Before the audit by CalPERS, Rizzo was in line to collect $600,000 to $1 million per year.
Now though, he's expected to get less than $100,000 a year.
Rizzo is one of eight former and current city leaders charged with misappropriating more than $5.5 million from the city treasury.
The Justice Department is investigating potential civil rights and voting rights violations by the city, and the state controller, the U.S.
The Securities and Exchange Commission and the State Department of Corporations also are investigating Bell's finances.
