[1] As of December 31, 2022 and 2021, restricted cash consisted of proceeds from the sale of assets and proceeds from the sale of joint venture interests held as collateral pursuant to the agreement governing our former credit facility, or our credit agreement. In December 2023, we repaid all $450,000 outstanding under such secured credit facility with Wells Fargo Bank, National Association, as administrative agent and a lender, and a syndicate of other lenders, and then terminated our credit agreement in accordance with its terms and without penalty. As such, we are no longer required to hold any proceeds from the sale of properties as restricted cash. Restricted cash also consists of amounts escrowed for real estate taxes, insurance and capital expenditures at certain of our mortgaged properties.
