Please ensure that your revised disclosure states clearly that you expect the payments to be substantial and that the arrangement will reduce the cash provided by the tax savings that would otherwise have been available to you for other uses. Because the arrangement could be considered a windfall for the continuing unitholders, your disclosure at the top of the prospectus should adequately address the fact that the agreement confers significant economic benefits to the continuing unitholders and redirects cash flows to them at the expense of the rest of your shareholders. 23.
