We are also a lender under commercial loan agreements, which had an aggregate carrying value of approximately $850 million at December 31, 2023 and $1.9 billion at December 31, 2022. The decline in loan balances during 2023 was primarily attributable to prepayments and dispositions. These commercial loans are generally secured by real estate properties or by other assets and are individually evaluated for expected credit losses.
