All customer statistics as of September 30, 2017 include the operations of Legacy TWC, Legacy Bright House and Legacy Charter, each of which is based on individual legacy company reporting methodology. These methodologies differ and their differences may be material. Statistical reporting will be conformed over time to a single reporting methodology. The following table summarizes our customer statistics for video, Internet and voice as of September 30, 2017 and 2016 (in thousands except per customer data and footnotes).

We calculate the aging of customer accounts based on the monthly billing cycle for each account. On that basis, as of September 30, 2017 and 2016, customers include approximately 218,300 and 200,900 customers, respectively, whose accounts were over 60 days past due, approximately 20,300 and 15,200 customers, respectively, whose accounts were over 90 days past due, and approximately 12,000 and 8,900 customers, respectively, whose accounts were over 120 days past due.
In the second quarter of 2017, we conformed the seasonal customer program in the Legacy Bright House footprint to our 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 our seasonal plan, residential customers pay a reduced monthly fee while the seasonal plan is active and remain reported as customers. Excluding the impact of net customer disconnect activity related to the previous seasonal plan, Legacy Bright House 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.
Customer relationships include the number of customers that receive one or more levels of service, encompassing video, Internet and voice services, without regard to which service(s) such customers receive. Customers who reside in residential multiple dwelling units (“MDUs”) and that are billed under bulk contracts are counted based on the number of billed units within each bulk MDU. Total customer relationships excludes enterprise customer relationships.
Monthly residential revenue per residential customer is calculated as total residential video, Internet and voice quarterly revenue divided by three divided by average residential customer relationships during the respective quarter.
Monthly small and medium business revenue per customer is calculated as total small and medium business quarterly revenue divided by three divided by average small and medium business customer relationships during the respective quarter.
Enterprise PSUs represent the aggregate number of fiber service offerings counting each separate service offering as an individual PSU.
