The Company did not appropriately account for the disposal group as a stock sale. Consequently, certain income tax account balances (primarily related to deferred tax liabilities) were not classified as assets and liabilities held for sale in the Company’s Consolidated Balance Sheet at December 31, 2018. As a result, the Company determined its book-over-tax outside basis differences and measured the tax effects of such difference, which resulted in an income tax expense of approximately </span><span style="font-family:inherit;font-size:10pt;"><span>$12.6 million</span></span><span style="font-family:inherit;font-size:10pt;">. In addition, the Company did not use an accurate estimate of fair value in its 2018 impairment testing. Collectively, the estimate of fair value and expected form of sale resulted in adjustments to the estimated fair value and carrying value of the held for sale business utilized in the Company’s 2018 impairment testing. These changes resulted in an additional impairment charge of approximately </span><span style="font-family:inherit;font-size:10pt;"><span>$12.0 million</span></span><span style="font-family:inherit;font-size:10pt;"> to write-down the carrying value of the net assets of the held for sale business to its estimated fair value at December 31, 2018.</span></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;">In addition, as part of the presentation of discontinued operations, the Company periodically has to reclassify the prior period presentation to conform to the current year presentation. These adjustments are reflected in the Reclassification column below, which includes the Commercial Business that the Company decided to retain upon Board of Directors’ approval in the Third Quarter 2019 and the Fourth Quarter 2019.</span></div><div style="line-height:120%;text-align:justify;font-size:10pt;"><span style="font-family:inherit;font-size:10pt;"><br/></span></div>
