Organization, Consolidation and Presentation of Financial Statements [Abstract]
BASIS OF PRESENTATION	BASIS OF PRESENTATION The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles, or GAAP, and pursuant to the rules and regulations of the U.S. Securities and Exchange Commission, or SEC, and should be read in conjunction with the information contained in the Company's Annual Report on Form 10-K for the year ended March 31, 2022. The interim period unaudited condensed consolidated financial statements are presented as described below. Certain information and disclosures normally required for annual financial statements have been condensed or omitted pursuant to GAAP and SEC rules and regulations. In the opinion of management, all adjustments considered necessary for fair presentation of the results of the interim periods presented have been included. The Company’s fiscal year ends on March 31 and unless otherwise noted, references to fiscal year or fiscal are for fiscal years ended March 31. The results of operations for the three months ended June 30, 2022 are not necessarily indicative of results to be expected for the full fiscal year. The condensed consolidated financial statements and notes of the Company include its subsidiaries, and other entities over which the Company has a controlling financial interest or where the Company is a primary beneficiary. The Company uses the equity method to account for investments in entities that it does not control if it is otherwise able to exert significant influence over the entities' operating and financial policies. Equity investments in entities over which the Company does not have the ability to exercise significant influence and whose securities do not have a readily determinable fair value are carried at cost or cost net of other-than-temporary impairments. Certain amounts reported in the Company's prior year condensed consolidated financial statements have been reclassified to conform to the current year presentation. Accounting Estimates The preparation of financial statements in conformity with 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 financial statements, and the reported amounts of revenue and expenses during the reporting periods. Areas of the financial statements where estimates may have the most significant effect include the provision for claimed indirect costs, valuation and lives of tangible and intangible assets, impairment of long-lived assets, accrued liabilities, revenue recognition, including the accrual of indirect costs, bonus and other incentive compensation, stock-based compensation, reserves for uncertain tax positions and valuation allowances on deferred tax assets, provisions for income taxes, postretirement obligations, collectability of receivables, and loss accruals for litigation. Actual results experienced by the Company may differ materially from management's estimates. Recent Accounting Pronouncements Not Yet Adopted Accounting and reporting pronouncements effective after June 30, 2022 and issued through the filing date are not expected to have a material impact on the Company's condensed consolidated financial statements.

REVENUE

REVENUE	3 Months Ended
	Jun. 30, 2022
Revenue from Contract with Customer [Abstract]
REVENUE	REVENUEThe Company's revenues from contracts with customers (clients) are derived from offerings that include consulting, analytics, digital solutions, engineering, mission, and cyber services, substantially with the U.S. government and its agencies and, to a lesser extent, subcontractors. The Company also serves foreign governments, as well as domestic and international commercial clients. The Company performs under various types of contracts, which include cost-reimbursable contracts, time-and-materials contracts, and fixed-price contracts. Contract Estimates We recognize revenue for many of our contracts under a contract cost-based input method and require an Estimate-at-Completion ("EAC") process, which management uses to review and monitor the progress towards the completion of our performance obligations. Under this process, management considers various inputs and assumptions related to the EAC, including, but not limited to, progress towards completion, labor costs and productivity, material and subcontractor costs, and identified risks. Estimating the total cost at the completion of our performance obligations is subjective and requires management to make assumptions about future activity and cost drivers under the contract. Changes in these estimates can occur for a variety of reasons and, if significant, may impact the revenue and profitability of the Company’s contracts. Changes in estimates related to contracts accounted for under the EAC process are recognized on a cumulative catch-up basis in the period when such changes are determinable and reasonably estimable. If the estimate of contract profitability indicates an anticipated loss on a contract, the Company recognizes the total loss at the time it is identified. For each of the three months ended June 30, 2022 and 2021, the aggregate impact of adjustments in contract estimates was not material. Disaggregation of Revenue We disaggregate our revenue from contracts with customers by contract type, customer, as well as whether the Company acts as prime contractor or subcontractor, as we believe these categories best depict how the nature, amount, timing and uncertainty of our revenue and cash flows are affected by economic factors. The following series of tables presents our revenue disaggregated by these categories. Revenue by Contract Type: We generate revenue under the following three basic types of contracts: • Cost-Reimbursable Contracts: Cost-reimbursable contracts provide for the payment of allowable costs incurred during performance of the contract, up to a ceiling based on the amount that has been funded, plus a fixed fee or award fee. • Time-and-Materials Contracts: Under contracts in this category, we are paid a fixed hourly rate for each direct labor hour expended, and we are reimbursed for billable material costs and billable out-of-pocket expenses inclusive of allocable indirect costs. We assume the financial risk on time-and-materials contracts because our costs of performance may exceed negotiated hourly rates. • Fixed-Price Contracts: Under a fixed-price contract, we agree to perform the specified work for a predetermined price. To the extent our actual direct and allocated indirect costs decrease or increase from the estimates upon which the price was negotiated, we will generate more or less profit, respectively, or could incur a loss. The table below presents the total revenue for each type of contract: Three Months Ended 2022 2021 Cost-reimbursable $ 1,190,828 53 % $ 1,115,426 56 % Time-and-materials 545,902 24 % 497,449 25 % Fixed-price 512,870 23 % 376,191 19 % Total Revenue $ 2,249,600 100 % $ 1,989,066 100 % Revenue by Customer Type: Three Months Ended 2022 2021 U.S. government (1) : Defense Clients $ 1,019,991 45 % $ 973,605 49 % Intelligence Clients 408,883 18 % 379,174 19 % Civil Clients 757,714 34 % 592,796 30 % Total U.S. government 2,186,588 97 % 1,945,575 98 % Global Commercial Clients 63,012 3 % 43,491 2 % Total Revenue $ 2,249,600 100 % $ 1,989,066 100 % (1) Certain contracts were reassigned between the various verticals of our U.S. government business shown in the table above to better align our operations to the customers we serve within each market. Prior year revenue by customer type has been recast to reflect the changes. Revenue by Whether the Company Acts as a Prime Contractor or a Subcontractor: Three Months Ended 2022 2021 Prime Contractor $ 2,131,295 95 % $ 1,861,722 94 % Subcontractor 118,305 5 % 127,344 6 % Total Revenue $ 2,249,600 100 % $ 1,989,066 100 % Performance Obligations Remaining performance obligations represent the transaction price of exercised contracts for which work has not yet been performed, irrespective of whether funding has or has not been authorized and appropriated as of the date of exercise. Remaining performance obligations exclude negotiated but unexercised options, the unfunded value of expired contracts, and certain variable consideration which the Company does not expect to recognize as revenue. As of June 30, 2022 and March 31, 2022, the Company had $7.5 billion and $7.4 billion of remaining performance obligations, respectively. We expect to recognize approximately 70% of the remaining performance obligations at June 30, 2022 as revenue over the next 12 months, and approximately 85% over the next 24 months. The remainder is expected to be recognized thereafter. Contract Balances The Company's performance obligations are typically satisfied over time and revenue is generally recognized using a cost-based input method. Fixed-price contracts are typically billed to the customer using milestone or fixed monthly payments, while cost-reimbursable-plus-fee and time-and-material contracts are typically billed to the customer at periodic intervals (e.g. monthly or weekly) as indicated by the terms of the contract. Disparities between the timing of revenue recognition and customer billings and cash collections result in net contract assets or liabilities being recognized at the end of each reporting period. Contract assets primarily consist of unbilled receivables typically resulting from revenue recognized exceeding the amount billed to the customer and right to payment is not just subject to the passage of time. Unbilled amounts represent revenues for which billings have not been presented to customers. These amounts are generally billed and collected within one year subject to various conditions including, without limitation, appropriated and available funding. Long-term unbilled receivables not anticipated to be billed and collected within one year, which are primarily related to retainage, holdbacks, and long-term rate settlements to be billed at contract closeout, are included in other long-term assets in the accompanying condensed consolidated balance sheets. Contract liabilities primarily consist of advance payments, billings in excess of costs incurred and deferred revenue. Contract assets and liabilities are reported on a net contract basis at the end of each reporting period. The Company maintains an allowance for credit losses to provide for an estimate of uncollectible receivables. Provision for credit losses recognized was not material for the three months ended June 30, 2022 and 2021. The following table summarizes the contract assets and liabilities, and accounts receivable, net of allowance recognized on the Company’s condensed consolidated balance sheets: June 30, March 31, Current assets Accounts receivable–billed $ 627,774 $ 465,322 Accounts receivable–unbilled (contract assets) 1,200,602 1,157,667 Allowance for credit losses — — Accounts receivable, net 1,828,376 1,622,989 Other long-term assets Accounts receivable–unbilled (contract assets) 63,960 64,339 Total accounts receivable, net $ 1,892,336 $ 1,687,328 Other current liabilities Advance payments, billings in excess of costs incurred and deferred revenue (contract liabilities) $ 33,762 $ 26,747

EARNINGS PER SHARE

	Jun. 30, 2022
Earnings Per Share [Abstract]
EARNINGS PER SHARE	EARNINGS PER SHARE The Company computes basic and diluted earnings per share amounts based on net income attributable to common stockholders for the periods presented. The Company uses the weighted-average number of common shares outstanding during the period to calculate basic earnings per share, or EPS. Diluted EPS adjusts the weighted average number of shares outstanding to include the dilutive effect of outstanding common stock options and other stock-based awards. The Company currently has outstanding shares of Class A Common Stock. Unvested Class A Restricted Common Stock holders are entitled to participate in non-forfeitable dividends or other distributions. These unvested restricted shares participated in the Company's dividends declared and were paid in the first quarter of fiscal 2023 and 2022. As such, EPS is calculated using the two-class method whereby earnings are reduced by distributed earnings as well as any available undistributed earnings allocable to holders of unvested restricted shares. A reconciliation of the income used to compute basic and diluted EPS for the periods presented are as follows: Three Months Ended 2022 2021 Earnings for basic computations (1) $ 137,369 $ 91,621 Weighted-average common shares outstanding for basic computations 132,371,487 135,569,968 Earnings for diluted computations (1) $ 137,372 $ 91,622 Dilutive stock options and restricted stock 639,601 822,375 Weighted-average common shares outstanding for diluted computations 133,011,088 136,392,343 Earnings per common share Basic $ 1.04 $ 0.68 Diluted $ 1.03 $ 0.67 (1) During the three months ended June 30, 2022 and 2021, approximately 0.9 million and 0.7 million participating securities were paid dividends totaling $0.4 million and $0.3 million, respectively.

Business Combination and Asset Acquisition [Abstract]
ACQUISITIONS, DIVESTITURES, AND GOODWILL	ACQUISITIONS, DIVESTITURES, AND GOODWILL Acquisitions EverWatch On March 16, 2022, the Company announced that it had entered into a stock purchase agreement to acquire EverWatch Corp. ("EverWatch"), a leading provider of advanced solutions to the defense and intelligence communities for approximately $440.0 million, subject to customary adjustments. If consummated, the Company expects to fund the acquisition with cash on hand. The transaction is subject to satisfaction of customary closing conditions. On June 29, 2022, the U.S. Department of Justice (“DOJ”) initiated a lawsuit seeking to enjoin consummation of the transaction. In connection with the DOJ’s lawsuit, the Company and EverWatch agreed to delay any closing of the transaction until October 9, 2022 or the date on which the court denies the DOJ’s request for a preliminary injunction and/or permanent injunction, whichever is earlier. The DOJ litigation and related delay have introduced an increased level of uncertainty regarding the ability of the parties to consummate the transaction. The Company can make no assurances that the transaction will be consummated. Divestitures In April 2022, the Company entered into an agreement with Oliver Wyman, a global management consulting firm and a business of Marsh McLennan, to divest the Company's management consulting business serving the Middle East and North Africa (MENA) region, which is substantially comprised of the contracts associated with the MENA business and the team of management consultants that provide services under those contracts. The Company concluded that the assets and liabilities associated with the MENA business met the criteria to be reported as held for sale on the consolidated balance sheet as of March 31, 2022. As of June 30, 2022, $9.2 million of net accounts receivable, $0.7 million of other assets, $1.3 million of deferred revenue, $0.8 million of bonus payable, and $0.1 million of accounts payable were included in other current assets and other current liabilities on the consolidated balance sheet. The transaction is expected to close in fiscal 2023, subject to customary closing conditions, including regulatory approvals. Goodwill As of June 30, 2022 and March 31, 2022, goodwill was $2,021.9 million. As of June 30, 2022, approximately $7.9 million of goodwill has been allocated to the assets held for sale related to the Company's divestiture of its MENA business noted above.

("Booz Allen Hamilton") with a $1,225.3 million Term Loan A ("Term Loan A"), a $379.3 million Term Loan B ("Term Loan B", and, together with Term Loan A, the "Term Loans"), and a $1,000.0 million revolving credit facility (the "Revolving Credit Facility"), with a sub-limit for letters of credit of $200.0 million (collectively, the "Secured Credit Facility"). As of June 30, 2022, the maturity date of Term Loan A and Term Loan B are June 24, 2026 and November 26, 2026, respectively. Booz Allen Hamilton’s obligations and the guarantors’ guarantees under the Credit Agreement (the "Guarantee") are secured by a first priority lien on substantially all of the assets (including capital stock of subsidiaries) of Booz Allen Hamilton, Booz Allen Hamilton Investor Corporation, and the subsidiary guarantors, subject to certain exceptions set forth in the Credit Agreement and related documentation. At Booz Allen Hamilton’s option, borrowings under the Secured Credit Facility bear interest based either at LIBOR (adjusted for maximum reserves, and subject to a floor of zero) for the applicable interest period or a base rate (equal to the highest of (i) the administrative agent’s prime corporate rate, (ii) the overnight federal funds rate plus 0.50%, and (iii) three-month LIBOR (adjusted for maximum reserves, and subject to a floor of zero) plus 1.00%), in each case plus an applicable margin as determined by the pricing grid, payable at the end of the applicable interest period and in any event at least quarterly. The applicable margin for Term Loan A and borrowings under the Revolving Credit Facility ranges from 1.125% to 2.00% for LIBOR loans and 0.125% to 1.00% for base rate loans, in each case based on Booz Allen Hamilton’s consolidated total net leverage ratio. Unused commitments under the Revolving Credit Facility are subject to a quarterly fee ranging from 0.175% to 0.35% based on Booz Allen Hamilton’s consolidated total net leverage ratio. Booz Allen Hamilton also agreed to pay customary letter of credit and agency fees. The applicable margin for Term Loan B is 1.75% for LIBOR loans and 0.75% for base rate loans. The Credit Agreement requires quarterly principal payments of 1.25% of the stated principal amount of Term Loan A until maturity, and quarterly principal payments of 0.25% of the stated principal amount of Term Loan B until maturity. The Credit Agreement contains customary representations and warranties and customary affirmative and negative covenants. In addition, Booz Allen Hamilton is required to meet certain financial covenants at each quarter end, namely consolidated net total leverage and consolidated net interest coverage ratios. As of June 30, 2022 and March 31, 2022, Booz Allen Hamilton was in compliance with all financial covenants associated with its debt and debt-like instruments. For the three months ended June 30, 2022 and 2021, interest payments of $6.3 million and $4.9 million were made for Term Loan A, respectively, and $2.4 million and $1.8 million were made for Term Loan B, respectively. Borrowings under the Term Loans, and if used, the Revolving Credit Facility, incur interest at a variable rate. As of June 30, 2022, Booz Allen Hamilton had interest rate swaps with an aggregate notional amount of $550.0 million. These instruments hedge the variability of cash outflows for interest payments on the Term Loans and Revolving Credit Facility. The Company's objectives in using cash flow hedges are to reduce volatility due to interest rate movements and to add stability to interest expense (see Note 9 to our condensed consolidated financial statements). Senior Notes On June 17, 2021, Booz Allen Hamilton issued $500.0 million aggregate principal amounts of its 4.000% Senior Notes due July 1, 2029 (the “Senior Notes due 2029”) under an Indenture, dated as of June 17, 2021, among Booz Allen Hamilton, certain subsidiaries of Booz Allen Hamilton, as guarantors (the “2029 Subsidiary Guarantors”), and Wilmington Trust, National Association (in such capacity, the “2029 Trustee”), as supplemented by the First Supplemental Indenture, dated as of June 17, 2021, among Booz Allen Hamilton, the 2029 Subsidiary Guarantors and the 2029 Trustee. The Senior Notes due 2029 and the related guarantees are Booz Allen Hamilton’s and each 2029 Subsidiary Guarantor's senior unsecured obligations and rank equally in right of payment with all of Booz Allen Hamilton’s and the 2029 Subsidiary Guarantors’ existing and future senior indebtedness and rank senior in right of payment to any of Booz Allen Hamilton’s and the 2029 Subsidiary Guarantors’ future subordinated indebtedness. The net proceeds from the sale of the Senior Notes due 2029 were used to fund the acquisition of Liberty IT Solutions, LLC ("Liberty"), a leading digital partner driving transformation across the federal IT ecosystem, in June of 2021 and to pay related fees and expenses. Interest is payable on the Senior Notes due 2029 semi-annually in cash in arrears on July 1 and January 1 of each year, beginning on January 1, 2022. In connection with the issuance of the Senior Notes due 2029, the Company recognized $6.5 million of issuance costs, which were recorded as an offset against the carrying value of debt and will be amortized to interest expense over the term of the Senior Notes due 2029. On August 24, 2020, Booz Allen Hamilton issued $700.0 million aggregate principal amount of its 3.875% Senior Notes due 2028 (the “Senior Notes due 2028”, and, together with the Senior Notes due 2029, the "Senior Notes") under an Indenture, dated as of August 24, 2020, among Booz Allen Hamilton, certain subsidiaries of Booz Allen Hamilton, as guarantors (the “2028 Subsidiary Guarantors”), and Wilmington Trust, National Association as trustee (in such capacity, the “2028 Trustee”), as supplemented by the First Supplemental Indenture, dated as of August 24, 2020, among Booz Allen Hamilton, the 2028 Subsidiary Guarantors and the 2028 Trustee. Each of Booz Allen Hamilton's existing and future restricted subsidiaries that guarantee its obligations under the Secured Credit Facility or certain other indebtedness guarantee the Senior Notes due 2028 on a senior unsecured basis. The Senior Notes due 2028 and the guarantees are Booz Allen Hamilton’s and each 2028 Subsidiary Guarantors’ senior unsecured obligations and rank equally in right of payment with all of Booz Allen Hamilton’s and the 2028 Subsidiary Guarantors’ existing and future senior indebtedness and rank senior in right of payment to any of Booz Allen Hamilton’s and the Subsidiary Guarantors’ future subordinated indebtedness. Interest is payable on the Senior Notes due 2028 semi-annually on March 1 and September 1 of each year, beginning on March 1, 2021, and principal is due at maturity on September 1, 2028. In connection with the issuance of the Senior Notes due 2028, the Company recognized $9.2 million of issuance costs, which were recorded as an offset against the carrying value of debt and will be amortized to interest expense over the term of the Senior Notes due 2028. There were no changes to the Company’s outstanding debt obligations during the quarter. For additional information on the Company’s debt arrangements and default provisions, see Note 10, “Debt,” of the Company’s consolidated financial statements included in the fiscal 2022 Form 10-K. Interest on debt and debt-like instruments consisted of the following: Three Months Ended 2022 2021 (In thousands) Term Loan A Interest Expense $ 6,359 $ 5,229 Term Loan B Interest Expense $ 2,429 1,801 Interest on Revolving Credit Facility $ — 25 Senior Notes Interest Expense $ 11,781 7,559 Amortization of Debt Issuance Cost (DIC) and Original Issue Discount (OID) (1) $ 1,161 1,128 Interest Swap Expense $ 2,831 5,443 Other $ 94 85 Total Interest Expense $ 24,655 $ 21,270 (1) DIC and OID on the Term Loans and senior notes are recorded as a reduction of long-term debt in the condensed consolidated balance sheet and are amortized ratably over the life of the related debt using the effective rate method. DIC on the Revolving Credit Facility is recorded as a long-term asset on the condensed consolidated balance sheet and amortized ratably over the term of the Revolving Credit Facility.

DERIVATIVES

DERIVATIVES	3 Months Ended

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVES	DERIVATIVES The Company utilizes derivative financial instruments to manage interest rate risk related to its variable rate debt. The Company’s objectives in using these interest rate derivatives, which were designated as cash flow hedges, are to manage its exposure to interest rate movements and reduce volatility of interest expense. The aggregate notional amount of all interest rate swap agreements was $550.0 million as of June 30, 2022. The swaps have staggered maturities, ranging from June 30, 2023 to June 30, 2025. These swaps mature within the last tranche of the Company's floating rate debt (November 26, 2026). The floating-to-fixed interest rate swaps involve the exchange of variable interest amounts from a counterparty for the Company making fixed-rate interest payments over the life of the agreements without exchange of the underlying notional amount and effectively convert a portion of the variable rate debt into fixed interest rate debt. Derivative instruments are recorded in the condensed consolidated balance sheet on a gross basis at estimated fair value. As of June 30, 2022, $3.4 million and $4.1 million, were classified as other current assets and other long-term assets, respectively, on the condensed consolidated balance sheet. As of March 31, 2022, $4.1 million, $4.3 million and $39 thousand were classified as other long-term assets, other current liabilities, and other long-term liabilities, respectively, on the condensed consolidated balance sheet. For interest rate swaps designated as cash flow hedges, the changes in the fair value of derivatives is recorded in Accumulated Other Comprehensive Loss, or AOCL, net of taxes, and is subsequently reclassified into interest expense in the period that the hedged forecasted interest payments are made on the Company's variable-rate debt. The effect of derivative instruments on the accompanying condensed consolidated financial statements for the three months ended June 30, 2022 and 2021 is as follows: Three Months Ended June 30, Derivatives in Cash Flow Hedging Relationships Location of Gain or Loss Recognized in Income on Derivatives Amount of Pre-Tax Gain or (Loss) Recognized in AOCL on Derivatives Amount of Pre-Tax Gain or (Loss) Reclassified from AOCL into Income (1) 2022 2021 2022 2021 Interest rate swaps Interest expense $ 4,966 $ (1,394) $ (2,831) $ (5,443) (1) The reclassifications from accumulated other comprehensive loss to net income was reduced by taxes of $0.7 million and $1.4 million for the three months ended June 30, 2022 and 2021, respectively. Over the next 12 months, the Company estimates that $3.4 million will be reclassified as a decrease to interest expense. Cash flows associated with periodic settlements of interest rate swaps will be classified as operating activities in the condensed consolidated statement of cash flows. The Company is subject to counterparty risk in connection with its interest rate swap derivative contracts. Credit risk related to a derivative financial instrument represents the possibility that the counterparty will not fulfill the terms of the contract. The Company mitigates this credit risk by entering into agreements with credit-worthy counterparties and regularly reviews its credit exposure and the creditworthiness of the counterparties.

Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES The Company’s effective income tax rates were 23.1% and 22.9% for the three months ended June 30, 2022 and 2021. Our effective tax rates for these periods differ from the federal statutory rate 21.0% primarily due to the inclusion of state and foreign income taxes and permanent rate differences, which are predominantly related to certain executive compensation and the accrual of reserves for uncertain tax positions, offset by research and development tax credits, excess tax benefits for employee share-based compensation, and the Foreign Derived Intangible Income deduction. The Company is currently contesting tax assessments from the District of Columbia Office of Tax and Revenue ("DC OTR") for fiscal years 2013 through 2015. The assessment relates to $11.7 million of taxes, net of federal tax benefits, as of June 30, 2022. During fiscal 2022, the Company received notification that the District of Columbia Office of Administrative Hearings ruled in favor of the DC OTR.

FAIR VALUE MEASUREMENTS

FAIR VALUE MEASUREMENTS	3 Months Ended
	Jun. 30, 2022
Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS	FAIR VALUE MEASUREMENTS The accounting standard for fair value measurements establishes a three-tier value hierarchy, which prioritizes the inputs used in measuring fair value as follows: observable inputs such as quoted prices in active markets (Level 1); inputs other than quoted prices in active markets that are observable either directly or indirectly (Level 2); and unobservable inputs in which there is little or no market data, which requires the Company to develop its own assumptions (Level 3). A financial instrument's level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement. The financial instruments measured at fair value in the accompanying condensed consolidated balance sheets consist of the following: Recurring Fair Value Measurements Level 1 Level 2 Level 3 Total Assets: Current derivative instruments (2) $ — $ 3,424 $ — $ 3,424 Long-term deferred compensation plan asset (1) 20,186 — — 20,186 Long term derivative instruments (2) — 4,099 — 4,099 Total Assets $ 20,186 $ 7,523 $ — $ 27,709 Liabilities: Long-term deferred compensation plan liability (1) 20,186 — — 20,186 Total Liabilities $ 20,186 $ — $ — $ 20,186 Recurring Fair Value Measurements Level 1 Level 2 Level 3 Total Assets: Long-term deferred compensation plan asset (1) $ 16,512 $ — $ — $ 16,512 Long term derivative instruments (2) — 4,088 — 4,088 Total Assets $ 16,512 $ 4,088 $ — $ 20,600 Liabilities: Current derivative instruments (2) $ — $ 4,324 $ — $ 4,324 Long-term derivative instruments (2) — 39 — 39 Long-term deferred compensation plan liability (1) 16,512 — — 16,512 Total Liabilities $ 16,512 $ 4,363 $ — $ 20,875 (1) Investments in this category consist primarily of mutual funds whose fair values are determined by reference to the quoted market price per unit in active markets multiplied by the number of units held without consideration of transaction costs. These assets and liabilities represent investments held in a consolidated trust to fund the Company's non-qualified deferred compensation plan and are recorded in other long-term assets and other long-term liabilities on our condensed consolidated balance sheets. (2) The Company’s interest rate swaps are considered over-the-counter derivatives and fair value is estimated based on the present value of future cash flows using a model-derived valuation that uses Level 2 observable inputs such as interest rate yield curves. See Note 9 to the condensed consolidated financial statements for further discussion on the Company’s derivative instruments designated as cash flow hedges. The fair value of the Company's cash and cash equivalents, which are Level 1 inputs, approximated its carrying values at June 30, 2022 and March 31, 2022. The fair value of the Company's debt instruments approximated its carrying value at June 30, 2022 and March 31, 2022. The fair value of debt is determined using quoted prices or other market information obtained from recent trading activity of each debt tranche in markets that are not active (Level 2 inputs). The fair value is corroborated by prices derived from the interest rate spreads of recently completed leveraged loan transactions of a similar credit profile, industry, and terms to that of the Company. The fair value of the Senior Notes due 2029 and the Senior Notes due 2028 are determined using quoted prices or other market information obtained from recent trading activity in the high-yield bond market (Level 2 inputs).

COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES Letters of Credit and Third-Party Guarantees As of June 30, 2022 and March 31, 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 $7.7 million and $8.4 million, respectively. These letters of credit and bank guarantees primarily support insurance and bid and performance obligations. At both June 30, 2022 and March 31, 2022, approximately $1.0 million of these instruments reduced the available borrowings under the Revolving Credit Facility. The remainder is guaranteed under a separate $20.0 million facility of which $13.2 million and $12.6 million were available to the Company at June 30, 2022 and March 31, 2022, respectively. Government Contracting Matters - Provision for Claimed Indirect Costs For the three months ended June 30, 2022 and 2021, approximately 97% and 98%, respectively, 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. As noted in the Company's Annual Report on Form 10-K for the fiscal year ended March 31, 2022, 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 June 30, 2022 and March 31, 2022, the Company had recorded liabilities of approximately $295.6 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.
