In the second quarter of 2017, Charter conformed the seasonal customer program in the Legacy Bright House footprint to Charter's program. Prior to the plan change, Legacy Bright House customers enrolling in the seasonal plan were charged a one-time fee and counted as customer disconnects, and as new connects, when moving off the seasonal plan. Under Charter's seasonal plan, residential customers pay a reduced monthly fee while the seasonal plan is active and remain reported as customers. Excluding the impact of customer connect activity related to Legacy Bright House residential customers moving off the seasonal plan, net additions for video, Internet and voice PSUs for the third quarter of 2016 would have been lower by 4,000, 6,000 and 4,000, respectively. Excluding the net disconnect activity in the second and third quarters of 2016, residential customer relationships, video, Internet and voice PSUs at September 30, 2016 would have been higher by approximately 54,000, 48,000, 66,000 and 45,000, respectively.
