Coca-Cola Bottling Co. of Northern New England Inc., Bedford, N.H., hired American Express Retirement Services as the bundled provider for its $45 million 401(k) plan. Coca-Cola Bottling had been with Fleet Street Bank since the plan was formed 14 years ago, said Ann Marie Lacharite, director of human resources. The company also expanded the investment options to eight from six and widened the choices, said Ms. Lacharite. All of the investment options are offered through American Express or an alliance partner. The two new types of investment options are the American Express Trust Income Fund and an American Express small-cap equity fund. The other options are the AXP Selective fund; AIM Balanced; American Century Income and Growth; AXP New Dimensions; Baron Asset; and Janus Overseas. In a few years, plan executives intend to investigate adding a brokerage window option, Ms. Lacharite said.
