Certain statements contained in this Current Report on Form 8-K may be deemed to be forward-looking statements under federal securities laws, and we intend that such forward-looking statements be subject to the safe-harbor created thereby. Such forward-looking statements include, but are not limited to, statements regarding our belief that there remains significant opportunity for growth and market share gains with the M&P^® polymer pistol product family; our growth strategy, including taking market share with our M&P^® polymer pistol, leveraging our established high-value product portfolio, and bringing to market innovative new products that meet the needs, wants, and desires of a growing and diverse base of responsible firearm consumers; our expectation to spend more in support of our growth strategy; our outlook for operating expenses in the first quarter of fiscal 2014; our intention to continue to add the capacity and flexibility to service our backlog and to invest in the maintenance and health of our infrastructure and systems, particularly in operations and IT; our outlook for capital expenditures for fiscal 2014; our intention to buy back up to $100 million of our common stock, up to $75 million of which is planned to occur through a fixed-price tender offer and the remaining balance to occur through open market or private transactions; the expected closing date of the tender offer; our plan to only add capacity intelligently, where we believe it is appropriate and with a focus on balancing internal capacity expansion with the outsourcing of selected components; our focus on staying prepared, as best we can, for changes in the marketplace, including by continuing to execute our product innovation strategy, investing in marketing initiatives that communicate with the consumer and raise brand awareness, continuing to add flexible capacity both internally and externally, seeking process improvements and cost reductions, and improving the processes we use to operate our business and distribute products in the marketplace; our outlook for net sales, EPS, and EBITDAS for full year fiscal 2014; our expectation of typical seasonality in our business with our strongest quarters being in the first and fourth quarters; our outlook for net sales, EPS, and expenses for the first quarter of fiscal 2014; our expectation to launch a meaningful new product within the next 12 months; our expectation of the number of manufacturing days in each quarter of fiscal 2014; the plan to have an ERP conversion at the end of first quarter of fiscal 2014; our intention to get the recalled rifles back out into the marketplace for our customers and consumers as quickly as possible; and our expected tax rate for fiscal 2014. We caution that these statements are qualified by important factors that could cause actual results to differ materially from those reflected by such forward-looking statements. Such factors include the demand for our products; the costs and ultimate conclusion of certain legal matters, including the DOJ and SEC matters; the state of the U.S. economy; general economic conditions and consumer spending patterns; the potential for increased regulation of firearms and firearm-related products; speculation surrounding fears of terrorism and crime; our growth opportunities; our anticipated growth; our ability to increase demand for our products in various markets, including consumer, law enforcement, and military channels, domestically and internationally; the position of our hunting products in the consumer discretionary marketplace and distribution channel; our penetration rates in new and existing markets; our strategies; our ability to introduce new products; the success of new products; our ability to expand our markets; the potential for cancellation of orders from our backlog; and other risks detailed from time to time in our reports filed with the SEC, including our Form 10-K Report for the fiscal year ended April 30, 2013.
