For the newly merged Squire Patton Boggs, 2015 has already brought significant partnership departures. Stuart Pape, who’d served as managing partner of the old Patton Boggs firm for 14 years, until 2011, left on Feb. 4. Also planning departures are star white-collar litigator Robert Luskin and his team, which could mean a revenue loss of $20 million or more for the firm.

In a development that might have hastened some departures, Squire Patton Boggs has distributed almost zero profits from 2014 to its legacy Patton Boggs partnership this year, partners said. Multiple equity partners received 45 percent less in compensation than they had expected for the year. A firm spokesman says that the after-tax compensation for legacy Patton Boggs partners was “at or very near the estimate at the time of the merger.”
