Citigroup sold off the last of its 8 million share stake in Primerica. Primerica was spun off in an initial public offering in April 2010. After that deal, Citigroup owned about 40 percent of Primerica common stock. In April 2011, Citigroup publicly sold 12 million shares of Primerica stock, reducing its ownership stake to 23.1 percent.

Primerica repurchased $200 million in shares in November, reducing Citigroup's ownership to 12.5 percent. The sale this week completes the process of Citigroup selling off its remaining equity stake in Primerica.

"This announcement marks the culmination of our "Refounding," said John Addison, chairman of Primerica Distribution and co-CEO. "It is an exciting and historic day for our company and we wish to thank our 2,000 employees in North America, as well as our more than 90,000 independent representatives, without whom this day would not be possible. We are a Main Street company with a singular mission to grow our business and continue to deliver for Main Street families in North America by helping them achieve greater financial independence."
