____________________________

(1)

The Tax Cuts and Jobs Act of 2017 resulted in a change in the federal statutory corporate rate from 35% to 21%, effective January 1, 2018. Accordingly, we reduced deferred tax liabilities and recorded a deferred tax benefit in the amount of $210.6 million as of December 31, 2017 due to a remeasurement of deferred tax liabilities. Of this amount, $185.7 million was related to ENLC’s standalone deferred tax liabilities, and $24.9 million was related to ENLK’s re-measurement of deferred tax liabilities of its wholly-owned corporate subsidiaries.


(2)	Related to tax deficiencies recorded upon the vesting of restricted incentive units.
