Item 3. Quantitative and Qualitative Disclosures About Market Risk
We are subject to market risk primarily from exposure to changes in interest rates based on our financing, investing and cash management activities. We utilize a balanced mix of maturities along with both fixed rate and variable rate debt to manage our exposures to changes in interest rates. Additionally, we periodically enter into interest rate swap agreements to manage our exposure to interest rate fluctuations. Our interest rate swap agreements involve the exchange of fixed and variable rate interest payments between two parties, based on common notional principal amounts and maturity dates. The notional amounts of the swap agreements represent balances used to calculate the exchange of cash flows and are not our assets or liabilities. Our credit risk related to these agreements is considered low because the swap agreements are with creditworthy financial institutions. The interest payments under these agreements are settled on a net basis. These derivatives have been recognized in the financial statements at their respective fair values. Changes in the fair value of these derivatives, which are designated as cash flow hedges, are included in other comprehensive income.
Our variable rate debt instruments are primarily indexed to the prime rate or LIBOR. Interest rate changes would result in gains or losses in the market value of our fixed rate debt portfolio due to differences in market interest rates and the rates at the inception of the debt agreements. Based on our indebtedness and the effect of our interest rate swap agreements at March 31, 2021, a 100 basis point interest rate change would impact our net earnings and cash flow by approximately $3.4 million annually. Although there can be no assurances that interest rates will not change significantly, we do not expect changes in interest rates to have a material effect on our net earnings or cash flows in 2021 based on our indebtedness at March 31, 2021.
