Words such as “outlook,” “believe,” “expect,” “anticipate,” “estimate,” “intend,” “should,” “could,” “project,” and similar expressions, as well as statements in future tense, identify forward-looking statements. You should not consider forward-looking statements as a guarantee of future performance or results. Forward-looking statements are based on information available at the time those statements are made and/or management’s good faith belief at that time with respect to future events. Such statements are subject to risks and uncertainties that could cause actual performance or results to differ materially from those expressed in or suggested by the forward-looking statements. Important factors, assumptions, uncertainties, and risks that could cause such differences are discussed in our most recent Annual Report on Form 10-K, filed with the SEC on September 9, 2014 and our other filings with the Securities and Exchange Commission (“SEC”).

When you look at what we were eligible for, it was $283 million, about $133 million above what our frozen support level is today. And when you look at that, that's going to be something that we're going to take the vast majority. We're doing all the work on it. We'll do the final elections as we get a little bit further in the year.” Dan McCarthy, President & CEO , Frontier Communications – May 2015

11 Key Driver: Wireless Network Upgrades “from a capacity standpoint, that is why I have been saying consistently you will not see the Verizon Wireless capital program decrease anytime soon.

(a) Organic Revenue – Non-GAAP are revenues from businesses that are included for the full period in both the current and prior year quarter, excluding storm restoration services, if any. Organic Revenue growth is calculated as the percentage increase in revenues over those of the comparable prior year period (fiscal quarter) for revenues from businesses that are included in both periods for the full fiscal period, excluding revenues from storm restoration services, if any. (b) For comparisons of Organic Revenue beginning with Q3-14, Organic Revenue – Non-GAAP includes revenues of businesses acquired in Q2-13 (“Acquired Subsidiaries”) as the revenues from these businesses are included in both quarters (Q3-14 and Q3-13). (c) Organic revenues from customers for stimulus work is comprised of projects funded in part by the American Recovery and Reinvestment Act of 2009.

(a) Organic Revenue – Non-GAAP are revenues from businesses that are included for the full period in both the current and prior year presented, excluding storm restoration services, if any. Organic Revenue growth is calculated as the percentage increase in revenues over those of the comparable prior year period for revenues from businesses that are included in both periods for the full fiscal period, excluding revenues from storm restoration services, if any. (b) Non-GAAP adjustments in FY 2010 reflect adjustments in Q4-10 result from the Company’s 52/53 week fiscal year of $20.1 million. The Q4-10 Non-GAAP adjustments reflect the impact of the additional week in Q4-10 and are calculated by dividing contract revenues by 14 weeks. The result, representing one week of contract revenues, is subtracted from the GAAP-contract revenues to calculate 13 weeks of revenue for Q4-10 on a Non-GAAP basis for comparison purposes.

The above table presents a reconciliation of the Non-GAAP financial measure of Adjusted EBITDA for the periods specified to the most directly comparable GAAP measure. Adjusted EBITDA is a Non-GAAP financial measure within the meaning of Regulation G promulgated by the Securities and Exchange Commission. The Company defines Adjusted EBITDA - Non-GAAP as earnings before interest, taxes, depreciation and amortization, gain on sale of fixed assets, stock-based compensation expense, and certain non-recurring items. The Company believes this Non-GAAP financial measure provides information that is useful to the Company’s investors. The Company believes that this information is helpful in understanding period-over-period operating results separate and apart from items that may, or could, have a disproportionate positive or negative impact on the Company’s results of operations in any particular period. Additionally, the Company uses this Non-GAAP financial measure to evaluate its past performance and prospects for future performance. Adjusted EBITDA is not a recognized term under GAAP and does not purport to be an alternative to net income, operating cash flows, or a measure of earnings. Because all companies do not use identical calculations, this presentation of Non-GAAP financial measures may not be comparable to other similarly titled measures of other companies.
