Footnotes to Consolidated Financial Highlights

1.              During the first quarter of 2013, the Company recognized a $256.7 million non-cash impairment charge to goodwill related to its Business Services reporting unit, of which $255.6 million is included in continuing operations and $1.1 million is reflected in discontinued operations. The impairment was based on an analysis of a number of factors after a decline in the Company’s market capitalization following the announcement of its fourth quarter 2012 earnings and 2013 financial guidance. The primary factor contributing to the impairment was a change in the discount rate and market multiples as a result of the change in these market conditions, both key assumptions used in the determination of fair value.

2.              Restructuring, acquisition and integration-related costs consisted of the following for the periods presented (in thousands):

Restructuring, acquisition and integration-related costs consist of costs related to restructuring, acquisition and integration-related activities. Such costs include: 1) integration-related costs, such as system conversion, rebranding costs and integration-related consulting and employee costs; 2) severance, retention and other employee termination costs associated with acquisition and integration activities and with certain voluntary employee separations; 3) transaction-related costs, which are direct costs incurred to effect a business combination, such as advisory, legal, accounting, valuation and other professional fees; and 4) facility-related costs, such as lease termination and asset impairments. The Company expects to incur restructuring, acquisition and integration-related costs of approximately $7 million in the first quarter of 2014 and $17 million for the full year 2014. The Company expects these costs to generally decline throughout the year.

3.              The income tax provision for the three and twelve months ended December 31, 2013, includes a $266.3 million non-cash charge to record a valuation allowance against the Company’s deferred tax assets. During the fourth quarter of 2013, the Company determined it will not be able to fully realize its deferred tax assets in the future.

4.              The operating results of the Company’s telecom systems business acquired as part of ITC^DeltaCom have been separately presented as discontinued operations for all periods presented. On August 2, 2013, the Company sold its ITC^DeltaCom telecom systems business. The Company has no significant continuing involvement in the operations or significant continuing direct cash flows. The telecom systems results of operations were previously included in the Company’s Business Services segment.

5.              Adjusted EBITDA is defined as net income (loss) before interest expense and other, net, income taxes, depreciation and amortization, stock-based compensation expense, impairment of goodwill and intangible assets, restructuring, acquisition and integration-related costs, and loss from discontinued operations, net of tax.  Unlevered Free Cash Flow is defined as net income (loss) before interest expense and other, net, income taxes, depreciation and amortization, stock-based compensation expense, impairment of goodwill and intangible assets, restructuring, acquisition and integration-related costs, and loss from discontinued operations, net of tax, less cash used for purchases of property and equipment. Net Loss Excluding Valuation Allowance is defined as net loss excluding the non-cash charge to record a valuation allowance against deferred tax assets.

Adjusted EBITDA, Unlevered Free Cash Flow and Net Loss Excluding Valuation Allowance are non-GAAP measures and are not determined in accordance with U.S. generally accepted accounting principles. These non-GAAP financial measures are commonly used in the industry and are presented because management believes they provide relevant and useful information to investors. Management uses these non-GAAP financial measures to evaluate the performance of its business and determine bonuses. Management believes that excluding the effects of certain non-cash and non-operating

items enables investors to better understand and analyze the current period’s results and provides a better measure of comparability. There are limitations to using these non-GAAP financial measures. Adjusted EBITDA, Unlevered Free Cash Flow and Net Loss Excluding Valuation Allowance are not indicative of cash provided or used by operating activities and may differ from comparable information provided by other companies.  Adjusted EBITDA, Unlevered Free Cash Flow and Net Loss Excluding Valuation Allowance should not be considered in isolation, as an alternative to, or more meaningful than measures of financial performance determined in accordance with U.S. GAAP.

6.              The Company reports segment information along the same lines that its chief executive officer reviews its operating results in assessing performance and allocating resources. The Company operates two reportable segments, Business Services and Consumer Services. The Company’s Business Services segment provides a broad range of data, voice and IT services to retail and wholesale business customers. The Company’s Consumer Services segment provides nationwide Internet access and related value-added services to residential customers.

The Company presents its Business Services revenue in the following three categories: (1) retail services, which includes data, voice and IT services provided to business customers; (2) wholesale services, which includes the sale of transmission capacity to other telecommunications carriers and businesses; and (3) other services, which primarily consists of web hosting. The Company’s IT services, which are included within its retail services, include data centers, virtualization, security, applications, premises-based solutions, managed solutions and support services. The Company presents its Consumer Services revenue in the following two categories: (1) access services, which includes narrowband and broadband Internet access services; and (2) value-added services, which includes revenues from ancillary services sold as add-on features to EarthLink’s Internet access services, such as security products, premium email only, home networking and email storage; search revenues; and advertising revenues.

EarthLink evaluates performance of its operating segments based on segment income from operations. Segment income from operations includes revenues from external customers, related cost of revenues and operating expenses directly attributable to the segment, which include expenses over which segment managers have direct discretionary control, such as advertising and marketing programs, customer support expenses, site operations expenses, product development expenses, certain technology and facilities expenses, billing operation and provisions for doubtful accounts. Segment income from operations excludes other income and expense items and certain expenses that segment managers do not have discretionary control over. Costs excluded from segment income from operations include various corporate expenses (consisting of certain costs such as corporate management, human resources, finance and legal), depreciation and amortization, stock-based compensation expense, impairment of goodwill and intangible assets and restructuring, acquisition and integration-related costs, as they are not evaluated in the measurement of segment performance.

7.              Debt represents the principal amount of EarthLink’s Senior Notes, EarthLink’s Senior Secured Notes and ITC^DeltaCom’s Senior Secured Notes. Below is a summary of the carrying amount of EarthLink’s debt (in thousands):

8.              Represents full-time equivalents.

9.              Average subscribers for the three month periods is calculated by averaging the ending monthly subscribers or accounts for the four months preceding and including the end of the quarterly period.

10.       ARPU represents the average monthly revenue per user (subscriber). ARPU is computed by dividing average monthly revenue for the period by the average number of subscribers for the period. Average monthly revenue used to calculate ARPU includes recurring service revenue as well as nonrecurring revenues associated with equipment and other one-time charges associated with initiating or discontinuing services.

11.       Churn rate is used to measure the rate at which subscribers discontinue service on a voluntary or involuntary basis.  Churn rate is computed by dividing the average monthly number of subscribers that discontinued service during the period by the average subscribers for the period.
