Rhode Island Higher Education Assistance Association, Providence, formed a committee to investigate the administrator of the states $4 million higher education savings plan. The administrator, Collegiate Capital, also administered the higher education savings plan in Connecticut until it was fired from that role by Connecticut state Treasurer Denise Nappier in September. Collegiate President Christopher Stack is a cooperating witness in a federal investigation that already has resulted in former Connecticut state Treasurer Paul Silvester pleading guilty to bribery, racketeering and money laundering. Although it has not been accused of any wrongdoing, Collegiate Capital was fired by Ms. Nappier because of concerns about the firms ability to handle the administration of the program and manage its growth. A Rhode Island Treasury spokeswoman said the recent developments in Connecticut led to the decision to investigate Collegiate. A spokeswoman for the Rhode Island association said she expects the committee to make a recommendation to the board in the next few weeks. Mr. Stack admitted to participating in a scheme in which he kicked back to Mr. Silvester sales commissions he earned as a third-party marketer for some private equity firms that received investment allocations from the $18 billion State of Connecticut Trust Funds. Mr. Stacks attorney has said his client approached the U.S. Attorney about the illegal payments and is not being prosecuted.
