anglais vers français Affaires / Finance Finance (général) Loan

At this we leave to the discretion of the Pledge and Security Department settlement of issues relating to the acceptability and correspondence of pledged assets with the amount of requested credit and terms of crediting.

The sentence refers to a declaration made by one of the parties to some legal proceedings. It refers to the granting of loans against pledges, warranties, and such. I am at a loss regarding the proper wording for a bank department that handles "pledge and security".

Any insight is more than welcome.

Thanks in advance.
