We are also party to two commercial loan agreements with an aggregate carrying value of $1.7 billion at September 30, 2022 and $1.9 billion at December 31, 2021. The larger of these loans is with Seritage Growth Properties (“Seritage”), which had a carrying value of $1.27 billion as of September 30, 2022 and $1.44 billion as of December 31, 2021. The Seritage loan is pursuant to a $2.0 billion term loan facility and the outstanding loan is secured by mortgages on its real estate properties. The Seritage loan agreement allows optional loan prepayments without penalty and further provides the option to extend the maturity of the loan to July 31, 2025, if the outstanding principal has been reduced to $800 million by the original expiration date of July 31, 2023. Each of these loans is current as to payment status.
