Organization Consolidation And Presentation Of Financial Statements [Abstract]
ORGANIZATION AND BASIS OF PRESENTATION	NOTE 1. ORGANIZATION AND BASIS OF PRESENTATION Business Activities CACI International Inc (collectively, with its consolidated subsidiaries, the Company, we, us and our) is a leading provider of information solutions and services primarily to the U.S. government. Other customers include state and local governments, commercial enterprises and agencies of foreign governments. The Company’s operations are subject to certain risks and uncertainties including, among others, the dependence on contracts with federal government agencies, dependence on revenue derived from contracts awarded through competitive bidding, existence of contracts with fixed pricing, dependence on subcontractors to fulfill contractual obligations, dependence on key management personnel, ability to attract and retain qualified employees, ability to successfully integrate acquired companies, and current and potential competitors with greater resources. Basis of Presentation The accompanying consolidated financial statements of the Company have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (SEC) and include the assets, liabilities, results of operations and cash flows for the Company, including its subsidiaries and ventures that are majority-owned or otherwise controlled by the Company. All intercompany balances and transactions have been eliminated in consolidation.

Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	NOTE 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Use of Estimates The preparation of financial statements in conformity with generally accepted accounting principles in the United States (GAAP) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the consolidated financial statements, and the reported amounts of revenue and expenses during the reported periods. The most significant of these estimates and assumptions relate to estimating contract revenue and costs, measuring progress against the Company’s performance obligations, assessing the fair value of acquired assets and liabilities accounted for through business acquisitions, valuing and determining the amortization periods for long-lived intangible assets, assessing the recoverability of long-lived assets, reserves for accounts receivable, and reserves for contract related matters. Management evaluates its estimates on an ongoing basis using the most current and available information. However, actual results may differ significantly from estimates. Changes in estimates are recorded in the period in which they become known. Revenue Recognition The Company generates almost all of our revenue from three different types of contractual arrangements with the U.S. government: cost-plus-fee, fixed-price, and time-and-materials (T&M) contracts. Our contracts with the U.S. government are generally subject to the Federal Acquisition Regulation (FAR) and are competitively priced based on estimated costs of providing the contractual goods or services. We account for a contract when the parties have approved the contract and are committed to perform on it, the rights of each party and the payment terms are identified, the contract has commercial substance, and it is probable that we will collect substantially all of the consideration. At contract inception, the Company determines whether the goods or services to be provided are to be accounted for as a single performance obligation or as multiple performance obligations. This evaluation requires professional judgment and it may impact the timing and pattern of revenue recognition. If multiple performance obligations are identified, we generally use the cost plus a margin approach to determine the relative standalone selling price of each performance obligation. When determining the total transaction price, the Company identifies both fixed and variable consideration elements within the contract. Variable consideration includes any amount within the transaction price that is not fixed, such as: award or incentive fees; performance penalties; unfunded contract value; or other similar items. For our contracts with award or incentive fees, the Company estimates the total amount of award or incentive fee expected to be recognized into revenue. Throughout the performance period, we recognize as revenue a constrained amount of variable consideration only to the extent that it is probable that a significant reversal of the cumulative amount recognized to date will not be required in a subsequent period. Our estimate of variable consideration is periodically adjusted based on significant changes in relevant facts and circumstances. In the period in which we can calculate the final amount of award or incentive fee earned - based on the receipt of the customer’s final performance score or determining that more objective, contractually-defined criteria have been fully satisfied - the Company will adjust our cumulative revenue recognized to date on the contract. This adjustment to revenue will be disclosed as the amount of revenue recognized in the current period for a previously satisfied performance obligation. We generally recognize revenue over time throughout the performance period as the customer simultaneously receives and consumes the benefits provided on our services-type revenue arrangements. This continuous transfer of control for our U.S. government contracts is supported by the unilateral right of our customer to terminate the contract for a variety of reasons without having to provide justification for its decision. For our services-type revenue arrangements in which there are a repetitive amount of services that are substantially the same from one month to the next, the Company applies the series guidance. We use a variety of input and output methods that approximate the progress towards complete satisfaction of the performance obligation, including: costs incurred, labor hours expended, and time-elapsed measures for our fixed-price stand ready obligations. For certain contracts, primarily our cost-plus and T&M services-type revenue arrangements, we apply the right-to-invoice practical expedient in which revenue is recognized in direct proportion to our present right to consideration for progress towards the complete satisfaction of the performance obligation. When a performance obligation has a significant degree of interrelation or interdependence between one month’s deliverables and the next, when there is an award or incentive fee, or when there is a significant degree of customization or modification, the Company generally records revenue using a percentage of completion method. For these revenue arrangements, substantially all revenue is recognized over time using a cost-to-cost input method based on the ratio of costs incurred to date to total estimated costs at completion. When estimates of total costs to be incurred on a contract exceed total revenue, a provision for the entire loss on the contract is recorded in the period in which the loss is determined. Contract modifications are reviewed to determine whether they should be accounted for as part of the original performance obligation or as a separate contract. When a contract modification changes the scope or price and the additional performance obligations are at their standalone selling price, the original contract is terminated and the Company accounts for the change prospectively when the new goods or services to be transferred are distinct from those already provided. When the contract modification includes goods or services that are not distinct from those already provided, the Company records a cumulative adjustment to revenue based on a remeasurement of progress towards the complete satisfaction of the not yet fully delivered performance obligation. Based on the critical nature of our contractual performance obligations, the Company may proceed with work based on customer direction prior to the completion and signing of formal contract documents. The Company has a formal review process for approving any such work that considers previous experiences with the customer, communications with the customer regarding funding status, and our knowledge of available funding for the contract or program. Costs of Revenue Costs of revenue includes all direct contract costs such as labor, materials, subcontractor costs, and indirect costs that are allowable and allocable to contracts under federal procurement standards. Costs of revenue also includes expenses that are unallowable under applicable procurement standards and are not allocable to contracts for billing purposes. Such unallowable expenses do not directly generate revenue but are necessary for business operations. Accounts Receivable and Allowance for Doubtful Accounts Accounts receivable are recorded at amounts earned less an allowance for doubtful accounts. The Company periodically reassesses its allowance for doubtful accounts by analyzing reasonably available information as of the balance sheet date, including the length of time that the receivable has been outstanding, historical bad debts and aging trends, and other general and contract specific factors. Upon determination that a specific receivable is uncollectible, the receivable is written off against the allowance for doubtful accounts reserve. Contract Assets Contract assets include unbilled receivables in which our right to consideration is conditional on factors other than the passage of time. Contract assets exclude billed and billable receivables. In addition, the costs to fulfill and obtain a contract are considered for capitalization based on contract specific facts and circumstances. The incremental costs to fulfill a contract (e.g., ramp up costs at the beginning of the period of performance) may be capitalized when expenses are incurred prior to satisfying a performance obligation. The incremental costs of obtaining a contract (e.g., sales commissions) are capitalized as an asset when the Company expects to recover them either directly or indirectly through the revenue arrangement’s profit margins. These capitalized costs are subsequently expensed over the revenue arrangement’s period of performance. The Company has elected to apply the practical expedient to immediately expense the costs to obtain a contract when the performance obligation will be completed within twelve months of contract inception. Contract assets are periodically reassessed based on reasonably available information as of the balance sheet date to ensure they do not exceed their net realizable value. Contract Liabilities Contract liabilities primarily include advance payments received from a customer in excess of revenue that may be recognized as of the balance sheet date. The advance payment is subsequently recognized into revenue as the performance obligation is satisfied. Remaining Performance Obligations The Company’s remaining performance obligations balance represents the expected revenue to be recognized for the satisfaction of remaining performance obligations on our existing contracts as of period end. The remaining performance obligations balance excludes unexercised contract option years and task orders that may be issued underneath an Indefinite Delivery/Indefinite Quantity (IDIQ) vehicle until such task orders are issued. The remaining performance obligations balance generally increases with the execution of new contracts and converts into revenue as our contractual performance obligations are satisfied. The Company continues to monitor our remaining performance obligations balance as it is subject to change from execution of new contracts, contract modifications or extensions, government deobligations, or early terminations. Based on this analysis, an adjustment to the period end balance may be required. Cash and Cash Equivalents The Company considers all investments with an original maturity of three months or less on their trade date to be cash equivalents. The Company classifies investments with an original maturity of more than three months but less than twelve months on their trade date as short-term marketable securities. Accounting for Business Combinations and Goodwill The purchase price of an acquired business is allocated to the tangible assets and separately identifiable intangible assets acquired less liabilities assumed based upon their respective fair values, with the excess recorded as goodwill. Determining the fair value of the acquired intangibles requires significant judgment in selecting underlying assumptions, including projected revenue growth rates, profit margins, and discount rates. In some cases, the Company uses discounted cash flow analyses, which were based on our best estimate of future sales, earnings and cash flows after considering such factors as general market conditions, customer budgets, existing firm and future orders, changes in working capital, long-term business plans and recent operating performance. Use of different estimates and judgments could yield materially different results. The Company evaluates goodwill at least annually for impairment, or whenever events or circumstances indicate that the carrying value may not be recoverable. The evaluation includes comparing the fair value of the relevant reporting unit to the carrying value, including goodwill, of such unit. The level at which the Company tests goodwill for impairment requires management to determine whether the operations below the operating segments constitute a self-sustaining business for which discrete financial information is available and segment management regularly reviews the operating results. If the fair value exceeds the carrying value, no impairment loss is recognized. However, if the carrying value of the reporting unit exceeds its fair value, the goodwill of the reporting unit may be impaired. Impairment is measured by comparing the implied fair value of the goodwill to its carrying value. Separately identifiable intangible assets with estimable useful lives are amortized over their respective estimated useful lives to their estimated residual values, and reviewed for impairment if impairment indicators are present. As part of the annual assessment, the Company estimates the fair value of its reporting units using both an income approach and a market approach. The valuation process considers management’s estimates of the future operating performance of each reporting unit. Companies in similar industries are researched and analyzed and management considers the domestic and international economic and financial market conditions, both in general and specific to the industry in which the Company operates, prevailing as of the valuation date. The income approach utilizes discounted cash flows. The Company calculates a weighted average cost of capital for each reporting unit in order to estimate the discounted cash flows. The Company evaluates goodwill as of the first day of the fiscal fourth quarter. In addition, the Company will perform interim impairment testing should circumstances requiring it arise. The Company completed its annual goodwill assessment as of April 1, 2021 and no impairment charge was necessary as a result of this assessment. Leases The Company enters into contractual arrangements primarily for the use of real estate facilities, information technology equipment, and certain other equipment. These arrangements contain a lease when the Company controls the underlying asset and has the right to obtain substantially all of the economic benefits or outputs from the asset. All of our leases are operating leases. The Company records a right of use (ROU) asset and lease liability as of the lease commencement date equal to the present value of the remaining lease payments. Most of our leases do not provide an implicit rate that can be readily determined. Therefore, we use a discount rate based on the Company’s incremental borrowing rate, which is determined using our credit rating and information available as of the commencement date. The ROU asset is then adjusted for initial direct costs and certain lease incentives included in the contractual arrangement. The Company has elected to not apply the lease recognition guidance for short-term equipment leases and to separate lease from non-lease components. Our operating lease arrangements may contain options to extend the lease term or for early termination. We account for these options when it is reasonably certain we will exercise them. ROU assets are evaluated for impairment in a manner consistent with the treatment of other long-lived assets. Operating lease expense is recognized on a straight-line basis over the lease term and is recorded primarily within indirect costs and selling expenses on the consolidated statement of operations. Variable lease expenses are generally recorded in the period they are incurred and are excluded from the ROU asset and lease liability. Long-Lived Assets (Excluding Goodwill) Long-lived assets such as property and equipment and intangible assets subject to amortization are reviewed for impairment whenever events or circumstances indicate that the carrying amount of an asset may not be fully recoverable. An impairment loss would be recognized if the sum of the long-term undiscounted cash flows is less than the carrying amount of the long-lived asset being evaluated. Any write-downs are treated as permanent reductions in the carrying amount of the assets. Property and equipment is recorded at cost. Depreciation of equipment and furniture has been provided over the estimated useful life of the respective assets (ranging from three to eight years) using the straight-line method. Leasehold improvements are generally amortized using the straight-line method over the remaining lease term or the useful life of the improvements, whichever is shorter. Repairs and maintenance costs are expensed as incurred. Separately identifiable definite-lived intangible assets are amortized over their respective estimated useful lives. External Software Development Costs Costs incurred in creating a software product to be sold or licensed for external use are expensed as incurred until technological feasibility has been established. Technological feasibility is established upon completion of a detailed program design or, in its absence, completion of a working model. Thereafter, all such software development costs are capitalized and subsequently reported at the lower of unamortized cost or estimated net realizable value. Capitalized costs are amortized on a straight-line basis over the remaining estimated economic life of the product. Supplemental Retirement Savings Plan The Company maintains the CACI International Inc Group Executive Retirement Plan (the Supplemental Savings Plan) and maintains the underlying assets in a Rabbi Trust. The Supplemental Savings Plan is a non-qualified defined contribution supplemental retirement savings plan for certain key employees whereby participants may elect to defer and contribute a portion of their compensation, as permitted by the plan. Each participant directs his or her investments in the Supplemental Savings Plan (see Note 21). A Rabbi Trust is a grantor trust established to fund compensation for a select group of management. The assets of this trust are available to satisfy the claims of general creditors in the event of bankruptcy of the Company. The assets held by the Rabbi Trust are invested in corporate owned life insurance (COLI) products. The COLI products are recorded at cash surrender value in the consolidated financial statements as supplemental retirement savings plan assets. The amounts due to participants are based on contributions, participant investment elections, and other participant activity and are recorded as supplemental retirement savings plan obligations. Income Taxes Income taxes are accounted for using the asset and liability method whereby deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the consolidated financial statement carrying amounts of assets and liabilities, and their respective tax bases, and operating loss and tax credit carry forwards. The Company accounts for tax contingencies in accordance with ASC 740-10-25, Income Taxes – Recognition Costs of Acquisitions Costs associated with legal, financial and other professional advisors related to acquisitions, whether successful or unsuccessful, are expensed as incurred. Foreign Currency Translation The assets and liabilities of the Company’s foreign subsidiaries whose functional currency is other than the U.S. dollar are translated at the exchange rate in effect on the reporting date, and income and expenses are translated at the weighted-average exchange rate during the period. The Company’s primary practice is to negotiate contracts in the same currency in which the predominant expenses are incurred, thereby mitigating the exposure to foreign currency fluctuations. The net translation gains and losses are not included in net income, but are accumulated as a separate component of shareholders’ equity. Foreign currency transaction gains and losses are recorded as incurred in indirect costs and selling expenses in the accompanying consolidated statements of operations. Earnings Per Share Basic earnings per share excludes dilution and is computed by dividing income by the weighted average number of common shares outstanding for the period. Diluted earnings per share reflects potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock but not securities that are anti-dilutive, including stock options and stock settled stock appreciation rights (SSARs) with an exercise price greater than the average market price of the Company’s common stock. Using the treasury stock method, diluted earnings per share includes the incremental effect of SSARs, stock options, restricted shares, and those restricted stock units (RSUs) that are no longer subject to a market or performance condition. Information about the weighted-average number of basic and diluted shares is presented in Note 24. Fair Value of Financial Instruments The carrying amounts of cash and cash equivalents, accounts receivable, accounts payable and amounts included in other current assets and current liabilities that meet the definition of a financial instrument approximate fair value because of the short-term nature of these amounts. The fair value of the Company’s debt under its bank credit facility approximates its carrying value at June 30, 2021. The fair value of the Company’s debt under its bank credit facility was estimated using Level 2 inputs based on market data on companies with a corporate rating similar to CACI’s that have recently priced credit facilities. Concentrations of Credit Risk Financial instruments that potentially subject the Company to credit risk include accounts receivable and cash equivalents. Management believes that credit risk related to the Company’s accounts receivable is limited due to a large number of customers in differing segments and agencies of the U.S. government. Accounts receivable credit risk is also limited due to the credit worthiness of the U.S. government. Management believes the credit risk associated with the Company’s cash equivalents is limited due to the credit worthiness of the obligors of the investments underlying the cash equivalents. In addition, although the Company maintains cash balances at financial institutions that exceed federally insured limits, these balances are placed with high quality financial institutions. Accounting for Sales of Financial Assets The Company accounts for receivable transfers under its Master Accounts Receivable Purchase Agreement (MARPA) as sales under ASC 860, Transfers and Servicing Other Comprehensive Income (Loss) Comprehensive income is the change in equity of a business enterprise during a period from transactions and other events and circumstances from non-owner sources. Other comprehensive income (loss) refers to revenue, expenses, and gains and losses that under U.S. GAAP are included in comprehensive income, but excluded from the determination of net income. The elements within other comprehensive income consist of foreign currency translation adjustments; the changes in the fair value of interest rate swap agreements, net of tax of $4.5 million, $8.7 million and $6.4 million for the years ended June 30, 2021, 2020 and 2019, respectively; and differences between actual amounts and estimates based on actuarial assumptions and the effect of changes in actuarial assumptions made under the Company’s post-retirement benefit plans, net of tax (see Note 17). As of June 30, 2021 and 2020, accumulated other comprehensive loss included a loss of $15.9 million and $38.6 million, respectively, related to foreign currency translation adjustments, a loss of $20.5 million and $33.2 million, respectively, related to the fair value of its interest rate swap agreements, and a gain of $0.1 million and a loss of $0.5 million, respectively, related to unrecognized post-retirement costs. Commitments and Contingencies The Company is involved in various lawsuits, claims, and administrative proceedings arising in the normal course of business. Management is of the opinion that any liability or loss associated with such matters, either individually or in the aggregate, will not have a material adverse effect on the Company’s operations and liquidity. Liabilities for loss contingencies arising from claims, assessments, litigation, fines and penalties and other sources are recorded when it is probable that a liability has been incurred and the amount of the assessment and/or remediation can be reasonably estimated.

RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS	NOTE 3. RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS Accounting Standards Updates Issued but Not Yet Adopted In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. This ASU provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships and other transactions that reference the London Interbank Offered Rate (LIBOR) or another reference rate expected to be discontinued because of reference rate reform. The guidance in this ASU is optional and expedients may be elected over time through December 31, 2022, as reference rate reform activities occur. During the fourth quarter of FY2020, CACI elected to apply the hedge accounting expedients related to probability and the assessments of effectiveness for future LIBOR-indexed cash flows to assume that the index upon which future hedged transactions will be based matches the index on the corresponding derivatives consistent with past presentation. Application of these expedients assisted in preserving the Company's presentation of derivatives as qualifying cash flow hedges. The Company continues to evaluate this guidance and may apply other elections, as applicable, as additional changes in the market occur . Accounting Standards Updates Adopted In August 2018, the Financial Accounting standards Board (FASB) issued Accounting standards update (ASU) 2018-15, Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses,

For these revenue arrangements, revenue is recognized over time primarily using a cost-to-cost input method based on the ratio of costs incurred to date to total estimated costs at completion. The EAC process requires the Company to use professional judgment when assessing risks, estimating contract revenue and costs, estimating variable consideration, and making assumptions for schedule and technical issues. The Company periodically reassesses its EAC assumptions and updates its estimates as needed. When estimates of total costs to be incurred on a contract exceed total revenue, a provision for the entire loss on the contract is recorded in the period in which the loss is determined. Based on changes in a contract’s EAC, a cumulative adjustment to revenue will be recorded. For the twelve months June 30, 2021 and 2020, we recognized an increase to income before income taxes of $44.1 million ($1.30 per diluted share) and $33.0 million ($0.95 per diluted share), respectively. The Company used its statutory tax rate when calculating the impact to diluted earnings per share. Revenue recognized from previously satisfied performance obligations was $2.5 million for the twelve months ended June 30, 2021, compared with $10.5 million for the twelve months ended June 30, 2020. The change in revenue generally relates to final true-up adjustments to our estimated award or incentive fees in the period in which we receive the customer’s final performance score or when we can determine that more objective, contractually-defined criteria have been fully satisfied. During the twelve months ended June 30, 2020, the Company received notification that certain contract close out risks had been mitigated on previously satisfied performance obligations and therefore recorded a reduction to its established reserve amount. Remaining Performance Obligations The Company’s remaining performance obligations balance as of period end represents the expected revenue to be recognized for the satisfaction of remaining performance obligations on our existing contracts. This balance excludes unexercised contract option years and task orders that may be issued underneath an IDIQ vehicle. Our remaining performance obligations balance as of June 30, 2021 was $6.9 billion. The Company expects to recognize approximately 85 percent of our remaining performance obligations balance as revenue over the next year and the remaining 15 percent thereafter

The Revolving Facility has sub-facilities of $100.0 million for same-day swing line loan borrowings and $25.0 million for stand-by letters of credit. At any time and so long as no default has occurred, the Company has the right to increase the Revolving Facility or the Term Loan in an aggregate principal amount of up to the greater of $500.0 million or an amount subject to 3.50 times senior secured leverage, calculated assuming the Revolving Facility is fully drawn, with applicable lender approvals. The Credit Facility is available to refinance existing indebtedness and for general corporate purposes, including working capital expenses and capital expenditures. The Revolving Facility is a secured facility that permits continuously renewable borrowings of up to $1,500.0 million. As of June 30, 2021, the Company had $945.0 million outstanding under the Revolving Facility and no borrowings on the swing line. The Company pays a quarterly facility fee for the unused portion of the Revolving Facility. The Term Loan is a five-year The interest rates applicable to loans under the Credit Facility are floating interest rates that, at the Company’s option, equal a base rate or a Eurodollar rate plus, in each case, an applicable rate based upon the Company’s consolidated total leverage ratio. As of June 30, 2021, the effective interest rate, including the impact of the Company’s floating-to-fixed interest rate swap agreements and excluding the effect of amortization of debt financing costs, for the outstanding borrowings under the Credit Facility was 2.33 percent. The Credit Facility requires the Company to comply with certain financial covenants, including a maximum total leverage ratio and a minimum interest coverage ratio. The Credit Facility also includes customary negative covenants restricting or limiting the Company’s ability to guarantee or incur additional indebtedness, grant liens or other security interests to third parties, make loans or investments, transfer assets, declare dividends or redeem or repurchase capital stock or make other distributions, prepay subordinated indebtedness and engage in mergers, acquisitions or other business combinations, in each case except as expressly permitted under the Credit Facility.

The swaps mature at various dates through 2026. The Company has designated the swaps as cash flow hedges. Unrealized gains are recognized as assets while unrealized losses are recognized as liabilities. The interest rate swap agreements are highly correlated to the changes in interest rates to which the Company is exposed. Realized gains and losses in connection with each required interest payment are reclassified from accumulated other comprehensive income or loss to interest expense.

OTHER COMMITMENTS AND CONTINGENCIES	NOTE 19. OTHER COMMITMENTS AND CONTINGENCIES General Legal Matters The Company is involved in various lawsuits, claims, and administrative proceedings arising in the normal course of business. Management is of the opinion that any liability or loss associated with such matters, either individually or in the aggregate, will not have a material adverse effect on the Company’s operations and liquidity. Government Contracting Payments to the Company on cost-plus-fee and T&M contracts are subject to adjustment upon audit by the Defense Contract Audit Agency (DCAA) and other government agencies that do not utilize DCAA’s services. The DCAA has completed audits of the Company’s annual incurred cost proposals through fiscal year 2019. We are still negotiating the results of prior years’ audits with the respective cognizant contracting officers and believe our reserves for such are adequate. In the opinion of management, adjustments that may result from these audits and the audits not yet started are not expected to have a material effect on the Company’s financial position, results of operations, or cash flows as the Company has accrued its best estimate of potential disallowances. Additionally, the DCAA continually reviews the cost accounting and other practices of government contractors, including the Company. In the course of those reviews, cost accounting and other issues are identified, discussed and settled.

Income Tax Disclosure [Abstract]
INCOME TAXES	NOTE 20. INCOME TAXES The Company changed its method of accounting related to the capitalization of property and equipment for its FY2020 U.S. federal income tax return (filed in the fourth quarter of FY2021), increasing its taxable income. Subsequently, the Company made a related change in its method of accounting that will result in a net operating loss (NOL) on its FY2021 income tax returns. Pursuant to provisions under the CARES Act, the U.S. federal income tax NOL generated in FY2021 will be carried back to tax years when the U.S. federal statutory income tax rate was greater than the current 21.0 percent. As a result of these method changes, in the fourth quarter of FY2021 the Company recorded a $56.2 million dollar income tax benefit and an income tax receivable of $232.6 million, which is included within prepaid expenses and other current assets on the accompanying consolidated balance sheet. The domestic and foreign components of income before provision for income taxes are as follows (in thousands): Year Ended June 30, 2021 2020 2019 Domestic $ 471,711 $ 379,414 $ 308,922 Foreign 27,904 22,223 18,987 Income before income taxes $ 499,615 $ 401,637 $ 327,909 The components of income tax expense are as follows (in thousands): Year Ended June 30, 2021 2020 2019 Current: Federal $ (94,143 ) $ 42,268 $ 41,675 State and local 19,958 14,744 17,606 Foreign 7,384 5,271 4,033 Total current (66,801 ) 62,283 63,314 Deferred: Federal 109,157 12,940 (27 ) State and local 185 5,465 (877 ) Foreign (369 ) (531 ) (105 ) Total deferred 108,973 17,874 (1,009 ) Total income tax expense $ 42,172 $ 80,157 $ 62,305 Income tax expense differs from the amounts computed by applying the U.S. federal statutory income tax rate of 21.0 percent as a result of the following (in thousands): Year Ended June 30, 2021 2020 2019 Expected tax expense computed at federal statutory rate $ 104,919 $ 84,344 $ 68,861 State and local taxes, net of federal benefit 21,252 15,965 13,216 Remeasurement of current year NOL (56,192 ) — — Nonincludible and nondeductible items, net (2,269 ) 3,133 1,971 Remeasurement of deferred taxes and transition tax — — (2,182 ) Effect of foreign tax rates (687 ) (377 ) (380 ) R&D tax credit, net (18,173 ) (10,700 ) (6,755 ) Other tax credits (648 ) (1,183 ) (2,138 ) Stock-based compensation (5,525 ) (10,900 ) (7,493 ) Other (505 ) (125 ) (2,795 ) Total income tax expense $ 42,172 $ 80,157 $ 62,305 Effective income tax rate 8.4 % 20.0 % 19.0 % The effective income tax rate in FY2021, FY2020, and FY2019, was 8.4 percent, 20.0 percent, and 19.0 percent, respectively. The effective income tax rate decreased in FY2021 primarily as a result of the $56.2 million benefit related to the carryback of the federal income tax NOL under the CARES Act, as well as an increase in research and development tax credits for past and current year returns. The tax effects of temporary differences that give rise to deferred taxes are presented below (in thousands): June 30, 2021 2020 Deferred tax assets: Deferred compensation and post-retirement obligations $ 36,183 $ 33,094 Reserves and accruals 58,900 41,137 Stock-based compensation 11,767 9,860 NOL carryforward 39,123 — Lease liability 110,282 99,539 Interest rate swaps 6,800 11,349 Other assets 2,757 6,786 Total deferred tax assets 265,812 201,765 Deferred tax liabilities: Goodwill and other intangible assets (291,282 ) (273,088 ) Unbilled revenue (35,115 ) (17,429 ) Prepaid expenses (8,932 ) (6,444 ) Right of use assets (90,186 ) (85,275 ) Property and equipment (167,527 ) (32,625 ) Total deferred tax liabilities (593,042 ) (414,861 ) Net deferred tax liability $ (327,230 ) $ (213,096 ) As discussed above, the FY2021 change in method of accounting will result in net operating losses on the Company’s FY2021 tax returns. For state tax purposes, the related losses will be carried forward, thus a NOL carryforward was recorded. The increase in the property and equipment deferred tax liability largely relates to the Company's changes in method of accounting and represents income to be recognized in future years The Company is subject to income taxes in the U.S. and various state and foreign jurisdictions. Tax statutes and regulations within each jurisdiction are subject to interpretation and require the application of significant judgment. The Company is currently under examination by the Internal Revenue Service for fiscal years 2017 through 2019. The Company does not expect the resolution of these examinations to have a material impact on its results of operations, financial condition or cash flows. U.S. income taxes have not been provided for undistributed earnings of foreign subsidiaries that have been permanently reinvested outside the United States. As of June 30, 2021, the estimated deferred tax liability associated with these undistributed earnings is approximately $1.9 million. Changes in the Company’s liability for unrecognized tax benefits is shown in the table below (in thousands): Year Ended June 30, 2021 2020 2019 Beginning of year $ 8,826 $ 1,530 $ 4,122 Additions based on current year tax positions 5,702 2,293 676 Lapse of statute of limitations — — (164 ) Additions based on prior year tax positions 20,025 5,003 — Reductions based on prior tax year positions — — (3,104 ) Settlement with taxing authorities (3,048 ) — — End of year $ 31,505 $ 8,826 $ 1,530 The Company’s total liability for unrecognized tax benefits as of June 30, 2021, 2020 and 2019 was approximately $ 31.5 million, $8.8 million and $1.5 million, respectively. During FY2021, the Company recognized an increase in reserves primarily related to current and prior year research and development tax credits. Any amount, if recognized, would positively impact the Company’s effective tax rate. The Company recognizes net interest and penalties as a component of income tax expense. Over the next 12 months, the Company does not expect a significant increase or decrease in the unrecognized tax benefits recorded at June 30, 2021. As of June 30, 2021, the entire balance of unrecognized tax benefits is included in other long-term liabilities.

STOCK PLANS AND STOCK-BASED COMPENSATION	NOTE 22. STOCK PLANS AND STOCK-BASED COMPENSATION Historically, the Company grants stock options, SSARs, non-performance-based RSUs and performance-based RSUs to key employees. Stock-based compensation expense is recognized on a straight-line basis ratably over the respective vesting periods. Performance-based RSUs are subject to achievement of a performance metric in addition to grantee service. Stock-based compensation expense for performance-based RSUs is recognized on an accelerated basis by treating each vesting tranche as if it was a separate grant. A summary of the components of stock-based compensation expense recognized during the years ended June 30, 2021, 2020, and 2019, together with the income tax benefits realized, is as follows (in thousands): Year Ended June 30, 2021 2020 2019 Stock-based compensation included in indirect costs and selling expense: Restricted stock and RSU expense $ 30,463 $ 29,302 $ 25,272 Income tax benefit recognized for stock-based compensation $ 8,009 $ 5,849 $ 4,865 The Company recognizes the effect of expected forfeitures of equity grants by estimating an expected forfeiture rate for grants of equity instruments. Amounts recognized for expected forfeitures are subsequently adjusted periodically and at major vesting dates to reflect actual forfeitures. The incremental income tax benefits realized upon the exercise or vesting of equity instruments are reported as operating cash flows. During the years ended June 30, 2021, 2020, and 2019, the Company recognized $7.3 million, $13.5 million, and $9.2 million of excess tax benefits, respectively, which have been reported as operating cash inflows in the accompanying consolidated statements of cash flows. Equity Grants and Valuation Under the terms of its 2016 Amended and Restated Incentive Compensation Plan (the 2016 Plan), the Company may issue, among others, non-qualified stock options, restricted stock, RSUs, SSARs, and performance awards, collectively referred to herein as equity instruments. The 2016 Plan was approved by the Company’s stockholders in November 2016 and amended and restated the 2006 Stock Incentive Plan (the 2006 Plan) which was due to expire at the end of the ten-year Annual grants under the 2016 Plan and the 2006 Plan are generally made to the Company’s key employees during the first quarter of the Company’s fiscal year and to members of the Company’s Board of Directors during the second quarter of the Company’s fiscal year. With the approval of its Chief Executive Officer, the Company also issues equity instruments to strategic new hires and to employees who have demonstrated superior performance. Upon the vesting of restricted shares and RSUs, the Company fulfills its obligations under the equity instrument agreements by either issuing new shares of authorized common stock or by issuing shares from treasury. The total number of shares authorized by shareholders for grants under the 2016 Plan and its predecessor plan was 1,200,000 plus any forfeitures from the 2006 Plan. The aggregate number of grants that may be made may exceed this approved amount as forfeited restricted stock and RSUs become available for future grants. As of June 30, 2021, cumulative grants of 1,062,994 equity instruments underlying the shares authorized have been awarded, and 221,277 of these instruments have been forfeited. The Company granted performance-based stock awards to key employees in October of 2020, 2019 and 2018. The final number of RSUs that are earned by participants and vest is based on the achievement of a specified EPS for the fiscal year and on the average share price for the 90-day period ended for the following three years. If the 90-day average share price of the Company’s stock in years one, two and three exceeds the 90-day average share price at the grant date by 100 percent or more the number of shares ultimately awarded could range up to 200 percent of the specified target award. In addition to the performance and market conditions, there is a service vesting condition that stipulates 50 percent of the award will vest 3 years from the grant date and 50 percent will vest approximately 4 years from the grant date, depending on the award date. The annual performance-based awards granted for each of the fiscal years presented were as follows: Performance-based stock awards granted Number of additional shares earned under performance-based stock awards Fiscal year 2021 111,729 — Fiscal year 2020 108,844 — Fiscal year 2019 129,108 12,462 We account for stock-based payments to employees, including grants of employee stock awards and purchases under employee stock purchase plans, in accordance with ASC 718, Compensation-Stock Compensation, We determine the fair value of our market-based and performance-based RSUs at the date of grant using generally accepted valuation techniques and the closing market price of our stock. The fair value for the annual grant made in October 2020 was determined using a Monte Carlo simulation model incorporating the following factors: 90-day average stock price at the grant date of $216.00 a share, risk free rate of return of 0.16 percent and expected volatility of 31.95 percent. Stock-based compensation cost is recognized as expense on an accelerated basis over the requisite service period for performance-based awards. The weighted-average fair value of RSUs granted during the years ended June 30, 2021, 2020, and 2019, was $243.87, $252.25, and $201.27, respectively. The Company also issues equity instruments in the form of RSUs under its Management Stock Purchase Plan (MSPP) and Director Stock Purchase Plan (DSPP). In addition, annual grants are made to members of the Company’s Board of Directors in the form of a set dollar value of RSUs. Grants to members of the Board of Directors vest based on the passage of time and continued service as a Director of the Company. Restricted shares and most non-performance-based RSUs generally vest in full three years from the date of grant. Changes in the number of unvested restricted stock and RSUs during each of the years in the three-year period ended June 30, 2021, 2020, and 2019, together with the corresponding weighted-average fair values, are as follows: Restricted Stock and Restricted Stock Units Number of Shares Weighted Average Grant Date Fair Value Unvested at June 30, 2018 663,987 $ 107.96 Granted 274,261 201.27 Vested (276,626 ) 61.85 Forfeited (32,816 ) 123.55 Unvested at June 30, 2019 628,806 $ 134.10 Granted 271,542 252.25 Vested (348,897 ) 77.33 Forfeited (49,528 ) 181.89 Unvested at June 30, 2020 501,923 $ 173.18 Granted 198,564 243.87 Vested (240,950 ) 99.55 Forfeited (33,566 ) 219.94 Unvested at June 30, 2021 425,971 $ 209.60 The total intrinsic value of RSUs that vested during the years ended June 30, 2021, 2020, and 2019 was $52.7 million, $79.6 million and $53.0 million, respectively, and the income tax benefit realized was $13.9 million, $15.9 million and $10.2 million, respectively. As of June 30, 2021, there was no unrecognized compensation cost related to SSARs and stock options and $38.6 million of unrecognized compensation cost related to restricted stock and RSUs scheduled to be recognized over a weighted-average period of 2.5 years. Stock Purchase Plans The Company adopted the 2002 Employee Stock Purchase Plan (ESPP), MSPP and DSPP in November 2002, and implemented these plans beginning July 1, 2003. There are 1,500,000, 500,000, and 75,000 shares authorized for grants under the ESPP, MSPP and DSPP, respectively. The ESPP allows eligible full-time employees to purchase shares of common stock at 95 percent of the fair market value of a share of common stock on the last day of the quarter. The maximum number of shares that an eligible employee can purchase during any quarter is equal to two times an amount determined as follows: 20 percent of such employee’s compensation over the quarter, divided by 95 percent of the fair market value of a share of common stock on the last day of the quarter. The ESPP is a qualified plan under Section 423 of the Internal Revenue Code and, for financial reporting purposes, was amended effective July 1, 2005 so as to be considered non-compensatory. Accordingly, there is no stock-based compensation expense associated with shares acquired under the ESPP. As of June 30, 2021, participants have purchased 1,258,062 shares under the ESPP, at a weighted-average price per share of $66.67. Of these shares, 40,658 were purchased by employees at a weighted-average price per share of $221.79 during the year ended June 30, 2021. During the year ended June 30, 2013, the Company established a 10b5-1 plan to facilitate the open market purchase of shares of Company stock to satisfy its obligations under the ESPP. The MSPP provides those senior executives with stock holding requirements a mechanism to receive RSUs in lieu of up to 100 percent of their annual bonus. For the fiscal years ended June 30, 2021, 2020, and 2019, RSUs awarded in lieu of bonuses earned were granted at 85 percent of the closing price of a share of the Company’s common stock on the date of the award, as reported by the New York Stock Exchange. RSUs granted under the MSPP vest at the earlier of 1) three-years Activity related to the MSPP during the year ended June 30, 2021 is as follows: MSPP RSUs outstanding, June 30, 2020 2,223 Granted 1,409 Issued (528 ) Forfeited (11 ) RSUs outstanding, June 30, 2021 3,093 Weighted average grant date fair value as adjusted for the applicable discount $ 185.45 The DSPP allows directors to elect to receive RSUs at the market price of the Company’s common stock on the date of the award in lieu of up to 100 percent of their annual retainer fees. Vested RSUs are settled in shares of common stock. There were no DSPP awards outstanding during the year ended June 30, 2021.

Fair Value Disclosures [Abstract]
FAIR VALUE OF FINANCIAL INSTRUMENTS	NOTE 23. FAIR VALUE OF FINANCIAL INSTRUMENTS ASC 820, Fair Value Measurements and Disclosures The Company’s financial assets and liabilities recorded at fair value on a recurring basis are categorized based on the priority of the inputs used to measure fair value. The inputs used in measuring fair value are categorized into three levels, as follows: • Level 1 Inputs – unadjusted quoted prices in active markets for identical assets or liabilities. • Level 2 Inputs – unadjusted quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets and liabilities in markets that are not active, inputs other than quoted prices that are observable, and inputs derived from or corroborated by observable market data. • Level 3 Inputs – amounts derived from valuation models in which unobservable inputs reflect the reporting entity’s own assumptions about the assumptions of market participants that would be used in pricing the asset or liability. The following table summarizes the financial assets and liabilities measured at fair value on a recurring basis as of June 30, 2021 and June 30, 2020, and the level they fall within the fair value hierarchy (in thousands): As of June 30, Financial Statement Fair Value 2021 2020 Description of Financial Instrument Classification Hierarchy Fair Value Interest rate swap agreements Other accrued expenses and current liabilities Level 2 $ 1,028 $ — Interest rate swap agreements Other long-term liabilities Level 2 $ 24,838 $ 43,168 The Company entered into interest rate swap agreements to manage its interest rate risk. The valuation of these instruments is determined using widely accepted valuation techniques including discounted cash flow analysis on the expected cash flows of each derivative. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves. To comply with the provisions of ASC 820, the Company incorporates credit valuation adjustments to appropriately reflect both its own nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements. Changes in the fair value of the interest rate swap agreements are recorded as a component of accumulated other comprehensive income or loss.

Disclosure Of Repurchase Agreements [Abstract]
ACCELERATED SHARE REPURCHASE	NOTE 26. ACCELERATED SHARE REPURCHASE On March 12, 2021, CACI entered into an accelerated share repurchase agreement (the “ASR Agreement”) with JPMorgan Chase Bank, National Association (JPMorgan). Under the ASR Agreement, we paid $500.0 million to JPMorgan and received an initial delivery of approximately 1.7 million shares of our common stock, which shares were recorded as a $400.0 million increase to treasury stock. The final number of shares to be repurchased will be based on the volume-weighted average stock price of our common stock during the term of the agreement, less a discount. This is evaluated as an unsettled forward contract indexed to our own stock, with $100.0 million classified within stockholders’ equity as additional paid-in-capital. The ASR Agreement is scheduled to settle prior to the end of the second quarter of FY2022. At final settlement, JPMorgan may be required to deliver additional shares of our common stock to us or, under certain circumstances, we may elect to make a cash payment or deliver shares of our common stock to JPMorgan.

SUMMARY OF SIGNIFICANT ACCOUN_2

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended
	Jun. 30, 2021
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying consolidated financial statements of the Company have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (SEC) and include the assets, liabilities, results of operations and cash flows for the Company, including its subsidiaries and ventures that are majority-owned or otherwise controlled by the Company. All intercompany balances and transactions have been eliminated in consolidation.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with generally accepted accounting principles in the United States (GAAP) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the consolidated financial statements, and the reported amounts of revenue and expenses during the reported periods. The most significant of these estimates and assumptions relate to estimating contract revenue and costs, measuring progress against the Company’s performance obligations, assessing the fair value of acquired assets and liabilities accounted for through business acquisitions, valuing and determining the amortization periods for long-lived intangible assets, assessing the recoverability of long-lived assets, reserves for accounts receivable, and reserves for contract related matters. Management evaluates its estimates on an ongoing basis using the most current and available information. However, actual results may differ significantly from estimates. Changes in estimates are recorded in the period in which they become known.
Revenue Recognition	Revenue Recognition The Company generates almost all of our revenue from three different types of contractual arrangements with the U.S. government: cost-plus-fee, fixed-price, and time-and-materials (T&M) contracts. Our contracts with the U.S. government are generally subject to the Federal Acquisition Regulation (FAR) and are competitively priced based on estimated costs of providing the contractual goods or services. We account for a contract when the parties have approved the contract and are committed to perform on it, the rights of each party and the payment terms are identified, the contract has commercial substance, and it is probable that we will collect substantially all of the consideration. At contract inception, the Company determines whether the goods or services to be provided are to be accounted for as a single performance obligation or as multiple performance obligations. This evaluation requires professional judgment and it may impact the timing and pattern of revenue recognition. If multiple performance obligations are identified, we generally use the cost plus a margin approach to determine the relative standalone selling price of each performance obligation. When determining the total transaction price, the Company identifies both fixed and variable consideration elements within the contract. Variable consideration includes any amount within the transaction price that is not fixed, such as: award or incentive fees; performance penalties; unfunded contract value; or other similar items. For our contracts with award or incentive fees, the Company estimates the total amount of award or incentive fee expected to be recognized into revenue. Throughout the performance period, we recognize as revenue a constrained amount of variable consideration only to the extent that it is probable that a significant reversal of the cumulative amount recognized to date will not be required in a subsequent period. Our estimate of variable consideration is periodically adjusted based on significant changes in relevant facts and circumstances. In the period in which we can calculate the final amount of award or incentive fee earned - based on the receipt of the customer’s final performance score or determining that more objective, contractually-defined criteria have been fully satisfied - the Company will adjust our cumulative revenue recognized to date on the contract. This adjustment to revenue will be disclosed as the amount of revenue recognized in the current period for a previously satisfied performance obligation. We generally recognize revenue over time throughout the performance period as the customer simultaneously receives and consumes the benefits provided on our services-type revenue arrangements. This continuous transfer of control for our U.S. government contracts is supported by the unilateral right of our customer to terminate the contract for a variety of reasons without having to provide justification for its decision. For our services-type revenue arrangements in which there are a repetitive amount of services that are substantially the same from one month to the next, the Company applies the series guidance. We use a variety of input and output methods that approximate the progress towards complete satisfaction of the performance obligation, including: costs incurred, labor hours expended, and time-elapsed measures for our fixed-price stand ready obligations. For certain contracts, primarily our cost-plus and T&M services-type revenue arrangements, we apply the right-to-invoice practical expedient in which revenue is recognized in direct proportion to our present right to consideration for progress towards the complete satisfaction of the performance obligation. When a performance obligation has a significant degree of interrelation or interdependence between one month’s deliverables and the next, when there is an award or incentive fee, or when there is a significant degree of customization or modification, the Company generally records revenue using a percentage of completion method. For these revenue arrangements, substantially all revenue is recognized over time using a cost-to-cost input method based on the ratio of costs incurred to date to total estimated costs at completion. When estimates of total costs to be incurred on a contract exceed total revenue, a provision for the entire loss on the contract is recorded in the period in which the loss is determined. Contract modifications are reviewed to determine whether they should be accounted for as part of the original performance obligation or as a separate contract. When a contract modification changes the scope or price and the additional performance obligations are at their standalone selling price, the original contract is terminated and the Company accounts for the change prospectively when the new goods or services to be transferred are distinct from those already provided. When the contract modification includes goods or services that are not distinct from those already provided, the Company records a cumulative adjustment to revenue based on a remeasurement of progress towards the complete satisfaction of the not yet fully delivered performance obligation. Based on the critical nature of our contractual performance obligations, the Company may proceed with work based on customer direction prior to the completion and signing of formal contract documents. The Company has a formal review process for approving any such work that considers previous experiences with the customer, communications with the customer regarding funding status, and our knowledge of available funding for the contract or program.
Costs of Revenue	Costs of Revenue Costs of revenue includes all direct contract costs such as labor, materials, subcontractor costs, and indirect costs that are allowable and allocable to contracts under federal procurement standards. Costs of revenue also includes expenses that are unallowable under applicable procurement standards and are not allocable to contracts for billing purposes. Such unallowable expenses do not directly generate revenue but are necessary for business operations.
Accounts Receivable and Allowance for Doubtful Accounts	Accounts Receivable and Allowance for Doubtful Accounts Accounts receivable are recorded at amounts earned less an allowance for doubtful accounts. The Company periodically reassesses its allowance for doubtful accounts by analyzing reasonably available information as of the balance sheet date, including the length of time that the receivable has been outstanding, historical bad debts and aging trends, and other general and contract specific factors. Upon determination that a specific receivable is uncollectible, the receivable is written off against the allowance for doubtful accounts reserve.
Contract Assets	Contract Assets Contract assets include unbilled receivables in which our right to consideration is conditional on factors other than the passage of time. Contract assets exclude billed and billable receivables. In addition, the costs to fulfill and obtain a contract are considered for capitalization based on contract specific facts and circumstances. The incremental costs to fulfill a contract (e.g., ramp up costs at the beginning of the period of performance) may be capitalized when expenses are incurred prior to satisfying a performance obligation. The incremental costs of obtaining a contract (e.g., sales commissions) are capitalized as an asset when the Company expects to recover them either directly or indirectly through the revenue arrangement’s profit margins. These capitalized costs are subsequently expensed over the revenue arrangement’s period of performance. The Company has elected to apply the practical expedient to immediately expense the costs to obtain a contract when the performance obligation will be completed within twelve months of contract inception. Contract assets are periodically reassessed based on reasonably available information as of the balance sheet date to ensure they do not exceed their net realizable value.
Contract Liabilities	Contract Liabilities Contract liabilities primarily include advance payments received from a customer in excess of revenue that may be recognized as of the balance sheet date. The advance payment is subsequently recognized into revenue as the performance obligation is satisfied.
Remaining Performance Obligations	Remaining Performance Obligations The Company’s remaining performance obligations balance represents the expected revenue to be recognized for the satisfaction of remaining performance obligations on our existing contracts as of period end. The remaining performance obligations balance excludes unexercised contract option years and task orders that may be issued underneath an Indefinite Delivery/Indefinite Quantity (IDIQ) vehicle until such task orders are issued. The remaining performance obligations balance generally increases with the execution of new contracts and converts into revenue as our contractual performance obligations are satisfied. The Company continues to monitor our remaining performance obligations balance as it is subject to change from execution of new contracts, contract modifications or extensions, government deobligations, or early terminations. Based on this analysis, an adjustment to the period end balance may be required.
Cash and Cash Equivalents	Cash and Cash Equivalents The Company considers all investments with an original maturity of three months or less on their trade date to be cash equivalents. The Company classifies investments with an original maturity of more than three months but less than twelve months on their trade date as short-term marketable securities.
Accounting for Business Combinations and Goodwill	Accounting for Business Combinations and Goodwill The purchase price of an acquired business is allocated to the tangible assets and separately identifiable intangible assets acquired less liabilities assumed based upon their respective fair values, with the excess recorded as goodwill. Determining the fair value of the acquired intangibles requires significant judgment in selecting underlying assumptions, including projected revenue growth rates, profit margins, and discount rates. In some cases, the Company uses discounted cash flow analyses, which were based on our best estimate of future sales, earnings and cash flows after considering such factors as general market conditions, customer budgets, existing firm and future orders, changes in working capital, long-term business plans and recent operating performance. Use of different estimates and judgments could yield materially different results. The Company evaluates goodwill at least annually for impairment, or whenever events or circumstances indicate that the carrying value may not be recoverable. The evaluation includes comparing the fair value of the relevant reporting unit to the carrying value, including goodwill, of such unit. The level at which the Company tests goodwill for impairment requires management to determine whether the operations below the operating segments constitute a self-sustaining business for which discrete financial information is available and segment management regularly reviews the operating results. If the fair value exceeds the carrying value, no impairment loss is recognized. However, if the carrying value of the reporting unit exceeds its fair value, the goodwill of the reporting unit may be impaired. Impairment is measured by comparing the implied fair value of the goodwill to its carrying value. Separately identifiable intangible assets with estimable useful lives are amortized over their respective estimated useful lives to their estimated residual values, and reviewed for impairment if impairment indicators are present. As part of the annual assessment, the Company estimates the fair value of its reporting units using both an income approach and a market approach. The valuation process considers management’s estimates of the future operating performance of each reporting unit. Companies in similar industries are researched and analyzed and management considers the domestic and international economic and financial market conditions, both in general and specific to the industry in which the Company operates, prevailing as of the valuation date. The income approach utilizes discounted cash flows. The Company calculates a weighted average cost of capital for each reporting unit in order to estimate the discounted cash flows. The Company evaluates goodwill as of the first day of the fiscal fourth quarter. In addition, the Company will perform interim impairment testing should circumstances requiring it arise. The Company completed its annual goodwill assessment as of April 1, 2021 and no impairment charge was necessary as a result of this assessment.
Leases	Leases The Company enters into contractual arrangements primarily for the use of real estate facilities, information technology equipment, and certain other equipment. These arrangements contain a lease when the Company controls the underlying asset and has the right to obtain substantially all of the economic benefits or outputs from the asset. All of our leases are operating leases. The Company records a right of use (ROU) asset and lease liability as of the lease commencement date equal to the present value of the remaining lease payments. Most of our leases do not provide an implicit rate that can be readily determined. Therefore, we use a discount rate based on the Company’s incremental borrowing rate, which is determined using our credit rating and information available as of the commencement date. The ROU asset is then adjusted for initial direct costs and certain lease incentives included in the contractual arrangement. The Company has elected to not apply the lease recognition guidance for short-term equipment leases and to separate lease from non-lease components. Our operating lease arrangements may contain options to extend the lease term or for early termination. We account for these options when it is reasonably certain we will exercise them. ROU assets are evaluated for impairment in a manner consistent with the treatment of other long-lived assets. Operating lease expense is recognized on a straight-line basis over the lease term and is recorded primarily within indirect costs and selling expenses on the consolidated statement of operations. Variable lease expenses are generally recorded in the period they are incurred and are excluded from the ROU asset and lease liability.
Long-Lived Assets (Excluding Goodwill)	Long-Lived Assets (Excluding Goodwill) Long-lived assets such as property and equipment and intangible assets subject to amortization are reviewed for impairment whenever events or circumstances indicate that the carrying amount of an asset may not be fully recoverable. An impairment loss would be recognized if the sum of the long-term undiscounted cash flows is less than the carrying amount of the long-lived asset being evaluated. Any write-downs are treated as permanent reductions in the carrying amount of the assets. Property and equipment is recorded at cost. Depreciation of equipment and furniture has been provided over the estimated useful life of the respective assets (ranging from three to eight years) using the straight-line method. Leasehold improvements are generally amortized using the straight-line method over the remaining lease term or the useful life of the improvements, whichever is shorter. Repairs and maintenance costs are expensed as incurred. Separately identifiable definite-lived intangible assets are amortized over their respective estimated useful lives.
External Software Development Costs	External Software Development Costs Costs incurred in creating a software product to be sold or licensed for external use are expensed as incurred until technological feasibility has been established. Technological feasibility is established upon completion of a detailed program design or, in its absence, completion of a working model. Thereafter, all such software development costs are capitalized and subsequently reported at the lower of unamortized cost or estimated net realizable value. Capitalized costs are amortized on a straight-line basis over the remaining estimated economic life of the product.
Supplemental Retirement Savings Plan	Supplemental Retirement Savings Plan The Company maintains the CACI International Inc Group Executive Retirement Plan (the Supplemental Savings Plan) and maintains the underlying assets in a Rabbi Trust. The Supplemental Savings Plan is a non-qualified defined contribution supplemental retirement savings plan for certain key employees whereby participants may elect to defer and contribute a portion of their compensation, as permitted by the plan. Each participant directs his or her investments in the Supplemental Savings Plan (see Note 21). A Rabbi Trust is a grantor trust established to fund compensation for a select group of management. The assets of this trust are available to satisfy the claims of general creditors in the event of bankruptcy of the Company. The assets held by the Rabbi Trust are invested in corporate owned life insurance (COLI) products. The COLI products are recorded at cash surrender value in the consolidated financial statements as supplemental retirement savings plan assets. The amounts due to participants are based on contributions, participant investment elections, and other participant activity and are recorded as supplemental retirement savings plan obligations.
Income Taxes	Income Taxes Income taxes are accounted for using the asset and liability method whereby deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the consolidated financial statement carrying amounts of assets and liabilities, and their respective tax bases, and operating loss and tax credit carry forwards. The Company accounts for tax contingencies in accordance with ASC 740-10-25, Income Taxes – Recognition
Costs of Acquisitions	Costs of Acquisitions Costs associated with legal, financial and other professional advisors related to acquisitions, whether successful or unsuccessful, are expensed as incurred.
Foreign Currency Translation	Foreign Currency Translation The assets and liabilities of the Company’s foreign subsidiaries whose functional currency is other than the U.S. dollar are translated at the exchange rate in effect on the reporting date, and income and expenses are translated at the weighted-average exchange rate during the period. The Company’s primary practice is to negotiate contracts in the same currency in which the predominant expenses are incurred, thereby mitigating the exposure to foreign currency fluctuations. The net translation gains and losses are not included in net income, but are accumulated as a separate component of shareholders’ equity. Foreign currency transaction gains and losses are recorded as incurred in indirect costs and selling expenses in the accompanying consolidated statements of operations.
Earnings Per Share	Earnings Per Share Basic earnings per share excludes dilution and is computed by dividing income by the weighted average number of common shares outstanding for the period. Diluted earnings per share reflects potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock but not securities that are anti-dilutive, including stock options and stock settled stock appreciation rights (SSARs) with an exercise price greater than the average market price of the Company’s common stock. Using the treasury stock method, diluted earnings per share includes the incremental effect of SSARs, stock options, restricted shares, and those restricted stock units (RSUs) that are no longer subject to a market or performance condition. Information about the weighted-average number of basic and diluted shares is presented in Note 24.
Fair Value of Financial Instruments	Fair Value of Financial Instruments The carrying amounts of cash and cash equivalents, accounts receivable, accounts payable and amounts included in other current assets and current liabilities that meet the definition of a financial instrument approximate fair value because of the short-term nature of these amounts. The fair value of the Company’s debt under its bank credit facility approximates its carrying value at June 30, 2021. The fair value of the Company’s debt under its bank credit facility was estimated using Level 2 inputs based on market data on companies with a corporate rating similar to CACI’s that have recently priced credit facilities.
Concentrations of Credit Risk	Concentrations of Credit Risk Financial instruments that potentially subject the Company to credit risk include accounts receivable and cash equivalents. Management believes that credit risk related to the Company’s accounts receivable is limited due to a large number of customers in differing segments and agencies of the U.S. government. Accounts receivable credit risk is also limited due to the credit worthiness of the U.S. government. Management believes the credit risk associated with the Company’s cash equivalents is limited due to the credit worthiness of the obligors of the investments underlying the cash equivalents. In addition, although the Company maintains cash balances at financial institutions that exceed federally insured limits, these balances are placed with high quality financial institutions.
Accounting for Sales of Financial Assets	Accounting for Sales of Financial Assets The Company accounts for receivable transfers under its Master Accounts Receivable Purchase Agreement (MARPA) as sales under ASC 860, Transfers and Servicing
Other Comprehensive Income (Loss)	Other Comprehensive Income (Loss) Comprehensive income is the change in equity of a business enterprise during a period from transactions and other events and circumstances from non-owner sources.

Commitments and Contingencies	Commitments and Contingencies The Company is involved in various lawsuits, claims, and administrative proceedings arising in the normal course of business. Management is of the opinion that any liability or loss associated with such matters, either individually or in the aggregate, will not have a material adverse effect on the Company’s operations and liquidity. Liabilities for loss contingencies arising from claims, assessments, litigation, fines and penalties and other sources are recorded when it is probable that a liability has been incurred and the amount of the assessment and/or remediation can be reasonably estimated.
RECENTLY ISSUED ACCOUNTING PRONOUNCEMENTS	Accounting Standards Updates Issued but Not Yet Adopted In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. This ASU provides optional expedients and exceptions for applying GAAP to contracts, hedging relationships and other transactions that reference the London Interbank Offered Rate (LIBOR) or another reference rate expected to be discontinued because of reference rate reform. The guidance in this ASU is optional and expedients may be elected over time through December 31, 2022, as reference rate reform activities occur. During the fourth quarter of FY2020, CACI elected to apply the hedge accounting expedients related to probability and the assessments of effectiveness for future LIBOR-indexed cash flows to assume that the index upon which future hedged transactions will be based matches the index on the corresponding derivatives consistent with past presentation. Application of these expedients assisted in preserving the Company's presentation of derivatives as qualifying cash flow hedges. The Company continues to evaluate this guidance and may apply other elections, as applicable, as additional changes in the market occur . Accounting Standards Updates Adopted In August 2018, the Financial Accounting standards Board (FASB) issued Accounting standards update (ASU) 2018-15, Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses,
