After reviewing prior posts, it seems as if it is no surprise when a takeover plan document is unsigned. Has anyone come across a situation in which a company acquires another company (let’s call the other company, “Target”). Target has a signed 401(k) prototype plan. Prior to sponsoring the prototype plan, Target sponsored an individually designed plan, which was never signed. The prototype vendor used the unsigned document to create the prototype and never asked for anything more. Company wants to merge Target’s 401(k) plan into its own 401(k) plan but is concerned that Target’s prior unsigned individually designed document will taint its 401(k) plan. Should we simply ignore Target’s prior unsigned document, or is this a real concern that would justify a VCP filing?
