This excerpt taken from the SMG 10-K filed Dec 14, 2006.
Perceptions that the products we produce and market are not safe could adversely affect us and contribute to the risk we will be subjected to legal action. We manufacture and market a number of complex chemical products, such as fertilizers, growing media, herbicides and pesticides, bearing our brand names. On occasion, allegations are made that some of our products have failed to perform up to expectations or have caused damage or injury to individuals or property. Based on reports of contamination at a third party suppliers vermiculite mine, the public may perceive that some of our products manufactured in the past using vermiculite are or may also be contaminated. Public perception that our products are not safe, whether justified or not, could impair our reputation, involve us in litigation, damage our brand names and have a material adverse affect on our business.
