There were no sales or transfers of held to maturity securities during the three months and nine months ended September 30, 2016 and 2015 . (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. Investment securities classified as available for sale or held to maturity are evaluated for OTTI under ASC 320 “Investments – Debt and Equity Securities.” In determining OTTI under the FASB ASC 320 model, 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 September 30, 2016, the Company’s security portfolio included certain securities which were in an unrealized loss position. The declines in fair value are attributable to changes in interest rates, and not credit quality, and because the Company does not have the intent to sell these securities and it is likely that it will not be required to sell the securities before their anticipated recovery, the Company does not consider these securities to be other-than-temporarily impaired at September 30, 2016 .

In situations where the Bank 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. The following table presents, by class, TDR’s that defaulted during the three months and nine months ended September 30, 2016 and 2015 which had been modified within the last twelve months: Three months ended 9/30/2016 Three months ended 9/30/2015 New York and other states*: (dollars in thousands) Number of Contracts Recorded Investment Number of Contracts Recorded Investment Real estate mortgage - 1 to 4 family: First mortgages - $ - 1 $ 121 Total - $ - 1 $ 121 Florida: (dollars in thousands) Number of Contracts Recorded Investment Number of Contracts Recorded Investment Real estate mortgage - 1 to 4 family: First mortgages - $ - - $ - Total - $ - - $ - Nine months ended 9/30/2016 Nine months ended 9/30/2015 New York and other states*: (dollars in thousands) Number of Contracts Recorded Investment Number of Contracts Recorded Investment Real estate mortgage - 1 to 4 family: First mortgages 1 $ 107 1 $ 121 Total 1 $ 107 1 $ 121 Florida: (dollars in thousands) Number of Contracts Recorded Investment Number of Contracts Recorded Investment Real estate mortgage - 1 to 4 family: Home equity lines of credit 1 $ 46 1 $ 50 Total 1 $ 46 1 $ 50 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 September 30, 2016 and December 31, 2015, and based on the most recent analysis performed, the risk category of loans by class of loans is as follows: September 30, 2016 New York and other states: (dollars in thousands) Pass Classified Total Commercial: Commercial real estate $ 143,529 11,218 154,747 Other 21,372 1,171 22,543 $ 164,901 12,389 177,290 Florida: (dollars in thousands) Pass Classified Total Commercial: Commercial real estate $ 12,505 - 12,505 Other - - - $ 12,505 - 12,505 Total: (dollars in thousands) Pass Classified Total Commercial: Commercial real estate $ 156,034 11,218 167,252 Other 21,372 1,171 22,543 $ 177,406 12,389 189,795 December 31, 2015 New York and other states: (dollars in thousands) Pass Classified Total Commercial: Commercial real estate $ 145,335 15,630 160,965 Other 26,715 734 27,449 $ 172,050 16,364 188,414 Florida: (dollars in thousands) Pass Classified Total Commercial: Commercial real estate $ 14,908 - 14,908 Other 93 - 93 $ 15,001 - 15,001 Total: (dollars in thousands) Pass Classified Total Commercial: Commercial real estate $ 160,243 15,630 175,873 Other 26,808 734 27,542 $ 187,051 16,364 203,415 Included in classified loans in the above tables are impaired loans of $2.4 million and $3.0 million at September 30, 2016 and December 31, 2015, 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 Bank’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 September 30, 2016 and December 31, 2015 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 September 30, 2016 and December 31, 2015 is presented in the non-accrual loans table.

Fair Value of Financial Instruments [Abstract]
Fair Value of Financial Instruments	(6) Fair Value of Financial Instruments Fair value measurements (ASC 820) defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. ASC 820 also establishes a fair value hierarchy which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The standard describes three levels of inputs that may be used to measure fair values: Level 1 – Quoted prices (unadjusted) for identical assets or liabilities in active markets that the entity can access as of the measurement date. Level 2 – Significant other observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data. Level 3 – Significant unobservable inputs that reflect a company’s own assumptions about the value that market participants would use in pricing an asset or liability. The Company used the following methods and significant assumptions to estimate the fair value of assets and liabilities: Securities Available for Sale Other Real Estate Owned Impaired Loans Indications of value for both collateral-dependent impaired loans and other real estate owned are obtained from third party providers or the Company’s internal Appraisal Department. All indications of value are reviewed for reasonableness by a member of the Appraisal Department for the assumptions and approaches utilized in the appraisal as well as the overall resulting fair value via comparison with independent data sources such as recent market data or industry-wide statistics. Assets and liabilities measured at fair value under ASC 820 on a recurring basis are summarized below: Fair Value Measurements at September 30, 2016 Using: Carrying Value Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) (dollars in thousands) Securities available for sale: U.S. government sponsored enterprises $ 116,327 $ - $ 116,327 $ - State and political subdivisions 970 - 970 - Corporate bonds 41,025 - 41,025 - Mortgage backed securities and collateralized mortgage obligations - residential 400,575 - 400,575 - Small Business Administration- guaranteed participation securities 84,687 - 84,687 - Mortgage backed securities and collateralized mortgage obligations - commercial 10,233 - 10,233 - Other securities 685 35 650 - Total securities available for sale $ 654,502 $ 35 $ 654,467 $ - Fair Value Measurements at December 31, 2015 Using: Carrying Value Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) (dollars in thousands) Securities available for sale: U.S. government sponsored enterprises $ 86,737 $ - $ 86,737 $ - State and political subdivisions 1,290 - 1,290 - Mortgage backed securities and collateralized mortgage obligations - residential 411,729 - 411,729 - Small Business Administration- guaranteed participation securities 90,416 - 90,416 - Mortgage backed securities and collateralized mortgage obligations - commercial 10,180 - 10,180 - Other securities 685 35 650 - Total securities available for sale $ 601,037 $ 35 $ 601,002 $ - There were no transfers between Level 1 and Level 2 during the three months and nine months ended September 30, 2016 and 2015 .

Due to the sufficiency of charge offs taken on these loans and the adequacy of the underlying collateral, there were no specific valuation allowances for these loans at September 30, 2016. Gross charge offs related to commercial impaired loans included in the table above were $406 thousand for the three months and nine months ended September 30, 2016 while gross charge offs related to residential impaired loans included in the table above amounted to $0 and $4 thousand for the three months and nine months ended September 30, 2016, respectively. Other real estate owned, that is carried at fair value less costs to sell, approximates $6.4 million at December 31, 2015 and consisted of $1.0 million of commercial real estate and $5.4 million of residential real estate properties. A valuation charge of $1.1 million is included in earnings for the year ended December 31, 2015. Of the total impaired loans of $25.9 million at December 31, 2015, $4.0 million are collateral dependent and are carried at fair value measured on a non-recurring basis. Due to the sufficiency of charge offs taken on these loans and the adequacy of the underlying collateral, there were no specific valuation allowances for these loans at December 31, 2015. Gross charge offs related to commercial impaired loans included in the table above were $641 thousand for the year ended December 31, 2015, while gross charge offs related to residential impaired loans included in the table above amounted to $648 thousand. In accordance with ASC 825, the carrying amounts and estimated fair values of financial instruments, at September 30, 2016 and December 31, 2015 are as follows: (dollars in thousands) Carrying Fair Value Measurements at September 30, 2016 Using: Value Level 1 Level 2 Level 3 Total Financial assets: Cash and cash equivalents $ 664,428 664,428 - - 664,428 Securities available for sale 654,502 35 654,467 - 654,502 Held to maturity securities 48,030 - 50,991 - 50,991 Federal Reserve Bank and Federal Home Loan Bank stock 9,579 N/A N/A N/A N/A Net loans 3,343,681 - - 3,414,401 3,414,401 Accrued interest receivable 10,872 25 2,695 8,152 10,872 Financial liabilities: Demand deposits 380,090 380,090 - - 380,090 Interest bearing deposits 3,788,148 2,628,949 1,160,918 - 3,789,867 Short-term borrowings 179,204 - 179,204 - 179,204 Accrued interest payable 496 72 424 - 496 (dollars in thousands) Carrying Fair Value Measurements at December 31, 2015 Using: Value Level 1 Level 2 Level 3 Total Financial assets: Cash and cash equivalents $ 718,156 718,156 - - 718,156 Securities available for sale 601,037 35 601,002 - 601,037 Held to maturity securities 56,465 - 59,439 - 59,439 Federal Reserve Bank and Federal Home Loan Bank stock 9,480 N/A N/A N/A N/A Net loans 3,248,542 - - 3,279,167 3,279,167 Accrued interest receivable 10,262 80 2,370 7,812 10,262 Financial liabilities: Demand deposits 365,081 365,081 - - 365,081 Interest bearing deposits 3,735,297 2,627,367 1,111,240 - 3,738,607 Short-term borrowings 191,226 - 191,226 - 191,226 Accrued interest payable 501 74 427 - 501 The specific estimation methods and assumptions used can have a substantial impact on the resulting fair values of financial instruments. The following is a brief summary of the significant methods and assumptions used in estimating fair values: Cash and Cash Equivalents The carrying values of these financial instruments approximate fair values and are classified as Level 1. Federal Reserve Bank and Federal Home Loan Bank stock It is not practical to determine the fair value of Federal Reserve Bank and Federal Home Loan Bank stock due to their restrictive nature. Securities Held to Maturity Similar to securities available for sale described previously, the fair value of securities held to maturity are determined utilizing an independent pricing service for identical assets or significantly similar securities. The pricing service uses a variety of techniques to arrive at fair value including market maker bids, quotes and pricing models. Inputs to the pricing models include recent trades, benchmark interest rates, spreads and actual and projected cash flows. This results in a Level 2 classification of the inputs for determining fair value. Interest and dividend income is recorded on the accrual method and included in the Consolidated Statements of Income in the respective investment class under total interest and dividend income. The Company does not have any securities that would be designated as Level 3. Loans The fair values of all loans are estimated using discounted cash flow analyses with discount rates equal to the interest rates currently being offered for loans with similar terms to borrowers of similar credit quality resulting in a Level 3 classification. Impaired loans are valued at the lower of cost or fair value as described previously. The methods utilized to estimate the fair value of loans do not necessarily represent an exit price. Deposit Liabilities The fair values disclosed for noninterest bearing demand deposits, interest bearing checking accounts, savings accounts, and money market accounts are, by definition, equal to the amount payable on demand at the balance sheet date resulting in a Level 1 classification. The carrying value of all variable rate certificates of deposit approximates fair value resulting in a Level 2 classification. The fair value of fixed rate certificates of deposit is estimated using discounted cash flow analyses with discount rates equal to the interest rates currently being offered on certificates of similar size and remaining maturity resulting in a Level 2 classification. Accrued Interest Receivable/Payable The carrying amounts of accrued interest approximate fair value resulting in a Level 1, Level 2 or Level 3 classification consistent with the asset or liability that they are associated with. Short-Term Borrowings and Other Financial Instruments The fair value of all short-term borrowings, and other financial instruments approximates the carrying value resulting in a Level 2 classification. Financial Instruments with Off-Balance Sheet Risk The Company is a party to financial instruments with off-balance sheet risk. Such financial instruments consist of commitments to extend financing and standby letters of credit. If the commitments are exercised by the prospective borrowers, these financial instruments will become interest earning assets of the Company. If the commitments expire, the Company retains any fees paid by the prospective borrower. The fair value of commitments is estimated based upon fees currently charged to enter into similar agreements, taking into consideration the remaining terms of the agreements and the present creditworthiness of the borrower. For fixed rate commitments, the fair value estimation takes into consideration an interest rate risk factor. The fair value of these off-balance sheet items approximates the recorded amounts of the related fees, which are considered to be immaterial. The Company does not engage in activities involving interest rate swaps, forward placement contracts, or any other instruments commonly referred to as derivatives.

New Accounting Pronouncements [Abstract]
New Accounting Pronouncements	(9) New Accounting Pronouncements In January 2016, the FASB amended existing guidance to improve accounting standards for financial instruments including clarification and simplification of accounting and disclosure requirements and the requirement for public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes. These amendments are effective for public business entities for annual periods and interim periods within those annual periods beginning after December 15, 2017. The Company is evaluating the impact of these amendments on its consolidated financial statements. In February 2016, the FASB amended existing guidance to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. These amendments are effective for public business entities for annual periods and interim periods within those annual periods beginning after December 15, 2018. The Company is evaluating the impact of these amendments on its consolidated financial statements. In March 2016, the FASB amended existing guidance to simplify aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. These amendments are effective for public business entities for annual periods and interim periods within those annual periods beginning after December 15, 2016. The Company is evaluating the impact of these amendments on its consolidated financial statements. In June 2016, the FASB released Accounting Standards Update 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 Company is evaluating the impact of these amendments on its consolidated financial statements.
