Tax Reporting: When a foreign security is sold, how does IBKR apply a currency exchange rate?

If the proceeds of a sale are paid in foreign currency, IBKR must convert the amount to be reported into US dollars. Generally, IBKR converts the foreign currency on the payment date at the spot rate or by following a reasonable spot rate convention, for example a month-end spot rate or monthly average spot rate. Your Activity Statements reflect the spot rate at the end of the applicable month or year depending upon the statement you are viewing. Interest or dividend payments are converted at the spot rate on day of payment for purposes of Form 1099 reporting.
