I would agree with that ballpark estimate although admittedly I have not had enough coffee and it is way too early in the morning to be thinking about derivative pricing.  The only caution I would make is that the fair value does not depend entirely on what is, or is not, into the money as of quarter end, but also the volatility of the underlying security as that can send options value into the stratosphere.  Especially for long-lived options, a high volatility in the underlying security can drive the valuations much higher that a simple mark-to-market calculation would imply.   Regardless, it will be a significant nine figure number.
