The corresponding prior period amounts have been reclassified to conform with the current period presentation. 2 The Income tax benefit in Q4'17 is primarily due to the remeasurement of deferred tax liabilities as a result of the Tax Cuts and Jobs Act (the "Act") signed into law on December 22, 2017. The resulting net tax benefit is included in the three months ended December 31, 2017. The Act is complex and significantly changes the U.S. corporate income tax system by, among other things, reducing the Federal corporate income tax rate from 35% to 21%.

The corresponding prior period amounts have been reclassified to conform with the current period presentation. 2 Adjusted operating income (loss) excludes the impact of the items listed that we do not believe are indicative of our core operating performance.3 Operating income for Q3'18 includes $22.9 million for the gain on divested assets, net.

ADJUSTED NET EARNINGS & ADJUSTED NET EARNINGS PER DILUTED COMMON SHARE RECONCILIATION OF NON-GAAP FINANCIAL MEASURES (UNAUDITED) 1 All non-tax items are tax effected at the expected annual rate for that period.2 Adjusted net earnings and Adjusted net earnings per diluted common share exclude the impact of the items listed that we do not believe are indicative of our core operating performance. 3 The federal tax rate change in Q4'17 is primarily due to the remeasurement of deferred tax liabilities as a result of the Tax Cuts and Jobs Act (the "Act") signed into law on December 22, 2017. The resulting net tax benefit is included in the three months ended December 31, 2017. The Act is complex and significantly changes the U.S. corporate income tax system by, among other things, reducing the Federal corporate income tax rate from 35% to 21%.

EBITDA & ADJUSTED EBITDA RECONCILIATION OF NON-GAAP FINANCIAL MEASURES (UNAUDITED) 1 EBITDA is a non-GAAP measure that management uses as a supplemental performance measure. The most directly comparable GAAP measure is net earnings. EBITDA is net earnings adjusted for net interest expense, income taxes, and depreciation and amortization.
