Rate-of-return local exchange carriers have a very important decision to make in the next 41 days: move to Alternative Connect America Cost Model II support or continue to receive cost-based universal service fund support. They have until June 17, 2019 to decide. Even rate-of-return carriers that will receive less support under A-CAM II are considering the move. If they so choose, these “glide path” carriers will shift to A-CAM II support under a three-tiered transition process.
