Kansas Public Employees Retirement System, Topeka, is adding the Vanguard Mid-Cap Growth Fund to the lineup of its $943 million 457 plan, said spokeswoman Kristen Basso in an e-mail.
The Vanguard Group fund will replace the Columbia Acorn A Fund, a midcap growth fund, which is being removed for performance, Ms. Basso wrote.
About $15 million is currently invested in the fund, which is managed by Columbia Management Investment Advisers. Participants could be mapped to the replacement fund in May.
A Columbia spokesman declined to comment on the fund’s removal.
