|IHS MARKIT LTD. filed this Form 10-K on 01/18/2019|
A hypothetical ten percent change in the currencies that we are primarily exposed to would have impacted our 2018 revenue by approximately $91 million and would not have had a material impact on operating income. Approximately 75% of total revenue was earned in subsidiaries with the U.S. dollar as the functional currency.
We are exposed to credit risk associated with cash equivalents, foreign currency and interest rate derivatives, and trade receivables. We do not believe that our cash equivalents or foreign currency and interest rate derivatives present significant credit risks because the counterparties to the instruments consist of major financial institutions that are financially sound, and we manage the notional amount of contracts entered into with any one counterparty. Substantially all trade receivable balances are unsecured. The concentration of credit risk with respect to trade receivables is limited by the large number of customers in our customer base and their dispersion across various industries and geographic areas. We perform ongoing credit evaluations of our customers and maintain an allowance for potential credit losses.
