(c) Other-Than-Temporary Impairment Management evaluates securities for other-than-temporary impairment (“OTTI”) at least on a quarterly basis, and more frequently when economic or market conditions warrant such an evaluation. The investment securities portfolio is evaluated for OTTI by segregating the portfolio by type and applying the appropriate OTTI model. In determining OTTI for debt securities, management considers many factors, including: (1) the length of time and the extent to which the fair value has been less than cost, (2) the financial condition and near-term prospects of the issuer, (3) whether the market decline was affected by macroeconomic conditions, and (4) whether the Company has the intent to sell the debt security or more likely than not will be required to sell the debt security before its anticipated recovery. The assessment of whether any other-than-temporary decline exists involves a high degree of subjectivity and judgment and is based on the information available to management at a point in time. When OTTI occurs, the amount of the OTTI recognized in earnings depends on whether management intends to sell the security or it is more likely than not it will be required to sell the security before recovery of its amortized cost basis. If management intends to sell or it is more likely than not it will be required to sell the security before recovery of its amortized cost basis, the OTTI shall be recognized in earnings equal to the entire difference between the investment’s amortized cost basis and its fair value at the balance sheet date. If management does not intend to sell the security and it is not more likely than not that the entity will be required to sell the security before recovery of its amortized cost basis, the OTTI on debt securities shall be separated into the amount representing the credit loss and the amount related to all other factors. The amount of the total OTTI related to the credit loss is determined based on the present value of cash flows expected to be collected and is recognized in earnings. The amount of the total OTTI related to other factors is recognized in other comprehensive income, net of applicable taxes. The previous amortized cost basis less the OTTI recognized in earnings becomes the new amortized cost basis of the investment. As of June 30, 2019, the Company’s security portfolio included certain securities which were in an unrealized loss position, and are discussed below.

The Company has identified non-accrual commercial and commercial real estate loans, as well as all loans restructured under a troubled debt restructuring (“TDR”), as impaired loans. A loan is considered impaired when it is probable that the borrower will be unable to repay the loan according to the original contractual terms of the loan agreement or the loan is restructured as a TDR.

TDR’s at June 30, 2019 and December 31, 2018 are measured at the present value of estimated future cash flows using the loan’s effective rate at inception or the fair value of the underlying collateral if the loan is considered collateral dependent.

The Company has not committed to lend additional amounts to customers with outstanding loans that are classified as impaired. Interest income recognized on impaired loans was not material during the three and six months ended June 30, 2019 and 2018. As of June 30, 2019 and December 31, 2018 impaired loans included approximately $11.2 million and $11.1 million of loans in accruing status that were identified as TDR’s in accordance with regulatory guidance related to Chapter 7 bankruptcy loans, respectively. Management evaluates impairment on impaired loans on a quarterly basis. If, during this evaluation, impairment of the loan is identified, a charge off is taken at that time. As a result, as of June 30, 2019 and December 31, 2018, based upon management’s evaluation and due to the sufficiency of chargeoffs taken, none of the allowance for loan losses has been allocated to a specific impaired loan(s). The following table presents, by class, loans that were modified as TDR’s: Three months ended 6/30/2019 Three months ended 6/30/2018 New York and other states*: Number of Contracts Pre-Modification Outstanding Recorded Investment Post-Modification Outstanding Recorded Investment Number of Contracts Pre-Modification Outstanding Recorded Investment Post-Modification Outstanding Recorded Investment (dollars in thousands) Commercial: Commercial real estate 1 $ 128 128 - $ - - Real estate mortgage - 1 to 4 family: First mortgages 5 718 718 2 125 125 Home equity loans - - - - - - Home equity lines of credit 3 278 278 - - - Total 9 $ 1,124 1,124 2 $ 125 125 Florida: (dollars in thousands) Number of Contracts Pre-Modification Outstanding Recorded Investment Post-Modification Outstanding Recorded Investment Number of Contracts Pre-Modification Outstanding Recorded Investment Post-Modification Outstanding Recorded Investment Commercial: Commercial real estate - $ - - - $ - - Real estate mortgage - 1 to 4 family: First mortgages - - - - - - Home equity loans - - - - - - Home equity lines of credit - - - - - - Total - $ - - - $ - - * Includes New York, New Jersey, Vermont and Massachusetts.

The addition of these TDR’s did not have a significant impact on the allowance for loan losses. In situations where the Company considers a loan modification, management determines whether the borrower is experiencing financial difficulty by performing an evaluation of the probability that the borrower will be in payment default on any of its debt in the foreseeable future without the modification. This evaluation is performed under the Company’s underwriting policy. Generally, the modification of the terms of loans was the result of the borrower filing for bankruptcy protection. Chapter 13 bankruptcies generally include the deferral of all past due amounts for a period of generally 60 months in accordance with the bankruptcy court order. In the case of Chapter 7 bankruptcies, as previously noted, even though there is no modification of terms, the borrowers’ debt to the Company was discharged and they did not reaffirm the debt. A loan is considered to be in payment default once it is 90 days contractually past due under the modified terms. In situations involving a borrower filing for Chapter 13 bankruptcy protection, however, a loan is considered to be in payment default once it is 30 days contractually past due, consistent with the treatment by the bankruptcy court. During the three months ended June 30, 2019 and 2018 there were no TDR’s that defaulted which had been modified during the last twelve months. The following table presents, by class, TDR’s that defaulted during the six months ended June 30, 2019 and 2018 which had been modified within the last twelve months: Six months ended 6/30/2019 Six months ended 6/30/2018 New York and other states*: Number of Contracts Recorded Investment Number of Contracts Recorded Investment (dollars in thousands) Commercial: Commercial real estate - $ - - $ - Real estate mortgage - 1 to 4 family: First mortgages - - - - Home equity loans - - - - Home equity lines of credit - - 1 3 Total - $ - 1 $ 3 Florida: (dollars in thousands) Number of Contracts Recorded Investment Number of Contracts Recorded Investment Commercial: Commercial real estate - $ - - $ - Real estate mortgage - 1 to 4 family: First mortgages - - 1 72 Home equity lines of credit - - - - Total - $ - 1 $ 72 * Includes New York, New Jersey, Vermont and Massachusetts. The TDR’s that subsequently defaulted described above did not have a material impact on the allowance for loan losses. The Company categorizes non-homogenous loans into risk categories based on relevant information about the ability of borrowers to service their debt, such as: current financial information, historical payment experience, credit documentation, public information, and current economic trends, among other factors. On at least an annual basis, the Company’s loan grading process analyzes non-homogeneous loans, such as commercial and commercial real estate loans, individually by grading the loans based on credit risk. The loan grades assigned to all loan types are tested by the Company’s internal loan review department in accordance with the Company’s internal loan review policy. The Company uses the following definitions for classified loans: Special Mention Substandard Doubtful Loans not meeting the criteria above that are analyzed individually as part of the above described process are considered to be “pass” rated loans. As of June 30, 2019 and December 31, 2018, and based on the most recent analysis performed, the risk category of loans by class of loans is as follows: June 30, 2019 New York and other states*: (dollars in thousands) Pass Classified Total Commercial: Commercial real estate $ 148,331 5,219 153,550 Other 21,258 1,022 22,280 $ 169,589 6,241 175,830 Florida: (dollars in thousands) Pass Classified Total Commercial: Commercial real estate $ 14,404 - 14,404 Other 273 - 273 $ 14,677 - 14,677 Total: (dollars in thousands) Pass Classified Total Commercial: Commercial real estate $ 162,735 5,219 167,954 Other 21,531 1,022 22,553 $ 184,266 6,241 190,507 * Includes New York, New Jersey and Massachusetts.

Included in classified loans in the above tables are impaired loans of $1.3 million and 1.4 million at June 30, 2019 and December 31, 2018, respectively. For homogeneous loan pools, such as residential mortgages, home equity lines of credit, and installment loans, the Company uses payment status to identify the credit risk in these loan portfolios. Payment status is reviewed on a daily basis by the Company’s collection area and on a monthly basis with respect to determining the adequacy of the allowance for loan losses. The payment status of these homogeneous pools as of June 30, 2019 and December 31, 2018 is included in the aging of the recorded investment of the past due loans table. In addition, the total nonperforming portion of these homogeneous loan pools as of June 30, 2019 and December 31, 2018 is presented in the non-accrual loans table.

Operating Leases

Operating Leases [Abstract]
Operating Leases	(9) Operating Leases The Company adopted Topic 842 “Leases” effective January 1, 2019 and has applied the guidance to all operating leases within the scope of Topic 842 at that date. The company elected to adopt practical expedients, which among other things, does not require reassessment of lease classification. The Company has committed to rent premises used in business operations under non-cancelable operating leases and determines if an arrangement meets the definition of a lease upon inception. Operating leases are included in operating lease right-of-use (“ROU”) assets and operating lease liabilities on the Company’s balance sheets. Operating lease ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. Operating lease ROU assets and lease liabilities are recognized at the commencement date based on the present value of lease payments over the lease term. The Company’s leases do not provide an implicit rate, therefore the Company used its incremental collateralized borrowing rates commensurate with the underlying lease terms to determine present value of operating lease liabilities. Additionally, the Company does allocate the consideration between lease and non-lease components. The Company’s lease terms may include options to extend when it is reasonably certain that the Company will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term. Variable lease components, such as fair market value adjustments, are expensed as incurred and not included in ROU assets and operating lease liabilities. Leases with an initial term of 12 months or less are not recorded on the balance sheet; we recognize lease expense for these leases on a straight-line basis over the lease term. As of January 1, 2019 the Company did not have any leases with terms of twelve months or less. As of June 30, 2019 the Company does not have leases that have not yet commenced. At June 30, 2019 lease expiration dates ranged from five months to 25.3 years and have a weighted average remaining lease term of 9.6 years.

Regulatory Capital Requirements

Regulatory Capital Requirements [Abstract]
Regulatory Capital Requirements	(10) Regulatory Capital Requirements Banks and bank holding companies are subject to regulatory capital requirements administered by federal banking agencies. Capital adequacy regulations and, additionally for banks, the prompt corrective action regulations, involve quantitative measures of assets, liabilities, and certain off-balance-sheet items calculated under regulatory accounting practices. Capital amounts and classifications are also subject to qualitative judgments by regulators. Failure to meet capital requirements can result in regulatory action. The final rules implementing Basel Committee on Banking Supervision’s capital guidelines for U.S. banks (Basel III rules) became effective for the Company on January 1, 2015 with full compliance with all of the requirements being phased in over a multi-year schedule, and became fully phased in on January 1, 2019. The capital rules include a capital conservation buffer that is designed to absorb losses during periods of economic stress and to require increased capital levels before capital distributions and certain other payments can be made. Failure to meet the full amount of the buffer will result in restrictions on the Company’s ability to make capital distributions, including dividend payments and stock repurchases, and to pay discretionary bonuses to executive officers. The buffer was fully implemented at 2.5% as of January 1, 2019. Management believes, as of June 30, 2019, the Company and Bank meet all capital adequacy requirements to which they are subject. Prompt corrective action regulations provide five classifications: well capitalized, adequately capitalized, undercapitalized, significantly undercapitalized, and critically undercapitalized, although these terms are not used to represent overall financial condition. If a bank is not classified as well capitalized, regulatory approval is required to accept brokered deposits. If a bank is undercapitalized, capital distributions are limited, as is asset growth and expansion, and capital restoration plans are required. The federal banking agencies are required to take certain supervisory actions (and may take additional discretionary actions) with respect to an undercapitalized institution or its holding company. Such actions could have a direct material effect on an institution’s or its holding company’s financial statements. As of June 30, 2019 and December 31, 2018, the most recent regulatory notifications categorized the Bank as well capitalized under the regulatory framework for prompt corrective action. There are no conditions or events since that notification that management believes have changed the Bank’s category. The Bank and the Company reported the following capital ratios as of June 30, 2019 and December 31, 2018: (Bank Only) As of June 30, 2019 Well Capitalized (1) Adequately Capitalized (1)(2) (dollars in thousands) Amount Ratio Tier 1 leverage capital $ 501,685 9.685 % 5.000 % 4.000 % Common equity tier 1 capital 501,685 18.236 6.500 7.000 Tier 1 risk-based capital 501,685 18.236 8.000 8.500 Total risk-based capital 536,199 19.491 10.000 10.500 As of December 31, 2018 Well Adequately (dollars in thousands) Amount Ratio Capitalized (1) Capitalized (1)(3) Tier 1 (core) capital $ 484,581 9.767 % 5.000 % 4.000 % Common equity tier 1 capital 484,581 18.233 6.500 6.380 Tier 1 risk-based capital 484,581 18.233 8.000 7.880 Total risk-based capital 517,948 19.489 10.000 9.880 (Consolidated) Minimum for Capital Adequacy plus Capital Conservation Buffer (1)(2) As of June 30, 2019 (dollars in thousands) Amount Ratio Tier 1 leverage capital $ 516,850 9.974 % 4.000 % Common equity tier 1 capital 516,850 18.777 7.000 Tier 1 risk-based capital 516,850 18.777 8.500 Total risk-based capital 551,383 20.031 10.500 As of December 31, 2018 Minimum for Capital Adequacy plus Capital Conservation (dollars in thousands) Amount Ratio Buffer (1)(2) Tier 1 leverage ratio $ 499,626 10.129 % 4.000 % Common equity Tier 1 capital 499,626 18.790 6.380 Tier 1 risk-based capital 499,626 18.790 7.880 Total risk-based capital 533,009 20.046 9.880 (1) Federal regulatory minimum requirements to be considered to be Well Capitalized and Adequately Capitalized (2) The June 30, 2019 common equity tier 1, tier 1 risk-based, and total risk-based capital ratios include a capital conservation buffer of 2.50 percent (3) The December 31, 2018 common equity tier 1, tier 1 risk-based, and total risk-based capital ratios include a transition capital conservation buffer of 1.88 percent

New Accounting Pronouncements [Abstract]
New Accounting Pronouncements	(11) New Accounting Pronouncements In February 2016, the FASB issued ASU No. 2016 02, Leases (Topic 842) (“ASU 2016 02”). ASU 2016 02 is intended to improve financial reporting of leasing transactions by requiring organizations that lease assets to recognize assets and liabilities for the rights and obligations created by leases that extend more than twelve months on the balance sheet. This accounting update also requires additional disclosures surrounding the amount, timing, and uncertainty of cash flows arising from leases. ASU 2016 02 is effective for financial statements issued for annual and interim periods beginning after December 15, 2018 for public business entities. Early adoption is permitted. The Company elected to adopt ASU 2016 02 as of January 1, 2019. The Company has elected the package of practical expedients permitted in ASC Topic 842. Accordingly, the Company accounted for its existing operating leases as operating leases under the new guidance, without reassessing (a) whether the contracts contain a lease under ASC Topic 842, (b) whether classification of the operating leases would be different in accordance with ASC Topic 842, or (c) whether the unamortized initial direct costs before transition adjustments (as of December 31, 2018) would have met the definition of initial direct costs in ASC Topic 842 at lease commencement. The company has also elected the practical expedient to use hindsight in determining the lease term. As a result of the adoption of the new lease accounting guidance, the Company recognized on January 1, 2019 (a) a lease liability of approximately $58.2 million, which represents the present value of the remaining lease payments of approximately $69.4 million, discounted using the Company’s incremental borrowing rate, and (b) a ROU asset of approximately $53.0 million which represents the lease liability of $58.2 million adjusted for accrued rent of approximately $5.2 million. This standard did not have a material impact on the Company’s key performance metrics and had no impact on the Company’s operating results. The most significant impact was the recognition of ROU assets and lease liabilities for operating leases. In June 2016, the FASB released ASU 2016-13, “Financial Instruments – Credit Losses” which amended existing guidance to replace current generally accepted accounting principles used to measure a reporting entity’s credit losses. The main objective of this update is to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date. To achieve this objective, the amendments in this update replace the incurred loss impairment methodology in current 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. These amendments are effective for public business entities for annual periods and interim periods within those annual periods beginning after December 15, 2019. The ASU represents a significant departure from current GAAP and the Company is evaluating the impact of the ASU on its consolidated financial statements, which includes developing a roadmap for implementation of the new standard. The Company’s committee meets regularly to evaluate the provisions of the ASU, to address the additional data requirements necessary, to determine the approach for implementation and to identify new internal controls over enhanced processes that will be put into place for estimating the allowance under ASU 2016-13. To date, the Company has completed a detailed implementation plan with a software solution to serve as its CECL platform. The Company is developing models for default and loss estimates, documenting processes, controls and accounting policy elections for the execution of “trial” or “parallel” runs of its ASU 2016-13 compliant methodology throughout 2019. In February 2018, the FASB issued ASU 2018-02, “Income statement – Reporting Comprehensive Income (Topic 220) Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income” which will allow a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act. These amendments are effective for all entities for fiscal years beginning after December 15, 2018. For Interim periods within those fiscal years, early adoption of the amendment is permitted including public business entities for reporting periods for which financial statements have not yet been issued. The Company did adopt the ASU in the first quarter of 2018 and reclassified the stranded tax effect in accumulated other comprehensive income to retained earnings in the period ended March 31, 2018. In April 2019, Accounting Standards Update No. 2019-04 “Codification improvements to topic 326 Financial Instruments-Credit Losses, Topic 815 Derivatives and Hedging, and Topic 825, “Financial Instruments” (“ASU 2019-04”) was issued to provide additional clarification on the scope and disclosure requirements of Topic 326, ASU 2019-04 includes provisions related to accounting policy elections that can be made by the entity related to accrued interest receivable and expected prepayments on financial assets, the inclusion of recoveries in estimating the allowance for credit losses and consideration of contract extension and renewals when determining the contractual term. This ASU also provides clarification on the tabular vintage disclosures related to line-of-credit arrangements that convert term loans. The Company currently writes off the uncollectible accrued interest receivable balance upon nonaccrual status by reversing interest income. The company currently includes recoveries in estimating the allowance for credit losses and is evaluating all other components of the update and their impacts to the Company effective December 15, 2019. In May 2019, Accounting Standards update No. 2019-05, “Financial Instruments – Credit Losses ( Topic 326);Targeted transition relief” (“ASU 2019-05”) was issued to allow an entity to make an irrevocable fair value option election on instruments within the scope of Topic 326 that are measured at amortized cost, except for Held-to-maturity debt securities. This election can be applied on all instrument-by instrument basis upon adoption of Topic 326. The Company is currently reviewing the impacts of the update to the Company effective December 15, 2019.
