Trying to answer this question but this is as far as I've gotten:

A Letter of Interest (LI) is a non-binding indication of EXIM’s general interest in a proposed transaction or project and provides indicative general financing terms that EXIM is prepared to consider based on a limited review of the transaction/project.

EXIM Preliminary Commitments (PCs) are non-binding preliminary offers of financing terms based on a credit evaluation and policy review, then approved by EXIM’s Board of Directors. PCs require more stringent due diligence standards than LIs, but less stringent standards for final commitments.
