SUMMARY OF SIGNIFICANT ACCOUNTI

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	12 Months Ended
	Dec. 31, 2015
Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation and Consolidation The consolidated financial statements (the “financial statements”) of Berkshire Hills Bancorp, Inc. and its subsidiaries (the “Company” or “Berkshire”) have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”). The Company is a Delaware corporation and the holding company for Berkshire Bank (the “Bank”), a Massachusetts-chartered savings bank headquartered in Pittsfield, Massachusetts, and Berkshire Insurance Group, Inc. (“Berkshire Insurance Group” or “BIG”). These financial statements include the accounts of the Company, its wholly-owned subsidiaries and the Bank’s consolidated subsidiaries. In consolidation, all significant intercompany accounts and transactions are eliminated. The results of operations of companies or assets acquired are included only from the dates of acquisition. All material wholly-owned and majority-owned subsidiaries are consolidated unless GAAP requires otherwise. Reclassifications Certain items in prior financial statements have been reclassified to conform to the current presentation. The Company has evaluated subsequent events for potential recognition and/or disclosure through the date these consolidated financial statements were issued. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent liabilities at the date of the financial statements. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses; the valuation of deferred tax assets; the estimates related to the initial measurement of goodwill and intangible assets and subsequent impairment analyses; the determination of other-than-temporary impairment of securities; and the determination of fair value of financial instruments and subsequent impairment analysis. Business Combinations Business combinations are accounted for using the acquisition method of accounting. Under this method, the accounts of an acquired entity are included with the acquirer’s accounts as of the date of acquisition with any excess of purchase price over the fair value of the net assets acquired (including identifiable intangibles) capitalized as goodwill. To consummate an acquisition, the Company will typically issue common stock and/or pay cash, depending on the terms of the acquisition agreement. The value of common shares issued is determined based upon the market price of the stock as of the closing of the acquisition. Cash and Cash equivalents Cash and cash equivalents include cash, balances due from banks, and short-term investments, all of which mature within ninety days. Due to the nature of cash and cash equivalents and the near term maturity, the Company estimated that the carrying amount of such instruments approximated fair value. The nature of the Bank’s business requires that it maintain amounts due from banks which at times, may exceed federally insured limits. The Bank has not experienced any losses on such amounts and all amounts are maintained with well-capitalized institutions. Trading Security The Company accounts for a tax advantaged economic development bond originated in 2008 at fair value, in accordance with Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification (“ASC”) 320. The bond has been designated as a trading account security and is recorded at fair value, with changes in unrealized gains and losses recorded through earnings each period as part of non-interest income. Securities Debt securities that management has the intent and ability to hold to maturity are classified as held to maturity and carried at amortized cost. All other securities, including equity securities with readily determinable fair values, are classified as available for sale and carried at fair value, with unrealized gains and losses reported as a component of other net comprehensive income. Management determines the appropriate classification of securities at the time of purchase. Restricted equity securities, such as stock in the Federal Home Loan Bank of Boston (“FHLBB”) are carried at cost. There are no quoted market prices for the Company’s restricted equity securities. The Bank is a member of the FHLBB, which requires that members maintain an investment in FHLBB stock, which may be redeemed based on certain conditions. The Bank reviews for impairment based on the ultimate recoverability of the cost bases in the FHLBB stock. Purchase premiums and discounts are recognized in interest income using the interest method over the terms of the securities. Gains and losses on the sale of securities are recorded on the trade date and are determined using the specific identification method. The Company evaluates debt and equity securities within the Company’s available for sale and held to maturity portfolios for other-than-temporary impairment (“OTTI”), at least quarterly. If the fair value of a debt security is below the amortized cost basis of the security, OTTI is required to be recognized if any of the following are met: (1) the Company intends to sell the security; (2) it is “more likely than not” that the Company will be required to sell the security before recovery of its amortized cost basis; or (3) the present value of expected cash flows is not sufficient to recover the entire amortized cost basis. For all impaired debt securities that the Company intends to sell, or more likely than not will be required to sell, the full amount of the depreciation is recognized as OTTI through earnings. Credit-related OTTI for all other impaired debt securities is recognized through earnings. Non-credit related OTTI for such debt securities is recognized in other comprehensive income, net of applicable taxes. In evaluating its marketable equity securities portfolios for OTTI, the Company considers its intent and ability to hold an equity security to recovery of its cost basis in addition to various other factors, including the length of time and the extent to which the fair value has been less than cost and the financial condition and near term prospects of the issuer. Any OTTI on marketable equity securities is recognized immediately through earnings. Loans Held for Sale Loans originated with the intent to be sold in the secondary market are accounted for under the fair value option. Non-refundable fees and direct loan origination costs related to residential mortgage loans held for sale are recognized in noninterest income or noninterest expense as earned or incurred. Fair value is primarily determined based on quoted prices for similar loans in active markets. Gains and losses on sales of residential mortgage loans (sales proceeds minus carrying value) are recorded in noninterest income. Loans that were previously held for investment that the Company has an active plan to sell are transferred to loans held for sale at the lower of cost or market (fair value). The market price is primarily determined based on quoted prices for similar loans in active markets or agreed upon sales prices. Gains are recorded in noninterest income at sale to the extent that the sale price of the loan exceeds carrying value. Any reduction in the loan’s value, prior to being transferred to loans held for sale, is reflected as a charge-off of the recorded investment in the loan resulting in a new cost basis, with a corresponding reduction in the allowance for loan losses. Further changes in the fair value of the loan are recognized in noninterest income or expense, accordingly. Loans Loans are reported at their outstanding unpaid principal balances adjusted for charge-offs, the allowance for loan losses, the unamortized balance of any deferred fees or costs on originated loans and the unamortized balance of any premiums or discounts on loans purchased or acquired through mergers. Interest income is accrued on the unpaid principal balance. Interest income includes net accretion or amortization of deferred fees or costs and of premiums or discounts. Direct loan origination costs, net of any origination fees, in addition to premiums and discounts on loans, are deferred and recognized as an adjustment of the related loan yield using the interest method. Interest on loans, excluding automobile loans, is generally not accrued on loans which are ninety days or more past due unless the loan is well-secured and in the process of collection. Past due status is based on contractual terms of the loan. Automobile loans generally continue accruing until one hundred and twenty days delinquent, at which time they are charged off. All interest accrued but not collected for loans that are placed on non-accrual or charged-off is reversed against interest income, except for certain loans designated as well-secured. The interest on non-accrual loans is accounted for on the cash-basis or cost-recovery method, until qualifying for return to accrual. All payments received on non-accrual loans are applied against the principal balance of the loan. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured. Acquired Loans Loans that the Company acquired in acquisitions are initially recorded at fair value with no carryover of the related allowance for credit losses. Determining the fair value of the loans involves estimating the amount and timing of principal and interest cash flows initially expected to be collected on the loans and discounting those cash flows at an appropriate market rate of interest. For loans that meet the criteria stipulated in ASC 310-30, “ Loans and Debt Securities Acquired with Deteriorated Credit Quality, ” the Company recognizes the accretable yield, which is defined as the excess of all cash flows expected at acquisition over the initial fair value of the loan, as interest income on a level-yield basis over the expected remaining life of the loan. The excess of the loan’s contractually required payments over the cash flows expected to be collected is the nonaccretable difference. The nonaccretable difference is not recognized as an adjustment of yield, a loss accrual, or a valuation allowance. Going forward, the Company continues to evaluate whether the timing and the amount of cash to be collected are reasonably expected. Subsequent significant increases in cash flows the Company expects to collect will first reduce any previously recognized valuation allowance and then be reflected prospectively as an increase to the level yield. Subsequent decreases in expected cash flows may result in the loan being considered impaired. Interest income is not recognized to the extent that the net investment in the loan would increase to an amount greater than the estimated payoff amount. For ASC 310-30 loans, the expected cash flows reflect anticipated prepayments, determined on a loan by loan basis according to the anticipated collection plan of these loans. The expected prepayments used to determine the accretable yield are consistent between the cash flows expected to be collected and projections of contractual cash flows so as to not affect the nonaccretable difference. For ASC 310-30 loans, prepayments result in the recognition of the nonaccretable balance as current period yield. Changes in prepayment assumptions may change the amount of interest income and principal expected to be collected. Interest income is also net of recoveries recorded on acquired impaired loans. For loans that do not meet the ASC 310-30 criteria, the Company accretes interest income based on the contractually required cash flows. The Company subjects loans that do not meet the ASC 310-30 criteria to ASC 450, “Contingencies” by collectively evaluating these loans for an allowance for loan loss. Acquired loans that met the criteria for nonaccrual of interest prior to the acquisition are considered performing upon acquisition, regardless of whether the customer is contractually delinquent, if the Company can reasonably estimate the timing and amount of the expected cash flows on such loans and if the Company expects to fully collect the new carrying value of the loans. As such, the Company may no longer consider the loan to be nonaccrual or nonperforming and may accrue interest on these loans, including the impact of any accretable yield. The Company has determined that the Company can reasonably estimate future cash flows on the Company’s current portfolio of acquired loans that are past due 90 days or more and on which the Company is accruing interest and the Company expects to fully collect the carrying value of the loans. Allowance for Loan Losses The allowance for loan losses is established based upon the level of estimated probable losses in the current loan portfolio. Loan losses are charged against the allowance when management believes the collectability of a loan balance is doubtful. Subsequent recoveries, if any, are credited to the allowance. The allowance for loan losses includes allowance allocations calculated in accordance with ASC 310, “Receivables,” and allowance allocations calculated in accordance with ASC 450, “Contingencies.” The allowance for loan losses is allocated to loan types using both a formula-based approach applied to groups of loans and an analysis of certain individual loans for impairment. The formula-based approach emphasizes loss factors derived from actual historical and industry portfolio loss rates, which are combined with an assessment of certain qualitative factors to determine the allowance amounts allocated to the various loan categories. Allowance amounts are based on an estimate of historical average annual percentage rate of loan loss for each loan segment, a temporal estimate of the incurred loss emergence and confirmation period for each loan category, and certain qualitative risk factors considered in the computation of the allowance for loan losses. Qualitative risk factors impacting the inherent risk of loss within the portfolio include the following: • National and local economic conditions, regulatory/legislative changes, or other competitive factors affecting the collectability of the portfolio • Trends in underwriting characteristics, composition of the portfolio, and/or asset quality • Changes in underwriting standards and/or collection, charge off, recovery, and account management practice • The existence and effect of any concentrations of credit Risk characteristics relevant to each portfolio segment are as follows: Residential mortgage — The Company generally does not originate loans with a loan-to-value ratio greater than 80 percent and does not grant subprime loans. The Company requires private mortgage insurance (PMI) in cases when the loan-to-value ratio exceeds 80 percent . All loans in this segment are collateralized by residential real estate and repayment is dependent on the credit quality of the individual borrower. The overall health of the economy, including unemployment rates and housing prices, will have an effect on the credit quality in this segment. Commercial real estate — Loans in this segment are primarily owner-occupied or income-producing properties throughout New England and Northeastern New York. The underlying cash flows generated by the properties are adversely impacted by a downturn in the economy, which in turn, will have an effect on the credit quality in this segment. Management monitors the cash flows of these loans. In addition, construction loans in this segment primarily include real estate development loans for which payment is derived from sale of the property or long term financing at completion. Credit risk is affected by cost overruns, time to sell at an adequate price, and market conditions. Commercial and industrial loans — Loans in this segment are made to businesses and are generally secured by assets of the business. Repayment is expected from the cash flows of the business. Loans in this segment include asset based loans which generally have no scheduled repayment and which are closely monitored against formula based collateral advance ratios. A weakened economy, and resultant decreased consumer spending, will have an effect on the credit quality in this segment. Consumer loans — Loans in this segment are primarily home equity lines of credit and second mortgages, together with automobile loans and other consumer loans. The overall health of the economy, including unemployment rates and housing prices, will have an effect on the credit quality in this segment. The Company utilizes a blend of historical and industry portfolio loss rates for commercial mortgage and commercial business loans that are assessed by internal risk rating. Historical loss rates for residential mortgages, home equity and other consumer loans are not risk graded but are assessed based on the total of each loan segment. This approach incorporates qualitative adjustments based upon management’s assessment of various market and portfolio specific risk factors into its formula-based estimate. Due to the imprecise nature of the loan loss estimation process and ever changing conditions, the qualitative risk attributes may not adequately capture amounts of incurred loss in the formula-based loan loss components used to determine allocations in the Company’s analysis of the adequacy of the allowance for loan losses. The Company evaluates certain loans individually for specific impairment. Large groups of small balance homogeneous loans such as the residential mortgage, home equity, and other consumer portfolios are collectively evaluated for impairment. A loan is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered by management in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Loans are selected for evaluation based upon a change in internal risk rating, occurrence of delinquency, loan classification, or non-accrual status. The evaluation of certain loans individually for specific impairment includes loans that were previously classified as Troubled Debt Restructurings (“TDRs”) or continue to be classified as TDRs. A specific allowance amount is allocated to an individual loan when such loan has been deemed impaired and when the amount of the probable loss is able to be estimated. Estimates of loss may be determined by the present value of anticipated future cash flows or the loan’s observable fair market value, or the fair value of the collateral, if the loan is collateral dependent. However, for collateral dependent loans, the amount of the recorded investment in a loan that exceeds the fair value of the collateral is charged-off against the allowance for loan losses in lieu of an allocation of a specific allowance amount when such an amount has been identified definitively as uncollectible. Bank-Owned Life Insurance Bank-owned life insurance policies are reflected on the consolidated balance sheets at cash surrender value. Changes in the net cash surrender value of the policies, as well as insurance proceeds received, are reflected in non-interest income on the consolidated statements of operations and are not subject to income taxes. Foreclosed and Repossessed Assets Assets acquired through, or in lieu of, loan foreclosure or repossession are held for sale and are initially recorded at the lower of the investment in the loan or fair value less estimated costs to sell at the date of foreclosure or repossession, establishing a new cost basis. Subsequently, valuations are periodically performed by management and the assets are carried at the lower of carrying amount or fair value less estimated costs to sell. Revenue and expenses from operations, changes in the valuation allowance, any direct write-downs and gains or losses on sales are included in other real estate owned expense. Capitalized Mortgage Servicing Rights Capitalized mortgage servicing rights are included in “other assets” in the consolidated balance sheet. Servicing assets are initially recognized as separate assets at fair value when rights are acquired through purchase or through sale of financial assets with servicing retained. The Company uses the amortization method to subsequently measure servicing assets. Under that method, capitalized mortgage servicing rights are charged to expense in proportion to and over the period of estimated net servicing income. Fair value of the mortgage servicing rights is based on a valuation model that calculates the present value of estimated future net servicing income. The valuation model incorporates assumptions that market participants would use in estimating future net servicing income, such as the cost to service, the discount rate, prepayment speeds and default rates and losses. Impairment is recognized through a valuation allowance for an individual tranche, to the extent that fair value is less than the capitalized amount for the tranches. If the Company later determines that all or a portion of the impairment no longer exists for a particular tranche, a reduction of the allowance may be recorded as an increase to income. Premises and Equipment Land is carried at cost. Buildings, improvements, and equipment are carried at cost, less accumulated depreciation and amortization computed on the straight-line method over the estimated useful lives of the assets. Leasehold improvements are amortized over the initial term of the lease, plus optional terms if certain conditions are met. Goodwill Goodwill represents the excess of the purchase price over the fair value of the net assets acquired in a business combination. Goodwill is assigned to reporting units, which are operating segments or one level below an operating segment. Goodwill is assigned to the Company’s reporting units that are expected to benefit from the business combination. Goodwill is assessed annually for impairment, and more frequently if events or changes in circumstances indicate that there may be an impairment. Adverse changes in the economic environment, declining operations, unanticipated competition, loss of key personnel, or other factors could result in a decline in the implied fair value of goodwill. If the implied fair value of goodwill is less than the carrying amount, a loss would be recognized in other noninterest expense to reduce the carrying amount to the implied fair value of goodwill. A goodwill impairment analysis is comprised of two steps. Step 1, used to identify instances of potential impairment, compares the fair value of a reporting unit with its carrying amount, including goodwill. If the fair value of a reporting unit exceeds its carrying amount, including goodwill, the reporting unit’s goodwill is not considered impaired. If the carrying amount of a reporting unit, including goodwill, exceeds its fair value, the second step of the goodwill impairment analysis is performed to measure the amount of impairment loss, if any. Step 2 of the goodwill impairment analysis compares the implied fair value of reporting unit goodwill with the carrying amount of that goodwill. If the carrying amount of goodwill for that reporting unit exceeds the implied fair value of that reporting unit’s goodwill, an impairment loss is recognized in an amount equal to that excess. Subsequent reversals of goodwill impairment are prohibited. Other Intangibles Intangible assets are acquired assets that lack physical substance but can be distinguished from goodwill because of contractual or other legal rights or the asset is capable of being sold or exchanged either on its own or in combination with a related contract, asset or liability. The fair values of these assets are generally determined based on appraisals and are subsequently amortized on a straight-line basis or an accelerated basis over their estimated lives. Management assesses the recoverability of these intangible assets whenever events or changes in circumstances indicate that their carrying value may not be recoverable. If the carrying amount exceeds fair value, an impairment charge is recorded to income. Transfers of Financial Assets Transfers of an entire financial asset, group of entire financial assets, or a participating interest in an entire financial asset are accounted for as sales when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when (1) the assets have been isolated from the Company, (2) the transferee obtains the right to pledge or exchange the transferred assets, and (3) the Company does not maintain effective control over the transferred assets. Income Taxes Deferred income taxes are recognized for the tax consequences of temporary differences by applying enacted statutory tax rates applicable for future years to differences between financial statement and tax bases of existing assets and liabilities. The effect of tax rate changes on deferred taxes is recognized in the income tax provision in the period that includes the enactment date. A tax valuation allowance is established, as needed, to reduce net deferred tax assets to the amount expected to be realized. In the event it becomes more likely than not that some or all of the deferred tax asset allowances will not be needed, the valuation allowance will be adjusted. In the ordinary course of business there is inherent uncertainty in quantifying the Company’s income tax positions. Income tax positions and recorded tax benefits are based upon management’s evaluation of the facts, circumstances, and information available at the reporting date. For those tax positions where it is more likely than not that a tax benefit will be sustained, we have determined the amount of the tax benefit to be recognized by estimating the largest amount of tax benefit that has a greater than 50% likelihood of being realized upon ultimate settlement with a taxing authority that has full knowledge of all relevant information. For those income tax positions where it is not more-likely-than-not that a tax benefit will be sustained, no tax benefit has been recognized in the financial statements. Where applicable, associated interest and penalties has also been recognized. We recognize accrued interest and penalties related to unrecognized tax benefits as a component of income tax expense. Insurance Commissions Commission revenue is recognized as of the effective date of the insurance policy or the date the customer is billed, whichever is later, net of return commissions related to policy cancellations. In addition, the Company may receive additional performance commissions based on achieving certain sales and loss experience measures. Such commissions are recognized when determinable, which is generally when such commissions are received or when the Company receives data from the insurance companies that allows the reasonable estimation of these amounts. Advertising Costs Advertising costs are expensed as incurred. Stock-Based Compensation The Company measures and recognizes compensation cost relating to share-based payment transactions based on the grant-date fair value of the equity instruments issued. The fair value of restricted stock is recorded as unearned compensation. The deferred expense is amortized to compensation expense based on one of several permitted attribution methods over the longer of the required service period or performance period. For performance-based restricted stock awards, the Company estimates the degree to which performance conditions will be met to determine the number of shares that will vest and the related compensation expense. Compensation expense is adjusted in the period such estimates change. Income tax benefits related to stock compensation in excess of grant date fair value, less any proceeds on exercise, are recognized as an increase to additional paid-in capital upon vesting or exercising and delivery of the stock. Any income tax benefits that are less than grant date fair value less any proceeds on exercise would be recognized as a reduction of additional paid-in capital to the extent of previously recognized income tax benefits and then as compensation expense for the remaining amount. Earnings per Common Share Basic earnings per share represents income available to common stockholders divided by the weighted-average number of common shares outstanding during the period. If rights to dividends on unvested options/awards are non-forfeitable, these unvested awards/options are considered outstanding in the computation of basic earnings per share. Diluted earnings per share reflects additional common shares that would have been outstanding if dilutive potential common shares had been issued, as well as any adjustments to income that would result from the assumed issuance. Potential common shares that may be issued by the Company relate to outstanding stock options and restricted stock awards and are determined using the treasury stock method. Treasury shares are not deemed outstanding for earnings per share calculations. Wealth Management Wealth management assets held in a fiduciary or agent capacity are not included in the accompanying consolidated balance sheets because they are not assets of the Company. Fees earned from wealth management activities are amortized over the period of the service performed. Derivative Instruments and Hedging Activities The Company enters into interest rate swap agreements as part of the Company’s interest rate risk management strategy for certain assets and liabilities and not for speculative purposes. Based on the Company’s intended use for the interest rate swap at inception, the Company designates the derivative as either an economic hedge of an asset or liability or a hedging instrument subject to the hedge accounting provisions of ASC 815, “Derivatives and Hedging.” Interest rate swaps designated as economic hedges are recorded at fair value within other assets or liabilities. Changes in the fair value of these derivatives are recorded directly through earnings. For interest rate swaps that management intends to apply the hedge accounting provisions of ASC 815, the Company formally documents at inception all relationships between hedging instruments and hedged items, as well as its risk management objectives and strategies for undertaking the various hedges. Additionally, the Company uses dollar offset or regression analysis at the hedge’s inception and for each reporting period thereafter, to assess whether the derivative used in its hedging transaction is expected to be and has been highly effective in offsetting changes in the fair value or cash flows of the hedged item. The Company discontinues hedge accounting when it is determined that a derivative is not expected to be or has ceased to be highly effective as a hedge, and then reflects changes in fair value of the derivative in earnings after termination of the hedge relationship. The Company has characterized its interest rate swaps that qualify under ASC 815 hedge accounting as cash flow hedges. Cash flow hedges are used to minimize the variability in cash flows of assets or liabilities, or forecasted transactions caused by interest rate fluctuations, and are recorded at fair value in other assets or liabilities within the Company’s balance sheets. Changes in the fair value of these cash flow hedges are initially recorded in accumulated other comprehensive loss and subsequently reclassified into earnings when the forecasted transaction affects earnings. Any hedge ineffectiveness assessed as part of the Company’s quarterly analysis is recorded directly to earnings. The Company enters into interest rate lock commitments with borrowers, and forward commitments to sell loans or to-be-announced mortgage-backed bonds to investors to hedge against the inherent interest rate and pricing risk associated with selling loans. The interest rate lock commitments generally terminate once the loan is funded, the lock period expires or the borrower decides not to contract for the loan. The forward commitments generally t

Business Combinations [Abstract]
ACQUISITIONS	ACQUISITIONS Hampden Bancorp, Inc. On April 17, 2015, the Company acquired all of the outstanding common shares of Hampden Bancorp, Inc. (“Hampden”). Hampden, as a holding company, had one banking subsidiary (“Hampden Bank”) that had ten branches primarily serving western Massachusetts. As a result of the transaction, Hampden merged into Berkshire Hills Bancorp, and Hampden Bank merged into Berkshire Bank. This business combination increases Berkshire’s market share in its franchise and the goodwill recognized results from the expected synergies and earnings accretion from this combination, including future cost savings related to Hampden’s operations. On the acquisition date, Hampden had 5.167 million outstanding common shares, net of 209 thousand shares held by Berkshire Bank. Hampden shareholders received 4.186 million the Company's common shares based on an exchange ratio of 0.81 shares of the Company's common stock for each Hampden share. The 4.355 million shares of the Company's common stock issued in this exchange were valued at $27.38 per share based on the closing price posted on April 17, 2015. Excluding the 169 thousand shares issued to Berkshire Bank, this resulted in a consideration value of $114.6 million . The preliminary consideration value was reduced by $130 thousand , resulting in a final consideration value of $114.5 million . The reduction in preliminary consideration value was due to six thousand shares of Hampden common shares held by the Hampden’s stock compensation plan and not released to common stock holders. These shares were subsequently converted to five thousand Berkshire common shares based on an exchange ratio of 0.81 shares of Berkshire common stock for each Hampden share and recorded in the Company’s treasury stock. The Hampden shares held by Berkshire Bank were valued at $4.6 million , and the value in excess of the carrying value was recorded as a $2.2 million gain on securities, net in the statement of income. The following table provides a summary of the assets acquired and liabilities assumed as recorded by Hampden and the associated provisional fair value adjustments. As provided for under GAAP, management has a measurement period of up to 12 months following the date of acquisition to finalize the fair values of the acquired assets and assumed liabilities to reflect new information obtained about facts and circumstances that existed as of the acquisition date. Once management has finalized the fair values within the measurement period, management considers such values to be the day one fair values. The table summarizes the estimates of the resultant fair values of those assets and liabilities as recorded by the Company; no material adjustments were made since the provisional estimates were recorded at June 30, 2015. Fair Value As Recorded by (in thousands) As Acquired Adjustments the Company Consideration paid: Berkshire Hills Bancorp common stock issued to Hampden common stockholders $ 114,470 Fair value of Hampden shares previously owned by the Company prior to acquisition 4,632 Total consideration paid 119,102 Recognized amounts of identifiable assets acquired and (liabilities) assumed, at fair value: Cash and short-term investments $ 83,134 $ — $ 83,134 Investment securities 72,439 (224 ) (a) 72,215 Loans 501,870 (8,405 ) (b) 493,465 Premises and equipment 4,449 775 (c) 5,224 Core deposit intangibles — 2,780 (d) 2,780 Deferred tax assets, net 3,875 2,723 (e) 6,598 Other assets 22,919 856 (f) 23,775 Deposits (482,130 ) (1,439 ) (g) (483,569 ) Borrowings (117,135 ) (1,396 ) (h) (118,531 ) Other liabilities (8,395 ) (107 ) (i) (8,502 ) Total identifiable net assets $ 81,026 $ (4,437 ) $ 76,589 Goodwill $ 42,513 ________________________________ Explanation of Certain Fair Value Adjustments (a) The adjustment represents the write down of the book value of securities to their estimated fair value based on estimates at the date of acquisition. (b) The adjustment represents the write down of the book value of loans to their estimated fair value based on interest rates and expected cash flows as of the acquisition date, which includes an estimate of expected loan loss inherent in the portfolio. Loans that met the criteria and are being accounted for in accordance with ASC 310-30 had a carrying amount of $28.5 million and had a fair value of $16.7 million . Non-impaired loans not accounted for under ASC 310-20 had a book value of $473.4 million and have a fair value of $477.1 million . ASC 310-30 loans have a $4.0 million fair value adjustment that is accretable in earnings over an estimated five -year life using the effective yield as determined on the date of acquisition. The effective yield is periodically adjusted for changes in expected flows. ASC 310-20 loans have a $0.4 million fair value adjustment premium that is amortized into expense over the remaining term of the loans using the effective interest method, or a straight-line method if the loan is a revolving credit facility. (c) The amount represents the adjustment of the book value of buildings, and furniture and equipment, to their estimated fair value based on appraisals and other methods. The adjustments will be depreciated over the estimated economic lives of the assets. (d) The adjustment represents the value of the core deposit base assumed in the acquisition. The core deposit asset was recorded as an identifiable intangible asset and will be amortized over the estimated useful life of the deposit base. (e) Represents net deferred tax assets resulting from the fair value adjustments related to the acquired assets and liabilities, identifiable intangibles, and other purchase accounting adjustments. (f) The amount consists of a $0.2 million fair value adjustment to write-down other real estate owned based on market report data, a $0.3 million write-down of mortgage servicing assets acquired based on valuation reports, a $0.5 million write-off of prepaid assets due to obsolescence, and a $1.6 million measurement period adjustment increase to current taxes receivable. These adjustments are not accretable into earnings in the statement of income. (g) The adjustment is necessary because the weighted average interest rate of time deposits exceeded the cost of similar funding at the time of acquisition. The amount will be amortized using an accelerated method over the estimated useful life of two years. (h) Adjusts borrowings to their estimated fair value, which is calculated based on the expected future cash flow of the borrowings. (i) Adjusts the book value of other liabilities to their estimated fair value at the acquisition date. The adjustment consists of a $0.4 million write-off of deferred revenue, a $0.3 million increase to post-retirement liabilities due to change-in-control provisions, and a $0.2 million increase related to non-level leases. Except for collateral dependent loans with deteriorated credit quality, the fair values for loans acquired were estimated using cash flow projections based on the remaining maturity and repricing terms. Cash flows were adjusted by estimating future credit losses and the rate of prepayments. Projected monthly cash flows were then discounted to present value using a risk-adjusted market rate for similar loans. For collateral dependent loans with deteriorated credit quality, the Company estimated fair value by analyzing the value of the underlying collateral of the loans, assuming the fair values of the loans were derived from the eventual sale of the collateral. Those values were discounted using market derived rates of return, with consideration given to the period of time and costs associated with the foreclosure and disposition of the collateral. There was no carryover of the seller’s allowance for credit losses associated with the loans acquired, as the loans were initially recorded at fair value. Information about the Hampden acquired loan portfolio subject to ASC 310-30 as of April 17, 2015 is as follows (in thousands): ASC 310-30 Loans Gross contractual receivable amounts at acquisition $ 28,505 Contractual cash flows not expected to be collected (nonaccretable discount) (7,884 ) Expected cash flows at acquisition 20,621 Interest component of expected cash flows (accretable premium) (3,950 ) Fair value of acquired loans $ 16,671 The goodwill, which is not amortized for book purposes, was assigned to our banking reporting unit and is not deductible for tax purposes. The fair value of savings and transaction deposit accounts acquired in the Hampden acquisition was assumed to approximate the carrying value as these accounts have no stated maturity and are payable on demand. The fair value of time deposits was estimated by discounting the contractual future cash flows using market rates offered for time deposits of similar remaining maturities. The Company’s consolidated results of operations include the operating results of Hampden beginning April 17, 2015, the date of acquisition, through the end of the reporting period. Direct acquisition and integration costs of the Hampden acquisition were expensed as incurred, and totaled $11.1 million during the year ended December 31, 2015 and there were $1.5 million for the same period of 2014. For whole-bank acquisitions, the Company has determined it is impractical to report the amounts of revenue and earnings of each entity since acquisition date -- including Hampden. Due to the integration of their operations with those of the organization, the Company does not record revenue and earnings separately. The revenue and earnings of these operations are included in the Consolidated Statement of Income. Firestone Financial Corp. On August 7, 2015, the Company acquired all of the outstanding common shares of Firestone Financial Corp. (“Firestone”). Firestone is located in Needham, Massachusetts and is engaged in providing equipment financing for amusement, vending, laundry, and fitness industries nationwide. Firestone continues to operate as a wholly-owned subsidiary of Berkshire Bank. This business combination broadens the Company's product mix and revenue streams. The goodwill recognized results from the expected earnings accretion from the acquisition of this niche lender. Based on the merger agreement, Firestone shareholders received 1.442 million shares of the Company's common stock and $13.9 million in cash. The 1.442 million shares of the Company's common stock issued for this transaction was valued at $29.20 per share based on the closing price posted on August 6, 2015, resulting in a stock consideration value of $42.1 million . Additionally, the Company extinguished Firestone’s $11.8 million commercial loan from Berkshire Bank, resulting in a $67.3 million total consideration paid for the acquisition of Firestone. The following table provides a summary of the assets acquired and liabilities assumed as recorded by Firestone and the associated provisional fair value adjustments. As provided for under GAAP, management has a measurement period of up to 12 months following the date of acquisition to finalize the fair values of the acquired assets and assumed liabilities to reflect new information obtained about facts and circumstances that existed as of the acquisition date. The table summarizes the estimates of the resultant fair values of those assets and liabilities as recorded by the Company; no material adjustments were made since the provisional estimates were recorded at September 30, 2015. Consideration paid, and fair values of Firestone’s assets acquired and liabilities assumed, along with the resulting goodwill, are summarized in the following table: Fair Value As Recorded by (in thousands) As Acquired Adjustments the Company Consideration Paid: Berkshire Hills Bancorp common stock issued to Firestone common stockholders $ 42,107 Cash paid to Firestone common stockholders 13,887 Total merger consideration (1) $ 55,994 Recognized amounts of identifiable assets acquired and (liabilities) assumed, at fair value: Cash $ 4,577 $ — $ 4,577 Loans 194,622 (2,668 ) (a) 191,954 Premises and equipment 1,356 (835 ) (b) 521 Deferred tax assets, net 162 2,850 (c) 3,012 Other assets 1,863 (1,002 ) (d) 861 Borrowings (1) (159,312 ) — (159,312 ) Other liabilities (3,198 ) 76 (e) (3,122 ) Total identifiable net assets $ 40,070 $ (1,579 ) $ 38,491 Goodwill $ 17,503 (1) Amounts exclude $11.8 million of Firestone's commercial loan with the Company, which was effectively settled upon acquisition. Amounts also include a $0.5 million in-transit cash payment to Firestone common stockholders. ________________________________ Explanation of Certain Fair Value Adjustments (a) The adjustment represents a write-down of the book value of loans to their estimated fair value based on current interest rates and expected cash flows, which includes an estimate of expected loan loss inherent in the portfolio. Loans that met the criteria and are being accounted for in accordance with ASC 310-30 had a book value of $5.4 million and had a fair value $1.5 million . Non-impaired loans accounted for under ASC 310-20 had a book value of $192.7 million and had a fair value of $190.4 million . ASC 310-30 loans included a $0.8 million fair value adjustment that is accretable in earnings over an estimated three year life using the effective yield as determined on the date of acquisition. The effective yield is periodically adjusted for changes in expected flows. ASC 310-20 loans have a $2.3 million fair value adjustment discount that is amortized into earnings over the remaining term of the loans using the effective interest method. (b) The adjustment is a write-off of capitalized costs associated with Firestone’s internally developed accounting software, the development of which has been ceased due to pending conversion of Firestone’s accounting system to the Company’s existing system. (c) Represents net deferred tax assets resulting from the fair value adjustments related to the acquired assets and liabilities, identifiable intangibles, and other purchase accounting adjustments. (d) The adjustment consists of a $0.8 million write-off of capitalized loan costs due to no future economic benefits, a $117 thousand write-off of equipment held for sale due to an estimated zero resale value, and a $75 thousand swap termination fee for prepayment of Firestone’s borrowings. (e) The adjustment is a write-off of a deferred rent accrual. The method to determine the fair value of the loans acquired from Firestone was consistent with the method used in the Hampden acquisition. Accordingly, there was no carryover of Firestone’s allowance for credit losses associated with the loans that were acquired as the loans were initially recorded at fair value. Information about the Firestone acquired loan portfolio subject to ASC 310-30 as of August 6, 2015 is, as follows (in thousands): ASC 310-30 Loans Gross contractual receivable amounts at acquisition $ 5,369 Contractual cash flows not expected to be collected (nonaccretable discount) (3,000 ) Expected cash flows at acquisition 2,369 Interest component of expected cash flows (accretable discount) (827 ) Fair value of acquired loans $ 1,542 The goodwill, which is not amortized for book purposes, was assigned to our banking segment and is not deductible for tax purposes. The Company’s consolidated results of operations include the operating results of Firestone beginning August 7, 2015, the date of acquisition, through the end of the reporting period. For the year ended December 31, 2015, Firestone contributed $8.0 million of net interest income and $2.4 million of net income to the Company’s operating results. Direct acquisition and integration costs of the Firestone acquisition were expensed as incurred, and totaled $1.8 million during the year ended December 31, 2015 and there were none for the same period of 2014. Pro Forma Information (unaudited) The following table presents selected unaudited pro forma financial information reflecting the acquisitions of Hampden and Firestone assuming these acquisitions were completed as of January 1, 2014. The unaudited pro forma financial information includes adjustments for scheduled amortization and accretion of fair value adjustments recorded at the time of the acquisitions. These adjustments would have been different if they had been recorded on January 1, 2014, and they do not include the impact of prepayments. The unaudited pro forma financial information is presented for illustrative purposes only and is not necessarily indicative of the combined financial results of the Company, Hampden, and Firestone had the transaction actually been completed at the beginning of the periods presented, nor does it indicate future results for any other interim or full-year period. Pro forma basic and diluted earnings per common share were calculated using Berkshire’s actual weighted-average shares outstanding for the periods presented plus the 5.63 million shares issued as a result of Hampden and Firestone acquisitions. The unaudited pro forma information is based on the actual financial statements of Berkshire, Hampden, and Firestone for the periods shown until the dates of acquisitions, at which time the Hampden and Firestone operations became included in Berkshire’s financial statements. The unaudited pro forma information, for the years ended December 31, 2015 and 2014, set forth below reflects adjustments related to (a) amortization and accretion of purchase accounting fair value adjustments; (b) amortization of core deposit intangible; and (c) an estimated tax rate of 40.3 percent . Direct acquisition expenses incurred by Berkshire during 2015 as noted above, and $7.7 million and $1.5 million recorded by Hampden and Firestone, respectively, are reversed for the purposes of this unaudited pro forma information. Also excluded during 2015, was a $2.2 million gain on Hampden stock that was held by the Company at the time of acquisition. Furthermore, except for revenue-enhancing and cost savings reflected in the Company’s consolidated results of operations after acquisitions dates, revenue enhancing, operating cost savings, and other business synergies expected as a result of the acquisitions are not reflected in the unaudited pro forma information. Information in the following table is shown in thousands, except earnings per share: Pro Forma (unaudited) 2015 2014 Net interest income $ 230,050 $ 217,409 Non-interest income 53,738 51,743 Net income 57,768 44,052 Pro forma earnings per share: Basic $ 1.90 $ 1.45 Diluted $ 1.89 $ 1.45

Furthermore, the Company does not intend to sell nor does it anticipate that it will be required to sell any of its securities in an unrealized loss position as of December 31, 2015, prior to this recovery. The Company’s ability and intent to hold these securities until recovery is supported by the Company’s strong capital and liquidity positions as well as its historical low portfolio turnover. The following summarizes, by investment security type, the basis for the conclusion that the debt securities in an unrealized loss position within the Company’s AFS and HTM portfolios were not other-than-temporarily impaired at year-end 2015: AFS municipal bonds and obligations At year-end 2015, 6 of the 121 securities in the Company’s portfolio of AFS municipal bonds and obligations were in unrealized loss positions. Aggregate unrealized losses represented 2.4% of the amortized cost of securities in unrealized loss positions. The Company continually monitors the municipal bond sector of the market carefully and periodically evaluates the appropriate level of exposure to the market. At this time, the Company feels that the bonds in this portfolio carry minimal risk of default and that the Company is appropriately compensated for that risk. The bonds are investment grade rated, and there were no material underlying credit downgrades during 2015. All securities are performing. AFS residential mortgage-backed securities At year-end 2015, 117 out of a total of 256 securities in the Company’s portfolio of AFS residential mortgage-backed securities were in unrealized loss positions. Aggregate unrealized losses represented 1.3% of the amortized cost of securities in unrealized loss positions. The Federal National Mortgage Association (“FNMA”), Federal Home Loan Mortgage Corporation (“FHLMC”), and Government National Mortgage Association (“GNMA”) guarantees the contractual cash flows of the Company’s residential mortgage-backed securities. The securities are investment grade rated and there were no material underlying credit downgrades during 2015. All securities are performing. AFS corporate bonds At year-end 2015, 4 out of 7 securities in the Company’s portfolio of AFS corporate bonds were in an unrealized loss position. The aggregate unrealized loss represents 6.0% of the amortized cost of bonds in unrealized loss positions. The Company reviews the financial strength of these bonds and concluded that the amortized cost remains supported by the expected future cash flows of these securities. At year-end 2015, $1.6 million of the total unrealized losses were attributable to a $17.6 million investment. The Company evaluated these securities, with a Level 2 fair value of $16.0 million , for potential other-than-temporary impairment (“OTTI”) at December 31, 2015 and determined that OTTI was not evident based on both the Company’s ability and intent to hold the security until the recovery of its remaining amortized cost. AFS trust preferred securities At year-end 2015, 1 out of the 3 securities in the Company’s portfolio of AFS trust preferred securities was in an unrealized loss position. Aggregate unrealized losses represented 0.2% of the amortized cost of the security in an unrealized loss position. The Company’s evaluation of the present value of expected cash flows on this security supports its conclusions about the recoverability of the securities’ amortized cost basis. This security is investment grade rated. The Company reviews the financial strength of all of the single issue trust issuers and has concluded that the amortized cost remains supported by the market value of these securities and they are performing. AFS other bonds and obligations At year-end 2015, 6 of the 8 securities in the Company’s portfolio of other bonds and obligations were in unrealized loss positions. Aggregate unrealized losses represented 1.1% of the amortized cost of securities in unrealized loss positions. The securities are all investment grade rated, and there were no material underlying credit downgrades during 2015. All securities are performing. HTM Municipal bonds and obligations At year-end 2015, 3 of the 100 securities in the Company’s portfolio of other bonds and obligations were in unrealized loss positions. Aggregate unrealized losses represented 1.6% of the amortized cost of securities in unrealized loss positions. The securities are investment grade rated and there were no material underlying credit downgrades during the quarter. All securities are performing. Marketable Equity Securities In evaluating its marketable equity securities portfolio for OTTI, the Company considers its ability to more likely than not hold an equity security to recovery. The Company additionally considers other various factors including the length of time and the extent to which the fair value has been less than cost and the financial condition and near term prospects of the issuer. Any OTTI is recognized immediately through earnings. At year-end 2015, 9 out of a total of 24 securities in the Company’s portfolio of marketable equity securities were in an unrealized loss position. The unrealized loss represented 17.5% of the amortized cost of the securities. The Company has the ability and intent to hold the securities until a recovery of their cost basis and does not consider the securities other-than-temporarily impaired at year-end 2015. As new information becomes available in future periods, changes to the Company’s assumptions may be warranted and could lead to a different conclusion regarding the OTTI of these securities.

Receivables [Abstract]
LOANS	LOANS The Company’s loan portfolio is segregated into the following segments: residential mortgage, commercial real estate, commercial and industrial, and consumer. Residential mortgage loans include classes for 1-4 family owner occupied and construction loans. Commercial real estate loans include construction, single and multi-family, and other commercial real estate classes. Commercial and industrial loans include asset based lending loans, lease financing and other commercial business loan classes. Consumer loans include home equity, direct and indirect auto and other consumer loan classes. These portfolio segments each have unique risk characteristics that are considered when determining the appropriate level for the allowance for loan losses. A substantial portion of the loan portfolio is secured by real estate in western Massachusetts, southern Vermont, northeastern New York, and in the Bank’s other New England lending areas. The ability of many of the Bank’s borrowers to honor their contracts is dependent, among other things, on the specific economy and real estate markets of these areas. Total loans include business activity loans and acquired loans. Acquired loans are those loans acquired from Firestone Financial Corp., Hampden Bancorp, Inc., the New York branch acquisition, Beacon Federal Bancorp, Inc., The Connecticut Bank and Trust Company, Legacy Bancorp, Inc., and Rome Bancorp, Inc. The following is a summary of total loans: 2015 2014 (In thousands) Business Activities Acquired Loans Total Business Activities Acquired Loans Total Residential mortgages: 1-4 family $ 1,454,233 $ 332,747 $ 1,786,980 $ 1,199,408 $ 268,734 $ 1,468,142 Construction 26,704 1,351 28,055 27,044 1,018 28,062 Total residential mortgages 1,480,937 334,098 1,815,035 1,226,452 269,752 1,496,204 Commercial real estate: Construction 210,196 43,474 253,670 169,189 4,201 173,390 Single and multi-family 214,823 36,783 251,606 140,050 53,168 193,218 Commercial real estate 1,209,008 345,483 1,554,491 1,030,837 214,122 1,244,959 Total commercial real estate 1,634,027 425,740 2,059,767 1,340,076 271,491 1,611,567 Commercial and industrial loans: Asset based lending 331,253 — 331,253 341,246 — 341,246 Other commercial and industrial loans 495,979 221,031 717,010 411,945 51,175 463,120 Total commercial and industrial loans 827,232 221,031 1,048,263 753,191 51,175 804,366 Total commercial loans 2,461,259 646,771 3,108,030 2,093,267 322,666 2,415,933 Consumer loans: Home equity 307,159 53,446 360,605 252,681 65,951 318,632 Auto and other 311,328 130,238 441,566 346,480 103,351 449,831 Total consumer loans 618,487 183,684 802,171 599,161 169,302 768,463 Total loans $ 4,560,683 $ 1,164,553 $ 5,725,236 $ 3,918,880 $ 761,720 $ 4,680,600 Total unamortized net costs and premiums included in the year-end total loans for business activity loans were the following: (In thousands) 2015 2014 Unamortized net loan origination costs $ 17,448 $ 14,268 Unamortized net premium on purchased loans 4,694 4,604 Total unamortized net costs and premiums $ 22,142 $ 18,872 The Company occasionally transfers a portion of its originated commercial loans to participating lending partners. The amounts transferred have been accounted for as sales and are therefore not included in the Company’s accompanying consolidated balance sheets. The Company and its lending partners share proportionally in any gains or losses that may result from a borrower’s lack of compliance with contractual terms of the loan. The Company continues to service the loans, collects cash payments from the borrowers, remits payments (net of servicing fees), and disburses required escrow funds to relevant parties. At year-end 2015 and 2014, the Company was servicing loans for participants totaling $189.0 million and $95.4 million , respectively. In 2015, the Company purchased loans aggregating $124.4 million and sold loans aggregating $121.0 million . In 2014, the Company purchased loans aggregating $50.2 million and sold loans aggregating $290.1 million . Net gains (losses) on sales of loans were $6 million , $4 million , and ($1) million for the years 2015, 2014, and 2013, respectively. These amounts are included in Loan Related Income on the Consolidated Statement of Income. Most of the Company’s lending activity occurs within its primary markets in Western Massachusetts, Southern Vermont, and Northeastern New York. Most of the loan portfolio is secured by real estate, including residential mortgages, commercial mortgages, and home equity loans. Year-end loans to operators of non-residential buildings totaled $842.8 million , or 14.7% , and $691.3 million , or 14.8% of total loans in 2015 and 2014, respectively. There were no other concentrations of loans related to any one industry in excess of 10% of total loans at year-end 2015 or 2014. At year-end 2015, the Company had pledged loans totaling $100 million to the Federal Reserve Bank of Boston as collateral for certain borrowing arrangements. Also, residential first mortgage loans are subject to a blanket lien for FHLBB advances. See Note 12 - Borrowings & Subordinated Notes. At year-end 2015 and 2014, the Company’s commitments outstanding to related parties totaled $3.5 million and $3.3 million , respectively, and the loans outstanding against these commitments totaled $2.1 million and $2.0 million , respectively. Related parties include directors and executive officers of the Company and its subsidiaries and their respective affiliates in which they have a controlling interest, and immediate family members. For the years 2015 and 2014, all related party loans were performing. The carrying amount of the acquired loans at December 31, 2015 totaled $1.2 billion . A subset of these loans was determined to have evidence of credit deterioration at acquisition date, which is accounted for in accordance with ASC 310-30. These purchased credit-impaired loans presently maintain a carrying value of $21.4 million . These loans are evaluated for impairment through the periodic reforecasting of expected cash flows. Of the $21.4 million , $2.6 million are Residential Mortgages, $15.8 million are Commercial Real Estate, $2.8 million are Commercial and Industrial loans, and $249 thousand are Consumer loans. The carrying amount of the acquired loans at December 31, 2014 totaled $762 million . A subset of these loans was determined to have evidence of credit deterioration at acquisition date, which is accounted for in accordance with ASC 310-30. These purchased credit-impaired loans presently maintain a carrying value of $13.8 million . These loans are evaluated for impairment through the periodic reforecasting of expected cash flows. Of the $13.8 million , $375 thousand are Residential Mortgages, $12.3 million are Commercial Real Estate, $986 thousand are Commercial and Industrial loans, and $171 thousand are Consumer loans.

Troubled Debt Restructuring Loans The Company’s loan portfolio also includes certain loans that have been modified in a Troubled Debt Restructuring (TDR), where economic concessions have been granted to borrowers who have experienced or are expected to experience financial difficulties. These concessions typically result from the Company’s loss mitigation activities and could include reductions in the interest rate, payment extensions, forgiveness of principal, forbearance, or other actions. Certain TDRs are classified as nonperforming at the time of restructure and may only be returned to performing status after considering the borrower’s sustained repayment performance for a reasonable period, generally six months . TDRs are evaluated individually for impairment and may result in a specific allowance amount allocated to an individual loan. The following tables include the recorded investment and number of modifications for modified loans identified during the years-ended December 31, 2015, 2014, and 2013 respectively. The tables include the recorded investment in the loans prior to a modification and also the recorded investment in the loans after the loans were restructured. The modifications for the year-ended December 31, 2015 were attributable to interest rate concessions, maturity date extensions, modified payment terms, reamortization, and accelerated maturity. The modifications for the year-ended December 31, 2014 were attributable to interest rate concessions, debt consolidations, and changes to payment terms. The modifications for the year-ended December 31, 2013 were attributable to interest rate concessions, debt consolidations, and maturity date extensions.

(2) Other reductions classification consists of transfer to other real estate owned, charge-offs to loans, and other loan sale payoffs. The evaluation of certain loans individually for specific impairment includes loans that were previously classified as TDRs or continue to be classified as TDRs.

Loans that are given a Pass rating are not considered a problem credit. Loans that are classified as Special Mention loans are considered to have potential weaknesses and are evaluated closely by management. Substandard and non-accruing loans are loans for which a definitive weakness has been identified and which may make full collection of contractual cash flows questionable. Doubtful loans are those with identified weaknesses that make full collection of contractual cash flows, on the basis of currently existing facts, conditions, and values, highly questionable and improbable. For commercial credits, the Company assigns an internal risk rating at origination and reviews the rating annual, semiannually, or quarterly depending on the risk rating. The rating is also reassessed at any point in time when management becomes aware of information that may affect the borrower’s ability to fulfill their obligations. The Company risk rates its residential mortgages, including 1-4 family and residential construction loans, based on a three rating system: Pass, Special Mention, and Substandard. Loans that are current within 59 days are rated Pass. Residential mortgages that are 60 - 89 days delinquent are rated Special Mention. Loans delinquent for 90 days or greater are rated Substandard and generally placed on non-accrual status. Home equity loans are risk rated based on the same rating system as the Company’s residential mortgages. Ratings for other consumer loans, including auto loans, are based on a two rating system. Loans that are current within 119 days are rated Performing while loans delinquent for 120 days or more are rated Non-performing. Other consumer loans are placed on non-accrual at such time as they become Non-performing. Acquired Loans Credit Quality Analysis Upon acquiring a loan portfolio, our internal loan review function assigns risk ratings to the acquired loans, utilizing the same methodology as it does with business activities loans. This may differ from the risk rating policy of the predecessor bank. Loans which are rated Substandard or worse according to the rating process outlined below are deemed to be credit impaired loans accounted for under ASC 310-30, regardless of whether they are classified as performing or non-performing. The Bank utilizes a loan risk rating system for acquired loans consistent with loans originated from business activities, as outlined in the Credit Quality Information section of this Note. The ratings system is similar to loans originated through business activities. The Company subjects loans that do not meet the ASC 310-30 criteria to ASC 450-20 by collectively evaluating these loans for an allowance for loan loss. The Company applies a methodology similar to the methodology prescribed for business activities loans, which includes the application of environmental factors to each category of loans. The methodology to collectively evaluate the acquired loans outside the scope of ASC 310-30 includes the application of a number of environmental factors that reflect management’s best estimate of the level of incremental credit losses that might be recognized given current conditions. This is reviewed as part of the allowance for loan loss adequacy analysis. As the loan portfolio matures and environmental factors change, the loan portfolio will be reassessed each quarter to determine an appropriate reserve allowance. Additionally, the Company considers the need for an additional reserve for acquired loans accounted for outside of the scope of ASC 310-30 under ASC 310-20. At acquisition date, the Bank determined a fair value mark with credit and interest rate components. Under the Company’s model, the impairment evaluation process involves comparing the carrying value of acquired loans, including the entire unamortized premium or discount, to the recorded reserve allowance. If necessary, the Company books an additional reserve to account for shortfalls identified through this calculation. Fair value marks are not bifurcated when evaluating for impairment. A decrease in the expected cash flows in subsequent periods requires the establishment of an allowance for loan losses at that time for ASC 310-30 loans. At year-end 2015, the allowance for loan losses related to acquired loans under ASC 310-30 and ASC 310-20 was $4.7 million using the above mentioned criteria. The Company presented several tables within this footnote separately for business activity loans and acquired loans in order to distinguish the credit performance of the acquired loans from the business activity loans.

The Company holds 100% of the common stock of Berkshire Hills Capital Trust I (“Trust I”) which is included in other assets with a cost of $0.5 million . The sole asset of Trust I is $15.5 million of the Company’s junior subordinated debentures due in 2035. These debentures bear interest at a variable rate equal to LIBOR plus 1.85% and had a rate of 2.18% and 2.08% at December 31, 2015 and December 31, 2014, respectively. The Company has the right to defer payments of interest for up to five years on the debentures at any time, or from time to time, with certain limitations, including a restriction on the payment of dividends to stockholders while such interest payments on the debentures have been deferred. The Company has not exercised this right to defer payments. The Company has the right to redeem the debentures at par value. Trust I is considered a variable interest entity for which the Company is not the primary beneficiary. Accordingly, Trust I is not consolidated into the Company’s financial statements.

Compensation and Retirement Disclosure [Abstract]
EMPLOYEE BENEFIT PLANS	EMPLOYEE BENEFIT PLANS Pension Plans The Company maintains a legacy, employer-sponsored defined benefit pension plan (the “Plan”) for which participation and benefit accruals were frozen on January 1, 2003. The Plan was assumed in connection with the Rome Bancorp acquisition in 2011. Accordingly, no employees are permitted to commence participation in the Plan and future salary increases and years of credited service are not considered when computing an employee’s benefits under the Plan. As of December 31, 2015, all minimum Employee Retirement Income Security Act (“ERISA”) funding requirements have been met. Information regarding the pension plan at December 31, 2015 and 2014 is as follows: (In thousands) 2015 2014 Change in projected benefit obligation: Projected benefit obligation at beginning of year $ 7,193 $ 5,666 Interest cost 268 271 Actuarial (loss)/gain (454 ) 1,607 Benefits paid (351 ) (334 ) Settlements (71 ) (17 ) Projected benefit obligation at end of year 6,585 7,193 Accumulated benefit obligation 6,585 7,193 Change in fair value of plan assets: Fair value of plan assets at plan beginning of year 5,756 5,520 Actual return on plan assets (123 ) 331 Contributions by employer — 256 Benefits paid (351 ) (334 ) Settlements (71 ) (17 ) Fair value of plan assets at end of year 5,211 5,756 Underfunded status $ 1,374 $ 1,437 Amounts Recognized in Consolidated Balance Sheet Other Liabilities $ 1,374 $ 1,437 Net periodic pension cost is comprised of the following for the years ended December 31, 2015 and 2014: (In thousands) 2015 2014 Interest Cost $ 268 $ 271 Expected return on plan assets (455 ) (437 ) Amortization of unrecognized actuarial loss 175 — Net periodic pension costs $ (12 ) $ (166 ) Changes in plan assets and benefit obligations recognized in accumulated other comprehensive income during 2015 and 2014 are as follows: (In thousands) 2015 2014 Amortization of actuarial (loss) $ (176 ) $ — Actuarial loss (gain) 125 1,713 Total loss (gain) recognized in accumulated other comprehensive income (51 ) 1,713 Total loss (gain) recognized in net periodic pension cost recognized and other comprehensive income $ (63 ) $ 1,547 The amounts in accumulated other comprehensive income that have not yet been recognized as components of net periodic benefit cost are a net loss of $2.0 million and $2.0 million in 2015 and 2014, respectively. The Company expects to make cash contributions of $262 thousand to the pension trust during the 2016 fiscal year. The amount expected to be amortized from other comprehensive income into net periodic pension cost over the next fiscal year is $164 thousand . The principal actuarial assumptions used at December 31, 2015 and 2014 were as follows: 2015 2014 Projected benefit obligation Discount rate 4.170 % 3.820 % Net periodic pension cost Discount rate 3.820 % 4.950 % Long term rate of return on plan assets 8.000 % 8.000 % The discount rate that is used in the measurement of the pension obligation is determined by comparing the expected future retirement payment cash flows of the pension plan to the Citigroup Above Median Double-A Curve as of the measurement date. The expected long-term rate of return on Plan assets reflects long-term earnings expectations on existing Plan assets and those contributions expected to be received during the current plan year. In estimating that rate, appropriate consideration was given to historical returns earned by Plan assets in the fund and the rates of return expected to be available for reinvestment. The rates of return were adjusted to reflect current capital market assumptions and changes in investment allocations. The Company’s overall investment strategy with respect to the Plan’s assets is primarily for preservation of capital and to provide regular dividend and interest payments. The Plan’s targeted asset allocation is 65% equity securities via investment in the Long-Term Growth - Equity Portfolio (‘LTGE’), 34% intermediate-term investment grade bonds via investment in the Long-Term Growth - Fixed-Income Portfolio (‘LTGFI’), and 1% in cash equivalents portfolio (for liquidity). Equity securities include investments in a diverse mix of equity funds to gain exposure in the US and international markets. The fixed income portion of the Plan assets is a diversified portfolio that primarily invests in intermediate-term bond funds. The overall rate of return is based on the historical performance of the assets applied against the Plan’s target allocation, and is adjusted for the long-term inflation rate. The fair values for investment securities are determined by quoted prices in active markets, if available (Level 1). For securities where quoted prices are not available, fair values are calculated based on market prices of similar securities (Level 2). For securities where quoted prices or market prices of similar securities are not available, fair values are calculated using discounted cash flows or other market indicators (Level 3). The fair values of the Plan’s assets by category and level within the fair value hierarchy are as follows at December 31, 2015: Asset Category (In thousands) Total Level 1 Level 2 Equity Mutual Funds: Large-Cap $ 1,516 $ — $ 1,516 Mid-Cap 374 — 374 Small-Cap 362 — 362 International 760 — 760 Fixed Income Funds Fixed Income - US Core 1,564 — 1,564 Intermediate Duration 522 — 522 Cash Equivalents - money market 113 62 51 Total $ 5,211 $ 62 $ 5,149 The fair values of the Plan’s assets by category and level within the fair value hierarchy are as follows at December 31, 2014: Asset Category (In thousands) Total Level 1 Level 2 Equity Mutual Funds: Large-Cap $ 1,847 $ — $ 1,847 Small-Cap 488 — 488 International 461 — 461 Equity Trusts 926 — 926 Large-Cap Fixed Income Trusts 1,822 — 1,822 Fixed Income Mutual Funds 212 99 113 Total $ 5,756 $ 99 $ 5,657 The Plan did not hold any assets classified as Level 3, and there were no transfers between levels during 2015 or 2014. Estimated benefit payments under the Company’s pension plans over the next ten years at December 31, 2015 are as follows: Year Payments (In thousands) 2016 363 2017 364 2018 363 2019 409 2020 400 2021-2025 2,004 Postretirement Benefits The Company has an unfunded post-retirement medical plan which was assumed in connection with the Rome Bancorp acquisition in 2011. The postretirement plan has been modified so that participation is closed to those employees who did not meet the retirement eligibility requirements by March 31, 2011. The Company contributes partially to medical benefits and life insurance coverage for retirees. Such retirees and their surviving spouses are responsible for the remainder of the medical benefits, including increases in premiums levels, between the total premium and the Company’s contribution. The Company also has an executive long-term care (“LTC”) postretirement benefit plan which started August 1, 2014. The LTC plan reimburses executives for certain costs in the event of a future chronic illness. Funding of the plan comes from Company paid insurance policies or direct payments. At plan’s inception, a $558 thousand benefit obligation was recorded against equity representing the prior service cost of plan participants. Information regarding the post-retirement plan at December 31, 2015 and 2014 is as follows: (In thousands) 2015 2014 Change in accumulated postretirement benefit obligation: Accumulated post-retirement benefit obligation at beginning of year $ 1,604 $ 996 Prior service cost of long-term care plan participants 1,595 558 Service Cost 34 12 Interest cost 124 48 Participant contributions 47 44 Actuarial loss/ (gain) (284 ) 26 Benefits paid (81 ) (80 ) Amendments — — Accumulated post-retirement benefit obligation at end of year $ 3,039 $ 1,604 Change in plan assets: Fair value of plan assets at beginning of year $ — $ — Contributions by employer 34 36 Contributions by participant 47 44 Benefits paid (81 ) (80 ) Fair value of plan assets at end of year $ — $ — Amounts Recognized in Consolidated Balance Sheet Other Liabilities $ 3,039 $ 1,604 Net periodic post-retirement cost is comprised of the following for the year ended December 31, 2015 and 2014: (In thousands) 2015 2014 Service cost $ 34 $ 12 Interest costs 124 48 Amortization of net prior service credit 83 (11 ) Amortization of net actuarial loss — — Net periodic post-retirement costs $ 241 $ 49 Changes in benefit obligations recognized in accumulated other comprehensive income during 2015 and 2014 are as follows: (In thousands) 2015 2014 Amortization of actuarial loss $ — $ — Amortization of prior service credit (83 ) 11 Net actuarial (gain) loss (257 ) 27 Total recognized in accumulated other comprehensive income (340 ) 38 Accrued post-retirement liability recognized $ 1,555 $ 1,347 The amounts in accumulated other comprehensive income that have not yet been recognized as components of net periodic benefit cost are as follows: (In thousands) 2015 2014 Net prior service cost (credit) $ 1,742 $ 231 Net actuarial (gain) loss (257 ) 27 Total recognized in accumulated other comprehensive income 1,485 258 The amount expected to be amortized from other comprehensive income into net periodic postretirement cost over the next fiscal year is $83 thousand . The discount rates used in the measurement of the postretirement medical and LTC plan obligations are determined by comparing the expected future retirement payment cash flows of the plans to the Citigroup Above Median Double-A Curve as of the measurement date. The assumed discount rates on a weighted-average basis were 4.15% and 3.75% as of December 31, 2015 and December 31, 2014, respectively. The assumed health care cost trend rate used in measuring the accumulated post-retirement benefit medical obligation is expected to be 8.50% for 2016, and is gradually expected to decrease to 7.24% by 2020. This assumption may have a significant effect on the amounts reported. However, as noted above, increases in premium levels are the financial responsibility of the plan beneficiary. Thus an increase or decrease in 1% of the health care cost trend rates utilized would have had an immaterial effect on the service and interest cost as well as the accumulated post-retirement benefit obligation for the postretirement plan as of December 31, 2015. For participants in the LTC plan covered by insurance policies, no increase in annual premiums is assumed based on the history of the corresponding insurance provider. Estimated benefit payments under the post-retirement benefit plan over the next ten years at December 31, 2015 are as follows: Year Payments (In thousands) 2016 80 2017 83 2018 98 2019 98 2020 97 2021 - 2025 544 401(k) Plan The Company provides a 401(k) Plan in which most employees participate. The Company contributes a non-elective 3% of gross annual wages for each participant, regardless of the participant’s deferral, in addition to a 100% match up to 4% of gross annual wages. The Company’s contributions vest immediately. Expense related to the plan was $3.6 million in 2015, $3.0 million in 2014, and $2.9 million in 2013. Employee Stock Ownership Plan (“ESOP”) As part of the acquisition of Hampden in 2015, along with another merger in 2012 and two during 2011, the Company acquired ESOP plans that were frozen and terminated prior to the completion of those transactions. On the acquisition dates, all amounts in the plans were vested and the loans under the plans were repaid from the sale proceeds of unallocated shares. Other Plans The Company maintains a supplemental executive retirement plan (“SERP”) for a few select executives. Benefits generally commence no earlier than age sixty-two and are payable at the executive’s option, either as an annuity or as a lump sum. Some of these SERPs were assumed in connection with the Beacon acquisition in 2012. In 2015 a SERP was acquired in connection with the Hampden Bank acquisition with accrued liability of $1.4 million at acquisition date and $1.3 million at year-end 2015. At year-end 2015 and 2014, the accrued liability for these SERPs were $6.5 million and $4.6 million , respectively. SERP expense was $752 thousand in 2015, $583 thousand in 2014, and $453 thousand in 2013, and is recognized over the required service period. The Company assumed split-dollar agreements with the acquisition of Hampden Bank in 2015 with an accrued liability of $860 thousand at acquisition date in April 2015 and $1.2 million as of year-end 2015. The Company has endorsement split-dollar life insurance arrangements pertaining to certain current and prior executives. Under these arrangements, the Company purchased policies insuring the lives of the executives, and separately entered into agreements to split the policy benefits with the executive. There are no post-retirement benefits associated with these policies.

Refer to Note 2 for more information about the acquisitions. Deferred tax assets, net of valuation allowances, are expected to be realized through the reversal of existing taxable temporary differences and future taxable income. Valuation Allowances The components of the Company’s valuation allowance on its deferred tax asset, net as of December 31, 2015 and 2014 were, as follows: (in thousands) 2015 2014 State tax basis difference, net of Federal tax benefit (of 35%) (229 ) (229 ) Valuation allowances $ (229 ) $ (229 ) The state tax basis difference, net of Federal tax benefit was also originally recorded in 2012, due to management’s assessment that it is more likely than not that certain deferred tax assets recorded for the difference between the book basis and the state tax basis in certain tax credit limited partnership investments (LPs) will not be realized. Management anticipates that the remaining excess state tax basis will be realized as a capital loss upon disposition, and that it is unlikely that the Company will have capital gains against which to offset such capital losses. The valuation allowances as of December 31, 2015 are subject to change in the future as the Company continues to periodically assess the likelihood of realizing its deferred tax assets. Tax Attributes At December 31, 2015, the Company has $9.4 million of federal US net operating loss carryforwards, $2.1 million of New York State net operating losses, and $13.9 million of Connecticut net operating losses available that were obtained through acquisition, the utilization of which are limited under Internal Revenue Code 382. No deferred tax asset has been recorded on the Connecticut net operating loss since the state of Connecticut does not currently allow a deduction for net operating losses. These net operating losses begin to expire in 2024. The related deferred tax asset is $3.3 million . In addition, the Company has general business tax credit carryforwards of $3.2 million available that expire beginning in 2027, and alternative minimum tax credit carryforwards of $4.1 million with no expiration date. The Company anticipates utilizing these carryforwards prior to their expirations. Unrecognized Tax Benefits On a periodic basis, the Company evaluates its income tax positions based on tax laws and regulations and financial reporting considerations, and records adjustments as appropriate. This evaluation takes into consideration the status of taxing authorities’ current examinations of the Company’s tax returns, recent positions taken by the taxing authorities on similar transactions, if any, and the overall tax environment in relation to uncertain tax positions. The following table presents changes in unrecognized tax benefits for the years ended December 31, 2015, 2014, and 2013: (In thousands) 2015 2014 2013 Unrecognized tax benefits at January 1 $ 553 $ 477 $ 492 Increase in gross amounts of tax positions related to prior years — 55 321 Decrease in gross amounts of tax positions related to prior years — — (150 ) Decrease due to settlement with taxing authority — — (186 ) Increase in gross amounts of tax positions related to current year — 93 — Decrease due to lapse in statute of limitations (246 ) (72 ) — Unrecognized tax benefits at December 31 $ 307 $ 553 $ 477 It is reasonably possible that over the next twelve months the amount of unrecognized tax benefits may change from the reevaluation of uncertain tax positions arising in examinations, in appeals, or in the courts, or from the closure of tax statutes. The Company does not expect any significant changes in unrecognized tax benefits during the next twelve months. All of the Company’s unrecognized tax benefits, if recognized, would be recorded as a component of income tax expense, therefore, affecting the effective tax rate. The Company recognizes interest and penalties, if any, related to the liability for uncertain tax positions as a component in income tax expense. The accrual for interest and penalties was not material in all years. The Company and its subsidiaries file income tax returns in the U.S. federal jurisdiction as well as in various states. In the normal course of business, the Company is subject to U.S. federal, state, and local income tax examinations by tax authorities. With the exception of New York state, the Company is no longer subject to examination for tax years prior to 2012 including any related income tax filings from its recent acquisitions. The Company is currently under audit in the state of New York for tax years 2010-2012.

DERIVATIVE INSTRUMENTS AND HEDG

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES	DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES At year-end 2015, the Company held derivatives with a total notional amount of $1.4 billion . That amount included $300 million in forward starting interest rate swap derivatives that were designated as cash flow hedges for accounting purposes. The Company also had economic hedges and non-hedging derivatives totaling $914.8 million and $36.0 million , respectively, which are not designated as hedges for accounting purposes and are therefore recorded at fair value with changes in fair value recorded directly through earnings. Economic hedges included interest rate swaps totaling $914.8 million , risk participation agreements with dealer banks of $59.0 million , and $44.8 million in forward commitment contracts. As part of the Company’s risk management strategy, the Company enters into interest rate swap agreements to mitigate the interest rate risk inherent in certain of the Company’s assets and liabilities. Interest rate swap agreements involve the risk of dealing with both Bank customers and institutional derivative counterparties and their ability to meet contractual terms. The agreements are entered into with counterparties that meet established credit standards and contain master netting and collateral provisions protecting the at-risk party. The derivatives program is overseen by the Risk Management Committee of the Company’s Board of Directors. Based on adherence to the Company’s credit standards and the presence of the netting and collateral provisions, the Company believes that the credit risk inherent in these contracts was not significant at December 31, 2015. The Company pledged collateral to derivative counterparties in the form of cash totaling $16.1 million and securities with an amortized cost of $24.6 million and a fair value of $24.6 million at year-end 2015. The Company does not typically require its commercial customers to post cash or securities as collateral on its program of back-to-back economic hedges. However certain language is written into the International Swaps Dealers Association, Inc. (“ISDA”) and loan documents where, in default situations, the Bank is allowed to access collateral supporting the loan relationship to recover any losses suffered on the derivative asset or liability. The Company may need to post additional collateral in the future in proportion to potential increases in unrealized loss positions.

Each quarter, the Company assesses the effectiveness of each hedging relationship by comparing the changes in cash flows of the derivative hedging instrument with the changes in cash flows of the designated hedged item or transaction. The ineffective portion of changes in the fair value of the derivatives is recognized directly in earnings. The Company has entered into six forward-starting interest rate swaps contracts with a combined notional value of $300 million as of year-end 2015. The six forward-starting swaps become effective in 2016 having durations of three years. This hedge strategy converts the one month rolling FHLBB borrowings based on the FHLBB’s one month fixed interest rate to fixed interest rates, thereby protecting the Company from floating interest rate variability. Amounts included in the Consolidated Statements of Income and in the other comprehensive income section of the Consolidated Statements of Comprehensive Income (related to interest rate derivatives designated as hedges of cash flows), were as follows: Years Ended December 31, (In thousands) 2015 2014 Interest rate swaps on FHLBB borrowings: Unrealized (loss) recognized in accumulated other comprehensive loss $ (5,232 ) $ (6,405 ) Reclassification of unrealized (loss) from accumulated other comprehensive loss to interest expense — — Reclassification of unrealized loss from accumulated other comprehensive loss to other non-interest expense for termination of swaps — 8,630 Reclassification of unrealized deferred tax (benefit) from accumulated other comprehensive loss to tax expense for terminated swaps — (3,611 ) Net tax benefit on items recognized in accumulated other comprehensive loss 2,094 2,583 Interest rate swaps on junior subordinated notes: Unrealized (loss) recognized in accumulated other comprehensive loss — (1 ) Reclassification of unrealized loss from accumulated other comprehensive loss to interest expense — 204 Net tax expense on items recognized in accumulated other comprehensive loss — (80 ) Other comprehensive income recorded in accumulated other comprehensive loss, net of reclassification adjustments and tax effects $ (3,138 ) $ 1,320 Net interest expense recognized in interest expense on hedged FHLBB borrowings $ — $ — Net interest expense recognized in interest expense on junior subordinated notes $ — $ 204 Hedge ineffectiveness on interest rate swaps designated as cash flow hedges was immaterial to the Company’s financial statements during the year-ended December 31, 2015 and 2014 . Amounts reported in accumulated other comprehensive income related to derivatives will be reclassified to interest expense as interest payments are made on the Company’s variable-rate liabilities. During the next 12 months, the Company anticipates the reclassification of $3.4 million . As a result of the branch acquisition, in the first quarter of 2014, the Company initiated and subsequently terminated all of its interest rate swaps, with various institutions, associated with FHLB advances with 3-month LIBOR based floating interest rates with an aggregate notional amount of $30 million , all of its interest rate swaps associated with 90 day rolling FHLB advances issued using the FHLB’s 3 -month fixed interest rate with an aggregate notional amount of $145 million and all of its forward-starting interest rate swaps associated with 90 day rolling FHLB advances issued using the FHLB’s 3 -month fixed interest rate with an aggregate notional amount of $235 million . In the first quarter of 2014, the Company elected to extinguish $215 million of FHLB advances related to the terminated swaps. As a result the Company reclassified $8.6 million of losses from the effective portion of the unrealized changes in the fair value of the terminated derivatives from other comprehensive income to non-interest income as the forecasted transactions to the related FHLB advances will not occur. Economic hedges As of December 31, 2015 the Company has an interest rate swap with a $12.0 million notional amount to swap out the fixed rate of interest on an economic development bond bearing a fixed rate of 5.09% , currently within the Company’s trading portfolio under the fair value option, in exchange for a LIBOR-based floating rate. The intent of the economic hedge is to improve the Company’s asset sensitivity to changing interest rates in anticipation of favorable average floating rates of interest over the 21 -year life of the bond. The fair value changes of the economic development bond are mostly offset by fair value changes of the related interest rate swap. The Company also offers certain derivative products directly to qualified commercial borrowers. The Company economically hedges derivative transactions executed with commercial borrowers by entering into mirror-image, offsetting derivatives with third-party financial institutions. The transaction allows the Company’s customer to convert a variable-rate loan to a fixed rate loan. Because the Company acts as an intermediary for its customer, changes in the fair value of the underlying derivative contracts mostly offset each other in earnings. Credit valuation adjustments arising from the difference in credit worthiness of the commercial loan and financial institution counterparties totaled $(13.0) thousand at year-end 2015. The interest income and expense on these mirror image swaps exactly offset each other. The Company has risk participation agreements with dealer banks. Risk participation agreements occur when the Company participates on a loan and a swap where another bank is the lead. The Company earns a fee to take on the risk associated with having to make the lead bank whole on Berkshire’s portion of the pro-rated swap should the borrower default. The Company utilizes forward sale commitments to hedge interest rate risk and the associated effects on the fair value of interest rate lock commitments and loans held for sale. The forward sale commitments are accounted for as derivatives with changes in fair value recorded in current period earnings. The company uses the following types of forward sale commitments contracts: • Best efforts loan sales, • Mandatory delivery loan sales, and • To be announced (TBA) mortgage-backed securities sales. A best efforts contract refers to a loan sales agreement where the Company commits to deliver an individual mortgage loan of a specified principal amount and quality to an investor if the loan to the underlying borrower closes. The Company may enter into a best efforts contract once the price is known, which is shortly after the potential borrower’s interest rate is locked. A mandatory delivery contract is a loan sales agreement where the Company commits to deliver a certain principal amount of mortgage loans to an investor at a specified price on or before a specified date. Generally, the Company may enter into mandatory delivery contracts shortly after the loan closes with a customer. The Company may sell to-be-announced mortgage-backed securities to hedge the changes in fair value of interest rate lock commitments and held for sale loans, which do not have corresponding best efforts or mandatory delivery contracts. These security sales transactions are closed once mandatory contracts are written. On the closing date the price of the security is locked-in, and the sale is paired-off with a purchase of the same security. Settlement of the security purchase/sale transaction is done with cash on a net-basis. Non-hedging derivatives The Company enters into interest rate lock commitments (“IRLCs”) for residential mortgage loans, which commit the Company to lend funds to a potential borrower at a specific interest rate and within a specified period of time. IRLCs that relate to the origination of mortgage loans that will be held for sale are considered derivative financial instruments under applicable accounting guidance. Outstanding IRLCs expose the Company to the risk that the price of the mortgage loans underlying the commitments may decline due to increases in mortgage interest rates from inception of the rate lock to the funding of the loan. The IRLCs are free-standing derivatives which are carried at fair value with changes recorded in noninterest income in the Company’s consolidated statements of income. Changes in the fair value of IRLCs subsequent to inception are based on changes in the fair value of the underlying loan resulting from the fulfillment of the commitment and changes in the probability that the loan will fund within the terms of the commitment, which is affected primarily by changes in interest rates and the passage of time. Amounts included in the Consolidated Statements of Income related to economic hedges and non-hedging derivatives were as follows: Years Ended December 31, (In thousands) 2015 2014 Economic hedges Interest rate swap on industrial revenue bond: Unrealized (loss) gain recognized in other non-interest income $ (344 ) $ (1,333 ) Interest rate swaps on loans with commercial loan customers: Unrealized gain recognized in other non-interest income (4,852 ) (4,514 ) Reverse interest rate swaps on loans with commercial loan customers: Unrealized loss recognized in other non-interest income 4,852 4,514 Favorable change in credit valuation adjustment recognized in other non-interest income (51 ) 20 Risk Participation Agreements: Unrealized loss recognized in other non-interest income (36 ) (91 ) Forward Commitments: Unrealized gain (loss) recognized in other non-interest income (247 ) (510 ) Realized (loss) gain in other non-interest income 45 (1,494 ) Non-hedging derivatives Interest rate lock commitments: Unrealized gain recognized in other non-interest income 2,436 625 Realized gain (loss) in other non-interest income $ 1,899 $ 3,938 Assets and Liabilities Subject to Enforceable Master Netting Arrangements Interest Rate Swap Agreements (“Swap Agreements”) The Company enters into swap agreements to facilitate the risk management strategies for commercial banking customers. The Company mitigates this risk by entering into equal and offsetting swap agreements with highly rated third party financial institutions. The swap agreements are free-standing derivatives and are recorded at fair value in the Company’s consolidated statements of condition. The Company is party to master netting arrangements with its financial institution counterparties; however, the Company does not offset assets and liabilities under these arrangements for financial statement presentation purposes. The master netting arrangements provide for a single net settlement of all swap agreements, as well as collateral, in the event of default on, or termination of, any one contract. Collateral generally in the form of marketable securities is received or posted by the counterparty with net liability positions, respectively, in accordance with contract thresholds. The Company had net asset positions with its commercial banking counterparties totaling $17.1 million and $12.3 million as of December 31, 2015 and December 31, 2014, respectively. The Company had net liability positions with its financial institution counterparties totaling $27.5 million and $18.2 million as of December 31, 2015 and December 31, 2014, respectively. At December 31, 2015, the Company did not have a net liability position with its commercial banking counterparties, compared to a $0.1 million liability at December 31, 2014. The collateral posted by the Company that covered liability positions was $27.5 million and $18.2 million as of December 31, 2015 and December 31, 2014, respectively. The following table presents the assets and liabilities subject to an enforceable master netting arrangement as of December 31, 2015 and December 31, 2014 : Offsetting of Financial Assets and Derivative Assets Gross Gross Amounts Net Amounts of Assets Gross Amounts Not Offset in the Statements Financial Cash (in thousands) Net Amount As of December 31, 2015 Interest Rate Swap Agreements: Institutional counterparties $ 40 $ — $ 40 $ — $ — $ 40 Commercial counterparties 17,129 — 17,129 — — 17,129 Total $ 17,169 $ — $ 17,169 $ — $ — $ 17,169 Offsetting of Financial Liabilities and Derivative Liabilities Gross Gross Amounts Net Amounts of Liabilities Gross Amounts Not Offset in the Statements Financial Cash (in thousands) Net Amount As of December 31, 2015 Interest Rate Swap Agreements: Institutional counterparties $ (28,220 ) $ — $ (28,220 ) $ 18,500 $ 9,720 $ — Commercial counterparties — — — — — — Total $ (28,220 ) $ — $ (28,220 ) $ 18,500 $ 9,720 $ — Offsetting of Financial Assets and Derivative Assets Gross Gross Amounts Net Amounts of Assets Gross Amounts Not Offset in the Statements Financial Cash (in thousands) Net Amount As of December 31, 2014 Interest Rate Swap Agreements: Institutional counterparties $ 23 $ — $ 23 $ — $ — $ 23 Commercial counterparties 12,270 — 12,270 — — 12,270 Total $ 12,293 $ — $ 12,293 $ — $ — $ 12,293 Offsetting of Financial Liabilities and Derivative Liabilities Gross Gross Amounts Net Amounts of Liabilities Gross Amounts Not Offset in the Statements Financial Cash (in thousands) Net Amount As of December 31, 2014 Interest Rate Swap Agreements: Institutional counterparties $ (18,232 ) $ 58 $ (18,174 ) $ 14,984 $ 3,190 $ — Commercial counterparties (50 ) — (50 ) — — (50 ) Total $ (18,282 ) $ 58 $ (18,224 ) $ 14,984 $ 3,190 $ (50 )

Commitments and Contingencies Disclosure [Abstract]
OTHER COMMITMENTS, CONTINGENCIES, AND OFF-BALANCE SHEET ACTIVITIES	OTHER COMMITMENTS, CONTINGENCIES, AND OFF-BALANCE SHEET ACTIVITIES Credit Related Financial Instruments. The Company is a 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. Such commitments involve, to varying degrees, elements of credit, and interest rate risk in excess of the amount recognized in the accompanying consolidated balance sheets. The Company’s exposure to credit loss in the event of non-performance by the other party to the financial instrument is represented by the contractual amount of these commitments. The Company uses the same credit policies in making commitments as it does for on-balance-sheet instruments. A summary of financial instruments outstanding whose contract amounts represent credit risk is as follows at year-end: (In thousands) 2015 2014 Commitments to originate new loans $ 102,145 $ 67,817 Unused funds on commercial and other lines of credit 525,603 514,179 Unadvanced funds on home equity lines of credit 258,897 225,731 Unadvanced funds on construction and real estate loans 201,764 183,301 Standby letters of credit 12,775 12,462 Lease obligation 11,939 12,206 Total $ 1,113,123 $ 1,015,696 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. The commitments for lines of credit may expire without being drawn upon. Therefore, the total commitment amounts do not necessarily represent future cash requirements. The Company evaluates each customer’s creditworthiness on a case-by-case basis. Standby letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third party. These letters of credit are primarily issued to support borrowing arrangements. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers. The Company considers standby letters of credit to be guarantees and the amount of the recorded liability related to such guarantees was not material at year-end 2015. Operating Lease Commitments. Future minimum rental payments required under operating leases at year-end 2015 are as follows: 2016 — $7.8 million ; 2017 — $6.4 million ; 2018 — $5.5 million ; 2019 — $4.8 million ; 2020 — $4.3 million ; and all years thereafter — $37.0 million . The leases contain options to extend for periods up to twenty years. The cost of such rental options is not included above. Total rent expense for the years 2015, 2014, and 2013 amounted to $7.5 million , $7.2 million , and $5.7 million , respectively. Lease Obligations. Future obligations required under the capital lease at year-end 2015 are $715 thousand in 2016; $680 thousand in 2017; $647 thousand in 2018; $646 thousand in 2019; $644 thousand in 2020 and $6.2 million all years thereafter. Amortization under the capital lease is included with premises and equipment depreciation and amortization expense. Future obligations required under the financing lease at year-end 2015 are $80 thousand in 2016; $81 thousand in 2017; $86 thousand in 2018; $86 thousand in 2019; $86 thousand in 2020; and $1.7 million all years thereafter. Amortization under the financing lease is included with premises and equipment depreciation and amortization expense. Employment and Change in Control Agreements. The Company and the Bank have entered into a three -year employment agreement with one senior executive. The Company and the Bank also have change in control agreements with several officers which provide a severance payment in the event employment is terminated in conjunction with a defined change in control. Legal Claims. Various legal claims arise from time to time in the normal course of business. In the opinion of management, claims outstanding at year-end 2015 will have no material effect on the Company’s financial statements.

STOCKHOLDERS' EQUITY AND EARNINGS PER COMMON SHARE	STOCKHOLDERS’ EQUITY AND EARNINGS PER COMMON SHARE Minimum Regulatory Capital Requirements The Company and Bank are subject to various regulatory capital requirements administered by the federal and state banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if imposed, could have a direct material impact on the Company’s financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company and Bank must meet specific capital guidelines that involve quantitative measures of its assets, liabilities and certain off-balance-sheet items as calculated under regulatory accounting practices. The capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weighting and other factors. Quantitative measures established by regulation to ensure capital adequacy require the Company and Bank to maintain minimum amounts and ratios (set forth in the following table) of total and Tier 1 capital (as defined in the regulations) to risk-weighted assets (as defined) and of Tier 1 capital to average assets (as defined). As of year-end 2015 and 2014, the Bank and the Company met the capital adequacy requirements. Regulators may set higher expected capital requirements in some cases based on their examinations. As of year-end 2015 and 2014 , the Bank and the Company met the conditions to be classified as “well capitalized” under the regulatory framework for prompt corrective action. To be categorized as well capitalized, an institution must maintain minimum total risk-based, Tier 1 risk-based, and Tier 1 leverage ratios as set forth in the following tables. The Company and Bank’s actual and required capital amounts were as follows: Minimum Capital Requirement Minimum to be Well Capitalized Under Prompt Corrective Action Provisions Actual (Dollars in thousands) Amount Ratio Amount Ratio Amount Ratio December 31, 2015 Company (Consolidated) Total capital to risk-weighted assets $ 686,489 11.91 % $ 461,231 8.00 % $ 576,539 10.00 % Common Equity Tier 1 Capital to risk weighted assets 573,033 9.80 259,443 4.50 374,750 6.50 Tier 1 capital to risk-weighted assets 573,033 9.94 345,924 6.00 461,231 8.00 Tier 1 capital to average assets 573,033 7.71 297,420 4.00 371,775 5.00 Bank Total capital to risk-weighted assets $ 642,866 11.16 % $ 460,882 8.00 % $ 576,103 10.00 % Common Equity Tier 1 Capital to risk weighted assets 569,131 9.88 259,246 4.50 374,467 6.50 Tier 1 capital to risk-weighted assets 569,131 9.88 345,662 6.00 460,882 8.00 Tier 1 capital to average assets 569,131 7.66 297,313 4.00 371,641 5.00 December 31, 2014 Company (Consolidated) Total capital to risk-weighted assets $ 542,608 11.38 % $ 381,463 8.00 % $ 476,829 10.00 % Common Equity Tier 1 Capital to risk weighted assets N/A N/A N/A N/A N/A N/A Tier 1 capital to risk-weighted assets 430,374 9.03 190,731 4.00 286,097 6.00 Tier 1 capital to average assets 430,374 7.01 245,558 4.00 306,947 5.00 Bank Total capital to risk-weighted assets $ 513,368 10.78 % $ 380,959 8.00 % $ 476,199 10.00 % Common Equity Tier 1 Capital to risk weighted assets N/A N/A N/A N/A N/A N/A Tier 1 capital to risk-weighted assets 440,420 9.25 190,479 4.00 285,719 6.00 Tier 1 capital to average assets 440,420 7.18 245,494 4.00 306,867 5.00 A reconciliation of the Company’s year-end total stockholders’ equity to the Company’s regulatory capital is as follows: 2015 2014 Total stockholders’ equity per consolidated financial statements $ 887,189 $ 709,287 Adjustments for Bank Tier 1 Capital: Net unrealized loss (gain) on available for sale securities (4,058 ) (9,916 ) Net unrealized loss on cash flow hedges 5,108 3,338 Net unrealized loss on defined benefit postretirement plan 2,077 — Qualifying restricted core capital elements 15,000 15,000 Disallowed goodwill and other intangible assets (320,120 ) (276,270 ) Disallowed deferred taxes (3,928 ) (11,065 ) Non-significant investments in tier 1 capital of unconsolidated financial institutions (8,235 ) — Total Bank Tier 1 Capital $ 573,033 $ 430,374 Adjustments for total capital: Qualifying subordinated debt 74,348 74,283 Includable allowances for loan losses 39,468 35,722 Net unrealized loss on available for sale securities includable in Tier 2 capital 968 2,229 Non-significant investments in tier 2 capital of unconsolidated financial institutions (1,328 ) — Total Bank capital per regulatory reporting $ 686,489 $ 542,608 A reconciliation of the Company’s year-end total stockholders’ equity to the Bank’s regulatory capital is as follows: (In thousands) 2015 2014 Total stockholders’ equity per consolidated financial statements $ 887,189 $ 709,287 Adjustments for Bank Tier 1 Capital: Holding company equity adjustment (8,386 ) 1,868 Net unrealized loss (gain) on available for sale securities (4,095 ) (9,912 ) Net unrealized loss on cash flow hedges 5,108 1,970 Net unrealized loss on defined benefit postretirement plan 2,077 1,368 Disallowed goodwill and other intangible assets (299,619 ) (251,748 ) Disallowed deferred taxes (9,807 ) (12,413 ) Non-significant investments in tier 1 capital of unconsolidated financial institutions (3,336 ) N/A Total Bank Tier 1 Capital 569,131 440,420 Adjustments for total capital: Qualifying subordinated debt 35,000 35,000 Includable allowances for loan losses 39,468 35,722 Net unrealized loss on available for sale securities includible in Tier 2 capital 970 2,226 Non-significant investments in tier 2 capital of unconsolidated financial institutions (1,703 ) N/A Total Bank capital per regulatory reporting $ 642,866 $ 513,368 Common stock The Bank is subject to dividend restrictions imposed by various regulators, including a limitation on the total of all dividends that the Bank may pay to the Company in any calendar year. The total of all dividends shall not exceed the Bank’s net income for the current year (as defined by statute), plus the Bank’s net income retained for the two previous years, without regulatory approval. Dividends from the Bank are an important source of funds to the Company to make dividend payments on its common and preferred stock, to make payments on its borrowings, and for its other cash needs. The ability of the Company and the Bank to pay dividends is dependent on regulatory policies and regulatory capital requirements. The ability to pay such dividends in the future may be adversely affected by new legislation or regulations, or by changes in regulatory policies relating to capital, safety and soundness, and other regulatory concerns. The payment of dividends by the Company is subject to Delaware law, which generally limits dividends to an amount equal to an excess of the net assets of a company (the amount by which total assets exceed total liabilities) over statutory capital, or if there is no excess, to the Company’s net profits for the current and/or immediately preceding fiscal year.

Basic earnings per common share (“EPS”) excludes dilution and is computed by dividing net income applicable to common stock by the weighted average number of common shares outstanding for the year. Diluted EPS reflects the potential dilution that could occur if securities or other contracts to issue common stock (such as stock options) were exercised or converted into additional common shares that would then share in the earnings of the entity. Diluted EPS is computed by dividing net income applicable to common stock by the weighted average number of common shares outstanding for the year, plus an incremental number of common-equivalent shares computed using the treasury stock method. Earnings per common share has been computed based on the following (average diluted shares outstanding is calculated using the treasury stock method): Years Ended December 31, (In thousands, except per share data) 2015 2014 2013 Net income $ 49,518 $ 33,744 $ 41,143 Average number of common shares issued 30,074 26,525 26,525 Less: average number of treasury shares 1,215 1,386 1,424 Less: average number of unvested stock award shares 466 409 299 Average number of basic common shares outstanding 28,393 24,730 24,802 Plus: dilutive effect of unvested stock award shares 106 67 60 Plus: dilutive effect of stock options outstanding 65 57 103 Average number of diluted common shares outstanding 28,564 24,854 24,965 Basic earning per share $ 1.74 $ 1.36 $ 1.66 Diluted earnings per share $ 1.73 $ 1.36 $ 1.65 For the year ended 2015, 200 thousand options were anti-dilutive and therefore excluded from the earnings per share calculations. For the year ended 2014, 225 thousand options were anti-dilutive and therefore excluded from the earnings per share calculations. For the year ended 2013, 338 thousand options were anti-dilutive and therefore excluded from the earnings per share calculations.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
STOCK-BASED COMPENSATION PLANS	STOCK-BASED COMPENSATION PLANS The 2013 Equity Incentive Plan (the “2013 Plan”) permits the granting of a combination of Restricted Stock awards and incentive and non-qualified stock options (“Stock Options”) to employees and directors. A total of 1.03 million shares was authorized under the Plan. Awards may be granted as either Restricted Stock or Stock Options provided that any shares that are granted as Restricted Stock are counted against the share limit set forth as (1) three for every one share of Restricted Stock granted and (2) one for every one share of Stock Option granted. As of year-end 2015, the Company had the ability to grant approximately 756 thousand shares under this plan. The 2011 Equity Incentive Plan (the “2011 Plan”) permits the granting of a combination of Restricted Stock awards and incentive and non-qualified stock options to employees and directors. A total of 1.4 million shares was authorized under the Plan. Awards may be granted as either Restricted Stock or Stock Options provided that any shares that are granted as Restricted Stock are counted against the share limit set forth as (1) three for every one share of Restricted Stock granted and (2) one for every one share of Stock Option granted. As of year-end 2015, the Company had the ability to grant approximately 5 thousand shares under this plan. A summary of activity in the Company’s stock compensation plans is shown below: Non-vested Stock Stock Options Outstanding (Shares in thousands) Number of Shares Weighted- Average Number of Shares Weighted- Average Exercise Price Balance, December 31, 2014 424 $ 24.33 282 $ 20.72 Granted 226 26.66 — — Stock options exercised — — (16 ) 14.59 Stock awards vested (142 ) 23.83 — — Forfeited (20 ) 24.91 — — Expired — — (1 ) 25.93 Balance, December 31, 2015 488 $ 25.09 265 $ 21.11 Exercisable options, December 31, 2015 265 $ 21.08 Stock Awards The total compensation cost for stock awards recognized as expense was $4.7 million , $3.8 million , and $2.1 million , in the years 2015, 2014, and 2013, respectively. The total recognized tax benefit associated with this compensation cost was $1.9 million , $1.5 million , and $0.9 million , respectively. The weighted average fair value of stock awards granted was $26.66 , $24.60 , and $24.49 in 2015, 2014, and 2013, respectively. Stock awards vest over periods up to five years and are valued at the closing price of the stock on the grant date. The total fair value of stock awards vested during 2015, 2014, and 2013 was $3.4 million , $2.0 million , and $1.9 million respectively. The unrecognized stock-based compensation expense related to unvested stock awards was $7.0 million as of year-end 2015. This amount is expected to be recognized over a weighted average period of two years. Option Awards Option awards are granted with an exercise price equal to the market price of the Company’s stock at the date of grant, and vest over periods up to five years. The options grant the holder the right to acquire a share of the Company’s common stock for each option held, and have a contractual life of ten years. As of year-end 2015, the weighted average remaining contractual term for options outstanding is two years. The Company generally issues shares from treasury stock as options are exercised. The fair value of each option grant is estimated on the date of grant using the Black-Scholes option-pricing model. The expected dividend yield and expected term are based on management estimates. The expected volatility is based on historical volatility. The risk-free interest rates for the expected term are based on the U.S. Treasury yield curve in effect at the time of the grant. The Company acquired options in the Beacon transaction in 2012, but did not grant additional options in 2015, 2014, or 2013. The total intrinsic value of options exercised was $210.0 thousand , $1.2 million , and $2.9 million for the years 2015, 2014, and 2013, respectively. There was no expense pertaining to options vesting in 2015. The expense pertaining to options vesting in the years 2014 and 2013 was $41 thousand and $860 thousand , respectively. There was no tax benefit associated with stock option expense in 2015. The total recognized tax benefit associated with stock option expense for 2014 and 2013 were $16 thousand and $347 thousand , respectively. There was no unrecognized stock-based compensation expense related to unvested stock options as of year-ends 2015 and 2014.

Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS	FAIR VALUE MEASUREMENTS A description of the valuation methodologies used for instruments measured at fair value, as well as the general classification of such instruments pursuant to the valuation hierarchy, is set forth below. These valuation methodologies were applied to all of the Company’s financial assets and financial liabilities that are carried at fair value. Recurring Fair Value Measurements of Financial Instruments The following table summarizes assets and liabilities measured at fair value on a recurring basis as of year-end 2015 and 2014 segregated by the level of the valuation inputs within the fair value hierarchy utilized to measure fair value. December 31, 2015 (In thousands) Level 1 Level 2 Level 3 Total Trading security $ — $ — $ 14,189 $ 14,189 Available-for-sale securities: Municipal bonds and obligations — 104,561 — 104,561 Government guaranteed residential mortgage-backed securities — 69,858 — 69,858 Government-sponsored residential mortgage-backed securities — 890,007 — 890,007 Corporate bonds — 41,022 — 41,022 Trust preferred securities — 11,901 — 11,901 Other bonds and obligations — 3,141 — 3,141 Marketable equity securities 32,925 334 708 33,967 Loans held for sale — 13,191 — 13,191 Derivative assets 45 17,130 332 17,507 Derivative liabilities — 28,181 — 28,181 December 31, 2014 (In thousands) Level 1 Level 2 Level 3 Total Trading security $ — $ — $ 14,909 $ 14,909 Available-for-sale securities: Municipal bonds and obligations — 133,699 — 133,699 Government guaranteed residential mortgage-backed securities — 69,468 — 69,468 Government-sponsored residential mortgage-backed securities — 760,184 — 760,184 Corporate bonds — 54,151 — 54,151 Trust preferred securities — 14,667 1,548 16,215 Other bonds and obligations — 3,159 — 3,159 Marketable equity securities 53,806 358 778 54,942 Loans held for sale — 19,493 — 19,493 Derivative assets — 12,328 625 12,953 Derivative liabilities 417 18,259 93 18,769 There were no transfers between Level 1, 2, and 3 during the years ended December 31, 2015 and 2014. Trading Security at Fair Value. The Company holds one security designated as a trading security. It is a tax advantaged economic development bond issued to the Company by a local nonprofit which provides wellness and health programs. The determination of the fair value for this security is determined based on a discounted cash flow methodology. Certain inputs to the fair value calculation are unobservable and there is little to no market activity in the security; therefore, the security meets the definition of a Level 3 security. The discount rate used in the valuation of the security is sensitive to movements in the 3-month LIBOR rate. Securities Available for Sale . AFS securities classified as Level 1 consist of publicly-traded equity securities for which the fair values can be obtained through quoted market prices in active exchange markets. AFS securities classified as Level 2 include most of the Company’s debt securities. The pricing on Level 2 was primarily sourced from third party pricing services, overseen by management, and is based on models that consider standard input factors such as dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, live trading levels, trade execution data, market consensus prepayment speeds, credit information and the bond’s terms and condition, among other things. The Company owns one privately owned equity security classified as Level 3. The security’s fair value is determined through unobservable issuer-provided financial information and a pricing model utilizing peer data. Loans held for sale. The Company elected the fair value option for all loans originated for sale (HFS) that were originated for sale on or after May 1, 2012. Loans HFS are classified as Level 2 as the fair value is based on input factors such as quoted prices for similar loans in active markets. Aggregate Aggregate Aggregate Fair Value December 31, 2015 (In thousands) Loans Held for Sale $ 13,191 $ 12,914 $ 277 Aggregate Aggregate Aggregate Fair Value December 31, 2014 (In thousands) Loans Held for Sale $ 19,493 $ 18,885 $ 608 The changes in fair value of loans held for sale for years ended December 31, 2015 and 2014 were gains of $331 thousand and losses of $409 thousand , respectively. The changes in fair value are included in mortgage banking income in the Consolidated Statements of Income. Derivative Assets and Liabilities. Interest Rate Swap. The valuation of the Company’s interest rate swaps is obtained from a third-party pricing service and is determined using a discounted cash flow analysis on the expected cash flows of each derivative. The pricing analysis is based on observable inputs for the contractual terms of the derivatives, including the period to maturity and interest rate curves. The Company incorporates credit valuation adjustments to appropriately reflect both its own nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements. In adjusting the fair value of its derivative contracts for the effect of nonperformance risk, the Company has considered the impact of netting and any applicable credit enhancements, such as collateral postings. Although the Company has determined that the majority of the inputs used to value its interest rate derivatives fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with its derivatives utilize Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default by itself and its counterparties. However, as of year-end 2015, the Company has assessed the significance of the impact of the credit valuation adjustments on the overall valuation of its derivative positions and has determined that the credit valuation adjustments are not significant to the overall valuation of its derivatives. As a result, the Company has determined that its derivative valuations in their entirety are classified in Level 2 of the fair value hierarchy. Interest Rate Lock Commitments. The Company enters into IRLCs for residential mortgage loans intended for sale, which commit the Company to lend funds to a potential borrower at a specific interest rate and within a specified period of time. The estimated fair value of commitments to originate residential mortgage loans for sale is based on quoted prices for similar loans in active markets. However, this value is adjusted by a factor which considers the likelihood that the loan in a lock position will ultimately close, and by the non-refundable costs of originating the loan. The closing ratio is derived from the Bank’s internal data and is adjusted using significant management judgment. The costs to originate are primarily based on the Company’s internal commission rates that are not observable. As such, IRLCs are classified as Level 3 measurements. Forward Sale Commitments . The Company utilizes forward sale commitments as economic hedges against potential changes in the values of the IRLCs and loans originated for sale. To be announced (TBA) mortgage-backed securities forward commitment sales are used as hedging instruments, are classified as Level 1, and consist of publicly-traded debt securities for which identical fair values can be obtained through quoted market prices in active exchange markets. The fair values of the Company’s best efforts and mandatory delivery loan sale commitments are determined similarly to the IRLCs using quoted prices in the market place that are observable. However, costs to originate and closing ratios included in the calculation are internally generated and are based on management’s judgment and prior experience, which are considered factors that are not observable. As such, best efforts and mandatory forward sale commitments are classified as Level 3 measurements. The table below presents the changes in Level 3 assets that were measured at fair value on a recurring basis at year-end 2015 and 2014 : Assets (Liabilities) (In thousands) Trading Securities Interest Rate Forward Balance as of December 31, 2013 $ 14,840 $ 1,964 $ 258 $ 19 Purchase of marketable equity security — — — — Unrealized (loss) gain, net recognized in other non-interest income 610 — 3,804 (112 ) Unrealized gain included in accumulated other comprehensive loss — 362 — — Paydown of trading security (541 ) — — — Transfers to held for sale loans — — (3,437 ) — Balance as of December 31, 2014 $ 14,909 $ 2,326 $ 625 $ (93 ) Purchase of marketable equity security — — — — Sale of AFS Security — (1,327 ) — — Unrealized (loss) gain, net recognized in other non-interest income (150 ) — 4,364 102 Unrealized gain included in accumulated other comprehensive loss — (291 ) — — Paydown of trading security (570 ) — — — Transfers to held for sale loans — — (4,666 ) — Balance as of December 31, 2015 $ 14,189 $ 708 $ 323 $ 9 Unrealized gains (losses) relating to instruments still held at December 31, 2015 $ 2,204 $ (61 ) $ 323 $ 9 Unrealized gains (losses) relating to instruments still held at December 31, 2014 $ 2,355 $ (999 ) $ 625 $ (93 ) Quantitative information about the significant unobservable inputs within Level 3 recurring assets/(liabilities) as of December 31, 2015 and 2014 are as follows: Fair Value Significant (In thousands) December 31, 2015 Valuation Techniques Unobservable Inputs Assets Trading Security $ 14,189 Discounted Cash Flow Discount Rate 2.49 % Securities Available for Sale 708 Pricing Model Median Peer Price/ Tangible Book Value Percentage Multiple 88.52 % Forward Commitments 9 Historical Trend Closing Ratio 92.57 % Pricing Model Origination Costs, per loan $ 2,500 Interest Rate Lock Commitment 323 Historical Trend Closing Ratio 92.57 % Pricing Model Origination Costs, per loan $ 2,500 Total $ 15,229 Fair Value Significant (In thousands) December 31, 2014 Valuation Techniques Unobservable Inputs Assets Trading Security $ 14,909 Discounted Cash Flow Discount Rate 2.60 % Securities Available for Sale 2,326 Discounted Cash Flow Discount Rate 13.74% Forward Commitments (93 ) Historical Trend Closing Ratios 91.07% Pricing Model Origination Costs, per loan $ 2,500 Interest Rate Lock Commitment 625 Historical Trend Closing Ratios 91.07 % Pricing Model Origination Costs, per loan $ 2,500 Total $ 17,767 Non-Recurring Fair Value Measurements The Company is required, on a non-recurring basis, to adjust the carrying value or provide valuation allowances for certain assets using fair value measurements in accordance with GAAP. The following is a summary of applicable non-recurring fair value measurements. There are no liabilities measured on a non-recurring basis.

(in thousands) December 31, 2014 Valuation Techniques Unobservable Inputs Range (Weighted Average) (a) Assets Impaired loans $ 5,820 Fair value of collateral Loss severity .31% to 38.7% (12.65%) Appraised value $5 to $1,600.0 ($912.7) Capitalized mortgage servicing rights 3,757 Discounted cash flow Constant prepayment rate (CPR) 7.83% to 19.00% (9.92%) Discount rate 10.00% to 13.00% (10.43%) Other real estate owned 2,049 Fair value of collateral Appraised value $57 to $700.0 ($462.6) Total Assets $ 11,626 (a) Where dollar amounts are disclosed, the amounts represent the lowest and highest fair value of the respective assets in the population except for adjustments for market/property conditions, which represents the range of adjustments to individuals properties. There were no Level 1 or Level 2 nonrecurring fair value measurements for year-end 2015 and 2014 . Impaired Loans. Loans are generally not recorded at fair value on a recurring basis. Periodically, the Company records non-recurring adjustments to the carrying value of loans based on fair value measurements for partial charge-offs of the uncollectible portions of those loans. Non-recurring adjustments can also include certain impairment amounts for collateral-dependent loans calculated when establishing the allowance for credit losses. Such amounts are generally based on the fair value of the underlying collateral supporting the loan and, as a result, the carrying value of the loan less the calculated valuation amount does not necessarily represent the fair value of the loan. Real estate collateral is typically valued using appraisals or other indications of value based on recent comparable sales of similar properties or assumptions generally observable in the marketplace. However, the choice of observable data is subject to significant judgment, and there are often adjustments based on judgment in order to make observable data comparable and to consider the impact of time, the condition of properties, interest rates, and other market factors on current values. Additionally, commercial real estate appraisals frequently involve discounting of projected cash flows, which relies inherently on unobservable data. Therefore, real estate collateral related nonrecurring fair value measurement adjustments have generally been classified as Level 3. Estimates of fair value for other collateral that supports commercial loans are generally based on assumptions not observable in the marketplace and therefore such valuations have been classified as Level 3. Capitalized mortgage loan servicing rights . A loan servicing right asset represents the amount by which the present value of the estimated future net cash flows to be received from servicing loans exceed adequate compensation for performing the servicing. The fair value of servicing rights is estimated using a present value cash flow model. The most important assumptions used in the valuation model are the anticipated rate of the loan prepayments and discount rates. Adjustments are only recorded when the discounted cash flows derived from the valuation model are less than the carrying value of the asset. Although some assumptions in determining fair value are based on standards used by market participants, some are based on unobservable inputs and therefore are classified in Level 3 of the valuation hierarchy. Other real estate owned (“OREO”). OREO results from the foreclosure process on residential or commercial loans issued by the Bank. Upon assuming the real estate, the Company records the property at the fair value of the asset less the estimated sales costs. Thereafter, OREO properties are recorded at the lower of cost or fair value less the estimated sales costs. OREO fair values are primarily determined based on Level 3 data including sales comparables and appraisals. Summary of Estimated Fair Values of Financial Instruments The estimated fair values, and related carrying amounts, of the Company’s financial instruments follow. Certain financial instruments and all non-financial instruments are excluded from disclosure requirements. Accordingly, the aggregate fair value amounts presented herein may not necessarily represent the underlying fair value of the Company.

Cash and cash equivalents. Carrying value is assumed to represent fair value for cash and cash equivalents that have original maturities of ninety days or less. Restricted equity securities. Carrying value approximates fair value based on the redemption provisions of the issuers. Cash surrender value of life insurance policies. Carrying value approximates fair value. Loans, net. The carrying value of the loans in the loan portfolio is based on their outstanding unpaid principal balances adjusted for charge-offs, the allowance for loan losses, the unamortized balance of any deferred fees or costs on originated loans and the unamortized balance of any premiums or discounts on loans purchased or acquired through mergers. The fair value of the loans is estimated by discounting future cash flows using the current interest rates at which similar loans with similar terms would be made to borrowers of similar credit quality. Accrued interest receivable. Carrying value approximates fair value. Deposits. The fair value of demand, non-interest bearing checking, savings and money market deposits is determined as the amount payable on demand at the reporting date. The fair value of time deposits is estimated by discounting the estimated future cash flows using market rates offered for deposits of similar remaining maturities. Borrowed funds.

SUMMARY OF SIGNIFICANT ACCOUN33

SUMMARY OF SIGNIFICANT ACCOUNTING POLICES (Policies)	12 Months Ended
	Dec. 31, 2015
Accounting Policies [Abstract]
Basis of Presentation and Consolidation	Basis of Presentation and Consolidation The consolidated financial statements (the “financial statements”) of Berkshire Hills Bancorp, Inc. and its subsidiaries (the “Company” or “Berkshire”) have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”). The Company is a Delaware corporation and the holding company for Berkshire Bank (the “Bank”), a Massachusetts-chartered savings bank headquartered in Pittsfield, Massachusetts, and Berkshire Insurance Group, Inc. (“Berkshire Insurance Group” or “BIG”). These financial statements include the accounts of the Company, its wholly-owned subsidiaries and the Bank’s consolidated subsidiaries. In consolidation, all significant intercompany accounts and transactions are eliminated. The results of operations of companies or assets acquired are included only from the dates of acquisition. All material wholly-owned and majority-owned subsidiaries are consolidated unless GAAP requires otherwise.
Reclassifications	Reclassifications Certain items in prior financial statements have been reclassified to conform to the current presentation. The Company has evaluated subsequent events for potential recognition and/or disclosure through the date these consolidated financial statements were issued.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent liabilities at the date of the financial statements. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses; the valuation of deferred tax assets; the estimates related to the initial measurement of goodwill and intangible assets and subsequent impairment analyses; the determination of other-than-temporary impairment of securities; and the determination of fair value of financial instruments and subsequent impairment analysis.
Business Combinations	Business Combinations Business combinations are accounted for using the acquisition method of accounting. Under this method, the accounts of an acquired entity are included with the acquirer’s accounts as of the date of acquisition with any excess of purchase price over the fair value of the net assets acquired (including identifiable intangibles) capitalized as goodwill. To consummate an acquisition, the Company will typically issue common stock and/or pay cash, depending on the terms of the acquisition agreement. The value of common shares issued is determined based upon the market price of the stock as of the closing of the acquisition.
Cash and Cash equivalents	Cash and Cash equivalents Cash and cash equivalents include cash, balances due from banks, and short-term investments, all of which mature within ninety days. Due to the nature of cash and cash equivalents and the near term maturity, the Company estimated that the carrying amount of such instruments approximated fair value. The nature of the Bank’s business requires that it maintain amounts due from banks which at times, may exceed federally insured limits. The Bank has not experienced any losses on such amounts and all amounts are maintained with well-capitalized institutions.
Trading Security	Trading Security The Company accounts for a tax advantaged economic development bond originated in 2008 at fair value, in accordance with Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification (“ASC”) 320. The bond has been designated as a trading account security and is recorded at fair value, with changes in unrealized gains and losses recorded through earnings each period as part of non-interest income.
Securities	Securities Debt securities that management has the intent and ability to hold to maturity are classified as held to maturity and carried at amortized cost. All other securities, including equity securities with readily determinable fair values, are classified as available for sale and carried at fair value, with unrealized gains and losses reported as a component of other net comprehensive income. Management determines the appropriate classification of securities at the time of purchase. Restricted equity securities, such as stock in the Federal Home Loan Bank of Boston (“FHLBB”) are carried at cost. There are no quoted market prices for the Company’s restricted equity securities. The Bank is a member of the FHLBB, which requires that members maintain an investment in FHLBB stock, which may be redeemed based on certain conditions. The Bank reviews for impairment based on the ultimate recoverability of the cost bases in the FHLBB stock. Purchase premiums and discounts are recognized in interest income using the interest method over the terms of the securities. Gains and losses on the sale of securities are recorded on the trade date and are determined using the specific identification method. The Company evaluates debt and equity securities within the Company’s available for sale and held to maturity portfolios for other-than-temporary impairment (“OTTI”), at least quarterly. If the fair value of a debt security is below the amortized cost basis of the security, OTTI is required to be recognized if any of the following are met: (1) the Company intends to sell the security; (2) it is “more likely than not” that the Company will be required to sell the security before recovery of its amortized cost basis; or (3) the present value of expected cash flows is not sufficient to recover the entire amortized cost basis. For all impaired debt securities that the Company intends to sell, or more likely than not will be required to sell, the full amount of the depreciation is recognized as OTTI through earnings. Credit-related OTTI for all other impaired debt securities is recognized through earnings. Non-credit related OTTI for such debt securities is recognized in other comprehensive income, net of applicable taxes. In evaluating its marketable equity securities portfolios for OTTI, the Company considers its intent and ability to hold an equity security to recovery of its cost basis in addition to various other factors, including the length of time and the extent to which the fair value has been less than cost and the financial condition and near term prospects of the issuer. Any OTTI on marketable equity securities is recognized immediately through earnings.
Loans Held for Sale	Loans Held for Sale Loans originated with the intent to be sold in the secondary market are accounted for under the fair value option. Non-refundable fees and direct loan origination costs related to residential mortgage loans held for sale are recognized in noninterest income or noninterest expense as earned or incurred. Fair value is primarily determined based on quoted prices for similar loans in active markets. Gains and losses on sales of residential mortgage loans (sales proceeds minus carrying value) are recorded in noninterest income. Loans that were previously held for investment that the Company has an active plan to sell are transferred to loans held for sale at the lower of cost or market (fair value). The market price is primarily determined based on quoted prices for similar loans in active markets or agreed upon sales prices. Gains are recorded in noninterest income at sale to the extent that the sale price of the loan exceeds carrying value. Any reduction in the loan’s value, prior to being transferred to loans held for sale, is reflected as a charge-off of the recorded investment in the loan resulting in a new cost basis, with a corresponding reduction in the allowance for loan losses. Further changes in the fair value of the loan are recognized in noninterest income or expense, accordingly.
Loans	Loans Loans are reported at their outstanding unpaid principal balances adjusted for charge-offs, the allowance for loan losses, the unamortized balance of any deferred fees or costs on originated loans and the unamortized balance of any premiums or discounts on loans purchased or acquired through mergers. Interest income is accrued on the unpaid principal balance. Interest income includes net accretion or amortization of deferred fees or costs and of premiums or discounts. Direct loan origination costs, net of any origination fees, in addition to premiums and discounts on loans, are deferred and recognized as an adjustment of the related loan yield using the interest method. Interest on loans, excluding automobile loans, is generally not accrued on loans which are ninety days or more past due unless the loan is well-secured and in the process of collection. Past due status is based on contractual terms of the loan. Automobile loans generally continue accruing until one hundred and twenty days delinquent, at which time they are charged off. All interest accrued but not collected for loans that are placed on non-accrual or charged-off is reversed against interest income, except for certain loans designated as well-secured. The interest on non-accrual loans is accounted for on the cash-basis or cost-recovery method, until qualifying for return to accrual. All payments received on non-accrual loans are applied against the principal balance of the loan. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured.
Acquired Loans	Acquired Loans Loans that the Company acquired in acquisitions are initially recorded at fair value with no carryover of the related allowance for credit losses. Determining the fair value of the loans involves estimating the amount and timing of principal and interest cash flows initially expected to be collected on the loans and discounting those cash flows at an appropriate market rate of interest. For loans that meet the criteria stipulated in ASC 310-30, “ Loans and Debt Securities Acquired with Deteriorated Credit Quality, ” the Company recognizes the accretable yield, which is defined as the excess of all cash flows expected at acquisition over the initial fair value of the loan, as interest income on a level-yield basis over the expected remaining life of the loan. The excess of the loan’s contractually required payments over the cash flows expected to be collected is the nonaccretable difference. The nonaccretable difference is not recognized as an adjustment of yield, a loss accrual, or a valuation allowance. Going forward, the Company continues to evaluate whether the timing and the amount of cash to be collected are reasonably expected. Subsequent significant increases in cash flows the Company expects to collect will first reduce any previously recognized valuation allowance and then be reflected prospectively as an increase to the level yield. Subsequent decreases in expected cash flows may result in the loan being considered impaired. Interest income is not recognized to the extent that the net investment in the loan would increase to an amount greater than the estimated payoff amount. For ASC 310-30 loans, the expected cash flows reflect anticipated prepayments, determined on a loan by loan basis according to the anticipated collection plan of these loans. The expected prepayments used to determine the accretable yield are consistent between the cash flows expected to be collected and projections of contractual cash flows so as to not affect the nonaccretable difference. For ASC 310-30 loans, prepayments result in the recognition of the nonaccretable balance as current period yield. Changes in prepayment assumptions may change the amount of interest income and principal expected to be collected. Interest income is also net of recoveries recorded on acquired impaired loans. For loans that do not meet the ASC 310-30 criteria, the Company accretes interest income based on the contractually required cash flows. The Company subjects loans that do not meet the ASC 310-30 criteria to ASC 450, “Contingencies” by collectively evaluating these loans for an allowance for loan loss. Acquired loans that met the criteria for nonaccrual of interest prior to the acquisition are considered performing upon acquisition, regardless of whether the customer is contractually delinquent, if the Company can reasonably estimate the timing and amount of the expected cash flows on such loans and if the Company expects to fully collect the new carrying value of the loans. As such, the Company may no longer consider the loan to be nonaccrual or nonperforming and may accrue interest on these loans, including the impact of any accretable yield. The Company has determined that the Company can reasonably estimate future cash flows on the Company’s current portfolio of acquired loans that are past due 90 days or more and on which the Company is accruing interest and the Company expects to fully collect the carrying value of the loans.
Allowance for Loan Losses	Allowance for Loan Losses The allowance for loan losses is established based upon the level of estimated probable losses in the current loan portfolio. Loan losses are charged against the allowance when management believes the collectability of a loan balance is doubtful. Subsequent recoveries, if any, are credited to the allowance. The allowance for loan losses includes allowance allocations calculated in accordance with ASC 310, “Receivables,” and allowance allocations calculated in accordance with ASC 450, “Contingencies.” The allowance for loan losses is allocated to loan types using both a formula-based approach applied to groups of loans and an analysis of certain individual loans for impairment. The formula-based approach emphasizes loss factors derived from actual historical and industry portfolio loss rates, which are combined with an assessment of certain qualitative factors to determine the allowance amounts allocated to the various loan categories. Allowance amounts are based on an estimate of historical average annual percentage rate of loan loss for each loan segment, a temporal estimate of the incurred loss emergence and confirmation period for each loan category, and certain qualitative risk factors considered in the computation of the allowance for loan losses. Qualitative risk factors impacting the inherent risk of loss within the portfolio include the following: • National and local economic conditions, regulatory/legislative changes, or other competitive factors affecting the collectability of the portfolio • Trends in underwriting characteristics, composition of the portfolio, and/or asset quality • Changes in underwriting standards and/or collection, charge off, recovery, and account management practice • The existence and effect of any concentrations of credit Risk characteristics relevant to each portfolio segment are as follows: Residential mortgage — The Company generally does not originate loans with a loan-to-value ratio greater than 80 percent and does not grant subprime loans. The Company requires private mortgage insurance (PMI) in cases when the loan-to-value ratio exceeds 80 percent . All loans in this segment are collateralized by residential real estate and repayment is dependent on the credit quality of the individual borrower. The overall health of the economy, including unemployment rates and housing prices, will have an effect on the credit quality in this segment. Commercial real estate — Loans in this segment are primarily owner-occupied or income-producing properties throughout New England and Northeastern New York. The underlying cash flows generated by the properties are adversely impacted by a downturn in the economy, which in turn, will have an effect on the credit quality in this segment. Management monitors the cash flows of these loans. In addition, construction loans in this segment primarily include real estate development loans for which payment is derived from sale of the property or long term financing at completion. Credit risk is affected by cost overruns, time to sell at an adequate price, and market conditions. Commercial and industrial loans — Loans in this segment are made to businesses and are generally secured by assets of the business. Repayment is expected from the cash flows of the business. Loans in this segment include asset based loans which generally have no scheduled repayment and which are closely monitored against formula based collateral advance ratios. A weakened economy, and resultant decreased consumer spending, will have an effect on the credit quality in this segment. Consumer loans — Loans in this segment are primarily home equity lines of credit and second mortgages, together with automobile loans and other consumer loans. The overall health of the economy, including unemployment rates and housing prices, will have an effect on the credit quality in this segment. The Company utilizes a blend of historical and industry portfolio loss rates for commercial mortgage and commercial business loans that are assessed by internal risk rating. Historical loss rates for residential mortgages, home equity and other consumer loans are not risk graded but are assessed based on the total of each loan segment. This approach incorporates qualitative adjustments based upon management’s assessment of various market and portfolio specific risk factors into its formula-based estimate. Due to the imprecise nature of the loan loss estimation process and ever changing conditions, the qualitative risk attributes may not adequately capture amounts of incurred loss in the formula-based loan loss components used to determine allocations in the Company’s analysis of the adequacy of the allowance for loan losses. The Company evaluates certain loans individually for specific impairment. Large groups of small balance homogeneous loans such as the residential mortgage, home equity, and other consumer portfolios are collectively evaluated for impairment. A loan is considered impaired when, based on current information and events, it is probable that the Company will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement. Factors considered by management in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Loans are selected for evaluation based upon a change in internal risk rating, occurrence of delinquency, loan classification, or non-accrual status. The evaluation of certain loans individually for specific impairment includes loans that were previously classified as Troubled Debt Restructurings (“TDRs”) or continue to be classified as TDRs. A specific allowance amount is allocated to an individual loan when such loan has been deemed impaired and when the amount of the probable loss is able to be estimated. Estimates of loss may be determined by the present value of anticipated future cash flows or the loan’s observable fair market value, or the fair value of the collateral, if the loan is collateral dependent. However, for collateral dependent loans, the amount of the recorded investment in a loan that exceeds the fair value of the collateral is charged-off against the allowance for loan losses in lieu of an allocation of a specific allowance amount when such an amount has been identified definitively as uncollectible.
Bank-Owned Life Insurance	Bank-Owned Life Insurance Bank-owned life insurance policies are reflected on the consolidated balance sheets at cash surrender value. Changes in the net cash surrender value of the policies, as well as insurance proceeds received, are reflected in non-interest income on the consolidated statements of operations and are not subject to income taxes.
Foreclosed and Repossessed Assets	Foreclosed and Repossessed Assets Assets acquired through, or in lieu of, loan foreclosure or repossession are held for sale and are initially recorded at the lower of the investment in the loan or fair value less estimated costs to sell at the date of foreclosure or repossession, establishing a new cost basis. Subsequently, valuations are periodically performed by management and the assets are carried at the lower of carrying amount or fair value less estimated costs to sell. Revenue and expenses from operations, changes in the valuation allowance, any direct write-downs and gains or losses on sales are included in other real estate owned expense.
Capitalized Mortgage Servicing Rights	Capitalized Mortgage Servicing Rights Capitalized mortgage servicing rights are included in “other assets” in the consolidated balance sheet. Servicing assets are initially recognized as separate assets at fair value when rights are acquired through purchase or through sale of financial assets with servicing retained. The Company uses the amortization method to subsequently measure servicing assets. Under that method, capitalized mortgage servicing rights are charged to expense in proportion to and over the period of estimated net servicing income. Fair value of the mortgage servicing rights is based on a valuation model that calculates the present value of estimated future net servicing income. The valuation model incorporates assumptions that market participants would use in estimating future net servicing income, such as the cost to service, the discount rate, prepayment speeds and default rates and losses. Impairment is recognized through a valuation allowance for an individual tranche, to the extent that fair value is less than the capitalized amount for the tranches. If the Company later determines that all or a portion of the impairment no longer exists for a particular tranche, a reduction of the allowance may be recorded as an increase to income.
Premises and Equipment	Premises and Equipment Land is carried at cost. Buildings, improvements, and equipment are carried at cost, less accumulated depreciation and amortization computed on the straight-line method over the estimated useful lives of the assets. Leasehold improvements are amortized over the initial term of the lease, plus optional terms if certain conditions are met.
Goodwill	Goodwill Goodwill represents the excess of the purchase price over the fair value of the net assets acquired in a business combination. Goodwill is assigned to reporting units, which are operating segments or one level below an operating segment. Goodwill is assigned to the Company’s reporting units that are expected to benefit from the business combination. Goodwill is assessed annually for impairment, and more frequently if events or changes in circumstances indicate that there may be an impairment. Adverse changes in the economic environment, declining operations, unanticipated competition, loss of key personnel, or other factors could result in a decline in the implied fair value of goodwill. If the implied fair value of goodwill is less than the carrying amount, a loss would be recognized in other noninterest expense to reduce the carrying amount to the implied fair value of goodwill. A goodwill impairment analysis is comprised of two steps. Step 1, used to identify instances of potential impairment, compares the fair value of a reporting unit with its carrying amount, including goodwill. If the fair value of a reporting unit exceeds its carrying amount, including goodwill, the reporting unit’s goodwill is not considered impaired. If the carrying amount of a reporting unit, including goodwill, exceeds its fair value, the second step of the goodwill impairment analysis is performed to measure the amount of impairment loss, if any. Step 2 of the goodwill impairment analysis compares the implied fair value of reporting unit goodwill with the carrying amount of that goodwill. If the carrying amount of goodwill for that reporting unit exceeds the implied fair value of that reporting unit’s goodwill, an impairment loss is recognized in an amount equal to that excess. Subsequent reversals of goodwill impairment are prohibited.
Other Intangibles	Other Intangibles Intangible assets are acquired assets that lack physical substance but can be distinguished from goodwill because of contractual or other legal rights or the asset is capable of being sold or exchanged either on its own or in combination with a related contract, asset or liability. The fair values of these assets are generally determined based on appraisals and are subsequently amortized on a straight-line basis or an accelerated basis over their estimated lives. Management assesses the recoverability of these intangible assets whenever events or changes in circumstances indicate that their carrying value may not be recoverable. If the carrying amount exceeds fair value, an impairment charge is recorded to income.
Transfers of Financial Assets	Transfers of Financial Assets Transfers of an entire financial asset, group of entire financial assets, or a participating interest in an entire financial asset are accounted for as sales when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when (1) the assets have been isolated from the Company, (2) the transferee obtains the right to pledge or exchange the transferred assets, and (3) the Company does not maintain effective control over the transferred assets.
Income Taxes	Income Taxes Deferred income taxes are recognized for the tax consequences of temporary differences by applying enacted statutory tax rates applicable for future years to differences between financial statement and tax bases of existing assets and liabilities. The effect of tax rate changes on deferred taxes is recognized in the income tax provision in the period that includes the enactment date. A tax valuation allowance is established, as needed, to reduce net deferred tax assets to the amount expected to be realized. In the event it becomes more likely than not that some or all of the deferred tax asset allowances will not be needed, the valuation allowance will be adjusted. In the ordinary course of business there is inherent uncertainty in quantifying the Company’s income tax positions. Income tax positions and recorded tax benefits are based upon management’s evaluation of the facts, circumstances, and information available at the reporting date. For those tax positions where it is more likely than not that a tax benefit will be sustained, we have determined the amount of the tax benefit to be recognized by estimating the largest amount of tax benefit that has a greater than 50% likelihood of being realized upon ultimate settlement with a taxing authority that has full knowledge of all relevant information. For those income tax positions where it is not more-likely-than-not that a tax benefit will be sustained, no tax benefit has been recognized in the financial statements. Where applicable, associated interest and penalties has also been recognized. We recognize accrued interest and penalties related to unrecognized tax benefits as a component of income tax expense.
Insurance Commissions	Insurance Commissions Commission revenue is recognized as of the effective date of the insurance policy or the date the customer is billed, whichever is later, net of return commissions related to policy cancellations. In addition, the Company may receive additional performance commissions based on achieving certain sales and loss experience measures. Such commissions are recognized when determinable, which is generally when such commissions are received or when the Company receives data from the insurance companies that allows the reasonable estimation of these amounts.
Advertising Costs	Advertising Costs Advertising costs are expensed as incurred.
Stock-Based Compensation	Stock-Based Compensation The Company measures and recognizes compensation cost relating to share-based payment transactions based on the grant-date fair value of the equity instruments issued. The fair value of restricted stock is recorded as unearned compensation. The deferred expense is amortized to compensation expense based on one of several permitted attribution methods over the longer of the required service period or performance period. For performance-based restricted stock awards, the Company estimates the degree to which performance conditions will be met to determine the number of shares that will vest and the related compensation expense. Compensation expense is adjusted in the period such estimates change. Income tax benefits related to stock compensation in excess of grant date fair value, less any proceeds on exercise, are recognized as an increase to additional paid-in capital upon vesting or exercising and delivery of the stock. Any income tax benefits that are less than grant date fair value less any proceeds on exercise would be recognized as a reduction of additional paid-in capital to the extent of previously recognized income tax benefits and then as compensation expense for the remaining amount.
Earnings per Common Share	Earnings per Common Share Basic earnings per share represents income available to common stockholders divided by the weighted-average number of common shares outstanding during the period. If rights to dividends on unvested options/awards are non-forfeitable, these unvested awards/options are considered outstanding in the computation of basic earnings per share. Diluted earnings per share reflects additional common shares that would have been outstanding if dilutive potential common shares had been issued, as well as any adjustments to income that would result from the assumed issuance. Potential common shares that may be issued by the Company relate to outstanding stock options and restricted stock awards and are determined using the treasury stock method. Treasury shares are not deemed outstanding for earnings per share calculations.
Wealth Management	Wealth Management Wealth management assets held in a fiduciary or agent capacity are not included in the accompanying consolidated balance sheets because they are not assets of the Company. Fees earned from wealth management activities are amortized over the period of the service performed.
Derivative Instruments and Hedging Activities	Derivative Instruments and Hedging Activities The Company enters into interest rate swap agreements as part of the Company’s interest rate risk management strategy for certain assets and liabilities and not for speculative purposes. Based on the Company’s intended use for the interest rate swap at inception, the Company designates the derivative as either an economic hedge of an asset or liability or a hedging instrument subject to the hedge accounting provisions of ASC 815, “Derivatives and Hedging.” Interest rate swaps designated as economic hedges are recorded at fair value within other assets or liabilities. Changes in the fair value of these derivatives are recorded directly through earnings. For interest rate swaps that management intends to apply the hedge accounting provisions of ASC 815, the Company formally documents at inception all relationships between hedging instruments and hedged items, as well as its risk management objectives and strategies for undertaking the various hedges. Additionally, the Company uses dollar offset or regression analysis at the hedge’s inception and for each reporting period thereafter, to assess whether the derivative used in its hedging transaction is expected to be and has been highly effective in offsetting changes in the fair value or cash flows of the hedged item. The Company discontinues hedge accounting when it is determined that a derivative is not expected to be or has ceased to be highly effective as a hedge, and then reflects changes in fair value of the derivative in earnings after termination of the hedge relationship. The Company has characterized its interest rate swaps that qualify under ASC 815 hedge accounting as cash flow hedges. Cash flow hedges are used to minimize the variability in cash flows of assets or liabilities, or forecasted transactions caused by interest rate fluctuations, and are recorded at fair value in other assets or liabilities within the Company’s balance sheets. Changes in the fair value of these cash flow hedges are initially recorded in accumulated other comprehensive loss and subsequently reclassified into earnings when the forecasted transaction affects earnings. Any hedge ineffectiveness assessed as part of the Company’s quarterly analysis is recorded directly to earnings. The Company enters into interest rate lock commitments with borrowers, and forward commitments to sell loans or to-be-announced mortgage-backed bonds to investors to hedge against the inherent interest rate and pricing risk associated with selling loans. The interest rate lock commitments generally terminate once the loan is funded, the lock period expires or the borrower decides not to contract for the loan. The forward commitments generally terminate once the loan is sold, the commitment period expires or the borrower decides not to contract for the loan. These commitments are considered derivatives which are accounted for by recognizing their estimated fair value on the Consolidated Balance Sheets as either a freestanding asset or liability. See Note 16 to the Consolidated Financial Statements for more information on interest rate lock commitments and forward commitments.
Off-Balance Sheet Financial Instruments	Off-Balance Sheet Financial Instruments In the ordinary course of business, the Company enters into off-balance sheet financial instruments, consisting primarily of credit related financial instruments. These financial instruments are recorded in the financial statements when they are funded or related fees are incurred or received.
Fair Value Hierarchy	Fair Value Hierarchy The Company groups assets and liabilities that are measured at fair value in three levels, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value. Level 1 — Valuation is based on quoted prices in active markets for identical assets or liabilities. Valuations are obtained from readily available pricing sources for market transactions involving identical assets or liabilities. Level 2 — Valuation is based on observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 3 — Valuation is based on unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Level 3 assets and liabilities include financial instruments whose value is determined using unobservable techniques, as well as instruments for which the determination of fair value requires significant management judgment or estimation.
Employee Benefits	Employee Benefits The Company maintains an employer sponsored 401(k) plan to which participants may make contributions in the form of salary deferrals and the Company provides matching contributions in accordance with the terms of the plan. Contributions due under the terms of the defined contribution plans are accrued as earned by employees. Due to the Rome Bancorp acquisition in 2011, the Company inherited a noncontributory, qualified, defined benefit pension plan for certain employees who met age and service requirements; as well as other post-retirement benefits, principally health care and group life insurance. The Rome pension plan and postretirement benefits that were acquired in connection with the whole-bank acquisition in the second quarter of 2011 were frozen prior to the close of the transaction. The pension benefit in the form of a life annuity is based on the employee’s combined years of service, age, and compensation. The Company also has a long-term care post-retirement benefit plan for certain executives where upon disability, associated benefits are funded by insurance policies or paid directly by the Company. In order to measure the expense associated with the Plans, various assumptions are made including the discount rate, expected return on plan assets, anticipated mortality rates, and expected future healthcare costs. The assumptions are based on historical experience as well as current facts and circumstances. The Company uses a December 31 measurement date for its Plans. As of the measurement date, plan assets are determined based on fair value, generally representing observable market prices. The projected benefit obligation is primarily determined based on the present value of projected benefit distributions at an assumed discount rate. Net periodic pension benefit costs include interest costs based on an assumed discount rate, the expected return on plan assets based on actuarially derived market-related values, and the amortization of net actuarial losses. Net periodic postretirement benefit costs include service costs, interest costs based on an assumed discount rate, and the amortization of prior service credits and net actuarial gains. Differences between expected and actual results in each year are included in the net actuarial gain or loss amount, which is recognized in other comprehensive income. The net actuarial gain or loss in excess of a 10% corridor is amortized in net periodic benefit cost over the average remaining service period of active participants in the Plans. The prior service credit is amortized over the average remaining service period to full eligibility for participating employees expected to receive benefits. The Company recognizes in its statement of condition an asset for a plan’s overfunded status or a liability for a plan’s underfunded status. The Company also measures the Plans’ assets and obligations that determine its funded status as of the end of the fiscal year and recognizes those changes in other comprehensive income, net of tax.
Operating Segments	Operating Segments In prior periods, the Company reported two subsidiary operating segments -- banking and insurance. Due to continued growth solely in the banking segment, including two acquisitions in the current year, management determined as of the fiscal year-end 2015 the Company operates as one consolidated reportable segment. The chief operating decision-maker evaluates consolidated results and makes decisions for resource allocation on this same data. Management periodically reviews and redefines its segment reporting as internal reporting practices evolve and components of the business change. The consolidated financial statements reflect the financial results of the Company's one reportable operating segment.
Recent Accounting Pronouncements and Future Application of Accounting Pronouncements	Recently Adopted Accounting Principles In January 2014, the Financial Accounting Standard Board “FASB” issued Accounting Standard Updated “ASU” ASU No. 2014-01, “Accounting for Investments in Qualified Affordable Housing Projects.” ASU No. 2014-01 permits reporting entities to make an accounting policy election to account for investments in qualified affordable housing projects using the proportional amortization method if certain conditions are met. Under the proportional amortization method, an entity amortizes the initial cost of the investment in proportion to the tax credits and other tax benefits received and recognizes the net investment performance in the income statement as a component of income tax expense. This new guidance also requires new disclosures for all investors in these projects. ASU No. 2014-01 is effective for interim and annual reporting periods beginning after December 15, 2014. Upon adoption, the guidance must be applied retrospectively to all periods presented. However, entities that use the effective yield method to account for investments in these projects before adoption may continue to do so for these pre-existing investments. The Company has elected not to adopt the proportional amortization method, which had no impact on our consolidated financial statements. Also in January 2014, the FASB issued ASU No. 2014-04, “Reclassification of Residential Real Estate Collateralized Consumer Mortgage Loans upon Foreclosure.” The objective of this guidance is to clarify when an in substance repossession or foreclosure occurs, that is, when a creditor should be considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan such that the loan receivable should be derecognized and the real estate property recognized. ASU No. 2014-04 states that an in substance repossession or foreclosure occurs, and a creditor is considered to have received physical possession of residential real estate property collateralizing a consumer mortgage loan, upon either (1) the creditor obtaining legal title to the residential real estate property upon completion of a foreclosure or (2) the borrower conveying all interest in the residential real estate property to the creditor to satisfy that loan through completion of a deed in lieu of foreclosure or through a similar legal agreement. Additionally, ASU No. 2014-04 requires interim and annual disclosure of both (1) the amount of foreclosed residential real estate property held by the creditor and (2) the recorded investment in consumer mortgage loans collateralized by residential real estate property that are in the process of foreclosure according to local requirements of the applicable jurisdiction. ASU No. 2014-04 is effective for interim and annual reporting periods beginning after December 15, 2014. The Company adopted the provisions of ASU No. 2014-04 effective January 1, 2015, which did not have a material effect on our consolidated financial statements. See Note 6. Loan Loss Allowance to the Consolidated Financial Statements for the disclosures required by ASU No. 2014-04. In June 2014, the FASB issued ASU No. 2014-11 related to repurchase-to-maturity transactions, repurchase financing and disclosures. The pronouncement changes the accounting for repurchase-to-maturity transactions and linked repurchase financings to secured borrowing accounting, which is consistent with the accounting for other repurchase agreements. The pronouncement also requires two new disclosures. The first disclosure requires an entity to disclose information on transfers accounted for as sales in transactions that are economically similar to repurchase agreements. The second disclosure provides increased transparency about the types of collateral pledged in repurchase agreements and similar transactions accounted for as secured borrowings. The pronouncement is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2014. Early adoption is not permitted. As of December 31, 2015, the Company did not have any repurchase transactions, and therefore the adoption of this pronouncement did not have an impact on our consolidated financial statements. In August 2014, the FASB issued ASU No. 2014-14 related to classification of certain government-guaranteed mortgage loans upon foreclosure. The objective of this guidance is to reduce diversity in practice related to how creditors classify government- guaranteed mortgage loans, including FHA or VA guaranteed loans, upon foreclosure. Some creditors reclassify those loans to real estate consistent with other foreclosed loans that do not have guarantees; others reclassify the loans to other receivables. The amendments in this guidance require that a mortgage loan be derecognized and that a separate other receivable be recognized upon foreclosure if the following conditions are met: (1) The loan has a government guarantee that is not separable from the loan before foreclosure; (2) At the time of foreclosure, the creditor has the intent to convey the real estate property to the guarantor and make a claim on the guarantee, and the creditor has the ability to recover under that claim; and (3) At the time of foreclosure, any amount of the claim that is determined on the basis of the fair value of the real estate is fixed. Upon foreclosure, the separate other receivable should be measured based on the amount of the loan balance (principal and interest) expected to be recovered from the guarantor. The pronouncement is effective for interim and annual reporting periods beginning after December 15, 2014. The Company adopted the provisions of ASU No. 2014-14 effective January 1, 2015, which did not have a material effect on our consolidated financial statements Future Application of Accounting Pronouncements In May 2014, the FASB issued ASU No. 2014-09 related to the recognition of revenue from contracts with customers. The new revenue pronouncement creates a single source of revenue guidance for all companies in all industries and is more principles-based than current revenue guidance. The pronouncement provides a five-step model for a company to recognize revenue when it transfers control of goods or services to customers at an amount that reflects the consideration to which it expects to be entitled in exchange for those goods or services. The five steps are (1) identify the contract with the customer, (2) identify the separate performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price to the separate performance obligations and (5) recognize revenue when each performance obligation is satisfied. The standard is effective for public entities for interim and annual reporting periods beginning after December 15, 2016; early adoption is not permitted. However, in July 2015, the FASB voted to approve deferring the effective date by one year (i.e., interim and annual reporting periods beginning after December 15, 2017). Early adoption is permitted, but not before the original effective date (i.e., interim and annual reporting periods beginning after December 15, 2016). For financial reporting purposes, the standard allows for either full retrospective adoption, meaning the standard is applied to all of the periods presented, or modified retrospective adoption, meaning the standard is applied only to the most current period presented in the financial statements with the cumulative effect of initially applying the standard recognized at the date of initial application. The Company is currently evaluating the provisions of ASU No. 2014-09, and will be closely monitoring developments and additional guidance to determine the potential impact the new standard will have on our consolidated financial statements. In February 2015, the FASB issued ASU No. 2015-02, “Amendments to the Consolidation Analysis.” This ASU affects reporting entities that are required to evaluate whether they should consolidate certain legal entities. Specifically, the amendments: (1) Modify the evaluation of whether limited partnerships and similar legal entities are variable interest entities (“VIEs”) or voting interest entities; (2) Eliminate the presumption that a general partner should consolidate a limited partnership; (3) Affect the consolidation analysis of reporting entities that are involved with VIEs, particularly those that have fee arrangements and related party relationships; and (4) Provide a scope exception from consolidation guidance for reporting entities with interests in legal entities that are required to comply with or operate in accordance with requirements that are similar to those in Rule 2a-7 of the Investment Company Act of 1940 for registered money market funds. ASU No. 2015-02 is effective for reporting periods beginning after December 15, 2015. The adoption of this pronouncement is not expected to have a material impact on our consolidated financial statements. In April 2015, the FASB issued ASU No. 2015-03, “Simplifying the Presentation of Debt Issuance Costs.” This ASU requires that debt issuance costs be reported in the balance sheet as a direct deduction from the face amount of the related liability, consistent with the presentation of debt discounts. Further, the update requires the amortization of debt issuance costs to be reported as interest expense. Similarly, debt issuance costs and any discount or premium are considered in the aggregate when determining the effective interest rate on the debt. The new guidance is effective for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. The new guidance must be applied retrospectively. The adoption of this pronouncement is not expected to have a material impact on our consolidated financial statements. In April 2015, the FASB issued ASU No. 2015-05, “Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement.” This ASU provides guidance to customers about whether a cloud computing arrangement includes a software license. If a cloud computing arrangement includes a software license, the customer should account for the license element of the arrangement consistent with the acquisition of other software licenses. If a cloud computing arrangement does not include a software license, the customer should account for the arrangement as a service contract. The new guidance does not change the accounting for a customer’s accounting for service contracts. ASU No. 2015-05 is effective for fiscal years beginning after December 15, 2015. The adoption of this pronouncement is not expected to have a material impact on our consolidated financial statements. In September 2015, the FASB issued ASU No. 2015-16, “Business Combinations: Simplifying the Accounting for Measurement-Period Adjustments.” This ASU eliminates the requirement to retrospectively adjust the financial statements for measurement-period adjustments that occur in periods after a business combination is consummated. Measurement period adjustments are calculated as if they were known at the acquisition date, but are recognized in the reporting period in which they are determined. Additional disclosures are required about the impact on current-period income statement line items of adjustments that would have been recognized in prior periods if prior-period information had been revised. The guidance is effective for annual periods beginning after December 15, 2015 and is to be applied prospectively to adjustments of provisional amounts that occur after the effective date. Early application is permitted. The adoption of this pronouncement is not expected to have a material impact on our consolidated financial statements. In November 2015, the FASB issued ASU No. 2015-17, “Balance Sheet Classification of Deferred Taxes.” This ASU requires that deferred tax liabilities and assets be classified as noncurrent in a classified statement of financial position. The new guidance is effective for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years. The new guidance may be applied either prospectively to all deferred tax liabilities and assets or retrospectively to all periods presented. The adoption of this pronouncement is not expected to have a material impact on our consolidated financial statements. In January 2016, the FASB issued ASU No. 2016-01, “Recognition and Measurement of Financial Assets and Financial Liabilities.” This ASU requires an entity to: i) measure equity investments at fair value through net income, with certain exceptions; (ii) present in other comprehensive income the changes in instrument-specific credit risk for financial liabilities measured using the fair value option; (iii) present financial assets and financial liabilities by measurement category and form of financial asset; (iv) calculate the fair value of financial instruments for disclosure purposes based on an exit price and; (v) assess a valuation allowance on deferred tax assets related to unrealized losses of AFS debt securities in combination with other deferred tax assets. The guidance provides an election to subsequently measure certain nonmarketable equity investments at cost less any impairment and adjusted for certain observable price changes. The guidance also requires a qualitative impairment assessment of such equity investments and amends certain fair value disclosure requirements. The guidance is effective for annual periods beginning after December 15, 2017. Early adoption is only permitted for the provision related to instrument-specific credit risk, The Company is currently evaluating the impact of the new standard on the consolidated financial statements.

Summary of Consideration Paid, and Fair Values of the Assets Acquired and Liabilities Assumed	The following table provides a summary of the assets acquired and liabilities assumed as recorded by Firestone and the associated provisional fair value adjustments. As provided for under GAAP, management has a measurement period of up to 12 months following the date of acquisition to finalize the fair values of the acquired assets and assumed liabilities to reflect new information obtained about facts and circumstances that existed as of the acquisition date. The table summarizes the estimates of the resultant fair values of those assets and liabilities as recorded by the Company; no material adjustments were made since the provisional estimates were recorded at September 30, 2015. Consideration paid, and fair values of Firestone’s assets acquired and liabilities assumed, along with the resulting goodwill, are summarized in the following table: Fair Value As Recorded by (in thousands) As Acquired Adjustments the Company Consideration Paid: Berkshire Hills Bancorp common stock issued to Firestone common stockholders $ 42,107 Cash paid to Firestone common stockholders 13,887 Total merger consideration (1) $ 55,994 Recognized amounts of identifiable assets acquired and (liabilities) assumed, at fair value: Cash $ 4,577 $ — $ 4,577 Loans 194,622 (2,668 ) (a) 191,954 Premises and equipment 1,356 (835 ) (b) 521 Deferred tax assets, net 162 2,850 (c) 3,012 Other assets 1,863 (1,002 ) (d) 861 Borrowings (1) (159,312 ) — (159,312 ) Other liabilities (3,198 ) 76 (e) (3,122 ) Total identifiable net assets $ 40,070 $ (1,579 ) $ 38,491 Goodwill $ 17,503 (1) Amounts exclude $11.8 million of Firestone's commercial loan with the Company, which was effectively settled upon acquisition. Amounts also include a $0.5 million in-transit cash payment to Firestone common stockholders. ________________________________ Explanation of Certain Fair Value Adjustments (a) The adjustment represents a write-down of the book value of loans to their estimated fair value based on current interest rates and expected cash flows, which includes an estimate of expected loan loss inherent in the portfolio. Loans that met the criteria and are being accounted for in accordance with ASC 310-30 had a book value of $5.4 million and had a fair value $1.5 million . Non-impaired loans accounted for under ASC 310-20 had a book value of $192.7 million and had a fair value of $190.4 million . ASC 310-30 loans included a $0.8 million fair value adjustment that is accretable in earnings over an estimated three year life using the effective yield as determined on the date of acquisition. The effective yield is periodically adjusted for changes in expected flows. ASC 310-20 loans have a $2.3 million fair value adjustment discount that is amortized into earnings over the remaining term of the loans using the effective interest method. (b) The adjustment is a write-off of capitalized costs associated with Firestone’s internally developed accounting software, the development of which has been ceased due to pending conversion of Firestone’s accounting system to the Company’s existing system. (c) Represents net deferred tax assets resulting from the fair value adjustments related to the acquired assets and liabilities, identifiable intangibles, and other purchase accounting adjustments. (d) The adjustment consists of a $0.8 million write-off of capitalized loan costs due to no future economic benefits, a $117 thousand write-off of equipment held for sale due to an estimated zero resale value, and a $75 thousand swap termination fee for prepayment of Firestone’s borrowings. (e) The adjustment is a write-off of a deferred rent accrual. The following table provides a summary of the assets acquired and liabilities assumed as recorded by Hampden and the associated provisional fair value adjustments. As provided for under GAAP, management has a measurement period of up to 12 months following the date of acquisition to finalize the fair values of the acquired assets and assumed liabilities to reflect new information obtained about facts and circumstances that existed as of the acquisition date. Once management has finalized the fair values within the measurement period, management considers such values to be the day one fair values. The table summarizes the estimates of the resultant fair values of those assets and liabilities as recorded by the Company; no material adjustments were made since the provisional estimates were recorded at June 30, 2015. Fair Value As Recorded by (in thousands) As Acquired Adjustments the Company Consideration paid: Berkshire Hills Bancorp common stock issued to Hampden common stockholders $ 114,470 Fair value of Hampden shares previously owned by the Company prior to acquisition 4,632 Total consideration paid 119,102 Recognized amounts of identifiable assets acquired and (liabilities) assumed, at fair value: Cash and short-term investments $ 83,134 $ — $ 83,134 Investment securities 72,439 (224 ) (a) 72,215 Loans 501,870 (8,405 ) (b) 493,465 Premises and equipment 4,449 775 (c) 5,224 Core deposit intangibles — 2,780 (d) 2,780 Deferred tax assets, net 3,875 2,723 (e) 6,598 Other assets 22,919 856 (f) 23,775 Deposits (482,130 ) (1,439 ) (g) (483,569 ) Borrowings (117,135 ) (1,396 ) (h) (118,531 ) Other liabilities (8,395 ) (107 ) (i) (8,502 ) Total identifiable net assets $ 81,026 $ (4,437 ) $ 76,589 Goodwill $ 42,513 ________________________________ Explanation of Certain Fair Value Adjustments (a) The adjustment represents the write down of the book value of securities to their estimated fair value based on estimates at the date of acquisition. (b) The adjustment represents the write down of the book value of loans to their estimated fair value based on interest rates and expected cash flows as of the acquisition date, which includes an estimate of expected loan loss inherent in the portfolio. Loans that met the criteria and are being accounted for in accordance with ASC 310-30 had a carrying amount of $28.5 million and had a fair value of $16.7 million . Non-impaired loans not accounted for under ASC 310-20 had a book value of $473.4 million and have a fair value of $477.1 million . ASC 310-30 loans have a $4.0 million fair value adjustment that is accretable in earnings over an estimated five -year life using the effective yield as determined on the date of acquisition. The effective yield is periodically adjusted for changes in expected flows. ASC 310-20 loans have a $0.4 million fair value adjustment premium that is amortized into expense over the remaining term of the loans using the effective interest method, or a straight-line method if the loan is a revolving credit facility. (c) The amount represents the adjustment of the book value of buildings, and furniture and equipment, to their estimated fair value based on appraisals and other methods. The adjustments will be depreciated over the estimated economic lives of the assets. (d) The adjustment represents the value of the core deposit base assumed in the acquisition. The core deposit asset was recorded as an identifiable intangible asset and will be amortized over the estimated useful life of the deposit base. (e) Represents net deferred tax assets resulting from the fair value adjustments related to the acquired assets and liabilities, identifiable intangibles, and other purchase accounting adjustments. (f) The amount consists of a $0.2 million fair value adjustment to write-down other real estate owned based on market report data, a $0.3 million write-down of mortgage servicing assets acquired based on valuation reports, a $0.5 million write-off of prepaid assets due to obsolescence, and a $1.6 million measurement period adjustment increase to current taxes receivable. These adjustments are not accretable into earnings in the statement of income. (g) The adjustment is necessary because the weighted average interest rate of time deposits exceeded the cost of similar funding at the time of acquisition. The amount will be amortized using an accelerated method over the estimated useful life of two years. (h) Adjusts borrowings to their estimated fair value, which is calculated based on the expected future cash flow of the borrowings. (i) Adjusts the book value of other liabilities to their estimated fair value at the acquisition date. The adjustment consists of a $0.4 million write-off of deferred revenue, a $0.3 million increase to post-retirement liabilities due to change-in-control provisions, and a $0.2 million increase related to non-level leases.
