In my last segment, I mentioned a recent deal involving a Northern California company structured as a stock sale. Having tax advisors assist at the early stages helped keep the transaction on track. The next major issue was allocating the risk of business liabilities between the buyer and the seller.
Like any stock purchase transaction, liabilities of the seller stay with the business. This is often a significant disincentive to the buyer, because it must hold an entity that cannot escape its past liabilities. Two mechanisms are commonly used to alleviate the buyer’s risk.
First, a working capital cushion may be created to provide a source of funds to pay the ongoing debts of the business. The amount of the cushion is agreed in the purchase documentation. A portion of the purchase price is then held back at the closing in an escrow. The amount of net assets as of the closing is determined through a post closing audit, and the held back amounts are distributed following the audit to the buyer or seller depending on any difference between the agreed amount and the amount determined under audit.
