Income from continuing operations includes a benefit of approximately $11,400 in the third quarter of 2018 for the release of valuation allowance against state NOLs. A similar amount was recorded as an expense in the fourth quarter of 2018 as a valuation allowance against state NOLs for a change in enacted tax laws. The Company adopted ASC 606 – Revenue from Contracts with Customers on January 1, 2018 using the modified retrospective method which does not require comparative periods, reported under ASC 605, to be restated.

(2)	Income from continuing operations includes expense of $117 in the fourth quarter of 2017 as a result of the change in enacted tax rates in the U.S. and the toll tax.

(3)	Discontinued operations include charges and reimbursements for environmental remediation related to sites of divested businesses.

(4)	Earnings per share calculations for each of the quarters are based on the weighted average number of shares outstanding for each period. As such, the sum of the quarters may not necessarily equal the earnings per share amount for the year.
