We define a "subscription" as a contract referencing a TiVo-enabled device for which (i) a consumer has committed to pay for the TiVo service and (ii) service is not canceled. We count product lifetime subscriptions in our subscription base until both of the following conditions are met: (i) the period we use to recognize product lifetime subscription revenues ends; and (ii) the related TiVo-enabled device has not made contact to the TiVo service within the prior six month period. Product lifetime subscriptions past this period which have not called into the TiVo service for six months are not counted in this total. Prior to November 1, 2011 we amortized all product lifetime subscriptions over a 60 month period. Effective November 1, 2011, we have extended the period we use to recognize product lifetime subscription revenues from 60 months to 66 months for product lifetime subscriptions where we have not recognized all of the related deferred revenue as of the reassessment date. We are not aware of any uniform standards for defining subscriptions and caution that our presentation may not be consistent with that of other companies. Additionally, the subscription fees that our MSOs pay us are typically based upon a specific contractual definition of a subscriber or subscription which may not be consistent with how we define a subscription for our reporting purposes nor be representative of how such subscription fees are calculated and paid to us by our MSOs. Our MSOs subscription data is based in part on reporting from our third-party MSO partners.

TiVo-Owned Churn Rate per Month.
Management reviews this metric, and believes it may be useful to investors, in order to evaluate our ability to retain existing TiVo-Owned subscriptions (including both monthly and product lifetime subscriptions) by providing services that are competitive in the market. Management believes factors such as service enhancements, service commitments, higher customer satisfaction, and improved customer support may improve this metric. Conversely, management believes factors such as increased competition, lack of competitive service features such as high definition television recording capabilities in our older model DVRs or access to certain digital television channels or MSO Video On Demand services, as well as increased price sensitivity and installation and CableCARD technology limitations, may cause our TiVo-Owned Churn Rate per month to increase.
We define the TiVo-Owned Churn Rate per month as the total TiVo-Owned subscription cancellations in the period divided by the Average TiVo-Owned subscriptions for the period (including both monthly and product lifetime subscriptions), which then is divided by the number of months in the period. We calculate Average TiVo-Owned subscriptions for the period by adding the average TiVo-Owned subscriptions for each month and dividing by the number of months in the period. We calculate the average TiVo-Owned subscriptions for each month by adding the beginning and ending subscriptions for the month and dividing by two. We are not aware of any uniform standards for calculating churn and caution that our presentation may not be consistent with that of other companies.
