We are also party to commercial loan agreements with Seritage Growth Properties (“Seritage”) and Lee Enterprises, Inc, (“Lee”), in which loan balances aggregated $1.9 billion at March 31, 2022 and 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 loan agreement with Seritage, as amended, allows optional loan prepayments without penalty and further provides Seritage with 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. The loan to Lee matures in 2045. The Lee loan agreement provides for mandatory principal prepayments under certain conditions and optional prepayments at par. We are the sole lender to each of these entities and each of these loans is current as to payment status.
