U.S. direct investment abroad is defined as ownership by a U.S. investor of at least 10 percent of a foreign business. The direct investor is known as a U.S. parent, and the U.S.-owned foreign business is known as a foreign affiliate. International transactions statistics cover the foreign affiliates’ transactions with their U.S. parents, so these statistics focus on the U.S. parent’s share, or interest, in its affiliates rather than on the affiliates’ overall size or level of operations. The major items include capital flows, which measure the funds that U.S. parents provide to their foreign affiliates, and income, which measures the return on those funds. Direct investment position statistics are stocks and are cumulative; they measure the total outstanding level of U.S. direct investment abroad at year end.
