(1)  During the year ended December 31, 2022, 65,279,851 shares were sold and 58,534,967 settled pursuant to forward sale confirmations. In addition, as of December 31, 2022, 6,744,884 shares of common stock subject to forward sale confirmations have been executed at a weighted average initial price of $63.31 per share but not settled. Upon settlement, subject to certain exceptions, we may elect, in our sole discretion, to cash settle or net share settle all or any portion of our obligations under any forward sale agreement, in which cases we may not receive any proceeds (in the case of cash settlement) or will not receive any proceeds (in the case of net share settlement), and we may owe cash (in the case of cash settlement) or shares of our common stock (in the case of net share settlement) to the relevant forward purchaser. We currently expect to fully physically settle any forward sale agreement with the respective forward purchaser on one or more dates specified by us on or prior to the maturity date of such forward sale agreement, in which case we expect to receive aggregate net cash proceeds at settlement equal to the number of shares specified in such forward sale agreement multiplied by the relevant forward price per share. We currently expect to fully settle the outstanding forward sale agreements during the three months ended March 31, 2023, representing $0.4 billion in net proceeds, for which the weighted average forward price at December 31, 2022 was $62.59 per share. Our forward sale confirmations are accounted for as equity instruments, as we have determined the agreements meet the derivatives and hedging guidance scope exception. No shares were sold pursuant to forward sale confirmations during years ended December 31, 2021 and 2020.
