Historically, the company has paid 60 percent of employee annual bonuses in stock compensation and 40 percent in cash. Beginning in 2014, the company will accrue the entire bonus compensation within SG&A as cash compensation. Had the company made this change in 2013, there would have been an increase in cash compensation expense within SG&A of $59 million, offset by an equal decrease in non-cash compensation expense, and Adjusted EBITDA would have been $1.565 billion, pro forma for the change.
