Current AIG boss Ed Liddy says he is stepping down. Who will take over as CEO of the troubled company? Study our form guide, compiled by David Sandham and David Banks, and place your bets.

4-1 Joint Favourite Jim Schiro

Current job CEO, Zurich Financial Services (ZFS).

Tipped by Industry veteran and ex-AIG man Tom Kaiser; also tipped by Bill Cooper, one of AIG’s bankers.

Form: An accountant who rose to CEO of PricewaterhouseCoopers. Then became the first

foreigner to be boss of ZFS, despite not speaking German and never having worked in the insurance

industry before.

He pulled ZFS out of banking and cut jobs. Aged 63, he retires from ZFS by the end of this year, so is looking for a job.

GR TIP Our joint favourite.

4-1 Joint Favourite Brian Duperreault

Current job President and CEO, Marsh & McLennan Companies

Tipped by Former senior AIG courtier Ron Shelp (Ron’s second choice); also tipped by Bill Cooper, one of AIG’s bankers.

Form: Knows AIG like the back of his hand, as he worked there for 20 years. On top of which he was CEO of Ace Ltd for 10 years. Widely liked, but has only been in his current job since January last year, so may want to do more there. Asked who he thought should be the next CEO of AIG, he replied: “No comment. Whoever it is, they’ll have a tough job.” GR TIP Our joint favourite.

7-1 On the Inside Track, Kris Moor

Current job President of AIU, the property and casualty division of AIG.

Tipped by Jeff Carr, currently at ACE, previously at AIG. Praised by Bob Willumstad former CEO of AIG.

Form: Moor currently runs the core part of AIG.

Rumoured to subject his managers to tough grillings on their figures. His identification with AIU as a brand that is becoming increasingly independent of AIG could rule him out of the race.

GR TIP Good manager, but he is likely to stick with AIU.

25-1 Plucky Outsider Hank Greenberg

Current job Chairman and CEO of C V Starr.

Tipped by Ron Shelp and by Jake DeSantis, former AIG Financial Products guru whose resignation letter to

Ed Liddy was splashed in The New York Times earlier this year.

Form: Once boss of AIG, Greenberg fell victim to then New York Attorney General Eliot Spitzer’s inquiry into the insurance industry.

Currently in a legal battle with AIG – perhaps not the best recommendation for becoming its boss.

But many who have worked with him describe him as a brilliant manager with an eye for detail. He would never have allowed AIG to get into its current mess, they say.

GR TIP A brilliant man, an original, but too much history.

500-1 Rank Outsider Martin Sullivan

Current job Unknown.

Tipped by Mentioned (not tipped) by ex-AIG man Phil Somers.

Form: Essex boy who clawed his way to the CEO position at AIG (he got the job after Greenberg left), only to be blamed for leading the company into disaster.

GR TIP No hope.

1000-1 The Owner Barack Obama

Current job CEO of the United States.

Tipped by Rob Basford, senior underwriter at M4 Underwriting, previously a development underwriter at AIG (who may have been joking!).

Form: Err, should he really be here? But then again, he liked the company so much that he bought it!

GR TIP You could argue he already is the CEO, in effect. AIG is currently 80% owned by the US government.

Who else?

Ex-AIG manager Anthony Mammolite speculates the new CEO might come from one of the six who joined the board at the end of June: Harvey Golub, Laurette Koellner, Christopher Lynch, Arthur Martinez, Steve Miller and Douglas Steenland.
