Geoffrey Berman, the court-appointed U.S. attorney for the Southern District of New York, reported earning about $3.5 million in salary and bonus last year at Greenberg Traurig, where his clients included Deutsche Bank and a handful of individuals, according to a financial disclosure released on Thursday.

Berman’s disclosure, a required filing for many top government officials, provides a peek into the compensation scheme at one of the country’s largest law firms and a broad picture of the client relationships the former white-collar defender left behind when he took over one of the most visible U.S. attorney offices in the country.
