Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Pending Matters We are vigorously defending against all of the matters described below. As a matter of course, we are prepared to both litigate these matters to judgment, as well as to evaluate and consider all reasonable settlement opportunities. In this Note, when we refer to a class action as "putative" it is because a class has been alleged, but not certified in that matter. We have established accrued liabilities for these matters described below where losses are deemed probable and reasonably estimable. Switched Access Disputes Subsidiaries of CenturyLink, Inc., including us, are among hundreds of companies involved in an industry-wide dispute, raised in nearly 100 federal lawsuits (filed between 2014 and 2016) that have been consolidated in the United States District Court for the Northern District of Texas for pretrial procedures. The disputes relate to switched access charges that local exchange carriers ("LECs") collect from interexchange carriers ("IXCs") for IXCs' use of LEC's access services. In the lawsuits, IXCs, including Sprint Communications Company L.P. and various affiliates of Verizon Communications Inc., assert that federal and state laws bar LECs from collecting access charges when IXCs exchange certain types of calls between mobile and wireline devices that are routed through an IXC. Some of these IXCs have asserted claims seeking refunds of payments for access charges previously paid and relief from future access charges. In November 2015, the federal court agreed with the LECs and rejected the IXCs' contention that federal law prohibits these particular access charges. In light of this ruling, some of the defendants, including us, have petitioned the FCC to address these issues on an industry-wide basis. The outcome of these disputes and lawsuits, as well as any related regulatory proceedings that could ensue, are currently not predictable. If we are required to stop assessing these charges or to pay refunds of any such charges, our financial results could be negatively affected. Billing Practices Suits In June 2017, a former employee of CenturyLink filed an employment lawsuit against CenturyLink claiming that she was wrongfully terminated for alleging that CenturyLink charged some of its retail customers for products and services they did not authorize. Starting shortly thereafter and continuing since then, and based in part on the allegations made by the former employee, a series of consumer and shareholder putative class actions were filed against CenturyLink, and it received several shareholder derivative demands. In July 2017, the Minnesota Attorney General also filed a civil suit on behalf of the Minnesota consumers alleging that we and certain of our affiliates engaged in improper sales and billing practices. The filing of additional related lawsuits is possible. The consumer putative class actions have been transferred to the U.S. District Court for the District of Minnesota for coordinated and consolidated pretrial proceedings. The shareholder putative class actions have been consolidated into a single action that currently is pending in U.S. District Court for the Western District of Louisiana. In addition, a separate, related class action has been filed in U.S. District Court for the Southern District of New York purportedly on behalf of persons who purchased certain of CenturyLink's Senior Notes. Although CenturyLink and/or various of its subsidiaries are named in these lawsuits, Qwest Corporation is currently a named defendant in only the Minnesota Attorney General civil suit. In late June 2017, CenturyLink's Board of Directors formed a special committee of outside directors to investigate improper sales and billing practices and related matters. In August 2017, CenturyLink's Board of Directors formed a special litigation committee of outside directors to address the allegations of impropriety contained in the shareholder derivative demands. Both investigations are ongoing. Other Proceedings and Disputes From time to time, we are involved in other proceedings incidental to our business, including patent infringement allegations, administrative hearings or proceedings of state public utility commissions relating primarily to our rates or services, actions relating to employee claims, various tax issues, environmental law issues, grievance hearings before labor regulatory agencies and miscellaneous third party tort actions. We are currently defending several patent infringement lawsuits asserted against us by non-practicing entities, many of which are seeking substantial recoveries. These cases have progressed to various stages and one or more may go to trial in the coming 24 months if they are not otherwise resolved. Where applicable, we are seeking full or partial indemnification from our vendors and suppliers. As with all litigation, we are vigorously defending these actions and, as a matter of course, are prepared to litigate these matters to judgment, as well as to evaluate and consider all reasonable settlement opportunities. We are subject to various federal, state and local environmental protection and health and safety laws. From time to time, we are subject to judicial and administrative proceedings brought by various governmental authorities under these laws. Several such proceedings are currently pending, but none is reasonably expected to exceed $100,000 in fines and penalties. The outcome of these other proceedings is not predictable. However, based on current circumstances, we do not believe that the ultimate resolution of these other proceedings, after considering available defenses and any insurance coverage or indemnification rights, will have a material adverse effect on our financial position, results of operations or cash flows. CenturyLink, Inc. and its affiliates are involved in several legal proceedings to which we are not a party that, if resolved against them, could have a material adverse effect on their business and financial condition. As an indirect wholly-owned subsidiary of CenturyLink, Inc., our business and financial condition could be similarly affected. You can find descriptions of these legal proceedings in CenturyLink, Inc.'s quarterly and annual reports filed with the Securities and Exchange Commission. Because we are not a party to these, we have not accrued any liabilities for the matters. _________________ The ultimate outcome of the above-described matters may differ materially from the outcomes anticipated, estimated, projected or implied by us in certain of our forward-looking statements appearing above in this Note, and proceedings currently viewed as immaterial by us may ultimately materially impact us.
