I'd venture there's a certain political spotlight which the NC legislature consistently inserts it's self into, that could create a sticking point for some high level C-suite executive at Apple.
The news headlines out of that state can be bewildering. The Republican attempt to strip Roy Cooper of his powers as a democratically elected governor was quite an eyebrow raising moment.
As a NC resident, I strongly expect that the current legislature will quickly draw districts to ensure their ability to maintain a super-majority in both houses of the state gov.
"It is a performance-based economic development incentive program that provides annual grant disbursements for a period of up to 12 years, to new and expanding businesses based on a percentage of withholding taxes paid by new employees during each calendar year of a grant. This percentage ranges from 10% to 75% (80% for awards after October 1, 2015 in Tier 1 counties). "

As far as I can tell, they are just proposing that most (75%) of the income taxes the new Apple employees would have paid to the state will instead go to Apple. If they never have any employees, Apple gets 75% of zero.
<edit for additional info>It appears that the Apple incentive is "transformative" a classification that means the amount can raise from 75% to 100% if Apple meets the hiring targets . . .
