IndyMac Bancorp Inc. said in bankruptcy filings that its debts are more than 21 times its assets of $20.4 million.

IndyMac is the holding company whose main asset, IndyMac Bank, was taken over by the Federal Deposit Insurance Corp. in July after a run by depositors left it strapped for cash. As a result, the Pasadena holding company was left with little of value and it filed for bankruptcy protection Aug. 1. It said in Los Angeles bankruptcy court this week that its debts and liabilities total nearly $443 million.

The list of unsecured creditors includes trusts affiliated with the bank, which had combined estimated claims of $218 million, according to court papers obtained by Bloomberg News. IndyMac said it has made several transfers to subsidiary IndyMac Bank FSB that it can’t detail because it doesn’t have access to records now in the possession of regulators.

Creditors holding secured claims include Lehman ABS Corp., Morgan Stanley Mortgage Capital Inc. and the Los Angeles County Treasurer and Tax Collector. The value of their claims are listed as unknown.

IndyMac also disclosed past compensation for Michael Perry, the company’s chairman, chief executive and now sole remaining employee. Perry received a deferred compensation payment of $1.5 million June 15, following a Jan. 15 payment of $944,980. Perry’s 2007 base salary was $1 million, plus $105,270 in other pay, the S & L; holding company said.

In other news, the Los Angeles Times reported Tuesday that IndyMac’s uninsured deposits at the time it was taken over totaled only about $600 million, down from the more than $1 billion first estimated, according to a memo written by John Bovenzi, the FCIC official now running IndyMac.

An FDIC spokesman said the new estimate of uninsured deposits stemmed from efforts to identify ways that customers had structured their deposits to stay within FDIC insurance limits, such as jointly held or trust accounts.
