Accounting Policies [Abstract]
Basis of Presentation and Significant Accounting Policies	Nature of operations and basis of consolidation — People’s Utah Bancorp, Inc. (“PUB” or the “Company”) is a Utah corporation headquartered in American Fork, Utah. The Company operates all business activities through its wholly-owned banking subsidiary, People’s Intermountain Bank (“PIB” or the “Bank”), which was organized in 1913. The Bank is a Utah state chartered bank. The Bank operates under the jurisdiction of the Utah Department of Financial Institutions, and its deposits are insured by the Federal Deposit Insurance Corporation (“FDIC”). The Bank is not a member of the Federal Reserve System; however, PUB is operated as a bank holding company under the Federal Bank Holding Company Act of 1956 and is the sole shareholder of the Bank. Both PUB and the Bank are subject to periodic examination by applicable federal and state regulatory agencies and file periodic reports and other information with the agencies. The Company considers the Bank to be its sole operating segment. PIB is a community bank that provides highly personalized retail and commercial banking products and services to small and medium sized businesses and to individuals. Products and services are offered primarily through 26 retail branch locations throughout Utah and southern Idaho. PIB has three banking divisions, Bank of American Fork, Lewiston State Bank, and People’s Town & Country Bank; and a mortgage division, People’s Intermountain Bank Mortgage. The Bank offers a full range of short-term to long-term commercial, personal and mortgage loans. Commercial loans include secured and unsecured loans for working capital (including inventory and accounts receivable), business expansion (including acquisition of real estate and improvements), and purchase of equipment and machinery. Consumer loans include secured and unsecured loans to finance automobiles, home improvements, and personal investments. The Bank also offers mortgage loans secured by personal residences. The Bank offers a full range of deposit services typically available in most financial institutions, including checking accounts, savings accounts, and time deposits. The Bank solicits these accounts from individuals, businesses, associations and organizations, and governmental entities. 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 preparing these financial statements, the Company has evaluated events and transactions subsequent to September 30, 2019, for potential recognition or disclosure. 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. Certain reclassifications have been made to the 2018 Consolidated Financial Statements and/or schedules to conform to the 2019 presentation. These reclassifications may have affected certain ratios for the prior periods. The effect of these reclassifications is considered immaterial. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect amounts reported in the financial statements. Various elements of the Company’s accounting policies, by their nature, are inherently subject to estimation techniques, valuation assumptions and other subjective assessments. In particular, management has identified several accounting policies that, due to the judgments, estimates and assumptions inherent in those policies, are significant to an understanding of the Company’s financial statements. These policies relate to (i) the methodology for the recognition of interest income, (ii) determination of the provision and allowance for loan losses, (iii) the valuation of financial assets and liabilities recorded at fair value, including other-than-temporary impairment (OTTI) losses, (iv) the valuation of intangibles, such as goodwill, core deposit intangibles (CDI) and mortgage servicing rights, (v) the valuation of real estate held for sale, (vi) the valuation of assets and liabilities acquired in business combinations and subsequent recognition of related income and expense, and (vii) the valuation or recognition of deferred tax assets and liabilities. These policies and judgments, estimates and assumptions are described in greater detail in subsequent notes to the Consolidated Financial Statements and Management’s Discussion and Analysis of Financial Condition and Results of Operations (Critical Accounting Policies) in our Annual Report on Form 10-K for the year ended December 31, 2018 filed with the SEC (2018 Form 10-K). There have been no significant changes in our application of these accounting policies during the first nine months of 2019, except as described later in Note 1. The information included in this Form 10-Q should be read in conjunction with our 2018 Form 10-K. Interim results are not necessarily indicative of results for a full year or any other interim period. Note 1 — Basis of Presentation and Significant Accounting Policies – Continued 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 restricted stock units (“RSU”). Reclassifications — Certain amounts in the prior period’s financial statements have been reclassified to conform to the current period’s presentation. 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 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. This ASU is effective for fiscal years beginning after December 15, 2019 and interim periods within those fiscal years. The amendments in this ASU should be applied either retrospectively or prospectively to all implementation costs incurred after the date of adoption. Adoption of ASU 2018-15 is not expected to 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. This 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 the disclosure requirements to require 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. An entity is permitted to early adopt any removed or modified disclosures upon issuance of this ASU and delay adoption of the additional disclosures until their effective date. Adoption of ASU 2018-13 is not expected to have a material impact on the Company’s Consolidated Financial Statements. In June 2016, the FASB issued 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 (“CECL”) measurement to estimate the allowance for credit losses (“ACL”) 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 purchase credit deteriorated (“PCD”) 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 is 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 SEC. 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, the Company’s public float was $466 million and annual revenues for 2018 were $130 million. The Company is not an SRC and will be required to adopt the ASU effective January 1, 2020. Note 1 — Basis of Presentation and Significant Accounting Policies – Continued The implementation process includes evaluation of technical accounting topics; developing, validating and implementing models and methodologies used to calculate CECL; updating ACL documentation; validating internal controls; and overall operational readiness for adoption of the ASU. The Company is currently running new models and processes in parallel with existing models and processes under current accounting guidance in advance of the January 1, 2020 effective date. These parallel runs will focus on technical functionality of the CECL calculation, operational execution of the end-to-end process, as well as disclosure requirements. The Company has established a project team and a steering committee to provide cross-functional governance over and make key decisions relating to the project plan and the parallel runs. The Company intends to recognize an ACL for available for sale debt securities. The ACL on available for sale debt securities will be subject to a limitation based on the fair value of the debt securities. Based on the credit quality of existing debt securities, the Company does not expect the ACL for debt securities to be material. The Company expects to use the weighted average remaining maturity (“WARM”) approach, adjusted for prepayments, to calculate CECL. As described in the FASB Staff Question and Answers, the Company intends to use a qualitative approach to adjust historical loss information for current conditions and for reasonable and supportable forecasts, and then immediately revert to historical credit losses. As noted in section ASU 320-20-30-9, “An entity shall not rely solely on past events to estimate expected credit losses. When an entity uses historical loss information, it shall consider the need to adjust historical information to reflect the extent to which 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. The adjustments to historical loss information may be qualitative in nature and should reflect changes related to relevant data (such as changes in unemployment rates, property values, commodity values, delinquency, or other factors that are associated with credit losses on the financial asset or in the group of financial assets).” The Company is currently in the process of evaluating the impact of CECL on its earnings, financial position, and regulatory capital amounts and ratios related to loans. The Company expects its ACL to increase upon adoption, because the ACL will be required to cover the full remaining expected life of the portfolio, rather than the incurred loss model under current U.S. GAAP. In addition, a portion of the increase will be due to PCI loans that will be reclassified as PCD loans with the credit related non-accretable discount increasing both ACL and loan balances, but not retained earnings. However, accretable discounts held on non-PCD loans are not allowed to be moved to ACL as part of the adoption of this ASU. The Company will be required to set aside additional ACL for non-PCD loans through retained earnings upon adoption. The Company will continue to hold accretable discounts that will be recorded to interest income over the remaining life of non-PCD loans as well as a similar amount in ACL. 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 effective 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 the Company. The ultimate effect of CECL on the Company’s ACL will depend on the size and composition of the loan portfolio; the loan portfolio’s credit quality and economic conditions at the time of adoption; and any refinements to models, methodologies, and other key assumptions used. At adoption, the Company will have a cumulative effect adjustment to retained earnings for the change in the ACL, which the Company expects to negatively impact regulatory capital amounts and ratios. An increase in the Company’s ACL will result in a decrease in regulatory capital amounts and ratios. Bank regulatory agencies have provided regulatory capital relief for an initial capital decrease from the adoption of this ASU by allowing a phased adoption over three years, on a straight-line basis, which the Company expects to utilize. In February 2016, FASB issued ASU No. 2016-02, Leases (Topic 842). The amendments in this ASU require lessees to recognize the following for all leases (with the exception of short-term) at the commencement date: a lease liability, which is a lessee‘s obligation to make lease payments arising from a lease, measured on a discounted basis; and a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. The amendments in this ASU leave lessor accounting largely unchanged, although certain targeted improvements were made to align lessor accounting with the lessee accounting model. This ASU simplifies the accounting for sale and leaseback transactions primarily because lessees must recognize lease assets and lease liabilities. Note 1 — Basis of Presentation and Significant Accounting Policies – Continued Lessees will no longer be provided with a source of off-balance sheet financing. The Company adopted ASU No. 2016-02 effective January 1, 2019. The Company elected the transition option provided in ASU No. 2018-11 and applied the modified retrospective approach. The Company also elected certain relief options for practical expedients: the option to not separate lease and non-lease components and instead to account for them as a single lease component; and the option to not recognize right-of-use assets and lease liabilities that arise from short-term leases (i.e. leases with terms of twelve months or less). The Company has eight real property leases under non-cancelable operating leases, four of which are subject to this ASU that results in the recognition of right of use assets and lease liabilities. All of the Company’s equipment is owned or on short-term leases. The Company compiled a complete inventory of arrangements containing leases and analyzed the lease data necessary to meet the new requirements. The Company has recorded a $2.2 million right of use asset and a $2.2 million lease liability on its Consolidated Balance Sheets.

The primary focus of the amendment is to simplify hedge accounting and make the results of hedge transactions in the financial statements easier to understand. An ancillary result of the amendment is that an entity may make a one-time transfer of certain securities from the held to maturity classification to the available for sale classification. The amendment is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. As allowed under this accounting pronouncement, the Company elected to make a one-time transfer of $64.6 million of held to maturity securities to the available for sale classification as of January 1, 2019, and recorded an unrecognized loss of $19,000, net of taxes, to other comprehensive income. Note 2 — Investment Securities – continued At September 30, 2019 and December 31, 2018, the gross unrealized losses and the fair value for securities available for sale and held to maturity were as follows: September 30, 2019 Less Than 12 Months 12 Months or More Total Fair Unrealized Fair Unrealized Fair Unrealized (Dollars in thousands) Value Losses Value Losses Value Losses Available for Sale U.S. Government-sponsored securities $ - $ - $ 17,980 $ (20 ) $ 17,980 $ (20 ) Municipal securities 10,838 (25 ) 2,159 (18 ) 12,997 (43 ) Mortgage-backed securities 20,976 (59 ) 83,042 (766 ) 104,018 (825 ) Corporate securities - - 4,715 (285 ) 4,715 (285 ) $ 31,814 $ (84 ) $ 107,896 $ (1,089 ) $ 139,710 $ (1,173 ) December 31, 2018 Less Than 12 Months 12 Months or More Total Fair Unrealized Fair Unrealized Fair Unrealized (Dollars in thousands) Value Losses Value Losses Value Losses Available for Sale U.S. Government-sponsored securities $ - $ - $ 48,366 $ (588 ) $ 48,366 $ (588 ) Municipal securities 1,701 (12 ) 4,095 (53 ) 5,796 (65 ) Mortgage-backed securities 35,155 (156 ) 150,569 (4,523 ) 185,724 (4,679 ) Corporate securities 1,977 (23 ) 2,596 (404 ) 4,573 (427 ) $ 38,833 $ (191 ) $ 205,626 $ (5,568 ) $ 244,459 $ (5,759 ) Held to Maturity Municipal securities $ 9,163 $ (39 ) $ 46,996 $ (685 ) $ 56,159 $ (724 ) The amortized cost and estimated fair value of investment securities that are available for sale and held to maturity at September 30, 2019, by contractual maturity, are as follows: Available For Sale Amortized Fair (Dollars in thousands) Cost Value Securities maturing in: One year or less $ 32,270 $ 32,285 After one year through five years 65,081 65,322 After five years through ten years 57,322 57,327 After ten years 163,595 164,923 $ 318,268 $ 319,857 Actual maturities may differ from contractual maturities because issuers may have the right to call obligations with or without penalties and other securities may experience pre-payments. As of September 30, 2019, the Company held 170 available for sale investment securities with fair value less than amortized cost compared to 201 at December 31, 2018. In addition, the Company had no held to maturity securities at September 30, 2019, and held 122 held to maturity securities with fair values less than amortized cost at December 31, 2018. Management evaluated these investment securities and determined that the decline in value is temporary and related to the change in market interest rates since purchase. The decline in value is not related to any company or industry specific event. The Company anticipates full recovery of the amortized cost with respect to these securities at maturity, or sooner, in the event of a more favorable market interest rate environment. Note 2 — Investment Securities – continued The Company sold no available for sale securities during the nine months ended September 30, 2019, compared to $500,000 during the nine months ended September 30, 2018, which resulted in a net gain of $336,000. There were no available for sale securities in a nonaccrual status at September 30, 2019 or December 31, 2018. The Company had no held to maturity securities in a nonaccrual status at December 31, 2018.

Including these PCI loans, total non-accrual loans are $4.3 million and $4.5 million at September 30, 2019, and December 31, 2018, respectively. Note 3 — Loans and Allowance for Loan Losses – Continued Troubled debt restructured (“TDR”) loans are summarized as follows: September 30, December 31, (Dollars in thousands) 2019 2018 Accruing troubled debt restructured loans $ 25,452 $ 5,912 Non-accrual troubled debt restructured loans 1,432 1,599 Total troubled debt restructured loans $ 26,884 $ 7,511 There were no PCI TDR non-performing loans as of September 30, 2019 and December 31, 2018. A restructured loan is considered a troubled debt restructuring (“TDR”), if the Company, for economic or legal reasons related to the debtor’s financial difficulties, grants a concession in terms or a below-market interest rate to the debtor that it would not otherwise consider. Each TDR is separately negotiated with the borrower and includes terms and conditions that reflect the borrower’s prospective ability to service the debt as modified. The following tables present TDRs that occurred during the periods presented and the TDRs for which the payment default occurred within twelve months of the restructure date. A default on a TDR results in a transfer to nonaccrual status, a charge-off or a combination of both.

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 Loan Losses – Continued For Consumer loans, the Company generally assigns internal risk grades similar to those described above based on payment performance.

Purchased loans, including loans acquired in business combinations, are recorded at their fair value at the acquisition date. Credit discounts are included in the determination of fair value; therefore, an allowance for loan and lease losses is not recorded at the acquisition date. Acquired loans are evaluated upon acquisition and classified as either purchased credit-impaired (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 $7.5 million at September 30, 2019 and $7.7 million at December 31, 2018. The carrying balance of PCI loans was $4.7 million at September 30, 2019 and $4.7 million at December 31, 2018. The following table presents the changes in the accretable yield for purchased loans for the nine months ended September 30, 2019, and 2018: Nine Months Ended September 30, (Dollars in thousands) 2019 2018 Balance, beginning of period $ 5,884 $ 8,536 Accretion to interest income (1,418 ) (2,165 ) Reclassification from non-accretable difference 96 189 Balance, end of period $ 4,562 $ 6,560 Note 3 — Loans and Allowance for Loan Losses – Continued As of September 30, 2019 and December 31, 2018, the non-accretable difference between the contractually required payments and cash flows expected to be collected were $2.8 million and $2.9 million, respectively. 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 $3.3 million and $5.6 million as of September 30, 2019, and December 31, 2018, respectively. Available lines of credit for loans and credit cards to affiliates were approximately $274,000 and $951,000 as of September 30, 2019, and December 31, 2018, respectively. Deposits from affiliates were $2.9 million and $8.8 million as of September 30, 2019 and December 31, 2018, 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: September 30, December 31, (Dollars in thousands) 2019 2018 Commitments to extend credit, including unsecured commitments of $15,893 and $16,304 as of September 30, 2019 and December 31, 2018, respectively $ 585,871 $ 577,612 Stand-by letters of credit and bond commitments, including unsecured commitments of $576 and $730 as of September 30, 2019 and December 31, 2018, respectively 23,975 22,979 Unused credit card lines, all unsecured 25,353 24,885 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 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 • Level 2 • Level 3 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. Note 5 — Fair Value - Continued The following table presents estimated fair values of the Company’s financial instruments as of September 30, 2019 and December 31, 2018: September 30, 2019 December 31, 2018 Carrying Estimated Carrying Estimated (Dollars in thousands) Level Value Fair Value Value Fair Value Financial Assets: Cash and cash equivalents 1 $ 340,396 $ 340,396 $ 48,547 $ 48,547 Investment securities available for sale 2 309,031 309,031 280,964 280,964 Investment securities available for sale 3 10,826 10,826 - - Investment securities held to maturity 2 - - 50,905 50,364 Investment securities held to maturity 3 - - 14,557 14,402 Non-marketable securities 2 2,623 2,623 2,551 2,551 Loans held for sale 2 19,554 19,554 10,267 10,267 Loans held for investment 3 1,644,676 1,636,124 1,653,657 1,637,617 Financial Liabilities: Total deposits 2 $ 2,101,712 $ 1,889,887 $ 1,877,055 $ 1,675,992 Assets measured on a recurring and non-recurring basis are as follows: (Dollars in thousands) Level 1 Level 2 Level 3 Total As of September 30, 2019 Fair valued on a recurring basis: Investment securities available for sale $ - $ 309,031 $ 10,826 $ 319,857 Fair valued on a non-recurring basis: Impaired loans - - 17,604 17,604 As of December 31, 2018 Fair valued on a recurring basis: Investment securities available for sale $ - $ 280,964 $ - $ 280,964 Fair valued on a non-recurring basis: Impaired loans - - 7,304 7,304

Income Taxes	Note 6 — Income Taxes Income tax expense was $3.4 million and $3.3 million for the three months ended September 30, 2019 and 2018, respectively. The Company’s effective tax rate for the third quarter of 2019 was 23.2% compared with 23.9% in the third quarter of 2018. The tax rate in the third quarter of 2019 is lower than the same quarter in 2018 due primarily to the timing of tax benefits related to tax-deductible stock compensation expense. Income tax expense was $10.1 million and $9.1 million for the nine months ended September 30, 2019 and 2018, respectively. The Company’s effective tax rate for the nine months ended September 30, 2019 was 23.7% compared with 23.4% in the same period a year ago. The tax rate in the nine months ended September 30, 2019 is higher than the same period a year ago due primarily to the timing of tax benefits related to tax-deductible stock compensation expense.

Regulatory Capital Matters	Note 7 — Regulatory Capital Matters The consolidated Tier 1 Leverage ratio increased to 12.64% as of September 30, 2019 from 12.27% at December 31, 2018. Federal Reserve Board Regulations require maintenance of certain minimum reserve balances based on certain average deposits, which, as of September 30, 2019 and December 31, 2018, were $10.7 million and $2.2 million, respectively. 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, plans to limit dividends to amounts that are appropriate to maintain those well-capitalized regulatory capital ratios.

Incentive Share-Based Plan and Other Employee Benefits	Note 8 — Incentive Share-Based Plan and Other Employee Benefits In June 2014, the Board of Directors (“Board”) and 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 800,000 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 nine months ended September 30, 2019, the Company granted 39,401 restricted stock units (“RSU”) at a weighted-average fair value of $29.97 per unit. Additionally, the Company granted options for the purchase of 545 common shares, which have a weighted average exercise price of $27.53 and a weighted average fair value as of the date of grant of $3.61 per share. The options and RSU’s generally vest over periods from one to three years. The Company recorded share-based compensation expense of $796,000 and $683,000 for the nine months ended September 30, 2019 and 2018, respectively.

Accounting Policies [Abstract]
Nature of Operations and Basis of Consolidation	Nature of operations and basis of consolidation — People’s Utah Bancorp, Inc. (“PUB” or the “Company”) is a Utah corporation headquartered in American Fork, Utah. The Company operates all business activities through its wholly-owned banking subsidiary, People’s Intermountain Bank (“PIB” or the “Bank”), which was organized in 1913. The Bank is a Utah state chartered bank. The Bank operates under the jurisdiction of the Utah Department of Financial Institutions, and its deposits are insured by the Federal Deposit Insurance Corporation (“FDIC”). The Bank is not a member of the Federal Reserve System; however, PUB is operated as a bank holding company under the Federal Bank Holding Company Act of 1956 and is the sole shareholder of the Bank. Both PUB and the Bank are subject to periodic examination by applicable federal and state regulatory agencies and file periodic reports and other information with the agencies. The Company considers the Bank to be its sole operating segment. PIB is a community bank that provides highly personalized retail and commercial banking products and services to small and medium sized businesses and to individuals. Products and services are offered primarily through 26 retail branch locations throughout Utah and southern Idaho. PIB has three banking divisions, Bank of American Fork, Lewiston State Bank, and People’s Town & Country Bank; and a mortgage division, People’s Intermountain Bank Mortgage. The Bank offers a full range of short-term to long-term commercial, personal and mortgage loans. Commercial loans include secured and unsecured loans for working capital (including inventory and accounts receivable), business expansion (including acquisition of real estate and improvements), and purchase of equipment and machinery. Consumer loans include secured and unsecured loans to finance automobiles, home improvements, and personal investments. The Bank also offers mortgage loans secured by personal residences. The Bank offers a full range of deposit services typically available in most financial institutions, including checking accounts, savings accounts, and time deposits. The Bank solicits these accounts from individuals, businesses, associations and organizations, and governmental entities. 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 preparing these financial statements, the Company has evaluated events and transactions subsequent to September 30, 2019, for potential recognition or disclosure. 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. Certain reclassifications have been made to the 2018 Consolidated Financial Statements and/or schedules to conform to the 2019 presentation. These reclassifications may have affected certain ratios for the prior periods. The effect of these reclassifications is considered immaterial. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect amounts reported in the financial statements. Various elements of the Company’s accounting policies, by their nature, are inherently subject to estimation techniques, valuation assumptions and other subjective assessments. In particular, management has identified several accounting policies that, due to the judgments, estimates and assumptions inherent in those policies, are significant to an understanding of the Company’s financial statements. These policies relate to (i) the methodology for the recognition of interest income, (ii) determination of the provision and allowance for loan losses, (iii) the valuation of financial assets and liabilities recorded at fair value, including other-than-temporary impairment (OTTI) losses, (iv) the valuation of intangibles, such as goodwill, core deposit intangibles (CDI) and mortgage servicing rights, (v) the valuation of real estate held for sale, (vi) the valuation of assets and liabilities acquired in business combinations and subsequent recognition of related income and expense, and (vii) the valuation or recognition of deferred tax assets and liabilities. These policies and judgments, estimates and assumptions are described in greater detail in subsequent notes to the Consolidated Financial Statements and Management’s Discussion and Analysis of Financial Condition and Results of Operations (Critical Accounting Policies) in our Annual Report on Form 10-K for the year ended December 31, 2018 filed with the SEC (2018 Form 10-K). There have been no significant changes in our application of these accounting policies during the first nine months of 2019, except as described later in Note 1. The information included in this Form 10-Q should be read in conjunction with our 2018 Form 10-K. Interim results are not necessarily indicative of results for a full year or any other interim period.
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 restricted stock units (“RSU”).
Reclassifications	Reclassifications — Certain amounts in the prior period’s financial statements have been reclassified to conform to the current period’s presentation.
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 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. This ASU is effective for fiscal years beginning after December 15, 2019 and interim periods within those fiscal years. The amendments in this ASU should be applied either retrospectively or prospectively to all implementation costs incurred after the date of adoption. Adoption of ASU 2018-15 is not expected to 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. This 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 the disclosure requirements to require 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. An entity is permitted to early adopt any removed or modified disclosures upon issuance of this ASU and delay adoption of the additional disclosures until their effective date. Adoption of ASU 2018-13 is not expected to have a material impact on the Company’s Consolidated Financial Statements. In June 2016, the FASB issued 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 (“CECL”) measurement to estimate the allowance for credit losses (“ACL”) 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 purchase credit deteriorated (“PCD”) 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 is 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 SEC. 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, the Company’s public float was $466 million and annual revenues for 2018 were $130 million. The Company is not an SRC and will be required to adopt the ASU effective January 1, 2020. Note 1 — Basis of Presentation and Significant Accounting Policies – Continued The implementation process includes evaluation of technical accounting topics; developing, validating and implementing models and methodologies used to calculate CECL; updating ACL documentation; validating internal controls; and overall operational readiness for adoption of the ASU. The Company is currently running new models and processes in parallel with existing models and processes under current accounting guidance in advance of the January 1, 2020 effective date. These parallel runs will focus on technical functionality of the CECL calculation, operational execution of the end-to-end process, as well as disclosure requirements. The Company has established a project team and a steering committee to provide cross-functional governance over and make key decisions relating to the project plan and the parallel runs. The Company intends to recognize an ACL for available for sale debt securities. The ACL on available for sale debt securities will be subject to a limitation based on the fair value of the debt securities. Based on the credit quality of existing debt securities, the Company does not expect the ACL for debt securities to be material. The Company expects to use the weighted average remaining maturity (“WARM”) approach, adjusted for prepayments, to calculate CECL. As described in the FASB Staff Question and Answers, the Company intends to use a qualitative approach to adjust historical loss information for current conditions and for reasonable and supportable forecasts, and then immediately revert to historical credit losses. As noted in section ASU 320-20-30-9, “An entity shall not rely solely on past events to estimate expected credit losses. When an entity uses historical loss information, it shall consider the need to adjust historical information to reflect the extent to which 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. The adjustments to historical loss information may be qualitative in nature and should reflect changes related to relevant data (such as changes in unemployment rates, property values, commodity values, delinquency, or other factors that are associated with credit losses on the financial asset or in the group of financial assets).” The Company is currently in the process of evaluating the impact of CECL on its earnings, financial position, and regulatory capital amounts and ratios related to loans. The Company expects its ACL to increase upon adoption, because the ACL will be required to cover the full remaining expected life of the portfolio, rather than the incurred loss model under current U.S. GAAP. In addition, a portion of the increase will be due to PCI loans that will be reclassified as PCD loans with the credit related non-accretable discount increasing both ACL and loan balances, but not retained earnings. However, accretable discounts held on non-PCD loans are not allowed to be moved to ACL as part of the adoption of this ASU. The Company will be required to set aside additional ACL for non-PCD loans through retained earnings upon adoption. The Company will continue to hold accretable discounts that will be recorded to interest income over the remaining life of non-PCD loans as well as a similar amount in ACL. 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 effective 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 the Company. The ultimate effect of CECL on the Company’s ACL will depend on the size and composition of the loan portfolio; the loan portfolio’s credit quality and economic conditions at the time of adoption; and any refinements to models, methodologies, and other key assumptions used. At adoption, the Company will have a cumulative effect adjustment to retained earnings for the change in the ACL, which the Company expects to negatively impact regulatory capital amounts and ratios. An increase in the Company’s ACL will result in a decrease in regulatory capital amounts and ratios. Bank regulatory agencies have provided regulatory capital relief for an initial capital decrease from the adoption of this ASU by allowing a phased adoption over three years, on a straight-line basis, which the Company expects to utilize. In February 2016, FASB issued ASU No. 2016-02, Leases (Topic 842). The amendments in this ASU require lessees to recognize the following for all leases (with the exception of short-term) at the commencement date: a lease liability, which is a lessee‘s obligation to make lease payments arising from a lease, measured on a discounted basis; and a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. The amendments in this ASU leave lessor accounting largely unchanged, although certain targeted improvements were made to align lessor accounting with the lessee accounting model. This ASU simplifies the accounting for sale and leaseback transactions primarily because lessees must recognize lease assets and lease liabilities. Note 1 — Basis of Presentation and Significant Accounting Policies – Continued Lessees will no longer be provided with a source of off-balance sheet financing. The Company adopted ASU No. 2016-02 effective January 1, 2019. The Company elected the transition option provided in ASU No. 2018-11 and applied the modified retrospective approach. The Company also elected certain relief options for practical expedients: the option to not separate lease and non-lease components and instead to account for them as a single lease component; and the option to not recognize right-of-use assets and lease liabilities that arise from short-term leases (i.e. leases with terms of twelve months or less). The Company has eight real property leases under non-cancelable operating leases, four of which are subject to this ASU that results in the recognition of right of use assets and lease liabilities. All of the Company’s equipment is owned or on short-term leases. The Company compiled a complete inventory of arrangements containing leases and analyzed the lease data necessary to meet the new requirements. The Company has recorded a $2.2 million right of use asset and a $2.2 million lease liability on its Consolidated Balance Sheets.
