That's a yes and no...overall future value? Agreed, very difficult. But we believe potential value to be $2.5 billion this year for COVID and $9.5 billion for COVID if I recall what Nadar told us, so we can at least try to extrapolate a bit from there as to potential value. That doesn't factor in anything else going right, such as HIV approval, cancer BTD at some point, NASH going well...you are right, for all of that, it is so hard to determine a value, as we know it's going to be sky high.
