Suppliers The Company has a large number of components and sub-assemblies produced by outside suppliers, some of which are sourced from a single supplier, which can magnify the risk of shortages and decrease the Company’s ability to negotiate with suppliers on the basis of price. In particular, the Company depends on one supplier of compression drivers for its LRAD products. If supplier shortages occur, or quality problems arise, then production schedules could be significantly delayed or costs significantly increased, which could in turn have a material adverse effect on the Company’s financial condition, results of operation and cash flows.
