Liquidation trustees for the defunct Rothstein Rosenfeldt Adler law firm and Banyon Income Fund have reached a $4.7 million settlement with insurance broker Aon Risk Services in a negligence suit.

The Jan. 2 settlement was the latest development in a decadelong saga involving former litigator Scott Rothstein’s  $1.2 billion Ponzi scheme, and Gibraltar, the Coral Gables private bank used by Rothstein to launder money. The trustees of Rothstein’s shuttered law firm and Banyon, a South Florida hedge fund used by Rothstein as a feeder to pump money into his scheme, filed a complaint against Aon in September 2017.
