2© 2015 Knoll Inc. Forward-Looking Statements The following information includes forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. These statements discuss goals, intentions and expectations as to future trends, plans, events, results of operations or financial condition, or state other information relating to us, based on our current beliefs as well as assumptions made by us and information currently available to us. Forward-looking statements generally will be accompanied by words such as "anticipate," "believe," "could," "estimate," "expect," "forecast," "intend," "may," "possible," "potential," "predict," "project," or other similar words, phrases or expressions. This includes, without limitation, our statements and expectations regarding any current or future recovery in our industry and publicly announced plans for increased capital and investment spending to achieve our long-term revenue and profitability growth goals, and our expectations with respect to leverage. Although we believe these forward-looking statements are reasonable, they are based upon a number of assumptions concerning future conditions, any or all of which may ultimately prove to be inaccurate. Important factors that could cause actual results to differ materially from the forward-looking statements include, without limitation: the risks identified in Knoll’s annual report on Form 10-K, and other filings with the Securities and Exchange Commission; changes in the financial stability of our clients or the overall economic environment, resulting in decreased corporate spending and service sector employment; changes in relationships with clients; price competition; the mix of products sold and of clients purchasing our products; the success of Knoll’s new products; demand for high quality, well designed furniture solutions; changes in business strategies and decisions; changes in the competitive marketplace; changes in the trends in the market for furniture or coverings; our ability to recruit and retain an experienced management team; the pricing and availability of raw materials and components; transportation costs; restrictions on government spending resulting in fewer sales to the U.S. government, one of our largest customers; our debt restrictions on spending; our ability to protect our patents, copyrights and trademarks; our reliance on furniture dealers to produce sales; lawsuits arising from patents, copyrights and trademark infringements; violations of environmental laws and regulations; potential labor disruptions; adequacy of our insurance policies; the availability of future capital and the cost of borrowing; the overall strength and stability of our dealers, suppliers, and customers; access to necessary capital; our ability to successfully integrate acquired businesses; the success of our design and implementation of a new enterprise resource planning system; and currency rate fluctuations. The factors identified above are believed to be important factors (but not necessarily all of the important factors) that could cause actual results to differ materially from those expressed in any forward-looking statement. Unpredictable or unknown factors could also have material adverse effects on us.
