Our floating rate debt under the 2024 Credit Facilities exposes us to interest rate risk. Interest rate risk results when the maturity or repricing intervals of interest-earning assets and interest-bearing liabilities are different. A change in the Federal Funds Rate, or the reference rate set by Bank of America, N.A., would have affected the rate at which we could borrow funds under the 2024 Credit Facilities. The balance outstanding under our 2024 Credit Facilities at June 30, 2026 was $1,473.5 million, of which $973.5 million was subject to interest rate risk. If market rates were to increase or decrease 100 basis points from the levels at June 30, 2026, interest expense would have increased or decreased approximately $9.7 million annually. We do not engage in trading market risk sensitive instruments. We periodically use interest rate swaps to manage interest rate risk exposure. The interest rate swaps effectively modify our exposure to interest rate risk, primarily through converting portions of our floating rate debt under the 2024 Credit Facilities to a fixed rate basis. These agreements involve the receipt or payment of floating rate amounts in exchange for fixed rate interest payments over the life of the agreements without an exchange of the underlying principal amounts. As of June 30, 2026, we had the following interest rate swaps outstanding (in thousands, except percentages): June 30, 2026 Notional Amount Fixed Rate Expiration Interest rate swap $ 100,000 4.047% 7/14/2026 Interest rate swap $ 30,000 1.186% 12/14/2026 Interest rate swap $ 100,000 3.850% 7/14/2027 Interest rate swap $ 20,000 2.450% 8/14/2027 Interest rate swap $ 25,000 3.669% 4/14/2028 Interest rate swap $ 25,000 4.488% 10/14/2028 Interest rate swap $ 50,000 3.703% 3/14/2030 Interest rate swap $ 50,000 3.503% 4/14/2030 Interest rate swap $ 50,000 3.658% 7/14/2030 Interest rate swap $ 50,000 3.680% 7/15/2030 Management will continue to evaluate the potential use of interest rate swaps as we deem appropriate under certain operating and market conditions. We do not enter into derivative instruments for trading or speculative purposes. 40 In connection with the services provided by our payroll operations, funds collected from our clients’ accounts in advance are segregated and may be invested in short-term investments, such as corporate and municipal bonds. In accordance with our investment policy, all investments carry an investment grade rating at the time of the initial acquisition, and are classified as available-for-sale securities. At each respective balance sheet date, these investments are adjusted to fair value with fair value adjustments being recorded to other comprehensive income or loss and reflected in the accompanying Condensed Consolidated Statements of Comprehensive Income for the respective period.
