Basis of Financial Statement Presentation
Recently Adopted Accounting Pronouncement	Recently Adopted Accounting Pronouncement In March 2016, the FASB issued ASU 2016-09, “Compensation — Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting”. ASU 2016-09 includes provisions intended to simplify various aspects related to how share-based payments are accounted for and presented in the financial statements. The areas for simplification include income tax consequences, forfeitures, classification of awards as either equity or liabilities and classification on the statement of cash flows. Under the new guidance, all excess tax benefits and deficiencies that occur when an award vests, is exercised, or expires are recognized in income tax expense as discrete period items. Previously, these transactions were typically recorded directly within equity. Consistent with this change, excess tax benefits and deficiencies are no longer included within estimated proceeds when performing the calculation for diluted earnings per share. The presentation of excess tax benefits in the statement of cash flows shifted to an operating activity from the prior classification as a financing activity. ASU 2016-09 also provides an accounting policy election to recognize forfeitures of awards as they occur when estimating stock-based compensation expense rather than the previous requirement to estimate forfeitures from inception. ASU 2016-09 became effective for the Company for reporting periods after January 1, 2017. The actual effects of adoption in 2017 primarily depends upon the share price of the Company’s stock, probability of exercise of certain stock options and the magnitude of windfalls for all awards upon either vesting or exercise. The effects on earnings per share calculations and election to account for forfeitures as incurred have not been significant. Recently Issued Accounting Pronouncements (Not Yet Effective) In May 2014, the FASB issued ASU 2014-09, “Revenue from Contracts with Customers (Topic 606)”. ASU 2014-09 replaced existing revenue recognition guidance for contracts to provide goods or services to customers. The new guidance clarifies the principles for recognizing revenue and replaces nearly all existing revenue recognition guidance in U.S. GAAP. Quantitative and qualitative disclosures regarding the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers are also required. ASU 2014-09 as amended by ASU 2015-14, ASU 2016-08, ASU 2016-10, ASU 2016-12 and ASU 2016-20, is effective for interim and annual periods beginning after December 15, 2017 and is applied on either a modified retrospective or full retrospective basis. Early adoption is permitted for interim and annual periods beginning after December 15, 2016. The Company’s revenue is mainly comprised of net interest income from financial assets and liabilities and to a lesser degree, noninterest income. The scope of ASU 2014-09 explicitly excludes net interest income as well as other revenues associated with financial assets and liabilities, including loans and securities. Accordingly, the majority of the Company’s revenues will not be affected. The Company will continue to evaluate the effect that this guidance will have on other revenue streams within its scope, as well as changes in disclosures required by the new guidance. However, adoption of this standard is not expected to have a material impact on the Company’s consolidated financial statements. In January 2016, the FASB issued ASU 2016-01, “Financial Instruments — Overall (Subtopic 825-10) - Recognition and Measurement of Financial Assets and Financial Liabilities”. ASU 2016-01 (i) requires equity investments, with certain exceptions, to be measured at fair value with changes in fair value recognized in net income; (ii) simplifies the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment; (iii) eliminates the requirement for public business entities to disclose the methods and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet; (iv) requires public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes; (v) requires an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments; (vi) requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset on the balance sheet or the accompanying notes to the financial statements; and (vii) clarifies that an entity should evaluate the need for a valuation allowance on a deferred tax asset related to available-for-sale securities. For public business entities, the amendments in ASU 2016-01 are effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early application by public business entities to financial statements of fiscal years or interim periods that have not yet been issued are permitted as of the beginning of the fiscal year of adoption. While the Company is currently evaluating the impact of this standard, the Company does not expect its adoption to have a material impact on the Company’s consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842)”. Under ASU 2016-02, lessees will be required to recognize the following for all leases (with the exception of short-term leases, as defined) at the commencement date: (i) a lease liability, which is a lessee’s obligation to make lease payments arising from a lease, measured on a discounted basis; and (ii) a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. Under the new guidance, lessor accounting is largely unchanged. Public business entities should apply the amendments in ASU 2016-02 for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. Lessees (for capital and operating leases) and lessors (for sales-type, direct financing, and operating leases) must apply a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. The Company has identified certain contracts with respect to leased real estate and office equipment that are within the scope of ASU 2016-02. As a lessee in operating lease arrangements that are not considered short-tem, effective January 1, 2019, the Company expects a gross-up of its Consolidated Statements of Condition as a result of recognizing lease liabilities and right of use assets. However, it will likely not have a significant impact on the Company’s Consolidated Statements of Income and Comprehensive Income or Cash Flows but will have a minor impact on the Bank’s regulatory capital. In June 2016, the FASB issued ASU 2016-13, “Financial Instruments — Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments”. ASU 2016-13 requires an organization to measure all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. Financial institutions and other organizations will now use forward-looking information to form their credit loss estimates. Many of the loss estimation techniques applied today will still be permitted, although the inputs to those techniques will change to reflect the full amount of expected credit losses over the life of the related financial assets. Organizations will continue to use judgment to determine which loss estimation method is appropriate for their circumstances. Additionally, the ASU amends the accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration. For public business entities, ASU 2016-13 is effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. Early adoption is permitted. While the Company is still evaluating the impact on its consolidated financial statements, the Company expects that ASU 2016-13 may result in an increase in the allowance for credit losses due to the following factors: 1) the allowance for credit losses will increase to provide for expected credit losses over the remaining expected life of the loan portfolio, and will consider expected future changes in macroeconomic conditions; and 2) an allowance may be established for estimated credit losses on available-for-sale debt securities. The amount of increase will be impacted by the portfolio composition and quality, as well as the economic conditions and forecasts as of the adoption date. While the Company has begun its implementation efforts by identifying key interpretive issues, and assessing its processes and identifying the system requirements against the new guidance to determine what modifications may be required, the Company cannot yet determine the overall impact of the new standard on its consolidated financial statements. In August 2016, the FASB issued ASU 2016-15, “Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments”. ASU 2016-15 provides guidance on the classification of certain cash receipts and payments on the consolidated statement of cash flows in order to reduce diversity in practice. ASU 2016-15 is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted. Adoption of this standard is not expected to have a material impact on the Company’s consolidated financial statements. In November 2016, the FASB issued ASU 2016-18, “Statement of Cash Flows (Topic 230): Restricted Cash”. ASU 2016-18 requires entities to show the changes in the total of cash, cash equivalents, restricted cash and restricted cash equivalents in the statement of cash flows. As a result, entities will no longer present transfers between cash and cash equivalents and restricted cash and restricted cash equivalents in the statement of cash flows. ASU 2016-18 is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years, where the guidance should be applied using a retrospective transition method to each period presented. Early adoption is permitted. Adoption of this standard is not expected to have a material impact on the Company’s consolidated financial statements.
