New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Description of New Accounting Pronouncements Not yet Adopted [Text Block]	Recent Accounting Pronouncements In May 2014 and at various other dates after May 2014, the FASB issued ASU 2014-09 et al. Under the new standard, a company will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration which the company expects to receive in exchange for those goods or services. ASU 2014-09 et al. does not apply to revenue associated with financial instruments such as loans and securities. On January 1, 2018, the Company adopted ASU 2014-09 et al. using the modified retrospective transition method, however no cumulative effect adjustment to opening retained earnings as of January 1, 2018 was required. For additional disclosure details, see Part I. Item 1. “Notes to Unaudited Consolidated Financial Statements - Note 1: Basis of Presentation and Summary of Significant Accounting Policies and Note 13: Revenue Recognition.” In August 2014, the FASB issued ASU 2014-15, Presentation of Financial Instruments - Going Concern (“ASU 2014-15”). ASU 2014-15 requires management to evaluate an entity’s ability to continue as a going concern within one year after the date that the financial statements are issued. Management must evaluate whether conditions and events raise substantial doubt about an entity’s ability to continue as a going concern and then whether its plans alleviate that doubt. ASU 2014-15 was effective in 2016 and management performed the required evaluation and concluded that there were no such conditions or events that raised substantial doubt about the Company’s ability to continue as a going concern. In January 2016, the FASB issued ASU 2016-01. This ASU requires equity investments to be measured at fair value with changes in fair value, net of tax, recognized in net income. As a result of implementing this standard, the Company reclassified $339 thousand in unrealized gains on available-for-sale equity investments, net of tax, from accumulated other comprehensive income to retained earnings as of January 1, 2018. Additionally, this amendment requires that entities use the exit price notion when measuring the fair value of financial instruments for disclosure purposes. As a result of implementing this standard, the Company’s updated process includes identifying a fair value for loans using the exit price notion. See Part I. Item 1. “Notes to Unaudited Consolidated Financial Statements - Note 5: Fair Value Measurements” for further details. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). This ASU update amends current lease accounting and requires all leases, other than short-term leases, to be reported on the balance sheet through the recognition of a right-of-use asset and a corresponding liability for future lease obligations. The amended guidance will be effective for fiscal years beginning after December 15, 2018, including interim periods within those annual periods and will require transition utilizing a modified retrospective approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. Early adoption of this ASU is permitted although the Company does not plan to early adopt. The Company does not anticipate a material impact to revenue or operating expenses as a result of the adoption of this ASU. The Company expects that this ASU will gross up the assets and liabilities on the balance sheet related to the lease assets and liabilities and reduce regulatory capital ratios. In March 2016, the FASB issued ASU 2016-09, Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. This update is intended to simplify several aspects of the accounting for employee share-based plans such as income tax consequences, classification of awards as either liabilities or equity on the balance sheet, and classification on the statement of cash flows. This ASU was effective for fiscal years beginning after December 15, 2016, including interim periods within those years. The Company adopted this ASU on January 1, 2017. The adoption of this ASU has resulted in, and will continue to result in, fluctuations in the Company’s earnings due to changes in the Company’s stock price between issuance date and settlement date of employee share-based transactions. In addition, the Company anticipates that certain stock options will expire unexercised, due to having no intrinsic value, and this ASU requires the previous tax benefits to be reversed. In June 2016, the FASB issued ASU 2016-13, Financial Instruments (Topic 326) (“ASU 2016-13”). This update is intended to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date. To achieve this objective, the amendments in this update replace the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. This ASU will be effective for fiscal years beginning after December 15, 2019. Early adoption is available as of the fiscal year beginning after December 15, 2018. The Company does not plan on adopting early. The impact of this ASU on the Company’s consolidated financial statements will depend on factors at the time of adoption such as the balance and type of loans on the balance sheet, the Company’s loan loss history, and various qualitative factors. In August 2016, the FASB issued ASU 2016-15. This update is intended to reduce diversity in practice in how certain transactions are classified in the statement of cash flows. This ASU was effective for the Company beginning on January 1, 2018. Early adoption was permitted, provided that all of the amendments are adopted in the same period, however the Company did not early adopt. The guidance requires application using a retrospective transition method. This ASU did not have an impact on the Company’s consolidated financial statements. In March 2017, the FASB issued ASU 2017-07. This amendment requires an employer to report the service cost component in the same line item or items as other compensation costs arising from services rendered by the pertinent employees during the period. The other components of net benefit cost are required to be presented in the income statement separately from the service cost component and outside a subtotal of income from operations, if one is presented. This ASU was effective for fiscal years beginning after December 15, 2017, and interim periods within those years. As a result of the adoption of this ASU, $181 thousand and $341 thousand, respectively, has been reclassified from salaries and employee benefits expense to other expense within the Company’s consolidated statement of operations for the three and six months ended June 30, 2017. For the three and six months ended June 30, 2018, $145 thousand and $280 thousand, respectively, is presented within other expense that would have been presented within salaries and employee benefits prior to adoption of ASU 2017-07. In March 2017, the FASB issued ASU 2017-08, Receivables—Nonrefundable Fees and Other Costs (Subtopic 310-20), Premium Amortization on Purchased Callable Debt Securities (“ASU 2017-08”). This update amends the amortization period for certain purchased callable debt securities held at a premium. The amortization period for the premium on such securities is being shortened to the earliest call date. Under current GAAP, entities generally amortize the premium as an adjustment of yield over the contractual life of the instrument. ASU 2017-08 is effective for fiscal years beginning after December 15, 2018, and interim periods within those years. Early adoption is permitted, including in an interim period. The guidance requires application using a modified retrospective transition method through a cumulative-effect adjustment to beginning retained earnings. The Company early adopted this ASU as of July 1, 2017, which had an immaterial impact on the consolidated financial statements. In August 2017, the FASB issued ASU 2017-12. The standard is intended to improve the transparency and understandability of information conveyed to financial statement users about an entity’s risk management activities by better aligning the entity’s financial reporting for hedging relationships with those risk management activities and to reduce the complexity of and simplify the application of hedge accounting by preparers. ASU No. 2017-12 is effective for interim and annual reporting periods beginning after December 15, 2018 and early adoption is permitted. The Company elected to early adopt this ASU as of January 1, 2018 with a modified retrospective transition. As a result of implementing this standard, the Company reclassified $5 thousand in unrealized losses on derivatives from accumulated other comprehensive income to retained earnings as of January 1, 2018. This ASU will provide more flexibility in the Company’s risk management activities and we believe it will enhance the Company’s ability to employ risk management strategies, while improving the transparency and understanding of those strategies for financial statement users. In February 2018, the FASB issued ASU 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. This update was issued to address a narrow-scope financial reporting issue that arose as a consequence of the change in the tax law. On December 22, 2017, the U.S. federal government enacted the Tax Act which, among other significant changes, lowers the federal corporate tax rate from 35% to 21% effective January 1, 2018. This update requires a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the enactment of the Tax Act. ASC 740 requires that the tax effects of changes in tax rates be recognized in income tax expense/ (benefit) attributable to continuing operations in the period in which the law is enacted. As a result, the tax effect of accumulated other comprehensive income does not reflect the appropriate tax rate. The amendments in this ASU eliminate the stranded tax effects associated with the change in the federal corporate income tax rate related to the Tax Act and improve the usefulness of information reported to financial statement users. This ASU is effective for fiscal years beginning after December 15, 2018, including interim periods within those years. Early adoption is permitted for public business entities for reporting periods for which financial statements have not yet been issued. The Company early adopted this ASU on December 31, 2017 and reclassified $1.5 million from accumulated other comprehensive income to retained earnings.
