Income Tax Disclosure [Abstract] |
Income Taxes | Note 9. Income Taxes The Tax Reform Act was enacted on December 22, 2017. The Tax Reform Act reduces the US federal corporate tax rate from 34% to 21%. At December 31, 2017, we have not completed our accounting for the tax effects of enactment of the Tax Reform Act. As described below, we have made a reasonable estimate of the effects on our existing deferred tax balances as of December 31, 2017. We re-measured all of our deferred tax assets (“DTA”) and liabilities (“DTL”) based on the rates at which they are expected to reverse in the future. We recognized an income tax expense of $0.6 million for the year ended December 31, 2017 related to adjusting our net deferred tax asset balance to reflect the new corporate tax rate. In addition, DTAs/DTLs related to AFS securities unrealized losses that were revalued as of December 31, 2017 noted above created a “stranded tax effects” in Accumulated Other Comprehensive Income (“AOCI”) due enactment of the Tax Act. The issue arose due to the nature of GAAP recognition of tax rate change effects on the AFS DTA/DTL revaluation as an adjustment to income tax provision. In February 2018, FASB issued ASU 2018-02 - Income Statement - Reporting Comprehensive Income (Topic 220). As disclosed in Note 1, the Company early adopted the provisions of the ASU 2018-02 and recorded a reclassification adjustment of $104,000 from AOCI to retained earnings for stranded tax effects related to AFS securities resulting from the newly enacted corporate tax rate. The amount of the reclassification was the difference between the 34 percent historical corporate tax rate and the newly enacted 21 percent corporate tax rate. See Statement of Changes in Stockholders Equity for additional details and reclassification impact due to impact of the ASU 2018-02. The components of income tax expense (benefit) are as follows for the years ended December 31, 2017 and 2016:
|  | 2017 |  | 2016

|  | 2017 |  | 2016 |

Management has determined that no valuation allowance is required as it believes it is more likely than not that all of the deferred tax assets will be fully realizable in the future. At December 31, 2017 and 2016, management believes there are no uncertain tax positions under ASC Topic 740 Income Taxes (formerly FIN 48, Accounting for Uncertainty in Income Taxes). Income tax expense was $0.91 million and ($0.08) million at December 2017 and 2016, respectively. Included in the 2017 was a one-time $0.60 million income tax expense due to the Tax Reform Act which required us to revalue our deferred tax assets and liabilities at the new statutory tax rate upon enactment.
