Bloomberg News reports that Merrill Lynch & Co., Inc. (NYSE: MER) has extended its Auction Rate Securities (ARS) redemption offer in response to what I thought was pressure from New York Attorney General Andrew Cuomo who threatened to take Merrill to court. But what is interesting is that Massachusetts Secretary of State William Galvin was the one who announced the settlement.

While the politics of this intrigue me, those who held Merrill ARSs (pun intended) care about the terms of the settlement. Bloomberg reports that Merrill "will begin the buyback on October 15 for individuals, nonprofits and small business with $3 million or less on deposit. Redemptions for clients with $100 million or less start on January 15." This Merrill deal adds to the one it announced on August 7 -- a voluntary buyback of $10 billion worth of ARS. Merrill has a total of "30,000 clients who held an estimated $12 billion" according to Bloomberg.

This leaves many major ARS issuers lagging behind their peers. Here are four holdouts (with their 2007 municipal ARS issuance in parentheses):

• Goldman Sachs (NYSE: GS) ($4.3 B)
• Bank of America (NYSE: BAC) ($3.7 B)
• RBC Capital Markets ($1.2 B)
• Lehman Brothers (NYSE: LEH) ($1.1 B)

What are they waiting for?

Bloomberg News reports that banks' subprime write-downs have hit $500 billion. The last time I checked, that figure was $400 billion. Bloomberg reports that New York University economist Nouriel Roubini forecasts such losses will ultimately total $2 trillion. I wonder if he would revise his estimate upwards.

Recently banks have been taking write-downs for their Auction Rate Securities (ARS). Bloomberg reports about $1.9 billion has been set aside so far to cover ARS losses. It notes that UBS AG (NYSE: UBS) set aside $900 million to cover potential losses and Citigroup, Inc. (NYSE: C) and Wachovia (NYSE: WB) each estimate that their ARS buybacks will cost $500 million.

Write-downs have been going hand in hand with capital raising. But banks and brokers have not been able to raise enough capital to offset the losses. Bloomberg calculates that they've raised "$353 billion of capital to cope with the write-downs. The gap between the losses and capital infusions, which stands at $148 billion, has regularly narrowed to about $80 billion as capital raising follows write-down announcements."

Can banks and brokerages raise another $1.7 trillion to keep up with the write-downs that Roubini forecasts? I sincerely doubt it.

CNNMoney reports that Morgan Stanley (NYSE: MS) is the latest bank to buy back its worthless Auction Rate Securities (ARS) from individual investors. With that buyback, Morgan Stanley follows in the wake of Citigroup, Inc. (NYSE: C), Merrill Lynch & Co., Inc. (NYSE: MER) and UBS AG (NYSE: UBS).

CNNMoney notes that Morgan Stanley said it would offer to repurchase all ARS "held by individuals, charities and small and medium-sized business with accounts of $10 million or less at the bank." Morgan Stanley will begin to start buying back $4.5 billion worth of ARS on September 30th and will "make its best effort to provide liquidity solutions" for institutional investors by the end of 2009. But New York attorney general Andrew Cuomo is not satisfied with Morgan Stanley's proposal.

Meanwhile, the list of big ARS issuers that have not settled grows shorter. Here are six holdouts (with their 2007 municipal ARS issuance in parentheses):

• JPMorgan Chase (NYSE: JPM) ($5.2 B)
• Goldman Sachs (NYSE: GS) ($4.3 B)
• Bank of America (NYSE: BAC) ($3.7 B)
