Last year Pimco also started advising the National Association of Insurance Commissioners to  reassess the level of mortgage risks that insurance firms have to improve the system for rating bonds.

Aside from chief executive, Weil also becomes a member of the Janus Capital board on Feb. 1.
He succeeds Janus Capital's director Tim Armour who was interim CEO since July 2009. Armour took over the executive role after CEO Gary Black resigned in July in what the company called a "mutual decision."

Weil, 46, was at PIMCO for 13 years. He spent nine years as the company's chief operating officer. Before joining PIMCO in 1996, he was at Bankers Trust Global Asset Management and Simpson Thacher & Bartlett, which is a New York law firm.
