The number of partners to leave Goldman Sachs since David Solomon took over as CEO just hit 90

• It’s been a busy summer for Goldman Sachs’ partner departures.
• Two more farewell memos went out on Tuesday, including for Lisa Opoku and David Rusoff.
• The bank said goodbye to Julian Salisbury and Takashi Murata on Friday. 

This is one summer David Solomon may want to forget. 

Just weeks after reporting a 58% drop in profit, the Goldman Sachs CEO was hit with a wave of high-profile defections that bring the number of partners who have left under Solomon to 90.
