Sees stronger sequential CNS revenue growth and continued double digit adjusted EBITDA growth in 2013. The company says "For the first quarter 2013, we expect to see a slight decline in CNS revenue on a sequential basis, due to the typical reversal in the seasonally strong fourth quarter revenue. Adjusting for the special items in the fourth quarter, with the expected decline in CNS revenue and increase in payroll taxes, we expect Adjusted EBITDA to be roughly flat in the first quarter 2013 compared to the fourth quarter 2012. For the remainder of 2013, we generally expect sequential CNS revenue growth to be stronger compared to 2012. We expect low double digit percentage growth in Adjusted EBITDA, compared to full year 2012 reported Adjusted EBITDA of $1.459 billion. We expect to be Free Cash Flow positive for the full year, excluding interest rate swap obligations."
