A large life insurer is moving ahead with efforts to integrate its own investment operations and the investment operations of a company it acquired a year ago.

Lincoln National Corp., Philadelphia, says it has merged the Lincoln Variable Insurance Product Trusts and the Jefferson Pilot Variable Fund Trusts into a new 31-fund LVIP Trust family.

Lincoln acquired Jefferson-Pilot Corp., Greensboro, N.C., in April 2006.

Lincoln uses the trust investment funds, which manage a total of $12 billion in assets, in a variety of variable universal life, variable annuity, corporate-owned life insurance and retirement plan products.

The newly merged fund family includes 4 new “target maturity funds” and a global real estate fund, Lincoln says.
