Billing Dispute

11.  Billing Dispute

In early 2012, the Company received notification from an interexchange carrier disputing charges of approximately $3.0 million included in the Company’s intrastate tariffed billings that have been in place since 1998.  While the Company believes that its billings were correct and appropriate, it is currently in discussions with the carrier regarding a settlement of the dispute.
