A Missouri Irrevocable Letter of Credit (ILC) is a type of credit guarantee issued by a bank or financial institution that is used to guarantee payment in the event of non-payment by the customer. It is an agreement between a bank and a customer that requires the customer to make payment to the bank, and the bank to make payment to a third party, if the customer fails to make the payment. The ILC is irrevocable, meaning it cannot be changed or canceled without the agreement of all parties involved. The Missouri Irrevocable Letter of Credit is commonly used in international trade and commerce to protect both the buyer and seller in a transaction. It is also used to guarantee payment of a loan, or to guarantee payment for a service or goods. There are two main types of Missouri Irrevocable Letter of Credit: Standby letters of credit and Confirmed letters of credit. A Standby Letter of Credit is a type of ILC that is issued to guarantee payment in the event of default by the customer. The bank promises to make the payment on behalf of the customer if the customer fails to make the payment. A Confirmed Letter of Credit is a type of ILC that is confirmed by a second bank in addition to the issuing bank. This type of ILC provides additional assurance that the payment will be made in the event of default by the customer.
