This was actually stated by Smith on the call: From a balance sheet perspective, we completed the quarter with approximately $1.24 billion of cash, cash equivalents and marketable securities and $400 million of 200 -- 2015 convertible debt outstanding. This debt has early conversion features based on certain stock prices. These results are consistent with our strategy in maintaining our financial strength while progressing our medicines in development."
The provision allows for early conversion if stock stays above $63 for 20 or more days. So its safe to say that there will be more shares added over the next few weeks.
Smith commented on that in more detail in the Q&A portion of the presentation. See his response to a JMP Securities question. From the SA transcript. "then it also has a soft call feature. Sometimes people aren't aware of that, but it does have a soft call feature that if the debt trades just above $63 for 20 days out of 30, then we do have the opportunity, and we'll have the intent to convert it into equity."
