Item 7A. Quantitative and Qualitative Disclosure about Market Risk

We have operations within the U.S. and internationally, and we are exposed to market risks in the ordinary course of our business. These risks include primarily interest rate and foreign currency exchange risk.

Interest Rate Risk

We are exposed to market risk from changes in interest rates on our credit facility, which accrues interest at a variable rate. No amount was owed on our revolving credit facility as of December 31, 2020. We have not used any derivative financial instruments to manage our interest rate risk exposure. Based upon the short-term investment amount as of December 31, 2020, a hypothetical one percentage point increase or decrease in the interest rate would result in a corresponding increase or decrease in investment income of approximately $1.9 million annually.

Foreign Currency Exchange Risk

We have foreign currency risks related to our revenue and expenses denominated in currencies other than the U.S. Dollar, principally the Euro, British Pound, Australian Dollar, Canadian Dollar, Japanese Yen and Indonesian Rupiah. The volatility of exchange rates depends on many factors that we cannot forecast with reliable accuracy. We have experienced and will continue to experience fluctuations in our net income as a result of transaction gains and losses related to translating cash balances, trade accounts receivable and payable balances that are denominated in currencies other than the U.S. Dollar. The effect of an immediate 10% adverse change in foreign exchange rates on foreign-denominated accounts as of December 31, 2020, would result in a foreign currency loss of approximately $24.8 million. In the event our non-U.S. Dollar denominated sales and expenses increase, our operating results may be more greatly affected by fluctuations in the exchange rates of the currencies in which we do business.

We enter into forward contracts or other derivative transactions in an attempt to hedge our foreign currency risk. There can be no assurance that such transactions will be effective in hedging some or all of our foreign currency exposures and under some circumstances could generate losses for us.
