Credit risk Leveraged Finance Group Buldge Bracket

Does anyone have info about the leveraged finance group within credit risk at a BB firm(GS/UBS/JPM). Is it deal based and does the c/r group work with the IBD group on deals , i.e the c/r lev finance team would focus on structuring debt and rating advisory? Or is it different like, if the firm lends money to a lev finance client (PE/corporations) the c/r lev finance team would work on that?

If not, can someone give an example of what the lev finance ibd team would do for a deal and what the c/r team would do? Or if they arent related a type of deal a c/r lev finance group would do.

Thanks
