A membership (also referred to as a subscription) is defined as the right to receive Netflix service following sign-up and a method of payment being provided. Memberships are assigned to territories based on the geographic location used at time of sign-up as determined by the Company's internal systems, which utilize industry standard geo-location technology. The Company offers free-trial memberships to certain new and rejoining members. Total members include those who are on a free-trial as long as a method of payment has been provided. A membership is canceled and ceases to be reflected in the above metrics as of the effective cancellation date. Voluntary cancellations become effective at the end of the prepaid membership period, while involuntary cancellation of the service, as a result of a failed method of payment, becomes effective immediately.
