Letter of Credit

A letter of credit (LC), also known as a documentary credit or bankers commercial credit, or letter of undertaking (LoU), is a payment mechanism used in international trade to provide an economic guarantee from a creditworthy bank to an exporter of goods. Letters of credit are used extensively in the financing of international trade, when the reliability of contracting parties cannot be readily and easily determined. Its economic effect is to introduce a bank as an underwriter that assumes the counterparty risk of the buyer paying the seller for goods.
