(CNNMoney.com) -- The Securities and Exchange Commission has filed fraud charges against the operators of the Reserve Primary Fund for failing to provide important information to investors and trustees about the fund's exposure to Lehman Brothers.
By bringing the case, the agency is trying to get the company to release the $3.5 billion it is withholding from shareholders until all lawsuits against the company are resolved.
The money market fund "broke the buck" on Sept. 16, the day after Lehman Brothers filed for bankruptcy, meaning its net asset value fell below $1 a share. Investors seek out money market funds as conservative investments because they are designed to maintain their $1 per share value. Companies also rely on them to purchase short-term corporate debt.
The Primary Fund, however, held $785 million in Lehman-issued securities, which lost most of their worth in the bankruptcy, the SEC said. This dragged down the fund's net asset value.
The agency says that the Reserve Management Company Inc., its chairman Bruce Bent Sr., vice chairman and president Bruce Bent II and Resrv Partners Inc. misled investors and "significantly understated" the volume of redemption requests. They also failed to provide trustees with accurate information about the value of the Lehman securities.
Reserve also said it would provide the money needed to maintain the fund's share value when it "had no such intention," according to regulators.
"Fund managers have serious obligations to keep their trustees and investors informed in both good times and bad, and cannot choose to reveal only favorable facts," said James Clarkson, acting director of the SEC's New York regional office.
The company said in a statement that it intends to defend itself vigorously.
"Since we created the money fund in 1970 we have operated and grown our business by putting our shareholders' interests first," said Bruce Bent Sr. "The Lehman Brothers Bankruptcy filing created an unforeseeable and out-of-control condition for many parties and the results were serious...We remain confident that we acted in the best interest of our shareholders."
There are at least 29 different lawsuits pending against the company, according to the SEC. The agency hopes to bring all claimants together in this case and have it settled together.
The Primary Fund is currently being liquidated. Last month, the company said about $46.1 billion, or approximately 90% of fund assets as of Sept. 15, 2008, has been returned to investors. Approximately $4.5 billion remains in the fund, which once had a value of $60 billion.
The fund's independent trustees, who oversee its operations, said in a statement that they would work with the agency.
"The trustees will continue to fully cooperate with the Securities and Exchange Commission to expedite the distribution of the remaining assets to shareholders and to ensure that all decisions are made in the shareholders' best interest," the trustees said.
