Spatch, the numbers you're throwing-out there are killing me. Let's take a look and figure this one out. Dish Network's monthly churn rate during 2007 was 1.70% per month. Multiply this times 12 and roughly 20.4% of Dish Network's customers decided to terminate their service. These numbers are taken directly from EchoStar's 2007 Annual Report.
Dish Network ended 2007 with 13,780,000 customers. Based on last years churn rate of 1.70% per month, and assuming the churn rate remains constant, Dish Network can expect roughly 234,260 customers to cancel service during any given month, or around 2,811,120 customers expected to leave Dish Network during 2008.
Now, if the churn rate for 2008 has risen 15% as stated (1.70 x 1.15) that means the new churn rate is something like 1.955% per month or 23.46% annually. In a nutshell, roughly 269,399 customers are now leave Dish Network each month or 3,232,788 annually.
3,232,788 - 2,811,120 is a difference of 421,668 more customers apparently leaving Dish Network this year for a difference of 15% (421,688 / 2,811,120). So, it would appear more than 421K are leaving Dish Network this year...hence, why Charlie is standing-up a special call center to attempt to retain some of these customers.
Dish Network is still signing-up new customers, but the rate at which they are leaving picked-up during 2007 (according the the 2007 Annual Report) and has been getting 15% worse so far this year.
Anyway, that's my quick take on the 15% increase in churn. Please feel to correct me if I am wrong...I certainly don't do this stuff for a living.
