Accounting Changes and Error Corrections [Abstract]
Accounting Standards Updates and Recently Adopted Standards	Accounting Standards Updates and Recently Adopted Standards Accounting Standards Updates In February 2016, the FASB issued Accounting Standards Update (“ASU”) No. 2016-02, Leases (Topic 842). This guidance was further modified in 2018 by ASU No. 2018-10, Codification Improvements to Topic 842 Leases, ASU No. 2018-11, Leases (Topic 842): Targeted Improvements, and ASU No. 2018-20, Leases (Topic 842): Narrow-Scope Improvements for Lessors. These standards require a lessee to recognize in the consolidated balance sheet a liability to make lease payments (the lease liability) and a right-of-use asset representing its right to use the underlying asset for the lease term. United adopted the standard on January 1, 2019 using the optional transition method, which allowed for a modified retrospective method of adoption with a cumulative effect adjustment to shareholders’ equity without restating comparable periods. United also elected the relief package of practical expedients for which there is no requirement to reassess existence of leases, their classification, and initial direct costs as well as an exemption for short-term leases with a term of less than one year, whereby United does not recognize a lease liability or right-of-use asset on the consolidated balance sheet but instead recognizes lease payments as an expense over the lease term as appropriate. The adoption of this guidance resulted in recognition of a right-of-use asset of $23.7 million, a lease liability of $26.7 million and a reduction of shareholders’ equity of $738,000. In the opinion of management, the changes described above resulting from the adoption of the standard did not have a material impact on the consolidated financial statements. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. This guidance was further modified in November 2018 by ASU No. 2018-19, Codification Improvements to Topic 326, Financial Instruments - Credit Losses. The new guidance replaces the incurred loss impairment methodology in current GAAP with an expected credit loss methodology and requires consideration of a broader range of information to determine credit loss estimates. Financial assets measured at amortized cost will be presented at the net amount expected to be collected by using an allowance for credit losses. Purchased credit impaired loans will receive an allowance account at the acquisition date that represents a component of the purchase price allocation. Credit losses relating to available-for-sale debt securities will be recorded through an allowance for credit losses, with such allowance limited to the amount by which fair value is below amortized cost. Application of this update will primarily be on a modified retrospective approach, although the guidance for debt securities for which an other-than-temporary impairment has been recognized before the effective date and for loans previously covered by ASC 310-30, Receivables – Loans and Debt Securities Acquired with Deteriorated Credit Quality will be applied on a prospective basis. For public entities, this update is effective for fiscal years beginning after December 15, 2019. Upon adoption, United expects that the allowance for credit losses may be higher given the change to estimated losses for the estimated life of the financial asset; however, management is still in the process of determining the impact. Management has formed a steering committee and completed a gap assessment and a full project plan. The steering committee has selected a software provider and is in the process of populating relevant data, building models and documenting processes and controls in preparation for a loan-focused parallel run in the first quarter of 2019. United expects to run a full parallel run for the remaining three quarters of 2019 to ensure it is prepared for implementation by the effective date. During monthly steering committee meetings, management regularly reviews project status, gap remediation efforts and project priorities. In March 2017, the FASB issued ASU No. 2017-08, Receivables – Nonrefundable Fees and Other Costs (Subtopic 310-20): Premium Amortization on Purchased Callable Debt Securities. This update shortens the amortization period for certain callable debt securities held at a premium. Specifically, the amendments require the premium to be amortized to the earliest call date. For securities held at a discount, the discount will continue to be amortized to maturity. For public entities, this update is effective for fiscal years beginning after December 15, 2018, with modified retrospective application. The adoption of this update on January 1, 2019 did not have a material impact on the consolidated financial statements. In August 2017, The FASB issued ASU No. 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities. This update expands and refines hedge accounting for both nonfinancial and financial risk components and aligns the recognition and presentation of the effects of the hedging instrument and the hedged item in the financial statements. This update also makes certain targeted improvements to simplify the application of hedge accounting guidance and ease the administrative burden of hedge documentation requirements and assessing hedge effectiveness. For public entities, this update is effective for fiscal years beginning after December 15, 2018. For cash flow and net investment hedges existing at the date of adoption, an entity should apply a cumulative-effect adjustment related to eliminating the separate measurement of ineffectiveness to accumulated other comprehensive income with a corresponding adjustment to the opening balance of retained earnings. The amended presentation and disclosure guidance is required prospectively. The adoption of this update on January 1, 2019 did not have a material impact on the consolidated financial statements. In May 2018, the FASB issued ASU No. 2018-06, Codification Improvements to Topic 942, Financial Services - Depository and Lending. This update superseded outdated guidance related to the Office of the Comptroller of the Currency’s Banking Circular 202, Accounting for Net Deferred Tax Charges. United does not expect the new guidance to have a material impact on the consolidated financial statements. In June 2018, the FASB issued ASU No. 2018-07, Compensation - Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting. This update expands the scope of Topic 718 to include share-based payment transactions for acquiring goods and services from nonemployees. As a result, nonemployee share-based payment awards will be measured at the grant-date fair value of the equity instruments that an entity is obligated to issue when the service has been rendered, subject to the probability of satisfying performance conditions when applicable. For public entities, this update is effective for fiscal years beginning after December 15, 2018. The adoption of the new guidance on January 1, 2019 did not have a material impact on the consolidated financial statements as United does not currently grant equity awards to nonemployees other than directors and does not anticipate doing so. In June 2018, the FASB issued ASU No. 2018-08, Not for Profit Entities (Topic 958): Clarifying the Scope and the Accounting Guidance for Contributions Received and Contributions Made. This update clarifies the guidance about whether a transfer of assets (or the reduction, settlement or cancellation of liabilities) is a contribution or an exchange transaction. In addition, the guidance clarifies the determination of whether a transaction is conditional. For public entities, this update is effective for contributions made in fiscal years beginning after December 15, 2018. The adoption of the new guidance on January 1, 2019 did not have a material impact on the consolidated financial statements. In July 2018, the FASB issued ASU No. 2018-09, Codification Improvements to address stakeholder suggestions for minor corrections and clarifications within the codification. The transition and effective date guidance is based on the facts and circumstances of each amendment. Some of the amendments in this update do not require transition guidance and will be effective upon issuance of this update. However, many of the amendments in this update do have transition guidance with effective dates for annual periods beginning after December 15, 2018, for public business entities. The adoption of the new guidance on January 1, 2019 did not have a material impact on the consolidated financial statements. 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. The update removes disclosures that are no longer considered cost beneficial, modifies certain requirements of disclosures, and adds disclosure requirements identified as relevant. For public entities, this guidance is effective for fiscal years ending after December 15, 2019 and, depending on the provision, requires either prospective or retrospective application to prior periods presented. United does not expect the new guidance to have a material impact on the consolidated financial statements. 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 update removes disclosures that are no longer considered cost beneficial, clarifies specific requirements of disclosures, and adds disclosure requirements identified as relevant. For public entities, this guidance is effective for fiscal years ending after December 15, 2020 and requires retrospective application to prior periods presented. United does not expect the new guidance to have a material impact on the consolidated financial statements. In August 2018, the FASB issued ASU No. 2018-15, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract (a consensus of the FASB Emerging Issues Task Force). This update aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal use software. For public entities, this guidance is effective for fiscal years ending after December 15, 2019 with either retrospective or prospective application. United does not expect the new guidance to have a material impact on the consolidated financial statements. In October 2018, the FASB issued ASU No. 2018-16, Derivatives and Hedging (Topic 815): Inclusion of the Secured Overnight Financing Rate (SOFR) Overnight Index Swap (OIS) Rate as a Benchmark Interest Rate for Hedge Accounting Purposes. This update permits the use of the OIS rate based on SOFR as a U.S. benchmark interest rate for hedge accounting purposes. For public entities, this guidance is effective for fiscal years beginning after December 15, 2018 and should be applied on a prospective basis for qualifying new or redesignated hedging relationships. The adoption of this update on January 1, 2019 did not have a material impact on the consolidated financial statements. In October 2018, the FASB issued ASU No. 2018-17, Consolidation (Topic 810): Targeted Improvements to Related Party Guidance for Variable Interest Entities. In addition to expanding the private company accounting alternative for applying variable interest entities (“VIE”) guidance, this update modifies the evaluation of decision-making fees for all entities applying VIE guidance. For public entities, this guidance is effective for fiscal years beginning after December 31, 2019 with retrospective application. United does not expect the new guidance to have a material impact on the consolidated financial statements. Standards Adopted in 2018 In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers. This ASU provides guidance on the recognition of revenue from contracts with customers. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. This guidance was effective for public entities for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period, and was applied retrospectively either to each prior reporting period or with a cumulative effect recognized at the date of initial application. On January 1, 2018, United adopted ASU 2014-09 and all subsequent amendments to the ASU (collectively, ASC 606) using the modified retrospective approach. Because the guidance did not apply to revenue associated with financial instruments, including loans, leases, derivatives and securities, and revenue sources within scope were not materially affected, the new revenue recognition guidance did not have a material impact on the consolidated financial statements. In January 2016, the FASB issued ASU 2016-1, Financial Instruments – Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Liabilities. The guidance in this update requires that equity investments (except those accounted for under the equity method of accounting) be measured at fair value with changes in fair value recognized in net income. However, an entity may choose to measure equity investments that do not have readily determinable fair values at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer. The guidance also simplifies the impairment assessment of equity investments without readily determinable fair values by requiring a qualitative assessment to identify impairment. In addition, the guidance addresses various disclosure and presentation issues related to financial instruments. For public entities, this update was effective for fiscal years beginning after December 15, 2017 with early application permitted. The adoption of this update did not have a material impact on the consolidated financial statements. There was no opening balance sheet adjustment as a result of the adoption and the remainder of the standard was applied prospectively. In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash (a consensus of the FASB Emerging Issues Task Force). This ASU requires that the statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. This guidance was effective for public entities for fiscal years beginning after December 15, 2017, including interim periods within that reporting period, and was applied retrospectively to each period presented. The adoption of this update did not have a material impact on the consolidated financial statements. There was no adjustment to prior periods as a result of the adoption. In March 2017, the FASB issued ASU No. 2017-07, Compensation – Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. This ASU requires that an employer disaggregate the service cost component from the other components of net benefit cost. The amendments also provide explicit guidance on how to present the service cost component and the other components of net benefit cost and allow only the service cost component to be eligible for capitalization. For public entities, this update was effective for fiscal years beginning after December 15, 2017, with retrospective presentation of the service cost and other components and prospective application for any capitalization of service cost. The adoption of this update did not have a material impact on the consolidated financial statements. In May 2017, the FASB issued ASU No. 2017-09, Compensation – Stock Compensation (Topic 718): Scope of Modification Accounting. This update clarifies which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting. Specifically, modification accounting should be applied unless the fair value of the modified award is the same as the original award immediately before modification, the vesting conditions of the modified award are the same as the original award immediately before modification, and the classification of the modified award as an equity instrument or a liability instrument is the same as the classification of the original award immediately before modification. For public entities, this update is effective for fiscal years beginning after December 15, 2017, with prospective application. The adoption of this update did not have a material impact on the consolidated financial statements.
