The New York State Department of Public Service today announced it had reached a potential settlement with Charter Communications after the company failed to meet its rural broadband expansion obligation outlined in last year’s approval of its acquisition of Time Warner Cable.

“The [Public Service] Commission conditioned its approval of the merger on Charter’s agreement to undertake several types of investments and other activities,” said Department interim CEO Gregg C. Sayre. “While Charter is delivering on many of them, it failed to expand the reach of its network to un-served and under-served communities and commercial customers in the time allotted.”

While Charter’s merger with Time Warner Cable and Bright House Networks won rubber-stamp approval in almost every state where it operates, New York regulators required the merger to directly benefit the state’s consumers. The company must upgrade customers to 100Mbps service by the end of 2018 and offer at least 300Mbps statewide by the end of 2019. But it must also expand its cable network to reach 145,000 unserved and underserved homes and businesses within the next four years. The merger approval agreement set a schedule to begin network expansion as quickly as possible.

Charter failed to achieve its obligations, only reaching 15,164 of the 36,250 customers it was required to reach one year after the merger deal was approved.

As a result, regulators have penalized Charter, requiring it to pay an extra $1 million in grants for computer equipment and internet access targeting low-income New York residents and set aside $12 million in escrow as a security pledge to meet all of its network expansion commitments going forward. The company now agrees it will complete its build out obligation in six increments of 21,646 customers through May 18, 2020. Charter will forfeit a portion of the $12 million each time it misses a deadline. The amount lost will depend on the percentage of the target missed and whether the company demonstrates it has completed necessary tasks to expand service. If the company manages to meet its deadlines going forward, it has the right to earn back some or all of its security pledge.

Charter has also agreed to develop a communications plan within 60 days of the settlement’s execution to inform New Yorkers whether they are part of the build-out plan.

The settlement offer will issued for public comment, and will require final Commission approval to take effect.
