Basis of presentation and significant accounting policies | 2. Basis of presentation and significant accounting policies Basis of presentation The functional currency of the majority of the Group's subsidiaries is the United States dollars ("USD"). The Group operates in a multi-currency environment having transactions in such currencies as the euros ("EUR"), British pounds ("GBP"), Romanian lei ("RON"), Polish złoty ("PLN"), Swiss francs ("CHF"), Russian rubles ("RUR") and others. The subsidiaries maintain their accounting records in accordance with the local or statutory requirements of the jurisdictions in which they are incorporated. The accompanying consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles ("US GAAP"). The accompanying consolidated financial statements differ from the financial statements of the subsidiaries issued for statutory purposes because they reflect certain adjustments, not recorded in the respective statutory accounting books that are appropriate to present the financial position, results of operations and cash flows. Principles of consolidation The accompanying consolidated financial statements include the accounts of the Company and its wholly and majority owned Subsidiaries. This generally includes all companies over which the Company directly or indirectly exercises control, which generally means that the Group owns more than 50% of the voting rights in the Subsidiary. Consolidation is also required when the Company is subject to a majority of the risk of loss or is entitled to receive a majority of the residual returns or both from a variable interest entity's activities. The financial statements of the Subsidiaries are prepared for the same reporting period as the Company, using consistent accounting policies. Adjustments are made to conform any dissimilar material accounting policies that may exist. All intercompany accounts and transactions have been eliminated from the consolidated financial statements. The list of subsidiaries of the Group is the following: % of ownership as Subsidiary 2017 2016 Luxoft International Company Ltd. % % Excelian (Singapore) Pte Ltd % % Symtavision Inc(1). n/a % Symtavision GmbH % % Luxoft Luxembourg S.a.r.l % % Luxoft Sweden % % Luxoft Netherlands B.V. % % Luxoft UK Ltd. % % Excelian Ltd.

Foreign currency translation For the majority of the Subsidiaries, the functional currency is USD because the majority of their revenues, expenditures, debt and trade liabilities are either priced, incurred, payable or otherwise measured in USD. Transactions and balances not already measured in the functional currency have been re-measured in USD in accordance with the relevant provisions of ASC 830 Foreign Currency Matters. Monetary assets and liabilities denominated in currencies different from the functional currencies are re-measured at exchange rates prevailing on the balance sheet dates: March 31, 2017 March 31, 2016 March 31, 2015 US 1$ = 0.997 CHF US 1$ = 0.9650 CHF US 1$ = 1.0389 CHF US 1$ = 56.3779 RUR US 1$ = 67.6076 RUR US 1$ = 58.4643 RUR US 1$ = 27.015 UAH US 1$ = 26.2181 UAH US 1$ = 23.4426 UAH US 1$ = 0.93 EUR US 1$ = 0.88 EUR US 1$ = 0.92 EUR US 1$ = 4.244 RON US 1$ = 3.9349 RON US 1$ = 4.1115 RON US 1$ = 0.8053 GBP US 1$ = 0.69 GBP US 1$ = 0.67 GBP US 1$ = 3.946 PLN US 1$ = 3.759 PLN US 1$ = 3.776 PLN Non-monetary assets and liabilities, capital, revenues and costs are re-measured at historical exchange rates prevailing on the relevant transaction dates. Gains and losses on foreign currency transactions are charged or credited to operations. The Group uses the U.S. dollar as its reporting currency. Therefore, the financial statements of the Subsidiaries that use a functional currency other than USD are translated into USD in accordance with ASC 830 using the current rate method. Assets and liabilities are translated at the rate of exchange prevailing at the balance sheet dates. Shareholders' equity is translated at the applicable historical rate. Revenue and expenses are translated at the monthly average rates of exchange. Translation gains and losses are included in accumulated other comprehensive income. Comprehensive income ASC 220 Comprehensive Income , requires the reporting of comprehensive income in addition to net income. Comprehensive income is defined as the change in equity of a business enterprise during a period from non-owner sources. Comprehensive income consists of foreign currency translation adjustments; effective portion of gains and losses on forward contracts that are designated as, and qualify as, cash flow hedges in accordance with ASC Subtopic No. 815-20, Hedging—General ; and adjustments to record changes in the funded status of the Group's defined benefit pension plan in accordance with ASC Subtopic No. 715-30, Defined Benefit Plans—Pension . Cash and cash equivalents The Group considers all highly liquid investments with a maturity of 90 days or less from the time of purchase to be cash equivalents. Restricted cash Restricted cash is represented by deposits on escrow accounts, related to new businesses acquisitions. As of March 31, 2017, the Group had $5,399 as restricted cash. Accounts receivable, net Accounts receivable are non-interest bearing and shown at their net realizable value, which approximates their fair value. Allowances for doubtful accounts are made for specific accounts in which collectability is doubtful, the Group does not make any general allowance based on the aging of accounts receivable. Recoveries of losses from accounts receivable written-off in prior years are presented within income from operations in the Group's consolidated statements of comprehensive income. Collections in respect of prior year write-offs amounted to $60 for the year ended March 31, 2017; $818 for the year ended March 31, 2016 and $501 for the year ended March 31, 2015. The table below summarizes changes in qualifying accounts for the years ended March 31, 2015, 2016 and 2017: Balance at the Charged to Reversals / Balance at the Allowance for doubtful accounts For the year ended March 31, 2015 ) For the year ended March 31, 2016 ) For the year ended March 31, 2017 ) Work-in-progress Work-in-progress includes costs related to uncompleted contract stages. Costs include direct costs such as professional compensation (payroll and related benefits), subcontracting, travel, materials and other items. Property and equipment Property and equipment are carried at cost less accumulated depreciation. Depreciation is computed over the estimated useful lives of depreciable assets using the straight-line method. The estimated useful lives for property and equipment are as follows: Buildings 25 years Furniture and fixtures and motor vehicles 5 years Exhibition and demonstration equipment 3 - 4 years Assets under capital lease 3 years Computers and office equipment 3 years Capitalized software 3 years Leasehold improvements according to lease contracts Goodwill and Long-lived intangible assets Goodwill represents an excess of the cost of business acquired over the fair value of identifiable net assets at the date of acquisition. Intangible assets, principally software and acquired contract-based customer relationships, software and brands are amortized on a straight-line basis over their estimated useful lives, on average 5 to 10 years. The Group does not have any intangible assets with indefinite useful lives. Goodwill and Long-lived intangible assets are reviewed for impairment annually or whenever it is determined that one or more impairment indicators exist. Upon such review, the Group considers the following factors: under-performance of the reporting unit or significant changes in its projected results; changes in the manner of utilization of an asset; severe and sustained declines in the traded price of the Company's common stock that are not attributable to factors other than the underlying value of its assets; negative market conditions or economic trends; changes in technology; new legislation, and other factors. The Group determines whether impairment has occurred by assigning goodwill to the reporting unit identified in accordance with ASC 350 Intangibles—Goodwill and Other , and comparing the carrying amount of the reporting unit to the fair value of the reporting unit. If an impairment of goodwill has occurred, the Group recognizes a loss for the difference between the carrying amount and the implied fair value of goodwill. See also Impairment of Long lived assets and Note 7, Impairment loss, below. Software costs Under the provisions of ASC 350 Intangibles—Goodwill and Other , the Group capitalizes costs associated with software developed or obtained for internal use when both the preliminary project stage is completed and the Group's management has authorized further funding of the project which it deems probable to be completed and used to perform the function intended. Capitalization of such costs ceases no later than the point at which the project is substantially complete and ready for its intended purpose. Capitalized software development costs are amortized using the straight-line method over the expected useful life of the software (generally 3 to 5 years). Research and development costs Research and development costs are expensed as incurred. Impairment of Long-lived assets In accordance with ASC 360 Property, Plant, and Equipment , and ASC 205 Presentation of Financial Statements , long-lived assets to be held and used by the Group, including intangible assets that are subject to amortization are reviewed to determine whether an event or change in circumstances indicates that the carrying amount of the asset may not be recoverable. For long-lived assets to be held and used, the Group bases its evaluation on such impairment indicators as the nature of the assets, the future economic benefit of the assets, any historical or future profitability measurements, as well as other external market conditions or factors that may be present. When such impairment indicators are present or other factors exist that indicate that the carrying amount of these of an undiscounted cash flow analysis of assets at the lowest level for which identifiable cash flows exist. If impairment has occurred, the Group recognizes a loss for the difference between the carrying amount and the fair value of the asset. The fair value of the asset is measured using discounted cash flow analysis or other valuation techniques. As of March 31, 2017, the Group performed its impairment review, which resulted in impairment loss of $5,287 attributable to the client base recognized upon acquisition of Insys Group Inc. No impairment expense related to long-lived assets was recognized during the years ending March 31, 2016 and 2015. See below—" Fair value measurement and Intangible Assets Impairment Tests" and Note 7, Impairment loss, for valuation techniques and quantitative information about the significant unobservable inputs used in the fair value measurement. Income taxes The Group computes and records income tax expense in accordance with ASC 740, Income Taxes . Under the asset and liability method, deferred tax assets and liabilities are determined based on differences between the financial reporting and tax bases of assets and liabilities at each reporting date, and are measured using the enacted tax rates and laws that will be in effect when differences are expected to reverse. ASC 740 Income Taxes , clarifies the accounting for uncertainty in income taxes. ASC 740 prescribes a recognition threshold and measurement attribute for the recognition and measurement of a tax position taken or expected to be taken in a tax return. It also provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure and transition. The Group believes that its recognized income tax filing positions will be sustained on audit and does not anticipate any adjustments that will result in a material change to its financial position. However, the Group cannot predict with certainty the interpretations or positions that tax authorities may take regarding specific tax returns filed by the Group. Revenue recognition The Group generates revenues primarily from software development services, including in such areas of competence as (a) custom software development and support, (b) product engineering and testing and (c) technology consulting. The Group recognizes revenues when realized or realizable and earned, which is when the following criteria are met: persuasive evidence of an arrangement exists; delivery has occurred; the sales price is fixed or determinable; and collectability is reasonably assured. The Group recognizes sales from time-and-material contracts as services are performed, based on actual hours and applicable billing rates, using the proportional performance method, with the corresponding cost of providing those services reflected as cost of sales. The majority of such sales are billed on a monthly basis whereby actual time is charged directly to the client at negotiated hourly billing rates. The Group recognizes sales from fixed price contracts based on the proportional performance method, during the period in which amounts become billable in accordance with the terms of the Group's contracts. Services under fixed price contracts are delivered in stages. Revenues recognized for completed stages are generally representative of the percentage of completion of the entire contract, as they are based on hours incurred compared to the total hours estimated for the completion of the entire contract. Costs related to completed stages are expensed as incurred, while those related to uncompleted stages are recorded in work-in-progress on the balance sheet. In instances where final acceptance is specified by the client, sales are deferred until all acceptance criteria have been met. In the absence of a sufficient basis to measure progress towards completion, sales are recognized upon receipt of final acceptance from the client. Revenue is stated net of any value-added taxes ("VAT") or other similar indirect taxes charged to clients. The Group enters into multiple elements arrangements with the customers that purchase license and further maintenance and support. The Group accounts for these revenues in accordance with guidance of ASC 605-25, Revenue recognition—multiple elements arrangements . The selling price of each element is based on vendor specific objective evidence ("VSOE") if available or estimated selling price. The estimation of selling price is made through consultation with and approval by the Group's management, taking into consideration the Group's pricing model and go-to-market strategy. Some of the software arrangements include consulting implementation services sold. Consulting revenues from these arrangements are generally accounted for separately from new software licenses revenues because the arrangements qualify as services transactions as defined in ASC 985-605, Revenue recognition—Software . The more significant factors considered in determining whether the revenues should be accounted for separately include the nature of services (i.e., consideration of whether the services are essential to the functionality of the licensed product), degree of risk, availability of services from other vendors, timing of payments and impact of milestones or acceptance criteria on the realizability of the software license fee. Revenues for consulting services are generally recognized as the services are performed. For multiple element arrangements under time-and-material contracts, revenue is recognized as services are performed for each deliverable. For arrangements under fixed-price contracts, software development revenue is recognized upon delivery of development services under the proportional performance method, as described above and for support services—on a straight-line basis over the support period, which is generally from 6 months to a year. The Group reports gross reimbursable travel and "out-of-pocket" expenses incurred as both sales and cost of sales in the consolidated statements of operations. Warranty Costs In most contracts the Group warrants that the technology solutions it developed for its clients would operate in accordance with the project specifications without defects for a specified warranty period. In the event that defects that the Group is held responsible for are discovered during the warranty period, the Group is obligated to remedy the defects. The Group provides for the estimated cost of warranties at the time the related revenue is recognized based on historical and projected warranty claim rates, historical and projected cost-per-claim and knowledge of specific product failures that are outside of the Group's typical experience. The Group has never incurred any material amounts with respect to the warranties for its solutions. Each quarter, the Group re-evaluates these estimates to assess the adequacy of its recorded warranty liabilities considering the size of the installed base of products subject to warranty protection and adjusts the amounts as necessary. If actual product failure rates or repair costs differ from estimates, revisions to the estimated warranty liabilities would be required and could materially affect the Group's results of operations. Cash Flow The Group utilizes invoice discounting and receivable purchase facilities as a source of short-term borrowings. The volume of such borrowings decreased significantly since the year ended March 31, 2016 as the Group changed the presentation for the year ended March 31, 2015 and 2016. Due to the fact that all short-term borrowings of the Group have quick turnover and short maturities the Group chooses, in accordance with ASC 230-10-45-8, Statement of Cash Flows—Other Presentation Matters , to present only net changes during the period in the Statement of Cash Flows, because the knowledge of the gross cash receipts and payments related to them is believed to be not necessary to understand the Group's financing activities. Government Grants The Group participates in government grants programs in several countries. Due to the absence of authoritative regulations for government grants in U.S. GAAP, the Group refers to IAS 20 guidance as to a non-authoritative source. The company evaluates a received grant as related to expenses or losses already incurred and recognizes it in profit or loss of the period in which the grant becomes receivable. Business combinations The Group accounts for its business acquisitions under the purchase method. The total cost of an acquisition is allocated to the underlying assets, including intangible assets acquired, and liabilities assumed based on their respective estimated fair values. Determining the fair value of assets acquired and liabilities assumed requires management's judgment and often involves the use of significant estimates and assumptions, including assumptions with respect to future cash inflows and outflows, discount rates, intangible and other asset lives and market multiples, among other items. The results of operations of acquired companies are included in the consolidated financial statements from the date of acquisition. After control is obtained, changes in ownership interests in subsidiaries that do not result in a loss of control are accounted for as equity transactions. Acquisition-related costs are costs the Group incurs to effect a business combination. Those costs include advisory, legal, accounting, valuation, and other professional or consulting fees; general administrative costs, including the costs of maintaining an internal acquisitions department; and costs of registering and issuing debt and equity securities. The Group accounts for acquisition-related costs as expenses in the periods in which the costs are incurred and the services are received. Advertising The Group expenses the cost of advertising as incurred. Advertising expenses for the years ended March 31, 2017, 2016 and 2015 were $3,316, $2,942 and $2,281 respectively, and are classified as selling expenses. Social contributions The Group contributes to various government pension and social funds in accordance with the legislation applicable to each of the subsidiaries. The employer's part of these contributions amounted to approximately, $42,824, $31,284 and $20,608 for the years ended March 31, 2017, 2016 and 2015, respectively, and was expensed as incurred. The majority of social contributions are made by subsidiaries in Poland, Romania, USA and Russia where social contributions charges is a mandatory tax consisting of contributions paid by employers at their own expense and on behalf of employees to the relevant pension, social security, medical and other similar funds. In most countries, where subsidiaries of the Company are located, the social contributions tax rate varies depending on employee's annual compensation and maximum taxable amount of annual or monthly compensation. Derivative financial instruments To protect itself from possible changes related to forecasted transactions denominated in currencies different from U.S. dollars, the Group uses forward currency exchange contracts. In accordance with ASC 815 Derivatives and Hedging , the Group recognizes all derivative financial instruments, such as foreign exchange contracts at fair value. Estimates of fair value were determined in accordance with ASC 820 Fair Value Measurements . Due to increased volume of hedged transactions and extended periods of foreign exchange contracts there is a risk of significant fluctuations of fair values of derivatives, affecting the Company's Statement of Comprehensive income. In order to reduce such fluctuations, the Group started to apply hedge accounting to forward contracts offsetting its forecasted transactions denominated in euro and British pounds in accordance with the guidance of ASC 815-30, Cash Flow Hedges . The forward contracts concluded in 2016 calendar year are designed so that the critical terms of the hedging instrument and of the hedged forecasted transaction are the same, therefore there is no ineffectiveness to be recognized in earnings, and the Group recognizes all gain or loss on a derivative instrument designated as a cash flow hedge in other comprehensive income. Amounts in accumulated other comprehensive income are reclassified into earnings in the same period when the hedged forecasted transaction affects earnings, i.e. when a forecasted sale actually occurs or an expense is incurred. Gains or losses related to hedge of forecasted sales are recognized in Sales of services, and those attributable to forecasted expense are recognized in Cost of services. Forward contracts concluded before January 2016 were not designated as cash flow hedge at inception and did not qualify for hedge accounting as defined by ASC 815. Gain or loss on revaluation of these contracts is recognized directly in earnings as gain or loss from foreign currency exchange contract. In October 2016, as the euro started to depreciate against the US dollar, the Group decided to early close some of its forward euro contracts with maturity dates in 6 months or more. In accordance with ASC 815-30-40-1 and 40-2, the Group calculated the fair value of these contracts and recognized the result of the valuation in accumulated other comprehensive income. The net gain in the amount of $22 remains in the accumulated other comprehensive income until reclassified into earnings in the same periods during which the hedged forecasted transaction affects earnings. All further changes in the fair value of de-designated hedges were recognized directly in earnings in the period of revaluation. In order to lock the speculation gain achieved by the early closing, in November 2016, the Group entered into reverse contracts, i.e. to buy euros for US dollars. The new contracts matched those de-designated both in the amounts and maturity dates, resulting in early fixing of the results of the deals. The result of matching the pairs of forward contracts in amount of $941 was recognized in the earnings for the year ended March 31, 2017. Concentration of credit risk The concentrations of credit risk associated with trade and other receivables are mitigated by ongoing procedures to monitor the creditworthiness of customers and other debtors. As of March 31, 2017, the largest clients' balances accounted for 18%, 18%, 6%, 6% and 3% of the total Group's accounts receivable. As of March 31, 2016, the largest clients' balances accounted for 30%, 22%, 7%, 4% and 3% of the total Group's accounts receivable. As of March 31, 2015, the largest clients' balances accounted for 32%, 21%, 9%, 4% and 3% of the total Group's accounts receivable. For the year ended March 31, 2017, the same customers accounted for 23%, 20%, 6%, 3% and 2% of the Group's revenues. For the year ended March 31, 2016, the same customers accounted for 30%, 22%, 7%, 3% and 3% of the Group's revenues. For the year ended March 31, 2015, the same customers accounted for 36%, 20%, 8%, 4% and 4% of the Group's revenues. Use of estimates in preparation of financial statements The preparation of these consolidated financial statements, in conformity with US GAAP, requires management to make estimates and assumptions that affect amounts in the financial statements and accompanying notes and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Fair value of financial instruments The fair value of financial instruments, including cash and cash equivalents, short-term borrowings, which are included in current assets and liabilities, accounts receivable and accounts payable approximate the carrying value of these items due to the short-term maturities of such instruments. Fair value measurement and Intangible Assets Impairment Tests The Group follows the provisions of ASC 820 Fair Value Measurements and Disclosures , and considers the following three levels of inputs to measure the fair value: Level 1: Quoted prices for identical assets or liabilities in active markets that the entity has the ability to access as of the measurement date. Level 2: Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are non-active; inputs other than quoted prices that are observable and derived from or corroborated by observable market data. The Group classifies its derivative assets and liabilities as Level 2. The fair value of foreign currency forward and option contracts are based on internally developed valuation models that discount cash flows resulting from the differential between the contractual foreign currency exchange rate and the reporting date market-based forward foreign currency exchange rate for a similar instrument. Level 3: Valuations derived from valuation techniques in which one or more significant inputs are unobservable. The Group used Level 3 inputs when determining the fair value of contingent payable for business acquisitions (Note 3); contingent payable for software acquisition (Note 9); reportable unit for the purposes of determining goodwill impairment; intangible assets for the purposes of determining their impairment (see Note 7), and the value of shares issued under the stock option plans of the Company (Note 18). In determining the estimated fair values of the reporting units and intangible assets, the Group employed a Discounted Cash Flow ("DCF") analysis. Determining estimated fair values requires the application of significant judgment. The basis for the Group's cash flow assumptions includes attributable forecasted revenue, operating costs and other relevant factors, including estimated capital expenditures. Assumptions under this method have been adjusted to reflect increased risk due to current economic volatility. In addition to that, the Group has to estimate the applicable discount rate and the terminal growth rates, where applicable. The significant unobservable inputs used in the fair value estimations are as following: • Cost of capital: The cost of capital reflects the return a hypothetical market participant would require for a long-term investment in an asset and can be viewed as a proxy for the risk of that asset. Changes in the financial markets, such as an increase in interest rates or an increase in the expected required return on equity by market participants within the industry, could increase the discount rate, thus decreasing the fair value of the assets. The cost of capital used by the Group in its analysis ranged from 11% to 20% based on the level of risk related to each particular asset or reporting unit. • Cost of debt: The cost of debt reflects the effective rate paid for use of current debt facilities. The cost of debt used by the Group in its analysis ranged from 2.5% to 4.0%. • Short- and medium-term growth rates: Short- and medium-term growth rates reflect the level of economic growth in each of the Group's markets from the last forecasted period. These assumptions are inherently uncertain and are subject to management discretion based on reasonable market expectations and the company's performance. • Forecasted operating costs: The level of cash flow generated by each operation is ultimately governed by the extent to which the Group manages the relationship between revenues and costs. The Group forecasts the level of operating costs by reference to (a) the historical absolute and relative levels of costs the Group has incurred in generating revenue, (b) the operating strategy of each business, (c) specific forecasted operating costs to be incurred and (d) expectations as to what these costs would be for an average market participant. The Group's estimates of forecasted operating costs are developed from a number of external sources, in combination with a process of on-going consultation with operational management. • Forecasted capital expenditure: The size and phasing of capital expenditure, both recurring expenditure to replace retired assets and investments in new projects, has a significant impact on cash flows. The Group forecasts the level of future capital expenditure based on current strategies and specific forecast costs to be incurred, as well as expectations of what these costs would be like for an average market participant. The Group's estimate of forecasted capital expenditure is developed from a number of external sources, in combination with a process of on-going consultation with operational management. The most significant unobservable input used in the valuation of contingent payable is discount rate. Cost of debt is applied when the certainty of future payments is higher and cost of capital is applied where the certainty of future payments is lower. The fair value of Group's assets and liabilities measured at fair value at the reporting date is presented below: As of March 31, 2017 Total Level 1 Level 2 Level 3 Recurring fair value measurements Contingent consideration — — Foreign currency derivatives asset — — Foreign currency derivatives liability ) — ) — ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Total recurring fair value measurements $ $ — $ $ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ The Group's policy is to recognize transfers to and out of Level 3 as of the date of change in circumstances that caused the transfer.
