Where would I find lending limit requirements for a bank affiliate such as discussed below?

I'm reviewing the following scenario:
Bank made a $10M loan to an affiliate/subsidiary of the bank. This company lends to businesses against their account receivables. The Bank is now considering an increase in their loan on an unsecured basis to the affiliate company.

Your help is appreciated.

208.73(d) references Federal Reserve Act 23A and 23B which was always reference material when dealing with affiliates. It might get you started. I believe there is more compliance content written by the agencies on 23A and B as well.

Thanks Andy
I'll review those.
