(a) A letter of credit is issued and becomes enforceable according to its terms against the issuer when the issuer sends or otherwise transmits it to the person requested to advise or to the beneficiary. A letter of credit is revocable only if it so provides.

(b) After a letter of credit is issued, rights and obligations of a beneficiary, applicant, confirmer, and issuer are not affected by an amendment or cancellation to which that person has not consented except to the extent the letter of credit provides that it is revocable or that the issuer may amend or cancel the letter of credit without that consent.

(c) If there is no stated expiration date or other provision that determines its duration, a letter of credit expires one year after its stated date of issuance or, if none is stated, after the date on which it is issued.

(d) A letter of credit that states that it is perpetual expires 5 years after its stated date of issuance, or if none is stated, after the date on which it is issued.

This section is referenced in § 28:5-103.

1. This section adopts the position taken by several courts, namely that letters of credit that are silent as to revocability are irrevocable. See, e.g., Weyerhaeuser Co. v. First Nat. Bank, 27 UCC Rep.Serv. 777 (S.D. Iowa 1979); West Va. Hous. Dev. Fund v. Sroka, 415 F.Supp. 1107 (W.D.Pa.1976). This is the position of the current UCP (500). Given the usual commercial understanding and purpose of letters of credit, revocable letters of credit offer unhappy possibilities for misleading the parties who deal with them.

2. A person can consent to an amendment by implication. For example, a beneficiary that tenders documents for honor that conform to an amended letter of credit but not to the original letter of credit has probably consented to the amendment. By the same token an applicant that has procured the issuance of a transferable letter of credit has consented to its transfer and to performance under the letter of credit by a person to whom the beneficiary’s rights are duly transferred. If some, but not all of the persons involved in a letter of credit transaction consent to performance that does not strictly conform to the original letter of credit, those persons assume the risk that other nonconsenting persons may insist on strict compliance with the original letter of credit. Under subsection (b) those not consenting are not bound. For example, an issuer might agree to amend its letter of credit or honor documents presented after the expiration date in the belief that the applicant has consented or will consent to the amendment or will waive presentation after the original expiration date. If that belief is mistaken, the issuer is bound to the beneficiary by the terms of the letter of credit as amended or waived, even though it may be unable to recover from the applicant.

In general, the rights of a recognized transferee beneficiary cannot be altered without the transferee’s consent, but the same is not true of the rights of assignees of proceeds from the beneficiary. When the beneficiary makes a complete transfer of its interest that is effective under the terms for transfer established by the issuer, adviser, or other party controlling transfers, the beneficiary no longer has an interest in the letter of credit, and the transferee steps into the shoes of the beneficiary as the one with rights under the letter of credit. Section 5-102(a)(3). When there is a partial transfer, both the original beneficiary and the transferee beneficiary have an interest in performance of the letter of credit and each expects that its rights will not be altered by amendment unless it consents.

The assignee of proceeds under a letter of credit from the beneficiary enjoys no such expectation. Notwithstanding an assignee’s notice to the issuer of the assignment of proceeds, the assignee is not a person protected by subsection (b). An assignee of proceeds should understand that its rights can be changed or completely extinguished by amendment or cancellation of the letter of credit. An assignee’s claim is precarious, for it depends entirely upon the continued existence of the letter of credit and upon the beneficiary’s preparation and presentation of documents that would entitle the beneficiary to honor under Section 5-108.

3. The issuer’s right to cancel a revocable letter of credit does not free it from a duty to reimburse a nominated person who has honored, accepted, or undertaken a deferred obligation prior to receiving notice of the amendment or cancellation. Compare UCP Article 8.

4. Although all letters of credit should specify the date on which the issuer’s engagement expires, the failure to specify an expiration date does not invalidate the letter of credit, or diminish or relieve the obligation of any party with respect to the letter of credit. A letter of credit that may be revoked or terminated at the discretion of the issuer by notice to the beneficiary is not “perpetual.”
