Albany, N.Y. ? The nation’s largest insurance brokerage will pay $850 million in restitution to end New York Atty. Gen. Eliot Spitzer’s investigation into bid rigging and price fixing in a settlement the company hopes will end other states’ investigations and private lawsuits.

Marsh & McLennan Companies Inc. will provide restitution over four years to clients, most of which were corporations. The payout will include $130 million to customers in California, $94 million to New York clients, $58 million in Pennsylvania and $55 million to Texas clients. Companies that accepted the payment would agree not to sue Marsh.

“It is one of the largest restitution funds in history that we are aware of from a single company,” Spitzer said.

Marsh & McLennan also issued an apology calling its conduct “unlawful” and “shameful,” Spitzer said.
