Interest expense will now be deducted from Adjusted EBITDA instead of Cash paid for interest expense, net. This change will remove the quarterly timing effects of cash interest payments during the year and include the impact of amortized debt costs. In addition, other non-cash amounts that affect net income will be an adjustment to Adjusted EBITDA, as appropriate. 48
