Organization, Consolidation and Presentation of Financial Statements [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Centrue Financial Corporation is a bank holding company organized under the laws of the State of Delaware. When we use the terms “Centrue,” the “Company,” “we,” “us,” and “our,” we mean Centrue Financial Corporation, a Delaware Corporation, and its consolidated subsidiary. When we use the term the “Bank,” we are referring to our wholly owned banking subsidiary, Centrue Bank. The Company and the Bank provide a full range of banking services to individual and corporate customers located in markets extending from the far western and southern suburbs of the Chicago metropolitan area across Central Illinois down to the metropolitan St. Louis area. These services include demand, time, and savings deposits; business and consumer lending; and mortgage banking. The Company is subject to competition from other financial institutions and nonfinancial institutions providing financial services. Additionally, the Company and the Bank are subject to regulations of certain regulatory agencies and undergo periodic examinations by those regulatory agencies. Basis of presentation The accounting and reporting policies of the Company and its subsidiaries conform to U.S. generally accepted accounting principles (“GAAP”) and general practice within the banking industry. The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates. Material estimates which are particularly susceptible to significant change in the near term relate to the fair value of investment securities and other-than-temporary impairment of securities, the determination of the allowance for loan losses and valuation of other real estate owned. For further information with respect to significant accounting policies followed by the Company in the preparation of its consolidated financial statements, refer to the Company’s registration statement filed with the SEC on October 15, 2015 which includes the audited financial statements and notes for the year ended December 31, 2014 . The consolidated financial statements include the accounts of the Company and Centrue Bank. Intercompany balances and transactions have been eliminated in consolidation and certain 2014 amounts have been reclassified to conform to the 2015 presentation. The annualized results of operations during the three and nine months ended September 30, 2015 are not necessarily indicative of the results expected for the year ending December 31, 2015 . All financial information in the following tables is in thousands (000s), except share and per share data. In the opinion of management, all normal and recurring adjustments which are necessary to fairly present the results for the interim periods presented have been included. Reverse Stock Split Common shares and per share amounts for all periods shown have been restated to reflect the impact of the 1: 30 reverse stock split the Company completed effective May 29, 2015. Capital Event On March 31, 2015, the Company completed the issuance of $76.0 million of new common stock in a private placement offering. A total of 6.3 million shares were sold in the offering at a price of $12.00 per share. In conjunction with the stock offering the Company used the proceeds in part to pay $4.9 million in accrued but unpaid interest on its subordinated debentures, redeemed all $32.7 million of Series C Preferred Stock for $19.0 million , settled $10.3 million in notes payable with MB Financial for $8.5 million and made a $36.0 million capital contribution into Centrue Bank. The remaining proceeds have been and will be used for general corporate purposes. Recent Accounting Pronouncements In April 2015, the FASB issued an update, ASU No. 2015-05, Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement. ASU 2015-05 provides guidance to customers about whether a cloud computing arrangement includes a software license. If a cloud computing arrangement includes a software license, the customer should account for the software license element of the arrangement consistent with the acquisition of other software licenses. If the arrangement does not include a software license, the customer should account for a cloud computing arrangement as a service contract. This amendment is effective for fiscal years beginning after December 15, 2015, and interim periods beginning after December 15, 2016. Early adoption is permitted. The amendment may be adopted either prospectively to all arrangements entered into or materially modified after the effective date or retrospectively. The Company intends to adopt the accounting standard during 2016, as required, with no material impact. In June of 2014, the FASB issued an update, ASU No. 2014-11 Transfers and Servicing (Topic 860), guidance that requires repurchase-to-maturity transactions to be accounted for as secured borrowings and with additional disclosures. The guidance also requires separate accounting for a transfer of a financial asset executed contemporaneously with a repurchase agreement with the same counterparty. If the derecognition criteria are met as outlined in the guidance, the initial transfer will generally be accounted for as a sale and the repurchase agreement will generally be accounted for as a secured borrowing. The guidance is effective for annual reporting periods beginning after December 15, 2014 and interim reporting periods after December 15, 2015. Management is evaluating the new guidance, but does not expect the adoption of this guidance will materially impact the Company's financial condition, results of operations, or liquidity. In May 2014, the FASB issued an update (ASU No. 2014-09, Revenue from Contracts with Customers) creating FASB Topic 606, Revenue from Contracts with Customers. The guidance in this update affects any entity that either enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of nonfinancial assets unless those contracts are within the scope of other standards (for example, insurance contracts or lease contracts). The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The guidance provides steps to follow to achieve the core principle. An entity should disclose sufficient information to enable users of financial statements to understand the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. Qualitative and quantitative information is required about contracts with customers, significant judgments and changes in judgments, and assets recognized from the costs to obtain or fulfill a contract. The amendments in this update will become effective for annual periods and interim periods within those annual periods beginning after December 15, 2016. We are currently evaluating the impact of adopting the new guidance on the consolidated financial statements.

Earnings Per Share [Abstract]
Earnings Per Share	Earnings Per Share A reconciliation of the numerators and denominators for earnings per common share computations for the three and nine months ended September 30, 2015 and 2014 is presented below (shares in thousands). Common shares, options, and per share amounts for all periods shown have been restated to reflect the impact of the thirty for one stock split the Company completed effective May 29, 2015. Options to purchase 3,488 and 6,083 shares of common stock were outstanding for September 30, 2015 and 2014 , respectively; but were not included in the computation of diluted earnings per share because the exercise price was greater than the average market price and, therefore, were anti-dilutive.

Loans	Loans The major classifications of loans follow: Aggregate Principal Amount September 30, 2015 December 31, 2014 Commercial $ 66,110 61,561 Agricultural & AG RE 46,323 53,193 Construction, land & development 24,844 13,860 Commercial RE 372,654 315,213 1-4 family mortgages 98,732 106,472 Consumer 3,255 2,901 Total Loans $ 611,918 553,200 Allowance for loan losses (8,403 ) (7,981 ) Loans, net $ 603,515 545,219 The credit quality indicator utilized by the Company to internally analyze the loan portfolio is the internal risk rating. Internal risk ratings of 0 to 5 are considered pass credits, a risk rating of a 6 is special mention, a risk rating of a 7 is substandard, and a risk rating of an 8 is doubtful. Loans classified as pass credits have no material weaknesses and are performing as agreed. Loans classified as special mention have a potential weakness that deserves management's close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or of the institution's credit position at some future date. Loans classified as substandard are inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. Loans so classified have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the institution will sustain some loss if the deficiencies are not corrected. Loans 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 and improbable.

Specific reserves were immaterial at September 30, 2015 and December 31, 2014 . At September 30, 2015 nonaccrual TDR loans were $0.13 million and $0.02 million at December 31, 2014 . There were $0.03 million TDRs on accrual at September 30, 2015 compared to none at December 31, 2014 . The Company had no commitments to lend additional amounts to a customer with an outstanding loan that is classified as TDR as of September 30, 2015 and December 31, 2014 . During the nine month period ended September 30, 2015 , the terms of a certain loans were modified as troubled debt restructurings. The modification of the terms of such loans may include one or a combination of the following: a reduction of the stated interest rate of the loan to a below market rate or the payment modification to interest only. A modification involving a reduction of the stated interest rate of the loan would be for periods ranging from 6 months to 16 months . During the nine month period ended September 30, 2015 , there were two TDR added in a total amount of $0.1 million compared to the year ended December 31, 2014 in which two loans were added as TDRs in the amount of $5.0 million . The $5.0 million of TDRs added in 2014 were subsequently sold in the fourth quarter of 2014 . During the three months ending September 30, 2015 there was one 1-4 family residential loan modified as a troubled debt restructuring with a recorded investment of $0.1 million ; compared to the same three month period ended September 30, 2014 when there were no loans modified as troubled debt restructurings. The following tables present loans by class modified as troubled debt restructurings that occurred during the nine months ending September 30, 2015 and 2014 : For the Nine Months Ended September 30, 2015 Number of Loans Pre-Modification Recorded Investment Post-Modification Recorded Investment 1-4 family residential Senior lien 2 127 127 Total 2 $ 127 $ 127 The troubled debt restructurings described above did not have a material impact to the allowance for loan losses and did not result in any additional charge-offs during the nine months ending September 30, 2015 . For the Nine Months Ended September 30, 2014 Number of Loans Pre-Modification Recorded Investment Post-Modification Recorded Investment Construction, land & development 1 $ 5,013 $ 5,013 1-4 family residential Jr. lien & lines of credit 1 34 34 Total 2 $ 5,047 $ 5,047 The troubled debt restructurings described above did not have a material impact to the allowance for loan losses and did not result in any additional charge-offs during the nine months ending September 30, 2014 . A loan is considered to be in payment default once it is 90 days contractually past due under the modified terms. In the nine months ending September 30, 2015 and the nine months ending September 30, 2014 there were no loans modified as troubled debt restructurings for which there was a payment default within twelve months following the modification. The Company evaluates loan modifications to determine if the modification constitutes a troubled debt restructure. A loan modification constitutes a troubled debt restructure if the borrower is experiencing financial difficulty and the Company grants a concession it would not otherwise consider. In order to determine whether a borrower is experiencing financial difficulty, an evaluation is performed of the probability that the borrower will be in payment default on any of its loans with the Company’s debt in the foreseeable future without the modification. This evaluation is performed under the Company’s internal underwriting guidelines. TDRs are separately identified for impairment disclosures. If a loan is considered to be collateral dependent loan, the TDR is reported, net, at the fair value of the collateral.

Fair Value Disclosures [Abstract]
Fair Value	Fair Value The Company measures, monitors, and discloses certain of its assets and liabilities on a fair value basis. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The Company maximizes the use of observable inputs and minimizes the use of unobservable inputs when measuring fair value. Fair value guidance establishes a fair value hierarchy that prioritizes the inputs used to measure fair value into three broad levels based on the reliability of the input assumptions. The hierarchy gives the highest priority to level 1 measurements and the lowest priority to level 3 measurements and the categorization of where an asset or liability falls within the hierarchy is based on the lowest level of input that is significant to the fair value measurement. The three levels of the fair value hierarchy are defined as follows: Level 1 - Unadjusted quoted prices for identical assets or liabilities traded in active markets. Level 2 - Observable inputs other than level 1 prices, such as quoted prices for similar instruments; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the asset or liability. Level 3 - Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. The Company used the following methods and significant assumptions to estimate the fair value of each type of financial instrument: Securities Available for Sale Securities. The fair value of securities available for sale is determined by obtaining quoted prices on nationally recognized securities exchanges (Level 1 inputs) or matrix pricing, which is a mathematical technique widely used in the industry to value debt securities without relying exclusively on quoted prices for the specific securities but rather by relying on the securities’ relationship to other benchmark quoted securities (Level 2 inputs). If the securities could not be priced using quoted market prices, observable market activity or comparable trades, the financial market was considered not active and the assets were classified as Level 3. Single Issue Trust Preferred. In 2010 the Company purchased single-issue trust preferred securities that are classified as available for sale. With respect to these securities, the Company looks at rating agency actions, payment history, the capital levels of the banks and the financial performance as filed in regulatory reports. At December 31, 2014 , the Company still held $0.8 million of these securities. During 2015 , the last of the Company’s single-issue trust preferred securities were called and at September 30, 2015 none were held in the securities portfolio. Assets and Liabilities Measured at Fair Value on a Recurring Basis The following table summarizes, by measurement hierarchy, the various assets and liabilities of the Company that are measured at fair value on a recurring basis: Carrying Amount Quoted Prices in Active Markets For Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) September 30, 2015 U.S. government agencies $ 40,924 $ — $ 40,924 $ — State and political subdivisions 14,890 — 14,890 — U.S. government agency residential mortgage-backed securities 128,964 — 128,964 — Collateralized mortgage obligations: Agency 18,876 — 18,876 — Equities 2,776 — 2,776 — Available-for-sale securities $ 206,430 $ — $ 206,430 $ — Carrying Amount Quoted Prices in Active Markets For Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) December 31, 2014 U.S. government agencies $ 21,109 $ — $ 21,109 $ — State and political subdivisions 9,028 — 9,028 — U.S. government agency residential mortgage-backed securities 99,668 — 99,668 — Collateralized mortgage obligations: Agency 38 — 38 — Equities 2,736 — 2,736 — Collateralized debt obligations: Single Issue 762 — 762 — Corporate 2,030 — 2,030 — Available-for-sale securities $ 135,371 $ — $ 135,371 $ — There were no transfers between Level 1 and Level 2 during the first nine months of 2015 and all of 2014 .

Impaired loans carried at fair value generally receive specific allocations of the allowance for loan losses. For collateral dependent loans, fair value is commonly based on recent real estate appraisals. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach. Adjustments are routinely made in the appraisal process by the independent appraisers to adjust for differences between the comparable sales and income data available. Such adjustments are usually significant and typically result in a Level 3 classification of the inputs for determining fair value. Non-real estate collateral may be valued using an appraisal, net book value per the borrower’s financial statements, or aging reports, adjusted or discounted based on management’s historical knowledge, changes in market conditions from the time of the valuation, and management’s expertise and knowledge of the client and client’s business, resulting in a Level 3 fair value classification. Impaired loans are evaluated on a quarterly basis for additional impairment and adjusted accordingly. Impaired loans had a carrying amount of $0.2 million at September 30, 2015 , with no specific loan loss allocation and no effect on the provision for loan losses for the nine month period. In 2014 impaired loans had a carrying amount of $0.9 million with a specific loan loss allocation of $0.5 million during 2014 , resulting in an additional provision for loan losses of $0.5 million for the year ended December 31, 2014 . The majority of the Bank's impaired loans are collateralized by real estate. Assets acquired through or instead of loan foreclosure are initially recorded at fair value less costs to sell when acquired, establishing a new cost basis. Any write-downs in the carrying value of a property at the time of acquisition are charged against the allowance for loan losses. These assets are subsequently accounted for at lower of cost or fair value less estimated costs to sell. Management periodically reviews the carrying value of other real estate owned. Any write-downs of the properties subsequent to acquisition, as well as gains or losses on disposition and income or expense from the operations of other real estate owned, are recognized in operating results in the period they are realized. Fair value is commonly based on recent real estate appraisals. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach. Adjustments are routinely made in the appraisal process by the independent appraisers to adjust for differences between the comparable sales and income data available. Such adjustments are usually significant and typically result in a Level 3 classification of the inputs for determining fair value. OREO properties measured at fair value, less costs to sell, had a net carrying amount of $5.7 million which is made up of the outstanding balance of $7.5 million , net of a valuation allowance of $1.8 million at September 30, 2015 . This compares to 2014 when OREO properties with an outstanding balance of $6.0 million was written down to a fair value of $4.5 million .

In addition, nonfinancial instruments typically not recognized in financial statements nevertheless may have value but are not included in the above disclosures. These include, among other items, the estimated earning potential of core deposit accounts, the earnings potential of loan servicing rights, the earnings potential of the trust operations, customer goodwill and similar items. The methods and assumptions, not previously presented, used to estimate fair values are described as follows: (a) Cash and Cash Equivalents The carrying amounts of cash and short-term instruments approximate fair values and are classified as either Level 1 or Level 2. As of September 30, 2015 and December 31, 2014 ; $45.7 million and $44.2 million was classified as Level 1. (b) Restricted securities It is not practical to determine the fair value of restricted securities due to the restrictions placed on its transferability. (c) Loans Fair values of loans, excluding loans held for sale, are estimated as follows: Fair values for 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 resulting in a Level 3 classification. Impaired loans are valued at the lower of cost or fair value as described previously. The methods utilized to estimate the fair value of loans do not necessarily represent an exit price. The fair value of loans held for sale is estimated based upon binding contracts and quotes from third party investors resulting in a Level 2 classification. (d) Deposits The fair values disclosed for demand deposits (e.g., interest and non-interest checking, passbook 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 amount) resulting in a Level 2. Fair values for fixed rate certificates of deposit are estimated using a discounted cash flows calculation that applies interest rates currently being offered on certificates to a schedule of aggregated expected monthly maturities on time deposits resulting in a Level 2 classification. (e) Short-term Borrowings The carrying amounts of federal funds purchased, borrowings under repurchase agreements, and other short-term borrowings, generally maturing within ninety days, approximate their fair values resulting in a Level 2 classification. (f) Other Borrowings The fair values of the Company’s long-term borrowings are estimated using discounted cash flow analyses based on the current borrowing rates for similar types of borrowing arrangements resulting in a Level 2 classification. The fair values of the Company’s Subordinated Debentures are estimated using discounted cash flow analyses based on the current borrowing rates for similar types of borrowing arrangements resulting in a Level 3 classification. (g) Accrued Interest Receivable/Payable The carrying amounts of accrued interest approximate fair value resulting in a Level 2 or Level 3 classification which is consistent with the underlying asset/liability they are associated with. (h) Off-balance Sheet Instruments Fair values for off-balance sheet, credit-related financial instruments are based on fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and the counterparties’ credit standing. The fair value of commitments is not material.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes In accordance with current income tax accounting guidance, the Company assessed whether a valuation allowance should be established against their deferred tax assets (DTAs) based on consideration of all available evidence using a “more likely than not” standard. The most significant portions of the deductible temporary differences relate to (1) net operating loss carryforwards and (2) the allowance for loan losses. In assessing the need for a valuation allowance, both the positive and negative evidence about the realization of DTAs were evaluated. The ultimate realization of DTAs is based on the Company’s ability to carryback net operating losses to prior tax periods, tax planning strategies that are prudent and feasible, the reversal of deductible temporary differences that can be offset by taxable temporary differences and future taxable income. After evaluating all of the factors previously summarized and considering the weight of the positive evidence compared to the negative evidence, the Company has determined a full valuation adjustment was necessary as of September 30, 2015 and December 31, 2014 . Below is a summary of items included in the deferred tax inventory as of September 30, 2015 and December 31, 2014 : September 30, 2015 December 31, 2014 Deferred tax assets Allowance for loan losses $ 3,268 $ 3,107 Deferred compensation, other 77 104 Stock based expense 130 130 Net operating loss carryforwards 35,204 36,955 Deferred tax credits 696 697 OREO valuation allowance 1,102 1,080 Donation carryforward 232 232 Capital loss carryforward — 4 Other 45 45 Total deferred tax assets 40,754 42,354 Deferred tax liabilities Depreciation $ (50 ) $ (41 ) Adjustments arising from acquisitions (227 ) (502 ) Mortgage servicing rights (844 ) (872 ) Securities available-for-sale (101 ) (166 ) Federal Home Loan Bank dividend received in stock (450 ) (451 ) Deferred loan fees & costs (397 ) (373 ) Prepaid expenses (190 ) (190 ) Total deferred tax liabilities (2,259 ) (2,595 ) Valuation allowance (38,495 ) (39,759 ) Net deferred tax assets $ — $ —

Share Based Compensation	Share Based Compensation In April 2003, the Company adopted the 2003 Option Plan. Under the 2003 Option Plan, as amended on April 24, 2007, nonqualified options, incentive stock options, restricted stock and/or stock appreciation rights may be granted to employees and outside directors of the Company and its subsidiaries to purchase the Company's common stock at an exercise price to be determined by the executive and compensation committee. Pursuant to the 2003 Option Plan, 19,000 shares of the Company's unissued common stock had been reserved and were available for issuance upon the exercise of options and rights granted under the 2003 Option Plan. The granted options have an exercise period of seven to ten years from the date of grant. In May 2015, the Company adopted the 2015 Stock Compensation Plan. Under the 2015 Stock Compensation Plan nonqualified options, incentive stock options, restricted stock and/or stock appreciation rights may be granted to employees and outside directors of the Company and its subsidiaries to purchase the Company's common stock at an exercise price to be determined by the compensation committee. A total of 430,000 shares have been made available under this plan. No options or restricted stock were granted or exercised for the nine months ended September 30, 2015 and none were granted or exercised for the year ended December 31, 2014 . There was no compensation cost charged against income for the stock options portion of the equity incentive plans for the nine months ended September 30, 2015 and for the year ended December 31, 2014 . The fair value of each option award is estimated on the date of grant using a closed form option valuation (Black-Scholes) model that uses the assumptions noted in the table below. Expected volatilities are based on historical volatilities of the Company’s common stock prior to its deregistration. The Company uses historical data to estimate option exercise and post-vesting termination behavior. (Employee and management options are tracked separately.) The expected term of options granted is based on historical data and represents the period of time that options granted are expected to be outstanding, which takes into account that the options are not transferable. The risk-free interest rate for the expected term of the option is based on the U.S. Treasury yield curve in effect at the time of the grant. There were no options granted for the nine months ended September 30, 2015 and the year ended December 31, 2014 . A status summary of the option plan as of September 30, 2015 and changes during the period ended on that date are presented below: Shares Weighted-Average Exercise Price Weighted-Average Remaining Contractual Life Aggregate Intrinsic Value Outstanding at January 1, 2015 6,063 $ 447.19 Granted — — Exercised — — Forfeited (2,575 ) 556.00 Outstanding at end of period 3,488 $ 366.87 0.6 years $ — Vested or expected to vest 3,488 $ 366.87 0.6 years $ — Options exercisable at period end 3,488 $ 366.87 0.6 years $ — Options outstanding at September 30, 2015 and year-end 2014 were as follows: Outstanding Exercisable Range of Exercise Prices Number Weighted Average Remaining Contractual Life Number Weighted Average Exercise Price September 30, 2015 $157.20 - $390.00 2,160 0.4 years 2,160 $ 228.33 416.40 - 558.90 — 0.0 years — — 570.90 - 699.30 1,328 0.9 years 1,328 592.20 3,488 0.6 years 3,488 $ 366.87 December 31, 2014: $157.20 - $390.00 2,160 1.2 years 2,160 $ 228.33 416.40 - 558.90 2,077 0.2 years 2,077 543.29 570.90 - 699.30 1,826 1.6 years 1,826 596.78 6,063 1.0 year 6,063 $ 447.19 As of September 30, 2015 and December 31, 2014 , there was no unrecognized compensation cost related to non-vested stock options granted under the 2003 Option Plan.

Regulatory Matters

Banking and Thrift [Abstract]
Regulatory Matters	Regulatory Matters The Company and Centrue Bank are subject to regulatory capital requirements administered by federal and state banking agencies that involve the quantitative measure of their assets, liabilities, and certain off-balance-sheet items, as calculated under regulatory accounting practices. Quantitative measures established by regulations to ensure capital adequacy require the Company and Centrue Bank to maintain minimum amounts and ratios (set forth in the table below) of total, Tier 1 capital and Common Equity Tier 1 capital (as defined in the regulations) to risk-weighted assets (as defined in the regulations), and, for the Bank, Tier 1 capital (as defined in the regulations) to average assets (as defined in the regulations). Failure to meet minimum capital requirements may cause regulatory bodies to initiate certain discretionary and/or mandatory actions that, if undertaken, may have a direct material effect on our financial statements. The Company, as a financial holding company, is required to be “adequately capitalized” in the capital categories shown in the table below. As of September 30, 2015 , the Company is "adequately capitalized." As of September 30, 2015 , Centrue Bank met all capital adequacy requirements to which they were subject, including the guidelines to be considered “well capitalized.” On July 2, 2013, the Federal Reserve Board and the FDIC approved rules that implement the “Basel III” regulatory capital reforms, as well as certain changes required by the Dodd-Frank Act. The rules include a common equity Tier 1 capital conservation buffer of 2.5% of risk-weighted assets, which is in addition to the Tier 1 and Tier 2 risk-based capital requirements. The capital conservation buffer will be phased in over four years beginning on January 1, 2016, with a maximum buffer of 0.625% of risk-weighted assets for 2016, 1.25% for 2017, 1.875% for 2018, and 2.5% for 2019 and thereafter. Failure to maintain the required capital conservation buffer will result in limitations on capital distributions and on discretionary bonuses to executive officers.

The Agreement is based on the findings of the Federal Reserve-Chicago and the IDFPR during an examination that commenced in June 2009 (the “Examination”). Since the completion of the Examination, the boards of directors of the Company and the Bank have aggressively taken steps to address the findings of the Examination. The Company and the Bank have taken an active role in working with the Federal Reserve Board and the IDFPR to improve the condition of the Bank and have addressed the items included in the Agreement. Under the terms of the Agreement, the Bank must prepare and submit written plans and/or reports to the regulators that address the following items: strengthening the Bank’s credit risk management practices; improving loan underwriting and loan administration; improving asset quality by enhancing the Bank’s position on problem loans through repayment, additional collateral or other means; reviewing and revising as necessary the Bank’s allowance for loan and lease losses policy; maintaining sufficient capital at the Bank; implementing an earnings plan and comprehensive budget to improve and sustain the Bank’s earnings; and improving the Bank’s liquidity position and funds management practices. While the Agreement remains in place, the Company and the Bank may not pay dividends and the Company may not increase debt or redeem any shares of its stock without the prior written consent of the regulators. Further, the Bank will comply with applicable laws and regulations. The Company and the Bank are in compliance with all the requirements specified in the Agreement. The Company and the Bank believe that the proactive steps that have been taken by the board of directors and by management will help the Company and the Bank address the Agreement and the concerns leading to the Agreement.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of presentation	Basis of presentation The accounting and reporting policies of the Company and its subsidiaries conform to U.S. generally accepted accounting principles (“GAAP”) and general practice within the banking industry. The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates. Material estimates which are particularly susceptible to significant change in the near term relate to the fair value of investment securities and other-than-temporary impairment of securities, the determination of the allowance for loan losses and valuation of other real estate owned. For further information with respect to significant accounting policies followed by the Company in the preparation of its consolidated financial statements, refer to the Company’s registration statement filed with the SEC on October 15, 2015 which includes the audited financial statements and notes for the year ended December 31, 2014 . The consolidated financial statements include the accounts of the Company and Centrue Bank. Intercompany balances and transactions have been eliminated in consolidation and certain 2014 amounts have been reclassified to conform to the 2015 presentation. The annualized results of operations during the three and nine months ended September 30, 2015 are not necessarily indicative of the results expected for the year ending December 31, 2015 . All financial information in the following tables is in thousands (000s), except share and per share data. In the opinion of management, all normal and recurring adjustments which are necessary to fairly present the results for the interim periods presented have been included.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In April 2015, the FASB issued an update, ASU No. 2015-05, Customer’s Accounting for Fees Paid in a Cloud Computing Arrangement. ASU 2015-05 provides guidance to customers about whether a cloud computing arrangement includes a software license. If a cloud computing arrangement includes a software license, the customer should account for the software license element of the arrangement consistent with the acquisition of other software licenses. If the arrangement does not include a software license, the customer should account for a cloud computing arrangement as a service contract. This amendment is effective for fiscal years beginning after December 15, 2015, and interim periods beginning after December 15, 2016. Early adoption is permitted. The amendment may be adopted either prospectively to all arrangements entered into or materially modified after the effective date or retrospectively. The Company intends to adopt the accounting standard during 2016, as required, with no material impact. In June of 2014, the FASB issued an update, ASU No. 2014-11 Transfers and Servicing (Topic 860), guidance that requires repurchase-to-maturity transactions to be accounted for as secured borrowings and with additional disclosures. The guidance also requires separate accounting for a transfer of a financial asset executed contemporaneously with a repurchase agreement with the same counterparty. If the derecognition criteria are met as outlined in the guidance, the initial transfer will generally be accounted for as a sale and the repurchase agreement will generally be accounted for as a secured borrowing. The guidance is effective for annual reporting periods beginning after December 15, 2014 and interim reporting periods after December 15, 2015. Management is evaluating the new guidance, but does not expect the adoption of this guidance will materially impact the Company's financial condition, results of operations, or liquidity. In May 2014, the FASB issued an update (ASU No. 2014-09, Revenue from Contracts with Customers) creating FASB Topic 606, Revenue from Contracts with Customers. The guidance in this update affects any entity that either enters into contracts with customers to transfer goods or services or enters into contracts for the transfer of nonfinancial assets unless those contracts are within the scope of other standards (for example, insurance contracts or lease contracts). The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The guidance provides steps to follow to achieve the core principle. An entity should disclose sufficient information to enable users of financial statements to understand the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. Qualitative and quantitative information is required about contracts with customers, significant judgments and changes in judgments, and assets recognized from the costs to obtain or fulfill a contract. The amendments in this update will become effective for annual periods and interim periods within those annual periods beginning after December 15, 2016. We are currently evaluating the impact of adopting the new guidance on the consolidated financial statements.
