INCOME TAXES
Income Tax Expense
Income tax expense was $130 million and $115 million for the three months ended September 30, 2016 and 2015, respectively, resulting in effective tax rates of 30.5% and 34.1%, respectively. Income tax expense was $357 million and $313 million for the nine months ended September 30, 2016 and 2015, respectively, resulting in effective tax rates of 31.9% and 33.5%, respectively. For the nine months ended September 30, 2016 and 2015, the effective tax rate compared favorably to the statutory rate of 35% primarily as a result of the permanent benefits from tax credits and tax-exempt income.
Deferred Tax Liability
At September 30, 2016, the Company reported a net deferred tax liability of $994 million, compared to $730 million as of December 31, 2015. The increase in the net deferred tax liability is primarily attributable to the tax effect of net unrealized gains on securities and derivatives arising during the period and the tax effect of current year timing adjustments.
