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 months ended March 31, 2016 may not necessarily be indicative of the results to be expected for the entire fiscal year. 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 rules and regulations of the Securities and Exchange Commission (“SEC”). These financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s 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.

ACQUISITIONS

Business Combinations [Abstract]
ACQUISITIONS	On November 19, 2015, the Company entered into an Agreement and Plan of Merger (the “Merger Agreement”) by and among the Company, County Acquisition LLC, a wholly-owned subsidiary of the Company, and Fox River Valley Bancorp, Inc., a Wisconsin corporation (“Fox River Valley”), pursuant to which the Company will acquire Fox River Valley and its wholly-owned bank subsidiary, The Business Bank. Under the terms of the Merger Agreement, the Company will acquire 100% of Fox River Valley’s outstanding common stock for aggregate consideration of $28.9 million, subject to downward adjustment under certain circumstances. The purpose of the merger is for strategic reasons beneficial to the Company. The acquisition is consistent with its growth plans to expand into the desirable markets of Appleton and Green Bay, Wisconsin and diversify its loan portfolio to decrease its agricultural concentration. The Company believes it is well-positioned to achieve stronger financial performance and enhance shareholder value through synergies of the combined operations. Fox River Valley’s shareholders approved the Merger Agreement on March 17, 2016, and the merger transaction is appropriately not reflected in the Company’s March 31, 2016 financial statements. The Company received the required regulatory approvals in April 2016, and the merger is expected to close on May 13, 2016, and is subject to customary closing conditions.

Earnings Per Share [Abstract]
EARNINGS PER SHARE	NOTE 3 – EARNINGS PER SHARE Earnings per common share ("EPS") 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. For the Three Months Ended March 31, 2016 2015 Net income from continuing operations $ 2,176 $ 2,526 Less: preferred stock dividends including SBLF 102 118 Income available to common shareholders for basic EPS $ 2,074 $ 2,408 Average number of common shares issued 6,561 6,193 Less: weighted average treasury shares 422 410 Less: weighted average nonvested equity incentive plan shares 360 348 Weighted average number of common shares outstanding 5,779 5,435 Effect of dilutive options 109 120 Weighted average number of common shares outstanding used to calculate diluted earnings per common share 5,888 5,555

Expected maturities will differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties. Amortized Fair Cost Value (dollars in thousands) March 31, 2016 Due in one year or less $ 10,588 $ 10,611 Due from one to five years 32,179 32,433 Due from five to ten years 2,698 2,761 Due after ten years — — Mortgage-backed securities 33,189 33,887 $ 78,654 $ 79,692 December 31, 2015 Due in one year or less $ 5,005 $ 5,017 Due from one to five years 39,329 39,400 Due from five to ten years 3,854 3,898 Due after ten years — — Mortgage-backed securities 34,728 34,966 $ 82,916 $ 83,281 There were no security sales for the three months ended March 31, 2016 and 2015, respectively. 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 March 31, 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) March 31, 2016 U.S. government and agency securities $ — $ — $ — $ — $ — $ — Municipal securities 3,851 (5 ) 610 (2 ) 4,461 (7 ) Mortgage-backed securities — — — — — — $ 3,851 $ (5 ) $ 610 $ (2 ) $ 4,461 $ (7 ) 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 March 31, 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 March 31, 2016 and December 31, 2015.

Interest income recognized on total impaired loans for the three months ended March 31, 2016 and for the year ended December 31, 2015 amounted to approximately $0.1 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 $0.4 million and $1.7 million for the three months ended March 31, 2016 and for the year ended December 31, 2015, respectively. Troubled Debt Restructurings The Company has allocated approximately $0.3 million and $0.7 million of specific reserves to customers whose loan terms have been modified in troubled debt restructurings (“TDR”) at March 31, 2016 and December 31, 2015, respectively. The Company has no additional lending commitments at March 31, 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 March 31, 2016, and December 31, 2015. The following table presents the TDRs by loan class at March 31, 2016 and December 31, 2015: Non-Accrual Restructured and Accruing Total (dollars in thousands) March 31, 2016 Agricultural loans $ 6,165 $ — $ 6,165 Commercial real estate loans 504 483 987 Commercial loans 107 119 226 Residential real estate loans — — — Installment and consumer other — — — Total $ 6,776 $ 602 $ 7,378 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 less of an 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 March 31, 2016 and December 31, 2015: As of March 31, 2016 Sound/ Acceptable/ Satisfactory/ Low Satisfactory Watch Special Mention Substandard Total Loans (dollars in thousands) Agricultural loans $ 463,869 $ 27,903 $ 13,085 $ 15,899 $ 520,756 Commercial real estate loans 141,961 15,030 4,399 4,173 165,563 Commercial loans 42,409 5,218 512 4,379 52,518 Residential real estate loans 29,626 4,561 2,529 107 36,823 Installment and consumer other 186 2 — — 188 Total $ 678,051 $ 52,714 $ 20,525 $ 24,558 $ 775,848 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 $505.5 million and $495.9 million at March 31, 2016 and December 31, 2015, respectively. The fair value of these rights were approximately $10.9 million and $10.7 million at March 31, 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: March 31, December 31, 2016 2015 (dollars in thousands) Loan servicing rights: Balance, beginning of period $ 8,145 $ 7,746 Additions 1,023 3,731 Disposals (378 ) (1,421 ) Amortization (496 ) (1,911 ) Balance, end of period $ 8,294 $ 8,145

Disclosure Of Compensation Related Costs Sharebased Payments [Abstract]
EQUITY INCENTIVE PLAN	NOTE 8 – EQUITY INCENTIVE PLAN Under the Company’s 2012 Equity Incentive Compensation Plan (the “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 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 Plan and changes in the Plan as of March 31, 2016 are as follows: March 31, 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 18,675 19.77 Exercised (1,943 ) 17.15 Forfeited/expired — — Outstanding, end of period 368,663 $ 14.00 $ 2,241 Options exercisable at period-end 265,033 $ 12.46 $ 2,020 Weighted-average fair value of options granted during the period (2) $ 4.84 (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 March 31, 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 March 31, 2016 is as follows: March 31, 2016 RSAs Weighted Average Grant Price Outstanding, beginning of year 46,621 $ 14.92 Granted 13,757 19.77 Vested (10,980 ) 12.00 Forfeited/expired — — Outstanding, end of period 49,398 $ 16.92 For the three months ended March 31, 2016 and 2015, share-based compensation expense, including options and restricted stock awards, applicable to the Plan was $128.0 thousand and $53.0 thousand, respectively. As of March 31, 2016, unrecognized share-based compensation expense related to nonvested options and restricted stock awards amounted to $1.0 million and is expected to be recognized over a weighted average period of 2.0 years.

Regulatory Capital Requirements [Abstract]
REGULATORY MATTERS	NOTE 9 – REGULATORY MATTERS The Company (on a consolidated basis) and Investors Community Bank (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 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 and Tier 1 capital to risk-weighted assets, and of Tier 1 capital to average assets, as such terms are defined in the regulations. Management believed, as of March 31, 2016 and December 31, 2015, that the Company and the Bank met all capital adequacy requirements to which they were subject. As of March 31, 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, 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: Minimum To Be Well Capitalized Under Prompt Corrective Action Provisions: Amount Ratio Amount Ratio Amount Ratio (dollars in thousands) March 31, 2016 Total Capital (to risk weighted assets): Consolidated $ 131,691 15.59 % $ 67,567 8.00 % No t Bank 114,237 13.53 % 67,551 8.00 % $ 84,438 10.00 % Tier 1 Capital (to risk weighted assets): Consolidated 121,121 14.34 % 50,675 6.00 % Not applicable Bank 103,667 12.28 % 50,663 6.00 % 67,551 8.00 % Tier 1 Capital (to average assets): Consolidated 121,121 13.44 % 36,047 4.00 % Not applicable Bank 103,667 11.51 % 36,026 4.00 % 45,033 5.00 % Tier 1 Common Equity Ratio (to risk weighted assets): Consolidated 100,749 11.93 % 43,285 5.13 % Not applicable Bank 103,667 12.28 % 43,275 5.13 % 54,885 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 % 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 MEASUREMENTS

FAIR VALUE MEASUREMENTS	3 Months Ended

Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS	NOTE 10 – 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 are 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 ninety days approximate their fair values. Advances from FHLB Current market rates for debt with similar terms and remaining maturities are used to estimate fair value of existing debt. Fair values are estimated using discounted cash flow analyses based on current market rates for similar types of borrowing arrangements. Subordinated Debentures The carrying amounts approximate fair value. Accrued Interest The carrying amounts approximate fair value. Commitments to Extend Credit and Standby Letters of Credit As of March 31, 2016 and December 31, 2015, the carrying and fair values of the commitment to extend credit and standby letters of credit are not considered significant.
