In order to obtain a clear understanding of the working of a commercial letter of credit, we will take a concrete example and follow its every transaction. An importer of coffee (A) in New York purchases a certain number of bags of coffee from an exporter (B) in Brazil. A agrees to furnish B with a commercial letter of credit. B is not in position, we will say, to await the arrival of the coffee in New York and the return of a remittance before receiving his pay. A on the other hand is unable to remit B for the coffee before its receipt and sale to his customers. A goes to his banker in New York and requests him to authorize B to draw upon the New York banker's London correspondent at ninety days' sight with bills of lading for coffee to the amount of the purchase attached to the draft, consular invoice and insurance certificate, if B is to furnish insurance. If A's banker is willing to extend the credit he writes a letter (or uses a printed form), requesting his London banker to accept B's drafts upon presentation under the conditions already mentioned and others of minor importance. This letter is issued in duplicate, one copy going to the London banker, the other being delivered to A. A then mails the copy received by him to B. B thereupon arranges to ship the coffee, obtains the bill of lading, invoice, etc., and takes them with the copy of the credit to his banker in Brazil. A draft is then drawn on the London bank under the terms of the credit at ninety days' sight and is discounted by the Brazilian banker, the proceeds being placed to the credit of B's account or given to him in the form of a check or cash. The Brazilian banker then forwards the draft and documents, except such documents as the instructions may require to be forwarded direct to New York, to his London banker. He may secure discount of the bill at once by cable or await its arrival in London before doing so, or he may request his London banker to have the bill accepted and hold it for maturity. If the bill is discounted the Brazilian banker may draw against it immediately and thus put himself in funds to purchase other coffee bills. Upon receipt of the bill by the London correspondent it is presented to the London banker on whom it is drawn for acceptance. The acceptor bank examines the documents and if they are drawn according to the terms of the credit accepts the draft and returns it to the correspondent of the Brazilian bank, retaining the documents, which it then forwards to the New York bank which opened the credit. In accepting the draft the London bank has in effect agreed to pay it at the end of ninety days, or, figuring grace, ninety-three days. Upon maturity payment is made and the amount is charged to the account of the issuing New York bank. Upon receipt of the documents the New York bank delivers them to its customer under a trust receipt or against collateral, and the latter is then in position to obtain the goods. Ten
