Accounting Policies [Abstract]
Significant Accounting Policies [Text Block]	ACCOUNTING POLICIES In the opinion of the management of Arrow Financial Corporation (Arrow), the accompanying unaudited consolidated interim financial statements contain all of the adjustments necessary to present fairly the financial position as of June 30, 2016 , December 31, 2015 and June 30, 2015 ; the results of operations for the three-month period ended June 30, 2016 ; the consolidated statements of comprehensive income for the three- and six-month periods ended June 30, 2016 ; the changes in stockholders' equity for the six -month periods ended June 30, 2016 and 2015 ; and the cash flows for the six -month periods ended June 30, 2016 and 2015 . All such adjustments are of a normal recurring nature. Certain prior period amounts have been reclassified to conform to the current presentation. The preparation of financial statements requires the use of management estimates. The unaudited consolidated interim financial statements should be read in conjunction with the audited annual consolidated financial statements of Arrow for the year ended December 31, 2015 , included in Arrow's 2015 Form 10-K. New Accounting Standards Updates (ASU): During 2016, through the date of this report, the FASB issued 13 accounting standards updates. Some of the standards listed below did not have had an immediate impact on Arrow, but could in the future. ASU 2016-01 "Recognition and Measurement of Financial Assets and Financial Liabilities" will significantly change the income statement impact of equity investments. For Arrow, the standard is effective for the first quarter of 2018, and will require that equity investments be measured at fair value, with changes in fair value measured in net income. Currently, we hold a small portfolio of equity investments and we do not expect that the adoption of this change in accounting for equity investments will have a material impact on our financial position or the results of operations in periods subsequent to its adoption. ASU 2016-02 "Leases" will require the recognition of operating leases. For Arrow, the standard becomes effective in the first quarter of 2019. We do not expect that the adoption of this change in accounting for operating leases will have a material impact on our financial position or the results of operations in periods subsequent to its adoption. ASU 2016-09 "Compensation - Stock Compensation" simplifies certain aspects of accounting for share-based payment transactions, including the tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. For Arrow, the standard becomes effective in the first quarter of 2017. We do not expect that the adoption of this change in accounting for stock-based compensation will have a material impact on our financial position or the results of operations in periods subsequent to its adoption. ASU 2016-13 "Financial Instruments - Credit Losses" will change the way we and other financial entities recognize losses on assets measured at amortized costs and change the method for recognizing credit losses on securities available-for-sale. Currently loan losses are recognized using an "incurred loss" methodology. Under ASU 2016-13, the methodology will change to a current expected loss over the life of the loan. Currently, credit losses on available-for-sale securities reduce the carrying value of the instrument and cannot be reversed. Under ASU 2016-13, the amount of the credit loss is carried as a valuation allowance and can be reversed. For Arrow, the standard is effective for the first quarter of 2020 and early adoption is allowed in 2019. The Company is currently evaluating the impact of the pending adoption of the ASU on its consolidated financial statements. The initial adjustment will not be reported in earnings, but as the cumulative effect of a change in accounting principle.

residential are included based on their expected average lives. Actual maturities will differ from the table above because issuers may have the right to call or prepay obligations with, or without, prepayment penalties. In the available-for-sale category at June 30, 2016 , U.S. agency obligations consisted solely of U.S. Government Agency securities with an amortized cost of $ 155.9 million and a fair value of $ 158.0 million . Mortgage-backed securities - residential consisted of U.S. Government Agency securities with an amortized cost of $10.3 million and a fair value of $10.4 million and government sponsored entity (GSE) securities with an amortized cost of $147.6 million and a fair value of $151.3 million . In the held-to-maturity category at June 30, 2016 , mortgage-backed securities-residential consisted of U.S Government Agency securities with an amortized cost of $ 3.5 million and a fair value of $ 3.6 million and GSE securities with an amortized cost of $ 81.3 million and a fair value of $ 84.2 million . In the available-for-sale category at December 31, 2015 , U.S. agency obligations consisted solely of U.S. Government Agency securities with an amortized cost of $ 155.9 million and a fair value of $ 155.8 million . Mortgage-backed securities - residential consisted of U.S. Government Agency securities with an amortized cost of $ 15.7 million and a fair value of $ 15.8 million and GSE securities with an amortized cost of $ 161.7 million and a fair value of $ 162.7 million . In the held-to-maturity category at December 31, 2015 , mortgage-backed securities-residential consisted of U.S. Government Agency securities with an amortized cost of $ 3.8 million and a fair value of $ 3.9 million and GSE securities with an amortized cost of $ 89.8 million and a fair value of $ 90.5 million . In the available-for-sale category at June 30, 2015 , U.S. agency obligations consisted solely of U.S. Government Agency securities with an amortized cost of $ 156.2 million and a fair value of $ 156.9 million . Mortgage-backed securities - residential consisted of US Government Agency securities with an amortized cost of $ 30.8 million and a fair value of $ 31.7 million and GSE securities with an amortized cost of $ 123.7 million and a fair value of $ 126.0 million . In the held-to-maturity category at June 30, 2015 , mortgage-backed securities-residential consisted of U.S. Government Agency securities with an amortized cost of $ 28.8 million and a fair value of $ 29.0 million and GSE securities with an amortized cost of $ 74.5 million and a fair value of $ 75.4 million . Securities in a continuous loss position, in the tables above for June 30, 2016 , December 31, 2015 and June 30, 2015 , do not reflect any deterioration of the credit worthiness of the issuing entities. U.S. Agency issues, including agency-backed collateralized mortgage obligations and mortgage-backed securities, are all rated at least Aaa by Moody's or AA+ by Standard and Poor's. The state and municipal obligations are general obligations supported by the general taxing authority of the issuer, and in some cases are insured. Obligations issued by school districts are supported by state aid. For any non-rated municipal securities, credit analysis is performed in-house based upon data that has been submitted by the issuers to the NY State Comptroller. That analysis reflects satisfactory credit worthiness of the municipalities. Corporate and other debt securities continue to be rated above investment grade according to Moody's and Standard and Poor's. Subsequent to June 30, 2016 , and through the date of filing this report, there were no securities downgraded below investment grade. The unrealized losses on these temporarily impaired securities are primarily the result of changes in interest rates for fixed rate securities where the interest rate received is less than the current rate available for new offerings of similar securities, changes in market spreads as a result of shifts in supply and demand, and/or changes in the level of prepayments for mortgage related securities. Because we do not currently intend to sell any of our temporarily impaired securities, and because it is not more likely-than-not that we would be required to sell the securities prior to recovery, the impairment is considered temporary.

Financing Receivables [Text Block]	LOANS (In Thousands) Loan Categories and Past Due Loans The following table presents loan balances outstanding as of June 30, 2016 , December 31, 2015 and June 30, 2015 and an analysis of the recorded investment in loans that are past due at these dates. Generally, Arrow considers an amortizing loan past due 30 or more days when the borrower is two payments past due. Loans held-for-sale of $2,440 , $298 and $3,656 as of June 30, 2016 , December 31, 2015 and June 30, 2015 , respectively, are included in the residential real estate balances for current loans.

Such loans are made available to businesses for working capital needs such as inventory and receivables, business expansion and equipment purchases. Generally, a collateral lien is placed on equipment or other assets owned by the borrower. These loans carry a higher risk than commercial real estate loans due to the nature of the underlying collateral, which can be business assets such as equipment and accounts receivable and generally have a lower liquidation value than real estate. In the event of default by the borrower, the Company may be required to liquidate collateral at deeply discounted values. To reduce the risk, management usually obtains personal guarantees of the borrowers. Commercial Real Estate - The Company offers commercial real estate loans to finance real estate purchases, refinancings, expansions and improvements to commercial properties. Commercial real estate loans are made to finance the purchases of real property which generally consists of real estate with completed structures. These commercial real estate loans are secured by first liens on the real estate, which may include apartments, commercial structures, housing businesses, healthcare facilities, and both owner- and non owner-occupied facilities. These loans are typically less risky than commercial loans, since they are secured by real estate and buildings, and are generally originated in amounts of no more than 80% of the appraised value of the property. However, the Company also offers commercial construction and land development loans to finance projects, primarily within the communities that we serve. Many projects will ultimately be used by the borrowers' businesses, while others are developed for resale. These real estate loans are also secured by first liens on the real estate, which may include apartments, commercial structures, housing business, healthcare facilities and both owner-occupied and non-owner-occupied facilities. There is enhanced risk during the construction period, since the loan is secured by an incomplete project. Consumer Loans - The Company offers a variety of consumer installment loans to finance personal expenditures. Most of these loans carry a fixed rate of interest with principal repayment terms typically ranging from one to five years, based upon the nature of the collateral and the size of the loan. In addition to installment loans, the Company also offers personal lines of credit and overdraft protection. Several loans are unsecured, which carry a higher risk of loss. Also included in this category are automobile loans. The Company primarily finances the purchases of automobiles indirectly through dealer relationships located throughout upstate New York and Vermont. Most of these loans carry a fixed rate of interest with principal repayment terms typically ranging from three to seven years. Indirect consumer loans are underwritten on a secured basis using the underlying collateral being financed. Residential Real Estate Mortgages - Residential real estate loans consist primarily of loans secured by first or second mortgages on primary residences. We originate adjustable-rate and fixed-rate one-to-four-family residential real estate loans for the construction, purchase or refinancing of an existing mortgage. These loans are collateralized primarily by owner-occupied properties generally located in the Company’s market area. Loans on one-to-four-family residential real estate are generally originated in amounts of no more than 85% of the purchase price or appraised value (whichever is lower), or have private mortgage insurance. The Company’s underwriting analysis for residential mortgage loans typically includes credit verification, independent appraisals, and a review of the borrower’s financial condition. Mortgage title insurance and hazard insurance are normally required. It is our general practice to underwrite our residential real estate loans to secondary market standards. Construction loans have a unique risk, because they are secured by an incomplete dwelling. This risk is reduced through periodic site inspections, including one at each loan draw period. In addition, the Company offers fixed home equity loans as well as home equity lines of credit to consumers to finance home improvements, debt consolidation, education and other uses. Our policy allows for a maximum loan to value ratio of 80%, although periodically higher advances are allowed. The Company originates home equity lines of credit and second mortgage loans (loans secured by a second junior lien position on one-to-four-family residential real estate). Risk is generally reduced through underwriting criteria, which include credit verification, appraisals, a review of the borrower's financial condition, and personal cash flows. A security interest, with title insurance when necessary, is taken in the underlying real estate.

Additions are made to the allowance for loan losses through a periodic provision for loan losses. Actual loan losses are charged against the allowance for loan losses when loans are deemed uncollectible and recoveries of amounts previously charged off are recorded as credits to the allowance for loan losses. Our loan officers and risk managers meet at least quarterly to discuss and review the conditions and risks associated with certain criticized and classified commercial-related relationships. In addition, our independent internal loan review department performs periodic reviews of the risk ratings on individual loans in our commercial loan portfolio. We use a two-step process to determine the provision for loan losses and the amount of the allowance for loan losses. We measure impairment on our impaired loans on a quarterly basis. Our impaired loans are generally nonaccrual loans over $250 thousand and all troubled debt restructured loans. Our impaired loans are generally considered to be collateral dependent with the specific reserve, if any, determined based on the value of the collateral less estimated costs to sell. The remainder of the portfolio is evaluated on a pooled basis. For each homogeneous loan pool, we estimate a total loss factor based on the historical net loss rates adjusted for applicable qualitative factors. We update the total loss factors assigned to each loan category on a quarterly basis. For the commercial and commercial real estate categories, we further segregate the loan categories by credit risk profile (pools of loans graded satisfactory, special mention and substandard). Additional description of the credit risk classifications is detailed in the Credit Quality Indicators section of this note. We determine the annualized historical net loss rate for each loan category using a trailing three-year net charge-off average. While historical net loss experience provides a reasonable starting point for our analysis, historical net losses, or even recent trends in net losses, do not by themselves form a sufficient basis to determine the appropriate level of the allowance for loan losses. Therefore, we also consider and adjust historical net loss factors for qualitative factors that impact the inherent risk of loss associated with our loan categories within our total loan portfolio. These include: • Changes in the volume and severity of past due, nonaccrual and adversely classified loans • Changes in the nature and volume of the portfolio and in the terms of loans • Changes in the value of the underlying collateral for collateral dependent loans • Changes in lending policies and procedures, including changes in underwriting standards and collection, charge-off, and recovery practices not considered elsewhere in estimating credit losses • Changes in the quality of the loan review system • Changes in the experience, ability, and depth of lending management and other relevant staff • Changes in international, national, regional, and local economic and business conditions and developments that affect the collectibility of the portfolio • The existence and effect of any concentrations of credit, and changes in the level of such concentrations • The effect of other external factors such as competition and legal and regulatory requirements on the level of estimated credit losses in the existing portfolio or pool Further, due to the imprecise nature of the loan loss estimation process, the risk attributes of our loan portfolio may not be fully captured in data related to the determination of loss factors used to determine our analysis of the adequacy of the allowance for loan losses. Management, therefore, has established an unallocated portion within the allowance for loan losses reflecting the imprecision that naturally exists in the allowance for loan loss estimation process. The unallocated allowance for loan losses is not considered a significant component of the overall allowance for loan loss estimation process and has been declining steady over the past few quarters.

Borrowers have satisfactory repayment histories and primary and secondary sources of repayment can be clearly identified; 2) Special Mention - Loans in this category have potential weaknesses that deserve management ’ s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the asset or in the institution ’ s credit position at some future date. "Special mention" assets are not adversely classified and do not expose an institution to sufficient risk to warrant adverse classification. Loans which might be assigned this risk rating include loans to borrowers with deteriorating financial strength and/or earnings record and loans with potential for problems due to weakening economic or market conditions; 3) Substandard - Loans classified as “ substandard ” are inadequately protected by the current sound net worth or paying capacity of the borrower or the collateral pledged, if any. Loans in this category have well defined weaknesses that jeopardize the repayment. They are characterized by the distinct possibility that the bank will sustain some loss if the deficiencies are not corrected. “ Substandard ” loans may include loans which are likely to require liquidation of collateral to effect repayment, and other loans where character or ability to repay has become suspect. Loss potential, while existing in the aggregate amount of substandard assets, does not have to exist in individual assets classified substandard; 4) Doubtful - Loans classified as “ doubtful ” have all of the weaknesses inherent in those classified as “ substandard ” with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of current existing facts, conditions, and values highly questionable and improbable. Although possibility of loss is extremely high, classification of these loans as “ loss ” has been deferred due to specific pending factors or events which may strengthen the value (i.e. possibility of additional collateral, injection of capital, collateral liquidation, debt restructure, economic recovery, etc). Loans classified as “ doubtful ” need to be placed on non-accrual; and 5) Loss - Loans classified as “ loss ” are considered uncollectible and of such little value that their continuance as bankable assets is not warranted. As of the date of the balance sheet, all loans in this category have been charged-off to the allowance for loan losses. Large commercial loans are evaluated on an annual basis, unless the credit quality indicator falls to a level of "special mention" or below, when the loan is evaluated quarterly. The credit quality indicator is one of the factors used to determine any loss, as further described in this footnote. For the purposes of the table above, nonperforming consumer loans are those loans on nonaccrual status or are 90 days or more past due and still accruing interest. Impaired Loans The following table presents information on impaired loans based on whether the impaired loan has a recorded related allowance or has no recorded related allowance: Impaired Loans Commercial Commercial Real Estate Consumer Residential Total June 30, 2016 Recorded Investment: With No Related Allowance $ — $ 1,850 $ 93 $ 640 $ 2,583 With a Related Allowance — 1,692 — — 1,692 Unpaid Principal Balance: With No Related Allowance — 1,850 93 640 2,583 With a Related Allowance — 1,692 — — 1,692 December 31, 2015 Recorded Investment: With No Related Allowance $ 155 $ 2,372 $ 114 $ 645 $ 3,286 With a Related Allowance — — — — — Unpaid Principal Balance: With No Related Allowance 155 2,372 144 645 3,316 With a Related Allowance — — — — — June 30, 2015 Recorded Investment: With No Related Allowance $ 462 $ 1,491 $ 93 $ 1,697 $ 3,743 With a Related Allowance — — — 594 594 Unpaid Principal Balance: With No Related Allowance 462 1,491 93 1,697 $ 3,743 With a Related Allowance — — — 594 594 For the Quarter Ended: June 30, 2016 Average Recorded Balance: With No Related Allowance $ — $ 2,111 $ 106 $ 641 $ 2,858 With a Related Allowance — $ 1,698 — $ — 1,698 Interest Income Recognized: With No Related Allowance — 2 1 — 3 With a Related Allowance — — — — — Cash Basis Income: With No Related Allowance — — — — — With a Related Allowance — — — — — June 30, 2015 Average Recorded Balance: With No Related Allowance $ 461 $ 1,492 $ 100 $ 1,697 $ 3,750 With a Related Allowance — — — 597 597 Interest Income Recognized: With No Related Allowance 2 — 1 — 3 With a Related Allowance — — — — — Cash Basis Income: With No Related Allowance — — — — — With a Related Allowance — — — — — Impaired Loans Commercial Commercial Real Estate Consumer Residential Total For the Year-To-Date Period Ended: June 30, 2016 Average Recorded Balance: With No Related Allowance $ 78 $ 2,111 $ 104 $ 643 $ 2,936 With a Related Allowance — 846 — — 846 Interest Income Recognized: With No Related Allowance — 11 2 — 13 With a Related Allowance — — — — — Cash Basis Income: With No Related Allowance — — — — — With a Related Allowance — — — — — June 30, 2015 Average Recorded Balance: With No Related Allowance $ 478 $ 1,492 $ 106 $ 1,688 $ 3,764 With a Related Allowance — — — 577 577 Interest Income Recognized: With No Related Allowance 4 — 2 1 7 With a Related Allowance — — — — — Cash Basis Income: With No Related Allowance — — — — — With a Related Allowance — — — — — At June 30, 2016 , December 31, 2015 and June 30, 2015 , all impaired loans were considered to be collateral dependent and were therefore evaluated for impairment based on the fair value of collateral less estimated cost to sell. Interest income recognized in the table above, represents income earned after the loans became impaired and includes restructured loans in compliance with their modified terms and nonaccrual loans where we have recognized interest income on a cash basis. Loans Modified in Trouble Debt Restructurings The following table presents information on loans modified in trouble debt restructurings during the periods indicated. All loans were modified under Arrow's own programs. The principal modification, for all the modifications in the table below, involved payment deferrals.

Guarantees [Text Block]	GUARANTEES (In Thousands) The following table presents the balance for standby letters of credit for the periods ended June 30, 2016 , December 31, 2015 and June 30, 2015 : Loan Commitments and Letters of Credit June 30, 2016 December 31, 2015 June 30, 2015 Notional Amount: Commitments to Extend Credit $ 292,839 $ 278,623 $ 290,666 Standby Letters of Credit 3,137 3,065 3,213 Fair Value: Commitments to Extend Credit $ — $ — $ — Standby Letters of Credit 24 2 24 Arrow is party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit and standby letters of credit. Commitments to extend credit include home equity lines of credit, commitments for residential and commercial construction loans and other personal and commercial lines of credit. These instruments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the consolidated balance sheets. The contract or notional amounts of those instruments reflect the extent of the involvement Arrow has in particular classes of financial instruments. Arrow's exposure to credit loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit and standby letters of credit is represented by the contractual notional amount of those instruments. Arrow uses the same credit policies in making commitments and conditional obligations as it does for on-balance sheet instruments. Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. Arrow evaluates each customer's creditworthiness on a case-by-case basis. Home equity lines of credit are secured by residential real estate. Construction commitments are secured by underlying real estate. For other lines of credit, the amount of collateral obtained, if deemed necessary by Arrow upon extension of credit, is based on management's credit evaluation of the counterparty. Collateral held varies, but may include accounts receivable, inventory, property, plant and equipment, and income-producing commercial properties. Most of the commitments are variable rate instruments. Arrow has issued conditional commitments in the form of standby letters of credit to guarantee payment on behalf of a customer and guarantee the performance of a customer to a third party. Standby letters of credit generally arise in connection with lending relationships. The credit risk involved in issuing these instruments is essentially the same as that involved in extending loans to customers. Contingent obligations under standby letters of credit at June 30, 2016 , December 31, 2015 and June 30, 2015 represent the maximum potential future payments Arrow could be required to make. Typically, these instruments have terms of 12 months or less and expire unused; therefore, the total amounts do not necessarily represent future cash requirements. Each customer is evaluated individually for creditworthiness under the same underwriting standards used for commitments to extend credit and on-balance sheet instruments. Company policies governing loan collateral apply to standby letters of credit at the time of credit extension. Loan-to-value ratios generally range from 50% for movable assets, such as inventory, to 100% for liquid assets, such as bank CD's. Fees for standby letters of credit typically range from 1% to 3% of the notional amount. Fees are collected upfront and are amortized over the life of the commitment. The fair values of Arrow's standby letters of credit at June 30, 2016 , December 31, 2015 and June 30, 2015 , in the table above, were the same as the carrying amounts. The fair value of standby letters of credit is based on the fees currently charged for similar agreements or the cost to terminate the arrangement with the counterparties. The fair value of commitments to extend credit is determined by estimating the fees to enter into similar agreements, taking into account the remaining terms and present creditworthiness of the counterparties, and for fixed rate loan commitments, the difference between the current and committed interest rates. Arrow provides several types of commercial lines of credit and standby letters of credit to its commercial customers. The pricing of these services is not isolated, as Arrow considers the customer's complete deposit and borrowing relationship in pricing individual products and services. The commitments to extend credit also include commitments under home equity lines of credit, for which Arrow charges no fee. The carrying value and fair value of commitments to extend credit are not material and Arrow does not expect to incur any material loss as a result of these commitments.

Fair Value Methodology for Assets and Liabilities Measured on a Recurring Basis The fair value of Level 1 securities available-for-sale are based on unadjusted, quoted market prices from exchanges in active markets. The fair value of Level 2 securities available-for-sale are based on an independent bond and equity pricing service for identical assets or significantly similar securities and an independent equity pricing service for equity securities not actively traded. 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. Fair Value Methodology for Assets and Liabilities Measured on a Nonrecurring Basis The fair value of collateral dependent impaired loans was based on third-party appraisals of the collateral. The fair value of other real estate owned was based on third-party appraisals. Other assets which might have been included in this table include mortgage servicing rights, goodwill and other intangible assets. Arrow evaluates each of these assets for impairment on a quarterly basis, with no impairment recognized for these assets at June 30, 2016 , December 31, 2015 and June 30, 2015 .

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. Fair values for loans are estimated for portfolios of loans with similar financial characteristics. Loans are segregated by type such as commercial, commercial real estate, residential mortgage, indirect and other consumer loans. Each loan category is further segmented into fixed and adjustable interest rate terms and by performing and nonperforming categories. The fair value of performing loans is calculated by discounting scheduled cash flows through the estimated maturity using estimated market discount rates that reflect the credit and interest rate risk inherent in the loan. The estimate of maturity is based on historical experience with repayments for each loan classification, modified, as required, by an estimate of the effect of current economic and lending conditions. Fair value for nonperforming loans is generally based on recent external appraisals. If appraisals are not available, estimated cash flows are discounted using a rate commensurate with the risk associated with the estimated cash flows. Assumptions regarding credit risk, cash flows and discount rates are judgmentally determined using available market information and specific borrower information. The fair value of time deposits is based on the discounted value of contractual cash flows, except that the fair value is limited to the extent that the customer could redeem the certificate after imposition of a premature withdrawal penalty. The discount rates are estimated using the FHLBNY yield curve, which is considered representative of Arrow ’ s time deposit rates. The fair value of all other deposits is equal to the carrying value. The fair value of FHLBNY advances is estimated based on the discounted value of contractual cash flows. The discount rate is estimated using current rates on FHLBNY advances with similar maturities and call features. Based on Arrow ’ s capital adequacy, the book value of the outstanding trust preferred securities (Junior Subordinated Obligations Issued to Unconsolidated Subsidiary Trusts) are considered to approximate fair value since the interest rates are variable (indexed to LIBOR) and Arrow is well-capitalized.

Accounting Policies [Abstract]
New Accounting Standards Updates [Policy Text Block]	New Accounting Standards Updates (ASU): During 2016, through the date of this report, the FASB issued 13 accounting standards updates. Some of the standards listed below did not have had an immediate impact on Arrow, but could in the future. ASU 2016-01 "Recognition and Measurement of Financial Assets and Financial Liabilities" will significantly change the income statement impact of equity investments. For Arrow, the standard is effective for the first quarter of 2018, and will require that equity investments be measured at fair value, with changes in fair value measured in net income. Currently, we hold a small portfolio of equity investments and we do not expect that the adoption of this change in accounting for equity investments will have a material impact on our financial position or the results of operations in periods subsequent to its adoption. ASU 2016-02 "Leases" will require the recognition of operating leases. For Arrow, the standard becomes effective in the first quarter of 2019. We do not expect that the adoption of this change in accounting for operating leases will have a material impact on our financial position or the results of operations in periods subsequent to its adoption. ASU 2016-09 "Compensation - Stock Compensation" simplifies certain aspects of accounting for share-based payment transactions, including the tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. For Arrow, the standard becomes effective in the first quarter of 2017. We do not expect that the adoption of this change in accounting for stock-based compensation will have a material impact on our financial position or the results of operations in periods subsequent to its adoption. ASU 2016-13 "Financial Instruments - Credit Losses" will change the way we and other financial entities recognize losses on assets measured at amortized costs and change the method for recognizing credit losses on securities available-for-sale. Currently loan losses are recognized using an "incurred loss" methodology. Under ASU 2016-13, the methodology will change to a current expected loss over the life of the loan. Currently, credit losses on available-for-sale securities reduce the carrying value of the instrument and cannot be reversed. Under ASU 2016-13, the amount of the credit loss is carried as a valuation allowance and can be reversed. For Arrow, the standard is effective for the first quarter of 2020 and early adoption is allowed in 2019. The Company is currently evaluating the impact of the pending adoption of the ASU on its consolidated financial statements. The initial adjustment will not be reported in earnings, but as the cumulative effect of a change in accounting principle.
