Accounting Policies [Abstract]
BASIS OF PRESENTATION	NOTE 1 – BASIS OF PRESENTATION The unaudited consolidated financial statements of County Bancorp, Inc. (the “Company”) and its subsidiaries have been prepared, in the opinion of management, to reflect all adjustments necessary for a fair presentiation of the financial position, results of operations, and cash flows for the interim period. The results of operations for the three and six months ended June 30, 2016 may not necessarily be indicative of the results to be expected for the year ending December 31, 2016, or for any other period. Management of the Company is required to make estimates and assumptions which affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements, as well as the reported amounts of income and expenses during the reported periods. Actual results could differ significantly from those estimates. These unaudited interim financial statements have been prepared in conformity with U.S. generally accepted accounting principles (“GAAP”). Certain information in footnote disclosure normally included in financial statements prepared in accordance with GAAP has been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). These financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2015. The Company qualifies as an “emerging growth company” under the Jumpstart Our Business Startups Act (the “JOBS Act”). Section 107 of the JOBS Act provides that an emerging growth company can take advantage of the extended transition period provided in Section 7(a)(2)(B) of the Securities Act of 1933, as amended (the “Securities Act”), for complying with new or revised accounting standards. As an emerging growth company, the Company can delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. The Company elected to take advantage of the benefits of this extended transition period. Significant Accounting Policies In addition to the assumptions and methodologies that the Company used to apply significant accounting policies and develop significant estimates as disclosed in the Company’s Annual Report on Form 10-K for the year ended December 31, 2015, the following policies have been added: Business Combinations and Valuation of Loans Acquired in Business Combinations: We account for acquisitions under Financial Accounting Standards Board (“FASB”) ASC Topic 805, Business Combinations, which requires the use of the acquisition method of accounting. Assets acquired and liabilities assumed in a business combination are recorded at estimated fair value on their purchase date. As provided for under GAAP, management has up to 12 months following the date of the acquisition to finalize the fair values of acquired assets and assumed liabilities, where it was not possible to estimate the acquisition date fair value upon consummation. Management finalized the fair values of acquired assets and assumed liabilities within this 12-month period and management considers such values to be the fair value. In particular, the valuation of acquired loans involves significant estimates, assumptions and judgments based on information available as of the acquisition date. Substantially all loans acquired in the transaction are evaluated either individually or in pools of loans with similar characteristics; since the estimated fair value of acquired loans includes a credit consideration, no carryover of any previously recorded allowance for loan losses is recorded at acquisition. A number of factors are considered in determining the estimated fair value of purchased loans including, among other things, the remaining life of the acquired loans, estimated prepayments, estimated loss ratios, estimated value of the underlying collateral, estimated holding periods, contractual interest rates compared to market interest rates, and net present value of cash flows expected to be received. In determining the fair value of acquired loans, management calculates a nonaccretable difference (the credit mark component of the acquired loans) and an accretable difference (the market rate or yield component of the acquired loans). The nonaccretable difference is the difference between the undiscounted contractually required payments and the undiscounted cash flows expected to be collected in accordance with management’s determination of the fair value. Subsequent decreases to the expected cash flows will generally result in a provision for loan losses. Subsequent increases in cash flows will result in a reversal of the provision for loan losses to the extent of prior charges and then an adjustment to accretable yield, and nonaccretable difference which would have a positive impact on interest income. The accretable yield on acquired loans is the difference between the expected cash flows and the initial investment in the acquired loans. The accretable yield is recognized into earnings using the effective yield method over the term of the loans. Management separately monitors the acquired loan portfolio and periodically reviews loans contained within this portfolio against the factors and assumptions used in determining the fair value. Goodwill and Core Deposit Intangible: Management will periodically review 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. Given that the Fox River Valley acquisition took place during the second quarter of 2016, there was no impairment charge to goodwill or core deposit intangible at June 30, 2016. The net book value of core deposit intangible was $1.7 million and $0 at June 30, 2016 and December 31, 2015, respectively and is included on the consolidated balance sheets.

Earnings Per Share [Abstract]
EARNINGS PER SHARE	NOTE 3 – EARNINGS PER SHARE Earnings per common share is computed using the two-class method. Basic earnings per common share is computed by dividing net income by the weighted-average number of common shares outstanding during the applicable period. Diluted earnings per share is computed using the weighted-average number of shares determined for the basic earnings per common share plus the dilutive effect of share-based compensation using the treasury stock method.

The following table shows the gross unrealized losses and fair value of the Company’s investments with unrealized losses that are not deemed to be other-than-temorarily impaired, aggregated by investment category and length of time that individual securities have been in a continuous unrealized loss position at June 30, 2016 and December 31, 2015: Less Than 12 Months 12 Months or Greater Total Fair Unrealized Fair Unrealized Fair Unrealized Value Losses Value Losses Value Losses (dollars in thousands) June 30, 2016 U.S. government and agency securities $ — $ — $ — $ — $ — $ — Municipal securities 2,063 (2 ) 610 (1 ) 2,673 (3 ) Mortgage-backed securities 8,434 (52 ) — — 8,434 (52 ) Asset-backed securities 3,846 (156 ) — — 3,846 (156 ) $ 14,343 $ (210 ) $ 610 $ (1 ) $ 14,953 $ (211 ) December 31, 2015 U.S. government and agency securities $ 2,003 $ — $ — $ — $ 2,003 $ — Municipal securities 14,153 (53 ) 711 (5 ) 14,864 (58 ) Mortgage-backed securities 11,291 (86 ) 2,039 (32 ) 13,330 (118 ) $ 27,447 $ (139 ) $ 2,750 $ (37 ) $ 30,197 $ (176 ) The unrealized loss on the investments at June 30, 2016 and December 31, 2015 was due to normal fluctuations and pricing inefficiencies. The contractual terms of the investments do not permit the issuers to settle the securities at a price less than the amortized cost basis of the investment. Because the Company does not intend to sell the investments and it is not more-likely-than-not that the Company will be required to sell the investments before recovery of the amortized cost basis, which may be maturity, the Company does not consider these investments to be other-than-temporarily impaired at June 30, 2016 and December 31, 2015.

Interest income recognized on total impaired loans for the six months ended June 30, 2016 and for the year ended December 31, 2015 amounted to approximately $0.5 million and $1.7 million, respectively. For nonaccrual loans included in impaired loans, the interest income that would have been recognized had those loans been performing in accordance with their original terms would have been approximately $0.8 million and $1.7 million for the six months ended June 30, 2016 and for the year ended December 31, 2015, respectively. Troubled Debt Restructurings The Company has allocated approximately $0.5 million and $0.7 million of specific reserves to customers whose loan terms have been modified in troubled debt restructurings (“TDR”) at June 30, 2016 and December 31, 2015, respectively. The Company has no additional lending commitments at June 30, 2016 and December 31, 2015 to customers with outstanding loans that are classified as TDRs. A TDR on nonaccrual status is classified as a nonaccrual loan until evaluation supports reasonable assurance of repayment and of performance according to the modified terms of the loan. Once this assurance is reached, the TDR is classified as a restructured loan. There were no unfunded commitments on these loans at June 30, 2016, and December 31, 2015. The following table presents the TDRs by loan class at June 30, 2016 and December 31, 2015: Non-Accrual Restructured and Accruing Total (dollars in thousands) June 30, 2016 Agricultural loans $ 6,322 $ — $ 6,322 Commercial real estate loans 2,008 2,383 4,391 Commercial loans 1,671 1,200 2,871 Residential real estate loans 94 — 94 Installment and consumer other — — — Total $ 10,095 $ 3,583 $ 13,678 December 31, 2015 Agricultural loans $ 1,337 $ — $ 1,337 Commercial real estate loans 744 486 1,230 Commercial loans 235 124 359 Residential real estate loans — — — Installment and consumer other — — — Total $ 2,316 $ 610 $ 2,926 Credit Quality Indicators The Company categorizes loans into risk categories based on relevant information about the ability of the borrowers to service their debt, such as current financial information, historical payment experience, credit documentation, public information and current economic trends, among other factors. The Company analyzes agricultural, commercial, and commercial real estate loans individually by classifying the credits as to credit risk. The process of analyzing loans for changes in risk rating is ongoing through routine monitoring of the portfolio and annual internal credit reviews for credits with total exposure in excess of $300,000. The Company uses the following definitions for credit risk ratings: Sound. Credits classified as sound show very good probability of ongoing ability to meet and/or exceed obligations. Acceptable. Credits classified as acceptable show a good probability of ongoing ability to meet and/or exceed obligations. Satisfactory. Credits classified as satisfactory show fair probability of ongoing ability to meet and/or exceed obligations. Low Satisfactory . Credits classified as low satisfactory show fair probability of ongoing ability to meet and/or exceed obligations. Low satisfactory credits may be newer or have a less established track record of financial performance, inconsistent earnings, or may be going through an expansion. Watch. Credits classified as watch show some questionable probability of ongoing ability to meet and/or exceed obligations. Special Mention. Credits classified as special mention show potential weaknesses that deserve management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loans or of the institution’s credit position at some future date. Substandard . Credits classified as substandard generally have well-defined weaknesses that jeopardize the repayment of the debt. They have a distinct possibility that a loss will be sustained if the deficiencies are not corrected. Doubtful. Credits classified as doubtful have all the weaknesses inherent in those classified as substandard with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable. The Company categorizes residential real estate, installment and consumer other loans as satisfactory at the time of origination based on information obtained as to the ability of the borrower(s) to service their debt, such as current financial information, employment status and history, historical payment experience, credit scores and type and amount of collateral among other factors. The Company updates relevant information on these types of loans at the time of refinance, troubled debt restructuring or other indications of financial difficulty, downgrading as needed using the same category descriptions as for agricultural, commercial, and commercial real estate loans. In addition, the Company further considers current payment status as an indicator of which risk category to assign the borrower. The greater the level of deteriorated risk as indicated by a loan’s assigned risk category, the greater the likelihood a loss will occur in the future. If the loan is impaired, then the loan loss reserves for the loan are recorded at the loss level of impairment. If the loan is not impaired, then its loan loss reserves are determined by the application of a loss rate that increases with risk in accordance with the allowance for loan loss analysis. Based on the most recent analysis performed by management, the risk category of loans by class of loans is as follows as of June 30, 2016 and December 31, 2015: As of June 30, 2016 Sound/ Acceptable/ Satisfactory/ Low Satisfactory Watch Special Mention Substandard Total Loans (dollars in thousands) Agricultural loans $ 473,008 $ 44,356 $ 19,667 $ 17,350 $ 554,381 Commercial real estate loans 230,808 21,134 8,509 8,005 268,456 Commercial loans 65,699 6,920 3,278 6,275 82,172 Residential real estate loans 51,154 3,754 — 94 55,002 Installment and consumer other 299 — — — 299 Total $ 820,968 $ 76,164 $ 31,454 $ 31,724 $ 960,310 As of December 31, 2015 Sound/ Acceptable/ Satisfactory/ Low Satisfactory Watch Special Mention Substandard Total Loans (dollars in thousands) Agricultural loans $ 441,528 $ 30,762 $ 6,306 $ 20,724 $ 499,320 Commercial real estate loans 139,061 13,956 4,527 4,197 161,741 Commercial loans 40,496 5,468 533 5,481 51,978 Residential real estate loans 27,514 4,572 2,545 — 34,631 Installment and consumer other 518 1 — — 519 Total $ 649,117 $ 54,759 $ 13,911 $ 30,402 $ 748,189

LOAN SERVICING RIGHTS	NOTE 6 – LOAN SERVICING RIGHTS Loans serviced for others are not included in the accompanying consolidated balance sheets. The risks inherent in servicing assets relate primarily to changes in prepayments that result from shifts in interest rates. The unpaid principal balances of mortgage and other loans serviced for others were approximately $557.1 million and $495.9 million at June 30, 2016 and December 31, 2015, respectively. The fair value of these rights were approximately $11.8 million and $10.7 million at June 30, 2016 and December 31, 2015, respectively. The fair value of servicing rights was determined using an assumed discount rate of 10 percent and prepayment speeds primarily ranging from 4 percent to 9 percent, depending upon the stratification of the specific right, and nominal credit losses. The following summarizes servicing rights capitalized and amortized, along with the aggregate activity in related valuation allowances: June 30, December 31, 2016 2015 (dollars in thousands) Loan servicing rights: Balance, beginning of period $ 8,145 $ 7,746 Additions 3,025 3,731 Disposals (1,056 ) (1,421 ) Amortization (1,003 ) (1,911 ) Balance, end of period $ 9,111 $ 8,145

Goodwill And Intangible Assets Disclosure [Abstract]
GOODWILL AND CORE DEPOSIT INTANGIBLE	NOTE 7 – GOODWILL AND CORE DEPOSIT INTANGIBLE The excess of the purchase price in an acquisition over the fair value of net assets acquired consists primarily of goodwill and core deposit intangibles. Goodwill is not amortized but is instead subject to impairment tests on at least an annual basis. Core deposit intangibles, which arise from value ascribed to the deposit base of a bank acquired, have estimated finite lives and are amortized on an accelerated basis to expense over a 66-month period. Management will periodically review the carrying value of its long-lived and intangible assets to determine if any impairment has occurred, in which case an impairment charge would be recorded as an expense in the period of impairment, or whether changes in circumstances have occurred that would require a revision to the remaining useful life which would impact expense prospectively. In making such determination, management evaluates whether there are any adverse qualitative factors indicating that an impairment may exist, as well as the performance, on an undiscounted basis, of the underlying operations or assets which give rise to the intangible. There was no impairment charge to goodwill or core deposit intangible at June 30, 2016. Goodwill : Goodwill resulted from the acquisition of Fox River Valley on May 13, 2016. The carrying amount of goodwill was $5.0 million at June 30, 2016 and $0 million at December 31, 2015. See Note 2 for additional information on the acquisition. Core deposit intangible: Core deposit intangibles, primarily related acquired customer relationships, are amortized over their estimated finite lives. The core deposit intangible related to the Fox River Valley acquisition had a gross carrying amount of $1.8 million. Amortization on core deposit intangibles was $54 thousand for the three and six months ended June 30, 2016. There was no core deposit intangible and no amoritzation recorded on the balance sheet and statement of operations for the year ended Decembger 31, 2015. See Note 2 for additional information on the acquisition.

Debt Disclosure [Abstract]
SUBORDINATED DEBENTURES	NOTE 9 – SUBORDINATED DEBENTURES In connection with the merger with Fox River Valley, the Company also acquired Fox River Valley’s wholly-owned subsidiary Fox River Valley Capital Trust I, a Delaware statutory trust (the “Trust”), which issued capital securities that qualify for Tier II capital of the Company. The Company assumed the $3.6 million of floating rate, junior subordinated debentures, of which the Company owns $0.1 million. The debentures are non-voting, mandatorily redeemable in 2033 and guaranteed by the Company. The distribution rate payable on the debentures is cumulative and payable quarterly in arrears. The Company has the right, subject to events of default, to defer payments of interest on the debentures at any time by extending the interest payment period not exceeding 20 consecutive quarters with respect to each deferral period, provided that no extension period may extend beyond the redemption or maturity date of the debentures. Interest is current through the most recent due date of May 30, 2016. The Trust may redeem some or all of the capital securities, at par, with 30 days advance notice, on or after November 30, 2008, but only on May 30 or November 30 of any given year, and only in a minimum amount of $500,000 and in increments of $10,000 thereafter, or the full amount of the capital securities. The Trust may redeem all of the capital securities at any time upon the occurrence and during the continuation of a Tax Event, an Investment Company Event or a Capital Treatment Event (each as defined in the trust agreement for the Trust), at any time within 90 days following such event. The notes carry an interest rate equal to 5-year LIBOR plus 3.40%, which resets every five years. The current rate is equal to 4.855% through November 30, 2018. Interest payments are due quarterly.

EQUITY INCENTIVE PLAN	NOTE 10 – EQUITY INCENTIVE PLAN On June 21, 2016 the shareholders approved the 2016 Long Term Incentive Plan (the “2016 Plan”), replacing the Company’s 2012 Equity Incentive Compensation Plan (the “2012 Plan”). In accordance with the 2016 Plan and the 2012 Plan, the Company may grant options to purchase shares of common stock and issue restricted stock to its directors, officers, and employees. Both qualified and non-qualified stock options and restricted stock may be granted and issued, respectively, under the 2016 Plan and 2012 Plan. As of June 30, 2016, no options or shares of restricted stock have been granted under the 2016 Plan. The exercise price of each option equals the market price of the Company’s stock on the date of grant and an option’s maximum term is ten years. Vesting periods range from one to five years from the date of grant. The restricted stock vesting periods range from one to five years from the date of issuance. The status of the Company’s 2012 Plan and changes in the 2012 Plan as of June 30, 2016 are as follows: June 30, 2016 Number of Options Weighted-Average Exercise Price Aggregate Intrinsic Value (1) (dollars in thousands except option and per share data) Outstanding, beginning of year 351,931 $ 13.71 Granted 45,097 19.83 Exercised (6,943 ) 13.44 Forfeited/expired — — Outstanding, end of period 390,085 $ 14.43 $ 2,391 Options exercisable at period-end 262,570 $ 12.54 $ 2,122 Weighted-average fair value of options granted during the period (2) $ 4.87 (1) The aggregate intrinsic value of a stock option in the table above represents the total pre-tax intrinsic value (the amount by which the current market value of the underlying stock exceeds the exercise price of the option) that would have been received by the option holders had all option holders exercised their options on June 30, 2016. This amount changes based on changes in the market value of the Company’s stock. (2) The fair value (present value of the estimated future benefit to the option holder) of each option grant is estimated on the date of grant using the Black-Scholes option pricing model. Activity in restricted stock awards (“RSA”) as of June 30, 2016 is as follows: June 30, 2016 RSAs Weighted Average Grant Price Outstanding, beginning of year 46,621 $ 14.92 Granted 13,757 19.77 Vested (11,560 ) 12.05 Forfeited/expired — — Outstanding, end of period 48,818 $ 16.96 For the six months ended June 30, 2016 and 2015, share-based compensation expense, including options and restricted stock awards, applicable to the 2012 Plan was $236.0 thousand and $157.0 thousand, respectively. As of June 30, 2016, unrecognized share-based compensation expense related to nonvested options and restricted stock awards amounted to $1.2 million and is expected to be recognized over a weighted average period of 2.24 years.

REGULATORY MATTERS

REGULATORY MATTERS	6 Months Ended

Regulatory Capital Requirements [Abstract]
REGULATORY MATTERS	NOTE 11 – REGULATORY MATTERS The Company (on a consolidated basis) and the Bank are each subject to various regulatory capital requirements administered by the federal and state 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’s and the Bank’s financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Company and the 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 the Bank to maintain minimum amounts and ratios (set forth in the following table) of total, Tier 1 and Tier 1 Common Equity capital to risk-weighted assets, and of Tier 1 capital to average assets, as such terms are defined in the regulations. Management believes, as of June 30, 2016 and December 31, 2015, that the Company and the Bank met all capital adequacy requirements to which they were subject. As of June 30, 2016, the Bank’s capital ratios met those required to be considered as well capitalized under the regulatory framework for prompt corrective action. To be categorized as well capitalized the Bank must maintain minimum total risk-based, Tier 1 risk-based, Tier 1 Common Equity risk-based, and Tier 1 leverage ratios as set forth in the following tables. The Company’s and the Bank’s actual capital amounts and ratios are presented in the following table: Actual Minimum For Capital Adequacy Purposes (a) Minimum To Be Well Capitalized Under Prompt Corrective Action Provisions: Amount Ratio Amount Ratio Amount Ratio (dollars in thousands) June 30, 2016 Total Capital (to risk weighted assets): Consolidated $ 145,270 13.84 % $ 90,545 8.625 % No t Bank 140,695 13.41 % 90,521 8.625 % $ 104,952 10.00 % Tier 1 Capital (to risk weighted assets): Consolidated 133,967 12.76 % 69,549 6.625 % Not applicable Bank 129,392 12.33 % 69,530 6.625 % 83,961 8.00 % Tier 1 Capital (to average assets): Consolidated 133,967 11.73 % 45,681 4.00 % Not applicable Bank 129,392 11.34 % 45,655 4.00 % 57,069 5.00 % Tier 1 Common Equity Ratio (to risk weighted assets): Consolidated 110,560 10.53 % 53,802 5.125 % Not applicable Bank 129,392 12.33 % 53,788 5.125 % 68,218 6.50 % December 31, 2015 Total Capital (to risk weighted assets): Consolidated $ 144,495 17.51 % $ 66,013 8.00 % Not applicable Bank 125,354 15.19 % 66,000 8.00 % $ 82,500 10.00 % Tier 1 Capital (to risk weighted assets): Consolidated 134,175 16.26 % 49,510 6.00 % Not applicable Bank 115,036 13.94 % 49,500 6.00 % 66,000 8.00 % Tier 1 Capital (to average assets): Consolidated 134,175 15.49 % 34,656 4.00 % Not applicable Bank 115,036 13.29 % 34,635 4.00 % 43,294 5.00 % Tier 1 Common Equity Ratio (to risk weighted assets): Consolidated 98,803 11.97 % 37,132 4.50 % Not applicable Bank 115,036 13.94 % 37,125 4.50 % 53,625 6.50 % (a) The ratios for June 30, 2016 include a capital conservation buffer of 0.625%. The rules of the Basel III regulatory capital framework (the “Basel III Capital Rules”), which became effective January 1, 2015, revised the prompt corrective action requirements by, among other things: (i) introducing a Common Equity Tier 1 ratio requirement at each level (other than critically undercapitalized), with the required Common Equity Tier 1 ratio being 6.5% for “well-capitalized” status; (ii) increasing the minimum Tier 1 capital ratio requirement for each category (other than critically undercapitalized), with the minimum Tier 1 capital ratio for “well-capitalized” status being 8% (compared to the prior ratio of 6%); and (iii) eliminating the former provision that provided that a bank with a composite supervisory rating of 1 may have a 3% Leverage Ratio and still be adequately capitalized. The Basel III Capital Rules do not change the total risk based capital requirement for any prompt corrective action category. The Basel III Capital Rules also implemented a new capital conservation buffer that is added to the minimum requirements for capital adequacy purposes. The capital conservation buffer is subject to a three year phase-in period that began on January 1, 2016 and will be fully phased in on January 1, 2019 at 2.5%. The required phase-in capital conservation buffer during 2016 is 0.625%. At the present time, the ratios for the Company and the Bank are sufficient to meet the fully phased-in conservation buffer.

Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS	NOTE 12 – FAIR VALUE MEASUREMENTS ASC 820-10 defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. A fair value measurement assumes that the transaction to sell the asset or transfer the liability occurs in the principal market for the asset or liability or, in the absence of a principal market, the most advantageous market for the asset or liability. The price in the principal (or most advantageous) market used to measure the fair value of the asset or liability shall not be adjusted for transaction costs. An orderly transaction is a transaction that assumes exposure to the market for a period prior to the measurement date to allow for marketing activities that are usual and customary for transactions involving such assets and liabilities; it is not a forced transaction. Market participants are buyers and sellers in the principal market that are independent, knowledgeable, and both able and willing to transact. ASC 820-10 requires the use of valuation techniques that are consistent with the market approach, the income approach, and/or the cost approach. The market approach uses prices and other relevant information generated by market transactions involving identical or comparable assets and liabilities. The income approach uses valuation techniques to convert future amounts, such as cash flows or earnings, to a single present amount on a discounted basis. The cost approach is based on the amount that currently would be required to replace the service capacity of an asset (replacement cost). Valuation techniques should be consistently applied. Inputs to valuation techniques refer to the assumptions that market participants would use in pricing the asset or liability. Inputs may be observable or unobservable. Observable inputs reflect the assumptions market participants would use in pricing the asset or liability developed based on market data obtained from independent sources. Unobservable inputs reflect the reporting entity’s own assumptions about the assumptions market participants would use in pricing the asset or liability developed based on the best information available in the circumstances. In that regard, ASC 820-10 establishes a fair value hierarchy for valuation inputs that gives the highest priority to quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. The fair value hierarchy is as follows: Level 1—Valuation is based on quoted prices in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date. Level 1 assets and liabilities generally include debt and equity securities that are traded in an active exchange market. Valuations are obtained from readily available pricing sources for market transactions involving identical assets or liabilities. Level 2—Valuation is based on inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. The valuation may be based on quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or inputs that are observable or can be corroborated by observable market data for substantially the full term of the asset or liability. Level 3—Valuation is based on unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Level 3 assets and liabilities include financial instruments whose value is determined using pricing models, discounted cash flow methodologies, or similar techniques, as well as instruments for which determination of fair value requires significant management judgment or estimation. A financial instrument’s categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The following methods and assumptions were used by the Company in estimating the fair value disclosures for financial instruments: Cash and Cash Equivalents and Interest-Bearing Deposits in Banks The carrying amounts of cash and short-term instruments approximate fair values based on the short-term nature of the assets. Fair values of other interest-bearing deposits are estimated using discounted cash flow analyses based on current rates for similar types of deposits. Securities Available for Sale Where quoted prices are available in an active market, the Company classifies the securities within Level 1 of the valuation hierarchy. Securities are defined as both long and short positions. Level 1 securities include highly liquid government bonds and exchange-traded equities. If quoted market prices are not available, the Company estimates fair values using pricing models and discounted cash flows that consider standard input factors such as observable market data, benchmark yields, interest rate volatilities, broker/dealer quotes and credit spreads. Examples of such instruments, which would generally be classified within Level 2 of the valuation hierarchy, include U.S. government and agency securities, corporate bonds and other securities. Mortgage-backed securities are included in Level 2 if observable inputs are available. In certain cases where there is limited activity or less transparency around inputs to the valuation, the Company classifies those securities in Level 3. Loans For variable-rate loans that reprice frequently and with no significant change in credit risk, fair values are based on carrying values. Fair values for certain mortgage loans (e.g., one-to-four family residential), credit card loans, and other consumer loans are based on quoted market prices of similar loans sold in conjunction with securitization transactions, adjusted for differences in loan characteristics. Fair values for other loans (e.g., commercial and agricultural loans) are estimated using discounted cash flow analyses, using interest rates currently being offered for loans with similar terms to borrowers of similar credit quality. Fair values for non-performing loans are estimated using discounted cash flow analyses or underlying collateral values, where applicable. Loans Held for Sale The carrying value of loans held for sale generally approximates fair value based on the short-term nature of the assets. If management identifies a loan held for sale that will ultimately sell at a value less than its carrying value, it is recorded at the estimated value. Loan Servicing Rights Fair value is based on market prices for comparable loan servicing contracts, when available, or alternatively, is based on a valuation model that calculates the present value of estimated future net servicing income. Other Real Estate Owned Loans on which the underlying collateral has been repossessed are adjusted to fair value upon transfer to other real estate owned. Subsequently, other real estate owned is carried at the lower of carrying value or fair value. Fair value is based upon independent market prices, appraised values of the collateral, or management’s estimation of the value of the collateral. Due to the significance of the unobservable inputs, all other real estate owned is classified as Level 3. Deposits The fair values disclosed for demand deposits (e.g., interest and non-interest checking, statement savings, and certain types of money market accounts) are, by definition, equal to the amount payable on demand at the reporting date (i.e., their carrying amounts). The carrying amounts of variable-rate, fixed-term money market accounts and certificates of deposit approximate their fair values at the reporting date. Fair values for fixed-rate certificates of deposit are estimated using a discounted cash flow calculation that applies interest rates currently being offered on certificates to a schedule of aggregated expected monthly maturities on time deposits. Other Borrowings The carrying amounts of federal funds purchased, other borrowings, and other short-term borrowings maturing within 90 days approximate their fair values. Advances from the Federal Home Loan Bank Current market rates for debt with similar terms and remaining maturities are used to estimate fair value of advances from the Federal Home Loan Bank (the “FHLB”). Fair values are estimated using discounted cash flow analyses based on current market rates for similar types of borrowing arrangements. Subordinated Debentures The fair values of these debt instruments utilize a discounted cash flow analysis based on an estimate of current interest rates being offered by instruments with similar terms and credit quality. Since the market for these instruments is limited, the internal evaluation represents a Level 3 measurement and approximates fair value. Accrued Interest The carrying amounts approximate fair value. Commitments to Extend Credit and Standby Letters of Credit As of June 30, 2016 and December 31, 2015, the carrying and fair values of the commitments to extend credit and standby letters of credit are not considered significant. Assets measured at fair value on a recurring basis are summarized below: Level 1 Inputs Level 2 Inputs Level 3 Inputs Total Fair Value (dollars in thousands) June 30, 2016 Securities available for sale: U.S. government and agency securities $ — $ 2,004 $ — $ 2,004 Municipal securities — 43,233 — 43,233 Mortgage-backed securities — 79,953 — 79,953 Asset-backed securities — 3,846 — 3,846 Total assets at fair value $ — $ 129,036 $ — $ 129,036 December 31, 2015 Securities available for sale: U.S. government and agency securities $ — $ 2,003 $ — $ 2,003 Municipal securities — 46,312 — 46,312 Mortgage-backed securities — 34,966 — 34,966 Total assets at fair value $ — $ 83,281 $ — $ 83,281 Certain assets and liabilities are measured at fair value on a nonrecurring basis; that is, they are subject to fair value adjustments in certain circumstances (for example, when there is evidence of impairment).

Accounting Policies [Abstract]
Significant Accounting Policies	Significant Accounting Policies In addition to the assumptions and methodologies that the Company used to apply significant accounting policies and develop significant estimates as disclosed in the Company’s Annual Report on Form 10-K for the year ended December 31, 2015, the following policies have been added: Business Combinations and Valuation of Loans Acquired in Business Combinations: We account for acquisitions under Financial Accounting Standards Board (“FASB”) ASC Topic 805, Business Combinations, which requires the use of the acquisition method of accounting. Assets acquired and liabilities assumed in a business combination are recorded at estimated fair value on their purchase date. As provided for under GAAP, management has up to 12 months following the date of the acquisition to finalize the fair values of acquired assets and assumed liabilities, where it was not possible to estimate the acquisition date fair value upon consummation. Management finalized the fair values of acquired assets and assumed liabilities within this 12-month period and management considers such values to be the fair value. In particular, the valuation of acquired loans involves significant estimates, assumptions and judgments based on information available as of the acquisition date. Substantially all loans acquired in the transaction are evaluated either individually or in pools of loans with similar characteristics; since the estimated fair value of acquired loans includes a credit consideration, no carryover of any previously recorded allowance for loan losses is recorded at acquisition. A number of factors are considered in determining the estimated fair value of purchased loans including, among other things, the remaining life of the acquired loans, estimated prepayments, estimated loss ratios, estimated value of the underlying collateral, estimated holding periods, contractual interest rates compared to market interest rates, and net present value of cash flows expected to be received. In determining the fair value of acquired loans, management calculates a nonaccretable difference (the credit mark component of the acquired loans) and an accretable difference (the market rate or yield component of the acquired loans). The nonaccretable difference is the difference between the undiscounted contractually required payments and the undiscounted cash flows expected to be collected in accordance with management’s determination of the fair value. Subsequent decreases to the expected cash flows will generally result in a provision for loan losses. Subsequent increases in cash flows will result in a reversal of the provision for loan losses to the extent of prior charges and then an adjustment to accretable yield, and nonaccretable difference which would have a positive impact on interest income. The accretable yield on acquired loans is the difference between the expected cash flows and the initial investment in the acquired loans. The accretable yield is recognized into earnings using the effective yield method over the term of the loans. Management separately monitors the acquired loan portfolio and periodically reviews loans contained within this portfolio against the factors and assumptions used in determining the fair value. Goodwill and Core Deposit Intangible: Management will periodically review 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. Given that the Fox River Valley acquisition took place during the second quarter of 2016, there was no impairment charge to goodwill or core deposit intangible at June 30, 2016. The net book value of core deposit intangible was $1.7 million and $0 at June 30, 2016 and December 31, 2015, respectively and is included on the consolidated balance sheets.
