Mortgage lender


( IMB) continued its free fall Tuesday, even as

Federal Reserve

Chairman Ben Bernanke attempted to soothe the financial markets.

The California-based lender collapsed more than 30% to 44 cents after saying it doesn't have enough capital to remain regarded as "well-capitalized" by regulators. IndyMac can't fund its lending with deposits acquired through independent brokers, and its request for a waiver from the Federal Deposit Insurance Corp. to allow for brokered deposits hasn't been approved, the company said. IndyMac also said it will lay off half of its workforce.

The company pinned blame on recent negative comments from Sen. Charles Schumer (D., N.Y.), which caused a run on the bank as depositors began pulling their money. Shares recently were losing 38% to 44 cents.

A strict reading of that rule force Fannie Mae and Freddie Mac to raise a combined $75 billion in additional capital, according to Lehman Brothers.
