New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements Accounting Standards Adopted in 2018 In February 2018, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2018-02, Income Statement-Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. On December 22, 2017, the Tax Cuts and Jobs Act of 2017 was signed into law, which among other things reduced the maximum federal corporate tax rate from 35% to 21%. This Update addresses concerns about the guidance in current U.S. GAAP that requires deferred tax liabilities and assets to be adjusted for the effect of a change in tax laws or rates with the effect included in income from continuing operations in the reporting period that includes the enactment date. That guidance is applicable even in situations in which the related income tax effects of items in accumulated other comprehensive income ("AOCI") were originally recognized in other comprehensive income (rather than in income from continuing operations). As a result of the adjustment of deferred taxes being required to be included in income from continuing operations, the tax effects of items within accumulated other comprehensive income (referred to as stranded tax effects for purposes of this Update) do not reflect the appropriate tax rate. This Update allows for an election to reclass between retained earnings and AOCI the impact of the federal income tax rate change. The amendments in this Update are effective for fiscal years beginning after December 15, 2018 and interim periods within those fiscal years. Early adoption of the amendments of this Update is permitted. The Company elected to early adopt in the first quarter of 2018. Accordingly, the Company recorded an increase to AOCI and a decrease to retain earnings of approximately $82,000 for stranded tax effects on investment available for sale securities in the first quarter of 2018. In January 2017, the FASB issued ASU 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business. Under the current implementation guidance in Topic 805, there are three elements of a business-inputs, processes, and outputs. While an integrated set of assets and activities (collectively referred to as a “set”) that is a business usually has outputs, outputs are not required to be present. In addition, all the inputs and processes that a seller uses in operating a set are not required if market participants can acquire the set and continue to produce outputs. The amendments in this Update provide a screen to determine when a set is not a business. The screen requires that when substantially all of the fair value of the gross assets acquired (or disposed of) is concentrated in a single identifiable asset or a group of similar identifiable assets, the set is not a business. This screen reduces the number of transactions that need to be further evaluated. If the screen is not met, the amendments in this Update (1) require that to be considered a business, a set must include, at a minimum, an input and a substantive process that together significantly contribute to the ability to create output and (2) remove the evaluation of whether a market participant could replace missing elements. The amendments provide a framework to assist entities in evaluating whether both an input and a substantive process are present. The framework includes two sets of criteria to consider that depend on whether a set has outputs. Although outputs are not required for a set to be a business, outputs generally are a key element of a business; therefore, the Company has developed more stringent criteria for sets without outputs. Lastly, the amendments in this Update narrow the definition of the term output so that the term is consistent with how outputs are described in Topic 606. Public business entities should apply the amendments in this Update to annual periods beginning after December 15, 2017, including interim periods within those periods. The adoption of this standard did not have a material effect on the Company's operating results or financial condition. In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash. The Update requires that a statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Therefore, amounts generally described as restricted cash and restricted cash equivalents should be included with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The amendments in this Update are effective for public business entities for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. The adoption of this standard did not have a material effect on the Company's operating results or financial condition. In August 2016, the FASB issued ASU 2016-15, Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. The Update provides guidance on eight specific cash flow classification issues, which include: 1) debt prepayment or debt extinguishment costs; 2) settlement of zero-coupon debt instruments or debt with coupon interest rates that are insignificant in relation to the effective interest rate; 3) contingent consideration payments made soon after a business combination; 4) proceeds from the settlement of insurance claims; 5) proceeds from the settlement of corporate-owned life insurance policies, including bank-owned life insurance policies; 6) distributions received from equity method investments; 7) beneficial interest in securitization transactions; and 8) separately identifiable cash flows and the application of the predominance principle. The amendments in this Update are effective for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted, including adoption in an interim period; however, an entity is required to adopt all of the amendments in the same period. The amendments in this Update should be applied using a retrospective transition method to each period presented. The adoption of this standard did not have a material effect on the Company's operating results or financial condition. In January 2016, the FASB issued ASU 2016-01, Financial Instruments-Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. Changes made to the current measurement model primarily affect the accounting for equity securities with readily determinable fair values, where changes in fair value will impact earnings instead of other comprehensive income. The accounting for other financial instruments, such as loans, investments in debt securities, and financial liabilities is largely unchanged. The Update also changes the presentation and disclosure requirements for financial instruments including a requirement that public business entities use exit price when measuring the fair value of financial instruments measured at amortized cost for disclosure purposes. This Update is effective for public business entities in fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The adoption of ASU 2016-01 did not have a material effect on the Company's operating results or financial condition. In accordance with the guidance, the Company measures the fair value of financial instruments reported at amortized cost on the statement of financial condition using the exit price notion. For further details, refer to Note 10 - Fair Value of Financial instruments. ASU 2014-09, Revenue From Contracts With Customers (Topic 606), ASU 2015-14 Revenue from Contracts with Customers (Topic 606): Deferral of Effective Date, ASU 2016-08 Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net), ASU 2016-10 Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing, ASU 2016-11 Revenue Recognition (Topic 605) and Derivatives ad Hedging (Topic 815): Rescission of SEC Guidance Because of Accounting Standards Updates 2014-09 and 2014-16 Pursuant to Staff Announcements at the March 3, 2016 EITF Meeting, ASU 2016-12 Revenue from Contracts with Customers (Topic 606): Narrow-Scope Improvements and Practical Expedients, and ASU 2016-20 Revenue from Contracts with Customers (Topic 606): Technical Corrections and Improvements to Topic 606. The FASB amended existing guidance related to revenue from contracts with customers, superseding and replacing nearly all existing revenue recognition guidance, including industry-specific guidance, establishing a new control-based revenue recognition model, changing the basis for deciding when revenue is recognized over time or at a point in time, providing new and more detailed guidance on specific topics and expanding and improving disclosures about revenue. In addition, this guidance specifies the accounting for some costs to obtain or fulfill a contract with a customer. The amendments are effective for public entities for annual reporting periods beginning after December 15, 2017. The Company adopted the provisions of ASU 2014-09 and its related amendments effective January 1, 2018 utilizing the modified retrospective transition method and determined the adoption was insignificant to the financial statements. Since the impact upon adoption of ASU 2014-09 was insignificant to the financial statements, a cumulative effect adjustment to retained earnings was not deemed necessary. The Company's review of its various revenue streams indicated that approximately 97% of the Company’s revenue is out of the scope of ASU 2014-09, including all of the Company’s net interest income and a significant portion of non-interest income. For those revenue streams that are within the scope of ASU 2014-09, the Company reviewed the associated customer contracts and agreements to determine the appropriate accounting for revenues under those contracts. The Company’s review did not identify any significant changes in the timing of revenue recognition under those contracts within the scope of ASU 2014-09. Significant revenue streams that are within scope primarily relate to service charges and fees associated customer deposit accounts, as well as fees for various other services the Company provides its customers. As a result of the implementation of ASU 2014-09, the Company will conduct a detailed review of its revenue streams at least annually, or more frequently if deemed necessary. Recent Accounting Guidance Not Yet Effective In March 2017, the FASB issued ASU 2017-08, Receivables - Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchase Callable Debt Securities. The updated amends guidance on the amortization period of premiums on certain purchased callable debt securities. The amendments shorten the amortization period of premiums on purchased callable debt securities to the earliest call date. The update should be applied on a modified retrospective basis through a cumulative-effect adjustment to beginning retained earnings. The effective date of ASU 2017-08 is for interim and annual reporting periods beginning after December 15, 2018. The adoption of this standard is not expected to have a material effect on the Company's operating results or financial condition. In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The amendments replace the incurred loss impairment methodology in current U.S. 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. For public business entities, the amendment is effective for annual periods beginning after December 15, 2019 and interim period within those annual periods. The Company is currently evaluating the effects of ASU 2016-13 on its financial statements and disclosures. The Company is in the process of compiling key data elements and implementing a software model that will meet the requirements of the new guidance. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). The new standard is being issued to increase the transparency and comparability around lease obligations. Previously unrecorded off-balance sheet obligations will now be brought more prominently to light by presenting lease liabilities on the face of the balance sheet, accompanied by enhanced qualitative and quantitative disclosures in the notes to the financial statements. The Update is generally effective for public business entities in fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The Company is currently in the process of evaluating existing lease obligations and service agreements under the provisions of the new standard. This evaluation includes an assessment of the appropriate classification and related accounting of each lease agreement under the new standard, a review of applicability of the new standard to existing service agreements, and gathering all essential lease data that will facilitate the application of the new standard. Upon adoption of the new standard, the Company will record a liability representing an obligation to make future lease payments and will also record an asset representing rights to use the underlying leased assets. As of March 31, 2018, the Company believes these assets and liabilities to be recognized under the new standard will amount to less than 1% of the Company's total assets.
