|Nature of Operations [Policy Text Block]
Nature of Operations
ServisFirst Bancshares, Inc. (the “Company”) was formed on August 16, 2007 and is a bank holding company whose business is conducted by its wholly owned subsidiary ServisFirst Bank (the “Bank”). The Bank is headquartered in Birmingham, Alabama, and has provided a full range of banking services to individual and corporate customers throughout the Birmingham market since opening for business in May 2005. The Bank has since expanded into the Huntsville, Montgomery, Dothan and Mobile, Alabama, Pensacola, Sarasota and Tampa Bay, Florida, Atlanta, Georgia, Charleston, South Carolina and Nashville, Tennessee markets. The Bank owns all of the stock of SF Intermediate Holding Company, Inc., which, in turn, owns all of the stock of SF Holding 1, Inc., which, in turn, owns all of the common stock of the Company’s real estate investment trusts, SF Realty 1, Inc., SF FLA Realty, Inc., SF GA Realty, Inc. and SF TN Realty, Inc. More details about SF Intermediate Holding Company, Inc. and its subsidiaries are included in Note 11.
|Reclassification, Policy [Policy Text Block]
Certain amounts reported in prior years have been reclassified to conform to the current year’s presentation. These reclassifications had no effect on the Company’s results of operations, financial position, or net cash flow.
|Basis of Accounting, Policy and Use of Estimates [Policy Text Block]
Basis of Presentation and Accounting Estimates
To prepare consolidated financial statements in conformity with U.S. generally accepted accounting principles, management makes estimates and assumptions based on available information. These estimates and assumptions affect the amounts reported in the financial statements and the disclosures provided, and future results could differ. The allowance for loan losses, valuation of foreclosed real estate, goodwill and other intangible assets and fair values of financial instruments are particularly subject to change. All numbers are in thousands except share and per share data.
|Cash Due From Banks Interest Bearing Balances Due From Financial Institutions [Policy Text Block]
Cash, Due from Banks, Interest-Bearing Balances due from Financial Institutions
Cash and due from banks includes cash on hand, cash items in process of collection, amounts due from banks and interest bearing balances due from financial institutions. For purposes of cash flows, cash and cash equivalents include cash and due from banks and federal funds sold. Generally, federal funds are purchased and sold for one-day periods. Cash flows from loans, mortgage loans held for sale, federal funds sold, and deposits are reported net.
The Bank is required to maintain reserve balances in cash or on deposit with the Federal Reserve Bank based on a percentage of deposits. The total of those reserve balances was approximately $33.9 million at December 31, 2019 and $51.0 million at December 31, 2018.
|Investment, Policy [Policy Text Block]
Securities are classified as available-for-sale when they might be sold before maturity. Unrealized holding gains and losses, net of tax, on securities available for sale are reported as a net amount in a separate component of stockholders’ equity until realized. Gains and losses on the sale of securities available for sale are determined using the specific-identification method. The amortization of premiums and the accretion of discounts are recognized in interest income using methods approximating the interest method over the period to maturity.
Declines in the fair value of available-for-sale securities below their cost that are deemed to be other than temporary are reflected in earnings as realized losses. Securities are classified as held-to-maturity when the Company has the positive intent and ability to hold the securities to maturity. Held-to-maturity securities are reported at amortized cost. In determining the existence of other-than-temporary impairment losses, management considers (1) the length of time and the extent to which the fair value has been less than cost, (2) the financial condition and near-term prospects of the issuer, and (3) the intent and ability of the Company to retain its investment in the issuer for a period of time sufficient to allow for any anticipated recovery in fair value.
|Mortgage Banking Activity [Policy Text Block]
Mortgage Loans Held for Sale
The Company classifies certain residential mortgage loans as held for sale. Typically, mortgage loans held for sale are sold to a third-party investor within a very short time period. The loans are sold without recourse and servicing is not retained. Net fees earned from this banking service are recorded in noninterest income.
In the course of originating mortgage loans and selling those loans in the secondary market, the Company makes various representations and warranties to the purchaser of the mortgage loans. Each loan is underwritten using government agency guidelines. Any exceptions noted during this process are remedied prior to sale. These representations and warranties also apply to underwriting the real estate appraisal opinion of value for the collateral securing these loans. Under the representations and warranties, failure by the Company to comply with the underwriting and/or appraisal standards could result in the Company being required to repurchase the mortgage loan or to reimburse the investor for losses incurred (make whole requests) if such failure cannot be cured by the Company within the specified period following discovery. The Company continues to experience an insignificant level of investor repurchase demands. There were no expenses incurred as part of these buyback obligations for the years ended December 31, 2019 and 2018.
|Policy Loans Receivable, Policy [Policy Text Block]
Loans are reported at unpaid principal balances, less unearned fees and the allowance for loan losses. Interest on all loans is recognized as income based upon the applicable rate applied to the daily outstanding principal balance of the loans. Interest income on nonaccrual loans is recognized on a cash basis or cost recovery basis until the loan is returned to accrual status. A loan may be returned to accrual status if the Company is reasonably assured of repayment of principal and interest and the borrower has demonstrated sustained performance for a period of at least six months. Loan fees, net of direct costs, are reflected as an adjustment to the yield of the related loan over the term of the loan. The Company does not have a concentration of loans to any one industry.
The accrual of interest on loans is discontinued when there is a significant deterioration in the financial condition of the borrower and full repayment of principal and interest is not expected or the principal or interest is more than 90 days past due, unless the loan is both well-collateralized and in the process of collection. Generally, all interest accrued but not collected for loans that are placed on nonaccrual status are reversed against current interest income. Interest collections on nonaccrual loans are generally applied as principal reductions. The Company determines past due or delinquency status of a loan based on contractual payment terms.
A loan is considered impaired when it is probable the Company will be unable to collect all principal and interest payments due according to the contractual terms of the loan agreement. Individually identified impaired loans are measured based on the present value of expected payments using the loan’s original effective rate as the discount rate, the loan’s observable market price, or the fair value of the collateral if the loan is collateral dependent. If the recorded investment in the impaired loan exceeds the measure of fair value, a valuation allowance may be established as part of the allowance for loan losses. Changes to the valuation allowance are recorded as a component of the provision for loan losses.
Impaired loans also include troubled debt restructurings (“TDRs”). In the normal course of business management grants concessions to borrowers, which would not otherwise be considered, where the borrowers are experiencing financial difficulty. The concessions granted most frequently for TDRs involve reductions or delays in required payments of principal and interest for a specified time, the rescheduling of payments in accordance with a bankruptcy plan or the charge-off of a portion of the loan. In some cases, the conditions of the credit also warrant nonaccrual status, even after the restructure occurs. As part of the credit approval process, the restructured loans are evaluated for adequate collateral protection in determining the appropriate accrual status at the time of restructure. TDR loans may be returned to accrual status if there has been at least a six-month sustained period of repayment performance by the borrower.
Acquired loans are recorded at fair value at the date of acquisition and accordingly, no allowance for loan losses is transferred to the acquiring entity in connection with acquisition accounting. The fair values of loans with evidence of credit deterioration (purchased, credit impaired loans) are initially recorded at fair value, but thereafter accounted for differently than purchased, non-credit impaired loans. For purchased credit impaired loans, cash flows are estimated at Day 1 and discounted at a market interest rate which creates accretable yield to be recognized over the life of the loan. Contractual principal and interest payments not expected to be collected are considered non-accretable difference. Subsequent to the acquisition date, management continues to monitor cash flows on a quarterly basis, to determine the performance of each purchased credit impaired loan in comparison to management’s initial performance expectations.
Subsequent decreases to the expected cash flows will generally result in a provision for loan losses. Subsequent significant increases in cash flows result in a reversal of the provision for loan losses to the extent of prior provisions or a reclassification of amount from non-accretable difference to accretable yield, with a positive impact on the accretion of interest income in future periods.
Acquired performing loans are accounted for using the contractual cash flows method of recognizing discount accretion based on the acquired loans’ contractual cash flows. Acquired performing loans are recorded as of the acquisition date at fair value, considering credit and other risks, with no separate allowance for loan losses account. Credit losses on the acquired performing loans are estimated in future periods based on analysis of the performing portfolio. A provision for loan losses is recognized for any further credit deterioration that occurs in these loans subsequent to the acquisition date. Fair value discounts on Day 1 are accreted as interest income over the life of the loans.
|Loans and Leases Receivable, Allowance for Loan Losses Policy [Policy Text Block]
Allowance for Loan Losses
The allowance for loan losses is maintained at a level which, in management’s judgment, is adequate to absorb credit losses inherent in the loan portfolio. The amount of the allowance is based on management’s evaluation of the collectability of the loan portfolio, including the nature of the portfolio, credit concentrations, trends in historical loss experience, specific impaired loans, economic conditions, and other risks inherent in the portfolio. Allowances for impaired loans are generally determined based on collateral values or the present value of the estimated cash flows. The allowance is increased by a provision for loan losses, which is charged to expense, and reduced by charge-offs, net of recoveries. In addition, various regulatory agencies, as an integral part of their examination process, periodically review the allowance for losses on loans. Such agencies may require the Company to recognize adjustments to the allowance based on their judgments about information available to them at the time of their examination.
|Financing Receivable, Real Estate Acquired Through Foreclosure [Policy Text Block]
Foreclosed Real Estate
Foreclosed real estate includes both formally foreclosed property and in-substance foreclosed property. At the time of foreclosure, foreclosed real estate is recorded at fair value less cost to sell, which becomes the property’s new basis. Any write downs based on the asset’s fair value at date of acquisition are charged to the allowance for loan losses. After foreclosure, these assets are carried at the lower of their new cost basis or fair value less cost to sell. Costs incurred in maintaining foreclosed real estate and subsequent adjustments to the carrying amount of the property are included in other operating expenses.
|Property, Plant and Equipment, Policy [Policy Text Block]
Premises and Equipment
Premises and equipment are stated at cost less accumulated depreciation. Expenditures for additions and major improvements that significantly extend the useful lives of the assets are capitalized. Expenditures for repairs and maintenance are charged to expense as incurred. Assets which are disposed of are removed from the accounts and the resulting gains or losses are recorded in operations. Depreciation is calculated on a straight-line basis over the estimated useful lives of the related assets (3 to 39.5 years).
Leasehold improvements are amortized on a straight-line basis over the lesser of the lease terms or the estimated useful lives of the improvements.
|Lessee, Leases [Policy Text Block]
The Company leases certain office space and equipment under operating leases. Accounting Standards Update 2016-02, “Leases (Topic 842)” requires that operating leases in effect as of date of adoption, January 1, 2019 for the Company, be recognized as a liability to make lease payments and as an asset representing the right to use the asset during the lease term, or “lease liability” and “right-of-use asset”, respectively. The lease liability is measured by the present value of remaining lease payments, discounted at the Company’s incremental borrowing rate. The Company reports its right-of-use assets in other assets and its lease liabilities in other liabilities.
Certain of the leases include one or more renewal options that extend the initial lease term 1 to 5 years. The exercise of lease renewal options is typically at the Company’s sole discretion; therefore, a majority of renewals to extend lease terms are not included in the right-of-use assets and lease liabilities as they are not reasonably certain to be exercised. Renewal options are regularly evaluated and when they are reasonably certain to be exercised, are included in lease terms.
None of the Company’s leases provide an implicit rate. The Company uses its incremental collateralized borrowing rate based on the information available at the lease commencement date in determining the present value of the lease payments.
The Company has made an accounting policy election to not apply the recognition requirements in ASU 2016-02 to short-term leases. The Company has also elected to use the practical expedients allowed by the new standard as follows: 1) forego an assessment of whether any existing contracts are or contain leases, 2) forego an assessment of the classification of existing leases as to whether they are operating leases or capital leases, and 3) forego an assessment of direct costs for any existing leases.
|Goodwill and Intangible Assets, Intangible Assets, Policy [Policy Text Block]
Goodwill and Other Identifiable Intangible Assets
Other identifiable intangible assets include a core deposit intangible recorded in connection with the acquisition of Metro Bancshares, Inc. The core deposit intangible is being amortized over 7 years and the estimated useful life is periodically reviewed for reasonableness.
The Company has recorded $13.6 million of goodwill at December 31, 2019 in connection with the acquisition of Metro Bancshares, Inc. in 2015. The Company tests its goodwill for impairment annually unless interim events or circumstances make it more likely than not that an impairment loss has occurred. Impairment is defined as the amount by which the implied fair value of the goodwill is less than the goodwill’s carrying value. Impairment losses, if incurred, would be charged to operating expense. For the purposes of evaluating goodwill, the Company has determined that it operates only one reporting unit.
|Derivatives, Policy [Policy Text Block]
Derivatives and Hedging Activities
As part of its overall interest rate risk management, the Company uses derivative instruments, which can include interest rate swaps, caps, and floors. Financial Accounting Standards Board (“FASB”) ASC 815-10, Derivatives and Hedging, requires all derivative instruments to be carried at fair value on the balance sheet. This accounting standard provides special accounting provisions for derivative instruments that qualify for hedge accounting. To be eligible, the Company must specifically identify a derivative as a hedging instrument and identify the risk being hedged. The derivative instrument must be shown to meet specific requirements under this accounting standard.
The Company designates the derivative on the date the derivative contract is entered into as (1) a hedge of the fair value of a recognized asset or liability or of an unrecognized firm commitment (a “fair-value” hedge) or (2) a hedge of a forecasted transaction of the variability of cash flows to be received or paid related to a recognized asset or liability (a “cash-flow” hedge). Changes in the fair value of a derivative that is highly effective as a fair-value hedge, and that is designated and qualifies as a fair-value hedge, along with the loss or gain on the hedged asset or liability that is attributable to the hedged risk (including losses or gains on firm commitments), are recorded in current-period earnings. The effective portion of the changes in the fair value of a derivative that is highly effective and that is designated and qualifies as a cash-flow hedge is recorded in other comprehensive income, until earnings are affected by the variability of cash flows (e.g., when periodic settlements on a variable-rate asset or liability are recorded in earnings). The remaining gain or loss on the derivative, if any, in excess of the cumulative change in the present value of future cash flows of the hedged item is recognized in earnings.
The Company formally documents all relationships between hedging instruments and hedged items, as well as its risk-management objective and strategy for undertaking various hedge transactions. This process includes linking all derivatives that are designated as fair-value or cash-flow hedges to specific assets and liabilities on the balance sheet or to specific firm commitments or forecasted transactions. The Company also formally assessed, both at the hedge’s inception and on an ongoing basis (if the hedges do not qualify for short-cut accounting), whether the derivatives that are used in hedging transactions are highly effective in offsetting changes in fair values or cash flows of hedged items. When it is determined that a derivative is not highly effective as a hedge or that it has ceased to be a highly effective hedge, the Company discontinues hedge accounting prospectively, as discussed below. The Company discontinues hedge accounting prospectively when: (1) it is determined that the derivative is no longer effective in offsetting changes in the fair value or cash flows of a hedged item (including firm commitments or forecasted transactions); (2) the derivative expires or is sold, terminated, or exercised; (3) the derivative is re-designated as a hedge instrument, because it is unlikely that a forecasted transaction will occur; (4) a hedged firm commitment no longer meets the definition of a firm commitment; or (5) management determines that designation of the derivative as a hedge instrument is no longer appropriate.
When hedge accounting is discontinued because it is determined that the derivative no longer qualifies as an effective fair-value hedge, hedge accounting is discontinued prospectively and the derivative will continue to be carried on the balance sheet at its fair value with all changes in fair value being recorded in earnings but with no offsetting being recorded on the hedged item or in other comprehensive income for cash flow hedges.
The Company uses derivatives to hedge interest rate exposures associated with mortgage loans held for sale and mortgage loans in process. The Company regularly enters into derivative financial instruments in the form of forward contracts, as part of its normal asset/liability management strategies. The Company’s obligations under forward contracts consist of “best effort” commitments to deliver mortgage loans originated in the secondary market at a future date. Interest rate lock commitments related to loans that are originated for later sale are classified as derivatives. In the normal course of business, the Company regularly extends these rate lock commitments to customers during the loan origination process. The fair values of the Company’s forward contract and rate lock commitments to customers as of December 31, 2019 and 2018 were not material and have not been recorded.
|Revenue from Contract with Customer [Policy Text Block]
Accounting Standards Codification (“ASC”) Topic 606, Revenue from Contracts with Customers (“ASC 606”), provides guidance for reporting revenue from the entity’s contracts to provide goods or services to customers. The guidance requires recognition of revenue to depict the transfer of goods or services to customers in an amount that reflects the consideration that it expects to be entitled to receive in exchange for those goods or services recognized as performance obligations are satisfied.
The majority of revenue-generating transactions are excluded from the scope of ASC 606, including revenue generated from financial instruments, such as securities and loans. Revenue-generating transactions that are within the scope of ASC 606, classified within non-interest income, are described as follows:
Other non-interest income primarily includes income on bank owned life insurance contracts, letter of credit fees and gains on sale of loans held for sale, none of which are within the scope of ASC 606.
|Income Tax, Policy [Policy Text Block]
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.
The Company follows the provisions of ASC 740-10, Income Taxes. ASC 740-10 establishes a single model to address accounting for uncertain tax positions. ASC 740-10 clarifies the accounting for income taxes by prescribing a minimum recognition threshold a tax position is required to meet before being recognized in the financial statements. ASC 740-10 also provides guidance on derecognition measurement classification interest and penalties, accounting in interim periods, disclosure, and transition. ASC 740-10 provides a two-step process in the evaluation of a tax position. The first step is recognition. A Company determines whether it is more likely than not that a tax position will be sustained upon examination, including a resolution of any related appeals or litigation processes, based upon the technical merits of the position. The second step is measurement. A tax position that meets the more likely than not recognition threshold is measured at the largest amount of benefit that is greater than 50% likely of being realized upon ultimate settlement.
|Share-based Payment Arrangement [Policy Text Block]
At December 31, 2019, the Company had a stock-based compensation plan for grants of equity compensation to key employees and directors. The plan has been accounted for under the provisions of FASB ASC 718-10, Compensation – Stock Compensation with respect to employee stock options and under the provisions of FASB ASC 505-50, Equity-Based Payments to Non-Employees, with respect to non-employee stock options. Specifically, awards to employees are accounted for using the fair value-based method of accounting. Stock compensation costs are recognized prospectively for all new awards granted under the stock-based compensation plans. Compensation expense related to share options is calculated using a method that is based on the underlying assumptions of the Black-Scholes-Merton option pricing model and is charged to expense over the requisite service period (e.g. vesting period). Compensation expense related to restricted stock awards is based upon the fair value of the awards on the date of grant and is charged to earnings over the requisite service period of the award.
|Earnings Per Share, Policy [Policy Text Block]
Earnings per Common Share
Basic earnings per common share are computed by dividing net income available to common stockholders by the weighted average number of common shares outstanding during the period. Diluted earnings per common share include the dilutive effect of additional potential common shares issuable under stock options and warrants.
|Loan Commitments, Policy [Policy Text Block]
Loan Commitments and Related Financial Instruments
Financial instruments, which include credit card arrangements, commitments to make loans and standby letters of credit, are 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. Instruments such as stand-by letters of credit are considered financial guarantees in accordance with FASB ASC 460-10. The fair value of these financial guarantees is not material.
|Fair Value of Financial Instruments, Policy [Policy Text Block]
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 21. 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.
|Comprehensive Income, Policy [Policy Text Block]
Comprehensive income consists of net income and other comprehensive income. Accumulated comprehensive income, which is recognized as a separate component of equity, includes unrealized gains and losses on securities available for sale.
|Advertising Cost [Policy Text Block]
Advertising costs are expensed as incurred. Advertising expense for the years ended December 31, 2019, 2018 and 2017 was $581,000, $557,000 and $716,000, respectively. Advertising typically consists of local print media aimed at businesses that the Company targets as well as sponsorships of local events in which the Company’s clients and prospects are involved.
|New Accounting Pronouncements, Policy [Policy Text Block]
Recently Adopted Accounting Pronouncements
In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). The FASB issued this ASU to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet by lessees for those leases classified as operating leases under current U.S. GAAP and disclosing key information about leasing arrangements. The amendments in this ASU are effective for public business entities for annual periods and interim periods within those annual periods beginning after December 15, 2018. Early application of this ASU is permitted for all entities. The Company adopted the amendments in this ASU by applying the alternative transition method allowing comparative periods to not be restated and any cumulative effect adjustment to the opening balance of retained earnings to be recognized as of January 1, 2019. The Company elected the three practical expedients allowed by the amendments as follows: 1) forego an assessment of whether any existing contracts are or contain leases, 2) forego an assessment of the classification of existing leases as to whether they are operating leases or capital leases, and 3) forego an assessment of direct costs for any existing leases. Upon adoption on January 1, 2019 the Company recorded a right-of-use asset of approximately $15.3 million and lease liability of approximately $15.3 million. See Note 6 – Leases.
In March 2017, the FASB issued ASU 2017-08, Receivables – Nonrefundable Fees and Other Costs (Subtopic 310-20), Premium Amortization on Purchased Callable Debt Securities. The amendments shorten the amortization period for certain callable debt securities held at a premium. Specifically, the amendments require the premium to be amortized to the earliest call date. The amendments do not require an accounting change for securities held at a discount; the discount continues to be amortized to maturity. The amendments in this ASU were effective for public business entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. Early adoption was permitted. The amendments were to be applied on a modified retrospective basis, with a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption. The amendments in this ASU did not impact the Company’s Consolidated Financial Statements, as it has always amortized premiums to the first call date.
In June 2018, the FASB issued ASU 2018-07, Compensation – Stock Compensation (Topic 718), Improvements to Nonemployee Share-Based Payment Accounting. These amendments expand the scope of Topic 718, Compensation - Stock Compensation, which previously only included share-based payments to employees, to include share-based payments issued to nonemployees for goods or services. Consequently, the accounting for share-based payments to nonemployees and employees will be substantially aligned. The ASU supersedes Subtopic 505-50, Equity – Equity-Based Payments to Non-Employees. The amendments in this ASU were effective for public business entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. Early adoption was permitted, but no earlier than a company’s adoption date of Topic 606, Revenue from Contracts with Customers. The Company adopted this ASU effective January 1, 2019; however, the amendments did not have an impact on the Company’s Consolidated Financial Statements because it does not have any unvested stock-based payment awards currently outstanding to nonemployees.
Recent Accounting Pronouncements
In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which is essentially the final rule on use of the so-called CECL model, or current expected credit losses. Among other things, the amendments in this ASU 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. In addition, the ASU amends the accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration. The Company will adopt this guidance as of January 1, 2020. Transition to the new ASU will be through a cumulative-effect adjustment to beginning retained earnings, net of income taxes, as of January 1, 2020.
The Company’s CECL implementation team includes leadership from Accounting, Credit Administration and Risk Management. This group has worked closely with a third-party software solution vendor providing expertise in CECL modeling techniques to develop new expected credit loss estimation models. Loans with similar risk characteristics will be collectively evaluated in pools and, depending on the nature of each identified pool, the Company is currently planning to implement a discounted cash flow (“DCF”), probability of default / loss given default (“PD/LGD”) or remaining life method. The historical loss experience estimate by pool will then be adjusted by forecast factors that can be quantitatively related to the Company’s historical credit loss experience, such as national unemployment rates and gross domestic product. The Company plans to utilize a stable macroeconomic environment forecast over a one year reasonable and supportable forecast period. After the forecast period, the Company will revert to longer term average historical loss experience to estimate losses over the remaining life. The Company will also include qualitative factor adjustments, as appropriate, to account for potential limitations in the model and to fully reflect the Company’s expectations of current conditions pertinent to its loan portfolio.
Credit losses for loans that no longer share similar risk characteristics will be estimated on an individual basis. Individual evaluations will typically be performed for nonaccrual loans, loans rated substandard, and modified loans classified as troubled debt restructurings. Specific allowances will be estimated based on one of several methods, including the estimated fair value of the underlying collateral, observable market value of similar debt or the present value of expected cash flows.
The estimation methodology for credit losses on lending-related commitments will be similar to the process for estimating credit losses for loans, with the addition of a probability of draw estimate that will be applied to each commitment amount.
Based upon the nature and characteristics of our securities portfolios at the adoption date, the macroeconomic conditions and forecasts at that date, and other management judgments, the Company does not currently expect to record any allowance for credit losses on available for sale securities.
CECL parallel comparisons were performed and enhanced throughout 2019, with limited comparisons completed for the second and third quarters and a more complete parallel run for the fourth quarter. Based on the fourth quarter parallel run and the prevailing economic conditions and forecasts as of the adoption date, the Company is currently estimating a decrease in the allowance for loan losses under CECL by approximately 1% to 5%. The estimated decrease in the allowance at adoption is the result of implementing a more quantitative methodology along with the loan portfolio consisting primarily of commercial loans with generally short contractual maturities which more than offsets any increases in the consumer loan portfolios with generally longer maturities.
The Company will continue to enhance key implementation initiatives during the first quarter of 2020, including documentation and analytics, policies and procedures, and end-to-end process controls. The adoption of ASU 2016-13 is not expected to have a significant impact on our regulatory capital ratios.
In July 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement. This ASU eliminates, adds and modifies certain disclosure requirements for fair value measurements. Among the changes, entities will no longer be required to disclose the amount of and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy, however, entities will be required to disclose the range and weighted average used to develop significant unobservable inputs for Level 3 fair value measurements. ASU No. 2018-13 is effective for interim and annual reporting periods beginning after December 15, 2019; early adoption is permitted. Entities are also allowed to elect early adoption of the eliminated or modified disclosure requirements and delay adoption of the new disclosure requirements until their effective date. As ASU No. 2018-13 only revises disclosure requirements, it will not have a material impact on the Company’s Consolidated Financial Statements.
