We currently rely on a limited number of suppliers for raw materials and key components in the manufacturing of our products, such as tires, landing gear, axles, suspensions, specialty steel coil, stainless steel, plastic, aluminum and lumber. There have been, and may continue to be, shortages of supplies of raw materials or components (including foam insulation, suspension components and wiring), or our suppliers may place us on allocation, which has and would continue to have an adverse impact on our ability to meet demand for our products. Disruptions to the supply chain, shortages and allocations of raw materials and components have resulted and may continue to result in an increased backlog of orders for trailers and certain other products and inefficient operations, and in some cases may produce a build-up of inventory, all of which can negatively affect our working capital position, increase costs that are passed on to customers and delay our ability to fulfill customer orders. The loss of any of our suppliers or their inability to meet our price, quality, quantity and delivery requirements could have a material adverse effect on our business, financial condition, cash flows and results of operations. In addition, price volatility and changes in the availability of commodities we purchase, which have fluctuated significantly in the past, impact the pricing of raw materials, can increase production costs and could have negative impacts on our operating margins.
The ongoing global supply chain disruption continues to interfere with our ability to receive raw materials, components and commodities as scheduled and at expected costs. Such disruptions have been compounded with logistical factors that include reduced freight, railway, trucking and air capacity and delays, shortages of shipping containers and chassis, natural disasters and severe weather conditions, trade conflicts and labor availability constraints, which have resulted in increased transportation costs, shortages of raw materials, components and commodities, inefficient order fulfillment and significant order backlogs. Our supply chain may also continue to be impacted by damaging weather or acts of nature (including acts of nature caused by climate change). Supply chain disruptions, which may also include capacity constraints, effects of economic downturn, cybersecurity threats, geopolitical uncertainties and other related interferences, could have a material adverse effect on our business, financial condition, cash flows and results of operations.
