According to NECA’s Washington Watch (September 19, 2016, issue), the National Tribal Telecommunications Association filed a letter on September 16, 2016, providing estimates on which carriers would be covered by NTTA’s proposal to waive or modify the operations expense limitation rule and which carriers would be eligible to receive tribal broadband factor support. It also included a complete summary of the TBF proposal, including details on how carrier-specific TBF support amounts and buildout obligations could be derived and estimated support amounts and obligations for eligible carriers. NTTA said the analysis shows 14 carriers would be eligible for the proposed waiver or modification of the OpEx limitation and an estimated 112 carriers would be eligible to elect the TBF support in exchange for the corresponding buildout obligations.
