Currency Translation And Transaction Adjustments [Abstract]
Currency Translation And Transaction Adjustments	15. CURRENCY TRANSLATION AND TRANSACTION ADJUSTMENTS All assets and liabilities of foreign operations in which the functional currency is not the U.S. dollar are translated into U.S. dollars at prevailing rates of exchange in effect at the balance sheet date. Revenues and expenses are translated using average rates of exchange for the year. Adjustments resulting from the process of translating the financial statements of foreign subsidiaries into U.S. dollars are reported as a separate component of equity, net of tax, where appropriate. Realized foreign currency transaction amounts included in the consolidated statements of operations include losses of $48, $64 and $89 in 2019, 2018 and 2017, respectively.
