Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Consolidated Financial Statement Presentation	Basis of Consolidated Financial Statement Presentation The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiary, the Bank, and the Bank's wholly owned subsidiary the Service Corp. All significant intercompany accounts and transactions have been eliminated in consolidation. These consolidated financial statements were prepared in accordance with instructions for Form 10-Q and Regulation S-X, and therefore, do not include all information or notes necessary for a complete presentation of financial condition, results of operations, and cash flows in conformity with accounting principles generally accepted in the United States of America ("GAAP"). In the opinion of management, all adjustments, consisting of only normal recurring adjustments or accruals, which are necessary for a fair presentation of the consolidated financial statements have been made at September 30, 2017 and for the three and nine months ended September 30, 2017 and 2016. The results of operations for the three and nine months ended September 30, 2017 are not necessarily indicative of the results which may be expected for an entire fiscal year or other interim periods. In preparing the consolidated financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the dates of the consolidated statements of financial condition and revenues and expenses for the periods then ended. Actual results could differ significantly from those estimates. A material estimate that is particularly susceptible to significant change relates to the determination of the allowance for loan losses. Management believes that the allowance for loan losses is adequate. While management uses all available information to recognize losses on loans, future additions to the allowance for loan losses may be necessary based on changes in economic conditions in the Bank's market area. In addition, various regulatory agencies, as an integral part of their examination process, periodically review the Bank's allowance for loan losses. Such agencies may require the Bank to recognize additions to the allowance for loan losses based on their judgments about information available to them at the time of their examinations. Recent Accounting Pronouncements In May 2014, the FASB issued Accounting Standards Update (ASU) No. 2014-9, Revenue from Contracts with Customers (ASU 2014-9), which supersedes nearly all existing revenue recognition guidance under GAAP. The core principle of ASU 2014-9 is to recognize revenues when promised goods or services are transferred to customers in an amount that reflects the consideration to which an entity expects to be entitled for those goods or services. ASU 2014-9 defines a five-step process to achieve this core principle and, in doing so, more judgment and estimates may be required within the revenue recognition process than are required under existing GAAP. The standard was initially effective for annual periods beginning after December 15, 2016, and interim periods therein, using either of the following transition methods: (i) a full retrospective approach reflecting the application of the standard in each prior reporting period with the option to elect certain practical expedients, or (ii) a retrospective approach with the cumulative effect of initially adopting ASU 2014-9 recognized at the date of adoption (which includes additional footnote disclosures). The Company has not yet decided on the method it will use to adopt the guidance. The FASB subsequently issued ASU 2015-14 which states that public business entities should apply the guidance in ASU 2014-9 to annual reporting periods beginning after December 31, 2017, including interim reporting periods within that reporting period. The FASB also subsequently issued ASUs Nos. 2016-8, 2016-10, 2016-12, 2016-20 and 2017-5 to augment, amend and clarify the original pronouncement. For the nine months ended September 30, 2017, approximately 98% of our revenue was comprised of interest income on financial assets and earnings on bank-owned life insurance, which are explicitly excluded from the scope of ASU 2014-09. We are still in the process of analyzing our other revenue streams that are within the scope of the guidance, primarily service fees on deposits and ATM and debit card fees, but has not yet performed an evaluation of the underlying revenue contracts, therefore we cannot make a formal assessment on the potential impact. In January 2016, the FASB issued ASU No. 2016-1, Financial Instruments - Overall. The guidance in this ASU among other things, (1) requires equity investments with certain exceptions, to be measured at fair value with changes in fair value recognized in net income, (2) simplifies the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment, (3) eliminates the requirement for public businesses 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, (4) requires public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes, (5) requires an entity to present separately in other comprehensive income the portion of the change in 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, (6) 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 (7) clarifies that an entity should evaluate the need for a valuation allowance on a deferred tax asset related to available-for-sale securities. The guidance in this ASU is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. We do not expect the adoption of this guidance to have a material impact on our consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-2, Leases (Topic 842). This ASU revises the accounting related to lessee accounting. Under the new guidance, lessees will be required to recognize a right-of-use asset and a lease liability for all leases. The new lease guidance also simplified the accounting for sale and leaseback transactions primarily due to the recognition of lease assets and lease liabilities. ASU 2016-2 is effective for the first interim period within annual periods beginning after December 15, 2018, with early adoption permitted. The standard is required to be adopted using the modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. We currently expect that upon adoption of ASU 2016-2, right-of-use assets and lease liabilities will be recognized in our consolidated statements of condition in amounts that will be material; however, we do not expect a material impact to our consolidated income statement. In March 2016, the FASB issued ASU No. 2016-9, Improvements to Employee Share-Based Payment Accounting, Compensation – Stock Compensation (Topic 718). This ASU changes several aspects of the accounting for share-based payment award transactions, including: (1) accounting and cash flow classification for excess tax benefits and deficiencies, (2) forfeitures, and (3) tax withholding requirements and cash flow classification. The standard is effective for public companies for annual and interim periods in fiscal years beginning after December 15, 2016. Early adoption is permitted for the interim or annual period provided that the entire standard is adopted. If an entity early adopts the standard in an interim period, any adjustments should be reflected as of the beginning of the fiscal year that includes that interim period. The adoption of ASU 2016-9 effective January 1, 2017, did not have a material impact on our consolidated financial statements. In June 2016, the FASB issued ASU No. 2016-13, Measurement of Credit Losses on Financial Instruments. This ASU requires credit losses on most financial assets measured at amortized cost and certain other instruments to be measured using an expected credit loss model. Under this model, entities will estimate credit losses over the entire contractual term of the instrument. The standard is effective for public companies in annual and interim periods in fiscal years beginning after December 15, 2019. Early adoption is permitted, including adoption in the interim or annual period provided that the entire standard is adopted. We are currently evaluating the impact of ASU 2016-13 on our consolidated financial statements. We have taken steps to begin preparations for implementation, such as evaluating changes to our current loss recognition model and evaluating the potential use of outside professionals for an updated model. In August 2016, the FASB issued ASU 2016-15; Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. The amendments in this Update address the following eight specific cash flow issues with the objective of reducing the existing diversity in practice: (1) debt prepayments or debt extinguishment cost (cash outflow-financing), (2) settlement of debt instruments with coupon interest rates insignificant to the effective interest rate, interest payment (cash outflow-operating), or principal payment (cash outflow-financing), (3) contingent consideration payments made soon after a business combination (cash outflow-investing), (4) proceeds from the settlement of insurance claims (classification on basis of the nature of each loss), (5) proceeds from the corporate/bank-owned life insurance, proceeds (cash inflow-investing), payments (cash outflow-investing/operating), (6) distribution received from equity method investees, cumulative earnings approach (cash inflow-investing), nature of distribution approach (cash inflow-operating/investing), (7) beneficial interest in securitization transactions, assets (noncash transaction), cash receipts from trade receivable (cash inflow-investing), (8) separately identifiable cash flows (classified based on source-financing/investing/operating). The amendments in this Update are effective for public business entities for the fiscal years beginning after December 15, 2017 and interim periods within those fiscal years. Early adoption is permitted, including adoption in an interim period. If an entity early adopts the amendments in an interim period, any adjustments should be reflected as of the beginning of the fiscal year that includes that interim period. An entity that elects early adoption must adopt all of the amendments in the same period. We do not expect the adoption of this guidance to have a material impact on our consolidated financial statements. In February 2017, FASB issued Accounting Standards Update No. 2017-7, "Compensation—Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost" ("ASU 2017-7"). To improve the consistency, transparency, and usefulness of financial information for users, the amendments in ASU 2017-7 require that an employer disaggregate the service cost component from the other components of net benefit cost and report the service cost component in the same line item or items as other compensation costs arising from services rendered by the pertinent employees during the period. It also requires the other components of net periodic pension cost and net periodic postretirement benefit cost to be presented in the income statement separately from the service cost component and outside a subtotal of income from operations, if one is presented. The amendments in ASU 2017-7 are effective for public business entities for annual periods beginning after December 15, 2017, including interim periods within those annual periods. Early adoption is permitted as of the beginning of an annual period for which financial statements (interim or annual) have not been issued or made available for issuance. The amendments in ASU 2017-7 should be applied retrospectively for the presentation of the service cost component and the other components of net periodic pension cost and net periodic postretirement benefit cost in the income statement and prospectively, on and after the effective date, for the capitalization of the service cost component of net periodic pension cost and net periodic postretirement benefit in assets. We intend to adopt ASU 2017-7 during the first quarter of 2018 and it will have no effect on our results of operations because it only impacts the presentation of certain information on the statements of income. In March 2017, FASB issued Accounting Standards Update No. 2017-8, "Receivables —Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities" ("ASU 2017-8"). ASU 2017-8 amends guidance on the amortization period of premiums on certain purchased callable debt securities. Specifically, the amendments shorten the amortization period of premiums on certain purchased callable debt securities to the earliest call date. The amendments affect all entities that hold investments in callable debt securities that have an amortized cost basis in excess of the amount that is repayable by the issuer at the earliest call date. For public business entities, the amendments in this Update are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. Early adoption is permitted, including adoption in an interim period. If an entity early adopts the amendments in an interim period, any adjustments should be reflected as of the beginning of the fiscal year that includes that interim period. An entity should apply the amendments in this Update on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption. Additionally, in the period of adoption, an entity should provide disclosures about a change in accounting principle. The effect of ASU 2017-8 would be lower interest income and a corresponding lower yield as the amortization period would be shortened. As of September 30, 2017 we do not hold any callable debt securities that were purchased at a premium. We intend to adopt ASU 2017-8 during the first quarter of 2019. In May 2017, FASB issued Accounting Standards Update No. 2017-9, "Scope of Modification Accounting," which clarifies Topic 718, "Compensation – Stock Compensation," such that an entity must apply modification accounting to changes in the terms or conditions of a share-based payment award unless all of the following criteria are met: (1) the fair value of the modified award is the same as the fair value of the original award immediately before the modification (the ASU indicates that if the modification does not affect any of the inputs to the valuation technique used to value the award, the entity is not required to estimate the value immediately before and after the modification); (2) the vesting conditions of the modified award are the same as the vesting conditions of the original award immediately before the modification; and (3) the classification of the modified award as an equity instrument or a liability instrument is the same as the classification of the original award immediately before the modification. The ASU is effective for all entities for fiscal years beginning after December 15, 2017, including interim periods within those years. Early adoption is permitted, including adoption in an interim period. We do not expect the adoption of this guidance to have a material impact on our consolidated financial statements.

Basis of Consolidated Financial Statement Presentation

The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiary, the Bank, and the Bank's wholly owned subsidiary the Service Corp. All significant intercompany accounts and transactions have been eliminated in consolidation. These consolidated financial statements were prepared in accordance with instructions for Form 10-Q and Regulation S-X, and therefore, do not include all information or notes necessary for a complete presentation of financial condition, results of operations, and cash flows in conformity with accounting principles generally accepted in the United States of America ("GAAP").

In the opinion of management, all adjustments, consisting of only normal recurring adjustments or accruals, which are necessary for a fair presentation of the consolidated financial statements have been made at September 30, 2017 and for the three and nine months ended September 30, 2017 and 2016. The results of operations for the three and nine months ended September 30, 2017 are not necessarily indicative of the results which may be expected for an entire fiscal year or other interim periods.

In preparing the consolidated financial statements, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the dates of the consolidated statements of financial condition and revenues and expenses for the periods then ended. Actual results could differ significantly from those estimates.

A material estimate that is particularly susceptible to significant change relates to the determination of the allowance for loan losses. Management believes that the allowance for loan losses is adequate. While management uses all available information to recognize losses on loans, future additions to the allowance for loan losses may be necessary based on changes in economic conditions in the Bank's market area. In addition, various regulatory agencies, as an integral part of their examination process, periodically review the Bank's allowance for loan losses. Such agencies may require the Bank to recognize additions to the allowance for loan losses based on their judgments about information available to them at the time of their examinations.

The core principle of ASU 2014-9 is to recognize revenues when promised goods or services are transferred to customers in an amount that reflects the consideration to which an entity expects to be entitled for those goods or services. ASU 2014-9 defines a five-step process to achieve this core principle and, in doing so, more judgment and estimates may be required within the revenue recognition process than are required under existing GAAP.

The Company has not yet decided on the method it will use to adopt the guidance.

The FASB subsequently issued ASU 2015-14 which states that public business entities should apply the guidance in ASU 2014-9 to annual reporting periods beginning after December 31, 2017, including interim reporting periods within that reporting period.

The FASB also subsequently issued ASUs Nos. 2016-8, 2016-10, 2016-12, 2016-20 and 2017-5 to augment, amend and clarify the original pronouncement. For the nine months ended September 30, 2017, approximately 98% of our revenue was comprised of interest income on financial assets and earnings on bank-owned life insurance, which are explicitly excluded from the scope of ASU 2014-09. We are still in the process of analyzing our other revenue streams that are within the scope of the guidance, primarily service fees on deposits and ATM and debit card fees, but has not yet performed an evaluation of the underlying revenue contracts, therefore we cannot make a formal assessment on the potential impact.

The guidance in this ASU is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. We do not expect the adoption of this guidance to have a material impact on our consolidated financial statements.

In February 2016, the FASB issued ASU No. 2016-2, Leases (Topic 842). This ASU revises the accounting related to lessee accounting. Under the new guidance, lessees will be required to recognize a right-of-use asset and a lease liability for all leases. The new lease guidance also simplified the accounting for sale and leaseback transactions primarily due to the recognition of lease assets and lease liabilities. ASU 2016-2 is effective for the first interim period within annual periods beginning after December 15, 2018, with early adoption permitted.

The standard is required to be adopted using the modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. We currently expect that upon adoption of ASU 2016-2, right-of-use assets and lease liabilities will be recognized in our consolidated statements of condition in amounts that will be material; however, we do not expect a material impact to our consolidated income statement.

In March 2016, the FASB issued ASU No. 2016-9, Improvements to Employee Share-Based Payment Accounting, Compensation – Stock Compensation (Topic 718). This ASU changes several aspects of the accounting for share-based payment award transactions, including: (1) accounting and cash flow classification for excess tax benefits and deficiencies, (2) forfeitures, and (3) tax withholding requirements and cash flow classification. The standard is effective for public companies for annual and interim periods in fiscal years beginning after December 15, 2016. Early adoption is permitted for the interim or annual period provided that the entire standard is adopted. If an entity early adopts the standard in an interim period, any adjustments should be reflected as of the beginning of the fiscal year that includes that interim period. The adoption of ASU 2016-9 effective January 1, 2017, did not have a material impact on our consolidated financial statements.

In June 2016, the FASB issued ASU No. 2016-13, Measurement of Credit Losses on Financial Instruments. This ASU requires credit losses on most financial assets measured at amortized cost and certain other instruments to be measured using an expected credit loss model. Under this model, entities will estimate credit losses over the entire contractual term of the instrument. The standard is effective for public companies in annual and interim periods in fiscal years beginning after December 15, 2019. Early adoption is permitted, including adoption in the interim or annual period provided that the entire standard is adopted. We are currently evaluating the impact of ASU 2016-13 on our consolidated financial statements. We have taken steps to begin preparations for implementation, such as evaluating changes to our current loss recognition model and evaluating the potential use of outside professionals for an updated model.

In August 2016, the FASB issued ASU 2016-15; Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. The amendments in this Update address the following eight specific cash flow issues with the objective of reducing the existing diversity in practice: (1) debt prepayments or debt extinguishment cost (cash outflow-financing), (2) settlement of debt instruments with coupon interest rates insignificant to the effective interest rate, interest payment (cash outflow-operating), or principal payment (cash outflow-financing), (3) contingent consideration payments made soon after a business combination (cash outflow-investing), (4) proceeds from the settlement of insurance claims (classification on basis of the nature of each loss), (5) proceeds from the corporate/bank-owned life insurance, proceeds (cash inflow-investing), payments (cash outflow-investing/operating), (6) distribution received from equity method investees, cumulative earnings approach (cash inflow-investing), nature of distribution approach (cash inflow-operating/investing), (7) beneficial interest in securitization transactions, assets (noncash transaction), cash receipts from trade receivable (cash inflow-investing), (8) separately identifiable cash flows (classified based on source-financing/investing/operating). The amendments in this Update are effective for public business entities for the fiscal years beginning after December 15, 2017 and interim periods within those fiscal years. Early adoption is permitted, including adoption in an interim period. If an entity early adopts the amendments in an interim period, any adjustments should be reflected as of the beginning of the fiscal year that includes that interim period. An entity that elects early adoption must adopt all of the amendments in the same period. We do not expect the adoption of this guidance to have a material impact on our consolidated financial statements.

In February 2017, FASB issued Accounting Standards Update No. 2017-7, "Compensation—Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost" ("ASU 2017-7"). To improve the consistency, transparency, and usefulness of financial information for users, the amendments in ASU 2017-7 require that an employer disaggregate the service cost component from the other components of net benefit cost and report the service cost component in the same line item or items as other compensation costs arising from services rendered by the pertinent employees during the period. It also requires the other components of net periodic pension cost and net periodic postretirement benefit cost to be presented in the income statement separately from the service cost component and outside a subtotal of income from operations, if one is presented. The amendments in ASU 2017-7 are effective for public business entities for annual periods beginning after December 15, 2017, including interim periods within those annual periods. Early adoption is permitted as of the beginning of an annual period for which financial statements (interim or annual) have not been issued or made available for issuance. The amendments in ASU 2017-7 should be applied retrospectively for the presentation of the service cost component and the other components of net periodic pension cost and net periodic postretirement benefit cost in the income statement and prospectively, on and after the effective date, for the capitalization of the service cost component of net periodic pension cost and net periodic postretirement benefit in assets. We intend to adopt ASU 2017-7 during the first quarter of 2018 and it will have no effect on our results of operations because it only impacts the presentation of certain information on the statements of income.

In March 2017, FASB issued Accounting Standards Update No. 2017-8, "Receivables —Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities" ("ASU 2017-8"). ASU 2017-8 amends guidance on the amortization period of premiums on certain purchased callable debt securities. Specifically, the amendments shorten the amortization period of premiums on certain purchased callable debt securities to the earliest call date. The amendments affect all entities that hold investments in callable debt securities that have an amortized cost basis in excess of the amount that is repayable by the issuer at the earliest call date. For public business entities, the amendments in this Update are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. Early adoption is permitted, including adoption in an interim period. If an entity early adopts the amendments in an interim period, any adjustments should be reflected as of the beginning of the fiscal year that includes that interim period. An entity should apply the amendments in this Update on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption. Additionally, in the period of adoption, an entity should provide disclosures about a change in accounting principle. The effect of ASU 2017-8 would be lower interest income and a corresponding lower yield as the amortization period would be shortened. As of September 30, 2017 we do not hold any callable debt securities that were purchased at a premium. We intend to adopt ASU 2017-8 during the first quarter of 2019.

In May 2017, FASB issued Accounting Standards Update No. 2017-9, "Scope of Modification Accounting," which clarifies Topic 718, "Compensation – Stock Compensation," such that an entity must apply modification accounting to changes in the terms or conditions of a share-based payment award unless all of the following criteria are met: (1) the fair value of the modified award is the same as the fair value of the original award immediately before the modification (the ASU indicates that if the modification does not affect any of the inputs to the valuation technique used to value the award, the entity is not required to estimate the value immediately before and after the modification); (2) the vesting conditions of the modified award are the same as the vesting conditions of the original award immediately before the modification; and (3) the classification of the modified award as an equity instrument or a liability instrument is the same as the classification of the original award immediately before the modification. The ASU is effective for all entities for fiscal years beginning after December 15, 2017, including interim periods within those years. Early adoption is permitted, including adoption in an interim period. We do not expect the adoption of this guidance to have a material impact on our consolidated financial statements.
