We rely upon information technology systems and network products and the secure operation of these systems and products. Despite security measures, these systems and products may be vulnerable to physical damage, hackers, computer viruses, or breaches due to errors or malfeasance by employees, vendors, or customers. We have experienced such events in the past and, although past events were immaterial, future events may occur and may be material. Additionally, consumers are increasingly shopping online and through mobile commerce applications. As a result, we are vulnerable to additional risks and uncertainties associated with e-commerce sales, including rapid changes in technology, website downtime and other technical failures, security breaches, cyber-attacks, consumer privacy concerns, changes in state tax regimes and government regulation of internet activities. Our failure to successfully respond to these risks and uncertainties could reduce our e-commerce sales and increase our costs, which could negatively impact our results of operations. In addition, there is no guarantee that we will be able to expand our e-commerce business. Our competitors may have e-commerce businesses that are substantially larger and more developed than ours, which could place us at a competitive disadvantage.
