Exchange Rates
The accounts of foreign subsidiaries with non-USD functional currencies (such as MPC Capital) are translated, and the resulting cumulative translation adjustments are recorded in Other Comprehensive Income (OCI) in the consolidated statements of comprehensive income and accumulated in Accumulated Other Comprehensive Income (AOCI) within equity. More specifically, assets and liabilities are translated into the reporting currency at the closing rate. Income and expense items are translated at the average exchange rate for the period. The following EUR/USD exchange rates have been used for the reporting period.
