International Video wants to make an investment.

The home-video subsidiary of Los Angeles-based Carolco Pictures is negotiating to buy a 50% stake in Lieberman Enterprises, a major national distributor of recorded music and video movies for $20.50 a share, or about $45 million, the firms said. Lieberman Enterprises is based in Minneapolis and the ownership interest under discussion is held by Chairman David Lieberman, President Harold Okinow, family members and other company executives. If final agreement is reached, the parties said, public shareholders would be offered the same cash price in a second-step transaction, possibly through a merger in the next three months.
