Potengi — In March 2022, Tucano Holding I (“Tucano”), a subsidiary of AES Brasil, issued new shares in the Potengi wind development project. BRF S.A. (“BRF”) acquired shares representing 24% of the equity in the project for $12 million, reducing the Company’s indirect ownership interest in Potengi to 35.5%. As the Company maintained control after the transaction, Potengi continues to be consolidated by the Company. As part of the transaction, BRF was given an option to sell its entire ownership interest at the conclusion of the PPA term. As a result, the minority ownership interest is considered temporary equity, which will be adjusted for earnings or losses allocated to the noncontrolling interest under ASC 810. Any subsequent changes in the redemption value of the exit rights will be recognized against permanent equity in accordance with ASC 480-10-S99, as it is probable that the shares will become redeemable.AES Clean Energy Development — On February 1, 2021, the Company substantially completed the merger of the sPower and AES Renewable Holdings 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.During the second quarter of 2021, the Company recorded measurement period adjustments to the estimated fair values of the sPower and AES Renewable Holdings development platforms and the value of the partnership rights initially recorded in the first quarter of 2021, which resulted in a $81 million increase in the value of the temporary equity. These measurement period adjustments primarily relate to higher expected developer profits and a higher growth rate, reflective of additional information that became available regarding market participants’ views of the value of early-stage renewable development projects as of the date of acquisition. The temporary equity will be adjusted for earnings or losses allocated to the noncontrolling interest under ASC 810. Any subsequent changes in the redemption value of the exit rights will be recognized against permanent equity in accordance with ASC 480-10-S99, as it is probable that the shares will become redeemable. See Note 18—Acquisitions for further information.11. EQUITY Equity UnitsIn March 2021, the Company issued 10,430,500 Equity Units with a total notional value of $1,043 million. Each Equity Unit has a stated amount of $100 and was initially issued as a Corporate Unit, consisting of a forward stock purchase contract (“2024 Purchase Contracts”) and a 10% undivided beneficial ownership interest in one share of 0% Series A Cumulative Perpetual Convertible Preferred Stock, issued without par and with a liquidation preference of $1,000 per share (“Series A Preferred Stock”). Upon reconsideration of the nature of the Equity Units, the Company re-evaluated its accounting assessment and concluded that the Equity Units should be accounted for as one unit of account based on the economic linkage between the 2024 Purchase Contracts and the Series A Preferred Stock, as well as the Company's assessment of the applicable accounting guidance relating to combining freestanding instruments. The Equity Units represent mandatorily convertible preferred stock. Accordingly, the shares associated with the combined instrument are reflected in diluted earnings per share using the if-converted method.In the fourth quarter of 2021, the Company also corrected the classification of certain amounts in the Consolidated Balance Sheet and Statement of Changes in Equity to reflect the 2024 Purchase Contracts and Series A Preferred Stock as one unit of account. The corrections have no impact on the Company's net earnings, total assets, cash flows, or segment information.
