Forward-Looking Statements This document contains forward-looking statements within the scope of the Securities Act of 1933 and the Securities Exchange Act of 1934. The words “expect,” “estimate,” “anticipate,” “predict” and similar expressions, and the negatives thereof, often identify forward-looking statements, which are not limited to historical facts. Our forward-looking statements include, among other things: guidance for the second quarter of 2016 relating to sales; statements, express or implied, concerning future operating results or margins, the ability to generate sales, income or cash flow; and Benchmark’s business and growth strategies and expected growth and performance. Although Benchmark believes these statements are based upon reasonable assumptions, they involve risks and uncertainties relating to our operations, markets and business environment generally. If one or more of these risks or uncertainties materializes, or underlying assumptions prove incorrect, actual outcomes may vary materially from those indicated. All forward-looking statements included in this document are based upon information available to Benchmark as of the date of this document, and the Company assumes no obligation to update them. Readers are advised to consult further disclosures on related subjects, particularly in Item 1A, “Risk Factors” of the Company’s annual report on Form 10-K for the year ended December 31, 2015, in its other filings with the Securities and Exchange Commission and in its press releases. Non-GAAP Financial Information This document includes certain financial measures, such as operating margin, that exclude certain items and therefore are not in accordance with generally accepted accounting principles (“GAAP”). A detailed reconciliation between GAAP results and results excluding special items (“non-GAAP”) is included in the Appendix of this document.
