There are certainly redflags in its financial reports. For one, CCME's revenue grew more than 24 fold from 2006 to 2009 while its sales force almost remained flat.
CCME reported revenues of $4 million, $26 million, 63 million and $95 million for year 2006 2007, 2008 and 2009, correspondingly. The reported people in sale force for 2006, 2007, 2008 and 2009 are 58, 76, 63# and 63, correspondingly.
#: 63 in 2009 is the reported number on June, 2009. 2008 number is a approximation based on the statement "There were no significant difference in the size of the sales force for the six months ended June 30, 2009 and 2008" on page 148 of form DEFM14a.
One can argue that CCME just charge more per ad as it expands its network. Thus, it can increase revenue without increasing sale force. This is good just for the national advertisers, like COKE or GM. Most advertisers are local to provincial markets. As CCME expands to more provincial markets, it need to add sales force to that market.
Anyway, same number of sales people handle sales from 4 million to 95 million. Maybe, it makes sense for certain industries, but it is beyond my knowledge to understand it. I put it on the too hard pile.
