International ratings agency Moody's has upgraded its long term debt ratings on American General Corporation to Aaa from Aa2.
The agency said the upgrade related to a guarantee from American General's parent, American International Group (AIG), a US-based insurance and financial services company.
Moody's said the guarantee applied to existing debt and debt to be issued under American General's outstanding shelf registration.
AIG completed its acquisition of American General in late August this year.
