U.S. attorney spokesman Bruce Riordan says 45-year-old David Tamman was convicted of 10 counts Tuesday after a two-week bench trial. He is scheduled to be sentenced in February.
Prosecutors say Tamman met with co-defendant John Farahi after the Securities and Exchange Commission made a surprise inspection of Farahi's investment fund business. Tamman then altered and backdated documents to make it seem like Farahi had told his customers about investment risks.
In June, Farahi pleaded guilty to conspiracy to obstruct justice and fraud charges. He is due for sentencing Dec. 17.
