In Perpetuity : A 3% NSRA hidden gem in the Atlas Salt / VUL structure is the 3% NSR. A look at the numbers: Talk has now moved upwards to Atlas producing 4 million tons per annum. At a conservative price of $60 per ton, the NSR would be computed on sales of $240 million per year. 3% brings an annual revenue stream of $7 million back to VUL at no cost. Just walk out to the mailbox and pick up the check. Obviously, the buyer won't go for that, thus that annual expense only adds more value to the eventual buyout price.
