Forgive my basic question but I've been thinking about this for a while and could use some advice.

Under an asset purchase, how does a transaction work if the sellers are selling 51% and rollover the remaining portion of "equity"? I ask because in an asset purchase the buyer is acquiring the assets of the company not the equity...

Is it assumed that the sellers retain the remaining portion of equity (or interest in the case of an LLC) in the assets?
