We obtain materials and manufactured components from third-party suppliers. Principal materials and components used in our various manufacturing processes include steel, castings, engines, tires, hydraulics, cylinders, drive trains, cab chassis, electric controls and motors, semiconductors, and a variety of other commodities and fabricated or manufactured items. The cost and availability of these materials, components and final assemblies have varied significantly in past years. While we have seen improvements in the supply chain, additional fluctuations and disruptions are possible due to demand changes, inflation, geopolitical and economic uncertainty, regulatory and policy instability, the imposition of duties and tariffs and trade agreements/barriers, freight availability and costs, wage increases and labor shortages. The Company has mitigated these risks with price increases on our products, recouped tariffs through duty drawback and exclusions, and working with suppliers to ensure optimum pricing and inventory levels. However, if customers become unwilling to accept any future price increases in the Company's products and the Company is unable to recover a substantial portion of increased costs from our suppliers, or through duty draw-back/exclusions, or otherwise offset the increased costs, then increased fluctuations in costs of materials or inflation generally and supply chain challenges could have a material adverse effect on the Company's results of operation, profitability, free cash flows, and financial condition.
In the absence of labor strikes or other unusual circumstances, substantially all materials and components are normally available from multiple suppliers. However, certain of our businesses receive materials and components from a single source supplier, although alternative suppliers of such materials may be generally available. Delays in our suppliers' abilities, especially any sole suppliers for a particular business, to provide us with necessary materials and components may delay production at a number of our manufacturing locations, or may require us to seek alternative supply sources. Delays in obtaining supplies may result from a number of factors affecting our suppliers, including capacity constraints, regulatory changes, global logistics network challenges and cost increases, labor shortages and disputes, wage increases, inflation, suppliers' impaired financial condition, suppliers' allocations to other purchasers, weather emergencies, pandemics or acts of war or terrorism. We actively monitor and mitigate our supply chain risk, but there can be no assurance that our mitigation plans will be effective. Any delay or disruptions in receiving supplies could result in manufacturing inefficiencies caused by us having to wait for parts to arrive on production lines, could impair our ability to deliver products to our customers and delay sales, and, accordingly, could have a material adverse effect on our business, results of operations, financial condition and/or cash flows.
In addition, we purchase material and services from our suppliers on terms extended based on our overall credit rating. Deterioration in our credit rating may impact suppliers' willingness to extend terms and in turn accelerate cash requirements of our business.
