Accounting Policies [Abstract]
NATURE OF BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES	NOTE 1. NATURE OF BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES Nature of Banking Activities and Subsidiaries During 2004, the Company entered into a joint venture, Nicolet Joint Ventures, LLC (the “JV”), with a real estate development and investment firm (the “Firm”) in connection with the selection and development of a site for a new headquarters facility. The Firm is considered a related party, as one of its principals is a Board member and shareholder of the Company. The JV involves a 50% ownership by the Company. See Note 17 for additional disclosures. During 2008, the Company purchased 100% of Brookfield Investment Partners, LLC (“Brookfield Investments”), an investment advisory firm that provides investment strategy and transactional services to financial institutions. Goodwill of $0.8 million was recorded in conjunction with this purchase. In 2013, the Company consummated its acquisition of Mid-Wisconsin Financial Services, Inc. (“Mid-Wisconsin”), whereby Mid-Wisconsin was merged with and into the Company, and Mid-Wisconsin Bank, Mid-Wisconsin’s wholly owned commercial bank subsidiary serving central Wisconsin, was merged with and into the Bank. In 2013, the Company acquired selected assets and assumed selected liabilities of Bank of Wausau through a Federal Deposit Insurance Corporation (“FDIC”) assisted transaction. There was no loss sharing agreement as part of this acquisition. Collectively, the Mid-Wisconsin and Bank of Wausau transactions are referred to as “the 2013 acquisitions.” During late 2016, the Company capitalized Nicolet Advisory Services, LLC (“Nicolet Advisory”), a wholly owned registered investment advisor subsidiary to provide brokerage and investment advisory services to customers. In 2016, the Company consummated its acquisition of Baylake Corp. (“Baylake”), whereby Baylake was merged with and into the Company, and Baylake Bank, Baylake’s wholly owned commercial bank subsidiary serving northeast Wisconsin, was merged with and into the Bank. Goodwill of $65.5 million was recorded in conjunction with this purchase. In 2016, the Company in a private transaction hired a select group of financial advisors and purchased their respective books of business and their operating platform. Goodwill of $0.4 million was recorded in conjunction with this purchase. Collectively, the Baylake and financial advisory transactions are referred to as “the 2016 acquisitions.” See Note 2 for additional disclosures. Through its acquisition of Baylake, the Bank owns a 49.8% indirect interest in United Financial Services, LLC (“UFS, LLC”), a data processing service and e-banking entity, through its 99.2% ownership of United Financial Services, Inc. (“UFS, Inc.”). Collectively, UFS, Inc. and UFS, LLC are referred to as “UFS”. The investment in UFS is carried in other assets under the equity method of accounting, and the Bank’s pro rata share of UFS income is included in noninterest income. Income in equity of UFS recognized by the Bank was $1.0 million for the year ended December 31, 2016. Amounts paid to UFS for data processing services by the Bank were $1.6 million and $0.9 million in 2016 and 2015, respectively. Loans to UFS were $0.2 million at December 31, 2016 compared to none at the end of 2015. The carrying value of the Bank’s investment in UFS was $8.3million at December 31, 2016. Principles of Consolidation Operating Segment: Use of 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. Business Combinations: Business Combinations Cash and Cash Equivalents Securities Available for Sale (“AFS”) Realized gains or losses on securities sales (using the specific identification method) and declines in value judged to be other-than-temporary are included in the consolidated statements of income under gain on sale and write-down of assets, net. Premiums and discounts are amortized or accreted into interest income over the life of the related securities using the effective interest method. Management evaluates investment securities for other-than-temporary impairment on at least an annual basis. A decline in the market value of any investment below amortized cost that is deemed other-than-temporary is charged to earnings for the decline in value deemed to be credit related and a new cost basis in the security is established. The decline in value attributed to non-credit related factors considered temporary in nature is recognized in other comprehensive income. In evaluating other-than-temporary impairment, management considers the length of time and extent to which the fair value has been less than cost, and the financial condition and near-term prospects of the issuer for a period sufficient to allow for any anticipated recovery in fair value in the near term. Other Investments Loans Held for Sale Mortgage Servicing Rights (“MSRs”): Loans and Allowance for Loan Losses (“ALLL”) – Originated Loans Management considers a loan to be impaired when it is probable the Company will be unable to collect all contractual principal and interest payments due in accordance with the terms of the loan agreement. For determining the adequacy of the ALLL, all material loans in nonaccrual status are evaluated for impairment, together with additional loans having impairment risk characteristics. For this purpose, management has defined “material” to be a credit relationship of more than $250,000. 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. Typically, impairment amounts for loans under the scope criteria are charged off when the impairment amount is determined. The ALLL is a reserve for estimated credit losses on individually evaluated loans determined to be impaired as well as estimated credit losses inherent in the loan portfolio. Actual credit losses, net of recoveries, are deducted from the ALLL. Loans are charged off when management believes that the collectability of the principal is unlikely. Subsequent recoveries, if any, are credited to the ALLL. A provision for loan losses, which is a charge against earnings, is recorded to bring the ALLL to a level that, in management’s judgment, is adequate to absorb probable losses in the loan portfolio. The allocation methodology applied by the Company is designed to assess the appropriateness of the ALLL and 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 a 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 total allowance is available to absorb losses from any segment of the loan portfolio. Management believes the ALLL is appropriate at December 31, 2016. The allowance analysis is reviewed by the Board on a quarterly basis in compliance with regulatory requirements. In addition, various regulatory agencies periodically review the ALLL. These agencies may require the Company to make additions to the ALLL based on their judgments of collectability based on information available to them at the time of their examination. Loans and ALLL – Acquired Loans: PCI loans are accounted for under the accounting guidance for loans and debt securities acquired with deteriorated credit quality, found in FASB ASC Topic 310-30, Receivables—Loans and Debt Securities Acquired with Deteriorated Credit Quality Performing acquired loans are accounted for under FASB ASC Topic 310-20, Receivables—Nonrefundable Fees and Other Costs An ALLL is calculated using a methodology similar to that described for originated loans. Performing acquired loans are subsequently evaluated for any required allowance at each reporting date. Such required allowance for each loan pool is compared to the remaining fair value discount for that pool. If greater, the excess is recognized as an addition to the allowance through a provision for loan losses. If less than the discount, no additional allowance is recorded. Charge-offs and losses first reduce any remaining fair value discount for the loan pool and once the discount is depleted, losses are applied against the allowance established for that pool. For PCI loans after acquisition, cash flows expected to be collected are recast for each loan periodically as determined appropriate by management. If the present value of expected cash flows for a loan is less than its carrying value, impairment is reflected by an increase in the ALLL and a charge to the provision for loan losses. If the present value of the expected cash flows for a loan is greater than its carrying value, any previously established ALLL is reversed and any remaining difference increases the accretable yield which will be taken into income over the remaining life of the loan. Loans which were considered troubled debt restructurings by Mid-Wisconsin and Baylake prior to the acquisitions are not required to be classified as troubled debt restructurings in the Company’s consolidated financial statements unless or 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. Credit-Related Financial Instruments Transfers of Financial Assets Premises and Equipment Estimated useful lives of new premises and equipment generally range as follows: Building and improvements 25 – 39 years Leasehold improvements 5 – 15 years Furniture and equipment 3 – 10 years Other Real Estate Owned (“OREO”) Goodwill and Other Intangibles Management periodically reviews the carrying value of its long-lived and intangible assets to determine if any impairment has occurred or whether changes in circumstances have occurred that would require a revision to the remaining useful life, in which case an impairment charge would be recorded as an expense in the period of impairment. 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 other intangibles was required for 2016 or 2015. Bank-owned Life Insurance (“BOLI”): Short-term Borrowings Stock-based Compensation Plans: 2016 2015 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 Income Taxes Amounts provided for income tax expense are based on income reported for financial statement purposes and do not necessarily represent amounts currently payable under tax laws. Deferred income tax assets and liabilities are computed annually for differences between the financial statement and tax bases of assets and liabilities that will result in taxable or deductible amounts in the future based on enacted tax rates applicable to the periods in which the differences are expected to affect taxable income. As changes in tax laws or rates are enacted, deferred tax assets and liabilities are adjusted through the provision for income taxes. Valuation allowances are established when it is more likely than not that a portion of the full amount of the deferred tax asset will not be realized. In assessing the ability to realize deferred tax assets, management considers the scheduled reversal of deferred tax liabilities, projected future taxable income and tax planning strategies. At acquisition, deferred taxes were evaluated in respect to the acquired assets and assumed liabilities (including the acquired net operating losses), and a net deferred tax asset was recorded. Certain limitations within the provisions of the tax code are placed on the amount of net operating losses which can be utilized as part of acquisition accounting rules and were incorporated into the calculation of the deferred tax asset. In addition, a portion of the fair market value discounts on PCI loans which resolved in the first twelve months after the acquisition were disallowed under provisions of the tax code. The Company may also recognize a liability for unrecognized tax benefits from uncertain tax positions. Unrecognized tax benefits represent the differences between a tax position taken or expected to be taken in a tax return and the benefit recognized and measured in the consolidated financial statements. At December 31, 2016, the Company determined it had no significant uncertain tax positions. Interest and penalties related to unrecognized tax benefits are classified as income tax expense.

Business Combinations [Abstract]
ACQUISITIONS	NOTE 2. ACQUISITIONS On April 29, 2016, the Company consummated its merger with 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 the Bank. The system integration was completed, and 21 branches of Baylake opened, on May 2, 2016, as branches of the Bank, expanding its presence into Door, Kewaunee, and Manitowoc Counties, Wisconsin. Concurrently, Nicolet closed one of its Brown County locations at the time of the merger, and closed an additional six branches in the fourth quarter of 2016, bringing the Bank’s footprint to 36 branches as of December 31, 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 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 by 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 the year ended December 31, 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.

As of December 31, 2016, the Company does not consider its AFS securities with unrealized losses to be other-than-temporarily impaired. 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 was a $0.5 million other-than-temporary impairment (related to one private company stock carried in other investments in the consolidated balance sheets) charged to earnings during the fourth quarter of 2016 compared to none in 2015 and 2014. The amortized cost and fair value of AFS securities by contractual maturity at December 31, 2016 are shown below. Maturities may differ from contractual maturities in mortgage-backed securities because the mortgages underlying the securities may be called or prepaid without any penalties; therefore, these securities are not included in the maturity categories in the following summary.

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 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.

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.

Interest of approximately $1.8 million, $0.4 million, and $0.7 million was earned on year-end nonaccrual loans and included in income for each of the years ended December 31, 2016, 2015 and 2014, respectively. In April 2016, the Baylake merger added PCI loans at a fair value of $20.8 million, net of an initial $13.9 million non-accretable mark. Combining the 2013 and 2016 acquisitions, total PCI loans acquired in aggregate were initially recorded at a fair value of $37.5 million on their respective acquisition dates, net of an initial $26.1 million non-accretable mark and a zero accretable mark. At December 31, 2016, $18.8 million of the $37.5 million remain in impaired loans and $0.4 million of acquired loans have subsequently become impaired, bringing acquired impaired loans to $19.2 million, net of a $14.3 million non-accretable mark and a zero accretable mark.

These five loans had a pre-modification balance of $1.3 million and at December 31, 2016, had a balance of $0.8 million. There were no loans which were classified as troubled debt restructurings during the previous twelve months that subsequently defaulted during 2016. As of December 31, 2016 there were no commitments to lend additional funds to debtors whose terms have been modified in troubled debt restructurings. Loans which were considered troubled debt restructurings prior to the acquisitions are not required to be classified as troubled debt restructurings in the Company’s consolidated financial statements unless or 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.

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 other intangibles was required for 2016 or 2015.

Subordinated Borrowings [Abstract]
JUNIOR SUBORDINATED DEBENTURES	NOTE 10. JUNIOR SUBORDINATED DEBENTURES At December 31, 2016 and 2015, the Company’s carrying value of junior subordinated debentures was $24.7 million and $12.5 million, respectively. At December 31, 2016 and 2015, $23.7 million and $12.0 million, respectively, of trust preferred securities qualify as Tier 1 capital. In July 2004, Nicolet Bankshares Statutory Trust I (the “Nicolet Trust”) issued $6.0 million of guaranteed preferred beneficial interests (“trust preferred securities”) in the Company’s junior subordinated deferrable interest debentures that qualify as Tier 1 capital under Federal Reserve Board guidelines. All of the common securities of the Nicolet Trust are owned by the Company. The proceeds from the common securities and trust preferred securities were used by the Nicolet Trust to purchase $6.2 million of junior subordinated debentures (the “debentures”) of the Company. The trust preferred securities and debentures pay an 8% fixed rate. The proceeds received by the Company from the sale of the debentures were used for general purposes, primarily to provide capital to the Bank. The Company has the right to redeem the debentures, in whole or in part, on or after July 15, 2009. If the debentures are redeemed prior to maturity, the redemption price will be the principal amount and any accrued but unpaid interest. The maturity date of the debentures, if not redeemed, is July 15, 2034. Interest on the debentures is current. In April 2013, as part of the Mid-Wisconsin acquisition, the Company assumed $10.3 million of junior subordinated debentures issued in December 2005 by Mid-Wisconsin, related to $10.0 million of trust preferred securities issued by a statutory trust, whose common securities were wholly owned by Mid-Wisconsin. These trust preferred securities and debentures mature on December 15, 2035 and have a floating rate of the three-month LIBOR plus 1.43%, adjusted quarterly. The interest rates were 2.39% and 1.94% as of December 31, 2016 and 2015, respectively. The debentures may be called at par plus any accrued but unpaid interest, in part or in full, on or after December 15, 2010 or within 120 days of certain events. At acquisition the debentures were recorded at an initial fair market value of $5.8 million, with the initial $4.5 million discount being accreted to interest expense over the remaining life of the debentures. The discount accreted during 2016, 2015 and 2014 was approximately $0.2 million each year, bringing the carrying value of the debentures to $6.5 million, $6.3 million and $6.1 million at December 31, 2016, 2015 and 2014, respectively. Interest on the debentures is current. 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 interest rate was 2.35% as of December 31, 2016. 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 December 31, 2016, the carrying value of these junior debentures was $12.0 million. The debentures represent the sole asset of the respective statutory trusts. The statutory trusts are not included in the consolidated financial statements. The net effect of all the documents entered into with the trust preferred securities is that the Company, through payment on its debentures, is liable for the distributions and other payments required on the trust preferred securities.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
EMPLOYEE AND DIRECTOR BENEFIT PLANS	NOTE 12. EMPLOYEE AND DIRECTOR BENEFIT PLANS The Company sponsors two deferred compensation plans, one for certain key management employees and another for directors. Under the management plan, which was amended in 2016, employees designated by the Board of Directors may defer compensation and receive the deferred amounts plus earnings thereon upon termination of employment or at their election. The liability for the cumulative employee contributions and earnings thereon at December 31, 2016 and 2015 totaled approximately $272,000 and $359,000, respectively, and is included in other liabilities in the consolidated balance sheets. Under the director plan participating directors may defer up to 100% of their Board compensation towards the purchase of Company common stock at market prices on a quarterly basis that is held in a Rabbi Trust. During 2016 and 2015, the plan purchased 3,796 and 4,820 shares of Company common stock valued at approximately $138,000 and $143,000, respectively. There were no distributions in 2016. In 2015, common stock valued at approximately $49,000 (and representing 2,670 shares) was distributed. The common stock outstanding and the related director deferred compensation liability are offsetting components of the Company’s equity in the amount of $641,000 at year end 2016 and $502,000 at year end 2015 representing 28,510 shares and 24,561 shares, respectively. The Company sponsors a 401(k) savings plan under which eligible employees may choose to save up to 100% of salary compensation on either a pre-tax or after-tax basis, subject to certain IRS limits. Under the plan, the Company matches 100% of participating employee contributions up to 6% of the participant’s gross compensation. The Company contribution vests over five years. The Company can make additional annual discretionary profit sharing contributions, as determined by the Board of Directors. During 2016, 2015 and 2014, the Company’s 401(k) expense was approximately $1.2 million, $0.9 million and $0.8 million, respectively. During 2016, the plan was amended and participants can no longer elect to buy Company common stock within their 401(k) portfolio. During 2015 participants purchased in the aggregate a net 963 shares of Company common stock valued at approximately $31,000.

STOCK-BASED COMPENSATION	NOTE 13. STOCK-BASED COMPENSATION At December 31, 2016, the Company had three stock-based plans. These plans are administered by a committee of the Board of Directors and provide for the granting of various equity awards in accordance with the plan documents to certain officers, employees and directors of the Company. The Company’s 2002 Stock Incentive Plan initially covered 125,000 shares of the Company’s common stock. The Company, with subsequent shareholder approval, revised this plan to allow for 450,000 additional shares in 2005 and 600,000 additional shares in 2008. A total of 1,175,000 shares have been reserved for potential stock options under the 2002 Plan. The Company also adopted, with subsequent shareholder approval, the 2011 Long Term Incentive Plan covering up to 500,000 shares of the Company’s common stock. The Company, with subsequent shareholder approval, revised this plan to allow for 1,000,000 additional shares in 2016. A total of 1,500,000 shares have been reserved for potential stock-based awards. This plan provides for certain stock-based awards such as, but not limited to, stock options, stock appreciation rights and restricted common stock, as well as cash performance awards. As part of the 2016 Baylake acquisition, the Company assumed sponsorship of the Baylake Corp. 2010 Equity Incentive Plan and also assumed 91,701 stock options issued under such plan. The Company amended the plan to rename it the Nicolet Bankshares, Inc. 2010 Equity Incentive Plan and to provide that no further awards may be granted under this plan. In general, for stock options granted the exercise price will not be less than the fair market value of the Company’s common stock on the date of grant, the options will become exercisable based upon vesting terms determined by the committee, and the options will expire ten years after the date of grant. In general, for restricted stock granted the shares are issued at the fair market value of the Company’s common stock on the date of grant, are restricted as to transfer, but are not restricted as to dividend payments or voting rights, and the transfer restrictions lapse over time, depending upon vesting terms provided for in the grant and contingent upon continued employment. As of December 31, 2016, approximately 1,100,000 shares were available for grant under these plans (collectively the “Stock Incentive Plans”). Activity of the Stock Incentive Plans is summarized in the following tables: Stock Options Option Shares Weighted Exercisable Weighted Balance – December 31, 2013 793,157 $ 17.86 600,846 $ 18.25 Granted 221,000 23.80 Exercise of stock options (39,548 ) 16.01 Forfeited (6,750 ) 16.80 Balance – December 31, 2014 967,859 $ 19.30 630,121 $ 18.24 Granted 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 $ 19.09 Granted 170,500 36.86 Options assumed in acquisition 91,701 21.03 Exercise of stock options* (84,723 ) 20.98 Forfeited (1,456 ) 21.71 Balance – December 31, 2016 922,026 $ 24.39 439,639 $ 19.97 * 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, and accordingly 10,244 shares and 167,779 shares were surrendered in 2016 and 2015, respectively, and no shares surrendered in 2014. Options outstanding at December 31, 2016 are exercisable at option prices ranging from $16.00 – 38.10. There are 301,953 options outstanding in the range from $16.00 - $20.00, 252,989 options outstanding in the range from $20.01 - $25.00, 160,211 options outstanding in the range from $25.01 - $30.00, and 206,873 options outstanding in the range from $30.01 - $38.10. At December 31, 2016, the exercisable options have a weighted average remaining contractual life of approximately five years and a weighted average exercise price of $19.97. Intrinsic value represents the amount by which the fair market value of the underlying stock exceeds the exercise price of the stock options. The total intrinsic value of options exercised in 2016, 2015 and 2014 was approximately $1.3 million, $5.2 million, and $0.2 million, respectively. The total intrinsic value of exercisable shares at December 31, 2016 was approximately $12.2 million.

The Company recognized $1.6 million, $1.2 million and $1.0 million of stock-based employee compensation expense during the years ended December 31, 2016, 2015 and 2014, respectively, associated with its stock equity awards. As of December 31, 2016, there was approximately $4.5 million of unrecognized compensation cost related to equity award grants. The cost is expected to be recognized over the remaining vesting period of approximately four years.

STOCKHOLDERS' EQUITY	NOTE 14. STOCKHOLDERS’ EQUITY During 2014, a common stock repurchase program was authorized to use up to $12 million to repurchase up to 625,000 shares of Nicolet common stock as an alternative use of capital. On July 21, 2015, a modification to the current stock repurchase program was approved, adding $6 million more to repurchase up to 175,000 more shares of its common stock. On January 17, 2017, the stock repurchase program was modified again, adding $12 million more to repurchase up to 250,000 more shares of its common stock. This brings the total authorization to $30 million to repurchase up to 1,050,000 shares of outstanding common stock. Through December 31, 2016, $14.2 million was used to repurchase and cancel 518,609 shares at a weighted average price of $27.31 per share including commissions. On April 29, 2016, in connection with its acquisition of Baylake, the Company issued 4,344,243 shares of its common stock for consideration of $163.3 million, and recorded $1.2 million consideration for assumed stock options. Approximately $0.3 million of common stock issuance expenses related to the transaction were incurred and charged against additional paid in capital. In connection with the financial advisor business acquisition that completed April 1, 2016, the Company issued $2.6 million in common stock consideration. On February 24, 2016, Nicolet’s common stock moved off the OTCBB and began trading on the Nasdaq Capital Market, also under the trading symbol of “NCBS.”

At December 31, 2016 and 2015, no valuation allowance was determined to be necessary. At December 31, 2016, the Company had a federal and state net operating loss carryforward of $5.3 million and $23.4 million, respectively. Of these amounts, the entire $5.3 million of federal net operating loss carryover and $21.0 million of the state net operating loss carryover were the result of the Company’s mergers with Mid-Wisconsin and Baylake. Both the federal and state net operating loss carryovers resulting from the mergers have been included in the IRC section 382 limitation calculation and are being limited to the overall amount expected to be realized. The full $2.4 million state net operating loss carried over from the Company’s regular operations is expected to be utilized over the next 17 years and will not expire. The Company’s federal income tax returns are open and subject to examination from the 2013 tax return year and forward. The years open to examination by state and local government authorities varies by jurisdiction.

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	NOTE 16. COMMITMENTS AND CONTINGENCIES The Company is party to financial instruments with off-balance-sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit, financial guarantees, and standby letters of credit. They involve, to varying degrees, elements of credit risk in excess of amounts recognized on the consolidated balance sheets. The Company’s exposure to credit loss in the event of nonperformance by the other party to the financial instruments for commitments to extend credit and standby letters of credit is represented by the contractual notional amount of those instruments. The Company uses the same credit policies in making commitments and issuing letters of credit as they do for on-balance-sheet instruments. A summary of the contract or notional amount of the Company’s exposure to off-balance-sheet risk as of December 31 is as follows: (in thousands) 2016 2015 Financial instruments whose contract amounts represent credit risk: Commitments to extend credit $ 554,980 $ 302,591 Financial letters of credit 12,444 2,610 Standby letters of credit 4,898 4,314 Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. Credit card commitments are generally unsecured. Financial and standby letters of credit are conditional commitments issued to guarantee the performance of a customer to a third party. Financial letters of credit are issued specifically to facilitate commerce and typically result in the commitment being drawn on when the underlying transaction is consummated between the customer and the third party, while standby letters of credit generally are contingent upon the failure of the customer to perform according to the terms of the underlying contract with the third party. Both of these guarantees are primarily issued to support public and private borrowing arrangements and, generally, have terms of one year or less. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers. The Company holds collateral, which may include accounts receivable, inventory, property, equipment, and income-producing properties, supporting those commitments if deemed necessary. For standby letters of credit, in the event the customer does not perform in accordance with the terms of the agreement with the third-party, the Company would be required to fund the commitment. The maximum potential amount of future payments the Company could be required to make is represented by the contractual amount. If the commitment is funded, the Company would be entitled to seek recovery from the customer. At December 31, 2016 and 2015, no amounts have been recorded as liabilities for the Company’s potential obligations under these guarantees. The Company has federal funds accommodations with other financial institutions where funds may be borrowed on a short-term basis at the market rate in effect at the time of the borrowing. The total federal funds accommodations as of December 31, 2016 and 2015 were $75 million. At December 31, 2016 and 2015, the Company had no outstanding balance on these lines. In the normal course of business, the Company is involved in various legal proceedings. In the opinion of management, any liability resulting from such proceedings would not have a material adverse effect on the consolidated financial statements.

Related Party Transactions [Abstract]
RELATED PARTY TRANSACTIONS	NOTE 17. RELATED PARTY TRANSACTIONS The Company conducts transactions, in the normal course of business, with its directors and officers, including companies in which they have a beneficial interest. It is the Company’s policy to comply with federal regulations that require that these transactions with directors and executive officers be made on substantially the same terms as those prevailing at the time made for comparable transactions to other persons. Related party loans totaled approximately $54.0 million and $25.4 million at December 31, 2016 and 2015, respectively. During 2004, the Company entered into a joint venture (50% ownership by the Company) with the Firm in connection with the building of the Company’s new headquarters facility. The Firm is considered a related party, as one of its principals is a Board member and shareholder of the Company. During 2016, 2015 and 2014, the Bank incurred approximately $1.1 million, $1.2 million and $1.2 million, respectively, in rent expense to the joint venture. In August 2011, the Company opened a new branch location in a facility which is leased from an entity owned by the Firm on terms considered by management to be arms-length and incurred less than $120,000 annually of rent expense on this facility during 2016, 2015, and 2014. In October 2013, the Company entered into a lease for a new branch location in a facility owned by a different member of the Company’s Board on terms considered by management to be arms-length and incurred less than $120,000 annually of rent expense on this facility during 2016, 2015, and 2014. In February 2016, the Company entered into a lease agreement for a location owned by a relative of a management team member. The building is to be used by a subsidiary of the Company on terms considered to be arms-length and incurred less than $120,000 of lease expense for the partial year. This amount is expected to exceed $120,000 in future years based on a full year of lease expense. This same individual received approximately $420,000 for his services to the Company during 2016. In addition, a payment of approximately $400,000 was made to another relative of the management team member for his services to the Company.

Banking and Thrift [Abstract]
REGULATORY CAPITAL REQUIREMENTS AND RESTRICTIONS OF DIVIDENDS	NOTE 19. REGULATORY CAPITAL REQUIREMENTS AND RESTRICTIONS OF DIVIDENDS The Company (on a consolidated basis) and the Bank are subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company and Bank’s financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company and Bank must meet specific capital guidelines that involve quantitative measures of their assets, liabilities and certain off-balance-sheet items as calculated under regulatory accounting practices. The capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk-weightings, and other factors. Prompt corrective action provisions are not applicable to bank holding companies. Quantitative measures established by regulation to ensure capital adequacy require the Company and Bank to maintain minimum amounts and ratios of Total, Tier 1 and common equity Tier 1 (“CET1”) capital (as defined in the regulations) to risk-weighted assets (as defined), and Tier 1 capital (as defined) to average assets (as defined). Management believes, as of December 31, 2016 and 2015, that the Company and the Bank met all capital adequacy requirements to which they are subject. As of December 31, 2016 and 2015, the most recent notifications from the regulatory agencies categorized the Bank as well-capitalized under the regulatory framework for prompt corrective action. To be categorized as well-capitalized, an institution must maintain minimum Total risk-based, Tier 1 risk-based, CET1 risk-based and Tier 1 leverage ratios as set forth in the following table. There are no conditions or events since these notifications that management believes have changed the Bank’s category. The Company’s and the Bank’s actual regulatory capital amounts and ratios as of December 31, 2016 and 2015 are presented in the following table. Actual For Capital Adequacy To Be Well Capitalized (dollars in thousands) Amount Ratio (1) Amount Ratio (1) Amount Ratio (1) As of December 31, 2016: Company Total risk-based capital $ 249,723 13.9 % $ 144,195 8.0 % Tier 1 risk-based capital 226,018 12.5 108,146 6.0 Common equity Tier 1 capital 202,313 11.2 81,110 4.5 Leverage 226,018 10.3 87,566 4.0 Bank Total risk-based capital $ 217,682 12.1 % $ 144,322 8.0 % $ 180,403 10.0 % Tier 1 risk-based capital 205,862 11.4 108,242 6.0 144,322 8.0 Common equity Tier 1 capital 205,862 11.4 81,181 4.5 117,262 6.5 Leverage 205,862 9.4 87,329 4.0 109,161 5.0 As of December 31, 2015: Company Total risk-based capital $ 140,691 14.8 % $ 75,972 8.0 % Tier 1 risk-based capital 118,535 12.5 56,979 6.0 Common equity Tier 1 capital 94,346 9.9 42,697 4.5 Leverage 118,535 10.0 47,627 4.0 Bank Total risk-based capital $ 122,206 13.1 % $ 74,903 8.0 % $ 93,629 10.0 % Tier 1 risk-based capital 111,899 12.0 56,178 6.0 74,903 8.0 Common equity Tier 1 capital 111,899 12.0 42,133 4.5 60,859 6.5 Leverage 111,899 9.5 47,036 4.0 58,794 5.0 (1) The Total risk-based capital ratio is defined as Tier 1 capital plus tier 2 capital divided by total risk-weighted assets. The Tier 1 risk-based capital ratio is defined as Tier 1 capital divided by total risk-weighted assets. CET1 risk-based capital ratio is defined as Tier 1 capital, with deductions for goodwill and other intangible assets (other than mortgage servicing assets), net of associated deferred tax liabilities, and limitations on the inclusion of deferred tax assets, mortgage servicing assets and investments in other financial institutions, in each case as provided further in the rules, divided by total risk-weighted assets. The Leverage ratio is defined as Tier 1 capital divided by the most recent quarter’s average total assets as adjusted. (2) Prompt corrective action provisions are not applicable at the bank holding company level. A source of income and funds for the Company are dividends from the Bank. Dividends declared by the Bank that exceed the retained net income for the most current year plus retained net income for the preceding two years must be approved by Federal regulatory agencies. During the third quarter of 2016, the Bank requested approval from the regulatory agencies to pay a $15 million special dividend from Bank surplus and it was approved. At December 31, 2016, the Bank could pay dividends of approximately $1.1 million without seeking regulatory approval.

FAIR VALUE OF FINANCIAL INFORMA

Fair Value Disclosures [Abstract]
FAIR VALUE OF FINANCIAL INFORMATION	NOTE 20. FAIR VALUE OF FINANCIAL INFORMATION 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 consolidated 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: Fair Value Measurements Using Measured at Fair Value on a Recurring Basis: Total Level 1 Level 2 Level 3 (in thousands) U.S. government sponsored enterprises $ 1,963 $ - $ 1,963 $ - State, county and municipals 187,243 - 186,717 526 Mortgage-backed securities 159,129 - 159,076 53 Corporate debt securities 12,169 - 3,640 8,529 Equity securities 4,783 4,783 - - Securities AFS, December 31, 2016 $ 365,287 $ 4,783 $ 351,396 $ 9,108 U.S. government sponsored enterprises $ 294 $ - $ 294 $ - State, county and municipals 105,021 - 104,495 526 Mortgage-backed securities 61,464 - 61,464 - Corporate debt securities 1,140 - - 1,140 Equity securities 4,677 4,677 - - Securities AFS, December 31, 2015 $ 172,596 $ 4,677 $ 166,253 $ 1,666 The following table presents the changes in Level 3 assets measured at fair value on a recurring basis during the years ended December 31: Securities AFS Level 3 Fair Value Measurements ($ in thousands): 2016 2015 (in thousands) Balance at beginning of year $ 1,666 $ 796 Purchases 2,250 920 Acquired balance 5,192 - Sales/settlements - (50 ) Balance at end of year $ 9,108 $ 1,666 The following is a description of the valuation methodologies used by the Company for the items noted in the tables above. 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 corporate debt securities. At December 31, 2016 and 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 the corporate debt securities. The following table presents the Company’s collateral-dependent impaired loans and OREO measured at fair value on a nonrecurring basis as of December 31, 2016 and 2015, aggregated by the level in the fair value hierarchy within which those measurements fall. Fair Value Measurements Using Measured at Fair Value on a Nonrecurring Basis: Total Level 1 Level 2 Level 3 (in thousands) December 31, 2016: Impaired loans $ 19,217 $ - $ - $ 19,217 OREO 2,059 - - 2,059 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.

Securities Available For Sale ("AFS")	Securities Available for Sale (“AFS”) Realized gains or losses on securities sales (using the specific identification method) and declines in value judged to be other-than-temporary are included in the consolidated statements of income under gain on sale and write-down of assets, net. Premiums and discounts are amortized or accreted into interest income over the life of the related securities using the effective interest method. Management evaluates investment securities for other-than-temporary impairment on at least an annual basis. A decline in the market value of any investment below amortized cost that is deemed other-than-temporary is charged to earnings for the decline in value deemed to be credit related and a new cost basis in the security is established. The decline in value attributed to non-credit related factors considered temporary in nature is recognized in other comprehensive income. In evaluating other-than-temporary impairment, management considers the length of time and extent to which the fair value has been less than cost, and the financial condition and near-term prospects of the issuer for a period sufficient to allow for any anticipated recovery in fair value in the near term.

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 other intangibles was required for 2016 or 2015.

Income Taxes	Income Taxes Amounts provided for income tax expense are based on income reported for financial statement purposes and do not necessarily represent amounts currently payable under tax laws. Deferred income tax assets and liabilities are computed annually for differences between the financial statement and tax bases of assets and liabilities that will result in taxable or deductible amounts in the future based on enacted tax rates applicable to the periods in which the differences are expected to affect taxable income. As changes in tax laws or rates are enacted, deferred tax assets and liabilities are adjusted through the provision for income taxes. Valuation allowances are established when it is more likely than not that a portion of the full amount of the deferred tax asset will not be realized. In assessing the ability to realize deferred tax assets, management considers the scheduled reversal of deferred tax liabilities, projected future taxable income and tax planning strategies. At acquisition, deferred taxes were evaluated in respect to the acquired assets and assumed liabilities (including the acquired net operating losses), and a net deferred tax asset was recorded. Certain limitations within the provisions of the tax code are placed on the amount of net operating losses which can be utilized as part of acquisition accounting rules and were incorporated into the calculation of the deferred tax asset. In addition, a portion of the fair market value discounts on PCI loans which resolved in the first twelve months after the acquisition were disallowed under provisions of the tax code. The Company may also recognize a liability for unrecognized tax benefits from uncertain tax positions. Unrecognized tax benefits represent the differences between a tax position taken or expected to be taken in a tax return and the benefit recognized and measured in the consolidated financial statements. At December 31, 2016, the Company determined it had no significant uncertain tax positions. Interest and penalties related to unrecognized tax benefits are classified as income tax expense.

Loans and Allowance for Loan Losses ("ALLL")	Loans and Allowance for Loan Losses (“ALLL”) – Originated Loans Management considers a loan to be impaired when it is probable the Company will be unable to collect all contractual principal and interest payments due in accordance with the terms of the loan agreement. For determining the adequacy of the ALLL, all material loans in nonaccrual status are evaluated for impairment, together with additional loans having impairment risk characteristics. For this purpose, management has defined “material” to be a credit relationship of more than $250,000. 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. Typically, impairment amounts for loans under the scope criteria are charged off when the impairment amount is determined. The ALLL is a reserve for estimated credit losses on individually evaluated loans determined to be impaired as well as estimated credit losses inherent in the loan portfolio. Actual credit losses, net of recoveries, are deducted from the ALLL. Loans are charged off when management believes that the collectability of the principal is unlikely. Subsequent recoveries, if any, are credited to the ALLL. A provision for loan losses, which is a charge against earnings, is recorded to bring the ALLL to a level that, in management’s judgment, is adequate to absorb probable losses in the loan portfolio. The allocation methodology applied by the Company is designed to assess the appropriateness of the ALLL and 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 a 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 total allowance is available to absorb losses from any segment of the loan portfolio. Management believes the ALLL is appropriate at December 31, 2016. The allowance analysis is reviewed by the Board on a quarterly basis in compliance with regulatory requirements. In addition, various regulatory agencies periodically review the ALLL. These agencies may require the Company to make additions to the ALLL based on their judgments of collectability based on information available to them at the time of their examination.
Acquired Loans
Accounts, Notes, Loans and Financing Receivable [Line Items]
Loans and Allowance for Loan Losses ("ALLL")	Loans and ALLL – Acquired Loans: PCI loans are accounted for under the accounting guidance for loans and debt securities acquired with deteriorated credit quality, found in FASB ASC Topic 310-30, Receivables—Loans and Debt Securities Acquired with Deteriorated Credit Quality Performing acquired loans are accounted for under FASB ASC Topic 310-20, Receivables—Nonrefundable Fees and Other Costs An ALLL is calculated using a methodology similar to that described for originated loans. Performing acquired loans are subsequently evaluated for any required allowance at each reporting date. Such required allowance for each loan pool is compared to the remaining fair value discount for that pool. If greater, the excess is recognized as an addition to the allowance through a provision for loan losses. If less than the discount, no additional allowance is recorded. Charge-offs and losses first reduce any remaining fair value discount for the loan pool and once the discount is depleted, losses are applied against the allowance established for that pool. For PCI loans after acquisition, cash flows expected to be collected are recast for each loan periodically as determined appropriate by management. If the present value of expected cash flows for a loan is less than its carrying value, impairment is reflected by an increase in the ALLL and a charge to the provision for loan losses. If the present value of the expected cash flows for a loan is greater than its carrying value, any previously established ALLL is reversed and any remaining difference increases the accretable yield which will be taken into income over the remaining life of the loan. Loans which were considered troubled debt restructurings by Mid-Wisconsin and Baylake prior to the acquisitions are not required to be classified as troubled debt restructurings in the Company’s consolidated financial statements unless or 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.
