Summary of Significant Accounting Policies
Nature of Operations and Principles of Consolidation	Nature of Operations and Principles of Consolidation Broadway Financial Corporation (the "Company") is a Delaware corporation primarily engaged in the savings and loan business through its wholly owned subsidiary, Broadway Federal Bank, f.s.b. (the "Bank"). The Bank's business is that of a financial intermediary and consists primarily of attracting deposits from the general public and using such deposits, together with borrowings and other funds, to make mortgage loans secured by residential and commercial real estate located in Southern California. At December 31, 2016, the Bank operated two retail-banking offices in Los Angeles, California and one in the nearby city of Inglewood, California. The Bank is subject to significant competition from other financial institutions, and is also subject to regulation by certain federal agencies and undergoes periodic examinations by those regulatory authorities. The consolidated financial statements include the accounts of the Company and its wholly owned subsidiary, Broadway Federal Bank, f.s.b.. All significant inter-company transactions and balances have been eliminated in consolidation.
Use of Estimates	Use of Estimates To prepare consolidated 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 consolidated financial statements and the disclosures provided, and actual results could differ from these estimates. The allowance and provision for loan losses, specific reserves for impaired loans, fair value of real estate owned, deferred tax asset valuation allowance, and fair values of investment securities and other financial instruments are particularly subject to change.
Cash Flows	Cash Flows Cash and cash equivalents include cash on hand, cash items in the process of collection, and amounts due from correspondent banks, the Federal Reserve Bank and interest-bearing deposits in other banks with initial terms of ninety days or less. The Company may be required to maintain reserve and clearing balances with the Federal Reserve Bank under the Federal Reserve Act. The reserve and clearing requirement balance was $0 at December 31, 2016. Net cash flows are reported for customer loan and deposit transactions, deferred income taxes and other assets and liabilities.
Securities	Securities Debt securities are classified as held-to-maturity and carried at amortized cost when management has the positive intent and ability to hold them to maturity. Debt securities are classified as available-for-sale when they might be sold before maturity. Securities available-for-sale are carried at fair value, with unrealized holding gains and losses reported in other comprehensive income (loss), net of tax. Interest income includes amortization of purchase premium or discount. Premiums and discounts on securities are amortized on the level-yield method without anticipating prepayments, except for mortgage backed securities where prepayments are anticipated. 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") on at least a quarterly basis, and more frequently when economic or market conditions warrant such an evaluation. Consideration is given to the financial condition and near-term prospects of the issuer, the length of time and the extent to which the fair value has been less than the cost, and the intent and ability of management to retain its investment in the issuer for a period of time sufficient to allow for any anticipated recovery in fair value. In analyzing an issuer's financial condition, management considers whether the securities are issued by the federal government or its agencies, whether downgrades by bond rating agencies have occurred, and the results of reviews of the issuer's financial condition.
Loans Receivable Held for Sale	Loans Receivable Held for Sale The Bank originates loans for investment but may, from time-to-time, decide to sell certain loans in order to manage loan concentrations. When a decision is made to sell a loan(s), such loan(s) is transferred from held-for-investment portfolio to held-for-sale portfolio at the lower of cost or fair value, as determined by outstanding commitments from investors. If a reduction in value is required at time of the transfer, a charge-off is recorded against the allowance for loan losses ("ALLL"). Any subsequent decline in value of the loan(s) is recorded as a valuation allowance with a corresponding charge to non-interest expense. Loans receivable held for sale are generally sold with servicing rights released. Gains and losses on sales of loans are based on the difference between the selling price and the carrying value of the related loan sold. When loans receivable held for sale are sold, existing deferred loan fees or costs are an adjustment of the gain or loss on sale.
Loans Receivable Held for Investment	Loans Receivable Held for Investment Loans 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, net of allowance for loan losses, deferred loan fees and costs and unamortized premiums and discounts. Interest income is accrued on the unpaid principal balance. Loan origination fees, net of certain direct loan origination costs, premiums and discounts are deferred, and recognized in income using the level-yield method without anticipating prepayments. Interest income on all loans is discontinued at the time the loan is 90 days delinquent unless the loan is well-secured and in process of collection. Past due status is based on the contractual terms of the loan. In all cases, loans are placed on non-accrual or charged-off at an earlier date if collection of principal or interest is considered doubtful. All interest accrued but not received for loans placed on non-accrual is reversed against interest income. Interest received on such loans is accounted for on the cash-basis or cost recovery method, until qualifying for return to accrual. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured.
Concentration of Credit Risk	Concentration of Credit Risk Concentrations of credit risk arise when a number of customers are engaged in similar business activities, or activities in the same geographic region, or have similar economic features that would cause their ability to meet contractual obligations to be similarly affected by changes in economic conditions. The Company's lending activities are predominantly in real estate loans that are secured by properties located in Southern California and many of the borrowers reside in Southern California. Therefore, the Company's exposure to credit risk is significantly affected by changes in the economy and real estate market in the Southern California area. The Company has a significant concentration of deposits with a long-time customer that accounted for approximately 11% of its deposits as of December 31, 2016. The Company expects to maintain this relationship with the customer for the near term.
Loans Purchased	Loans Purchased The Bank purchases or participates in loans originated by other institutions from time to time. Subject to regulatory restrictions applicable to savings institutions, the Bank's current loan policies allow all loan types to be purchased. The determination to purchase specific loans or pools of loans is based upon the Bank's investment needs and market opportunities and is subject to the Bank's underwriting policies, which require consideration of the financial condition of the borrower and the appraised value of the property, among other factors. Purchased loans are initially recorded at fair value with no allowance for loan losses, as an element of credit loss is inherent in the fair value. Premiums or discounts incurred upon the purchase of loans are recognized in income using the interest method over the estimated life of the loans, adjusted for prepayments. No loans were purchased during 2016. In December 2015, the Company purchased $99.7 million of single family loans at a premium. For these purchased loans, the Company did not incur any provisions for loan losses during the years ended December 31, 2016, and 2015. The Company determined that it was probable at acquisition that all contractually required payments would be collected. The Company may recognize provisions for loan losses in the future should there be deterioration in these loans.
Allowance for Loan Losses	Allowance for Loan Losses The allowance for loan losses is a valuation allowance for probable incurred credit losses. Loan losses are charged against the allowance when management believes the uncollectability of a loan balance is confirmed. Subsequent cash 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, could be charged off. In addition, the OCC and FDIC periodically review the allowance for loan losses as an integral part of their examination process. These agencies may require an increase in the allowance for loan losses based on their judgments of the information available to them at the time of their examinations. 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 the Company will be unable to collect all amounts due according to the contractual terms of the loan agreement. Loans 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 ("TDR") and classified as impaired. Factors considered by management in determining impairment 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 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. If a loan is impaired, either 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 alternatively a charge-off is taken to record the loan at the fair value of the collateral, less estimated selling costs, if repayment is expected solely from the collateral. Troubled debt restructurings are separately identified for impairment disclosures and are measured at the present value of estimated future cash flows using the loan's effective rate at inception. If a troubled debt restructuring is considered to be a collateral dependent loan, the loan is reported, net, at the fair value of the collateral. For troubled debt restructurings that subsequently default, the Company determines the amount of any necessary additional charge-off based on internal analyses and appraisals of the underlying collateral securing these loans. The general component covers non-impaired loans and is based on historical loss experience adjusted for current factors. The historical loss experience is determined by portfolio segment with the use of a loss migration analysis and is based on the actual loss history experienced by the Company over the most recent three years. This actual loss experience is supplemented with information about other current economic factors based on the risks present for each portfolio segment. These current economic 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: one-to-four units ("single family"), five or more units ("multi-family"), commercial real estate, church, construction, commercial loans, and consumer loans. The risks in our various portfolio segments are as follows: Single Family – Subject to adverse employment conditions in the local economy leading to increased default rate; decreased market values from oversupply in a geographic area; impact on borrowers' ability to maintain payments in the event of incremental rate increases on adjustable rate mortgages. Multi-Family – Subject to adverse various market conditions that cause a decrease in market value or lease rates; change in personal funding sources for tenants; oversupply of units in a specific region; a shift in population; reputational risks. Commercial Real Estate – Subject to adverse conditions in the local economy which may lead to reduced cash flows due to vacancies and reduced rental rates; decreases in the value of underlying collateral. Church – Subject to adverse economic and employment conditions leading to reduced cash flows from members' donations and offerings; the stability, quality and popularity of church leadership. Construction – Subject to adverse conditions in the local economy which may lead to reduced demand for new commercial, multi-family or single family buildings or reduced lease or sale opportunities once the building is complete. Commercial – Subject to industry and economic conditions including decreases in product demand. Consumer – Subject to adverse employment conditions in the local economy, which may lead to higher default rates.
Real Estate Owned	Real Estate Owned Assets acquired through, or instead of, loan foreclosure are initially recorded at fair value less estimated 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, a valuation allowance is recorded through a provision that is charged to non-interest expense. Operating costs after acquisition are expensed as incurred.
Office Properties and Equipment	Office Properties 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 10 to 40 years. Furniture, fixtures and equipment are depreciated using the straight-line method with useful lives ranging from 3 to 10 years. Leasehold improvements are amortized over the lease term or the estimated useful life of the asset, whichever is shorter.
Federal Home Loan Bank (FHLB) stock	Federal Home Loan Bank (FHLB) stock The Bank 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 when declared.
Bank-Owned Life Insurance	Bank-Owned Life Insurance The Bank has purchased life insurance policies on a former key executive. 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.
Investment in Affordable Housing Limited Partnership	Investment in Affordable Housing Limited Partnership The Bank owns a less than 5% interest in an affordable housing limited partnership. The investment is recorded using the cost method and is being amortized over the life of the related tax credits. The tax credits are being recognized in income tax expense in the consolidated financial statements to the extent they are utilized on the Company's income tax returns. The investment is reviewed for impairment on an annual basis or on an interim basis if an event occurs that would trigger potential impairment.
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.
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 bases of assets and liabilities, computed using enacted tax rates. A valuation allowance, if needed, reduces deferred tax assets to the amount expected to be realized. 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 in interest expense and penalties related to tax matters in income tax expense.
Retirement Plans	Retirement Plans Employee 401(k) expense is the amount of matching contributions made by the Company. Deferred compensation plan expense allocates the benefits over years of service. The Bank makes discretionary cash contributions to participant ESOP accounts up to 25% of eligible compensation.
Earnings Per Common Share	Earnings Per Common Share Basic earnings per common share is computed pursuant to the two-class method by dividing net income available to common stockholders less dividends paid on participating securities (unvested shares of restricted common stock) and any undistributed earnings attributable to participating securities by the weighted average common shares outstanding during the period. The weighted average common shares outstanding includes the weighted average number of shares of common stock outstanding less the weighted average number of unvested shares of restricted common stock. ESOP shares are considered outstanding for this calculation unless unearned. 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 or loss. Other comprehensive income or loss includes unrealized gains and losses on securities available-for-sale, net of tax, which are also recognized as separate components 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 that any such matters existed as of the balance sheet date that will have a material effect on the consolidated financial statements.
Fair Value Measurements	Fair Value Measurements Fair value is the exchange price that would be received for an asset or paid to transfer a liability (exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. There are three levels of inputs that may be used to measure fair values: Level 1: Quoted prices (unadjusted) for identical assets or liabilities in active markets that the entity has the ability to access as of the measurement date. Level 2: Significant 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. Fair values are estimated using relevant market information and other assumptions, as more fully disclosed in Note 4. 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 the estimates.
Operating Segments	Operating Segments The Company operates as a single segment. The operating information used by management to assess performance and make operating decisions about the Company is the consolidated financial data presented in these financial statements. For the years ended 2016 and 2015, the Company had one active operating subsidiary, Broadway Federal Bank, f.s.b. The Company has determined that banking is its one reportable business segment.
Reclassifications	Reclassifications Some items in the prior year consolidated financial statements were reclassified to conform to the current presentation. Reclassifications had no effect on prior year consolidated net income or stockholders' equity.
Adoption of New Accounting Standards	Adoption of New Accounting Standards In May 2014, the FASB issued ASU 2014-09, "Revenue from Contracts with Customers (Topic 606)". ASU 2014-09 replaced existing revenue recognition guidance for contracts to provide goods or services to customers. The new guidance clarifies the principles for recognizing revenue and replaces nearly all existing revenue recognition guidance in U.S. GAAP. Quantitative and qualitative disclosures regarding the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers are also required. ASU 2014-09 as amended by ASU 2015-14, ASU 2016-08, ASU 2016-10, ASU 2016-12 and ASU 2016-20, is effective for interim and annual periods beginning after December 15, 2017 and is applied on either a modified retrospective or full retrospective basis. Early adoption is permitted for interim and annual periods beginning after December 15, 2016. The Company's revenue is mainly comprised of net interest income from financial assets and liabilities, which is explicitly excluded from the scope of the new guidance, and noninterest income. The Company continues to evaluate the impact of ASU 2014-09 on our noninterest income and on our presentation and disclosures. The Company's implementation efforts include the identification of revenue within the scope of ASU 2014-09 and the review is on-going. In January 2016, the FASB issued ASU 2016-1, "Financial Instruments – Overall (Subtopic 825-10) – Recognition and Measurement of Financial Assets and Financial Liabilities". ASU 2016-1 (i) requires equity investments, with certain exceptions, to be measured at fair value with changes in fair value recognized in net income; (ii) simplifies the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment; (iii) eliminates the requirement for public business entities to disclose the methods and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet; (iv) requires public business entities to use the exit price notion when measuring the fair value of financial instruments for disclosure purposes; (v) requires an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments; (vi) requires separate presentation of financial assets and financial liabilities by measurement category and form of financial asset on the balance sheet or the accompanying notes to the financial statements; and (vii) clarifies that an entity should evaluate the need for a valuation allowance on a deferred tax asset related to available-for-sale. For public business entities, the amendments in ASU 2016-01 are effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early application by public business entities to financial statements of fiscal years or interim periods that have not yet been issued are permitted as of the beginning of the fiscal year of adoption. Adoption of this standard is not expected to have a material impact on the Company's consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, "Leases (Topic 842)". Under ASU 2016-02, lessees will be required to recognize the following for all leases (with the exception of short-term leases, as defined) at the commencement date: (i) a lease liability, which is a lessee's obligation to make lease payments arising from a lease, measured on a discounted basis; and (ii) a right-of-use asset, which is an asset that represents the lessee's right to use, or control the use of, a specified asset for the lease term. Under the new guidance, lessor accounting is largely unchanged. Public business entities should apply the amendments in ASU 2016-02 for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. Lessees (for capital and operating leases) and lessors (for sales-type, direct financing, and operating leases) must apply a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. The Company is currently evaluating the impact of the pending adoption of the new standard on its consolidated financial statements. The Company expects a gross-up of its Consolidated Statements of Condition as a result of recognizing lease liabilities and right of use assets. The Company does not expect a material impact to its recognition of operating lease expense on its Consolidated Statements of Income and Comprehensive Income. In March 2016, the FASB issued ASU 2016-09, "Compensation – Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting". ASU 2016-09 includes provisions intended to simplify various aspects related to how share-based payments are accounted for and presented in the financial statements. The areas for simplification include income tax consequences, forfeitures, classification of awards as either equity or liabilities and classification on the statement of cash flows. ASU 2016-09 is effective for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years. Early adoption is permitted. Adoption of this standard is not expected to have a material impact on the Company's consolidated financial statements. In June 2016, the FASB issued ASU 2016-13, "Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments". ASU 2016-13 requires an organization to measure all expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. Financial institutions and other organizations will now use forward-looking information to better inform their credit loss estimates. Many of the loss estimation techniques applied today will still be permitted, although the inputs to those techniques will change to reflect the full amount of expected credit losses over the life of the related financial assets. Organizations will continue to use judgment to determine which loss estimation method is appropriate for their circumstances. Additionally, the ASU amends the accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration. For public business entities, ASU 2016-13 is effective for fiscal years beginning after December 15, 2019, and interim periods within those fiscal years. Early adoption is permitted. While the Company is still evaluating the impact on its consolidated financial statements, the Company expects that ASU 2016-13 may result in an increase in the allowance for credit losses due to the following factors: 1) the allowance for credit losses will increase to provide for expected credit losses over the remaining expected life of the loan portfolio, and will consider expected future changes in macroeconomic conditions; and 2) an allowance may be established for estimated credit losses on available-for-sale debt securities. The amount of increase will be impacted by the portfolio composition and quality, as well as the economic conditions and forecasts as of the adoption date. The Company has began its implementation efforts by identifying key interpretive issues, and assessing its processes and identifying the system requirements against the new guidance to determine what modifications may be required. In August 2016, the FASB issued ASU 2016-15, "Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments". ASU 2016-15 provides guidance on the classification of certain cash receipts and payments on the consolidated statement of cash flows in order to reduce diversity in practice. ASU 2016-15 is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted. Adoption of this standard is not expected to have a material impact on the Company's consolidated financial statements. In November 2016, the FASB issued ASU 2016-18, "Statement of Cash Flows (Topic 230): Restricted Cash". ASU 2016-18 requires entities to show the changes in the total of cash, cash equivalents, restricted cash and restricted cash equivalents in the statement of cash flows. As a result, entities will no longer present transfers between cash and cash equivalents and restricted cash and restricted cash equivalents in the statement of cash flows. ASU 2016-18 is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years, where the guidance should be applied using a retrospective transition method to each period presented. Early adoption is permitted. Adoption of this standard is not expected to have a material impact on the Company's consolidated financial statements.
