Accounting Policies [Abstract] |
Summary of Significant Accounting Policies | NOTE 1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of presentation — The accompanying unaudited interim financial statements of WesBanco, Inc. and its consolidated subsidiaries (“WesBanco”) have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements and should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2018. WesBanco’s interim financial statements have been prepared following the significant accounting policies disclosed in Note 1 of the Notes to the Consolidated Financial Statements of its 2018 Annual Report on Form 10-K filed with the Securities and Exchange Commission. In the opinion of management, the accompanying interim financial information reflects all adjustments, including normal recurring adjustments, necessary to present fairly WesBanco’s financial position and results of operations for each of the interim periods presented. Certain prior period amounts have been reclassified to conform to the current period presentation. Such reclassifications had no impact on WesBanco’s net income and stockholders’ equity. Results of operations for interim periods are not necessarily indicative of the results of operations that may be expected for a full year. Recent accounting pronouncements — In August 2018, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 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.” This ASU specifically 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 and hosting arrangements that include an internal-use software license. The ASU does not affect the accounting for the service element of a hosting arrangement that is a service contract. The guidance is effective for fiscal years beginning after December 15, 2019 and interim periods within those fiscal years. Early adoption is permitted, including adoption in an interim period. WesBanco is currently assessing the impact of ASU 2018-15 on WesBanco’s Consolidated Financial Statements. ASU 2018-14 Compensation—Retirement Benefits—Defined Benefit Plans—General (Topic 715-20) In August 2018, the FASB issued ASU 2018-14, “Compensation—Retirement Benefits—Defined Benefit Plans—General (Topic 715-20): Disclosure Framework—Changes to the Disclosure Requirements for Defined Benefit Plans.” This ASU modifies Accounting Standards Codification (“ASC”) 715-20 to improve disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans. The guidance is effective for fiscal years ending after December 15, 2020. Early adoption is permitted. WesBanco is currently assessing the impact of ASU 2018-14 on WesBanco’s Consolidated Financial Statements. ASU 2018-13 Fair Value Measurement – Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement In August 2018, the FASB issued ASU 2018-13, “Fair Value Measurement – Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement.” This ASU modifies the disclosure objective paragraphs of ASC 820 to eliminate (1) “at a minimum” from the phrase “an entity shall disclose at a minimum” and (2) other similar “open ended” disclosure requirements to promote the appropriate exercise of discretion of entities. The guidance is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. Early adoption is permitted, including adoption in an interim period. WesBanco is currently assessing the impact of ASU 2018-13 on WesBanco’s Consolidated Financial Statements. ASU 2016-13 Financial Instruments – Credit Losses (Topic 326) In September 2016, the FASB issued ASU 2016-13, “Financial Instruments – Credit Losses (Topic 326),” which will require entities to use a new forward-looking “expected loss” model also referred to as the current expected credit loss model (“CECL”) on trade and other receivables, held-to-maturity debt securities, loans and other instruments that generally will result in the earlier recognition of allowances for credit losses. For available-for-sale debt securities with unrealized losses, entities will measure credit losses in a manner similarly to current procedures, except that the losses will be recognized as allowances rather than reductions in the amortized cost of the securities. Entities will have to disclose significantly more information, including information they use to track credit quality by year of origination for most financing receivables. In April 2019, the FASB issued ASU 2019-04, “Codification Improvements to Topic 326, Financial Instruments – Credit Losses, Topic 815, Derivatives and Hedging and Topic 825, Financial Instruments” and in May 2019 the FASB issued ASU 2019-05, “Financial Instruments – Credit Losses (Topic 326), Targeted Transition Relief. Public business entities must apply the new requirements for fiscal years beginning after December 15, 2019, including interim periods within those fiscal years, which for WesBanco will be effective for the fiscal year beginning January 1, 2020. Early adoption is permitted for fiscal years beginning after December 15, 2018. In December 2018, the Board of Governors of the Federal Reserve System, the Federal Deposit Insurance Corporation (“FDIC”) and the Office of Comptroller of the Currency (“OCC”) approved a final rule to address changes to credit loss accounting under GAAP, including banking organizations’ adoption of the CECL methodolgy. The final rule provides banking organizations the option to phase-in, over a three-year period, the day-one adverse effects on regulatory capital that may result from the adoption of the new accounting standard. WesBanco is continuing to analyze the impact of the adoption of this standard on the company’s regulatory capital to determine the best course of action regarding immediate or delayed recognition of the day-one adoption adjustment upon regulatory capital. Under CECL, acquired loans or pools of loans that have experienced more-than-insignificant credit deterioration are deemed to be purchased credit deteriorated (“PCD”) loans, and are grossed-up on day 1 by the initial credit estimate through the allowance as opposed to a reduction in the loan’s amortized cost. The credit mark on acquired loans deemed not to be PCD loans will be reflected as a reduction in the loan’s amortized cost, with an allowance and corresponding provision for credit losses recorded in the first reporting period after acquisition through current period earnings, while the loan mark will accrete through interest income over the life of such loans. At acquisition, WesBanco will consider several factors as indicators that an acquired loan or pool of loans has experienced more-than-insignificant credit deterioration. These factors may include loans 30 days or more past due, loans with an internal risk grade of below average or lower, loans classified as non-accrual by the acquired institution, materiality of the credit and loans that have been previously modified in a troubled debt restructuring (“TDR”). Upon adoption of this standard, acquired loans from prior acquisitions that m e et the guidelines under ASC 310-30 (formerly known as “purchased credit impaired”) will be reclassified as PCD loans. The accretable portion of the loan mark as of adoption date will continue to accrete into interest income. However, the non-accretable portion of the loan mark will be added to the allowance upon adoption, and any reversals of such mark will flow through the allowance in future periods. The loan mark on ASC 310-20 loans (“non-purchased credit impaired”) from prior acquisitions will continue to accrete through interest income over the life of such loans. WesBanco formed a cross-functional team in 2016 to oversee the implementation of CECL. The team was responsible for completing an initial data gap assessment, determining if additional data was needed or current data could be improved upon, finalizing the loan segmentation procedures, analyzing the methodology options regarding the calculation of expected credit losses and concluding why the selected methodology is reasonable and in-line with accounting guidance. WesBanco has completed a parallel run for the third quarter of 2019 to ensure the various forecasting and modeling assumptions are reasonable and supportable, including certain qualitative factors that have been developed to estimate the initial current expected credit loss allowance. WesBanco will continue to perform parallel runs throughout the remainder of 2019 prior to adoption of the ASU. Based on preliminary analysis performed during 2019, using forecasts and macroeconomic conditions and exposures during that time and with qualitative factors and model validation still in process, the overall Day 1 range of potential outcomes is estimated to result in an increase of up to 30% in the CECL allowance for credit losses for the loan portfolio. This estimation is derived from the selected assumption of a one-year reasonable and supportable forecast. After the forecast period, WesBanco reverts back over a three year period to historical loss rates adjusting for prepayments and curtailments, to estimate losses over the remaining life of loans. The most sensitive assumptions include the length of the forecast and reversion periods, forecast of unemployment and interest rate spreads and prepayment speeds. The ultimate impact will depend on the composition of the loan portfolio, credit quality of the loan portfolio and the macroeconomic conditions and forecasts utilized in the calculation of the allowance of credit losses for loans. WesBanco has engaged a third-party to validate the data inputs and the models utilized in the CECL calculation. The final results of the model validation, as well as further refinement of judgmental factors are still in process and could materially impact the estimated range of potential outcomes noted above. The Company has prepared documentation of the accounting policy decisions, changes to the business processes and procedures, and the control environment under the adoption of this standard, and has drafted the format of the initial, upon adoption footnote disclosure, to be included in the Form 10-Q for the first quarterly period after adoption, or as of March 31, 2020. Upon adoption, the Company estimates the impact on the Tier 1 risk-based capital ratio would be up to a 15 basis point reduction, based on the assumptions noted above, without a phase-in assumed of the regulatory capital impact over three years. None of the above noted evaluation assumptions and initial estimates include the acquired loans from Old Line Bancshares, Inc. (“Old Line”) or any related allowance impact. If the acquisition of Old Line closes before year-end, the acquired loan portfolio will be accounted for under existing acquired loan portfolio and allowance rules; however, if the acquisition closes after December 31, 2019, the new CECL rules will apply as noted above for PCD and non-PCD loans. WesBanco will recognize an allowance for credit losses for held-to-maturity (“HTM”) debt securities. Based on the credit quality of WesBanco’s HTM debt securities’ portfolio, WesBanco does not expect the allowance for credit losses to be significant for HTM securities. ASU 2016-02 Leases (Topic 842) In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842),” which requires entities to recognize lease assets and lease liabilities on the balance sheet and disclose key information about leasing arrangements. The principal difference from previous guidance is that the lease assets and lease liabilities arising from operating leases were not previously recognized in the balance sheet. Public business entities must apply the new requirements for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. For WesBanco, this update was effective for the fiscal year beginning January 1, 2019. In January 2018, the FASB issued ASU 2018-01, which allows entities the option to apply the provisions of the new lease guidance at the effective date without adjusting the comparative periods presented. In July 2018, the FASB issued ASU 2018-10, which provides narrow-scope improvements to the lease standard and ASU 2018-11, which allows entities to choose an additional transition method, under which an entity initially applies the new lease standard at the adoption date and recognizes a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. Under this transitional method, the entity shall recognize and measure the leases that exist at the adoption date and the prior comparative periods are not adjusted. WesBanco adopted this ASU as of January 1, 2019 using the transitional method. In addition, WesBanco utilized certain practical expedients including the following - retained the classifications of existing leases, no re-assessment to determine if existing leases have initial direct costs and utilized hindsight when determining the lease term and assessment of impairment in existing leases. WesBanco initially capitalized $20 million upon adoption for right-of-use assets and lease liabilities, net of existing straight-line lease liabilities and unfavorable acquired lease liabilities. See additional disclosures in Note 6, “Leases.” ASU 2017-12 Targeted Improvements to Accounting for Hedging Activities In August 2017, the FASB issued ASU 2017-12, “Targeted Improvements to Accounting for Hedging Activities.” The new guidance makes more financial and nonfinancial hedging strategies eligible for hedge accounting. It also amended the presentation and disclosure requirements and changed how companies assess effectiveness. It was intended to more closely align hedge accounting with companies’ risk management strategies, simplify the application of hedge accounting, and increase transparency as to the scope and results of hedging programs. The guidance was effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. For WesBanco, this update was effective for the fiscal year beginning January 1, 2019. Upon adoption, WesBanco reclassified $67.3 million of callable held-to-maturity municipal debt securities to available-for-sale debt securities. ASU 2018-16 D erivatives 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 In October 2018, the FASB issued ASU 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 ASU modifies ASC 815 for eligible benchmark interest rates. Due to concerns about the sustainability of the London Interbank Offered Rate (LIBOR), the Federal Reserve Board initiated an effort to introduce an alternative reference rate in the United States. The Overnight Index Swap (OIS) rate, which is based on SOFR is permitted as a U.S. benchmark interest rate for hedge accounting purposes. The guidance was effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. For WesBanco, this update was effective for the fiscal year beginning January 1, 2019. The adoption of this pronouncement did not have a material impact on WesBanco’s Consolidated Financial Statements.
