[1] We have a variable interest entity related to PPA V (see Note 10 - Portfolio Financings) and a joint venture in the Republic of Korea (see Note 16 - SK ecoplant Strategic Investment), which represent a portion of the consolidated balances recorded within these financial statement line items.In August 2023, we sold the PPA V entity as a result of the PPA V Repowering of Energy Servers (see Note 10 - Portfolio Financings), as such the consolidated balances recorded within these financial statement line items as of September 30, 2023 exclude PPA V balances.
