Subsequent Events	25. Subsequent Events Our significant events subsequent to December 31, 2020 were as follows: Secured Financing Agreements In January 2021, we entered into a Residential Loans repurchase facility to finance residential loans. The facility carries a one-year term, which we intend to extend every three months, and an annual interest rate of one-month LIBOR + 2.00% to 2.50% subject to a 25 bps LIBOR floor. The maximum facility size is $375.0 million. Collateralized Loan Obligations In February 2021, we priced STWD 2021-SIF1, a $500.0 million new issue CLO related to a pool of our infrastructure loans held-for-investment, with $410.0 million of third party financing at an average coupon of LIBOR + 181 bps. The CLO contains a reinvestment feature that, subject to certain eligibility criteria, allows us to contribute new loans or participation interests in loans to the CLO for a period of three years. The transaction is subject to customary closing conditions.
