Bailey accused the broker, Karl Hahn, who worked at the three firms consecutively for roughly seven years between 2004 and 2011, of misrepresenting covered calls, a variable annuity and other investments he recommended while at the three firms.

Those other investments included unsuitable premium-financed life insurance on which Mr. Hahn generated large commissions, Michael Perry, the attorney who represented Bailey told Dow Jones Newswires.

Hahn also convinced Bailey to invest roughly US$2.3 million in a real-estate financing deal involving properties on the coast of New Hampshire that ultimately "turned out to be completely fraudulent," said Perry, a shareholder at Murphy & King in Boston. "He just took the money."

The investor lost about US$6 million in total from his investments with Hahn, the attorney added.
