The Company purchases large quantities of raw materials and components such as steel, aluminum, aluminum castings, fabrications, LEDs, power supplies, powder paint, steel tubing, wire harnesses, acrylic, silicon and glass lenses, inks, various graphics substrates such as Aluminum Composite Material (ACM), Expanded PVC sheet (EPVC), vinyl film, styrene, foamboards, wood and wood laminates, condensing units, and digital screens. The Company's operating results could be affected by the availability and price fluctuations of these materials. The Company's strategic sourcing plans include mitigating supply chain risk by utilizing multiple suppliers for a commodity to avoid significant dependence on any single supplier. Although an interruption of these supplies and components could disrupt our operations, we believe generally that alternative sources of supply exist and could be readily arranged. With regard to price fluctuations of our raw material and component purchases, the price risk for materials the Company purchases is related to price increases in commodity items that affect all users of the materials, including the Company's competitors. Significant tariffs or increases in the price of these raw materials and components could further increase the Company's operating costs and materially adversely affect margins. The Company does, however, seek and qualify new suppliers, negotiate with existing suppliers, and arrange stocking agreements to mitigate risk of supply and price increases. The Company can also be impacted by shortages and the availability of transportation of our products to our customers, in addition to rising fuel prices. The Company's Lighting Segment has implemented price increases with customers to offset raw material price increases along, rising transportation costs, and to mitigate the impact of trade tariffs. The Company's Display Solutions Segment generally establishes new sales prices, reflective of the then current raw material prices and transportation costs, for each program as it begins with further price increases throughout the life of the program when warranted. Although the Company attempts to pass along increased costs in the form of price increases to its customers, the Company may be unsuccessful in doing so for competitive reasons. Even when price increases are successful, the timing of such price increases may lag significantly behind the incurrence of higher costs.
