BASIS OF PRESENTATION

BASIS OF PRESENTATION	3 Months Ended

Organization, Consolidation and Presentation of Financial Statements [Abstract]
BASIS OF PRESENTATION	BASIS OF PRESENTATION The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and contain all adjustments, consisting solely of normal, recurring adjustments, necessary for a fair presentation of results for such periods. In addition, these interim financial statements have been prepared in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X, and accordingly, certain information and footnote disclosures normally included in financial statements prepared according to U.S. GAAP have been omitted. The results for any interim period are not necessarily indicative of results for the full year. These consolidated financial statements should be read in conjunction with the audited financial statements and note disclosures for Berkshire Hills Bancorp, Inc. (the “Company”) previously filed with the Securities and Exchange Commission in the Company’s Annual Report on Form 10-K for the year ended December 31, 2015. Reclassifications Certain items in prior financial statements have been reclassified to conform to the current presentation. Recently Adopted Accounting Principles 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 Company adopted the provisions of ASU No. 2015-02 effective January 1, 2016, which did not have a material effect on the Company's consolidated financial statements. See Note 7. Borrowed Funds to the Consolidated Financial statements for more information. In April 2015, the FASB issued ASU No. 2015-03, “Simplifying the Presentation of Debt Issuance Costs.” This ASU requires that debt issuance costs, not including those related to line of credit arrangements, 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 Company adopted the provisions of ASU No. 2015-03 effective January 1, 2016, which did not have a material effect on the Company's 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 Company adopted the provisions of ASU No. 2015-05 effective January 1, 2016, which did not have a material effect on the Company's 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 Company adopted the provisions of ASU No. 2015-16 effective January 1, 2016, which did not have a material effect on the Company's 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), issuing ASU 2015-14 “Revenue from Contracts with Customers -Deferral of the Effective Date.” 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 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. In February 2016, the FASB issued ASU No. 2016-02, “Leases”. The new pronouncement improves the transparency and comparability of financial reporting around leasing transactions and more closely aligns accounting for leases with the recently issued International Financial Reporting Standard. The pronouncement affects all entities that are participants to leasing agreements. From a lessee accounting perspective, the ASU requires a lessee to recognize assets and liabilities on the balance sheet for operating leases and changes many key definitions, including the definition of a lease. The ASU includes a short-term lease exception for leases with a term of twelve months or less, in which a lessee can make an accounting policy election not to recognize lease assets and lease liabilities. Lessees will continue to differentiate between finance leases (previously referred to as capital leases) and operating leases, using classification criteria that are substantially similar to the previous guidance. For lessees, the recognition, measurement, and presentation of expenses and cash flows arising from a lease have not significantly changed from previous GAAP. From a lessor accounting perspective, the guidance is largely unchanged, except for targeted improvements to align with new terminology under lessee accounting and with the updated revenue recognition guidance in Topic 606. For sale-leaseback transactions, for a sale to occur the transfer must meet the sale criteria under the new revenue standard, ASC 606. Entities will not be required to reassess transactions previously accounted under then existing guidance. Additionally, the ASU includes additional quantitative and qualitative disclosures required by lessees and lessors to help users better understand the amount, timing, and uncertainty of cash flows arising from leases. ASU No. 2016-02 is effective for fiscal years beginning after December 31, 2018, and interim periods within those fiscal years. Lessees and lessors are required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. The modified retrospective approach includes a number of optional practical expedients that entities may elect to apply as well as transition guidance specific to nonstandard leasing transactions. The Company is currently evaluating the provision of the ASU No. 2016-02 to determine the potential impact the new standard will have on the Company's consolidated financial statements. In March 2016 , the FASB issued ASU No. 2016-05, “Effect of Derivative Contract Novations on Existing Hedge Accounting Relationships”. This ASU clarifies that changes in the counterparty to a derivative instrument designated as a hedg e do not alone require it to be de-designated and therefore discontinue the application of hedge accounting. Companies are still required to evaluate whether it is probable that a counterparty will perform under the contract as part of the ongoing effectiveness assessment for hedge accounting. The new guidance is effective for annual periods beginning after December 15, 2016 and entities may adopt on a prospective or modified retrospective basis. The adoption of this pronouncement is not expected to have a material impact on the Company's consolidated financial statements. In March 2016, the FASB issued ASU No. 2016-06, “Contingent Put and Call Options in Debt Instruments” clarifying the assessment of whether contingent call (put) options that can accelerate the payment of principal on debt instruments are clearly and closely related to the economic characteristics and risks of their debt hosts, a criteria in assessing whether to bifurcate an embedded derivative. The new pronouncement clarifies the exercise contingency and the event triggering the contingency does not need to be evaluated in the clearly and closely analysis relative to interest rates or credit risks. Rather, the call or put would be evaluated as a derivative regardless of the exercise contingency. Further, if an entity is no longer required to bifurcate a put or call option per the new guidance, the entity has a one-time option to irrevocably elect to measure that debt instrument in its entirety at fair value with changes in fair value recognized in earnings. ASU No. 2016-06 is effective for annual periods beginning after December 15, 2016 and early adoption is permitted. The ASU should be applied using the modified retrospective basis to existing instruments as of the beginning of the annual period of adoption. The adoption of this pronouncement is not expected to have a material impact on the Company's consolidated financial statements. In March 2016, the FASB issued ASU No. 2016-07 “Simplifying the Transition to the Equity Method of Accounting” which eliminates the requirement to retroactively adjust an investment that becomes subject to the equity method of accounting as a result of an increase ownership interest or degree of influence. Alternatively, an investor entity adds the cost of acquiring the additional interest in the investee to the current basis of the investor’s previously held interest and adopts the equity method of accounting prospectively as of the qualifying date; no retroactive adjustment is required. Additionally, ASU No. 2016-07 specifies that when an available-for-sale equity security becomes qualified for the equity method of accounting, a company should recognize the unrealized holding gain or loss in accumulated other comprehensive income through earnings at the date the investment becomes qualified for use of the equity method. This guidance is effective for all entities for annual periods beginning after December 15, 2016, with early adoption permitted on a prospective basis. The adoption of this pronouncement is not expected to have a material impact on the Company's consolidated financial statements. In March 2016, the FASB issued ASU No. 2016-08 “Principal versus Agent Considerations (Reporting Revenue Gross versus Net)” to improve the usefulness and understandability of the guidance on principal versus agent considerations within the new revenue standard, ASC 606 “Revenue from Contracts with Customers”. The guidance clarified the following: (1) an entity determines if it is a principal or agent for each distinct good or service promised to the customer. If a contract includes multiple specified goods or services, an entity could be a principal for some and an agent for others: (2) for each specified good or service, an entity determines whether it is a good, a service, or a right to a good or service; (3) when another party is involved in providing goods or services to a customer, an entity that is a principal obtains control of: (a) a good from the other party and then transfers it to the customer; (b) the ability to direct that party to provide a service to the customer on the entity’s behalf; or (c) a good or service from the other party and combines it with other goods or services to provide to the customer; and (4) the purpose of the five indicators to determine whether an entity is a principal is to support or assist in the assessment of control. The indicators may be more or less relevant to the control assessment and one or more indicators may be more or less persuasive to the control assessment, depending on the facts and circumstances. The effective date and transition requirements mirror those of ASC 606 and similarly with that pronouncement, the Company is evaluating the provisions of ASU No. 2016-08, and will closely monitor developments and additional guidance to determine the potential impact on the consolidated financial statements. In March 2016, the FASB issued ASU No. 2016-09, “Improvement to Employee Share-Based Payment Accounting”. This ASU contains targeted amendments to the accounting for shared based payment transactions, including income tax consequences for awards, classification of awards as either equity or liabilities, and classification of activity on the statement of cash flows. Specifically, some of the requirements under the amendments include: (1) excess tax benefits and/or tax deficiencies, determined as the difference between compensation cost recognized for financial reporting purposes and the deduction for tax, be recognized in the income statement as income tax expense or benefit in the period in which they occur, removing historical equity treatment; (2) excess tax benefits are no longer separately classified as a financing activity but rather should be classified with other income tax cash flows as an operating activity on the statement of cash flows; (3) cash paid by an employer when withholding shares for tax withholding purposes should be classified as a financing activity. Additionally, regarding forfeitures, this guidance permits a company to make an entity-wide accounting policy election to either estimate the number of awards that are expected to vest (current GAAP) or account for forfeitures when they occur. If elected, the change to recognize forfeitures when they occur must be applied through a modified retrospective approach, with a cumulative effect adjustment recorded to opening retained earnings. ASU No. 2016-09 is effective for annual periods beginning after December 15, 2016. The Company is evaluating the provisions of ASU No. 2016-09, and will closely monitor developments and additional guidance to determine the potential impact on the consolidated financial statements.

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 March 31, 2016 , 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 historically 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 March 31, 2016 : AFS municipal bonds and obligations At March 31, 2016 , 3 of the total 118 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 the bonds in this portfolio carry minimal risk of default and the Company is appropriately compensated for that risk. The bonds are investment grade rated, and there were no material underlying credit downgrades during the quarter. All securities are performing. AFS residential mortgage-backed securities At March 31, 2016 , 55 out of the total 260 securities in the Company’s portfolios of AFS residential mortgage-backed securities were in unrealized loss positions. Aggregate unrealized losses represented 0.5% 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”) guarantee the contractual cash flows of all of the Company’s residential mortgage-backed securities. The securities are investment grade rated and there were no material underlying credit downgrades during the quarter. All securities are performing. AFS corporate bonds At March 31, 2016 , 6 out of 7 securities in the Company’s portfolio of AFS corporate bonds were in an unrealized loss position. The aggregate unrealized loss represents 5.2% of the amortized cost of bonds in unrealized loss positions. The Company reviews the financial strength of all of these bonds and has concluded that the amortized cost remains supported by the expected future cash flows of these securities. At March 31, 2016 , $1.5 million of the total unrealized losses was attributable to a $17.6 million investment. The Company evaluated this security, with a Level 2 fair value of $16.1 million , for potential other-than-temporary impairment (“OTTI”) at March 31, 2016 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 March 31, 2016, 2 out of the 3 securities in the Company’s portfolio of AFS trust preferred securities were in an unrealized loss position. Aggregate unrealized losses represented 0.9% of the amortized cost of these securities in an unrealized loss position. The Company’s evaluation of the present value of expected cash flows on these securities supports its conclusions about the recoverability of these securities’ amortized cost basis. These securities are 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 March 31, 2016 , 2 of the total 8 securities in the Company’s portfolio of other bonds and obligations were in unrealized loss positions. Aggregate unrealized losses represented 0.3% 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 March 31, 2016 , 11 out of the total 26 securities in the Company’s portfolio of marketable equity securities were in an unrealized loss position. The unrealized loss represented 10.0% of the amortized cost of the securities. The Company has the ability and intent to hold the securities until recovery of their cost basis and does not consider the securities other-than-temporarily impaired at March 31, 2016 . 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.

LOANS

LOANS	3 Months Ended

Receivables [Abstract]
LOANS	LOANS The Company’s loan portfolio is segregated into the following segments: commercial real estate, commercial and industrial, residential mortgage, and consumer. 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. Residential mortgage loans include classes for 1-4 family owner occupied and construction loans. Consumer loans include home equity, direct and indirect auto, and other. 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: March 31, 2016 December 31, 2015 (In thousands) Business Activities Loans Acquired Loans Total Business Activities Loans Acquired Loans Total Commercial real estate: Construction $ 216,745 $ 39,542 $ 256,287 $ 210,196 $ 43,474 $ 253,670 Single and multi-family 224,741 35,664 260,405 214,823 36,783 251,606 Other commercial real estate 1,251,087 332,288 1,583,375 1,209,008 345,483 1,554,491 Total commercial real estate 1,692,573 407,494 2,100,067 1,634,027 425,740 2,059,767 Commercial and industrial loans: Asset based lending 336,749 — 336,749 331,253 — 331,253 Other commercial and industrial loans 516,742 200,649 717,391 495,979 221,031 717,010 Total commercial and industrial loans 853,491 200,649 1,054,140 827,232 221,031 1,048,263 Total commercial loans 2,546,064 608,143 3,154,207 2,461,259 646,771 3,108,030 Residential mortgages: 1-4 family 1,414,338 317,626 1,731,964 1,454,233 332,747 1,786,980 Construction 20,319 1,339 21,658 26,704 1,351 28,055 Total residential mortgages 1,434,657 318,965 1,753,622 1,480,937 334,098 1,815,035 Consumer loans: Home equity 306,451 51,534 357,985 307,159 53,446 360,605 Auto and other 341,127 119,749 460,876 311,328 130,238 441,566 Total consumer loans 647,578 171,283 818,861 618,487 183,684 802,171 Total loans $ 4,628,299 $ 1,098,391 $ 5,726,690 $ 4,560,683 $ 1,164,553 $ 5,725,236 The carrying amount of the acquired loans at March 31, 2016 totaled $1.1 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 $18.3 million (and a note balance of $33.3 million). These loans are evaluated for impairment through the periodic reforecasting of expected cash flows. Loans considered not impaired at acquisition date had a carrying amount of $1.1 billion . At December 31, 2015 , acquired loans maintained a carrying value of $1.2 billion and purchased credit-impaired loans totaled $21.4 million (note balance of $40.2 million). Loans considered not impaired at acquisition date had a carrying amount of $1.1 billion .

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 identified during the three months ended March 31, 2016 and for the three months ended March 31, 2015, respectively. The table includes 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 three months ending March 31, 2016 were attributable to interest rate concessions, maturity date extensions, modified payment terms, reamortization, and accelerated maturity. The modifications for the three months ending March 31, 2015 were attributable to concessions granted as ordered by bankruptcy court, interest rate concessions and maturity date extensions.

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 credit problems 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 annually, 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 an eleven grade internal loan rating system for each of its acquired commercial real estate, construction and commercial loans 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 March 31, 2016 the allowance for loan losses related to acquired loans under ASC 310-30 and ASC 310-20 was $4.6 million using the above mentioned criteria.

Stockholders' Equity Note [Abstract]
CAPITAL RATIOS AND SHAREHOLDERS' EQUITY	CAPITAL RATIOS AND SHAREHOLDERS’ EQUITY The actual and required capital ratios were as follows: March 31, Regulatory December 31, Regulatory Company (consolidated) Total capital 11.8 % 10.0 % 11.9 % 10.0 % Common Equity Tier 1 Capital 9.7 6.5 9.8 6.5 Tier 1 capital 9.9 8.0 9.9 8.0 Tier 1 leverage 7.7 5.0 7.7 5.0 Bank Total capital 11.1 % 10.0 % 11.2 % 10.0 % Common Equity Tier 1 Capital 9.9 6.5 9.9 6.5 Tier 1 capital 9.9 8.0 9.9 8.0 Tier 1 leverage 7.7 5.0 7.7 5.0 At each date shown, the Company and the Bank met the conditions to be classified as “well capitalized” under the relevant regulatory framework. 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 table above. Effective January 1, 2015, the Company and the Bank became subject to the Basel III rule that requires the Company and the Bank to assess their Common Equity Tier 1 Capital to risk weighted assets and the Company and the Bank each exceed the minimum to be well capitalized. In addition, the final capital rules added a requirement to maintain a minimum conservation buffer, composed of Common equity tier 1 capital, of 2.5% of risk-weighted assets, to be phased in over three years and applied to the Common equity tier 1 risk-based capital ratio, the Tier 1 risk-based capital ratio and the Total risk-based capital ratio. Accordingly, banking organizations, on a fully phased in basis no later than January 1, 2019, must maintain a minimum Common equity tier 1 risk-based capital ratio of 7.0%, a minimum Tier 1 risk-based capital ratio of 8.5% and a minimum Total risk-based capital ratio of 10.5%. The required minimum conservation buffer began to be phased in incrementally, starting at 0.625% on January 1, 2016 and will increase to 1.25% on January 1, 2017, 1.875% on January 1, 2018 and 2.5% on January 1, 2019. The final capital rules impose restrictions on capital distributions and certain discretionary cash bonus payments if the minimum capital conservation buffer is not met. At March 31, 2016, the capital levels of both the Company and the Bank exceeded all regulatory capital requirements and their regulatory capital ratios were above the minimum levels required to be considered well capitalized for regulatory purposes. The capital levels of both the Company and the Bank at March 31, 2016 also exceeded the minimum capital requirements including the currently applicable capital conservation buffer of 0.625%.

DERIVATIVE INSTRUMENTS AND HEDG

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVE FINANCIAL INSTRUMENTS AND HEDGING ACTIVITIES	DERIVATIVE FINANCIAL INSTRUMENTS AND HEDGING ACTIVITIES As of March 31, 2016 , the Company held derivatives with a total notional amount of $1.5 billion . That amount included $300.0 million in 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 $1.2 billion and $48.9 million , respectively, which are not designated as hedges for accounting purposes and are therefore recorded at fair value. Economic hedges included interest rate swaps totaling $1.0 billion , risk participation agreements with dealer banks of $62.7 million , and $56.8 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 and Capital 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 March 31, 2016 . The Company pledged collateral to derivative counterparties in the form of cash totaling $7.5 million and securities with an amortized cost of $54.3 million and a fair value of $55.3 million as of March 31, 2016 . 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 two interest rate swap contracts with an aggregate notional value of $100 million and four forward-starting interest rate swap contracts with an aggregate notional value of $200 million as of March 31, 2016 . The four forward starting swaps will become effective in 2016. All have 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: Three Months Ended March 31, (In thousands) 2016 2015 Interest rate swaps on FHLBB borrowings: Unrealized (loss) recognized in accumulated other comprehensive loss $ (4,914 ) $ (3,901 ) Reclassification of unrealized loss from accumulated other comprehensive income to interest expense 408 — Net tax benefit (expense) on items recognized in accumulated other comprehensive income 1,808 1,572 Other comprehensive (loss) recorded in accumulated other comprehensive income, net of reclassification adjustments and tax effects $ (2,698 ) $ (2,329 ) Net interest expense recognized in interest expense on junior subordinated notes $ 408 $ — Hedge ineffectiveness on interest rate swaps designated as cash flow hedges was immaterial to the Company’s financial statements during the three months ended March 31, 2016 and 2015 . 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 twelve months, the Company anticipates reclassification of approximately $5.4 million . Economic hedges As of March 31, 2016 , 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 $(74.3) thousand of March 31, 2016 . 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 gets paid 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. Changes in fair value are recorded in current period earnings. 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 originated 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 sale 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 sale 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 TBA 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: Three Months Ended March 31, (In thousands) 2016 2015 Economic hedges Interest rate swap on industrial revenue bond: Unrealized (loss) recognized in other non-interest income $ (539 ) $ (271 ) Interest rate swaps on loans with commercial loan customers: Unrealized (loss) recognized in other non-interest income (13,597 ) (3,114 ) Reverse interest rate swaps on loans with commercial loan customers: Unrealized gain recognized in other non-interest income 13,597 3,114 (Unfavorable) Favorable change in credit valuation adjustment recognized in other non-interest income (61 ) 1 Risk Participation Agreements: Unrealized gain/(loss) recognized in other non-interest income 83 (9 ) Forward Commitments: Unrealized (loss) recognized in other non-interest income (447 ) (388 ) Realized (loss) in other non-interest income (383 ) (91 ) Non-hedging derivatives Interest rate lock commitments Unrealized gain recognized in other non-interest income $ 802 $ 977 Realized gain in other non-interest income 849 755 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 $30.7 million and $17.1 million as of March 31, 2016 and December 31, 2015 , respectively. The Company had net liability positions with its financial institution counterparties totaling $46.7 million and $28.2 million as of March 31, 2016 and December 31, 2015 , respectively. At March 31, 2016 , the Company did not have a net liability position with its commercial banking counterparties. The collateral posted by the Company that covered liability positions was $46.7 million and $28.2 million as of March 31, 2016 and December 31, 2015 , respectively. The following table presents the assets and liabilities subject to an enforceable master netting arrangement as of March 31, 2016 and December 31, 2015 : Offsetting of Financial Assets and Derivative Assets Gross Amounts of Gross Amounts Offset in the Net Amounts of Assets Presented in the Gross Amounts Not Offset in the Statements of Condition Recognized Statements of Statements of Financial Cash Collateral (in thousands) Assets Condition Condition Instruments Received Net Amount March 31, 2016 Interest Rate Swap Agreements: Institutional counterparties $ 106 $ — $ 106 $ — $ — $ 106 Commercial counterparties 30,666 — 30,666 — — 30,666 Total $ 30,772 $ — $ 30,772 $ — $ — $ 30,772 Offsetting of Financial Liabilities and Derivative Liabilities Gross Amounts of Gross Amounts Offset in the Net Amounts of Liabilities Presented in the Gross Amounts Not Offset in the Statements of Condition Recognized Statements of Statements of Financial Cash Collateral (in thousands) Liabilities Condition Condition Instruments Pledged Net Amount March 31, 2016 Interest Rate Swap Agreements: Institutional counterparties $ (46,754 ) $ 39 $ (46,715 ) $ 39,465 $ 7,250 $ — Commercial counterparties — — — — — — Total $ (46,754 ) $ 39 $ (46,715 ) $ 39,465 $ 7,250 $ — Offsetting of Financial Assets and Derivative Assets Gross Amounts of Gross Amounts Offset in the Net Amounts of Assets Presented in the Gross Amounts Not Offset in the Statements of Condition Recognized Statements of Statements of Financial Cash Collateral (in thousands) Assets Condition Condition Instruments Received Net Amount 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 Amounts of Gross Amounts Offset in the Net Amounts of Liabilities Presented in the Gross Amounts Not Offset in the Statements of Condition Recognized Statements of Statements of Financial Cash Collateral (in thousands) Liabilities Condition Condition Instruments Pledged Net Amount 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 $ —

Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS	FAIR VALUE MEASUREMENTS A description of the valuation methodologies used for assets and liabilities 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 The following table summarizes financial assets and financial liabilities measured at fair value on a recurring basis as of March 31, 2016 and December 31, 2015 , segregated by the level of the valuation inputs within the fair value hierarchy utilized to measure fair value. March 31, 2016 Level 1 Level 2 Level 3 Total (In thousands) Inputs Inputs Inputs Fair Value Trading security $ — $ — $ 14,474 $ 14,474 Available-for-sale securities: Municipal bonds and obligations — 104,742 — 104,742 Government guaranteed residential mortgage-backed securities — 66,089 — 66,089 Government-sponsored residential mortgage-backed securities — 898,745 — 898,745 Corporate bonds — 41,002 — 41,002 Trust preferred securities — 11,617 — 11,617 Other bonds and obligations — 3,203 — 3,203 Marketable equity securities 44,697 1,439 — 46,136 Loans held for sale (1) — 14,789 — 14,789 Derivative assets — 30,666 802 31,468 Derivative liabilities 304 46,610 143 47,057 (1) Loans held for sale excludes $1.1 million of loans for sale held shown on the balance sheet that are held at lower of cost or market. December 31, 2015 Level 1 Level 2 Level 3 Total (In thousands) Inputs Inputs Inputs Fair Value 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 During the three months ended March 31, 2016 , the Company had one transfer of $708 thousand in marketable equity securities from Level 3 to Level 2 based on a change in valuation technique driven by the availability of market data. There were no transfers between levels during the three months ended March 31, 2015 . 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. Loans held for sale. The Company elected the fair value option for all loans held for sale (HFS) 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 Fair Value March 31, 2016 Aggregate Aggregate Less Aggregate (In thousands) Fair Value Unpaid Principal Unpaid Principal Loans Held for Sale (1) $ 14,789 $ 14,297 $ 492 (1) Loans held for sale excludes $1.1 million of loans for sale held shown on the balance sheet that are held at lower of cost or market. Aggregate Fair Value December 31, 2015 Aggregate Aggregate Less Aggregate (In thousands) Fair Value Unpaid Principal Unpaid Principal Loans Held for Sale $ 13,191 $ 12,914 $ 277 The changes in fair value of loans held for sale for the three months ended March 31, 2016 and March 31, 2015, were gains of $215 thousand and $214 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 March 31, 2016 , 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, 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 the hedging instrument, 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 commitments are classified as Level 3 measurements. The table below presents the changes in Level 3 assets and liabilities that were measured at fair value on a recurring basis for the three months ended March 31, 2016 and 2015 .

There were no Level 1 or Level 2 nonrecurring fair value measurements for the periods ended March 31, 2016 and December 31, 2015 . 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, nonrecurring fair value measurement adjustments that relate to real estate collateral 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.

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. FHLB bank stock and restricted 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 the cash flows of the loans discounted over their respective loan origination rates. The origination rates are adjusted for substandard and special mention loans to factor the impact of declines in the loan’s credit standing. 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. The fair value of borrowed funds is estimated by discounting the future cash flows using market rates for similar borrowings. Such funds include all categories of debt and debentures in the table above. Subordinated borrowings. The Company utilizes a pricing service along with internal models to estimate the valuation of its junior subordinated debentures. The junior subordinated debentures re-price every ninety days. Off-balance-sheet financial instruments. Off-balance-sheet financial instruments include standby letters of credit and other financial guarantees and commitments considered immaterial to the Company’s financial statements.

Subsequent Events [Abstract]
SUBSEQUENT EVENTS	SUBSEQUENT EVENTS On April 29, 2016, the Company acquired the business model of 44 Business Capital, LLC, as well as certain small business loans and other assets of Parke Bank's SBA 7(a) loan program operations. The transaction was completed for aggregate cash and stock consideration of $56.9 million and $1.2 million , respectively. Approximately 45 thousand shares representing the aggregate stock consideration were issued to the four principals of a member entity of 44 Business Capital, LLC. As a result of the proximity of the closing of the transaction to the date these consolidated financial statements are available to be issued, the Company is still evaluating the estimated fair value of the assets acquired. Accordingly, the amount of any goodwill and other intangible assets to be recognized in connection with this transaction is also yet to be determined. This purchase and assumption agreement had no significant effect on the Company’s financial statements for the periods presented.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	BASIS OF PRESENTATION The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and contain all adjustments, consisting solely of normal, recurring adjustments, necessary for a fair presentation of results for such periods. In addition, these interim financial statements have been prepared in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X, and accordingly, certain information and footnote disclosures normally included in financial statements prepared according to U.S. GAAP have been omitted. The results for any interim period are not necessarily indicative of results for the full year. These consolidated financial statements should be read in conjunction with the audited financial statements and note disclosures for Berkshire Hills Bancorp, Inc. (the “Company”) previously filed with the Securities and Exchange Commission in the Company’s Annual Report on Form 10-K for the year ended December 31, 2015.
Reclassifications	Reclassifications Certain items in prior financial statements have been reclassified to conform to the current presentation.
Recently Adopted Accounting Principles and Future Application of Accounting Pronouncements	Recently Adopted Accounting Principles 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 Company adopted the provisions of ASU No. 2015-02 effective January 1, 2016, which did not have a material effect on the Company's consolidated financial statements. See Note 7. Borrowed Funds to the Consolidated Financial statements for more information. In April 2015, the FASB issued ASU No. 2015-03, “Simplifying the Presentation of Debt Issuance Costs.” This ASU requires that debt issuance costs, not including those related to line of credit arrangements, 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 Company adopted the provisions of ASU No. 2015-03 effective January 1, 2016, which did not have a material effect on the Company's 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 Company adopted the provisions of ASU No. 2015-05 effective January 1, 2016, which did not have a material effect on the Company's 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 Company adopted the provisions of ASU No. 2015-16 effective January 1, 2016, which did not have a material effect on the Company's 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), issuing ASU 2015-14 “Revenue from Contracts with Customers -Deferral of the Effective Date.” 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 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. In February 2016, the FASB issued ASU No. 2016-02, “Leases”. The new pronouncement improves the transparency and comparability of financial reporting around leasing transactions and more closely aligns accounting for leases with the recently issued International Financial Reporting Standard. The pronouncement affects all entities that are participants to leasing agreements. From a lessee accounting perspective, the ASU requires a lessee to recognize assets and liabilities on the balance sheet for operating leases and changes many key definitions, including the definition of a lease. The ASU includes a short-term lease exception for leases with a term of twelve months or less, in which a lessee can make an accounting policy election not to recognize lease assets and lease liabilities. Lessees will continue to differentiate between finance leases (previously referred to as capital leases) and operating leases, using classification criteria that are substantially similar to the previous guidance. For lessees, the recognition, measurement, and presentation of expenses and cash flows arising from a lease have not significantly changed from previous GAAP. From a lessor accounting perspective, the guidance is largely unchanged, except for targeted improvements to align with new terminology under lessee accounting and with the updated revenue recognition guidance in Topic 606. For sale-leaseback transactions, for a sale to occur the transfer must meet the sale criteria under the new revenue standard, ASC 606. Entities will not be required to reassess transactions previously accounted under then existing guidance. Additionally, the ASU includes additional quantitative and qualitative disclosures required by lessees and lessors to help users better understand the amount, timing, and uncertainty of cash flows arising from leases. ASU No. 2016-02 is effective for fiscal years beginning after December 31, 2018, and interim periods within those fiscal years. Lessees and lessors are required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. The modified retrospective approach includes a number of optional practical expedients that entities may elect to apply as well as transition guidance specific to nonstandard leasing transactions. The Company is currently evaluating the provision of the ASU No. 2016-02 to determine the potential impact the new standard will have on the Company's consolidated financial statements. In March 2016 , the FASB issued ASU No. 2016-05, “Effect of Derivative Contract Novations on Existing Hedge Accounting Relationships”. This ASU clarifies that changes in the counterparty to a derivative instrument designated as a hedg e do not alone require it to be de-designated and therefore discontinue the application of hedge accounting. Companies are still required to evaluate whether it is probable that a counterparty will perform under the contract as part of the ongoing effectiveness assessment for hedge accounting. The new guidance is effective for annual periods beginning after December 15, 2016 and entities may adopt on a prospective or modified retrospective basis. The adoption of this pronouncement is not expected to have a material impact on the Company's consolidated financial statements. In March 2016, the FASB issued ASU No. 2016-06, “Contingent Put and Call Options in Debt Instruments” clarifying the assessment of whether contingent call (put) options that can accelerate the payment of principal on debt instruments are clearly and closely related to the economic characteristics and risks of their debt hosts, a criteria in assessing whether to bifurcate an embedded derivative. The new pronouncement clarifies the exercise contingency and the event triggering the contingency does not need to be evaluated in the clearly and closely analysis relative to interest rates or credit risks. Rather, the call or put would be evaluated as a derivative regardless of the exercise contingency. Further, if an entity is no longer required to bifurcate a put or call option per the new guidance, the entity has a one-time option to irrevocably elect to measure that debt instrument in its entirety at fair value with changes in fair value recognized in earnings. ASU No. 2016-06 is effective for annual periods beginning after December 15, 2016 and early adoption is permitted. The ASU should be applied using the modified retrospective basis to existing instruments as of the beginning of the annual period of adoption. The adoption of this pronouncement is not expected to have a material impact on the Company's consolidated financial statements. In March 2016, the FASB issued ASU No. 2016-07 “Simplifying the Transition to the Equity Method of Accounting” which eliminates the requirement to retroactively adjust an investment that becomes subject to the equity method of accounting as a result of an increase ownership interest or degree of influence. Alternatively, an investor entity adds the cost of acquiring the additional interest in the investee to the current basis of the investor’s previously held interest and adopts the equity method of accounting prospectively as of the qualifying date; no retroactive adjustment is required. Additionally, ASU No. 2016-07 specifies that when an available-for-sale equity security becomes qualified for the equity method of accounting, a company should recognize the unrealized holding gain or loss in accumulated other comprehensive income through earnings at the date the investment becomes qualified for use of the equity method. This guidance is effective for all entities for annual periods beginning after December 15, 2016, with early adoption permitted on a prospective basis. The adoption of this pronouncement is not expected to have a material impact on the Company's consolidated financial statements. In March 2016, the FASB issued ASU No. 2016-08 “Principal versus Agent Considerations (Reporting Revenue Gross versus Net)” to improve the usefulness and understandability of the guidance on principal versus agent considerations within the new revenue standard, ASC 606 “Revenue from Contracts with Customers”. The guidance clarified the following: (1) an entity determines if it is a principal or agent for each distinct good or service promised to the customer. If a contract includes multiple specified goods or services, an entity could be a principal for some and an agent for others: (2) for each specified good or service, an entity determines whether it is a good, a service, or a right to a good or service; (3) when another party is involved in providing goods or services to a customer, an entity that is a principal obtains control of: (a) a good from the other party and then transfers it to the customer; (b) the ability to direct that party to provide a service to the customer on the entity’s behalf; or (c) a good or service from the other party and combines it with other goods or services to provide to the customer; and (4) the purpose of the five indicators to determine whether an entity is a principal is to support or assist in the assessment of control. The indicators may be more or less relevant to the control assessment and one or more indicators may be more or less persuasive to the control assessment, depending on the facts and circumstances. The effective date and transition requirements mirror those of ASC 606 and similarly with that pronouncement, the Company is evaluating the provisions of ASU No. 2016-08, and will closely monitor developments and additional guidance to determine the potential impact on the consolidated financial statements. In March 2016, the FASB issued ASU No. 2016-09, “Improvement to Employee Share-Based Payment Accounting”. This ASU contains targeted amendments to the accounting for shared based payment transactions, including income tax consequences for awards, classification of awards as either equity or liabilities, and classification of activity on the statement of cash flows. Specifically, some of the requirements under the amendments include: (1) excess tax benefits and/or tax deficiencies, determined as the difference between compensation cost recognized for financial reporting purposes and the deduction for tax, be recognized in the income statement as income tax expense or benefit in the period in which they occur, removing historical equity treatment; (2) excess tax benefits are no longer separately classified as a financing activity but rather should be classified with other income tax cash flows as an operating activity on the statement of cash flows; (3) cash paid by an employer when withholding shares for tax withholding purposes should be classified as a financing activity. Additionally, regarding forfeitures, this guidance permits a company to make an entity-wide accounting policy election to either estimate the number of awards that are expected to vest (current GAAP) or account for forfeitures when they occur. If elected, the change to recognize forfeitures when they occur must be applied through a modified retrospective approach, with a cumulative effect adjustment recorded to opening retained earnings. ASU No. 2016-09 is effective for annual periods beginning after December 15, 2016. The Company is evaluating the provisions of ASU No. 2016-09, and will closely monitor developments and additional guidance to determine the potential impact on the consolidated financial statements.
