The United States government has indicated and demonstrated its intent to alter its approach to international trade policy through the renegotiation, and termination, of certain existing bilateral and multi-lateral trade agreements and treaties with, and the imposition of tariffs on a wide range of products and other goods from, China and other countries. Given our primary contract manufacturer and a significant product supplier is located in China, and we have limited manufacturing elsewhere, policy changes in the United States or other countries, such as the tariffs already proposed, implemented and threatened, present particular risks for us. Tariffs already announced and implemented, and future tariffs may have an adverse effect on certain of our products. We cannot predict future trade policy, the terms of any renegotiated trade agreements or treaties, or tariffs and their impact on our business. A trade war could have a significant adverse effect on world trade and the world economy. To the extent that trade tariffs and other restrictions imposed by the United States or other countries increase the price of, or limit the amount of, our products or components or materials used in our products imported into the United States or other countries, or create adverse tax consequences, the cost or gross margin of our products may be adversely affected and the demand from our customers for products and services may be diminished. If we deem it necessary to alter all or a portion of our activities or operations in response to such policies, agreements or tariffs, our capital and operating costs may increase. Our ongoing efforts to address these risks may not be effective and may have long-term adverse effects on our operations and operating results that we may not be able to reverse. Such efforts may also take time to implement or to have effect, and may result in adverse quarterly financial results or fluctuations in our quarterly financial results. As a result, changes in international trade policy, changes in trade agreements and tariffs could adversely affect our business, results of operations and financial condition.
