See Note 7 for details of the valuation of the derivative asset related to the redemption feature embedded in the MAA Series I preferred stock. Equity Forward Sale Agreements In August 2021, MAA entered into two 18-month forward sale agreements with respect to a total of 1.1 million shares of its common stock at an initial forward sale price of $190.56 per share, which is net of issuance costs. Under the forward sale agreements, the forward sale price was subject to adjustment on a daily basis based on a floating interest rate factor equal to a specified daily rate less a spread and was decreased based on amounts related to dividends on MAA’s common stock during the term of the forward sale agreements. No shares had been settled under the forward sale agreements as of December 31, 2022. In January 2023, MAA settled its two forward sale agreements with respect to a total of 1.1 million shares at a forward price per share of $185.23, which is inclusive of adjustments made to reflect the then-current federal funds rate, the amount of dividends paid to holders of MAA common stock and commissions paid to sales agents, for net proceeds of $203.7 million. The impact of the outstanding forward sales agreements was not dilutive to the Company’s diluted earnings per share for the three months ended March 31, 2022. At-the-Market Share Offering Program The Company has entered into an equity distribution agreement to establish an at-the-market, or ATM, share offering program, which allows MAA to sell shares of its common stock from time to time to or through its sales agents into the existing market at current market prices, and to enter into separate forward sales agreements to or through its forward purchasers. Under its ATM program, MAA has the authority to issue up to an aggregate of 4.0 million shares of its common stock, at such times to be determined by MAA. MAA has no obligation to issue shares through the ATM program. During the three months ended March 31, 2023 and 2022, MAA did no t sell any shares of common stock under its ATM program. As of March 31, 2023, 4.0 million shares remained issuable under the ATM program.
