Summary Of Significant Accounting Policies [Abstract]
Summary Of Significant Accounting Policies	 NO TE 1 – SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Nature of Operations and Principles of Consolidation : The consolidated financial statements include Central Federal Corporation (the “Holding Company”) and its wholly-owned subsidiary, CFBank , National Association (“CFBank”) . On December 1, 2016, CFBank converted from a federal savings institution to a national bank. The Holding Company and CFBank are sometimes collectively referred to her e in as the “Company”. Intercompany transactions and balances are eliminated in consolidation. CFBank provides financial services through its five full-service banking offices in Worthington, Fairlawn, Glendale, Calcutta, and Wellsville, Ohio, and through its agency office in Woodmere, Ohio. Its primary deposit products are commercial and retail checking, savings, money market and term certificate accounts. Its primary lending products are commercial and commercial real estate, residential mortgages and installment loans. There are no significant concentrations of loans to any one industry or customer segment. However, our customers’ ability to repay their loans is dependent on general economic conditions and the real estate values in their geographic areas. Use of Estimates : To prepare financial statements in conformity with U.S. generally accepted accounting principles (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 actual results could differ. The allowance for loan and lease losses (ALLL), deferred tax assets and fair values of financial instruments are particularly subject to change. Cash Flows : Cash and cash equivalents include cash, deposits with other financial institutions with maturities fewer than 90 days and federal funds sold. Net cash flows are reported for customer loan and deposit transactions, interest-bearing deposits in other financial institutions and borrowings with original maturities under 90 days. Interest-Bearing Deposits in Other Financial Institutions : Interest ‑bearing deposits in other financial institutions mature in April, 2019 and are carried at cost. As of December 31, 2017 and December 31, 201 6 , there was $100 in an interest-bearing deposit in other financial institutions. Securities : Debt securities are classified as available for sale when they might be sold before maturity. Equity securities with readily determinable fair values are classified as available for sale. Securities available for sale are carried at fair value, with unrealized holding gains and losses reported in other comprehensive income. Interest income includes amortization of purchase premium or accretion of discount. Premiums and discounts on securities are amortized or accreted on the level-yield method, except for mortgage-backed securities and collateralized mortgage obligations where prepayments are anticipated based on industry payment trends. Gains and losses on sales are recorded on the trade date and determined using the specific identification method. Management evaluates securities for other-than-temporary impairment (OTTI) at least on a quarterly basis, and more frequently when economic or market conditions warrant such an evaluation. For securities in an unrealized loss position, management considers the extent and duration of the unrealized loss and the financial condition and near-term prospects of the issuer. Management also assesses whether it intends to sell, or will more likely than not be required to sell, a security in an unrealized loss position before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the entire difference between amortized cost and fair value is recognized as impairment through earnings. For debt securities that do not meet the aforementioned criteria, the amount of impairment is split into two components as follows: 1) OTTI related to credit loss, which must be recognized in the income statement and 2) OTTI related to other factors, which is recognized in other comprehensive income. The credit loss is defined as the difference between the present value of the cash flows expected to be collected and the amortized cost basis. For equity securities, the entire amount of impairment is recognized through earnings. Loans Held for Sale : Mortgage loans originated and intended for sale in the secondary market are carried at fair value, as determined by outstanding commitments from investors. Mortgage loans held for sale are generally sold with servicing rights released. The carrying value of mortgage loans sold is reduced by the amount allocated to the servicing rights when mortgage loans held for sale are sold with servicing rights retained. Loans originated as construction loans, that were subsequently transferred to held for sale, are carried at the lower of cost or market. Gains and losses on sales of mortgage loans are based on the difference between the selling price and the carrying value of the related loan sold.  Loans and Leases : Loans and leases that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at the principal balance outstanding, adjusted for purchase premiums and discounts, deferred loan fees and costs and an allowance for loan and lease losses (ALLL). Interest income is accrued on the unpaid principal balance. Loan origination fees, net of certain direct origination costs, are deferred and recognized in interest income using the level ‑yield method without anticipating prepayments. The accrual of interest income on all classes of loans, except other consumer loans, is discontinued and the loan is placed on nonaccrual status at the time the loan is 90 days delinquent unless the loan is well-secured and in process of collection. Other consumer loans are typically charged off no later than 90 days past due. Past due status is based on the contractual terms of the loan for all classes of loans. In all cases, loans are placed on nonaccrual or charged-off at an earlier date if collection of principal or interest is considered doubtful. Nonaccrual loans and loans past due 90 days still on accrual include both smaller balance homogeneous loans that are collectively evaluated for impairment and individually classified impaired loans. Commercial, multi-family residential real estate loans and commercial real estate loans placed on nonaccrual status are individually classified as impaired loans. All interest accrued but not received for each loan placed on nonaccrual is reversed against interest income in the period in which it is placed in a nonaccrual status. Interest received on such loans is accounted for on the cash-basis or cost ‑recovery method, until qualifying for return to accrual status. Loans are considered for return to accrual status provided all the principal and interest amounts that are contractually due are brought current, there is a current and well documented credit analysis, there is reasonable assurance of repayment of principal and interest, and the customer has demonstrated sustained, amortizing payment performance of at least six months. Concentration of Credit Risk : Most of the Company’s primary business activity is with customers located within the Ohio counties of Franklin, Hamilton, Cuyahoga , Summit , Columbiana and contiguous counties. Therefore, the Company’s exposure to credit risk can be affected by changes in the economies within these counties. Although these counties are the Company’s primary market area for loans, the Company originates residential and commercial real estate loans throughout the United States. Allowance for Loan and Lease Losses (ALLL) : The ALLL is a valuation allowance for probable incurred credit losses. Loan losses are charged against the allowance when management believes the uncollectibility of a loan balance is confirmed. Subsequent recoveries, if any, are credited to the allowance. Management estimates the allowance balance required using past loan loss experience, the nature and volume of the portfolio, information about specific borrower situations and estimated collateral values, economic conditions, and other factors. Allocations of the allowance may be made for specific loans, but the entire allowance is available for any loan that, in management’s judgment, should be charged off. The allowance consists of specific and general components. The specific component relates to loans that are individually classified as impaired. A loan is impaired when, based on current information and events, it is probable that CFBank will be unable to collect all amounts due according to the contractual terms of the loan agreement. Loans within any loan class for which the terms have been modified resulting in a concession, and for which the borrower is experiencing financial difficulties, are considered troubled debt restructurings (TDRs) and classified as impaired. Factors considered by management in determining impairment for all loan classes include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record and the amount of the shortfall in relation to the principal and interest owed. All loans within the commercial, multi-family residential and commercial real estate segments, regardless of size, and loans of all other classes with balances over $250 are individually evaluated for impairment when they are 90 days past due, or earlier than 90 days past due if information regarding the payment capacity of the borrower indicates that payment in full according to the loan terms is doubtful. If a loan is impaired, a portion of the allowance is allocated so that the loan is reported, net, at the present value of estimated future cash flows using the loan’s existing rate, or at the fair value of collateral, less costs to sell, if repayment is expected solely from the collateral. Large groups of smaller balance homogeneous loans, such as consumer and single-family residential real estate loans, are collectively evaluated for impairment, and accordingly, they are not separately identified for impairment disclosures.  TDRs of all classes of loans are separately identified for impairment disclosures and are measured at the present value of estimated future cash flows using each loan’s effective rate at inception. If a TDR is considered to be a collateral dependent loan, the loan is reported, net, at the fair value of the collateral. If the payment of the loan is dependent on the sale of the collateral, then costs to liquidate the collateral are included when determining the impairment. For TDRs that subsequently default, the amount of reserve is determined in accordance with the accounting policy for the ALLL. Interest income on all classes of impaired loans that are on nonaccrual status is recognized in accordance with the accounting policy for nonaccrual loans. Cash receipts on all classes of impaired loans that are on nonaccrual status are generally applied to the principal balance outstanding. Interest income on all classes of impaired loans that are not on nonaccrual status is recognized on the accrual method. TDRs may be classified as accruing if the borrower has been current for a period of at least six months with respect to loan payments and management expects that the borrower will be able to continue to make payments in accordance with the terms of the restructured note. The general reserve component covers non ‑impaired loans of all classes and is based on historical loss experience adjusted for current factors. The historical loss experience is determined by loan class and is based on the actual loss history experienced by the Company over a three-year period. The general component is calculated based on CFBank’s loan balances and actual historical three-year historical loss rates. For loans with little or no actual loss experience, industry estimates are used based on loan segment. This loss experience is supplemented with other economic and judgmental factors based on the risks present for each loan class. These economic and judgmental factors include consideration of the following: levels of and trends in delinquencies and impaired loans; levels of and trends in charge-offs and recoveries; trends in volume and terms of loans; effects of any changes in risk selection and underwriting standards; other changes in lending policies, procedures, and practices; experience, ability, and depth of lending management and other relevant staff; national and local economic trends and conditions; industry conditions; and effects of changes in credit concentrations. The following portfolio segments have been identified: commercial loans ; single-family residential real estate loans; multi-family residential real estate loans; commercial real estate loans; construction loans; home equity lines of credit; and other consumer loans. A description of each segment of the loan portfolio, along with the risk characteristics of each segment , is included below . Commercial loans: Commercial loans include loans to businesses generally located within our primary market area. Those loans are generally secured by business equipment, inventory, accounts receivable and other business assets. In underwriting commercial loans, we consider the net operating income of the borrower , the debt service ratio and the financial strength, expertise and credit history of the business owners and/or guarantors. Because payments on commercial loans are dependent on successful operation of the business enterprise, repayment of such loans may be subject to a greater extent to adverse conditions in the economy. We seek to mitigate these risks through underwriting policies which require such loans to be qualified at origination on the basis of the borrower ’s financial performance and the financial strength of the business owners and/or guarantors. Single-family residential real estate loans: Single-family residential real estate loans include permanent conventional mortgage loans secured by single-family residences located within and outside of our primary market area. Credit approval for single-family residential real estate loans requires demonstration of sufficient income to repay the principal and interest and the real estate taxes and insurance, stability of employment and an established credit record. Our policy is to originate single-family residential real estate loans for portfolio in amounts up to 85% of the lower of the appraised value or the purchase price of the property securing the loan, without requiring private mortgage insurance. Loans in excess of 85% of the lower of the appraised value or purchase price of the property securing the loan require private mortgage insurance. CFBank has not engaged in subprime lending or used option adjustable-rate mortgage products. Multi-family residential real estate loans: Multi-family residential real estate loans include loans secured by apartment buildings, condominiums and multi-family residential houses generally located within our primary market area. Underwriting policies provide that multi-family residential real estate loans may be made in amounts up to 85% of the lower of the appraised value or purchase price of the property. In underwriting multi-family residential real estate loans, we consider the appraised value and net operating income of the property, the debt service ratio and the property owner’s and/or guarantor’s financial strength, expertise and credit history. We offer both fixed-rate and adjustable-rate loans. Fixed-rate loans are generally limited to three to five years, at which time they convert to adjustable-rate loans. Because payments on loans secured by multi-family residential properties are dependent on successful operation or management of the properties, repayment of multi-family residential real estate loans may be subject to a greater extent to adverse conditions in the real estate market or the economy. Adjustable-rate multi-family residential real estate loans generally pose credit risks not inherent in fixed-rate loans, primarily because as interest rates rise, the borrowers’ payments rise, increasing the potential for default. Additionally, adjustable-rate multi-family residential real estate loans generally do not contain periodic and lifetime caps on interest rate changes. We seek to minimize the additional risk presented by adjustable-rate multi-family residential real estate loans through underwriting criteria that require such loans to be qualified at origination with sufficient debt coverage ratios under increasing interest rate scenarios.  Commercial real estate loans: Commercial real estate loans include loans secured by owner occupied and non-owner occupied properties used for business purposes, such as manufacturing facilities, office buildings or retail facilities generally located within our primary market area. Underwriting policies provide that commercial real estate loans may be made in amounts up to 85% of the lower of the appraised value or purchase price of the property. In underwriting commercial real estate loans, we consider the appraised value and net operating income of the property, the debt service ratio and the property owner’s and/or guarantor’s financial strength, expertise and credit history. We offer both fixed and adjustable-rate loans. Fixed-rate loans are generally limited to three to five years, at which time they convert to adjustable-rate loans. Because payments on loans secured by commercial real estate properties are dependent on successful operation or management of the properties, repayment of commercial real estate loans may be subject to a greater extent to adverse conditions in the real estate market or the economy. Adjustable-rate commercial real estate loans generally pose credit risks not inherent in fixed-rate loans, primarily because as interest rates rise, the borrowers’ payments rise, increasing the potential for default. Additionally, adjustable-rate commercial real estate loans generally do not contain periodic and lifetime caps on interest rate changes. We seek to minimize the additional risk presented by adjustable-rate commercial real estate loans through underwriting criteria that require such loans to be qualified at origination with sufficient debt coverage ratios under increasing interest rate scenarios. Construction loans: Construction loans include loans to finance the construction of residential and commercial properties generally located within our primary market area. Construction loans are fixed-rate or adjustable-rate loans which may convert to permanent loans with maturities of up to 30 years. Our policies provide that construction loans may be made in amounts up to 80% of the appraised value of the property, and an independent appraisal of the property is required. Loan proceeds are disbursed in increments as construction progresses and as inspections warrant, and regular inspections are required to monitor the progress of construction. In underwriting construction loans, we consider the property owner’s and/or guarantor’s financial strength, expertise and credit history. Construction financing is considered to involve a higher degree of credit risk than long-term financing on improved, owner occupied real estate. Risk of loss on a construction loan is dependent largely upon the accuracy of the initial estimate of the property’s value at completion of construction or development compared to the estimated cost (including interest) of construction. If the estimate of value proves to be inaccurate, we may be confronted with a project, when completed, having a value which is insufficient to assure full repayment. We attempt to reduce such risks on construction loans through inspections of construction progress on the property and by requiring personal guarantees and reviewing current personal financial statements and tax returns, as well as other projects of the developer. Home equity lines of credit: Home equity lines of credit include both loans we originate for portfolio and purchased loans. We originate home equity lines of credit to customers generally within our primary market area. Home equity lines of credit are variable rate loans and the interest rate adjusts monthly at various margins above the prime rate of interest as disclosed in The Wall Street Journal. The margin is based on certain factors including the loan balance, value of collateral, election of auto-payment, and the borrower’s FICO® score. The amount of the line is based on the borrower’s credit, income and equity in the home. When combined with the balance of the prior mortgage liens, these lines generally may not exceed 89.9% of the appraised value of the property at the time of the loan commitment. The lines are secured by a subordinate lien on the underlying real estate and are, therefore, vulnerable to declines in property values in the geographic areas where the properties are located. Credit approval for home equity lines of credit requires income sufficient to repay principal and interest due, stability of employment, an established credit record and sufficient collateral. Collectability of home equity lines of credit are dependent on the borrower's continuing financial stability, and thus are more likely to be affected by adverse personal circumstances. We continue to monitor collateral values and borrower FICO® scores on both purchased and portfolio loans and, when the situation warrants, have frozen the lines of credit. Other consumer loans: Other consumer loans include closed-end home equity, home improvement, and auto and credit card loans to consumers generally located within our primary market area. Credit approval for other consumer loans requires income sufficient to repay principal and interest due, stability of employment, an established credit record and sufficient collateral for secured loans. Consumer loans typically have shorter terms and lower balances with higher yields as compared to real estate mortgage loans, but generally carry higher risks of default. Consumer loan collections are dependent on the borrower's continuing financial stability, and thus are more likely to be affected by adverse personal circumstances. CFBank’s charge-off policy for commercial loans, single-family residential real estate loans, multi-family residential real estate loans, commercial real estate loans, construction loans and home equity lines of credit requires management to record a specific reserve or charge-off as soon as it is apparent that the borrower is troubled and there is, or likely will be a collateral shortfall related to the estimated value of the collateral securing the loan. Other consumer loans are typically charged off no later than 90 days past due.  Transfers of Financial Assets : Transfers of financial assets are accounted for as sales when control over the assets has been relinquished. Control over transferred assets is deemed to be surrendered when the assets have been isolated from the Company, the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity. Foreclosed Assets : 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. If fair value declines subsequent to foreclosure, an adjustment is recorded through expense. Operating costs after acquisition are expensed. Low Income Housing Tax Credits (LIHTC): The Company has invested in low income housing tax credits through a fund that assists corporations in investing in limited partnerships and limited liability companies that own, develop and operate low income residential rental properties for purposes of qualifying for the Housing Tax credit. These investments are accounted for under the proportional amortization method which recognizes the amortization of the investment in proportion to the tax credit and other tax benefits received. Joint Ventures: The Holding Company contributed funds into a series of joint ventures (equity stake) for the purpose of allocating excess liquidity into higher earning assets while diversifying its revenue sources. The funding for the joint ventures is related to shorter term operating activities and is related to the development of single family real estate in the form of condominiums. Income is recognized based on a rate of return on the outstanding investment balance. As units are sold, the Holding Company receives an additional incentive payment, which is recognized as income. The balance outstanding in joint ventures at December 31, 2017 and December 31, 2016 was $325 and $325 , respectively. Income recognized on the joint ventures was $20 and $100 , respectively, for 2017 and 2016. Premises and Equipment : Land is carried at cost. Premises and equipment are stated at cost less accumulated depreciation. Buildings and related components are depreciated using the straight ‑line method with useful lives ranging from 3 to 40 years. Furniture, fixtures and equipment are depreciated using the straight ‑line method with useful lives ranging from 2 to 25 years. Leasehold improvements are depreciated straight-line over the shorter of the useful life or the lease term. Federal Home Loan Bank (FHLB) stock: CFBank is a member of the FHLB system. Members are required to own a certain amount of stock based on the level of borrowings and other factors, and may invest in additional amounts. FHLB stock is carried at cost, classified as a restricted security, and periodically evaluated for impairment based on ultimate recovery of par value. Both cash and stock dividends are reported as income. Federal Reserve Bank (F R B) stock: CFBank is a member of the FRB s ystem and is required to own a certain amount of stock. FRB stock is carried at cost, classified as a restricted security, and periodically evaluated for impairment based on ultimate recovery of par value. Both cash and stock dividends are reported as income. Bank Owned Life Insurance : CFBank purchased life insurance policies on certain directors and employees in 2002. Bank owned life insurance is recorded at the amount that can be realized under the insurance contract at the balance sheet date, which is the cash surrender value adjusted for other charges or other amounts due that are probable at settlement. Loan Commitments and Related Financial Instruments : Financial instruments include off ‑balance-sheet credit instruments, such as commitments to make loans and commercial letters of credit, issued to meet customer financing needs. The face amount for these items represents the exposure to loss, before considering customer collateral or ability to repay. Such financial instruments are recorded when they are funded, and fees associated with origination are booked to non-interest income at the origination date. Derivatives : Derivative financial instruments are recognized as assets or liabilities at fair value. The Company's derivatives consist mainly of interest rate swap agreements, which are used as part of its asset liability management program to help manage interest rate risk. The Company does not use derivatives for trading purposes. The derivative transactions are considered instruments with no hedging designation, otherwise known as stand-alone derivatives. Changes in the fair value of the derivatives are reported currently in earnings, as other noninterest income. Mortgage Banking Derivatives : Commitments to fund mortgage loans to be sold into the secondary market, otherwise known as interest rate locks, are accounted for as free standing derivatives. Fair values of these mortgage derivatives are based on anticipated gains on the underlying loans. Changes in the fair values of these derivatives are included in net gains on sales of loans.  Stock-Based Compensation : Compensation cost is recognized for stock options and restricted stock awards issued to directors and employees, based on the fair value of these awards at the date of grant. A Black-Scholes model is utilized to estimate the fair value of stock options, while the market price of the Company’s common stock at the date of grant is used for restricted stock awards. Compensation cost is recognized over the required service period, generally defined as the vesting period. For awards with graded vesting, compensation cost is recognized on a straight-line basis over the required service period for each separately vesting portion of the award. Income Taxes : Income tax expense is the total of the current year income tax due or refundable and the change in deferred tax assets and liabilities. Deferred tax assets and liabilities are the expected future tax amounts for the temporary differences between carrying amounts and tax basis of assets and liabilities, computed using enacted tax rates. A tax position is recognized as a benefit only if it is “more likely than not” that the tax position would be sustained in a tax examination, with a tax examination being presumed to occur. The amount recognized is the largest amount of tax benefit that is greater than 50% likely of being realized on examination. For tax positions not meeting the “more likely than not” test, no tax benefit is recorded. The Company recognizes interest related to income tax matters as interest expense and penalties related to income tax matters as other noninterest expense. Retirement Plans : Pension expense is the amount of annual contributions by the Company to the multi-employer contributory trusteed pension plan. Employee 401(k) and profit sharing plan expense is the amount of matching contributions. Supplemental retirement plan expense allocates the benefits over years of service. Earnings Per Common Share : Basic earnings per common share is net income available to common stockholders divided by the weighted average number of common shares outstanding during the period. All outstanding unvested share-based payment awards that contain rights to nonforfeitable dividends are considered participating securities for this calculation. Diluted earnings per common share includes the dilutive effect of additional potential common shares issuable under stock options. Comprehensive Income (Loss) : Comprehensive income (loss) consists of net income (loss) and other comprehensive income (loss). Other comprehensive income (loss) includes unrealized gains and losses on securities available for sale, which are also recognized as a separate component of equity. Loss Contingencies : Loss contingencies, including claims and legal actions arising in the ordinary course of business, are recorded as liabilities when the likelihood of loss is probable and an amount or range of loss can be reasonably estimated. Management does not believe there are any such matters that will have a material effect on the financial statements. See Note 24 – Contingent Liabilities. Restrictions on Cash : Cash on hand or on deposit with the Federal Reserve Bank (FRB) is required to meet regulatory reserve and clearing requirements. The reserve requirement at December 31, 2017 and December 31, 2016 was $718 and $267 , respectively . Cash on deposit with the FHLB includes $3,300 pledged as collateral for FHLB advances. Equity : Treasury stock is carried at cost. The carrying value of preferred stock and the common stock warrant is based on allocation of issuance proceeds, net of issuance costs, in proportion to their relative fair values. Preferred stock is carried net of the discount established through the allocation of proceeds. Dividend Restriction : Banking regulations require us to maintain certain capital levels and may limit the dividends paid by CFBank to the Holding Company or by the Holding Company to stockholders. The ability of the Holding Company to pay divide

Regulatory Matters [Abstract]
Regulatory Matters	 NOTE 2- REGULATORY MATTERS Regulatory Matters : From May 2011 until 2014, the Holding Company and CFBank each were subject to Cease and Desist Orders (the “Holding Company Order” and the “CFBank Order”, respectively, and collectively, the “Orders”) with the FRB, as successor to the Office of Thrift Supervision (the “OTS”) as the primary regulator of the Holding Company and CFBank. The Orders imposed significant directives applicable to the Holding Company and CFBank, including requirements that we maintain heightened capital levels, reduce the level of our classified and criticized assets, achieve growth and operating metrics in line with an approved business plan, and comply with restrictions on brokered deposits and on certain types of lending and prohibitions on dividends and repurchases of our capital stock. The OCC released and terminated the CFBank Order effective as of January 23, 2014. On May 15, 2014, the FRB announced the termination of the Holding Company Order, effective as of May 9, 2014. Notwithstanding the termination of the Holding Company Order, the Holding Company was required to continue to adhere to certain requirements and restrictions based on commitments made to the FRB in connection with the termination of the Holding Company Order. These commitments required the Holding Company, among other things, to continue to implement certain actions in accordance with the capital plan previously submitted to the FRB; not declare or pay dividends on its stock, purchase or redeem its stock, or accept dividends or other capital distributions from CFBank without the prior written approval of the FRB; not incur, increase or guarantee any debt without the prior written consent of the FRB; and provide prior written notice to the FRB with respect to certain changes in directors and senior executive officers. The foregoing commitments remained in place until January 8, 2016. Although we are no longer subject to the Orders or the regulatory commitments made following the release of the Orders, we remain subject to extensive supervision and regulation by our regulators and it is possible that regulatory compliance expenses could continue to have an adverse impact on us in the future. Dividend Restrictions : The ability of the Holding Company to pay dividends on its outstanding stock is generally dependent upon the receipt of dividends and other distributions from CFBank. The Holding Company is a legal entity that is separate and distinct from CFBank, which has no obligation to make any dividends or other funds available for the payment of dividends by the Holding Company. The Holding Company also is subject to various legal and regulatory policies and guidelines impacting the Holding Company’s ability to pay dividends on its stock. In addition, the Holding Company’s ability to pay dividends on its stock is conditioned upon the payment, on a current basis, of quarterly interest payments on the subordinated debentures underlying the Company’s trust preferred securities. Effective October 6, 2017, all of its outstanding shares of Series B Preferred Stock were converted into shares of Common Stock of the Company. The conversion of the Series B Preferred Stock result ed in the elimination of the non-cumulative preferred dividend payments on the Series B Preferred Stock beginning with the 4th quarter of 2017. See Note 17 to our consolidated financial statements included in this annual repor t for additional information regarding the conversion of the Series B Preferred Stock.

The unrealized loss es in U.S. Treasuries at December 31, 2017 and U.S. Treasuries and Mortgage-backed securities at December 31, 201 6 , are related to multiple securities. Because the decline in fair value is attributable to changes in market conditions, and not credit quality, and because the Company does not have the intent to sell these securities and will unlikely be required to sell these securities before their anticipated recovery, the Company did not consider these securities to be other-than-temporarily impaired at December 31, 201 7 and December 31, 201 6 .

Loans And Leases	 NOTE 4 – LOANS AND LEASES The following table presents the recorded investment in loans and leases by portfolio segment. The recorded investment in loans and leases includes the principal balance outstanding adjusted for purchase premiums and discounts, and deferred loan fees and costs.

Mortgage Purchase Program : CFBank has participated in a Mortgage Purchase Program with Northpointe Bank (Northpointe), a Michigan banking corporation, since December 2012. Pursuant to the terms of a participation agreement, CFBank purchases participation interests in loans made by Northpointe related to fully underwritten and pre-sold mortgage loans originated by various prescreened mortgage brokers located throughout the U.S. The underlying loans are individually (MERS) registered loans which are held until funded by the end investor. The mortgage loan investors include Fannie Mae and Freddie Mac, and other major financial institutions. This process on average takes approximately 14 days. Given the short-term holding period of the underlying loans, common credit risks (such as past due, impairment and TDR, nonperforming, and nonaccrual classification) are substantially reduced. Therefore, no allowance is allocated by CFBank to these loans. These loans are 100% risk rated for CFBank capital adequacy purposes . Under the participation agreement, CFBank agrees to purchase a 95% ownership/participation interest in each of the aforementioned loans, and Northpointe maintains a 5% ownership interest in each loan it participates. At December 31, 201 7 and 201 6 , CFBank held $37,665 and $46,919 , respectively , of such loans which have been included in single-family residential loan totals above. Allowance for L oan and Lease L oss es: The ALLL is a valuation allowance for probable incurred credit losses in the loan and lease portfolio based on management’s evaluation of various factors including past loan loss experience, the nature and volume of the portfolio, information about specific borrower situations and estimated collateral values, economic conditions and other factors. A provision for loan and lease losses is charged to operations based on management’s periodic evaluation of these and other pertinent factors described in Note 1 of the Notes to Consolidated Financial Statements.

The modification of the terms of such loans may have included one or a combination of the following: a reduction of the stated interest rate of the loan; an increase in the stated rate of interest lower than the current market rate for new debt with similar risk; an extension of the maturity date; or a change in the payment terms. As of December 31, 201 7 and December 31, 201 6 , TDR’s totaled $3,386 and $3,130 , respectively.

There was one commercial real estate loan in the amount of $841 that was modified as a TDR during the year ended December 31, 2017, where concessions were granted to a borrower experiencing financial difficulty. The loan was re-written at a lower interest rate than otherwise would have been offered on this credit grade in the current market. There was one commercial loan in the amount of $239 that was modifi ed as TDRs during the year ended December 31, 2016, where concessions were granted to a borrower experiencing financial difficulties. The following table presents loans modified as TDRs by class of loans during the year ended December 31, 201 7 :    Number of Loans Pre-Modification Outstanding Recorded Investment Post-Modification Outstanding Recorded Investment  Commercial 1 $ 841 $ 841  Total 1 $ 841 $ 841   The following table presents loans modified as TDRs by class of loans during the year ended December 31, 201 6 :   Number of Loans Pre-Modification Outstanding Recorded Investment Post-Modification Outstanding Recorded Investment  Commercial 1 $ 339 $ 339  Total 1 $ 339 $ 339  The TDRs described above resulted in no charge-offs during the years ended December 31, 201 7 and 201 6, respectively . There were no TDR’s that went into payment default during the year ended December 31, 2017. There w as one nonperforming TDR that went into payment default during the year ending December 31, 2016 . The terms of certain other loans were modified during the year ended December 31, 201 7 and 201 6 that did not meet the definition of a TDR. These loans had a total recorded investment of $46,731 and $33,294 as of December 31, 201 7 and 201 6 , respectively. The modification of these loans involved either a modification of the terms of a loan to borrowers who were not experiencing financial difficulties, a delay in a payment that was considered to be insignificant or there were no concessions granted. 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. Nonaccrual loans include loans that were modified and identified as TDRs and the loans are not performing. At December 31, 201 7 and 201 6 , nonaccrual TDRs were as follows:     2017 2016  Commercial $ 115 $ 144  Total $ 115 $ 144  Nonaccrual loans at December 31, 201 7 and 201 6 did not include $3,271 and $2,986 , respectively, of TDRs where customers have established a sustained period of repayment performance, generally six months, the loans are current according to their modified terms and repayment of the remaining contractual payments is expected. These loans are included in total impaired loans. Credit Quality Indicators: The Company categorizes loans into risk categories based on relevant information about the ability of borrowers to service their debt, such as current financial information, historical payment experience, credit documentation, public information and current economic trends, among other factors. Management analyzes loans individually by classifying the loans as to credit risk. This analysis includes commercial, commercial real estate and multi-family residential real estate loans. Internal loan reviews for these loan types are performed at least annually, and more often for loans with higher credit risk. Adjustments to loan risk ratings are based on the reviews and at any time information is received that may affect risk ratings. The following definitions are used for risk ratings: Special Mention . 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 CFBank’s credit position at some future date. Substandard . 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 there will be some loss if the deficiencies are not corrected. Doubtful . 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, condition and values, highly questionable and improbable.  Loans not meeting the criteria to be classified into one of the above categories are considered to be not rated or pass-rated loans. Loans listed as not rated are included in groups of homogeneous loans. Past due information is the primary credit indicator for groups of homogenous loans. Loans listed as pass-rated loans are loans that are subject to internal loan reviews and are determined not to meet the criteria required to be classified as special mention, substandard, doubtful or loss. The recorded investment in loans and leases by risk category and by class of loans as of December 31, 201 7 and based on the most recent analysis performed follows.

Fair Value

Fair Value [Abstract]
Fair Value	NOTE 6 – FAIR VALUE F air value is the exchange price that would be received for an asset or paid to transfer a liability 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 asset and liability: Securities available for sale : The fair value of securities available for sale is determined using pricing models that vary based on asset class and include available trade, bid and other market information 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). Derivatives : The fair value of derivatives, which includes yield maintenance provisions, interest rate lock commitments and interest rate swaps, is based on valuation models using observable market data as of the measurement date (Level 2). Impaired loans : The fair value of impaired loans with specific allocations of the ALLL 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 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.  Appraisals for collateral-dependent impaired loans are performed by certified general appraisers (for commercial properties) or certified residential appraisers (for residential properties) whose qualifications and licenses have been reviewed and verified by a third-party appraisal management company approved by the Board of Directors annually. Once received, the loan officer or a member of the credit department reviews the assumptions and approaches utilized in the appraisal as well as the overall resulting fair value in comparison with independent data sources such as recent market data or industry-wide statistics. Appraisals are updated as needed based on facts and circumstances associated with the individual properties. Real estate appraisals typically incorporate measures such as recent sales prices for comparable properties. Appraisers may make adjustments to the sales prices of the comparable properties as deemed appropriate based on the age, condition or general characteristics of the subject property. Management applies an additional discount to real estate appraised values, typically to reflect changes in market conditions since the date of the appraisal and to cover disposition costs (including selling expenses) based on the intended disposition method of the property. 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. Loans held for sale: Loans held for sale are carried at fair value, as determined by outstanding commitments from third party investors (Level 2). Assets and liabilities measured at fair value on a recurring basis, including financial assets and liabilities for which the Company has elected the fair value option, are summarized below:   Fair Value Measurements at December 31, 2017 Using Significant Other Observable Inputs  (Level 2)  Financial Assets:  Securities available for sale:  Issued by U.S. government-sponsored entities and agencies:  U.S. Treasury $ 11,417  Mortgage-backed securities - residential 244  Collateralized mortgage obligations 112  Total securities available for sale $ 11,773   Loans held for sale $ 1,124   Yield maintenance provisions (embedded derivatives) $ 56   Interest rate lock commitments $ 11   Financial Liabilities:  Interest-rate swaps $ 56     Fair Value Measurements at December 31, 2016 Using Significant Other Observable Inputs  (Level 2)  Financial Assets:  Securities available for sale:  Issued by U.S. government-sponsored entities and agencies:  U.S. Treasury $ 13,505  Mortgage-backed securities - residential 357  Collateralized mortgage obligations 196  Total securities available for sale $ 14,058   Loans held for sale $ 2,812   Yield maintenance provisions (embedded derivatives) $ 122   Interest rate lock commitments $ 9   Financial Liabilities:  Interest-rate swaps $ 122  The Company had no assets or liabilities measured at fair value on a recurring basis that were measured using Level 1 or Level 3 inputs at December 31, 201 7 or December 31, 201 6 .

C ash and Cash Equivalents and Interest-Bearing Deposits in Other Financial Institutions The carrying amounts of cash and short-term instruments approximate fair values and are classified as Level 1. FHLB and FRB Stock It is not practical to determine the fair value of FHLB and FRB stock due to restrictions placed on its transferability. Loans and Leases Fair values of loans and leases, excluding loans held for sale, are estimated as follows: For variable rate loans that reprice frequently and with no significant change in credit risk, fair values are based on carrying values resulting in a Level 3 classification. Fair values for other 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. Deposits The fair values disclosed for demand deposits (e.g., interest and noninterest bearing checking, passbook savings, and 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 1 classification. 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. Other Borrowings The fair values of the Company’s long-term FHLB advances 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 2 classification.  Accrued Interest Receivable/Payable The carrying amounts of accrued interest approximate fair value resulting in a Level 1 , 2 or 3 classification, consistent with the asset or liability with which they are associated. Advances by Borrowers for Taxes and Insurance The carrying amount of advances by borrowers for taxes and insurance approximates fair value resulting in a Level 3 classification, consistent with the liability with which they are associated. Off-Balance-Sheet Instruments The fair value of off-balance-sheet items is not considered material.

Subordinated Debentures [Abstract]
Subordinated Debentures	 NOTE 12 – SUBORDINATED DEBENTURES In December 2003, Central Federal Capital Trust I, a trust formed by the Holding Company, closed a pooled private offering of 5,000 trust preferred securities with a liquidation amount of $1 per security. The Holding Company issued $5,155 of subordinated debentures to the trust in exchange for ownership of all of the common stock of the trust and the proceeds of the preferred securities sold by the trust . The Holding Company is not considered the primary beneficiary of this trust (variable interest entity); therefore, the trust is not consolidated in the Company’s financial statements, but rather the subordinated debentures are shown as a liability. The Holding Company’s investment in the common stock of the trust was $155 and is included in other assets. The Holding Company may redeem the subordinated debentures, in whole or in part, in a principal amount with integral multiples of $1 , on or after December 30, 2008 at 100% of the principal amount, plus accrued and unpaid interest. The subordinated debentures mature on December 30, 2033 . The subordinated debentures are also redeemable in whole or in part from time to time, upon the occurrence of specific events defined within the trust indenture. There are no required principal payments on the subordinated debentures over the next five years. The Holding Company has the option to defer interest payments on the subordinated debentures for a period not to exceed five consecutive years. The subordinated debentures have a variable rate of interest, reset quarterly, equal to the three-month London Interbank Offered Rate plus 2.85% , which was 4.54% at year-end 201 7 and 3.85% at year-end 201 6 .

Benefit Plans [Abstract]
Benefit Plans	 NOTE 13 – BENEFIT PLANS Multi-employer pension plan : CFBank participates in the Pentegra Defined Benefit Plan for Financial Institutions (the “ Pentegra DB Plan ” ), a multi-employer contributory trusteed pension plan. The retirement benefits to be provided by the plan were frozen as of June 30, 2003 and future employee participation in the plan was stopped. The plan was maintained for all eligible employees and the benefits were funded as accrued. The cost of funding was charged directly to operations. The unfunded liability under the Pentegra DB Plan at June 30, 201 7 totale d $36 an d at June 30, 201 6 was $53 . CFBank’s contributions for the plan years ending June 30, 201 7 and June 30, 201 6 , totaled $32 , a nd $42 , respectively. Contributions to the plan may vary from period to period due to the change in the plan's unfunded liability. The unfunded liability is primarily related to the change in plan assets and the change in plan liability from one year to the next. The change in plan assets is based on contributions deposited, benefits paid and the actual rate of return earned on those assets. The change in plan liability is based on demographic changes and changes in the interest rates used to determine plan liability. In the event the actual rate of return earned on plan assets declines, the value of the plan assets will decline. In the event the interest rates used to determine plan liability decrease, plan liability will increase. The combined effect of each change determines the change in the unfunded liability and the change in the employer contributions. The Pentegra DB Plan is a tax-qualified defined-benefit pension plan. The Pentegra DB Plan operates as a multi-employer plan for accounting purposes and as a multiple-employer plan under the Employee Retirement Income Security Act of 1974 and the Internal Revenue Code. There are no collective bargaining agreements in place that require contributions to the Pentegra DB Plan. The Pentegra DB Plan is a single plan under Internal Revenue Code Section 413(c) and, as a result, all of the assets stand behind all of the liabilities. Accordingly, under the Pentegra DB Plan contributions made by a participating employer may be used to provide benefits to participants of other participating employers. Funded status (market value of plan assets divided by funding target) based on valuation reports as of July 1, 201 7 and 201 6 was 96.54% and 94.90% , respectively. Total contributions made to the Pentegra DB Plan, as reported on Form 5500 of the Pentegra DB Plan, total ed $153,186 and $163,138 for the plan years ended June 30, 201 6 and June 30, 201 5 , respectively. CFBank’s contributions to the Pentegra DB Plan were not more than 5% of the total contributions to the Pentegra DB Plan. 401(k) Plan: The Company sponsors a 401(k) plan that allows employee contributions up to the maximum amount allowable under federal tax regulations, which are currently matched in an amount equal to 25% of the first 8% of the compensation contributed. Expense for 201 7 and 201 6 was $57 a nd $49 , respectively. Salary Continuation Agreement: In 2004, CFBank entered into a nonqualified salary continuation agreement with its former Chairman Emeritus. Benefits provided under the plan are unfunded, and payments are made by CFBank. Under the plan, CFBank pays him, or his beneficiary, a benefit of $25 annually for 20 years, beginning 6 months after his retirement date, which was February 28, 2008. The expense related to this plan totaled $10 and $10 in 201 7 and 201 6 , respectively. The accrual is included in accrued interest payable and other liabilities in the consolidated balance sheets and totaled $203 at year-e nd 201 7 and $218 at year-end 201 6 .  Life Insurance Benefits: CFBank has entered into agreements with certain employees, former employees and directors to provide life insurance benefits which are funded through life insurance policies purchased and owned by CFBank. The expense related to these benefits totaled ($19) and ($3) in 201 7 and 201 6 , respectively. The accrual for CFBank’s obligation under these agreements is included in accrued interest payable and other liabilities in the consolidated balance sheets and totaled $191 at year-end 201 7 and $210 at year-end 201 6 .

At December 31, 2016, the Company had a deferred tax asset recorded of approximately $2,600. At December 31, 2017 and December 31, 2016, the Company had no unrecognized tax benefits recorded. The Company is subject to U.S. federal income tax and is no longer subject to federal examination for years prior to 2014. On December 22, 2017, the United States enacted tax reform legislation through the Tax Cuts and Jobs Act, which significantly changes the existing U.S. tax laws, including a reduction in the corporate tax rate from 35% to 21%, as well as other changes. As a result of enactment of the legislation, the Company incurred additional one-time income tax expense of $979,000 during the fourth quarter of 2017, related to the remeasurement of the Company's deferred tax assets and liabilities. Our deferred tax assets are composed of U.S. net operating losses (“NOLs”), and other temporary book to tax differences. When determining the amount of deferred tax assets that are more-likely-than-not to be realized, and therefore recorded as a benefit, the Company conducts a regular assessment of all available information. This information includes, but is not limited to, taxable income in prior periods, projected future income and projected future reversals of deferred tax items. Based on these criteria, the Company determined as of December 31, 2017 that no valuation allowance was required against the net deferred tax asset. In 2012, a recapitalization program through the sale of $22,500 in common stock improved the capital levels of CFBank and provided working capital for the Holding Company. The result of the change in stock ownership associated with the stock offering, however, was that the Company incurred an ownership change within the guidelines of Section 382 of the Internal Revenue Code of 1986. At year-end 201 7 , the Company had net operating loss carryforwards of $23,059 , which expire at various dates from 2024 to 2033 . As a result of the ownership change, the Company's ability to utilize carryforwards that arose before the 2012 stock offering closed is limited to $163 per year. Due to this limitation, management determined it is more likely than not that $20,520 of net operating loss carryforwards will expire unutilized. As required by accounting standards, the Company reduced the carrying value of deferred tax assets, and the corresponding valuation allowance, by the $6,977 tax effect of this lost realizability. Federal income tax laws provided additional deductions, totaling $2,250 , for thrift bad debt reserves established before 1988. Accounting standards do not require a deferred tax liability to be recorded on this amount, which otherwise would have totaled $473 at year-end 201 7 . However, if CFBank were wholly or partially liquidated or otherwise ceases to be a bank, or if tax laws were to change, this amount would have to be recaptured and a tax liability recorded. Additionally, any distributions in excess of CFBank’s current or accumulated earnings and profits would reduce amounts allocated to its bad debt reserve and create a tax liability for CFBank. On December 22, 2017, the “Tax Cuts and Jobs Act” was enacted into law reducing the federal corporate tax rate to 21% , effective January 1, 2018. The Company conducted a revaluation of its existing deferred tax asset (DTA) to reflect the impact of the new tax rates, which resulted in the Company recording an additional tax expense in the fourth quarter of 2017 in the amount of $979 .

Stock-Based Compensation [Abstract]
Stock-Based Compensation	 NOTE 16 – STOCK-BASED COMPENSATION The Company has issued awards under three stock-based compensation plans ( collectively, the “Plans”), as described below. Total compensation cost that has been charged against income for those Plans totaled $246 and $122 for 201 7 and 201 6 , respectively. The total income tax benefit was $84 and $35 for 201 7 and 201 6 , respectively . The Plans are all stockholder-approved and authorize stock option grants and restricted stock awards to be made to directors, officers and employees. The 1999 Stock-Based Incentive Plan, which expired July 13, 2009, provided 38,778 shares of common stock for stock option grants and 15,511 shares of common stock for restricted stock awards. The 2003 Equity Compensation Plan (the “2003 Plan”), as amended and restated, provided an aggregate of 100,000 shares for stock option grants and restricted stock awards, of which up to 30,000 shares could be awarded in the form of restricted stock awards. The 2009 Equity Compensation Plan (the “2009 Plan”), which was approved by stockholders on May 21, 2009, replaced the 2003 Plan and provided for 200,000 shares, plus any remaining shares available to grant or that are later forfeited or expire under the 2003 Plan, to be made available to be issued as stock option grants, stock appreciation rights or restricted stock awards. On May 16, 2013, the Company’s stockholders approved the First Amendment to the 2009 Plan to increase the number of shares of common stock reserved for stock option grants and restricted stock awards thereunder to 1,500,000 . Stock Options: The Plans permit the grant of stock options to directors, officers and employees of the Holding Company and CFBank. Option awards are granted with an exercise price equal to the market price of the Company’s common stock on the date of grant, generally have vesting periods ranging from one to three years, and are exercisable for ten years from the date of grant. Unvested stock options immediately vest upon a change of control. 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. 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 stock options granted or exercised during the years ended December 31, 201 7 and December 31, 201 6 . A summary of stock option activity in the Plans for 201 7 follows:    Shares Weighted Average Exercise Price Weighted Average Remaining Contractual Term (Years) Intrinsic Value  Outstanding at beginning of year 542,746 $ 1.46  Expired (300) 36.75  Cancelled or forfeited (3,190) 1.70  Outstanding at end of period 539,256 $ 1.44 5.4 $ 731,080   Expected to vest - $ - - $ -   Exercisable at end of period 539,256 $ 1.44 5.4 $ 731,080  During the year ended December 31, 2017, there were 3, 190 stock options canceled or forfeited. Expense associated with unvested forfeited shares is reversed. As of December 31, 2017, all stock options granted under the Plans were vested.  Restricted Stock Awards: The Plans also permit the grant of restricted stock awards to directors, officers and employees. Compensation is recognized over the vesting period of the awards based on the fair value of the stock at grant date. The fair value of the stock is determined using the closing share price on the date of grant and shares generally have vesting periods of one to three years. There were 215,500 shares of restricted stock issued in 201 7 and 292,000 shares of restricted stock issued in 201 6 . A summary of changes in the Company’s nonvested restricted shares for the year follows:     Nonvested Shares Shares Weighted Average Grant-Date Fair Value  Nonvested at January 1, 2017 425,666 $ 1.56  Granted 215,500 2.56  Vested (157,172) 1.53  Forfeited (19,333) 1.58  Nonvested at December 31, 2017 464,661 $ 2.03  As of December 31, 201 7 and 201 6 , the unrecognized compensation cost related to nonvested shares granted under the Plans was $918 and $642 , respectively. There were 157,172 shares that vested during the year ended December 31, 201 7 . There were 347,115 shares remaining available for stock option grants and restricted stock awards under the 2009 Plan at December 31, 201 7 .

Preferred Stock	 NOTE 17 – PREFERRED STOCK Series B Preferred Stock: Commencing in April 2014, the Company conducted a private placement of up to 480,000 shares of its 6.25% Non-Cumulative Convertible Perpetual Preferred Stock, Series B (“Series B Preferred Stock”) for an offering price of $25.00 per share (the “Private Placement”). Pursuant to the Private Placement, the Company sold an aggregate of 480,000 shares of Series B Preferred Stock on May 12, 2014 and July 15, 2014, for an aggregate offering price of $12,000 . After payment of approximately $482 in placement fees and approximately $149 of other offering expenses, the Company’s net proceeds from its sale of the 480,000 shares of Series B Preferred Stock in the Private Placement were approximately $11,369 . For each share of Series B Preferred Stock sold in the Private Placement, the Company also issued, at no additional charge, a Warrant to purchase common stock of the Company. See Note 18-Common Stock Warrants for additional information. Conversion of Series B Preferred Stock to Common Stock: On September 29, 2017, the Company announced the conversion of its Series B Preferred Stock into shares of Common Stock of the Company . The conversion was effective October 6, 2017, and resulted in the conversion of all 480,000 of the Company’s issued and outstanding shares of Series B Preferred Stock into approximately 6,857,143 shares of Common Stock. T he conversion of the Series B Preferred Stock result ed in the elimination of the non-cumulative preferred dividend payments on the Series B Preferred Stock beginning with the 4th quarter of 2017 . The preferred dividends, in the aggregate amount of approximately $187,500 quarterly, or approximately $750,000 annually, will not be payable by the Company going forward.

Regulatory Capital Matters

Regulatory Capital Matters [Abstract]
Regulatory Capital Matters	 NOTE 19 – REGULATORY CAPITAL MATTERS CFBank is subject to regulatory capital requirements administered by federal banking agencies. Prompt corrective action regulations involve quantitative measures of assets, liabilities, and certain off balance-sheet items calculated under regulatory accounting practices. Capital amounts and classifications are also subject to qualitative judgments by regulators. Failure to meet capital requirements can initiate regulatory action. Prompt corrective action regulations provide five classifications for banking organizations: well capitalized, adequately capitalized, undercapitalized, significantly undercapitalized, and critically undercapitalized, although these terms are not used to represent overall financial condition. If a banking organization is classified as adequately capitalized, regulatory approval is required to accept brokered deposits. If a banking organization is classified as undercapitalized, capital distributions are limited, as is asset growth and expansion, and capital restoration plans are required. I n July 2013, the Holding Company’s primary federal regulator, the FRB, published final rules (the “Basel III Capital Rules”) establishing a new comprehensive capital framework for U.S. banking organizations. The rules implement the Basel Committee's December 2010 framework known as “Basel III” for strengthening international capital standards as well as certain provisions of the Dodd-Frank Act. The Basel III Capital Rules provide higher capital requirements and more restrictive leverage and liquidity ratios than those previously in place. In addition, in order to avoid limitations on capital distributions, such as dividend payments and certain bonus payments to executive officers, the Basel III Capital Rules require insured financial institutions to hold a capital conservation buffer of common equity tier 1 capital above the minimum risk-based capital requirements. The capital conservation buffer will be phased in over time, becoming fully effective on January 1, 2019, and will consist of an additional amount of common equity equal to 2.5% of risk-weighted assets. The Basel III Capital Rules revise the regulatory agencies' prompt corrective action framework by incorporating the new regulatory capital minimums and updating the definition of common equity. The Basel III Capital Rules became effective for the Company on January 1, 2015, and will be fully phased in by January 1, 2019. Quantitative measures established by the Basel III Capital Rules to ensure capital adequacy require the maintenance of minimum amounts and ratios of Common Equity Tier 1 capital, Tier 1 capital and Total capital, as defined in the regulations, to risk-weighted assets, and of Tier 1 capital to adjusted quarterly average assets (“Leverage Ratio”). CFBank’s implementation of the new rules on January 1, 2015 did not have a material impact on our capital needs or classification . When fully phased in on January 1, 2019, the Basel III Capital Rules will require CFBank to maintain: 1) a minimum ratio of Common Equity Tier 1 capital to risk-weighted assets of 4.5%, plus a 2.5% “capital conservation buffer” (resulting in a minimum ratio of Common Equity Tier 1 capital to risk-weighted assets of 7.0% upon full implementation); 2) a minimum ratio of Tier 1 capital to risk-weighted assets of 6.0%, plus the capital conservation buffer (resulting in a minimum Tier 1 capital ratio of 8.5% upon full implementation); 3) a minimum ratio of Total capital to risk-weighted assets of 8.0%, plus the capital conservation buffer (resulting in a minimum Total capital ratio of 10.5% upon full implementation); and 4) a minimum Leverage Ratio of 4.0% The implementation of the capital conservation buffer began on January 1, 2016 at the 0.625% level and will be phased in over a four-year period increasing by increments of that amount on each subsequent January 1 until it reaches 2.5% on January 1, 2019. The capital conservation buffer is currently 1.875%. The capital conservation buffer is designed to absorb losses during periods of economic stress. Failure to maintain the minimum Common Equity Tier 1 capital ratio plus the capital conservation buffer will result in potential restrictions on a banking institution’s ability to pay dividends, repurchase stock and/or pay discretionary compensation to its employees .  T he following tables present actual and required capital ratios as of December 31 , 2017 and December 31, 2016 for CFBank under the Basel III Capital Rules. The minimum required capital amounts presented include the minimum required capital levels as of December 31 , 2017, based on the phase-in provisions of the Basel III Capital Rules and the minimum required capital levels as of January 1, 2019 when the Basel III Capital Rules have been fully phased-in. Capital levels required to be considered well capitalized are based upon prompt corrective action regulations, as amended to reflect the changes under the Basel III Capital Rules .

Previously, the Qualified Thrift Lender test required CFBank to maintain at least 65% of assets in housing-related finance and other specified areas. CFBank converted from a mutual to a stock institution in 1998, and a “liquidation account” was established with an initial balance of $14,300 , which was the net worth reported in the conversion prospectus. The liquidation account represents a calculated amount for the purposes described below, and it does not represent actual funds included in the consolidated financial statements of the Company. Eligible depositors who have maintained their accounts, less annual reductions to the extent they have reduced their deposits, would be entitled to a priority distribution from this account if CFBank liquidated and its assets exceeded its liabilities. Dividends may not reduce CFBank’s stockholder’s equity below the required liquidation account balance.  Dividend Restrictions: The Holding Company’s principal source of funds for dividend payments is dividends received from CFBank. Banking regulations limit the amount of dividends that may be paid without prior approval of regulatory agencies. Under these regulations, the amount of dividends that may be paid in any calendar year is limited to the current year’s net profits, combined with the retained net profits of the preceding two years, subject to the capital requirements described above. Any future dividend payments by CFBank to the Holding Company would be based on future earnings and, if necessary, regulatory approval. The Holding Company’s ability to pay dividends on its stock is also conditioned upon the payment, on a current basis, of quarterly interest payments on the subordinated debentures underlying the Company’s trust preferred securities. Additionally, so long as the Company’s Series B Preferred Stock remains outstanding, the Holding Company is prohibited from paying dividends (other than dividends payable solely in shares) on the Company’s common stock for the then-current dividend period, unless full dividends on the Series B Preferred Stock have been paid or set aside for payment. Effective October 6, 2017, the Company caused the conversion of all of its outstanding shares of Series B Preferred Stock into shares of Common Stock of the Company. The conversion of the Series B Preferred Stock results in the elimination of the non-cumulative preferred dividend payments on the Series B Preferred Stock beginning with the 4th quarter of 2017. Additionally CFBank does not intend to make distributions to the Holding Company that would result in a recapture of any portion of its thrift bad debt reserve as discussed in Note 14-Income taxes .

Derivative Instruments [Abstract]
Derivative Instruments	 NOTE 20 – DERIVATIVE INSTRUMENTS Interest-rate swaps: CFBank utilizes interest-rate swaps as part of its asset liability management strategy to help manage its interest rate risk position and does not use derivatives for trading purposes. The notional amount of the interest-rate swaps does not represent amounts exchanged by the parties. The amount exchanged is determined by reference to the notional amount and the other terms of the individual interest-rate swap agreements. CFBank was party to interest-rate swaps with a combined notional amount of $2,185 at December 31, 201 7 and $2,280 at December 31, 201 6 . The objective of the interest-rate swaps is to protect the related fixed - rate commercial real estate loans from changes in fair value due to changes in interest rates. CFBank has a program whereby it lends to its borrowers at a fixed - rate with the loan agreement containing a two-way yield maintenance provision, which will be invoked in the event of prepayment of the loan, and is expected to exactly offset the fair value of unwinding the swap. The yield maintenance provision represents an embedded derivative which is bifurcated from the host loan contract and, as such, the swaps and embedded derivatives are not designated as hedges. Accordingly, both instruments are carried at fair value and changes in fair value are reported in current period earnings. CFBank currently does not have any derivatives designated as hedges. Contingent Features: The counterparty to CFBank’s interest-rate swaps is exposed to credit risk whenever the interest-rate swaps are in a liability position. At December 31, 201 7 , CFBank had $645 in securities and cash pledged as collateral for these derivatives. Should the liability increase beyond the collateral value, CFBank will be required to pledge additional collateral. Additionally, CFBank’s interest-rate swap instruments contain provisions that require CFBank to remain well capitalized under regulatory capital standards. The interest-rate swaps may be called by the counterparty if CFBank fails to maintain well-capitalized status under regulatory capital standards. As of December 31, 2017, CFBank was well-capitalized under regulatory capital standards.  Summary information about the derivative instruments is as follows:   2017 2016  Notional amount $ 2,185 $ 2,280  Weighted average pay rate on interest-rate swaps 3.75% 3.74%  Weighted average receive rate on interest-rate swaps 1.52% 0.75%  Weighted average maturity (years) 2.1 3.1  Fair value of interest-rate swaps $ (56) $ (122)  Fair value of yield maintenance provisions $ 56 $ 122  The fair value of the yield maintenance provisions and interest-rate swaps is recorded in other assets and other liabilities, respectively, in the consolidated balance sheet. Changes in the fair value of the yield maintenance provisions and interest-rate swaps are reported currently in earnings, as other noninterest income in the consolidated statements of income . There were no net gains or losses recognized in earnings related to yield maintenance provisions and interest-rate swaps in 201 7 or 201 6 . Mortgage banking derivatives: Commitments to fund certain mortgage loans (interest rate locks) to be sold into the secondary market are considered derivatives. These mortgage banking derivatives are not designated in hedge relationships. The Company had approximately $2,390 and $2,164 of interest rate lock commitments related to residential mortgage loans at December 31, 201 7 and 201 6 , respectively. The fair value of these mortgage banking derivatives was reflected by a derivative asset of $11 and $8 a t December 31, 201 7 and 201 6 , respectively, which was included in other assets in the consolidated balance sheet. Fair values were estimated based on anticipated gains on the sale of the underlying loans. Changes in the fair values of these mortgage banking derivatives are included in net gains on sales of loans. Net gains (losses) recognized in earnings related to these mortgage banking derivatives totaled $5 and 7 in 201 7 and 201 6 , respectively .

Loan Commitments And Other Related Activities [Abstract]
Loan Commitments And Other Related Activities	 NOTE 21 – LOAN COMMITMENTS AND OTHER RELATED ACTIVITIES Some financial instruments, such as loan commitments, credit lines, letters of credit and overdraft pro tection, are issued to meet customer financing needs. These are agreements to provide credit or to support the credit of others, as long as conditions established in the contract are met, and usually have expiration dates. Commitments may expire without being used. Off ‑balance-sheet risk to credit loss exists up to the face amount of these instruments, although material losses are not anticipated. The same credit policies are used to make such commitments as are used for loans, including obtaining collateral at exercise of the commitment. The contractual amounts of financial instruments with off-balance-sheet risk at year end were as follows :    2017 2016  Fixed Rate Variable Rate Fixed Rate Variable Rate  Commitments to make loans $ 15,856 $ 21,716 $ 21,335 $ 22,171  Unused lines of credit $ 8,068 $ 38,760 $ 3,714 $ 29,621  Standby letters of credit $ 1,115 $ - $ 991 $ -  Commitments to make loans are generally made for periods of 60 days or less, except for construction loan commitments, which are typically for a period of one year, and loans under a specific drawdown schedule, which are based on the individual contract s. The fixed-rate loan commitments had interest rates ranging from 2.00% to 5.88% and maturities ranging from 21 months to 30 years at December 31, 2017. The fixed-rate loan commitments had interest rates ranging from 1.75% to 6.50% and maturities ranging fro m 2 months to 30 years at December 31, 201 6 .

Summary of Significant Accoun36

Summary of Significant Accounting Policies (Policy)	12 Months Ended
	Dec. 31, 2017
Summary Of Significant Accounting Policies [Abstract]
Nature of Operations and Principles of Consolidation	Nature of Operations and Principles of Consolidation : The consolidated financial statements include Central Federal Corporation (the “Holding Company”) and its wholly-owned subsidiary, CFBank , National Association (“CFBank”) . On December 1, 2016, CFBank converted from a federal savings institution to a national bank. The Holding Company and CFBank are sometimes collectively referred to her e in as the “Company”. Intercompany transactions and balances are eliminated in consolidation. CFBank provides financial services through its five full-service banking offices in Worthington, Fairlawn, Glendale, Calcutta, and Wellsville, Ohio, and through its agency office in Woodmere, Ohio. Its primary deposit products are commercial and retail checking, savings, money market and term certificate accounts. Its primary lending products are commercial and commercial real estate, residential mortgages and installment loans. There are no significant concentrations of loans to any one industry or customer segment. However, our customers’ ability to repay their loans is dependent on general economic conditions and the real estate values in their geographic areas.
Use of Estimates	Use of Estimates : To prepare financial statements in conformity with U.S. generally accepted accounting principles (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 actual results could differ. The allowance for loan and lease losses (ALLL), deferred tax assets and fair values of financial instruments are particularly subject to change.
Cash Flows	Cash Flows : Cash and cash equivalents include cash, deposits with other financial institutions with maturities fewer than 90 days and federal funds sold. Net cash flows are reported for customer loan and deposit transactions, interest-bearing deposits in other financial institutions and borrowings with original maturities under 90 days.
Interest-Bearing Deposits in Other Financial Institutions	Interest-Bearing Deposits in Other Financial Institutions : Interest ‑bearing deposits in other financial institutions mature in April, 2019 and are carried at cost. As of December 31, 2017 and December 31, 201 6 , there was $100 in an interest-bearing deposit in other financial institutions.
Securities	Securities : Debt securities are classified as available for sale when they might be sold before maturity. Equity securities with readily determinable fair values are classified as available for sale. Securities available for sale are carried at fair value, with unrealized holding gains and losses reported in other comprehensive income. Interest income includes amortization of purchase premium or accretion of discount. Premiums and discounts on securities are amortized or accreted on the level-yield method, except for mortgage-backed securities and collateralized mortgage obligations where prepayments are anticipated based on industry payment trends. Gains and losses on sales are recorded on the trade date and determined using the specific identification method. Management evaluates securities for other-than-temporary impairment (OTTI) at least on a quarterly basis, and more frequently when economic or market conditions warrant such an evaluation. For securities in an unrealized loss position, management considers the extent and duration of the unrealized loss and the financial condition and near-term prospects of the issuer. Management also assesses whether it intends to sell, or will more likely than not be required to sell, a security in an unrealized loss position before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the entire difference between amortized cost and fair value is recognized as impairment through earnings. For debt securities that do not meet the aforementioned criteria, the amount of impairment is split into two components as follows: 1) OTTI related to credit loss, which must be recognized in the income statement and 2) OTTI related to other factors, which is recognized in other comprehensive income. The credit loss is defined as the difference between the present value of the cash flows expected to be collected and the amortized cost basis. For equity securities, the entire amount of impairment is recognized through earnings.
Loans Held for Sale	Loans Held for Sale : Mortgage loans originated and intended for sale in the secondary market are carried at fair value, as determined by outstanding commitments from investors. Mortgage loans held for sale are generally sold with servicing rights released. The carrying value of mortgage loans sold is reduced by the amount allocated to the servicing rights when mortgage loans held for sale are sold with servicing rights retained. Loans originated as construction loans, that were subsequently transferred to held for sale, are carried at the lower of cost or market. Gains and losses on sales of mortgage loans are based on the difference between the selling price and the carrying value of the related loan sold. 
Loans And Lease	Loans and Leases : Loans and leases that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at the principal balance outstanding, adjusted for purchase premiums and discounts, deferred loan fees and costs and an allowance for loan and lease losses (ALLL). Interest income is accrued on the unpaid principal balance. Loan origination fees, net of certain direct origination costs, are deferred and recognized in interest income using the level ‑yield method without anticipating prepayments. The accrual of interest income on all classes of loans, except other consumer loans, is discontinued and the loan is placed on nonaccrual status at the time the loan is 90 days delinquent unless the loan is well-secured and in process of collection. Other consumer loans are typically charged off no later than 90 days past due. Past due status is based on the contractual terms of the loan for all classes of loans. In all cases, loans are placed on nonaccrual or charged-off at an earlier date if collection of principal or interest is considered doubtful. Nonaccrual loans and loans past due 90 days still on accrual include both smaller balance homogeneous loans that are collectively evaluated for impairment and individually classified impaired loans. Commercial, multi-family residential real estate loans and commercial real estate loans placed on nonaccrual status are individually classified as impaired loans. All interest accrued but not received for each loan placed on nonaccrual is reversed against interest income in the period in which it is placed in a nonaccrual status. Interest received on such loans is accounted for on the cash-basis or cost ‑recovery method, until qualifying for return to accrual status. Loans are considered for return to accrual status provided all the principal and interest amounts that are contractually due are brought current, there is a current and well documented credit analysis, there is reasonable assurance of repayment of principal and interest, and the customer has demonstrated sustained, amortizing payment performance of at least six months.
Concentration of Credit Risk	Concentration of Credit Risk : Most of the Company’s primary business activity is with customers located within the Ohio counties of Franklin, Hamilton, Cuyahoga , Summit , Columbiana and contiguous counties. Therefore, the Company’s exposure to credit risk can be affected by changes in the economies within these counties. Although these counties are the Company’s primary market area for loans, the Company originates residential and commercial real estate loans throughout the United States.
Allowance for Loan And Lease Losses (ALLL)	Allowance for Loan and Lease Losses (ALLL) : The ALLL is a valuation allowance for probable incurred credit losses. Loan losses are charged against the allowance when management believes the uncollectibility of a loan balance is confirmed. Subsequent recoveries, if any, are credited to the allowance. Management estimates the allowance balance required using past loan loss experience, the nature and volume of the portfolio, information about specific borrower situations and estimated collateral values, economic conditions, and other factors. Allocations of the allowance may be made for specific loans, but the entire allowance is available for any loan that, in management’s judgment, should be charged off. The allowance consists of specific and general components. The specific component relates to loans that are individually classified as impaired. A loan is impaired when, based on current information and events, it is probable that CFBank will be unable to collect all amounts due according to the contractual terms of the loan agreement. Loans within any loan class for which the terms have been modified resulting in a concession, and for which the borrower is experiencing financial difficulties, are considered troubled debt restructurings (TDRs) and classified as impaired. Factors considered by management in determining impairment for all loan classes include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record and the amount of the shortfall in relation to the principal and interest owed. All loans within the commercial, multi-family residential and commercial real estate segments, regardless of size, and loans of all other classes with balances over $250 are individually evaluated for impairment when they are 90 days past due, or earlier than 90 days past due if information regarding the payment capacity of the borrower indicates that payment in full according to the loan terms is doubtful. If a loan is impaired, a portion of the allowance is allocated so that the loan is reported, net, at the present value of estimated future cash flows using the loan’s existing rate, or at the fair value of collateral, less costs to sell, if repayment is expected solely from the collateral. Large groups of smaller balance homogeneous loans, such as consumer and single-family residential real estate loans, are collectively evaluated for impairment, and accordingly, they are not separately identified for impairment disclosures.  TDRs of all classes of loans are separately identified for impairment disclosures and are measured at the present value of estimated future cash flows using each loan’s effective rate at inception. If a TDR is considered to be a collateral dependent loan, the loan is reported, net, at the fair value of the collateral. If the payment of the loan is dependent on the sale of the collateral, then costs to liquidate the collateral are included when determining the impairment. For TDRs that subsequently default, the amount of reserve is determined in accordance with the accounting policy for the ALLL. Interest income on all classes of impaired loans that are on nonaccrual status is recognized in accordance with the accounting policy for nonaccrual loans. Cash receipts on all classes of impaired loans that are on nonaccrual status are generally applied to the principal balance outstanding. Interest income on all classes of impaired loans that are not on nonaccrual status is recognized on the accrual method. TDRs may be classified as accruing if the borrower has been current for a period of at least six months with respect to loan payments and management expects that the borrower will be able to continue to make payments in accordance with the terms of the restructured note. The general reserve component covers non ‑impaired loans of all classes and is based on historical loss experience adjusted for current factors. The historical loss experience is determined by loan class and is based on the actual loss history experienced by the Company over a three-year period. The general component is calculated based on CFBank’s loan balances and actual historical three-year historical loss rates. For loans with little or no actual loss experience, industry estimates are used based on loan segment. This loss experience is supplemented with other economic and judgmental factors based on the risks present for each loan class. These economic and judgmental factors include consideration of the following: levels of and trends in delinquencies and impaired loans; levels of and trends in charge-offs and recoveries; trends in volume and terms of loans; effects of any changes in risk selection and underwriting standards; other changes in lending policies, procedures, and practices; experience, ability, and depth of lending management and other relevant staff; national and local economic trends and conditions; industry conditions; and effects of changes in credit concentrations. The following portfolio segments have been identified: commercial loans ; single-family residential real estate loans; multi-family residential real estate loans; commercial real estate loans; construction loans; home equity lines of credit; and other consumer loans. A description of each segment of the loan portfolio, along with the risk characteristics of each segment , is included below . Commercial loans: Commercial loans include loans to businesses generally located within our primary market area. Those loans are generally secured by business equipment, inventory, accounts receivable and other business assets. In underwriting commercial loans, we consider the net operating income of the borrower , the debt service ratio and the financial strength, expertise and credit history of the business owners and/or guarantors. Because payments on commercial loans are dependent on successful operation of the business enterprise, repayment of such loans may be subject to a greater extent to adverse conditions in the economy. We seek to mitigate these risks through underwriting policies which require such loans to be qualified at origination on the basis of the borrower ’s financial performance and the financial strength of the business owners and/or guarantors. Single-family residential real estate loans: Single-family residential real estate loans include permanent conventional mortgage loans secured by single-family residences located within and outside of our primary market area. Credit approval for single-family residential real estate loans requires demonstration of sufficient income to repay the principal and interest and the real estate taxes and insurance, stability of employment and an established credit record. Our policy is to originate single-family residential real estate loans for portfolio in amounts up to 85% of the lower of the appraised value or the purchase price of the property securing the loan, without requiring private mortgage insurance. Loans in excess of 85% of the lower of the appraised value or purchase price of the property securing the loan require private mortgage insurance. CFBank has not engaged in subprime lending or used option adjustable-rate mortgage products. Multi-family residential real estate loans: Multi-family residential real estate loans include loans secured by apartment buildings, condominiums and multi-family residential houses generally located within our primary market area. Underwriting policies provide that multi-family residential real estate loans may be made in amounts up to 85% of the lower of the appraised value or purchase price of the property. In underwriting multi-family residential real estate loans, we consider the appraised value and net operating income of the property, the debt service ratio and the property owner’s and/or guarantor’s financial strength, expertise and credit history. We offer both fixed-rate and adjustable-rate loans. Fixed-rate loans are generally limited to three to five years, at which time they convert to adjustable-rate loans. Because payments on loans secured by multi-family residential properties are dependent on successful operation or management of the properties, repayment of multi-family residential real estate loans may be subject to a greater extent to adverse conditions in the real estate market or the economy. Adjustable-rate multi-family residential real estate loans generally pose credit risks not inherent in fixed-rate loans, primarily because as interest rates rise, the borrowers’ payments rise, increasing the potential for default. Additionally, adjustable-rate multi-family residential real estate loans generally do not contain periodic and lifetime caps on interest rate changes. We seek to minimize the additional risk presented by adjustable-rate multi-family residential real estate loans through underwriting criteria that require such loans to be qualified at origination with sufficient debt coverage ratios under increasing interest rate scenarios.  Commercial real estate loans: Commercial real estate loans include loans secured by owner occupied and non-owner occupied properties used for business purposes, such as manufacturing facilities, office buildings or retail facilities generally located within our primary market area. Underwriting policies provide that commercial real estate loans may be made in amounts up to 85% of the lower of the appraised value or purchase price of the property. In underwriting commercial real estate loans, we consider the appraised value and net operating income of the property, the debt service ratio and the property owner’s and/or guarantor’s financial strength, expertise and credit history. We offer both fixed and adjustable-rate loans. Fixed-rate loans are generally limited to three to five years, at which time they convert to adjustable-rate loans. Because payments on loans secured by commercial real estate properties are dependent on successful operation or management of the properties, repayment of commercial real estate loans may be subject to a greater extent to adverse conditions in the real estate market or the economy. Adjustable-rate commercial real estate loans generally pose credit risks not inherent in fixed-rate loans, primarily because as interest rates rise, the borrowers’ payments rise, increasing the potential for default. Additionally, adjustable-rate commercial real estate loans generally do not contain periodic and lifetime caps on interest rate changes. We seek to minimize the additional risk presented by adjustable-rate commercial real estate loans through underwriting criteria that require such loans to be qualified at origination with sufficient debt coverage ratios under increasing interest rate scenarios. Construction loans: Construction loans include loans to finance the construction of residential and commercial properties generally located within our primary market area. Construction loans are fixed-rate or adjustable-rate loans which may convert to permanent loans with maturities of up to 30 years. Our policies provide that construction loans may be made in amounts up to 80% of the appraised value of the property, and an independent appraisal of the property is required. Loan proceeds are disbursed in increments as construction progresses and as inspections warrant, and regular inspections are required to monitor the progress of construction. In underwriting construction loans, we consider the property owner’s and/or guarantor’s financial strength, expertise and credit history. Construction financing is considered to involve a higher degree of credit risk than long-term financing on improved, owner occupied real estate. Risk of loss on a construction loan is dependent largely upon the accuracy of the initial estimate of the property’s value at completion of construction or development compared to the estimated cost (including interest) of construction. If the estimate of value proves to be inaccurate, we may be confronted with a project, when completed, having a value which is insufficient to assure full repayment. We attempt to reduce such risks on construction loans through inspections of construction progress on the property and by requiring personal guarantees and reviewing current personal financial statements and tax returns, as well as other projects of the developer. Home equity lines of credit: Home equity lines of credit include both loans we originate for portfolio and purchased loans. We originate home equity lines of credit to customers generally within our primary market area. Home equity lines of credit are variable rate loans and the interest rate adjusts monthly at various margins above the prime rate of interest as disclosed in The Wall Street Journal. The margin is based on certain factors including the loan balance, value of collateral, election of auto-payment, and the borrower’s FICO® score. The amount of the line is based on the borrower’s credit, income and equity in the home. When combined with the balance of the prior mortgage liens, these lines generally may not exceed 89.9% of the appraised value of the property at the time of the loan commitment. The lines are secured by a subordinate lien on the underlying real estate and are, therefore, vulnerable to declines in property values in the geographic areas where the properties are located. Credit approval for home equity lines of credit requires income sufficient to repay principal and interest due, stability of employment, an established credit record and sufficient collateral. Collectability of home equity lines of credit are dependent on the borrower's continuing financial stability, and thus are more likely to be affected by adverse personal circumstances. We continue to monitor collateral values and borrower FICO® scores on both purchased and portfolio loans and, when the situation warrants, have frozen the lines of credit. Other consumer loans: Other consumer loans include closed-end home equity, home improvement, and auto and credit card loans to consumers generally located within our primary market area. Credit approval for other consumer loans requires income sufficient to repay principal and interest due, stability of employment, an established credit record and sufficient collateral for secured loans. Consumer loans typically have shorter terms and lower balances with higher yields as compared to real estate mortgage loans, but generally carry higher risks of default. Consumer loan collections are dependent on the borrower's continuing financial stability, and thus are more likely to be affected by adverse personal circumstances. CFBank’s charge-off policy for commercial loans, single-family residential real estate loans, multi-family residential real estate loans, commercial real estate loans, construction loans and home equity lines of credit requires management to record a specific reserve or charge-off as soon as it is apparent that the borrower is troubled and there is, or likely will be a collateral shortfall related to the estimated value of the collateral securing the loan. Other consumer loans are typically charged off no later than 90 days past due. 
Transfers of Financial Assets	Transfers of Financial Assets : Transfers of financial assets are accounted for as sales when control over the assets has been relinquished. Control over transferred assets is deemed to be surrendered when the assets have been isolated from the Company, the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity.
Foreclosed Assets	Foreclosed Assets : 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. If fair value declines subsequent to foreclosure, an adjustment is recorded through expense. Operating costs after acquisition are expensed.
Low Income Housing Tax Credits	Low Income Housing Tax Credits (LIHTC): The Company has invested in low income housing tax credits through a fund that assists corporations in investing in limited partnerships and limited liability companies that own, develop and operate low income residential rental properties for purposes of qualifying for the Housing Tax credit. These investments are accounted for under the proportional amortization method which recognizes the amortization of the investment in proportion to the tax credit and other tax benefits received.
Joint Ventures	Joint Ventures: The Holding Company contributed funds into a series of joint ventures (equity stake) for the purpose of allocating excess liquidity into higher earning assets while diversifying its revenue sources. The funding for the joint ventures is related to shorter term operating activities and is related to the development of single family real estate in the form of condominiums. Income is recognized based on a rate of return on the outstanding investment balance. As units are sold, the Holding Company receives an additional incentive payment, which is recognized as income. The balance outstanding in joint ventures at December 31, 2017 and December 31, 2016 was $325 and $325 , respectively. Income recognized on the joint ventures was $20 and $100 , respectively, for 2017 and 2016.
Premises and Equipment	Premises and Equipment : Land is carried at cost. Premises and equipment are stated at cost less accumulated depreciation. Buildings and related components are depreciated using the straight ‑line method with useful lives ranging from 3 to 40 years. Furniture, fixtures and equipment are depreciated using the straight ‑line method with useful lives ranging from 2 to 25 years. Leasehold improvements are depreciated straight-line over the shorter of the useful life or the lease term.
Federal Home Loan Bank (FHLB) Stock	Federal Home Loan Bank (FHLB) stock: CFBank is a member of the FHLB system. Members are required to own a certain amount of stock based on the level of borrowings and other factors, and may invest in additional amounts. FHLB stock is carried at cost, classified as a restricted security, and periodically evaluated for impairment based on ultimate recovery of par value. Both cash and stock dividends are reported as income.
Federal Reserve Bank (FRB) Stock	Federal Reserve Bank (F R B) stock: CFBank is a member of the FRB s ystem and is required to own a certain amount of stock. FRB stock is carried at cost, classified as a restricted security, and periodically evaluated for impairment based on ultimate recovery of par value. Both cash and stock dividends are reported as income.
Bank Owned Life Insurance	Bank Owned Life Insurance : CFBank purchased life insurance policies on certain directors and employees in 2002. Bank owned life insurance is recorded at the amount that can be realized under the insurance contract at the balance sheet date, which is the cash surrender value adjusted for other charges or other amounts due that are probable at settlement.
Loan Commitments and Related Financial Instruments	Loan Commitments and Related Financial Instruments : Financial instruments include off ‑balance-sheet credit instruments, such as commitments to make loans and commercial letters of credit, issued to meet customer financing needs. The face amount for these items represents the exposure to loss, before considering customer collateral or ability to repay. Such financial instruments are recorded when they are funded, and fees associated with origination are booked to non-interest income at the origination date.
Derivatives	Derivatives : Derivative financial instruments are recognized as assets or liabilities at fair value. The Company's derivatives consist mainly of interest rate swap agreements, which are used as part of its asset liability management program to help manage interest rate risk. The Company does not use derivatives for trading purposes. The derivative transactions are considered instruments with no hedging designation, otherwise known as stand-alone derivatives. Changes in the fair value of the derivatives are reported currently in earnings, as other noninterest income.
Mortgage Banking Derivatives	Mortgage Banking Derivatives : Commitments to fund mortgage loans to be sold into the secondary market, otherwise known as interest rate locks, are accounted for as free standing derivatives. Fair values of these mortgage derivatives are based on anticipated gains on the underlying loans. Changes in the fair values of these derivatives are included in net gains on sales of loans. 
Stock-Based Compensation	Stock-Based Compensation : Compensation cost is recognized for stock options and restricted stock awards issued to directors and employees, based on the fair value of these awards at the date of grant. A Black-Scholes model is utilized to estimate the fair value of stock options, while the market price of the Company’s common stock at the date of grant is used for restricted stock awards. Compensation cost is recognized over the required service period, generally defined as the vesting period. For awards with graded vesting, compensation cost is recognized on a straight-line basis over the required service period for each separately vesting portion of the award.
Income Taxes	Income Taxes : Income tax expense is the total of the current year income tax due or refundable and the change in deferred tax assets and liabilities. Deferred tax assets and liabilities are the expected future tax amounts for the temporary differences between carrying amounts and tax basis of assets and liabilities, computed using enacted tax rates. A tax position is recognized as a benefit only if it is “more likely than not” that the tax position would be sustained in a tax examination, with a tax examination being presumed to occur. The amount recognized is the largest amount of tax benefit that is greater than 50% likely of being realized on examination. For tax positions not meeting the “more likely than not” test, no tax benefit is recorded. The Company recognizes interest related to income tax matters as interest expense and penalties related to income tax matters as other noninterest expense.
Retirement Plans	Retirement Plans : Pension expense is the amount of annual contributions by the Company to the multi-employer contributory trusteed pension plan. Employee 401(k) and profit sharing plan expense is the amount of matching contributions. Supplemental retirement plan expense allocates the benefits over years of service.
Earnings Per Common Share	Earnings Per Common Share : Basic earnings per common share is net income available to common stockholders divided by the weighted average number of common shares outstanding during the period. All outstanding unvested share-based payment awards that contain rights to nonforfeitable dividends are considered participating securities for this calculation. Diluted earnings per common share includes the dilutive effect of additional potential common shares issuable under stock options.
Comprehensive Income (Loss)	Comprehensive Income (Loss) : Comprehensive income (loss) consists of net income (loss) and other comprehensive income (loss). Other comprehensive income (loss) includes unrealized gains and losses on securities available for sale, which are also recognized as a separate component of equity.
Loss Contingencies	Loss Contingencies : Loss contingencies, including claims and legal actions arising in the ordinary course of business, are recorded as liabilities when the likelihood of loss is probable and an amount or range of loss can be reasonably estimated. Management does not believe there are any such matters that will have a material effect on the financial statements. See Note 24 – Contingent Liabilities.
Restrictions on Cash	Restrictions on Cash : Cash on hand or on deposit with the Federal Reserve Bank (FRB) is required to meet regulatory reserve and clearing requirements. The reserve requirement at December 31, 2017 and December 31, 2016 was $718 and $267 , respectively . Cash on deposit with the FHLB includes $3,300 pledged as collateral for FHLB advances.
Equity	Equity : Treasury stock is carried at cost. The carrying value of preferred stock and the common stock warrant is based on allocation of issuance proceeds, net of issuance costs, in proportion to their relative fair values. Preferred stock is carried net of the discount established through the allocation of proceeds.
Dividend Restriction	Dividend Restriction : Banking regulations require us to maintain certain capital levels and may limit the dividends paid by CFBank to the Holding Company or by the Holding Company to stockholders. The ability of the Holding Company to pay dividends on its common stock and Series B Preferred Stock is generally dependent upon the receipt of dividends and other distributions from CFBank. The Holding Company is a legal entity that is separate and distinct from CFBank, which has no obligation to make any dividends or other funds available for the payment of dividends by the Holding Company. The Holding Company also is subject to various legal and regulatory policies and guidelines impacting the Holding Company’s ability to pay dividends on its stock . In addition, the Holding Company’s ability to pay dividends on its stock is conditioned upon the payment, on a current basis, of quarterly interest payments on the subordinated debentures underlying the Company’s trust preferred securities.  Effective October 6, 2017, all of its outstanding shares of Series B Preferred Stock were converted into shares of Common Stock of the Company. The conversion of the Series B Preferred Stock result ed in the elimination of the non-cumulative preferred dividend payments on the Series B Preferred Stock beginning with the 4th quarter of 2017.
Fair Value of Financial Instruments	Fair Value of Financial Instruments : Fair values of financial instruments are estimated using relevant market information and other assumptions, as more fully disclosed in Note 6 – Fair Value. Fair value estimates involve uncertainties and matters of significant judgment regarding interest rates, credit risk, prepayments, and other factors, especially in the absence of broad markets for particular items. Changes in assumptions or in market conditions could significantly affect these estimates.
Operating Segments	 Operating Segments : While management monitors and analyzes the revenue streams of the Company’s various products and services, the operations and financial performance is evaluated on a Company ‑wide basis. Operating results are not reviewed by senior management to make resource allocation or performance decisions. Accordingly, all of the financial service operations are considered by management to be aggregated in one reportable operating segment.
Reclassifications	Reclassifications: Some items in the prior year financial statements were reclassified to conform to the current presentation. Reclassifications had no effect on prior period net loss or stockholders’ equity.
Adoption of New Accounting Standards	Adoption of New Accounting Standards : In May 2014 the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2014-09, Revenue from Contracts with Customers (Topic 606) . The topic of Revenue Recognition had become broad with several other regulatory agencies issuing standards, which lacked cohesion. The new guidance establishes a “comprehensive framework” and “reduces the number of requirements to which an entity must consider in recognizing revenue” and yet provides improved disclosures to assist stakeholders reviewing financial statements. ASU No. 2014-09 provides that an entity should recognize revenue to depict the transfer of promised 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, and uncertainty of revenue and cash flows arising from contracts with customers. Guidance in ASU No. 2014-09 has been clarified by the following ASUs: · ASU No. 2016-08, “Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Revenue Gross versus Net)” · ASU No. 2016-10, “Revenue from Contracts with Customers (Topic 606): Identifying Performance Obligations and Licensing” · ASU No. 2016-12, “Revenue from Contracts with Customers (Topic 606): Narrow Scope Improvements and Practical Expedients” · ASU No. 2016-20, “Revenue from Contracts with Customers (Topic 606): Technical Corrections and Improvements to Topic 606” As extended by ASU No. 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date, ASU No. 2014-09 and the clarifying ASUs are effective for public companies for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period. Transitional guidance is included in the updates. Earlier adoption is permitted only as of annual reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period. While interest income is specifically out of scope of this standard, management has evaluated the revenue streams within “noninterest income” to assess the applicability of this standard. Based on our review, management has concluded that adoption of ASU No. 2015-14 will not have a significant effect on the Company’s consolidated financial statements, including disclosures. In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments—Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities . ASU 2016-01 amends the guidance in U.S. GAAP on the accounting for equity investments, financial liabilities under the fair value option and the presentations and disclosure requirements of financial instruments. ASU 2016-01 is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted for the accounting guidance on financial liabilities under the fair value option. The Company will adopt the methodologies prescribed by the ASU by the date required. Adoption of ASU No. 2016-01 did not have a significant effect on the Company’s consolidated financial statements. On February 25, 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) . Under the new ASU, lessees will recognize lease assets and liabilities on their balance sheets for all leases with terms of more than 12 months. The new lessee accounting model retains two types of leases, and is consistent with the lessee accounting model under existing GAAP. One type of lease (finance leases) will be accounted for in substantially the same manner as capital leases are accounted for today. The other type of lease (operating leases) will be accounted for (both in the income statement and statement of cash flows) in a manner consistent with today’s operating leases. Lessor accounting under the new standard is fundamentally consistent with existing GAAP. Lessees and lessors would be required to provide additional qualitative and quantitative disclosures to help financial statement users assess the amount, timing, and uncertainty of cash flows arising from leases. These disclosures are intended to supplement the amounts recorded in the financial statements so that users can understand more about the nature of an organization’s leasing activities. For public business entities, the final lease standard will be effective for fiscal years beginning after December 15, 2018 including interim periods within those fiscal years. Early application is permitted. The Company continues to evaluate the provision of the new lease standard and although we have not yet reasonably determined the estimated financial statement impact, due to the small number of lease agreements presently in effect for the Company, we believe the new guidance will not have a significant impact on the Company’s consolidated financial statements, including disclosures. In March 2016, the FASB issued ASU No. 2016-07, Investments—Equity Method and Joint Ventures (Topic 323): Simplifying the Transition to the Equity Method of Accounting . ASU No. 2016-07 affects all entities that have an investment that becomes qualified for the equity method of accounting as a result of an increase in the level of ownership interest or degree of influence. The amendments in this update eliminate the requirement that, when an investment qualifies for use of the equity method, an investor must adjust the investment, results of operations, and retained earnings retroactively on a step-by-step basis as if the equity method had been in effect during all previous periods that the investment had been held. ASU No. 2016-07 requires that the equity method investor add the cost of acquiring the additional interest in the investee to the current basis of the investor’s previously held interest and adopt the equity method of accounting as of the date the investment becomes qualified for equity method accounting. The amendments also require that an entity that has an available-for-sale equity security that becomes qualified for the equity method of accounting recognize through earnings the unrealized holding gain or loss in accumulated other comprehensive income at the date the investment becomes qualified for use of the equity method. The amendments in ASU No. 2016-07 are effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016. Adoption of ASU No. 2016-07 did not have a significant effect on the Company’s 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 No. 2016-09 affects all entities that issue share-based payment awards to their employees. The new guidance involves several aspects of the accounting for share-based payment transactions, including income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. Under ASU No. 2016-09, any excess tax benefits or tax deficiencies should be recognized as income tax expense or benefit in the income statement. Excess tax benefits are to be classified as an operating activity in the statement of cash flows. In accruing compensation cost, an entity can make an entity-wide accounting policy election to either estimate the number of awards that are expected to vest, as required under current guidance, or account for forfeitures when they occur. For an award to qualify for equity classification, an entity cannot partially settle the award in excess of the employer's maximum statutory withholding requirements. Such cash paid by an employer when directly withholding shares for tax withholding purposes should be classified as a financing activity in the statement of cash flows. The amendments in ASU No. 2016-09 are effective for public business entities for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2016. Adoption of ASU No. 2016-07 did not have a significant effect on the Company’s consolidated financial statements as of December 31, 2017. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments . Once effective, ASU No. 2016-13 will significantly change current guidance for recognizing impairment of financial instruments. Current guidance requires an "incurred loss" methodology for recognizing credit losses that delays recognition until it is probable a loss has been incurred. ASU No. 2016-13 replaces the incurred loss impairment methodology with a new methodology that reflects expected credit losses over the lives of the loans and requires consideration of a broader range of information to inform credit loss estimates. The ASU requires an organization to estimate all expected credit losses for financial assets measured at amortized cost, including loans and held-to-maturity debt securities, based on historical experience, current conditions, and reasonable and supportable forecasts. Additional disclosures are required. ASU No. 2016-13 also amends the accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration. Under the new guidance, entities will determine whether all or a portion of the unrealized loss on an available-for-sale debt security is a credit loss. Any credit loss will be recognized as an allowance for credit losses on available-for-sale debt securities rather than as a direct reduction of the amortized cost basis of the investment, as is currently required. As a result, entities will recognize improvements to estimated credit losses on available-for-sale debt securities immediately in earnings rather than as interest income over time, as currently required. ASU No. 2016-13 eliminates the current accounting model for purchased credit impaired loans and debt securities. Instead, purchased financial assets with credit deterioration will be recorded gross of estimated credit losses as of the date of acquisition and the estimated credit losses amounts will be added to the allowance for credit losses. Thereafter, entities will account for additional impairment of such purchased assets using the models listed above. ASU No. 2016-13 will take effect for U.S. Securities and Exchange Commission (SEC) filers for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early application will be permitted for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. While the Company generally expects that the implementation of ASU 2016-13 has the potential to increase its allowance for loan losses balance, the Company is continuing to evaluate the potential impact on the Company’s financial statements and disclosures. Management is currently assessing any additional data and system requirements necessary for adoption. At this time, the estimated financial statement, including disclosures, impact cannot be reasonably determined. In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows: Classification of Certain Cash Receipts and Cash Payments which may change how an entity classifies certain cash receipts and cash payments on its statement of cash flows to reduce diversity in practice. The update also provides guidance on when an entity should separate cash flows and classify them into more than one class and when an entity should classify the aggregate of those cash flows into a single class based on the predominance principle. The guidance in this ASU will become effective for interim and annual reporting periods beginning after December 15, 2017, with early adoption permitted. Management has reviewed the applicability of this ASU and has concluded that this will not have a material impact on its consolidated financial statements. The FASB has issued ASU 2017-08, Receivables—Nonrefundable Fees and Other Costs (Subtopic 310-20), Premium Amortization on Purchased Callable Debt Securities . The ASU shortens the amortization period for certain callable debt securities held at a premium to the earliest call date. Under current GAAP, entities normally amortize the premium as an adjustment of yield over the contractual life of the instrument. Stakeholders have expressed concerns with the current approach on the basis that current GAAP excludes certain callable debt securities from consideration of early repayment of principal even if the holder is certain that the call will be exercised. As a result, upon the exercise of a call on a callable debt security held at a premium, the unamortized premium is recorded as a loss in earnings. Further, there is diversity in practice (1) in the amortization period for premiums of callable debt securities, and (2) in how the potential for exercise of a call is factored into current impairment assessments. Another issue is that the practice in the United States is to quote, price, and trade callable debt securities assuming a model that incorporates consideration of calls (also referred to as “yield-to-worst” pricing). The ASU shortens the amortization period for certain callable debt securities held at a premium and requires the premium to be amortized to the earliest call date. However, the amendments do not require an accounting change for securities held at a discount; the discount continues to be amortized to maturity. The amendments are effective for public business entities for annual periods beginning after December 15, 2018, including interim periods within those annual periods. Early adoption is permitted. The Company has decided to adopt this ASU early and adoption did not have a material impact the Company’s consolidated financial statements as there were no callable debt securities held at a premium at the date of adoption. The FASB has issued ASU No. 2017-09, Compensation—Stock Compensation (Topic 718): Scope of Modification Accounting . ASU 2017-09 applies to entities that change the terms or conditions of a share-based payment award. The FASB adopted ASU 2017-09 to provide clarity and reduce diversity in practice as well as cost and complexity when applying the guidance in Topic 718, Compensation—Stock Compensation , to the modification of the terms and conditions of a share-based payment award. The amendments are effective for all entities for annual periods, and interim periods within those annual periods, beginning after December 15, 2017. Early adoption is permitted, including adoption in any interim period for: (a) public business entities for reporting periods for which financial statements have not yet been issued, and (b) all other entities for reporting periods for which financial statements have not yet been made available for issuance. The amendments should be applied prospectively to an award modified on or after the adoption date. Adoption of ASU No. 2017-09 is not expected to have a significant impact on the Company’s consolidated financial statements. The FASB has issued ASU No. 2017-12, Derivatives and Hedging (Topic 815) : Targeted Improvements to Accounting for Hedging Activities. The new standard is intended to improve and simplify accounting rules around hedge accounting. The new standard refines and expands hedge accounting for both financial (e.g., interest rate) and commodity risks. Its provisions create more transparency around how economic results are presented, both on the face of the financial statements and in the footnotes, for investors and analysts. The new standard takes effect for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018, for public companies and for fiscal years beginning after December 15, 2019 (and interim periods for fiscal years beginning after December 15, 2020), for private companies. Early adoption is permitted in any interim period or fiscal years before the effective date of the standard. Adoption of ASU No. 2017-12 is not expected to have a significant impact on the Company’s consolidated financial statements. The FASB issued ASU No. 2018-02, Income Statement—Reporting Comprehensive Income (Topic 220)—Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income . The ASU provides financial statement preparers with an option to reclassify stranded tax effects within AOCI to retained earnings in each period in which the effect of the change in the U.S. federal corporate income tax rate in the Tax Cuts and Jobs Act (or portion thereof) is recorded. The ASU requires financial statement preparers to disclose: · A description of the accounting policy for releasing income tax effects from AOCI; · Whether they elect to reclassify the stranded income tax effects from the Tax Cuts and Jobs Act; and · Information about the other income tax effects that are reclassified. The amendments affect any organization that is required to apply the provisions of Topic 220, Income Statement—Reporting Comprehensive Income , and has items of other comprehensive income for which the related tax effects are presented in other comprehensive income as required by GAAP. The amendments are effective for all organizations for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption is permitted. Adoption of ASU N o . 2018.-02 is not expected to have a material impact on the Company’s consolidated financial statements
