Accordingly, the sum of the quarters' earnings per share data will not necessarily equal the year to date earnings per share data.

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 the consolidated balance sheets, statements of income, comprehensive income, changes in stockholders’ equity and cash flows of Nicolet Bankshares, Inc. (the “Company” or “Nicolet”) and its subsidiaries, for the periods presented, and all such adjustments are of a normal recurring nature. All material intercompany transactions and balances have been 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, 2017. 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, valuation of loans in acquisition transactions, useful lives for depreciation and amortization, fair value of financial instruments, other-than-temporary impairment calculations, valuation of 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 determination and assessment of deferred tax assets and liabilities, and the valuation of loans acquired in acquisition transactions; 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 or tax 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, 2017. Recent Accounting Developments Adopted In May 2017, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2017-09, Compensation – Stock Compensation (Topic 718) In January 2017, the FASB issued ASU 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts In January 2016, the FASB issued ASU 2016-01, Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606) . Operating Segment While the chief-operating 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 2017 consolidated financial statements have been reclassified to conform to the 2018 presentation.

Business Combinations [Abstract]
Acquisition	Note 2 – Acquisition On April 28, 2017, the Company consummated its merger with First Menasha Bancshares, Inc. (“First Menasha”) pursuant to the Agreement and Plan of Merger by and between the Company and First Menasha dated November 3, 2016, (the “Merger Agreement”), whereby First Menasha was merged with and into the Company, and The First National Bank-Fox Valley, the wholly owned commercial bank subsidiary of First Menasha serving the Fox Valley area of Wisconsin, was merged with and into Nicolet National Bank (the “Bank”). The system integration was completed, and five branches of First Menasha opened on May 1, 2017, as Nicolet National Bank branches, expanding its presence in Calumet and Winnebago Counties, Wisconsin. The Company closed one of its Calumet County locations concurrently with the First Menasha merger. The purpose of the merger was to continue Nicolet’s interest in strategic growth, consistent with its plan to improve profitability through efficiency, leverage the strengths of each bank across the combined customer base, and add shareholder value. With the merger, Nicolet became the leading community bank to serve the Fox Valley area of Wisconsin. Pursuant to the Merger Agreement, the final purchase price consisted of issuing 1,309,885 shares of the Company’s common stock (given the final stock-for-stock exchange ratio of 3.126 except for First Menasha shares owned by the Company immediately prior to the time of the merger), for common stock consideration of $62.2 million (based on $47.52 per share, the volume weighted average closing price of the Company’s common stock over the preceding 20 trading day period) plus cash consideration of $19.3 million. Approximately $0.2 million in direct stock issuance costs for the merger were incurred and charged against additional paid-in capital. Upon consummation, the Company added $480 million in assets, $351 million in loans, $375 million in deposits, $4 million in core deposit intangible, and $41 million of goodwill. The Company accounted for the transaction under the acquisition method of accounting, and thus, the financial position and results of operations of First Menasha 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 estimated fair values at the date of acquisition.

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 common share are 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 Six Months Ended (In thousands, except per share data) 2018 2017 2018 2017 Net income attributable to Nicolet Bankshares, Inc. $ 9,737 $ 8,328 $ 19,314 $ 14,536 Weighted average common shares outstanding 9,639 9,516 9,702 9,053 Effect of dilutive common stock awards 331 476 330 468 Diluted weighted average common shares outstanding 9,970 9,992 10,032 9,521 Basic earnings per common share* $ 1.01 $ 0.88 $ 1.99 $ 1.61 Diluted earnings per common share* $ 0.98 $ 0.83 $ 1.93 $ 1.53 *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. For the three and six months ended June 30, 2018, options to purchase approximately 0.1 million shares are excluded from the calculation of diluted earnings per common share as the effect of their exercise would have been anti-dilutive. There was no anti-dilutive effect of options outstanding for the three and six months ended June 30, 2017.

Stock-based Compensation	Note 4 – Stock-based Compensation The Company may grant stock options and restricted stock under its stock-based compensation plans to certain officers, employees and directors. At June 30, 2018, approximately 145,000 shares were available for grant under these stock-based compensation plans. A Black-Scholes model is utilized to estimate the fair value of stock option grants, while 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 Black-Scholes model for valuing stock option grants for the six months ended June 30, 2018 and 2017, respectively, were as follows. Six Months Ended Six Months Ended Dividend yield 0 % 0 % Expected volatility 25 % 25 % Risk-free interest rate 2.48 % 2.13 % Expected average life 7 years 7 years Weighted average per share fair value of options $ 17.60 $ 15.44 Activity in the Company’s Stock Incentive Plans is summarized in the following tables: Stock Options Option Shares Outstanding Weighted Weighted Aggregate Outstanding – December 31, 2017 1,643,255 $ 39.82 Granted 10,000 54.06 Exercise of stock options * (44,161 ) 21.79 Forfeited (3,500 ) 42.32 Outstanding – June 30, 2018 1,605,594 $ 40.39 7.8 $ 23,805 Exercisable – June 30, 2018 531,506 $ 31.48 6.4 $ 12,558 * 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. No such shares were surrendered to the Company for the six months ended June 30, 2018. Intrinsic value represents the amount by which the fair market value of the underlying stock exceeds the exercise price of the stock options. The intrinsic value of options exercised for the six months ended June 30, 2018 and 2017 was approximately $1.4 million and $1.8 million, respectively. Restricted Stock Weighted Restricted Outstanding – December 31, 2017 $ 34.26 30,920 Granted 56.01 3,000 Vested * 28.89 (7,404 ) Forfeited - - Outstanding – June 30, 2018 $ 38.23 26,516 * The terms of the restricted stock agreements permit the surrender of shares to the Company upon vesting in order to satisfy applicable tax withholding requirements at the minimum statutory withholding rate, and accordingly, 1,615 shares were surrendered during the six months ended June 30, 2018. The Company recognized approximately $2.3 million and $0.9 million of stock-based compensation expense during the six months ended June 30, 2018 and 2017, respectively, associated with its common stock awards. As of June 30, 2018, there was approximately $14.7 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. The Company recognized a tax benefit of approximately $0.2 million for both the six months ended June 30, 2018 and 2017, respectively, for the tax impact of stock option exercises and vesting of restricted stock.

Such securities are no longer reflected as securities AFS. As a result of this accounting change, the Company recognized a cumulative-effect adjustment at adoption from accumulated other comprehensive income to retained earnings of approximately $0.9 million in the consolidated statement of stockholders’ equity for the net of tax impact of the unrealized gain on equity securities as of the date of adoption and recognized a gain of approximately $330,000 for the six months ended June 30, 2018, in the consolidated statements of income for the change in fair value on equity securities since adoption. In addition, the approximately $3.1 million current fair value of equity securities is now reflected within other investments on the consolidated balance sheets rather than as securities AFS. Prior periods have not been restated for the impact of this accounting change. See Note 1 for additional information on this new accounting standard. The following table represents gross unrealized losses and the related estimated fair value of investment securities available for sale, aggregated by investment category and length of time individual securities have been in a continuous unrealized loss position.

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 six-month periods ended June 30, 2018 or 2017. The amortized cost and fair value of securities AFS by contractual maturity at June 30, 2018 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; as this is particularly inherent in mortgage-backed securities, these securities are not included in the maturity categories below.

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. Grade 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. Grade 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. Grade 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 nonaccrual loans are considered to be categorized in this rating, regardless of collateral sufficiency. Grade 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. Grade 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.

Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill and Other Intangibles and Mortgage Servicing Rights	Note 7 – Goodwill and Other Intangibles and Mortgage Servicing Rights Management periodically reviews the carrying value of its 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 quarterly assessment indicated no impairment charge on goodwill, core deposit intangibles or customer list intangibles was required for the year ended December 31, 2017 or the six months ended June 30, 2018.

At each reporting date, impairment is assessed based on an 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). No valuation allowance or impairment charge was recorded for the year ended December 31, 2017 or the six months ended June 30, 2018. See Note 9 for additional information on the fair value of the MSR asset. The following table shows the estimated future amortization expense for amortizing intangible assets and the MSR asset. The projections are based on existing asset balances, the current interest rate environment and prepayment speeds as of the June 30, 2018. 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.

Fair Value Measurements

Fair Value Measurements	6 Months Ended

Fair Value Disclosures [Abstract]
Fair Value Measurements	Note 9 – Fair Value Measurements Fair value represents the estimated price at which an orderly transaction to sell an asset or transfer a liability would take place between market participants at the measurement date under current market conditions (i.e., an exit price concept), and is a market-based measurement versus an entity-specific measurement. 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. Recurring basis fair value measurements: The following table presents the balances of assets and liabilities measured at fair value on a recurring basis for the periods presented. (in thousands) Fair Value Measurements Using Measured at Fair Value on a Recurring Basis: Total Level 1 Level 2 Level 3 June 30, 2018: U.S. government agency securities $ 26,350 $ - $ 26,350 $ - State, county and municipals 166,899 - 166,768 131 Mortgage-backed securities 143,250 - 143,250 - Corporate debt securities 65,476 - 57,025 8,451 Securities AFS $ 401,975 $ - $ 393,393 $ 8,582 Other investments (equity securities) * $ 3,053 $ 3,053 $ - $ - December 31, 2017: U.S. government agency securities $ 26,209 $ - $ 26,209 $ - State, county and municipals 184,044 - 183,386 658 Mortgage-backed securities 155,532 - 155,529 3 Corporate debt securities 36,797 - 28,307 8,490 Equity securities * 2,571 2,571 - - Securities AFS $ 405,153 $ 2,571 $ 393,431 $ 9,151 * Effective January 1, 2018, the Company adopted ASU 2016-01, which requires equity securities with readily determinable fair values to be measured at fair value with changes in the fair value recognized through net income. As a result, the approximately $3.1 million current fair value of equity securities is now reflected within other investments on the consolidated balance sheets compared to securities AFS at December 31, 2017. Prior periods have not been restated for the impact of this accounting change. See Note 1 for additional information on this new accounting standard and see Note 5 for additional information on the impact to securities AFS. The following is a description of the valuation methodologies used by the Company for the securities AFS and equity securities measured at fair value on a recurring basis, as noted in the tables above. Where quoted market prices on securities exchanges are available, the investments are classified as Level 1. Level 1 investments primarily include exchange-traded equity securities. 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 U.S. government agency securities, mortgage-backed securities, obligations of state, county and municipals, and certain corporate debt securities. 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 June 30, 2018 and December 31, 2017, 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 changes in the Level 3 securities AFS measured at fair value on a recurring basis: (in thousands) Six Months Ended Year Ended Level 3 Fair Value Measurements: June 30, 2018 December 31, 2017 Balance at beginning of year $ 9,151 $ 9,108 Acquired balance - 189 Paydowns/Sales/Settlements (569 ) (146 ) Balance at end of period $ 8,582 $ 9,151 Nonrecurring basis fair value measurements: The following table presents the Company’s assets measured at fair value on a nonrecurring basis for the periods presented, aggregated by 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) June 30, 2018: Impaired loans $ 13,844 $ - $ - $ 13,844 Other real estate owned (“OREO”) 1,230 - - 1,230 MSR asset 4,414 - - 4,414 December 31, 2017: Impaired loans $ 17,058 $ - $ - $ 17,058 OREO 1,294 - - 1,294 MSR asset 4,097 - - 4,097 The following is a description of the valuation methodologies used by the Company for the items noted in the table above. 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. To estimate the fair value of the MSR asset, the underlying serviced loan pools are stratified by interest rate tranche and term of the loan, and a valuation model is used to calculate the present value of the expected future cash flows for each stratum. The valuation model incorporates assumptions that market participants would use in estimating future net servicing income, such as costs to service, a discount rate, ancillary income, default rates and losses, and prepayment speeds. Although some of these assumptions are based on observable market data, other assumptions are based on unobservable estimates of what market participants would use to measure fair value.

Revenue from Contract with Customer [Abstract]
Revenue Recognition	Note 10 – Revenue Recognition As of January 1, 2018, the Company adopted ASU 2014-09 (Topic 606) using the modified retrospective approach. The adoption of the guidance had no material impact on the measurement, timing, or recognition of revenue; however, additional disclosures have been added in accordance with the ASU. See Note 1 for additional information on this new accounting standard. Topic 606 does not apply to revenue associated with financial instruments, including revenue from loans and securities. In addition, certain noninterest income categories such as gains or losses associated with mortgage servicing rights, derivatives, and income from bank owned life insurance are not within the scope of the new guidance. The main types of revenue contracts within the scope of Topic 606 include trust services income, brokerage fee income, service charges on deposit accounts, card interchange income, and certain other noninterest income. These contracts are discussed in detail below: Trust services and brokerage fee income Service charges on deposit accounts Card interchange income Other noninterest income

Accounting Policies [Abstract]
General	General In the opinion of management, the accompanying unaudited consolidated financial statements contain all adjustments necessary to present fairly the consolidated balance sheets, statements of income, comprehensive income, changes in stockholders’ equity and cash flows of Nicolet Bankshares, Inc. (the “Company” or “Nicolet”) and its subsidiaries, for the periods presented, and all such adjustments are of a normal recurring nature. All material intercompany transactions and balances have been 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, 2017.
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, valuation of loans in acquisition transactions, useful lives for depreciation and amortization, fair value of financial instruments, other-than-temporary impairment calculations, valuation of 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 determination and assessment of deferred tax assets and liabilities, and the valuation of loans acquired in acquisition transactions; 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 or tax 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, 2017.

Operating Segment	Operating Segment While the chief-operating 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.

Such securities are no longer reflected as securities AFS. As a result of this accounting change, the Company recognized a cumulative-effect adjustment at adoption from accumulated other comprehensive income to retained earnings of approximately $0.9 million in the consolidated statement of stockholders’ equity for the net of tax impact of the unrealized gain on equity securities as of the date of adoption and recognized a gain of approximately $330,000 for the six months ended June 30, 2018, in the consolidated statements of income for the change in fair value on equity securities since adoption. In addition, the approximately $3.1 million current fair value of equity securities is now reflected within other investments on the consolidated balance sheets rather than as securities AFS. Prior periods have not been restated for the impact of this accounting change. See Note 1 for additional information on this new accounting standard.

[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.

[1]	Effective January 1, 2018, the Company adopted ASU 2016-01, which requires equity securities with readily determinable fair values to be measured at fair value with changes in the fair value recognized through net income.Such securities are no longer reflected as securities AFS. As a result of this accounting change, the Company recognized a cumulative-effect adjustment at adoption from accumulated other comprehensive income to retained earnings of approximately $0.9 million in the consolidated statement of stockholders' equity for the net of tax impact of the unrealized gain on equity securities as of the date of adoption and recognized a gain of approximately $330,000 for the six months ended June 30, 2018, in the consolidated statements of income for the change in fair value on equity securities since adoption. In addition, the approximately $3.1 million current fair value of equity securities is now reflected within other investments on the consolidated balance sheets rather than as securities AFS. Prior periods have not been restated for the impact of this accounting change. See Note 1 for additional information on this new accounting standard.

[1]	Effective January 1, 2018, the Company adopted ASU 2016-01, which requires equity securities with readily determinable fair values to be measured at fair value with changes in the fair value recognized through net income. As a result, the approximately $3.1 million current fair value of equity securities is now reflected within other investments on the consolidated balance sheets compared to securities AFS at December 31, 2017. Prior periods have not been restated for the impact of this accounting change. See Note 1 for additional information on this new accounting standard and see Note 5 for additional information on the impact to securities AFS.
