Q,
Not at all. I probably didn't explain it very well.
The 374 increase is the net effect of all the months in the Inventory between Oct and January. Some have risen and some have fallen.
Clearly if there is a rise in the number of cases in a particular month, they are new cases. I don't think we disagree on that.
In months where the figure has fallen, it could be due to one of 2 reasons - either it was a withdrawal/denial or it was due to an approval.
If it was due to an approval, then that number should not be deducted from the number of new cases, since that is expected in the 3 months that have passed.
Say we have 3 months that were Current in October-Dec 2010 and the change in those months between the Inventories was :
100 --- (200) --- 300
The number of NEW cases is NOT 100 - 200 + 300 = 200
It is 100 + 300 = 400
The (200) represents removal of EXISTING cases, not a reduction in NEW cases.
It COULD have been a withdrawal, but we can't tell. On the balance of probability, if the date was Current, it was an approval. If the date wasn't Current, it must have been a withdrawal.
I don't think I can explain it any better than that.
I didn't take offence! I am probably guilty as charged!
