In a statement by Moody's, the move comes after Hartford announced on Monday that it booked $2.2 billion in investment losses for the third quarter and took a $915 million write-down on deferred acquisition costs.
The agency affirmed the "Aa3" financial strength rating on the company's main property and casualty and life insurance units. The outlook for the life unit remains negative, while the outlook for the P&C unit is stable.
Hartford, responding to the Moody's statement, said it remains financially strong after taking action earlier this week to bolster its financial position. The company received a $2.5 billion capital injection from Germany's Allianz, in a move that came after Hartford's shares lost half their value last week, while the cost to insure its debt swelled to record levels on fears about its exposure to credit markets.
A.M. Best Co. also placed the financial strength ratings of Hartford under review with negative implications.
