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 or nine-month periods ended September 30, 2020 are not necessarily indicative of the results that may be expected for the year ended December 31, 2020 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, 2019, which was filed with the SEC on February 28, 2020. 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 calculation of the allowance for credit losses. Accounting Pronouncements Adopted in 2020 In June 2016, the FASB issued ASU No. 2016-13, “ Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments” and subsequent related updates. This ASU replaces the incurred loss methodology for recognizing credit losses and requires businesses and other organizations to measure the current expected credit losses (CECL) on financial assets measured at amortized cost, including loans and held-to-maturity securities, net investments in leases accounted for under ASC 842, off-balance sheet credit exposures such as unfunded commitments, and other financial instruments. In addition, ASC 326 requires credit losses on available-for-sale debt securities to be presented as an allowance rather than as a write-down when management does not intend to sell or believes that it is not more likely than not they will be required to sell. This guidance became effective on January 1, 2020 for the Corporation. The results reported for periods beginning after January 1, 2020 are presented under ASC 326 while prior period amounts continue to be reported in accordance with previously applicable accounting standards. See Note 1, "Summary of Significant Accounting Polices - Reserve for Loan and Lease Losses" in the Annual Report on Form 10-K for the year ended December 31, 2019, which was filed with the SEC on February 28, 2020, for further information on the Corporation's reserve for loan and lease losses methodology under the incurred loss model. The Corporation adopted this guidance, and subsequent related updates, using the modified retrospective approach for all financial assets measured at amortized cost, including loans and held-to-maturity securities, net investments in leases, available-for-sale debt securities and unfunded commitments. On January 1, 2020, the Corporation recorded a cumulative effect decrease to retained earnings of $11.3 million, net of tax, of which $10.2 million related to loans and net investment in leases, $905 thousand related to unfunded commitments, and $237 thousand related to available-for-sale securities. The Corporation adopted the provisions of ASC 326 related to financial assets purchased with credit deterioration (PCD) that were previously classified as purchased credit impaired (PCI) and accounted for under ASC 310-30 using the prospective transition approach. In accordance with the standard, management did not reassess whether PCI assets met the criteria of PCD assets as of the date of adoption. On January 1, 2020, the amortized cost basis of the PCD assets were adjusted to reflect the addition of $84 thousand of the allowance for credit losses (ACL). The Corporation adopted the provisions of ASC 326 related to presenting other-than-temporary impairment on available-for-sale debt securities prior to January 1, 2020 using the prospective transition approach, though no such charges had been recorded on the securities held by the Corporation as of the date of adoption. In April 2019, the FASB issued ASU No. 2019-04, "Codification Improvements to Financial Instruments-Credit Losses (Topic 326), Derivatives and Hedging (Topic 815) and Financial Instruments (Topic 825)." The amendments to Topic 326 are the most significant and address how a company considers recoveries and extension options when estimating expected credit losses. The ASU clarifies that a company’s estimate of expected credit losses should include expected recoveries of financial assets, including recoveries of amounts expected to be written off and those previously written off. The ASU also clarifies that a company should consider contractual extension or renewal options that it cannot unconditionally cancel when determining the contractual term over which expected credit losses are measured. This new guidance was effective on January 1, 2020 for the Corporation. The Corporation adopted ASU No. 2019-04 and incorporated the applicable items into the CECL model described as follows. Management addressed the provision in ASU No. 2019-04 related to how a company considers recoveries by performing an analysis to estimate recoveries that could be reasonably expected based on historical experience as described further below. Management addressed the provision in ASU No. 2019-04 related to how a company considers extension options when estimating expected credit losses as described further below. Management reviewed the provision in the ASU No. 2019-04 related to Topics 815 and 825 and determined these amendments did not have a material impact on the Corporation's financial statements. The Corporation expanded the pooling utilized under the legacy incurred loss method to include additional segmentation based on risk. The impact of the change from the incurred loss model to the current expected credit loss model is detailed below. January 1, 2020 (Dollars in thousands) Pre-adoption Adoption Impact As Reported Assets: ACL on debt securities: available-for-sale: Corporate bonds $ — $ 300 $ 300 ACL on loans and leases: Commercial, financial and agricultural 8,759 5,284 14,043 Real estate-commercial 15,750 6,208 21,958 Real estate-construction 2,446 29 2,475 Real estate-residential secured for business purpose 2,622 2,502 5,124 Real estate-residential secured for personal purpose 2,713 (706) 2,007 Real estate-home equity secured for personal purpose 1,076 (364) 712 Loans to individuals 470 104 574 Lease financings 1,311 (135) 1,176 Unallocated 184 — 184 Total ACL on loans and leases 35,331 12,922 48,253 Liabilities: Reserve for unfunded commitments $ 420 $ 1,145 $ 1,565 In August 2018, the FASB issued ASU No. 2018-13, " Fair Value Measurement (Topic 820): Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement." This ASU applies to all entities that are required, under existing GAAP, to make disclosures about recurring or nonrecurring fair value measurements. Disclosures removed by this ASU are the amount and reasons for transfers between Level 1 and Level 2, the policy for timing of transfers between levels and the valuation processes for Level 3 measurements. This ASU modifies certain disclosures relating to investments in certain entities that calculate net asset value, changes in unrealized gains and losses included in other comprehensive income for recurring Level 3 fair value measurements held at the end of the reporting period and range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. The Corporation adopted this guidance and the related required disclosures prospectively on January 1, 2020. In January 2017, the FASB issued ASU No. 2017-04, "Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment." This ASU eliminates Step 2 of the goodwill impairment test. Step 2 measures a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of that goodwill. Under the new guidance, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. Additionally, an entity should consider income tax effects from any tax-deductible goodwill on the carrying amount of the reporting unit when measuring the goodwill impairment loss, if applicable. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. Public business entities that are SEC filers should adopt the amendments in this ASU for annual or interim goodwill impairment tests in fiscal years beginning after December 15, 2019, or for the Corporation's goodwill impairment test in 2020. The Corporation adopted this guidance as of January 1, 2020. The adoption did not have a material impact on the Corporation's financial statements. Recent Accounting Pronouncements Yet to Be Adopted 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. All amendments should be applied retrospectively. This ASU is effective for fiscal years beginning after December 15, 2020 or January 1, 2021 for the Corporation. The Corporation does not expect the adoption of this ASU will have a material impact on the Corporation's financial statement disclosures but will result in revised disclosures for retirement plans and other postretirement benefits. 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 is effective for fiscal years beginning after December 15, 2020 or January 1, 2021 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 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, which we anticipate will be the Secured Overnight Financing Rate (SOFR), 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. Investment Securities Securities are classified as investment securities held-to-maturity and carried at amortized cost if management has the positive intent and ability to hold the securities to maturity. Securities purchased with the intention of recognizing short-term profits are placed in the trading account and are carried at fair value. Securities classified as available-for-sale are those securities that the Corporation intends to hold for an indefinite period of time but not necessarily to maturity. Securities available-for-sale are carried at fair value with unrealized gains and losses, net of estimated income taxes, reflected in accumulated other comprehensive income, a separate component of shareholders' equity, and credit losses are recognized in earnings. Any decision to sell a security classified as available-for-sale would be based on various factors, including interest rates, changes in the maturity or mix of the Corporation's assets and liabilities, liquidity needs, regulatory capital considerations and other factors. Management determines the appropriate classification of debt securities at the time of purchase and re-evaluates such designation as of each balance sheet date. Purchase premiums and discounts are recognized in interest income using the interest method over the expected life of the securities except for premiums on callable debt securities which are amortized to the earliest call date. Due to volatility in the financial markets, there is the risk that any future fair value could vary from that disclosed in the accompanying financial statements. Realized gains and losses on the sale of investment securities are recorded on the trade date, determined using the specific identification method and are included in the consolidated statements of income. The Corporation measures expected credit losses on held-to-maturity debt securities, which are comprised of U.S. government agency securities and residential mortgage-backed securities. The Corporation's residential mortgage-backed security holdings are issued by 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. Accrued interest receivable on held-to-maturity debt securities totaled $474 thousand at September 30, 2020 and is included within Accrued interest receivable and other assets. This amount is excluded from the estimate of expected credit losses. Held-to-maturity debt securities are typically classified as nonaccrual when the contractual payment of principal or interest has become 90 days past due or management has serious doubts about the further collectability of principal or interest. When held-to-maturity debt securities are placed on nonaccrual status, unpaid interest credited to income is reversed. The Corporation measures expected credit losses on available-for-sale debt securities when the Corporation does not intend to sell, or when it is not more likely than not that it will be required to sell the security before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the security's amortized cost basis is written down to fair value through income. For available-for-sale debt securities that do not meet the aforementioned criteria, the Corporation evaluates whether the decline in fair value has resulted from credit losses or other factors. In making this assessment, the Corporation considers the extent to which fair value is less than amortized cost, any changes to the rating of the security by a rating agency, and adverse conditions specifically related to the security, among other factors. If this evaluation indicates that a credit loss exists, the present value of cash flows expected to be collected from the security are compared to the amortized cost basis of the security. If the present value of cash flows expected to be collected is less than the amortized cost basis, a credit loss exists and an allowance for credit losses is recorded for the credit loss, equal to the amount that the fair value is less than the amortized cost basis. Economic forecast data is utilized to calculate the present value of expected cash flows. The forecast data is obtained via a subscription to a widely recognized and relied upon company who publishes various forecast scenarios. Management evaluates the various scenarios to determine a reasonable and supportable scenario. Any impairment that has not been recorded through an allowance for credit losses is recognized in other comprehensive income. The allowance for credit losses on available-for-sale debt securities is included within Investment securities available-for-sale on the condensed consolidated balance sheet. Changes in the allowance for credit losses are recorded within Provision for credit losses on the condensed consolidated statement of income. Losses are charged against the allowance when the Corporation believes the collectability of an available-for-sale security is in jeopardy or when either of the criteria regarding intent or requirement to sell is met. Accrued interest receivable on available-for-sale debt securities totaled $547 thousand at September 30, 2020 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. Available-for-sale debt securities are typically classified as nonaccrual when the contractual payment of principal or interest has become 90 days past due or management has serious doubts about the further collectability of principal or interest. When available-for-sale debt securities are placed on nonaccrual status, unpaid interest credited to income is reversed. Equity securities are measured at fair value with changes in fair value recognized in net income. Loans and Leases Loans that the Corporation has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at amortized cost, which is the principal amount, net of deferred fees and costs, and the allowance for credit losses. Lease financings are stated at net investment amount, consisting of the present value of lease payments and unguaranteed residual value, plus initial direct costs. Loan commitments are made to accommodate the financial needs of customers. These commitments represent off-balance sheet items that are unfunded. The Corporation uses the same credit policies in making commitments and conditional obligations as it does for on-balance sheet financial instruments. Accrual of interest income on loans and leases ceases when collectability of interest and/or principal is questionable. If it is determined that the collection of interest previously accrued is uncertain, such accrual is reversed and charged to current earnings. Loans and leases are considered past due based upon the failure to comply with contractual terms. A loan or lease is typically classified as nonaccrual when the contractual payment of principal or interest has become 90 days past due or management has serious doubts about the further collectability of principal or interest, even though the loan or lease is currently performing. When a loan or lease is classified as nonaccrual, the accrual of interest on such a loan or lease is discontinued. A loan or lease may remain on accrual status if it is in the process of collection and is either guaranteed or well secured. When a loan or lease is placed on nonaccrual status, unpaid interest credited to income is reversed and the amortization of the deferred fees and costs is suspended. Interest payments received on nonaccrual loans and leases are either applied against principal or reported as interest income, according to management’s judgment as to the ultimate collectability of principal. Loans and leases are usually restored to accrual status when the obligation is brought current, has performed in accordance with the contractual terms for a reasonable period of time, and the ultimate collectability of the total contractual principal and interest is no longer in doubt. A loan or lease is classified as a troubled debt restructuring when a concession has been granted to an existing borrower experiencing financial difficulties. The Corporation grants concessions to existing borrowers primarily related to extensions of interest-only payment periods and an occasional payment modification. These modifications typically are for up to one year. The goal when restructuring a credit is to establish a reasonable period of time to provide cash flow relief to customers experiencing cash flow difficulties. Accruing troubled debt restructured loans are primarily comprised of loans on which interest is being accrued under the restructured terms, and the loans are current or less than 90 days past due. Certain loan modifications made during the year were done in accordance with Section 4013 of the CARES Act and the Interagency Statement on Loan Modifications and Reporting for Financial Institutions Working with Customers Affected by the Coronavirus . Accordingly, these loans and leases were not categorized as troubled debt restructurings. Accrued interest receivable on loans and leases held for investment totaled $14.9 million at September 30, 2020 and is included within Accrued interest receivable and other assets on the condensed consolidated balance sheet. $12.3 million of this amount is excluded from the estimate of expected credit losses. $2.6 million of this amount represents accrued interest receivable on loans that were modified in accordance with Section 4013 of the CARES Act and the Interagency Statement on Loan Modifications and Reporting for Financial Institutions Working with Customers Affected by the Coronavirus and includes an allowance for credit losses of $50 thousand. Overdraft deposits are re-classified as loans and are included in the total loans and leases on the balance sheet. Loan and Lease Fees Fees collected upon loan or lease origination and certain direct costs of originating loans and leases are deferred and recognized over the contractual lives of the related loans and leases as yield adjustments using the interest method. Upon prepayment or other disposition of the underlying loans and leases before their contractual maturities, any associated unearned fees or unamortized costs are recognized. Initial direct costs, comprised of commissions paid that would not have been incurred if the lease had not been obtained, are deferred and amortized over the life of the contract, and are classified within net interest income on leases. Allowance for Credit Losses on Loans and Leases The allowance for credit losses (ACL) on loans and leases is a valuation account that is used to present the net amount expected to be collected on a loan or lease. The ACL for loans and leases is adjusted through provision for credit losses as a charge against, or credit to, earnings. Loans and leases deemed to be uncollectible are charged against the ACL on loans and leases, and any subsequent recoveries are credited to the ACL. Management evaluates the ACL on a quarterly basis. When changes in the reserve are necessary, an adjustment is made. Management utilizes a discounted cash flow (DCF) model to calculate the present value of the expected cash flows for pools of loans and leases that share similar risk characteristics and compares the results of this calculation to the amortized cost basis to determine its allowance for credit loss balance. Management uses relevant available information, from internal and external sources, relating to past events, current conditions, and reasonable and supportable forecasts in calculating its ACL. Historical credit loss experience provides the basis for the estimation of expected credit losses. Management determines whether there is a need to make qualitative adjustments to historical loss information by monitoring certain factors including differences in current loan-specific risk characteristics as well as for changes in external or environmental conditions, or other relevant factors. The contractual term used in projecting the cash flows of a loan is based on the maturity date of a loan, and is adjusted for prepayment or curtailment assumptions which may shorten that contractual time period. Options to extend are considered by management in determining the contractual term. The key inputs to the DCF model are (1) probability of default, (2) loss given default, (3) prepayment and curtailment rates, (4) reasonable and supportable economic forecasts, (5) forecast reversion period, (6) expected recoveries on charged off loans, and (7) discount rate. Probability of Default (PD) In order to incorporate economic factors into forecasting within the DCF model, management elected to use the Loss Driver method to generate the PD rate inputs. The Loss Driver method analyzes how one or more economic factors change the default rate using a statistical regression analysis. Management selected economic factors that had strong correlations to historical default rates. Loss Given Default (LGD) Management elected to use the Frye Jacobs parameter for determining the LGD input, which is an estimation technique that derives a LGD input from segment specific risk curves that correlates LGD with PD. Prepayment and Curtailment rates Prepayment Rates: Loan level transaction data is used to calculate a quarterly prepayment rate for each of the most recent four quarters prior to the measurement date. Those quarterly rates are annualized and the average of the annualized rates is used in the DCF calculation for fixed payment or term loans. Rates are calculated for each pool. Curtailment Rates: Loan level transaction data is used to calculate annual curtailment rates using any available historical loan level data. The average of the historical rates is used in the DCF model for interest only payment or line of credit type loans. Rates are calculated for each pool. Reasonable and Supportable Forecasts The forecast data used in the DCF model is obtained via a subscription to a widely recognized and relied upon company who publishes various forecast scenarios. Management evaluates the various scenarios to determine a reasonable and supportable scenario. Forecast Reversion Period Management uses forecasts to predict how economic factors will perform and has determined to use a four quarter forecast period as well as a four quarter straight-line reversion period to historical averages (also commonly referred to as the mean reversion period). Expected Recoveries on Charged-off Loans Management performs an analysis to estimate recoveries that could be reasonably expected based on historical experience in order to account for expected recoveries on loans that have already been fully charged-off and are not included in the ACL calculation. Discount Rate The effective interest rate of the underlying loans and leases of the Corporation serves as the discount rate applied to the expected periodic cash flows. Management adjusts the effective interest rate used to discount expected cash flows to incorporate expected prepayments. Individual Evaluation Management evaluates individual instruments for expected credit losses when those instruments do not share similar risk characteristics with instruments evaluated using a collective (pooled) basis. Management individually analyzes these instruments and will establish a specific reserve for instruments as applicable. Instruments will not be included in both collective and individual analyses. All loans on nonaccrual status are individually evaluated for a specific reserve. Management considers a financial asset as collateral-dependent when the debtor is experiencing financial difficulty and repayment is expected to be provided substantially through the sale or operation of the collateral, based on management's assessment as of the reporting date. The allowance for credit losses on loans and leases is included within Allowance for credit losses, loans and leases on the condensed consolidated balance sheet. Changes in the allowance for credit losses on loans and leases are recorded within Provision for credit losses on the condensed consolidated statement of income. Reserve for Unfunded Commitments The Corporation maintains a reserve for off-balance sheet credit exposures such as unfunded commitments that are currently unfunded in categories with historical loss experience. Management calculates funding rates using loan level data history at the portfo

Expected maturities may differ from contractual maturities because debt issuers may have the right to call or prepay obligations without call or prepayment penalties and mortgage-backed securities typically prepay at a rate faster than contractually due. Securities with a carrying value of $289.6 million and $340.8 million at September 30, 2020 and December 31, 2019, respectively, were pledged to secure public funds deposits and other contractual obligations. In addition, securities of $38.9 million and $12.5 million were pledged to secure credit derivatives and interest rate swaps at September 30, 2020 and December 31, 2019, respectively. See Note 11, "Derivative Instruments and Hedging Activities" for additional information.

These holdings were comprised of four 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. The Corporation did not recognize any other-than-temporary impairment charges for the nine months ended September 30, 2019. At September 30, 2020, no held-to-maturity securities held by the Corporation were in an unrealized loss position. The Corporation did not recognize any credit losses on held-to-maturity debt securities for the nine months ended September 30, 2020 or other-than-temporary impairment charges for the nine months ended September 30, 2019. The table below presents a rollforward by major security type for the three and nine months ended September 30, 2020 of the allowance for credit losses on securities available-for-sale.

These holdings were comprised of eight investment grade corporate bonds which fluctuate in value based on changes in market conditions, which for these underlying securities was 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 interest payments on the securities. The Corporation concluded that a portion of decline in the value of these securities was indicative of a credit loss and recorded a provision for credit losses of $392 thousand for the nine months ended September 30, 2020. The Corporation did not record any other-than-temporary impairment charges for the nine months ended September 30, 2019. The Corporation recognized a $321 thousand net loss and $12 thousand net gain on equity securities during the nine months ended September 30, 2020 and 2019, respectively, in other noninterest income. There were no sales of equity securities during the nine months ended September 30, 2020 or September 30, 2019.

The following is a description of the internal risk ratings and the likelihood of loss related to each risk rating. Loans with a relationship balance of less than $1 million are reviewed on a performance basis, with the primary monitored metrics being delinquency status. 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, 2019. 1. Pass—Loans considered satisfactory with no indications of deterioration 2. Special Mention—Potential weakness that deserves management's close attention 3.

Retirement Plans and Other Postretirement Benefits	Retirement Plans and Other Postretirement Benefits Substantially all employees who were hired before December 8, 2009 are covered by a non-contributory retirement plan. Employees hired on or after December 8, 2009 are not eligible to participate in the non-contributory retirement plan. The Corporation also maintains a non-qualified benefit plan that provides supplemental executive retirement benefits to certain former executives, a portion of which is in excess of limits imposed on qualified plans by federal tax law. This non-qualified benefit plan is not offered to new participants and all current participants are now retired. Information on these plans are aggregated and reported under “Retirement Plans” within this footnote. The Corporation also provides certain postretirement healthcare and life insurance benefits for retired employees. Information on these benefits is reported under “Other Postretirement Benefits” within this footnote.

Share-based Payment Arrangement [Abstract]
Share-Based Incentive Plan	Stock-Based Incentive Plan The Corporation has a shareholder approved 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 nine months ended September 30, 2020: (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 September 30, 2020 Outstanding at December 31, 2019 508,111 $ 24.83 Expired (2,000) 28.33 Forfeited (19,018) 24.70 Exercised (5,000) 18.70 Outstanding at September 30, 2020 482,093 24.88 5.9 $ — Exercisable at September 30, 2020 428,615 24.43 5.7 — The following is a summary of nonvested stock options at September 30, 2020 including changes during the nine 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, 2019 163,261 $ 6.54 Vested (106,131) 6.58 Forfeited (3,652) 6.50 Nonvested stock options at September 30, 2020 53,478 6.46 The Corporation did not issue stock options during the nine months ended September 30, 2020 or September 30, 2019.

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 September 30, 2020, approximately $235 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 September 30, 2020. At September 30, 2020, the notional amount of the interest rate swap was $15.7 million and the fair value was a liability of $614 thousand. The Corporation has an interest rate swap with a current notional amount of $211 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 September 30, 2020, the Corporation reported seventy-seven variable-rate to fixed-rate interest rate swap transactions between the third-party financial institution and customers with a current notional amount of $552.2 million and remaining maturities ranging from 18 months to 10 years. At September 30, 2020, the fair value of the Corporation's interest rate swap credit derivatives was a liability of $716 thousand. At September 30, 2020, the fair value of the swaps to the customers was a net liability of $36.9 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 September 30, 2020 and December 31, 2019. The Corporation pledges cash or securities to cover the negative fair value of derivative instruments.

Fair Value Disclosures

Fair Value Disclosures	9 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. Transfers between levels were recognized at the end of the reporting period for the year ended December 31, 2019. 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 September 30, 2020. 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 September 30, 2020 since lending credit risk is not an observable input for this loan. The unrealized gain on the one loan was $9 thousand at September 30, 2020. 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 September 30, 2020 and December 31, 2019, classified using the fair value hierarchy: At September 30, 2020 (Dollars in thousands) Level 1 Level 2 Level 3 Assets/ Assets: Available-for-sale securities: State and political subdivisions $ — $ 15,187 $ — $ 15,187 Residential mortgage-backed securities — 81,671 — 81,671 Collateralized mortgage obligations — 5,830 — 5,830 Corporate bonds — 86,539 — 86,539 Total available-for-sale securities — 189,227 — 189,227 Equity securities: Equity securities - financial services industry 683 — — 683 Money market mutual funds 2,103 — — 2,103 Total equity securities 2,786 — — 2,786 Loans* — — 221 221 Interest rate locks with customers* — 4,896 — 4,896 Total assets $ 2,786 $ 194,123 $ 221 $ 197,130 Liabilities: Contingent consideration liability $ — $ — $ 83 $ 83 Interest rate swaps* — 624 — 624 Credit derivatives* — — 716 716 Forward loan sale commitments* — 474 — 474 Total liabilities $ — $ 1,098 $ 799 $ 1,897 * Such financial instruments are recorded at fair value as further described in Note 11, "Derivative Instruments and Hedging Activities." The Corporation recorded no unrealized gains and losses within other comprehensive income for recurring Level 3 fair value measurements held at September 30, 2020. The $716 thousand of credit derivatives liability represents the Credit Valuation Adjustment (CVA), which is obtained from real-time financial market data, of seventy-seven interest rate swaps with a current notional amount of $552.2 million. The September 30, 2020 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 September 30, 2020, individually analyzed loans held for investment had a carrying amount of $29.8 million with a valuation allowance of $1.1 million. At December 31, 2019, impaired loans held for investment had a carrying amount of $38.1 million with a valuation allowance of $2.1 million. The Corporation had no individually analyzed leases at September 30, 2020. The Corporation had impaired leases of $277 thousand with no reserve at December 31, 2019. 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 September 30, 2020, servicing rights had a net carrying amount of $6.3 million which included a valuation allowance of $206 thousand. At December 31, 2019, servicing rights carrying amount of $6.6 million with no valuation allowance. 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 nine months ended September 30, 2020, there were no required valuation adjustments of goodwill and other identifiable intangible assets. Other real estate owned: The fair value of other real estate owned (OREO) is originally estimated based upon the appraised value less estimated costs to sell. The fair value less cost to sell becomes the "original cost" of the OREO asset. Subsequently, OREO is reported at the lower of the original cost or the current fair value less cost to sell. Capital improvement expenses associated with the construction or repair of the property are capitalized as part of the cost of the OREO asset; however, the capitalized expenses may not increase the OREO asset's recorded value to an amount greater than the asset's fair value after improvements and less cost to sell. New appraisals are generally obtained on an annual basis if an agreement of sale does not exist. During the nine months ended September 30, 2020, one property was transferred to OREO with a carrying balance of $8.1 million, one property had a write-down totaling $300 thousand, and one property sold with total proceeds of $75 thousand for a net gain of $4 thousand. At September 30, 2020 and December 31, 2019, OREO had a carrying amount of $8.3 million and $540 thousand, 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 September 30, 2020, 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 below. ● 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 trust and investment advisory services, guardian and custodian of employee benefits and other trust and brokerage services, as well as a registered investment advisory managing private investment accounts for both individuals and institutions. ● The Insurance segment includes a full-service insurance brokerage agency offering commercial property and casualty insurance, group life and health coverage, 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.

Accounting Policies [Abstract]
Principles of Consolidation and Basis of Presentation	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 or nine-month periods ended September 30, 2020 are not necessarily indicative of the results that may be expected for the year ended December 31, 2020 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, 2019, which was filed with the SEC on February 28, 2020.
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 calculation of the allowance for credit losses.
Recent Accounting Pronouncements	Accounting Pronouncements Adopted in 2020 In June 2016, the FASB issued ASU No. 2016-13, “ Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments” and subsequent related updates. This ASU replaces the incurred loss methodology for recognizing credit losses and requires businesses and other organizations to measure the current expected credit losses (CECL) on financial assets measured at amortized cost, including loans and held-to-maturity securities, net investments in leases accounted for under ASC 842, off-balance sheet credit exposures such as unfunded commitments, and other financial instruments. In addition, ASC 326 requires credit losses on available-for-sale debt securities to be presented as an allowance rather than as a write-down when management does not intend to sell or believes that it is not more likely than not they will be required to sell. This guidance became effective on January 1, 2020 for the Corporation. The results reported for periods beginning after January 1, 2020 are presented under ASC 326 while prior period amounts continue to be reported in accordance with previously applicable accounting standards. See Note 1, "Summary of Significant Accounting Polices - Reserve for Loan and Lease Losses" in the Annual Report on Form 10-K for the year ended December 31, 2019, which was filed with the SEC on February 28, 2020, for further information on the Corporation's reserve for loan and lease losses methodology under the incurred loss model. The Corporation adopted this guidance, and subsequent related updates, using the modified retrospective approach for all financial assets measured at amortized cost, including loans and held-to-maturity securities, net investments in leases, available-for-sale debt securities and unfunded commitments. On January 1, 2020, the Corporation recorded a cumulative effect decrease to retained earnings of $11.3 million, net of tax, of which $10.2 million related to loans and net investment in leases, $905 thousand related to unfunded commitments, and $237 thousand related to available-for-sale securities. The Corporation adopted the provisions of ASC 326 related to financial assets purchased with credit deterioration (PCD) that were previously classified as purchased credit impaired (PCI) and accounted for under ASC 310-30 using the prospective transition approach. In accordance with the standard, management did not reassess whether PCI assets met the criteria of PCD assets as of the date of adoption. On January 1, 2020, the amortized cost basis of the PCD assets were adjusted to reflect the addition of $84 thousand of the allowance for credit losses (ACL). The Corporation adopted the provisions of ASC 326 related to presenting other-than-temporary impairment on available-for-sale debt securities prior to January 1, 2020 using the prospective transition approach, though no such charges had been recorded on the securities held by the Corporation as of the date of adoption. In April 2019, the FASB issued ASU No. 2019-04, "Codification Improvements to Financial Instruments-Credit Losses (Topic 326), Derivatives and Hedging (Topic 815) and Financial Instruments (Topic 825)." The amendments to Topic 326 are the most significant and address how a company considers recoveries and extension options when estimating expected credit losses. The ASU clarifies that a company’s estimate of expected credit losses should include expected recoveries of financial assets, including recoveries of amounts expected to be written off and those previously written off. The ASU also clarifies that a company should consider contractual extension or renewal options that it cannot unconditionally cancel when determining the contractual term over which expected credit losses are measured. This new guidance was effective on January 1, 2020 for the Corporation. The Corporation adopted ASU No. 2019-04 and incorporated the applicable items into the CECL model described as follows. Management addressed the provision in ASU No. 2019-04 related to how a company considers recoveries by performing an analysis to estimate recoveries that could be reasonably expected based on historical experience as described further below. Management addressed the provision in ASU No. 2019-04 related to how a company considers extension options when estimating expected credit losses as described further below. Management reviewed the provision in the ASU No. 2019-04 related to Topics 815 and 825 and determined these amendments did not have a material impact on the Corporation's financial statements. The Corporation expanded the pooling utilized under the legacy incurred loss method to include additional segmentation based on risk. The impact of the change from the incurred loss model to the current expected credit loss model is detailed below. January 1, 2020 (Dollars in thousands) Pre-adoption Adoption Impact As Reported Assets: ACL on debt securities: available-for-sale: Corporate bonds $ — $ 300 $ 300 ACL on loans and leases: Commercial, financial and agricultural 8,759 5,284 14,043 Real estate-commercial 15,750 6,208 21,958 Real estate-construction 2,446 29 2,475 Real estate-residential secured for business purpose 2,622 2,502 5,124 Real estate-residential secured for personal purpose 2,713 (706) 2,007 Real estate-home equity secured for personal purpose 1,076 (364) 712 Loans to individuals 470 104 574 Lease financings 1,311 (135) 1,176 Unallocated 184 — 184 Total ACL on loans and leases 35,331 12,922 48,253 Liabilities: Reserve for unfunded commitments $ 420 $ 1,145 $ 1,565 In August 2018, the FASB issued ASU No. 2018-13, " Fair Value Measurement (Topic 820): Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement." This ASU applies to all entities that are required, under existing GAAP, to make disclosures about recurring or nonrecurring fair value measurements. Disclosures removed by this ASU are the amount and reasons for transfers between Level 1 and Level 2, the policy for timing of transfers between levels and the valuation processes for Level 3 measurements. This ASU modifies certain disclosures relating to investments in certain entities that calculate net asset value, changes in unrealized gains and losses included in other comprehensive income for recurring Level 3 fair value measurements held at the end of the reporting period and range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. The Corporation adopted this guidance and the related required disclosures prospectively on January 1, 2020. In January 2017, the FASB issued ASU No. 2017-04, "Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment." This ASU eliminates Step 2 of the goodwill impairment test. Step 2 measures a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of that goodwill. Under the new guidance, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. Additionally, an entity should consider income tax effects from any tax-deductible goodwill on the carrying amount of the reporting unit when measuring the goodwill impairment loss, if applicable. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. Public business entities that are SEC filers should adopt the amendments in this ASU for annual or interim goodwill impairment tests in fiscal years beginning after December 15, 2019, or for the Corporation's goodwill impairment test in 2020. The Corporation adopted this guidance as of January 1, 2020. The adoption did not have a material impact on the Corporation's financial statements. Recent Accounting Pronouncements Yet to Be Adopted 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. All amendments should be applied retrospectively. This ASU is effective for fiscal years beginning after December 15, 2020 or January 1, 2021 for the Corporation. The Corporation does not expect the adoption of this ASU will have a material impact on the Corporation's financial statement disclosures but will result in revised disclosures for retirement plans and other postretirement benefits. 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 is effective for fiscal years beginning after December 15, 2020 or January 1, 2021 for the Corporation.

Investment Securities	Investment Securities Securities are classified as investment securities held-to-maturity and carried at amortized cost if management has the positive intent and ability to hold the securities to maturity. Securities purchased with the intention of recognizing short-term profits are placed in the trading account and are carried at fair value. Securities classified as available-for-sale are those securities that the Corporation intends to hold for an indefinite period of time but not necessarily to maturity. Securities available-for-sale are carried at fair value with unrealized gains and losses, net of estimated income taxes, reflected in accumulated other comprehensive income, a separate component of shareholders' equity, and credit losses are recognized in earnings. Any decision to sell a security classified as available-for-sale would be based on various factors, including interest rates, changes in the maturity or mix of the Corporation's assets and liabilities, liquidity needs, regulatory capital considerations and other factors. Management determines the appropriate classification of debt securities at the time of purchase and re-evaluates such designation as of each balance sheet date. Purchase premiums and discounts are recognized in interest income using the interest method over the expected life of the securities except for premiums on callable debt securities which are amortized to the earliest call date. Due to volatility in the financial markets, there is the risk that any future fair value could vary from that disclosed in the accompanying financial statements. Realized gains and losses on the sale of investment securities are recorded on the trade date, determined using the specific identification method and are included in the consolidated statements of income. The Corporation measures expected credit losses on held-to-maturity debt securities, which are comprised of U.S. government agency securities and residential mortgage-backed securities. The Corporation's residential mortgage-backed security holdings are issued by 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. Accrued interest receivable on held-to-maturity debt securities totaled $474 thousand at September 30, 2020 and is included within Accrued interest receivable and other assets. This amount is excluded from the estimate of expected credit losses. Held-to-maturity debt securities are typically classified as nonaccrual when the contractual payment of principal or interest has become 90 days past due or management has serious doubts about the further collectability of principal or interest. When held-to-maturity debt securities are placed on nonaccrual status, unpaid interest credited to income is reversed. The Corporation measures expected credit losses on available-for-sale debt securities when the Corporation does not intend to sell, or when it is not more likely than not that it will be required to sell the security before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the security's amortized cost basis is written down to fair value through income. For available-for-sale debt securities that do not meet the aforementioned criteria, the Corporation evaluates whether the decline in fair value has resulted from credit losses or other factors. In making this assessment, the Corporation considers the extent to which fair value is less than amortized cost, any changes to the rating of the security by a rating agency, and adverse conditions specifically related to the security, among other factors. If this evaluation indicates that a credit loss exists, the present value of cash flows expected to be collected from the security are compared to the amortized cost basis of the security. If the present value of cash flows expected to be collected is less than the amortized cost basis, a credit loss exists and an allowance for credit losses is recorded for the credit loss, equal to the amount that the fair value is less than the amortized cost basis. Economic forecast data is utilized to calculate the present value of expected cash flows. The forecast data is obtained via a subscription to a widely recognized and relied upon company who publishes various forecast scenarios. Management evaluates the various scenarios to determine a reasonable and supportable scenario. Any impairment that has not been recorded through an allowance for credit losses is recognized in other comprehensive income. The allowance for credit losses on available-for-sale debt securities is included within Investment securities available-for-sale on the condensed consolidated balance sheet. Changes in the allowance for credit losses are recorded within Provision for credit losses on the condensed consolidated statement of income. Losses are charged against the allowance when the Corporation believes the collectability of an available-for-sale security is in jeopardy or when either of the criteria regarding intent or requirement to sell is met. Accrued interest receivable on available-for-sale debt securities totaled $547 thousand at September 30, 2020 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. Available-for-sale debt securities are typically classified as nonaccrual when the contractual payment of principal or interest has become 90 days past due or management has serious doubts about the further collectability of principal or interest. When available-for-sale debt securities are placed on nonaccrual status, unpaid interest credited to income is reversed.
Loans and Leases	Loans and Leases Loans that the Corporation has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at amortized cost, which is the principal amount, net of deferred fees and costs, and the allowance for credit losses. Lease financings are stated at net investment amount, consisting of the present value of lease payments and unguaranteed residual value, plus initial direct costs. Loan commitments are made to accommodate the financial needs of customers. These commitments represent off-balance sheet items that are unfunded. The Corporation uses the same credit policies in making commitments and conditional obligations as it does for on-balance sheet financial instruments. Accrual of interest income on loans and leases ceases when collectability of interest and/or principal is questionable. If it is determined that the collection of interest previously accrued is uncertain, such accrual is reversed and charged to current earnings. Loans and leases are considered past due based upon the failure to comply with contractual terms. A loan or lease is typically classified as nonaccrual when the contractual payment of principal or interest has become 90 days past due or management has serious doubts about the further collectability of principal or interest, even though the loan or lease is currently performing. When a loan or lease is classified as nonaccrual, the accrual of interest on such a loan or lease is discontinued. A loan or lease may remain on accrual status if it is in the process of collection and is either guaranteed or well secured. When a loan or lease is placed on nonaccrual status, unpaid interest credited to income is reversed and the amortization of the deferred fees and costs is suspended. Interest payments received on nonaccrual loans and leases are either applied against principal or reported as interest income, according to management’s judgment as to the ultimate collectability of principal. Loans and leases are usually restored to accrual status when the obligation is brought current, has performed in accordance with the contractual terms for a reasonable period of time, and the ultimate collectability of the total contractual principal and interest is no longer in doubt. A loan or lease is classified as a troubled debt restructuring when a concession has been granted to an existing borrower experiencing financial difficulties. The Corporation grants concessions to existing borrowers primarily related to extensions of interest-only payment periods and an occasional payment modification. These modifications typically are for up to one year. The goal when restructuring a credit is to establish a reasonable period of time to provide cash flow relief to customers experiencing cash flow difficulties. Accruing troubled debt restructured loans are primarily comprised of loans on which interest is being accrued under the restructured terms, and the loans are current or less than 90 days past due. Certain loan modifications made during the year were done in accordance with Section 4013 of the CARES Act and the Interagency Statement on Loan Modifications and Reporting for Financial Institutions Working with Customers Affected by the Coronavirus . Accordingly, these loans and leases were not categorized as troubled debt restructurings. Accrued interest receivable on loans and leases held for investment totaled $14.9 million at September 30, 2020 and is included within Accrued interest receivable and other assets on the condensed consolidated balance sheet. $12.3 million of this amount is excluded from the estimate of expected credit losses. $2.6 million of this amount represents accrued interest receivable on loans that were modified in accordance with Section 4013 of the CARES Act and the Interagency Statement on Loan Modifications and Reporting for Financial Institutions Working with Customers Affected by the Coronavirus and includes an allowance for credit losses of $50 thousand.
Loan and Lease Fees	Loan and Lease FeesFees collected upon loan or lease origination and certain direct costs of originating loans and leases are deferred and recognized over the contractual lives of the related loans and leases as yield adjustments using the interest method. Upon prepayment or other disposition of the underlying loans and leases before their contractual maturities, any associated unearned fees or unamortized costs are recognized. Initial direct costs, comprised of commissions paid that would not have been incurred if the lease had not been obtained, are deferred and amortized over the life of the contract, and are classified within net interest income on leases.
Allowance for Credit Losses on Loans and Leases	Allowance for Credit Losses on Loans and Leases The allowance for credit losses (ACL) on loans and leases is a valuation account that is used to present the net amount expected to be collected on a loan or lease. The ACL for loans and leases is adjusted through provision for credit losses as a charge against, or credit to, earnings. Loans and leases deemed to be uncollectible are charged against the ACL on loans and leases, and any subsequent recoveries are credited to the ACL. Management evaluates the ACL on a quarterly basis. When changes in the reserve are necessary, an adjustment is made. Management utilizes a discounted cash flow (DCF) model to calculate the present value of the expected cash flows for pools of loans and leases that share similar risk characteristics and compares the results of this calculation to the amortized cost basis to determine its allowance for credit loss balance. Management uses relevant available information, from internal and external sources, relating to past events, current conditions, and reasonable and supportable forecasts in calculating its ACL. Historical credit loss experience provides the basis for the estimation of expected credit losses. Management determines whether there is a need to make qualitative adjustments to historical loss information by monitoring certain factors including differences in current loan-specific risk characteristics as well as for changes in external or environmental conditions, or other relevant factors. The contractual term used in projecting the cash flows of a loan is based on the maturity date of a loan, and is adjusted for prepayment or curtailment assumptions which may shorten that contractual time period. Options to extend are considered by management in determining the contractual term. The key inputs to the DCF model are (1) probability of default, (2) loss given default, (3) prepayment and curtailment rates, (4) reasonable and supportable economic forecasts, (5) forecast reversion period, (6) expected recoveries on charged off loans, and (7) discount rate. Probability of Default (PD) In order to incorporate economic factors into forecasting within the DCF model, management elected to use the Loss Driver method to generate the PD rate inputs. The Loss Driver method analyzes how one or more economic factors change the default rate using a statistical regression analysis. Management selected economic factors that had strong correlations to historical default rates. Loss Given Default (LGD) Management elected to use the Frye Jacobs parameter for determining the LGD input, which is an estimation technique that derives a LGD input from segment specific risk curves that correlates LGD with PD. Prepayment and Curtailment rates Prepayment Rates: Loan level transaction data is used to calculate a quarterly prepayment rate for each of the most recent four quarters prior to the measurement date. Those quarterly rates are annualized and the average of the annualized rates is used in the DCF calculation for fixed payment or term loans. Rates are calculated for each pool. Curtailment Rates: Loan level transaction data is used to calculate annual curtailment rates using any available historical loan level data. The average of the historical rates is used in the DCF model for interest only payment or line of credit type loans. Rates are calculated for each pool. Reasonable and Supportable Forecasts The forecast data used in the DCF model is obtained via a subscription to a widely recognized and relied upon company who publishes various forecast scenarios. Management evaluates the various scenarios to determine a reasonable and supportable scenario. Forecast Reversion Period Management uses forecasts to predict how economic factors will perform and has determined to use a four quarter forecast period as well as a four quarter straight-line reversion period to historical averages (also commonly referred to as the mean reversion period). Expected Recoveries on Charged-off Loans Management performs an analysis to estimate recoveries that could be reasonably expected based on historical experience in order to account for expected recoveries on loans that have already been fully charged-off and are not included in the ACL calculation. Discount Rate The effective interest rate of the underlying loans and leases of the Corporation serves as the discount rate applied to the expected periodic cash flows. Management adjusts the effective interest rate used to discount expected cash flows to incorporate expected prepayments. Individual Evaluation Management evaluates individual instruments for expected credit losses when those instruments do not share similar risk characteristics with instruments evaluated using a collective (pooled) basis. Management individually analyzes these instruments and will establish a specific reserve for instruments as applicable. Instruments will not be included in both collective and individual analyses. All loans on nonaccrual status are individually evaluated for a specific reserve. Management considers a financial asset as collateral-dependent when the debtor is experiencing financial difficulty and repayment is expected to be provided substantially through the sale or operation of the collateral, based on management's assessment as of the reporting date. The allowance for credit losses on loans and leases is included within Allowance for credit losses, loans and leases on the condensed consolidated balance sheet. Changes in the allowance for credit losses on loans and leases are recorded within Provision for credit losses on the condensed consolidated statement of income.
Reserve for Unfunded Commitments	Reserve for Unfunded Commitments The Corporation maintains a reserve for off-balance sheet credit exposures such as unfunded commitments that are currently unfunded in categories with historical loss experience. Management calculates funding rates using loan level data history at the portfolio level. The most recent quarter’s (the actual measurement quarter) funding rate is subtracted from the maximum historical funding rate which is then applied to each pool’s total available line of credit. The applicable pool level loss rates for the current quarter is then applied to calculate the reserve for unfunded commitments liability each period. The reserve for off-balance sheet credit exposures is included within Accrued expenses and other liabilities on the condensed consolidated balance sheet. Changes in the reserve for off-balance sheet credit exposures are recorded within Provision for credit losses on the condensed consolidated statement of income.
