Hartford Financial Services is seeking bids from two of its rivals for its property-casualty unit, a move seen as a possible breakup of the insurer.

New York-based Travelers and Zurich-based Ace Ltd. are among those showing possible interest, according to Bloomberg, as Hartford has begun soliciting offers for the unit, which has an estimated value of between $4 billion to $8 billion.

Bloomberg reports that the company has been pummeled by credit downgrades after losses in its life insurance division, but may not need to find buyers if assistance comes through the U.S. Treasury‘s Troubled Asset Relief Program.

Hartford is one of a few insurers who could benefit from billions of dollars though the program.

In February, Neal Wolin, president and chief operating officer of the Hartford’s property-casualty operations, left the company after eight years to accept a job at the White House as deputy counsel to the president for economic policy and deputy assistant to the president.
