2. Forward Looking Statements, Reconciliation and Use of Non-GAAP Measures
to U.S. GAAP
This presentation may contain “forward-looking statements,” which include information concerning the company’s
plans, objectives, goals, strategies, future revenues or performance, capital expenditures, financing needs and other
information that is not historical information. When used in this release, the words “outlook,” “forecast,”
“estimates,” “expects,” “anticipates,” “projects,” “plans,” “intends,” “believes,” and variations of such words or
similar expressions are intended to identify forward-looking statements. All forward-looking statements are based
upon current expectations and beliefs and various assumptions. There can be no assurance that the company will
realize these expectations or that these beliefs will prove correct. There are a number of risks and uncertainties that
could cause actual results to differ materially from the forward-looking statements contained in this release.
Numerous factors, many of which are beyond the company’s control, could cause actual results to differ materially
from those expressed as forward-looking statements. Certain of these risk factors are discussed in the company’s
filings with the Securities and Exchange Commission. Any forward-looking statement speaks only as of the date on
which it is made, and the company undertakes no obligation to update any forward-looking statements to reflect
events or circumstances after the date on which it is made or to reflect the occurrence of anticipated or unanticipated
events or circumstances.
This presentation reflects three performance measures, operating EBITDA, adjusted earnings per share and net debt
as non-U.S. GAAP measures. The most directly comparable financial measure presented in accordance with U.S.
GAAP in our consolidated financial statements for operating EBITDA is operating profit; for adjusted earnings per
share is earnings per common share-diluted; and for net debt is total debt.
Operating EBITDA, a measure used by management to measure performance, is defined as operating profit
from continuing operations, plus equity in net earnings from affiliates, other income and depreciation and
amortization, and further adjusted for other charges and adjustments. Our management believes
operating EBITDA is useful to investors because it is one of the primary measures our management uses for
its planning and budgeting processes and to monitor and evaluate financial and operating results.
Operating EBITDA is not a recognized term under U.S. GAAP and does not purport to be an alternative to
operating profit as a measure of operating performance or to cash flows from operating activities as a
measure of liquidity. Because not all companies use identical calculations, this presentation of operating
EBITDA may not be comparable to other similarly titled measures of other companies. Additionally,
operating EBITDA is not intended to be a measure of free cash flow for management’s discretionary use, as
it does not consider certain cash requirements such as interest payments, tax payments and debt service
requirements nor does it represent the amount used in our debt covenants.
Adjusted earnings per share is a measure used by management to measure performance. It is defined as net
earnings (loss) available to common shareholders plus preferred dividends, adjusted for other charges and
adjustments, and divided by the number of basic common shares, diluted preferred shares, and options
valued using the treasury method. We provide guidance on an adjusted earnings per share basis and are
unable to reconcile forecasted adjusted earnings per share to a GAAP financial measure because a forecast
of Other Items is not practical. We believe that the presentation of this non-U.S. GAAP measure provides
useful information to management and investors regarding various financial and business trends relating
to our financial condition and results of operations, and that when U.S. GAAP information is viewed in
conjunction with non-U.S. GAAP information, investors are provided with a more meaningful
understanding of our ongoing operating performance. This non-U.S. GAAP information is not intended to
be considered in isolation or as a substitute for U.S. GAAP financial information.
Net debt is defined as total debt less cash and cash equivalents. We believe that the presentation of this
non-U.S. GAAP measure provides useful information to management and investors regarding changes to
the company’s capital structure. Our management and credit analysts use net debt to evaluate the
company's capital structure and assess credit quality. This non-U.S. GAAP information is not intended to
be considered in isolation or as a substitute for U.S. GAAP financial information.
