Recent Accounting Pronouncements	Recent Accounting Pronouncements In August 2015, the FASB issued ASU 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date, which deferred the effective date of ASU 2014-09. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606): Summary and Amendments that Create Revenue from Contracts with Customers (Topic 606) and Other Assets and Deferred Costs--Contracts with Customers (Subtopic 340-40). The guidance in this Update supersedes the revenue recognition requirements in ASC Topic 605, Revenue Recognition, and most industry-specific guidance throughout the industry topics of the codification. These Updates were effective beginning January 1, 2018. Our revenue is comprised of net interest income on financial assets and financial liabilities, which is explicitly excluded from the scope of ASU 2014-09, and non-interest income. We have completed our evaluation of the impact of ASU 2014-09 on components of our non-interest income and have determined that certain components contain revenue streams which are included in the scope of these updates, such as deposit-related fees, service charges, debit card interchange fees and other charges and fees, and revenue from the sale of other real estate owned; however the adoption of these updates did not materially impact the Company’s consolidated statements of income. We adopted the guidance using the modified retrospective adoption method, and no cumulative effect adjustment to opening retained earnings was required as a result of the adoption. The guidance in these Updates may result in new disclosure requirements, which will be included in the Company’s March 31, 2018 Quarterly Report on Form 10-Q. In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments – Overall (Topic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. The Update requires investments in equity securities, except for those under the equity method of accounting, to be measured at fair value with changes in fair value recognized through net income. In addition, the Update requires separate presentation of financial assets and liabilities by measurement category, such as fair value through net income, fair value through other comprehensive income, or amortized cost on the balance sheet or in the notes to the financial statements. The Update also clarified guidance related to the valuation allowance assessment when recognizing deferred tax assets resulting from unrealized losses on available-for-sale debt securities. The Update was effective for the Company on January 1, 2018 and did not have a material impact on the Company’s consolidated statements of financial condition or our consolidated statements of income. The Company does not currently hold any equity investments. In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). The amendments in this Update revise the accounting related to lessee accounting. Under the new guidance, lessees will be required to recognize a lease liability and a right-of-use asset for all leases. The Update is effective for the Company beginning in the first quarter of 2019, with early adoption permitted. Adoption of the standard requires the use of a modified retrospective transition approach for all periods presented at the time of adoption. Based on the Company’s leases outstanding at December 31, 2017, which total less than 20 leased properties, we do not expect the new standard to have a material impact on our consolidated statements of financial condition or our consolidated statements of income, although an increase to assets and liabilities will occur at the time of adoption. The Company’s new leases and lease modifications and renewals prior to the implementation date could impact the level of materiality. In March 2016, the FASB issued ASU No. 2016-09, Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. The Update amends several aspects of the accounting for employee share-based payment transactions, including the accounting for income taxes, forfeitures, and statutory tax withholding requirements, as well as classification in the statement of cash flows. The Update was effective for the Company beginning January 1, 2017, and did not have a material effect on the Company’s income taxes or the Company’s consolidated financial statements. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments – Credit Losses (Topic 326). The Update amends guidance on reporting credit losses for assets held at amortized cost basis and available for sale debt securities. For assets held at amortized cost basis, Topic 326 eliminates the probable initial recognition threshold in current GAAP and, instead, requires an entity to reflect its current estimate of all expected credit losses. This Update affects entities holding financial assets and net investment in leases that are not accounted for at fair value through net income. The amendments affect 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 companies, the update is effective for annual periods beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption will be permitted beginning after December 15, 2018. An entity will apply the amendments in this update on a modified retrospective basis, through a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is effective. The Company has formed a cross functional committee to oversee the system, data, reporting and other considerations for the purposes of meeting the requirements of this standard. We have assessed our data and system needs and are in the process of uploading the necessary historical loan data to the software that will be used in meeting certain requirements of this standard. The Company is evaluating the impact of adopting the new guidance, including the implementation of new data systems to capture the information needed to comply with the new standard. 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 new standard is effective, but cannot yet determine the magnitude of any such one-time adjustment, or the overall impact of the new guidance on the Company’s consolidated financial statements. In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230). The Update provides guidance on how certain cash receipts and payments are presented and classified in the statement of cash flows. These items include: cash payments for debt prepayment or debt extinguishment costs; cash outflows for the settlement of zero-coupon debt instruments or other debt instruments with coupon interest rates that are insignificant; contingent consideration payments made after a business combination; proceeds from the settlement of insurance claims; proceeds from the settlement of corporate-owned life insurance policies, including bank-owned life insurance policies; and beneficial interests acquired in securitization transactions. The amendments in the Update are to be applied retrospectively. The Update was effective for the Company on January 1, 2018 and did not result in a material impact on the Company’s consolidated financial statements, including the statement of cash flows. In October 2016, the FASB issued ASU No. 2016-16, Income Taxes (Topic 740). The Update provides guidance on the accounting for the income tax consequences of intra-entity transfers of assets other than inventory. Under this guidance, companies will be required to recognize the income tax consequences of an intra-entity asset transfer when the transfer occurs. The Update was effective for the Company on January 1, 2018. The adoption of this ASU did not have a material impact on the Company’s consolidated financial statements. In January 2017, the FASB issued ASU No. 2017-01, Business Combinations - Clarifying the Definition of a Business (Topic 805). The amendments in this Update provide a more robust framework to use in determining when a set of assets and activities is a business. The amendments provide more consistency in applying the guidance, reduce the costs of application, and make the definition of a business more operable. The amendments in this Update were effective for the Company on January 1, 2018. The adoption of this new guidance must be applied on a prospective basis and did not have a material impact on the Company’s consolidated financial statements. In January 2017, the FASB issued ASU No. 2017-04, Intangibles: Goodwill and Other: Simplifying the Test for Goodwill Impairment (Topic 350). To simplify the subsequent measurement of goodwill, the amendments eliminate Step 2 from the goodwill impairment test. The annual, or interim, goodwill impairment test should be performed by comparing the fair value of a reporting unit with its carrying amount and an impairment charge should be recognized for the amount by which the carrying amount exceeds the reporting unit’s fair value. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the qualitative impairment test is necessary. The nature of and reason for the change in accounting principle should be disclosed upon transition. The amendments in this update should be adopted for annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019. Early adoption is permitted on testing dates after January 1, 2017. We are currently evaluating the impact of adopting the new guidance, including consideration of early adoption, on the consolidated financial statements, but it is not expected to have a material impact. In March 2017, the FASB issued ASU No. 2017-08, Premium Amortization on Purchased Callable Debt Securities. The amendment shortens the amortization period for the premium on certain purchased callable debt securities to the earliest call date, rather than the contractual life of the security, which is typically used under current GAAP. The new guidance does not change the accounting for purchased callable debt securities held at a discount; the discount continues to be amortized to maturity. The amendments in this Update were to become effective for the Company for interim and annual reporting periods beginning after December 15, 2018; however, early adoption is permitted, and the Company elected to early adopt the ASU effective January 1, 2017. The adoption of the ASU did not have a material impact on the Company’s consolidated financial statements. In May 2017, the FASB issued ASU 2017-09, Compensation --Stock Compensation (Topic 718): Scope of Modification Accounting. The amendment provides guidance on determining which changes to the terms and conditions of share-based payment awards require an entity to apply modification accounting under Topic 7l8. The amendments clarify that modification accounting only applies to an entity if the fair value, vesting conditions, or classification of the award changes as a result of changes in the terms or conditions of a share-based payment award. The ASU should be applied prospectively to awards modified on or after the adoption date. The guidance was effective for the Company on January 1, 2018. The adoption of the ASU did not impact the Company’s consolidated financial statements. In August 2017, the FASB issued ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities. The objective of ASU 2017-12 is to improve the financial reporting of hedging relationships by better aligning an entity's risk management activity with the economic objectives in undertaking those activities. In addition, the amendments in this update simplify the application of hedge accounting for preparers of financial statements, as well as improve the understandability of an entity's risk management activities being conveyed to financial statement users. The new guidance becomes effective for periods beginning after December 15, 2018. Early adoption is permitted. The Company is currently evaluating the new guidance and timing of adoption to determine the impact this standard may have on its financial statements. In February 2018, the FASB issued ASU 2018-02, Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income (Topic 220). The amendment allows an entity to elect to reclassify the stranded tax effects resulting from the change in income tax rate from H.R. 1, originally known as the “Tax Cuts and Jobs Act,” from accumulated other comprehensive income to retained earnings. The amendments in this update are effective for periods beginning after December 15, 2018. Early adoption is permitted. The Company is still reviewing the amendments in the Update; however we anticipate that we could early adopt ASU 2018-02 in the first quarter of 2018. Our stranded tax amount which will be reclassified from other comprehensive income to retained earnings at the time of adoption is estimated to be approximately $273,000.
