_____________________________ (1)Characteristics of quotas are similar to common stock. AES Clean Energy Development — On February 1, 2021, the Company substantially completed the merger of the sPower and AES Distributed Energy development platforms to form AES Clean Energy Development, which will serve as the development vehicle for all future renewable projects in the U.S. As part of the transaction, AlMCo, our existing partner in the sPower equity method investment, received a 25% minority ownership interest in the newly formed entity along with certain partnership rights, though not currently in effect, that would enable AIMCo to exit in the future. As a result, the minority ownership interest is considered temporary equity. Any subsequent changes in the redemption value of the exit rights will be recognized in permanent equity. See Note 18—Acquisitions for further information.
