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, expected recoverability from customers with contingent fee arrangements, 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 lease cost, depreciation and amortization periods, purchase price allocation, recoverability of long-lived assets including goodwill and intangibles, and estimated costs to complete fixed price contracts. </span></div><div style="text-indent:22.5pt;text-align:justify;"><span><br/></span></div><div style="text-indent:22.5pt;text-align:justify;"><span style="background-color:rgb(255,255,255, 0.0);color:#000000;font-family:'Times New Roman',sans-serif;font-size:10pt;font-weight:400;line-height:115%;">As of June 30, 2020, 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.</span></div>
