A substantial portion of our revenues are from a limited number of customers. Our revenues are derived mainly from railcar loading and unloading services for bulk liquid products, switching, other terminalling services, and railcar fleet services. The industry concentration of these customers may impact our overall exposure to credit risk, either positively or negatively, since our customers may be similarly affected by changes in commodity prices, regulation, and other economic factors. We seek high-quality customers with investment grade credit ratings and perform ongoing credit evaluations of our customers.
