Accounting Policies [Abstract]
Basis of Presentation	Note 1 – Basis of Presentation General In the opinion of management, the accompanying unaudited consolidated financial statements contain all adjustments necessary to present fairly Nicolet Bankshares, Inc. (the “Company”) and its subsidiaries, consolidated balance sheets, statements of income, comprehensive income, changes in stockholders’ equity and cash flows for the periods presented, and all such adjustments are of a normal recurring nature. All material intercompany transactions and balances are eliminated. The results of operations for the interim periods are not necessarily indicative of the results to be expected for the entire year. These interim consolidated financial statements have been prepared according to the rules and regulations of the Securities and Exchange Commission and, therefore, certain information and footnote disclosures normally presented in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) have been omitted or abbreviated. These consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and footnotes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2015. Critical Accounting Policies and Estimates Preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying disclosures. These estimates are based on management’s best knowledge of current events and actions the Company may undertake in the future. Estimates are used in accounting for, among other items, the allowance for loan losses, useful lives for depreciation and amortization, fair value of financial instruments, deferred tax assets, uncertain income tax positions and contingencies. Estimates that are particularly susceptible to significant change for the Company include the determination of the allowance for loan losses, the assessment of deferred tax assets and liabilities, and the valuation of loans acquired in acquisitions; therefore, these are critical accounting policies. Factors that may cause sensitivity to the aforementioned estimates include but are not limited to: external market factors such as market interest rates and employment rates, changes to operating policies and procedures, changes in applicable banking regulations, and changes to deferred tax estimates. Actual results may ultimately differ from estimates, although management does not generally believe such differences would materially affect the consolidated financial statements in any individual reporting period presented. There have been no material changes or developments with respect to the assumptions or methodologies that the Company uses when applying what management believes are critical accounting policies and developing critical accounting estimates as disclosed in the Company’s Annual Report on Form 10-K for the year ended December 31, 2015. Recent Accounting Developments Adopted The Company has implemented all new accounting pronouncements that are in effect and that may impact its consolidated financial statements or results of operations. Operating Segment While the chief decision makers monitor the revenue streams of the various products and services, and evaluate costs, balance sheet positions and quality, all such products, services and activities are directly or indirectly related to the business of community banking, with no regular, formal or material segment delineations. Operations are managed and financial performance is evaluated on a company-wide basis, and accordingly, all the financial service operations are considered by management to be aggregated in one reportable operating segment. Reclassifications Certain amounts in the 2015 consolidated financial statements have been reclassified to conform to the 2016 presentation.

Acquisitions

Business Combinations [Abstract]
Acquisitions	Note 2 – Acquisitions On April 29, 2016, the Company consummated its merger with Baylake Corp. (“Baylake”), pursuant to the Agreement and Plan of Merger by and between the Company and Baylake dated September 8, 2015, (the “Merger Agreement”), whereby Baylake was merged with and into the Company, and Baylake Bank, Baylake’s wholly owned commercial bank subsidiary serving northeastern Wisconsin, was merged with and into Nicolet National Bank. The system integration was completed, and 21 branches of Baylake opened, on May 2, 2016, as Nicolet National Bank branches, expanding its presence into Door, Kewaunee, and Manitowoc Counties, Wisconsin. Concurrently, Nicolet closed one of its Brown County locations, bringing the Bank’s footprint to 42 branches as of September 30, 2016. The purpose of the merger was for strategic reasons beneficial to the Company. The acquisition is consistent with its plan to drive growth and efficiency through increased scale, leverage the strengths of each bank across the combined customer base, enhance profitability, and add liquidity and shareholder value. Pursuant to the terms of the Merger Agreement, Baylake shareholders received 0.4517 shares of the Company’s common stock for each outstanding share of Baylake common stock (except for Baylake shares pre-owned by the Company at the time of the merger), and cash in lieu of any fractional share. Pre-existing Baylake equity awards (restricted stock units and stock options) immediately vested upon consummation of the merger. The Company issued 0.4517 shares of its common stock for each vesting Baylake restricted stock unit, and Nicolet assumed, after appropriate adjustment by the 0.4517 exchange ratio, all pre-existing Baylake stock options. As a result, the Company issued 4,344,243 shares of the Company’s common stock, for common stock consideration of $163.3 million (based on $37.58 per share, the volume weighted average closing price of the Company’s common stock over the preceding 20 trading day period, and recorded an additional $1.2 million consideration for the assumed stock options. Approximately $0.3 million in direct stock issuance costs for the merger were incurred and charged against additional paid in capital, bringing the total purchase price to $164.2 million. The Company accounted for the transaction under the acquisition method of accounting, and thus, the financial position and results of operations of Baylake prior to the consummation date were not included in the accompanying consolidated financial statements. The accounting required assets purchased and liabilities assumed to be recorded at their respective fair values at the date of acquisition. The Company determined the fair value of core deposit intangibles, securities, premises and equipment, loans, OREO, BOLI and other assets, deposits, debt and deferred taxes with the assistance of third party valuations, appraisals, and third party advisors. The estimated fair values will be subject to refinement as additional information relative to the closing date fair values becomes available through the measurement period of approximately one year from consummation. The fair value of the assets acquired and liabilities assumed on April 29, 2016 was as follows: (in millions) As recorded by Fair Value As Recorded Cash, cash equivalents and securities available for sale $ 262 $ 1 $ 263 Loans 710 (19 ) 691 Other real estate owned 3 (2 ) 1 Core deposit intangible 1 16 17 Fixed assets and other assets 71 (8 ) 63 Total assets acquired $ 1,047 $ (12 ) $ 1,035 Deposits $ 822 $ - $ 822 Junior subordinated debentures, borrowings and other liabilities 116 (1 ) 115 Total liabilities acquired $ 938 $ (1 ) $ 937 Excess of assets acquired over liabilities acquired $ 109 $ (11 ) $ 98 Less: purchase price 164 Goodwill $ 66 The following unaudited pro forma information presents the results of operations for three months and nine months ended September 30, 2016 and 2015, as if the acquisition had occurred January 1 of each period. The Company expects to achieve further operating cost savings and other business synergies as a result of the acquisition which are not reflected in the pro forma amounts. These unaudited pro forma results are presented for illustrative purposes and are not intended to represent or be indicative of the actual results of operations of the combined company that would have been achieved had the acquisition occurred at the beginning of each period presented, nor are they intended to represent or be indicative of future results of operations.

The transaction was effected in phases and completed April 1, 2016. The Company paid $4.9 million total initial consideration, including $0.8 million cash, $2.6 million of Nicolet common stock, and recorded a $1.5 million earn-out liability payable to one principal in the future (which may require adjustment based on change in initial business purchased over a period, but not contingent upon the principal’s employment). The Company initially recorded $0.4 million of goodwill, $0.2 million of fixed assets, and $4.3 million of customer relationship intangibles (a portion amortizing straight-line over 10 years and a portion over 15 years). The transaction will impact the income statement primarily within brokerage income, personnel expense, and intangibles amortization.

Earnings Per Share [Abstract]
Earnings per Common Share	Note 3 – Earnings per Common Share Basic earnings per common share are calculated by dividing net income available to common shareholders by the weighted average number of common shares outstanding during the period. Diluted earnings per share is calculated by dividing net income available to common shareholders by the weighted average number of shares adjusted for the dilutive effect of common stock awards (outstanding stock options and unvested restricted stock), if any. Presented below are the calculations for basic and diluted earnings per common share. Three Months Ended Nine Months Ended 2016 2015 2016 2015 (In thousands except per share data) Net income, net of noncontrolling interest $ 6,464 $ 2,594 $ 12,375 $ 8,609 Less: preferred stock dividends 247 60 633 182 Net income available to common shareholders $ 6,217 $ 2,534 $ 11,742 $ 8,427 Weighted average common shares outstanding 8,608 3,961 6,689 4,000 Effect of dilutive stock instruments 362 437 335 358 Diluted weighted average common shares outstanding 8,970 4,398 7,024 4,358 Basic earnings per common share* $ 0.72 $ 0.64 $ 1.76 $ 2.11 Diluted earnings per common share* $ 0.69 $ 0.58 $ 1.67 $ 1.93 *Cumulative quarterly per share performance may not equal annual per share totals due to the effects of the amount and timing of capital increases. When computing earnings per share for an interim period, the denominator is based on the weighted-average shares outstanding during the interim period, and not on an annualized weighted-average basis. Accordingly, the sum of the quarters' earnings per share data will not necessarily equal the year to date earnings per share data. No shares were outstanding at September 30, 2016 which were excluded from the calculation of diluted earnings per common share as anti-dilutive. Options to purchase approximately 0.2 million shares were outstanding at September 30, 2015, but were excluded from the calculation of diluted earnings per common share as the effect would have been anti-dilutive.

Stock-based Compensation	Note 4 – Stock-based Compensation A Black-Scholes model is utilized to estimate the fair value of stock options and the market price of the Company’s stock at the date of grant is used to estimate the value of restricted stock awards. The weighted average assumptions used in the model for valuing option grants were as follows: Nine months ended Year ended Dividend yield 0 % 0 % Expected volatility 25 % 25 % Risk-free interest rate 1.52 % 1.68 % Expected average life 7 years 7 years Weighted average per share fair value of options $ 11.04 $ 8.11 Activity in the Company’s Stock Incentive Plans is summarized in the following tables: Stock Options Weighted- Option Shares Weighted- Exercisable Balance – December 31, 2014 967,859 $ 19.30 630,121 Granted $ 8.11 162,000 26.66 Exercise of stock options* (381,505 ) 18.00 Forfeited (2,350 ) 19.61 Balance – December 31, 2015 746,004 21.56 325,979 Granted $ 11.04 170,500 36.86 Options assumed in acquisition 91,701 21.03 Exercise of stock options* (72,783 ) 20.90 Forfeited (1,456 ) 21.71 Balance – September 30, 2016 933,966 $ 24.35 407,779 *The terms of the stock option agreements permit having a number of shares of stock withheld, the fair market value of which as of the date of exercise is sufficient to satisfy the exercise price and/or tax withholding requirements. Options outstanding at September 30, 2016 are exercisable at option prices ranging from $9.19 to $38.10.

As of September 30, 2016, the Company does not consider securities with unrealized losses to be other-than-temporarily impaired as the unrealized losses in each category have occurred as a result of changes in interest rates, market spreads and market conditions subsequent to purchase. The Company has the ability and intent to hold its securities to maturity. There were no other-than-temporary impairments charged to earnings during the nine-month periods ending September 30, 2016 or September 30, 2015. The amortized cost and fair values of securities available for sale at September 30, 2016 by contractual maturity are shown below. Expected maturities may differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties. Fair values of securities are estimated based on financial models or prices paid for the same or similar securities. It is possible interest rates could change considerably, resulting in a material change in estimated fair value .

Although the Company has a diversified loan portfolio, the credit risk in the loan portfolio is largely influenced by general economic conditions and trends of the counties and markets in which the debtors operate, and the resulting impact on the operations of borrowers or on the value of underlying collateral, if any. The allowance for loan and lease losses (“ALLL”) represents management’s estimate of probable and inherent credit losses in the Company’s loan portfolio at the balance sheet date. In general, estimating the amount of the ALLL is a function of a number of factors, including but not limited to changes in the loan portfolio, net charge-offs, trends in past due and impaired loans, and the level of potential problem loans, all of which may be susceptible to significant change. To the extent actual outcomes differ from management estimates, additional provisions for loan losses could be required that could adversely affect our earnings or financial position in future periods. Allocations to the ALLL may be made for specific loans but the entire ALLL is available for any loan that, in management’s judgment, should be charged-off or for which an actual loss is realized. The allocation methodology used by the Company includes specific allocations for impaired loans evaluated individually for impairment based on collateral values and for the remaining loan portfolio collectively evaluated for impairment primarily based on historical loss rates and other qualitative factors. Loan charge-offs and recoveries are based on actual amounts charged-off or recovered by loan category. Management allocates the ALLL by pools of risk within each loan portfolio.

Some credits in these rating categories may require a need for monitoring but elements of concern are not severe enough to warrant an elevated rating. 5 Watch: Credits with this rating are adequately secured and performing but are being monitored due to the presence of various short-term weaknesses which may include unexpected, short-term adverse financial performance, managerial problems, potential impact of a decline in the entire industry or local economy and delinquency issues. Loans to individuals or loans supported by guarantors with marginal net worth or collateral may be included in this rating category. 6 Special Mention: Credits with this rating have potential weaknesses that, without the Company’s attention and correction may result in deterioration of repayment prospects. These assets are considered Criticized Assets. Potential weaknesses may include adverse financial trends for the borrower or industry, repeated lack of compliance with Company requests, increasing debt to net worth, serious management conditions and decreasing cash flow. 7 Substandard: Assets with this rating are characterized by the distinct possibility the Company will sustain some loss if deficiencies are not corrected. All foreclosures, liquidations, and non-accrual loans are considered to be categorized in this rating, regardless of collateral sufficiency. 8 Doubtful: Assets with this rating exhibit all the weaknesses as one rated Substandard with the added characteristic that such weaknesses make collection or liquidation in full highly questionable. 9 Loss: Assets in this category are considered uncollectible. Pursuing any recovery or salvage value is impractical but does not preclude partial recovery in the future.

For determining the adequacy of the ALLL, management defines impaired loans as nonaccrual credit relationships over $250,000, plus additional loans with impairment risk characteristics. At the time an individual loan goes into nonaccrual status, however, management evaluates the loan for impairment and possible charge-off regardless of loan size. In determining the appropriateness of the ALLL, management includes allocations for specifically identified impaired loans and loss factor allocations for all remaining loans, with a component primarily based on historical loss rates and another component primarily based on other qualitative factors. Impaired loans are individually assessed and are measured based on the present value of expected future cash flows discounted at the loan’s effective interest rate or, as a practical expedient, at the loan’s observable market price or the fair value of the collateral if the loan is collateral dependent. Loans that are determined not to be impaired are collectively evaluated for impairment, stratified by type and allocated loss ranges based on the Company’s actual historical loss ratios for each strata, and adjustments are also provided for certain current environmental and qualitative factors. An internal loan review function rates loans using a grading system based on nine different categories. Loans with grades of seven or higher (“classified loans”) represent loans with a greater risk of loss and may be assigned allocations for loss based on specific review of the weaknesses observed in the individual credits if classified as impaired. Classified loans are constantly monitored by the loan review function to ensure early identification of any deterioration. The following tables present impaired loans as of September 30, 2016 and December 31, 2015. As a further breakdown, impaired loans are also summarized by originated and acquired for the periods presented. In April 2016, the Baylake merger added purchased credit impaired loans at a fair value of $20.8 million, net of an initial $12.9 million non-accretable mark. Including these credit impaired loans acquired in the Baylake merger, total purchased credit impaired loans acquired in aggregate were initially recorded at a fair value of $37.5 million on their respective acquisition dates, net of an initial $25.1 million non-accretable mark and a zero accretable mark. At September 30, 2016, $20.0 million of the $37.5 million remain in impaired loans and $0.3 million of acquired loans have subsequently become impaired, bringing acquired impaired loans to $20.3 million.

There were no loans classified as troubled debt restructurings during the previous twelve months that subsequently defaulted as of September 30, 2016. Loans which were considered troubled debt restructurings by Baylake prior to the acquisition are not required to be classified as troubled debt restructurings in the Company’s consolidated financial statements unless and until such loans would subsequently meet criteria to be classified as such, since acquired loans were recorded at their estimated fair values at the time of the acquisition.

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill and Intangible Assets and Mortgage Servicing Rights	Note 7 – Goodwill and Intangible Assets and Mortgage Servicing Rights The excess of the purchase price in an acquisition over the fair value of net assets acquired consists primarily of goodwill, core deposit intangibles and other identifiable intangibles (primarily related to customer relationships acquired). Goodwill is not amortized but is instead subject to impairment tests on at least an annual basis. Core deposit intangibles, which arise from value ascribed to the deposit base of a bank acquired, have estimated finite lives and are amortized on an accelerated basis to expense over a 10-year period. The other intangibles, which represent value ascribed to financial advisor books of business purchased in 2016 in a private transaction, have estimated finite lives and are amortized on a straight-line basis to expense over their weighted average life (of approximately 12 years for 2016). Management periodically reviews the carrying value of its long-lived and intangible assets to determine if any impairment has occurred, in which case an impairment charge would be recorded as an expense in the period of impairment, or whether changes in circumstances have occurred that would require a revision to the remaining useful life which would impact expense prospectively. In making such determination, management evaluates whether there are any adverse qualitative factors indicating that an impairment may exist, as well as the performance, on an undiscounted basis, of the underlying operations or assets which give rise to the intangible. The Company’s annual assessments indicated no impairment charge on goodwill or core deposit intangible was required for 2015 or the first nine months of 2016.

At each reporting date, impairment is assessed based on estimated fair value using estimated prepayment speeds of the underlying mortgage loans serviced and stratifications based on the risk characteristics of the underlying loans serviced (predominantly loan type and note interest rate). A valuation allowance is established through a charge to earnings (which would be included in mortgage income, net, in the consolidated income statements) to the extent the amortized cost of the mortgage servicing rights exceeds the estimated fair value by stratification. If it is later determined that all or a portion of the temporary impairment no longer exists for a stratification, the valuation is reduced through a recovery to earnings, though not beyond the net amortized cost carried. An other-than-temporary impairment (i.e. recoverability is considered remote when considering interest rates and loan payoff activity) is recognized as a write-down of the MSR asset and the related valuation allowance (to the extent a valuation allowance is available) and then against earnings. A direct write-down permanently reduces the carrying value of the MSR asset and valuation allowance, precluding subsequent recoveries. The following table shows the estimated future amortization expense for amortizing intangible assets. The projections are based on existing asset balances, the current interest rate environment and prepayment speeds as of the September 30, 2016. The actual amortization expense the Company recognizes in any given period may be significantly different depending upon acquisition or sale activities, changes in interest rates, prepayment speeds, market conditions, regulatory requirements and events or circumstances that indicate the carrying amount of an asset may not be recoverable.

The joint venture note was secured by the building, bore a fixed rate of 5.81% and required monthly principal and interest payments until its maturity on June 1, 2016. In April of 2016, this note was refinanced with Nicolet National Bank and is therefore eliminated through the consolidation process. The FHLB advance bears a fixed rate, requires interest-only monthly payment, and has a maturity in February 2018. The weighted average rates of FHLB advances was 1.17% and 0.83% at September 30, 2016 and December 31, 2015, respectively. FHLB advances are collateralized by a blanket lien on qualifying first mortgages, home equity loans, multi-family loans and certain farmland loans which totaled approximately $297.8 million and $154.3 million at September 30, 2016 and December 31, 2015, respectively.

Subordinated Borrowings [Abstract]
Junior Subordinated Debentures	Note 9 – Junior Subordinated Debentures The Company’s carrying value of junior subordinated debentures was $24.6 million at September 30, 2016 and $12.5 million at December 31, 2015. In July 2004 Nicolet Bankshares Statutory Trust I (the “Statutory Trust”), issued $6.0 million of guaranteed preferred beneficial interests (“trust preferred securities”) that qualify asTier 1 capital under Federal Reserve Board guidelines. All of the common securities of the Statutory Trust are owned by the Company. The proceeds from the issuance of the common securities and the trust preferred securities were used by the Statutory Trust to purchase $6.2 million of junior subordinated debentures of the Company, which pay an 8% fixed rate. Interest on these debentures is current. The debentures may be redeemed in part or in full, on or after July 15, 2009 at par plus any accrued but unpaid interest. The maturity date of the debenture, if not redeemed, is July 15, 2034. As part of the 2013 acquisition of Mid-Wisconsin Financial Services, Inc., the Company assumed $10.3 million of junior subordinated debentures related to $10.0 million of issued trust preferred securities. The trust preferred securities and the debentures mature on December 15, 2035 and have a floating rate of the three-month LIBOR plus 1.43% adjusted quarterly. Interest on these debentures is current. The debentures may be called at par in part or in full, on or after December 15, 2010 or within 120 days of certain events. At acquisition in April 2013 the debentures were recorded at a fair value of $5.8 million, with the discount being accreted to interest expense over the remaining life of the debentures. At September 30, 2016, the carrying value of these junior debentures was $6.5 million, and the $6.2 million carrying value of related trust preferred securities qualifies as Tier 1 capital. As part of the 2016 acquisition of Baylake, the Company assumed $16.6 million of junior subordinated debentures related to $16.1 million of issued trust preferred securities. The trust preferred securities and the debentures mature on September 30, 2036 and have a floating rate of three-month LIBOR plus 1.35% adjusted quarterly. Interest on these debentures is current. The debentures may be redeemed on any interest payment date at par in part or in full, on or after June 30, 2011. At acquisition in April 2016 the debentures were recorded at fair value of $11.8 million, with the discount being accreted to interest expense over the remaining life of the debentures. At September 30, 2016, the carrying value of these junior debentures was $11.9 million, and the $11.4 million carrying value of related trust preferred securities qualifies as Tier 1 capital.

Subordinated Notes [Abstract]
Subordinated Notes	Note 10 – Subordinated Notes In 2015 the Company placed an aggregate of $12 million in subordinated Notes in private placements with certain accredited investors. All Notes were issued with 10-year maturities, have a fixed annual interest rate of 5% payable quarterly, are callable on or after the fifth anniversary of their respective issuances dates, and qualify for Tier 2 capital for regulatory purposes. The $0.2 million debt issuance costs associated with the $12 million Notes are being amortized on a straight line basis over the first five years, representing the no-call periods, as additional interest expense. As of September 30, 2016 and December 31, 2015, respectively, the $0.1 million and $0.2 million, of unamortized debt issuance costs remain and are reflected as a deduction to the carrying value of the outstanding Notes.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Note 11 – Fair Value Measurements As provided for by accounting standards, the Company records and/or discloses financial instruments on a fair value basis. These financial assets and financial liabilities are measured at fair value in three levels, based on the markets in which the assets and liabilities are traded and the observability of the assumptions used to determine fair value. These levels are: Level 1 - quoted market prices in active markets for identical assets or liabilities that a company has the ability to access at the measurement date; Level 2 - inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly; Level 3 – significant unobservable inputs for the asset or liability, which are typically based on an entity’s own assumptions, as there is little, if any, related market activity. In instances where the fair value measurement is based on inputs from different levels, the level within which the entire fair value measurement will be categorized is based on the lowest level input that is significant to the fair value measurement in its entirety; this assessment of the significance of an input requires management judgment. Disclosure of the fair value of financial instruments, whether recognized or not recognized in the balance sheet, is required for those instruments for which it is practicable to estimate that value, with the exception of certain financial instruments and all nonfinancial instruments as provided for by the accounting standards. For financial instruments recognized at fair value in the consolidated balance sheets, the fair value disclosure requirements also apply. Fair value (i.e. the price that would be received in an orderly transaction that is not a forced liquidation or distressed sale at the measurement date), among other things, is based on exit price versus entry price, should include assumptions about risk such as nonperformance risk in liability fair values, and is a market-based measurement versus an entity-specific measurement. The following table presents the balances of assets and liabilities measured at fair value on a recurring basis for the periods presented. One security classified as Level 3 was purchased for $0.6 million during the first quarter of 2016.

Where quoted market prices on securities exchanges are available, the investment is classified as Level 1. Level 1 investments primarily include exchange-traded equity securities available for sale. If quoted market prices are not available, fair value is generally determined using prices obtained from independent pricing vendors who use pricing models (with typical inputs including benchmark yields, reported trades for similar securities, issuer spreads or relationship to other benchmark quoted securities), or discounted cash flows, and are classified as Level 2. Examples of these investments include mortgage-related securities and obligations of state, county and municipals. Finally, in certain cases where there is limited activity or less transparency around inputs to the estimated fair value, investments are classified within Level 3 of the hierarchy. Examples of these include private municipal bonds and corporate debt securities, which include trust preferred security investments. At September 30, 2016 and December 31, 2015, it was determined that carrying value was the best approximation of fair value for these Level 3 securities, based primarily on the internal analysis on these securities. The following table presents the Company’s impaired loans and other real estate owned (“OREO”) measured at fair value on a nonrecurring basis for the periods presented. The additions to the Level 3 category were predominantly due to the April 2016 Baylake merger. Measured at Fair Value on a Nonrecurring Basis Fair Value Measurements Using (in thousands) Total Level 1 Level 2 Level 3 September 30, 2016: Impaired loans $ 20,484 $ - $ - $ 20,484 OREO 2,189 - - 2,189 December 31, 2015: Impaired loans $ 3,566 $ - $ - $ 3,566 OREO 367 - - 367 The following is a description of the valuation methodologies used by the Company for the items noted in the table above, including the general classification of such instruments in the fair value hierarchy. For individually evaluated impaired loans, the amount of impairment is based upon the present value of expected future cash flows discounted at the loan’s effective interest rate, the estimated fair value of the underlying collateral for collateral-dependent loans, or the estimated liquidity of the note. For OREO, the fair value is based upon the estimated fair value of the underlying collateral adjusted for the expected costs to sell.

Accounting Policies [Abstract]
General	General In the opinion of management, the accompanying unaudited consolidated financial statements contain all adjustments necessary to present fairly Nicolet Bankshares, Inc. (the “Company”) and its subsidiaries, consolidated balance sheets, statements of income, comprehensive income, changes in stockholders’ equity and cash flows for the periods presented, and all such adjustments are of a normal recurring nature. All material intercompany transactions and balances are eliminated. The results of operations for the interim periods are not necessarily indicative of the results to be expected for the entire year. These interim consolidated financial statements have been prepared according to the rules and regulations of the Securities and Exchange Commission and, therefore, certain information and footnote disclosures normally presented in accordance with generally accepted accounting principles in the United States of America (“U.S. GAAP”) have been omitted or abbreviated. These consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and footnotes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2015.
Critical Accounting Policies and Estimates	Critical Accounting Policies and Estimates Preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying disclosures. These estimates are based on management’s best knowledge of current events and actions the Company may undertake in the future. Estimates are used in accounting for, among other items, the allowance for loan losses, useful lives for depreciation and amortization, fair value of financial instruments, deferred tax assets, uncertain income tax positions and contingencies. Estimates that are particularly susceptible to significant change for the Company include the determination of the allowance for loan losses, the assessment of deferred tax assets and liabilities, and the valuation of loans acquired in acquisitions; therefore, these are critical accounting policies. Factors that may cause sensitivity to the aforementioned estimates include but are not limited to: external market factors such as market interest rates and employment rates, changes to operating policies and procedures, changes in applicable banking regulations, and changes to deferred tax estimates. Actual results may ultimately differ from estimates, although management does not generally believe such differences would materially affect the consolidated financial statements in any individual reporting period presented. There have been no material changes or developments with respect to the assumptions or methodologies that the Company uses when applying what management believes are critical accounting policies and developing critical accounting estimates as disclosed in the Company’s Annual Report on Form 10-K for the year ended December 31, 2015.
Recent Accounting Developments Adopted	Recent Accounting Developments Adopted The Company has implemented all new accounting pronouncements that are in effect and that may impact its consolidated financial statements or results of operations.
Operating Segment	Operating Segment While the chief decision makers monitor the revenue streams of the various products and services, and evaluate costs, balance sheet positions and quality, all such products, services and activities are directly or indirectly related to the business of community banking, with no regular, formal or material segment delineations. Operations are managed and financial performance is evaluated on a company-wide basis, and accordingly, all the financial service operations are considered by management to be aggregated in one reportable operating segment.
Reclassifications	Reclassifications Certain amounts in the 2015 consolidated financial statements have been reclassified to conform to the 2016 presentation.

When computing earnings per share for an interim period, the denominator is based on the weighted-average shares outstanding during the interim period, and not on an annualized weighted-average basis. Accordingly, the sum of the quarters' earnings per share data will not necessarily equal the year to date earnings per share data.

[1]	Cumulative quarterly per share performance may not equal annual per share totals due to the effects of the amount and timing of capital increases. When computing earnings per share for an interim period, the denominator is based on the weighted-average shares outstanding during the interim period, and not on an annualized weighted-average basis. Accordingly, the sum of the quarters' earnings per share data will not necessarily equal the year to date earnings per share data.
