Accounting Policies [Abstract]
Significant Accounting Policies	(2) Significant Accounting Policies Allowance for Loan Losses: The allowance for loan losses is regularly reviewed by management to determine that the amount is considered adequate to absorb probable losses in the loan portfolio. If not, an additional provision is made to increase the allowance. This evaluation includes specific loss estimates on certain individually reviewed impaired loans, the pooling of commercial credits risk graded as special mention and substandard that are not individually analyzed, and general loss estimates that are based upon the size, quality, and concentration characteristics of the various loan portfolios, adverse situations that may affect a borrower’s ability to repay, and current economic and industry conditions, among other items. Those judgments and assumptions that are most critical to the application of this accounting policy are assessing the initial and on-going credit-worthiness of the borrower, the amount and timing of future cash flows of the borrower that are available for repayment of the loan, the sufficiency of underlying collateral, the enforceability of third-party guarantees, the frequency and subjectivity of loan reviews and risk ratings, emerging or changing trends that might not be fully captured in the historical loss experience, and charges against the allowance for actual losses that are greater than previously estimated. These judgments and assumptions are dependent upon or can be influenced by a variety of factors, including the breadth and depth of experience of lending officers, credit administration and the corporate loan review staff that periodically review the status of the loan, changing economic and industry conditions, changes in the financial condition of the borrower and changes in the value and availability of the underlying collateral and guarantees. Use of Estimates: To prepare financial statements in conformity with accounting principles generally accepted in the United States of America, management makes estimates and assumptions based on available information. These estimates and assumptions affect the amounts reported in financial statements and the disclosures provided, and future results could differ. The allowance for loan losses, impairment of goodwill, fair values of financial instruments, deferred taxes and pension obligations are particularly subject to change. Income Taxes: Income tax expense is based on the effective tax rate expected to be applicable for the entire year. Income tax expense is the total of the current year income tax due or refundable and the change in deferred tax assets and liabilities. Deferred tax assets and liabilities are the expected future tax amounts for the temporary differences between carrying amounts and tax basis of assets and liabilities, computed using enacted tax rates. A valuation allowance, if needed, reduces deferred tax assets to the amount expected to be realized. Business Combinations: At the date of acquisition the Company records the assets and liabilities of acquired companies on the Consolidated Balance Sheet at their fair value. The results of operations for acquired companies are included in the Company’s Consolidated Statements of Operations beginning at the acquisition date. Expenses arising from acquisition activities are recorded in the Consolidated Statements of Operations during the period incurred. Reclassifications: Some items in the prior year financial statements were reclassified to conform to the current presentation. Such reclassifications had no effect on net income or shareholders’ equity. Derivative Instruments and Hedging Activities: The Company enters into interest rate swap agreements to facilitate the risk management strategies of a small number of commercial banking customers. All derivatives are accounted for in accordance with ASC-815, Derivatives and Hedging. The Company mitigates the risk of entering into these agreements by entering into equal and offsetting swap agreements with highly rated third party financial institutions. The swap agreements are free-standing derivatives and are recorded at fair value in the Company’s consolidated balance sheets. The Company is party to master netting arrangements with its financial institution counterparties; however, the Company does not offset assets and liabilities under these arrangements for financial statement presentation purposes because the Company does not currently intend to execute a setoff with its counterparties. The master netting arrangements provide for a single net settlement of all swap agreements, as well as collateral, in the event of default on, or termination of, any one contract. Collateral, usually in the form of marketable securities, is posted by the counterparty with net liability positions in accordance with contract thresholds. Change in Accounting Principal: In March 2017, the Financial Accounting Standards Board ('FASB') issued Accounting Standards Update ('ASU') 2017-08, Receivables – Nonrefundable Fees and Other Costs (Subtopic 310-20). These amendments shorten 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. We adopted ASU 2017-08, effective January 1, 2019, which did not have a material impact on the Company’s Consolidated Financial Statements. Adoption of New Accounting Standards: Effective January 1, 2019, the Company adopted FASB ASU 2016-02, Leases, which requires the recognition of lease assets and lease liabilities by lessees for those leases classified as operating leases under previous guidance. The original guidance required application on a modified retrospective basis with the earliest period presented. In August 2018, the FASB issued ASU 2018-11, Targeted Improvements to ASC 842, which included an option to not restate comparative periods in transition and elect to use the effective date of ASC 842, Leases, as the date of initial application of transition, which we elected. As a result of the adoption of ASC 842 on January 1, 2019, we recorded both operating lease right-of-use ('ROU') assets of $2,210 and lease liabilities of $2,210. The adoption of ASC 842 had an immaterial impact on our Condensed Consolidated Statement of Earnings and Condensed Consolidated Statement of Cash Flows for the three-month period ended March 31, 2019. In addition, we elected the package of practical expedients permitted under the transition guidance within the new standard which allowed us to carry forward the historical lease classification. There was no cumulative effect adjustment to the opening balance of retained earnings required. Additional information and disclosures required by this new standard are contained in Note 17, 'Leases'. In July 2017, the FASB issued ASU 2017-11, Earnings Per Share (Topic 260), Distinguishing Liabilities from Equity (Topic 480), and Derivative and Hedging (Topic 815). The amendments in Part I of this Update change the classification analysis of certain equity-linked financial instruments (or embedded features) with down-round features. The amendments also clarify existing disclosure requirements for equity-classified instruments. The amendments in Part II of this Update recharacterize the indefinite deferral of certain provisions of Topic 480 that now are presented as pending content in the Accounting Standards Codification, to a scope exception. Those amendments do not have an accounting effect. We adopted ASU 2017-11, effective January 1, 2019, which did not have a material impact on the Company’s Consolidated Financial Statements. In August 2017, the FASB issued ASU 2017-12, Derivatives and Hedging (Topic 850), the objective of which is to improve the financial reporting of hedging relationships to better portray the economic results of an entity’s risk management activities in its financial statements. In addition, the amendments in this Update make certain targeted improvements to simplify the application and disclosure of the hedge accounting guidance in current general accepted accounting principles. We adopted ASU 2017-12, effective January 1, 2019, which did not have a material impact on the Company’s Consolidated Financial Statements. In June 2018, the FASB issued ASU 2018-07, Compensation – Stock Compensation (Topic 718), which simplified the accounting for nonemployee share-based payment transactions. The amendments in this Update expand the scope of Topic 718 to include share-based payment transactions for acquiring goods and services from nonemployees. The amendments in this Update improve the following areas of nonemployee share-based payment accounting; (a) the overall measurement objective, (b) the measurement date, (c) awards with performance conditions, (d) classification reassessment of certain equity-classified awards, (e) calculated value (nonpublic entities only), and (f) intrinsic value (nonpublic entities only). We adopted ASU 2018-07, effective January 1, 2019, which did not have a material impact on the Company’s financial statements. Effect of Newly Issued but Not Yet Effective Accounting Standards: In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses: Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”), which changes the impairment model for most financial assets. This ASU is intended to improve financial reporting by requiring timelier recording of credit losses on loans and other financial instruments held by financial institutions and other organizations. The underlying premise of ASU 2016-13 is that financial assets measured at amortized cost should be presented at the net amount expected to be collected, through an allowance for credit losses that is deducted from the amortized cost basis. The allowance for credit losses should reflect management’s current estimate of credit losses that are expected to occur over the remaining life of a financial asset. The income statement will be effected for the measurement of credit losses for newly recognized financial assets, as well as the expected increases or decreases of expected credit losses that have taken place during the period. ASU 2016-13 is effective for annual and interim periods beginning after December 15, 2019, and early adoption is permitted for annual and interim periods beginning after December 15, 2018. Management is in the process of evaluating the impact adoption of this update will have on the Company’s Consolidated Financial Statements. This process has engaged multiple area’s of the bank in evaluating loss estimation methods and application of these methods to specific segments of the loan portfolio. Management has been actively monitoring FASB developments and evaluating the use of different methods allowed. Due to continuing development of our methodology, additional time is required to quantify the affect this ASU will have on the Company’s Consolidated Financial Statements. Management plans on running parallel calculations during the year and finalizing a method or methods of adoption in time for the effective date. In January 2017, the FASB issued ASU 2017-04, Simplifying the Test for Goodwill Impairment. To simplify the subsequent measurement of goodwill, the FASB eliminated Step 2 from the goodwill impairment test. In computing the implied fair value of goodwill under Step 2, an entity had to perform procedures to determine the fair value at the impairment testing date of its assets and liabilities (including unrecognized assets and liabilities) following the procedure that would be required in determining the fair value of assets acquired and liabilities assumed in a business combination. Instead, under the amendments in this Update, 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. A public business entity that is a U.S. Securities and Exchange Commission (“SEC”) filer, such as the Company, should adopt the amendments in this Update for its annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019. The Company is currently evaluating the impact the adoption of the standard will have on the Company’s financial position or results of operations. In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework – Changes the Disclosure Requirements for Fair Value Measurements. The Update removes the requirement to disclose the amount of and reasons for transfers between Level I and Level II of the fair value hierarchy; the policy for timing of transfers between levels; and the valuation processes for Level III fair value measurements. The Update requires disclosure of changes in unrealized gains and losses for the period included in other comprehensive income (loss) for recurring Level III fair value measurements held at the end of the reporting period and the range and weighted average of significant unobservable inputs used to develop Level III fair value measurements. This Update is effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. This Update is not expected to have a significant impact on the Company’s financial statements. In October, 2018, the FASB issued ASU 2018-17, Consolidation (Topic 810), which made improvements in 1) applying the variable interest entity (VIE) guidance to private companies under common control and 2) considering indirect interests held through related parties under common control for determining whether fees paid to decision makers and service providers are variable interests. Under the amendments in this Update, a private company may elect not to apply VIE guidance to legal entities under common control (including common control leasing arrangements) if both the parent and the legal entity being evaluated for consolidation are not public business entities. In addition, indirect interests held through related parties in common control arrangements should be considered on a proportional basis for determining whether fees paid to decision makers and service providers are variable interests. For entities other than private companies, the amendments in this Update are effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. The amendments in this Update are effective for a private company for fiscal years beginning after December 15, 2020, and interim periods within fiscal years beginning after December 15, 2021. This Update is not expected to have a significant impact on the Company’s financial statements. In November, 2018, the FASB issued ASU 2018-18, Collaborative Arrangements (Topic 808), which made the following targeted improvements to generally accepted accounting principles (GAAP) for collaborative arrangements (1) clarified that certain transactions between collaborative arrangement participants should be accounted for as revenue under Topic 606 when the collaborative arrangement participant is a customer in the context of a unit of account, (2) add unit-of-account guidance in Topic 808 to align with the guidance in Topic 606 (that is, a distinct good or service) when an entity is assessing whether the collaborative arrangement or a part of the arrangement is within the scope of Topic 606, and (3) require that in a transaction with a collaborative arrangement participant that is not directly related to sales to third parties, presenting the transaction together with revenue recognized under Topic 606 is precluded if the collaborative arrangement participant is not a customer. For public business entities, such as the Company, the amendments in this Update are effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. This Update is not expected to have a significant impact on the Company’s financial statements.

This evaluation includes specific loss estimates on certain individually reviewed impaired loans, the pooling of commercial credits risk graded as special mention and substandard that are not individually analyzed, and general loss estimates that are based upon the size, quality, and concentration characteristics of the various loan portfolios, adverse situations that may affect a borrower’s ability to repay, and current economic and industry conditions, among other items.

Those judgments and assumptions that are most critical to the application of this accounting policy are assessing the initial and on-going credit-worthiness of the borrower, the amount and timing of future cash flows of the borrower that are available for repayment of the loan, the sufficiency of underlying collateral, the enforceability of third-party guarantees, the frequency and subjectivity of loan reviews and risk ratings, emerging or changing trends that might not be fully captured in the historical loss experience, and charges against the allowance for actual losses that are greater than previously estimated.

Use of Estimates: To prepare financial statements in conformity with accounting principles generally accepted in the United States of America, management makes estimates and assumptions based on available information. These estimates and assumptions affect the amounts reported in financial statements and the disclosures provided, and future results could differ. The allowance for loan losses, impairment of goodwill, fair values of financial instruments, deferred taxes and pension obligations are particularly subject to change.

Income Taxes: Income tax expense is based on the effective tax rate expected to be applicable for the entire year. Income tax expense is the total of the current year income tax due or refundable and the change in deferred tax assets and liabilities. Deferred tax assets and liabilities are the expected future tax amounts for the temporary differences between carrying amounts and tax basis of assets and liabilities, computed using enacted tax rates. A valuation allowance, if needed, reduces deferred tax assets to the amount expected to be realized.

Business Combinations: At the date of acquisition the Company records the assets and liabilities of acquired companies on the Consolidated Balance Sheet at their fair value. The results of operations for acquired companies are included in the Company’s Consolidated Statements of Operations beginning at the acquisition date. Expenses arising from acquisition activities are recorded in the Consolidated Statements of Operations during the period incurred.

Reclassifications: Some items in the prior year financial statements were reclassified to conform to the current presentation. Such reclassifications had no effect on net income or shareholders’ equity.

Derivative Instruments and Hedging Activities: The Company enters into interest rate swap agreements to facilitate the risk management strategies of a small number of commercial banking customers. All derivatives are accounted for in accordance with ASC-815, Derivatives and Hedging. The Company mitigates the risk of entering into these agreements by entering into equal and offsetting swap agreements with highly rated third party financial institutions. The swap agreements are free-standing derivatives and are recorded at fair value in the Company’s consolidated balance sheets. The Company is party to master netting arrangements with its financial institution counterparties; however, the Company does not offset assets and liabilities under these arrangements for financial statement presentation purposes because the Company does not currently intend to execute a setoff with its counterparties. The master netting arrangements provide for a single net settlement of all swap agreements, as well as collateral, in the event of default on, or termination of, any one contract. Collateral, usually in the form of marketable securities, is posted by the counterparty with net liability positions in accordance with contract thresholds.

Change in Accounting Principal:

In March 2017, the Financial Accounting Standards Board ('FASB') issued Accounting Standards Update ('ASU') 2017-08, Receivables – Nonrefundable Fees and Other Costs (Subtopic 310-20). These amendments shorten 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. We adopted ASU 2017-08, effective January 1, 2019, which did not have a material impact on the Company’s Consolidated Financial Statements.

Adoption of New Accounting Standards:

Effective January 1, 2019, the Company adopted FASB ASU 2016-02, Leases, which requires the recognition of lease assets and lease liabilities by lessees for those leases classified as operating leases under previous guidance. The original guidance required application on a modified retrospective basis with the earliest period presented. In August 2018, the FASB issued ASU 2018-11, Targeted Improvements to ASC 842, which included an option to not restate comparative periods in transition and elect to use the effective date of ASC 842, Leases, as the date of initial application of transition, which we elected. As a result of the adoption of ASC 842 on January 1, 2019, we recorded both operating lease right-of-use ('ROU') assets of $2,210 and lease liabilities of $2,210. The adoption of ASC 842 had an immaterial impact on our Condensed Consolidated Statement of Earnings and Condensed Consolidated Statement of Cash Flows for the three-month period ended March 31, 2019. In addition, we elected the package of practical expedients permitted under the transition guidance within the new standard which allowed us to carry forward the historical lease classification. There was no cumulative effect adjustment to the opening balance of retained earnings required.

Additional information and disclosures required by this new standard are contained in Note 17, 'Leases'.

In July 2017, the FASB issued ASU 2017-11, Earnings Per Share (Topic 260), Distinguishing Liabilities from Equity (Topic 480), and Derivative and Hedging (Topic 815). The amendments in Part I of this Update change the classification analysis of certain equity-linked financial instruments (or embedded features) with down-round features. The amendments also clarify existing disclosure requirements for equity-classified instruments. The amendments in Part II of this Update recharacterize the indefinite deferral of certain provisions of Topic 480 that now are presented as pending content in the Accounting Standards Codification, to a scope exception. Those amendments do not have an accounting effect. We adopted ASU 2017-11, effective January 1, 2019, which did not have a material impact on the Company’s Consolidated Financial Statements.

In August 2017, the FASB issued ASU 2017-12, Derivatives and Hedging (Topic 850), the objective of which is to improve the financial reporting of hedging relationships to better portray the economic results of an entity’s risk management activities in its financial statements. In addition, the amendments in this Update make certain targeted improvements to simplify the application and disclosure of the hedge accounting guidance in current general accepted accounting principles. We adopted ASU 2017-12, effective January 1, 2019, which did not have a material impact on the Company’s Consolidated Financial Statements.

In June 2018, the FASB issued ASU 2018-07, Compensation – Stock Compensation (Topic 718), which simplified the accounting for nonemployee share-based payment transactions. The amendments in this Update expand the scope of Topic 718 to include share-based payment transactions for acquiring goods and services from nonemployees. The amendments in this Update improve the following areas of nonemployee share-based payment accounting; (a) the overall measurement objective, (b) the measurement date, (c) awards with performance conditions, (d) classification reassessment of certain equity-classified awards, (e) calculated value (nonpublic entities only), and (f) intrinsic value (nonpublic entities only). We adopted ASU 2018-07, effective January 1, 2019, which did not have a material impact on the Company’s financial statements.

Effect of Newly Issued but Not Yet Effective Accounting Standards:

In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses: Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”), which changes the impairment model for most financial assets. This ASU is intended to improve financial reporting by requiring timelier recording of credit losses on loans and other financial instruments held by financial institutions and other organizations. The underlying premise of ASU 2016-13 is that financial assets measured at amortized cost should be presented at the net amount expected to be collected, through an allowance for credit losses that is deducted from the amortized cost basis. The allowance for credit losses should reflect management’s current estimate of credit losses that are expected to occur over the remaining life of a financial asset. The income statement will be effected for the measurement of credit losses for newly recognized financial assets, as well as the expected increases or decreases of expected credit losses that have taken place during the period. ASU 2016-13 is effective for annual and interim periods beginning after December 15, 2019, and early adoption is permitted for annual and interim periods beginning after December 15, 2018. Management is in the process of evaluating the impact adoption of this update will have on the Company’s Consolidated Financial Statements. This process has engaged multiple area’s of the bank in evaluating loss estimation methods and application of these methods to specific segments of the loan portfolio. Management has been actively monitoring FASB developments and evaluating the use of different methods allowed. Due to continuing development of our methodology, additional time is required to quantify the affect this ASU will have on the Company’s Consolidated Financial Statements. Management plans on running parallel calculations during the year and finalizing a method or methods of adoption in time for the effective date.

In January 2017, the FASB issued ASU 2017-04, Simplifying the Test for Goodwill Impairment. To simplify the subsequent measurement of goodwill, the FASB eliminated Step 2 from the goodwill impairment test. In computing the implied fair value of goodwill under Step 2, an entity had to perform procedures to determine the fair value at the impairment testing date of its assets and liabilities (including unrecognized assets and liabilities) following the procedure that would be required in determining the fair value of assets acquired and liabilities assumed in a business combination. Instead, under the amendments in this Update, 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. A public business entity that is a U.S. Securities and Exchange Commission (“SEC”) filer, such as the Company, should adopt the amendments in this Update for its annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2019. The Company is currently evaluating the impact the adoption of the standard will have on the Company’s financial position or results of operations.

In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework – Changes the Disclosure Requirements for Fair Value Measurements. The Update removes the requirement to disclose the amount of and reasons for transfers between Level I and Level II of the fair value hierarchy; the policy for timing of transfers between levels; and the valuation processes for Level III fair value measurements. The Update requires disclosure of changes in unrealized gains and losses for the period included in other comprehensive income (loss) for recurring Level III fair value measurements held at the end of the reporting period and the range and weighted average of significant unobservable inputs used to develop Level III fair value measurements. This Update is effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. This Update is not expected to have a significant impact on the Company’s financial statements.

In October, 2018, the FASB issued ASU 2018-17, Consolidation (Topic 810), which made improvements in 1) applying the variable interest entity (VIE) guidance to private companies under common control and 2) considering indirect interests held through related parties under common control for determining whether fees paid to decision makers and service providers are variable interests. Under the amendments in this Update, a private company may elect not to apply VIE guidance to legal entities under common control (including common control leasing arrangements) if both the parent and the legal entity being evaluated for consolidation are not public business entities. In addition, indirect interests held through related parties in common control arrangements should be considered on a proportional basis for determining whether fees paid to decision makers and service providers are variable interests. For entities other than private companies, the amendments in this Update are effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. The amendments in this Update are effective for a private company for fiscal years beginning after December 15, 2020, and interim periods within fiscal years beginning after December 15, 2021. This Update is not expected to have a significant impact on the Company’s financial statements.

In November, 2018, the FASB issued ASU 2018-18, Collaborative Arrangements (Topic 808), which made the following targeted improvements to generally accepted accounting principles (GAAP) for collaborative arrangements (1) clarified that certain transactions between collaborative arrangement participants should be accounted for as revenue under Topic 606 when the collaborative arrangement participant is a customer in the context of a unit of account, (2) add unit-of-account guidance in Topic 808 to align with the guidance in Topic 606 (that is, a distinct good or service) when an entity is assessing whether the collaborative arrangement or a part of the arrangement is within the scope of Topic 606, and (3) require that in a transaction with a collaborative arrangement participant that is not directly related to sales to third parties, presenting the transaction together with revenue recognized under Topic 606 is precluded if the collaborative arrangement participant is not a customer. For public business entities, such as the Company, the amendments in this Update are effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. This Update is not expected to have a significant impact on the Company’s financial statements.
