Veteran general counsel Peter Lieb is leaving Aon after 10 years with the global brokerage.

According to a filing with the U.S. Securities and Exchange Commission, Lieb will transition from his role as executive vice president, GC and secretary at London-based Aon to a position as “special legal adviser” to the company's chief executive officer by year's end and retire, effective Dec. 31, 2020. In addition to his current base salary of $700,000, Lieb also will receive a cash payment of $1.8 million for duties carried out during the transition period.

Through a company spokesman, Lieb declined to comment on his move, but said in a statement: “After almost 25 years in the private sector, working primarily as an in-house corporate lawyer, I'm energized by the idea of using my legal skills to give back to our community in new and different ways. I have every confidence in our leadership team and the direction of the firm, making this an ideal time to transition my responsibilities.”
