Cautionary Statement Regarding Forward-Looking Statements

This Current Report on Form 8-K contains “forward-looking statements,” within the meaning of federal securities laws, which include, without limitation, statements relating to the Company’s ability to make potential future acquisitions. 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.

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. These risk factors include risks associated with the Company’s capital structure and increased debt level; the ability to successfully integrate Sealy into the Company’s operations and realize cost and revenue synergies and other benefits from the transaction; whether the Company will realize the anticipated benefits from its recent asset dispositions and the acquisition of brand rights in certain international markets; general economic, financial and industry conditions, particularly in the retail sector, as well as consumer confidence and the availability of consumer financing; changes in interest rates; uncertainties arising from global events; the effects of changes in foreign exchange rates on the Company’s reported earnings; consumer acceptance of the Company’s products; industry competition; the efficiency and effectiveness of the Company’s advertising campaigns and other marketing programs; the Company’s ability to increase sales productivity within existing retail accounts and to further penetrate the Company’s retail channel, including the timing of opening or expanding within large retail accounts and the timing and success of product launches; the Company’s ability to expand brand awareness, distribution and new products; the Company’s ability to continuously improve and expand its product line, maintain efficient, timely and cost-effective production and delivery of its products, and manage its growth; the effects of strategic investments on the Company’s operations; changes in foreign tax rates and changes in tax laws generally, including the ability to utilize tax loss carry forwards; the outcome of various pending tax audits or other tax proceedings; changing commodity costs; and the effect of future legislative or regulatory changes.

There are a number of risks and uncertainties that could cause the Company’s actual results to differ materially from the forward-looking statements contained in this Report. There are important factors, many of which are beyond the Company’s control, that could cause its actual results to differ materially from those expressed as forward-looking statements in this Report, including the risk factors discussed under the heading “Risk Factors” under ITEM 1A of Part 1 of our Annual Report on Form 10-K for the year ended December 31, 2013. There may be other factors that may cause the Company’s actual results to differ materially from the forward-looking statements.
