Earnings Per Share [Abstract]
EARNINGS PER SHARE	EPS The following is an analysis of basic and diluted EPS, reflecting the application of the two-class method, as described below: Three Months Ended Nine Months Ended 2015 2014 2015 2014 Net income $ 6,456 $ 6,451 $ 19,260 $ 18,482 Dividends and undistributed earnings allocated to participating securities (1) (21 ) (20 ) (61 ) (57 ) Net income available to common shareholders $ 6,435 $ 6,431 $ 19,199 $ 18,425 Weighted-average common shares outstanding for basic EPS 7,453,222 7,421,592 7,443,543 7,459,972 Dilutive effect of stock-based awards (2) 23,817 18,356 20,941 19,355 Weighted-average common and potential common shares for diluted EPS 7,477,039 7,439,948 7,464,484 7,479,327 Earnings per common share: Basic EPS $ 0.86 $ 0.87 $ 2.58 $ 2.47 Diluted EPS $ 0.86 $ 0.86 $ 2.57 $ 2.46 Awards excluded from the calculation of diluted EPS (3) : Stock options 13,750 30,750 16,250 14,750 (1) Represents dividends paid and undistributed earnings allocated to nonvested stock-based awards that contain non-forfeitable rights to dividends. (2) Represents the effect of the assumed exercise of stock options, vesting of restricted shares, vesting of restricted stock units, and vesting of LTIP awards that have met the performance criteria, as applicable, utilizing the treasury stock method. (3) Represents stock-based awards not included in the computation of potential common shares for purposes of calculating diluted EPS as the exercise prices were greater than the average market price of the Company's common stock. Nonvested stock-based payment awards that contain non-forfeitable rights to dividends are participating securities and are included in the computation of EPS pursuant to the two-class method. The two-class method is an earnings allocation formula that determines EPS for each class of common stock and participating security according to dividends declared (or accumulated) and participation rights in undistributed earnings. Certain of the Company’s nonvested stock-based awards qualify as participating securities. Net income is allocated between the common stock and participating securities pursuant to the two-class method. Basic EPS is computed by dividing net income available to common shareholders by the weighted average number of common shares outstanding during the period, excluding participating nonvested stock-based awards. Diluted EPS is computed in a similar manner, except that the denominator is increased to include the number of additional common shares that would have been outstanding if potentially dilutive common shares were issued using the treasury stock method.

Net unrealized losses on AFS securities at December 31, 2014 included in AOCI amounted to $319,000 , net of a deferred tax benefit of $172,000 . During the first nine months of 2015, the Company purchased investment securities totaling $136.7 million . The Company designated $81.3 million as AFS securities and $55.4 million as HTM securities. Impaired Securities Management periodically reviews the Company’s investment portfolio to determine the cause, magnitude and duration of declines in the fair value of each security. Thorough evaluations of the causes of the unrealized losses are performed to determine whether the impairment is temporary or other-than-temporary in nature. Considerations such as the ability of the securities to meet cash flow requirements, levels of credit enhancements, risk of curtailment, recoverability of invested amount over a reasonable period of time, and the length of time the security is in a loss position, for example, are applied in determining OTTI. Once a decline in value is determined to be other-than-temporary, the value of the security is permanently reduced and a corresponding charge to earnings is recognized. The following table presents the estimated fair values and gross unrealized losses of investment securities that were in a continuous loss position at September 30, 2015 and December 31, 2014 , by length of time that individual securities in each category have been in a continuous loss position: Less Than 12 Months 12 Months or More Total Fair Value Unrealized Losses Fair Value Unrealized Losses Fair Value Unrealized Losses September 30, 2015 AFS Securities: Mortgage-backed securities issued or guaranteed by U.S. government-sponsored enterprises $ 53,164 $ (395 ) $ 57,721 $ (996 ) $ 110,885 $ (1,391 ) Collateralized mortgage obligations issued or guaranteed by U.S. government-sponsored enterprises 12,183 (188 ) 145,289 (2,519 ) 157,472 (2,707 ) Total AFS securities $ 65,347 $ (583 ) $ 203,010 $ (3,515 ) $ 268,357 $ (4,098 ) HTM Securities: Obligations of states and political subdivisions $ 12,388 $ (101 ) $ — $ — $ 12,388 $ (101 ) Total HTM securities $ 12,388 $ (101 ) $ — $ — $ 12,388 $ (101 ) December 31, 2014 AFS Securities: Mortgage-backed securities issued or guaranteed by U.S. government-sponsored enterprises $ 42,856 $ (171 ) $ 125,439 $ (1,834 ) $ 168,295 $ (2,005 ) Collateralized mortgage obligations issued or guaranteed by U.S. government-sponsored enterprises 75,723 (432 ) 182,512 (5,479 ) 258,235 (5,911 ) Private issue collateralized mortgage obligations 1,785 (8 ) — — 1,785 (8 ) Total AFS securities $ 120,364 $ (611 ) $ 307,951 $ (7,313 ) $ 428,315 $ (7,924 ) HTM Securities: Obligations of states and political subdivisions $ 5,756 $ (19 ) $ — $ — $ 5,756 $ (19 ) Total HTM securities $ 5,756 $ (19 ) $ — $ — $ 5,756 $ (19 ) At September 30, 2015 , the Company held 73 investment securities with a fair value of $280.7 million with unrealized losses totaling $ 4.2 million that are considered temporary. Of these, the Company had 34 MBS and CMO investments with a fair value of $ 203.0 million that have been in an unrealized loss position for 12 months or more. The decline in the fair value of securities is reflective of current interest rates in excess of the yield received on investments and is not indicative of an overall credit deterioration or other factors with the Company's investment portfolio. At September 30, 2015, gross unrealized losses on the Company's AFS and HTM securities were 1% of amortized cost. The Company has the intent and ability to retain its investment securities in an unrealized loss position at September 30, 2015 until the decline in value has recovered. Sale of Securities The following table details the Company’s sales of AFS securities for the period indicated below: Three Months Ended September 30, Nine Months Ended September 30, 2015 2014 2015 2014 Proceeds from sales of securities $ 12,426 $ — $ 12,426 $ 25,695 Gross realized gains 221 — 221 451 Gross realized losses (217 ) — (217 ) — For the three months ended September 30, 2015 , the Company sold certain AFS securities with total carrying value of $12.4 million and recorded net gains on the sale of AFS securities of $4,000 within non-interest income in the consolidated statements of income.

The Company recorded a net gain of $4,000 from the sale of its Non-Agency and MBS investments. The Company had previously recorded OTTI on its Non-Agency investments of $204,000 . For the three months ended September 30, 2014 , the Company did no t sell any investment securities. For the nine months ended September 30, 2015 , the Company sold certain AFS securities with total carrying value of $12.4 million and recorded net gains on sale of AFS securities of $4,000 within non-interest income in the consolidated statements of income.

Loans and Leases Receivable Disclosure [Abstract]
LOANS AND ALLOWANCE FOR LOAN LOSSES	LOANS AND ALLOWANCE FOR LOAN LOSSES The composition of the Company’s loan portfolio, excluding residential loans held for sale, at September 30, 2015 and December 31, 2014 was as follows: September 30, December 31, Residential real estate $ 583,424 $ 585,996 Commercial real estate 690,935 640,661 Commercial 258,105 257,515 Home equity 281,492 271,709 Consumer 16,535 17,257 Net deferred fees (348 ) (528 ) Total $ 1,830,143 $ 1,772,610 The Company’s lending activities are primarily conducted in Maine, and its footprint continues to expand into other New England states, including New Hampshire and Massachusetts. The Company originates single family and multi-family residential loans, commercial real estate loans, business loans, municipal loans and a variety of consumer loans. In addition, the Company makes loans for the construction of residential homes, multi-family properties and commercial real estate properties. The ability and willingness of borrowers to honor their repayment commitments is generally dependent on the level of overall economic activity within the geographic area and the general economy. The ALL is management’s best estimate of the inherent risk of loss in the Company’s loan portfolio as of the consolidated statement of condition date. Management makes various assumptions and judgments about the collectability of the loan portfolio and provides an allowance for potential losses based on a number of factors including historical losses. If those assumptions are incorrect, the ALL may not be sufficient to cover losses and may cause an increase in the allowance in the future. Among the factors that could affect the Company’s ability to collect loans and require an increase to the allowance in the future are: (i) financial condition of borrowers; (ii) real estate market changes; (iii) state, regional, and national economic conditions; and (iv) a requirement by federal and state regulators to increase the provision for loan losses or recognize additional charge-offs. There were no significant changes in the Company's ALL methodology during the nine months ended September 30, 2015 . The board of directors monitors credit risk through the Directors' Loan Review Committee, which reviews large credit exposures, monitors the external loan review reports, reviews the lending authority for individual loan officers when required, and has approval authority and responsibility for all matters regarding the loan policy and other credit-related policies, including reviewing and monitoring asset quality trends, concentration levels, and the ALL methodology. The Corporate Risk Management Group and the Credit Risk Policy Committee oversee the Company's systems and procedures to monitor the credit quality of its loan portfolio, conduct a loan review program, maintain the integrity of the loan rating system, determine the adequacy of the ALL and support the oversight efforts of the Directors' Loan Review Committee and the board of directors. The Company's practice is to proactively manage the portfolio such that management can identify problem credits early, assess and implement effective work-out strategies, and take charge-offs as promptly as practical. In addition, the Company continuously reassesses its underwriting standards in response to credit risk posed by changes in economic conditions. For purposes of determining the ALL, the Company disaggregates its loans into portfolio segments, which include residential real estate, commercial real estate, commercial, home equity, and consumer. Each portfolio segment possesses unique risk characteristics that are considered when determining the appropriate level of allowance. These risk characteristics unique to each portfolio segment include: Residential Real Estate . Residential real estate loans held in the Company's loan portfolio are made to borrowers who demonstrate the ability to make scheduled payments with full consideration to underwriting factors. Borrower qualifications include favorable credit history combined with supportive income requirements and combined loan-to-value ratios within established policy guidelines. Collateral consists of mortgage liens on one- to four-family residential properties. Commercial Real Estate. Commercial real estate loans consist of mortgage loans to finance investments in real property such as multi-family residential, commercial/retail, office, industrial, hotels, educational, health care facilities and other specific use properties. Commercial real estate loans are typically written with amortizing payment structures. Collateral values are determined based upon appraisals and evaluations in accordance with established policy guidelines. Loan-to-value ratios at origination are governed by established policy and regulatory guidelines. Commercial real estate loans are primarily paid by the cash flow generated from the real property, such as operating leases, rents, or other operating cash flows from the borrower. Commercial. Commercial loans consist of revolving and term loan obligations extended to business and corporate enterprises for the purpose of financing working capital and/or capital investment. Collateral generally consists of pledges of business assets including, but not limited to, accounts receivable, inventory, plant & equipment, or real estate, if applicable. Commercial loans are primarily paid by the operating cash flow of the borrower. Commercial loans may be secured or unsecured. Home Equity. Home equity loans and lines are made to qualified individuals for legitimate purposes secured by senior or junior mortgage liens on owner-occupied one- to four-family homes, condominiums, or vacation homes. The home equity loan has a fixed rate and is billed as equal payments comprised of principal and interest. The home equity line of credit has a variable rate and is billed as interest-only payments during the draw period. At the end of the draw period, the home equity line of credit is billed as a percentage of the principal balance plus all accrued interest. Borrower qualifications include favorable credit history combined with supportive income requirements and combined loan-to-value ratios within established policy guidelines. Consumer. Consumer loan products including personal lines of credit and amortizing loans made to qualified individuals for various purposes such as education, auto loans, debt consolidation, personal expenses or overdraft protection. Borrower qualifications include favorable credit history combined with supportive income and collateral requirements within established policy guidelines. Consumer loans may be secured or unsecured.

The reserve for unfunded commitments is presented within accrued interest and other liabilities on the consolidated statements of condition. At September 30, 2015 and 2014, and December 31, 2014, the reserve for unfunded commitments was $24,000 , $21,000 and $17,000 , respectively. The following table reconciles the three and nine months ended September 30, 2015 and 2014, and year ended December 31, 2014 provision for loan losses to the provision for credit losses as presented on the consolidated statement of income: Three Months Ended September 30, Nine Months Ended Year Ended December 31, 2015 2014 2015 2014 2014 Provision for loan losses $ 281 $ 534 $ 972 $ 1,675 $ 2,224 Change in reserve for unfunded commitments (2 ) 5 7 — (4 ) Provision for credit losses $ 279 $ 539 $ 979 $ 1,675 $ 2,220 The Company focuses on maintaining a well-balanced and diversified loan portfolio. Despite such efforts, it is recognized that credit concentrations may occasionally emerge as a result of economic conditions, changes in local demand, natural loan growth and runoff. To ensure that credit concentrations can be effectively identified, all commercial and commercial real estate loans are assigned Standard Industrial Classification codes, North American Industry Classification System codes, and state and county codes. Shifts in portfolio concentrations are monitored by the Corporate Risk Management Group. As of September 30, 2015 , the non-residential building operators industry exposure was 11% of the Company's total loan portfolio and 28% of the total commercial real estate portfolio. There were no other industry exposures exceeding 10% of the Company's total loan portfolio as of September 30, 2015. To further identify loans with similar risk profiles, the Company categorizes each portfolio segment into classes by credit risk characteristic and applies a credit quality indicator to each portfolio segment. The indicators for commercial, commercial real estate and residential real estate loans are represented by Grades 1 through 10 as outlined below. In general, risk ratings are adjusted periodically throughout the year as updated analysis and review warrants. This process may include, but is not limited to, annual credit and loan reviews, periodic reviews of loan performance metrics, such as delinquency rates, and quarterly reviews of adversely risk rated loans. The Company uses the following definitions when assessing grades for the purpose of evaluating the risk and adequacy of the ALL: • Grade 1 through 6 — Grades 1 through 6 represent groups of loans that are not subject to adverse criticism as defined in regulatory guidance. Loans in these groups exhibit characteristics that represent low to moderate risks, which is measured using a variety of credit risk criteria, such as cash flow coverage, debt service coverage, balance sheet leverage, liquidity, management experience, industry position, prevailing economic conditions, support from secondary sources of repayment and other credit factors that may be relevant to a specific loan. In general, these loans are supported by properly margined collateral and guarantees of principal parties. • Grade 7 — Loans with potential weakness (Special Mention). Loans in this category are currently protected based on collateral and repayment capacity and do not constitute undesirable credit risk, but have potential weakness that may result in deterioration of the repayment process at some future date. This classification is used if a negative trend is evident in the obligor’s financial situation. Special mention loans do not sufficiently expose the Company to warrant adverse classification. • Grade 8 — Loans with definite weakness (Substandard). Loans classified as substandard are inadequately protected by the current sound worth and paying capacity of the obligor or by collateral pledged. Borrowers experience difficulty in meeting debt repayment requirements. Deterioration is sufficient to cause the Company to look to the sale of collateral. • Grade 9 — Loans with potential loss (Doubtful). Loans classified as doubtful have all the weaknesses inherent in the substandard grade with the added characteristic that the weaknesses make collection or liquidation of the loan in full highly questionable and improbable. The possibility of some loss is extremely high, but because of specific pending factors that may work to the advantage and strengthening of the asset, its classification as an estimated loss is deferred until its more exact status may be determined. • Grade 10 — Loans with definite loss (Loss). Loans classified as loss are considered uncollectible. The loss classification does not mean that the asset has absolutely no recovery or salvage value, but rather that it is not practical or desirable to defer writing off the asset because recovery and collection time may be protracted. Asset quality indicators are periodically reassessed to appropriately reflect the risk composition of the Company’s loan portfolio. Home equity and consumer loans are not individually risk rated, but rather analyzed as groups taking into account delinquency rates and other economic conditions which may affect the ability of borrowers to meet debt service requirements, including interest rates and energy costs. Performing loans include loans that are current and loans that are past due less than 90 days. Loans that are past due over 90 days and non-accrual loans, including TDRs, are considered non-performing. The following table summarizes credit risk exposure indicators by portfolio segment as of the following dates: Residential Real Estate Commercial Real Estate Commercial Home Equity Consumer Total September 30, 2015 Pass (Grades 1-6) $ 573,229 $ 647,831 $ 247,817 $ — $ — $ 1,468,877 Performing — — — 280,455 16,329 296,784 Special Mention (Grade 7) 2,599 12,689 5,881 — — 21,169 Substandard (Grade 8) 7,248 30,415 4,407 — — 42,070 Non-performing — — — 1,037 206 1,243 Total $ 583,076 $ 690,935 $ 258,105 $ 281,492 $ 16,535 $ 1,830,143 December 31, 2014 Pass (Grades 1-6) $ 572,589 $ 606,387 $ 244,930 $ — $ — $ 1,423,906 Performing — — — 269,968 16,986 286,954 Special Mention (Grade 7) 3,579 4,690 6,023 — — 14,292 Substandard (Grade 8) 9,300 29,584 6,562 — — 45,446 Non-performing — — — 1,741 271 2,012 Total $ 585,468 $ 640,661 $ 257,515 $ 271,709 $ 17,257 $ 1,772,610 The Company closely monitors the performance of its loan portfolio. A loan is placed on non-accrual status when the financial condition of the borrower is deteriorating, payment in full of both principal and interest is not expected as scheduled or principal or interest has been in default for 90 days or more. Exceptions may be made if the asset is well-secured by collateral sufficient to satisfy both the principal and accrued interest in full and collection is reasonably assured. When one loan to a borrower is placed on non-accrual status, all other loans to the borrower are re-evaluated to determine if they should also be placed on non-accrual status. All previously accrued and unpaid interest is reversed at this time. A loan may be returned to accrual status when collection of principal and interest is assured and the borrower has demonstrated timely payments of principal and interest for a reasonable period. Unsecured loans, however, are not normally placed on non-accrual status because they are charged-off once their collectability is in doubt. The following is a loan aging analysis by portfolio segment (including loans past due over 90 days and non-accrual loans) and a summary of non-accrual loans, which include TDRs, and loans past due over 90 days and accruing as of the following dates: 30-59 Days Past Due 60-89 Days Past Due Greater than 90 Days Total Past Due Current Total Loans Outstanding Loans > 90 Days Past Due and Accruing Non-Accrual Loans September 30, 2015 Residential real estate $ 977 $ 303 $ 3,199 $ 4,479 $ 578,597 $ 583,076 $ — $ 4,149 Commercial real estate 1,997 64 1,964 4,025 686,910 690,935 — 3,384 Commercial 669 51 1,107 1,827 256,278 258,105 — 1,383 Home equity 211 35 811 1,057 280,435 281,492 — 1,037 Consumer 55 25 183 263 16,272 16,535 — 206 Total $ 3,909 $ 478 $ 7,264 $ 11,651 $ 1,818,492 $ 1,830,143 $ — $ 10,159 December 31, 2014 Residential real estate $ 1,206 $ 426 $ 4,531 $ 6,163 $ 579,305 $ 585,468 $ — $ 6,056 Commercial real estate 1,696 — 3,791 5,487 635,174 640,661 — 7,043 Commercial 456 269 1,139 1,864 255,651 257,515 — 1,529 Home equity 889 88 1,129 2,106 269,603 271,709 — 1,741 Consumer 28 — 254 282 16,975 17,257 — 271 Total $ 4,275 $ 783 $ 10,844 $ 15,902 $ 1,756,708 $ 1,772,610 $ — $ 16,640 Interest income that would have been recognized if loans on non-accrual status had been current in accordance with their original terms was $103,000 and $192,000 for the three months ended September 30, 2015 and 2014 , respectively, and $375,000 and $647,000 for the nine months ended September 30, 2015 and 2014 , respectively. TDRs: The Company takes a conservative approach with credit risk management and remains focused on community lending and reinvesting. The Company works closely with borrowers experiencing credit problems to assist in loan repayment or term modifications. TDR loans consist of loans where the Company, for economic or legal reasons related to the borrower’s financial difficulties, granted a concession to the borrower that it would not otherwise consider. TDRs, typically, involve term modifications or a reduction of either interest or principal. Once such an obligation has been restructured, it will remain a TDR until paid in full, or until the loan is again restructured at current market rates and no concessions are granted. The specific reserve allowance was determined by discounting the total expected future cash flows from the borrower at the original loan interest rate, or if the loan is currently collateral-dependent, using the NRV, which was obtained through independent appraisals and internal evaluations.

Regulatory Capital Requirements [Abstract]
Regulatory Capital Requirements under Banking Regulations [Text Block]	The Company and Bank are subject to various regulatory capital requirements administered by the FRB and the OCC. Failure to meet minimum capital requirements can result in mandatory and possible additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company’s consolidated financial statements. Effective January 1, 2015, the Company implemented the Basel III regulatory capital framework. These new rules and framework revised minimum capital requirements and adjusted prompt corrective action thresholds. The Company and Bank are required to maintain certain levels of capital based on risk-adjusted assets. These capital requirements represent quantitative measures of our assets, liabilities and certain off-balance sheet items as calculated under regulatory accounting practices. The Company and Bank's capital classification is also subject to qualitative judgments by our regulators about components, risk weightings and other factors. Under the Basel III regulatory capital framework, the quantitative measures established to ensure capital adequacy require us to maintain minimum amounts and ratios of total, Tier I capital, and common equity Tier I (as defined in the applicable regulations) to risk-weighted assets (as defined in the applicable regulations), and of Tier I capital to average assets, or leverage ratio (as defined in the applicable regulations). These guidelines apply to the Company on a consolidated basis. Under the current guidelines, banking organizations must have a minimum total risk-based capital ratio of 8.0% , a minimum Tier I risk-based capital ratio of 6.0% , a minimum common equity Tier I risk-based capital ratio of 4.5% , and a minimum leverage ratio of 4.0% . In addition to these requirements, banking organization must maintain a 2.5% capital conservation buffer consisting of common Tier I equity, subject to a transition schedule with a full phase-in by 2019. The Company and Bank's risk-based capital ratios exceeded regulatory guidelines at September 30, 2015 under the newly implemented Basel III regulatory capital framework. The Company and Bank's risk-based capital ratios under prior rules at December 31, 2014 also exceeded regulatory capital requirements under previous regulatory capital requirements in place. The following table presents the Company and Bank's regulatory capital ratios at the periods indicated: Current Regulatory Guidance Prior Regulatory Guidance September 30, Minimum Regulatory Capital Required Minimum Regulatory Provision To Be "Well Capitalized" Under Prompt Corrective Action Provisions December 31, Minimum Regulatory Capital Required Minimum Regulatory Provision To Be "Well Capitalized" Under Prompt Corrective Action Provisions Camden National Corporation: Total risk-based capital ratio 14.76 % 8.00 % N/A 15.16 % 8.00 % N/A Tier I risk-based capital ratio 13.67 % 6.00 % N/A 13.97 % 4.00 % N/A Common equity Tier I risk-based capital ratio (1) 11.44 % 4.50 % N/A N/A N/A N/A Tier I leverage capital ratio 9.41 % 4.00 % N/A 9.26 % 4.00 % N/A Camden National Bank: Total risk-based capital ratio 13.47 % 8.00 % 10.00 % 13.85 % 8.00 % 10.00 % Tier I risk-based capital ratio 12.37 % 6.00 % 8.00 % 12.65 % 4.00 % 6.00 % Common equity Tier I risk-based capital ratio (1) 12.37 % 4.50 % 6.50 % N/A N/A N/A Tier I leverage capital ratio 8.52 % 4.00 % 5.00 % 8.38 % 4.00 % 5.00 % (1) Common equity Tier I risk-based capital ratio was a new risk-based capital ratio implemented with Basel III on January 1, 2015. In addition, the OCC requires a minimum level of $2.5 million of Tier I capital to be maintained at Acadia Trust. As of September 30, 2015 and December 31, 2014, Acadia Trust met all of its capital requirements. Although the junior subordinated debentures are recorded as a liability on the Company's consolidated statements of condition, the Company is permitted, in accordance with regulatory guidelines, to include, subject to certain limits, the junior subordinated debentures in our calculation of risk-based capital. At September 30, 2015 and December 31, 2014, $43.0 million of the junior subordinated debentures were included in Tier I and total risk-based capital for the Company.

Banking and Thrift [Abstract]
REPURCHASE AGREEMENTS	NOTE 9 – REPURCHASE AGREEMENTS The Company can raise additional liquidity by entering into repurchase agreements at its discretion. In a security repurchase agreement transaction, the Company will generally sell a security, agreeing to repurchase either the same or substantially identical security on a specified later date, at a greater price than the original sales price. The difference between the sale price and purchase price is the cost of the proceeds, which is recorded as interest expense on the consolidated statement of income. The securities underlying the agreements are delivered to counterparties as security for the repurchase obligations. Since the securities are treated as collateral and the agreement does not qualify for a full transfer of effective control, the transactions does not meet the criteria to be classified as a sale, and is therefore considered a secured borrowing transaction for accounting purposes. Payments on such borrowings are interest only until the scheduled repurchase date. In a repurchase agreement the Company is subject to the risk that the purchaser may default at maturity and not return the securities underlying the agreements. In order to minimize this potential risk, the Company either deals with established firms when entering into these transactions or with customers whose agreements stipulate that the securities underlying the agreement are not delivered to the customer and instead are held in segregated safekeeping accounts by the Company's safekeeping agents. The table below sets forth information regarding the Company’s repurchase agreements accounted for as secured borrowings and types of collateral at the date indicated: September 30, 2015 Remaining Contractual Maturity of the Agreements Overnight and Continuous Up to 30 Days 30 - 90 Days Greater than 90 Days Total Customer Repurchase Agreements: Obligations of states and political subdivisions $ 372 $ — $ — $ — $ 372 Mortgage-backed securities issued or guaranteed by U.S. government-sponsored enterprises 102,016 — — — 102,016 Collateralized mortgage obligations issued or guaranteed by U.S. government-sponsored enterprises 71,415 — — — 71,415 Total Customer Repurchase Agreements 173,803 — — — 173,803 Wholesale Repurchase Agreements: Mortgage-backed securities issued or guaranteed by U.S. government-sponsored enterprises — — — 27,959 27,959 Collateralized mortgage obligations issued or guaranteed by U.S. government-sponsored enterprises — — — 2,104 2,104 Total Wholesale Repurchase Agreements — — — 30,063 30,063 Total Repurchase Agreements (1) $ 173,803 $ — $ — $ 30,063 $ 203,866 (1) Total repurchase agreements are presented within other borrowed funds on the consolidated statements of condition.

FAIR VALUE MEASUREMENT

FAIR VALUE MEASUREMENT	9 Months Ended

Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENT	FAIR VALUE MEASUREMENT AND DISCLOSURE Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value is best determined using quoted market prices. However, in many instances, quoted market prices are not available. In such instances, fair values are determined using various valuation techniques. Various assumptions and observable inputs must be relied upon in applying these techniques. GAAP establishes a fair value hierarchy for valuation inputs that gives the highest priority to quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. GAAP permits an entity to choose to measure eligible financial instruments and other items at fair value. The Company has elected the fair value option for its loans held for sale. Electing the fair value option for loans held for sale enables the Company’s financial position to more clearly align with the economic value of the actively traded asset. The fair value hierarchy for valuation of an asset or liability is as follows: Level 1: Valuation is based upon unadjusted quoted prices in active markets for identical assets and liabilities that the entity has the ability to access as of the measurement date. Level 2: Valuation is determined from quoted prices for similar assets or liabilities in active markets, from quoted prices for identical or similar instruments in markets that are not active or by model-based techniques in which all significant inputs are observable in the market. Level 3: Valuation is derived from model-based and other techniques in which at least one significant input is unobservable and which may be based on the Company’s own estimates about the assumptions that market participants would use to value the asset or liability. In general, fair value is based upon quoted market prices, where available. If such quoted market prices are not available, fair value is based upon model-based techniques incorporating various assumptions including interest rates, prepayment speeds and credit losses. Assets and liabilities valued using model-based techniques are classified as either Level 2 or Level 3, depending on the lowest level classification of an input that is considered significant to the overall valuation. 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. Financial Instruments Recorded at Fair Value on a Recurring Basis Loans Held For Sale: The fair value of loans held for sale is determined using quoted secondary market prices or executed sales agreements and is classified as Level 2. AFS Securities : The fair value of debt AFS securities is reported utilizing prices provided by an independent pricing service based on recent trading activity and other observable information including, but not limited to, dealer quotes, market spreads, cash flows, market interest rate curves, market consensus prepayment speeds, credit information, and the bond’s terms and conditions. The fair value of debt securities are classified as Level 2. Derivatives : The fair value of interest rate swaps is determined using inputs that are observable in the market place obtained from third parties including yield curves, publicly available volatilities, and floating indexes and, accordingly, are classified as Level 2 inputs. The credit value adjustments associated with derivatives utilize Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default by the Company and its counterparties. As of September 30, 2015 and December 31, 2014 , 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 due to collateral postings. The following table summarizes financial assets and financial liabilities measured at fair value on a recurring basis as of September 30, 2015 and December 31, 2014 , segregated by the level of the valuation inputs within the fair value hierarchy utilized to measure fair value: Fair Value Readily Available Market Prices (Level 1) Observable Market Data (Level 2) Company Determined Fair Value (Level 3) September 30, 2015 Financial assets: Loans held for sale $ 890 $ — $ 890 $ — AFS securities: Obligations of U.S. government-sponsored enterprises 5,094 — 5,094 — Obligations of states and political subdivisions 19,872 — 19,872 — Mortgage-backed securities issued or guaranteed by U.S. government-sponsored enterprises 381,049 — 381,049 — Collateralized mortgage obligations issued or guaranteed by U.S. government-sponsored enterprises 318,222 — 318,222 — Customer interest rate swap agreements 3,188 — 3,188 — Financial liabilities: Interest rate swap agreements 10,165 — 10,165 — Forward-starting interest rate swap agreements 887 — 887 — Customer interest rate swap agreements 3,188 — 3,188 — December 31, 2014 Financial assets: AFS securities: Obligations of U.S. government-sponsored enterprises $ 5,027 $ — $ 5,027 $ — Obligations of states and political subdivisions 26,777 — 26,777 — Mortgage-backed securities issued or guaranteed by U.S. government-sponsored enterprises 381,308 — 381,308 — Collateralized mortgage obligations issued or guaranteed by U.S. government-sponsored enterprises 343,897 — 343,897 — Private issue collateralized mortgage obligations 6,054 — 6,054 — Customer interest rate swap agreements 1,140 — 1,140 — Financial liabilities: Interest rate swap agreements 9,143 — 9,143 — Customer interest rate swap agreements 1,140 — 1,140 — The Company did not have any transfers between Level 1 and Level 2 of the fair value hierarchy during the nine months ended September 30, 2015 . The Company’s policy for determining transfers between levels occurs at the end of the reporting period when circumstances in the underlying valuation criteria change and result in transfer between levels. Financial Instruments Recorded at Fair Value on a Nonrecurring Basis The Company may be required, from time to time, to measure certain financial assets and financial liabilities at fair value on a nonrecurring basis in accordance with GAAP. These include assets that are measured at the lower of cost or market value that were recognized at fair value below cost at the end of the period. Collateral-Dependent Impaired Loans : Loans for which it is probable that payment of interest and principal will not be made in accordance with the contractual terms of the loan agreement are considered impaired. The Company's policy is to individually evaluate for impairment loans with a principal balance greater than $250,000 or more and are classified as substandard or doubtful and are on non-accrual status. Once the population of loans is identified for individual impairment assessment, the Company measures these loans for impairment by comparing NRV, which is the fair value of the collateral, less estimated costs to sell, to the carrying value of the loan. If the NRV of the loan is less than the carrying value of the loan, then a loss is recognized as part of the ALL to adjust the loan's carrying value to NRV. Accordingly, certain collateral-dependent impaired loans are subject to measurement at fair value on a non-recurring basis. Management has estimated the fair values of these assets using Level 2 inputs, such as the fair value of collateral based on independent third-party market approach appraisals for collateral-dependent loans, and Level 3 inputs where circumstances warrant an adjustment to the appraised value based on the age of the appraisal and/or comparable sales, condition of the collateral, and market conditions. MSRs : The Company accounts for mortgage servicing assets at cost, subject to impairment testing. When the carrying value of a tranche exceeds fair value, a valuation allowance is established to reduce the carrying cost to fair value. Fair value is based on a valuation model that calculates the present value of estimated net servicing income. The Company obtains a third-party valuation based upon loan level data including note rate, type and term of the underlying loans. The model utilizes a variety of observable inputs for its assumptions, the most significant of which are loan prepayment assumptions and the discount rate used to discount future cash flows. Other assumptions include delinquency rates, servicing cost inflation and annual unit loan cost. MSRs are classified within Level 2 of the fair value hierarchy. Non-Financial Assets and Non-Financial Liabilities Recorded at Fair Value on a Non-Recurring Basis The Company has no non-financial assets or non-financial liabilities measured at fair value on a recurring basis. Non-financial assets measured at fair value on a non-recurring basis consist of OREO and goodwill and other intangible assets. OREO : OREO properties acquired through foreclosure or deed in lieu of foreclosure are recorded at NRV, which is the fair value of the real estate, less estimated costs to sell. Any write-down of the recorded investment in the related loan is charged to the ALL upon transfer to OREO. Upon acquisition of a property, a current appraisal is used or an internal valuation is prepared to substantiate fair value of the property. After foreclosure, management periodically, but at least annually, obtains updated valuations of the OREO properties and, if additional impairments are deemed necessary, the subsequent write-downs for declines in value are recorded through a valuation allowance and a provision for losses charged to other non-interest expense within the consolidated statements of income. As management considers appropriate, adjustments are made to the appraisal obtained for the OREO property to account for recent sales activity of comparable properties, changes in the condition of the property, and changes in market conditions. These adjustments are not observable in an active market and are classified as Level 3. Goodwill and Other Intangible Assets : Goodwill represents the excess cost of an acquisition over the fair value of the net assets acquired. The fair value of goodwill is estimated by utilizing several standard valuation techniques, including discounted cash flow analyses, bank merger multiples, and/or an estimation of the impact of business conditions and investor activities on the long-term value of the goodwill. Should an impairment of either reporting unit's goodwill occur, the associated goodwill is written-down to fair value and the impairment charge is recorded within non-interest expense in the consolidated statements of income. The Company conducts an annual impairment test of goodwill in the fourth quarter each year, or more frequently as necessary. There have been no indications or triggering events during the first nine months of 2015 for which management believes that it is more likely than not that goodwill is impaired. The Company's core deposit intangible assets represent the estimated value of acquired customer relationships and are amortized on a straight-line basis over the estimated life of those relationships. Core deposit intangibles are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. If necessary, management will test the core deposit intangibles for impairment by comparing its carrying value to the expected undiscounted cash flows of the assets. If the undiscounted cash flows of the intangible assets exceed its carrying value then the intangible assets are deemed to be fully recoverable and not impaired. However, if the undiscounted cash flows of the intangible assets are less than its carrying value than an impairment charge is recorded to mark the carrying value of the intangible assets to fair value. There were no events or changes in circumstances during the first nine months of 2015 that indicated the carrying amount may not be recoverable. The table below highlights financial and non-financial assets measured and recorded at fair value on a non-recurring basis as of September 30, 2015 and December 31, 2014 . Not included in the table below because they were not recorded at fair value at September 30, 2015 and December 31, 2014 are: (i) impaired loans of $13.2 million and $17.6 million, respectively; (ii) MSRs reported of $165,000 and $319,000 , respectively; and (iii) OREO properties of $0 and $305,000 , respectively.

The methodologies for estimating the fair value of financial assets and financial liabilities that are measured at fair value on a recurring or non-recurring basis are discussed above. The following methods and assumptions were used by the Company in estimating the fair values of its other financial instruments. Cash and Due from Banks : The carrying amounts reported in the consolidated statements of condition approximate fair value. HTM securities : The fair value is estimated utilizing prices provided by an independent pricing service based on recent trading activity and other observable information including, but not limited to, dealer quotes, market spreads, cash flows, market interest rate curves, market consensus prepayment speeds, credit information, and the bond’s terms and conditions. The fair value is classified as Level 2. Loans : For variable rate loans that reprice frequently and have no significant change in credit risk, fair values are based on carrying values. The fair value of other loans is estimated by discounting the future cash flows using the current rates at which similar loans would be made to borrowers with similar credit ratings and for the same remaining maturities. Interest Receivable and Payable : The carrying amounts reported in the consolidated statements of condition approximate fair value. Deposits : The fair value of deposits with no stated maturity is equal to the carrying amount. The fair value of certificates of deposit is estimated using a discounted cash flow calculation that applies interest rates and remaining maturities for currently offered certificates of deposit. Borrowings : The carrying amounts of short-term borrowings from the FHLB, securities sold under repurchase agreements, notes payable and other short-term borrowings approximate fair value. The fair values of long-term borrowings and commercial repurchase agreements are based on the discounted cash flows using current rates for advances of similar remaining maturities. Junior Subordinated Debentures : The carrying amounts reported in the consolidated statements of condition approximate fair value.

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES Legal Contingencies In the normal course of business, the Company and its subsidiaries are subject to pending and threatened legal actions. Although the Company is not able to predict the outcome of such actions, after reviewing pending and threatened actions with counsel, management believes that based on the information currently available the outcome of such actions, individually or in the aggregate, will not have a material adverse effect on the Company’s consolidated financial position as a whole. Reserves are established for legal claims only when losses associated with the claims are judged to be probable and the loss can be reasonably estimated. In many lawsuits and arbitrations, it is not possible to determine whether a liability has been incurred or to estimate the ultimate or minimum amount of that liability until the case is close to resolution, in which case a reserve will not be recognized until that time. As of September 30, 2015 , the Company did no t have any material loss contingencies for which accruals were provided for and/or disclosure was deemed necessary. Financial Instruments In the normal course of business, the Company is a party to both on and off-balance sheet financial instruments involving, to varying degrees, elements of credit risk and interest rate risk in addition to the amounts recognized in the consolidated statements of condition. The following is a summary of the contractual and notional amounts of the Company’s financial instruments: September 30, December 31, Lending-Related Instruments: Loan origination commitments and unadvanced lines of credit: Home equity $ 336,459 $ 303,815 Commercial and commercial real estate 45,729 47,066 Residential 17,608 10,975 Letters of credit 2,436 3,103 Other commitments 651 1,305 Derivative Financial Instruments: Interest rate swaps 43,000 43,000 Forward-starting interest rate swaps 50,000 — Customer loan swaps 171,302 58,234 Lending-Related Instruments The contractual amounts of the Company’s lending-related financial instruments do not necessarily represent future cash requirements since certain of these instruments may expire without being funded and others may not be fully drawn upon. These instruments are subject to the Company’s credit approval process, including an evaluation of the customer’s creditworthiness and related collateral requirements. Commitments generally have fixed expiration dates or other termination clauses. Derivative Financial Instruments The Company uses derivative financial instruments for risk management purposes (primarily interest rate risk) and not for trading or speculative purposes. The Company controls the credit risk of these instruments through collateral, credit approvals and monitoring procedures. Interest Rate Swaps: The Company’s interest rate swap arrangements contain provisions that require the Company to post cash collateral with the counterparty for contracts that are in a net liability position based on their fair values and the Company’s credit rating. The Company had a notional amount of $43.0 million in variable-for-fixed interest rate swap agreements on its junior subordinated debentures and $10.3 million in cash held as collateral. The terms of the interest rate swap agreements are as follows: September 30, 2015 December 31, 2014 Notional Trade Maturity Date Variable Index Fixed Rate Fair Value (1) Fair Value (1) $ 10,000 3/18/2009 6/30/2021 3-Month USD LIBOR 5.09% $ (1,240 ) $ (1,092 ) 10,000 7/8/2009 6/30/2029 3-Month USD LIBOR 5.84% (2,763 ) (2,511 ) 10,000 5/6/2010 6/30/2030 3-Month USD LIBOR 5.71% (2,697 ) (2,434 ) 5,000 3/14/2011 3/30/2031 3-Month USD LIBOR 4.35% (1,414 ) (1,279 ) 8,000 5/4/2011 7/7/2031 3-Month USD LIBOR 4.14% (2,051 ) (1,827 ) $ 43,000 $ (10,165 ) $ (9,143 ) (1) Presented within accrued interest and other liabilities on the consolidated statements of condition. As each derivative instrument qualifies as a highly effective cash flow hedge, the decrease in the fair value of the interest rate swaps for the nine months ended September 30, 2015 of $665,000 , net of tax, was recorded in OCI. Net payments have been classified as cash flows from operating activities in the consolidated statements of cash flows. The Company would reclassify unrealized gains or losses accounted for within AOCI into earnings if the interest rate swaps were to become ineffective or the arrangements were to terminate. In the next 12 months, the Company does not believe it will reclassify any related unrealized gains or losses accounted for within AOCI into earnings. Forward-Starting Interest Rate Swaps: In the first quarter of 2015, the Bank entered into two interest rate swap arrangements with a counterparty for a total notional amount of $50.0 million . Each derivative arrangement will commence on February 25, 2016, with one contract set to expire on February 25, 2018 and the other on February 25, 2019. The Bank entered into these forward-starting interest rate swaps to mitigate its cost of borrowings exposure in a rising interest rate environment. The Bank has designated each arrangement as a hedge in accordance with GAAP, and, therefore, the change in unrealized gains or losses on the derivative instruments is recorded within AOCI, net of tax. Also, quarterly, in conjunction with financial reporting, the Company assesses each derivative instrument for ineffectiveness. To the extent any significant ineffectiveness is identified this amount would be recorded within the consolidated statements of income. For the three and nine months ended September 30, 2015 the Company did no t record any ineffectiveness within the consolidated statements of income. The Bank's arrangement with the counterparty requires it to post cash collateral for contracts in a net liability position based on their fair values and the Bank's credit rating. At September 30, 2015 , the Bank posted cash collateral with the counterparty of $824,000 . The terms of the interest rate swap agreements are as follows: September 30, 2015 Notional Trade Maturity Date Variable Index Fixed Rate Fair Value (1) $ 25,000 2/25/2015 2/25/2018 30-Day FHLBB 1.54% $ (356 ) 25,000 2/25/2015 2/25/2019 30-Day FHLBB 1.74% (531 ) $ 50,000 $ (887 ) (1) Presented within accrued interest and other liabilities on the consolidated statements of condition. As each derivative instrument qualifies as a highly effective cash flow hedge, the decrease in the fair value of the interest rate swaps for the nine months ended September 30, 2015 of $576,000 , net of tax, was recorded in OCI. Net payments have been classified as cash flows from operating activities in the consolidated statements of cash flows. In the next 12 months, the Company does not believe it will reclassify any related unrealized gains or losses accounted for within AOCI into earnings. Customer Loan Swaps: The Company will enter into interest rate swaps with its commercial customers, from time to time, to provide them with a means to lock into a long-term fixed rate, while simultaneously the Company enters into an arrangement with a counterparty to swap the fixed rate to a variable rate to allow it to effectively manage its interest rate exposure. At September 30, 2015 and December 31, 2014, the Company had interest rate swap agreements with a total notional amount of $85.7 million and $29.1 million , respectively, with its commercial customers, and interest rate swap agreements of equal notional amounts with a dealer bank. The Company's customer loan level derivative program is not designated as a hedge for accounting purposes. As the interest rate swap agreements have substantially equivalent and offsetting terms, they do not materially change the Company’s interest rate risk or present any material exposure to the Company's consolidated statements of income. The Company records its customer loan swaps at fair value and presents such on a gross basis within other assets and accrued interest and other liabilities on the consolidated statements of condition. The fair value of customer loan swaps at September 30, 2015 and December 31, 2014 were $3.2 million and $1.1 million , respectively. The Company seeks to mitigate its customer counterparty credit risk exposure through its loan policy and underwriting process, which includes credit approval limits, monitoring procedures, and obtaining collateral, where appropriate. The Company seeks to mitigate its institutional counterparty credit risk exposure by limiting the institutions for which it will enter into interest swap arrangements through an approved listing by the Company's board of directors. The Company's arrangement with an institutional counterparty requires it to post cash collateral for contracts in a net liability position based on their fair values and the Bank's credit rating or receive cash collateral for contracts in a net asset position. At September 30, 2015 , the Company posted cash collateral with the counterparty of $3.0 million . Interest Rate Locks: As part of originating residential mortgages, the Company may enter into rate lock agreements with customers, which are considered interest rate lock commitments. At September 30, 2015 and December 31, 2014 , based upon the pipeline of mortgage loans with rate lock commitments, the fair value of these commitments was immaterial to the Company's consolidated financial statements.

MERGER AND ACQUISITION COSTS	MERGER AND ACQUISITION ACTIVITY On October 16, 2015, the Company completed its previously announced acquisition of SBM pursuant to the terms and conditions of the Merger Agreement. Additionally, The Bank of Maine, a wholly owned subsidiary of SBM, merged with and into Camden National Bank, with Camden National Bank continuing as the surviving bank. Pursuant to the Merger Agreement, each share of SBM common stock outstanding at the effective time of the Merger was converted into the right to receive, at the election of the stockholder and subject to the allocation and proration procedures described in the Merger Agreement, either: (1) $206.00 in cash, without interest or (2) 5.421 shares of common stock of the Company; provided that 80% of the SBM shares outstanding immediately prior to the effective time of the Merger were converted into the right to receive common stock of the Company and the remaining SBM shares were converted into the right to receive cash. The total consideration paid by the Company was approximately $136.7 million , consisting of (i) approximately $26.1 million in cash; (ii) 2,749,762 shares of Camden common stock valued at approximately $108.6 million based on the October 16, 2015 closing price of $39.48 per share; and (iii) the fair value of 92,688 non-qualified stock options issued under the 2012 Plan of $2.0 million . As of October 16, 2015, SBM's total assets were approximately $815.0 million , total net loans were approximately $640.0 million , and total deposits and borrowings were approximately $710.0 million . These balances are unaudited and do not include any adjustments for purchase accounting. As a result of the proximity of the closing of the merger to the date these consolidated financial statements were available to be issued, the Company continues to evaluate the estimated fair values of the assets acquired and the liabilities assumed. Accordingly, the amount of any goodwill and other intangible assets to be recognized in connection with this transaction is also yet to be determined. Upon completion of the Merger on October 16, 2015, the Company had 10,203,807 shares of common stock outstanding. In conjunction with the Merger, the Company incurred certain non-recurring costs, including legal fees, investment banking fees, and other integration-related costs for the three and nine months ended September 30, 2015 of $766,000 and $1.6 million, respectively. These non-recurring costs are presented on the consolidated statements of income within non-interest expense as merger and acquisition costs. In addition, the Company incurred certain equity issuance costs totaling $537,000 related to the registration of additional shares of the Company's common stock. These costs have been accounted for as a reduction to shareholders' equity. In accordance with the Internal Revenue Code, certain non-recurring costs are not deductible for income tax purposes. The impact to the Company's effective tax rate for the nine months ended September 30, 2015 was an increase of 2.1% . Non-recurring costs incurred for the three months ended September 30, 2015 had no impact on the Company's three months ended effective tax rate.

New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
RECENT ACCOUNTING PRONOUNCEMENTS	RECENT ACCOUNTING PRONOUNCEMENTS In January 2015, the FASB issued ASU No. 2015-01, Income Statement - Extraordinary and Unusual Items (Subtopic 225-30): Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary Items . The ASU was issued as part of the FASB's simplification initiative to reduce complexity in accounting standards by eliminating the concept of extraordinary items. The ASU is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2015. The ASU does not have a material effect on the Company's consolidated financial statements. In April 2015, the FASB issued ASU No. 2015-03, Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs. The ASU was issued to simplify the presentation of debt issuance costs as part of the FASB's simplification initiative. The ASU requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct reduction of the carrying amount of that debt liability, consistent with debt discounts. The ASU is effective for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. The new guidance will be applied on a retrospective basis, which will require disclosure of this as a change in accounting principle. The Company does not expect the ASU to have a material effect on its consolidated financial statements. In April 2015, the FASB issued ASU No. 2015-05, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customer's Accounting for Fees Paid in a Cloud Computing Arrangement. The ASU was issued because existing GAAP did not include explicit guidance for accounting for fees paid in a cloud computing arrangement. The ASU is effective for annual periods, including interim periods within those annual periods, beginning after December 15, 2015. The Company does not expect the ASU to have a material effect on its consolidated financial statements. In August 2015, the FASB issued ASU No. 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date. The ASU was issued to defer the effective date of Update 2014-09, Revenue from Contracts with Customers (Topic 606), for all entities by one year. ASU 2014-09 was issued to clarify the principles for recognizing revenue and to develop a common revenue standard. ASU 2014-09 is now effective for annual reporting periods beginning after December 15, 2017, including interim reporting periods within that reporting period. The Company continues to evaluate the potential impact of ASU 2014-09, as updated by ASU 2015-14, but currently does not expect the ASU to have a material effect on its consolidated financial statements. In September 2015, the FASB issued ASU No. 2015-16, Business Combinations (Topic 805) : Simplifying the Accounting for Measurement-Period Adjustments. The ASU was issued to simplify measurement period accounting, by requiring recognition of measurement period adjustments identified in the reporting period in which they are determined instead of applying them retrospectively. The ASU is effective for fiscal years beginning after December 15, 2015, including interim periods within those fiscal years and early application is permitted. The Company is evaluating the potential impact of the ASU on its consolidated financial statements.
