(a)
Represents the estimated number of single residence homes, apartments and condominium units passed by the cable distribution network in areas serviceable without further extending the transmission lines. In addition, it includes commercial establishments that have connected to our cable distribution network. For Cequel, broadband services were not available to approximately 100 homes passed and telephony services were not available to approximately 500 homes passed. 
(b)
Represents number of households/businesses that receive at least one of the Company's services. 
(c)
Customers represent each customer account (set up and segregated by customer name and address), weighted equally and counted as one customer, regardless of size, revenue generated, or number of boxes, units, or outlets. In calculating the number of customers, we count all customers other than inactive/disconnected customers. Free accounts are included in the customer counts along with all active accounts, but they are limited to a prescribed group. Most of these accounts are also not entirely free, as they typically generate revenue through pay-per-view or other pay services. Free status is not granted to regular customers as a promotion. In counting bulk residential customers, such as an apartment building, we count each subscribing family unit within the building as one customer, but do not count

the master account for the entire building as a customer. We count a bulk commercial customer, such as a hotel, as one customer, and do not count individual room units at that hotel.
(d)
Represents the number of customers that subscribe to three of our services divided by total residential customer relationships. 
(e)
Represents the number of total customer relationships divided by homes passed. 
(f)
Calculated by dividing the average monthly revenue for the respective quarter (fourth quarter for annual periods) presented derived from the sale of broadband, pay television and telephony services to residential customers for the respective quarter by the average number of total residential customers for the same period.
