Increased reliance on sales of enterprise licenses may result in greater fluctuations in, or otherwise adversely affect, our financial results. Sales of enterprise licenses through our Enterprise Security segment represent a major portion of our business. Enterprise licensing arrangements involve a longer sales cycle than sales through other distribution channels, require greater investment of resources in establishing the enterprise relationship, may involve greater pricing pressure and sometimes result in lower operating margins. In addition, the timing of the execution of volume licenses, or their non-renewal by large customers, could cause our results of operations to vary significantly from quarter to quarter and could have a material adverse impact on our results of operations. In addition, longer license periods impede our ability to increase prices due to increased costs and may adversely impact our operating margins.
