Hopefully your AAPL is in a non-taxable account. Otherwise you are setting yourself up for this [1]:

   If all this seems complicated -- it is. A lifetime
   of DRIP investing may create a morass of tax
   obligations when the time comes to sell the DRIP
   shares, with at least four new cost bases of DRIP
   shares established each year (when dividends are
   reinvested) as well as when any OCPs are made. 

The first time I saw my accountant he literally shook my hand when I told him I didn't do DRIP.
