Description Of Business And Summary Of Significant Accounting Policies [Abstract]  
Description Of Business And Summary Of Significant Accounting Policies (1) Description of Business and Summary of Significant Accounting Policies:

(a)Description of Business:

Frontier Communications Parent, Inc. is a provider of communications services in the United States, with approximately 2.9 million broadband subscribers and approximately 13,300 employees, operating in 25 states. We were incorporated in 1935, originally under the name of Citizens Utilities Company and was known as Citizens Communications Company until July 31, 2008. Frontier and its subsidiaries are referred to as “we,” “us,” “our,” “Frontier,” or the “Company” in this report.

(b)Basis of Presentation and Use of Estimates:

Our consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP). Certain reclassifications of amounts previously reported have been made to conform to the current presentation. The consolidated financial statements include the accounts of Frontier Communications Parent, Inc., all consolidated subsidiaries and variable interest entities of which the Company is the primary beneficiary. All significant intercompany balances and transactions have been eliminated in consolidation.

In 2021, we recategorized our previous operating expenses categories (“Network access expenses” and “Network related expense”) into one expense line: “Cost of service”. All historical periods presented have been updated to conform to the new categorization. In addition, certain reclassifications of prior period balances have been made to conform to the current period presentation. For our financial statements as of and for the period ended December 31, 2023, we evaluated subsequent events and transactions for potential recognition or disclosure through the date that we filed this Form 10-K with the Securities and Exchange Commission (SEC).

The preparation of our 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 application of fresh start accounting, allowance for credit losses, asset impairments, indefinite-lived intangibles, depreciation and amortization, income taxes, and pension and other postretirement benefits, among others. For information about our use of estimates as a result of fresh start accounting, see Note 4.

Chapter 11 Bankruptcy Emergence

On April 14, 2020 (the “Petition Date”), Frontier Communications Corporation, a Delaware corporation (“Old Frontier”), and its subsidiaries (collectively with Old Frontier, the “Debtors”), commenced cases under chapter 11 (the “Chapter 11 Cases”) of title 11 of the United States Code (the “Bankruptcy Code”) in the U.S. Bankruptcy Court for the Southern District of New York (the “Bankruptcy Court”). On August 27, 2020, the Bankruptcy Court confirmed the Fifth Amended Joint Plan of Reorganization of Frontier Communications Corporation and its Debtor Affiliates Pursuant to Chapter 11 of the Bankruptcy Code (the “Plan” or the “Plan of Reorganization”), which was filed with the Bankruptcy Court on August 21, 2020, and on April 30, 2021 (the “Effective Date”), the Debtors satisfied the conditions precedent to consummation of the Plan as set forth in the Plan, and the Debtors emerged from the Chapter 11 Cases without any need for further action or order of the Bankruptcy Court. See Note 3 for additional information related to our emergence from Chapter 11 Cases.

Fresh Start Accounting

Upon emergence from bankruptcy, we adopted fresh start accounting in accordance with Accounting Standards Codification (ASC) Topic 852 – Reorganizations (ASC 852) and became a new entity for financial reporting purposes. As a result, the consolidated financial statements after the Effective Date are not comparable with the consolidated financial statements on or before that date as indicated by the “black line” division in the financial statements and footnote tables, which emphasizes the lack of comparability between amounts presented. References to “Successor” relate to our financial position and results of operations after the Effective Date. References to “Predecessor” refer to the financial position and results of operations of Old Frontier and its subsidiaries on or before the Effective Date. See Note 4 for additional information related to fresh start accounting.

During the Predecessor period, ASC 852 was applied in preparing the consolidated financial statements. ASC 852 requires the financial statements, for periods subsequent to the commencement of the Chapter 11 Cases, to distinguish transactions and events that are directly associated with the reorganization from the ongoing operations of the business. ASC 852 requires certain additional reporting for financial statements prepared between the bankruptcy filing date and the date of emergence from bankruptcy, including: (i) Reclassification of pre-petition liabilities that are unsecured, under-secured or where it cannot be determined that the liabilities are fully secured, to a separate line item on the consolidated balance sheet called, "Liabilities subject to compromise"; and (ii) Segregation of “Reorganization items, net” as a separate line on the consolidated statements of comprehensive loss, included within income from continuing operations.

Upon application of fresh start accounting, we allocated the reorganization value to our individual assets and liabilities, except for deferred income taxes, based on their estimated fair values in conformity with ASC Topic 805, Business Combinations. The amount of deferred taxes was determined in accordance with ASC Topic 740, Income Taxes. The Effective Date fair values of our assets and liabilities differed materially from their recorded values as reflected on the historical balance sheets, see Note 4.

(c) Changes in Accounting Policies:

The accounting policy differences between Predecessor and Successor include:

Universal Service Fund and Other Surcharges - We collect various taxes, Universal Service Fund (USF) surcharges (primarily federal USF), and certain other taxes, from its customers and subsequently remit them to governmental authorities. The Predecessor recorded USF and other taxes on a gross basis on the consolidated statement of income, included within “Revenue” and “Cost of service expense”. After emergence, the Successor records these USF and other taxes on a net basis.

Provision for Bad Debt - The Predecessor reported the provision for bad debt as a reduction of revenue. After emergence, the Successor reports bad debt expense as an operating expense included in “Selling, general, and administrative expenses”.

Contract Acquisition Costs - During the Predecessor period, certain commissions to obtain new customers were deferred and amortized over four years, which represented the estimated customer contract period. As a result of fresh start accounting, that assumption was reevaluated and the period of benefit for our retail customers was determined to be less than one year. As such, these costs are now expensed as incurred.

Actuarial Losses on Defined Benefit Plans - Historically, actuarial gains (losses) were recognized as they occurred and included in “Accumulated other comprehensive income (loss)” and were subject to amortization over the estimated average remaining service period of participants. As part of fresh start accounting, we have made an accounting policy election to recognize these gains and losses immediately in the period they occur as Investment and other income (loss) on the consolidated statement of income.

Government Grants Revenue - Certain governmental grants that were historically presented on a net basis as part of capital expenditures, are now presented on a gross basis and included in ”Revenue” on the consolidated statement of income.

Administrative Expenses - Historically, the Predecessor capitalized certain administrative expenses, that following emergence, are expensed during the period incurred and included in “Selling, general, and administrative expense” on the consolidated statement of income.

(d) Going Concern:

In accordance with the requirements of Accounting Standards Update (“ASU”) 2014-15, “Presentation of Financial Statements Going Concern (ASU 2014-15)”, and ASC 205, “Presentation of Financial Statements”, we have the responsibility to evaluate at each reporting period, including interim periods, whether conditions and/or events raise substantial doubt about the Company’s ability to meet its future financial obligations. In its evaluation for this report, management considered our current financial condition and liquidity sources, including current funds available, forecasted future cash flows and our conditional and unconditional obligations due within one year following the date of issuance of this Annual Report on Form 10-K.

Accordingly, the accompanying consolidated financial statements have been prepared assuming that we will continue as a going concern and contemplate the realization of assets and the satisfaction of liabilities in the normal course business.

(e)Cash Equivalents and Restricted Cash:

We consider all liquid investments with an original maturity of three months or less to be cash equivalents. Restricted cash amounts represent cash collateral required for certain Letter of Credit obligations and utility vendors and collateral for debt arrangements.

At December 31, 2023, the Company had $114 million in restricted cash. Pursuant to the terms of the Company’s securitized financing facility and secured fiber network revenue term notes, as described in Note 9, restricted cash is held in securitization escrow accounts. As of December 31, 2023, approximately $42 million is current restricted cash held for the purpose of paying interest and certain fees. In addition, as of December 31, 2023, approximately $72 million

is noncurrent restricted cash held for the purpose of satisfying the required liquidity reserve amount. We did not have any restricted cash as of December 31, 2022.

(f) Short-Term Investments:

Given the long-term nature of our fiber build, we have invested cash into short-term investments to improve interest income while preserving funding flexibility.

As of December 31, 2023, short-term investments of $1,075 million are comprised of term deposits earning interest in excess of traditional bank deposit rates, maturing between January 4, 2024, and May 2, 2024, and placed with banks with A-1/P-1 or equivalent credit quality. These short-term investments are in scope of ASC 320, Investments - Debt Securities. The short-term investments’ original maturity is greater than 90 days but less than one year, and they are classified as held to maturity, recorded as current assets, and are accounted for at amortized cost.

Other Investments

In connection with the closing of the securitization transaction, approximately $63 million in the form of U.S. Treasuries was deposited in an escrow account established with a trustee, for the purpose of paying interest and principal on $47 million in remaining debt of our subsidiary Frontier Southwest Incorporated. This balance is included in “Other assets” on our consolidated balance sheets and is restricted. See Note 9 for further details.

(g)Revenue Recognition:

Revenue for data and Internet services, voice services, video services and switched and non-switched access services is recognized as services are provided to customers. Services that are billed in advance include monthly recurring network access services (including data services), special access services, and monthly recurring voice, video, and related charges. Revenue is recognized by measuring progress toward the complete satisfaction of our performance obligations. The unearned portion of these fees is deferred as a component of “Advanced billings” on our consolidated balance sheet and recognized as revenue over the period that the services are provided. Services that are billed in arrears include 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 income and accrued in “Accounts receivable” on our consolidated balance sheet in the period that services are provided. Excise taxes are recognized as a liability when billed.

Satisfaction of Performance Obligations

We satisfy our obligations to customers by transferring goods and services in exchange for consideration received from the customer. The timing of our satisfaction of the performance obligation may differ from the timing of the customer’s payment.

Bundled Service and Allocation of Discounts

When customers purchase more than one service, revenue for each is determined by allocating the total transaction price based upon the relative stand-alone selling price of each service. We frequently offer service discounts as an incentive to customers, which reduce the total transaction price. Any incentives which are considered cash equivalents (e.g. gift cards) that are granted will similarly result in a reduction of the total transaction price. Cash equivalent incentives are accounted for on a portfolio basis and are recognized in the month they are awarded to customers.

Customer Incentives

In the process of acquiring and/or retaining customers, we may issue a variety of incentives aside from service discounts or cash equivalent incentives. Those incentives that have stand-alone value (e.g. gift cards not considered cash equivalents or free goods/services) are considered separate performance obligations. While these incentives are free to the customer, a portion of the consideration received from the customer is ascribed to them based upon their relative stand-alone selling price. These types of incentives are accounted for on a portfolio basis with both revenue and expense recognized in the month they are awarded to the customer. The earned revenue associated with these incentives is reflected in “Other” revenue while the associated costs are reflected in “Cost of Services”.

Upfront Fees

All non-refundable upfront fees assessed to our customers provide them with a material right to renew; therefore, they are deferred by creating a contract liability and amortized into “Data and Internet service revenue” for fees charged to our wholesale customers and “Other revenue” for fees charged to all other customers over the average customer life using a portfolio approach.

Customer Acquisition Costs

Sales commission expenses are recognized as incurred. According to ASC 606, incremental costs in obtaining a contract with a customer are deferred and recorded as a contract asset if the period of benefit is expected to be greater

than one year. For our retail customers, this period of benefit has been determined to be less than one year. As such, we applied the practical expedient that allows such costs to be expensed as incurred.

Taxes, Surcharges and Subsidies

We collect various taxes, Universal Service Funds (USF) surcharges (primarily federal USF), and certain other surcharges from our customers and subsequently remits these taxes to governmental authorities. During the predecessor period, USF and other surcharges amounted to $83 million during the four months ended April 30, 2021.

In June 2015, we accepted the FCC offer of support to price cap carriers under the Connect America Fund (“CAF”) Phase II program, which was intended to provide long-term support for broadband build commitments in high cost unserved or underserved areas. We recognized the FCC’s CAF Phase II subsidies into revenue on a straight-line basis over the seven-year funding term which ended on December 31, 2021. The FCC is reviewing carriers’ CAF II program completion data, and if the FCC determines that we did not satisfy certain applicable CAF Phase II requirements, we could be required to return a portion of the funds previously received and may be subject to certain other penalties, requirements and obligations. We have accrued an amount for any potential shortfall in the household build commitment 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 May 2022, we accepted the FCC offer under the Rural Digital Opportunity Fund (“RDOF”) Phase I program, which provides funding over a ten-year period to support the construction of broadband networks in rural communities across the country. We accepted $37 million in annual support through 2032 in return for our commitment to make broadband available to households within the RDOF eligible areas. We will recognize the FCC’s RDOF Phase I subsidies into revenue on a straight-line basis over the ten-year funding term which will end March 31, 2032. We are required to complete the RDOF deployment by December 31, 2028. Thereafter, the FCC will review carriers’ RDOF program completion data, and if the FCC determines that we did not satisfy applicable FCC RDOF requirements, we could be required to return a portion of the funds previously received and may be subject to certain other penalties, requirements and obligations. We accrue for any potential shortfall in the household build commitment that we deem to be probable and reasonably estimated.

(h)Property, Plant and Equipment:

Property, plant, and equipment are stated at original cost, including capitalized interest, or fair market value as of the date of acquisition for acquired properties. Maintenance and repairs are charged to operating expenses as incurred. The gross book value of routine property, plant and equipment retirements is charged against accumulated depreciation.

(i)Definite and Indefinite Lived Intangible Assets:

Intangible assets are initially recorded at estimated fair value. Old Frontier historically amortized its acquired customer lists and certain other finite-lived intangible assets over their estimated useful lives on an accelerated basis. Upon emergence from bankruptcy, customer relationship intangibles were established for business and wholesale customers. These intangibles are amortized on a straight-line basis over their assigned useful lives of between 11 and 16 years. Additionally, trademark and tradename assets established upon emergence are amortized on a straight-line basis over 5 years. We review such intangible assets annually, or more often if indicators of impairment arise, to determine whether there is evidence that indicates an impairment condition may exist that would necessitate a change in useful life and a different amortization period.

(j)Impairment of Long-Lived Assets and Long-Lived Assets to Be Disposed Of:

We review long-lived assets to be held and used, including customer lists and property, plant and equipment, and long-lived assets to be disposed of for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. Recoverability of assets to be held and used is measured by comparing the carrying amount of the asset to the future undiscounted net cash flows expected to be generated by the asset. Recoverability of assets held for sale is measured by comparing the carrying amount of the assets to their estimated fair market value. If any assets are considered to be impaired, the impairment is measured by the amount by which the carrying amount of the assets exceeds the estimated fair value. Also, we periodically reassess the useful lives of our long-lived assets to determine whether any changes are required.

(k)Lease Accounting:

We determine if an arrangement contains a lease at inception. Right-of-use (ROU) assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Operating and Finance lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. The operating and finance lease ROU asset also includes any lease payments made and excludes lease incentives. Our lease terms used in accounting for leases may reflect options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Lease expense for operating leases is recognized on a straight-line

basis over the lease term. ROU assets for operating leases are recorded to “Other Assets”, and the related liabilities recorded to “Other current liabilities”, and “Other liabilities” on our consolidated balance sheets. Assets subject to finance leases are included in “Property, Plant & Equipment”, with corresponding liabilities recorded to “Other current liabilities”, and “Other liabilities” on our consolidated balance sheets.

We assess potential impairments to our leases annually, or as indicators exist, if indicators of impairment arise to determine whether there is evidence that indicate an impairment condition may exist. We continue to review our real estate portfolio and, during the first quarter of 2022, determined to either terminate or market for sublease certain facilities leases, which triggered an impairment of $44 million for our finance and operating lease assets recorded as restructuring charges and other costs. See Note 11 for further details.

(l)Income Taxes and Deferred Income Taxes:

We file a consolidated federal income tax return. We utilize the asset and liability method of accounting for income taxes. Under the asset and liability method, deferred income taxes are recorded for the tax effect of temporary differences between the financial statement basis and the tax basis of assets and liabilities using tax rates expected to be in effect when the temporary differences are expected to reverse.

We recognize deferred tax assets to the extent that we believe that these assets are more likely than not to be realized. In making such a determination, we consider all available positive and negative evidence, including future reversals of existing taxable temporary differences, tax-planning strategies, and results of recent operations. If we determine that we are not able to realize a portion of our net deferred tax assets in the future, we would make an adjustment to the deferred tax asset valuation allowance, which would increase the provision for income taxes.

The tax effect of a change in tax law or rates included in income tax expense from continuing operations includes effect of changes in deferred tax assets and liabilities initially recognized through a charge or credit to other comprehensive income (loss). The residual tax effects typically are released when the item giving rise to the tax effect is disposed of, liquidated, or terminated.

(m) Stock Plans:

We have one stock-based compensation plan under which grants are made and awards remain outstanding. Awards under this plan may be made to employees, directors or consultants of the Company or its affiliates, as determined by the Compensation and Human Capital Committee of the Board. Awards may be made in the form of restricted stock, restricted stock units, incentive stock options, non-qualified stock options, stock appreciation rights or other stock-based awards, including awards with performance, market, and time-vesting conditions.

The compensation cost recognized is based on awards ultimately expected to vest. GAAP requires forfeitures to be estimated and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates.

Financial Accounting Standards Adopted During 2023

During the year ended December 31, 2023, we adopted, the Financial Accounting Standards Board’s (FASB) Accounting Standards Update (ASU) No. 2022-04, “Liabilities – Supplier Finance Programs (Subtopic 405-50): Disclosure of Supplier Finance Program Obligations” (ASU 2022-04), which establishes interim and annual reporting disclosure requirements about a company’s supplier finance programs for its purchase of goods and services. In the year of adoption, the disclosure of payment and other key terms under the programs and outstanding balances under the obligations also applies to interim reporting dates. As of December 31, 2023, we had $263 million of vendor financing liabilities included in “Other current liabilities” on our consolidated balance sheets. Refer to Note 21 for further details.

Financial Accounting Standards Not Yet Adopted

ASU No. 2023-09 – Income Taxes (Topic 740): Improvements to Income Tax Disclosures. The amendments in this Update require that public business entities on an annual basis (1) disclose specific categories in the rate reconciliation and (2) provide additional information for reconciling items that meet a quantitative threshold (if the effect of those reconciling items is equal to or greater than 5 percent of the amount computed by multiplying pretax income [or loss] by the applicable statutory income tax rate). For public business entities, the amendments in this Update are effective for annual periods beginning after December 15, 2024.

ASU No. 2023-07 – Segment Reporting (Topic 280): Improvements to reportable segment disclosures. The amendments in this update improve financial reporting by requiring disclosure of incremental segment information on an annual and

interim basis for all public entities to enable investors to develop more decision-useful financial analyses. Currently, Topic 280 requires that a public entity disclose certain information about its reportable segments. For example, a public entity is required to report a measure of segment profit or loss that the CODM uses to assess segment performance and make decisions about allocating resources. Topic 280 also requires other specified segment items and amounts, such as depreciation, amortization, and depletion expense, to be disclosed under certain circumstances. The amendments in this update do not change or remove those disclosure requirements. The amendments in this update also do not change how a public entity identifies its operating segments, aggregates those operating segments, or applies the quantitative thresholds to determine its reportable segments. The amendments in this update are effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted.

Emergence From The Chapter 11 Cases [Abstract]  
Emergence From The Chapter 11 Cases (3) Emergence from the Chapter 11 Cases:

On April 14, 2020, the Debtors commenced the Chapter 11 Cases in Bankruptcy Court. The Chapter 11 Cases were jointly administered under the caption In re Frontier Communications Corporation., et al., Case No. 20-22476 (RDD).

On August 27, 2020, the Bankruptcy Court entered the Order Confirming the Plan (the “Confirmation Order”).

On the Effective Date, the Debtors satisfied all conditions precedent required for consummation of the Plan as set forth in the Plan, the Plan became effective in accordance with its terms and the Debtors emerged from the Chapter 11 Cases without any need for further action or order of the Bankruptcy Court.

On the Effective Date, pursuant to the terms of the Plan (i) Old Frontier completed a series of transactions pursuant to which it transferred all of its assets in a taxable sale to an indirectly wholly owned subsidiary of Frontier Communications Parent, Inc., a Delaware corporation (“Frontier” or the “Company”), prior to winding down its business, (ii) all of the obligations under Old Frontier’s unsecured senior note indentures were cancelled, and (iii) in connection with emergence, we issued 244,401,000 shares of common stock that were transferred to holders of the allowed senior notes claims (as defined by the Plan) and the Restructuring Support Agreement was automatically terminated. For a description of our DIP financing and exit financing upon Emergence, see Note 9 Long-Term Debt.

Reorganization items incurred as a result of the Chapter 11 Cases presented separately in the accompanying consolidated statements of operations were as follows:

Reorganization Items and Liabilities Subject to Compromise

Effective on April 14, 2020, we began to apply the provisions of ASC 852, Reorganizations (ASC 852), which is applicable to companies under bankruptcy protection, and requires amendments to the presentation of certain financial statement line items. ASC 852 requires that the financial statements for periods including and after the filing of the Chapter 11 Cases distinguish transactions and events that are directly associated with the Restructuring from the ongoing operations of the business. Expenses (including professional fees), realized gains and losses, and provisions for losses that can be directly associated with the Restructuring must be reported separately as reorganization items, net in the consolidated statements of operations beginning April 14, 2020, the date of filing of the Chapter 11 Cases. Liabilities that may be affected by the Plan must be reported at the amounts expected to be allowed by the Bankruptcy Court, even if they may be settled for lesser amounts as a result of the Plan or negotiations with creditors. The amounts currently classified as liabilities subject to compromise may be subject to future adjustments depending on Bankruptcy Court actions, further developments with respect to disputed claims, determinations of secured status of certain claims, the values of any collateral securing such claims, or other events. Any resulting changes in classification will be reflected in subsequent financial statements. If there is uncertainty about whether a secured claim is undersecured, or will be impaired under the Plan, the entire amount of the claim is included with prepetition claims in Liabilities subject to compromise.

As a result of the filing of the Chapter 11 Cases on April 14, 2020, the classification of pre-petition indebtedness is generally subject to compromise pursuant to the Plan. Generally, actions to enforce or otherwise effect payment of pre-bankruptcy filing liabilities are stayed. Although payment of pre-petition claims generally is not permitted, the Bankruptcy Court granted the Company Parties authority to pay certain pre-petition claims in designated categories and subject to certain terms and conditions. This relief generally was designed to preserve the value of the Company Parties’ businesses and assets. Among other things, the Bankruptcy Court authorized the Company Parties’ to pay certain pre-petition claims relating to employee wages and benefits, taxes, and critical vendors. The Company Parties are paying and intend to pay undisputed post-petition liabilities in the ordinary course of business. In addition, the Company Parties may reject certain pre-petition executory contracts and unexpired leases with respect to their operations with the approval of the Bankruptcy Court. Any damages resulting from the rejection of executory contracts and unexpired leases are treated as general unsecured claims.

On the Effective Date, the Debtors satisfied all conditions precedent required for consummation of the Plan as set forth in the Plan, the Plan became effective in accordance with its terms and the Debtors emerged from the Chapter 11 Cases without any need for further action or order of the Bankruptcy Court.

On the Effective Date, pursuant to the terms of the Plan, all of the obligations under Old Frontier’s unsecured senior note indentures were cancelled, and in connection with emergence, we issued 244,401,000 shares of common stock that were transferred to holders of the allowed senior notes claims (as defined by the Plan) and the Restructuring Support Agreement was automatically terminated.

The accompanying consolidated balance sheet as of December 31, 2021 includes amounts classified as Liabilities subject to compromise, which represent liabilities we anticipate will be allowed as claims in the Chapter 11 Cases. These amounts represent our current estimate of known or potential obligations to be resolved in connection with the Chapter 11 Cases and may differ from actual future settlement amounts paid. Differences between liabilities estimated and claims filed, or to be filed, will be investigated, and resolved in connection with the claims resolution process.

Fresh Start Accounting

Dec. 31, 2023
Fresh Start Accounting [Abstract]  
Fresh Start Accounting (4) Fresh Start Accounting:

In connection with our emergence from bankruptcy and in accordance with ASC 852, we qualified for and adopted fresh start accounting on the Effective Date. We were required to adopt fresh start accounting because (i) the holders of existing voting shares of the Predecessor received less than 50% of the voting shares of the Successor, and (ii) the reorganization value of our assets immediately prior to confirmation of the Plan was less than the post-petition liabilities and allowed claims.

The adoption of fresh start accounting resulted in a new reporting entity for financial reporting purposes with no beginning retained earnings or deficit. The cancellation of all outstanding shares of Old Frontier common stock on the Effective Date

and issuance of new shares of common stock of the Successor caused a related change of control of the Company under ASC 852.

Upon the application of fresh start accounting, we allocated the reorganization value to our individual assets based on their estimated fair values. Each asset and liability existing as of the Effective Date, other than deferred taxes, have been stated at the fair value, and determined at appropriate risk-adjusted interest rates. Deferred taxes were determined in conformity with applicable accounting standards.

Reorganization value represents the fair value of the Successor’s assets before considering liabilities. Our reorganization value is derived from an estimate of enterprise value. Enterprise value represents the estimated fair value of an entity’s long-term debt and shareholders’ equity. In support of the Plan, the enterprise value of the Successor was estimated to be approximately $12.5 billion. The valuation analysis was prepared using financial information and financial projections and applying standard valuation techniques, including a risked net asset value analysis.

The Effective Date estimated fair values of certain of our assets and liabilities differed materially from their recorded values as reflected on the historical balance sheets. As a result of the application of fresh start accounting and the effects of the implementation of the Plan, our consolidated financial statements after April 30, 2021 are not comparable to our consolidated financial statements as of or prior to that date.

Reorganization Value

As set forth in the Plan of Reorganization, the enterprise value of the Successor Company was estimated to be between $10.5 billion and $12.5 billion. Based on the estimates and assumptions discussed below, we estimated the enterprise value to be $12.5 billion as of the Effective Date. We based our enterprise value on projections which included higher capital expenditures to enhance the network and would result in higher revenue and Earnings before interest, taxes, depreciation, and amortization (“EBITDA”).

Management, with the assistance of our valuation advisors, estimated the enterprise value (“EV”) of the Successor Company, which was approved by the Bankruptcy Court, using various valuation methodologies, including a Discounted Cash Flow analysis (DCF), the Guideline Public Company Method (GPCM), and the Guideline Transaction Method (GTM). Under the DCF analysis, the enterprise value was estimated by discounting the projections’ unlevered free cash flow by the Weighted Average Cost of Capital (WACC), we estimated rate of return. A terminal value was estimated by applying a Gordon Growth Model to the normalized level of cash flows in the terminal period. The Gordon Growth Model was based on the WACC and the perpetual growth rate, and the terminal value was added back to the discounted cash flows.

Under the GPCM, our enterprise value was estimated by performing an analysis of publicly traded companies that operate in a similar industry. A range of Enterprise Value / EBITDA (EV/EBITDA) multiples were selected based on the financial and operating attributes of Frontier relative to the comparable publicly traded companies. The selected range of multiples were applied to our forecasted EBITDA to estimate the enterprise value of the Company.

The GTM approach is similar to the GPCM, in that it relies on EV/EBITDA multiples but rather than of publicly traded companies, the multiples are based on precedent transactions. A range of multiples was derived by analyzing the operating and financial attributes of the acquired companies and the implied EV/EBITDA multiples. This range of multiples were then applied to the forecasted EBITDA of the Company to arrive an enterprise value.

The following table reconciles the enterprise value to the estimated fair value of the Successor common stock as of the Effective Date:

Costs to obtain customers have been reflected as part of intangible assets. Adjustment also reflects the elimination of certain contract assets and contract liabilities.

(9)Property Plant & Equipment – Reflects the decrease in net book value of property and equipment to the estimated fair value as of the Effective Date.

Personal property valued consisted of outside and inside plant network equipment, computers and software, vehicles, office furniture, fixtures and equipment, computers and software, and construction-in-progress. The fair value of our personal property was estimated using the cost approach, while the income approach was considered to assess economic sufficiency to support asset values. As a part of the valuation process, the third-party advisors’ diligence procedures included using internal data to identify and value assets.

Real property valued consisted of land, buildings, and leasehold improvements. The fair value was estimated using the cost approach and sales comparison (market) approach, with consideration of economic sufficiency to support certain asset values.

(10)Reflects the fair value adjustment to recognize trademark, trade name and customer relationship.

For purposes of estimating the fair values of customer relationships, we utilized an Income Approach, specifically, the Multi-Period Excess Earnings method, or MPEEM. The MPEEM estimates fair value based on the present value of the incremental after-tax cash flows attributable only to the subject intangible assets after deducting contributory asset charges. The cash flows attributable to the customer relationships were adjusted for contributory asset charges related to the working capital, fixed assets, trade name/trademarks and assembled workforce. The discount rate utilized to present-value the after-tax cash flows was based on the overall weighted cost of capital of the Company as well as the asset specific risks of the intangible assets. Changes in these inputs could have a significant impact on the fair value of the customer relationships intangible assets.

For purposes of estimating the fair value of trademarks and tradenames, an Income approach was used, specifically, the Relief from Royalty Method. The estimated royalty rates were historical third-party transactions regarding the licensing of similar type of assets as well as a review of historical assumptions used in prior transactions. The selected royalty rates were applied to the revenue generated by the trademarks and tradenames to determine the amount of royalty payments saved as a result of owning these assets. The forecasted cash flows were based on our projected revenues and the resulting royalty savings were discounted using a rate based on the overall weighted cost of capital of the Company as well as the asset specific risks of the intangible assets.

(11)Reflects the fair value adjustment to the right of use assets and lease liabilities. Upon application of fresh start accounting, we revalued its right-of-use assets and lease liabilities using the incremental borrowing rate applicable to the Company after emergence from bankruptcy and commensurate with its new capital structure. In addition, we decreased the right-of-use assets to recognize $4 million related to the unfavorable lease contracts.

(12)Reflects the fair value adjustment to adjust Long-term debt as of the Effective Date. This adjustment is to state our debt at estimated fair values.

(13)Reflects a remeasurement of pension and Other Postretirement Benefits related accounts as part of fresh start accounting considerations at emergence.

(14)Reflects the impact of fresh start adjustments on deferred taxes. We purchased the assets, including the stock of subsidiaries, of Frontier Communications Corporation (“Predecessor’s Parent”) at the time of emergence. The Predecessor’s Parent’s federal and state net operating loss carryforwards are expected to have been utilized as a result of the taxable gain realized upon emergence. To the extent not utilized to offset taxable gain, such net operating loss carryforwards are expected to be reduced in accordance with Section 108 of the U.S. Internal Revenue Code of 1986, as amended (the “Code”). As part of the taxable purchase, elections were made under Code section 338(h)(10) to step up the value of assets in certain subsidiaries to fair market value. All other subsidiaries carried over their deferred taxes. The adjustments reflect a $1.5 billion reduction in deferred tax assets for federal and state net operating loss carryforwards, a reduction in valuation allowance and a reduction in deferred tax liabilities.

(15)Reflects the cumulative impact of the fresh start adjustments as discussed above and the elimination of Predecessor accumulated earnings.

(16)Reflects the derecognition of accumulated other comprehensive loss.

Revenue Recognition [Abstract]  
Revenue Recognition (5) Revenue Recognition:

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

Data and Internet services include broadband services for consumer and business customers. We provide data transmission services to high volume business 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 business customers. Voice services also include the long-distance voice origination and termination services that we provide to our business customers and other carriers;

Video services include revenues generated from services provided directly to consumer customers as linear terrestrial television services, through various satellite providers, and through partnerships with over-the-top (OTT) video providers. Video services also includes pay-per-view revenues, video on demand, equipment rentals, and video advertising. We have made the strategic decision to limit sales of new traditional TV services focusing on our broadband products and OTT video options;

Other customer revenue includes switched access revenue, rents collected for collocation services, and revenue from other services and fees. Switched access revenue includes 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; and

Subsidy and other regulatory revenue includes revenues generated from cost subsidies from state and federal authorities, including the CAF II and RDOF.

As of April 30, 2021, the fair value of our net accounts receivable balances approximated their carrying values; therefore, no fair value adjustment for fresh start accounting was required. Our allowance for doubtful accounts decreased during the eight months ended December 31, 2021, primarily as a result of resolutions of carrier disputes.

We maintain an allowance for credit losses based on the estimated ability to collect accounts receivable. The allowance for credit losses is increased by recording an expense for the provision for bad debts for retail customers, and through decreases to revenue at the time of billing for wholesale customers. The allowance is decreased when customer accounts are written off, or when customers are given credits.

The provision for bad debts was $35 million for the year ended December 31, 2023, $26 million for the year ended December 31, 2022, $14 million for the four months ended April 30, 2021 and $14 million for the eight months ended December 31, 2021.

Approximately $143 million and $67 million of credits related to customers are included in other current liabilities on our consolidated balance sheets as of December 31, 2023, and December 31, 2022, respectively.

In accordance with ASC 326, we performed calculations to estimate expected credit losses, utilizing rates that are consistent with our write offs (net of recoveries) because such events affect the entity’s loss given default experience.

As of April 30, 2021, as a result of fresh start accounting, we have adjusted our property, plant, and equipment balance to fair value. See Note 4 for additional information. Property, plant, and equipment includes approximately $179 million and $121 million of fixed assets recognized under finance leases as of December 31, 2023 and 2022, respectively.

As of December 31, 2023, our materials and supplies were $594 million, as compared to $546 million as of December 31, 2022. This increase was primarily due to our fiber build plans and consumer premises equipment. Components of this include an increase in fiber, network electronics, and customer premises equipment.

During 2022, our materials and supplies increased by approximately $400 million, as compared to 2021. This increase was primarily due to our fiber build plans and consumer premises equipment.

In 2023, our capital expenditures were $3,211 million, which included a net decrease of $71 million due to changes in accounts payable and accrued liabilities, and vendor financing from December 31, 2022. As of December 31, 2023 there was $656 million in “accounts payable and accrued liabilities” and $255 million in vendor financing payables included in “other current liabilities” associated with capital expenditures. In 2023, we had capitalized interest of $83 million.

In 2023, we had asset sales and transactions of $63 million, including approximately $47 million in net proceeds related to certain wireless towers. Approximately $19 million of the proceeds related to wireless towers that qualified as sales, included in investing cash flows, and the remaining $28 million in proceeds related to wireless towers that were subject to sale-leaseback agreements and included in financing cash flows. After taking these sales and transactions into account, along with our capital expenditures, our net capital activity was $3,148 million as of December 31, 2023.

During 2022, we sold a property that was subject to leaseback, generating approximately $70 million in proceeds.

During 2021, we sold certain properties consisting of land and buildings for approximately $15 million in cash. The aggregate carrying value of the properties was approximately $14 million, resulting in a gain on the sale of $1 million, which, given our composite group method of accounting for depreciation, was recognized against “Accumulated Depreciation” in our consolidated balance sheet. We also sold certain properties subject to leaseback, generating $23 million in proceeds.

Depreciation expense is principally based on the composite group method. Depreciation expense was as follows:

Intangibles (8) Intangibles:

We consider 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. No impairment was present for either intangibles or property plant and equipment as of December 31, 2023, 2022, and 2021.

As a result of fresh start accounting, on the Effective Date, intangible assets and related accumulated amortization of the Predecessor were eliminated. Successor intangible assets were recorded at fair value as of the Effective Date. See Note 4.

Following the Effective Date, we amortize our intangible assets on a straight line basis, over the assigned useful lives of 16 years for our wholesale customer relationships, 11 years for our business customer relationships, and five years for our trademarks and tradenames. Amortization expense based on our current estimate of useful lives, is estimated to be approximately $321 million in 2024 and 2025, $301 million in 2026 and $291 million in 2027 and 2028.

For the Predecessor, amortization expense was primarily for our customer base acquired as a result of our acquisitions in 2010, 2014, and 2016 with each based on a useful life of 8 to 12 years and amortized on an accelerated method. Our trade name was an indefinite-lived intangible asset that was not subject to amortization.

Long-Term Debt [Abstract]  
Long-Term Debt (9) Long-Term Debt:

Chapter 11 Restructuring

The filing of the Chapter 11 Cases constituted an event of default that accelerated substantially all then-outstanding obligations under Old Frontier’s debt agreements and notes as follows:

the amended and restated credit agreement, dated as of February 27, 2017 (as amended, the JPM Credit Agreement);

the 8.000% first lien secured notes due April 1, 2027 (the Original First Lien Notes);

the 8.500% second lien secured notes due April 1, 2026 (the Original Second Lien Notes); and

the unsecured notes and debentures and the secured and unsecured debentures of our subsidiaries.

As of the Effective Date, amounts that were outstanding under the JPM Credit Agreement, the Original First Lien Notes, and the Original Second Lien Notes were repaid in full.

On the Effective Date, pursuant to the terms of the Plan, all of the obligations under Old Frontier’s unsecured senior note indentures were cancelled, and in connection with emergence, we issued 244,401,000 shares of common stock that were transferred to holders of the allowed senior notes claims (as defined under the Plan).

Interest expense for the four months ended April 30, 2021 recorded on our Predecessor statements of income was lower than contractual interest of $450 million because we ceased accruing interest on the Petition Date in accordance with the terms of the Plan and ASC Topic 852.

Credit Facilities and Term Loans

Revolving Facility

On March 8, 2023, Frontier Holdings entered into an amendment to its Revolving Facility, which, among other things, (i) extends the maturity with respect to the commitments of certain revolving lenders (in addition to certain amendments to springing maturity provisions); (2) amends the financial maintenance covenant for the benefit of the Revolving Facility by increasing the maximum first lien leverage ratio thereunder to 3.50:1.00, with step-downs to: (a) 3.25:1.00 in 2026; and (b) 3.00:1.00 in 2027 and continuing thereafter; and (3) provides for certain amendments to debt incurrence and other restrictive covenants.

The $900 million Revolving Facility will be available on a revolving basis until April 30, 2025 and with respect to certain lenders currently representing $850 million thereunder, the maturity date of the Revolving Facility will be the earliest of (a) April 30, 2028, (b) 91 days prior to the maturity date of the term loan facility, (c) unless such notes have been repaid and/or redeemed in full, the date that is 91 days prior to the stated maturity date of our 5.875% First Lien Notes due 2027, and (d) unless such notes have been repaid and/or redeemed in full, the date that is 91 days prior to the stated maturity date of our 5.000% First Lien Notes due 2028.

At Frontier’s election, the determination of interest rates for the Revolving Facility is based on margins over the alternate base rate or over Secured Overnight Financing Rate (“SOFR”). The interest rate margin with respect to any SOFR loan under the Revolving Facility is 3.50% or 2.50% with respect to any alternate base rate loans, with a 0% SOFR floor.

Subject to customary exceptions and thresholds, the security package under the Revolving Facility includes pledges of the equity interests in certain of our subsidiaries, which is currently limited to certain specified pledged entities and substantially all personal property of Frontier Video, which same assets also secure our First Lien Notes. The Revolving Facility is guaranteed by the same subsidiaries that guarantee the First Lien Notes. After giving effect to approximately $358 million of letters of credit previously outstanding, we have $542 million of available borrowing capacity under the Revolving Facility.

The Revolving Facility includes customary negative covenants for loan agreements of this type, including covenants limiting Frontier and our restricted subsidiaries’ (other than certain covenants therein which are limited to subsidiary guarantors) ability to, among other things, incur additional indebtedness, create liens on assets, make investments, loans or advances, engage in mergers, consolidations, sales of assets and acquisitions, pay dividends and distributions and make payments in respect of certain material payment subordinated indebtedness, in each case subject to customary exceptions for loan agreements of this type.

The Revolving Facility also includes certain customary representations and warranties, affirmative covenants, and events of default, including, but not limited to, payment defaults, breaches of representations and warranties, covenant defaults, certain events under ERISA, change of control or damage to a material portion of the collateral.

Term Loan Facility

The Term Loan Facility’s maturity date is October 8, 2027. At our election, the determination of interest rates for the Term Loan Facility is based on margins over adjusted Term SOFR or the alternate base rate. The interest rate margin under the Term Loan Facility is 3.75% with respect to any Term SOFR loan or 2.75% with respect to any alternate base rate loan, with a 0.75% Term SOFR floor.

Fiber Securitization Transaction

Secured Fiber Network Revenue Term Notes

On August 8, 2023, our limited-purpose, bankruptcy remote, subsidiary, Frontier Issuer, issued $1.6 billion aggregate principal amount of secured Fiber Term Notes, less $58 million in original issue discounts, consisting of $1.1 billion 6.60% Series 2023-1, Class A-2 term notes, $155 million 8.30% Series 2023-1, Class B term notes and $312 million 11.50% Series 2023-1, Class C term notes, each with an anticipated term ending in July 2028 (such anticipated repayment date, the “ARD”), in an offering exempt from registration under the Securities Act. We intend to use the proceeds from the offering of the Fiber Term Notes for, among other things, general corporate purposes, including potential investments or expenditures, such as capital expenditures and research and development, in line with our fiber expansion and copper migration strategies. In addition, we used a portion of the proceeds to retire and defease certain outstanding indebtedness of our subsidiary Frontier Southwest Incorporated.

The Fiber Term Notes were issued as part of a securitization transaction, pursuant to which the Company’s fiber network assets and associated customer contracts in certain neighborhoods in the Dallas, Texas metropolitan area were contributed to AssetCo, a direct, wholly-owned subsidiary of Frontier Issuer. The Fiber Term Notes are secured by these fiber assets and associated customer contracts. The assets of Frontier Issuer, AssetCo and the other securitization entities are available to satisfy only the obligations owed under the Fiber Term Notes and are not available to any other creditors of the Company or its affiliates. The Fiber Term Notes were issued pursuant to an indenture, dated as of August 8, 2023 (the “Base

Indenture”), as supplemented by the Series 2023-1 Supplement thereto, dated as of August 8, 2023 (the “Series 2023-1 Supplement”), in each case entered into by and among the Issuer, Frontier Dallas TX Fiber 1 LLC (“AssetCo”) and Citibank, N.A. as the indenture trustee (the “Trustee”).

The Base Indenture, together with the Series 2023-1 Supplement and Series 2023-2 Supplement, and any other series supplements to the Base Indenture, are referred to herein as the “Fiber Term Notes Indenture.”

(1) If Frontier Issuer has not repaid or refinanced any Fiber Term Note prior to the monthly payment date in July of 2028, additional interest will accrue thereon in an amount equal to the greater of (i) 5.00% per annum and (ii) the excess amount, if any, by which the sum of the following exceeds the interest rate for such note: (A) the yield to maturity (adjusted to a “mortgage-equivalent basis” pursuant to the standards and practices of the Securities Industry and Financial Markets Association) on the ARD for such note of the United States Treasury Security having a remaining term closest to 10 years plus (B) 5.00% plus (C) the post-ARD note spread applicable to such Note.

While the Fiber Term Notes are outstanding, scheduled payments of interest are required to be made on the Notes on a monthly basis. From and after the ARD, principal payments will also be required to be made on the Notes on a monthly basis. No principal payments will be due on the Fiber Term Notes prior to the ARD, unless certain rapid amortization or acceleration triggers are activated.

 

The Fiber Term Notes are subject to a series of covenants and restrictions customary for transactions of this type. These covenants and restrictions include (i) that Frontier Issuer maintains a liquidity reserve account to be used to make required payments in respect of the Notes, (ii) provisions relating to optional and mandatory prepayments, including specified make-whole payments in the case of certain optional prepayments of the Fiber Term Notes prior to the monthly payment date in July 2026, (iii) certain indemnification payments in the event, among other things, that  the transfers of the assets pledged as collateral for the Fiber Term Notes are in stated ways defective or ineffective and (iv) covenants relating to recordkeeping, access to information and similar matters. As provided in the Base Indenture, the Fiber Term Notes are also subject to rapid amortization in the event of a failure to maintain a stated debt service coverage ratio. A rapid amortization may be cured if the debt service coverage ratio exceeds a certain threshold for a certain period of time, upon which cure, regular amortization, if any, will resume. The Fiber Term Notes are also subject to certain customary events of default, including events relating to non-payment of required interest, principal or other amounts due on or with respect to the Fiber Term Notes, failure to comply with covenants within certain time frames, certain bankruptcy events, breaches of specified representations and warranties, failure of security interests to be effective and certain judgments.

Securitized Financing Facility

In connection with the Fiber Term Notes, Frontier Issuer entered into a financing facility for the issuance of up to $500 million in Series 2023-2 Secured Fiber Network Revenue Variable Funding Senior Notes, Class A-1 (the “Variable Funding Notes”).  Frontier Issuer had not drawn on the Variable Funding Notes as of December 31, 2023.

The Variable Funding Notes were issued pursuant to the Base Indenture, as supplemented by the Series 2023-1 Supplement and the Series 2023-2 Supplement, dated as of August 24, 2023 (the “Series 2023-2 Supplement”), in each case entered into by and among Frontier Issuer, AssetCo and the Trustee.

Drawings and certain additional terms related to the Variable Funding Notes are governed by the Class A-1 Note Purchase Agreement, dated as of August 24, 2023 (the “Variable Funding Note Purchase Agreement”), among Frontier Issuer, AssetCo, Frontier Communications Holdings, LLC (as the “Manager”), certain conduit investors, financial institutions and funding agents, and Barclays Bank plc, as administrative agent. The Variable Funding Notes will be governed, in part, by the Variable Funding Note Purchase Agreement and by certain generally applicable terms contained in the Indenture. The initial anticipated repayment date for the Variable Funding Notes is July 2026, and Frontier Issuer and Manager have the option to elect two one-year extensions of the anticipated repayment date. Following the initial anticipated repayment date (and any extensions thereof), additional interest will accrue on the Variable Funding Notes equal to 5.0% per annum.

Defeasance of Notes

During 2023, the Company extinguished $53 million of notes issued by its subsidiary Frontier Southwest Incorporated and transferred assets to an escrow account to pay the future interest and principal on the remaining $47 million of notes, which remain on the Company’s balance sheet as outstanding debt and restricted assets.

Other Obligations

During 2018, we contributed real estate properties with an aggregate fair value of $37 million for the purpose of funding a portion of our contribution obligations to our qualified defined benefit pension plan. The pension plan obtained independent appraisals of the property and, based on these appraisals, the pension plan recorded the contributions at aggregate fair value of $37 million for 2019. We entered into a lease for the contributed properties. The properties are managed on behalf of the pension plan by an independent fiduciary, and the terms of the lease were negotiated with the fiduciary on an arm’s-length basis.

For properties contributed in 2018, leases have initial terms of 20 years at a combined average aggregate annual rent of approximately $5 million.

The contribution and leaseback of the properties were treated as financing transactions and, accordingly, we continue to depreciate the carrying value of the property in our financial statements and no gain or loss was recognized. An obligation of $53 million is included in our consolidated balance sheet within “Other liabilities” as of December 31, 2023 and the liability is reduced annually by a portion of the lease payments made to the pension plan. Under the new lease standard, liabilities for these finance transactions are included in our financing lease liabilities. Refer to Note 11 for additional details.

Lessee

For lessee agreements, we elected to apply the short-term lease recognition exemption for all leases that qualify and as such, does not recognize assets or liabilities for leases with terms of less than twelve months, including existing leases at transition. We elected not to separate lease and non-lease components.

We have operating and finance leases for administrative and network properties, vehicles, and certain equipment. Our leases have remaining lease terms of 1 year to 83 years, some of which include options to extend the leases, and some of which include options to terminate the leases within 1 year.

Lessor

We are the lessor for operating leases of towers, datacenters, corporate offices, and certain equipment. Our leases have remaining lease terms of 1 year to 62 years, some of which include options to extend the leases, and some of which include options to terminate the leases within 1 year. None of these leases include options for our lessees to purchase the underlying asset.

A significant number of our service contracts with our customers include equipment rentals. We have elected to apply the practical expedient to account for those associated equipment rentals and services as a single, combined component. We have evaluated the service component to be ‘predominant’ in these contracts and have accounted for the combined component as a single performance obligation under ASC 606.

We, as a lessor, recognized revenue of $62 million for the year ended December 31, 2023, $63 million for the year ended December 31, 2022, $21 million for the four months ended April 30, 2021, $42 million for the eight months ended December 31, 2021.

During 2023, we amended the medical coverage for certain postretirement benefit plans, which resulted in remeasurement loses of $3 million, primarily due to discount rate changes. For the pension plan, we had a remeasurement gain of $202 million, primarily due to strong investment performance during 2023.

During 2022, we recorded an actuarial gain of $248 million as a result of remeasurements due to amendments in the medical coverage for certain postretirement benefit plans, discount rate changes, as well as regular period end remeasurements. As a result of pension settlement charges incurred during 2023, we had a remeasurement gain of $218 million, which included period end remeasurement. Refer to Note 19 for further details.

Pension and OPEB benefit (cost) consists of interest costs, expected return on plan assets, amortization of prior service (costs) and recognition of actuarial (gain) loss. Service cost components of pension and OPEB benefit costs are included in “Selling, general, and administrative expenses” on our consolidated statements of income.

(14) Stock Plans:

Upon emergence the Frontier Communications Parent, Inc. 2021 Management Incentive Plan (the “2021 Incentive Plan”) was approved and adopted by the Board. The 2021 Incentive Plan permits stock-based awards to be made to employees, directors, or consultants of the Company or its affiliates, as determined by the Compensation and Human Capital Committee of the Board. Under the 2021 Incentive Plan, 15,600,000 shares of common stock have been reserved for issuance. As of December 31, 2023, approximately 4,309,000 shares were available to grant under the Emergence LTI Program.

For purposes of determining compensation expense, the fair value of each restricted stock grant is estimated based on the closing price of our common stock on the date of grant. The non-vested restricted stock units granted in 2022 and 2023 generally vest, and are expensed, on a ratable basis over three years from the grant date of the award. Total remaining unrecognized compensation cost associated with unvested restricted stock awards that is deferred at December 31, 2023 was $36 million and the weighted average vesting period over which this cost is expected to be recognized is approximately 1 year.

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 $38 million and $34 million, for the years ended December 31, 2023, and 2022, respectively, has been recorded in connection with restricted stock.

Performance Stock Units

Under the 2021 Incentive Plan, a target number of performance units (“PSU”) are awarded to each participant with respect to the three year performance period (the “Measurement Period”). The performance metrics under the 2021 PSU awards consist of targets for (1) Adjusted Fiber EBITDA, (2) Fiber Locations Constructed and (3) Expansion Fiber Penetration. In addition, there is an overall relative total shareholder return (TSR)” modifier, which is based on our total return to stockholders over the Measurement Period relative to the S&P 400 Mid Cap Index. Each performance metric is weighted 33.3%, and targets for each metric are set for each of the three years during the Measurement Period. Achievement of the metrics will be measured separately, and the number of awards earned will be determined based on actual performance relative to the targets of each performance metric, plus the effect of the TSR modifier. Achievement is measured on a cumulative basis for each performance metric individually at the end of the three year Measurement Period. The payout of the 2021 PSUs can range from 0% to a maximum award payout of 300% of the target units. The payout of the 2022 PSUs can range from 0% to a maximum award payout of 200% of the target units. The payout of the 2023 PSUs can range from 0% to a maximum award payout of 200% of the target units.

The number of PSU awards earned at the end of the Measurement Period may be more or less than the number of target PSUs granted as a result of performance. An executive must maintain a satisfactory performance rating during the Measurement Period and, except for limited circumstances, must be employed by Frontier upon determination in order for the award to vest. The Compensation and Human Capital Committee will determine the number of shares earned for the Measurement Period in

the first quarter of the year following the end of the Measurement Period. PSUs awards, to the extent earned, will be paid out in the form of common stock on a one-for-one basis.

Under ASC 718, Stock Based Compensation Expense, a grant date, and the fair value of a performance award are determined once the targets are finalized. For the 2021, 2022 and 2023 PSU awards, targets for all of the metrics have been fully set for each performance period and the related expense will be amortized over the appropriate performance period.

(1) Represents the weighted average of the closing price of our stock on the date of the awards.

(2) Approximately 1.1 million shares included in this award were granted in 2021 with a grant date fair value of $30.85 per share. Approximately 2.1 million shares were granted in 2022 with a grant date fair value price of $27.22 per share.

(3) Approximately 0.2 million shares included in this award were granted in 2022 with a grant date fair value of $26.81 per share. Approximately 0.2 million shares have been granted as of December 31, 2023 with a grant date fair value of $23.95 per share.

For purposes of determining compensation expense, the fair value of each performance share grant is estimated based on the closing price of a share of our common stock on the date of the grant, adjusted to reflect the fair value of the relative TSR modifier. In 2023 and 2022, we recognized net compensation expense, reflected in “Selling, general, and administrative expenses,” of $69 million and $47 million, respectively related PSU awards.

Non-Employee Director Equity Compensation

Non-employee directors receive $250,000 of annual core compensation which includes $150,000 of RSUs granted annually. In both 2023 and 2022, we recognized $1 million in stock-based compensation expense related to non-employee director units.

In 2021, non-employee directors received an initial emergence RSU grant valued at $300,000. In addition, Board committee chairs receive retainers for their committee service in the form of RSUs. In 2021, we recognized $1 million in stock-based compensation expense related to non-employee director units.

Predecessor Plans - 2017 Equity Incentive Plan

Under the 2017 EIP, awards of our common stock were granted to eligible employees in the form of incentive stock options, non-qualified stock options, SARs, restricted stock, performance shares or other stock-based awards. No awards were granted more than 10 years after the effective date (May 10, 2017) of the 2017 EIP plan. The exercise price of stock options and SARs under the EIPs generally were equal to or greater than the fair market value of the underlying common stock on the date of grant. Stock options were not ordinarily exercisable on the date of grant but vested over a period of time (generally four years). Under the terms of the EIPs, subsequent stock dividends and stock splits had the effect of increasing the option shares outstanding, which correspondingly decreased the average exercise price of outstanding options.

Under ASC 740 – 270, income tax expense for the four months ended April 30, 2021, is based on the actual year to date effective tax rate for the first four months of the year inclusive of the impact of the fresh start and reorganization adjustments. Income tax expense for the eight months ended December 31, 2022 is based on the actual year to date effective tax rate for the successor period.

Other Tax Items

As of December 31, 2023, $8 million of expected income tax refunds are included in “Income taxes and other current assets” and $13 million of expected income tax receivable are included in “other assets” in the consolidated balance sheet.

In 2023, we paid net zero federal and state income tax. In 2022, we paid net federal and state income tax totaling $8 million. For the four months ended April 30, 2021 and the eight months ended December 31, 2021, we paid net federal and state income tax amounting to $9 million and $28 million, respectively.

The Company reviewed the requirements of the Corporate Alternative Minimum Tax under the Inflation Reduction Act and Notice 2023-7, and does not believe the Company is subject to this new tax.

Our federal net operating loss carryforward as of December 31, 2023, is estimated at $1.3 billion gross (tax effected $272 million). Some of the federal loss carryforward will begin to expire between 2036 and 2037, with $956 million gross (tax effected $201 million) carrying forward indefinitely, unless otherwise used.

Our state tax operating loss carryforward as of December 31, 2023, is estimated at $3.45 billion. A portion of our state loss carryforward will continue to expire annually through 2042, unless otherwise used.

Our federal research and development credit as of December 31, 2023, is estimated at $10 million. The federal research and development credit will begin to expire after 2041, unless otherwise used.

Our various state credits as of December 31, 2023, are estimated at $34 million. The state credits will begin to expire after 2024, unless otherwise used.

We considered positive and negative evidence in regard to evaluating certain deferred tax assets during 2023, including the development of recent years of pre-tax book losses. On the basis of this evaluation, a valuation allowance of $228 million tax effected ($180 million net of federal benefit) was recorded as of December 31, 2023.

This valuation allowance is related to state net operating losses, state tax credits, and the state impact from the federal limitation on interest expense deduction. In evaluating our ability to realize our deferred tax assets, management considers whether it is more likely than not that some or all of the deferred tax assets will not be realized. Management also considered the projected reversal of deferred tax liabilities in making this assessment. Based upon this assessment, management believes it is more likely than not we will realize the benefits of these deductible differences, net of valuation allowance.

The Inflation Reduction Act was signed into law on August 16, 2022. The law contains numerous changes to tax laws effective January 1, 2023. The Company evaluated the effects of the Inflation Reduction Act and does not believe there to be a material impact in 2023 or in the future.

The provision (benefit) for federal and state income taxes, as well as the taxes charged or credited to equity of Frontier, includes amounts both payable currently and deferred for payment in future periods as indicated below:

U.S. GAAP requires applying a “more likely than not” threshold to the recognition and derecognition of uncertain tax positions either taken or expected to be taken in our income tax returns. The total amount of our gross tax liability for tax positions that may not be sustained under a “more likely than not” threshold amounts to $5 million as of December 31, 2023, including immaterial interest. The amount of our uncertain tax positions, for which it is reasonably possible that the total amounts of unrecognized tax benefits will significantly increase or decrease during the next twelve months, would not have a material impact on our effective tax rate as of December 31, 2023.

Our policy regarding the classification of interest and penalties is to include these amounts as a component of income tax expense. This treatment of interest and penalties is consistent with prior periods. We are subject to income tax examinations generally for the years 2018 forward for federal and 2016 forward for state filing jurisdictions. We also maintain uncertain tax positions in various state jurisdictions.

The following table sets forth the changes in our balance of unrecognized tax benefits:

Retirement Plans [Abstract]  
Retirement Plans (19) Retirement Plans:

We sponsor a noncontributory defined benefit pension plan covering a significant number of our former and current employees and other postretirement benefit plans that provide medical, dental, life insurance and other benefits for covered retired employees and their beneficiaries and covered dependents. The pension plan and postretirement benefit plans are closed to the majority of our newly hired employees. The benefits are based on years of service and final average pay or career average pay. Contributions are made in amounts sufficient to meet ERISA funding requirements while considering tax deductibility. Plan assets are invested in a diversified portfolio of equity and fixed-income securities and alternative investments.

The accounting results for pension and other postretirement benefit costs and obligations are dependent upon various actuarial assumptions applied in the determination of such amounts. These actuarial assumptions include the following: discount rates, expected long-term rate of return on plan assets, future compensation increases, employee turnover, healthcare cost trend rates, expected retirement age, optional form of benefit and mortality. We review these assumptions for changes annually with our independent actuaries. We consider our discount rate and expected long-term rate of return on plan assets to be our most critical assumptions.

The discount rate is used to value, on a present value basis, our pension and other postretirement benefit obligations as of the balance sheet date. The same rate is also used in the interest cost component of the pension and postretirement benefit cost determination for the following year. The measurement date used in the selection of our discount rate is the balance sheet date. Our discount rate assumption is determined annually with assistance from our independent actuaries based on the pattern of expected future benefit payments and the prevailing rates available on long-term, high quality corporate bonds that approximate the benefit obligation.

As of December 31, 2023, 2022 and 2021, we utilized an estimation technique that is based upon a settlement model (Bond:Link) that permits us to closely match cash flows to the expected payments to participants. This rate can change from year-to-year based on market conditions that affect corporate bond yields.

As a result of the technique described above, we are utilizing a discount rate of 5.20% as of December 31, 2023 for our qualified pension plan, compared to rates of 5.50% and 2.90% in 2022 and 2021, respectively. The discount rate for postretirement plans as of December 31, 2023 was 5.20% compared to 5.50% in 2022 and 3.00% in 2021.

The expected long-term rate of return on plan assets is applied in the determination of periodic pension and postretirement benefit cost as a reduction in the computation of the expense. In developing the expected long-term rate of return assumption, we considered published surveys of expected market returns, 10 and 20 year actual returns of various major indices, and our own historical 5 year, 10 year and 20 year investment returns. The expected long-term rate of return on plan assets is based on an asset allocation assumption of 35% in long-duration fixed income securities, and 65% in equity securities and other investments. We review our asset allocation at least annually and make changes when considered appropriate. Our pension asset investment allocation decisions are made by the Retirement Investment & Administration Committee (RIAC), a committee comprised of members of management, pursuant to a delegation of authority by the Board of Directors. Asset allocation decisions take into account expected market return assumptions of various asset classes as well as expected pension benefit payment streams. When analyzing anticipated benefit payments, management considers both the absolute amount of the payments as well as the timing of such payments. Our expected long-term rate of return on plan assets was 7.50% in 2023 and 2022. For 2024, we expect to assume a rate of return of 7.50%. Our pension plan assets are valued at fair value as of the measurement date. The measurement date used to determine pension and other postretirement benefit measures for the pension plan and the postretirement benefit plan is December 31.

During 2023, we capitalized $18 million of pension and OPEB expense into the cost of our capital expenditures as the costs relate to our engineering and plant construction activities. During 2022, we capitalized $21 million of pension and OPEB expense into the cost of our capital expenditures as the costs relate to our engineering and plant construction activities. During the four months of April 30, 2021, and the eight months ended December 31, 2021, we capitalized $7 million and $15 million, respectively, of pension and OPEB expense.

The pension plan contains provisions that provide certain employees with the option of receiving a lump sum payment upon retirement. These payments are recorded 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 2023, lump sum pension payments to terminated or retired individuals amounted to $129 million. As we did not exceed the settlement threshold of $180 million, we did not recognize any non-cash settlement charges for 2023.

During 2023, we had actuarial gains of $44 million, driven by favorable lump sum conversion interest rates and cash balance interest crediting rates and updated census data to January 1, 2023, offset by a decrease of 30 basis points in the discount rate. Upon emergence from bankruptcy, Frontier revised its accounting policy to recognize actuarial gains and losses in the period in which they occur. As such, this gain was recorded in “Investment and other income, net” on our consolidated statements of income.

During 2022, lump sum pension settlement payments to terminated or retired individuals amounted to $200 million, which exceeded the settlement threshold of $175 million, and as a result, we recognized non-cash settlement charges totaling $55 million during the period. During 2022, we had actuarial gains of $867 million, driven by an increase of 260 basis points in the discount rate, favorable lump sum annuity conversion interest rates and cash balance interest crediting rates, and updated census data to January 1, 2022. Upon emergence from bankruptcy, Frontier revised its accounting policy to recognize actuarial gains and losses in the period in which they occur. As such, this gain was recorded in “Investment and other income, net” on our consolidated statements of income.

As part of fresh start accounting, we remeasured our net pension obligation as of April 30, 2021. In revaluing the pension benefit obligation, the assumed discount rate was 3.10% and the assumed rate of return on Plan assets was 7.50%. The discount rate increased compared to the 2.60% used in the December 31, 2020 valuation. This change as well as other changes in assumptions lead to a pension obligation decrease as a result of actuarial gains of $328 million.

The largest contributors to the $30 million actuarial loss from April 30, 2021 to December 31, 2021, were the decrease in the assumed discount rate from 3.10% to 2.90%.

We made pension plan contributions of $134 million and $176 million, in 2023 and 2022, respectively.

In 2021, we elected the provisions of American Rescue Plan Act, or ARPA retroactive to the 2019 plan year, which resulted in 1) a shortfall amortization period change from 7 to 15 years with a fresh start for the existing shortfall, commencing in the 2019 plan year and 2) interest rate stabilization, commencing in the 2020 plan year. These elections resulted in the creation of a funding balance that we used to satisfy certain required contributions in 2021. As a result of these changes, our pension plan contributions in the fiscal year 2021 were $42 million.

During 2023, we amended the medical coverage for certain postretirement benefit plans, which necessitated remeasurements of our OPEB obligations. These remeasurements along with the period end remeasurement resulted in the recognition of a net actuarial loss of $3 million, which was driven primarily from a higher assumed discount rate relative to the previous measurement dates, offset by updated census data to January 1, 2023.. Upon emergence from bankruptcy, we revised our accounting policy to recognize actuarial gains and losses in the period in which they occur. As such, this loss was recorded in “Investment and other income, net” on our consolidated statements of income. The remeasurements of our OPEB obligations during 2023 due to the amendments to the medical coverage for certain postretirement benefit plans also resulted in remeasurement of prior service credits of $45 million which were deferred in Accumulated comprehensive income as December 31, 2023.

During 2022, we amended the medical coverage for certain postretirement benefit plans, which necessitated remeasurements of our OPEB obligations. These remeasurements along with the period end remeasurement resulted in the recognition of a net actuarial gain of $248 million, which was driven primarily from a higher assumed discount rate relative to the previous measurement dates. Upon emergence from bankruptcy, we revised our accounting policy to recognize actuarial gains and losses in the period in which they occur. As such, this gain was recorded in “Investment and other income, net” on our consolidated statements of income. The remeasurements of our OPEB obligations during 2022 due to the amendments to the medical coverage for certain postretirement benefit plans also resulted in remeasurement of prior service credits of $40 million which were deferred in Accumulated comprehensive income as December 31, 2022.

As part of the fresh start accounting, we remeasured our net OPEB obligation as of April 30, 2021, resulting in actuarial gains of $99 million primarily driven by an increase in the discount rates used to measure our OPEB plans reduction when compared to December 31, 2020. The decrease in the discount rate from April 30, 2021 to December 31, 2021 primarily resulted in the actuarial loss of $37 million at December 31, 2021. During the eight months ended December 31, 2021, we amended the medical coverage for certain postretirement benefit plans, which resulted in remeasurements of our other postretirement benefit obligation and prior service credits of $79 million which were deferred in Accumulated comprehensive income as December 31, 2021.

401(k) Savings Plans

We sponsor employee retirement savings plans under section 401(k) of the Internal Revenue Code. The plans cover substantially all full-time employees. Under certain plans, we provide matching contributions. Employer contributions were $37 million in 2023, $38 million in 2022, $14 million for the four months ended April 30, 2021and $25 million for the eight months ended December 31, 2021, respectively.

Fair Value Of Financial Instruments [Abstract]  
Fair Value Of Financial Instruments (20) Fair Value of Financial Instruments:

Fair value is defined under GAAP as the exit price associated with the sale of an asset or transfer of a liability in an orderly transaction between market participants at the measurement date. Valuation techniques used to measure fair value under GAAP must maximize the use of observable inputs and minimize the use of unobservable inputs. In addition, GAAP establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value.

The three input levels in the hierarchy of fair value measurements are defined by the FASB generally as follows:

Input Level Description of Input

Level 1 Observable inputs such as quoted prices in active markets for identical assets.

Level 2 Inputs other than quoted prices in active markets that are either directly or indirectly observable.

Level 3 Unobservable inputs in which little or no market data exists.

Commitments And Contingencies [Abstract]  
Commitments And Contingencies (21) 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 connection with the fiber expansion build, we have prioritized diversifying our vendor base and solidifying partnership agreements with vendors for relevant labor and materials, to enable our build growth and customer expansion. Some of these key supplier agreements have multi-year terms and purchase commitments as we deem advisable in order to strengthen future supply.

In 2014, Citynet, a competitive local exchange carrier doing business in West Virginia, filed a qui tam action in federal court in the District Court for the Southern District of West Virginia against Frontier West Virginia, Inc. and others on behalf of the U.S. Government concerning billing practices relating to a government grant. The complaint became public in 2016 after the U.S. Government declined to participate in the case and instead allowed Citynet to pursue the claims on behalf of the U.S. On December 6, 2022, the parties reached a settlement in principle. On May 23, 2023, the parties finalized the terms of the settlement agreement to resolve the case in its entirety, the terms of which were made part of the public record and which requires a payment of approximately $18 million.

In addition, we are party to various legal proceedings (including individual actions, class and putative class actions, and governmental investigations) arising in the normal course of our business covering a wide range of matters and types of

claims including, but not limited to, general contract disputes, billing disputes, rights of access, taxes and surcharges, consumer protection, advertising, sales and the provision of services, intellectual property, including, trademark, copyright, and patent infringement, employment, regulatory, environmental, 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 material adverse effect on our financial position, results of operations, or cash flows.

Frontier has been named as a defendant in various intellectual property disputes. In each case, we have denied the allegations and are mounting a vigorous defense. We have accrued an amount for potential damages that we deem probable and reasonably estimable. We do not expect that any potential damages, if ultimately incurred, will be material.

In October 2013, the California Attorney General’s Office notified certain Verizon companies, including one of the subsidiaries that we acquired in the CTF transaction, 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 estimable, and we do not expect that any potential penalties, if ultimately incurred, will be material.

We accrue an expense for pending litigation when we determine that an unfavorable outcome is probable, and the amount of the loss can be reasonably estimated. Legal defense costs are expensed as incurred. None of our existing accruals for pending matters, after considering insurance coverage, is material. We monitor our pending litigation for the purpose of adjusting our accruals and revising our disclosures accordingly, when required. Litigation is, however, subject to uncertainty, and the outcome of any particular matter is not predictable. We will vigorously defend our interests in pending litigation, and as of this date, we believe that the ultimate resolution of all such matters, after considering insurance coverage or other indemnities to which we are entitled, will not have a material adverse effect on our consolidated financial position, results of operations, or our cash flows.

In 2015, Frontier accepted the FCC’s CAF Phase II offer, which provided $313 million in annual support through 2021 in our current 25 states in return for the Company’s commitment to make broadband available to households within the CAF II eligible areas. The Company was required to complete the CAF II deployment by December 31, 2021. Thereafter, the FCC has been reviewing carriers’ CAF II program completion data, and if the FCC determines that the Company did not satisfy applicable FCC CAF Phase II requirements, Frontier could be required to return a portion of the funds previously received and may be subject to certain fines, requirements and obligations.

On January 30, 2020, the FCC adopted an order establishing the RDOF competitive reverse auction to provide support to serve high-cost areas. Under the FCCs RDOF Phase I auction, we were awarded approximately $371 million over ten years to build gigabit-capable broadband over a fiber-to-the-premises network to approximately 127,000 locations in eight states (California, Connecticut, Florida, Illinois, New York, Pennsylvania, Texas, and West Virginia). We began receiving RDOF funding in the second quarter of 2022 and we will be required to complete the buildout to the awarded locations by December 31, 2028, with interim target milestones over this period. To the extent Frontier is unable to meet the milestones or construct to all locations by the required deadlines, Frontier could be required to return a portion of funds previously received and may be subject to certain fines, requirements and obligations.

The FCC currently classifies fixed consumer broadband services as information services, subject to light-touch regulation. In October 2023 the FCC released a notice of proposed rulemaking seeking to reclassify certain broadband services as lightly regulated telecommunications services imposing certain network neutrality requirements on the reclassified internet services. At this time, it remains uncertain whether the FCC will adopt these new network neutrality regulations and what impact that may have on Frontier’s business.

On November 15, 2021, President Biden signed the Infrastructure Investment and Jobs Act (IIJA) into law. The legislation appropriated funding for the establishment of the Affordable Connectivity Program (ACP), and FCC-administered monthly, low-income broadband benefit program. The ACP provides qualified customers up to $30 dollars per month (or $75 dollars per month for those on Tribal lands) to assist with their internet bill. Frontier is a participating provider in the ACP program. Absent additional funding, at present pace, the ACP funds are projected by the FCC to exhaust in April of 2024.

We conduct certain of our operations in leased premises and lease certain equipment and other assets pursuant to operating leases. The lease arrangements have terms ranging from 1 to 99 years and several contain rent escalation clauses providing for increases in monthly rent at specific intervals. When rent escalation clauses exist, we record annual rental expense based on the total expected rent payments on a straight-line basis over the lease term. Certain leases also have renewal options. Renewal options that are reasonably assured are included in determining the lease term.


As of December 31, 2023, we had total “Accounts payable and accrued liabilities” of $1.1 billion, of which $857 million is related to accounts payable. As of December 31, 2022, we had total “Accounts payable and accrued liabilities” of $1.4 billion, of which $1.2 billion is related to accounts payable.

We have negotiated favorable payment terms with some of our vendors that allow for a longer payment period than our normal customary terms (referred to as vendor financing), which are excluded from capital expenditures and reported as financing activities on the statement of cash flows. As of December 31, 2023, we had $263 million of vendor financing liabilities included in “Other current liabilities” on our consolidated balance sheets, of which $255 million is associated with capital expenditures. For the year ended December 31, 2023 we have made $5 million in vendor financing payments, of which $4 million is related to capital expenditures and $1 million is related to operating expenses.

We are party to contracts with several unrelated long-distance carriers. The contracts provide fees based on traffic they carry for us subject to minimum monthly fees.

At December 31, 2023, the estimated future payments for obligations under our noncancelable long-distance contracts and joint pole and communications service agreements are as follows:

CNA serves as our insurance carrier with respect to casualty claims (auto liability, general liability, and workers’ compensation) with dates of loss prior to June 1, 2017 (except for those claims which arise out of the operations acquired from CTF that have dates of loss prior to April 1, 2016). As our insurance carrier, they administer the casualty claims and make claim payments on our behalf. We reimburse CNA for such services upon presentation of their invoice. To serve as our carrier and make payments on our behalf, CNA requires that we establish a letter of credit in their favor. CNA could potentially draw against this if we failed to reimburse CNA in accordance with the terms of our agreement. The amount of the letter of credit is reviewed annually and adjusted based on claims history.

Zurich serves as our insurance carrier with respect to casualty claims (auto liability, general liability, and workers’ compensation) with dates of loss from June 1, 2017 and going forward. As our insurance carrier, they administer the casualty claims and make claim payments on our behalf. We reimburse Zurich for such services upon presentation of their invoice. To serve as our carrier and make payments on our behalf, Zurich requires that we establish letters of credit in their favor. Zurich could potentially draw against these letters of credit if we failed to reimburse Zurich in accordance with the terms of our agreement. The amount of the letters of credit is reviewed annually and adjusted based on claims history.

AIG Insurance serves as our insurance carrier with respect to casualty claims (auto liability, general liability, and workers’ compensation) that were acquired from CTF, as well as new claims which arise out of the operations acquired from CTF that have dates of loss prior to April 1, 2016. Sedgwick, a third-party claims administrator, administers the casualty claims and makes claim payments on our behalf. We reimburse Sedgwick for such services upon presentation of their invoice. However, to serve as our insurance carrier, AIG Insurance requires that we establish a letter of credit in their favor. AIG Insurance could potentially draw against this letter of credit if we failed to meet the insurance-related and claims-related obligations we assumed in accordance with the terms of our agreement. The amount of the letter of credit is reviewed annually and adjusted based on claims history.

Description Of Business And Summary Of Significant Accounting Policies [Abstract]  
Description Of Business (a)Description of Business:

Frontier Communications Parent, Inc. is a provider of communications services in the United States, with approximately 2.9 million broadband subscribers and approximately 13,300 employees, operating in 25 states. We were incorporated in 1935, originally under the name of Citizens Utilities Company and was known as Citizens Communications Company until July 31, 2008. Frontier and its subsidiaries are referred to as “we,” “us,” “our,” “Frontier,” or the “Company” in this report.

Basis Of Presentation And Use Of Estimates (b)Basis of Presentation and Use of Estimates:

Our consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (GAAP). Certain reclassifications of amounts previously reported have been made to conform to the current presentation. The consolidated financial statements include the accounts of Frontier Communications Parent, Inc., all consolidated subsidiaries and variable interest entities of which the Company is the primary beneficiary. All significant intercompany balances and transactions have been eliminated in consolidation.

In 2021, we recategorized our previous operating expenses categories (“Network access expenses” and “Network related expense”) into one expense line: “Cost of service”. All historical periods presented have been updated to conform to the new categorization. In addition, certain reclassifications of prior period balances have been made to conform to the current period presentation. For our financial statements as of and for the period ended December 31, 2023, we evaluated subsequent events and transactions for potential recognition or disclosure through the date that we filed this Form 10-K with the Securities and Exchange Commission (SEC).

The preparation of our 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 application of fresh start accounting, allowance for credit losses, asset impairments, indefinite-lived intangibles, depreciation and amortization, income taxes, and pension and other postretirement benefits, among others. For information about our use of estimates as a result of fresh start accounting, see Note 4.

Chapter 11 Bankruptcy Emergence

On April 14, 2020 (the “Petition Date”), Frontier Communications Corporation, a Delaware corporation (“Old Frontier”), and its subsidiaries (collectively with Old Frontier, the “Debtors”), commenced cases under chapter 11 (the “Chapter 11 Cases”) of title 11 of the United States Code (the “Bankruptcy Code”) in the U.S. Bankruptcy Court for the Southern District of New York (the “Bankruptcy Court”). On August 27, 2020, the Bankruptcy Court confirmed the Fifth Amended Joint Plan of Reorganization of Frontier Communications Corporation and its Debtor Affiliates Pursuant to Chapter 11 of the Bankruptcy Code (the “Plan” or the “Plan of Reorganization”), which was filed with the Bankruptcy Court on August 21, 2020, and on April 30, 2021 (the “Effective Date”), the Debtors satisfied the conditions precedent to consummation of the Plan as set forth in the Plan, and the Debtors emerged from the Chapter 11 Cases without any need for further action or order of the Bankruptcy Court. See Note 3 for additional information related to our emergence from Chapter 11 Cases.

Fresh Start Accounting

Upon emergence from bankruptcy, we adopted fresh start accounting in accordance with Accounting Standards Codification (ASC) Topic 852 – Reorganizations (ASC 852) and became a new entity for financial reporting purposes. As a result, the consolidated financial statements after the Effective Date are not comparable with the consolidated financial statements on or before that date as indicated by the “black line” division in the financial statements and footnote tables, which emphasizes the lack of comparability between amounts presented. References to “Successor” relate to our financial position and results of operations after the Effective Date. References to “Predecessor” refer to the financial position and results of operations of Old Frontier and its subsidiaries on or before the Effective Date. See Note 4 for additional information related to fresh start accounting.

During the Predecessor period, ASC 852 was applied in preparing the consolidated financial statements. ASC 852 requires the financial statements, for periods subsequent to the commencement of the Chapter 11 Cases, to distinguish transactions and events that are directly associated with the reorganization from the ongoing operations of the business. ASC 852 requires certain additional reporting for financial statements prepared between the bankruptcy filing date and the date of emergence from bankruptcy, including: (i) Reclassification of pre-petition liabilities that are unsecured, under-secured or where it cannot be determined that the liabilities are fully secured, to a separate line item on the consolidated balance sheet called, "Liabilities subject to compromise"; and (ii) Segregation of “Reorganization items, net” as a separate line on the consolidated statements of comprehensive loss, included within income from continuing operations.

Upon application of fresh start accounting, we allocated the reorganization value to our individual assets and liabilities, except for deferred income taxes, based on their estimated fair values in conformity with ASC Topic 805, Business Combinations. The amount of deferred taxes was determined in accordance with ASC Topic 740, Income Taxes. The Effective Date fair values of our assets and liabilities differed materially from their recorded values as reflected on the historical balance sheets, see Note 4.

Changes In Accounting Policies (c) Changes in Accounting Policies:

The accounting policy differences between Predecessor and Successor include:

Universal Service Fund and Other Surcharges - We collect various taxes, Universal Service Fund (USF) surcharges (primarily federal USF), and certain other taxes, from its customers and subsequently remit them to governmental authorities. The Predecessor recorded USF and other taxes on a gross basis on the consolidated statement of income, included within “Revenue” and “Cost of service expense”. After emergence, the Successor records these USF and other taxes on a net basis.

Provision for Bad Debt - The Predecessor reported the provision for bad debt as a reduction of revenue. After emergence, the Successor reports bad debt expense as an operating expense included in “Selling, general, and administrative expenses”.

Contract Acquisition Costs - During the Predecessor period, certain commissions to obtain new customers were deferred and amortized over four years, which represented the estimated customer contract period. As a result of fresh start accounting, that assumption was reevaluated and the period of benefit for our retail customers was determined to be less than one year. As such, these costs are now expensed as incurred.

Actuarial Losses on Defined Benefit Plans - Historically, actuarial gains (losses) were recognized as they occurred and included in “Accumulated other comprehensive income (loss)” and were subject to amortization over the estimated average remaining service period of participants. As part of fresh start accounting, we have made an accounting policy election to recognize these gains and losses immediately in the period they occur as Investment and other income (loss) on the consolidated statement of income.

Government Grants Revenue - Certain governmental grants that were historically presented on a net basis as part of capital expenditures, are now presented on a gross basis and included in ”Revenue” on the consolidated statement of income.

Administrative Expenses - Historically, the Predecessor capitalized certain administrative expenses, that following emergence, are expensed during the period incurred and included in “Selling, general, and administrative expense” on the consolidated statement of income.

Going Concern (d) Going Concern:

In accordance with the requirements of Accounting Standards Update (“ASU”) 2014-15, “Presentation of Financial Statements Going Concern (ASU 2014-15)”, and ASC 205, “Presentation of Financial Statements”, we have the responsibility to evaluate at each reporting period, including interim periods, whether conditions and/or events raise substantial doubt about the Company’s ability to meet its future financial obligations. In its evaluation for this report, management considered our current financial condition and liquidity sources, including current funds available, forecasted future cash flows and our conditional and unconditional obligations due within one year following the date of issuance of this Annual Report on Form 10-K.

Accordingly, the accompanying consolidated financial statements have been prepared assuming that we will continue as a going concern and contemplate the realization of assets and the satisfaction of liabilities in the normal course business.

Cash Equivalents And Restricted Cash (e)Cash Equivalents and Restricted Cash:

We consider all liquid investments with an original maturity of three months or less to be cash equivalents. Restricted cash amounts represent cash collateral required for certain Letter of Credit obligations and utility vendors and collateral for debt arrangements.

At December 31, 2023, the Company had $114 million in restricted cash. Pursuant to the terms of the Company’s securitized financing facility and secured fiber network revenue term notes, as described in Note 9, restricted cash is held in securitization escrow accounts. As of December 31, 2023, approximately $42 million is current restricted cash held for the purpose of paying interest and certain fees. In addition, as of December 31, 2023, approximately $72 million

is noncurrent restricted cash held for the purpose of satisfying the required liquidity reserve amount. We did not have any restricted cash as of December 31, 2022.
Short-Term Investments (f) Short-Term Investments:

Given the long-term nature of our fiber build, we have invested cash into short-term investments to improve interest income while preserving funding flexibility.

As of December 31, 2023, short-term investments of $1,075 million are comprised of term deposits earning interest in excess of traditional bank deposit rates, maturing between January 4, 2024, and May 2, 2024, and placed with banks with A-1/P-1 or equivalent credit quality. These short-term investments are in scope of ASC 320, Investments - Debt Securities. The short-term investments’ original maturity is greater than 90 days but less than one year, and they are classified as held to maturity, recorded as current assets, and are accounted for at amortized cost.

Other Investments

In connection with the closing of the securitization transaction, approximately $63 million in the form of U.S. Treasuries was deposited in an escrow account established with a trustee, for the purpose of paying interest and principal on $47 million in remaining debt of our subsidiary Frontier Southwest Incorporated. This balance is included in “Other assets” on our consolidated balance sheets and is restricted. See Note 9 for further details.

Revenue Recognition (g)Revenue Recognition:

Revenue for data and Internet services, voice services, video services and switched and non-switched access services is recognized as services are provided to customers. Services that are billed in advance include monthly recurring network access services (including data services), special access services, and monthly recurring voice, video, and related charges. Revenue is recognized by measuring progress toward the complete satisfaction of our performance obligations. The unearned portion of these fees is deferred as a component of “Advanced billings” on our consolidated balance sheet and recognized as revenue over the period that the services are provided. Services that are billed in arrears include 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 income and accrued in “Accounts receivable” on our consolidated balance sheet in the period that services are provided. Excise taxes are recognized as a liability when billed.

Satisfaction of Performance Obligations

We satisfy our obligations to customers by transferring goods and services in exchange for consideration received from the customer. The timing of our satisfaction of the performance obligation may differ from the timing of the customer’s payment.

Bundled Service and Allocation of Discounts

When customers purchase more than one service, revenue for each is determined by allocating the total transaction price based upon the relative stand-alone selling price of each service. We frequently offer service discounts as an incentive to customers, which reduce the total transaction price. Any incentives which are considered cash equivalents (e.g. gift cards) that are granted will similarly result in a reduction of the total transaction price. Cash equivalent incentives are accounted for on a portfolio basis and are recognized in the month they are awarded to customers.

Customer Incentives

In the process of acquiring and/or retaining customers, we may issue a variety of incentives aside from service discounts or cash equivalent incentives. Those incentives that have stand-alone value (e.g. gift cards not considered cash equivalents or free goods/services) are considered separate performance obligations. While these incentives are free to the customer, a portion of the consideration received from the customer is ascribed to them based upon their relative stand-alone selling price. These types of incentives are accounted for on a portfolio basis with both revenue and expense recognized in the month they are awarded to the customer. The earned revenue associated with these incentives is reflected in “Other” revenue while the associated costs are reflected in “Cost of Services”.

Upfront Fees

All non-refundable upfront fees assessed to our customers provide them with a material right to renew; therefore, they are deferred by creating a contract liability and amortized into “Data and Internet service revenue” for fees charged to our wholesale customers and “Other revenue” for fees charged to all other customers over the average customer life using a portfolio approach.

Customer Acquisition Costs

Sales commission expenses are recognized as incurred. According to ASC 606, incremental costs in obtaining a contract with a customer are deferred and recorded as a contract asset if the period of benefit is expected to be greater

than one year. For our retail customers, this period of benefit has been determined to be less than one year. As such, we applied the practical expedient that allows such costs to be expensed as incurred.

Taxes, Surcharges and Subsidies

We collect various taxes, Universal Service Funds (USF) surcharges (primarily federal USF), and certain other surcharges from our customers and subsequently remits these taxes to governmental authorities. During the predecessor period, USF and other surcharges amounted to $83 million during the four months ended April 30, 2021.

In June 2015, we accepted the FCC offer of support to price cap carriers under the Connect America Fund (“CAF”) Phase II program, which was intended to provide long-term support for broadband build commitments in high cost unserved or underserved areas. We recognized the FCC’s CAF Phase II subsidies into revenue on a straight-line basis over the seven-year funding term which ended on December 31, 2021. The FCC is reviewing carriers’ CAF II program completion data, and if the FCC determines that we did not satisfy certain applicable CAF Phase II requirements, we could be required to return a portion of the funds previously received and may be subject to certain other penalties, requirements and obligations. We have accrued an amount for any potential shortfall in the household build commitment 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 May 2022, we accepted the FCC offer under the Rural Digital Opportunity Fund (“RDOF”) Phase I program, which provides funding over a ten-year period to support the construction of broadband networks in rural communities across the country. We accepted $37 million in annual support through 2032 in return for our commitment to make broadband available to households within the RDOF eligible areas. We will recognize the FCC’s RDOF Phase I subsidies into revenue on a straight-line basis over the ten-year funding term which will end March 31, 2032. We are required to complete the RDOF deployment by December 31, 2028. Thereafter, the FCC will review carriers’ RDOF program completion data, and if the FCC determines that we did not satisfy applicable FCC RDOF requirements, we could be required to return a portion of the funds previously received and may be subject to certain other penalties, requirements and obligations. We accrue for any potential shortfall in the household build commitment that we deem to be probable and reasonably estimated.

Property, Plant And Equipment (h)Property, Plant and Equipment:

Property, plant, and equipment are stated at original cost, including capitalized interest, or fair market value as of the date of acquisition for acquired properties. Maintenance and repairs are charged to operating expenses as incurred. The gross book value of routine property, plant and equipment retirements is charged against accumulated depreciation.

Definite And Indefinite Lived Intangible Assets (i)Definite and Indefinite Lived Intangible Assets:Intangible assets are initially recorded at estimated fair value. Old Frontier historically amortized its acquired customer lists and certain other finite-lived intangible assets over their estimated useful lives on an accelerated basis. Upon emergence from bankruptcy, customer relationship intangibles were established for business and wholesale customers. These intangibles are amortized on a straight-line basis over their assigned useful lives of between 11 and 16 years. Additionally, trademark and tradename assets established upon emergence are amortized on a straight-line basis over 5 years. We review such intangible assets annually, or more often if indicators of impairment arise, to determine whether there is evidence that indicates an impairment condition may exist that would necessitate a change in useful life and a different amortization period
Impairment Of Long-Lived Assets And Long-Lived Assets To Be Disposed Of

(j)Impairment of Long-Lived Assets and Long-Lived Assets to Be Disposed Of:

We review long-lived assets to be held and used, including customer lists and property, plant and equipment, and long-lived assets to be disposed of for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. Recoverability of assets to be held and used is measured by comparing the carrying amount of the asset to the future undiscounted net cash flows expected to be generated by the asset. Recoverability of assets held for sale is measured by comparing the carrying amount of the assets to their estimated fair market value. If any assets are considered to be impaired, the impairment is measured by the amount by which the carrying amount of the assets exceeds the estimated fair value. Also, we periodically reassess the useful lives of our long-lived assets to determine whether any changes are required.

Lease Accounting (k)Lease Accounting:

We determine if an arrangement contains a lease at inception. Right-of-use (ROU) assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Operating and Finance lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. The operating and finance lease ROU asset also includes any lease payments made and excludes lease incentives. Our lease terms used in accounting for leases may reflect options to extend or terminate the lease when it is reasonably certain that we will exercise that option. Lease expense for operating leases is recognized on a straight-line

basis over the lease term. ROU assets for operating leases are recorded to “Other Assets”, and the related liabilities recorded to “Other current liabilities”, and “Other liabilities” on our consolidated balance sheets. Assets subject to finance leases are included in “Property, Plant & Equipment”, with corresponding liabilities recorded to “Other current liabilities”, and “Other liabilities” on our consolidated balance sheets.

We assess potential impairments to our leases annually, or as indicators exist, if indicators of impairment arise to determine whether there is evidence that indicate an impairment condition may exist. We continue to review our real estate portfolio and, during the first quarter of 2022, determined to either terminate or market for sublease certain facilities leases, which triggered an impairment of $44 million for our finance and operating lease assets recorded as restructuring charges and other costs. See Note 11 for further details.

Income Taxes And Deferred Income Taxes (l)Income Taxes and Deferred Income Taxes:

We file a consolidated federal income tax return. We utilize the asset and liability method of accounting for income taxes. Under the asset and liability method, deferred income taxes are recorded for the tax effect of temporary differences between the financial statement basis and the tax basis of assets and liabilities using tax rates expected to be in effect when the temporary differences are expected to reverse.

We recognize deferred tax assets to the extent that we believe that these assets are more likely than not to be realized. In making such a determination, we consider all available positive and negative evidence, including future reversals of existing taxable temporary differences, tax-planning strategies, and results of recent operations. If we determine that we are not able to realize a portion of our net deferred tax assets in the future, we would make an adjustment to the deferred tax asset valuation allowance, which would increase the provision for income taxes.

The tax effect of a change in tax law or rates included in income tax expense from continuing operations includes effect of changes in deferred tax assets and liabilities initially recognized through a charge or credit to other comprehensive income (loss). The residual tax effects typically are released when the item giving rise to the tax effect is disposed of, liquidated, or terminated.

Stock Plans

(m) Stock Plans:

We have one stock-based compensation plan under which grants are made and awards remain outstanding. Awards under this plan may be made to employees, directors or consultants of the Company or its affiliates, as determined by the Compensation and Human Capital Committee of the Board. Awards may be made in the form of restricted stock, restricted stock units, incentive stock options, non-qualified stock options, stock appreciation rights or other stock-based awards, including awards with performance, market, and time-vesting conditions.

The compensation cost recognized is based on awards ultimately expected to vest. GAAP requires forfeitures to be estimated and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates.

Recent Accounting Pronouncements Adopted And Not Yet Adopted Financial Accounting Standards Adopted During 2023

During the year ended December 31, 2023, we adopted, the Financial Accounting Standards Board’s (FASB) Accounting Standards Update (ASU) No. 2022-04, “Liabilities – Supplier Finance Programs (Subtopic 405-50): Disclosure of Supplier Finance Program Obligations” (ASU 2022-04), which establishes interim and annual reporting disclosure requirements about a company’s supplier finance programs for its purchase of goods and services. In the year of adoption, the disclosure of payment and other key terms under the programs and outstanding balances under the obligations also applies to interim reporting dates. As of December 31, 2023, we had $263 million of vendor financing liabilities included in “Other current liabilities” on our consolidated balance sheets. Refer to Note 21 for further details.

Financial Accounting Standards Not Yet Adopted

ASU No. 2023-09 – Income Taxes (Topic 740): Improvements to Income Tax Disclosures. The amendments in this Update require that public business entities on an annual basis (1) disclose specific categories in the rate reconciliation and (2) provide additional information for reconciling items that meet a quantitative threshold (if the effect of those reconciling items is equal to or greater than 5 percent of the amount computed by multiplying pretax income [or loss] by the applicable statutory income tax rate). For public business entities, the amendments in this Update are effective for annual periods beginning after December 15, 2024.

ASU No. 2023-07 – Segment Reporting (Topic 280): Improvements to reportable segment disclosures. The amendments in this update improve financial reporting by requiring disclosure of incremental segment information on an annual and

interim basis for all public entities to enable investors to develop more decision-useful financial analyses. Currently, Topic 280 requires that a public entity disclose certain information about its reportable segments. For example, a public entity is required to report a measure of segment profit or loss that the CODM uses to assess segment performance and make decisions about allocating resources. Topic 280 also requires other specified segment items and amounts, such as depreciation, amortization, and depletion expense, to be disclosed under certain circumstances. The amendments in this update do not change or remove those disclosure requirements. The amendments in this update also do not change how a public entity identifies its operating segments, aggregates those operating segments, or applies the quantitative thresholds to determine its reportable segments. The amendments in this update are effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted.

Fresh Start Adjustments

In accordance with the application of fresh start accounting, the following adjustments were made:

(8)Reflects unamortized deferred commissions paid to acquire new customers that are eliminated upon emergence as this is not a probable future benefit for the Successor. Costs to obtain customers have been reflected as part of intangible assets. Adjustment also reflects the elimination of certain contract assets and contract liabilities.

(9)Property Plant & Equipment – Reflects the decrease in net book value of property and equipment to the estimated fair value as of the Effective Date.

Personal property valued consisted of outside and inside plant network equipment, computers and software, vehicles, office furniture, fixtures and equipment, computers and software, and construction-in-progress. The fair value of our personal property was estimated using the cost approach, while the income approach was considered to assess economic sufficiency to support asset values. As a part of the valuation process, the third-party advisors’ diligence procedures included using internal data to identify and value assets.

Real property valued consisted of land, buildings, and leasehold improvements. The fair value was estimated using the cost approach and sales comparison (market) approach, with consideration of economic sufficiency to support certain asset values.

The following table summarizes the components of property and equipment, net as of April 30, 2021, and the fair value as of the Effective Date:

(10)Reflects the fair value adjustment to recognize trademark, trade name and customer relationship.

For purposes of estimating the fair values of customer relationships, we utilized an Income Approach, specifically, the Multi-Period Excess Earnings method, or MPEEM. The MPEEM estimates fair value based on the present value of the incremental after-tax cash flows attributable only to the subject intangible assets after deducting contributory asset charges. The cash flows attributable to the customer relationships were adjusted for contributory asset charges related to the working capital, fixed assets, trade name/trademarks and assembled workforce. The discount rate utilized to present-value the after-tax cash flows was based on the overall weighted cost of capital of the Company as well as the asset specific risks of the intangible assets. Changes in these inputs could have a significant impact on the fair value of the customer relationships intangible assets.

For purposes of estimating the fair value of trademarks and tradenames, an Income approach was used, specifically, the Relief from Royalty Method. The estimated royalty rates were historical third-party transactions regarding the licensing of similar type of assets as well as a review of historical assumptions used in prior transactions. The selected royalty rates were applied to the revenue generated by the trademarks and tradenames to determine the amount of royalty payments saved as a result of owning these assets. The forecasted cash flows were based on our projected revenues and the resulting royalty savings were discounted using a rate based on the overall weighted cost of capital of the Company as well as the asset specific risks of the intangible assets.

(11)Reflects the fair value adjustment to the right of use assets and lease liabilities. Upon application of fresh start accounting, we revalued its right-of-use assets and lease liabilities using the incremental borrowing rate applicable to the Company after emergence from bankruptcy and commensurate with its new capital structure. In addition, we decreased the right-of-use assets to recognize $4 million related to the unfavorable lease contracts.

(12)Reflects the fair value adjustment to adjust Long-term debt as of the Effective Date. This adjustment is to state our debt at estimated fair values.

(13)Reflects a remeasurement of pension and Other Postretirement Benefits related accounts as part of fresh start accounting considerations at emergence.

(14)Reflects the impact of fresh start adjustments on deferred taxes. We purchased the assets, including the stock of subsidiaries, of Frontier Communications Corporation (“Predecessor’s Parent”) at the time of emergence. The Predecessor’s Parent’s federal and state net operating loss carryforwards are expected to have been utilized as a result of the taxable gain realized upon emergence. To the extent not utilized to offset taxable gain, such net operating loss carryforwards are expected to be reduced in accordance with Section 108 of the U.S. Internal Revenue Code of 1986, as amended (the “Code”). As part of the taxable purchase, elections were made under Code section 338(h)(10) to step up the value of assets in certain subsidiaries to fair market value. All other subsidiaries carried over their deferred taxes. The adjustments reflect a $1.5 billion reduction in deferred tax assets for federal and state net operating loss carryforwards, a reduction in valuation allowance and a reduction in deferred tax liabilities.

(15)Reflects the cumulative impact of the fresh start adjustments as discussed above and the elimination of Predecessor accumulated earnings.

(16)Reflects the derecognition of accumulated other comprehensive loss.
