While management presently believes that the ultimate outcome of such proceedings, individually and in the aggregate, will not materially harm the Company s financial position, cash flows, or overall trends in results of operations, legal proceedings are subject to inherent uncertainties, and unfavorable rulings could occur. An unfavorable ruling could include money damages or, in matters for which injunctive relief or other conduct remedies may be sought, an injunction prohibiting the Company from selling one or more products at all or in particular ways. Were unfavorable final outcomes to occur, there exists the possibility of a material adverse impact on the Company s business, results of operation, financial position and overall trends. The outcomes in these matters are not reasonably estimable.
