Item 3. Quantitative and Qualitative Disclosures About Market Risk Impact of inflation. We believe that inflation has not had a material impact on our results of operations for the nine months ended September 30, 2021 or 2020. There can be no assurance that future inflation will not have an adverse impact on our operating results and financial condition. Market risk . As of September 30, 2021, we have no derivative financial instruments or derivative commodity instruments. We invest cash in excess of current operating requirements in money market instruments and commercial paper at multiple financial institutions. Interest rate risk . We manage interest rate risk by investing excess funds in cash equivalents, BBB or higher rated corporate bonds, commercial paper, municipal securities, asset backed securities, municipal bonds, and collateralized mortgage obligations bearing variable interest rates, which are tied to various market indices or individual bond coupon rates. Our future investment income may fall short of expectations due to changes in interest rates or we may suffer losses in principal if we are forced to sell securities before their maturity date that have declined in market value due to changes in interest rates. At September 30, 2021, a 10% increase or decrease in interest rates would not have a material impact on our future earnings, fair values, or cash flows. For information regarding our variable rate debt, see “Market risk” above.
