Cautionary Statement & Pro Forma Adjustment
2
Some statements made in this presentation are forward-looking in nature and are based on management's current expectations or
beliefs. These forward-looking statements are not a guarantee of performance and are subject to a number of uncertainties and other
factors, many of which are outside Level 3's control, which could cause actual events to differ materially from those expressed or
implied by the statements. Important factors that could prevent Level 3 from achieving its stated goals include, but are not limited to, the
company's ability to: successfully integrate the tw telecom acquisition or otherwise realize the anticipated benefits thereof; manage risks
associated with continued uncertainty in the global economy; maintain and increase traffic on its network; develop and maintain
effective business support systems; manage system and network failures or disruptions; avert the breach of its network and computer
system security measures; develop new services that meet customer demands and generate acceptable margins; defend intellectual
property and proprietary rights; manage the future expansion or adaptation of its network to remain competitive; manage continued or
accelerated decreases in market pricing for communications services; obtain capacity for its network from other providers and
interconnect its network with other networks on favorable terms; attract and retain qualified management and other personnel;
successfully integrate the tw telecom and future acquisitions; effectively manage political, legal, regulatory, foreign currency and other
risks it is exposed to due to its substantial international operations; mitigate its exposure to contingent liabilities; and meet all of the
terms and conditions of its debt obligations. Additional information concerning these and other important factors can be found within
Level 3's filings with the Securities and Exchange Commission. Statements in this presentation should be evaluated in light of these
important factors. Level 3 is under no obligation to, and expressly disclaims any such obligation to, update or alter its forward-looking
statements, whether as a result of new information, future events, or otherwise.
Level 3 and tw telecom results on a standalone basis exclude intercompany eliminations, acquisition-related expenses, and acquisition
accounting adjustments associated with the acquisition of tw telecom in 2014.
In 2013, the company accrued 60 percent of its annual employee bonus compensation expense in the form of equity and 40 percent in
cash, compared to 100 percent cash in 2014. The amount of the bonus accrued as equity based compensation in the fourth quarter of
2013 was $18 million. Network Related Expenses, SG&A, Adjusted EBITDA and Adjusted EBITDA margin for the fourth quarter of
2013 have been adjusted on a pro forma basis to include the $18 million to present the results on a consistent basis with the accrual of
bonus compensation expense in 2014 as 100 percent cash.

Level 3 Non-GAAP Reconciliation

21. Issued on February 4, 2015
Schedule To Reconcile To Non-GAAP Financial Metrics
21
Pursuant to Regulation G, the company is hereby providing definitions of non-GAAP financial metrics
and reconciliations to the most directly comparable GAAP measures.
The following describes and reconciles those financial measures as reported under accounting
principles generally accepted in the United States (GAAP) with those financial measures as adjusted by
the items detailed below and presented in the accompanying news release. These calculations are not
prepared in accordance with GAAP and should not be viewed as alternatives to GAAP. In keeping with
its historical financial reporting practices, the company believes that the supplemental presentation of
these calculations provides meaningful non-GAAP financial measures to help investors understand and
compare business trends among different reporting periods on a consistent basis.
In addition, measures referred to in the accompanying news release as being calculated “on a constant
currency basis” or "in constant currency terms" are non-GAAP metrics intended to present the relevant
information assuming a constant exchange rate between the two periods being compared. Such metrics
are calculated by applying the currency exchange rates used in the preparation of the prior period
financial results to the subsequent period results.

22. Issued on February 4, 2015

Consolidated Revenue is defined as total revenue from the Consolidated Statements of Operations.
Core Network Services Revenue includes revenue from colocation and datacenter services, transport and
fiber, IP and data services, and voice services (local and enterprise).
Network Access Costs includes leased capacity, right-of-way costs, access charges, satellite transponder
lease costs and other third party costs directly attributable to providing access to customer locations from
the Level 3 network, but excludes Network Related Expenses, and depreciation and amortization. Network
Access Costs do not include any employee expenses or impairment expenses; these expenses are
allocated to Network Related Expenses or Selling, General and Administrative Expenses.
Network Related Expenses includes certain expenses associated with the delivery of services to
customers and the operation and maintenance of the Level 3 network, such as facility rent, utilities,
maintenance and other costs, each related to the operation of its communications network, as well as
salaries, wages and related benefits (including non-cash stock-based compensation expenses) associated
with personnel who are responsible for the delivery of services, operation and maintenance of its
communications network, and accretion expense on asset retirement obligations, but excludes depreciation
and amortization.

23. Issued on February 4, 2015
Schedule To Reconcile To Non-GAAP Financial Metrics
23
Network Access Margin ($) is defined as total Revenue less Network Access Costs from the
Consolidated Statements of Operations, and excludes Network Related Expenses.
Network Access Margin (%) is defined as Network Access Margin ($) divided by total Revenue.
Management believes that network access margin is a relevant metric to provide to investors, as it
is a metric that management uses to measure the margin available to the company after it pays
third party network services costs; in essence, a measure of the efficiency of the company’s
network.
Adjusted EBITDA is defined as net income (loss) from the Consolidated Statements of Operations
before income taxes, total other income (expense), non-cash impairment charges, depreciation and
amortization and non-cash stock compensation expense.
Adjusted EBITDA Margin is defined as Adjusted EBITDA divided by total revenue.

24. Issued on February 4, 2015
Schedule To Reconcile To Non-GAAP Financial Metrics
24
Management believes that Adjusted EBITDA and Adjusted EBITDA Margin are relevant and useful metrics to provide to
investors, as they are an important part of the company’s internal reporting and are key measures used by Management
to evaluate profitability and operating performance of the company and to make resource allocation decisions.
Management believes such measures are especially important in a capital-intensive industry such as
telecommunications. Management also uses Adjusted EBITDA and Adjusted EBITDA Margin to compare the company’s
performance to that of its competitors and to eliminate certain non-cash and non-operating items in order to consistently
measure from period to period its ability to fund capital expenditures, fund growth, service debt and determine bonuses.
Adjusted EBITDA excludes non-cash impairment charges and non-cash stock compensation expense because of the
non-cash nature of these items. Adjusted EBITDA also excludes interest income, interest expense and income taxes
because these items are associated with the company’s capitalization and tax structures. Adjusted EBITDA also excludes
depreciation and amortization expense because these non-cash expenses primarily reflect the impact of historical capital
investments, as opposed to the cash impacts of capital expenditures made in recent periods, which may be evaluated
through cash flow measures. Adjusted EBITDA excludes the gain (or loss) on extinguishment and modification of debt
and other, net because these items are not related to the primary operations of the company.
There are limitations to using Adjusted EBITDA as a financial measure, including the difficulty associated with comparing
companies that use similar performance measures whose calculations may differ from the company’s calculations.
Additionally, this financial measure does not include certain significant items such as interest income, interest expense,
income taxes, depreciation and amortization, non-cash impairment charges, non-cash stock compensation expense, the
gain (or loss) on extinguishment and modification of debt and net other income (expense). Adjusted EBITDA and
Adjusted EBITDA Margin should not be considered a substitute for other measures of financial performance reported in
accordance with GAAP.

Schedule To Reconcile To Non-GAAP Financial Metrics
Debt is defined as total gross debt including capital leases from the Consolidated Balance Sheet.
Net Debt to Last Twelve Months (LTM) Adjusted EBITDA Ratio is defined as debt, reduced by cash and cash equivalents and
divided by LTM Adjusted EBITDA Pro Forma to include tw telecom results excluding acquisition-related expenses.
Unlevered Cash Flow is defined as net cash provided by (used in) operating activities less capital expenditures, plus cash
interest paid and less interest income all as disclosed in the Consolidated Statements of Cash Flows or the Consolidated
Statements of Operations. Management believes that Unlevered Cash Flow is a relevant metric to provide to investors, as it is an
indicator of the operational strength and performance of the company and, measured over time, provides management and
investors with a sense of the underlying business’ growth pattern and ability to generate cash. Unlevered Cash Flow excludes
cash used for acquisitions and debt service and the impact of exchange rate changes on cash and cash equivalents balances.
There are material limitations to using Unlevered Cash Flow to measure the company’s cash performance as it excludes certain
material items such as payments on and repurchases of long-term debt, interest income, cash interest expense and cash used to
fund acquisitions. Comparisons of Level 3’s Unlevered Cash Flow to that of some of its competitors may be of limited usefulness
since Level 3 does not currently pay a significant amount of income taxes due to net operating losses, and therefore, generates
higher cash flow than a comparable business that does pay income taxes. Additionally, this financial measure is subject to
variability quarter over quarter as a result of the timing of payments related to accounts receivable and accounts payable and
capital expenditures. Unlevered Cash Flow should not be used as a substitute for net change in cash and cash equivalents in the
Consolidated Statements of Cash Flows.

Schedule To Reconcile To Non-GAAP Financial Metrics
26
Free Cash Flow is defined as net cash provided by (used in) operating activities less capital
expenditures as disclosed in the Consolidated Statements of Cash Flows. Management believes
that Free Cash Flow is a relevant metric to provide to investors, as it is an indicator of the
company’s ability to generate cash to service its debt. Free Cash Flow excludes cash used for
acquisitions, principal repayments and the impact of exchange rate changes on cash and cash
equivalents balances.
There are material limitations to using Free Cash Flow to measure the company’s performance
as it excludes certain material items such as principal payments on and repurchases of long-term
debt and cash used to fund acquisitions. Comparisons of Level 3’s Free Cash Flow to that of
some of its competitors may be of limited usefulness since Level 3 does not currently pay a
significant amount of income taxes due to net operating losses, and therefore, generates higher
cash flow than a comparable business that does pay income taxes. Additionally, this financial
measure is subject to variability quarter over quarter as a result of the timing of payments related
to interest expense, accounts receivable and accounts payable and capital expenditures. Free
Cash Flow should not be used as a substitute for net change in cash and cash equivalents on the
Consolidated Statements of Cash Flows.

tw telecom Non-GAAP Reconciliation

33. Issued on February 4, 2015

Pursuant to Regulation G, the Company is hereby providing definitions of tw telecom’s non-GAAP financial metrics and reconciliations to the most directly comparable GAAP
measures.
The following describes and reconciles those financial measures as reported under GAAP with those financial measures as adjusted by the items detailed below and
presented in the accompanying news release. These calculations are not prepared in accordance with GAAP and should not be viewed as alternatives to GAAP. In keeping
with its historical financial reporting practices, the company believes that the supplemental presentation of these calculations provides meaningful non-GAAP financial
measures to help investors understand and compare business trends among different reporting periods on a consistent basis.
Management provides financial measures of tw telecom using U.S. generally accepted accounting principles (“GAAP”) as well as adjustments to GAAP measures to describe
its business trends, including Modified EBITDA. Management believes that its definition of Modified EBITDA is a standard measure of operating performance and liquidity
that is commonly reported and widely used by analysts, investors, and other interested parties in the telecommunications industry because it eliminates many differences in
financial, capitalization, and tax structures, as well as non-cash and non-operating income or charges to earnings. Modified EBITDA is not intended to replace operating
income (loss), net income (loss), cash flow, and other measures of financial performance and liquidity reported in accordance with GAAP. Management uses Modified
EBITDA internally to assess on-going operations and it is the basis for various financial covenants contained in the Company’s debt agreements and for operating
performance and liquidity. Modified EBITDA is reconciled to Net Income (Loss), the most comparable GAAP measure for operating performance within the Consolidated
Operations Highlights.
In addition, management uses unlevered and levered free cash flow, which measure the ability of M-EBITDA to cover capital expenditures. The Company uses these cash
flow definitions to eliminate certain non-cash costs. Levered and unlevered free cash flow are reconciled to Net Cash provided by operating activities.
Modified EBITDA (or “M-EBITDA”) is defined as net income or loss before depreciation, amortization, accretion, impairment charges and other income and losses, interest
expense, debt extinguishment costs, interest income, income tax expense or benefit, cumulative effect of change in accounting principle, and non-cash stock-based
compensation expense. The Company defines Modified EBITDA margin as M-EBITDA divided by total revenue.
Unlevered free cash flow is defined as Modified EBITDA less capital expenditures, which is reconciled to Net Cash provided by (used in) operating activities.
Levered free cash flow is defined as Modified EBITDA less capital expenditures and net interest expense from operations (excluding debt extinguishment costs, non-cash
interest expense and deferred debt costs), which is reconciled to Net Cash provided by (used in) operating activities.
