New Authoritative Accounting Guidance	Note 2. New Authoritative Accounting Guidance ASU 2018-01, “Leases (Topic 842): Land Easement Practical Expedient for Transition to Topic 842.” ASU 2018-01 provides an optional transition practical expedient for the adoption of ASU 2016-02 that, if elected, would not require an organization to reconsider their accounting for existing land easements that are not currently accounted for under the old leases standard; and clarify that new or modified land easements should be evaluated under ASU 2016-02, once an entity has adopted the new standard. ASU 2018-01 is effective for fiscal years beginning after December 15, 2018. We believe the adoption of this standard will not have a significant impact on our consolidated financial statements. ASU No. 2017-12, “Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities.” ASU No. 2017-12 refines and expands hedge accounting for both financial (e.g., interest rate) and commodity risks. Its provisions create more transparency around how economic results are presented, both on the face of the financial statements and in the footnotes. It also makes certain targeted improvements to simplify the application of hedge accounting guidance. ASU 2017-12 will be effective for public business entities for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Although management continues to evaluate the potential impact of ASU 2017-12 on our consolidated financial statements, at this time, we believe the adoption of this standard will not have a significant impact on our consolidated financial statements. ASU No. 2017-08, “Receivables—Nonrefundable Fees and Other Costs (Subtopic 310-20), Premium Amortization on Purchased Callable Debt Securities.” ASU No. 2017-08 shortens the amortization period for certain callable debt securities held at a premium. Specifically, the amendments require the premium to be amortized to the earliest call date. The amendments do not require an accounting change for securities held at a discount; the discount continues to be amortized to maturity. ASU 2017-08 will be effective for public business entities for fiscal years beginning after December 15, 2019, and interim periods within fiscal years beginning after December 15, 2020. We are currently evaluating this ASU to determine the impact on our consolidated financial statements. ASU No. 2017-04, “Intangibles – Goodwill and Other (Topic 350).” ASU 2017-04 aims to simplify the subsequent measurement of goodwill. Under these amendments, 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. The Board also eliminated the requirements for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment. An entity is required to disclose the amount of goodwill allocated to each reporting unit with a zero or negative carrying amount of net assets and still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. The amendments in this update are effective for public business entities for fiscal years beginning after December 15, 2019. Although management continues to evaluate the potential impact of ASU 2017-04 on our consolidated financial statements, at this time, we believe the adoption of this standard will not have a significant impact on our consolidated financial statements. ASU No. 2016-13, “Financial Instruments – Credit Losses (Topic 326): Assets Measured at Amortized Cost.” ASU 2016-13 requires a financial asset (or a group of financial assets) measured at amortized cost basis to be presented at the net amount expected to be collected. 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 and affects loans, debt securities, trade receivables, net investments in leases, off-balance-sheet credit exposures, reinsurance receivables, and any other financial assets not excluded from the scope that have the contractual right to receive cash. For public business entities, the amendments in this update are effective for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years. The Company has formed a CECL committee that is assessing our data and system needs. The Company has engaged a third-party vendor to assist is analyzing our data and developing a CECL model. The Company has recently met with the third-party vendor and discussed our data, in terms of what is available and potential gaps. The Company also discussed modeling standards, loan segmentation, as well as potential external inputs to supplement our historical loss history. We expect to recognize a one-time cumulative effect adjustment to the allowance for loan losses as of the beginning of the first reporting period in which the ASU is effective, but cannot yet determine the magnitude of any such one-time adjustment or the overall impact of the ASU on our consolidated financial statements. ASU No. 2016-02, “Leases (Topic 842)” requires the recognition of a right of use asset and related lease liability by lessees for leases classified as operating leases under current GAAP. Topic 842, which replaces the current guidance under Topic 840, retains a distinction between finance leases and operating leases. The recognition, measurement, and presentation of expenses and cash flows arising from a lease by a lessee also will not significantly change from current GAAP. For leases with a term of 12 months or less, a lessee is permitted to make an accounting policy election by class of underlying asset not to recognize right of use assets and lease liabilities. Topic 842 will be effective for the Company for reporting periods beginning January 1, 2019, with early adoption permitted. The Company must apply a modified retrospective transition approach for the applicable leases existing at, or entered into after, the beginning of the earliest comparative period presented in the consolidated financial statements. The modified retrospective approach would not require any transition accounting for leases that expired before the earliest comparative period presented. The Company is currently leasing seventeen properties as branch locations and is leasing certain office equipment. The adoption of ASU 2016-02 will result in increases to the Company's assets and liabilities. We are currently in the process of evaluating all of our leases for compliance with the new ASU.
