Yearly average exchange rate.
(2) Yearly average exchange rate. For purposes of section 987, the yearly average exchange rate is a rate that represents an average exchange rate for the taxable year (or, if the section 987 QBU existed for less than the full taxable year, the portion of the year during which the section 987 QBU existed) computed under any reasonable method. For example, an owner may determine the yearly average exchange rate based on a daily, monthly, or quarterly averaging convention, whether weighted or unweighted, and may take into account forward rates for a period not to exceed three months. Use of an averaging convention that is consistent with the convention used for financial accounting purposes is generally presumed to be a reasonable method. However, the Commissioner may prescribe an appropriate yearly average exchange rate if the Commissioner determines that the use of the convention would not have been expected to clearly reflect income based on the facts and circumstances available at the time of the election.
