While calculating weighted average, do I consider the taxes, fees and commissions in my total cost or just the actual amount that I paid per share?

Also, I have shares of NICA that was originally for Bank Of Asia that I got duing IPO. I paid 100 per share and when NIC and BOA merged, two share of BOA became 1 of NICA, so is my cost 100 per share of NICA or 200?
