Q&A

Back Up & Reconciliation Tables

Note On Reconciliation Tables These tables include financial measures adjusted for the impact of certain items; these financial measures are therefore not calculated in accordance with U.S. generally accepted accounting principles (“GAAP”). These Non-GAAP financial measures consider exclusion of: share-based compensation expense; one-time charges relating to restructuring initiatives, non-cash asset impairments, certain other non-operating gains and losses, and acquisition-related items such as one-time transaction costs, non-cash amortization of acquired intangible assets, and the stepped-up cost of sales associated with the purchase accounting of acquired inventory. These non-GAAP financial measures may be different from non-GAAP financial measures used by other companies. Non-GAAP financial measures should not be considered as a substitute for, or superior to, measures of financial performance prepared in accordance with GAAP. By excluding these items, non-GAAP financial measures are intended to facilitate meaningful comparisons to historical operating results, competitors' operating results, and estimates made by securities analysts. Management is evaluated on key performance metrics including adjusted EBITDA, which is used to determine management incentive compensation as well as to forecast future periods. These non-GAAP financial measures may be useful to investors in allowing for greater transparency of supplemental information used by management in its financial and operational decision-making. In addition, similar non-GAAP financial measures have historically been reported to investors; the inclusion of comparable numbers provides consistency in financial reporting. Investors are encouraged to review the reconciliation of the non-GAAP financial measures used in the Company’s news release to their most directly comparable GAAP financial measures.
