Hi Khn:
Corporate transaction agreements generally contain provisions dealing with the treatment of employee benefits plans. I would first look at the reps and warranties dealing with employee benefits in the transaction agreement to determine if the parties have already decided on what actions they wish to take with respect to the seller's 401(k) plan. In general, post-transaction, the employees of the seller are deemed to have "terminated" from the controlled group that sponsored the 401(k) plan. This results in a distribution event under the 401(k) plan. Those participants may receive their account balances in any form that is otherwise available to them under the plan, as if they had terminated employment. The important point here is that the parties cannot require the participant to roll over their account balance to the buyer's 401(k) plan. On the other hand, the parties could decide in the corporate transaction agreement to "spin-off" the account balances of those employees of the selling company that is to be acquired, and have those spun-off assets merged into the buying company's 401(k) plan. In such event, the participant's are not really given a choice--their account balances are now part of the buyer's 401(k) plan (i.e., no distribution event). Hope this helps.,
