Sandia Corp., Albuquerque, N.M., added small-cap funds from Dimensional Fund Advisors and Frank Russell as investment options in its $1.3 billion 401(k) plan and a $294 million 401(a) plan, said David C. Medina, savings plan administrator. The plans will drop an emerging growth fund managed by Credit Suisse because "it has not kept up with its peer group,” Mr. Medina said. The plans share the same 18 investment options, he said.
