What the ERISA Fidelity Bond (Wisconsin) is for
Federal law (ERISA) requires most employee benefit plans to bond the people who handle plan money, and service businesses use fidelity bonds to protect clients from employee theft.
The bond amount is set by the agency, utility or fund that asks for it. If the bond holder doesn't meet their obligations, a valid claim is paid up to that amount, and the bond holder repays the surety.
