English to Spanish Bus/Financial Law (general)

How do you translate "Entrustment loans"? I have found this explanation...

"An entrustment loan is an indirect lending structure in which companies within a group
channel funds to one another with a bank acting as an agent to facilitate the loans.
Companies with excess cash (lenders) can place surplus funds as deposits with a bank
(entrust agent) to "lend" to designated companies (borrowers). The bank only acts as an
entrust agent and does not assume any credit risk. The structure requires a
predetermined amount, tenor and interest rates (negotiable using arm's length principles).
An entrustment loan is a common tool used by US companies to enhance their liquidity
management, through optimizing group cash balances and lowering onshore borrowing."

Thanks a lot!!
