Risks and Uncertainties [Abstract]
Risks and Uncertainties	RISKS AND UNCERTAINTIES Nature of Operations - Arrow Financial Corporation, a New York corporation ("Arrow," the "Company," "we," or "us"), was incorporated on March 21, 1983 and is registered as a bank holding company within the meaning of the Bank Holding Company Act of 1956. The banking subsidiaries are Glens Falls National Bank and Trust Company ("GFNB") whose main office is located in Glens Falls, New York, and Saratoga National Bank and Trust Company ("SNB") whose main office is located in Saratoga Springs, New York. The two subsidiary banks provide a full range of services to individuals and small to mid-size businesses in northeastern New York State from Albany, the State's capitol, to the Canadian border. Both banks have wealth management departments which provide investment management and administrative services. An active subsidiary of GFNB is Upstate Agency LLC, offering insurance services including property and casualty insurance, group health insurance and individual life insurance products. North Country Investment Advisers, Inc., a registered investment adviser that provides investment advice to our proprietary mutual fund, and Arrow Properties, Inc., a real estate investment trust (REIT), are subsidiaries of GFNB. Arrow also owns directly two subsidiary business trusts, organized in 2003 and 2004 to issue trust preferred securities (TRUPs), which are still outstanding. Concentrations of Credit - With the exception of some indirect auto lending, Arrow's loans are primarily with borrowers in upstate New York. Although the loan portfolios of the subsidiary banks are well diversified, tourism has a substantial impact on the northeastern New York economy. The commitments to extend credit are fairly consistent with the distribution of loans presented in Note 5, " Loans, " generally have the same credit risk and are subject to normal credit policies. Generally, the loans are secured by assets and are expected to be repaid from cash flow or the sale of selected assets of the borrowers. Arrow evaluates each customer's creditworthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by Arrow upon extension of credit, is based upon management's credit evaluation of the counterparty. The nature of the collateral varies with the type of loan and may include: residential real estate, cash and securities, inventory, accounts receivable, property, plant and equipment, income producing commercial properties and automobiles. Liquidity - The objective of effective liquidity management is to ensure that Arrow has the ability to raise cash when needed at a reasonable cost. This includes the capability of meeting expected and unexpected obligations to Arrow's customers at any time. Given the uncertain nature of customer demands and the need to maximize earnings, Arrow must have available reasonably priced sources of funds, both on- and off-balance sheet, that can be accessed quickly in times of need. Arrow’s liquidity position should provide the Company with the necessary flexibility to address any unexpected near-term disruptions such as reduced cash flows from the investment and loan portfolio, unexpected deposit runoff, or increased loan originations. Arrow's primary sources of available liquidity are overnight investments in federal funds sold, interest bearing bank balances at the Federal Reserve Bank of New York ("FRBNY"), advances from the FRBNY Bank Term Funding Program ("BTFP") and cash flow from investment securities and loans.

Accounting Policies [Abstract]
Accounting Policies	ACCOUNTING POLICIES The accompanying unaudited interim consolidated financial statements contain all of the adjustments necessary to present fairly the financial position as of June 30, 2024, December 31, 2023 and June 30, 2023; the results of operations for the three and six month periods ended June 30, 2024 and 2023; the consolidated statements of comprehensive income for the three and six month periods ended June 30, 2024 and 2023; the changes in stockholders' equity for the three and six month periods ended June 30, 2024 and 2023; and the cash flows for the six month periods ended June 30, 2024 and 2023. All such adjustments are of a normal recurring nature. The unaudited interim consolidated financial statements should be read in conjunction with the audited annual consolidated financial statements of Arrow for the year ended December 31, 2023 included in Arrow's Annual Report on Form 10-K for the year ended December 31, 2023 (the "2023 Form 10-K"). Recently Issued Accounting Standards In March 2020, the FASB issued ASU 2020-04, "Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting." On January 7, 2021, the FASB issued ASU 2021-01, which refines the scope of ASC 848 and clarifies some of its guidance. The ASU and related amendments provide temporary optional expedients and exceptions to the existing guidance for applying GAAP to affected contract modifications and hedge accounting relationships in the transition away from the LIBOR or other interbank offered rate on financial reporting. The guidance also allows a one-time election to sell and/or reclassify to AFS or trading HTM debt securities that reference an interest rate affected by reference rate reform. The amendments in this ASU are effective March 12, 2020 through December 31, 2022 and permit relief solely for reference rate reform actions and different elections over the effective date for legacy and new activity. In December 2022, FASB issued ASU 2022-06, "Reference Rate Reform (Topic 848)" which deferred the sunset date of Topic 848 to December 31, 2024, to allow for a transition period after the sunset of LIBOR. Arrow does not expect ASU 2022-06 will have a material impact on its consolidated financial statements. In November 2023, the FASB issued ASU No. 2023-07, Segment Reporting: Improvements to Reportable Segment Disclosures. This ASU amends FASB Topic 280 to permit the disclosure of multiple measures of a segment's profit or loss, and requires an entity with a single reportable segment to apply FASB Topic 280 in its entirety. In addition, this ASU requires new segment disclosures. Arrow does not expect this new standard will have a material impact on the consolidated financial statements. In December 2023, the FASB issued ASU 2023-09,1 which establishes new income tax disclosure requirements in addition to modifying and eliminating certain existing requirements. Under the new guidance, entities must consistently categorize and provide greater disaggregation of information in the rate reconciliation. They must also further disaggregate income taxes paid. Arrow does not expect this new standard will have a material impact on the consolidated financial statements. Management’s Use of Estimates The preparation of the consolidated financial statements in conformity with accounting principles generally accepted in the United States of America (GAAP) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of income and expenses during the reporting period. Management utilized estimates and assumptions in its evaluation of potential impairment of Arrow's right-of-use lease assets, goodwill and intangible assets. Our most significant estimate is the allowance for credit losses. Other estimates include the fair value of financial instruments, evaluation of pension and other post-retirement liabilities, an analysis of a need for a valuation allowance for deferred tax assets and a reserve for unfunded loan commitments recorded as an other liability. Actual results could differ from those estimates. A material estimate that is particularly susceptible to significant change in the near term is the allowance for credit losses. In connection with the determination of the allowance for credit losses management obtains economic forecasts from reliable sources and appraisals for properties. The allowance for credit losses is management’s best estimate of the life of loan losses as of the balance sheet date. While management uses available information to recognize losses on loans, future adjustments to the allowance for credit losses may be necessary based on changes in economic conditions. Allowance for Credit Losses – Loans - Accounting Standards Update (ASU) 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (CECL) approach requires an estimate of the credit losses expected over the life of a loan (or pool of loans). It replaces the incurred loss approach’s threshold that required the recognition of a credit loss when it was probable that a loss event was incurred. The allowance for credit losses is a valuation account that is deducted from, or added to, the loans’ amortized cost basis to present the net lifetime amount expected to be collected on the loans. Credit losses are charged off against the allowance when management believes a loan balance is confirmed to be uncollectible. Expected recoveries do not exceed the aggregate of amounts previously charged off and expected to be charged off. Management estimates the allowance using relevant available information from internal and external sources related to past events, current conditions, and a reasonable and supportable single economic forecast. Historical credit loss experience provides the basis for the estimation of expected credit losses. Arrow's historical loss experience is supplemented with peer information when there is insufficient loss data for Arrow. Peer selection is based on a review of institutions with comparable loss experience as well as loan yield, bank size, portfolio concentration and geography. Adjustments to historical loss information are made for differences in current loan-specific risk characteristics such as differences in credit concentrations, delinquency level, collateral values and underwriting standards as well as changes in economic conditions or other relevant factors. Management judgment is required at each point in the measurement process. Portfolio segment is defined as the level at which an entity develops and documents a systematic methodology to determine its allowance for credit losses. Management developed portfolio segments for estimating loss based on type of borrower and collateral as follows: Commercial Loans Commercial Real Estate Loans Consumer Loans Residential Loans Further details related to loan portfolio segments is included in Note 5 Loans. Historical credit loss experience for both Arrow and segment-specific peers provides the basis for the estimation of expected credit losses. Arrow utilized regression analyses of peer data where observed credit losses and selected economic factors were utilized to determine suitable loss drivers for modeling lifetime probability of default (PD) rates. Arrow uses the discounted cash flow (DCF) method to estimate expected credit losses for the commercial, commercial real estate, and residential segments. For each of these loan segments, Arrow generates cash flow projections at the instrument level wherein payment expectations are adjusted for estimated prepayment speed, curtailments, time to recovery, PD, and segment-specific loss given default (LGD) risk factors. The modeling of expected prepayment speeds, curtailment rates, and time to recovery are based on historical internal data and adjusted, if necessary, based on the reasonable and supportable forecast of economic conditions. For the loan segments utilizing the DCF method, (commercial, commercial real estate, and residential) management utilizes externally developed economic forecast of the following economic factors as loss drivers: national unemployment, gross domestic product and Case-Shiller U.S. National Home Price Index ("HPI"). The economic forecast is applied over a reasonable and supportable forecast period. Arrow utilizes a six quarter reasonable and supportable forecast period with an eight quarter reversion to the historic mean on a straight-line basis. The combination of adjustments for credit expectations (default and loss) and timing expectations (prepayment, curtailment, and time to recovery) produces an expected cash flow stream at the instrument level. Instrument effective yield is calculated, net of the impacts of prepayment assumptions, and the instrument expected cash flows are then discounted at that effective yield to produce an instrument-level net present value of expected cash flows (NPV). An allowance for credit loss is established for the difference between the instrument’s NPV and amortized cost basis. Arrow uses the vintage analysis method to estimate expected credit losses for the consumer loan segment. The vintage method was selected since the loans within the consumer loan segment are homogeneous, not just by risk characteristic, but by loan structure. Under the vintage analysis method, a loss rate is calculated based on the quarterly net charge-offs to the outstanding loan balance for each vintage year over the lookback period. Once this periodic loss rate is calculated for each quarter in the lookback period, the periodic rates are averaged into the loss rate. The loss rate is then applied to the outstanding loan balances based on the loan's vintage year. Arrow maintains, over the life of the loan, the loss curve by vintage year. If estimated losses computed by the vintage method need to be adjusted based on current conditions and the reasonable and supportable economic forecast, these adjustments would be incorporated over a six quarter reasonable and supportable forecast period, reverting to historical losses using a straight-line method over an eight quarter period. Based on current conditions and the reasonable and supportable economic forecast, no adjustment to the loss rate for each vintage is currently required. The vintage and DCF models also consider the need to qualitatively adjust expected loss estimates for information not already captured in the quantitative loss estimation process. Qualitative considerations include limitations inherent in the quantitative model; trends experienced in nonperforming and delinquent loans; changes in value of underlying collateral; changes in lending policies and procedures; nature and composition of loans; portfolio concentrations that may affect loss experience across one or more components or the portfolio; the experience, ability and depth of lending management and staff; Arrow's credit review system; and the effect of external factors such as competition, legal and regulatory requirements. These qualitative factor adjustments may increase or decrease Arrow's estimate of expected credit losses so that the allowance for credit loss is reflective of the estimate of lifetime losses that exist in the loan portfolio at the balance sheet date. All loans that exceed $250,000 which are on nonaccrual, are evaluated on an individual basis. For collateral dependent financial assets where Arrow has determined that foreclosure of the collateral is probable, or where the borrower is experiencing financial difficulty and Arrow expects repayment of the financial asset to be provided substantially through the operation or sale of the collateral, Arrow has elected to measure the allowance for credit loss as the difference between the fair value of the collateral less cost to sell, and the amortized cost basis of the asset as of the measurement date. In the event the repayment of a collateral dependent financial asset is expected to be provided substantially through the operation of the collateral, Arrow will use fair value of the collateral at the reporting date when recording the net carrying amount of the asset and determining the allowance for credit losses. When repayment is expected to be from the sale of the collateral, expected credit losses are calculated as the amount by which the amortized cost basis of the financial asset exceeds the fair value of the underlying collateral less estimated cost to sell. The allowance for credit losses may be zero if the fair value of the collateral at the measurement date exceeds the amortized cost basis of the financial asset. As part of ASU No. 2022-02, Arrow evaluates whether the modification represents a new loan or a continuation of an existing loan, consistent with the current GAAP treatment for other loan modifications. In addition, Arrow evaluates and if necessary, discloses if loan modifications made to borrowers experiencing financial difficulty contain a financial concession. Estimated Credit Losses on Off-Balance Sheet Credit Exposures Recognized as Other Liabilities - Arrow estimates expected credit losses over the contractual period in which Arrow has exposure to credit risk via a contractual obligation to extend credit, unless that obligation is unconditionally cancellable by Arrow. The allowance for credit losses on off-balance sheet credit exposures recognized in other liabilities, is adjusted as an expense in other non-interest expense. The estimate includes consideration of the likelihood that funding will occur and an estimate of expected credit losses on commitments expected to be funded over their estimated lives. Estimating credit losses on unfunded commitments requires Arrow to consider the following categories of off-balance sheet credit exposure: unfunded commitments to extend credit, unfunded lines of credit, and standby letters of credit. Each of these unfunded commitments is then analyzed for a probability of funding to calculate a probable funding amount. The life of loan loss factor by related portfolio segment from the loan allowance for credit loss calculation is then applied to the probable funding amount to calculate the estimated credit losses on off-balance sheet credit exposures recognized as other liabilities. Accrued Interest Receivable - Arrow has made the following elections regarding accrued interest receivable: (1) presented accrued interest receivable balances separately within the other assets balance sheet line item; (2) excluded interest receivable that is included in amortized cost of financing receivables from related disclosures requirements and (3) continued its policy to write off accrued interest receivable by reversing interest income. For loans, write off typically occurs upon becoming over 90 to 120 days past due and therefore the amount of such write offs are immaterial. Historically, Arrow has not experienced uncollectible accrued interest receivable on investment securities. Allowance for Credit Losses – Held-to-Maturity (HTM) Debt Securities - Arrow's HTM debt securities are also required to utilize the CECL approach to estimate expected credit losses. Management measures expected credit losses on HTM debt securities on a collective basis by major security types that share similar risk characteristics, such as financial asset type and collateral type adjusted for current conditions and reasonable and supportable forecasts. Management classifies the HTM portfolio into the following major security types: U.S. government agency or U.S. government sponsored mortgage-backed and collateralized mortgage obligations securities, and state and municipal debt securities. Arrow's HTM debt securities are comprised of U.S. government-sponsored enterprises (GSEs) or state and municipal obligations. GSE securities carry the explicit and/or implicit guarantee of the U.S. government, are widely recognized as “risk free,” and have a long history of zero credit loss. Therefore, Arrow did not record a credit loss for these securities. State and municipal bonds carry an investment grade from an accredited ratings agency, primarily with an investment grade rating. In addition, Arrow has a limited amount of New York state local municipal bonds that are not rated. The estimate of expected credit losses on the HTM portfolio is based on the expected cash flows of each individual CUSIP over its contractual life and utilized a municipal loss forecast model for determining PD and LGD rates. Management may exercise discretion to make adjustments based on environmental factors. A calculated expected credit loss for individual securities was determined using the PD and LGD rates. Arrow determined that the expected credit loss on its municipal bond portfolio was de minimis, and therefore, an allowance for credit losses was not recorded. Allowance for Credit Losses – Available-for-Sale (AFS) Debt Securities - Arrow's AFS debt securities are comprised of U.S. Treasuries, U.S. Government & Agency Obligations, State and Municipal Obligations, Mortgage-Backed Securities and Corporate and Other Debt Securities. The impairment model for AFS debt securities differs from the CECL approach utilized by HTM debt securities since AFS debt securities are measured at fair value rather than amortized cost. For AFS debt securities in an unrealized loss position, Arrow first assesses whether it intends to sell, or it is more likely than not that it will be required to sell the security before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the security’s amortized cost basis is written down to fair value through income. For AFS debt securities that do not meet the aforementioned criteria, in making this assessment, management considers the extent to which fair value is less than amortized cost, any changes to the rating of the security by a rating agency, adverse conditions specifically related to the security, failure of the issuer of the debt security to make scheduled interest or principal payments, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security are compared to the amortized cost basis of the security. The cash flows are estimated using information relevant to the collectability of the security, including information about past events, current conditions and reasonable and supportable forecasts. If the present value of cash flows expected to be collected is less than the amortized cost basis, a credit loss exists and an allowance for credit losses is recorded for the credit loss, limited by the amount that the fair value is less than the amortized cost basis. Any impairment that has not been recorded through an allowance for credit losses is recognized in other comprehensive income. Investments in Federal Reserve Bank ("FRB") and Federal Home Loan Bank ("FHLB") stock are required for membership in those organizations and are carried at cost since there is no market value available. The FHLB New York ("FHLBNY") continues to pay dividends and repurchase stock. As such, the Company has not recognized any impairment on its holdings of FRB and FHLB stock. Cybersecurity Risk Management, Strategy, Governance and Incident Disclosure: Cybersecurity Risk management and strategy - Annually, registrants are required to describe the processes, if any, for assessing, identifying,and managing material risks from cybersecurity threats in sufficient detail for a reasonable investor to understand those processes. The registrant must also describe whether and how any risks from cybersecurity threats, including as a result of any previous cybersecurity incidents, have materially affected or are reasonably likely to materially affect the registrant, including its business strategy, results of operations, or financial condition. Governance - Disclosure is required about management’s and the board of directors’ oversight of cybersecurity risk, including a description of the board of directors’ oversight of risks from cybersecurity threats and a description of management’s role in assessing and managing the registrant’s material risks from cybersecurity threats. The annual disclosure requirements became effective for the Company beginning with the 2023 Form 10-K.

Actual maturities will differ because issuers may have the right to call or prepay obligations with or without prepayment penalties. Arrow's investment policy requires that investments held in our portfolio be investment grade or better at the time of purchase. Arrow performs an analysis of the creditworthiness of municipal obligations to determine if a security is of investment grade. The analysis may include but may not solely rely upon credit analysis conducted by external credit rating agencies. Arrow evaluates AFS debt securities in unrealized loss positions at each measurement date to determine whether the decline in the fair value below the amortized cost basis (impairment) is due to credit-related factors or non-credit-related factors. Any impairment that is not credit related is recognized in other comprehensive income, net of applicable taxes. Credit-related impairment is recognized within the allowance for credit losses on the balance sheet, limited to the amount by which the amortized cost basis exceeds the fair value, with a corresponding adjustment to earnings via credit loss expense. Arrow determined that at June 30, 2024, gross unrealized losses were attributable to changes in interest rates, relative to when the investment securities were purchased, and not due to the credit quality of the investment securities. Arrow does not intend to sell, nor is it more likely than not that Arrow will be required to sell any securities before recovery of its amortized cost basis, which may be at maturity. Therefore, Arrow carried no allowance for credit loss at June 30, 2024 and there was no credit loss expense recognized by Arrow with respect to the securities portfolio during the three months ended June 30, 2024. Arrow's HTM debt securities are comprised of U.S. government-sponsored enterprises (GSEs) or state and municipal obligations. GSE securities carry the explicit and/or implicit guarantee of the U.S. government, are widely recognized as “risk free,” and have a long history of zero credit loss. Arrow determined that the expected credit loss on its HTM debt portfolio was immaterial and therefore no allowance for credit loss was recorded as of June 30, 2024.

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. Generally, 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, Arrow may be required to liquidate collateral at deeply discounted values. To reduce the risk, management usually obtains personal guarantees to support the borrowing, as permitted by applicable law. Commercial Real Estate - Arrow 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 typically 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, Arrow also offers commercial construction and land development loans to finance projects. Many projects will ultimately be used by the borrowers' businesses, while others are developed for resale. These real estate loans are also typically secured by first liens on the real estate, which may include apartments, commercial structures, housing businesses, 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. Arrow’s Commercial Real Estate loans are primarily located within the footprint of the Company’s branch network, with some loans extending into the greater upstate New York area. Arrow does not provide Commercial Real Estate loans in major metropolitan areas such as New York City, Boston, etc. Consumer Loans - This category is primarily comprised of automobile loans. Arrow primarily finances the purchases of automobiles indirectly through dealer relationships located throughout upstate New York and Vermont. Most automobile loans carry a fixed rate of interest with principal repayment terms typically ranging from three one Residential - Residential real estate loans consist primarily of loans secured by first or second mortgages on primary residences. Arrow originates fixed-rate and adjustable-rate one-to-four-family residential real estate loans for the construction, purchase of real estate or refinancing of an existing mortgage. These loans are collateralized primarily by owner-occupied properties generally located in Arrow's market area. Loans on one-to-four-family residential real estate are generally originated in amounts of no more than 80% of the purchase price or appraised value (whichever is lower), or have private mortgage insurance. Arrow’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 Arrow's general practice to underwrite 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, Arrow 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. Arrow's policy allows for a maximum loan to value ratio of 80%, although periodically higher advances are allowed. Arrow 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. Allowance for Credit Losses Loan segments were selected by class code and application code to ensure each segment is comprised of loans with homogenous loan characteristics and similar risk profiles. The resulting loan segments are commercial, commercial real estate, consumer and residential real estate loans. The consumer segment is mainly comprised of automobile loans, and since they are relatively short-term in nature, with similar dollar amounts and collateral, the vintage analysis method was selected to determine the credit loss reserve. The vintage method utilizes Arrow loan data exclusively as the method calculates a loss rate based on the total origination balance of the loans by year and the charge-off and recovery rate of the same origination year. Arrow maintains, over the life of the loan, the loss curve by vintage year. The discounted cash flow method (DCF) is used to calculate the reserve for credit losses for the commercial, commercial real estate and residential real estate segments. The June 30, 2024 allowance for credit losses calculation incorporated a reasonable and supportable forecast period to account for economic conditions utilized in the measurement. The quantitative model utilized a six-quarter economic forecast sourced from reputable third-parties that reflects no change in the forecasted national unemployment rate, forecasted gross domestic product projected to improve by approximately 0.17%, and the home price index (HPI) forecast to increase by approximately 2.62% from the previous quarter economic forecast. The overall change in the allowance from March 31, 2024 was primarily driven by the following factors: net loan growth contributed $0.5 million, changes in macro economic conditions reduced the allowance by $0.8 million, qualitative factors increased the allowance by $0.4 million, and net charge-offs of $0.6 million. The second quarter provision for credit losses was $775 thousand. In addition, Arrow recorded a credit for estimated credit losses on off-balance sheet credit exposures in other liabilities of $153 thousand in the second quarter of 2024. Management's evaluation considers the allowance for credit losses for loans to be appropriate as of June 30, 2024. The following table details activity in the allowance for credit losses on loans for the three and six months ended June 30, 2024 and June 30, 2023: Allowance for Credit Losses Commercial Commercial Real Estate Consumer Residential Total March 31, 2024 $ 2,842 $ 14,168 $ 2,756 $ 11,795 $ 31,561 Charge-offs $ — $ — $ (1,850) $ — $ (1,850) Recoveries $ — $ — $ 523 $ — $ 523 Provision $ (811) $ (57) $ 1,556 $ 87 $ 775 June 30, 2024 $ 2,031 $ 14,111 $ 2,985 $ 11,882 $ 31,009 December 31, 2023 $ 1,958 $ 15,521 $ 2,566 $ 11,220 $ 31,265 Charge-offs $ (9) $ — $ (3,124) $ — $ (3,133) Recoveries $ — $ — $ 1,485 $ — $ 1,485 Provision $ 82 $ (1,410) $ 2,058 $ 662 $ 1,392 June 30, 2024 $ 2,031 $ 14,111 $ 2,985 $ 11,882 $ 31,009 March 31, 2023 $ 1,737 $ 15,502 $ 2,863 $ 10,682 $ 30,784 Charge-offs $ — $ — $ (1,274) $ (6) $ (1,280) Recoveries $ — $ — $ 718 $ — $ 718 Provision $ 235 $ 195 $ 339 $ 179 $ 948 June 30, 2023 $ 1,972 $ 15,697 $ 2,646 $ 10,855 $ 31,170 December 31, 2022 $ 1,961 $ 15,213 $ 2,585 $ 10,193 $ 29,952 Charge-offs $ — $ — $ (2,602) $ (6) $ (2,608) Recoveries $ — $ — $ 1,324 $ — $ 1,324 Provision $ 11 $ 484 $ 1,339 $ 668 $ 2,502 June 30, 2023 $ 1,972 $ 15,697 $ 2,646 $ 10,855 $ 31,170 Estimated Credit Losses on Off-Balance Sheet Credit Exposures Recognized as Other Liabilities Financial instrument credit losses apply to off-balance sheet credit exposures such as unfunded loan commitments and standby letters of credit. A liability for expected credit losses for off-balance sheet exposures is recognized if the entity has a present contractual obligation to extend the credit and the obligation is not unconditionally cancellable by the entity. Changes in this allowance are reflected in other operating expenses within the non-interest expense category. As of June 30, 2024, the total unfunded commitment off-balance sheet credit exposure was $986 thousand. Individually Evaluated Loans All loans that exceed $250,000, which are on nonaccrual status, are evaluated on an individual basis. Arrow has a policy applicable to collateral dependent financial assets when the borrower is experiencing financial difficulty and the repayment is expected through the sale of the collateral. This policy allows Arrow to use fair value of the collateral at the reporting date adjusted for estimated cost to sell when recording the net carrying amount of the asset and determining the allowance for credit losses for a financial asset. In the event where the repayment of a collateral dependent financial asset is expected to be provided substantially through the operation of the collateral, Arrow will use fair value of the collateral at the reporting date when recording the net carrying amount of the asset and determining the allowance for credit losses. As of June 30, 2024, there were five total relationships identified to be evaluated for loss on an individual basis which had an amortized cost basis of $17.1 million and none had an allowance for credit loss. The following tables present the amortized cost basis of collateral-dependent loans by class of loans as of June 30, 2024, December 31, 2023 and June 30, 2023: June 30, 2024 Collateral Type -Residential Real Estate Collateral Type - Commercial Real Estate Total Loans Commercial $ — $ — $ — Commercial Real Estate — 15,179 15,179 Consumer — — — Residential 1,886 — 1,886 Total $ 1,886 $ 15,179 $ 17,065 December 31, 2023 Collateral Type -Residential Real Estate Collateral Type - Commercial Real Estate Total Loans Commercial $ — $ — $ — Commercial Real Estate — 15,308 15,308 Consumer — — — Residential 1,446 — 1,446 Total $ 1,446 $ 15,308 $ 16,754 June 30, 2023 Collateral Type -Residential Real Estate Collateral Type - Commercial Real Estate Total Loans Commercial $ — $ — $ — Commercial Real Estate — — — Consumer — — — Residential 1,963 — 1,963 Total $ 1,963 $ — $ 1,963 Allowance for Credit Losses - Collectively and Individually Evaluated Commercial Commercial Real Estate Consumer Residential Total June 30, 2024 Ending Loan Balance - Collectively Evaluated $ 163,832 $ 742,330 $ 1,138,813 $ 1,253,512 $ 3,298,487 Allowance for Credit Losses - Loans Collectively Evaluated 2,031 14,111 2,985 11,882 31,009 Ending Loan Balance - Individually Evaluated — 15,148 — 1,888 17,036 Allowance for Credit Losses - Loans Individually Evaluated — — — — — December 31, 2023 Ending Loan Balance - Collectively Evaluated $ 156,224 $ 730,179 $ 1,111,667 $ 1,198,084 $ 3,196,154 Allowance for Credit Losses - Loans Collectively Evaluated 1,958 15,521 2,566 11,220 31,265 Ending Loan Balance - Individually Evaluated — 15,308 — 1,446 16,754 Allowance for Credit Losses - Loans Individually Evaluated — — — — — June 30, 2023 Ending Loan Balance - Collectively Evaluated $ 147,518 $ 723,948 $ 1,087,765 $ 1,108,703 $ 3,067,934 Allowance for Credit Losses - Loans Collectively Evaluated 1,972 15,697 2,646 10,855 31,170 Ending Loan Balance - Individually Evaluated — — — 1,963 1,963 Allowance for Credit Losses - Loans Individually Evaluated — — — — — Through the provision for credit losses, an allowance for credit losses is maintained that reflects the best estimate of the calculated expected credit losses in Arrow's loan portfolio as of the balance sheet date. Additions are made to the allowance for credit losses through a periodic provision for credit losses. Actual credit losses are charged against the allowance for credit losses when loans are deemed uncollectible and recoveries of amounts previously charged off are recorded as credits to the allowance for credit losses. Arrow's 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, the independent internal loan review department performs periodic reviews of the credit quality indicators on individual loans in the commercial loan portfolio. Arrow considers the need to qualitatively adjust expected credit loss estimates for information not already captured in the loss estimation process. These qualitative factor adjustments may increase or decrease management’s estimate of expected credit losses. Adjustments are not made for information that has already been considered and included in the loss estimation process. Arrow considers the qualitative factors that are relevant as of the reporting date, which may include, but are not limited to the following factors: • The nature and volume of Arrow's financial assets; • The existence, growth, and effect of any concentrations of credit; • The volume and severity of past due loans, the volume of nonaccrual loans, and the volume and severity of adversely classified or graded loans; • The value of the underlying collateral for loans that are not collateral-dependent; • Arrow's lending policies and procedures, including changes in underwriting standards and practices for collections, write-offs, and recoveries; • The quality of Arrow's loan review function; • The experience, ability, and depth of Arrow's lending, investment, collection, and other relevant management/staff; • The effect of other external factors such as the regulatory, legal and technological environments; competition; and events such as natural disasters; • Actual and expected changes in international, national, regional, and local economic and business conditions and developments in which the institution operates that affect the collectability of financial assets; and • Other qualitative factors not reflected in quantitative loss rate calculations. Loan Credit Quality Indicators and Modification In 2023 and the first half of 2024, no loans met the criteria for disclosure as part of ASU 2022-02. Any modifications of loans were either immaterial in natural or were made for competitive purposes, i.e., the borrowers were not experiencing financial hardship.

For the purposes of the table above, nonperforming consumer and residential loans were those loans on nonaccrual status or were 90 days or more past due and still accruing interest. As of June 30, 2024, the amortized cost of consumer mortgage loans secured by residential real estate properties for which formal foreclosure proceedings are in process is $2.4 million. For the allowance calculation, an internally developed system of five credit quality indicators is used to rate the credit worthiness of each commercial loan defined as follows: 1) Satisfactory - "Satisfactory" borrowers have acceptable financial condition with satisfactory record of earnings and sufficient historical and projected cash flow to service the debt. 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 credit quality indicator 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 Arrow 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 (e.g. 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 with collateral 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. Commercial loans are generally evaluated on an annual basis depending on the size and complexity of the loan relationship, unless the credit related 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 in assessing the level of incurred risk of loss in our commercial related loan portfolios.

As a member of the FHLBNY, Arrow participates in the advance program which allows for overnight and term advances up to the limit of pledged collateral, including FHLBNY stock and any loans secured by real estate such as commercial real estate, residential real estate and home equity loans (see Notes 4: Investment Securities, and 5: Loans to the Consolidated Financial Statements). The maximum borrowing capacities at the FHLBNY and FRB are determined based on the fair value of the collateral pledged, subject to discounts determined by the respective lenders. As of June 30, 2024, the carrying cost for the FHLBNY collateral was approximately $861 million and approximately $1.2 billion for the FRB. As of June 30, 2024, the fair value for the FHLBNY collateral was approximately $717 million and approximately $1.2 billion for the FRB. The investment in FHLBNY stock is proportional to the total of Arrow's overnight and term advances (see the Schedule of FFRB and FHLB Stock in Note 4, Investment Securities, to the Consolidated Financial Statements). Arrow's bank subsidiaries have also established borrowing facilities with the FRB of New York for potential “discount window” advances, pledging certain consumer loans as collateral (see Note 5, Loans , to the Consolidated Financial Statements). Debt Maturities BTFP Advances - The BTFP was created to support American businesses and households by making additional funding available to eligible depository institutions to help assure banks have the ability to meet the needs of all their depositors. In the first quarter of 2024, Arrow borrowed $100 million pursuant to the BTFP. The BTFP Advances mature in January 2025 and have a weighted average interest rate of 4.76%.

The effective rate on the FHLBNY Advances is 0% due to subsidized funding in the form of interest rate credits. Long Term Debt - Guaranteed Preferred Beneficial Interests in Corporation's Junior Subordinated Debentures At June 30, 2024, the Company had two classes of financial instruments issued by two separate subsidiary business trusts of Arrow, Arrow Capital Statutory Trust II ("ACST II") and Arrow Capital Statutory Trust III ("ACST III" and, together with ACST II, the "Trusts"), identified as “Junior Subordinated Obligations Issued to Unconsolidated Subsidiary Trusts” on the Consolidated Balance Sheets and the Consolidated Statements of Income. The first of the two classes of trust-issued instruments outstanding at June 30, 2024 was issued by ACST II, a Delaware business trust established on July 16, 2003, upon the filing of a certificate of trust with the Delaware Secretary of State. In July 2003, ACST II issued all of its voting (common) stock to Arrow and issued and sold to an unaffiliated purchaser 30-year guaranteed preferred beneficial interests in the trust's assets ("ACST II TRUPS"). The rate on the securities is variable, previously adjusting quarterly to the now discontinued 3-month London Inter-Bank Offered Rate ("LIBOR") plus 3.15%. Arrow designated the Secured Overnight Financing Rate ("SOFR") as the replacement index for financial instruments. The rate on the securities are tied to the 3-month SOFR plus 3.15% post-conversion. ACST II used the proceeds of the sale of the ACST II TRUPS to purchase an identical amount of junior subordinated debentures issued by Arrow that bear an interest rate identical at all times to the rate payable on the ACST II TRUPS. The ACST II TRUPS became redeemable after July 23, 2008 and mature on July 23, 2033. The second of the two classes of trust-issued instruments outstanding at year-end was issued by ACST III, a Delaware business trust established on December 23, 2004, upon the filing of a certificate of trust with the Delaware Secretary of State. On December 28, 2004, the ACST III issued all of its voting (common) stock to Arrow and issued and sold to an unaffiliated purchaser 30-year guaranteed preferred beneficial interests in the trust's assets ("ACST III TRUPS"). The rate on the ACST III TRUPS is a variable rate, adjusting quarterly to the 3-month SOFR plus 2.00%. The rate previously adjusted quarterly to the now discontinued 3-month LIBOR plus 2.00% pre-conversion. ACST III used the proceeds of the sale of the ACST III TRUPS to purchase an identical amount of junior subordinated debentures issued by Arrow that bear an interest rate identical at all times to the rate payable on the ACST III TRUPS. The ACST III TRUPS became redeemable on or after March 31, 2010 and mature on December 28, 2034. Arrow has entered into interest rate swaps to synthetically fix the variable rate interest payments associated with $20 million in outstanding subordinated trust securities attributable to the Trusts. These agreements are designated as cash flow hedges. The primary assets of the Trusts are Arrow's junior subordinated debentures discussed above, and the sole revenues of the Trusts are payments received by them from Arrow with respect to the junior subordinated debentures. The trust preferred securities issued by the Trusts are non-voting. All common voting securities of the Trusts are owned by Arrow. Arrow used the net proceeds from its sale of junior subordinated debentures to the Trusts, facilitated by the Trusts' sale of their trust preferred securities to the purchasers thereof, for general corporate purposes. The trust preferred securities and underlying junior subordinated debentures, with associated expense that is tax deductible, qualify as Tier I capital under regulatory definitions. Arrow's primary source of funds to pay interest on the debentures that are held by the Trusts are current dividends received by Arrow from its subsidiary banks. Accordingly, Arrow's ability to make payments on the debentures, and the ability of the Trusts to make payments on their trust preferred securities, are dependent upon the continuing ability of Arrow's subsidiary banks to pay dividends to Arrow. Since the trust preferred securities issued by the subsidiary trusts and the underlying junior subordinated debentures issued by Arrow at June 30, 2024, December 31, 2023, and June 30, 2023 are classified as debt for financial statement purposes, the expense associated with these securities is recorded as interest expense in the Consolidated Statements of Income for the three years.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	COMMITMENTS AND CONTINGENCIES (In Thousands) The following table presents the notional amount and fair value of Arrow's off-balance sheet commitments to extend credit and commitments under standby letters of credit as of June 30, 2024, December 31, 2023 and June 30, 2023: Commitments to Extend Credit and Letters of Credit June 30, 2024 December 31, 2023 June 30, 2023 Notional Amount: Commitments to Extend Credit $ 435,597 $ 444,256 $ 463,224 Standby Letters of Credit 3,987 3,824 4,114 Fair Value: Commitments to Extend Credit $ — $ — $ — Standby Letters of Credit (5) — 11 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. Those 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 not expected to be fully 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 lines of credit 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 does not issue any guarantees that would require liability-recognition or disclosure, other than its standby letters of credit. 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 commercial 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, 2024, December 31, 2023 and June 30, 2023 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. Arrow's policies governing loan collateral apply to standby letters of credit at the time of credit extension. Loan-to-value ratios will 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 range from 1% to 3% of the notional amount. Fees are collected upfront and amortized over the life of the commitment. The carrying amount and fair value of Arrow's standby letters of credit at June 30, 2024, December 31, 2023 and June 30, 2023, were insignificant. 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. Except as noted below, Arrow, including its subsidiary banks, is not currently the subject of any material pending legal proceedings, other than ordinary routine litigation occurring in the normal course of their business. On an ongoing basis, Arrow is often the subject of, or a party to, various legal claims by other parties against Arrow, by Arrow against other parties, or involving Arrow, which arise in the normal course of business. Except as noted below, the various pending legal claims against Arrow will not, in the opinion of management based upon consultation with counsel, result in any material liability. Legal expenses incurred in connection with loss contingencies are expensed as incurred. As previously disclosed in certain of the Company’s filings with the SEC, on June 23, 2023, Robert C. Ashe filed a putative class action complaint (the "Ashe Lawsuit") against the Company in the United States District Court for the Northern District of New York. In addition to the Company, the complaint names as defendants Thomas J. Murphy, the Company’s former CEO and from September 30, 2022 to February 20, 2023, its interim CFO, Edward J. Campanella, the Company’s former CFO, and Penko Ivanov, the Company’s current CFO (“Individual Defendants” and, together with the Company, the "Defendants"). The complaint alleges that the Defendants made materially false and misleading statements regarding the Company’s business, operations and compliance policies in the Company’s public filings between March 12, 2022 and May 12, 2023. The complaint further alleges that the Individual Defendants are liable for these materially false and misleading statements as "controlling persons" of the Company. Based on these allegations, the complaint brings two claims for violations of Section 10(b) of the Exchange Act and Rule 10b-5 promulgated thereunder and of Section 20(a) of the Exchange Act. Mr. Ashe, on behalf of a purported class of shareholders, seeks compensatory damages as well as recovery of the costs and fees associated with the litigation. On December 5, 2023, Mr. Ashe filed an amended complaint that changed the putative class period to the period from August 5, 2022 through May 12, 2023, but challenged substantially the same statements on the same basis. On February 9, 2024, the Company moved to dismiss the action in its entirety. On April 22, 2024, the parties reached an agreement in principle to settle the matter, subject to final documentation and court approval. Management believes that the terms of the proposed settlement will not have a material adverse impact on the Company’s financial results. In the event that the parties are not able to finalize a settlement, the Company intends to continue to vigorously defend against the claims asserted in the Ashe Lawsuit. On December 12, 2023 the Company became aware that Stephen Bull filed a complaint (the "Shareholder Derivative Complaint") on behalf of Arrow against the three individual defendants in the Ashe Lawsuit as well as against all members of Arrow’s board of directors during the class period in Ashe. The Company is named solely as a nominal defendant in the action and would be the beneficiary of any recovery. The Shareholder Derivative Complaint alleges breaches of fiduciary duty (i) by the Ashe individual defendants based on substantially the same allegedly misleading statements pleaded in the Ashe complaint; and (ii) the director defendants by failing adequately to oversee the individual defendants and maintain internal and disclosure controls. Plaintiffs seek (i) unspecified damages (which would be payable to the Company) for costs incurred as a result of the alleged misstatements, including costs of investigation, remediation, and litigation, (ii) repayment of the director defendants’ compensation on an unjust enrichment theory, and (iii) an order directing the Company to take all necessary actions to reform and improve its corporate governance, and (iv) the recovery of costs and fees associated with the litigation. The Shareholder Derivative Complaint also asserts various federal securities claims based on the same alleged misrepresentations as set forth in the Ashe Lawsuit. The Company is in active settlement negotiations in this matter and expects to reach a resolution in the not too distant future. Management believes that any settlement to be reached will not have a material adverse impact on the Company’s financial results. In the event that the parties are not able to reach a settlement, the Company intends to continue to vigorously defend itself against the Shareholder Derivative Complaint.

Stock-Based Compensation	Jun. 30, 2024
Share-Based Payment Arrangement [Abstract]
Stock-Based Compensation	STOCK-BASED COMPENSATION (Dollars In Thousands, Except Share and Per Share Amounts) Arrow has established three stock-based compensation plans: a Long Term Incentive Plan, an Employee Stock Purchase Plan (ESPP) and an Employee Stock Ownership Plan (ESOP). All share and per share data have been adjusted for the September 26, 2023 3% stock dividend. Long Term Incentive Plan The Long Term Incentive Plan provides for the grant of incentive stock options, non-qualified stock options, restricted stock awards, restricted stock units, performance units and performance shares. The Compensation Committee of the Board of Directors administers the Long Term Incentive Plan. Restricted Stock Awards - In May 2024, the Company granted restricted stock awards which will generally vest over a four-year period. Unvested restricted stock will generally be forfeited if the recipient ceases to be employed by the Company, with limited exceptions. Grantees of restricted stock awards are entitled to receive all dividends and distributions declared and paid on restricted stock, or cash payments equivalent to such dividends or distributions, including those declared and paid during the vesting period.

The fair value of each restricted stock unit is the market value of Company stock on the date of grant. 100% of the restricted stock unit awards vest three years from the grant date, unless vested or forfeited prior to vesting in accordance with the terms of the award. Once vested, the restricted stock units are no longer forfeitable. Vested units settle upon retirement, as defined in the Arrow retirement plan, of the recipient. Unvested restricted stock unit awards will generally be forfeited if the recipient ceases to be employed by the Company, with limited exceptions. There were no restricted stock units outstanding at any time during the three or six month periods ended June 30, 2024.

In October 2023, the Board of Directors approved the adoption of a new ESPP intended to satisfy the requirements of Section 423 of the Internal Revenue Code, which was effective January 1, 2024 (the "Qualified ESPP"). Under the Qualified ESPP, the amount of the discount is 10% below market price. Under the Prior ESPP, the amount of the discount was 5% below market price. Under current accounting guidance, a stock purchase plan with a discount of 5% or less is not considered a compensatory plan. The Qualified ESPP is considered a compensatory plan. The Qualified ESPP was approved by Arrow shareholders at the annual meeting of shareholders on June 5, 2024. Employee Stock Ownership Plan Arrow maintains an ESOP, pursuant to which substantially all employees of Arrow and its subsidiaries are eligible to participate upon satisfaction of applicable service requirements. The Company may make, and historically has made, a cash contribution to the ESOP each year.

Retirement Benefits [Abstract]
Retirement Benefit Plans	RETIREMENT BENEFIT PLANS (Dollars in Thousands) Arrow sponsors qualified and non-qualified defined benefit pension plans and other postretirement benefit plans for its employees. Arrow maintains a non-contributory pension plan, which covers substantially all employees. Effective December 1, 2002, all active participants in the qualified defined benefit pension plan were given a one-time irrevocable election to continue participating in the traditional plan design, for which benefits were based on years of service and the participant’s final compensation (as defined), or to begin participating in the new cash balance plan design. All employees who first participate in the plan after December 1, 2002 automatically participate in the cash balance plan design. The interest credits under the cash balance plan are based on the 30-year U.S. Treasury rate in effect for November of the prior year with a minimum interest credit of 3%. The service credits under the cash balance plan are equal to 6.0% of eligible salaries for employees who become participants on or after January 1, 2003. For employees in the plan prior to January 1, 2003, the service credits are scaled based on the age of the participant, and range from 6.0% to 12.0%. The funding policy is to contribute up to the maximum amount that can be deducted for federal income tax purposes and to make all payments required under The Employee Retirement Income Security Act (ERISA). Arrow also maintains a supplemental non-qualified unfunded retirement plan to provide eligible employees of Arrow and its subsidiaries with benefits in excess of qualified plan limits imposed by federal tax law. Arrow has multiple non-pension postretirement benefit plans. The health care, dental and life insurance plans are contributory, with participants’ contributions adjusted annually. Arrow’s policy is to fund the cost of postretirement benefits based on the current cost of the underlying policies. However, the health care plan provision allows for grandfathered participants to receive automatic increases of Company contributions each year based on the increase in inflation, limited to a maximum of 5%. As of December 31, 2023, Arrow uses the sex-distinct Amount-Weighted Pri-2012 Mortality Tables for employees, healthy retirees and contingent survivors, with mortality improvements projected using Scale MP-2021 on a generational basis for the Pension Plan and the sex-distinct Amount-Weighted White Collar Pri-2012 Mortality Tables for employees, healthy retirees and contingent survivors, with mortality improvements projected using Scale MP-2021 on a generational basis for the Select Executive Retirement Plan (the "SERP"). Segment interest rates of 5.50%, 5.76%, 5.83% were used in determining the present value of a lump sum payment/annuitizing cash balance accounts as of December 31, 2023. Effective January 1, 2021, GFNB amended the Arrow Financial Corporation Employees' Pension Plan (the "Plan"). The Plan change was adopted January 1, 2021 and the amendment was valued as of December 31, 2020. The Plan amendment was as follows: Effective January 1, 2021, the benefit payable to or on behalf of each participant: • whose employment with the Employer (or any predecessor Employer, except as noted below) terminated on or before • who satisfied the requirements for early, normal, or late retirement as of such termination; • who never participated in the United Vermont Bancorporation Plan; and • who is, or whose beneficiary is, receiving monthly benefit payments from the Plan as of January 1, 2021 (including a The foregoing increase was applied to the monthly benefit actually payable to the participant, or to the participant's beneficiary, as of January 1, 2021, determined after all applicable adjustments, regardless of whether such benefit had been determined under the Company's plan or the plan of a predecessor employer that had been merged into the Plan. The plan amendment caused a $351,638 increase in the projected benefit obligation, creating a positive service cost which will be amortized over 9.70 years (the average expected future service of active plan participants.) Effective January 1, 2021, GFNB amended the Arrow Financial Corporation Employees' SERP. The plan change was adopted January 1, 2021 and the amendment was valued as of December 31, 2020. The plan amendment provides a special adjustment to the monthly benefit payment for certain retirees. The plan amendment caused a $122,797 increase in the projected benefit obligation, creating a positive prior service cost which will be amortized over 12.5 years. Settlement accounting is required when lump sum payments during a fiscal year exceed that fiscal year's Service Cost plus Interest Cost components of the Net Periodic Pension Cost. For 2022, the sum of the Service Cost and Interest Cost was $3.3 million and the 2022 total lump sum payments exceeded that amount. The Plan therefore recognized in the 2022 Net Periodic Pension Cost a portion of the Unamortized Net (Gain)/Loss equal to the ratio of the projected benefit obligation for the participants that received a lump sum to the total projected benefit obligation. As of December 31, 2022, the Unamortized Net Loss prior to reflecting settlement accounting was $7.2 million. The ratio of the projected benefit obligation for participants that received a lump sum to the total projected benefit obligation was 8.06%. The effect of the settlement that was recognized in the 2022 Net Periodic Pension Cost was $577 thousand, which was fully reflected in the 2022 Net Periodic Cost. Settlement accounting was not required for the the year ended December 31, 2023 or for the three- or six-month periods ended June 30, 2024. The following tables provide the components of net periodic benefit costs for the three-month and six-month periods ended June 30, 2024 and 2023: Employees' Select Executive Postretirement Pension Retirement Benefit Plan Plan Plans Net Periodic Benefit Cost For the Three Months Ended June 30, 2024: Service Cost 1 $ 380 $ 22 $ 8 Interest Cost 2 595 2 79 Expected Return on Plan Assets 2 (923) — — Amortization of Prior Service Cost 2 33 10 25 Amortization of Net Gain 2 — (9) (82) Net Periodic Cost $ 85 $ 25 $ 30 Plan Contributions During the Period $ — $ 128 $ 54 For the Three Months Ended June 30, 2023: Service Cost 1 $ 384 $ 122 $ 10 Interest Cost 2 519 97 80 Expected Return on Plan Assets 2 (851) — — Amortization of Prior Service Cost 2 15 10 26 Amortization of Net Loss (Gain) 2 23 19 (98) Net Periodic Cost $ 90 $ 248 $ 18 Plan Contributions During the Period $ — $ 110 $ 20 Net Periodic Benefit Cost For the Six Months Ended June 30, 2024: Service Cost 1 $ 846 $ 39 $ 23 Interest Cost 2 1,120 160 160 Expected Return on Plan Assets 2 (1,855) — — Amortization of Prior Service Cost 2 66 20 51 Amortization of Net Loss (Gain) 2 — 12 (169) Net Periodic Cost $ 177 $ 231 $ 65 Plan Contributions During the Period $ — $ 255 $ 81 Estimated Future Contributions in the Current Fiscal Year $ — $ 255 $ 81 For the Six Months Ended June 30, 2023: Service Cost 1 $ 797 $ 285 $ 28 Interest Cost 2 1,049 159 167 Expected Return on Plan Assets 2 (1,708) — — Amortization of Prior Service Cost 2 31 20 52 Amortization of Net Loss (Gain) 2 59 37 (177) Net Periodic Cost $ 228 $ 501 $ 70 Plan Contributions During the Period $ — $ 226 $ 47 Footnotes: 1.

Fair Value Disclosures [Abstract]
Fair Values	FAIR VALUES (Dollars In Thousands) FASB ASC Subtopic 820-10 defines fair value, establishes a framework for measuring fair value in GAAP and requires certain disclosures about fair value measurements. There are no nonfinancial assets or liabilities measured at fair value on a recurring basis. The only assets or liabilities that Arrow measured at fair value on a recurring basis at June 30, 2024, December 31, 2023 and June 30, 2023 were AFS securities, equity securities and derivatives. Arrow held no securities or liabilities for trading on such dates. The table below presents the financial instrument's fair value and the amounts within the fair value hierarchy based on the lowest level of input that is significant to the fair value measurement: Fair Value of Assets and Liabilities Measured on a Recurring and Nonrecurring Basis Fair Value Measurements at Reporting Date Using: Fair Value Quoted Prices Significant Other Significant Unobservable Inputs Fair Value of Assets and Liabilities Measured on a Recurring Basis: June 30, 2024 Assets: Securities Available-for Sale: U.S. Treasuries $ 49,456 $ — $ 49,456 $ — U.S. Government & Agency Obligations 153,353 — 153,353 $ — State and Municipal Obligations 240 — 240 — Mortgage-Backed Securities 246,790 — 246,790 — Corporate and Other Debt Securities 947 — 947 — Total Securities Available-for-Sale 450,786 — 450,786 — Equity Securities 1,996 — 1,996 — Total Securities Measured on a Recurring Basis 452,782 — 452,782 — Derivative Assets 12,180 — 12,180 — Total Measured on a Recurring Basis $ 464,962 $ — $ 464,962 $ — Fair Value of Assets and Liabilities Measured on a Recurring and Nonrecurring Basis Fair Value Measurements at Reporting Date Using: Fair Value Quoted Prices Significant Other Significant Unobservable Inputs Liabilities: Derivative Liabilities 6,445 — 6,445 — Total Measured on a Recurring Basis $ 6,445 $ — $ 6,445 $ — December 31, 2023 Assets: Securities Available-for Sale: U.S. Treasuries $ 74,004 $ — $ 74,004 $ — U.S. Government & Agency Obligations 152,925 — 152,925 — State and Municipal Obligations 280 — 280 — Mortgage-Backed Securities 269,760 — 269,760 — Corporate and Other Debt Securities 800 — 800 — Total Securities Available-for-Sale 497,769 — 497,769 — Equity Securities 1,925 — 1,925 — Total Securities Measured on a Recurring Basis 499,694 — 499,694 — Derivative Assets 12,057 — 12,057 — Total Measured on a Recurring Basis $ 511,751 $ — $ 511,751 $ — Liabilities: Derivative Liabilities $ 9,598 $ — $ 9,598 $ — Total Measured on a Recurring Basis $ 9,598 $ — $ 9,598 $ — June 30, 2023 Assets: Securities Available-for Sale: U.S. Government & Agency Obligations $ 176,016 $ — $ 176,016 $ — State and Municipal Obligations 280 — 280 — Mortgage-Backed Securities 366,612 — 366,612 — Corporate and Other Debt Securities 800 — 800 — Total Securities Available-for-Sale 543,708 — 543,708 — Equity Securities 1,889 — 1,889 — Total Securities Measured on a Recurring Basis 545,597 — 545,597 — Derivative Assets 7,457 — 7,457 — Total Measured on a Recurring Basis $ 553,054 $ — $ 553,054 $ — Liabilities: Derivative Liabilities 7,457 — 7,457 — Total Measured on a Recurring Basis $ 7,457 $ — $ 7,457 $ — Fair Value Quoted Prices Significant Other Significant Unobservable Inputs Gains (Losses) Recognized in Earnings Fair Value of Assets and Liabilities Measured on a Nonrecurring Basis: June 30, 2024 Collateral Dependent Evaluated Loans $ — $ — $ — $ — Other Real Estate Owned and Repossessed Assets, Net 273 — — 273 — December 31, 2023 Collateral Dependent Impaired Loans $ — $ — $ — $ — Other Real Estate Owned and Repossessed Assets, Net 312 — — 312 — June 30, 2023 Collateral Dependent Impaired Loans $ — $ — $ — $ — Other Real Estate Owned and Repossessed Assets, Net 524 — — 524 — The fair value of financial instruments is determined under the following hierarchy: • Level 1 - Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities; • Level 2 - Quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, or inputs that are observable, either directly or indirectly, for substantially the full term of the asset or liability; and, • Level 3 - Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (i.e., supported by little or no market activity). Fair Value Methodology for Assets and Liabilities Measured on a Recurring Basis The fair value of Level 1 AFS securities are based on unadjusted, quoted market prices from exchanges in active markets. The fair value of Level 2 AFS securities 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 services use 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. The fair value of Level 2 equities are based on the last observable price in open markets. The fair value of Level 2 equities are based on the last observable price in open markets. The fair value of Level 2 derivatives is determined using inputs that are observable in the market place obtained from third parties including yield curves, publicly available volatilities, and floating indexes. Fair Value Methodology for Assets and Liabilities Measured on a Nonrecurring Basis The fair value of collateral dependent evaluated loans and other real estate owned was based on third-party appraisals less estimated cost to sell. The appraisals may be adjusted by management for qualitative factors such as economic conditions and estimated liquidation expenses. 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 at least annually, with no impairment recognized for these assets at June 30, 2024, December 31, 2023 and June 30, 2023.

Leases [Abstract]
Leases	LEASES (Dollars In Thousands) Arrow is a lessee in its leases, which are mainly for financial services locations in addition to leases for corporate vehicles. These leases generally require Arrow to pay third-party expenses on behalf of the Lessor, which are referred to as variable payments. Under some leases, Arrow pays the variable payments to the lessor, and in other leases, Arrow pays the variable payments directly to the applicable third party. None of Arrow's current leases include any residual value guarantees or any subleases, and there are no significant rights and obligations of Arrow for leases that have not commenced as of the reporting date. Arrow leases two of its branch offices, at market rates, from Stewart’s Shops Corp. Additionally on June 14th, 2024, Arrow entered into a sale-leaseback agreement with Stewart’s Shops Corp. for a bank branch location. The sale price of the property was $1.1 million which resulted in a gain of $377 thousand. The lease agreement began in June 2024 and runs through May 2029, with rent totaling $5 thousand per month for the remainder of the lease. Mr. Gary C.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments and Hedging Activities	DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES (In Thousands) Arrow is exposed to certain risks arising from both its business operations and economic conditions. Arrow principally manages its exposures to a wide variety of business and operational risks through management of its core business activities. Arrow manages economic risks, including interest rate, primarily by managing the amount, sources and duration of its assets and liabilities and through the use of derivative instruments. Specifically, Arrow enters into derivative financial instruments to manage exposures that arise from business activities that result in the receipt or payment of future known and uncertain cash amounts, the value of which are determined by interest rates. Arrow's derivative financial instruments are used to manage differences in the amount, timing and duration of known or expected cash receipts and its known or expected cash payments principally related to certain fixed rate borrowings. Arrow also has interest rate derivatives that result from a service provided to certain qualifying customers and, therefore, are not used to manage interest rate risk in Arrow's assets or liabilities. Arrow's goal is to have a matched book with respect to its derivative instruments in order to minimize its net risk exposure resulting from such transactions. Derivatives Not Designated as Hedging Instruments Arrow enters into interest rate swap agreements with its commercial customers to provide them with a long-term fixed rate, while simultaneously entering into offsetting interest rate swap agreements with a counterparty to swap the fixed rate to a variable rate to manage interest rate exposure. These interest rate swap agreements are not designated as a hedge for accounting purposes. As the interest rate swap agreements have substantially equivalent and offsetting terms, they do not present material exposure to Arrow's consolidated statements of income. Arrow records its interest rate swap agreements at fair value and is presented on a gross basis within other assets and other liabilities on the consolidated balance sheets. Changes in the fair value of assets and liabilities arising from these derivatives are included, net, in other income in the consolidated statement of income. The following table depicts the fair value adjustment recorded related to the notional amount of derivatives, not designated as hedging instruments, outstanding as well as the notional amount of the interest rate swap agreements: Derivatives Not Designated as Hedging Instruments - Interest Rate Swap Agreements June 30, 2024 December 31, 2023 June 30, 2023 Fair value adjustment included in other assets $ 6,053 $ 6,208 $ 7,457 Fair value adjustment included in other liabilities 6,053 6,208 7,457 Notional amount 106,967 123,197 125,503 Derivatives Designated as Hedging Instruments Arrow entered into two pay-fixed portfolio layer method ("PLM") fair value swaps, designated as hedging instruments, with a total notional amount of $250 million and $50 million, respectively, in the third quarter of 2023. Arrow is designating the fair value swaps under PLM. Under PLM, the hedged items are designated as hedged layers of a closed portfolio of financial loans that are anticipated to remain outstanding for the designated hedged period. Adjustments will be made to record the swaps at fair value on the Consolidated Balance Sheets, with changes in fair value recognized in interest income. The carrying value of the fair value swaps on the Consolidated Balance Sheets will also be adjusted through interest income, based on changes in fair value attributable to changes in the hedged risk. The following table depicts the fair value adjustment recorded related to the notional amount of derivatives, designed as hedging instruments, outstanding as well as the notional amount of the interest rate swap agreements: Derivatives Designated as Hedging Instruments - Fair Value Agreements June 30, 2024 December 31, 2023 June 30, 2023 Fair value adjustment included in other assets $ — $ — $ — Fair value adjustment included in other liabilities 392 5,678 — Notional amount 300,000 300,000 — The following table summarizes the effect of the fair value hedging relationship recognized on the unaudited interim consolidated statement of income: Derivatives Designated as Hedging Instruments - Fair Value Agreements Six Months Ended Twelve Months Ended Six Months Ended June 30, 2024 December 31, 2023 June 30, 2023 Hedged Asset $ 366 $ 5,849 $ — Fair value derivative designated as hedging instrument (392) (5,828) — Total (loss) gain recognized in the consolidated statements of income with interest and fees on loans (26) 21 — The following table represents the carrying value of the PLM hedged assets and the cumulative fair value hedging adjustment included in the carrying value of the hedged asset: Derivatives Designated as Hedging Instruments - Fair Value Swap Agreements June 30, 2024 December 31, 2023 June 30, 2023 Carrying Value of Portfolio Layer Method Hedged Asset $ 300,366 $ 305,849 $ — Cumulative Fair Value Hedging Adjustment 366 5,849 — In the fourth quarter of 2023, Arrow entered into two interest rate swaps, designated as hedging instruments, to add stability to interest expense and to manage its exposure to the variability of the future cash flows attributable to the contractually specified interest rates. The notional amounts were $100 million and $75 million, respectively. Arrow entered into pay-fixed interest rate swaps to convert rolling 90 days brokered deposits. For derivatives that qualify as cash flow hedges of interest rate risk, the gain or loss on the derivative is recorded in Accumulated Other Comprehensive Income ("AOCI") and subsequently reclassified into interest expense in the same period during which the hedge transaction affects earnings. The following table indicates the effect of cash flow hedge accounting on AOCI and on the consolidated statement of income.

These agreements are designated as cash flow hedges. For derivatives that qualify as cash flow hedges of interest rate risk, the gain or loss on the derivative is recorded in AOCI and subsequently reclassified into interest expense in the same period during which the hedge transaction affects earnings. Amounts reported in AOCI related to derivatives will be reclassified to interest expense as interest payments are made on Arrow's Junior Subordinated Obligations Issued to Unconsolidated Subsidiary Trusts borrowings.

Accounting Policies [Abstract]
Recently Issued Accounting Standards	Recently Issued Accounting Standards In March 2020, the FASB issued ASU 2020-04, "Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting." On January 7, 2021, the FASB issued ASU 2021-01, which refines the scope of ASC 848 and clarifies some of its guidance. The ASU and related amendments provide temporary optional expedients and exceptions to the existing guidance for applying GAAP to affected contract modifications and hedge accounting relationships in the transition away from the LIBOR or other interbank offered rate on financial reporting. The guidance also allows a one-time election to sell and/or reclassify to AFS or trading HTM debt securities that reference an interest rate affected by reference rate reform. The amendments in this ASU are effective March 12, 2020 through December 31, 2022 and permit relief solely for reference rate reform actions and different elections over the effective date for legacy and new activity. In December 2022, FASB issued ASU 2022-06, "Reference Rate Reform (Topic 848)" which deferred the sunset date of Topic 848 to December 31, 2024, to allow for a transition period after the sunset of LIBOR. Arrow does not expect ASU 2022-06 will have a material impact on its consolidated financial statements. In November 2023, the FASB issued ASU No. 2023-07, Segment Reporting: Improvements to Reportable Segment Disclosures. This ASU amends FASB Topic 280 to permit the disclosure of multiple measures of a segment's profit or loss, and requires an entity with a single reportable segment to apply FASB Topic 280 in its entirety. In addition, this ASU requires new segment disclosures. Arrow does not expect this new standard will have a material impact on the consolidated financial statements. In December 2023, the FASB issued ASU 2023-09,1 which establishes new income tax disclosure requirements in addition to modifying and eliminating certain existing requirements. Under the new guidance, entities must consistently categorize and provide greater disaggregation of information in the rate reconciliation. They must also further disaggregate income taxes paid. Arrow does not expect this new standard will have a material impact on the consolidated financial statements.
Management's Use of Estimates	Management’s Use of Estimates The preparation of the consolidated financial statements in conformity with accounting principles generally accepted in the United States of America (GAAP) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of income and expenses during the reporting period. Management utilized estimates and assumptions in its evaluation of potential impairment of Arrow's right-of-use lease assets, goodwill and intangible assets. Our most significant estimate is the allowance for credit losses. Other estimates include the fair value of financial instruments, evaluation of pension and other post-retirement liabilities, an analysis of a need for a valuation allowance for deferred tax assets and a reserve for unfunded loan commitments recorded as an other liability. Actual results could differ from those estimates. A material estimate that is particularly susceptible to significant change in the near term is the allowance for credit losses. In connection with the determination of the allowance for credit losses management obtains economic forecasts from reliable sources and appraisals for properties. The allowance for credit losses is management’s best estimate of the life of loan losses as of the balance sheet date. While management uses available information to recognize losses on loans, future adjustments to the allowance for credit losses may be necessary based on changes in economic conditions.
Allowance for Credit Losses	Allowance for Credit Losses – Loans - Accounting Standards Update (ASU) 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (CECL) approach requires an estimate of the credit losses expected over the life of a loan (or pool of loans). It replaces the incurred loss approach’s threshold that required the recognition of a credit loss when it was probable that a loss event was incurred. The allowance for credit losses is a valuation account that is deducted from, or added to, the loans’ amortized cost basis to present the net lifetime amount expected to be collected on the loans. Credit losses are charged off against the allowance when management believes a loan balance is confirmed to be uncollectible. Expected recoveries do not exceed the aggregate of amounts previously charged off and expected to be charged off. Management estimates the allowance using relevant available information from internal and external sources related to past events, current conditions, and a reasonable and supportable single economic forecast. Historical credit loss experience provides the basis for the estimation of expected credit losses. Arrow's historical loss experience is supplemented with peer information when there is insufficient loss data for Arrow. Peer selection is based on a review of institutions with comparable loss experience as well as loan yield, bank size, portfolio concentration and geography. Adjustments to historical loss information are made for differences in current loan-specific risk characteristics such as differences in credit concentrations, delinquency level, collateral values and underwriting standards as well as changes in economic conditions or other relevant factors. Management judgment is required at each point in the measurement process. Portfolio segment is defined as the level at which an entity develops and documents a systematic methodology to determine its allowance for credit losses. Management developed portfolio segments for estimating loss based on type of borrower and collateral as follows: Commercial Loans Commercial Real Estate Loans Consumer Loans Residential Loans Further details related to loan portfolio segments is included in Note 5 Loans. Historical credit loss experience for both Arrow and segment-specific peers provides the basis for the estimation of expected credit losses. Arrow utilized regression analyses of peer data where observed credit losses and selected economic factors were utilized to determine suitable loss drivers for modeling lifetime probability of default (PD) rates. Arrow uses the discounted cash flow (DCF) method to estimate expected credit losses for the commercial, commercial real estate, and residential segments. For each of these loan segments, Arrow generates cash flow projections at the instrument level wherein payment expectations are adjusted for estimated prepayment speed, curtailments, time to recovery, PD, and segment-specific loss given default (LGD) risk factors. The modeling of expected prepayment speeds, curtailment rates, and time to recovery are based on historical internal data and adjusted, if necessary, based on the reasonable and supportable forecast of economic conditions. For the loan segments utilizing the DCF method, (commercial, commercial real estate, and residential) management utilizes externally developed economic forecast of the following economic factors as loss drivers: national unemployment, gross domestic product and Case-Shiller U.S. National Home Price Index ("HPI"). The economic forecast is applied over a reasonable and supportable forecast period. Arrow utilizes a six quarter reasonable and supportable forecast period with an eight quarter reversion to the historic mean on a straight-line basis. The combination of adjustments for credit expectations (default and loss) and timing expectations (prepayment, curtailment, and time to recovery) produces an expected cash flow stream at the instrument level. Instrument effective yield is calculated, net of the impacts of prepayment assumptions, and the instrument expected cash flows are then discounted at that effective yield to produce an instrument-level net present value of expected cash flows (NPV). An allowance for credit loss is established for the difference between the instrument’s NPV and amortized cost basis. Arrow uses the vintage analysis method to estimate expected credit losses for the consumer loan segment. The vintage method was selected since the loans within the consumer loan segment are homogeneous, not just by risk characteristic, but by loan structure. Under the vintage analysis method, a loss rate is calculated based on the quarterly net charge-offs to the outstanding loan balance for each vintage year over the lookback period. Once this periodic loss rate is calculated for each quarter in the lookback period, the periodic rates are averaged into the loss rate. The loss rate is then applied to the outstanding loan balances based on the loan's vintage year. Arrow maintains, over the life of the loan, the loss curve by vintage year. If estimated losses computed by the vintage method need to be adjusted based on current conditions and the reasonable and supportable economic forecast, these adjustments would be incorporated over a six quarter reasonable and supportable forecast period, reverting to historical losses using a straight-line method over an eight quarter period. Based on current conditions and the reasonable and supportable economic forecast, no adjustment to the loss rate for each vintage is currently required. The vintage and DCF models also consider the need to qualitatively adjust expected loss estimates for information not already captured in the quantitative loss estimation process. Qualitative considerations include limitations inherent in the quantitative model; trends experienced in nonperforming and delinquent loans; changes in value of underlying collateral; changes in lending policies and procedures; nature and composition of loans; portfolio concentrations that may affect loss experience across one or more components or the portfolio; the experience, ability and depth of lending management and staff; Arrow's credit review system; and the effect of external factors such as competition, legal and regulatory requirements. These qualitative factor adjustments may increase or decrease Arrow's estimate of expected credit losses so that the allowance for credit loss is reflective of the estimate of lifetime losses that exist in the loan portfolio at the balance sheet date. All loans that exceed $250,000 which are on nonaccrual, are evaluated on an individual basis. For collateral dependent financial assets where Arrow has determined that foreclosure of the collateral is probable, or where the borrower is experiencing financial difficulty and Arrow expects repayment of the financial asset to be provided substantially through the operation or sale of the collateral, Arrow has elected to measure the allowance for credit loss as the difference between the fair value of the collateral less cost to sell, and the amortized cost basis of the asset as of the measurement date. In the event the repayment of a collateral dependent financial asset is expected to be provided substantially through the operation of the collateral, Arrow will use fair value of the collateral at the reporting date when recording the net carrying amount of the asset and determining the allowance for credit losses. When repayment is expected to be from the sale of the collateral, expected credit losses are calculated as the amount by which the amortized cost basis of the financial asset exceeds the fair value of the underlying collateral less estimated cost to sell. The allowance for credit losses may be zero if the fair value of the collateral at the measurement date exceeds the amortized cost basis of the financial asset. As part of ASU No. 2022-02, Arrow evaluates whether the modification represents a new loan or a continuation of an existing loan, consistent with the current GAAP treatment for other loan modifications. In addition, Arrow evaluates and if necessary, discloses if loan modifications made to borrowers experiencing financial difficulty contain a financial concession. Estimated Credit Losses on Off-Balance Sheet Credit Exposures Recognized as Other Liabilities - Arrow estimates expected credit losses over the contractual period in which Arrow has exposure to credit risk via a contractual obligation to extend credit, unless that obligation is unconditionally cancellable by Arrow. The allowance for credit losses on off-balance sheet credit exposures recognized in other liabilities, is adjusted as an expense in other non-interest expense. The estimate includes consideration of the likelihood that funding will occur and an estimate of expected credit losses on commitments expected to be funded over their estimated lives. Estimating credit losses on unfunded commitments requires Arrow to consider the following categories of off-balance sheet credit exposure: unfunded commitments to extend credit, unfunded lines of credit, and standby letters of credit. Each of these unfunded commitments is then analyzed for a probability of funding to calculate a probable funding amount. The life of loan loss factor by related portfolio segment from the loan allowance for credit loss calculation is then applied to the probable funding amount to calculate the estimated credit losses on off-balance sheet credit exposures recognized as other liabilities. Accrued Interest Receivable - Arrow has made the following elections regarding accrued interest receivable: (1) presented accrued interest receivable balances separately within the other assets balance sheet line item; (2) excluded interest receivable that is included in amortized cost of financing receivables from related disclosures requirements and (3) continued its policy to write off accrued interest receivable by reversing interest income. For loans, write off typically occurs upon becoming over 90 to 120 days past due and therefore the amount of such write offs are immaterial. Historically, Arrow has not experienced uncollectible accrued interest receivable on investment securities. Allowance for Credit Losses – Held-to-Maturity (HTM) Debt Securities - Arrow's HTM debt securities are also required to utilize the CECL approach to estimate expected credit losses. Management measures expected credit losses on HTM debt securities on a collective basis by major security types that share similar risk characteristics, such as financial asset type and collateral type adjusted for current conditions and reasonable and supportable forecasts. Management classifies the HTM portfolio into the following major security types: U.S. government agency or U.S. government sponsored mortgage-backed and collateralized mortgage obligations securities, and state and municipal debt securities. Arrow's HTM debt securities are comprised of U.S. government-sponsored enterprises (GSEs) or state and municipal obligations. GSE securities carry the explicit and/or implicit guarantee of the U.S. government, are widely recognized as “risk free,” and have a long history of zero credit loss. Therefore, Arrow did not record a credit loss for these securities. State and municipal bonds carry an investment grade from an accredited ratings agency, primarily with an investment grade rating. In addition, Arrow has a limited amount of New York state local municipal bonds that are not rated. The estimate of expected credit losses on the HTM portfolio is based on the expected cash flows of each individual CUSIP over its contractual life and utilized a municipal loss forecast model for determining PD and LGD rates. Management may exercise discretion to make adjustments based on environmental factors. A calculated expected credit loss for individual securities was determined using the PD and LGD rates. Arrow determined that the expected credit loss on its municipal bond portfolio was de minimis, and therefore, an allowance for credit losses was not recorded. Allowance for Credit Losses – Available-for-Sale (AFS) Debt Securities - Arrow's AFS debt securities are comprised of U.S. Treasuries, U.S. Government & Agency Obligations, State and Municipal Obligations, Mortgage-Backed Securities and Corporate and Other Debt Securities. The impairment model for AFS debt securities differs from the CECL approach utilized by HTM debt securities since AFS debt securities are measured at fair value rather than amortized cost. For AFS debt securities in an unrealized loss position, Arrow first assesses whether it intends to sell, or it is more likely than not that it will be required to sell the security before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the security’s amortized cost basis is written down to fair value through income. For AFS debt securities that do not meet the aforementioned criteria, in making this assessment, management considers the extent to which fair value is less than amortized cost, any changes to the rating of the security by a rating agency, adverse conditions specifically related to the security, failure of the issuer of the debt security to make scheduled interest or principal payments, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security are compared to the amortized cost basis of the security. The cash flows are estimated using information relevant to the collectability of the security, including information about past events, current conditions and reasonable and supportable forecasts. If the present value of cash flows expected to be collected is less than the amortized cost basis, a credit loss exists and an allowance for credit losses is recorded for the credit loss, limited by the amount that the fair value is less than the amortized cost basis. Any impairment that has not been recorded through an allowance for credit losses is recognized in other comprehensive income. Investments in Federal Reserve Bank ("FRB") and Federal Home Loan Bank ("FHLB") stock are required for membership in those organizations and are carried at cost since there is no market value available. The FHLB New York ("FHLBNY") continues to pay dividends and repurchase stock. As such, the Company has not recognized any impairment on its holdings of FRB and FHLB stock.
