Hogg, who joined the firm in 2007, was with Aegon for 20 years. During his time at Aegon, Hogg was most recently head of marketing for its India project and prior to that worked in the public affairs team on projects such as pension reform.
Under the AIG Life restructure, the role of chief operating officer has been scrapped and AIG Life Ireland general manager Elizabeth Larrissey will now report directly to chief executive Doug Brown.
AIG says that there will be no further redundancies as a result of the restructure and that the move to bring the Irish division closer to the UK was designed to introduce efficiencies in the business and has been planned for some time.
AIG did not want to comment further on the news but says Hogg has left the firm to pursue other opportunities.
