21.   Transaction Exposure. Vegas Corp. is a U.S. firm that exports most of its products to Canada. It his- torically invoiced its products in Canadian dollars to accommodate the importers. However, it was adversely affected when the Canadian dollar weak- ened against the U.S. dollar. Since Vegas did not hedge, its Canadian dollar receivables were con- verted into a relatively small amount of U.S. dol- lars. After a few more years of continual concern about possible exchange rate movements, Vegas called its customers and requested that they pay for future orders with U.S. dollars instead of Canadian dollars. At this time, the Canadian dollar was val- ued at $.81. The customers decided to oblige since the number of Canadian dollars to be converted into U.S. dollars when importing the goods from Vegas was still slightly smaller than the number of Canadian dollars that would be needed to buy the product from a Canadian manufacturer. Based on this situation, has transaction exposure changed for Vegas Corp.? Has economic exposure changed? Explain.
