Recent export restrictions have had a significant impact on business. A number of well-established customers and suppliers have become listed on government restricted party lists. In particular, U.S. export enforcement agencies have placed several Chinese companies and many of their international subsidiaries on such lists, prohibiting the export to them of most commercial and dual-use items subject to the Export Administration Regulations. Furthermore, the United States has imposed certain sectoral sanctions to limit Chinese development and manufacturing of semiconductor and supercomputer technology and have imposed comprehensive restrictions of both U.S.-origin items as well as non-U.S. items manufactured from U.S.-origin equipment. In response, China has unveiled restrictions on exports from China of certain materials and components, including gallium and germanium which are used in semiconductor manufacturing and which has impacted the production and pricing of some of our digital imaging products. Many key suppliers to our businesses, whether direct or indirect, are based in China. These and other tariffs, trade restrictions and retaliatory measures could result in revenue reduction, price increases on material used in our products or significant production delays, which could adversely affect our business, financial condition, operational results and cash flows.
Sanctions on Russia imposed by multiple countries and related Teledyne policies have led to a comprehensive ban on commercial activity with that market.
