Item 7A. Quantitative and Qualitative Disclosures about Market Risk

Interest Rate Risk

Our exposure to changes in interest rates is associated with borrowings under our Revolving Credit Facility and our Term Loan, both of which are variable-rate debt. At December 31, 2021, no amounts were outstanding under our Revolving Credit Facility. In May 2021, we entered into two interest rate swap agreements to effectively convert $480.0 million of our term loan borrowings from a variable rate to a fixed rate. These interest rate swaps are intended to mitigate the exposure to fluctuations in interest rates and qualify for hedge accounting treatment as cash flow hedges. A 100 basis point increase or decrease in interest rates relative to interest rates as of December 31, 2021 would decrease or increase our annual earnings, respectively, by approximately $0.2 million.

Market Price Sensitive Instruments

As of December 31, 2021, we had outstanding debt related to our convertible senior notes recorded on our consolidated balance sheet of $638.8 million, net of unamortized discount and issuance costs totaling $161.2 million. Changes in the fair value of our outstanding debt, which could be impacted by changes in interest rates, are not recorded in these consolidated financial statements as the debt is accounted for at cost less unamortized discount and issuance costs. The fair value of the convertible senior notes, which was $938.8 million as of December 31, 2021, is also impacted by changes in our stock price.

In order to reduce potential equity dilution, in connection with the issuance of the $800.0 million aggregate principal amount of 0.375% Notes, we entered into Capped Calls. We expect the Capped Calls to reduce the potential dilution to our common stock (or, in the event the conversion is settled in cash, to provide a source of cash to settle a portion of our cash payment obligation) in the event that at the time of conversion our stock price exceeds the conversion price under the 0.375% Notes. The Capped Calls have an initial strike price of $335.90 per share and cover 3.5 million shares of common stock.

Foreign Currency Exchange Risk

Foreign currency risk arises from our investments in subsidiaries owned and operated in non-U.S. countries. Such risk is also a result of transactions with customers in countries outside the United States. Approximately 33% of our revenue was denominated in foreign currencies for the year ended December 31, 2021. As our business in regions outside of the United States continues to increase, we will be increasingly exposed to foreign currency exchange risk related to our foreign operations. The cost of revenue related to revenue generated outside of the United States is primarily denominated in U.S. dollars; however, operating costs related to these revenues are largely denominated in the same respective currencies, thereby partially limiting our transaction risk exposure. Fluctuations in the rate of exchange between the United States dollar and foreign currencies, primarily the Euro, British Pound and Canadian Dollar, could adversely affect our financial results, including our revenues, revenue growth rates, gross margins, income and losses as well as assets and liabilities.

We have intercompany receivables and payables from our foreign subsidiaries that are denominated in foreign currencies, principally the Euro, the British pound and the Canadian dollar. Fluctuations from the beginning to the end of a reporting period result in the revaluation of our foreign currency-denominated intercompany receivables and payables, generating currency translation gains or losses. Net realized and unrealized gains (losses) from foreign currency transactions are included in other (expense) income, net in the consolidated statement of income and amounted to a loss of $2.0 million for the year ended December 31, 2021.
