Summary of Significant Accounting Policies and Practices [Abstract]

Foreign Currency Transactions and Translations Policy [Policy Text Block]

Foreign currencies

Assets and liabilities denominated in currencies other than the functional currency of a subsidiary are remeasured at rates of exchange on the balance sheet date. Resulting gains and losses on foreign currency transactions are included in the Consolidated Statements of Operations.

The financial statements of foreign subsidiaries where the functional currency is not the U.S. dollar are translated to U.S. dollars using (i) exchange rates in effect at period end for assets and liabilities, and (ii) weighted average exchange rates during the period for revenues and expenses. Adjustments resulting from translation of such financial statements are reflected in accumulated other comprehensive income (loss) as a separate component of consolidated equity.
