Our operations are integrated into and reported as part of the consolidated segment data of CenturyLink. CenturyLink's chief operating decision maker ("CODM") is our CODM, but reviews our financial information on an aggregate basis only in connection with our quarterly and annual reports that we file with the Securities and Exchange Commission. Consequently, we do not provide our discrete financial information to the CODM on a regular basis. As such, we believe we have one reportable segment.

A relatively small number of customers account for a significant percentage of our revenue. Our top ten customers accounted for approximately 20% and 19% for the successor year ended December 31, 2018 and period ended December 31, 2017, and 18% and 16% for the predecessor period ended October 31, 2017 and for the predecessor year ended December 31, 2016, respectively.
