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.
