Issuance of Senior Unsecured Notes
In January 2021, we issued $450.0 million of senior unsecured notes that bear a stated interest rate of 1.75%, have an effective interest rate of 1.83%, and mature on February 1, 2031. Proceeds from the unsecured notes offering were initially applied to pay down outstanding borrowings on the line of credit as of December 31, 2020, and we intend to allocate an amount equal to the net proceeds from the offering to the financing or refinancing of eligible green projects.
