or
		(e)	Liquidation.
	Conversion and price
		•		Mandatory conversion upon Company Sale: Immediately prior to and subject to the completion of a Company Sale, all of the then outstanding principal amount of these Notes and the accrued and unpaid interest thereon shall be automatically converted into such number of ordinary shares at the conversion price set out below.
		•		Optional Conversion upon IPO: At any time during the 12 months after the completion of an IPO, the Notes holders of these Notes shall have the right to convert these Notes in whole, into such number of duly authorized, fully paid and non-assessable Ordinary Shares at the conversion price set out below.
		•		Conversion price is computed with following formula:
		•		Conversion Price =PO Price or Company Sale Price / ((1+ 0.082254247%) (number of days lapsed between the date of the Notes and the IPO or Company Sale date)) 0.082254247% is the daily compound rate based on a 365-day year that would result in an annual return of 35%.
		•		If the Company issues additional equity securities other than ordinary shares that are convertible into ordinary shares at a price based on a discount of the IPO price or Company Sale price where the Company guarantees the purchaser of such convertible equity securities at an annual return of more than 35%, the above compound rate used for calculating conversion rice shall be adjusted according to the higher rate of return.
		•		The conversion price has a standard anti-dilution adjustment term. It also has a down-round provision. If the Company, after the completion of an IPO, issues any additional ordinary shares or equity security at a price per share that is lower than the conversion price per share then in effect, then the conversion price per share is adjusted down.
	The return rate reset feature, which increases the redemption price of the Notes to give the Notes holders an annual rate of return of 18% rather than 10% if an IPO is completed before Initial Maturity Date or the Extended Maturity Date, were determined to be an embedded derivate and was bifurcated for measurement purposes and is presented on a combined basis with the Notes. The initial fair value of the embedded derivative was $1,706 as of December 23, 2009. And the fair value change from December 23, 2009 to December 31, 2009 was insignificant.
	The fair value of the embedded derivative of $1,706 as of December 23, 2009, determined with the assistance of American Appraisal China Limited, an independent valuation firm, and the issuance costs of $198 resulted in a debt discount of $1,904. The debt discount was amortized into interest expenses over the term of the Notes using effective interest method. For the year ended December 31, 2009, the Group incurred $63 interest expense relating to the Notes, of which $62 represented the amortization of the debt discount and $1 represented the coupon interest.
	Upon the issuance of additional Notes in April 2010, the initial embedded derivative attached to the second tranche of the Notes was $488 at the issuance date. Upon the Company’s IPO on December 14, 2010, the return rate of the Notes was reset to 18%, and accordingly, the fair value of the two tranches of embedded derivative totaled $8,904. A loss of $2,365 was recorded as the change in fair value of the return rate reset in the statement of operations for the year ended December 31, 2010.
	A debt discount of $2,759 was recorded to account for the initial fair value of the two tranches of the embedded derivate and the total issuance cost. The debt discount was amortized into interest expenses over the term of the Notes using effective interest method. For the year ended December 31, 2010, the Group incurred $4,418 interest expense relating to the Notes, of which $133 represented the amortization of the debt discount and $4,285 represented the coupon interest.
	In December 2010, Notes at the principal amount of $18,000 were converted into 18,381,991 ordinary shares upon the IPO of the Company. For the remaining Notes at the principal amount of $20,000, the Note holders have the right to convert it into ordinary shares during the twelve months after the completion of an IPO. As a consequence, when the shares were readily convertible into cash upon the completion of the IPO, the conversion right met the definition of a derivative which required to be bifurcated for measurement purposes. As of December 14, 2010, the fair values of the conversion right and the debt host for the remaining Notes of $20,000 were $2,841 and $17,159, respectively. As of December 31, 2010, the fair values of the conversion right and the debt host were $8,904 and $20,511, respectively. The fair value of the conversion right was determined by the Group with the assistance of American Appraisal, and the fair value change from December 14, 2010 to December 31, 2010 was $6,063, and recorded as a loss in the consolidated statement of operations for the year ended December 31, 2010.
	On March 3, 2011, Notes at the principal amount of $20,000 were converted into 20,406,720 ordinary shares. The fair value change from January 1, 2011 to March 3, 2011 was $2,832, and recorded as an income in the consolidated statement of operations for the year ended December 31, 2011. From January 1, 2011 to March 3, 2011, the Group incurred $654 interest expense relating to the Notes, of which $19 represented the amortization of the debt discount and $635 represented the coupon interest.

This was accounted for as a share option modification and required the remeasurement of the fair value of these share options. The remeasurement resulted in a total incremental share-based compensation of $1,381, of which $1,233 was recognized in the year ended December 31, 2013 and the remaining is to be recognized ratably over the remaining vesting period of the award.

12,078,146, 4,882,420 and 1,739,100 share options were exercised in 2011, 2012 and 2013 respectively. Total intrinsic value of options exercised in 2011, 2012 and 2013 was $12,369, $524 and $291 respectively, as the fair value of the options exercised exceeded its exercise price at the date of exercise.
The fair value of each option granted was estimated on the date of grant using the Black-Scholes option pricing model with the following assumptions used for grants during the applicable periods:
		For the year ended December 31,
		2012				2013
Risk-free interest rate of return			0.89	%		0.68%-0.92%
Expected term			6.1 years			6.1 years
Volatility			57.4	%		55%-57.1%
Dividend yield			—			—
(1) Volatility
The volatility of the underlying ordinary shares during the life of the options was estimated based on the historical stock price volatility of listed comparable companies over a period comparable to the expected term of the options.
(2) Risk-free interest rate
Risk-free interest rate was estimated based on the yield to maturity of China international government bonds with a maturity period close to the expected term of the options.
(3) Expected term
For the options granted to employees, it estimated the expected term based on a consideration of factors including contractual term and vesting period.
For the options granted to non-employees, the Company estimated the expected term as the original contractual term.
(4) Dividend yield
The dividend yield was estimated by the Group based on its expected dividend policy over the expected term of the options.
(5) Fair value of underlying ordinary shares
Before the IPO, the estimated fair value of the ordinary shares underlying the options as of the respective grant dates was determined based on a retrospective valuation. When estimating the fair value of the ordinary shares on the grant dates, management has considered a number of factors, including the result of a third-party appraisal by American Appraisal China Limited and equity transactions of the Company, while taking into account standard valuation methods and the achievement of certain events. The determination of fair value of the ordinary shares was also with the assistance of American Appraisal China Limited, an independent third party valuation specialist. After the IPO, the fair value of the ordinary shares is determined as the closing sales price of the shares.
For employee share options, the Group recorded share-based compensation of $4,778, $5,061 and $5,146 during the years ended December 31, 2011, 2012 and 2013, respectively, based on the fair value on the grant dates over the requisite service period of award using the straight-line method.

	Dispute with iCarnegie Inc. regarding certain licensing arrangements
	In 2009, in cooperation with the Wuxi City government, the Group established the iCarnegie-iSoftStone training center (currently owned 20% by the Group). Some programs provided at the iCarnegie-iSoftStone training center in 2009 utilized the technical curriculum and professional certifications developed and maintained by iCarnegie Inc. and licensed to us pursuant to course licensing arrangements first entered into in 2009. The Group had been negotiating with iCarnegie Inc. new cooperation arrangements, which were expected to replace existing licensing arrangements which include a minimum enrollment fee requirement. In October 2012, iCarnegie Inc. submitted a demand for arbitration to the American Arbitration Association. The arbitration hearing took place from March 31, 2014 through April 4, 2014. As of the arbitration date, iCarnegie was claiming approximately $11,084 (comprised of $5,889 in licensing fees that was allegedly due from the Group to iCarnegie Inc. pursuant to the course license agreement plus interest at a contractual rate of 18% per annum). As of December 31, 2013, the Group has not recorded a provision for this matter because the arbitration remains at its preliminary stage, the Group intends to vigorously defend the arbitration and the ultimate outcome of this arbitration cannot presently be determined.

FINANCIAL INFORMATION OF PARENT COMPANY
NOTES TO THE FINANCIAL STATEMENTS
1	BASIS FOR PREPARATION
The condensed financial information of the Company has been prepared using the same accounting policies as set out in the Group’s consolidated financial statement except that the Company used the equity method to account for investments in its subsidiaries and VIE.
2	INVESTMENTS IN SUBSIDIARIES
The Company and its subsidiaries and VIE were included in the consolidated financial statements where inter-company balances and transactions were eliminated upon consolidation. For purpose of the Company’s stand-alone financial statements, its investments in subsidiaries and VIE were reported using the equity method of accounting. The Company’s share of income and losses from its subsidiaries and VIE were reported as equity in earnings of subsidiaries and VIE in the accompanying parent company financial statements.

SUMMARY_OF_SIGNIFICANT_ACCOUNT1

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)

12 Months Ended

Dec. 31, 2013

Basis of Presentation

'

Basis of presentation

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

Basis of Consolidation

'

Basis of consolidation

The consolidated financial statements include the financial statements of the Company, all its wholly owned and majority owned subsidiaries and the VIE in which the Group is deemed to be the primary beneficiary. All inter-company transactions and balances have been eliminated upon consolidation.

Variable interest entity

'

Variable interest entity

In June 2009, the Financial Accounting Standards Board (“FASB”) issued an authoritative pronouncement to amend the accounting rules for VIEs. The amendments effectively replace the quantitative-based risks-and-rewards calculation for determining which reporting entity, if any, has a controlling financial interest in a variable interest entity with an approach focused on identifying which reporting entity has (1) the power to direct the activities of a variable interest entity that most significantly affect the entity’s economic performance and (2) the obligation to absorb losses of, or the right to receive benefits from, the entity. Additionally, an enterprise is required to assess whether it has an implicit financial responsibility to ensure that a variable interest entity operates as designed when determining whether it has the power to direct the activities of the variable interest entity that most significantly impact the entity’s economic performance. The guidance also requires additional disclosures about a reporting entity’s involvement with variable interest entities and about any significant changes in risk exposure as a result of that involvement.

The VIE generated limited net revenues from providing services to primarily PRC state-owned entities which are not permitted to receive certain services from foreign owned entities such as the Company and iSoftStone WFOE.

Use of Estimates

'

Use of estimates

The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, revenue and expenses in the financial statements and accompanying notes. Actual results could differ from those estimates. Significant accounting estimates reflected in the Group’s consolidated financial statements include, but are not limited to, revenue recognition, income taxes, collectability of accounts receivable, impairment of goodwill, estimated useful lives and impairment of property and equipment and intangible assets, contingent consideration in relation to business combinations and share-based compensation.

Cash and Cash Equivalents

'

Cash and cash equivalents

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

Restricted Cash

'

Restricted cash

Restricted cash represents the security deposits with certain Chinese banks who issue bank accepted drafts for the purpose of settlement of trading purchases with the Company’s suppliers. The restriction normally lasts for a period of three to six months.

Fair Value

'

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 asset or liability such as quoted prices for similar assets or liabilities in active markets; quoted prices for identical assets or liabilities in markets with insufficient volume or infrequent transactions (less active markets); or model-derived valuations in which significant inputs are observable or can be derived principally from, or corroborated by, observable market data.

Level 3

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

Financial Instruments

'

Financial instruments

The Group’s financial instruments mainly include cash and cash equivalents, restricted cash, accounts receivable, accounts payable, amounts due from/and to related parties, short term borrowings, long term borrowings, long term investments, contingent consideration payable in connection with business acquisitions, and convertible notes.

The carrying values of cash and cash equivalent, restricted cash, accounts receivable, accounts payable, and amounts due from/and to related parties approximate their fair values due to short-term maturities.

The carrying amounts of short term and long term borrowings approximate their fair values as the borrowings bear variable interest rates which approximate the market interest rate.

Estimate of fair value of cost of equity method investments are not readily available.

Contingent consideration payable in connection with business acquisitions and return rate reset and conversion right derivatives embedded in the convertible notes were carried at fair value.

Allowance for Doubtful Accounts

'

Allowance for doubtful accounts

Accounts receivable represents those receivables derived in the ordinary course of business. The Group conducts credit evaluations of clients and generally do not require collateral or other security from their clients. The Group establishes an allowance for doubtful accounts based upon estimates, historical experience and other factors surrounding the credit risk of specific clients.

Property and Equipment, Net

'

Property and equipment, net

Property and equipment, net, are stated at cost less accumulated depreciation and amortization. Depreciation and amortization are provided using the straight-line method over the following estimated useful lives:

Building

45 - 48 years

Computers and software

3 - 5 years

Furniture and office equipment

5 - 17 years

Motor vehicles

5 years

Leasehold improvements

the shorter of lease terms or the estimated useful lives

Depreciation and amortization of these assets, on the same basis as other property assets, commences when the assets are ready for their intended use.

Land Use Right

'

Land use right

All land in the PRC is owned by the PRC government, which, according to the relevant PRC law, may grant the right to use the land for a specified period of time. Payment for acquiring land use right is stated at cost less accumulated amortization and any recognized impairment loss. Amortization is provided on a straight-line basis over the term of the land use right.

Long Term Investments

'

Long term investments

Investee companies over which the Group has the ability to exercise significant influence, but does not have a controlling interest are accounted for using the equity method. Significant influence is generally considered to exist when the Group has an ownership interest in the voting shares of the investee between 20% and 50%, and other factors, such as representation in the investee’s Board of Directors, voting rights and the impact of commercial arrangements, are considered in determining whether the equity method of accounting is appropriate.

Investee companies over which the Group has no ability to exercise significant influence, nor has a controlling interest are accounted for using the cost method. No significant influence is generally considered to exist when the Group has an ownership interest in the voting stock of the investee less than 20% are considered in determining whether the cost method of accounting is appropriate.

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.

Business Combination

'

Business combination

Business combinations are recorded using the purchase method of accounting.

The assets acquired, the liabilities assumed, and any noncontrolling interest of the acquiree at the acquisition date, if any, are measured at their fair values as of that 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, 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 at the date of acquisition. For shares issued in a business combination, the Group had estimated the fair value as of the date of acquisition based on the closing market price of the shares of the company.

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.

Acquired Intangible Assets with Finite Lives

'

Acquired intangible assets with finite lives

The Group measured the fair value of the purchased intangible assets arising from acquisitions using the “cost”, “income approach-excess earnings” and “with & without” valuation method. In performing the purchase price allocation, the Group considered, among other factors, forecast financial performance of the acquired business, market performance, and the market potential of the acquired business. These purchased intangible assets and contingent consideration are considered Level 3 assets and liabilities because the Group used unobservable inputs, reflecting the Group’s assessment of the assumptions market participants would use in valuing these assets and liabilities.

Customer base and part of software copyright is amortized using the estimated attrition pattern of the acquired intangible assets. The weighted average amortization period in total is 4.5 years. Contract backlog, non-compete agreements, trademark, software copyright, core technology and product technology are amortized using the straight-line method over the following estimated economic lives:

Customer base

1.8 - 6 years

Contract backlog

0.3 - 1.3 years

Non-compete agreements

3 - 5 years

Trademark

4.4 years

Software copyright

1 - 5 years

Core technology

6 years

Product technology

5 years

Impairment of Long-lived Assets with Finite Lives

'

Impairment of long-lived assets with finite lives

The Group evaluates its long-lived assets or asset group including intangibles with definite lives for impairment whenever events or changes in circumstances (such as a significant adverse change to market conditions that will impact the future use of the assets) indicate that the carrying amount of a group of long-lived assets may not be fully recoverable. When these events occur, the Group evaluates the impairment by comparing the carrying amount of the assets to future undiscounted net cash flows expected to result from the use of the assets and their eventual disposition. If the sum of the expected undiscounted cash flows is less than the carrying amount of the assets, the Group recognizes an impairment loss based on the excess of the carrying amount of the asset group over its fair value, generally based upon discounted cash flows.

There were no impairment losses during the years ended December 31, 2011, 2012 and 2013.

Goodwill and Impairment of Goodwill

'

Goodwill and impairment of goodwill

The excess of the purchase price over the fair value of net assets acquired is recorded on the consolidated balance sheet as goodwill. Goodwill is not amortized but is tested for impairment at the reporting unit level on an annual basis and between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying value. These events or circumstances could include a significant change in the stock prices, business climate, legal factors, operating performance indicators, competition, or sale or disposition of a significant portion of a reporting unit.

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

In September 2011, the FASB issued an authoritative pronouncement related to testing goodwill for impairment. The guidance permits to first assess qualitative factors to determine whether it is “more likely than not” that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step goodwill impairment test. The Group adopted this pronouncement in 2012. If it is more likely than not that the fair value of a reporting unit is less than its carrying amount, goodwill is then tested following a two-step process. The first step compares the fair value of each reporting unit to its carrying amount, including goodwill. If the fair value of each reporting unit exceeds its carrying amount, goodwill is not considered to be impaired and the second step will not be required. If the carrying amount of a reporting unit exceeds its fair value, the second step compares the implied fair value of goodwill to the carrying value of a reporting unit’s goodwill. The implied fair value of goodwill is determined in a manner similar to accounting for a business combination with the allocation of the assessed fair value determined in the first step to the assets and liabilities of the reporting unit. The excess of the fair value of the reporting unit over the amounts assigned to the assets and liabilities is the implied fair value of goodwill. An impairment loss is recognized for any excess in the carrying value of goodwill over the implied fair value of goodwill. The Group recognized no impairment loss on goodwill in 2011, 2012 and 2013.

Research and Development Expenses

'

Research and development expenses

Research and development costs are expensed as incurred unless technical and commercial feasibility of the project is demonstrated, future economic benefits are probable. To date, costs incurred after technological feasibility was established and prior to completion of software development have not been material, and accordingly, the Group has expensed all research and development expenses when incurred.

Revenue Recognition

'

Revenue recognition

The Group provides a comprehensive range of IT services and solutions, categorized into three business lines: (i) IT services; (ii) Consulting and Solution services; and (iii) BPO services. The rights to software developed by the Group on behalf of its clients belong to the clients and the Group does not have the option to acquire such rights from its clients. The Group provided services on a time-and-expense basis, fixed-price basis or, with respect to some BPO services, on a volume basis.

Revenue is considered realizable and earned when all of the following criteria are met: persuasive evidence of a sales arrangement exists; delivery has occurred or services have been rendered; the price is fixed or determinable; and collectability is reasonably assured.

Time-and-expense basis contracts

Revenues from time-and-expense basis contracts are recognized as the related services are rendered assuming all other basic revenue recognition criteria are met. Under time-and-expense basis contracts, the Group is reimbursed for actual hours incurred at pre-agreed negotiated hourly billing rates. Clients may terminate the contracts at any time before the work is completed but are obligated to pay the actual service hours incurred through the termination date at the contract billing rate. Net revenues recognized for time-and-expense basis contracts totaled $107,261, $142,474 and $160,884 for the years ended December 31, 2011, 2012 and 2013, respectively.

Fixed-price basis contracts

Revenues from fixed-price basis contracts require the Group to perform services throughout the contractual period, which are generally less than two years. Revenues from this type of arrangements are generally recognized using the proportional performance method based on the proportion of direct labor costs incurred to the budgeted direct labor costs. The Group recognizes cost of revenues for labor and other costs on actual basis with no deferral of project costs. The Group believes it can reasonably estimate the service hours expected to be incurred on each project and there is no retention provisions based on the Group’s historic experience. To date, the Group has not incurred a material loss on any contracts. However, as a policy, provisions for estimated losses on such engagements will be made during the period in which a loss becomes probable and can be reasonably estimated. Service fee received in excess of revenues recognized are recorded as deferred revenues.

Net revenues recognized for fixed-price basis contracts totaled $172,695, $235,877 and $277,118 for the years ended December 31, 2011, 2012 and 2013, respectively.

Volume basis contracts

For volume basis contracts, the Group recognizes service revenues based on the volume of the transactions processed for the clients and a pre-agreed unit price for each type of process. Net revenues recognized for volume basis contracts totaled $3,461, $2,793 and $6,193 for the years ended December 31, 2011, 2012 and 2013, respectively.

Business tax and value added taxes

Before VAT pilot program, the Group’s PRC subsidiaries were subject to business tax at rate of 5% and related surcharges of total revenues for certain type of contracts. Certain services contracts are exempted from business tax in accordance with the PRC tax laws. Business tax is recorded as a reduction in revenues when incurred.

In November 2011, the Ministry of Finance and the State Administration of Taxation jointly issued circulars No. 110 and No. 111 regarding the pilot collection of VAT in lieu of business tax in certain industries in Shanghai. In July 2012, China’s State Council that the VAT reform pilot program in Shanghai will be expanded to eight provinces/cities. The Ministry of Finance and the State Administration of Taxation jointly issued a circular No. 71 in July 2012 that formally sets out the timetable for, and scope of, the expanded program. Such VAT pilot program was phased in Beijing, Jiangsu, Anhui, Fujian, Guangdong, Tianjin, Zhejiang, and Hubei between September and December 2012. In August 2013, this tax pilot program has been extended to the remaining areas within China. As a result, from August 1, 2013 the Company’s PRC subsidiaries are subject to VAT at the rate of 6% on certain service revenues which were previously subject to business tax.

Value added taxes rebate revenues

The Group receives value added taxes (“VAT”) rebates from tax authority as an incentive to encourage certain high-tech industries. The Group pays the relevant VAT and properly files the rebate application to tax authority and VAT rebates are recorded as revenue when the related rebates become receivable. The Group recorded $77, $16 and $198 of VAT rebate in revenue for the years ended December 31, 2011, 2012 and 2013, respectively. The VAT rebate revenues are classified into the relevant revenue categories.

Government Subsidies

'

Government subsidies

Government subsidies include amounts granted by local government authorities to encourage the employment of new college graduates and other purposes. Government subsidies are recorded as receivables when the approval is obtained from the local government authorities and the Group has the right to receive the subsidies, when historically the expenses that the subsidies intended to compensate normally have incurred by the Company. Subsidies to encourage employment of new college graduates are recognized in the statement of operations as deductions to the cost of revenues and related expenses, primarily costs of revenues. Subsidies for other purposes are recognized as other operating income because the subsidies are not intended to compensate for specific expenditure. For the years ended December 31, 2011, 2012 and 2013, the Group recognized government subsidies as a reduction to costs of revenues of $9,277, $13,845 and $11,019, respectively, as a reduction to operating expenses of $3,054, $3,192 and $1,594, respectively, and as other operating income of $1,840, $1,110 and $1,175, respectively.

Operating Leases

'

Operating leases

Leases where substantially all the rewards and risks of ownership of assets remain with the lessor are accounted for as operating lease. Payments made under operating leases are charged to the consolidated statements of operations on a straight-line basis over the lease periods.

Advertising Costs

'

Advertising costs

Advertising costs are expensed as incurred and such expenses were minimal for the periods presented. Advertising costs have been included as part of selling and marketing expenses.

Income Taxes

'

Income taxes

Current income taxes are provided for in accordance with the laws of the relevant tax authorities. Deferred income taxes are recognized for temporary differences between the tax bases of assets and liabilities and their reported amounts in the financial statements. Net operating loss carry forwards and credits are applied using 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. The components of the deferred tax assets and liabilities are individually classified as current and non-current based on their characteristics.

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 are classified as a component of the provisions for income taxes.

Foreign Currency Translation

'

Foreign currency translation

The functional and reporting currency of the Company is the United States dollar (“U.S. dollar”). The financial records of the Group’s subsidiaries and VIE located in the PRC, Japan, Hong Kong, Taiwan, Korea, Canada, Germany and the United States are maintained in their local currencies, the Renminbi (“RMB”), Japanese Yen (“Yen”), Hong Kong Dollars (“HK$”), Taiwan Dollars (“NT$”), Korea Won (“WON”), Canadian Dollars (“CAD”), Euro (“EUR”) and U.S. Dollars (“US$”), respectively, which are also the functional currencies of these entities.

Monetary assets and liabilities denominated in currencies other than the functional currency are translated into the functional currency at the prevailing rates of exchange on the balance sheet date. Transactions in currencies other than the functional currency during the year are converted into functional currency at the applicable rates of exchange prevailing when the transactions occurred. Transaction gains and losses are recognized in the statements of operations.

The Group’s entities with functional currency of RMB, Yen, HK$, NT$, WON, CAD and EUR translate their operating results and financial position into the U.S. dollar, the Group’s reporting currency, based on the exchange rates quoted by the Federal Reserve Bank of New York. Assets and liabilities are translated using the exchange rates in effect on the balance sheet date. Revenues, expenses, gains and losses are translated using the average rate for the year. Translation adjustments are report as cumulative translation adjustments and are shown as a separate component of the other comprehensive income.

Comprehensive Income

'

Comprehensive income

Comprehensive income is defined as the change in equity of a business enterprise during a period from transactions and other events and circumstances from non-owner sources and is presented in the Consolidated Statements of Comprehensive Income. Accumulated other comprehensive income (net of tax) at fiscal 2012 and 2013 year-ends are substantially comprised of accumulated foreign currency translation adjustments.

Share-based Compensation

'

Share-based compensation

The Group grants share options to its employees for retention and incentive purposes. The value of the share options is measured based on the fair value on the grant date. The Group recognizes compensation costs, net of a forfeiture rate, on a straight-line basis over the requisite service period, which is generally the vesting period of the award in accordance with the graded vesting schedule. The amount of compensation expenses recognized for any period is not less than the portion of the fair value of the options vested during that period. The estimate of forfeiture rate is adjusted over the requisite service period to the extent that actual forfeiture rate differs, or are expected to differ, from such estimates. Changes in estimated forfeiture rate are recognized through a cumulative true-up adjustment in the period of change and will impact the amount of share-based compensation expense to be recognized in future periods.

Shares awards issued to non-employees, such as consultants, are measured at fair value at the earlier of the commitment date or the date the service is completed, and are recognized over the period the service is provided in accordance with the graded vesting schedule.

Net Income Per Share

'

Net income per share

Basic net income per ordinary share is computed by dividing net income attributable to ordinary shareholders by the weighted average number of ordinary shares outstanding during the period.

Diluted net income per ordinary share reflects the potential dilution that could occur if securities or other contracts to issue ordinary shares were exercised or converted into ordinary shares.

The Group’s nonvested shares were participating securities, as certain nonvested shares were entitled to dividend right before vesting. Accordingly, the Group used the two-class method whereby undistributed net income was allocated on a pro rata basis to the ordinary, and certain nonvested shares to the extent that each class might share income for the period, whereas the undistributed net loss was allocated to ordinary shares and certain nonvested shares.

In periods where losses are reported, the weighted-average number of common shares outstanding excludes common stock equivalents, because their inclusion would be anti-dilutive.

Significant Risks and Uncertainties

'

Significant risks and uncertainties

Foreign currency risk

RMB is not freely convertible into other currencies. All foreign exchange transactions involving RMB must take place through the People’s Bank of China or other institutions authorized to buy and sell foreign currency. The exchange rate adopted for the foreign exchange transactions are the rates of exchange quoted by the Federal Reserve Bank of New York that are determined largely by supply and demand. The Group’s cash balances in RMB as of December 31, 2011, 2012 and 2013 were RMB473, 192,669, RMB531,962,381 and RMB478,731,600 respectively.

During the periods, the Group incurred foreign currency risk mainly on sales denominated in US$, and Japanese Yen. The Group did not enter into any foreign exchange forward contracts to hedge against exchange rate fluctuations.

Concentration of Credit Risk

'

Concentration of credit risk

Financial instruments that potentially expose the Group to concentration of credit risk consist primarily of cash and cash equivalents, restricted cash, and accounts receivable.

The Group places the majority of its cash and cash equivalents and restricted cash with financial institutions located in the PRC and the United States of America. The Group conducts credit evaluations of customers and generally do not require collateral or other security from their customers.

The Group has relatively high concentration of revenues with certain clients. Client accounting for 10% or more of total net revenues is as follows:

[1]	In September 2011, iSoftStone WOFE and Chengdu Investment Holding Group Ltd., a government investment group, jointly established Chengdu Medicine & Health Network Management Company Limited ("Chengdu-Medical") in Chengdu to design, build, and operate a healthcare data exchange network. The Group invested $7,785 to hold 49% of the equity of Chengdu-Medical and accounts for the investment using equity method. In January 2012, the Group transferred 9.8% of its equity interest in Chengdu-Medical to an unrelated Chengdu company, for an exchange of certain intellectual property rights relating to cloud computing. After the completion of the exchange, the Group holds 39.2% equity interest in Chengdu-Medical. The Group recognized share of loss of $95 and $303 during the year ended December 31, 2011 and 2012, respectively. The Group recognized share of gain of $72 in the year ended December 31, 2013.
[2]	In September 2012, iSoftStone WOFE and another two independent y investors established Guangdong IoT iSoftStone Information Technology Company Limited ("iSS-Foshan"). The Group invested $1,429 to hold 49% of the equity of iSS-Foshan. As the Group has the ability to exercise significant influence over the operating and financial decisions, equity method is used to account for the investment. In October 2013, the Group participated a capital call and contributed additional capital of $1,408 to iSS-Foshan to maintain 49% equity interest. During the year ended December 31 2012 and 2013, the Group recognized share of loss in iSS-Foshan at $200 and $414, respectively.

The Group determined and applied the cost method to account for the investment as the investment in preferred shares is not in-substance common stock.
[4]	In December 2013, iSoftStone Tianjin invested $165 to hold 11.1% of equity interest in setting up Changchun Microsoft Innovation Center Co. (" Microsoft Innovation"), Ltd. with other third party investors. The Group determined and applied the cost method to account for the investment in Microsoft Innovation.
