Accounting Policies [Abstract]
Basis of Presentation and Significant Accounting Policies	ALTABANCORP TM NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS Note 1 — Basis of Presentation and Significant Accounting Policies Nature of operations and basis of consolidation — Altabancorp TM (“ALTA” or the “Company”) is a Utah corporation headquartered in American Fork, Utah. The Company operates all business activities through its wholly-owned banking subsidiary, Altabank TM (the “Bank”), which was organized in 1913. Altabank TM is a Utah state-chartered bank. Altabank TM operates under the jurisdiction of the Utah Department of Financial Institutions (“UDFI”), and its deposits are insured by the Federal Deposit Insurance Corporation (“FDIC”). Altabank TM is not a member of the Federal Reserve System; however, ALTA is operated as a bank holding company under the Federal Bank Holding Company Act of 1956 and is the sole shareholder of Altabank TM . Both ALTA and Altabank TM are subject to periodic examination by all of the applicable federal and state regulatory agencies and file periodic reports and other information with such agencies. The Company considers Altabank TM to be its sole operating segment. Altabank TM TM TM TM TM The accompanying unaudited interim consolidated financial statements include the accounts of the Company together with its subsidiary Bank. All intercompany transactions and balances have been eliminated. These unaudited interim consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (GAAP) for interim financial information and in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X as promulgated by the Securities and Exchange Commission (SEC). In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation of the financial position and results of operations for the periods presented have been included. Certain information and disclosures normally included in annual financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to the rules and regulations of the SEC and the accounting standards for interim financial statements. Use of estimates — The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires management to make estimates and assumptions. These estimates and assumptions affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reported period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for credit losses (“ACL”), the determination of the fair value of certain financial instruments, the valuation of real estate acquired through foreclosure, deferred income tax assets, and share-based compensation. Reclassifications — Certain reclassifications have been made to the 2019 Consolidated Financial Statements and/or schedules to conform to the 2020 presentation. These reclassifications may have affected certain ratios for the prior periods. The effect of these reclassifications is considered immaterial. Business combinations — Business combinations are accounted for using the acquisition method of accounting and, accordingly, assets acquired and liabilities assumed, both tangible and intangible, and consideration exchanged are recorded at fair value on the acquisition date. The excess purchase consideration over fair value of net assets acquired is recorded as goodwill. Expenses incurred in connection with a business combination are expensed as incurred. Changes in deferred tax asset valuation allowances related to acquired tax uncertainties are recognized in net income after the measurement period. Note 1 — Basis of Presentation and Significant Accounting Policies – Continued Cash and cash equivalents — Cash and cash equivalents consist of cash on hand, amounts due from banks, interest bearing deposits, and federal funds sold, all of which have original maturities of three months or less. The Company places its cash with high credit quality institutions. The amounts on deposit fluctuate and, at times, exceed the insured limit by the FDIC, which potentially subjects the Company to credit risk. Investment securities — Investment securities are classified as held to maturity (“HTM”) when the Company has the positive intent and ability to hold the securities to maturity. Investment securities are classified as available for sale (“AFS”) when the Company has the intent of holding the security for an indefinite period of time, but not necessarily to maturity. The Company determines the appropriate classification at the time of purchase, and periodically thereafter. Investment securities classified as HTM are carried at amortized cost. Investment securities classified as AFS are reported at fair value. As the fair value of AFS securities changes, the changes are reported (net of tax, if applicable) in comprehensive income and as an element of accumulated other comprehensive income/loss (“AOCI”) in shareholder’s equity. Interest income includes amortization of purchase premium or discount. Premiums and discounts on securities are generally amortized on the level-yield method without anticipating prepayments, except for callable debt securities. Premiums on callable debt securities are amortized to the earliest call date. When AFS securities, specifically identified, are sold, the unrealized gain or loss is reclassified from AOCI to non-interest income. A debt security is placed on nonaccrual status at the time any principal or interest payments become greater than 90 days delinquent. Delinquent interest accrued but not received for a security placed on nonaccrual is reversed against interest income. The Company did not have any accrued interest reversed against interest income for the six months ended June 30, 2020. Allowance for credit losses – AFS securities —For AFS debt securities in an unrealized loss position, management assesses whether the Company intends to sell or it is more likely than not that the Company will be required to sell the security before recovery of its amortized cost basis. If either criterion regarding intent or requirement to sell is met, the security’s amortized cost basis is written down to the fair value through non-interest income. For AFS debt securities that do not meet the aforementioned criteria, management evaluates whether the decline in fair value has resulted from credit losses or other factors. In making this assessment, management considers the extent to which the fair value is less than amortized cost, any changes to the rating of the security by a rating agency, and any adverse conditions specifically related to the security, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security is compared to the amortized cost basis of the security. If the present value of cash flows expected to be collected is less than the amortized cost basis, a credit loss exists and an allowance for credit losses is recorded for the credit loss, which is limited by the amount that the fair value is less than the amortized cost basis. Any impairment that has not been recorded through an allowance for credit losses is recognized in AOCI. Changes in the allowance for credit losses are recorded as a Provision for Credit Losses (“PCL”). Losses are charged against the allowance when management believes the uncollectibility of an AFS security is confirmed or when either of the criterion regarding intent or requirement to sell is met. Non-marketable equity securities — Non-marketable equity securities primarily consist of Federal Home Loan Bank (“FHLB”) stock. FHLB stock is restricted because such stock may only be sold to FHLB at its par value. Due to the restrictive terms, and the lack of a readily determinable market value, FHLB stock is carried at cost. The investments in FHLB stock are required investments related to the Bank’s borrowings from FHLB. FHLB obtains its funding primarily through issuance of consolidated obligations of the FHLB system. The U.S. government does not guarantee these obligations, and each of the regional FHLBs is jointly and severally liable for repayment of each other’s debt. Note 1 — Basis of Presentation and Significant Accounting Policies – Continued Loans held for sale —Single-family residential mortgage loans originated with the intent to be sold in the secondary market are considered held for sale. Loans with best effort delivery commitments are carried at the lower of aggregate cost or estimated fair value. Loans under mandatory delivery commitments are carried at fair value in order to match changes in the value of the loans with the value of the economic hedges on the loans. Fair values for loans held for sale are determined by comparing actual loan rates to current secondary market prices for similar loans. Net unrealized losses on loans held for sale that are carried at lower of cost or market are recognized through the valuation allowance by charges to income. Mortgage loans held for sale are generally sold with the mortgage servicing rights. 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. Substantially all of the residential mortgage loans originated are sold to larger financial institutions. Loans held for investment — Loans that management has the intent and ability to hold for the foreseeable future or until maturity or pay-off are reported at amortized cost, net of the allowance for credit losses. Amortized cost includes the principal balance outstanding, net of purchase premiums and discounts, deferred loan fees and costs. Accrued interest is reported as a separate line item on the unaudited consolidated balance sheets. Interest income is accrued on the unpaid principal balance. Loan origination fees, net of certain direct origination costs, are deferred and recognized in interest income using the effective interest method without anticipating prepayments. Interest income on mortgage and commercial loans is discontinued and placed on nonaccrual status at the time the loan is 90 days delinquent, unless the loan is well secured and in process of collection. Mortgage loans are charged off at 180 days past due, and commercial loan are charged-off to the extent principal or interest is deemed uncollectible. Consumer and credit card loans continue to accrue interest until they are charged-off no later than 120 days past due unless the loan is in the process of collection. Past-due status is based on the contractual terms of the loan. In all cases, loans are placed on nonaccrual or charge-off at an earlier date if collection of principal or interest is considered doubtful. All interest accrued but not received for loans placed on nonaccrual is reversed against interest income. Interest received on such loans is accounted for on the cash-basis or cost-recovery method, until qualifying for return to accrual. Under the cost-recovery method, interest income is not recognized until the loan balance is reduced to zero. Under the cash-basis method, interest income is recorded when the payment is received in cash. Loans are returned to accrual status when all principal and interest amounts contractually due are brought current and future payments are reasonably assured. Troubled debt restructurings (“TDR”) —A loan for which the terms have been modified resulting in a concession, and for which the borrower is experiencing financial difficulties, is considered to be a TDR. TDRs are then evaluated to determine if the TDR loan has estimated credit losses using the same methodology used for other individually evaluated loans as described in the next section. With the recent COVID-19 pandemic, the number of loans that have had loan payments deferred has significantly increased. In accordance with regulatory guidance, to the extent that the borrower was not experiencing financial difficulties prior to the pandemic, such modifications have not been classified as TDRs. Individually evaluated loans — The Company considers loans individually evaluated when, based on current information and events, 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. Such loans are generally classified as Substandard or Doubtful loans (see Note 3). Individually evaluated loans are measured based on the present value of expected future cash flows discounted at the loan’s effective interest rate, the loan’s observable market price, or the fair value of the collateral, adjusted for selling costs, if the loan is collateral dependent. Changes in these values are recorded to the ACL through the PCL. Factors considered by management in determining estimated credit losses include payment status, collateral value and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as individually evaluated. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record and the amount of the shortfall in relation to the principal and interest owed. Note 1 — Basis of Presentation and Significant Accounting Policies – Continued Acquired loans – Loans acquired through purchase or through a business combination are recorded at their fair value at the acquisition date, including estimates of current expected credit losses. Some acquired loans have experienced more than insignificant credit deterioration since origination. Such loans are defined as Purchased Credit Deteriorated (“PCD”). The Company makes the determination if a loan is PCD by considering past due and/or nonaccrual status, prior designation of a troubled debt restructuring, or other factors that may suggest the Company will not be able to collect all contractual payments due. Subsequent to acquisition, the amount of expected credit losses as of the acquisition date is added to the purchase price of PCD loans with an offsetting entry to ACL. Any difference between the unpaid principal balance and the amortized cost basis of the PCD loan as of the acquisition date is the non-credit discount or premium. The non-credit discount recorded at acquisition is amortized or accreted into interest income over the remaining life of the PCD loan on an effective interest method. To the extent that management changes the Company’s estimate of expected credit losses on PCD loans, the ACL will be increased or decreased with a corresponding entry to PCL. Some acquired loans may not have experienced more than insignificant credit deterioration since origination. Such loans are defined as Purchased non-Credit Deteriorated (“Non-PCD”) loans. Non-PCD loans are also recorded at fair value at the time of acquisition, including estimates of current expected credit losses. However, any current expected credit losses estimated as of the acquisition date are not added to the purchase price with an offsetting entry to ACL, but rather such estimate is included in the difference between the unpaid principal balance and the amortized cost basis of the Non-PCD loan. This credit and non-credit discount is amortized or accreted into interest income over the remaining life of the Non-PCD loan on an effective interest method. In addition, an allowance for credit losses is determined for Non-PCD loans using the same methodology as loans held for investment with an offset recorded to PCL. An acquired loan previously classified by the seller as a TDR is no longer classified as such at the date of acquisition. Past due status is reported based on contractual payment status. Changes to the ACL for acquired loans are recorded through PCL after adoption. Allowance for credit losses – Loans — Credit risk is inherent in the business of extending loans and leases to borrowers. Normally, this credit risk is addressed through a valuation allowance termed allowance for credit losses. The ACL represents management’s estimate of current expected credit losses (“CECL”) inherent in the loan portfolio at each balance sheet date. Netted against the outstanding loan balance, this ACL reduces the balance to the Company’s estimate of what will be collected from borrowers. The ACL is established through charges to current period earnings by recording a PCL. When losses become specifically identifiable and quantifiable, the loan balance is reduced through recording a charge-off against the ACL. Should payments be received on a charged-off loan, the payment is credited to the ACL as a recovery. Management estimates the ACL using relevant available information, from internal and external sources, relating to past events, current conditions, and reasonable and supportable forecasts. Historical credit loss experience, either internal or peer information, provides the basis for the estimation of expected credit losses. Adjustments to historical loss information are made, using qualitative factors, when management expects current conditions and reasonable and supportable forecasts to differ from the conditions that existed for the period over which historical information was evaluated. Management must exercise significant judgment when evaluating the effect of qualitative factors on the amount of the ACL because data may not be reasonably available or directly applicable for management to determine the precise impact of a factor on the collectability of the loan portfolio as of the evaluation date. Management considers qualitative or environmental factors that are likely to cause estimated credit losses associated with our existing portfolio to differ from historical loss experience, including but not limited to: i) changes in lending policies and procedures; ii) changes in underwriting standards and collection, charge-off, and recovery practices not considered elsewhere in estimating credit losses; iii) changes in international, national, regional, and local economic and business conditions and developments that affect the collectability of the portfolio, including the condition of various market segments; iv) changes in the nature and volume of the portfolio and in the terms of loans; v) changes in the experience, ability, and depth of lending management and other relevant staff; vi) changes in the volume and severity of past due loans, the volume of nonaccrual loans, and the volume and severity of adversely classified or graded loans; vii) changes in the quality of the institution’s loan review system; viii) changes in the value of underlying collateral for collateral-dependent loans; ix) the existence and effect of any concentrations of credit, and changes in the level of such concentrations; and, x) the effect of other external factors such as competition and legal and regulatory requirements on the level of estimated credit losses in the institution’s existing portfolio. This evaluation is inherently subjective, as it requires estimates that are susceptible to significant revision, as more information becomes available. Note 1 — Basis of Presentation and Significant Accounting Policies – Continued The Company used the weighted average remaining maturity (or “WARM”) approach, adjusted for prepayments, to calculate CECL at June 30, 2020 and segmented its loan portfolio into seventeen loan segments based on similar risk characteristics. Management may change the approach used to calculated current expected credit losses or loan segments from time-to-time as the Company improves credit loss estimation techniques. The Company has elected to exclude accrued interest receivable from its calculation of the ACL. Off-balance sheet credit related financial instruments — In the ordinary course of business, the Company has entered into commitments to extend credit, including commitments under credit card arrangements, commercial letters of credit, and standby letters of credit. Such financial instruments are recorded when they are funded. Allowance for credit losses on off-balance sheet credit exposures — The Company estimates expected credit losses on off-balance sheet credit exposures using the same CECL historical loss rates applied to loans held for investment over the contractual period in which the Company is exposed to credit risk through a contractual obligation to extend credit, unless that obligation is unconditionally cancellable by the Company, adjusted for funding factors. The allowance for credit losses on off-balance sheet credit exposures is reported in other liabilities on the unaudited consolidated balance sheets with an offset to other non-interest expense. The estimate of CECL includes consideration of the likelihood that funding will occur and an estimate of expected credit losses on commitments expected to be funded over their estimated life. Premises and equipment — Land is carried at cost. Premises and equipment are carried at cost, net of accumulated depreciation and amortization. Depreciation and amortization expense is computed using the straight-line method based on the estimated useful lives of the related assets below: Building and building improvements 15 to 40 years Leasehold improvements 3 to 15 years Furniture and equipment 3 to 15 years Computers, software and equipment 3 to 5 years Maintenance and repairs are expensed as incurred while major additions and improvements are capitalized. Bank-owned life insurance (“BOLI”) — The Bank has purchased life insurance policies. These policies provide protection against the adverse financial effects that could result from the death of a key employee and provide tax-exempt income to offset expenses associated with the plans. It is the Bank’s intent to hold these policies as a long-term investment; however, there may be an income tax impact if the Bank chooses to surrender certain policies. Although the lives of individual current or former management-level employees are insured, the Bank is the owner and sole or partial beneficiary. BOLI is carried at the cash surrender value (“CSV”) of the underlying insurance contract. Changes in the CSV and any death benefits received in excess of the CSV are recognized as non-interest income. Goodwill — Goodwill represents the excess of the purchase considerations paid over the fair value of the assets acquired, net of the fair values of liabilities assumed in a business combination and is not amortized but is reviewed annually, or more frequently as current circumstances and conditions warrant, for impairment. An assessment of qualitative factors is completed to determine if it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If the qualitative analysis concludes that further analysis is required, then a quantitative impairment test would be completed. The quantitative goodwill impairment compares the reporting unit's estimated fair values, including goodwill, to its carrying amount. If the carrying amount exceeds its reporting unit’s fair value, then an impairment loss would be recognized as a charge to earnings but is limited by the amount of goodwill allocated to that reporting unit. Other intangible assets — Other intangible assets consist primarily of core deposit intangibles (“CDI”), which are amounts recorded in business combinations or deposit purchase transactions related to the value of transaction-related deposits and the value of the client relationships associated with the deposits. Core deposit intangibles are amortized over the estimated useful life of such deposits. These assets are reviewed at least annually for events or circumstances that could affect their recoverability. These events could include loss of the underlying core deposits, increased competition or adverse changes in the economy. To the extent other identifiable intangible assets are deemed unrecoverable; impairment losses are recorded in other non-interest expense to reduce the carrying amount of the assets. Note 1 — Basis of Presentation and Significant Accounting Policies – Continued Mortgage and other servicing rights — Mortgage and other servicing rights are recognized as separate assets when rights are acquired through purchase of such rights or through the sale of loans. Generally, purchased servicing rights are capitalized at the cost to acquire the rights. For loans sold, the fair value of the servicing rights are estimated and capitalized. Fair value is based on market prices for comparable servicing rights contracts. Capitalized servicing rights are reported in other assets and are amortized into non-interest income in proportion to, and over the period of, the estimated future net servicing income of the underlying financial assets. Other real estate owned — Assets acquired through, or in lieu of, loan foreclosure are held for sale and are initially recorded at the lower of the carrying amount of the foreclosed loan or the fair value of the foreclosed asset, less costs to sell, at the date of foreclosure. Subsequent to foreclosure, management periodically performs valuations and the assets are carried at the lower of carrying amount or fair value, less selling costs. Revenues and expenses from operations and changes in the valuation allowance are included in other real estate owned expense. Transfers of financial assets — Transfers of financial assets are accounted for as sales when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when (1) the assets have been isolated from the Company, (2) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and (3) the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity. Income taxes — Deferred income tax assets and deferred income tax liabilities represent the tax effect of temporary differences between financial reporting and tax reporting measured at enacted tax rates in effect for the year in which the differences are expected to reverse. The Company recognizes only the impact of tax positions that, based on their technical merits, are more likely than not to be sustained upon an audit by the taxing authority. Developing the provision for income taxes, including the effective tax rate and analysis of potential tax exposure items, if any, requires significant judgment and expertise in federal and state income tax laws, regulations and strategies, including the determination of deferred income tax assets and liabilities and any estimated valuation allowances deemed necessary to value deferred income tax assets. Judgments and tax strategies are subject to audit by various taxing authorities. While the Company believes it has no significant uncertain income tax positions in the consolidated financial statements, adverse determinations by these taxing authorities could have a material adverse effect on the consolidated financial positions, result of operations, or cash flows. Share-based compensation plans — The fair value of incentive share-based awards is recorded as compensation expense over the vesting period of the award. Compensation expense for stock options is estimated at the date of grant using the Black-Scholes option-pricing model. Compensation expense for RSUs is based on the fair value of the Company’s common shares at the date of grant. RSU awards generally vest in thirds over three years from date of grant. Earnings per share — Basic earnings per common share represents income available to common shareholders divided by the weighted-average number of common shares outstanding during the period. Diluted earnings per share reflect additional common shares that would have been outstanding if dilutive potential common shares had been issued. Potential common shares include shares that may be issued by the Company for outstanding stock options determined using the treasury stock method and for all outstanding RSUs. Note 1 — Basis of Presentation and Significant Accounting Policies – Continued Earnings per common share have been computed based on the following: Three Months Ended Six Months Ended June 30, June 30, (Dollars in thousands, except share and per share data) 2020 2019 2020 2019 Numerator Net income $ 10,338 $ 10,989 $ 21,111 $ 21,494 Denominator Weighted-average number of common shares outstanding 18,789,561 18,805,760 18,837,209 18,793,553 Incremental shares assumed for stock options and RSUs 142,950 201,537 148,110 204,927 Weighted-average number of dilutive shares outstanding 18,932,511 19,007,297 18,985,319 18,998,480 Basic earnings per common share $ 0.55 $ 0.58 $ 1.12 $ 1.14 Diluted earnings per common share $ 0.55 $ 0.58 $ 1.11 $ 1.13 Comprehensive income — U.S. GAAP generally requires that recognized revenues, expenses, gains and losses be included in net income. Although certain changes in assets and liabilities, such as unrealized gains and losses on available for sale securities, net of the related income tax effect, are reported as a separate component of the equity section of the consolidated balance sheets, such items, along with net income, are components of comprehensive income. Impact of recent authoritative accounting guidance — The Accounting Standards Codification™ (“ASC”) is the Financial Accounting Standards Board’s (“FASB”) officially recognized source of authoritative GAAP applicable to all public and non-public non-governmental entities. Periodically, the FASB will issue Accounting Standard Updates (“ASU”) to its ASC. Rules and interpretive releases of the SEC under the authority of the federal securities laws are also sources of authoritative GAAP for us as an SEC registrant. All other accounting literature is non-authoritative. In December 2019, FASB issued ASU 2019-12, Income Taxes. The amendments in this ASU simplify the accounting for income taxes by removing certain exceptions to the general principles in Topic 740. The amendments also improve consistent application of and simplify GAAP for other areas of Topic 740 by clarifying and amending existing guidance. For public business entities, the amendments in this ASU are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020. For all other entities, the amendments are effective for fiscal years beginning after December 15, 2021, and interim periods within fiscal years beginning after December 15, 2022. Early adoption of the amendments is permitted, including adoption in any interim period for (1) public business entities for periods for which financial statements have not yet been issued and (2) all other entities for periods for which financial statements have not yet been made available for issuance. An entity that elects to early adopt the amendments in an interim period should reflect any adjustments as of the beginning of the annual period that includes that interim period. Additionally, an entity that elects early adoption must adopt all the amendments in the same period. Adoption of ASU 2019-12 is not expected to have a material impact on the Company’s Consolidated Financial Statements. Note 1 — Basis of Presentation and Significant Accounting Policies – Continued In August 2018, FASB issued ASU 2018-15, Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract. The amendments in this ASU broaden the scope of ASC Subtopic 350-40 to include costs incurred to implement a hosting arrangement that is a service contract. The amendments align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). The costs are capitalized or expensed depending on the nature of the costs and the project stage duri

Performance-based grading follows the Company’s definitions of Pass, Special Mention, Substandard and Doubtful, which are consistent with published definitions of regulatory risk classifications. Definitions of Pass, Special Mention, Substandard, and Doubtful are summarized as follows: Pass : A Pass asset is higher quality and does not fit any of the other categories described below. The likelihood of loss is considered remote. Special Mention : A Special Mention asset has potential weaknesses that may be temporary or, if left uncorrected, may result in a loss. While concerns exist, the Company is currently protected and loss is considered unlikely and not imminent. Substandard : A Substandard asset is inadequately protected by the current sound net worth and paying capacity of the obligor or of the collateral pledged, if any. Assets so classified have well defined weaknesses and are characterized by the distinct possibility that the Company may sustain some loss if deficiencies are not corrected. Doubtful : A Doubtful asset has all the weaknesses inherent in a Substandard asset with the added characteristics that the weaknesses make collection or liquidation in full highly questionable. Note 3 — Loans and Allowance for Credit Losses – Continued For consumer loans, the Company generally assigns internal risk grades similar to those described above based on payment performance.

Prior to adoption of ASC 326, purchased loans, including loans acquired in business combinations, were recorded at their fair value at the acquisition date. Credit discounts were included in the determination of fair value; therefore, an allowance for loan and lease losses was not recorded at the acquisition date. Acquired loans were evaluated upon acquisition and classified as either PCI or purchased non-credit-impaired. PCI loans reflect credit deterioration since origination such that it is probable at acquisition that the Company will be unable to collect all contractually required payments. The outstanding contractual unpaid principal balance of PCI loans, excluding acquisition accounting adjustments, was $6.2 million at December 31, 2019. As of December 31, 2019, the non-accretable difference between the contractually required payments and cash flows expected to be collected were $2.8 million. The carrying balance of PCI loans was $3.5 million at December 31, 2019. On January 1, 2020, the Company adopted ASC 326 using the modified retrospective method for all financial assets measured at amortized cost and off-balance sheet credit exposures. Results for reporting periods beginning after January 1, 2020 are presented under ASC 326 while prior period amounts continue to be reported in accordance with previously applicable GAAP. The Company adopted ASC 326 using the prospective transition approach for financial assets purchased through an acquisition or business combination. Loans that were previously classified as PCI and accounted for under ASC 310-30 were reclassified as PCD loans. In accordance with the new standard, management did not reassess whether PCI loans met the criteria of PCD loan as of the date of adoption. On January 1, 2020, the amortized cost basis for PCD loans was increased by $1.5 million to reflect the addition of ACL. The remaining noncredit discount will continue to be accreted into interest income over the remaining life of the portfolio. The outstanding contractual unpaid principal balance of PCD loans was $2.5 million at June 30, 2020. The following table presents the changes in the accretable yield for non-PCD loans for the six months ended June 30, 2020, and 2019: Six Months Ended June 30, (Dollars in thousands) 2020 2019 Balance, beginning of period $ 4,247 $ 5,884 Accretion to interest income (1,192 ) (874 ) Reclassification from non-accretable difference 402 96 Balance, end of period $ 3,457 $ 5,106 Note 3 — Loans and Allowance for Credit Losses – Continued Loans and Deposits to affiliates — The Company has entered into loan transactions with certain directors, affiliated companies and executive officers (“affiliates”). Such transactions were made in the ordinary course of business on substantially the same terms and conditions, including interest rates and collateral, as those prevailing at the same time for comparable transactions with other customers, and did not, in the opinion of management, involve more than normal credit risk or present other unfavorable features. Total outstanding loans with affiliates were approximately $7.9 million and $5.4 million as of June 30, 2020, and December 31, 2019, respectively. Available lines of credit for loans and credit cards to affiliates were approximately $3.9 million and $278,000 as of June 30, 2020, and December 31, 2019, respectively. Deposits from affiliates were $8.0 million and $4.5 million as of June 30, 2020 and December 31, 2019, respectively.

Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies	Note 4 — Commitments and Contingencies Litigation contingencies — The Company is involved in various claims, legal actions and complaints which arise in the ordinary course of business. In the Company’s opinion, all such matters are adequately covered by insurance, are without merit or are of such kind, or involve such amounts, that unfavorable disposition would not have a material adverse effect on the financial condition or results of operations of the Company. Commitments to extend credit — In the normal course of business, the Company has outstanding commitments and contingent liabilities, such as commitments to extend credit and unused credit card lines, which are not included in the accompanying consolidated financial statements. The Company’s exposure to credit loss in the event of non-performance by other parties to the financial instruments for commitments to extend credit and unused credit card lines is represented by the contractual or notional amount of those instruments. The Company uses the same credit policies in making such commitments as it does for instruments that are included in the consolidated balance sheets. Contractual amounts of off-balance sheet financial instruments were as follows: June 30, December 31, (Dollars in thousands) 2020 2019 Commitments to extend credit, including unsecured commitments of $12,822 and $32,995 as of June 30, 2020 and December 31, 2019, respectively $ 659,794 $ 632,577 Stand-by letters of credit and bond commitments, including unsecured commitments of $403 and $555 as of June 30, 2020 and December 31, 2019, respectively 23,493 23,860 Unused credit card lines, all unsecured 26,860 26,121 Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. The commitments to extend credit may expire without being drawn upon. Therefore, the total commitment amounts do not necessarily represent future cash requirements. The amount of collateral obtained, if it is deemed necessary by the Company, is based on management’s credit evaluation of the customer. Unused credit card lines are commitments for possible future extensions of credit to existing customers. These lines of credit are uncollateralized and usually do not contain a specified maturity date and may not be drawn upon to the total extent to which the Company is committed.

Fair Value

Fair Value Disclosures [Abstract]
Fair Value	Note 5 — Fair Value The Company measures and discloses certain assets and liabilities at fair value. The standard requires us to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. These two types of inputs create the following fair value hierarchy: • Level 1 – Quoted prices in active markets for identical instruments. • Level 2 – Observable inputs other than Level 1 including quoted prices in active markets for similar instruments, quoted prices in less active markets for identical or similar instruments, or other observable inputs that can be corroborated by observable market data. • Level 3 – Unobservable inputs supported by little or no market activity for financial instruments whose value is determined using pricing models, discounted cash flow methodologies, or similar techniques, as well as instruments for which the determination of fair value requires significant management judgment or estimation. The estimated fair value amounts of financial instruments have been determined by the Company using available market information and appropriate valuation methodologies. However, considerable judgment is required to interpret data to develop the estimates of fair value. Accordingly, the estimates presented herein are not necessarily indicative of the amounts the Company could realize at a future date. The use of different market assumptions and/or estimation methodologies may have a material effect on the estimated fair value amounts. In addition, reasonable comparability between financial institutions may not be likely due to the wide range of permitted valuation techniques and numerous estimates that must be made given the absence of active secondary markets for many of the financial instruments. This lack of uniform valuation methodologies also introduces a greater degree of subjectivity to these estimated fair values. The following methods were used to estimate the fair value of each class of financial instruments: Securities : The estimated fair values of investment securities are priced using current active market quotes, if available, which are considered Level 1 measurements. For most of the portfolio, matrix pricing based on the securities’ relationship to other benchmark quoted prices is used to establish the fair value. These measurements are considered Level 2. Level 3 measurements were determined using discounted cash flow analyses based on the net present value of each security’s projected cash flows using observable market data for similar securities. Non-marketable securities : The fair value is based upon the redemption value of the stock, which equates to its carrying value. Loans held for sale : The carrying value of these items is a reasonable estimate of their fair value. Loans held for investment : The fair value is estimated by discounting the future cash flows and estimated prepayments using the current rates at which similar loans would be made to borrowers with similar credit ratings and for the same remaining term. Some loan types’ fair value approximated carrying value because of their floating rate or expected maturity characteristics. Deposits : The carrying amount of deposits with no stated maturity, such as savings and checking accounts, is a reasonable estimate of their fair value. The market value of certificates of deposit is based upon the discounted value of contractual cash flows. The discount rate is determined using the rates currently offered on comparable instruments.

Regulatory Capital Requirements [Abstract]
Regulatory Capital Matters	Note 7 — Regulatory Capital Matters The Company is subject to various regulatory capital requirements administered by its primary federal regulator, the FDIC. Failure to meet the minimum regulatory capital requirements can initiate certain mandatory and possible additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company and its consolidated financial statements. Under the regulatory capital adequacy guidelines and regulatory framework for prompt corrective action, the Company must meet specific capital guidelines involving quantitative measures of the Company’s assets, liabilities, and certain off-balance-sheet items as calculated under regulatory accounting practices. The Company’s capital amounts and classification under the prompt corrective action guidelines are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors. As of June 30, 2020, the Company was categorized as well capitalized under the regulatory framework. To be categorized as well capitalized, an institution must maintain minimum common Tier 1 (“CET1”), Tier 1 risk-based capital, total risk-based capital, and Tier 1 to average assets (“Tier 1 Leverage”) capital ratios as disclosed in the table below. Note 7 — Regulatory Capital Matters – continued The Company’s actual and required capital amounts and ratios are as follows: June 30, 2020 Minimum Capital Well Capitalized Actual Requirement Requirement (Dollars in thousands) Amount Ratio Amount Ratio Amount Ratio Consolidated CET1 Capital to Risk-Weighted Assets $ 310,678 17.94 % $ 77,941 4.50 % $ 112,581 6.50 % Tier 1 Capital to Risk-Weighted Assets 310,678 17.94 % 103,921 6.00 % 138,561 8.00 % Total Risk-Based Capital to Risk-Weighted Assets 332,608 19.20 % 138,561 8.00 % 173,202 10.00 % Tier 1 Leverage 310,678 11.68 % 106,380 4.00 % NA NA Altabank TM CET1 Capital to Risk-Weighted Assets $ 305,829 17.66 % $ 77,922 4.50 % $ 112,554 6.50 % Tier 1 Capital to Risk-Weighted Assets 305,829 17.66 % 103,896 6.00 % 138,528 8.00 % Total Risk-Based Capital to Risk-Weighted Assets 327,759 18.93 % 138,528 8.00 % 173,160 10.00 % Tier 1 Leverage 305,829 11.52 % 106,207 4.00 % 132,759 5.00 % December 31, 2019 Minimum Capital Well Capitalized Actual Requirement Requirement (Dollars in thousands) Amount Ratio Amount Ratio Amount Ratio Consolidated CET1 Capital to Risk-Weighted Assets $ 302,291 17.18 % $ 79,193 4.50 % $ 114,390 6.50 % Tier 1 Capital to Risk-Weighted Assets 302,291 17.18 % 105,590 6.00 % 140,787 8.00 % Total Risk-Based Capital to Risk-Weighted Assets 324,415 18.43 % 140,787 8.00 % 175,984 10.00 % Tier 1 Leverage 302,291 12.67 % 95,431 4.00 % NA NA Altabank TM CET1 Capital to Risk-Weighted Assets $ 297,108 16.88 % $ 79,191 4.50 % $ 114,387 6.50 % Tier 1 Capital to Risk-Weighted Assets 297,108 16.88 % 105,588 6.00 % 140,784 8.00 % Total Risk-Based Capital to Risk-Weighted Assets 319,233 18.14 % 140,784 8.00 % 175,981 10.00 % Tier 1 Leverage 297,108 12.45 % 95,429 4.00 % 119,286 5.00 % Federal Reserve Board Regulations require maintenance of certain minimum reserve balances based on certain average deposits. On March 15, 2020, the Board of Governors of the Federal Reserve reduced reserve requirement ratios to zero percent effective March 26, 2020. This action eliminated reserve requirements for all depository institutions. The Bank had a reserve requirement of $9.4 million as of December 31, 2019. The Company’s Board of Directors may declare a cash or stock dividend out of retained earnings provided the regulatory minimum capital ratios are met. The Company plans to maintain capital ratios that meet the well-capitalized standards per the regulations and, therefore, dividend amounts may be correspondingly limited.

Disclosure Of Compensation Related Costs Sharebased Payments [Abstract]
Incentive Share-Based Plan and Other Employee Benefits	Note 8 — Incentive Share-Based Plan and Other Employee Benefits In May 2020, on approval by and at the recommendation of the Board of Directors (“Board”), the shareholders of the Company approved a share-based incentive plan (“the Plan”). The Plan provides for various share-based incentive awards including incentive share-based options, non-qualified share-based options, restricted shares, and stock appreciation rights to be granted to officers, directors and other key employees. The maximum aggregate number of shares that may be issued under the Plan is 1,000,000 common shares. The share-based awards are granted to participants under the Plan at a price not less than the fair value on the date of grant and for terms of up to ten years. The Plan also allows for granting of share-based awards to directors and consultants who are not employees of the Company. During the six months ended June 30, 2020, the Company granted 55,187 restricted stock units (“RSU”) at a weighted-average fair value of $29.02 per unit. All awards granted thru June 30, 2020 were done so under the prior employee incentive plan. Beginning July 1, 2020, any new grants awarded to associates will be under the new Plan. The RSUs generally vest over periods from one to three years. The Company recorded share-based compensation expense of $765,000 and $381,000 for the six months ended June 30, 2020 and 2019, respectively. Additionally, the Company did not grant any options for the purchase of common shares during the six months ended June 30, 2020, and 2019, respectively.

Basis of Presentation and Significant Accounting Policies (Policies)	6 Months Ended
	Jun. 30, 2020
Accounting Policies [Abstract]
Nature of Operations and Basis of Consolidation	Nature of operations and basis of consolidation — Altabancorp TM (“ALTA” or the “Company”) is a Utah corporation headquartered in American Fork, Utah. The Company operates all business activities through its wholly-owned banking subsidiary, Altabank TM (the “Bank”), which was organized in 1913. Altabank TM is a Utah state-chartered bank. Altabank TM operates under the jurisdiction of the Utah Department of Financial Institutions (“UDFI”), and its deposits are insured by the Federal Deposit Insurance Corporation (“FDIC”). Altabank TM is not a member of the Federal Reserve System; however, ALTA is operated as a bank holding company under the Federal Bank Holding Company Act of 1956 and is the sole shareholder of Altabank TM . Both ALTA and Altabank TM are subject to periodic examination by all of the applicable federal and state regulatory agencies and file periodic reports and other information with such agencies. The Company considers Altabank TM to be its sole operating segment. Altabank TM TM TM TM TM The accompanying unaudited interim consolidated financial statements include the accounts of the Company together with its subsidiary Bank. All intercompany transactions and balances have been eliminated. These unaudited interim consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (GAAP) for interim financial information and in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X as promulgated by the Securities and Exchange Commission (SEC). In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation of the financial position and results of operations for the periods presented have been included. Certain information and disclosures normally included in annual financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to the rules and regulations of the SEC and the accounting standards for interim financial statements.
Use of Estimates	Use of estimates — The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires management to make estimates and assumptions. These estimates and assumptions affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reported period. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for credit losses (“ACL”), the determination of the fair value of certain financial instruments, the valuation of real estate acquired through foreclosure, deferred income tax assets, and share-based compensation.
Reclassifications	Reclassifications — Certain reclassifications have been made to the 2019 Consolidated Financial Statements and/or schedules to conform to the 2020 presentation. These reclassifications may have affected certain ratios for the prior periods. The effect of these reclassifications is considered immaterial.
Business Combinations	Business combinations — Business combinations are accounted for using the acquisition method of accounting and, accordingly, assets acquired and liabilities assumed, both tangible and intangible, and consideration exchanged are recorded at fair value on the acquisition date. The excess purchase consideration over fair value of net assets acquired is recorded as goodwill. Expenses incurred in connection with a business combination are expensed as incurred. Changes in deferred tax asset valuation allowances related to acquired tax uncertainties are recognized in net income after the measurement period.
Cash and Cash Equivalents	Cash and cash equivalents — Cash and cash equivalents consist of cash on hand, amounts due from banks, interest bearing deposits, and federal funds sold, all of which have original maturities of three months or less. The Company places its cash with high credit quality institutions. The amounts on deposit fluctuate and, at times, exceed the insured limit by the FDIC, which potentially subjects the Company to credit risk.
Investment Securities	Investment securities — Investment securities are classified as held to maturity (“HTM”) when the Company has the positive intent and ability to hold the securities to maturity. Investment securities are classified as available for sale (“AFS”) when the Company has the intent of holding the security for an indefinite period of time, but not necessarily to maturity. The Company determines the appropriate classification at the time of purchase, and periodically thereafter. Investment securities classified as HTM are carried at amortized cost. Investment securities classified as AFS are reported at fair value. As the fair value of AFS securities changes, the changes are reported (net of tax, if applicable) in comprehensive income and as an element of accumulated other comprehensive income/loss (“AOCI”) in shareholder’s equity. Interest income includes amortization of purchase premium or discount. Premiums and discounts on securities are generally amortized on the level-yield method without anticipating prepayments, except for callable debt securities. Premiums on callable debt securities are amortized to the earliest call date. When AFS securities, specifically identified, are sold, the unrealized gain or loss is reclassified from AOCI to non-interest income. A debt security is placed on nonaccrual status at the time any principal or interest payments become greater than 90 days delinquent. Delinquent interest accrued but not received for a security placed on nonaccrual is reversed against interest income. The Company did not have any accrued interest reversed against interest income for the six months ended June 30, 2020.
Allowance For Credit Losses - AFS Securities	Allowance for credit losses – AFS securities —For AFS debt securities in an unrealized loss position, management assesses whether the Company intends to sell or it is more likely than not that the Company will be required to sell the security before recovery of its amortized cost basis. If either criterion regarding intent or requirement to sell is met, the security’s amortized cost basis is written down to the fair value through non-interest income. For AFS debt securities that do not meet the aforementioned criteria, management evaluates whether the decline in fair value has resulted from credit losses or other factors. In making this assessment, management considers the extent to which the fair value is less than amortized cost, any changes to the rating of the security by a rating agency, and any adverse conditions specifically related to the security, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security is compared to the amortized cost basis of the security. If the present value of cash flows expected to be collected is less than the amortized cost basis, a credit loss exists and an allowance for credit losses is recorded for the credit loss, which is limited by the amount that the fair value is less than the amortized cost basis. Any impairment that has not been recorded through an allowance for credit losses is recognized in AOCI. Changes in the allowance for credit losses are recorded as a Provision for Credit Losses (“PCL”). Losses are charged against the allowance when management believes the uncollectibility of an AFS security is confirmed or when either of the criterion regarding intent or requirement to sell is met.
Non-Marketable Equity Securities	Non-marketable equity securities — Non-marketable equity securities primarily consist of Federal Home Loan Bank (“FHLB”) stock. FHLB stock is restricted because such stock may only be sold to FHLB at its par value. Due to the restrictive terms, and the lack of a readily determinable market value, FHLB stock is carried at cost. The investments in FHLB stock are required investments related to the Bank’s borrowings from FHLB. FHLB obtains its funding primarily through issuance of consolidated obligations of the FHLB system. The U.S. government does not guarantee these obligations, and each of the regional FHLBs is jointly and severally liable for repayment of each other’s debt.
Loans Held for Sale	Loans held for sale —Single-family residential mortgage loans originated with the intent to be sold in the secondary market are considered held for sale. Loans with best effort delivery commitments are carried at the lower of aggregate cost or estimated fair value. Loans under mandatory delivery commitments are carried at fair value in order to match changes in the value of the loans with the value of the economic hedges on the loans. Fair values for loans held for sale are determined by comparing actual loan rates to current secondary market prices for similar loans. Net unrealized losses on loans held for sale that are carried at lower of cost or market are recognized through the valuation allowance by charges to income. Mortgage loans held for sale are generally sold with the mortgage servicing rights. 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. Substantially all of the residential mortgage loans originated are sold to larger financial institutions.
Loans Held for Investment	Loans held for investment — Loans that management has the intent and ability to hold for the foreseeable future or until maturity or pay-off are reported at amortized cost, net of the allowance for credit losses. Amortized cost includes the principal balance outstanding, net of purchase premiums and discounts, deferred loan fees and costs. Accrued interest is reported as a separate line item on the unaudited consolidated balance sheets. Interest income is accrued on the unpaid principal balance. Loan origination fees, net of certain direct origination costs, are deferred and recognized in interest income using the effective interest method without anticipating prepayments. Interest income on mortgage and commercial loans is discontinued and placed on nonaccrual status at the time the loan is 90 days delinquent, unless the loan is well secured and in process of collection. Mortgage loans are charged off at 180 days past due, and commercial loan are charged-off to the extent principal or interest is deemed uncollectible. Consumer and credit card loans continue to accrue interest until they are charged-off no later than 120 days past due unless the loan is in the process of collection. Past-due status is based on the contractual terms of the loan. In all cases, loans are placed on nonaccrual or charge-off at an earlier date if collection of principal or interest is considered doubtful. All interest accrued but not received for loans placed on nonaccrual is reversed against interest income. Interest received on such loans is accounted for on the cash-basis or cost-recovery method, until qualifying for return to accrual. Under the cost-recovery method, interest income is not recognized until the loan balance is reduced to zero. Under the cash-basis method, interest income is recorded when the payment is received in cash. Loans are returned to accrual status when all principal and interest amounts contractually due are brought current and future payments are reasonably assured.
Troubled Debt Restructurings ("TDR")	Troubled debt restructurings (“TDR”) —A loan for which the terms have been modified resulting in a concession, and for which the borrower is experiencing financial difficulties, is considered to be a TDR. TDRs are then evaluated to determine if the TDR loan has estimated credit losses using the same methodology used for other individually evaluated loans as described in the next section. With the recent COVID-19 pandemic, the number of loans that have had loan payments deferred has significantly increased. In accordance with regulatory guidance, to the extent that the borrower was not experiencing financial difficulties prior to the pandemic, such modifications have not been classified as TDRs.
Individually Evaluated Loans	Individually evaluated loans — The Company considers loans individually evaluated when, based on current information and events, 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. Such loans are generally classified as Substandard or Doubtful loans (see Note 3). Individually evaluated loans are measured based on the present value of expected future cash flows discounted at the loan’s effective interest rate, the loan’s observable market price, or the fair value of the collateral, adjusted for selling costs, if the loan is collateral dependent. Changes in these values are recorded to the ACL through the PCL. Factors considered by management in determining estimated credit losses include payment status, collateral value and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as individually evaluated. Management determines the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower’s prior payment record and the amount of the shortfall in relation to the principal and interest owed.
Acquired Loans	Acquired loans – Loans acquired through purchase or through a business combination are recorded at their fair value at the acquisition date, including estimates of current expected credit losses. Some acquired loans have experienced more than insignificant credit deterioration since origination. Such loans are defined as Purchased Credit Deteriorated (“PCD”). The Company makes the determination if a loan is PCD by considering past due and/or nonaccrual status, prior designation of a troubled debt restructuring, or other factors that may suggest the Company will not be able to collect all contractual payments due. Subsequent to acquisition, the amount of expected credit losses as of the acquisition date is added to the purchase price of PCD loans with an offsetting entry to ACL. Any difference between the unpaid principal balance and the amortized cost basis of the PCD loan as of the acquisition date is the non-credit discount or premium. The non-credit discount recorded at acquisition is amortized or accreted into interest income over the remaining life of the PCD loan on an effective interest method. To the extent that management changes the Company’s estimate of expected credit losses on PCD loans, the ACL will be increased or decreased with a corresponding entry to PCL. Some acquired loans may not have experienced more than insignificant credit deterioration since origination. Such loans are defined as Purchased non-Credit Deteriorated (“Non-PCD”) loans. Non-PCD loans are also recorded at fair value at the time of acquisition, including estimates of current expected credit losses. However, any current expected credit losses estimated as of the acquisition date are not added to the purchase price with an offsetting entry to ACL, but rather such estimate is included in the difference between the unpaid principal balance and the amortized cost basis of the Non-PCD loan. This credit and non-credit discount is amortized or accreted into interest income over the remaining life of the Non-PCD loan on an effective interest method. In addition, an allowance for credit losses is determined for Non-PCD loans using the same methodology as loans held for investment with an offset recorded to PCL. An acquired loan previously classified by the seller as a TDR is no longer classified as such at the date of acquisition. Past due status is reported based on contractual payment status. Changes to the ACL for acquired loans are recorded through PCL after adoption.
Allowance for Credit Losses - Loans	Allowance for credit losses – Loans — Credit risk is inherent in the business of extending loans and leases to borrowers. Normally, this credit risk is addressed through a valuation allowance termed allowance for credit losses. The ACL represents management’s estimate of current expected credit losses (“CECL”) inherent in the loan portfolio at each balance sheet date. Netted against the outstanding loan balance, this ACL reduces the balance to the Company’s estimate of what will be collected from borrowers. The ACL is established through charges to current period earnings by recording a PCL. When losses become specifically identifiable and quantifiable, the loan balance is reduced through recording a charge-off against the ACL. Should payments be received on a charged-off loan, the payment is credited to the ACL as a recovery. Management estimates the ACL using relevant available information, from internal and external sources, relating to past events, current conditions, and reasonable and supportable forecasts. Historical credit loss experience, either internal or peer information, provides the basis for the estimation of expected credit losses. Adjustments to historical loss information are made, using qualitative factors, when management expects current conditions and reasonable and supportable forecasts to differ from the conditions that existed for the period over which historical information was evaluated. Management must exercise significant judgment when evaluating the effect of qualitative factors on the amount of the ACL because data may not be reasonably available or directly applicable for management to determine the precise impact of a factor on the collectability of the loan portfolio as of the evaluation date. Management considers qualitative or environmental factors that are likely to cause estimated credit losses associated with our existing portfolio to differ from historical loss experience, including but not limited to: i) changes in lending policies and procedures; ii) changes in underwriting standards and collection, charge-off, and recovery practices not considered elsewhere in estimating credit losses; iii) changes in international, national, regional, and local economic and business conditions and developments that affect the collectability of the portfolio, including the condition of various market segments; iv) changes in the nature and volume of the portfolio and in the terms of loans; v) changes in the experience, ability, and depth of lending management and other relevant staff; vi) changes in the volume and severity of past due loans, the volume of nonaccrual loans, and the volume and severity of adversely classified or graded loans; vii) changes in the quality of the institution’s loan review system; viii) changes in the value of underlying collateral for collateral-dependent loans; ix) the existence and effect of any concentrations of credit, and changes in the level of such concentrations; and, x) the effect of other external factors such as competition and legal and regulatory requirements on the level of estimated credit losses in the institution’s existing portfolio. This evaluation is inherently subjective, as it requires estimates that are susceptible to significant revision, as more information becomes available. Note 1 — Basis of Presentation and Significant Accounting Policies – Continued The Company used the weighted average remaining maturity (or “WARM”) approach, adjusted for prepayments, to calculate CECL at June 30, 2020 and segmented its loan portfolio into seventeen loan segments based on similar risk characteristics. Management may change the approach used to calculated current expected credit losses or loan segments from time-to-time as the Company improves credit loss estimation techniques. The Company has elected to exclude accrued interest receivable from its calculation of the ACL.
Off-Balance-Sheet Credit Related Financial Instruments	Off-balance sheet credit related financial instruments — In the ordinary course of business, the Company has entered into commitments to extend credit, including commitments under credit card arrangements, commercial letters of credit, and standby letters of credit. Such financial instruments are recorded when they are funded.
Allowance For Credit Losses On Off-Balance Sheet Credit Exposures	Allowance for credit losses on off-balance sheet credit exposures — The Company estimates expected credit losses on off-balance sheet credit exposures using the same CECL historical loss rates applied to loans held for investment over the contractual period in which the Company is exposed to credit risk through a contractual obligation to extend credit, unless that obligation is unconditionally cancellable by the Company, adjusted for funding factors. The allowance for credit losses on off-balance sheet credit exposures is reported in other liabilities on the unaudited consolidated balance sheets with an offset to other non-interest expense. The estimate of CECL includes consideration of the likelihood that funding will occur and an estimate of expected credit losses on commitments expected to be funded over their estimated life.
Premises and Equipment	Premises and equipment — Land is carried at cost. Premises and equipment are carried at cost, net of accumulated depreciation and amortization. Depreciation and amortization expense is computed using the straight-line method based on the estimated useful lives of the related assets below: Building and building improvements 15 to 40 years Leasehold improvements 3 to 15 years Furniture and equipment 3 to 15 years Computers, software and equipment 3 to 5 years Maintenance and repairs are expensed as incurred while major additions and improvements are capitalized.
Bank-Owned Life Insurance	Bank-owned life insurance (“BOLI”) — The Bank has purchased life insurance policies. These policies provide protection against the adverse financial effects that could result from the death of a key employee and provide tax-exempt income to offset expenses associated with the plans. It is the Bank’s intent to hold these policies as a long-term investment; however, there may be an income tax impact if the Bank chooses to surrender certain policies. Although the lives of individual current or former management-level employees are insured, the Bank is the owner and sole or partial beneficiary. BOLI is carried at the cash surrender value (“CSV”) of the underlying insurance contract. Changes in the CSV and any death benefits received in excess of the CSV are recognized as non-interest income.
Goodwill	Goodwill — Goodwill represents the excess of the purchase considerations paid over the fair value of the assets acquired, net of the fair values of liabilities assumed in a business combination and is not amortized but is reviewed annually, or more frequently as current circumstances and conditions warrant, for impairment. An assessment of qualitative factors is completed to determine if it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If the qualitative analysis concludes that further analysis is required, then a quantitative impairment test would be completed. The quantitative goodwill impairment compares the reporting unit's estimated fair values, including goodwill, to its carrying amount. If the carrying amount exceeds its reporting unit’s fair value, then an impairment loss would be recognized as a charge to earnings but is limited by the amount of goodwill allocated to that reporting unit.
Other Intangible Assets	Other intangible assets — Other intangible assets consist primarily of core deposit intangibles (“CDI”), which are amounts recorded in business combinations or deposit purchase transactions related to the value of transaction-related deposits and the value of the client relationships associated with the deposits. Core deposit intangibles are amortized over the estimated useful life of such deposits. These assets are reviewed at least annually for events or circumstances that could affect their recoverability. These events could include loss of the underlying core deposits, increased competition or adverse changes in the economy. To the extent other identifiable intangible assets are deemed unrecoverable; impairment losses are recorded in other non-interest expense to reduce the carrying amount of the assets.
Mortgage and Other Servicing Rights	Mortgage and other servicing rights — Mortgage and other servicing rights are recognized as separate assets when rights are acquired through purchase of such rights or through the sale of loans. Generally, purchased servicing rights are capitalized at the cost to acquire the rights. For loans sold, the fair value of the servicing rights are estimated and capitalized. Fair value is based on market prices for comparable servicing rights contracts. Capitalized servicing rights are reported in other assets and are amortized into non-interest income in proportion to, and over the period of, the estimated future net servicing income of the underlying financial assets.
Other Real Estate Owned	Other real estate owned — Assets acquired through, or in lieu of, loan foreclosure are held for sale and are initially recorded at the lower of the carrying amount of the foreclosed loan or the fair value of the foreclosed asset, less costs to sell, at the date of foreclosure. Subsequent to foreclosure, management periodically performs valuations and the assets are carried at the lower of carrying amount or fair value, less selling costs. Revenues and expenses from operations and changes in the valuation allowance are included in other real estate owned expense.
Transfers of Financial Assets	Transfers of financial assets — Transfers of financial assets are accounted for as sales when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when (1) the assets have been isolated from the Company, (2) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and (3) the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity.
Income Taxes	Income taxes — Deferred income tax assets and deferred income tax liabilities represent the tax effect of temporary differences between financial reporting and tax reporting measured at enacted tax rates in effect for the year in which the differences are expected to reverse. The Company recognizes only the impact of tax positions that, based on their technical merits, are more likely than not to be sustained upon an audit by the taxing authority. Developing the provision for income taxes, including the effective tax rate and analysis of potential tax exposure items, if any, requires significant judgment and expertise in federal and state income tax laws, regulations and strategies, including the determination of deferred income tax assets and liabilities and any estimated valuation allowances deemed necessary to value deferred income tax assets. Judgments and tax strategies are subject to audit by various taxing authorities. While the Company believes it has no significant uncertain income tax positions in the consolidated financial statements, adverse determinations by these taxing authorities could have a material adverse effect on the consolidated financial positions, result of operations, or cash flows.
Share Based Compensation Plans	Share-based compensation plans — The fair value of incentive share-based awards is recorded as compensation expense over the vesting period of the award. Compensation expense for stock options is estimated at the date of grant using the Black-Scholes option-pricing model. Compensation expense for RSUs is based on the fair value of the Company’s common shares at the date of grant. RSU awards generally vest in thirds over three years from date of grant.
Earnings Per Share	Earnings per share — Basic earnings per common share represents income available to common shareholders divided by the weighted-average number of common shares outstanding during the period. Diluted earnings per share reflect additional common shares that would have been outstanding if dilutive potential common shares had been issued. Potential common shares include shares that may be issued by the Company for outstanding stock options determined using the treasury stock method and for all outstanding RSUs. Note 1 — Basis of Presentation and Significant Accounting Policies – Continued Earnings per common share have been computed based on the following: Three Months Ended Six Months Ended June 30, June 30, (Dollars in thousands, except share and per share data) 2020 2019 2020 2019 Numerator Net income $ 10,338 $ 10,989 $ 21,111 $ 21,494 Denominator Weighted-average number of common shares outstanding 18,789,561 18,805,760 18,837,209 18,793,553 Incremental shares assumed for stock options and RSUs 142,950 201,537 148,110 204,927 Weighted-average number of dilutive shares outstanding 18,932,511 19,007,297 18,985,319 18,998,480 Basic earnings per common share $ 0.55 $ 0.58 $ 1.12 $ 1.14 Diluted earnings per common share $ 0.55 $ 0.58 $ 1.11 $ 1.13
Comprehensive Income	Comprehensive income — U.S. GAAP generally requires that recognized revenues, expenses, gains and losses be included in net income. Although certain changes in assets and liabilities, such as unrealized gains and losses on available for sale securities, net of the related income tax effect, are reported as a separate component of the equity section of the consolidated balance sheets, such items, along with net income, are components of comprehensive income.
Impact of Recent Authoritative Accounting Guidance	Impact of recent authoritative accounting guidance — The Accounting Standards Codification™ (“ASC”) is the Financial Accounting Standards Board’s (“FASB”) officially recognized source of authoritative GAAP applicable to all public and non-public non-governmental entities. Periodically, the FASB will issue Accounting Standard Updates (“ASU”) to its ASC. Rules and interpretive releases of the SEC under the authority of the federal securities laws are also sources of authoritative GAAP for us as an SEC registrant. All other accounting literature is non-authoritative. In December 2019, FASB issued ASU 2019-12, Income Taxes. The amendments in this ASU simplify the accounting for income taxes by removing certain exceptions to the general principles in Topic 740. The amendments also improve consistent application of and simplify GAAP for other areas of Topic 740 by clarifying and amending existing guidance. For public business entities, the amendments in this ASU are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020. For all other entities, the amendments are effective for fiscal years beginning after December 15, 2021, and interim periods within fiscal years beginning after December 15, 2022. Early adoption of the amendments is permitted, including adoption in any interim period for (1) public business entities for periods for which financial statements have not yet been issued and (2) all other entities for periods for which financial statements have not yet been made available for issuance. An entity that elects to early adopt the amendments in an interim period should reflect any adjustments as of the beginning of the annual period that includes that interim period. Additionally, an entity that elects early adoption must adopt all the amendments in the same period. Adoption of ASU 2019-12 is not expected to have a material impact on the Company’s Consolidated Financial Statements. Note 1 — Basis of Presentation and Significant Accounting Policies – Continued In August 2018, FASB issued ASU 2018-15, Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract. The amendments in this ASU broaden the scope of ASC Subtopic 350-40 to include costs incurred to implement a hosting arrangement that is a service contract. The amendments align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). The costs are capitalized or expensed depending on the nature of the costs and the project stage during which they are incurred, consistent with the accounting for costs for internal-use software. The amendments in this ASU result in consistent capitalization of implementation costs of a hosting arrangement that is a service contract and implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). The accounting for the service element of a hosting arrangement that is a service contract is not affected by the amendments in this ASU. The amendments in this ASU were applied prospectively to all implementation costs incurred after the date of adoption. Adoption of ASU 2018-15 did not have a material impact on the Company’s Consolidated Financial Statements. In August 2018, FASB issued ASU 2018-13, Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement. The amendments in this ASU modify the disclosure requirements on fair value measurements in Topic 820, Fair Value Measurement. The ASU removes, modifies and adds disclosure requirements in Topic 820. The following disclosure requirements were removed: 1) the amount and reasons for transfers between Level 1 and Level 2 of the fair value hierarchy, 2) the policy for timing of transfers between levels, and 3) the valuation processes for Level 3 fair value measurements. This ASU modified disclosure requirements by requiring that the measurement uncertainty disclosure communicates information about the uncertainty in measurement as of the reporting date. The following disclosure requirements were added: 1) changes in unrealized gains and losses for the period included in other comprehensive income for the recurring Level 3 fair value measurements held at the end of the reporting period, and 2) the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. The amendments in this ASU are effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Adoption of ASU 2018-13 did not have a material impact on the Company’s Consolidated Financial Statements. In June 2016, the Financial Accounting Standard Board (“FASB”) issued Accounting Standard Update (“ASU”) No. 2016-13, “Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.” The ASU significantly changes the accounting for credit loss measurement on loans and debt securities. For loans and held-to-maturity debt securities, the ASU requires a current expected credit loss measurement to estimate the allowance for credit losses for the remaining estimated life of the financial asset (including off-balance sheet credit exposures) using historical experience, current conditions, and reasonable and supportable forecasts. The ASU eliminates the existing guidance for purchased credit impaired (“PCI”) loans but requires an allowance for purchased financial assets with more than an insignificant deterioration since origination, otherwise known as purchased credit deteriorated assets. In addition, the ASU modifies the other-than-temporary impairment model for available-for-sale debt securities to require an allowance for credit impairment instead of a direct write-down, which allows for reversal of credit impairments in future periods based on an improvement in credit. This ASU was effective for interim and annual reporting periods beginning after December 15, 2019. On October 16, 2019, the FASB voted to delay the adoption of CECL by two years to January 2023 for private companies, not-for-profit companies, and certain small public companies that meet the definition of a smaller reporting company (“SRC”), as defined by the Securities and Exchange Commission. To meet the requirements of an SRC, an entity must be an issuer as defined by the SEC and have public float of less than $250 million, or public float of less than $700 million and annual revenues of less than $100 million. As of June 30, 2019, our public float was $466 million and annual revenues for 2018 were $130 million. As a result, we are not an SRC and, therefore, were required to adopt the ASU effective January 1, 2020. Note 1 — Basis of Presentation and Significant Accounting Policies – Continued On January 1, 2020, the Company adopted ASC 326 using the modified retrospective method for all financial assets measured at amortized cost and off-balance sheet credit exposures. Results for reporting periods beginning after January 1, 2020, are presented under ASC 326 while prior period amounts continue to be reported in accordance with previously applicable GAAP. The Company adopted ASC 326 using the prospective transition approach for financial assets purchased through an acquisition or business combination. Loans that were previously classified as PCI and accounted for under ASC 310-30 were reclassified as PCD loans. In accordance with the new standard, management did not reassess whether PCI loans met the criteria of PCD loan as of the date of adoption. On January 1, 2020 the amortized cost basis for PCD loans was increased by $1.5 million to reflect the addition of credit discounts to ACL. The remaining noncredit discount will be accreted into interest income over the remaining life of the portfolio. For Non-PCD loans, the Company increased its ACL by $2.6 million using the same methodology used for loans held for investment. The remaining credit and noncredit discount will be accreted into interest income over the remaining life of the portfolio. The Company further increased its ACL by $5.4 million to reflect the change in accounting methodology for CECL. The following table illustrates the impact of the adoption of ASC 326: January 1, 2020 (Dollars in thousands) Reported Under ASC 326 Reported Pre Adoption Impact of ASC 326 Adoption Assets: Allowance for credit losses: Commercial real estate loans: Real estate term $ 12,683 $ 12,275 $ 408 Construction and land development 13,393 6,990 6,403 Total commercial real estate 26,076 19,265 6,811 Commercial and industrial 11,541 10,892 649 Consumer loans: Residential and home equity 2,635 1,118 1,517 Consumer and other 640 151 489 Total consumer 3,275 1,269 2,006 Total allowance for credit losses on loans $ 40,892 $ 31,426 $ 9,466 Liabilities and shareholders’ equity: Reserve for off-balance sheet obligations 1,669 880 789 Shareholders’ equity 325,682 332,362 (6,680 ) The Company expects greater volatility in its earnings and those of other banks after adoption due to the nature and time horizon used to calculate CECL. In addition, the Company expects a potential negative impact to credit availability and reduced loan terms to borrowers as this ASU is adopted by financial institutions. Lastly, the Company expects a lack of comparability with financial performance to many of its peers as it adopts this ASU, due to delayed adoption for public companies with total assets similar in size to us and the recent option to delay implementation.
