Herbalife is currently doing a tender offer for $600m in stock (~10% of their outstanding shares) that expires tomorrow, 9/19/17. The tender is for a range of prices between $60 and $68 and the current price ($67.66) is trading just above the max tender price of $68. However, the interesting part is that you get one CVR for each share of HLF that you tender. The CVR is a little unique in that it has a two year expiration, is non-transferrable, and only pays in the event that HLF is taken private over the next two years at a premium to the tender price. Given Icahn's ~25% ownership today, and based on his recent efforts to slowly take private Tropicana Entertainment, I'd view the odds of this as greater than 50%.
So, there are two ways to play this:
Option a- buy 99 shares as a PA trade in order to ensure odd-lot priority. Tender tomorrow and at the current price, you get paid $40 to own 99 CVRs.
Option b- buy more than 99 shares to make this a decent size position and then sell the returned shares post tender. Based on some of these recent tenders, such as CIT last spring (88.6% accepted for a purchase of 28.3% of shares outstanding), White Mountains 81.5% accepted for a purchase of 13.5% shares outstanding), I'd say north of 50% chance the prorata amount is 85% or below. Based on a 9% decline to the pre-tender price of $62, this probably doesn't make sense but thought I'd flag it in case anyone is going for a larger size
