Equity [Abstract]
STOCKHOLDERS' EQUITY	STOCKHOLDERS' EQUITYIn the third quarter of 2021, the Company entered into an Equity Distribution Agreement with six financial institutions known as an at-the-market stock offering program ("ATM program"), under which the Company may offer and sell shares of its common stock from time to time in "at-the-market" offerings with an aggregate gross sales price of up to $500 million. In connection with the ATM program, Cousins may, at its discretion, enter into forward equity sale agreements. The use of a forward equity sale agreement would allow the Company to lock in a share price on the sale of shares of its common stock at the time the agreement is executed, but defer receiving the proceeds from the sale of shares until a later date, allowing the Company to better align such funding with its capital needs. Sales of shares of Cousins' stock through its banking relationships, if any, are made in amounts and at times to be determined by Cousins from time to time, but the Company has no obligation to sell any of the shares in the offering and may suspend sales in connection with the offering at any time. Sales of Cousins' common stock under forward equity sale agreements, if undertaken, meet the derivatives and hedging guidance scope exception as the contracts are related to the Company's own stock. To date, the Company has sold 2.6 million shares under forward equity sale agreements, all of which were outstanding as of March 31, 2022, and are currently expected to settle by September 30, 2022 for proceeds of $104.0 million, net of $1.1 million of compensation to be paid with respect to such sales. The Company has not received proceeds related to these sales or the issuance of any shares under the ATM program. To the extent unsettled shares sold under forward equity sale agreements are potentially dilutive at period end under the treasury stock method, the impact of such dilution is disclosed in the calculation included in Note 13.
