The forward-looking statements are not historical facts, and are based upon our current expectations, beliefs, estimates and projections, and various assumptions, many of which, by their nature, are inherently uncertain and beyond our control. Our expectations, beliefs, estimates and projections are expressed in good faith and we believe there is a reasonable basis for them. However, there can be no assurance that management’s expectations, beliefs, estimates and projections will result or be achieved and actual results may vary materially from what is expressed in or indicated by the forward-looking statements. There are a number of risks, uncertainties and other important factors, many of which are beyond our control, that could cause our actual results to differ materially from the forward-looking statements contained in this Annual Report on Form 10-K. Such risks, uncertainties and other important factors that could cause actual results to differ materially include, among others, the risks, uncertainties and factors set forth under “Risk Factors” in Part I, Item 1A of this Annual Report on Form 10-K, including the following: • complex federal and state regulations governing the treatment of animals, which can change, and claims and lawsuits and attempts to generate negative publicity associated with our
