Item 3. Quantitative and Qualitative Disclosures About Market Risk

Interest Rate Risk

The fair value of our long-term debt, all of which is fixed-rate debt, is subject to fluctuations resulting primarily from changes in market interest rates. The following table provides the fair value of our long-term debt and the change in fair value based on a 1% increase or decrease in market interest rates at June 30, 2023 and December 31, 2022:

We expect interest rates on borrowings under the Credit Agreement to be based on the Term Secured Overnight Financing Rate, plus a percentage based on the higher of the ratings of our long-term senior unsecured debt from Moody’s and S&P. The applicable percentage for borrowings under the Credit Agreement at June 30, 2023 was 1.0% based on our long-term senior unsecured debt ratings on that date. At June 30, 2023 and December 31, 2022, we had no borrowings under the Credit Agreement.
