The effect of foreign currency exchange in this table reflects the impact on goodwill of amounts recorded in currencies other than the U.S. dollar on the financial statements of subsidiaries in these geographic areas resulting from the yearly effect of foreign currency translation between the applicable functional currency and the U.S. dollar. The remaining goodwill for EMEA and the entire amount of goodwill for Asia Pacific represent amounts allocated in U.S. dollars from the U.S. to those geographic areas for financial reporting purposes.
