PPG is currently under contract to supply transparencies, coatings and sealants for use on existing and new commercial, general aviation and military aircraft manufactured by many of the largest global and regional aerospace manufacturers. Our aerospace business is currently experiencing a backlog resulting in product shortages to certain of our customers. In addition, many of our contracts contemplate production increases over the next several years. If we fail to meet production targets and commitments, or encounter difficulty or unexpected costs in meeting such levels, it could have a material effect on our reputation, business, operating results, or financial condition. Similarly, to the extent demand for our products increases rapidly and significantly in future periods, we may not be able to ramp up production quickly enough to meet the demand, which could result in production delays at our customers, lost opportunities for growth and adversely affect our business, financial condition, results of operations or competitive position. Additionally, delivery delays by us due to production interruptions or delays may subject us to liability from customer claims that such delay resulted in losses to the customer.
