Note 1 - Summary of Significant Accounting Policies

3 Months Ended

Mar. 31, 2021

Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block]

NOTE 1 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation: BankFinancial Corporation, a Maryland corporation headquartered in Burr Ridge, Illinois, is the owner of all of the issued and outstanding capital stock of BankFinancial, NA (the “Bank”). The interim unaudited consolidated financial statements include the accounts and transactions of BankFinancial Corporation, the Bank, and the Bank’s wholly-owned subsidiaries, Financial Assurance Services, Inc. and BFIN Asset Recovery Company, LLC (collectively, “the Company”), and reflect all normal and recurring adjustments that are, in the opinion of management, considered necessary for a fair presentation of the financial condition and results of operations for the periods presented. Such adjustments are the only adjustments reflected in the accompanying financial statements. All significant intercompany accounts and transactions have been eliminated. The results of operations for the three month period ended March 31, 2021 are not necessarily indicative of the results of operations that may be expected for the year ending December 31, 2021 or for any other period.

Certain information and note disclosures normally included in financial statements prepared in conformity with accounting principles generally accepted in the United States of America (“US GAAP”) have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”).

Use of Estimates: The preparation of the consolidated financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Although these estimates and assumptions are based on the best available information, actual information, actual results could differ from those estimates.

COVID-19: On March 11, 2020, the World Health Organization declared the outbreak of a novel coronavirus (“COVID-19”) as a global pandemic. The declaration of a global pandemic indicates that almost all public commerce and related business activities must be, to varying degrees, curtailed with the goal of decreasing the rate of new infections. The outbreak of COVID-19 has adversely impacted, and could further adversely impact, a broad range of industries in which the Company’s customers operate and impair their ability to fulfill their financial obligations to the Company. On March 3, 2020, the Federal Open Market Committee reduced the target federal funds rate range by 50 basis points to 1.00% to 1.25%. This rate was further reduced to a target range of 0% to 0.25% on March 16, 2020. These reductions in interest rates and other effects of the COVID-19 outbreak may adversely affect the Company’s financial condition and results of operations. As a result of the spread of the COVID-19 coronavirus, economic uncertainties have arisen which are likely to negatively impact net interest income and noninterest income. Other financial impacts could occur though such potential impact is unknown at this time.

Reclassifications: Certain reclassifications have been made in the prior period’s financial statements to conform them to the current period’s presentation.

These unaudited consolidated financial statements should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2020, as filed with the Securities and Exchange Commission.

Newly Issued Not Yet Effective Accounting Standards

In June 2016, the FASB issued ASU No. 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments” (“ASU 2016-13”). These amendments require the measurement of 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. In addition, the ASU amends the accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration. For SEC filers who are smaller reporting companies, such as the Company, ASU 2016-13 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2022.

The Company evaluates marketable investment securities with significant declines in fair value on a quarterly basis to determine whether they should be considered other-than-temporarily impaired under current accounting guidance, which generally provides that if a marketable security is in an unrealized loss position, whether due to general market conditions or industry or issuer-specific factors, the holder of the securities must assess whether the impairment is other-than-temporary.

There were no unrealized loss positions at March 31, 2021. Certain collateralized mortgage obligations that the Company holds in its investment portfolio were in an unrealized loss position at December 31, 2020, but the unrealized loss was not considered significant under the Company’s impairment testing methodology. In addition, the Company does not intend to sell these securities, and it is likely that the Company will not be required to sell these securities before their anticipated recovery occurs.

Nonaccrual loans and impaired loans are defined differently. Some loans may be included in both categories, and some loans may only be included in one category. Nonaccrual loans include both smaller balance homogeneous loans that are collectively evaluated for impairment and individually classified impaired loans.

The Company’s reserve for uncollected loan interest was $113,000 and $133,000 at March 31, 2021 and December 31, 2020, respectively. When a loan is on nonaccrual status and the ultimate collectability of the total principal of an impaired loan is in doubt, all payments are applied to principal under the cost recovery method. Alternatively, when a loan is on nonaccrual status but there is doubt concerning only the ultimate collectability of interest, contractual interest is credited to interest income only when received, under the cash basis method pursuant to the provisions of FASB ASC 310–10, as applicable. In all cases, the average balances are calculated based on the month–end balances of the financing receivables within the period reported pursuant to the provisions of FASB ASC 310–10, as applicable.

U.S. Small Business Administration Paycheck Protection Program ("PPP")

In response to the COVID-19 pandemic, the Coronavirus Aid, Relief and Economic Security Act ("CARES Act") was passed by Congress and signed into law on March 27, 2020. The CARES Act established the Paycheck Protection Program loan, designed to provide a direct incentive for small businesses to keep their workers on the payroll. Under the most recently published guidance, the U.S. Small Business Administration ("SBA") will forgive PPP loans if all employee retention criteria are met, and the funds are used for eligible expenses.

The following table presents the PPP activity:

COVID-19 Loan Forbearance Programs

Section 4013 of the CARES Act provides that a qualified loan modification is exempt by law from classification as a Troubled Debt Restructuring ("TDR") pursuant to US GAAP. In addition, the Revised Interagency Statement on Loan Modifications and Reporting for Financial Institutions Working With Customers Affected by the Coronavirus (“OCC Bulletin 2020-50”) provides more limited circumstances in which a loan modification is not subject to classification as a TDR and also defined the circumstances where the borrower’s loan is reported as current on loan payments. Pursuant to these new capabilities, we developed several loan forbearance programs to assist borrowers with managing cash flows disrupted due to COVID-19.

Our Apartment and Commercial Real Estate COVID-19 Qualified Limited Forbearance Agreement permitted borrowers who qualified under Section 4013 of the CARES Act to make an election to pay only scheduled interest and escrow payments (if applicable) for a four-month period beginning in April 2020, and pay all deferred principal payments by December 2020.

Our Small Investment Property COVID-19 Qualified Limited Forbearance Agreement permitted borrowers with loan balances under $750,000 who qualified under Section 4013 of the CARES Act to make an election to pay only scheduled interest and escrow payments (if applicable) for a four-month period beginning in April 2020, and pay all deferred principal payments by December 2020. In addition, the borrower could elect to defer the May 2020 loan payment entirely, with all deferred interest amounts due by December 2020 and all deferred principal amounts due by June 30, 2021.

CARES Act Section 4013 and OCC Bulletin 2020-35 forbearance agreements are available to qualified commercial loan and commercial finance borrowers, and to commercial equipment lessees.

For residential mortgage and consumer loans, relief under CARES Act Section 4013 or OCC Bulletin 2020-35 forbearance agreements are available to qualified borrowers with terms consistent with secondary residential mortgage market standards established by Fannie Mae.

The following table summarizes the remaining loan forbearance modifications:

Troubled Debt Restructurings

The Company evaluates loan extensions or modifications not qualified under Section 4013 of the CARES Act or under OCC Bulletin 2020-35 in accordance with FASB ASC 340-10 with respect to the classification of the loan as a TDR.

Under ASC 340-10, if the Company grants a loan extension or modification to a borrower experiencing financial difficulties for other than an insignificant period of time that includes a below–market interest rate, principal forgiveness, payment forbearance or other concession intended to minimize the economic loss to the Company, the loan extension or loan modification is classified as a TDR. In cases where borrowers are granted new terms that provide for a reduction of either interest or principal then due and payable, management measures any impairment on the restructured loan in the same manner as for impaired loans as noted above.

The Company had no TDRs at March 31, 2021 and December 31, 2020. During the three months ended March 31, 2021 and 2020, there were no loans modified and classified as TDRs. During the three months ended March 31, 2021 and 2020, there were no TDR loans that subsequently defaulted within twelve months of their modification.

A loan is considered to be in payment default once it is 90 days contractually past due under the modified terms.

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.

Credit Quality Indicators

The Company categorizes loans into risk categories based on relevant information about the ability of borrowers to service their debt, including current financial information, historical payment experience, credit documentation, public information, and current economic trends, among other factors. The Company analyzes loans individually by classifying the loans based on credit risk. This analysis includes non-homogeneous loans, such as commercial and commercial real estate loans. This analysis is performed on a monthly basis. The Company uses the following definitions for risk ratings:

Special Mention. A Special Mention asset has potential weaknesses that deserve management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the asset or in the institution’s credit position at some future date. Special Mention assets are not adversely classified and do not expose an institution to sufficient risk to warrant adverse classification.

Substandard. Loans categorized as Substandard continue to accrue interest, but exhibit a well-defined weakness or weaknesses that may jeopardize the liquidation of the debt. The loans continue to accrue interest because they are well secured and collection of principal and interest is expected within a reasonable time. The risk rating guidance published by the Office of the Comptroller of the Currency clarifies that a loan with a well-defined weakness does not have to present a probability of default for the loan to be rated Substandard, and that an individual loan’s loss potential does not have to be distinct for the loan to be rated Substandard.

Nonaccrual. An asset classified Nonaccrual has all the weaknesses inherent in one classified Substandard with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable.

Loans not meeting the criteria above that are analyzed individually as part of the above described process are considered “Pass” rated loans.

Based on the most recent analysis performed, the risk categories of loans by class of loans are as follows:

	*Pass*		*Special Mention*		*Substandard*		*Nonaccrual*		*Total*

Foreclosed Assets [Text Block]

NOTE 5 - FORECLOSED ASSETS

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

Assets are classified as foreclosed when physical possession of the collateral is taken regardless of whether foreclosure proceedings have taken place. Other foreclosed assets received in satisfaction of borrowers debt are initially recorded at fair value of the asset less estimated costs to sell.

At March 31, 2021 and December 31, 2020, the balance of OREO includes no foreclosed residential real estate properties recorded as a result of obtaining physical possession of the property without title. At March 31, 2021 and December 31, 2020, the recorded investment of consumer mortgage loans secured by residential real estate properties for which formal foreclosure proceedings were in process was $158,000 and $187,000, respectively. The other foreclosed assets consist of non real estate collateral repossessed related to a previously classified Chicago area commercial loan.

Fair Value Disclosures [Text Block]

NOTE 8 – FAIR VALUE

Fair value is the exchange price that would be received for an asset or paid to transfer a liability (exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. There are three levels of inputs that may be used to measure fair values:

•

Level 1 – Quoted prices (unadjusted) for identical assets or liabilities in active markets that the entity has the ability to access as of the measurement date.


	•	Level 2 – Significant other observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data.


	•	Level 3 – Significant unobservable inputs that reflect a company’s own assumptions about the assumptions that market participants would use in pricing an asset or liability.

The Company used the following methods and significant assumptions to estimate the fair value of each type of financial instrument:

Securities: The fair values of debt securities are generally determined by matrix pricing, which is a mathematical technique widely used in the industry to value debt securities without relying exclusively on quoted prices for the specific securities, but rather by relying on the securities’ relationship to other benchmark quoted securities (Level 2).

Impaired loans: The fair value of impaired loans with specific allocations of the allowance for loan losses is generally based on recent real estate appraisals. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach. Adjustments are routinely made in the appraisal process by the independent appraisers to adjust for differences between the comparable sales and income data available for similar loans and collateral underlying such loans. Non-real estate collateral may be valued using an appraisal, net book value per the borrower’s financial statements, or aging reports, adjusted or discounted based on management’s historical knowledge, changes in market conditions from the time of the valuation, and management’s expertise and knowledge of the client and client’s business, resulting in a Level 3 fair value classification. Impaired loans are evaluated on a quarterly basis for additional impairment and adjusted in accordance with the allowance policy.

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. Fair value is commonly based on recent real estate appraisals which are updated no less frequently than annually. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach with data from comparable properties. Adjustments are routinely made in the appraisal process by the independent appraisers to adjust for differences between the comparable sales and income data available. Foreclosed assets are evaluated on a quarterly basis for additional impairment and adjusted accordingly.

The following table sets forth the Company’s financial assets that were accounted for at fair value and are classified in their entirety based on the lowest level of input that is significant to the fair value measurement.

Impaired loans, which are measured for impairment using the fair value of the collateral for collateral–dependent loans, had a carrying amount of $296,000, with a valuation allowance of $28,000 at March 31, 2021 and December 31, 2020. There was no change in the provision for loan losses of $28,000 for the three months ended March 31, 2021, compared to no specific provision for loan losses for the three months ended March 31, 2020.

At March 31, 2021 and December 31, 2020, there were no foreclosed assets with valuation allowances.

The following table presents quantitative information, based on certain empirical data with respect to Level 3 fair value measurements for financial instruments measured at fair value on a non-recurring basis:

Loans: The exit price observations are obtained from an independent third-party using its proprietary valuation model and methodology and may not reflect actual or prospective market valuations. The valuation is based on the probability of default, loss given default, recovery delay, prepayment, and discount rate assumptions.

While the above estimates are based on management’s judgment of the most appropriate factors, as of the balance sheet date, there is no assurance that the estimated fair values would have been realized if the assets were disposed of or the liabilities settled at that date, since market values may differ depending on the various circumstances. The estimated fair values would also not apply to subsequent dates.

In addition, other assets and liabilities that are not financial instruments, such as premises and equipment, are not included in the above disclosures.

The entire disclosure for the fair value of financial instruments (as defined), including financial assets and financial liabilities (collectively, as defined), and the measurements of those instruments as well as disclosures related to the fair value of non-financial assets and liabilities. Such disclosures about the financial instruments, assets, and liabilities would include: (1) the fair value of the required items together with their carrying amounts (as appropriate); (2) for items for which it is not practicable to estimate fair value, disclosure would include: (a) information pertinent to estimating fair value (including, carrying amount, effective interest rate, and maturity, and (b) the reasons why it is not practicable to estimate fair value; (3) significant concentrations of credit risk including: (a) information about the activity, region, or economic characteristics identifying a concentration, (b) the maximum amount of loss the entity is exposed to based on the gross fair value of the related item, (c) policy for requiring collateral or other security and information as to accessing such collateral or security, and (d) the nature and brief description of such collateral or security; (4) quantitative information about market risks and how such risks are managed; (5) for items measured on both a recurring and nonrecurring basis information regarding the inputs used to develop the fair value measurement; and (6) for items presented in the financial statement for which fair value measurement is elected: (a) information necessary to understand the reasons for the election, (b) discussion of the effect of fair value changes on earnings, (c) a description of [similar groups] items for which the election is made and the relation thereof to the balance sheet, the aggregate carrying value of items included in the balance sheet that are not eligible for the election; (7) all other required (as defined) and desired information.

NOTE 9 – REVENUE FROM CONTRACTS WITH CUSTOMERS

All of the Company's revenue from contracts with customers within the scope of ASC 606 is recognized within noninterest income. The following table presents the Company's sources of noninterest income. Items outside of the scope of the ASC 606 are noted as such.

⁽¹⁾ Not within the scope of ASC 606

A description of the Company's revenue streams accounted for under ASC 606 follows:

Deposit service charges and fees: The Company earns fees from its deposit customers based on specific types of transactions, account maintenance and overdraft services. Transaction-based fees, which include services such as ATM use fees, stop payment charges, statement rendering, and ACH fees, are recognized at the time the transaction is executed as that is the point in time the Company fulfills the customer's request. Account maintenance fees, which relate primarily to monthly maintenance, are earned over the course of a month, representing the period over which the Company satisfies the performance obligation. Overdraft fees are recognized at the point in time that the overdraft occurs. Service charges on deposits are withdrawn from the customer's account balance.

Interchange income: The Company earns interchange fees from debit cardholder transactions conducted through the Visa payment network. Interchange fees from cardholder transactions represent a percentage of the underlying transaction value and are recognized daily, concurrently with the transaction processing services provided to the cardholder. Interchange income is included in deposit service charges and fees. Interchange income was $381,000 and $351,000 for the three months ended March 31, 2021 and 2020, respectively.

Trust and insurance commissions and annuities income: The Company earns trust, insurance commissions and annuities income from its contracts with trust customers to manage assets for investment, and/or to transact on their accounts. These fees are primarily earned over time as the Company provides the contracted monthly or quarterly services and are generally assessed based on a tiered scale of the market value of assets under management (AUM) at month-end. Fees that are transaction based, including trade execution services, are recognized at the point in time that the transaction is executed, i.e., the trade date. Other related services provided include fees the Company earns, which are based on a fixed fee schedule, are recognized when the services are rendered.

Gains/losses on sales of OREO and other assets: The Company records a gain or loss from the sale of OREO and other assets when control of the property transfers to the buyer, which generally occurs at the time of an executed deed. When the Company finances the sale of OREO to the buyer, the Company assesses whether the buyer is committed to perform their obligations under the contract and whether collectability of the transaction price is probable. Once these criteria are met, the OREO asset is derecognized and the gain or loss on sale is recorded upon the transfer of control of the property to the buyer. In determining the gain or loss on the sale, the Company adjusts the transaction price and related gain (loss) on sale if a significant financing component is present. OREO sales for the three months ended March 31, 2020 were not financed by the Company. There were no sales of OREO for the three months ended March 31, 2021.

The entire disclosure of revenue from contract with customer to transfer good or service and to transfer nonfinancial asset. Includes, but is not limited to, disaggregation of revenue, credit loss recognized from contract with customer, judgment and change in judgment related to contract with customer, and asset recognized from cost incurred to obtain or fulfill contract with customer. Excludes insurance and lease contracts.

Subsequent Events [Text Block]

NOTE 10 – SUBSEQUENT EVENT

On April 14, 2021, the Company entered into Subordinated Note Purchase Agreements (collectively, the “Purchase Agreement”) with certain qualified institutional buyers and accredited investors (the “Purchasers”) pursuant to which the Company sold and issued $20.0 million in aggregate principal amount of its 3.75% Fixed-to-Floating Rate Subordinated Notes due May 15, 2031 (the “Notes”). The Notes were offered and sold by the Company to eligible purchasers in a private offering in reliance on the exemption from the registration requirements of Section 4(a)(2) of the Securities Act of 1933, as amended and the provisions of Regulation D promulgated thereunder.

The Notes will bear interest at a fixed annual rate of 3.75%, from and including the date of issuance to but excluding May 15, 2026, payable semi-annually in arrears. From and including May 15, 2026 to, but excluding the maturity date or early redemption date, the interest rate will reset quarterly to an interest rate per annum equal to Three-Month Term SOFR (as defined in the Note) plus 299 basis points, payable quarterly in arrears. As provided in the Notes, under specified conditions the interest rate on the Notes during the applicable floating rate period may be determined based on a rate other than Three-Month Term SOFR.

The Notes have a stated maturity date of May 15, 2031 and are redeemable, in whole or in part, on May 15, 2026, on any interest payment date thereafter, and at any time upon the occurrence of certain events. The Purchase Agreement contains certain customary representations, warranties and covenants made by the Company, on the one hand, and the Purchasers, severally and not jointly, on the other hand. The Notes are not entitled to the benefit of any sinking fund and are not convertible into or exchangeable for any of the equity securities, other securities or assets of the Company or any of its subsidiaries.

Principal and interest on the Notes are subject to acceleration only in limited circumstances in the case of certain bankruptcy and insolvency-related events with respect to the Company. The Notes are unsecured, subordinated obligations of the Company and generally rank junior in right of payment to the Company’s current and future senior indebtedness. The Notes are intended to qualify as Tier 2 capital of the Company for regulatory capital purposes.

Significant Accounting Policies (Policies)	3 Months Ended
Significant Accounting Policies (Policies)	Mar. 31, 2021
Accounting Policies [Abstract]
Basis of Accounting, Policy [Policy Text Block]	Basis of Presentation: BankFinancial Corporation, a Maryland corporation headquartered in Burr Ridge, Illinois, is the owner of all of the issued and outstanding capital stock of BankFinancial, NA (the “Bank”). The interim unaudited consolidated financial statements include the accounts and transactions of BankFinancial Corporation, the Bank, and the Bank’s wholly-owned subsidiaries, Financial Assurance Services, Inc. and BFIN Asset Recovery Company, LLC (collectively, “the Company”), and reflect all normal and recurring adjustments that are, in the opinion of management, considered necessary for a fair presentation of the financial condition and results of operations for the periods presented. Such adjustments are the only adjustments reflected in the accompanying financial statements. All significant intercompany accounts and transactions have been eliminated. The results of operations for the three month period ended March 31, 2021 are not necessarily indicative of the results of operations that may be expected for the year ending December 31, 2021 or for any other period. Certain information and note disclosures normally included in financial statements prepared in conformity with accounting principles generally accepted in the United States of America (“US GAAP”) have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”).
Use of Estimates, Policy [Policy Text Block]	Use of Estimates: The preparation of the consolidated financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Although these estimates and assumptions are based on the best available information, actual information, actual results could differ from those estimates.
Covid-19 [Policy Text Block]	COVID-19: On March 11, 2020, the World Health Organization declared the outbreak of a novel coronavirus (“COVID-19”) as a global pandemic. The declaration of a global pandemic indicates that almost all public commerce and related business activities must be, to varying degrees, curtailed with the goal of decreasing the rate of new infections. The outbreak of COVID-19 has adversely impacted, and could further adversely impact, a broad range of industries in which the Company’s customers operate and impair their ability to fulfill their financial obligations to the Company. On March 3, 2020, the Federal Open Market Committee reduced the target federal funds rate range by 50 basis points to 1.00% to 1.25%. This rate was further reduced to a target range of 0% to 0.25% on March 16, 2020. These reductions in interest rates and other effects of the COVID-19 outbreak may adversely affect the Company’s financial condition and results of operations. As a result of the spread of the COVID-19 coronavirus, economic uncertainties have arisen which are likely to negatively impact net interest income and noninterest income. Other financial impacts could occur though such potential impact is unknown at this time.
Reclassification, Comparability Adjustment [Policy Text Block]	Reclassifications: Certain reclassifications have been made in the prior period’s financial statements to conform them to the current period’s presentation. These unaudited consolidated financial statements should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2020, as filed with the Securities and Exchange Commission.
New Accounting Pronouncements, Policy [Policy Text Block]	*Newly Issued Not* Yet Effective Accounting Standards** In June 2016, the FASB issued ASU No. 2016-13, “Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments” (“ASU 2016-13”). These amendments require the measurement of 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. In addition, the ASU amends the accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration. For SEC filers who are smaller reporting companies, such as the Company, ASU 2016-13 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2022.
