Foreign Currency Exchange Risk—We generate all of our revenue and incur all of our expenses in United States dollars. As a result, our financial results are not affected by changes in foreign currency exchange rates. Interest Rate Sensitivity—We pay interest on various types of debt instruments. The related debt agreements entail either fixed or variable interest rates. Instruments which have fixed rates are mainly leases, equipment promissory notes and leasehold improvements. Variable rate interest obligations relate primarily to amounts borrowed under our senior secured credit facilities. Accordingly, our interest expense and consequently, our earnings, are affected by changes in short-term interest rates. A hypothetical 1% increase in the adjusted SOFR rates under the Refinancing Term Loan would result in an increase of approximately $8.2 million in annual interest expense and a corresponding decrease in income before taxes.
