Cash and carry was a policy requested by U.S. President Franklin Delano Roosevelt at a special session of the United States Congress on September 21, 1939. It replaced the Neutrality Acts of 1939. The revision allowed the sale of material to belligerents, as long as the recipients arranged for the transport using their own ships and paid immediately in cash, assuming all risk in transportation.
