Our Aerospace & Electronics segment sales are primarily affected by conditions in the commercial aerospace industry, which is cyclical in nature, and by changes in defense spending by the U.S. government.
Commercial aircraft are procured primarily by airlines, and airline capital spending can be affected by a number of factors including credit availability and related cost, current and expected fuel prices, and current and forecast air traffic demand levels. Air traffic levels are affected by a different array of factors including general economic conditions and global corporate travel spending, although other non-economic events can also adversely impact airline traffic, including terrorism or pandemic health concerns, such as the COVID-19 pandemic. Our commercial business is also affected by the market for business jets where demand is typically tied to corporate profitability levels, and the freight markets which are most heavily influenced by general economic conditions. Demand for our commercial aftermarket business is closely tied to total aircraft flight hours. Any decrease in demand for new aircraft or equipment, or use of existing aircraft and equipment, would result in decreased sales of our products and services. In addition, our commercial business could also be impacted to the extent that our major aircraft manufacturing customers encounter problems which impact their production rates and, correspondingly, reduce purchases of our products, or if pricing pressure from aircraft customers caused the manufacturers to press their suppliers to lower prices and/or extend payment terms.
The defense portion of the segment's business is dependent primarily on U.S. government spending, and to a lesser extent, foreign government spending, on the specific military platforms and programs where our business participates. Any reduction in appropriations for these platforms or programs could impact the performance of our business. Our sales to defense customers are also affected by the level of activity in military flight operations.
We rely on certain subcontractors and suppliers to provide and produce raw materials, integrated components and sub-assemblies. The Aerospace and Defense industry is experiencing continued disruptions due to the lingering impacts of COVID-19 and related global supply chain constraints and labor instability. If one or more of our suppliers or subcontractors continue to experience delivery delays or other performance problems, we may be unable to meet commitments to our customers and our financial position, results of operations and cash flows may continue to be adversely impacted. In some instances, we depend upon a single source of supply. Any service disruption from one of these suppliers, either due to circumstances beyond the supplier's control, such as geopolitical developments, could have a material adverse effect on our ability to meet commitments to our customers or increase our operating costs.
We are required to comply with various export control laws, which may affect our transactions with certain customers. In certain circumstances, export control and economic sanctions regulations may prohibit the export of certain products, services and technologies, and in other circumstances we may be required to obtain an export license before exporting the controlled item. We are also subject to investigation and audit for compliance with the requirements governing government contracts, including requirements related to procurement integrity, manufacturing practices and quality procedures, export control, employment practices, the accuracy of records and the recording of costs and information security requirements. A failure to comply with these requirements could result in suspension of these contracts, and suspension or debarment from government contracting or subcontracting. Failure to comply with any of these regulations could result in civil and criminal liability, monetary and non-monetary penalties, fines, disruptions to our business, limitations on our ability to export products and services, and damage to our reputation.
Due to the lengthy research and development cycle involved in bringing commercial and military products to market, we cannot accurately predict the demand levels that will exist once a given new product is ready for market. In addition, if we are unable to develop and introduce new products in a cost-effective manner or otherwise effectively manage the introduction of new products and/or programs, our results of operations and financial condition could be adversely impacted. Demand for our products could also be adversely impacted by industry consolidation that could result in greater acceptance of competitors' products.
