Credit Suisse Group AG, the second-biggest Swiss bank, said it's in advanced discussions on the restructuring of a derivatives transaction the firm used to award more than 5,500 employees part of their 2011 bonuses. The need to revamp the so-called Partner Asset Facility 2 arose because the Basel Committee on Banking Supervision said last year in a paper on counterparty credit risks under the new Basel III rules that a hedge of such exposure isn't valid if a bank is providing a liquidity facility or another kind of credit enhancement to the provider of the hedge.
