A Brattle principal was retained as an expert in the bankruptcy of GSC, a credit-oriented investment management firm, on behalf of Black Diamond Capital Management Group. The case issues were related to market fee rates for a variety of structured credit and private equity investment products, 363 asset sales, valuation of management contracts, and whether new investments made by Black Diamond were made on arms-length terms and at market prices. Our principal issued an expert report, provided deposition testimony, and testified at trial in Bankruptcy Court for the Southern District of New York.
