We are party to an agreement with Seritage Growth Properties to provide a $2.0 billion term loan facility, which expires on July 31, 2023.

In the first quarter of 2020, we provided a loan to Lee Enterprises, Inc. in connection with its acquisition of our newspaper operations and the repayment of its then outstanding credit facilities. The loan balance at September 30, 2020 was $538 million. We are the sole lender to each of these entities and each of these loans is current as to payment status.
