Principal Financial Group Inc. may seek “strategic” investors as a way to raise capital as market conditions continue to deteriorate, the company said in a regulatory filing today, Bloomberg reported.

The company could also issue securities and cut expenses to ensure that its cash flow is sufficient for current liquidity needs, according to the filing. Bloomberg noted that the phrase “strategic investor” often signifies that a company may be interested in receiving bids for all or part of its business.

“Market conditions may limit our ability to replace, in a timely manner, maturing liabilities; satisfy statutory capital requirements; fund redemption requests on insurance and other financial products,” Principal said in the filing.

Principal has already halved its dividend, suspended share repurchases and cut jobs to secure cash as losses and write-downs related to the subprime mortgage market totaled about $4.5 billion last year, according to Bloomberg data.

Principal has sought as much as $2 billion from the Treasury Department’s Troubled Asset Relief Program. Iowa Insurance Commissioner Susan Voss also has loosened reserve requirements on the insurer, increasing the statutory surplus at Principal’s main life unit by about $387.4 million.
