Areas of the consolidated financial statements where estimates may have the most significant effect include contractual and regulatory reserves, valuation and lives of tangible and intangible assets, contingent consideration related to business acquisitions, impairment of goodwill and long-lived assets, accrued liabilities, revenue recognition and costs to complete fixed-price contracts, bonus and other incentive compensation, stock-based compensation, reserves for tax benefits and valuation allowances on deferred tax assets, provisions for income taxes, collectability of receivables, and loss accruals for litigation.

The Company’s domestic bank accounts are insured up to $250,000 by the Federal Deposit Insurance Corporation. The majority of the Company’s cash transactions are processed through one U.S. commercial bank. Cash held domestically in excess of daily requirements is used to reduce any amounts outstanding under the Company’s Credit Facility. As of December 31, 2020 and 2019, the Company held approximately $81.5 million and $7.1 million, respectively, of cash and restricted cash in foreign bank accounts (not including outstanding deposits and checks). To date, the Company has not incurred losses related to cash and cash equivalents.</p> <p style="margin-top:6pt;margin-bottom:0pt;text-indent:5.24%;color:#000000;font-family:Times New Roman;font-size:10pt;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">The Company’s receivables consist principally of amounts due from agencies and departments of the federal government, state and local governments, and international governments, as well as from commercial organizations. T<span style="color:#000000;">he </span>credit risk, with<span style="color:#000000;"> respect to federal and other government clients, is limited due to the creditworthiness of the respective governmental entity. Amounts due for work performed as a subcontractor to a commercial organization also represent limited credit risk when the commercial client is performing as the prime contractor on a government contract due to the ultimate creditworthiness of the end client. </span>Receivables from commercial clients generally pose a greater credit risk, and, as a result, are subject to ongoing monitoring. The Company extends credit in the normal course of operations and does not require collateral from its clients.</p> <p style="margin-top:6pt;margin-bottom:0pt;text-indent:5.24%;color:#000000;font-family:Times New Roman;font-size:10pt;font-weight:normal;font-style:normal;text-transform:none;font-variant: normal;">The Company has historically been, and continues to be, heavily dependent on contracts with the federal government which are subject to audit by agencies and departments of the federal government. Such audits determine, among other things, whether an adjustment to invoices previously rendered are required under regulations as well as the underlying terms of each respective contract. Management does not expect significant adjustments as a result of government audits that will adversely affect the Company’s financial position and results of operations.</p>
