We are subject to risks associated with our distributors’ product inventories.

We rely on third parties to provide services and technology necessary for the operation of our business. Any failure of one or more of our vendors, suppliers or licensors to provide such services or technology could harm our business.

We are subject to governmental export and import controls that could subject us to liability or impair our ability to compete in international markets, including China. In addition, our ability to sell certain products to certain China customers has been restricted.

Economic volatility and adverse economic conditions have affected and may continue to affect the demand for our products and our customers’ products. Reduced demand for our customers’ products may negatively affect demand for our products and lead to a buildup of inventory at many of our customers, including their affiliates, partners, and contract manufacturers. Reduced demand for our products could result in decreases in our sales and materially harm our results of operations.
