Shareholders for NFP, a provider of benefits, insurance and wealth management services, will receive $25.35 in cash for each share of NFP common stock they own.

The deal has been unanimously approved by the full board of directors of NFP. Douglas W. Hammond, president and chief operating officer of NFP, will be appointed CEO when Jessica M.
