CY2021Q1	us-gaap	Use Of Estimates UseOfEstimates	Use of EstimatesThe preparation of the unaudited 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 and disclosure of contingent assets and liabilities at the date of the unaudited consolidated financial statements and the unaudited consolidated statements of income during the reporting period. Although these estimates are based on management’s best assessment of the current business environment, actual results may be different from those estimates. The significant estimates and assumptions that affect the unaudited consolidated financial statements include, but are not limited to, allowance for expected credit losses, the nature and timing of the satisfaction of performance obligations, the standalone selling price of performance obligations, and variable consideration in a customer contract, expected recoverability from customers with contingent fee arrangements, estimated costs to complete fixed price contracts, recoverability of dues from statutory authorities, assets and obligations related to employee benefit plans, deferred tax valuation allowances, income-tax uncertainties and other contingencies, valuation of derivative financial instruments, assumptions used to calculate stock-based compensation expense, assumptions used to determine the incremental borrowing rate to calculate lease liabilities and right-of-use (“ROU”) assets, lease term to calculate amortization of ROU, depreciation and amortization periods, purchase price allocation and recoverability of long-lived assets, goodwill and intangibles.As of March 31, 2021, the extent to which the global Coronavirus Disease 2019 pandemic (“COVID-19”) will ultimately impact the Company's business depends on numerous dynamic factors, which the Company still cannot reliably predict. As a result, many of the Company's estimates and assumptions herein required increased judgment and carry a higher degree of variability and volatility. As events continue to evolve with respect to COVID-19, the Company’s estimates may materially change in future periods. Any changes in estimates are adjusted prospectively in the Company’s consolidated financial statements.
