While engaged in meetings with potential purchasers of Frontier’s new unsecured Senior Notes, Frontier commented that: (a) the Senior Notes will be subject to categories of covenants that are customary for high yield debt securities; (b) Frontier anticipates the potential to reduce the ratio of net debt to adjusted EBITDA to a ratio in the low 3’s over the long term, given the previously-disclosed potential to reduce leverage by between 0.1 and 0.2 times per year following closing (expected by end of first quarter 2016) of the previously announced transaction with Verizon Communications Inc., and (c) with respect to cash taxes, Frontier currently anticipates (i) cash taxes in 2016 could be in the range of $275 million to $325 million, inclusive of the anticipated closing of the Verizon Transaction, and (ii) if the bonus depreciation deduction allowance were to be extended for the 2015 tax year, Frontier currently estimates that the 2015 deferral impact would be approximately $80 million, with the benefit likely being realized through the reduction of cash tax payments in 2016.

The preceding information shall be deemed to be furnished, not filed, and shall not be incorporated by reference into any other filing with the Securities and Exchange Commission.

This document contains “forward-looking statements,” related to future, not past, events. Forward-looking statements address our expected future business and financial performance and financial condition, and contain words such as “expect,” “anticipate,” “intend,” “plan,” “believe,” “seek,” “see,” “will,” “would,” or “target.” Forward-looking statements by their nature address matters that are, to different degrees, uncertain. These risks and uncertainties include, but are not limited to: Frontier’s ability to complete the acquisition of Verizon’s California, Florida and Texas wireline operations, including the ability to complete the financing of the acquisition; the ability to successfully integrate the acquired operations into Frontier’s existing operations; the sufficiency of the assets to be acquired from Verizon to enable the combined company to operate the acquired business; the ability to enter into or obtain, or delays in entering into or obtaining, certain agreements and consents necessary to operate the acquired business as planned; the ability to obtain, delays in obtaining or adverse conditions contained in any required regulatory approvals for the Verizon transaction; and the other factors that are described in our filings with the U.S. Securities and Exchange Commission, including our reports on Forms 10-K and 10-Q. These risks and uncertainties may cause our actual future results to be materially different than those expressed in our forward-looking statements. We do not undertake to update or revise these forward-looking statements.
