I suspect the real purpose of such transactions is to increase the revenues of the investment banks & law firms that sell the idea to management.
Ditto stock buybacks, which use cash to buy in shares, thus reducing both cash & stock os from the balance sheet, with the net result of reducing the overall size of the business. Lots of gravy for the investment bankers & law firms that convince management to do it. Advantage to the business firm?? smoke & mirrors.
