Such forward-looking statements reflect, among other things, our current expectations and anticipated results of operations, all of which are subject to known and unknown risks, uncertainties and other factors that may cause our actual results, performance or achievements, market trends, or industry results to differ materially from those expressed or implied by such forward-looking statements.

Shareholders will be able to obtain a free copy of the proxy statement (when available), as well as other filings made by INC Research regarding INC Research, inVentiv Health, and the proposed transaction, without charge, at the Securities and Exchange Commission’s website (http://www.sec.gov) or at INC Research’s website (investor.incresearch.com).

Important Information (Cont’d)
Non-GAAP Financial Measures
In addition to the financial measures prepared in accordance with GAAP, this presentation contains certain non-GAAP financial measures, including Adjusted Income from Operations, Adjusted Operating Margin, Adjusted Net Income (including Adjusted Diluted Earnings per Share), EBITDA and Adjusted EBITDA. Both INC Research’s and inVentiv Health’s financial statements and the associated non-GAAP measures have been prepared in accordance with their historical accounting and reporting policies. The combined company has not yet determined the conforming policy or adjustments that it will make upon consummation of this merger.
A “non-GAAP financial measure” is generally defined as a numerical measure of a company’s financial performance that excludes or includes amounts so as to be different than the most directly comparable measure calculated and presented in accordance with GAAP in the statements of operations, balance sheets or statements of cash flows of the Company.
The Company defines Adjusted Income from Operations as income from operations excluding expenses and transactions that the Company believes are not representative of its core operations, namely, acquisition-related amortization; restructuring, CEO transition, and other costs; transaction expenses; share-based compensation expense; and contingent consideration related to acquisitions and other expense. The Company defines Adjusted Operating Margin as adjusted income from operations as a percentage of net service revenue.
The Company defines Adjusted Net Income (including Adjusted Diluted Earnings per Share) as net income (including diluted earnings per share) excluding the items excluded from adjusted income from operations mentioned previously and other expense. After giving effect to these items and other unusual tax impacts during the period, the Company has also included an adjustment to its income tax rate to reflect the expected long-term income tax rate.
EBITDA represents earnings before interest, taxes, depreciation and amortization. The Company defines Adjusted EBITDA as EBITDA, further adjusted to exclude certain expenses and transactions that the Company believes are not representative of its core operations, namely, restructuring, CEO transition, and other costs; transaction expenses; share-based compensation expense; contingent consideration related to acquisitions and other expense; and other expense. The Company presents EBITDA and Adjusted EBITDA because it believes they are useful metrics for investors as they are commonly used by investors, analysts and debt holders to measure the Company’s ability to fund capital expenditures and meet working capital requirements.
Each of the non-GAAP measures noted above are used by management and the Board to evaluate the Company’s core operating results as they exclude certain items whose fluctuations from period-to-period do not necessarily correspond to changes in the core operations of the business. Adjusted Income from Operations, Adjusted Operating Margin and Adjusted Net Income (including Adjusted Diluted Earnings per Share) are used by management and the Board to assess the Company’s business.
Non-GAAP measures have limitations in that they do not reflect all of the amounts associated with the Company’s results of operations as determined in accordance with GAAP. Also, other companies might calculate these measures differently. Investors are encouraged to review the reconciliations of the non-GAAP financial measures to their most directly comparable GAAP measures included on slides 18-20 in the appendix of this presentation.
Preliminary InVentiv Health Financial Results
