INSPERITY, INC. 10-Q

Item 3. Quantitative and Qualitative Disclosures About Market Risk We are primarily exposed to market risks from fluctuations in interest rates and the effects of those fluctuations on the market values of our cash equivalent short-term investments, our available-for-sale marketable securities and our borrowings under our Facility, which bears interest at a variable market rate. As of March 31, 2025, we had outstanding letters of credit and borrowings totaling $370 million under the Facility. Please read Note 5 to the Consolidated Financial Statements, “ Long-Term Debt ,” for additional information. The cash equivalent short-term investments consist primarily of overnight investments, which are not significantly exposed to interest rate risk, except to the extent that changes in interest rates will ultimately affect the amount of interest income earned on these investments. Our available-for-sale marketable securities are subject to interest rate risk because these securities generally include a fixed interest rate. As a result, the market values of these securities are affected by changes in prevailing interest rates. We attempt to limit our exposure to interest rate risk primarily through diversification and low investment turnover. Our investment policy is designed to maximize after-tax interest income while preserving our principal investment. As a result, our marketable securities consist of primarily short-term U.S. Government Securities.
