CSG Systems International (NASDAQ:CSGS) has expanded and extended its relationship with Comcast (NASDAQ:CMCSA) to provide residential billing services through June 30, 2019. Currently, CSG provides its customer care and billing solution to approximately two-thirds of Comcast's existing residential customers.

The expanded contract provides the framework for Comcast to consolidate its residential business onto CSG's billing solution. Initially under the new agreement, Comcast plans to add approximately 2.3 million residential customers onto the CSG billing solution in early 2015, with the opportunity for additional customer account migrations to CSG as part of any future consolidation or standardization.
