Building Funding and Liquidity Management Framework in an investment bank

Dear monkeys,

Understand lots of you are working at the front office, but would appreciate if someone could cast some light on the current practices at leading investment banks with regard to how they operate internally on assigning funding costs to various lines/products in a way that is fair and agreed by all?

After the crisis understand lots of firms are revamping the framework to better price risk and liquidity internally. Asian broker dealers are currently trying to catch up with the leading industry practices especially when it comes to back office functions, risk, treasury, finance etc.

Your expertise and advise will be highly appreciated.
