NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)

(1)   Summary of Significant Accounting Policies:

(a)  Basis of Presentation and Use of Estimates:

Frontier Communications Corporation and its subsidiaries are referred to as “we,” “us,” “our,” “Frontier,” or the “Company” in this report. Our interim unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP) and should be read in conjunction with the consolidated financial statements and notes included in our Annual Report on Form 10-K for the year ended December 31, 2016. Certain reclassifications of amounts previously reported have been made to conform to the current presentation, as described in Note 2 – Recent Accounting Literature. All significant intercompany balances and transactions have been eliminated in consolidation. These interim unaudited consolidated financial statements include all adjustments (consisting of normal recurring accruals) considered necessary, in the opinion of Frontier’s management, to present fairly the results for the interim periods shown. Revenues, net loss and cash flows for any interim periods are not necessarily indicative of results that may be expected for the full year. For our interim financial statements as of and for the period ended September 30, 2017, we evaluated subsequent events and transactions for potential recognition or disclosure through the date that we filed this Form 10-Q with the Securities and Exchange Commission (SEC). 

Effective April 1, 2016, Frontier’s scope of operations and balance sheet changed materially as a result of the completion of the CTF Acquisition, as described in Note 3 – Acquisitions. Historical financial data presented for Frontier is not indicative of the future financial position or operating results for Frontier, and includes the results of the CTF Operations, as defined in Note 3 – Acquisitions, from the date of acquisition on April 1, 2016.

The preparation of our interim financial statements in conformity with GAAP requires management to make estimates and assumptions that affect (i) the reported amounts of assets and liabilities at the date of the financial statements, (ii) the disclosure of contingent assets and liabilities, and (iii) the reported amounts of revenue and expenses during the reporting period. Actual results may differ from those estimates. Estimates and judgments are used when accounting for the allowance for doubtful accounts, asset impairments, indefinite-lived intangibles, depreciation and amortization, income taxes, business combinations, and pension and other postretirement benefits, among others.

We operate in one reportable segment. Frontier provides both regulated and unregulated voice, data and video services to consumer, commercial and wholesale customers and is typically the incumbent voice services provider in its service areas.

On July 10, 2017, we effected a one for fifteen reverse stock split of our common stock. The reverse stock split reduced the number of common shares issued (which includes outstanding shares and treasury shares) from approximately 1,193,000,000 shares to 80,000,000 shares, and reduced shares outstanding from 1,178,000,000 shares to 79,000,000 shares. In addition, and at the same time, the total number of shares of common stock that Frontier is authorized to issue changed from 1,750,000,000 shares to 175,000,000 shares. There was no change in the par value of the common stock, and no fractional shares were issued. All share and per share amounts in the financial statements and footnotes have been retroactively adjusted for all periods presented to give effect to the reverse stock split. As a result of our reverse stock split the conversion rates of our Series A Preferred Stock were proportionately adjusted.

(b)  Revenue Recognition:

Revenue is recognized when services are provided or when products are delivered to customers. Revenue that is billed in advance includes monthly recurring network access services (including data services), special access services and monthly recurring voice, video and related charges. The unearned portion of these fees is initially deferred as a component of “Advanced billings” on our consolidated balance sheet and recognized as revenue over the period that the services are provided. Revenue that is billed in arrears includes non-recurring network access services (including data services), switched access services and non-recurring voice and video services. The earned but unbilled portion of these fees is recognized as

7

PART I. FINANCIAL INFORMATION (Continued)

FRONTIER COMMUNICATIONS CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)

revenue in our consolidated statements of operations and accrued in “Accounts receivable” on our consolidated balance sheet in the period that the services are provided. Excise taxes are recognized as a liability when billed. Installation fees and their related direct and incremental costs are initially deferred and recognized as revenue and expense over the average term of a customer relationship. We recognize as current period expense the portion of installation costs that exceeds installation fee revenue.

Frontier collects various taxes from its customers and subsequently remits these taxes to governmental authorities. Substantially all of these taxes are recorded through the consolidated balance sheet and presented on a net basis in our consolidated statements of operations. We also collect Universal Service Fund (USF) surcharges from customers (primarily federal USF) that we have recorded on a gross basis in our consolidated statements of operations and included within “Revenue” and “Network related expenses” of $52 million and $60 million, and $160 million and $161 million for the three and nine months ended September 30, 2017 and 2016, respectively.

In 2015, we accepted the FCC’s Connect America Fund (CAF) Phase II offer of support, which is a successor to and augments the USF frozen high cost support that we had been receiving pursuant to a 2011 FCC order. Upon completion of the CTF Acquisition, Frontier assumed the CAF Phase II support and related obligations that Verizon had previously accepted with regard to California and Texas. CAF Phase II funding is a program intended to subsidize the high cost of establishing and delivering communications services to certain unserved or underserved areas. We are recognizing these subsidies into revenue on a straight line basis, which is consistent with how the costs related to these subsidies are being and are expected to be incurred. CAF Phase II is a multi-year program which requires us to deploy broadband to a specified number of households in each of the states where funding was accepted. Failure to meet our deployment obligations at the end of the program in 2020 would result in a return of a portion of the funding received. We regularly evaluate our ability to meet our broadband deployment obligations and adjust revenue accordingly.

We categorize our products, services and other revenues among the following five categories:

· Data and Internet services include broadband services for consumer and commercial customers. We provide data transmission services to high volume commercial customers and other carriers with dedicated high capacity circuits (“nonswitched access”) including services to wireless providers (“wireless backhaul”);

· Voice services include traditional local and long distance wireline services, Voice over Internet Protocol (VoIP) services, as well as a number of unified messaging services offered to our consumer and commercial customers. Voice services also include the long distance voice origination and termination services that we provide to our commercial customers and other carriers;

· Video services include services provided directly to consumer customers through the FiOS® and Vantage video brands, and through DISH® satellite TV services;

· Other includes sales of customer premise equipment to our commercial customers and directory services, less our provision for bad debts; and

· Switched Access and Subsidy revenues include revenues derived from allowing other carriers to use our network to originate and/or terminate their local and long distance voice traffic (“switched access”). These services are primarily billed on a minutes-of-use basis applying tariffed rates filed with the FCC or state agencies. We also receive cost subsidies from state and federal authorities, including the Connect America Fund Phase II.

(c)Goodwill and Other Intangibles:

Goodwill represents the excess of purchase price over the fair value of identifiable tangible and intangible net assets acquired in a business combination. We have undertaken studies to determine the fair values of assets and liabilities acquired as well as to allocate the purchase price to assets and liabilities, including property, plant and equipment, goodwill and other identifiable intangibles. We examine the carrying value of our goodwill and trade name annually as of December 31, or more frequently as circumstances warrant, to determine whether there are any impairment losses. We test for goodwill impairment at the “operating segment” level, as that term is defined in GAAP.

We determined that we have one operating segment based on a number of factors that our management uses to evaluate and run our business operations, including similarities of customers, products and technology. We tested goodwill for impairment as of September30, 2017 as a result of the continued decline in share price of our common stock since June 30, 2017, the date of our last goodwill impairment test. Refer to Note 6 for a discussion of our goodwill impairment testing and results as of September 30, 2017. As stated in Note 2, we early adopted ASU No. 2017-04, “Simplifying the Test for Goodwill Impairment” during the second quarter of 2017 in conjunction with our goodwill impairment assessment.

Frontier amortizes finite-lived intangible assets over their estimated useful lives on the accelerated method of sum of the years digits. We review such intangible assets at least annually as of December 31 to assess whether any potential impairment exists and whether factors exist that would necessitate a change in useful life and a different amortization period.

(2)Recent Accounting Literature:

Recent Accounting Pronouncements Not Yet Adopted

Revenue Recognition

In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2014-09, “Revenue from Contracts with Customers.” This standard, along with its related amendments, requires companies to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which they expect to be entitled in exchange for those goods or services. This new standard will be adopted by Frontier for annual and interim reporting periods beginning with the first quarter of 2018.

The FASB allows two adoption methods under ASC 606. Companies are permitted to either apply the requirements retrospectively to all prior periods presented, or apply the requirements in the year of adoption, through a cumulative adjustment. We currently plan to adopt the standard in the first quarter of 2018, using the

9

PART I. FINANCIAL INFORMATION (Continued)

FRONTIER COMMUNICATIONS CORPORATION AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)

“modified retrospective method.” Under that method, we will apply the rules to all contracts existing as of January 1, 2018, recognizing, in beginning retained earnings, a cumulative-effect adjustment to include the establishment of contract asset and contract liability accounts with a corresponding adjustment to retained earnings. We will also provide additional disclosures comparing revenue recognized under ASC 606 to revenue as reported prior to the adoption of the standard.

Upon initial evaluation, we believe the key changes in the standard that impact our revenue recognition relate to the allocation of contract revenues among various services and equipment, and the timing of when those revenues are recognized. Additionally, the new standard will impact the timing of recognizing costs to obtain contracts. This includes a change in our existing policy related to the way we account for customer incentives, upfront non-recurring charges, commission payments, customer disputes and the allocation of discounts.

We are in the process of identifying and implementing changes to our systems, processes, policies and internal controls to meet the standard’s reporting and disclosure requirements.

Leases

In February 2016, the FASB issued ASU No. 2016 – 02, “Leases (Topic 842).” This standard establishes the principles to report transparent and economically neutral information about the assets and liabilities that arise from leases. Upon implementation, lessees will need to recognize almost all leases on their balance sheet as a right-of-use asset and a lease liability. It will be critical to identify leases embedded in a contract to avoid misstating the lessee’s balance sheet. For income statement purposes, the FASB retained a dual model, requiring leases to be classified as either operating or finance. Classification will be based on criteria that are largely similar to those applied in current lease accounting, but without explicit bright lines. Lessor accounting is similar to the current model, but updated to align with certain changes to the lessee model and the new revenue recognition standard. Existing sale-leaseback guidance, including guidance for real estate, is replaced with a new model applicable to both lessees and lessors. The new guidance is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years using modified retrospective application. Early application is permitted.  Frontier is in the initial stages of evaluating the potential impact this new standard may have on the consolidated financial statements.

Compensation – Retirement Benefits

In March 2017, the FASB issued ASU No. 2017-07, “Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost”. This standard was established to improve the presentation of net periodic pension cost and net periodic postretirement benefit cost by requiring that an employer disaggregate the service cost component of periodic benefit cost from the other components of net benefit cost. The amendments in the update also provide explicit guidance on how to present the service cost component and other components of net benefit cost in the income statement and allow only the service cost components of net benefit cost to be eligible for capitalization. The new guidance is effective for annual periods beginning after December 15, 2017, including interim periods within those annual periods and requires the presentation of the income statement to be applied retrospectively.  As a result of the standard, pension settlement costs and certain benefit costs which are currently included in operating expense, would be reported as other non-operating expense and will no longer be capitalized.  This will have a material impact on previously reported operating income and may have a material impact to operating income in future periods, however, the impact to pre-tax income is not expected to be material.

Recently Adopted Accounting Pronouncements

Share-Based Payments - Scope of Modification Accounting

In May 2017, the FASB issued ASU No. 2017-09, Scope of Modification Accounting which amends the scope of modification accounting for share-based payment arrangements. This standard provides guidance on the types of changes to the terms or conditions of share-based payment awards to which an entity would be required to apply modification accounting under ASC 718. Specifically, an entity would not apply modification accounting if the fair value, vesting conditions, and classification of the awards are the same immediately before and after the modification. The new guidance is effective for annual periods beginning after December 15, 2017, including interim periods within those annual periods and early adoption is permitted including in any interim period. Frontier has adopted this standard during the second quarter 2017, with no impact to our share-based payment awards.

Intangibles – Goodwill

In January 2017, the FASB issued ASU No. 2017-04, “Simplifying the Test for Goodwill Impairment.” This standard was established to simplify how an entity is required to test goodwill for impairment by eliminating Step 2from the goodwill impairment test. Step 2 measures a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of that goodwill. Under the amendments in this Update, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. Additionally, an entity should consider income tax effects from any tax deductible goodwill on the carrying amount of the reporting unit when measuring the goodwill impairment loss, if applicable. The FASB also eliminated the requirements for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment and, if it fails that qualitative test, to perform Step 2 of the goodwill impairment test. Therefore, the same impairment assessment applies to all reporting units. An entity is required to disclose the amount of goodwill allocated to each reporting unit with a zero or negative carrying amount of net assets. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. Frontier early adopted this standard during the second quarter of 2017 in conjunction with our goodwill impairment assessment. See Note 1 and Note 6 for further discussion.

Compensation – Stock Compensation

In March 2016, the FASB issued ASU No. 2016-09, “Improvements to Employee Share-Based Payment Accounting,” to amend ASC Topic 718, “Compensation – Stock Compensation.” The ASU is part of the FASB’s ongoing simplification initiative, which is designed to reduce cost and complexity while maintaining or improving the usefulness of the information provided to the users of financial statements. The simplifications address a variety of areas for public entities, including the following: 1) accounting for income taxes, 2) classification of excess tax benefits on the statement of cash flows, 3) forfeitures, 4) minimum statutory tax withholding requirements, 5) classifications of employee taxes paid on the statement of cash flows when an employer withholds shares for tax withholding purposes, and 6) classification of awards with repurchase features. This guidance was effective for Frontier as of the third quarter of 2017.  During the nine months ended September 30, 2017, Frontier recognized $2millionof income tax expense and recorded a cumulative effect adjustment to beginning accumulated deficit of $1 million to recognize all unrecognized deferred tax benefits recorded as of January 1, 2017. For the nine months ended September 30, 2016, Frontier reclassified $10 million of taxes paid on behalf of employees related to shares withheld from “Cash flows provided from (used by) operations” to “Cash flows used by financing activities” in accordance with the new standard.

(3)  Acquisitions:

The CTF Acquisition

On April 1, 2016, Frontier acquired the wireline operations of Verizon Communications, Inc. in California, Texas and Florida (the CTF Operations) for a purchase price of $10,540 million in cash and assumed debt (the CTF Acquisition), pursuant to the February 5, 2015 Securities Purchase Agreement, as amended. The final allocation of the purchase price presented below represents the effect of recording the fair value of assets acquired and liabilities assumed as of the date of the CTF Acquisition, based on the total transaction cash consideration of $9,871 million.

($ in millions)
Current assets	$	353
Property, plant & equipment		6,096
Goodwill		2,606
Other intangibles - primarily customer list		2,262
Current liabilities		(579)
Long-term debt		(544)
Other liabilities		(323)
Total net assets acquired	$	9,871

The fair value estimates related to the allocation of the purchase price to Other intangibles were revised and updated during the first quarter of 2017 from the previous estimates as of December 31, 2016. The allocation that was reported as of December 31, 2016 for Other intangibles increased $100 million, from $2,162 million to $2,262 million. These measurement period adjustments resulted in$20 million of amortization expense during the first quarter of 2017 that would have been recorded in 2016 if the adjustments had been recognized as of the acquisition date.Other adjustments to the allocation of the purchase price for the CTF Acquisition during the first quarter of 2017 resulted in a $140million decrease in Property, plant & equipment, a $61million increase in Current liabilities, and a $98million increase in Goodwill.

The total consideration exceeded the net estimated fair value of the assets acquired and liabilities assumed by $2,606million, which we recognized as goodwill. This goodwill is attributable to strategic benefits, including enhanced financial and operational scale, market diversification and leveraged combined networks that we expect to realize. This amount of goodwill associated with the CTF Acquisition will be deductible for income tax purposes.

In 2017, we sold certain properties,  generating $102  million in net proceeds, of which $97 million relates to property subject to leasebacks.  For these properties, we have deferred$66 million in related gains that will be amortized over the related lease terms of two years. For the nine months ended September 30, 2017, amortization of these deferred gains totaled$14 million, which areincluded in “Selling, general and administrative expenses” on our consolidated income statement. We have remaining deferred gain balances of $52  million,  which are included in “Other liabilities”.

(6)  Goodwill and Other Intangibles:  

The activity in goodwill from January 1, 2017 to September 30, 2017 was as follows:

($ in millions)
Balance at January 1, 2017	$	9,674
CTF Acquisition adjustments		98
Impairment		(670)
Balance at September 30, 2017	$	9,102

We are required to perform impairment tests related to our goodwill annually, which we perform as of December 31, or sooner if an indicator of impairment occurs. Due to the continued decline inour stock price we had triggering events in each of the three quarters in 2017.

We use a market multiples approach to determine fair value. Marketplace company comparisons and analyst reports within the telecommunications industry have historically supported a range of fair values of multiples between 5.0x and 7.9x annualized EBITDA (defined as operating income, net of acquisition and integration costs, pension/OPEB expense, pension settlement costs, stock-based compensation expense,  goodwill impairment, storm-related costs, and restructuring costs and other charges, as well as depreciation and amortization). We estimated the enterprise fair value using a multiple of 5.8x EBITDA.

Our second quarter quantitative assessment indicated that the carrying value of the enterprise exceeded its fair value and, therefore, an impairment existed, principally due to the decline in our profitability during the second quarter of 2017. We elected to early adopt the simplified goodwill method under ASU 2017-04, and recorded our goodwill impairment based on the amount that the enterprise carrying value exceeded the fair value, which resulted in a goodwill impairment of $670 million. 

Our first and third quarter quantitative assessments indicated that the fair value of the enterprise exceeded its carrying value and, therefore, no indication of impairment existed in either period.

The market multiples approach that we use incorporates significant estimates and assumptions related to the forecasted results for the remainder of the year including revenues, expenses, and the achievement of other cost synergies.Our assessment includes many qualitative factors that require significant judgment. Alternative interpretations of these factors could have resulted in different conclusions regarding the need for, or size of, an impairment. Continued declines in our profitability or cash flows or in the sustained, historically low trading prices of our common stock may result in further impairment.

We also considered whether the carrying values of finite-lived intangible assets and property plant and equipment may not be recoverable or whether the carrying value of certain indefinite-lived intangible assets were impaired, noting no additional impairment was present as of September30, 2017.

In September 2017, Frontier used proceeds from Term Loan B (see definition and note discussion below)to retire $24 million of 8.500% Notes due 2020, $10 million of 9.250% Notes due 2021, $6 million of 7.125% Notes due 2019, and $5 million of 8.125% Notes due 2018.  Frontier recorded a gain of $1 million driven primarily by discounts on the retirement of the notes. On April 17, 2017, Frontier used cash available on hand to retire $210 million of 8.25% Senior Notes that matured on such date.

In June 2017, Frontier used cash proceeds from Term Loan B (see definition and note discussion below) to retire $763 million of 8.875% Notes due 2020 and $527 million of 8.500% Notes due 2020. Frontier recorded a loss on early extinguishment of debt of $90 million driven by premiums paid to retire the notes and unamortized original issuance costs.

On February 27, 2017, Frontier entered into a first amended and restated credit agreement with JPMorgan Chase Bank, N.A., as administrative agent, and the lenders party thereto, pursuant to which Frontier combined its revolving credit agreement, dated as of June 2, 2014, and its term loan credit agreement, dated as of August 12, 2015. Under the JPM Credit Agreement, as further amended on June 15, 2017 by Increase Joinder No.1 (as so amended, the JPM Credit Agreement), Frontier has a $1,625 million senior secured term loan A facility (the Term Loan A) maturing on March 31, 2021, an $850 million undrawn secured revolving credit facility maturing on February 27, 2022 (the Revolver), and $1,500 million senior secured term loan B facility (the Term Loan B) maturing on June 15, 2024.  The maturities of the Term Loan A, the Revolver, and the Term Loan B, in each case if still outstanding, will be accelerated in the following circumstances: (i) if, 91 days before the maturity date of any series of Senior Notes maturing in 2020, 2023 and 2024, more than $500 million in principal amount remains outstanding on such series; or (ii) if, 91 days before the maturity date of the first series of Senior Notes maturing in 2021 or 2022, more than $500 million in principal amount remains outstanding, in the aggregate, on the two series of Senior Notes maturing in such year. The determination of interest rates for each of the facilities under the JPM Credit Agreement is based on margins over the Base Rate (as defined in the JPM Credit Agreement) or over LIBOR, at the election of Frontier. Interest rate margins on the Term Loan A and Revolver (ranging from 0.75% to 1.75% for Base Rate borrowings and 1.75% to 2.75% for LIBOR borrowings) are subject to adjustment based on Frontier’s Total Leverage Ratio (as defined in the JPM Credit Agreement). The interest rate on the Term Loan A as of September 30, 2017 was LIBOR plus 2.75%. Interest rate margins on the Term Loan B (2.75% for Base Rate borrowings and 3.75% for LIBOR borrowings) are not subject to adjustment. The security package under the JPM Credit Agreement includes pledges of the equity interests in certain Frontier subsidiaries and guaranties by certain Frontier subsidiaries. As of September 30, 2017, the revolving credit facility was fully available and no borrowings had been made thereunder. The revolving credit facility is available for general corporate purposes but may not be used to fund dividend payments.

Frontier has two senior secured credit agreements with CoBank, ACB, as administrative agent, lead arranger and a lender, and the other lenders party thereto: the first, for a $350 million senior term loan facility drawn in 2014 (the 2014 CoBank Credit Agreement), matures on October 24, 2019, and the second, for a $315 million senior term loan facility drawn in October 2016 (the 2016 CoBank Credit Agreement), matures on October 12, 2021. We refer to the 2014 CoBank Credit Agreement and the 2016 CoBank Credit Agreement collectively as the CoBank Credit Agreements.

Repayment of the outstanding principal balance under each of the CoBank Credit Agreements is being made in quarterly installments ($9 million, with respect to the 2014 CoBank Credit Agreement, and $8 million, with respect to the 2016 CoBank Credit Agreement), in each case with the remaining outstanding principal balance to be repaid on the applicable maturity date. Borrowings under each of the CoBank Credit Agreements bear interest based on the margins over the Base Rate (as defined in the applicable CoBank Credit Agreement) or over LIBOR, at the election of Frontier.

On March 29, 2017, Frontier amended the 2014 and 2016 CoBank Credit Agreements. The amendments provide that interest rate margins under each of these facilities will range from 0.875% to 3.875% for Base Rate borrowings and 1.875% to 4.875% for LIBOR borrowings, subject to adjustment based on our Total Leverage Ratio, as defined in each credit agreement. The interest rate on each of the facilities as of September 30, 2017 was LIBOR plus 3.875%. In addition, the amendments provide for increases in the maximum Leverage Ratio and expansion of the security package identical to those contained in the JPM Credit Agreement.

In calculating diluted net loss per common share for the three and ninemonths ended September 30, 2016, the effect of all common stock equivalents is excluded from the computation as the effect would be antidilutive.

Stock Options

For the three and ninemonths ended September30, 2017 and 2016, previously granted options to purchase 2,664 shares, issuable under employee compensation plans were excluded from the computation of diluted earnings (loss) per share (EPS) for those periods because the exercise prices were greater than the average market price of our common stock and, therefore, the effect would be antidilutive.

Stock Units

At September 30, 2017 and 2016, we had 161,020 and 116,223 stock units, respectively, issued under the Non-Employee Directors’ Deferred Fee Equity Plan (Deferred Fee Plan), the Non-Employee Directors’ Equity Incentive Plan (Directors’ Equity Plan),  the 2013 Equity Incentive Plan and the 2017 Equity Incentive Plan. These securities have not been included in the diluted EPS calculation for the three months ended September 30, 2017 and 2016 and the nine months ended September 30, 2016 because their inclusion would have an antidilutive effect. Compensation costs associated with the issuance of stock unitswere ($4)million for the nine months ended September 30, 2017. There were no compensation costs associated with the issuance of stock units for the nine months ended September 30, 2016.

Mandatory Convertible Preferred Stock

The impact of the common share equivalents associated with approximately 19,250,000 shares of Series A Preferred stock were not included in the diluted EPS calculation as of September 30, 2017 and 2016, as their impact was antidilutive.

(12)Stock Plans:

All share and per share amounts in the tables below have been retroactively adjusted for all periods presented to give effect to the reverse stock split. See Note 1 – Summary of Significant Accounting Policies for additional details.

At September 30, 2017, we had seven stock-based compensation plans under which grants were made and awards remained outstanding. No further awards may be granted under six of the plans: the 1996 Equity Incentive Plan (the 1996 EIP), the Amended and Restated 2000 Equity Incentive Plan (the 2000 EIP), the 2009 Equity Incentive Plan (the 2009 EIP), the 2013 Equity Incentive Plan (the 2013 EIP), the Deferred Fee Plan and the Directors’ Equity Plan. At September 30, 2017, there were approximately 5,667,000shares authorized for grant and approximately 4,381,000 shares available for grant under the 2017 Equity Incentive Plan (the 2017 EIP and together with the 1996 EIP, the 2000 EIP,  the 2009 EIP and the 2013 EIPS, the EIPs). Our general policy is to issue treasury shares upon the grant of restricted shares and the exercise of options.

Performance Shares

On February 16, 2017, the Compensation Committee of our Boardof Directors granted approximately 157,400performance shares under the Frontier Long Term Incentive Plan (the LTIP) and set the operating cash flow performance goal for 2017, which applies to the first year in the 2017-2019 measurement period, the second year of the 2016-2018 measurement period and the third year of the 2015-2017 measurement period.

The following summary presents information regarding LTIP target performance shares as of September 30, 2017 and changes during the nine months then ended with regard to LTIP shares awarded under the 2013 EIP and the 2017 EIP:

	Number of
	Shares
	(in thousands)
Balance at January 1, 2017	190
LTIP target performance shares granted, net	211
LTIP target performance shares earned	(41)
LTIP target performance shares forfeited	(51)
Balance at September 30, 2017	309

For purposes of determining compensation expense, the fair value of each performance share is measured at the end of each reporting period and, therefore, will fluctuate based on the price of Frontier common stock as well as performance relative to the targets. For the nine months ended September 30, 2017 and 2016, we recognized net compensation expense, reflected in “Selling, general and administrative expenses,” of $0  and $4million, respectively, for the LTIP.

Restricted Stock

The following summary presents information regarding unvested restricted stock as of September 30, 2017 and changes during the ninemonths then ended with regard to restricted stock granted under the 2013 EIP and the 2017 EIP:

		Weighted
		Average
	Number of	Grant Date		Aggregate

Restricted stock forfeited	(119)	$	61.21
Balance at September 30, 2017	664	$	59.64	$	8

For purposes of determining compensation expense, the fair value of each restricted stock grant is estimated based on the average of the high and low market price of a share of our common stock on the date of grant, for shares granted prior to May 10, 2017. Beginning on May 10, 2017, the fair value of each restricted stock grant is estimated based on the closing price of a share of our common stock on the date of the grant. Total remaining unrecognizedcompensation cost associated with unvested restricted stock awards that is deferred at September 30, 2017 was $26million, and the weighted average vesting period over which this cost is expected to be recognized is approximately 1.5 years.

Shares of restricted stock granted during the first nine months of 2016 totaled 375,133. The total fair value of shares of restricted stock granted and vested at September 30, 2016 was approximately $23  million and $15  million, respectively. The total fair value of unvested restricted stock at September 30, 2016 was $37  million. The weighted average grant date fair value of restricted shares granted during the nine months ended September 30, 2016 was $78.60 per share.

We have granted restricted stock awards to employees in the form of our common stock. None of the restricted stock awards may be sold, assigned, pledged or otherwise transferred, voluntarily or involuntarily, by the employees until the restrictions lapse, subject to limited exceptions. The restrictions are time-based. Compensation expense, recognized in “Selling, general and administrative expenses,” of $14million for each of the nine month periods ended September 30, 2017 and 2016, has been recorded in connection with these grants.

As a result of the pension settlement accounting discussed in Note 14, the Frontier Communications Pension Plan (the Pension Plan) was remeasured as of September30, 2017. This remeasurement resulted in a decrease in the discount rate from 4.10% at March 31, 2017 to 3.8% at June 30, 2017 and September 30, 2017, in addition to census data changes resulting in the recording of a loss on remeasurement to Other comprehensive income (loss) during each of the quarters. For the nine months ended September 30, 2017, Frontier recorded a net loss on remeasurement of $32 million, to Other comprehensive income (loss).  Additionally, Frontier recorded pension settlement charges  totaling $77million  ($48million net of tax) to Other comprehensive income (loss). Refer to Note 14 for details about the settlement accounting.

During the first nine months of 2017 and 2016, we capitalized $20  million and $18 million, respectively, of pension and OPEB expense into the cost of our capital expenditures, as the costs relate to our engineering and plant construction activities.

ThePension Plan contains provisions that provide certain employees with the option of receiving a  lump sum payment upon retirement. Frontier’s accounting policy is to record these payments as a settlement only if, in the aggregate, they exceed the sum of the annual service and interest costs for the Pension Plan’s net periodic pension benefit cost. During the three and nine months ended September 30, 2017, lump sum pension settlement payments to terminated or retired individuals amounted to $87 million and $449 million, which exceeded the settlement threshold of $224 million, and as a result, Frontier recognized non-cash settlement charges totaling$77 million during the first nine months of 2017. The non-cash charge accelerated the recognition of a portion of the previously unrecognized actuarial losses in the Pension Plan. These non-cash chargesincreased our recorded net loss and accumulated deficit, with an offset to accumulated other comprehensive loss in shareholders’ equity. An additional pension settlement charge will be required in the fourth quarter of 2017, the amount of which will be dependent on the lump sum benefit payments made during the fourth quarter. As a result of the recognition of the settlement charges in the first nine months of 2017, the net pension plan liability was remeasured as ofSeptember 30, 2017, June 30, 2017 and March 31, 2017 to be $717 million, $711 million and $665million, respectively, as compared to the $699 million measured and recorded at December 31, 2016. The remeasured funded status of the Pension Plan wasapproximately 80%, as of September 30, 2017, similar to December 31, 2016. Frontier did not record any adjustment to the pension plan liability, beyond the settlement charge, as a result of this remeasurement.

Our Pension Plan assets decreased from $2,766 million at December 31, 2016 to $2,604  million at September 30, 2017, a decrease of $162million, or  6%. This decrease was a result of benefit payments of $492 million, partially offset by positive investment returns of $270 million, net of investment management and administrative fees, and contributions in excess of the Differential (as defined below) of $60  million,during the first nine months of 2017.  

As part of the CTF Acquisition, Verizon was required to make a cash payment to Frontier for the difference in assets initially transferred by Verizon into the Pension Plan and the related obligation (the Differential).  In the third quarter of 2017,we received the $131 million Differential payment from Verizon, and have remitted an equivalent amount to the  Pension Plan as of September 30, 2017. As the Differential was reflected as a receivable of the Pension Plan at December 31, 2016, the cash funding had no impact to plan assets.

(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 $332million in annual support, including $49million in annual support related to the properties acquired in the CTF 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 would be required to return a portion of the funds previously received.

On April 20, 2017, the FCC issued an Order that will significantly alter how Commercial Data Services are regulated once the rules go into effect. Specifically, the Order adopted a test to determine, on a county-by-county basis, whether price cap ILECs’, like Frontier’s, DS1 and DS3 services will continue to be regulated. The test is likely to result in deregulation in a substantial number of our markets. Once implemented, the deregulation will allow Frontier to offer its DS1 and DS3 services in a manner that better responds to the competitive marketplace and allows for commercial negotiation. The areas that remain regulated may be subject to price fluctuations depending upon the price cap formula that year. Multiple parties have appealed and requested a stay of this Order. Frontier cannot predict the extent to which these regulatory changes will result in changes to revenues at this time. 

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, shareholder, regulatory, tort, claims of competitors and disputes with other carriers. 

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.

In October 2013, the California Attorney General’s Office notified certain Verizon companies, including one of the subsidiaries that we acquired in the CTF 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. We have accrued an amount for potential penalties

that we deem to be probable and reasonably estimated, and we do not expect that any potential penalties, if ultimately incurred, will be material in comparison to the established accrual.

Item 2.  Management’s Discussion and Analysis of Financial Condition and Results of Operations

Forward-Looking Statements

This Quarterly Report on Form 10-Q 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. For us, particular uncertainties that could cause our actual results to be materially different than those expressed in our forward-looking statements include:

· competition from cable, wireless and wireline carriers, satellite, and OTT companies, and the risk that we will not respond on a timely or profitable basis;

· our ability to successfully adjust to changes in the communications industry, including the effects of technological changes and competition on our capital expenditures, products and service offerings;

· risks related to the operation of properties acquired from Verizon, including our ability to retain or obtain customers in those markets, our ability to realize anticipated cost savings, and our ability to meet commitments made in connection with the acquisition;

· reductions in revenue from our voice customers that we cannot offset with increases in revenue from broadband and video subscribers and sales of other products and services;

· our ability to maintain relationships with customers, employees or suppliers;

· our ability to attract/retain key talent;

· the impact of regulation and regulatory, investigative and legal proceedings and legal compliance risks;

· continued reductions in switched access revenues as a result of regulation, competition or technology substitutions;

· the effects of changes in the availability of federal and state universal service funding or other subsidies to us and our competitors;

· our ability to effectively manage service quality in our territories and meet mandated service quality metrics;

· our ability to successfully introduce new product offerings;

· the effects of changes in accounting policies or practices, including potential future impairment charges with respect to our intangible assets;

· our ability to effectively manage our operations, operating expenses, capital expenditures, debt service requirements and cash paid for income taxes and liquidity, which may affect payment of dividends on our common and preferred shares;

· the effects of changes in both general and local economic conditions on the markets that we serve;

· the effects of increased medical expenses and pension and postemployment expenses;

· the effects of changes in income tax rates, tax laws, regulations or rulings, or federal or state tax assessments;

· our ability to successfully renegotiate union contracts;

30

PART I. FINANCIAL INFORMATION (Continued)

FRONTIER COMMUNICATIONS CORPORATION AND SUBSIDIARIES

· changes in pension plan assumptions, interest rates, regulatory rules and/or the value of our pension plan assets, which could require us to make increased contributions to the pension plan in 2017 and beyond;

· adverse changes in the credit markets;

· adverse changes in the ratings given to our debt securities by nationally accredited ratings organizations;

· the availability and cost of financing in the credit markets;

· covenants in our indentures and credit agreements that may limit our operational and financial flexibility;

· the effects of state regulatory cash management practices that could limit our ability to transfer cash among our subsidiaries or dividend funds up to the parent company;

· the effects of severe weather events or other natural or man-made disasters, which may increase our operating expenses or adversely impact customer revenue;

· the impact of potential information technology or data security breaches or other disruptions; and

· the risks and other factors contained in our other filings with the U.S. Securities and Exchange Commission, including our reports on Form 10-K.

Any of the foregoing events, or other events, could cause ourresults to vary from management’s forward-looking statements included in this report. You should consider these important factors in evaluating any statement in this report or otherwise made by us or on our behalf. The following information is unaudited and should be read in conjunction with the consolidated financial statements and related notes included in this report. We have no obligation to update or revise these forward-looking statements and do not undertake to do so.

Investors should also be aware that while we do, at various times, communicate with securities analysts, it is against our policy to disclose to them selectively any material non-public information or other confidential information. Accordingly, investors should not assume that we agree with any statement or report issued by an analyst irrespective of the content of the statement or report.

Management’s Discussion and Analysis

On April 1, 2016, we completed our acquisition of Verizon’s wireline properties in California, Texas, and Florida (the CTF Acquisition, of the CTF Operations).Frontier’s scope of operations and balance sheet changed materially as a result of the completion of the CTF Acquisition. Historical financial and operating data presented for Frontier includes the results of the CTF Operations that were acquired in the CTF Acquisition from the date of acquisition on April 1, 2016 and is not indicative of future operating results. The financial discussion below includes a comparative analysis of our results of operations on a historical basis as of and for the nine months ended September 30, 2017 and 2016.

On July 10, 2017, we effected a one for fifteen reverse stock split of our common stock. The reverse stock split reduced the number of common shares issued (which includes outstanding shares and treasury shares) from approximately 1,193,000,000 shares to 80,000,000 shares, and reduced shares outstanding from 1,178,000,000 shares to 79,000,000 shares. In addition, and at the same time, the total number of shares of common stock that Frontier is authorized to issue changed from 1,750,000,000 shares to 175,000,000 shares. There was no change in the par value of the common stock, and no fractional shares were issued. All share and per share amounts in the financial discussion below have been retroactively adjusted for all periods presented to give effect to the reverse stock split. As a result of our reverse stock split the conversion rates of our Series A Preferred Stock were proportionately adjusted.

Our financial results for the first nine months of 2017 include the CTF Operations for the first quarter of 2017. With the acquisition occurring April 1, 2016, there are no comparative results for the corresponding period in 2016. The table below reflects the results of operations for the CTF Operations for the first quarter of 2017. In the narrative that follows for the nine month period, unless otherwise noted we will only discuss the remaining variance.

The sections below include tables that present customer counts, average monthly consumer revenue per customer (ARPC) and consumer customer churn which we define as the average of the number of consumer customer deactivations during the month divided by the number of consumer customers at the beginning of the month.

Management believes that consumer customer counts and average monthly revenue per customer are important factors in evaluating our consumer customer trends. Among the key services we provide to consumer customers are voice service, data service and video service. We continue to explore the potential to provide additional services to our customer base, with the objective of meeting all of our customers’ communications needs.

The following should be read in conjunction with Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations” included in our Annual Report on Form 10-K for the year ended December 31, 2016.

Customer Trends and Revenue Performance

We provide service and product options in our consumer and commercial offerings in each of our markets. As of September 30, 2017, 68% of our consumer broadband customers were subscribed to at least one other service offering.

We had approximately 4,486,000 and 5,035,000total consumer customers as of September 30, 2017 and 2016, respectively. Our consumer customer churn was 2.08% for the three months ended September 30, 2017 (1.92% for Frontier legacy and 2.33% for CTF Operations) compared to 2.08%  (1.89% for Frontier legacy and 2.34% for CTF Operations) for the third quarter of 2016 and 2.24% (1.95% for Frontier legacy and 2.69% for CTF Operations) for the second quarter of 2017, respectively. The consolidated average monthly consumer revenue per customer

(consumer ARPC) decreased by $1.43 or 2% to $80.91 during the third quarter of 2017 compared to the prior year period. The overall decrease in consumer ARPC is a result of lower voice services revenue and lower video revenue from our CTF Operations, partially offset by higher Frontier Secure revenue.

Our consumer customer churn was 2.23% for the nine months ended September 30, 2017 (1.94% for Frontier legacy and 2.68% for CTF Operations) compared to 1.94% (1.81% for Frontier legacy and 2.27% for CTF Operations) for the nine months ended September 30, 2016. The consolidated average monthly consumer revenue per customer (consumer ARPC) increased by $4.62 or 6% to $80.73 during the first nine months of 2017 compared to the prior year period. The overall increase in consumer ARPC is a result of higher revenue due to having nine months of CTF Operations in 2017 and only six months in 2016, partially offset by lower voice services revenue.

We had approximately 463,000 and 516,000 total commercial customers as of September 30, 2017 and 2016, respectively. We lost approximately 10,000 commercial customers during the three months ended September 30, 2017 compared to a loss of 12,000 customers for the three months ended September 30, 2016 and a loss of 11,000 for the three months ended June 30, 2017. Frontier expects the declines in voice services revenue and wireless backhaul revenues from commercial customers to continue for the remainder of 2017. Our Ethernet product revenues from our SME (small business, medium business and larger enterprise customers) and carrier customers have grown by 9% for the Frontier legacy operations during the third quarter of 2017, compared to the prior year period, and declined by 3% (including CTF Operations) compared to the second quarter of 2017.

We had approximately 4,000,000 and 4,362,000 broadband subscribers as of September 30, 2017 and 2016, respectively. During the three months ended September 30, 2017, we lost approximately 63,000 net broadband subscribers compared to a loss of 99,000 and a loss of 99,000 for the three months ended September 30, 2016 and June 30, 2017, respectively. 

We offer video services under the Vantage brand to certain of our customers in portions of Connecticut, North Carolina, South Carolina and Minnesota, and under the FiOS® brand in portions of California, Texas, and Florida (and on a limited basis in Indiana, Oregon and Washington). We also offer satellite TV video service to our customers under an agency relationship with DISH® in all of our markets.  For the three months ended September 30, 2017, we lost approximately 36,000 netvideo subscribers across all markets. At September 30, 2017, we had 981,000 linear video subscribers that are served with FiOS or Vantage video service. In addition to our linear video subscribers, we have approximately 244,000 DISH satellite video customers.

Revenue

We generate revenues primarily through either a monthly recurring fee or a fee based on usage, and revenue recognition is not dependent upon significant judgments by management, with the exception of a determination of the provision for uncollectible amounts.

Consolidated total revenue for the nine months ended September 30, 2017 increased $424 million to $6,911 million as compared to the prior year period. Excluding additional revenue from the CTF Operationsfor the first quarter of 2017, our revenue for the first nine months of 2017 decreased $663million, or 10%, as compared to the prior year period. This decline in 2017 is primarily the result of decreases in voice services revenues, lower switched and nonswitched access revenue, video, and data services revenue, each as described in more detail below.

Customer revenue for the nine months ended September 30, 2017 increased $436 million to $6,325 million as compared to the prior year period. Excluding additional revenue from the CTF Operationsfor the first quarter of 2017, our customer revenue for the first nine months of 2017 decreased $599 million, or 10%, as compared to the prior year period.

Consolidated consumer customer revenue for the nine months ended September 30, 2017 increased $203 million, or 6%, as compared to the prior year period.  Excluding additional consumer customer revenue from the CTF Operationsfor the first quarter of 2017,  revenues for the first nine months of 2017 decreased $411 million, or 13%, compared to the prior year period, primarily as a result of decreases in voice, video and data services revenue. Similar to other wireline providers, we have experienced declines in the number of traditional voice customers and switched access minutes of use as a result of competition and the availability of substitutes, a trend we expect to continue.

Consolidated commercial customer revenue for the nine months ended September 30, 2017 increased $233 million, or 9%, as compared to the prior year period. Excluding additional commercial customer revenue from the CTF Operationsfor the first quarter of 2017,  revenues for 2017 declined $188 million, or 7%, as compared to the prior year period, principally as a result of decreases in our voice services revenue and nonswitched revenue including wireless backhaul revenue.

Consolidated switched access and subsidy revenue of $586 million represented 8% of our revenues for the nine months ended September 30, 2017. Switched access revenue was $129 million for both the first nine months of 2017 and 2016, or 2% of our revenues for each period. The Report and Order released by the FCC on November 18, 2011 (the 2011 Order) provided for the gradual elimination of terminating traffic charges by 2017 with a related decline in operating expenses. Switched access revenue declined sequentially in the third quarter of 2017, reflecting the rate reductions mandated by the 2011 Order, and we anticipate that we have experienced nearly all of the rate decline related to the 2011 Order. We have been able to recover a significant portion of these lost revenues through end user rates and other replacement support mechanisms, a trend we expect will continue throughout 2017. We expect declining revenue trends due to reduced volume in switched access revenue to continue in the fourth quarter of 2017 in our legacy operations. Subsidy revenue, including CAF Phase II subsidies, was $457 million for the nine months ended September 30, 2017, or 7% of our revenues, which decreased from $468 million, or 7% of our revenues, in the prior year period.  

We categorize our products, services, and other revenues into the following five categories:

Data and Internet Services

Data and internet services include broadband services for consumer and commercial customers. We provide data transmission services to high volume commercial customers and other carriers with dedicated high capacity circuits (“nonswitched access”) including services to wireless providers (“wireless backhaul”).

Data and Internet services revenue for the three months ended September 30, 2017 decreased $89 million as compared with 2016. Data services revenue for the three months ended September 30, 2017 decreased $65 million, or 11%, to $548 million, primarily due to an8% decrease in the total number of broadband subscribers since September 30, 2016, and a decline in revenue of approximately $22 million due to the sale of our Frontier Secure Strategic Partnerships business. Nonswitched access revenues for the three months ended September 30, 2017

37

PART I. FINANCIAL INFORMATION (Continued)

FRONTIER COMMUNICATIONS CORPORATION AND SUBSIDIARIES

decreased $25 million, or 6%, to $408 million, primarily due to lower monthly recurring revenues for wireless backhaul and other carrier services.

Consolidated data and Internet services revenue for the nine months ended September 30, 2017 increased $243 million as compared with 2016. Consolidated data services revenue for the nine months ended September 30, 2017 increased $128 million, or 8%, to $1,696 million as compared with 2016. Excluding additional data service revenue from the CTF Operationsfor the first quarter of 2017, revenue for the first nine months decreased $111 million, or 7%, driven by a reduction in revenue of $22 million as a result of the sale of the Frontier Secure Strategic Partnerships businessin May of 2017 and a decrease in the total number of broadband subscribers.

Consolidated nonswitched access revenues for the nine months ended September 30, 2017 increased $115 million or 10% to $1,277 million as compared with 2016. Excluding additional nonswitched access revenue from the CTF Operationsfor the first quarter of 2017,revenue decreased $67 million, or 6%, due to lower monthly recurring revenue for wireless backhaul and other carrier services. We expect wireless data usage to continue to increase, which may drive the need for additional wireless backhaul capacity. Despite the need for additional capacity, in the near term, we anticipate that our overall wireless backhaul revenues (which comprise approximately 2.9% of consolidated total revenues) will continue to decline in 2017, as our carrier customers migrate to Ethernet solutions at lower price points or migrate to our competitors.

Voice Services

Voice services include traditional local and long distance wireline services, data-based Voice over Internet Protocol (VoIP) services, as well as voice messaging services offered to our consumer and commercial customers. Voice services also include the long distance voice origination and termination services that we provide to our commercial customers and other carriers.

Voice services revenue for the three months ended September 30, 2017 decreased $107million, or 13%, to $702 million as compared with 2016, primarily due to the continued loss of voice customers and decreases in long distance revenue among those customers that do not have a bundled long distance plan.  

Voice services revenue for the nine months ended September 30, 2017 increased $65 million, or 3%, to $2,177 million as compared with 2016. Excluding additional voice services revenue from the CTF Operationsfor the first quarter of 2017, revenues decreased $262 million, or 12%, due to the continued loss of voice customers and decreases in long distance revenue.  

Video Services

Video servicesinclude revenues generated from services provided directly to consumer customers through the FiOS video and Vantage video brands, and through DISH satellite TV services.

Video services revenue for the three months ended September 30, 2017 decreased $74 million, or 19%, to $318 millionas compared with 2016 due to a decrease in the total number of video subscribers.

Video services revenue for the nine months ended September 30, 2017 increased $115 million, or 13%, to $994 million compared with 2016. Excluding additional video services revenue from the CTF Operations for the first quarter of 2017,  revenues decreased $166 million, or 19%, due to a decrease in the total number of video subscribers.

Other 

Other customer revenue includes sales of customer premise equipment to our commercial customers and directory services, less our provision for bad debts.

Other revenue for the three months ended September 30, 2017 increased $11 million, or 15%, as compared with 2016 primarily due to a decrease in uncollectibles, partially offset by a decrease in customer premise equipment sales during the third quarter of 2017. Other revenue for the nine months ended September 30, 2017 increased $13 million, or 6%. Excluding additional other revenue from the CTF Operations for the first quarter of 2017, revenues increased $8 million due to a decrease in uncollectibles, partially offset bya decrease in maintenance contracts.

FRONTIER COMMUNICATIONS CORPORATION AND SUBSIDIARIES

Switched Access and Subsidy

Switched access and subsidy revenues include revenues derived from allowing other carriers to use our network to originate and/or terminate their local and long distance voice traffic (“switched access”). These services are primarily billed on a minutes-of-use basis applying tariffed rates filed with the FCC or state agencies. We also receive cost subsidies from state and federal authorities, including the Connect America Fund.

Switched access and subsidy revenue for the three months ended September 30, 2017 decreased $14 million, or 7%, as compared with 2016. Switched access revenue decreased $4 million for the three months ended September 30, 2017, primarily due to the impact of the decline in minutes of use related to access line losses and the displacement of minutes of use by wireless and other communications services, combined with the lower rates required by the FCC’s 2011 Order on intercarrier compensation reform. Subsidy revenues decreased $10 million for the three months ended September 30, 2017, primarily due to one-time true-up payments and phasedown support recognized in the second quarter of 2016 in connection with the CAF Phase II program.

Switched access and subsidy revenue for the nine months ended September 30, 2017 decreased $12 million, or 2%, as compared with 2016.  Switched access revenue decreased $1 million for the nine months ended September 30, 2017, primarily due to the impact of the decline in minutes of use related to access line losses and the displacement of minutes of use by wireless and other communications service, combined with the lower rates required by the FCC’s 2011 Order on intercarrier compensation refund.  Excluding additional switched access revenue from the CTF Operationsfor the first quarter of 2017,revenue decreased $15 million, or 11%.Subsidy revenues for the nine months ended September 30, 2017 decreased $11 million.  Excluding additional subsidy revenue from the CTF Operationsfor the first quarter of 2017,revenue decreased $46 million, or 10%. We expect that switched access revenue will continue to decline in the fourth quarter of 2017.

The decrease was primarily driven by the accelerated method of amortization related to customer bases acquired in 2010 and 2014,offset by an increase in the value of the acquired CTF customer base as a result of final purchase accounting adjustments in 2017.Excluding additional expense from the CTF Operations for the first quarter of 2017, amortization expense decreased $62 million, or 13%, for the nine months ended September 30, 2017 as compared to the prior year period due to an increase in the value of the acquired CTF customer base subsequent to the second quarter of 2016, offset by the accelerated method of amortization related to customer bases acquired in 2010 and 2014.

GOODWILL IMPAIRMENT

As a result of the continued decline in the share price of our common stock ineach of the three quarters in 2017, we tested goodwill for impairment. The results of our quantitative goodwill impairment test resulted in a $670 million goodwill impairment in the second quarter of 2017, principally due to the decline in our profitability during the period (See Note 6). Results from our first and third quarter quantitative assessments did not result in additional goodwill impairment charges. Further declines in our profitability or share price could result in additional impairment in the future.

Acquisition costs include financial advisory, accounting, regulatory, legal and other related costs. Integration costs include expenses that are incremental and directly related to the acquisition, which were incurred to integrate the network and information technology platforms. Integration costs also include costs to achieve synergies and operational efficiencies directly associated with the acquisition.

We invested $19 million and $99 million in capital expenditures related to the CTF Acquisition during the nine months ended September 30, 2017 and 2016, respectively.

The Pension Plan contains provisions that provide certain employees with the option of receiving a lump sum payment upon retirement. Frontier’s accounting policy is to record these payments as a settlement only if, in the aggregate, they exceed the sum of the annual service and interest costs for the Pension Plan’s net periodic pension benefit cost. During the three and ninemonths ended September 30, 2017, lump sum pension settlement payments

to terminated or retired individuals amounted to  $87 million and $449 million,which exceeded the settlement threshold of $224 million, and as a result, Frontier recognized non-cash settlement charges totaling $77 million during 2017. The non-cash charge accelerated the recognition of a portion of the previously unrecognized actuarial losses in the Pension Plan. Additional pension settlement charges will be required in the fourth quarter of 2017, the amount of which will be dependent on the lump sum benefit payments made during the fourth quarter.

Restructuring costs and other charges consist of expenses related to changes in the composition of our business, including workforce reductions, the sale of business lines or divisions, and corresponding changes to our retirement plans.

Restructuring costs and other charges increased in the third quarter of 2017 compared to the third quarter of 2016 primarily due to a reduction in the workforce of approximately 300 employees in the third quarter of 2017.

Restructuring costs and other charges increased for the nine months ended September 30, 2017 compared to the nine months ended September 30, 2016 primarily due to a reduction in the workforce of approximately 850 employees and the loss on the sale of the Frontier Secure Strategic Partnerships business.

Investment and other income, net

Investment and other income, net for the nine months ended September 30, 2016 included interest income of $12 million, primarily due to interest earned on restricted cash. The decrease of $9 million was driven by less restricted cash on hand in 2017.

Loss on Extinguishment of Debt and Debt Exchanges

During the nine months ended September 30, 2017, Frontier recorded a loss on early extinguishment of debt of $89 million, primarily driven by a loss of $90 million resulting from debt buy backs during the second quarter, and slightly offset by a gain of $1 million resulting from buy backs in the third quarter.

During the nine months ended September 30, 2016, Frontier recorded a loss of $7 million resulting from the exchange of senior notes during the third quarter of 2016.

Interest expense

Interest expense for the three and nine months ended September 30, 2017 increased $5 million, or 1%, and $12 million, or 1%, as compared to the three and nine months ended September 30, 2016. We incurred additional interest of $19 million in 2017 on the $1,625 million term loan facility related to the CTF Acquisition. Our composite average borrowing rate as of September 30, 2017 and 2016 was 8.36% and8.55%, respectively.

Income tax benefit

Income tax benefit for the three and nine months ended September 30, 2017 decreased $15 million and increased $68 million, as compared to the three and nine months ended September 30, 2016. The effective tax rate on our pretax loss for the nine months ended September 30, 2017 was 26.5% as compared with 42.0% for the nine months ended September 30, 2016. The increase in income tax benefit was primarily due to the impact of the goodwill impairment incurred during the second quarter of 2017.

Diluted net loss attributable to Frontier common shareholders for the third quarter of 2017 was $92 million, or ($1.19) per share, as compared to a net loss of $135 million, or ($1.73) per share, in the third quarter of 2016,  and net loss for the first nine months of 2017 of $940 million, or ($12.07) per share, as compared to a net loss of $457 million, or ($5.87) per share for the first nine months of 2016.For the first nine months of 2017, the increase in net loss was primarily driven by the $532 million (after-tax) goodwill impairment charge incurred during the second quarter of 2017.

(b)  Liquidity and Capital Resources

Analysis of Cash Flows

As of September 30, 2017, we had cash and cash equivalents aggregating $286 million. Our primary source of funds during the nine months ended September 30, 2017 was cash on hand, cash generated from operations, and cash received from issuance of our Term Loan B. For the nine months ended September 30, 2017, we used cash flow from operations, cash on hand, and borrowings to principally fund all of our cash investing and financing activities, primarily capital expenditures, dividends and debt repayments.

At September 30, 2017, we had a working capital deficit of $531 million, including $166 million of long-term debt due within one year, as compared to a working capital deficit of $788 million at December 31, 2016. The decrease in the working capital deficit is primarily due to a decrease in current liabilities of $651 million, partially offset by a reduction in accounts receivable of $158 million. 

Cash Flows provided by Operating Activities

Cash flows provided by operating activities increased $223 million to $1,185 million for the nine months ended September 30, 2017 as compared with the prior year period. The increase was primarily the result of the addition of our CTF Operations, partially offset by unfavorable changes in working capital, along with higher interest expense.

We received $4 million and $35 million in cash tax refunds during the nine months ended September 30, 2017 and 2016, respectively.

In connection with the CTF Acquisition, Frontier recognized acquisition and integration costs of $15 million during the first nine months of 2017 compared to $387 million during the first nine months of 2016. Interest expense of $581 million was incurred during the first nine months of 2017 related to the September 2015 debt offering and the term loan credit agreement, dated as of August 12, 2015, with JPMorgan Chase Bank, N.A., as administrative agent, and the lenders party thereto, compared to $559 million in interest expense during the first nine months of 2016. Additionally, Frontier incurred $10 million of interest expense related to the Verizon Bridge Facility (as defined below) during the first nine months of 2016.

Cash Flows used by Investing Activities

Capital Expenditures

For the nine months ended September 30, 2017 and 2016, our capital expenditures were $865 million and $1,059 million, respectively, including $19 million and $99 million, respectively, of integration related capital expenditures associated with the CTF Acquisition. Capital expenditures related to CAF Phase II are included in our reported amounts for capital expenditures. We anticipate capital expenditures for business operations to be approximately $1.15 billion to $1.2 billion in 2017, as compared to $1.26 billion in 2016.

Cash Flows used by and provided from Financing Activities

Debt Reduction

During the first nine months of 2017, Frontier used cash on hand for the scheduled retirement of $328 million of debt, including $210 million of unsecured 8.25% senior notes at maturity, and contractual payments of principal for debt of $118 million. Additionally, Frontier used cash proceeds from the Term Loan B to retire $1,335 million of unsecured senior notes prior to maturity, consisting of $763 million of 8.875% Notes due 2020, $551 million of 8.500% Notes due 2020, $10 million of 9.250% Notes due 2021, $6 million of 7.125% Notes due 2019, and $5 million of 8.125% Notes due 2018. During the first nine months of 2017, Frontier recorded a loss on early extinguishment of debt of $89 million driven primarily by premiums paid to retire certain notes and unamortized original issuance costs, slightly offset by discounts received on the retirement of certain notes.

During the first nine months of 2016, Frontier used cash on hand to retire an aggregate principal amount of $280 million of debt, $189 million of which was senior unsecured debt and $91 million of which was secured debt.

Subject to limitations contained in our indentures and credit facilities, we may from time to time make repurchases of our debt in the open market, through tender offers,by exercising rights to call or in privately negotiated transactions. We may also refinance existing debt or exchange existing debt for newly issued debt obligations.

Capital Resources

We believe our operating cash flows, existing cash balances, existing revolving credit facility and access to the capital markets, as necessary, will be adequate to finance our working capital requirements, fund capital expenditures, make required debt interest and principal payments, pay taxes, pay dividends to our stockholders, and support our short-term and long-term operating strategies for the next twelve months. A number of factors, including but not limited to, losses of customers, pricing pressure from increased competition, lower subsidy and switched access revenues, and the impact of economic conditions may negatively affect our cash generated from operations. As of September 30, 2017, we had $42 million of debt maturing during the last three months of 2017; $743 million and $828 million of debt will mature in 2018 and 2019, respectively.

Term Loan and Revolving Credit Facilities

On February 27, 2017, Frontier entered into a first amended and restated credit agreement with JPMorgan Chase Bank, N.A., as administrative agent, and the lenders party thereto, pursuant to which Frontier combined its revolving credit agreement, dated as of June 2, 2014, and its term loan credit agreement, dated as of August 12, 2015. Under the JPM Credit Agreement, as further amended on June 15, 2017 by Increase Joinder No.1 (as so amended, the JPM Credit Agreement), Frontier has a $1,625 million senior secured term loan A facility (the Term Loan A) maturing on March 31, 2021, an $850 million undrawn secured revolving credit facility maturing on February 27, 2022 (the Revolver), and $1,500 million senior secured term loan B facility (the Term Loan B) maturing on June 15, 2024. The maturities of the Term Loan A, the Revolver, and the Term Loan B, in each case if still outstanding, will be accelerated in the following circumstances: (i) if, 91 days before the maturity date of any series of Senior Notes maturing in 2020, 2023 and 2024, more than $500 million in principal amount remains outstanding on such series; or (ii) if, 91 days before the maturity date of the first series of Senior Notes maturing in 2021 or 2022, more than $500 million in principal amount remains outstanding, in the aggregate, on the two series of Senior Notes maturing in such year. The determination of interest rates for each of the facilities under the JPM Credit Agreement is based on margins over the Base Rate (as defined in the JPM Credit Agreement) or over LIBOR, at the election of Frontier. Interest rate margins on the Term Loan A and Revolver (ranging from 0.75% to 1.75% for Base Rate borrowings and 1.75% to 2.75% for LIBOR borrowings) are subject to adjustment based on Frontier’s Total Leverage Ratio (as defined in the JPM Credit Agreement). Interest rate margins on the Term Loan B (2.75% for Base Rate borrowings and 3.75% for LIBOR borrowings) are not subject to adjustment. The security package under the JPM Credit Agreement includes pledges of the equity interests in certain Frontier subsidiaries and guaranties by certain Frontier subsidiaries. As of September 30, 2017, the revolving credit facility was fully available and no borrowings had been made thereunder. The revolving credit facility is available for general corporate purposes but may not be used to fund dividend payments.

Frontier has two senior secured credit agreements with CoBank, ACB, as administrative agent, lead arranger and a lender, and the other lenders party thereto: the first, for a $350 million senior term loan facility drawn in 2014 (the 2014 CoBank Credit Agreement), matures on October 24, 2019, and the second, for a $315 million senior term loan

FRONTIER COMMUNICATIONS CORPORATION AND SUBSIDIARIES

facility drawn in October 2016 (the 2016 CoBank Credit Agreement), matures on October 12, 2021. We refer to the 2014 CoBank Credit Agreement and the 2016 CoBank Credit Agreement collectively as the CoBank Credit Agreements.

Repayment of the outstanding principal balance under each of the CoBank Credit Agreements is being made in quarterly installments ($9 million, with respect to the 2014 CoBank Credit Agreement, and $8 million, with respect to the 2016 CoBank Credit Agreement), in each case with the remaining outstanding principal balance to be repaid on the applicable maturity date. Borrowings under each of the CoBank Credit Agreements bear interest based on the margins over the Base Rate (as defined in the applicable CoBank Credit Agreement) or over LIBOR, at the election of Frontier.

On March 29, 2017, Frontier amended the 2014 and 2016 CoBank Credit Agreements. The amendments provide that interest rate margins under each of these facilities will range from 0.875% to 3.875% for Base Rate borrowings and 1.875% to 4.875% for LIBOR borrowings, subject to adjustment based on our Total Leverage Ratio, as defined in each credit agreement. The interest rate on each of the facilities as of September 30, 2017 was LIBOR plus 3.875%. In addition, the amendments provide for increases in the maximum Leverage Ratio and expansion of the security package identical to those contained in the February 2017 amendment and restatement of the August 2015 JPM credit agreement.

Letters of Credit Facility

Frontier has a Continuing Agreement for Standby Letters of Credit with Deutsche Bank AG New York Branch and Bank of Tokyo – Mitsubishi UFJ, LTD. (the LC Agreements). As of September 30, 2017, $129 million of undrawn Standby Letters of Credit had been issued under the LC Agreements. Borrowings under the LC Agreement are secured by a pledge of the stock of certain Frontier subsidiaries and guaranties by certain Frontier subsidiaries.

Covenants

The terms and conditions contained in one or more of our indentures, the CoBank Credit Agreements and the JPM Credit Agreement include covenants that, among other things, place restrictions on the following: the incurrence of liens on our and our subsidiaries’ assets securing indebtedness; the incurrence of indebtedness by us and our subsidiaries; the payment of dividends and other restricted payments; selling or transferring assets; the maximum levels of our leverage and secured leverage ratios; and the entry into mergers or other changes in corporate control.  All of the above restrictions are subject to important, detailed qualifications and exceptions that are included in the JPM Credit Agreement, filed as an exhibit to our Quarterly Report on Form 10-Q for the quarterly period ended June 30, 2017 and in the CoBank Credit Agreements and our indentures, filed as exhibits to our Annual Report on Form 10-K for the fiscal year ended December 31, 2016. In addition, under the Certificate of Designations of our 11.125% Mandatory Convertible Preferred Stock, Series A, we would be restricted from paying dividends on our common stock if we failed to declare and pay dividends on our Series A Preferred Stock.

As of September 30, 2017, we were in compliance with all of our indenture and credit facility covenants.

Dividends

We intend to continue to pay regular quarterly dividends on our common and preferred stock. Our ability to fund a regular quarterly dividend will be impacted by our ability to generate cash from operations. Holders of the Series A Preferred Stock are entitled to receive cumulative dividends at an annual rate of 11.125% of the initial liquidation preference of $100 per share, or $11.125 per year per share. Series A Preferred Stock dividends of $161 million were paid during the nine month periods ended September 30, 2017 and 2016.

On July 26, 2017, we announced that our Board of Directors declared a regular quarterly cash dividend of $0.60 per share of common stock, payable on September29, 2017 to holders of record at the close of business on September 15, 2017. The Board of Directors also declared a regular quarterly cash dividend on Frontier’s 11.125% Series A Preferred Stock of $2.78125 per share, payable on September29, 2017 to holders of record at the close of business on September 15, 2017.

On October 31, 2017, we announced that our Board of Directors declared a regular quarterly cash dividend of $0.60 per share of common stock, payable on December 29, 2017 to holders of record at the close of business on December 15, 2017. The Board of Directors also declared a regular quarterly cash dividend on Frontier’s 11.125%

Mandatory Convertible Preferred Stock, Series A, of $2.78125 per share, payable on December 29, 2017 to holders of record at the close of business on December 15, 2017.

The declaration and payment of future dividends on our common stock is at the discretion of our Board of Directors, and will depend upon many factors, including our financial condition, results of operations, growth prospects, funding requirements, payment of cumulative dividends on Series A Preferred Stock, applicable law, restrictions in agreements governing our indebtedness and other factors our Board of Directors deems relevant.

Off-Balance Sheet Arrangements

We do not maintain any off-balance sheet arrangements, transactions, obligations or other relationships with unconsolidated entities that would be expected to have a material current or future effect upon our financial statements.

Future Commitments

On April 29, 2015, the FCC released its right of first refusal offer of support to price cap carriers under the CAF Phase II program, which is intended to provide long-term support for broadband in high cost unserved or underserved areas. In June 2015, Frontier accepted the CAF Phase II offer, which provides for $332 million in annual support through 2020, including $49 million in annual support related to the properties acquired in the CTF Acquisition, to make available 10 Mbps downstream/1 Mbps upstream broadband service to approximately 774,000 households across some of the 29 states where we 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 would be required to return a portion of the funds previously received.

Critical Accounting Policies and Estimates

The preparation of our financial statements requires management to make estimates and assumptions. There are inherent uncertainties with respect to such estimates and assumptions; accordingly, it is possible that actual results could differ from those estimates and changes to estimates could occur in the near term.

These critical accounting estimates have been reviewed with the Audit Committee of our Board of Directors.

Other than the updated indefinite-lived intangibles discussion below, there have been no material changes to our critical accounting policies and estimates from the information provided in Item 7. “Management Discussion and Analysis of Financial Condition and Results of Operations” included in our Annual Report on Form 10-K for the year ended December 31, 2016.

Indefinite-lived Intangibles

Our indefinite-lived intangibles consist of goodwill and trade name, which were generated as a result of business combinations. We test for impairment of these assets annually as of December 31 or more frequently, whenever events occur or facts and circumstances change that make it more likely than not that the fair value of a reporting unit has been reduced below its carrying amount. Events that might indicate impairment include, but are not limited to, strategic decisions made in response to economic and competitive conditions, the impact of the economic environment on our customer base, material negative changes in relationships with significant customers, and/or a significant decline in our stock price for a sustained period.

We early adopted ASU 2017-04 “Intangibles – Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment” (“ASU 2017-04”) during the second quarter of 2017. In accordance with ASU 2017-04, our annual goodwill impairment test (and interim test if determined to be necessary) will consist of comparing the fair value of our reporting unit to its carrying value. To the extent that the carrying value exceeds fair value, an impairment will be recognized. 

For the purpose of our goodwill impairment test, we first assess qualitative factors to determine if it is more likely than not that fair value of the reporting unit is less than the carrying amount. If it is less, an additional quantitative evaluation must be performed. Our quantitative assessment consists of using a market multiples approach to determine fair value.  Marketplace company comparisons and analyst reports within the telecommunications industry have historically supported a range of fair values of multiples between 5.0x and 7.9x annualized EBITDA (defined as operating income,

48

PART I. FINANCIAL INFORMATION (Continued)

FRONTIER COMMUNICATIONS CORPORATION AND SUBSIDIARIES

net of acquisition and integration costs, pension/OPEB expense, pension settlement costs, stock-based compensation expense, goodwill impairment, storm-related costs, and restructuring costs and other charges, as well as depreciation and amortization).

During 2017, our common stock has declined and traded at historically low prices. As a result, we tested goodwill for impairment in each of the three quarters in 2017. The second quarter quantitative assessment, as described above, resulted in a conclusion that the estimated enterprise fair value was lower than its carrying value, principally due to the decline in our profitability during the period. Accordingly, we recorded a goodwill impairment of $670 million in the second quarter of 2017. The first and third quarter quantitative assessments, did not result in goodwill impairment charges.In estimating the enterprise fair value we used 5.8x as the multiple in each of the three quarters in 2017. 

The market multiples approach that we use incorporates significant estimates and assumptions related to the forecasted results for the remainder of the year, including revenues, expenses, and the achievement of other cost synergies. Our assessment includes many qualitative factors that require significant judgment.Alternative interpretations of these factors could have resulted in different conclusions regarding the need for, or size of, an impairment.  Continued declines in our profitability or cash flows or in sustained low trading prices of our common stock may result in further impairment. 

The enterprise fair value is sensitive to the amount of EBITDA generated by Frontier and the EBITDA multiple used in the calculation. Significant changes in the assumptions or estimates used in our impairment analyses, such as a reduction in profitability and/or cash flows, could result in a non-cash goodwill and indefinite-lived intangible asset impairment charge and materially affect our operating results. The market multiples approach is sensitive to changes in the estimated annual EBITDA, with each $100 million change equating to approximately $580 million of estimated enterprise value. Similarly, a 1% change in the multiple used would affect the estimated enterprise value by approximately $200 million.  Sustained low trading prices for our common stock could also affect the reconciliation of our market capitalization and indicate further impairment. 

We also considered whether the carrying values of finite-lived intangible assets and property plant and equipment may not be recoverable or whether the carrying value of certain finite-lived intangible assets were impaired, noting no additional impairment was present as of September 30, 2017.

Recent Accounting Pronouncements

See Note 2 of the Notes to Consolidated Financial Statements included in Part I of this report for additional information related to recent accounting literature.

Regulatory Developments

On April 29, 2015, the FCC released offers of support to price cap carriers under the CAF Phase II program. The intent of these offers is to provide long-term support for carriers for establishing and providing broadband service with at least 10 Mbps downstream/1 Mbps upstream speeds in high-cost unserved or underserved areas. Frontier accepted the CAF Phase II offer in 29 states, including our CTF properties, which provides for $332 million in annual support through 2020 and a commitment to make broadband available to approximately 774,000 households. CAF Phase II support is a successor to the approximately $156 million in annual USF frozen high-cost support that Frontier had been receiving prior to the CTF acquisition, and the $42 million in annual transitional USF frozen high-cost support that Verizon had been receiving in California and Texas. In addition to the annual support levels, these amounts also include frozen support phasedown amounts in states where the annual CAF II funding is less than the prior annual frozen high-cost support funding. The frozen support phasedown support was $35 million in 2015 and $27 million in 2016, and is expected to be $17 million in 2017 and $6 million in 2018.

In February 2017, the FCC adopted an Order further explaining its competitive bidding process to continue to distribute CAF Phase II funding in those high-cost areas where price cap carriers declined the FCC’s offer of support. This auction could present a new support and deployment opportunity.

On August 4, 2017, the FCC adopted a Public Notice initiating the pre-auction process for the Connect America Fund Phase II auction. The Phase II auction will award up to $198 million annually for 10 years to service providers that commit to offer voice and broadband services to fixed locations in unserved high-cost areas; the auction will also account for other service elements such as the minimum data speed provided and data usage allowances.  The

49

FRONTIER COMMUNICATIONS CORPORATION AND SUBSIDIARIES

auction is likely to begin in 2018 though the exact timeframe is unknown.  Frontier has not yet determined whether it will participate in any competitive bid process at this time, and because Frontier accepted virtually all of its available CAF II support up front, we expect the funding available within our footprint to be limited.

On April 20, 2017, the FCC issued an Order that will significantly alter how Commercial Data Services are regulated once the rules go into effect. Specifically, the Order adopted a test to determine, on a county-by-county basis, whether price cap ILECs, like Frontier’s DS1 and DS3 services, will continue to be regulated. The test is likely to result in deregulation in a substantial number of our markets. Once implemented, the deregulation will allow Frontier to offer its DS1 and DS3 services in a manner that better responds to the competitive marketplace and allows for commercial negotiation. The areas that remain regulated may be subject to price fluctuations depending upon the price cap formula that year. Multiple parties have appealed and requested a stay of this Order.Frontier cannot predict the extent to which these regulatory changes will affect revenues at this time.

Item 3.  Quantitative and Qualitative Disclosures about Market Risk

We are exposed to market risk in the normal course of our business operations due to ongoing investing and funding activities, including those associated with our pension plan assets. Market risk refers to the potential change in fair value of a financial instrument as a result of fluctuations in interest rates and equity prices. We do not hold or issue derivative instruments, derivative commodity instruments or other financial instruments for trading purposes. As a result, we do not undertake any specific actions to cover our exposure to market risks, and we are not party to any market risk management agreements other than in the normal course of business. Our primary market risk exposures from interest rate risk and equity price risk are as follows:

Interest Rate Exposure

Our exposure to market risk for changes in interest rates relates primarily to the interest-bearing portion of our pension investment portfolio and the related actuarial liability for pension obligations, as well as our floating rate indebtedness. As of September 30, 2017,  80% of our total debt had fixed interest rates. We had no interest rate swap agreements in effect at September 30, 2017. We believe that our currently outstanding obligation exposure to interest rate changes is minimal. Our objectives in managing our interest rate risk are to limit the impact of interest rate changes on earnings and cash flows and to lower our overall borrowing costs. To achieve these objectives, only $3,537 million of our outstanding borrowings at September 30, 2017 have floating interest rates. Our undrawn $850 million revolving credit facility has interest rates that float with the LIBO Rate, as defined. Consequently, we have limited material future earnings or cash flow exposures from changes in interest rates on our debt. An adverse change in interest rates would increase the amount that we pay on our variable rate obligations and could result in fluctuations in the fair value of our fixed rate obligations. Based upon our overall interest rate exposure, a near-term change in interest rates would not materially affect our consolidated financial position, results of operations or cash flows.

At September 30, 2017, the fair value of our long-term debt was estimated to be approximately $15.5 billion, based on quoted market prices, our overall weighted average borrowing rate was 8.36% and our overall weighted average maturity was approximately six years. As of September 30, 2017, there has been no significant change in the weighted average maturity applicable to our obligations since December 31, 2016.

Equity Price Exposure

Our exposure to market risks for changes in equity security prices as of September 30, 2017 is limited to our pension plan assets. We have no other security investments of any significant amount.

Our Pension Plan assets decreased from $2,766 million at December 31, 2016 to $2,604 million at September 30, 2017, a decrease of $162 million, or 6%. This decrease was a result of benefit payments of $492 million, partially offset by positive investment returns of $270 million, net of investment management and administrative fees, and contributions in excess of the Differential (as defined below) of $60 million, during the first nine months of 2017.

As part of the CTF Acquisition, Verizon was required to make a cash payment to Frontier for the difference in assets initially transferred by Verizon into the Pension Plan and the related obligation (the Differential). In the third quarter of 2017,we received the $131 million Differential payment from Verizon, and have remitted an equivalent amount to the

FRONTIER COMMUNICATIONS CORPORATION AND SUBSIDIARIES

Pension Plan as of September 30, 2017. As the Differential was reflected as a receivable of the Pension Plan at December 31, 2016, the cash funding had no impact to plan assets.

Item 4.  Controls and Procedures

(a) Evaluation of disclosure controls and procedures

We carried out an evaluation, under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, regarding the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended). Based upon this evaluation, our principal executive officer and principal financial officer concluded, as of the end of the period covered by this report, September 30, 2017, that our disclosure controls and procedures were effective.

(b) Changes in internal control over financial reporting

We reviewed our internal control over financial reporting at September 30, 2017. There have been no changes in our internal control over financial reporting identified in an evaluation thereof that occurred during the third fiscal quarter of 2017 that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Item 1.Legal Proceedings

See Note 15 of the Notes to Consolidated Financial Statements included in Part I, Item 1 of this report. There have been no material changes to our legal proceedings from the information provided in Item 3. “Legal Proceedings” included in our Annual Report on Form 10-K for the year ended December 31, 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. Litigation is subject to uncertainty and the outcome of individual matters is not predictable. However, 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 materialadverse effect on our financial position, results of operations, or cash flows.

Item 1A.  Risk Factors

There have been no material changes to the Risk Factors described in Part 1,  Item 1A. “Risk Factors” in our Annual Report on Form 10-K for the fiscal year ended December 31, 2016.

Summary Of Significant Accounting Policies [Abstract]

Summary of Significant Accounting Policies

(1)   Summary of Significant Accounting Policies:

(a)  Basis of Presentation and Use of Estimates:

Frontier Communications Corporation and its subsidiaries are referred to as “we,” “us,” “our,” “Frontier,” or the “Company” in this report. Our interim unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP) and should be read in conjunction with the consolidated financial statements and notes included in our Annual Report on Form 10-K for the year ended December 31, 2016. Certain reclassifications of amounts previously reported have been made to conform to the current presentation, as described in Note 2 – Recent Accounting Literature. All significant intercompany balances and transactions have been eliminated in consolidation. These interim unaudited consolidated financial statements include all adjustments (consisting of normal recurring accruals) considered necessary, in the opinion of Frontier’s management, to present fairly the results for the interim periods shown. Revenues, net loss and cash flows for any interim periods are not necessarily indicative of results that may be expected for the full year. For our interim financial statements as of and for the period ended September 30, 2017, we evaluated subsequent events and transactions for potential recognition or disclosure through the date that we filed this Form 10-Q with the Securities and Exchange Commission (SEC). 

Effective April 1, 2016, Frontier’s scope of operations and balance sheet changed materially as a result of the completion of the CTF Acquisition, as described in Note 3 – Acquisitions. Historical financial data presented for Frontier is not indicative of the future financial position or operating results for Frontier, and includes the results of the CTF Operations, as defined in Note 3 – Acquisitions, from the date of acquisition on April 1, 2016.

The preparation of our interim financial statements in conformity with GAAP requires management to make estimates and assumptions that affect (i) the reported amounts of assets and liabilities at the date of the financial statements, (ii) the disclosure of contingent assets and liabilities, and (iii) the reported amounts of revenue and expenses during the reporting period. Actual results may differ from those estimates. Estimates and judgments are used when accounting for the allowance for doubtful accounts, asset impairments, indefinite-lived intangibles, depreciation and amortization, income taxes, business combinations, and pension and other postretirement benefits, among others.

We operate in one reportable segment. Frontier provides both regulated and unregulated voice, data and video services to consumer, commercial and wholesale customers and is typically the incumbent voice services provider in its service areas.

On July 10, 2017, we effected a one for fifteen reverse stock split of our common stock. The reverse stock split reduced the number of common shares issued (which includes outstanding shares and treasury shares) from approximately 1,193,000,000 shares to 80,000,000 shares, and reduced shares outstanding from 1,178,000,000 shares to 79,000,000 shares. In addition, and at the same time, the total number of shares of common stock that Frontier is authorized to issue changed from 1,750,000,000 shares to 175,000,000 shares. There was no change in the par value of the common stock, and no fractional shares were issued. All share and per share amounts in the financial statements and footnotes have been retroactively adjusted for all periods presented to give effect to the reverse stock split. As a result of our reverse stock split the conversion rates of our Series A Preferred Stock were proportionately adjusted.

(b)  Revenue Recognition:

Revenue is recognized when services are provided or when products are delivered to customers. Revenue that is billed in advance includes monthly recurring network access services (including data services), special access services and monthly recurring voice, video and related charges. The unearned portion of these fees is initially deferred as a component of “Advanced billings” on our consolidated balance sheet and recognized as revenue over the period that the services are provided. Revenue that is billed in arrears includes non-recurring network access services (including data services), switched access services and non-recurring voice and video services. The earned but unbilled portion of these fees is recognized as revenue in our consolidated statements of operations and accrued in “Accounts receivable” on our consolidated balance sheet in the period that the services are provided. Excise taxes are recognized as a liability when billed. Installation fees and their related direct and incremental costs are initially deferred and recognized as revenue and expense over the average term of a customer relationship. We recognize as current period expense the portion of installation costs that exceeds installation fee revenue.

Frontier collects various taxes from its customers and subsequently remits these taxes to governmental authorities. Substantially all of these taxes are recorded through the consolidated balance sheet and presented on a net basis in our consolidated statements of operations. We also collect Universal Service Fund (USF) surcharges from customers (primarily federal USF) that we have recorded on a gross basis in our consolidated statements of operations and included within “Revenue” and “Network related expenses” of $52 million and $60 million, and $160 million and $161 million for the three and nine months ended September 30, 2017 and 2016, respectively.

In 2015, we accepted the FCC’s Connect America Fund (CAF) Phase II offer of support, which is a successor to and augments the USF frozen high cost support that we had been receiving pursuant to a 2011 FCC order. Upon completion of the CTF Acquisition, Frontier assumed the CAF Phase II support and related obligations that Verizon had previously accepted with regard to California and Texas. CAF Phase II funding is a program intended to subsidize the high cost of establishing and delivering communications services to certain unserved or underserved areas. We are recognizing these subsidies into revenue on a straight line basis, which is consistent with how the costs related to these subsidies are being and are expected to be incurred. CAF Phase II is a multi-year program which requires us to deploy broadband to a specified number of households in each of the states where funding was accepted. Failure to meet our deployment obligations at the end of the program in 2020 would result in a return of a portion of the funding received. We regularly evaluate our ability to meet our broadband deployment obligations and adjust revenue accordingly.

We categorize our products, services and other revenues among the following five categories:

· Data and Internet services include broadband services for consumer and commercial customers. We provide data transmission services to high volume commercial customers and other carriers with dedicated high capacity circuits (“nonswitched access”) including services to wireless providers (“wireless backhaul”);

· Voice services include traditional local and long distance wireline services, Voice over Internet Protocol (VoIP) services, as well as a number of unified messaging services offered to our consumer and commercial customers. Voice services also include the long distance voice origination and termination services that we provide to our commercial customers and other carriers;

· Video services include services provided directly to consumer customers through the FiOS® and Vantage video brands, and through DISH® satellite TV services;

· Other includes sales of customer premise equipment to our commercial customers and directory services, less our provision for bad debts; and

· Switched Access and Subsidy revenues include revenues derived from allowing other carriers to use our network to originate and/or terminate their local and long distance voice traffic (“switched access”). These services are primarily billed on a minutes-of-use basis applying tariffed rates filed with the FCC or state agencies. We also receive cost subsidies from state and federal authorities, including the Connect America Fund Phase II.

The following table provides a summary of revenues from external customers by the categories of Frontier’s products and services:

	For the three months ended				For the nine months ended

Total revenue	$	2,251	$	2,524	$	6,911	$	6,487

(c)Goodwill and Other Intangibles:

Goodwill represents the excess of purchase price over the fair value of identifiable tangible and intangible net assets acquired in a business combination. We have undertaken studies to determine the fair values of assets and liabilities acquired as well as to allocate the purchase price to assets and liabilities, including property, plant and equipment, goodwill and other identifiable intangibles. We examine the carrying value of our goodwill and trade name annually as of December 31, or more frequently as circumstances warrant, to determine whether there are any impairment losses. We test for goodwill impairment at the “operating segment” level, as that term is defined in GAAP.

We determined that we have one operating segment based on a number of factors that our management uses to evaluate and run our business operations, including similarities of customers, products and technology. We tested goodwill for impairment as of September 30, 2017 as a result of the continued decline in share price of our common stock since June 30, 2017, the date of our last goodwill impairment test. Refer to Note 6 for a discussion of our goodwill impairment testing and results as of September 30, 2017. As stated in Note 2, we early adopted ASU No. 2017-04, “Simplifying the Test for Goodwill Impairment” during the second quarter of 2017 in conjunction with our goodwill impairment assessment.

Frontier amortizes finite-lived intangible assets over their estimated useful lives on the accelerated method of sum of the years digits. We review such intangible assets at least annually as of December 31 to assess whether any potential impairment exists and whether factors exist that would necessitate a change in useful life and a different amortization period.

Recent Accounting Pronouncements Not Yet Adopted

Revenue Recognition

In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2014-09, “Revenue from Contracts with Customers.” This standard, along with its related amendments, requires companies to recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which they expect to be entitled in exchange for those goods or services. This new standard will be adopted by Frontier for annual and interim reporting periods beginning with the first quarter of 2018.

The FASB allows two adoption methods under ASC 606. Companies are permitted to either apply the requirements retrospectively to all prior periods presented, or apply the requirements in the year of adoption, through a cumulative adjustment. We currently plan to adopt the standard in the first quarter of 2018, using the “modified retrospective method.” Under that method, we will apply the rules to all contracts existing as of January 1, 2018, recognizing, in beginning retained earnings, a cumulative-effect adjustment to include the establishment of contract asset and contract liability accounts with a corresponding adjustment to retained earnings. We will also provide additional disclosures comparing revenue recognized under ASC 606 to revenue as reported prior to the adoption of the standard.

Upon initial evaluation, we believe the key changes in the standard that impact our revenue recognition relate to the allocation of contract revenues among various services and equipment, and the timing of when those revenues are recognized. Additionally, the new standard will impact the timing of recognizing costs to obtain contracts. This includes a change in our existing policy related to the way we account for customer incentives, upfront non-recurring charges, commission payments, customer disputes and the allocation of discounts.

We are in the process of identifying and implementing changes to our systems, processes, policies and internal controls to meet the standard’s reporting and disclosure requirements.

Leases

In February 2016, the FASB issued ASU No. 2016 – 02, “Leases (Topic 842).” This standard establishes the principles to report transparent and economically neutral information about the assets and liabilities that arise from leases. Upon implementation, lessees will need to recognize almost all leases on their balance sheet as a right-of-use asset and a lease liability. It will be critical to identify leases embedded in a contract to avoid misstating the lessee’s balance sheet. For income statement purposes, the FASB retained a dual model, requiring leases to be classified as either operating or finance. Classification will be based on criteria that are largely similar to those applied in current lease accounting, but without explicit bright lines. Lessor accounting is similar to the current model, but updated to align with certain changes to the lessee model and the new revenue recognition standard. Existing sale-leaseback guidance, including guidance for real estate, is replaced with a new model applicable to both lessees and lessors. The new guidance is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years using modified retrospective application. Early application is permitted.  Frontier is in the initial stages of evaluating the potential impact this new standard may have on the consolidated financial statements.

Compensation – Retirement Benefits

In March 2017, the FASB issued ASU No. 2017-07, “Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost”. This standard was established to improve the presentation of net periodic pension cost and net periodic postretirement benefit cost by requiring that an employer disaggregate the service cost component of periodic benefit cost from the other components of net benefit cost. The amendments in the update also provide explicit guidance on how to present the service cost component and other components of net benefit cost in the income statement and allow only the service cost components of net benefit cost to be eligible for capitalization. The new guidance is effective for annual periods beginning after December 15, 2017, including interim periods within those annual periods and requires the presentation of the income statement to be applied retrospectively.  As a result of the standard, pension settlement costs and certain benefit costs which are currently included in operating expense, would be reported as other non-operating expense and will no longer be capitalized.  This will have a material impact on previously reported operating income and may have a material impact to operating income in future periods, however, the impact to pre-tax income is not expected to be material.

Recently Adopted Accounting Pronouncements

Share-Based Payments - Scope of Modification Accounting

In May 2017, the FASB issued ASU No. 2017-09, Scope of Modification Accounting which amends the scope of modification accounting for share-based payment arrangements. This standard provides guidance on the types of changes to the terms or conditions of share-based payment awards to which an entity would be required to apply modification accounting under ASC 718. Specifically, an entity would not apply modification accounting if the fair value, vesting conditions, and classification of the awards are the same immediately before and after the modification. The new guidance is effective for annual periods beginning after December 15, 2017, including interim periods within those annual periods and early adoption is permitted including in any interim period. Frontier has adopted this standard during the second quarter 2017, with no impact to our share-based payment awards.

Intangibles – Goodwill

In January 2017, the FASB issued ASU No. 2017-04, “Simplifying the Test for Goodwill Impairment.” This standard was established to simplify how an entity is required to test goodwill for impairment by eliminating Step 2from the goodwill impairment test. Step 2 measures a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of that goodwill. Under the amendments in this Update, an entity should perform its annual, or interim, goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An entity should recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. Additionally, an entity should consider income tax effects from any tax deductible goodwill on the carrying amount of the reporting unit when measuring the goodwill impairment loss, if applicable. The FASB also eliminated the requirements for any reporting unit with a zero or negative carrying amount to perform a qualitative assessment and, if it fails that qualitative test, to perform Step 2 of the goodwill impairment test. Therefore, the same impairment assessment applies to all reporting units. An entity is required to disclose the amount of goodwill allocated to each reporting unit with a zero or negative carrying amount of net assets. An entity still has the option to perform the qualitative assessment for a reporting unit to determine if the quantitative impairment test is necessary. Frontier early adopted this standard during the second quarter of 2017 in conjunction with our goodwill impairment assessment. See Note 1 and Note 6 for further discussion.

Compensation – Stock Compensation

In March 2016, the FASB issued ASU No. 2016-09, “Improvements to Employee Share-Based Payment Accounting,” to amend ASC Topic 718, “Compensation – Stock Compensation.” The ASU is part of the FASB’s ongoing simplification initiative, which is designed to reduce cost and complexity while maintaining or improving the usefulness of the information provided to the users of financial statements. The simplifications address a variety of areas for public entities, including the following: 1) accounting for income taxes, 2) classification of excess tax benefits on the statement of cash flows, 3) forfeitures, 4) minimum statutory tax withholding requirements, 5) classifications of employee taxes paid on the statement of cash flows when an employer withholds shares for tax withholding purposes, and 6) classification of awards with repurchase features. This guidance was effective for Frontier as of the third quarter of 2017.  During the nine months ended September 30, 2017, Frontier recognized $2millionof income tax expense and recorded a cumulative effect adjustment to beginning accumulated deficit of $1 million to recognize all unrecognized deferred tax benefits recorded as of January 1, 2017. For the nine months ended September 30, 2016, Frontier reclassified $10 million of taxes paid on behalf of employees related to shares withheld from “Cash flows provided from (used by) operations” to “Cash flows used by financing activities” in accordance with the new standard.

Acquisitions

(3)  Acquisitions:

The CTF Acquisition

On April 1, 2016, Frontier acquired the wireline operations of Verizon Communications, Inc. in California, Texas and Florida (the CTF Operations) for a purchase price of $10,540 million in cash and assumed debt (the CTF Acquisition), pursuant to the February 5, 2015 Securities Purchase Agreement, as amended. The final allocation of the purchase price presented below represents the effect of recording the fair value of assets acquired and liabilities assumed as of the date of the CTF Acquisition, based on the total transaction cash consideration of $9,871 million.

($ in millions)
Current assets	$	353
Property, plant & equipment		6,096
Goodwill		2,606
Other intangibles - primarily customer list		2,262
Current liabilities		(579)
Long-term debt		(544)
Other liabilities		(323)
Total net assets acquired	$	9,871

The fair value estimates related to the allocation of the purchase price to Other intangibles were revised and updated during the first quarter of 2017 from the previous estimates as of December 31, 2016. The allocation that was reported as of December 31, 2016 for Other intangibles increased $100 million, from $2,162 million to $2,262 million. These measurement period adjustments resulted in$20 million of amortization expense during the first quarter of 2017 that would have been recorded in 2016 if the adjustments had been recognized as of the acquisition date.Other adjustments to the allocation of the purchase price for the CTF Acquisition during the first quarter of 2017 resulted in a $140million decrease in Property, plant & equipment, a $61million increase in Current liabilities, and a $98million increase in Goodwill.

The total consideration exceeded the net estimated fair value of the assets acquired and liabilities assumed by $2,606 million, which we recognized as goodwill. This goodwill is attributable to strategic benefits, including enhanced financial and operational scale, market diversification and leveraged combined networks that we expect to realize. This amount of goodwill associated with the CTF Acquisition will be deductible for income tax purposes.

The following unaudited pro forma financial information presents the combined results of operations of Frontier and the CTF Operations as if the CTF Acquisition had occurred as of January 1, 2016. The pro forma information is not necessarily indicative of what the financial position or results of operations actually would have been had the CTF Acquisition been completed as of January 1, 2016. In addition, the unaudited pro forma financial information is not indicative of, nor does it purport to project, the future financial position or operating results of Frontier. The unaudited pro forma financial information excludes acquisition and integration costs and does not give effect to any estimated and potential cost savings or other operating efficiencies that may result from the CTF Acquisition.

Acquisition and Integration Costs

Acquisition costs include financial advisory, accounting, regulatory, legal and other related costs. Integration costs include expenses that are incremental and directly related to the acquisition, which were incurred to integrate the network and information technology platforms.  Integration costs also include costs to achieve synergies and operational efficiencies directly associated with the acquisition.

Frontier incurred operating expenses related to the CTF Acquisition as follows:

We adopted new estimated remaining useful lives for certain plant assets as of October 1, 2016, as a result of an annual independent study of the estimated remaining useful lives of our plant assets, with an insignificant impact to depreciation expense.

In 2017, we sold certain properties, generating $102 million in net proceeds, of which $97 million relates to property subject to leasebacks. For these properties, we have deferred$66 million in related gains that will be amortized over the related lease terms of two years. For the nine months ended September 30, 2017, amortization of these deferred gains totaled $14 million, which are included in “Selling, general and administrative expenses” on our consolidated income statement. We have remaining deferred gain balances of $52  million, which are included in “Other liabilities”.

Goodwill And Other Intangibles

(6)  Goodwill and Other Intangibles:  

The activity in goodwill from January 1, 2017 to September 30, 2017 was as follows:

($ in millions)
Balance at January 1, 2017	$	9,674
CTF Acquisition adjustments		98
Impairment		(670)
Balance at September 30, 2017	$	9,102

We are required to perform impairment tests related to our goodwill annually, which we perform as of December 31, or sooner if an indicator of impairment occurs. Due to the continued decline in our stock price we had triggering events in each of the three quarters in 2017.

We use a market multiples approach to determine fair value. Marketplace company comparisons and analyst reports within the telecommunications industry have historically supported a range of fair values of multiples between 5.0x and 7.9x annualized EBITDA (defined as operating income, net of acquisition and integration costs, pension/OPEB expense, pension settlement costs, stock-based compensation expense, goodwill impairment, storm-related costs, and restructuring costs and other charges, as well as depreciation and amortization). We estimated the enterprise fair value using a multiple of 5.8x EBITDA.

Our second quarter quantitative assessment indicated that the carrying value of the enterprise exceeded its fair value and, therefore, an impairment existed, principally due to the decline in our profitability during the second quarter of 2017. We elected to early adopt the simplified goodwill method under ASU 2017-04, and recorded our goodwill impairment based on the amount that the enterprise carrying value exceeded the fair value, which resulted in a goodwill impairment of $670 million. 

Our first and third quarter quantitative assessments indicated that the fair value of the enterprise exceeded its carrying value and, therefore, no indication of impairment existed in either period.

The market multiples approach that we use incorporates significant estimates and assumptions related to the forecasted results for the remainder of the year including revenues, expenses, and the achievement of other cost synergies.Our assessment includes many qualitative factors that require significant judgment. Alternative interpretations of these factors could have resulted in different conclusions regarding the need for, or size of, an impairment. Continued declines in our profitability or cash flows or in the sustained, historically low trading prices of our common stock may result in further impairment.

We also considered whether the carrying values of finite-lived intangible assets and property plant and equipment may not be recoverable or whether the carrying value of certain indefinite-lived intangible assets were impaired, noting no additional impairment was present as of September 30, 2017.

The components of other intangibles are as follows:

Amortization expense primarily represents the amortization of our customer base acquired as a result of the CTF Acquisition, the acquisition of AT&T wireline properties in Connecticutin 2014 and the acquisition of certain Verizon properties in 2010 with each based on a useful life of 8 to 12 years on an accelerated method.

(4)Represents borrowings under the JPM Credit Agreement Term Loan B, as defined below.

(5)Interest rate represents a weighted average of the stated interest rates of multiple issuances.

In September 2017, Frontier used proceeds from Term Loan B (see definition and note discussion below)to retire $24 million of 8.500% Notes due 2020, $10 million of 9.250% Notes due 2021, $6 million of 7.125% Notes due 2019, and $5 million of 8.125% Notes due 2018.  Frontier recorded a gain of $1 million driven primarily by discounts on the retirement of the notes. On April 17, 2017, Frontier used cash available on hand to retire $210 million of 8.25% Senior Notes that matured on such date.

In June 2017, Frontier used cash proceeds from Term Loan B (see definition and note discussion below) to retire $763 million of 8.875% Notes due 2020 and $527 million of 8.500% Notes due 2020. Frontier recorded a loss on early extinguishment of debt of $90 million driven by premiums paid to retire the notes and unamortized original issuance costs.

On February 27, 2017, Frontier entered into a first amended and restated credit agreement with JPMorgan Chase Bank, N.A., as administrative agent, and the lenders party thereto, pursuant to which Frontier combined its revolving credit agreement, dated as of June 2, 2014, and its term loan credit agreement, dated as of August 12, 2015. Under the JPM Credit Agreement, as further amended on June 15, 2017 by Increase Joinder No.1 (as so amended, the JPM Credit Agreement), Frontier has a $1,625 million senior secured term loan A facility (the Term Loan A) maturing on March 31, 2021, an $850 million undrawn secured revolving credit facility maturing on February 27, 2022 (the Revolver), and $1,500 million senior secured term loan B facility (the Term Loan B) maturing on June 15, 2024.  The maturities of the Term Loan A, the Revolver, and the Term Loan B, in each case if still outstanding, will be accelerated in the following circumstances: (i) if, 91 days before the maturity date of any series of Senior Notes maturing in 2020, 2023 and 2024, more than $500 million in principal amount remains outstanding on such series; or (ii) if, 91 days before the maturity date of the first series of Senior Notes maturing in 2021 or 2022, more than $500 million in principal amount remains outstanding, in the aggregate, on the two series of Senior Notes maturing in such year. The determination of interest rates for each of the facilities under the JPM Credit Agreement is based on margins over the Base Rate (as defined in the JPM Credit Agreement) or over LIBOR, at the election of Frontier. Interest rate margins on the Term Loan A and Revolver (ranging from 0.75% to 1.75% for Base Rate borrowings and 1.75% to 2.75% for LIBOR borrowings) are subject to adjustment based on Frontier’s Total Leverage Ratio (as defined in the JPM Credit Agreement). The interest rate on the Term Loan A as of September 30, 2017 was LIBOR plus 2.75%.  Interest rate margins on the Term Loan B (2.75% for Base Rate borrowings and 3.75% for LIBOR borrowings) are not subject to adjustment. The security package under the JPM Credit Agreement includes pledges of the equity interests in certain Frontier subsidiaries and guaranties by certain Frontier subsidiaries. As of September 30, 2017, the revolving credit facility was fully available and no borrowings had been made thereunder. The revolving credit facility is available for general corporate purposes but may not be used to fund dividend payments.

Frontier has two senior secured credit agreements with CoBank, ACB, as administrative agent, lead arranger and a lender, and the other lenders party thereto: the first, for a $350 million senior term loan facility drawn in 2014 (the 2014 CoBank Credit Agreement), matures on October 24, 2019, and the second, for a $315 million senior term loan facility drawn in October 2016 (the 2016 CoBank Credit Agreement), matures on October 12, 2021. We refer to the 2014 CoBank Credit Agreement and the 2016 CoBank Credit Agreement collectively as the CoBank Credit Agreements.

Repayment of the outstanding principal balance under each of the CoBank Credit Agreements is being made in quarterly installments ($9 million, with respect to the 2014 CoBank Credit Agreement, and $8 million, with respect to the 2016 CoBank Credit Agreement), in each case with the remaining outstanding principal balance to be repaid on the applicable maturity date. Borrowings under each of the CoBank Credit Agreements bear interest based on the margins over the Base Rate (as defined in the applicable CoBank Credit Agreement) or over LIBOR, at the election of Frontier.

On March 29, 2017, Frontier amended the 2014 and 2016 CoBank Credit Agreements. The amendments provide that interest rate margins under each of these facilities will range from 0.875% to 3.875% for Base Rate borrowings and 1.875% to 4.875% for LIBOR borrowings, subject to adjustment based on our Total Leverage Ratio, as defined in each credit agreement. The interest rate on each of the facilities as of September 30, 2017 was LIBOR plus 3.875%. In addition, the amendments provide for increases in the maximum Leverage Ratio and expansion of the security package identical to those contained in the JPM Credit Agreement.

As of September 30, 2017, we were in compliance with all of our indenture and credit facility covenants.

Our scheduled principal payments are as follows as of September 30, 2017:

In calculating diluted net loss per common share for the three and nine months ended September 30, 2016, the effect of all common stock equivalents is excluded from the computation as the effect would be antidilutive.

Stock Options

For the three and nine months ended September 30, 2017 and 2016, previously granted options to purchase 2,664 shares, issuable under employee compensation plans were excluded from the computation of diluted earnings (loss) per share (EPS) for those periods because the exercise prices were greater than the average market price of our common stock and, therefore, the effect would be antidilutive.

Stock Units

At September 30, 2017 and 2016, we had 161,020 and 116,223 stock units, respectively, issued under the Non-Employee Directors’ Deferred Fee Equity Plan (Deferred Fee Plan), the Non-Employee Directors’ Equity Incentive Plan (Directors’ Equity Plan),  the 2013 Equity Incentive Plan and the 2017 Equity Incentive Plan. These securities have not been included in the diluted EPS calculation for the three months ended September 30, 2017 and 2016 and the nine months ended September 30, 2016 because their inclusion would have an antidilutive effect. Compensation costs associated with the issuance of stock unitswere ($4)million for the nine months ended September 30, 2017. There were no compensation costs associated with the issuance of stock units for the nine months ended September 30, 2016.

Mandatory Convertible Preferred Stock

The impact of the common share equivalents associated with approximately 19,250,000 shares of Series A Preferred stock were not included in the diluted EPS calculation as of September 30, 2017 and 2016, as their impact was antidilutive.

Stock Plans [Abstract]

Stock Plans

(12)Stock Plans:

All share and per share amounts in the tables below have been retroactively adjusted for all periods presented to give effect to the reverse stock split. See Note 1 – Summary of Significant Accounting Policies for additional details.

At September 30, 2017, we had seven stock-based compensation plans under which grants were made and awards remained outstanding. No further awards may be granted under six of the plans: the 1996 Equity Incentive Plan (the 1996 EIP), the Amended and Restated 2000 Equity Incentive Plan (the 2000 EIP), the 2009 Equity Incentive Plan (the 2009 EIP), the 2013 Equity Incentive Plan (the 2013 EIP), the Deferred Fee Plan and the Directors’ Equity Plan. At September 30, 2017, there were approximately 5,667,000shares authorized for grant and approximately 4,381,000 shares available for grant under the 2017 Equity Incentive Plan (the 2017 EIP and together with the 1996 EIP, the 2000 EIP,  the 2009 EIP and the 2013 EIPS, the EIPs). Our general policy is to issue treasury shares upon the grant of restricted shares and the exercise of options.

Performance Shares

On February 16, 2017, the Compensation Committee of our Boardof Directors granted approximately 157,400performance shares under the Frontier Long Term Incentive Plan (the LTIP) and set the operating cash flow performance goal for 2017, which applies to the first year in the 2017-2019 measurement period, the second year of the 2016-2018 measurement period and the third year of the 2015-2017 measurement period.

The following summary presents information regarding LTIP target performance shares as of September 30, 2017 and changes during the nine months then ended with regard to LTIP shares awarded under the 2013 EIP and the 2017 EIP:

	Number of
	Shares
	(in thousands)
Balance at January 1, 2017	190
LTIP target performance shares granted, net	211
LTIP target performance shares earned	(41)
LTIP target performance shares forfeited	(51)
Balance at September 30, 2017	309

For purposes of determining compensation expense, the fair value of each performance share is measured at the end of each reporting period and, therefore, will fluctuate based on the price of Frontier common stock as well as performance relative to the targets. For the nine months ended September 30, 2017 and 2016, we recognized net compensation expense, reflected in “Selling, general and administrative expenses,” of $0 and $4million, respectively, for the LTIP.

Restricted Stock

The following summary presents information regarding unvested restricted stock as of September 30, 2017 and changes during the nine months then ended with regard to restricted stock granted under the 2013 EIP and the 2017 EIP:

		Weighted
		Average
	Number of	Grant Date		Aggregate
	Shares	Fair Value		Fair Value
	(in thousands)	(per share)		(in millions)
Balance at January 1, 2017	549	$	78.00	$	28
Restricted stock granted	454	$	47.77	$	5
Restricted stock vested	(220)	$	79.78	$	(3)
Restricted stock forfeited	(119)	$	61.21
Balance at September 30, 2017	664	$	59.64	$	8

For purposes of determining compensation expense, the fair value of each restricted stock grant is estimated based on the average of the high and low market price of a share of our common stock on the date of grant, for shares granted prior to May 10, 2017. Beginning on May 10, 2017, the fair value of each restricted stock grant is estimated based on the closing price of a share of our common stock on the date of the grant. Total remaining unrecognizedcompensation cost associated with unvested restricted stock awards that is deferred at September 30, 2017 was $26million, and the weighted average vesting period over which this cost is expected to be recognized is approximately 1.5 years.

Shares of restricted stock granted during the first nine months of 2016 totaled 375,133. The total fair value of shares of restricted stock granted and vested at September 30, 2016 was approximately $23  million and $15  million, respectively. The total fair value of unvested restricted stock at September 30, 2016 was $37  million. The weighted average grant date fair value of restricted shares granted during the nine months ended September 30, 2016 was $78.60 per share.

We have granted restricted stock awards to employees in the form of our common stock. None of the restricted stock awards may be sold, assigned, pledged or otherwise transferred, voluntarily or involuntarily, by the employees until the restrictions lapse, subject to limited exceptions. The restrictions are time-based. Compensation expense, recognized in “Selling, general and administrative expenses,” of $14million for each of the nine month periods ended September 30, 2017 and 2016, has been recorded in connection with these grants.

Comprehensive Income (Loss) [Abstract]

Comprehensive Income (Loss)

(13)Comprehensive Income (Loss):

Comprehensive income (loss) consists of net income (loss) and other gains and losses affecting shareholders’ investment and pension/postretirement benefit (OPEB) liabilities that, under GAAP, are excluded from net loss.

The components of accumulated other comprehensive loss, net of tax at September 30, 2017 and 2016, and changes for the nine months then ended, are as follows:

($ in millions)	Pension Costs		OPEB Costs		Deferred Taxes on Pension and OPEB Costs		Total

As a result of the pension settlement accounting discussed in Note 14, the Frontier Communications Pension Plan (the Pension Plan) was remeasured as of September 30, 2017. This remeasurement resulted in a decrease in the discount rate from 4.10% at March 31, 2017 to 3.8% at June 30, 2017 and September 30, 2017, in addition to census data changes resulting in the recording of a loss on remeasurement to Other comprehensive income (loss) during each of the quarters. For the nine months ended September 30, 2017, Frontier recorded a net loss on remeasurement of $32 million, to Other comprehensive income (loss).  Additionally, Frontier recorded pension settlement charges  totaling $77million  ($48million net of tax) to Other comprehensive income (loss). Refer to Note 14 for details about the settlement accounting.

The significant items reclassified from each component of accumulated other comprehensive loss for the three andnine months ended September 30, 2017 and 2016 are as follows:

During the first nine months of 2017 and 2016, we capitalized $20  million and $18 million, respectively, of pension and OPEB expense into the cost of our capital expenditures, as the costs relate to our engineering and plant construction activities.

The Pension Plan contains provisions that provide certain employees with the option of receiving a lump sum payment upon retirement. Frontier’s accounting policy is to record these payments as a settlement only if, in the aggregate, they exceed the sum of the annual service and interest costs for the Pension Plan’s net periodic pension benefit cost. During the three and nine months ended September 30, 2017, lump sum pension settlement payments to terminated or retired individuals amounted to $87 million and $449 million, which exceeded the settlement threshold of $224 million, and as a result, Frontier recognized non-cash settlement charges totaling $77 million during the first nine months of 2017. The non-cash charge accelerated the recognition of a portion of the previously unrecognized actuarial losses in the Pension Plan. These non-cash charges increased our recorded net loss and accumulated deficit, with an offset to accumulated other comprehensive loss in shareholders’ equity. An additional pension settlement charge will be required in the fourth quarter of 2017, the amount of which will be dependent on the lump sum benefit payments made during the fourth quarter. As a result of the recognition of the settlement charges in the first nine months of 2017, the net pension plan liability was remeasured as of September 30, 2017, June 30, 2017 and March 31, 2017 to be $717 million, $711 million and $665million, respectively, as compared to the $699 million measured and recorded at December 31, 2016. The remeasured funded status of the Pension Plan was approximately 80%, as of September 30, 2017, similar to December 31, 2016. Frontier did not record any adjustment to the pension plan liability, beyond the settlement charge, as a result of this remeasurement.

Our Pension Plan assets decreased from $2,766 million at December 31, 2016 to $2,604  million at September 30, 2017, a decrease of $162 million, or  6%. This decrease was a result of benefit payments of $492 million, partially offset by positive investment returns of $270 million, net of investment management and administrative fees, and contributions in excess of the Differential (as defined below) of $60  million, during the first nine months of 2017.

As part of the CTF Acquisition, Verizon was required to make a cash payment to Frontier for the difference in assets initially transferred by Verizon into the Pension Plan and the related obligation (the Differential). In the third quarter of 2017,we received the $131 million Differential payment from Verizon, and have remitted an equivalent amount to the Pension Plan as of September 30, 2017. As the Differential was reflected as a receivable of the Pension Plan at December 31, 2016, the cash funding had no impact to plan assets.

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 $332million in annual support, including $49million in annual support related to the properties acquired in the CTF 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 would be required to return a portion of the funds previously received.

On April 20, 2017, the FCC issued an Order that will significantly alter how Commercial Data Services are regulated once the rules go into effect. Specifically, the Order adopted a test to determine, on a county-by-county basis, whether price cap ILECs’, like Frontier’s, DS1 and DS3 services will continue to be regulated. The test is likely to result in deregulation in a substantial number of our markets. Once implemented, the deregulation will allow Frontier to offer its DS1 and DS3 services in a manner that better responds to the competitive marketplace and allows for commercial negotiation. The areas that remain regulated may be subject to price fluctuations depending upon the price cap formula that year. Multiple parties have appealed and requested a stay of this Order. Frontier cannot predict the extent to which these regulatory changes will result in changes to revenues at this time. 

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, shareholder, regulatory, tort, claims of competitors and disputes with other carriers. 

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.

In October 2013, the California Attorney General’s Office notified certain Verizon companies, including one of the subsidiaries that we acquired in the CTF 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. We have accrued an amount for potential penalties that we deem to be probable and reasonably estimated, and we do not expect that any potential penalties, if ultimately incurred, will be material in comparison to the established accrual.

Summary Of Significant Accounting Policies [Abstract]

Basis of Presentation and Use of Estimates

(a)  Basis of Presentation and Use of Estimates:

Frontier Communications Corporation and its subsidiaries are referred to as “we,” “us,” “our,” “Frontier,” or the “Company” in this report. Our interim unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP) and should be read in conjunction with the consolidated financial statements and notes included in our Annual Report on Form 10-K for the year ended December 31, 2016. Certain reclassifications of amounts previously reported have been made to conform to the current presentation, as described in Note 2 – Recent Accounting Literature. All significant intercompany balances and transactions have been eliminated in consolidation. These interim unaudited consolidated financial statements include all adjustments (consisting of normal recurring accruals) considered necessary, in the opinion of Frontier’s management, to present fairly the results for the interim periods shown. Revenues, net loss and cash flows for any interim periods are not necessarily indicative of results that may be expected for the full year. For our interim financial statements as of and for the period ended September 30, 2017, we evaluated subsequent events and transactions for potential recognition or disclosure through the date that we filed this Form 10-Q with the Securities and Exchange Commission (SEC). 

Effective April 1, 2016, Frontier’s scope of operations and balance sheet changed materially as a result of the completion of the CTF Acquisition, as described in Note 3 – Acquisitions. Historical financial data presented for Frontier is not indicative of the future financial position or operating results for Frontier, and includes the results of the CTF Operations, as defined in Note 3 – Acquisitions, from the date of acquisition on April 1, 2016.

The preparation of our interim financial statements in conformity with GAAP requires management to make estimates and assumptions that affect (i) the reported amounts of assets and liabilities at the date of the financial statements, (ii) the disclosure of contingent assets and liabilities, and (iii) the reported amounts of revenue and expenses during the reporting period. Actual results may differ from those estimates. Estimates and judgments are used when accounting for the allowance for doubtful accounts, asset impairments, indefinite-lived intangibles, depreciation and amortization, income taxes, business combinations, and pension and other postretirement benefits, among others.

We operate in one reportable segment. Frontier provides both regulated and unregulated voice, data and video services to consumer, commercial and wholesale customers and is typically the incumbent voice services provider in its service areas.

On July 10, 2017, we effected a one for fifteen reverse stock split of our common stock. The reverse stock split reduced the number of common shares issued (which includes outstanding shares and treasury shares) from approximately 1,193,000,000 shares to 80,000,000 shares, and reduced shares outstanding from 1,178,000,000 shares to 79,000,000 shares. In addition, and at the same time, the total number of shares of common stock that Frontier is authorized to issue changed from 1,750,000,000 shares to 175,000,000 shares. There was no change in the par value of the common stock, and no fractional shares were issued. All share and per share amounts in the financial statements and footnotes have been retroactively adjusted for all periods presented to give effect to the reverse stock split. As a result of our reverse stock split the conversion rates of our Series A Preferred Stock were proportionately adjusted.

Revenue Recognition

(b)  Revenue Recognition:

Revenue is recognized when services are provided or when products are delivered to customers. Revenue that is billed in advance includes monthly recurring network access services (including data services), special access services and monthly recurring voice, video and related charges. The unearned portion of these fees is initially deferred as a component of “Advanced billings” on our consolidated balance sheet and recognized as revenue over the period that the services are provided. Revenue that is billed in arrears includes non-recurring network access services (including data services), switched access services and non-recurring voice and video services. The earned but unbilled portion of these fees is recognized as revenue in our consolidated statements of operations and accrued in “Accounts receivable” on our consolidated balance sheet in the period that the services are provided. Excise taxes are recognized as a liability when billed. Installation fees and their related direct and incremental costs are initially deferred and recognized as revenue and expense over the average term of a customer relationship. We recognize as current period expense the portion of installation costs that exceeds installation fee revenue.

Frontier collects various taxes from its customers and subsequently remits these taxes to governmental authorities. Substantially all of these taxes are recorded through the consolidated balance sheet and presented on a net basis in our consolidated statements of operations. We also collect Universal Service Fund (USF) surcharges from customers (primarily federal USF) that we have recorded on a gross basis in our consolidated statements of operations and included within “Revenue” and “Network related expenses” of $52 million and $60 million, and $160 million and $161 million for the three and nine months ended September 30, 2017 and 2016, respectively.

In 2015, we accepted the FCC’s Connect America Fund (CAF) Phase II offer of support, which is a successor to and augments the USF frozen high cost support that we had been receiving pursuant to a 2011 FCC order. Upon completion of the CTF Acquisition, Frontier assumed the CAF Phase II support and related obligations that Verizon had previously accepted with regard to California and Texas. CAF Phase II funding is a program intended to subsidize the high cost of establishing and delivering communications services to certain unserved or underserved areas. We are recognizing these subsidies into revenue on a straight line basis, which is consistent with how the costs related to these subsidies are being and are expected to be incurred. CAF Phase II is a multi-year program which requires us to deploy broadband to a specified number of households in each of the states where funding was accepted. Failure to meet our deployment obligations at the end of the program in 2020 would result in a return of a portion of the funding received. We regularly evaluate our ability to meet our broadband deployment obligations and adjust revenue accordingly.

We categorize our products, services and other revenues among the following five categories:

· Data and Internet services include broadband services for consumer and commercial customers. We provide data transmission services to high volume commercial customers and other carriers with dedicated high capacity circuits (“nonswitched access”) including services to wireless providers (“wireless backhaul”);

· Voice services include traditional local and long distance wireline services, Voice over Internet Protocol (VoIP) services, as well as a number of unified messaging services offered to our consumer and commercial customers. Voice services also include the long distance voice origination and termination services that we provide to our commercial customers and other carriers;

· Video services include services provided directly to consumer customers through the FiOS® and Vantage video brands, and through DISH® satellite TV services;

· Other includes sales of customer premise equipment to our commercial customers and directory services, less our provision for bad debts; and

· Switched Access and Subsidy revenues include revenues derived from allowing other carriers to use our network to originate and/or terminate their local and long distance voice traffic (“switched access”). These services are primarily billed on a minutes-of-use basis applying tariffed rates filed with the FCC or state agencies. We also receive cost subsidies from state and federal authorities, including the Connect America Fund Phase II.

The following table provides a summary of revenues from external customers by the categories of Frontier’s products and services:

Goodwill and Other Intangibles

(c)Goodwill and Other Intangibles:

Goodwill represents the excess of purchase price over the fair value of identifiable tangible and intangible net assets acquired in a business combination. We have undertaken studies to determine the fair values of assets and liabilities acquired as well as to allocate the purchase price to assets and liabilities, including property, plant and equipment, goodwill and other identifiable intangibles. We examine the carrying value of our goodwill and trade name annually as of December 31, or more frequently as circumstances warrant, to determine whether there are any impairment losses. We test for goodwill impairment at the “operating segment” level, as that term is defined in GAAP.

We determined that we have one operating segment based on a number of factors that our management uses to evaluate and run our business operations, including similarities of customers, products and technology. We tested goodwill for impairment as of September 30, 2017 as a result of the continued decline in share price of our common stock since June 30, 2017, the date of our last goodwill impairment test. Refer to Note 6 for a discussion of our goodwill impairment testing and results as of September 30, 2017. As stated in Note 2, we early adopted ASU No. 2017-04, “Simplifying the Test for Goodwill Impairment” during the second quarter of 2017 in conjunction with our goodwill impairment assessment.

Frontier amortizes finite-lived intangible assets over their estimated useful lives on the accelerated method of sum of the years digits. We review such intangible assets at least annually as of December 31 to assess whether any potential impairment exists and whether factors exist that would necessitate a change in useful life and a different amortization period.
