In the latest signal that Wall Street's credit crisis has reached Main Street, the Minneapolis broker-dealer Ameriprise decided late Wednesday to pony up as much as $33 million to protect 330,000 client accounts in the event that the Reserve Primary Money Market Fund is liquidated at less than $1.00 per share.
The move means that Ameriprise clients with frozen assets in the troubled Primary Fund can rest easier.
The decision does not include clients of Ameriprise subsidiary Securities America.
"The unprecedented situation with the Reserve has caused significant anxiety and hardship for individual investors," said Ameriprise CEO Jim Cracchiolo in a statement.
"With this additional action, we are addressing losses incurred through an investment option that has for decades provided an unquestioned safe haven for consumers' cash," he said.
On Wednesday, TD Ameritrade also pledged up to $50 million to guarantee that its clients stuck in the Primary Fund get $1 back for every dollar they have invested. Both companies are taking this unprecedented action because the guarantees that the U.S. Treasury proposed last week for money market funds likely won't cover Primary Fund shareholders.
Last week, the New York-based Reserve Management Company's Primary Fund became only the second money market fund to ever "break the buck" -- industry lingo for money market shares that fall below $1.00 in value. Reserve and its investors were stung by the failure of mortgage-backed investments from now-bankrupt Lehman Brothers. Several other money market funds, including RiverSource's Cash Management Fund, would have broken the buck in recent weeks if their companies had not fronted the money to prevent it.
Wednesday's moves by Ameriprise and TD Ameritrade were no surprise to Peter Crane, founder of Massachusetts-based money market information company Crane Data LLC.
