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 Global Crossing 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 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.
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 first quarter of 2013 was $15 million. SG&A, Adjusted EBITDA and Adjusted
EBITDA margin for the first quarter of 2013 have been adjusted on a pro forma basis to include the $15 million
to present the results on a consistent basis with the accrual of bonus compensation expense in 2014 as 100
percent cash.

Non-GAAP Reconciliation

14. Issued on April 30, 2014

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.

Schedule To Reconcile To Non-GAAP Financial Metrics
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.)
Gross Margin ($) is defined as total revenue less cost of revenue from the Consolidated
Statements of Operations.
Gross Margin (%) is defined as gross margin ($) divided by total revenue. Management
believes that gross 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.

16. Issued on April 30, 2014

Schedule To Reconcile To Non-GAAP Financial Metrics
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.

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.

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.

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.
