I would be surprised if they have even tapped 50% of the Aspire deal. They have plenty of cash to make it well into 2015. The last PR even said it: "Simply, we have plenty of cash on hand and available to us for our planned laboratory and clinical studies, but a shelf registration with a few year term affords us the opportunity to explore other future considerations that are immediately accretive to our corporate value, whether it is additional clinical trials or an acquisition. We're under no pressure to ever exercise the registration, but it is a prudent financial move to have additional cash available to us should a unique opportunity arise."
