Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Letters of Credit and Third-Party Guarantees As of March 31, 2023 and 2022, the Company was contingently liable under open standby letters of credit and bank guarantees issued by our banks in favor of third parties that totaled $6.1 million and $8.4 million, respectively. These letters of credit and bank guarantees primarily support insurance and bid and performance obligations. At March 31, 2023 and 2022, approximately $1.3 million and $1.0 million of these instruments reduce the available borrowings under the Revolving Credit Facility. The remainder is guaranteed under a separate $7.5 million facility of which $2.7 million was available to the Company at March 31, 2023. In fiscal 2022, the remainder was guaranteed under a separate $20.0 million facility of which $12.6 million was available to the Company at March 31, 2022. Government Contracting Matters - Provision for Claimed Indirect Costs For each of the fiscal years 2023, 2022, and 2021, approximately 97% of the Company’s revenue was generated from contracts where the end user was an agency or department of the U.S. government, including contracts where the Company performed either as a prime contractor or subcontractor, and regardless of the geographic location in which the work was performed. U.S. government contracts and subcontracts are subject to extensive legal and regulatory requirements. From time to time and in the ordinary course of business, agencies of the U.S. government, including the Defense Contract Audit Agency (“DCAA”), audit the Company’s claimed indirect costs and conduct inquiries and investigations of our business practices with respect to government contracts to determine whether the Company's operations are conducted in accordance with these requirements and the terms of the relevant contracts. Management believes it has recorded the appropriate provision for claimed indirect costs for any audit, inquiry, or investigation of which it is aware that may be subject to any reductions and/or penalties. As of March 31, 2023 and 2022, the Company had recorded liabilities of approximately $326.7 million and $290.4 million, respectively, for estimated adjustments to claimed indirect costs based on its historical DCAA audit results, including the final resolution of such audits with the Defense Contract Management Agency, for claimed indirect costs incurred subsequent to fiscal 2011, and for contracts not yet closed that are subject to audit and final resolution. Litigation Our performance under U.S. government contracts and compliance with the terms of those contracts and applicable laws and regulations are subject to continuous audit, review, and investigation by the U.S. government, which may include such investigative techniques as subpoenas or civil investigative demands. Given the nature of our business, these audits, reviews, and investigations may focus, among other areas, on various aspects of procurement integrity, labor time reporting, sensitive and/or classified information access and control, executive compensation, and post government employment restrictions. We are not always aware of our status in such matters, but we are currently aware of certain pending audits and investigations involving labor time reporting, procurement integrity, and classified information access. In addition, from time to time, we are also involved in legal proceedings and investigations arising in the ordinary course of business, including those relating to employment matters, relationships with clients and contractors, intellectual property disputes, and other business matters. These legal proceedings seek various remedies, including claims for monetary damages in varying amounts, none of which are considered material, or are unspecified as to amount. Although the outcome of any such matter is inherently uncertain and may be materially adverse, based on current information, we do not expect any of the currently ongoing audits, reviews, investigations, or litigation to have a material adverse effect on our financial condition and results of operations. As of March 31, 2023 and 2022, there were no material amounts accrued in the consolidated financial statements related to these proceedings.
