The network of money transfers of Western Union is the world's largest. In the 30's of the twentieth century, Western Union has become the world's largest telegraph company. The size of the commission fee for the transfer is charged according to the Western Union tariffs and depends on the amount of money sent. In the summer of 1990 top managers of the Western Union Company spent day and night in the main office in Englewood (Colorado, USA). They needed to meet the challenge: to save the Western Union from bankruptcy, paying off the debts of the company millions of dollars.
