The selected firm will serve for an initial one-year period beginning Jan. 1.
The plan represents the consulting firm’s first Mass.-based client.
The plan’s incumbents manage more than $1.2 billion.
The plan issued an RFP seeking a manager to handle $25 million after approving the search in April.
The three new commitments will total up to $130 million following approval from the full board later this month.
The search is being conducted in anticipation of the Dec. 31 contract expiration of incumbent Nationwide Retirement Solutions.
The search comes as the plan’s incumbent will see its contract expire this year.
The commitment represents a new relationship for the plan.
The plan replaced both its passive equity and fixed-income mandates with Vanguard Group after receiving an annual share class review in February.
Plan also expects to receive an international value equity manager search update form its consultant later this month.
