There were no sales or transfers of held to maturity securities during the three months ended March 31, 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 generally 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 March 31, 2016, the Company’s security portfolio included certain securities which were in an unrealized loss position. These securities are U.S. Government Agencies or issuances from U.S. Government sponsored entities. 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 March 31, 2016.

Of the $23.4 million in real estate construction loans at March 31, 2016, approximately $13.6 million are secured by first mortgages to residential borrowers while approximately $9.8 million were to commercial borrowers for residential construction projects. Of the $26.6 million in real estate construction loans at December 31, 2015, approximately $16.0 million are secured by first mortgages to residential borrowers while approximately $10.6 million were to commercial borrowers for residential construction projects. The vast majority of construction loans are in the Company’s New York market. TrustCo lends in the geographic territory of its branch locations in New York, Florida, Massachusetts, New Jersey and Vermont. Although the loan portfolio is diversified, a portion of its debtors’ ability to repay depends significantly on the economic conditions prevailing in the respective geographic territory. The following table presents the recorded investment in non-accrual loans by loan class: March 31, 2016 (dollars in thousands) New York and Florida Total Loans in non-accrual status: Commercial: Commercial real estate $ 2,762 - 2,762 Real estate mortgage - 1 to 4 family: First mortgages 21,781 1,503 23,284 Home equity loans 139 - 139 Home equity lines of credit 3,749 299 4,048 Installment 74 - 74 Total non-accrual loans 28,505 1,802 30,307 Restructured real estate mortgages - 1 to 4 family 47 - 47 Total nonperforming loans $ 28,552 1,802 30,354 December 31, 2015 (dollars in thousands) New York and Florida Total Loans in non-accrual status: Commercial: Commercial real estate $ 3,024 - 3,024 Other - - - Real estate mortgage - 1 to 4 family: First mortgages 19,488 1,488 20,976 Home equity loans 212 - 212 Home equity lines of credit 3,573 329 3,902 Installment 90 8 98 Total non-accrual loans 26,387 1,825 28,212 Restructured real estate mortgages - 1 to 4 family 48 - 48 Total nonperforming loans $ 26,435 1,825 28,260 The Company transfers loans to other real estate owned, at fair value less cost to sell, in the period the Company obtains physical possession of the property (through legal title or through a deed in lieu). As of March 31, 2016 and December 31, 2015, other real estate owned included $4.9 million and $5.4 million, respectively, of residential foreclosed properties. In addition, non-accrual residential mortgage loans that are in the process of foreclosure had a recorded investment of $14.9 million and $13.2 million as of March 31, 2016 and December 31, 2015, respectively.

As a result, non-accrual loans include all loans 90 days or more past due as well as certain loans less than 90 days past due that were placed on non-accrual status for reasons other than delinquent status. There are no commitments to extend further credit on non-accrual or restructured loans. Activity in the allowance for loan losses by portfolio segment is summarized as follows: (dollars in thousands) For the three months ended March 31, 2016 Commercial Real Estate Mortgage- 1 to 4 Family Installment Total Balance at beginning of period $ 4,491 39,753 518 44,762 Loans charged off: New York and other states* 264 889 81 1,234 Florida - 84 16 100 Total loan chargeoffs 264 973 97 1,334 Recoveries of loans previously charged off: New York and other states* 40 118 11 169 Florida - 1 - 1 Total recoveries 40 119 11 170 Net loans charged off 224 854 86 1,164 Provision for loan losses 652 118 30 800 Balance at end of period $ 4,919 39,017 462 44,398 (dollars in thousands) For the three months ended March 31, 2015 Commercial Real Estate Mortgage- 1 to 4 Family Installment Total Balance at beginning of period $ 4,071 42,088 168 46,327 Loans charged off: New York and other states* 50 1,114 43 1,207 Florida - 109 - 109 Total loan chargeoffs 50 1,223 43 1,316 Recoveries of loans previously charged off: New York and other states* 16 110 6 132 Florida 1 - - 1 Total recoveries 17 110 6 133 Net loans charged off 33 1,113 37 1,183 Provision (credit) for loan losses (14 ) 554 260 800 Balance at end of period $ 4,024 41,529 391 45,944 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. The following tables present the balance in the allowance for loan losses and the recorded investment in loans by portfolio segment and based on impairment method as of March 31, 2016 and December 31, 2015: March 31, 2016 (dollars in thousands) Commercial Loans 1-to-4 Family Residential Real Estate Installment Loans Total Allowance for loan losses: Ending allowance balance attributable to loans: Individually evaluated for impairment $ - - - - Collectively evaluated for impairment 4,919 39,017 462 44,398 Total ending allowance balance $ 4,919 39,017 462 44,398 Loans: Individually evaluated for impairment $ 3,040 22,647 - 25,687 Collectively evaluated for impairment 195,725 3,071,300 8,667 3,275,692 Total ending loans balance $ 198,765 3,093,947 8,667 3,301,379 December 31, 2015 (dollars in thousands) Commercial Loans 1-to-4 Family Residential Real Estate Installment Loans Total Allowance for loan losses: Ending allowance balance attributable to loans: Individually evaluated for impairment $ - - - - Collectively evaluated for impairment 4,491 39,753 518 44,762 Total ending allowance balance $ 4,491 39,753 518 44,762 Loans: Individually evaluated for impairment $ 3,306 22,575 - 25,881 Collectively evaluated for impairment 200,109 3,057,923 9,391 3,267,423 Total ending loans balance $ 203,415 3,080,498 9,391 3,293,304 A loan for which the terms have been modified, and for which the borrower is experiencing financial difficulties, is considered a TDR and is classified as impaired. TDR’s at March 31, 2016 and December 31, 2015 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.

Interest income recognized on impaired loans was not material during the three months ended March 31, 2016 and 2015. As of March 31, 2016 and December 31, 2015 impaired loans included approximately $10.0 million and $10.6 million of 1 to 4 family residential real estate loans in accruing status that were identified as TDR’s in accordance with regulatory guidance related to Chapter 7 bankruptcy loans. Management evaluates impairment on impaired loans on a quarterly basis. If, during this evaluation, impairment of the loan is identified, a chargeoff is taken at that time. As a result, as of March 31, 2016 and December 31, 2015, 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 3/31/2016 Three months ended 3/31/2015 New York and other states*: Pre-Modification Post-Modification Pre-Modification Post-Modification (dollars in thousands) Number of Contracts Outstanding Recorded Investment Outstanding Recorded Investment Number of Contracts Outstanding Recorded Investment Outstanding Recorded Investment Real estate mortgage - 1 to 4 family: First mortgages 12 $ 1,270 $ 1,270 11 $ 2,240 $ 2,240 Home equity loans - - - 1 10 10 Home equity lines of credit 4 103 103 1 50 50 Total 16 $ 1,373 $ 1,373 13 $ 2,300 $ 2,300 Florida: Pre-Modification Post-Modification Pre-Modification Post-Modification (dollars in thousands) Number of Contracts Outstanding Recorded Investment Outstanding Recorded Investment Number of Contracts Outstanding Recorded Investment Outstanding Recorded Investment Real estate mortgage - 1 to 4 family: First mortgages 2 $ 245 $ 245 1 $ 157 $ 157 Home equity lines of credit - - - 2 50 50 Total 2 $ 245 $ 245 3 $ 207 $ 207 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. The following table presents, by class, TDR’s that defaulted during the three months ended March 31, 2016 and 2015 which had been modified within the last twelve months: Three months ended 3/31/2016 Three months ended 3/31/2015 New York and other states*: (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 2 $ 101 - $ - Home equity lines of credit 1 48 - - Total 3 $ 149 - $ - 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 - $ - - $ - Home equity lines of credit - $ - 1 $ 50 Total - $ - 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 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 March 31, 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: March 31, 2016 New York and other states: (dollars in thousands) Pass Classified Total Commercial: Commercial real estate $ 145,254 14,532 159,786 Other 23,791 730 24,521 $ 169,045 15,262 184,307 Florida: (dollars in thousands) Pass Classified Total Commercial: Commercial real estate $ 14,372 - 14,372 Other 86 - 86 $ 14,458 - 14,458 Total: (dollars in thousands) Pass Classified Total Commercial: Commercial real estate $ 159,626 14,532 174,158 Other 23,877 730 24,607 $ 183,503 15,262 198,765 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 $2.8 million and $3.0 million at March 31, 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 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 March 31, 2016 and December 31, 2015 is included in the aging of the recorded investment of past due loans table. In addition, the total nonperforming portion of these homogeneous loan pools as of March 31, 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.

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 Accounting Standards Update (“ASU”) 2014-09, “Revenue from Contracts with Customers (Topic 606)” implements a common revenue standard that clarifies the principles for recognizing revenue. The core principle of ASU 2014-09 is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. To achieve that core principle, an entity should apply the following steps: (i) identify the contract(s) with a customer, (ii) identify the performance obligations in the contract, (iii) determine the transaction price, (iv) allocate the transaction price to the performance obligations in the contract and (v) recognize revenue when (or as) the entity satisfies a performance obligation. In July 2015, FASB deferred the effective date of the ASU by one year which means ASU 2014-09 will be effective for the Company on January 1, 2018. In March 2016, FASB issued ASU 2016-08 which amended illustrative examples to clarify how to apply the implementation guidance on principal versus agent considerations. The Company is currently evaluating the potential impact of ASU 2014-09, and subsequent amendments, on its consolidated financial statements. 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.
