(1) On February 14, 2023, the Company entered into a Third Amendment to the Amended and Restated Senior Unsecured Credit Agreement (the "Amendment"). The Amendment provides, among other things, for (i) an increase in the aggregate amount of commitments under the Company's existing $600 million unsecured credit facility (the "Revolver") by $250 million (the “Increased Commitments”) to an aggregate amount of $850 million and (ii) the replacement of the interest reference rate for U.S. dollar-denominated borrowings under the Revolver from LIBOR to an adjusted Secured Overnight Financing Rate. The pricing and other terms applicable to the Increased Commitments are the same as those applicable to the existing revolving loan commitments that were in effect prior to the Amendment. Except as amended by the Amendment, the remaining terms of the unsecured credit facility remain in full force and effect.
