We are exposed to market risks in the ordinary course of our business. Market risk represents the risk of loss that may impact our financial position due to adverse changes in financial market prices and rates. Our market risk exposure is primarily the result of fluctuations in interest rates. Interest Rate Risk We are subject to interest rate risk in connection with our Amended Credit Agreement. Interest rate changes generally impact the amount of our interest payments and, therefore, our future net income and cash flows, assuming other factors held constant. Assuming the amounts outstanding under our Amended Credit Agreement are fully drawn, a hypothetical 10% change in interest rates would not have a material impact on our consolidated financial statements. Our cash and cash equivalents consist primarily of interest-bearing accounts. Such interest-earning instruments carry a degree of interest rate risk. To minimize interest rate risk in the future, we intend to maintain our portfolio of cash equivalents in a variety of investment-grade securities, which may include commercial paper, money market funds and government and non-government debt securities. Because of the short-term maturities of our cash, cash equivalents, and marketable securities, we do not believe that an increase in market rates would have any significant negative impact on the realized value of our investments.
