13 Pa.C.S. § 5118: Security interest of issuer or nominated person.

(a) General rule.--An issuer or nominated person has a security interest in a document presented under a letter of credit to the extent that the issuer or nominated person honors or gives value for the presentation.

(b) Duration.--So long as and to the extent that an issuer or nominated person has not been reimbursed or has not otherwise recovered the value given with respect to a security interest in a document under subsection (a), the security interest continues and is subject to Division 9 (relating to secured transactions), but:

(1) a security agreement is not necessary to make the security interest enforceable under section 9203(b)(3) (relating to attachment and enforceability of security interest; proceeds; supporting obligations; formal requisites);

(2) if the document is presented in a medium other than a written or other tangible medium, the security interest is perfected; and

(3) if the document is presented in a written or other tangible medium and is not a certificated security, chattel paper, a document of title, an instrument or a letter of credit, the security interest is perfected and has priority over a conflicting security interest in the document so long as the debtor does not have possession of the document.
