Summary of Significant Accounting Policies	Basis of Presentation : BankFinancial Corporation, a Maryland corporation headquartered in Burr Ridge, Illinois, is the owner of all of the issued and outstanding capital stock of BankFinancial, F.S.B. (the “Bank”). The interim unaudited consolidated financial statements include the accounts of and transactions of BankFinancial Corporation, the Bank, and the Bank’s wholly-owned subsidiaries, Financial Assurance Services, Inc. and BF Asset Recovery Corporation (collectively, “the Company”), and reflect all normal and recurring adjustments that are, in the opinion of management, considered necessary for a fair presentation of the financial condition and results of operations for the periods presented. All significant intercompany accounts and transactions have been eliminated. The results of operations for the three- month period ended March 31, 2016 are not necessarily indicative of the results of operations that may be expected for the year ending December 31, 2016. Certain information and note disclosures normally included in financial statements prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”) have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission. Use of Estimates : To prepare financial statements in conformity with GAAP, management makes estimates and assumptions based on available information. These estimates and assumptions affect the amounts reported in the financial statements and the disclosures provided, and future results could differ. Reclassifications : Certain reclassifications have been made in the prior period’s financial statements to conform them to the current period’s presentation. These unaudited consolidated financial statements should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2015 , as filed with the Securities and Exchange Commission.

All securities reflected in the preceding table were classified as available-for-sale at March 31, 2016 and December 31, 2015 . The amortized cost and fair values of securities by contractual maturity are shown below. Securities not due at a single maturity date are shown separately. Expected maturities may differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without call or prepayment penalties.

Certain residential mortgage-backed securities and certain collateralized mortgage obligations that the Company holds in its investment portfolio were in an unrealized loss position at March 31, 2016 , but the unrealized losses were not considered significant under the Company’s impairment testing methodology. In addition, the Company does not intend to sell these securities, and it is likely that the Company will not be required to sell these securities before their anticipated recovery occurs.

Some loans may be included in both categories, and some may only be included in one category. Nonaccrual loans include both smaller balance homogeneous loans that are collectively evaluated for impairment and individually classified impaired loans. The Company’s reserve for uncollected loan interest was $221,000 and $181,000 at March 31, 2016 and December 31, 2015 , respectively. When a loan is on non-accrual status and the ultimate collectability of the total principal of an impaired loan is in doubt, all payments are applied to principal under the cost recovery method. Alternatively, when a loan is on non-accrual status but there is doubt concerning only the ultimate collectability of interest, contractual interest is credited to interest income only when received, under the cash basis method pursuant to the provisions of FASB ASC 310–10, as applicable. In all cases, the average balances are calculated based on the month–end balances of the financing receivables within the period reported pursuant to the provisions of FASB ASC 310–10, as applicable.

In general, if the Company grants a loan extension or modification to a borrower for other than an insignificant period of time that includes a below–market interest rate, principal forgiveness, payment forbearance or other concession intended to minimize the economic loss to the Company, the loan extension or loan modification is classified as a TDR. In cases where borrowers are granted new terms that provide for a reduction of either interest or principal then due and payable, management measures any impairment on the restructured loan in the same manner as for impaired loans as noted above. The Company had $419,000 of TDRs at March 31, 2016 compared to $2.7 million at December 31, 2015 , with no specific valuation reserves allocated to those loans at March 31, 2016 and December 31, 2015 . The Company had no outstanding commitments to borrowers whose loans were classified as TDRs at either date. During the first quarter of 2016, six loans totaling $1.5 million were declassified as TDRs as they successfully met the regulatory criteria to be removed from TDR status. The following table presents loans classified as TDRs: March 31, 2016 December 31, 2015 One-to-four family residential real estate $ 248 $ 1,385 Multi-family mortgage — 1,119 Troubled debt restructured loans – accrual loans 248 2,504 One-to-four family residential real estate 171 174 Troubled debt restructured loans – nonaccrual loans 171 174 Total troubled debt restructured loans $ 419 $ 2,678 During the three months ending March 31, 2016 and 2015 , the terms of certain loans were modified and classified as TDRs. The modification of the terms of such loans included one or a combination of the following: a reduction of the stated interest rate of the loan; an extension of the maturity date at a stated rate of interest lower than the current market rate for new debt with similar risk; or a permanent reduction of the recorded investment in the loan. The following tables present TDR activity: Three Months Ended March 31, 2016 2015 Number of loans Pre- Modification outstanding recorded investment Post- Modification outstanding recorded investment Number of loans Pre- Modification outstanding recorded investment Post- Modification outstanding recorded investment One-to-four family residential real estate 1 $ 63 $ 63 1 $ 63 $ 63 Due to reduction in interest rate Due to extension of maturity date Due to permanent reduction in recorded investment Total For the Three Months Ended March 31, 2016 One-to-four family residential real estate $ — $ 63 $ — $ 63 For the Three Months Ended March 31, 2015 One-to-four family residential real estate $ — $ 63 $ — $ 63 The TDRs described above had no impact on interest income, resulted in no change to the allowance for loan losses allocated and resulted in no charge-offs for the three months ended March 31, 2016 . The TDRs had no material impact on interest income, resulted in no change to the allowance for loan losses allocated and resulted in no charge-offs for the three months ended March 31, 2015 . The following table presents TDRs for which there was a payment default during the three months ending March 31, 2016 and 2015 within twelve months following the modification. 2016 2015 Number of loans Recorded investment Number of loans Recorded investment One-to-four family residential real estate 2 $ 42 2 $ 78 A loan is considered to be in payment default once it is 90 days contractually past due under the modified terms. The TDRs for which there was a payment default resulted in no change to the allowance for loan losses allocated and resulted in no charge-offs during the three months ending March 31, 2016 and 2015. There were no other loan modifications for the three months ending March 31, 2016 . There were certain other loan modifications during the three months ending March 31, 2015 that did not meet the definition of a TDR. These loans had a total recorded investment of $1.1 million at March 31, 2015 . The modification of these loans involved either a modification of the terms of a loan to borrowers who were not experiencing financial difficulties or a delay in a payment that was considered to be insignificant. 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 debt in the foreseeable future without the modification. This evaluation is performed under the Company’s internal underwriting policy. The Company categorizes loans into risk categories based on relevant information about the ability of borrowers to service their debt, including current financial information, historical payment experience, credit documentation, public information, and current economic trends, among other factors. The Company analyzes loans individually by classifying the loans based on credit risk. This analysis includes non-homogeneous loans, such as commercial and commercial real estate loans. This analysis is performed on a monthly basis. The Company uses the following definitions for risk ratings: Special Mention. A Special Mention asset has potential weaknesses that deserve management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the asset or in the institution’s credit position at some future date. Special Mention assets are not adversely classified and do not expose an institution to sufficient risk to warrant adverse classification. Substandard. Loans categorized as Substandard continue to accrue interest, but exhibit a well-defined weakness or weaknesses that may jeopardize the liquidation of the debt. The loans continue to accrue interest because they are well secured and collection of principal and interest is expected within a reasonable time. The risk rating guidance published by the Office of the Comptroller of the Currency clarifies that a loan with a well-defined weakness does not have to present a probability of default for the loan to be rated Substandard, and that an individual loan’s loss potential does not have to be distinct for the loan to be rated Substandard. Nonaccrual. An asset classified Nonaccrual has all the weaknesses inherent in one classified 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. The loans were placed on nonaccrual status. Loans not meeting the criteria above that are analyzed individually as part of the above described process are considered “Pass” rated loans. As of March 31, 2016 , based on the most recent analysis performed, the risk categories of loans by class of loans are as follows: Pass Special Mention Substandard Nonaccrual Total One-to-four family residential real estate loans $ 107,638 $ — $ 328 $ 3,178 $ 111,144 One-to-four family residential real estate loans – non-owner occupied 42,923 217 112 192 43,444 Multi-family mortgage loans - Illinois 311,205 339 2,838 956 315,338 Multi-family mortgage loans - Other 197,603 — 509 — 198,112 Nonresidential real estate loans 212,474 1,590 4,981 294 219,339 Construction loans 545 — — — 545 Land loans 427 — — 827 1,254 Commercial loans: Regional commercial banking 27,688 — 137 — 27,825 Health care 31,426 — — — 31,426 Direct commercial lessor 16,196 878 — — 17,074 Commercial leases: Investment rated commercial leases 182,057 — — — 182,057 Other commercial leases 90,530 262 — — 90,792 Consumer 1,890 — — — 1,890 $ 1,222,602 $ 3,286 $ 8,905 $ 5,447 $ 1,240,240 As of December 31, 2015 , based on the most recent analysis performed, the risk categories of loans by class of loans are as follows: Pass Special Mention Substandard Nonaccrual Total One-to-four family residential real estate loans $ 112,449 $ — $ 576 $ 1,936 $ 114,961 One-to-four family residential real estate loans – non-owner occupied 43,858 219 271 192 44,540 Multi-family mortgage loans - Illinois 312,329 344 4,656 828 318,157 Multi-family mortgage loans - Other 187,358 — 511 — 187,869 Nonresidential real estate loans 219,859 1,600 4,981 295 226,735 Construction loans 21 — — — 21 Land loans 450 — 842 — 1,292 Commercial loans: Regional commercial banking 29,377 — 614 — 29,991 Health care 31,809 — — — 31,809 Direct commercial lessor 17,716 — — — 17,716 Commercial leases: — Investment rated commercial leases 170,100 — — — 170,100 Other commercial leases 95,305 — — — 95,305 Consumer 1,831 — — — 1,831 $ 1,222,462 $ 2,163 $ 12,451 $ 3,251 $ 1,240,327

Fair Value Disclosures [Abstract]
Fair Value	Fair value is the exchange price that would be received for an asset or paid to transfer a liability (exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. There are three levels of inputs that may be used to measure fair values: • Level 1 – Quoted prices (unadjusted) for identical assets or liabilities in active markets that the entity has the ability to access as of the measurement date. • Level 2 – Significant other observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data. • Level 3 – Significant unobservable inputs that reflect a company’s own assumptions about the assumptions that market participants would use in pricing an asset or liability. The Company used the following methods and significant assumptions to estimate the fair value of each type of financial instrument: Securities : The fair values of marketable equity securities are generally determined by quoted prices, in active markets, for each specific security (Level 1). If Level 1 measurement inputs are not available for a marketable equity security, we determine its fair value based on the quoted price of a similar security traded in an active market (Level 2). The fair values of debt securities are generally determined by 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). Loans Held for Sale: Loans held for sale are carried at the lower of cost or fair value, which is evaluated on a pool-level basis. The fair value of loans held for sale is determined using quoted prices for similar assets, adjusted for specific attributes of that loan or other observable market data, such as outstanding commitments from third party investors (Level 2). Impaired Loans: The fair value of impaired loans with specific allocations of the allowance for loan losses is generally 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 for similar loans and collateral underlying such loans. 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 in accordance with the allowance policy. Other Real Estate Owned: 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. These assets are subsequently accounted for at lower of cost or fair value less estimated costs to sell. Fair value is commonly based on recent real estate appraisals which are updated no less frequently than annually. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach with data from comparable properties. Adjustments are routinely made in the appraisal process by the independent appraisers to adjust for differences between the comparable sales and income data available. Real estate owned properties are evaluated on a quarterly basis for additional impairment and adjusted accordingly. Mortgage Servicing Rights : On a quarterly basis, loan servicing rights are evaluated for impairment based upon the fair value of the rights as compared to carrying amount. The fair values of mortgage servicing rights are based on a valuation model that calculates the present value of estimated net servicing income. The valuation model incorporates assumptions that market participants would use in estimating future net servicing income. The Company is able to compare the valuation model inputs and results to widely available published industry data for reasonableness (Level 2). The following table sets forth the Company’s financial assets that were accounted for at fair value and are classified in their entirety based on the lowest level of input that is significant to the fair value measurement.

There was a decrease in the provision for loan losses of $19,000 for the three months ended March 31, 2015 . Other real estate owned ("OREO"), which is carried at the lower of cost or fair value less costs to sell, had a carrying value of $916,000 less a valuation allowance of $242,000 , or $674,000 at March 31, 2016 , compared to a carrying value of $2.5 million less a valuation allowance of $881,000 , or $1.7 million at December 31, 2015 . There were $119,000 of valuation adjustments of OREO recorded for the three months ended March 31, 2016 . There were $213,000 of valuation adjustments of OREO recorded for the three months ended March 31, 2015.

Loans : The estimated fair value for loans has been determined by calculating the present value of future cash flows based on the current rate the Company would charge for similar loans with similar maturities, applied for an estimated time period until the loan is assumed to be repriced or repaid. The estimated fair values of loans held for sale are based on quoted market prices. FHLBC Stock : It is not practicable to determine the fair value of FHLBC stock due to the restrictions placed on its transferability. Deposit Liabilities : The estimated fair value for certificates of deposit has been determined by calculating the present value of future cash flows based on estimates of rates the Company would pay on such deposits, applied for the time period until maturity. The estimated fair values of noninterest-bearing demand, NOW, money market, and savings deposits are assumed to approximate their carrying values as management establishes rates on these deposits at a level that approximates the local market area. Additionally, these deposits can be withdrawn on demand. Borrowings : The estimated fair values of advances from the FHLBC and notes payable are based on current market rates for similar financing. The estimated fair value of securities sold under agreements to repurchase is assumed to equal its carrying value due to the short-term nature of the liability. Accrued Interest : The estimated fair values of accrued interest receivable and payable are assumed to equal their carrying value. Off - Balance-Sheet Instruments : Off-balance-sheet items consist principally of unfunded loan commitments, standby letters of credit, and unused lines of credit. The estimated fair values of unfunded loan commitments, standby letters of credit, and unused lines of credit are not material. While the above estimates are based on management’s judgment of the most appropriate factors, as of the balance sheet date, there is no assurance that the estimated fair values would have been realized if the assets were disposed of or the liabilities settled at that date, since market values may differ depending on the various circumstances. The estimated fair values would also not apply to subsequent dates. In addition, other assets and liabilities that are not financial instruments, such as premises and equipment, are not included in the above disclosures.

Other Real Estate [Abstract]
Real Estate Owned [Text Block]	Real estate that is acquired through foreclosure or a deed in lieu of foreclosure is classified as other real estate owned ("OREO") until it is sold. When real estate is acquired through foreclosure or by deed in lieu of foreclosure, it is recorded at its fair value, less the estimated costs of disposal. If the fair value of the property is less than the loan balance, the difference is charged against the allowance for loan losses.

Basis of Presentation	Basis of Presentation : BankFinancial Corporation, a Maryland corporation headquartered in Burr Ridge, Illinois, is the owner of all of the issued and outstanding capital stock of BankFinancial, F.S.B. (the “Bank”).
Principles of Consolidation	The interim unaudited consolidated financial statements include the accounts of and transactions of BankFinancial Corporation, the Bank, and the Bank’s wholly-owned subsidiaries, Financial Assurance Services, Inc. and BF Asset Recovery Corporation (collectively, “the Company”), and reflect all normal and recurring adjustments that are, in the opinion of management, considered necessary for a fair presentation of the financial condition and results of operations for the periods presented. All significant intercompany accounts and transactions have been eliminated. The results of operations for the three- month period ended March 31, 2016 are not necessarily indicative of the results of operations that may be expected for the year ending December 31, 2016. Certain information and note disclosures normally included in financial statements prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”) have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission. Use of Estimate
Use of Estimates	Use of Estimates : To prepare financial statements in conformity with GAAP, management makes estimates and assumptions based on available information. These estimates and assumptions affect the amounts reported in the financial statements and the disclosures provided, and future results could differ.
Uncollected Interest Policy	The Company’s reserve for uncollected loan interest was $221,000 and $181,000 at March 31, 2016 and December 31, 2015 , respectively. When a loan is on non-accrual status and the ultimate collectability of the total principal of an impaired loan is in doubt, all payments are applied to principal under the cost recovery method. Alternatively, when a loan is on non-accrual status but there is doubt concerning only the ultimate collectability of interest, contractual interest is credited to interest income only when received, under the cash basis method pursuant to the provisions of FASB ASC 310–10, as applicable. In all cases, the average balances are calculated based on the month–end balances of the financing receivables within the period reported pursuant to the provisions of FASB ASC 310–10, as applicable.
Reclassifications	Reclassifications : Certain reclassifications have been made in the prior period’s financial statements to conform them to the current period’s presentation.

Recent Accounting Pronouncements	Recent Accounting Pronouncements 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 originally were to become effective for annual periods and interim periods within those annual periods beginning after December 15, 2016. During 2015, FASB delayed the effectiveness by one year to annual periods and interim periods beginning after December 15, 2017. We are currently evaluating the impact of adopting the new guidance on the consolidated financial statements. On January 5, 2016, the FASB issued an update (ASU No. 2016-01, Financial Instruments - Recognition and Measurement of Financial Assets and Liabilities). The new guidance is intended to improve the recognition and measurement of financial instruments by requiring: equity investments (other than equity method or consolidation) to be measured at fair value with changes in fair value recognized in net income; public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes; separate presentation of financial assets and financial liabilities by measurement category and form of financial assets (i.e. securities or loans and receivables) on the balance sheet or the accompanying notes to the financial statements; eliminating the requirement to disclose the fair value of financial instruments measured at amortized cost for organizations that are not public business entities; eliminating the requirement for non-public business entities to disclose the method(s) and significant assumptions used to estimate the fair value that is to be required to be disclosed for financial instruments measured at amortized cost on the balance sheet; and requiring a reporting organization to present separately in other comprehensive income the portion of the total change in fair value of a liability resulting from the change in the instrument-specific credit risk (also referred to as “own credit”) when the organization has elected to measure the liability at fair value in accordance with the fair value option for financial instruments. The new guidance is effective for public business entities for fiscal years beginning after December 15, 2017. We are currently evaluating the impact of adopting the new guidance on the consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, “Leases (Topic 842)” (“ASU 2016-02”). The standard requires a lessee to recognize assets and liabilities on the balance sheet for leases with lease terms greater than 12 months. ASU 2016-02 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2018, and early adoption is permitted. We are currently evaluating the impact that the standard will have on our consolidated financial statements. In March 2016, the FASB issued ASU No. 2016-09, “Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting” (“ASU 2016-09”). The standard is intended to simplify several areas of accounting for share-based compensation arrangements, including the income tax impact, classification on the statement of cash flows and forfeitures. ASU 2016-09 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2016, and early adoption is permitted. We are currently evaluating the impact that the standard will have on our consolidated financial statements.

Certain residential mortgage-backed securities and certain collateralized mortgage obligations that the Company holds in its investment portfolio were in an unrealized loss position at March 31, 2016 , but the unrealized losses were not considered significant under the Company’s impairment testing methodology. In addition, the Company does not intend to sell these securities, and it is likely that the Company will not be required to sell these securities before their anticipated recovery occurs.

In general, if the Company grants a loan extension or modification to a borrower for other than an insignificant period of time that includes a below–market interest rate, principal forgiveness, payment forbearance or other concession intended to minimize the economic loss to the Company, the loan extension or loan modification is classified as a TDR. In cases where borrowers are granted new terms that provide for a reduction of either interest or principal then due and payable, management measures any impairment on the restructured loan in the same manner as for impaired loans as noted above. The Company had $419,000 of TDRs at March 31, 2016 compared to $2.7 million at December 31, 2015 , with no specific valuation reserves allocated to those loans at March 31, 2016 and December 31, 2015 . The Company had no outstanding commitments to borrowers whose loans were classified as TDRs at either date. During the first quarter of 2016, six loans totaling $1.5 million were declassified as TDRs as they successfully met the regulatory criteria to be removed from TDR status. The following table presents loans classified as TDRs: March 31, 2016 December 31, 2015 One-to-four family residential real estate $ 248 $ 1,385 Multi-family mortgage — 1,119 Troubled debt restructured loans – accrual loans 248 2,504 One-to-four family residential real estate 171 174 Troubled debt restructured loans – nonaccrual loans 171 174 Total troubled debt restructured loans $ 419 $ 2,678 During the three months ending March 31, 2016 and 2015 , the terms of certain loans were modified and classified as TDRs. The modification of the terms of such loans included one or a combination of the following: a reduction of the stated interest rate of the loan; an extension of the maturity date at a stated rate of interest lower than the current market rate for new debt with similar risk; or a permanent reduction of the recorded investment in the loan.

The TDRs had no material impact on interest income, resulted in no change to the allowance for loan losses allocated and resulted in no charge-offs for the three months ended March 31, 2015 . The following table presents TDRs for which there was a payment default during the three months ending March 31, 2016 and 2015 within twelve months following the modification. 2016 2015 Number of loans Recorded investment Number of loans Recorded investment One-to-four family residential real estate 2 $ 42 2 $ 78 A loan is considered to be in payment default once it is 90 days contractually past due under the modified terms. The TDRs for which there was a payment default resulted in no change to the allowance for loan losses allocated and resulted in no charge-offs during the three months ending March 31, 2016 and 2015. There were no other loan modifications for the three months ending March 31, 2016 . There were certain other loan modifications during the three months ending March 31, 2015 that did not meet the definition of a TDR. These loans had a total recorded investment of $1.1 million at March 31, 2015 . The modification of these loans involved either a modification of the terms of a loan to borrowers who were not experiencing financial difficulties or a delay in a payment that was considered to be insignificant. 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 debt in the foreseeable future without the modification. This evaluation is performed under the Company’s internal underwriting policy. The Company categorizes loans into risk categories based on relevant information about the ability of borrowers to service their debt, including current financial information, historical payment experience, credit documentation, public information, and current economic trends, among other factors. The Company analyzes loans individually by classifying the loans based on credit risk. This analysis includes non-homogeneous loans, such as commercial and commercial real estate loans. This analysis is performed on a monthly basis. The Company uses the following definitions for risk ratings: Special Mention. A Special Mention asset has potential weaknesses that deserve management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the asset or in the institution’s credit position at some future date. Special Mention assets are not adversely classified and do not expose an institution to sufficient risk to warrant adverse classification. Substandard. Loans categorized as Substandard continue to accrue interest, but exhibit a well-defined weakness or weaknesses that may jeopardize the liquidation of the debt. The loans continue to accrue interest because they are well secured and collection of principal and interest is expected within a reasonable time. The risk rating guidance published by the Office of the Comptroller of the Currency clarifies that a loan with a well-defined weakness does not have to present a probability of default for the loan to be rated Substandard, and that an individual loan’s loss potential does not have to be distinct for the loan to be rated Substandard. Nonaccrual. An asset classified Nonaccrual has all the weaknesses inherent in one classified 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. The loans were placed on nonaccrual status. Loans not meeting the criteria above that are analyzed individually as part of the above described process are considered “Pass” rated loans. As of March 31, 2016 , based on the most recent analysis performed, the risk categories of loans by class of loans are as follows: Pass Special Mention Substandard Nonaccrual Total One-to-four family residential real estate loans $ 107,638 $ — $ 328 $ 3,178 $ 111,144 One-to-four family residential real estate loans – non-owner occupied 42,923 217 112 192 43,444 Multi-family mortgage loans - Illinois 311,205 339 2,838 956 315,338 Multi-family mortgage loans - Other 197,603 — 509 — 198,112 Nonresidential real estate loans 212,474 1,590 4,981 294 219,339 Construction loans 545 — — — 545 Land loans 427 — — 827 1,254 Commercial loans: Regional commercial banking 27,688 — 137 — 27,825 Health care 31,426 — — — 31,426 Direct commercial lessor 16,196 878 — — 17,074 Commercial leases: Investment rated commercial leases 182,057 — — — 182,057 Other commercial leases 90,530 262 — — 90,792 Consumer 1,890 — — — 1,890 $ 1,222,602 $ 3,286 $ 8,905 $ 5,447 $ 1,240,240 As of December 31, 2015 , based on the most recent analysis performed, the risk categories of loans by class of loans are as follows: Pass Special Mention Substandard Nonaccrual Total One-to-four family residential real estate loans $ 112,449 $ — $ 576 $ 1,936 $ 114,961 One-to-four family residential real estate loans – non-owner occupied 43,858 219 271 192 44,540 Multi-family mortgage loans - Illinois 312,329 344 4,656 828 318,157 Multi-family mortgage loans - Other 187,358 — 511 — 187,869 Nonresidential real estate loans 219,859 1,600 4,981 295 226,735 Construction loans 21 — — — 21 Land loans 450 — 842 — 1,292 Commercial loans: Regional commercial banking 29,377 — 614 — 29,991 Health care 31,809 — — — 31,809 Direct commercial lessor 17,716 — — — 17,716 Commercial leases: — Investment rated commercial leases 170,100 — — — 170,100 Other commercial leases 95,305 — — — 95,305 Consumer 1,831 — — — 1,831 $ 1,222,462 $ 2,163 $ 12,451 $ 3,251 $ 1,240,327
