Every quarter, Bronx Co. ships computer chips to a firm in central Asia. It has not used any trade financing because the importing firm always pays its bill in a timely manner upon receipt of the computer chips. After the September 11, 2001, terrorist attack on the United States, Bronx reconsidered whether it should use some form of trade financing that would ensure that it would be paid for its exports upon delivery. Offer a suggestion to Bronx Co. on how it could achieve its goal.
