New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Recently Issued Accounting Pronouncements	Recent Accounting Pronouncements Adopted in 2018 In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2014-09, Revenue from Contracts with Customers (Topic 606). In August 2015, FASB issued ASU No. 2015-14, Revenue from Contracts with Customers (Topic 606) which postponed the effective date of 2014-09. Subsequently, in March 2016, the FASB issued ASU 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations. This amendment clarifies that an entity should determine if it is the principal or the agent for each specified good or service promised in a contract with a customer. In April 2016, the FASB issued ASU No. 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing. The core principle of Topic 606 is that an entity must recognize revenue when it has satisfied a performance obligation of transferring promised goods or services to a customer. These standards were effective for interim and annual periods beginning after December 15, 2017. The Company has analyzed its sources of noninterest income to determine when the satisfaction of the performance obligation occurs and the appropriate recognition of revenue. The adoption of these ASUs did not have a material impact on the Company’s consolidated financial statements. For more discussion on this topic, see Note 12 - Revenue Recognition in this report. In January 2016, FASB issued ASU No. 2016-01, Financial Instruments - Overall, Recognition and Measurement of Financial Assets and Financial Liabilities. ASU 2016-01 requires equity investments (except those accounted for under the equity method of accounting) to be measured at fair value with changes in fair value recognized in net income. In addition, the amendments in this ASU require an entity to disclose the fair value of its financial instruments using the exit price notion. Exit price is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The amendments in this ASU were effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The Company has updated the fair value disclosure on Note 7 in this report to reflect adoption of this standard, to include using the exit price notion in the fair value disclosure of financial instruments. The adoption of ASU 2016-01 did not have a material impact on the Company’s consolidated financial statements. In August 2016, FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. This ASU addresses the appropriate classification of eight specific cash flow issues on the cash flow statement. Debt prepayment costs should be classified as an outflow for financing activities. Settlement of zero-coupon debt instruments divides the interest portion as an outflow for operating activities and the principal portion as an outflow for financing activities. Contingent consideration payments made after a business combination should be classified as outflows for financing and operating activities. Proceeds from the settlement of bank-owned life insurance policies should be classified as inflows from investing activities. Other specific areas are identified in the ASU as to the appropriate classification of the cash inflows or outflows. The amendments in this ASU were effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The Company does not currently have items on its cash flow statement that were impacted by adoption of this ASU and therefore adoption of ASU 2016-15 did not have a material impact on the Company’s consolidated financial statements. In January 2017, FASB issued ASU 2017-01, Business Combinations (Topic 805). This ASU clarifies the definition of a business to assist in determining whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The amendments in this ASU provide a screen to determine when a set of assets and activities is not a business, thereby reducing the number of transactions requiring further evaluation. If the screen is not met, the amendments in this ASU further provide a framework to evaluate if the criteria is present to qualify for a business. This ASU was effective for annual periods beginning after December 15, 2017. Adoption of ASU 2017-01 did not have a material impact on the Company’s consolidated financial statements. In May 2017, FASB issued ASU No. 2017-09, Compensation - Stock Compensation (Topic 718): Scope of Modification Accounting. The ASU was issued to provide clarity as to when to apply modification accounting when there is a change in the terms or conditions of a share-based payment award. According to this ASU, an entity should account for the effects of a modification unless the fair value, vesting conditions, and balance sheet classification of the award is the same after the modification as compared to the original award prior to the modification. This ASU was effective for reporting periods beginning after December 15, 2017. The Company has not had any modifications on share-based payment awards and therefore the adoption of ASU No. 2017-09 did not have a material impact on the Company’s consolidated financial statements. In February 2018, FASB issued ASU 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220). This ASU was issued to allow a reclassification from accumulated other comprehensive income to retained earnings from stranded tax effects resulting from the revaluation of the net deferred tax asset (“DTA”) to the new corporate tax rate of 21% as a result of the Tax Cuts and Jobs Act (“Tax Act”). This ASU is effective for reporting periods beginning after December 15, 2018, with early adoption permitted. The Company adopted this ASU as of December 31, 2017, which resulted in reclassifying a net unrealized gain from the change in tax rate with an increase to accumulated other comprehensive income and a decrease to retained earnings by $41,000, respectively. In March 2018, FASB issued ASU No. 2018-05, Income Taxes (Topic 740). This ASU was issued to provide guidance on the income tax accounting implications of the Tax Act, and allows for entities to report provisional amounts for specific income tax effects of the Act for which the accounting under Topic 740 was not yet complete but a reasonable estimate could be determined. A measurement period of one-year is allowed to complete the accounting effects under Topic 740 and revise any previous estimates reported. Any provisional amounts or subsequent adjustments included in an entity’s financial statements during the measurement period should be included in income from continuing operations as an adjustment to tax expense in the reporting period the amounts are determined. The Company adopted this ASU with the provisional adjustments as reported in the Consolidated Financial Statements included in the 2017 Form 10-K. As of June 30, 2018, the Company did not incur any adjustments to the provisional recognition. In June 2018, FASB issued ASU No. 2018-07, Compensation - Stock Compensation (Topic 718). This ASU was issued to expand the scope of Topic 718 to include share-based payment transactions for acquiring goods and services from nonemployees. Previously, these awards were recorded at the fair value of consideration received or the fair value of the equity instruments issued and was measured as the earlier of the commitment date or date performance was completed. The amendments in this ASU require the awards to be measured at the grant-date fair value of the equity instrument. This ASU is effective for fiscal years beginning after December 15, 2018, and early adoption is permitted once the entity has adopted Topic 606. The Company has adopted this ASU with the nonemployee share-based payment awards granted in June 2018, with no material impact on the Company’s consolidated financial statements. Recent Accounting Pronouncements In February 2016, FASB issued ASU No. 2016-02, Leases (Topic 842). ASU No. 2016-02 requires lessees to recognize on the balance sheet the assets and liabilities arising from operating leases. A lessee should recognize a liability to make lease payments and a right-of-use asset representing its right to use the underlying asset for the lease term. A lessee should include payments to be made in an optional period only if the lessee is reasonably certain to exercise an option to extend the lease or not to exercise an option to terminate the lease. For a finance lease, interest payments should be recognized separately from amortization of the right-of-use asset in the statement of comprehensive income. For operating leases, the lease cost should be allocated over the lease term on a generally straight-line basis. The amendments in ASU 2016-02 are effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early application of the amendments in the ASU is permitted. The effect of the adoption will depend on leases at the time of adoption. Once adopted, we expect to report higher assets and liabilities as a result of including right-of-use assets and lease liabilities related to certain banking offices under noncancelable operating lease agreements, however, based on current leases, the adoption is expected to increase our consolidated balance sheets by less than 5% and not to have a material impact on our regulatory capital ratios. In June 2016, FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326). This ASU replaces the existing incurred loss impairment methodology that recognizes credit losses when a probable loss has been incurred with new methodology where loss estimates are based upon lifetime expected credit losses. The amendments in this ASU require a financial asset that is measured at amortized cost to be presented at the net amount expected to be collected. The income statement would then reflect the measurement of credit losses for newly recognized financial assets as well as changes to the expected credit losses that have taken place during the reporting period. The measurement of expected credit losses will be based on historical information, current conditions, and reasonable and supportable forecasts that impact the collectability of the reported amount. Available-for-sale securities will bifurcate the fair value mark and establish an allowance for credit losses through the income statement for the credit portion of that mark. The interest portion will continue to be recognized through accumulated other comprehensive income or loss. The change in allowance recognized as a result of adoption will occur through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the ASU is adopted. The amendments in this ASU are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years, with early adoption permitted for fiscal years beginning after December 15, 2018. The Company is evaluating our current expected loss methodology of our loan and investment portfolios to identify the necessary modifications in accordance with this standard and expects a change in the processes and procedures to calculate the ALLL, including changes in assumptions and estimates to consider expected credit losses over the life of the loan versus the current accounting practice that utilizes the incurred loss model. A valuation adjustment to our ALLL or investment portfolio that is identified in this process will be reflected as a one-time adjustment in equity rather than earnings. We are in the process of compiling historical data that will be used to calculate expected credit losses on our loan portfolio to ensure we are fully compliant with the ASU at the adoption date and are evaluating the potential impact adoption of this ASU will have on our consolidated financial statements. The Company intends to adopt ASU 2016-13 in the first quarter of 2020, and as a result, we expect our allowance for loan losses to increase. Until our evaluation is complete, however, the magnitude of the increase will not be known. In January 2017, FASB issued ASU No. 2017-04, Intangibles - Goodwill and Other (Topic 350). This ASU simplifies the impairment calculation for subsequent measurement of goodwill by eliminating the step of comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of that goodwill. Under the amendments in this ASU, an entity will evaluate the carrying amount of a reporting unit to its fair value, as if the reporting unit had been acquired in a business combination. An impairment charge should be recognized for the amount that the carrying amount exceeds the fair value, not to exceed the amount of goodwill. The income tax effect should be considered for any tax deductible goodwill when measuring the impairment loss. The amendments in this ASU are effective for goodwill impairment tests in fiscal years beginning after December 15, 2019. Early adoption is permitted for reporting periods after January 1, 2017. The Company recognized goodwill from its recent branch acquisition and is adopting this ASU for the annual goodwill impairment test in 2018. Adoption of ASU 2017-04 is not expected to have a material impact on the Company’s consolidated financial statements. In March 2017, FASB issued ASU No. 2017-08, Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities. The ASU shortens the amortization period for certain callable debt securities held at a premium. The standard will take effect for SEC filers for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. The Company is currently evaluating its available-for-sale securities that fit the criteria of this ASU but has not yet quantified the impact. The adoption of ASU No. 2017-08 is not expected to have a material impact on the Company's consolidated financial statements. In August 2017, FASB issued ASU No. 2017-12, Derivatives and Hedging (Topic 815). This ASU was issued to provide investors better insight to an entity’s risk management hedging strategies by permitting companies to recognize the economic results of its hedging strategies in its financial statements. The amendments in this ASU permit hedge accounting for hedging relationships involving non-financial risk and interest rate risk by removing certain limitations in cash flow and fair value hedging relationships. In addition, the ASU requires an entity to present the earnings effect of the hedging instrument in the same income statement line item in which the earnings effect of the hedged item is reported. This ASU is effective for fiscal years beginning after December 15, 2018, and early adoption is permitted. The Company intends to adopt this ASU during 2018, however its current cash flow hedge will not likely be impacted by the adoption of ASU 2017-12, and consequently, is not expected to have a material impact on the Company’s consolidated financial statements.

Recent Accounting Pronouncements Adopted in 2018

In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2014-09, Revenue from Contracts with Customers (Topic 606). In August 2015, FASB issued ASU No. 2015-14, Revenue from Contracts with Customers (Topic 606) which postponed the effective date of 2014-09. Subsequently, in March 2016, the FASB issued ASU 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations. This amendment clarifies that an entity should determine if it is the principal or the agent for each specified good or service promised in a contract with a customer. In April 2016, the FASB issued ASU No. 2016-10, Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing. The core principle of Topic 606 is that an entity must recognize revenue when it has satisfied a performance obligation of transferring promised goods or services to a customer. These standards were effective for interim and annual periods beginning after December 15, 2017. The Company has analyzed its sources of noninterest income to determine when the satisfaction of the performance obligation occurs and the appropriate recognition of revenue. The adoption of these ASUs did not have a material impact on the Company’s consolidated financial statements. For more discussion on this topic, see Note 12 - Revenue Recognition in this report.

In January 2016, FASB issued ASU No. 2016-01, Financial Instruments - Overall, Recognition and Measurement of Financial Assets and Financial Liabilities. ASU 2016-01 requires equity investments (except those accounted for under the equity method of accounting) to be measured at fair value with changes in fair value recognized in net income. In addition, the amendments in this ASU require an entity to disclose the fair value of its financial instruments using the exit price notion. Exit price is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The amendments in this ASU were effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The Company has updated the fair value disclosure on Note 7 in this report to reflect adoption of this standard, to include using the exit price notion in the fair value disclosure of financial instruments. The adoption of ASU 2016-01 did not have a material impact on the Company’s consolidated financial statements.

In August 2016, FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. This ASU addresses the appropriate classification of eight specific cash flow issues on the cash flow statement. Debt prepayment costs should be classified as an outflow for financing activities. Settlement of zero-coupon debt instruments divides the interest portion as an outflow for operating activities and the principal portion as an outflow for financing activities. Contingent consideration payments made after a business combination should be classified as outflows for financing and operating activities. Proceeds from the settlement of bank-owned life insurance policies should be classified as inflows from investing activities. Other specific areas are identified in the ASU as to the appropriate classification of the cash inflows or outflows. The amendments in this ASU were effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The Company does not currently have items on its cash flow statement that were impacted by adoption of this ASU and therefore adoption of ASU 2016-15 did not have a material impact on the Company’s consolidated financial statements.

In January 2017, FASB issued ASU 2017-01, Business Combinations (Topic 805).

In March 2018, FASB issued ASU No. 2018-05, Income Taxes (Topic 740). This ASU was issued to provide guidance on the income tax accounting implications of the Tax Act, and allows for entities to report provisional amounts for specific income tax effects of the Act for which the accounting under Topic 740 was not yet complete but a reasonable estimate could be determined. A measurement period of one-year is allowed to complete the accounting effects under Topic 740 and revise any previous estimates reported. Any provisional amounts or subsequent adjustments included in an entity’s financial statements during the measurement period should be included in income from continuing operations as an adjustment to tax expense in the reporting period the amounts are determined. The Company adopted this ASU with the provisional adjustments as reported in the Consolidated Financial Statements included in the 2017 Form 10-K. As of June 30, 2018, the Company did not incur any adjustments to the provisional recognition.

In June 2018, FASB issued ASU No. 2018-07, Compensation - Stock Compensation (Topic 718). This ASU was issued to expand the scope of Topic 718 to include share-based payment transactions for acquiring goods and services from nonemployees. Previously, these awards were recorded at the fair value of consideration received or the fair value of the equity instruments issued and was measured as the earlier of the commitment date or date performance was completed. The amendments in this ASU require the awards to be measured at the grant-date fair value of the equity instrument. This ASU is effective for fiscal years beginning after December 15, 2018, and early adoption is permitted once the entity has adopted Topic 606. The Company has adopted this ASU with the nonemployee share-based payment awards granted in June 2018, with no material impact on the Company’s consolidated financial statements.

The income tax effect should be considered for any tax deductible goodwill when measuring the impairment loss. The amendments in this ASU are effective for goodwill impairment tests in fiscal years beginning after December 15, 2019. Early adoption is permitted for reporting periods after January 1, 2017. The Company recognized goodwill from its recent branch acquisition and is adopting this ASU for the annual goodwill impairment test in 2018. Adoption of ASU 2017-04 is not expected to have a material impact on the Company’s consolidated financial statements.

In March 2017, FASB issued ASU No. 2017-08, Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities. The ASU shortens the amortization period for certain callable debt securities held at a premium. The standard will take effect for SEC filers for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. The Company is currently evaluating its available-for-sale securities that fit the criteria of this ASU but has not yet quantified the impact. The adoption of ASU No. 2017-08 is not expected to have a material impact on the Company's consolidated financial statements.

In August 2017, FASB issued ASU No. 2017-12, Derivatives and Hedging (Topic 815). This ASU was issued to provide investors better insight to an entity’s risk management hedging strategies by permitting companies to recognize the economic results of its hedging strategies in its financial statements. The amendments in this ASU permit hedge accounting for hedging relationships involving non-financial risk and interest rate risk by removing certain limitations in cash flow and fair value hedging relationships. In addition, the ASU requires an entity to present the earnings effect of the hedging instrument in the same income statement line item in which the earnings effect of the hedged item is reported. This ASU is effective for fiscal years beginning after December 15, 2018, and early adoption is permitted. The Company intends to adopt this ASU during 2018, however its current cash flow hedge will not likely be impacted by the adoption of ASU 2017-12, and consequently, is not expected to have a material impact on the Company’s consolidated financial statements.
