CEO Lew Dickey says much of that year-to-year decline was because of the political revenues that Cumulus enjoyed in 2006. Cumulus joins the parade of public companies reporting impairment charges - writedowns on the value of stations in some markets - of $149.3 million. The Atlanta-based operator is still in the process of trying to go private, in a deal led by Merrill Lynch, and so Dickey didn't hold a conference call today. But the Cumulus does say 2008 is starting off better - "revenue for the first quarter is currently pacing up 3%, and [it] expects station operating expenses will be down slightly."
