S&P Global Ratings has changed the outlook on AIG General Insurance's A+ financial strength and issuer credit ratings to positive from stable while also affirming the ratings, according to a Tuesday release.

The positive outlook, which is the same as that of other core subsidiaries of the AIG group, considers S&P's view that AIG General Insurance will continue to be a core operating unit for the group.

S&P also considers the Japan-based insurer as capable of enduring its Japan sovereign default stress test on its own due to healthy capital levels and sufficient liquidity.

Changes in AIG's group credit profile assessment and outlooks on other core subsidiaries could trigger future rating actions, S&P said.
