revolving letter of credit (L/C)

Definition

Single L/C that covers multiple-shipments over a long period. Instead of arranging a new L/C for each separate shipment, the buyer establishes a L/C that revolves either in value (a fixed amount is available which is replenished when exhausted) or in time (an amount is available in fixed installments over a period such as week, month, or year). L/Cs revolving in time are of two types: in the cumulative type, the sum unutilized in a period is carried over to be utilized in the next period; whereas in the non-cumulative type, it is not carried over.
