In its latest monthly operating report with the Securities and Exchange Commission, Lehman Brothers this week listed a fresh $53.1 million in fees and expenses paid to outside advisers for their bankruptcy-related work during May. Lead bankruptcy counsel Weil, Gotshal & Manges, which received nearly $16 million for its efforts in the Chapter 11 case, led the pack among professional services firms.

The May billings bring Weil’s total earnings in the case, which will be three years old in September, to $309.8 million.
