Ann: Security Purchase Plan, page-8

So, let me ask u one thing:
I recently applied for the Ent. Offer for BOQ.
my average was 6ish.
I paid via Bpay and got my shares. my average went down to 4 ish and I am now up 91.5%.
I got the additional shares on my brokerage account at 0$. (off course they are not because I paid BOQ directly)
That's the only explanation I could get in order to justify my 91.6%.
So my original question should sound like:
Is the SPP going to effect my average the same way the Ent Offer did with my BOQ shares??
If so, my average (currently 2.8) will go well below 2. thanks.
