Last year, $100 million in outstanding bank loans to a developing nation's government were not renewed, and the developing nation's government paid off $50 million in maturing government bonds that had been held by foreign residents. During that year, however, a new group of banks participated in a $125 million loan to help finance a major government construction project in the capital city. Domestic firms also issued $50 million in bonds and $75 million in stocks to foreign investors. All of the stocks issued gave the foreign investors more than 10 percent shares of the domestic firms.
