Financial Statement Presentation	(1) Financial Statement Presentation
	The unaudited Consolidated Interim Financial Statements of TrustCo Bank Corp NY (the “Company” or “TrustCo”) include the accounts of the subsidiaries after elimination of all significant intercompany accounts and transactions.  Prior period amounts are reclassified when necessary to conform to the current period presentation.  The net income reported for the three months ended March 31, 2015 is not necessarily indicative of the results that may be expected for the year ending December 31, 2015, or any interim periods.  These financial statements consider events that occurred through the date of filing.
	In the opinion of the management of the Company, the accompanying unaudited Consolidated Interim Financial Statements contain all recurring adjustments necessary to present fairly the financial position as of March 31, 2015, the results of operations and the cash flows for the three months ended March 31, 2015 and 2014.  The accompanying Consolidated Interim Financial Statements should be read in conjunction with the TrustCo Bank Corp NY year-end Consolidated Financial Statements, including notes thereto, which are included in TrustCo Bank Corp NY's 2014 Annual Report to Shareholders on Form 10-K.  The accompanying consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q and, therefore, do not include all information and notes necessary for a complete presentation of financial position, results of operations and cash flow activity required in accordance with accounting principles generally accepted in the United States.

Earnings Per Share [Abstract]
Earnings Per Share	(2) Earnings Per Share
	The Company computes earnings per share in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 260, Earnings Per Share (“ASC 260”). TrustCo adopted FASB ASC 260-10 (“ASC 260-10”), Determining Whether Instruments Granted in Share-Based Payment Transactions Are Participating Securities, which clarified that unvested share-based payment awards that contain nonforfeitable rights to receive dividends or divided equivalents (whether paid or unpaid) are participating securities, and thus, should be included in the two-class method of computing earnings per share (“EPS”).
	Participating securities under this statement include the unvested employees’ and directors’ restricted stock awards with time-based vesting, which receive nonforfeitable dividend payments.  These awards were settled in 2014 and as of March 31, 2015, the Company no longer has unvested restricted stock awards that were previously considered participating securities.
	A reconciliation of the component parts of earnings per share for the three months ended March 31, 2015 and 2014 is as follows:
	(dollars in thousands, except per share data)
		2015		2014
	For the three months ended
	March 31:
	Net income	$	10,715		11,011
	Less: Net income allocated to participating securities		-		12
	Net income allocated to common shareholders	$	10,715		10,999
	Basic EPS:
	Distributed earnings allocated to common stock	$	6,228		6,206
	Undistributed earnings allocated to common stock		4,487		4,793
	Net income allocated to common shareholders	$	10,715		10,999
	Weighted average common shares outstanding including participating securities		94,947		94,558
	Less: Participating securities		-		106
	Weighted average common shares		94,947		94,452
	Basic EPS	$	0.113		0.116
	Diluted EPS:
	Net income allocated to common shareholders	$	10,715		10,999
	Weighted average common shares for basic EPS		94,947		94,452
	Effect of Dilutive Securities:
	Stock Options		127		129
	Weighted average common shares including potential dilutive shares		95,074		94,581
	Diluted EPS	$	0.113		0.116
	For the three months ended March 31, 2015 and 2014, the weighted average number of antidilutive stock options excluded from diluted earnings per share was approximately 1.4 million and 2.4 million, respectively.  The stock options are antidilutive because the strike price is greater than the average fair value of the Company’s common stock for the periods presented.

Due in five years through ten years		-		-
	$	67,260		71,675
Actual maturities may differ from the above because of securities prepayments and the right of certain issuers to call or prepay their obligations without penalty.
There were no held to maturity securities in an unrecognized loss position as of March 31, 2015 or December 31, 2014.
There were no sales or transfers of held to maturity securities during the three months ended March 31, 2015 and 2014.
(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 an 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, 2015, the Company’s security portfolio included certain securities which were in an unrealized loss position, and are discussed below.
U.S. government sponsored enterprises
In the case of unrealized losses on U.S. government sponsored enterprises, because the decline in fair value is 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, 2015.
Mortgage backed securities and collateralized mortgage obligations - residential
All of the mortgage backed securities and collateralized mortgage obligations held by the Company were issued by U.S. government sponsored entities and agencies, primarily Ginnie Mae, Fannie Mae and Freddie Mac, which are institutions the government has affirmed its commitment to support. Because the decline in fair value is 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, 2015.
Small Business Administration (SBA) - guaranteed participation securities
All of the SBA securities held by the Company were issued and guaranteed by U.S. Small Business Administration. Because the decline in fair value is 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, 2015.
Mortgage backed securities and collateralized mortgage obligations – commercial
All of the mortgage backed securities and collateralized mortgage obligations held by the Company were issued by U.S. government-sponsored entities and agencies, are current as to the payment of interest and principal and the Company expects to collect the full amount of the principal and interest payments. Because the decline in fair value is 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, 2015.
As a result of the above analysis, during the three months ended March 31, 2015, the Company did not recognize any other-than-temporary impairment losses for credit or any other reason.

Of the $38.5 million in real estate construction loans at December 31, 2014, approximately $17.6 million are secured by first mortgages to residential borrowers while approximately $20.9 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.

At March 31, 2015 and December 31, 2014, there were no loans that are 90 days past due and still accruing interest. As a result, non-accrual loans includes all loans 90 days past due and greater 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.

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 in a TDR.
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, 2015 and December 31, 2014 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 months ended March 31, 2015 and 2014.
As of March 31, 2015 and December 31, 2014 impaired loans included approximately $10.4 million and $9.9 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 charge off is taken at that time. As a result, as of March 31, 2015 and December 31, 2014, 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:

The addition of these TDR’s did not have a significant impact on the allowance for loan losses.
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 ended March 31, 2015 and 2014 which had been modified within the last twelve months:
		Three months ended 3/31/2015					Three months ended 3/31/2014

The TDR’s that subsequently defaulted described above did not have a material impact on the allowance for loan losses as the underlying collateral was evaluated at the time these loans were identified as TDR’s, and a charge off was taken at that time, if necessary. Collateral values on these loans, as well as all non-accrual loans, are reviewed for collateral sufficiency on a quarterly basis.
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 over $150 thousand, such as commercial and commercial real estate loans, individually by grading the loans based on credit risk. In addition, the Company’s internal loan review department reviews non-homogeneous loans over $250 thousand by testing the loan grades assigned through the Company’s grading process.
The Company uses the following definitions for classified loans:
Special Mention: Loans classified as special mention have a potential weakness that deserves management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or of the Company’s credit position at some future date.
Substandard: Loans classified as substandard are inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. Loans classified as such have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected.
Doubtful: Loans classified as doubtful have all the weaknesses inherent in those loans classified as substandard, with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable. All doubtful loans are considered impaired.
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, 2015 and December 31, 2014, and based on the most recent analysis performed, the risk category of loans by class of loans is as follows:

Included in classified loans in the above tables are impaired loans of $2.8 million and $4.1 million at March 31, 2015 and December 31, 2014, 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 at March 31, 2015 and December 31, 2014 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 at March 31, 2015 and December 31, 2014 is presented in the recorded investment in non-accrual loans table.

Fair Value of Financial Instruments	3 Months Ended

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: The fair value of securities available for sale is 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 is included in the Consolidated Statements of Income in the respective investment class under total interest and dividend income. Also classified as available for sale securities, the fair value of equity securities is determined by quoted market prices and these are designated as Level 1. The Company does not have any securities that would be designated as level 3.
	Other Real Estate Owned: Assets acquired through loan foreclosure are initially recorded at fair value less costs to sell when acquired, establishing a new cost basis. These assets are subsequently accounted for at lower of cost or fair value less estimated costs to sell. Fair value is commonly based on recent real estate appraisals. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach. Adjustments are routinely made in the appraisal process to adjust for differences between the comparable sales and income data available. This results in a Level 3 classification of the inputs for determining fair value.
	Impaired Loans: At the time a loan is considered impaired, it is valued at the lower of cost or fair value. Impaired loans carried at fair value generally have had a chargeoff through the allowance for loan losses. For collateral dependent loans, fair value is commonly based on recent real estate appraisals. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach. Adjustments are routinely made in the appraisal process to adjust for differences between the comparable sales and income data available. Such adjustments may be significant and typically result in a Level 3 classification of the inputs for determining fair value. When obtained, non-real estate collateral may be valued using an appraisal, net book value per the borrower’s financial statements, or aging reports, adjusted or discounted based on management’s historical knowledge, changes in market conditions from the time of the valuation, and management’s expertise and knowledge of the client and client’s business, resulting in a Level 3 fair value classification. Impaired loans are evaluated on a quarterly basis for additional impairment and adjusted accordingly.
	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.

Other real estate owned, which is carried at fair value less costs to sell, approximated $7.0 million at March 31, 2015 and consisted of $3.4 million of commercial real estate and $3.6 million of residential real estate properties. A valuation charge of $259 thousand is included in earnings for the three months ended March 31, 2015.
Of the total impaired loans of $25.7 million at March 31, 2015, $1.8 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 March 31, 2015. Gross charge offs related to commercial impaired loans included in the table above were $50 thousand for the three months ended March 31, 2015, while gross charge offs related to residential impaired loans included in the table above amounted to $184 thousand.
Other real estate owned, which is carried at fair value less costs to sell, approximates $6.4 million at December 31, 2014 and consisted of $2.2 million of commercial real estate and $4.2 million of residential real estate properties. A valuation charge of $2.0 million is included in earnings for the year ended December 31, 2014.
Of the total impaired loans of $26.5 million at December 31, 2014, $3.6 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, 2014. Gross charge offs related to commercial impaired loans included in the table above were $17 thousand for the year ended December 31, 2014, while gross charge offs related to residential impaired loans included in the table above amounted to $349 thousand.

The specific estimation methods and assumptions used can have a substantial impact on the resulting fair values of financial instruments. 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	(8) New Accounting Pronouncements
	In January 2014, the FASB amended existing guidance to clarify when a creditor should be considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan such that the loan should be derecognized and the real estate recognized. These amendments clarify that an in substance repossession or foreclosure occurs, and a creditor is considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan, upon either: (1) the creditor obtaining legal title to the residential real estate property upon completion of a foreclosure, or (2) the borrower conveying all interest in the residential real estate property to the creditor to satisfy that loan through completion of a deed in lieu of foreclosure or through a similar legal agreement. Additional disclosures are required. These amendments are effective for public business entities for annual periods and interim periods within those annual periods beginning after December 15, 2014. The adoption of this standard did not have a material effect on the Company’s operating results or financial condition.
	In May 2014 the FASB amended existing guidance related to revenue from contracts with customers. This amendment supersedes and replaces nearly all existing revenue recognition guidance, including industry-specific guidance, establishes a new control-based revenue recognition model, changes the basis for deciding when revenue is recognized over time or at a point in time, provides new and more detailed guidance on specific topics and expands and improves disclosures about revenue. In addition, this amendment specifies the accounting for some costs to obtain or fulfill a contract with a customer. In April 2015, The FASB proposed to defer the effective date for one year. Early application is not permitted. The amendments should be applied retrospectively to all periods presented or retrospectively with the cumulative effect recognized at the date of initial application. The Company is currently evaluating the impact of this new accounting standard on the consolidated financial statements.
