Commitments And Contingencies [Abstract]
Commitments And Contingencies	(15) Commitments and Contingencies: Although from time to time we make short-term purchasing commitments to vendors with respect to capital expenditures, we generally do not enter into firm, written contracts for such activities. In June 2015, Frontier accepted the Federal Communications Commission’s (FCC) offer of support to price cap carriers under the Connect America Fund (CAF) Phase II program, which is intended to provide long-term support for broadband in high cost unserved or underserved areas. This program provides $332 million in annual support, including $49 million in annual support related to the properties acquired in the Verizon Acquisition, through 2020 to make available 10 Mbps downstream/1 Mbps upstream broadband service to approximately 774,000 households across certain of the 29 states where we now operate. To the extent we do not enable the required number of households with 10 Mbps downstream/1 Mbps upstream broadband service by the end of the CAF Phase II term, we will be required to return a portion of the funds previously received. On April 28, 2016, the FCC completed its inquiry into whether certain terms and conditions contained in specifically identified special access tariff pricing plans offered by four carriers, including Frontier, are just and reasonable. The FCC held that certain of the tariff terms for business data TDM services, specifically DS1s and DS3s, were unreasonable. Specifically, the FCC struck down “excessive” early termination fees and “all-or-nothing” provisions. Frontier has revised its tariffs in accordance with the FCC’s Order. The FCC’s decision has no retroactive effect, and we anticipate no material impact to Frontier from it. The FCC deferred the issue of how its ruling will affect customers currently purchasing services from these tariffs to a Notice of Proposed Rulemaking. It is seeking comment on proposed changes to the way the FCC regulates traditional special access services and on a proposal to adopt pricing rules for Ethernet services in markets that are found to be “noncompetitive.” The potential impact to Frontier of this proceeding is unknown, though any pending initiative could adversely affect our operations or financial results. During the first nine months of 2016, we increased our outstanding performance letters of credit from $50 million at December 31, 2015 to $125 million as of September 30, 2016. We are party to various legal proceedings (including individual, class and putative class actions) arising in the normal course of our business covering a wide range of matters and types of claims including, but not limited to, general contracts, billing disputes, rights of access, taxes and surcharges, consumer protection, trademark and patent infringement, employment, regulatory, tort, claims of competitors and disputes with other carriers. In October 2013, the California Attorney General’s Office notified certain Verizon companies, including one of the subsidiaries that we acquired in the Verizon Acquisition, of potential violations of California state hazardous waste statutes primarily arising from the disposal of electronic components, batteries and aerosol cans at certain California facilities. We are cooperating with this investigation. While penalties relating to the alleged violations could exceed $100,000, we do not expect that any penalties ultimately incurred will be material. We accrue an expense for pending litigation when we determine that an unfavorable outcome is probable and the amount of the loss can be reasonably estimated. Legal defense costs are expensed as incurred. None of our existing accruals for pending matters, after considering insurance coverage, is material. We monitor our pending litigation for the purpose of adjusting our accruals and revising our disclosures accordingly, when required. Litigation is, however, subject to uncertainty, and the outcome of any particular matter is not predictable. We will vigorously defend our interests in pending litigation, and as of this date, we believe that the ultimate resolution of all such matters, after considering insurance coverage or other indemnities to which we are entitled, will not have a material adverse effect on our consolidated financial position, results of operations, or our cash flows.
