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, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606) (“ASU 2014-09”). ASU 2014-09 replaces existing revenue recognition standards and expands the disclosure requirements for revenue agreements with customers. ASU 2014-09 has been subsequently amended by additional ASUs, including ASU 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net) and ASU 2016-12, Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients, collectively, “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. Therefore, the Company’s net interest income will not be impacted by this new standard. ASU 2014-09 et. al. is effective in the first quarter of 2018. Although the Company does not anticipate any material impact of ASU 2014-09 et. al., the Company is still assessing the full impact of implementation on its consolidated financial statements and does expect additional financial statement disclosures and associated internal controls to be implemented along with the adoption of this ASU. 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. In March 2016, the FASB issued ASU 2016-09. 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. The Company adopted this ASU on January 1, 2017. The adoption of this ASU will 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 being out of the money, and this ASU requires the previous tax benefits to be reversed. For the six months ended June 30, 2017, the impact on the Company’s income tax expense related to the adoption of this ASU was a decrease of $0.1 million. 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, Statement of Cash Flows (Topic 230) (“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 is effective for fiscal years beginning after December 15, 2017, and interim periods within those years. Early adoption is permitted, provided that all of the amendments are adopted in the same period, however the Company does not plan to early adopt. The guidance requires application using a retrospective transition method. The Company does not expect that this ASU will have a significant impact on its consolidated financial statements. In January 2017, the FASB issued ASU 2017-04. This update is the result of the first phase of a two phase project by the FASB to reduce the cost and complexity of the goodwill impairment test. The objective of Phase 1 of the project, which resulted in ASU 2017-04, is to simplify how an entity is required to test goodwill for impairment by eliminating Step 2 from the goodwill impairment test. Step 2 measures a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of that goodwill. Instead, under the amendments in ASU 2017-04, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. Additionally, an entity should consider income tax effects from any tax deductible goodwill on the carrying amount of the reporting unit when measuring the goodwill impairment loss, if applicable. Under the provisions of this update, an entity still has the option to perform the qualitative assessment, or Step 0 test, for a reporting unit to determine if the quantitative impairment test is necessary. This ASU will be effective for any annual or interim goodwill impairment tests in fiscal years beginning after December 15, 2019, with early adoption permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The Company elected to early adopt this ASU as of January 1, 2017. The adoption of this ASU could increase or decrease the amount of a goodwill impairment charge should any of the Company’s reporting units with goodwill fail a Step 1 test in the future, as compared to the amount of a goodwill impairment charge under the existing standards depending on the fair value of the reporting unit’s assets. 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 did not have a significant impact on the consolidated financial statements.
