If you take the above wage pool increases and subtract them out of a $6B PTIX, you get calculations like this:

2017 PTIX $5.67B PS $884M % 15.6%
2018 PTIX $5.89B PS $872M % 15.5%

TA (assuming conservatively management incentive plan cost of $250M every year)
2016 PTIX $5.59B PS $534M % 9%
2017 PTIX $5.37B PS $512M % 8.3%
2018 PTIX $5.15B PS $490M % 7.7%
