2 questions for those that actually do banking

Can someone who has done this in practice help me out with these 2 things.

A) what's the best way to calculate NWC? I know it's suppose to be CA-CL-Cash. But what about stuff like income tax receivable, deferred tax assets, short-term borrowings, income-tax payables, etc? I need a clear of knowing what to include and what to exclude.

B) for people who have built lbo models before, how do you get the forward LIBOR rate off bloomberg/any other source? Please tell me the exact functions.

Thanks mates.
