Income Taxes

Note 14 — Income Taxes

The Tax Cut and Jobs Act (the “Tax Act”) enacted in December 2017 reduced the federal corporate marginal income tax rate from 35% to 21% effective January 1, 2018. As a result of the Tax Act, we recorded a $14.6 million reduction in the value of our net deferred tax asset, which was recorded as additional income tax expense in the fourth quarter of 2017 and which increased significantly the effective tax rate for the year ended December 31, 2017. We reported net deferred tax assets of $28.8 million and $48.2 million at December 31, 2017 and 2016, respectively, which related primarily to our allowance for credit losses, and loan origination fees. Adjustments may be made in future periods to these estimates as we continue to obtain, prepare and analyze information about facts and circumstances that existed as of the enactment date of the 2017 Tax Act, if known, would have affected the income tax effects reported as provisional amounts until the filling of the 2017 tax returns which is expected in the third quarter of 2018. Management believes it is more likely than not that all of the deferred tax assets will be realized. Federal and state income tax expense consists of the following for the years ended December 31:

(dollars in thousands)	2017		2016			2015
Current federal income tax expense	$	59,019	$	53,290		$	46,758
Current state income tax expense	7,511		13,733			11,020
Total current tax expense	66,530		67,023			57,778
Deferred federal income tax expense (benefit)	18,459		(5,523		)	(6,642		)
Deferred state income tax expense (benefit)	515		(105		)	(87		)
Total deferred tax expense (benefit)	18,974		(5,628		)	(6,729		)
Total income tax expense	$	85,504	$	61,395		$	51,049

Temporary timing differences between the amounts reported in the financial statements and the tax bases of assets and liabilities result in deferred taxes. The accounting for the changes in tax law resulted in stranded tax effects within accumulated other comprehensive income for items that were originally recognized in other comprehensive income rather than in net income. The FASB recently issued an accounting standard update allowing companies to reclassify stranded tax effects resulting from the Tax Act from accumulated other comprehensive income to retained earnings. The table below summarizes significant components of our deferred tax assets and liabilities utilizing federal corporate income tax rates of 21% as of December 31, 2017 and 35% as of December 31, 2016 and 2015:
