Intervention Averts Unintended Taxable Merger

Two outside law firms designed a business combination as a tax-free merger. One of the business owners was an estate-planning client of Husch Blackwell. The night before the transaction was to close, that client called his estate-planning attorney at this firm to advise him of a change in his estate and the need for an update to his estate plan. The estate-planning attorney asked for a copy of the transaction documents in order to share them with Ray, whereupon Ray discovered that the merger would be taxable. As structured, the client would have had to pay significantly more income taxes in the year of the transaction than the amount of cash he would receive that year as a result of the transaction. That evening, Ray restructured the transaction in a manner that met both our client’s and the buyers’ goals and was completely tax free.
