Research in Motion (RIMM) said the U.S. attorney is looking into its stock option accounting problems.
The Waterloo, Ontario, maker of the BlackBerry wireless email device said it needs more time to finish planned restatements of past financial results. The company, which is already under investigation by the
Securities and Exchange Commission
and the Ontario Securities Commission, said it "has had contact with the office of the U.S. Attorney for the Southern District of New York upon learning that the U.S. Attorney's office is reviewing the company's stock option grants."
RIM said last month that restating earnings to fix accounting errors tied to questionable stock option grants will wipe $250 million off past profits. RIM had previously predicted that the option probe would result in a charge of $25 million to $45 million.
RIM said it plans to cooperate with various investigations.
