Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Principles of Consolidation and Basis of Presentation The accompanying unaudited condensed consolidated financial statements include the accounts of Univest Financial Corporation (the Corporation) and its wholly owned subsidiaries. The Corporation’s direct subsidiary is Univest Bank and Trust Co. (the Bank). All significant intercompany balances and transactions have been eliminated in consolidation. The unaudited condensed consolidated financial statements included herein have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (the SEC). Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles (U.S. GAAP) have been condensed or omitted pursuant to such rules and regulations for interim financial information. The accompanying unaudited consolidated financial statements reflect all adjustments which are of a normal recurring nature and are, in the opinion of management, necessary for a fair presentation of the financial statements for the interim periods presented. Certain prior period amounts have been reclassified to conform to the current-period presentation. Operating results for the three-month period ended March 31, 2021 are not necessarily indicative of the results that may be expected for the year ended December 31, 2021 or for any other period. These unaudited condensed consolidated financial statements should be read in conjunction with the audited financial statements and the notes thereto included in the registrant’s Annual Report on Form 10-K for the year ended December 31, 2020, which was filed with the SEC on February 26, 2021. Use of Estimates The preparation of the unaudited condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant changes include fair value measurement of investment securities available-for-sale and the determination of the allowance for credit losses. Accounting Pronouncements Adopted in 2021 In August 2018, the FASB issued ASU No. 2018-14, " Compensation – Retirement Benefits – Defined Benefit Plans – General (Subtopic 715-20): Disclosure Framework – Changes to the Disclosure Requirements for Defined Benefit Plans." The amendments in this ASU modify the disclosure requirements for employers that sponsor defined benefit plans or other postretirement plans. Disclosures removed by this ASU include the following: 1) amounts in accumulated other comprehensive income expected to be recognized in net periodic benefit costs over the next fiscal year; 2) the amount and timing of plan assets expected to be returned to the employer; and 3) the effects of a one percentage point change in assumed health care cost trend rates on the net periodic benefit costs and the benefit obligation for postretirement health care benefits. Additional disclosures required by this ASU include: 1) the weighted-average interest crediting rates used in an entity's cash balance pension plans and other similar plans and 2) explanations for reasons for significant changes in the benefit obligation or plan assets. These amendments are to be applied retrospectively. This ASU became effective on January 1, 2021 for the Corporation. The adoption of this ASU did not have a material impact on the Corporation's financial statement disclosures but will result in the elimination of certain disclosures for retirement plans and other postretirement benefits in the Form 10-K. In December 2019, the FASB issued ASU No. 2019-12, " Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes." The ASU adds new guidance to simplify accounting for income taxes, changes the accounting for certain income tax transactions and makes minor improvements to the codification. This ASU became effective on January 1, 2021 for the Corporation. The adoption of this ASU did not have a material impact on the Corporation's financial statements. Recent Accounting Pronouncements Yet to Be Adopted In January 2020, the FASB issued ASU No. 2020-01, " Investments—Equity Securities (Topic 321): Investments—Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815): Clarifying the Interactions between Topic 321, Topic 323, and Topic 815." This ASU 2020-01 clarifies the interactions between ASC 321, ASC 323 and ASC 815 and addresses accounting for the transition into and out of the equity method and measuring certain purchased options and forward contracts to acquire investments. This ASU is effective for fiscal years beginning after December 15, 2021 or January 1, 2022 for the Corporation. The Corporation does not expect the adoption of this ASU will have a material impact on the Corporation's financial statements. In March 2020, the FASB issued ASU No. 2020-04, " Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting." The guidance allows for companies to: (1) account for certain contract modifications as a continuation of the existing contract without additional analysis; (2) continue hedge accounting when certain critical terms of a hedging relationship change and assess effectiveness in ways that disregard certain potential sources of ineffectiveness; and (3) make a one-time sale and/or transfer of certain debt securities from held-to-maturity to available-for-sale or trading. This ASU is available for adoption effective immediately, or as of January 1, 2020 or any date thereafter for the Corporation, and applies prospectively to contract modifications and hedging relationships. The one-time election to sell and/or transfer debt securities classified as held-to-maturity may be made at any time after March 12, 2020. The Corporation anticipates adopting this ASU and will continue to analyze the provisions of the ASU in connection with ongoing procedures to monitor the work of the Alternative Rates Committee of the FRB and Federal Reserve Bank of New York in identifying an alternative U.S. dollar reference interest rate. It is too early to predict whether a new rate index replacement and the adoption of the ASU will have a material impact on the Corporation's financial statements. In August 2020, the FASB issued ASU No. 2020-06, "Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40) ." This guidance simplifies the accounting for convertible debt and convertible preferred stock by removing the requirements to separately present certain conversion features in equity. In addition, the amendments in the ASU also simplify the guidance in ASC 815-40 by removing certain criteria that must be satisfied in order to classify a contract as equity, which is expected to decrease the number of freestanding instruments and embedded derivatives accounted for as assets or liabilities. Finally, the amendments revise the guidance on calculating earnings per share, requiring use of the if-converted method for all convertible instruments and require entities to presume share settlement for purposes of calculating diluted EPS when an instrument may be settled in cash or shares. This ASU is effective for fiscal years beginning after December 15, 2021 or January 1, 2022 for the Corporation. The Corporation does not expect the adoption of this ASU will have a material impact on the Corporation's financial statements. In January 2021, the FASB issued ASU No. 2021-01, which refines the scope of ASU No. 2020-04, " Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting",

Securities with a carrying value of $248.9 million and $249.6 million at March 31, 2021 and December 31, 2020, respectively, were pledged to secure public funds deposits and other contractual obligations. In addition, securities of $15.5 million and $32.6 million were pledged to secure credit derivatives and interest rate swaps at March 31, 2021 and December 31, 2020, respectively. See Note 11, "Derivative Instruments and Hedging Activities" for additional information. The following table presents information related to sales of securities available-for-sale during the three months ended March 31, 2021 and 2020: Three Months Ended March 31, (Dollars in thousands) 2021 2020 Securities available-for-sale: Proceeds from sales $ 1,563 $ 62,276 Gross realized gains on sales 65 709 Gross realized losses on sales — 14 Tax expense related to net realized gains on sales 14 146 At March 31, 2021 and December 31, 2020, there were no reportable investments in any single issuer representing more than 10% of shareholders’ equity. The following table shows the fair value of securities that were in an unrealized loss position for which an allowance for credit losses has not been recorded at March 31, 2021 and December 31, 2020, by the length of time those securities were in a continuous loss position.

These holdings were comprised of two federal agency mortgage-backed securities, which are U.S. government entities and agencies and are either explicitly or implicitly guaranteed by the U.S. government, are highly rated by major rating agencies and have a long history of no credit losses. The Corporation did not recognize any credit losses on held-to-maturity debt securities for the three months ended March 31, 2021 or March 31, 2020. Accrued interest receivable on held-to-maturity debt securities totaled $357 thousand at March 31, 2021 and is included within Accrued interest receivable and other assets on the condensed consolidated balance sheet. This amount is excluded from the estimate of expected credit losses. At March 31, 2021, the fair value of available-for-sale securities in an unrealized loss position for which an allowance for credit losses has not been recorded was $77.5 million, including unrealized losses of $1.9 million. These holdings were comprised of sixteen federal agency mortgage-backed securities, which are U.S. government entities and agencies and are either explicitly or implicitly guaranteed by the U.S. government, are highly rated by major rating agencies and have a long history of no credit losses. The Corporation does not intend to sell the securities in an unrealized loss position and is unlikely to be required to sell these securities before a recovery of fair value, which may be maturity. The Corporation concluded that the decline in fair value of these securities was not indicative of a credit loss. Accrued interest receivable on available-for-sale debt securities totaled $602 thousand at March 31, 2021 and is included within Accrued interest receivable and other assets on the condensed consolidated balance sheet. This amount is excluded from the estimate of expected credit losses. The table below presents a rollforward by major security type for the three months ended March 31, 2021 of the allowance for credit losses on securities available-for-sale. (Dollars in thousands) Corporate Bonds Three months ended March 31, 2021 Securities Available-for-Sale Beginning balance $ (869) Additions for securities for which no previous expected credit losses were recognized (19) Change in securities for which a previous expected credit loss was recognized 403 Ending balance $ (485) Three months ended March 31, 2020 Securities Available-for-Sale Beginning balance $ — Adjustment to initially apply ASU No. 2016-13 for CECL (300) Additions for securities for which no previous expected credit losses were recognized (25) Change in securities for which a previous expected credit loss was recognized (572) Ending balance $ (897) At March 31, 2021, the fair value of available-for-sale securities in an unrealized loss position for which an allowance for credit losses has been recorded was $52.6 million, including unrealized losses of $820 thousand, and allowance for credit losses of $485 thousand. These holdings were comprised of thirteen investment grade corporate bonds which fluctuate in value based on changes in market conditions. For these securities, fluctuations were primarily due to changes in the interest rate environment. The Corporation does not have the intent to sell these securities and it is not likely that it will be required to sell the securities before their anticipated recovery. The underlying issuers continue to make timely principal and interest payments on the securities. The reversal of the provision for credit losses of $403 thousand for the three months ended March 31, 2021 was primarily related to the improvement in fair value of six underlying securities that are tied to the 10-year swap curve which had significantly steepened during the quarter. The Corporation recognized a $115 thousand net gain and a $268 thousand net loss on equity securities during the three months ended March 31, 2021 and 2020, respectively, in other noninterest income. There were no sales of equity securities during the three months ended March 31, 2021 or March 31, 2020.

Loans with a relationship balance of less than $1 million are reviewed when necessary based on their performance, primarily when such loans are delinquent. Loans with relationships greater than $1 million are reviewed at least annually. Loan relationships with a higher risk profile or classified as special mention or substandard are reviewed at least quarterly. The Corporation reviews credit quality indicators on at least an annual basis and last completed this review in conjunction with the period ended December 31, 2020. The following is a description of the internal risk ratings and the likelihood of loss related to the credit quality of Commercial, financial and agricultural loans, Paycheck Protection Program loans, Real-estate commercial loans, Real-estate construction loans and Real-estate residential secured for a business purpose loans. 1. Pass—Loans considered satisfactory with no indications of deterioration 2. Special Mention—Potential weakness that deserves management's close attention 3. Substandard—Well-defined weakness or weaknesses that jeopardize the liquidation of the debt 4. Doubtful—Collection or liquidation in-full, on the basis of current existing facts, conditions and values, highly questionable and improbable Based on the most recent analysis performed, the following table presents the recorded investment in loans and leases held for investment for Commercial, financial and agricultural loans, Paycheck Protection Program loans, Real-estate commercial loans, Real-estate construction loans and Real-estate residential secured for a business purpose loans by credit quality indicator at March 31, 2021 and December 31, 2020.

Share-based Payment Arrangement [Abstract]
Share-Based Incentive Plan	Stock-Based Incentive Plan The Corporation maintains the 2013 Long-Term Incentive Plan, which replaced the expired 2003 Long-Term Incentive Plan. In December 2018, the Corporation's Board of Directors approved an Amended and Restated Univest 2013 Long-Term Incentive Plan (the Plan) to permit the issuance of restricted stock units. Beginning in 2019, the Corporation issued to directors and employees ("grantees") restricted stock units rather than restricted stock awards or stock options, which were issued to grantees in prior reporting periods. Restricted stock units differ from restricted stock awards in that Corporation stock is not issued to grantees at the date of the grant and the grantee does not have voting or dividend rights during the vesting period. In the following schedules, issued restricted stock units have been combined with restricted stock awards, as the determination of the value at the grant date and methodology for recording stock-based compensation expense is the same. The following is a summary of the Corporation's stock option activity and related information for the three months ended March 31, 2021: (Dollars in thousands, except per share data) Shares Under Option Weighted Average Exercise Price Per Share Weighted Average Remaining Contractual Life (Years) Aggregate Intrinsic Value at March 31, 2021 Outstanding at December 31, 2020 453,785 $ 25.06 Forfeited (9,500) 28.33 Exercised (36,286) 20.90 Outstanding at March 31, 2021 407,999 25.35 5.6 $ 1,322 Exercisable at March 31, 2021 407,999 25.35 5.6 1,322 The following is a summary of nonvested stock options at March 31, 2021 including changes during the three months then ended: (Dollars in thousands, except per share data) Nonvested Stock Options Weighted Average Grant Date Fair Value Nonvested stock options at December 31, 2020 49,771 $ 6.46 Vested (49,771) 6.46 Nonvested stock options at March 31, 2021 — — The Corporation did not issue stock options during the three months ended March 31, 2021 or March 31, 2020.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments and Hedging Activities	Derivative Instruments and Hedging Activities Interest Rate Swaps The Corporation periodically uses interest rate swap agreements to modify interest rate characteristics from variable to fixed or fixed to variable in order to reduce the impact of interest rate changes on future net interest income. The Corporation’s credit exposure on interest rate swaps includes fair value and any collateral that is held by a third party. In 2014, the Corporation entered into an amortizing interest rate swap classified as a cash flow hedge with a notional amount of $20.0 million to hedge a portion of the debt financing of a pool of 10-year fixed rate loans with balances totaling $29.1 million, at time of the hedge, that were originated in 2013. A brokered money market demand account with a balance exceeding the amortizing interest rate swap balance is being used for the cash flow hedge. Under the terms of the swap agreement, the Corporation pays a fixed rate of 2.10% and receives a floating rate of one-month LIBOR. The swap matures in November 2022. The Corporation performed an assessment of the hedge for effectiveness at the inception of the hedge and on a recurring basis to determine that the derivative has been and is expected to continue to be highly effective in offsetting changes in cash flows of the hedged item. At March 31, 2021, approximately $233 thousand in net deferred losses, net of tax, recorded in accumulated other comprehensive loss are expected to be reclassified into earnings during the next twelve months. This amount could differ from amounts actually recognized due to changes in interest rates, hedge de-designations, and the addition of other hedges subsequent to March 31, 2021. At March 31, 2021, the notional amount of the interest rate swap was $15.3 million and the fair value was a liability of $450 thousand. The Corporation has an interest rate swap with a current notional amount of $147 thousand, for a 15-year fixed rate loan that is earning interest at 7.43%. The Corporation pays a fixed rate of 7.43% and receives a floating rate based on the one-month LIBOR plus 224 basis points. The swap matures in April 2022. The interest rate swap is carried at fair value in accordance with FASB ASC 815 "Derivatives and Hedging." The loan is carried at fair value under the fair value option as permitted by FASB ASC 825 "Financial Instruments." Credit Derivatives The Corporation has agreements with third-party financial institutions whereby the third-party financial institution enters into interest rate derivative contracts with loan customers referred to them by the Corporation. By the terms of the agreements, the third-party financial institution has recourse to the Corporation for any exposure created under each swap contract in the event the customer defaults on the swap agreement and the agreement is in a paying position to the third-party financial institution. These transactions represent credit derivatives and are a customary arrangement that allows the Corporation to provide access to interest rate swap transactions for customers without issuing the swap. At March 31, 2021, the Corporation reported 110 variable-rate to fixed-rate interest rate swap transactions between the third-party financial institution and customers with a current notional amount of $707.3 million and remaining maturities ranging from 12 months to 10 years. At March 31, 2021, the fair value of the Corporation's interest rate swap credit derivatives was a liability of $271 thousand. At March 31, 2021, the fair value of the swaps to the customers was a net liability of $15.5 million and these swaps were in paying positions to the third-party financial institution. The maximum potential payments by the Corporation to the third-party financial institution under these credit derivatives are not estimable as they are contingent on future interest rates and the agreement does not provide for a limitation of the maximum potential payment amount. Mortgage Banking Derivatives Derivative loan commitments represent agreements for delayed delivery of financial instruments in which the buyer agrees to purchase and the seller agrees to deliver, at a specified future date, a specified instrument at a specified price or yield. The Corporation’s derivative loan commitments are commitments to sell loans secured by 1-to 4-family residential properties whose predominant risk characteristic is interest rate risk. Derivatives Tables The following table presents the notional amounts and fair values of derivatives designated as hedging instruments recorded on the condensed consolidated balance sheets at March 31, 2021 and December 31, 2020.

Fair Value Disclosures

Fair Value Disclosures	3 Months Ended

Fair Value Disclosures [Abstract]
Fair Value Disclosures	Fair Value Disclosures Fair value is the price that would be received to sell an asset or paid to transfer a liability (an exit price) in an orderly transaction between market participants at the measurement date. The Corporation determines the fair value of financial instruments based on the fair value hierarchy. The Corporation maximizes the use of observable inputs and minimizes the use of unobservable inputs when measuring fair value. Observable inputs are inputs that market participants would use in pricing the asset or liability developed based on market data obtained from sources independent of the Corporation. Unobservable inputs are inputs that reflect the Corporation’s assumptions that market participants would use in pricing the asset or liability based on the best information available in the circumstances, including assumptions about risk. Three levels of inputs are used to measure fair value. A financial instrument’s level within the fair value hierarchy is based on the lowest level of input significant to the fair value measurement. Level 1: Valuations are based on quoted prices in active markets for identical assets or liabilities that the Corporation can access at the measurement date. Since valuations are based on quoted prices that are readily and regularly available in an active market, valuation of these products does not entail a significant degree of judgment. Level 2: Valuations are based on quoted prices in markets that are not active or for which all significant inputs are observable, either directly or indirectly. Level 3: Valuations are based on inputs that are unobservable and significant to the overall fair value measurement. Assets and liabilities utilizing Level 3 inputs include: financial instruments whose value is determined using pricing models, discounted cash-flow methodologies, or similar techniques, as well as instruments for which the fair value calculation requires significant management judgment or estimation. Following is a description of the valuation methodologies used for instruments measured at fair value on a recurring basis, as well as the general classification of such instruments pursuant to the valuation hierarchy. Investment Securities Where quoted prices are available in an active market for identical instruments, investment securities are classified within Level 1 of the valuation hierarchy. Level 1 investment securities include U.S. Treasury securities, most equity securities and money market mutual funds. Mutual funds are registered investment companies which are valued at net asset value of shares on a market exchange at the end of each trading day. Level 2 of the valuation hierarchy includes securities issued by U.S. Government sponsored enterprises, mortgage-backed securities, collateralized mortgage obligations, corporate and municipal bonds and certain equity securities. If quoted market prices are not available, then fair values are estimated by using pricing models, quoted prices of securities with similar characteristics or discounted cash flows. In cases where there is limited activity or less transparency around inputs to the valuation, investment securities are classified within Level 3 of the valuation hierarchy. Fair values for securities are determined using independent pricing services and market-participating brokers. The Corporation’s independent pricing service utilizes evaluated pricing models that vary by asset class and incorporate available trade, bid and other market information for structured securities, cash flow and, when available, loan performance data. Because many fixed income securities do not trade on a daily basis, the pricing service’s evaluated pricing applications apply information as applicable through processes, such as benchmarking of like securities, sector groupings, and matrix pricing, to prepare evaluations. If at any time, the pricing service determines that it does not have sufficient verifiable information to value a particular security, the Corporation will utilize valuations from another pricing service. Management has a sufficient understanding of the third-party service’s valuation models, assumptions and inputs used in determining the fair value of securities to enable management to maintain an appropriate system of internal control. On a quarterly basis, the Corporation reviews changes, as submitted by the pricing service, in the market value of its security portfolio. Individual changes in valuations are reviewed for consistency with general interest rate movements and any known credit concerns for specific securities. If, upon the Corporation’s review or in comparing with another service, a material difference between pricing evaluations were to exist, the Corporation may submit an inquiry to the current pricing service regarding the data used to determine the valuation of a particular security. If the Corporation determines there is market information that would support a different valuation than from the current pricing service’s evaluation, the Corporation may utilize and change the security's valuation. There were no material differences in valuations noted at March 31, 2021. Loans Held for Sale The fair value of our loans held for sale is based on estimates using Level 2 inputs. These inputs are based on pricing information obtained from wholesale mortgage banks and brokers and applied to loans with similar interest rates and maturities. Derivative Financial Instruments The fair values of derivative financial instruments are based upon the estimated amount the Corporation would receive or pay to terminate the contracts or agreements, taking into account current interest rates and, when appropriate, the current creditworthiness of the counterparties. Interest rate swaps and mortgage banking derivative financial instruments are classified within Level 2 of the valuation hierarchy. Credit derivatives are valued based on credit worthiness of the underlying borrower which is a significant unobservable input and therefore classified in Level 3 of the valuation hierarchy. One commercial loan associated with an interest rate swap is classified in Level 3 of the valuation hierarchy at March 31, 2021 since lending credit risk is not an observable input for this loan. The unrealized gain on the one loan was $4 thousand at March 31, 2021. Contingent Consideration Liability The Corporation estimates the fair value of the contingent consideration liability by using a discounted cash flow model of future contingent payments based on projected revenue related to the acquired business. The estimated fair value of the contingent consideration liability is reviewed on a quarterly basis and any valuation adjustments resulting from a change of estimated future contingent payments based on projected revenue of the acquired business affecting the contingent consideration liability will be recorded through noninterest expense. Due to the significant unobservable input related to the projected revenue, the contingent consideration liability is classified within Level 3 of the valuation hierarchy. An increase in the projected revenue may result in a higher fair value of the contingent consideration liability. Alternatively, a decrease in the projected revenue may result in a lower estimated fair value of the contingent consideration liability. The following table presents the assets and liabilities measured at fair value on a recurring basis at March 31, 2021 and December 31, 2020, classified using the fair value hierarchy: At March 31, 2021 (Dollars in thousands) Level 1 Level 2 Level 3 Assets/ Assets: Available-for-sale securities: State and political subdivisions $ — $ 10,210 $ — $ 10,210 Residential mortgage-backed securities — 133,391 — 133,391 Collateralized mortgage obligations — 4,657 — 4,657 Corporate bonds — 80,971 9,600 90,571 Total available-for-sale securities — 229,229 9,600 238,829 Equity securities: Equity securities - financial services industry 933 — — 933 Money market mutual funds 2,591 — — 2,591 Total equity securities 3,524 — — 3,524 Loans* — — 152 152 Loans held for sale — 22,636 — 22,636 Interest rate locks with customers* — 1,163 — 1,163 Forward loan sale commitments* — 1,222 — 1,222 Total assets $ 3,524 $ 254,250 $ 9,752 $ 267,526 Liabilities: Contingent consideration liability $ — $ — $ 28 $ 28 Interest rate swaps* — 455 — 455 Credit derivatives* — — 271 271 Total liabilities $ — $ 455 $ 299 $ 754 * Such financial instruments are recorded at fair value as further described in Note 11, "Derivative Instruments and Hedging Activities." The $9.6 million of corporate bonds was comprised of one investment grade bond and the Corporation utilizes a third party to estimate fair value. The value is derived from a discounted cash flow analysis which utilizes a probability of default input. The $271 thousand of credit derivatives liability represents the Credit Valuation Adjustment (CVA), which is obtained from real-time financial market data, of 110 interest rate swaps with a current notional amount of $707.3 million. The March 31, 2021 CVA assumes a zero-deal recovery percentage based on the most recent index credit curve.

Cash and short-term interest-earning assets are classified within Level 1 in the fair value hierarchy. Held-to-maturity securities: Fair values for the held-to-maturity investment securities are estimated by using pricing models or quoted prices of securities with similar characteristics and are classified in Level 2 in the fair value hierarchy. Federal Home Loan Bank, Federal Reserve Bank and other stock: It is not practical to determine the fair values of Federal Home Loan Bank, Federal Reserve Bank and other stock, due to restrictions placed on their transferability. Loans held for sale: Loans held for sale are carried at the lower of cost or estimated fair value. The fair value of the Corporation’s mortgage loans held for sale are generally determined using a pricing model based on current market information obtained from external sources, including interest rates, bids or indications provided by market participants on specific loans that are actively marketed for sale. These loans are primarily residential mortgage loans and are generally classified in Level 2 due to the observable pricing data. Loans and leases held for investment: The fair values for loans and leases held for investment are estimated using discounted cash flow analyses, using a discount rate based on current interest rates at which similar loans with similar terms would be made to borrowers, adjusted as appropriate to consider credit, liquidity and marketability factors to arrive at a fair value that represents the Corporation's exit price at which these instruments would be sold or transferred. Loans and leases are classified within Level 3 in the fair value hierarchy since credit risk is not an observable input. Individually analyzed loans and leases held for investment: For individually analyzed loans and leases, the Corporation uses a variety of techniques to measure fair value, such as using the current appraised value of the collateral, agreements of sale, discounting the contractual cash flows, and analyzing market data that the Corporation may adjust due to specific characteristics of the loan/lease or collateral. At March 31, 2021, individually analyzed loans held for investment had a carrying amount of $29.8 million with a valuation allowance of $281 thousand. At December 31, 2020, individually analyzed loans held for investment had a carrying amount of $31.5 million with a valuation allowance of $585 thousand. The Corporation had no individually analyzed leases at March 31, 2021 or December 31, 2020. Servicing rights: The Corporation estimates the fair value of servicing rights using discounted cash flow models that calculate the present value of estimated future net servicing income. The model uses readily available prepayment speed assumptions for the interest rates of the portfolios serviced. Servicing rights are classified within Level 3 in the fair value hierarchy based upon management's assessment of the inputs. The Corporation reviews the servicing rights portfolio on a quarterly basis for impairment and the servicing rights are carried at the lower of amortized cost or estimated fair value. At March 31, 2021, servicing rights had a net carrying amount of $7.0 million, which included a valuation allowance of $1 thousand. At December 31, 2020, servicing rights had a net carrying amount of $6.5 million, which included a valuation allowance of $87 thousand. Goodwill and other identifiable assets: Certain non-financial assets subject to measurement at fair value on a non-recurring basis include goodwill and other identifiable intangible assets. During the three months ended March 31, 2021, there were no required valuation adjustments of goodwill and other identifiable intangible assets. Other real estate owned: Other real estate owned (OREO) represents properties that the Corporation has acquired through foreclosure by either accepting a deed in lieu of foreclosure, or by taking possession of assets that were used as loan collateral. The Corporation reports OREO at the lower of cost or fair value less cost to sell, adjusted periodically based on a current appraisal or an executed agreement of sale. Capital improvement expenses associated with the construction or repair of the property are capitalized as part of the cost of the OREO asset. Write-downs and any gain or loss upon the sale of OREO is recorded in other noninterest income. OREO is reported in other assets on the condensed consolidated balance sheet. During the three months ended March 31, 2021, three commercial real estate properties were transferred to OREO with a carrying balance of $126 thousand. At March 31, 2021 and December 31, 2020, OREO had a carrying amount of $7.5 million and $7.4 million, respectively. Other real estate owned is classified within Level 3 of the valuation hierarchy due to the unique characteristics of the collateral for each loan. Deposit liabilities: The fair values for demand and savings accounts, with no stated maturities, is the amount payable on demand at the reporting date (carrying value) and are classified within Level 1 in the fair value hierarchy. The fair values for time deposits with fixed maturities are estimated by discounting the final maturity using interest rates currently offered for deposits with similar remaining maturities. Time deposits are classified within Level 2 in the fair value hierarchy. Short-term borrowings: The fair value of short-term borrowings are estimated using current market rates for similar borrowings and are classified within Level 2 in the fair value hierarchy. Long-term debt: The fair value of long-term debt is estimated by using discounted cash flow analysis, based on current market rates for debt with similar terms and remaining maturities. Long-term debt is classified within Level 2 in the fair value hierarchy.

Segment Reporting [Abstract]
Segment Reporting	Segment Reporting At March 31, 2021, the Corporation has three reportable business segments: Banking, Wealth Management and Insurance. The Corporation determines the segments based primarily upon product and service offerings, through the types of income generated and the regulatory environment. This is strategically how the Corporation operates and has positioned itself in the marketplace. Accordingly, significant operating decisions are based upon analysis of each of these segments. The parent holding company and intercompany eliminations are included in the "Other" segment. Each segment generates revenue from a variety of products and services it provides. Examples of products and services provided for each reportable segment are indicated as follows: ● The Banking segment provides financial services to individuals, businesses, municipalities and nonprofit organizations. These services include a full range of banking services such as deposit taking, loan origination and servicing, mortgage banking, other general banking services and equipment lease financing. ● The Wealth Management segment offers investment advisory, financial planning, trust and brokerage services. The Wealth Management segment serves a diverse client base of private families and individuals, municipal pension plans, retirement plans, trusts and guardianships. ● The Insurance segment includes a full-service insurance brokerage agency offering commercial property and casualty insurance, employee benefit solutions, personal insurance lines and human resources consulting. The following table provides total assets by reportable business segment as of the dates indicated.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	3 Months Ended

Accounting Policies [Abstract]
Principles of Consolidation	Principles of Consolidation and Basis of Presentation The accompanying unaudited condensed consolidated financial statements include the accounts of Univest Financial Corporation (the Corporation) and its wholly owned subsidiaries. The Corporation’s direct subsidiary is Univest Bank and Trust Co. (the Bank). All significant intercompany balances and transactions have been eliminated in consolidation. The unaudited condensed consolidated financial statements included herein have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (the SEC). Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. generally accepted accounting principles (U.S. GAAP) have been condensed or omitted pursuant to such rules and regulations for interim financial information. The accompanying unaudited consolidated financial statements reflect all adjustments which are of a normal recurring nature and are, in the opinion of management, necessary for a fair presentation of the financial statements for the interim periods presented. Certain prior period amounts have been reclassified to conform to the current-period presentation. Operating results for the three-month period ended March 31, 2021 are not necessarily indicative of the results that may be expected for the year ended December 31, 2021 or for any other period. These unaudited condensed consolidated financial statements should be read in conjunction with the audited financial statements and the notes thereto included in the registrant’s Annual Report on Form 10-K for the year ended December 31, 2020, which was filed with the SEC on February 26, 2021.
Use of Estimates	Use of Estimates The preparation of the unaudited condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. Material estimates that are particularly susceptible to significant changes include fair value measurement of investment securities available-for-sale and the determination of the allowance for credit losses.
Recent Accounting Pronouncements	Accounting Pronouncements Adopted in 2021 In August 2018, the FASB issued ASU No. 2018-14, " Compensation – Retirement Benefits – Defined Benefit Plans – General (Subtopic 715-20): Disclosure Framework – Changes to the Disclosure Requirements for Defined Benefit Plans." The amendments in this ASU modify the disclosure requirements for employers that sponsor defined benefit plans or other postretirement plans. Disclosures removed by this ASU include the following: 1) amounts in accumulated other comprehensive income expected to be recognized in net periodic benefit costs over the next fiscal year; 2) the amount and timing of plan assets expected to be returned to the employer; and 3) the effects of a one percentage point change in assumed health care cost trend rates on the net periodic benefit costs and the benefit obligation for postretirement health care benefits. Additional disclosures required by this ASU include: 1) the weighted-average interest crediting rates used in an entity's cash balance pension plans and other similar plans and 2) explanations for reasons for significant changes in the benefit obligation or plan assets. These amendments are to be applied retrospectively. This ASU became effective on January 1, 2021 for the Corporation. The adoption of this ASU did not have a material impact on the Corporation's financial statement disclosures but will result in the elimination of certain disclosures for retirement plans and other postretirement benefits in the Form 10-K. In December 2019, the FASB issued ASU No. 2019-12, " Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes." The ASU adds new guidance to simplify accounting for income taxes, changes the accounting for certain income tax transactions and makes minor improvements to the codification. This ASU became effective on January 1, 2021 for the Corporation. The adoption of this ASU did not have a material impact on the Corporation's financial statements. Recent Accounting Pronouncements Yet to Be Adopted In January 2020, the FASB issued ASU No. 2020-01, " Investments—Equity Securities (Topic 321): Investments—Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815): Clarifying the Interactions between Topic 321, Topic 323, and Topic 815." This ASU 2020-01 clarifies the interactions between ASC 321, ASC 323 and ASC 815 and addresses accounting for the transition into and out of the equity method and measuring certain purchased options and forward contracts to acquire investments. This ASU is effective for fiscal years beginning after December 15, 2021 or January 1, 2022 for the Corporation. The Corporation does not expect the adoption of this ASU will have a material impact on the Corporation's financial statements. In March 2020, the FASB issued ASU No. 2020-04, " Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting." The guidance allows for companies to: (1) account for certain contract modifications as a continuation of the existing contract without additional analysis; (2) continue hedge accounting when certain critical terms of a hedging relationship change and assess effectiveness in ways that disregard certain potential sources of ineffectiveness; and (3) make a one-time sale and/or transfer of certain debt securities from held-to-maturity to available-for-sale or trading. This ASU is available for adoption effective immediately, or as of January 1, 2020 or any date thereafter for the Corporation, and applies prospectively to contract modifications and hedging relationships. The one-time election to sell and/or transfer debt securities classified as held-to-maturity may be made at any time after March 12, 2020. The Corporation anticipates adopting this ASU and will continue to analyze the provisions of the ASU in connection with ongoing procedures to monitor the work of the Alternative Rates Committee of the FRB and Federal Reserve Bank of New York in identifying an alternative U.S. dollar reference interest rate. It is too early to predict whether a new rate index replacement and the adoption of the ASU will have a material impact on the Corporation's financial statements. In August 2020, the FASB issued ASU No. 2020-06, "Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40) ." This guidance simplifies the accounting for convertible debt and convertible preferred stock by removing the requirements to separately present certain conversion features in equity. In addition, the amendments in the ASU also simplify the guidance in ASC 815-40 by removing certain criteria that must be satisfied in order to classify a contract as equity, which is expected to decrease the number of freestanding instruments and embedded derivatives accounted for as assets or liabilities. Finally, the amendments revise the guidance on calculating earnings per share, requiring use of the if-converted method for all convertible instruments and require entities to presume share settlement for purposes of calculating diluted EPS when an instrument may be settled in cash or shares. This ASU is effective for fiscal years beginning after December 15, 2021 or January 1, 2022 for the Corporation. The Corporation does not expect the adoption of this ASU will have a material impact on the Corporation's financial statements. In January 2021, the FASB issued ASU No. 2021-01, which refines the scope of ASU No. 2020-04, " Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting",
