Accounting Policies [Abstract]

Basis of Presentation and Consolidation

Basis of Presentation and Consolidation. The consolidated financial statements are prepared in conformity with U.S. generally accepted accounting principles (“GAAP”) and include the accounts of Southside Bancshares, Inc. (the “Company”), and its wholly-owned subsidiary, Southside Bank (“Southside Bank” or “the Bank”) and the nonbank subsidiaries.  All significant intercompany accounts and transactions are eliminated in consolidation.  

“Omni” refers to OmniAmerican Bancorp, Inc., a bank holding company acquired by Southside on December 17, 2014. On November 30, 2017, we acquired Diboll State Bancshares, Inc., a Texas corporation (“Diboll”) and the holding company for First Bank & Trust East Texas, a Texas banking association based in Diboll, Texas. See “Note 2 - Acquisition”.

We determine if we have a controlling financial interest in an entity by first evaluating whether the entity is a voting interest entity or a variable interest entity (“VIE”) under GAAP. Voting interest entities are entities in which the total equity investment at risk is sufficient to enable the entity to finance itself independently and provides the equity holders with the obligation to absorb losses, the right to receive residual returns and the right to make decisions about the entity’s activities. We consolidate voting interest entities in which we have all, or at least a majority of, the voting interest. As defined in applicable accounting standards, VIEs are entities that lack one or more of the characteristics of a voting interest entity. A controlling financial interest in a VIE is present when an enterprise has both the power to direct the activities of the VIE that most significantly impact the VIEs economic performance and an obligation to absorb losses or the right to receive benefits that could potentially be significant to the VIE. The enterprise with a controlling financial interest, known as the primary beneficiary, consolidates the VIE.

Use of Estimates

Use of Estimates.  In preparing consolidated financial statements in conformity with GAAP, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the balance sheet and reported amounts of revenues and expenses during the reporting period.  These estimates are subjective in nature and involve matters of judgment.  Actual results could differ from these estimates.  Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for loan losses, assumptions used in the defined benefit plan and the fair values of financial instruments.  The status of contingencies are particularly subject to change and significant assumptions used in periodic evaluation of securities for other-than-temporary impairment. Certain prior period amounts have been reclassified to conform to the current period presentation.

Segment Information

Segment Information.  Operating segments are components of a business about which separate financial information is available and that are evaluated regularly by the chief operating decision-maker in deciding how to allocate resources and assess performance. Our chief operating decision-maker uses consolidated results to make operating and strategic decisions. Therefore, we have determined that our business is conducted in one reportable segment.

Business Combinations

Business Combinations. Business combinations are accounted for using the acquisition method of accounting. Under this accounting method, the acquired company’s net assets are recorded at fair value on the date of acquisition, and the results of operations of the acquired company are combined with our results from that date forward. Costs related to the acquisition are expensed as incurred. The difference between the purchase price and the fair value of the net assets acquired (including intangible assets with finite lives) is recorded as goodwill. The accounting policy for goodwill and intangible assets is summarized in this note under the heading “Goodwill and Other Intangibles.”

Acquired loans (non-impaired and impaired) are initially measured at fair value as of the acquisition date. The fair value estimates for acquired loans are based on the estimate of expected cash flows, both principal and interest and prepayments, discounted at prevailing market interest rates. Credit discounts representing the principal losses expected over the life of the loan are also a component of the initial fair value; therefore, an allowance for loan losses is not recorded at the acquisition date.

We evaluate acquired loans for impairment in accordance with the provisions of ASC 310-30, “Loans and Debt Securities Acquired with Deteriorated Credit Quality” (“ASC 310-30”). Acquired loans are considered impaired if there is evidence of credit deterioration since origination and if it is probable at time of acquisition that all contractually required payments will not be collected. Expected cash flows at the acquisition date in excess of the fair value of the loans is referred to as the accretable yield and recorded as interest income over the life of the loans. Acquired impaired loans are not classified as nonaccrual or nonperforming as they are considered to be performing under the provisions of ASC 310-30. Subsequent to the acquisition date, increases in expected cash flows will generally result in a recovery of any previously recorded allowance for loan loss, to the extent applicable, and/or a reclassification from the nonaccretable difference to accretable yield, which will be recognized prospectively. The present value of any decreases in expected cash flows after the acquisition date will generally result in an impairment charge recorded as a provision for loan losses, resulting in an increase to the allowance for loan loss.

For acquired non-impaired loans, the difference between the acquisition date fair value and the contractual amounts due at the acquisition date represents the fair value adjustment. Fair value adjustments may be discounts (or premiums) to a loan’s cost basis and are accreted (or amortized) to interest income over the loan’s remaining contractual life using the level yield method.

Cash Equivalents

Cash Equivalents.  Cash equivalents, for purposes of reporting cash flow, include cash, amounts due from banks and federal funds sold that have an initial maturity of less than 90 days.  We maintain deposits with other institutions in amounts that exceed federal deposit insurance coverage.  Management regularly evaluates the credit risk associated with the counterparties to these transactions and believes that we are not exposed to any significant credit risks on cash and cash equivalents.

Basic and Diluted Earnings per Common Share

Basic and Diluted Earnings per Common Share.  Basic earnings per common share is based on net income divided by the weighted-average number of common shares outstanding during the period.  Diluted earnings per common share include the dilutive effect of stock options granted using the treasury stock method. 

Comprehensive Income

Comprehensive Income.  Comprehensive income includes all changes in shareholders’ equity during a period, except those resulting from transactions with shareholders.  Besides net income, other components of comprehensive income include the after tax effect of changes in the fair value of AFS securities, changes in the net unrealized loss on securities transferred to/from HTM, changes in the accumulated gain or loss on effective cash flow hedging instruments and changes in the funded status of defined benefit retirement plans.

Loans

Loans.  All loans are stated at principal outstanding net of unearned discount and other deferred expenses or fees.  Interest income on loans is recognized using the level yield method or simple interest method.  Loans receivable that management has the intent and ability to hold for the foreseeable future or until maturity or pay-off are reported at their outstanding principal adjusted for any charge-offs, the allowance for loan losses, and any unamortized deferred fees or costs on originated loans and unamortized premiums or discounts on purchased loans.  A loan is considered impaired, based on current information and events, if it is probable that we will be unable to collect the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement.  Substantially all of our impaired loans are collateral-dependent, and as such, are measured for impairment based on the fair value of the collateral.

Loans Held For Sale

Loans Held For Sale.  Loans originated and intended for sale in the secondary market are carried at the lower of aggregate cost or fair value, as determined by aggregate outstanding commitments from investors or current investor yield requirements.  Net unrealized losses are recognized through a valuation allowance by charges to income. Gains or losses on sales of mortgage loans are recognized based on the difference between the selling price and the carrying value of the related mortgage loans sold.

Loan Fees

Loan Fees.  We treat loan fees, net of direct costs, as an adjustment to the yield of the related loan over its term.

Allowance for Loan Losses

Allowance for Loan Losses.  An allowance for loan losses is provided through charges to income in the form of a provision for loan losses.  Loans which management believes are uncollectible are charged against this account with subsequent recoveries, if any, credited to the account.  The amount of the allowance for loan losses is determined by management’s evaluation of the quality and inherent risks in the loan portfolio, economic conditions and other factors which warrant current recognition.

Nonaccrual Loans

Nonaccrual Loans.  A loan is placed on nonaccrual when principal or interest is contractually past due 90 days or more unless, in the determination of management, the principal and interest on the loan are well collateralized and in the process of collection.  In addition, a loan is placed on nonaccrual when, in the opinion of management, the future collectability of interest and principal is not expected.  When classified as nonaccrual, accrued interest receivable on the loan is reversed and the future accrual of interest is suspended.  Payments of contractual interest are recognized as income only to the extent that full recovery of the principal balance of the loan is reasonably certain.

Other Real Estate Owned

Other Real Estate Owned and Foreclosed Assets.  Other Real Estate Owned (“OREO”) includes real estate acquired in full or partial settlement of loan obligations.  OREO is initially carried at the fair value of the collateral net of estimated selling costs.  Prior to foreclosure, the recorded amount of the loan is written down, if necessary, to the appraised fair value of the real estate to be acquired, less selling costs, by charging the allowance for loan losses.  Any subsequent reduction in fair value net of estimated selling costs is charged to noninterest expense. Costs of maintaining and operating foreclosed properties are expensed as incurred and included in other expense in our income statement.  Expenditures to complete or improve foreclosed properties are capitalized only if expected to be recovered; otherwise, they are expensed.

Foreclosed Assets

Other foreclosed assets are held for sale and are initially recorded at fair value less estimated selling costs at the date of foreclosure, by charging the allowance for loan losses. Subsequent to foreclosure, valuations are periodically performed by management and the assets are carried at the lower of carrying amount or fair value less costs to sell. Foreclosed assets are included in other assets in the accompanying consolidated balance sheets. Expenses from operations and changes in the valuation allowance are included in noninterest expense.

Securities

Securities.  Available for Sale (“AFS”).  Debt securities that will be held for indefinite periods of time, including securities that may be sold in response to changes in market interest or prepayment rates, needs for liquidity and changes in the availability of and the yield on alternative investments are classified as AFS.  These assets are carried at fair value with unrealized gains and losses reported as a separate component of accumulated other comprehensive income (“AOCI”), net of tax.  Fair value is determined using quoted market prices as of the close of business on the balance sheet date.  If quoted market prices are not available, fair values are based on quoted market prices for similar securities or estimates from independent pricing services. Securities that are hedged with qualifying derivatives are carried at fair value with the change in fair value on both the hedged instrument and the securities recorded in interest income in the consolidated statements of income.

Held to Maturity (“HTM”). Debt securities that management has the positive intent and ability to hold until maturity are classified as HTM and are carried at their remaining unpaid principal balance, net of unamortized premiums or unaccreted discounts.

Prior to January 1, 2019, premiums were amortized and discounts were accreted to maturity, or in the case of mortgage-backed securities (“MBS”), over the estimated life of the security, using the level yield interest method.  Effective January 1, 2019, premium callable securities will be amortized to the earliest call date and securities purchased at a discount will be accreted to maturity.

Unrealized gains and losses on AFS securities are excluded from earnings and reported net of tax in AOCI until realized.  Declines in the fair value of AFS or HTM securities below their cost that are deemed to be other-than-temporary are reflected in earnings as a realized loss if there is no ability or intent to hold to recovery.  If the Company does not intend to sell and will not be required to sell prior to recovery of its amortized cost basis, only the credit component of the impairment is reflected in earnings as a realized loss with the noncredit portion recognized in other comprehensive income. In estimating other-than-temporary impairment losses, we consider (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) our intent and ability to retain our investment in the issuer for a period of time sufficient to allow for any anticipated recovery in fair value.  Gains and losses on the sale of securities are recorded in the month of the trade date and are determined using the specific identification method.

Equity Investments. Beginning January 1, 2018, upon adoption of ASU 2016-01, equity investments with readily determinable fair values are stated at fair value with the unrealized gains and losses reported in other noninterest income in the consolidated statements of income. For periods prior to January 1, 2018, certain equity investments were classified as AFS and stated at fair value with unrealized gains and losses reported as a separate component of AOCI, net of tax. Equity investments without readily determinable fair values are recorded at cost less impairment, if any.

Securities with Limited Marketability

Securities with Limited Marketability. Securities with limited marketability, such as stock in the FHLB, are carried at cost and assessed for other-than-temporary impairment.

Premises and Equipment

Premises and Equipment.  Land is carried at cost. Bank premises and equipment are stated at cost, net of accumulated depreciation.  Depreciation is computed on a straight line basis over the estimated useful lives of the related assets.  Useful lives are estimated to be 15 to 40 years for premises and 3 to 10 years for equipment.  Leasehold improvements are generally depreciated over the lesser of the term of the respective leases or the estimated useful lives of the improvements.  Maintenance and repairs are charged to expense as incurred while major improvements and replacements are capitalized.

Bank Owned Life Insurance

Bank-Owned Life Insurance.  The Company has purchased life insurance policies on certain key executives. 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. Changes in the net cash surrender value of the policies, as well as insurance proceeds received are reflected in noninterest income on the consolidated statements of income and are not subject to income taxes.

Goodwill and Other Intangibles

Goodwill and Other Intangibles.  Other intangible assets consist primarily of core deposits and trust relationship intangibles. Intangible assets with definite useful lives are amortized on an accelerated basis over their estimated life. Goodwill and intangible assets that have indefinite useful lives are subject to at least an annual impairment test and more frequently if a triggering event occurs. If any such impairment is determined, a write-down is recorded.

Repurchase Agreements

Repurchase Agreements.  We sell certain securities under agreements to repurchase.  The agreements are treated as collateralized financing transactions and the obligations to repurchase securities sold are reflected as a liability in the accompanying consolidated balance sheets.  The dollar amount of the securities underlying the agreements remains in the asset account.  We determine the type of securities to pledge.  Generally we pledge U.S. agency MBS.

Derivative Financial Instruments and Hedging Activities

Derivative Financial Instruments and Hedging Activities. Derivative financial instruments are carried on the consolidated balance sheets as other assets or other liabilities, as applicable, at estimated fair value. The accounting for changes in the fair value (i.e., gains or losses) of a derivative financial instrument is determined by whether it has been designated and qualifies as part of a hedging relationship and, further, by the type of hedging relationship. We present derivative financial instruments at fair value in the consolidated balance sheets on a net basis when a right of offset exists, based on transactions with a single counterparty and any cash collateral paid to and/or received from that counterparty for derivative contracts that are subject to legally enforceable master netting arrangements.

For derivative instruments that are designated and qualify as cash flow hedges (i.e., hedging the exposure to variability in expected future cash flows that is attributable to a particular risk), the effective portion of the gain or loss on the derivative instrument is reported as a component of other comprehensive income and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. The remaining gain or loss on the derivative instrument in excess of the cumulative change in the present value of future cash flows of the hedged item (i.e., the ineffective portion), if any, is recognized in current earnings during the period of change. For derivative instruments not designated as hedging instruments, the gain or loss is recognized in current earnings during the period of change.

During the three months ended June 30, 2018, we entered into partial term fair value hedges, as allowed under the recently adopted ASU 2017-12, for certain of our fixed rate callable available for sale municipal securities. These partial term hedges of selected cash flows covering the time periods to the call dates of the hedged securities are expected to be effective in offsetting changes in the fair value of the hedged securities. Interest rate swaps designated as partial-term fair value hedges are utilized to mitigate the effect of changing interest rates on the hedged securities. The hedging strategy converts a portion of the fixed interest rates on the securities to LIBOR-based variable interest rates.

For derivatives designated as hedging instruments at inception, statistical regression analysis is used at inception and for each reporting period thereafter to assess whether the derivative used has been and is expected to be highly effective in offsetting changes in the fair value or cash flows of the hedged item. All components of each derivative instrument’s gain or loss are included in the assessment of hedge effectiveness. Net hedge ineffectiveness is recorded in “other noninterest income” on the consolidated statements of income.

Terminated Derivative Financial Instruments

Terminated Derivative Financial Instruments. In accordance with ASC Topic 815, if a hedging item is terminated prior to maturity for a cash settlement, the existing gain or loss within AOCI will continue to be reclassified into earnings during the period or periods in which the hedged forecasted transaction affects earnings unless it is probable that the forecasted transaction will not occur by the end of the originally specified time period. If the forecasted transaction is deemed probable to not occur, the derivative gain or loss reported in AOCI shall be reclassified into earnings immediately. During the first quarter of 2017, we terminated two interest rate swap contracts designated as cash flow hedges. At the time of termination, we determined that the underlying hedged forecasted transactions were still probable of occurring. These transactions are reevaluated on a monthly basis to determine if the hedged forecasted transactions are still probable of occurring. If at a subsequent evaluation it is determined that the transactions will not occur, any related gains or losses recorded in AOCI are immediately recognized in earnings.

Revenue Recognition

Revenue Recognition. Our revenue consists of net interest income on financial assets and financial liabilities and noninterest income.  The classifications of our revenue are presented in the consolidated statements of income. On January 1, 2018, we adopted ASU 2014-09, “Revenue from Contracts with Customers (Topic 606)” using the modified retrospective method. The revenue recognition principle in ASU 2014-09 is that an entity should recognize revenue to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services.

ASU 2014-09 permits an entity to recognize the incremental costs of obtaining a contract as an expense when incurred if the amortization period of the asset would have been one year or less. We generally expense sales commissions when incurred because the amortization period is within one year or less. These costs are recorded within salaries and employee benefits on the consolidated statements of income.

Revenue is recognized when obligations under the terms of a contract with our customer are satisfied; generally this occurs with the transfer of control of goods or services. Under ASU 2014-09’s practical expedient to recognize revenue equal to the amounts for which we have a right to invoice, revenue is measured as the amount of consideration we expect to receive in exchange for the transfer of those goods or services.

The following summarizes our revenue recognition policies as they relate to revenue from contracts with customers under ASU 2014-09:

• Deposit services. Service charges on deposit accounts include fees for banking services provided, overdrafts and non-sufficient funds. Revenue is generally recognized in accordance with published deposit account agreements for retail accounts or contractual agreements for commercial accounts. Our deposit services also include our ATM and debit card interchange revenue that is presented net of the associated costs. Interchange revenue is generated by our deposit customers’ usage and volume of activity. Interchange rates are not controlled by the Company, which effectively acts as processor that collects and remits payments associated with customer debit card transactions.

• Trust income. Trust income includes fees and commissions from investment management, administrative and advisory services primarily for individuals, and to a lesser extent, partnerships and corporations. Revenue is recognized on an accrual basis at the time the services are performed and when we have a right to invoice and are based on either the market value of the assets managed or the services provided.

• Brokerage services. Brokerage services income includes fees and commissions charged when we arrange for another party to transfer brokerage services to a customer. The fees and commissions under this agent relationship are based upon stated fee schedules based upon the type of transaction, volume and value of the services provided.

• Other noninterest income. Other noninterest income includes among other things, merchant services income. Merchant services revenue is derived from third party vendors that process credit card transactions on behalf of our merchant customers. Merchant services revenue is primarily comprised of residual fee income based on the referred merchant’s processing volumes and/or margin.

Income Taxes

Income Taxes.  We file a consolidated federal income tax return.  Income tax expense represents the taxes expected to be paid or returned for current year taxes adjusted for the change in deferred tax assets and liabilities. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases.  Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled.  The effect on deferred tax assets and liabilities of changes in tax rates is recognized in income in the period the change occurs. Uncertain tax positions arise when it is more likely than not that the tax position taken will be sustained upon examination by the appropriate tax authority. Any income tax benefit as well as penalties and interest related to income tax expense are recorded as a component of income tax expense.

Fair Value of Financial Instruments

Fair Value of Financial Instruments.  Fair values of financial instruments are estimated using relevant market information and other assumptions.  Fair value estimates involve uncertainties and matters of significant judgment.  In cases where quoted market prices are not available, fair values are based on estimates using present value or other estimation techniques.  Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows.

Defined Benefit Pension Plan

Defined Benefit Pension Plan.  Defined benefit pension obligations and the annual pension costs are determined by independent actuaries and through the use of a number of assumptions that are reviewed by management. These assumptions include a compensation rate increase, a discount rate used to determine the current benefit obligation and a long-term expected rate of return on plan assets. Net periodic defined benefit pension expense includes service cost, interest cost based on the assumed discount rate, an expected return on plan assets, amortization of prior service cost and amortization of net actuarial gains or losses. Prior service costs include the impact of plan amendments on the liabilities and are amortized over the future service periods of active employees expected to receive benefits under the plan. Actuarial gains and losses result from experience different from that assumed and from changes in assumptions. Amortization of actuarial gains and losses is included as a component of net periodic defined benefit pension cost. The service cost component is recorded on our consolidated income statement as salaries and employee benefits in noninterest expense while all other components other than service cost are recorded in other noninterest expense.

Share-Based Awards

Share-Based Awards.  Share-based compensation transactions are recognized as compensation cost in the income statement based on their fair values on the date of the grant and recorded over the vesting period.

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.

Trust Assets

Wealth Management and Trust Assets.  Our wealth management and trust assets, other than cash on deposit at Southside Bank, are not included in the accompanying financial statements, because they are not our assets.

Accounting Pronouncements

Accounting Pronouncements:

In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842).” ASU 2016-02 requires most leases to be recognized on the balance sheet and requires enhanced disclosures. Consistent with legacy GAAP, the recognition, measurement and presentation of expenses and cash flows arising from a lease by a lessee primarily will depend on its classification as a finance or operating lease. However, unlike legacy GAAP which requires only capital leases to be recognized on the balance sheet, the new ASU 2016-02 will require both finance (formerly known as “capital”) and operating leases to be recognized on the balance sheet. ASU 2016-02 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. The guidance originally required companies to apply the requirements in the year of adoption using a modified retrospective approach beginning in the earliest period presented; however, in July 2018, the FASB issued ASU 2018-11 “Leases (Topic 842): Targeted Improvements,” which provides lessees the option to apply the new leasing standard by recognizing a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. We adopted ASU 2016-02 on January 1, 2019, the effective date of the guidance, using the cumulative-effect adjustment option and did not revise comparative period information or disclosure. We also elected certain optional practical expedients including the hindsight practical expedient under which we considered the actual outcomes of lease renewals and terminations when measuring the lease term. Our operating leases relate primarily to bank branches and office space. In conjunction with the adoption, on January 1, 2019, we recognized lease liabilities of $10.1 million and related lease assets of $9.8 million on our balance sheet. The difference between the lease assets and lease liabilities primarily consists of deferred rent liabilities reclassified upon adoption to reduce the measurement of the lease assets. The adoption of the new standard will result in additional quantitative and qualitative disclosures.

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 introduces an approach based on expected losses to estimate credit losses on certain types of financial instruments. ASU 2016-13 also modifies the impairment model for AFS debt securities and provides for a simplified accounting model for purchased financial assets with credit deterioration since their origination. ASU 2016-13 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early adoption is permitted for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. The guidance requires companies to apply the requirements in the year of adoption through a cumulative-effect adjustment with some aspects of the update requiring a prospective transition approach. We are currently evaluating the potential impact of the pending adoption of ASU 2016-13 on our consolidated financial statements. We plan to adopt on January 1, 2020, the effective date. We have developed a project plan and have assigned a project team to complete the analysis needed to implement the guidance. We are also currently working with a third party vendor solution to assist with the application of ASU 2016-13. The team is currently completing the data collection and anticipates running parallel models during 2019.

In January 2017, the FASB issued ASU 2017-04, “Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment.” ASU 2017-04 is intended to simplify goodwill impairment testing by eliminating the second step of the analysis which requires the calculation of the implied fair value of goodwill to measure a goodwill impairment charge. The update requires entities to compare the fair value of a reporting unit with its carrying amount and recognize an impairment charge for any amount by which the carrying amount exceeds the reporting unit’s fair value, to the extent that the loss recognized does not exceed the amount of goodwill allocated to that reporting unit. ASU 2017-04 is effective for annual and interim goodwill impairment tests performed in periods beginning after December 15, 2019. Early adoption is permitted for annual and interim goodwill impairment testing dates after January 1, 2017. The guidance requires companies to apply the requirements prospectively in the year of adoption. ASU 2017-04 is not expected to have a significant impact on our consolidated financial statements.

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.” Under current GAAP, premiums on callable debt securities are generally amortized over the contractual life of the security. ASU 2017-08 requires the premium on callable debt securities to be amortized to the earliest call date. If the debt security is not called at the earliest call date, the holder of the debt security would be required to reset the effective yield on the debt security based on the payment terms required by the debt security. ASU 2017-08 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. The guidance requires companies to apply the requirements on a modified retrospective basis through a cumulative-effect adjustment directly to retained earnings as of the beginning of the period of adoption. We adopted the new standard on January 1, 2019, the effective date of the guidance, and recognized a cumulative-effect adjustment to reduce retained earnings by $16.5 million, before tax.
