The Hartford is expanding its defined contribution platform with a trio of new managers and a slew of funds for retirement plan sponsors and participants.

Two new investment managers, Calamos Investments and Delaware Investments, have been added to retirement plans for both corporate and nonprofit sponsors. A third manager, TIAA-CREF, has been added for nonprofit sponsors, including schools, charities, government entities and others.

In addition, 16 new investment options, including the the PIMCO Total Return III Fund and the Invesco Real Estate Fund, are now available from the new and existing managers.

The Hartford’s open architecture platform now offers some 294 funds available through 80 fund managers.

“As more Americans approach or enter retirement, the focus on preparing for retirement and how best to achieve savings objectives continues to grow,” stated Sharon Ritchey, executive vice president of The Hartford’s Retirement Plans Group. “Plan sponsors and their participants want more choices to invest their hard-earned dollars as they plan for their later years.”
