Senior Unsecured Credit Facility

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 the London Interbank Offered Rate 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.

2023 Term Loan

On December 18, 2023, the Company entered into a $500 million unsecured term loan with a maturity date of December 16, 2024 (the "2023 Term Loan"), which has an optional one-year extension that can be requested by the Company prior to the initial maturity date. The extension option is subject to the consent of the lenders and certain customary conditions.

The 2023 Term Loan and all accrued but unpaid interest must be repaid in full on the maturity date. Upon the occurrence of certain debt issuances and equity issuances, as defined in the term loan agreement, the Company is required to make certain principal prepayments of the 2023 Term Loan in an amount equal to 100% of the net cash proceeds from those debt and equity issuances.

The Company may elect to have the 2023 Term Loan bear interest at a rate equal to (i) SOFR (subject to a credit spread adjustment of 0.10% and a 0.00% floor) plus a margin ranging from 125 to 175 basis points, or (ii) a base rate plus a margin ranging from 25 to 75 basis points. In each case, the margin is determined according to the Company’s senior unsecured long-term debt rating.

The term loan agreement requires that the Company comply with various covenants, including restrictions on liens, incurring indebtedness, making dividends, stock repurchases, investments, and completing mergers and/or asset sales. The term loan agreement has financial covenants which require the Company to maintain a consolidated fixed charge coverage ratio of at least 2.5 to 1.0, and a total leverage ratio of not more than 4.5 to 1.0 which may be increased to 5.5 to 1.0 for up to three consecutive fiscal quarters commencing with the fiscal quarter in which certain material acquisitions are consummated. As long as the Company maintains an Investment Grade Rating, as defined in the term loan agreement, then the Company will not need to comply with the consolidated fixed charge coverage ratio covenant.

The term loan agreement includes customary events of default, the occurrence of which, following any applicable cure period, would permit the lenders to, among other things, declare the principal, accrued interest, and other obligations of the Company under the term loan agreement to be immediately due and payable.

Economic Development Loans

The Company entered into economic development agreements with various governmental entities in conjunction with the relocation of its corporate headquarters in April 2013. In accordance with these agreements, the governmental entities agreed to advance approximately $4.4 million to the Company to offset a portion of the corporate headquarters relocation and tenant improvement costs in consideration of the employment of permanent, full-time employees within the jurisdictions. These advances bear interest at a rate of 3% per annum.

Repayment of the advances is contingent upon the Company achieving certain performance conditions. The performance conditions are measured annually on December 31st and primarily relate to maintaining certain levels of employment within the various jurisdictions. If the Company fails to meet an annual performance condition, then the Company may be required to repay a portion, or all, of the advances including accrued interest by April 30th following the measurement date. Any outstanding advances upon expiration of the Company's ten-year corporate headquarters lease agreement in 2023 will be forgiven in full. The $4.4 million of advances were included in debt in the consolidated balance sheets.

Upon the expiration of the Company's previous ten-year corporate headquarters lease agreement in 2023, the Company concluded that it had achieved the performance conditions over the entire term of the agreement and therefore, the Company is not required to repay the advances. As a result, during the year ended December 31, 2023, the Company derecognized the $4.4 million economic development loans debt from the consolidated balance sheets and recognized a gain on extinguishment of debt in the consolidated statements of income.
