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 (loss).

It should not be considered as an alternative to net earnings (loss) computed under GAAP.2 Interest expense, net for the fourth quarter of 2016 includes debt retirement costs of $0.4 million.3 Adjusted EBITDA excludes the impact of the items listed that we do not believe are indicative of our core operating performance.
