The chairman and chief executive of American International Group (AIG) has dismissed concerns about a possible credit downgrade for the company which is the world's largest insurer by market value.
Investors have speculated about a downgrade for the company since the world's largest reinsurer Munich Re had its credit downgraded by ratings agency Standard & Poors last week.
Maurice Greenberg who is chairman and chief executive of the company said he was confident that the insurer's AAA rating would remain.
The review is being carried out by Moody's Investors services.
