Goodwill and Intangible Assets Disclosure [Abstract] |
Goodwill | GOODWILL Goodwill is recorded on the acquisition date of an entity. During the one-year measurement period, the Corporation may record subsequent adjustments to goodwill for provisional amounts recorded at the acquisition date. The MBT acquisition on September, 1, 2019 resulted in $98,563,000 of goodwill, which includes a measurement period adjustment of $719,000 recorded in the fourth quarter of 2019. Details regarding the MBT acquisition are discussed in NOTE 2. ACQUISITIONS of these Notes to Consolidated Financial Statements. There have been no changes in goodwill since December 31, 2019, resulting in a goodwill balance of $543,918,000 as of December 31, 2020. The Corporation reviews goodwill annually for impairment, or more frequently if events or circumstances indicate the carrying value might be impaired. The impairment analysis compares the estimated fair value of the Corporation (the reporting unit) with the Corporation's net book value. On January 1, 2020, the Corporation adopted ASU No. 2017-04, Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill. Subsequent to the October 1, 2019 impairment test and adoption of ASU 2017-04, the Corporation experienced a decline in market capitalization as a result of a decline in the share price of the Corporation's common stock. At March 31, 2020, June 30, 2020 and September 30, 2020, the Corporation assessed the economic impact and market conditions from the COVID-19 pandemic. Additionally, the Corporation assessed the general uncertainty as to the full extent of the COVID-19 pandemic and its effect on economic recovery and concluded goodwill was not impaired in either period. As of October 1, 2020, the Corporation performed its annual goodwill impairment test which included various valuation considerations including comparable peer data, precedent transaction comparables, discounted cash flow analysis, overall financial performance, share price of the Corporation's common stock and other factors. The testing for both periods resulted in a conclusion that it was not more likely than not that the fair value of the Corporation had declined below its carrying value and no impairment loss was recorded in 2020. In December 2020, the Corporation's stock price increased to a value higher than its carrying value and has remained at these levels. The Corporation considers this further support the decline in stock value was considered temporary and not an indication goodwill was impaired. Goodwill assessments are highly sensitive to economic projections and the related assumptions used by management. In the event of a prolonged economic downturn or further deterioration in the economic outlook, continued assessments of our goodwill balance will likely be required in future periods. The Corporation also conducted its annual goodwill impairment testing in 2019. In the valuation, the fair value exceeded the Corporation's carrying value; therefore, it was concluded goodwill was not impaired.
