For me to be interested in arb'ing the merger (acquisition of the CVR), you would have to be able to buy GENZ for less than 74 with closing of the deal expected in less than one month. Said another way, I would take the CVR's for free but would not pay anything significant for them.
Although SNY’s buyback price is a premium to the $1.40 price where the Genzyme CVR (ticker: GCVRZ) have been trading lately, it is a small fraction of the $13 potential CVR value attributable to Lemtrada: $1 for FDA approval and $12 for sales-based milestones as detailed in #msg-59975091.
p.s. In the prologue of #msg-59975091, I noted that it was unlikely the Lemtrada portion of the CVR would ever amount to more than $3 (including the $1 for FDA approval).
