Ex-CEO Denis Field's trial for his alleged lead-wolf role in the tax shelter case started last week, while the rest of his fellow wolves - Michael Kerekes, Adrian Dicker, Charles Bee Jr. and Robert Greisman - all pleaded guilty back in 2009.
Led by Field, BDO Seidman was one of the most aggressive tax-shelter marketers, starting in the late 1990s. Inside the firm, the tax-shelter team was known as the "wolf pack." Field became CEO of the firm in 2000. Tax services accounted for nearly half of BDO Seidman's $420 million in U.S. revenues in 2002, up from 28 percent in 1998.
