Deal perimeter

The deal perimeter is the boundary of what is being sold: which companies, businesses, assets, contracts and people go to the buyer, and which stay with the seller. It is fixed early, because the price, the due diligence and the documents all depend on it. Anything shared with the seller's group needs a plan, such as a transitional services agreement.

The precise boundary of what is being bought: which companies, assets, contracts and people are inside the deal and which stay behind with the seller. Drawing the perimeter is a structuring exercise done before the SPA is drafted — get it wrong and you buy too much or too little. Chapter 4
