WASHINGTON - Only $109.6 billion remain in the government's $700 billion financial rescue fund.

But Treasury Department officials said this morning they expect the fund will be boosted over the next year by about $25 billion as some institutions pay back money they have received. That would boost the total to $134.6 billion.

The accounting details were made by Treasury Secretary Timothy Geithner in a letter to Elizabeth Warren, the head of the Congressional Oversight Panel.

In the letter, Geithner said the Bush administration had committed $355.4 billion in resources before it left office. That total included $117 billion committed to insurance giant American International Group Inc., banking giants Citigroup Inc. and Bank of America Corp., and auto companies General Motors Corp. and Chrysler LLC.

Since the Obama administration has taken office, an additional $30 billion has been committed to AIG and $5 billion to auto suppliers, bringing the total for what the administration termed "exceptional assistance" to $152.4 billion.

Another $218 billion has been committed to banks to bolster their capital reserves. So far, that program has disbursed nearly $200 billion to more than 500 banks nationwide with more applications pending. Former Treasury Secretary Henry Paulson had once set a goal of having $250 billion disbursed to banks.
