monthlie,

Its just to generally show that options and warrants are continuously being exercised. This could be perceived as a good thing, sometimes when you see lots of options and warrants being exercised in a company, it means the owners are anticipating some good news or an sp rise. If every 0 or W was exercised that was outstanding, it could indicate that the sentiment is high. Also its best for the holders of such to exercise these instruments at or slightly above the strike price, this limits the tax payable in the same year and if there is a substantial increase in the sp, that increase is not taxed until the holder sells, which could be in another tax year.

I didn,t take the time to do the math on how many were outstanding and how many were exercised which can be done by referring to the financials.
