(1) Long-lived assets include property, plant and equipment and are attributed to the geographic location in which they are located. Customer Concentration and Credit Risk The Company sells its products to computer manufacturers, resellers and retailers throughout the world. For each of 2020, 2019 and 2018, no customer accounted for 10% or more of the Company’s net revenue. For 2020, 2019 and 2018, the Company’s top 10 customers accounted for 42%, 45%, and 42%, respectively, of the Company’s net revenue. The Company performs ongoing credit evaluations of its customers’ financial condition and generally requires no collateral. The Company maintains allowances for potential credit losses, and such losses have historically been within management’s expectations. At any given point in time, the total amount outstanding from any one of a number of its customers may be individually significant to the Company’s financial results. As of July 3, 2020, one customer, Kingston Technology Company, accounted for 10% of the Company’s net accounts receivable. As of June 28, 2019, two customers, Dell Technologies Inc. and Huawei Investment & Holding Co., accounted for 14% and 10%, respectively, of the Company’s net accounts receivable. As of July 3, 2020 and June 28, 2019, the Company had net accounts receivable of $2.4 billion and $1.2 billion, respectively, and reserves for potential credit losses were not material as of each period end. The Company also has cash equivalent and investment policies that limit the amount of credit exposure to any one financial institution or investment instrument and requires that investments be made only with financial institutions or in investment instruments evaluated as highly credit-worthy. Supplier Concentration All of the Company’s flash memory system products require silicon wafers for the memory and controller components. The Company’s flash memory wafers are currently supplied almost entirely from Flash Ventures and the controller wafers are all manufactured by third-party sources. The failure of any of these sources to deliver silicon wafers could have a material adverse effect on the Company’s business, financial condition and results of operations. In addition, some key components are purchased from single source vendors for which alternative sources are currently not available. Shortages could occur in these essential materials due to an interruption of supply or increased demand in the industry. If the Company was unable to procure certain of such materials, the Company’s sales could decline, which could have a material adverse effect upon its results of operations. The Company also relies on third-party subcontractors to assemble and test a portion of its products. The Company does not have long-term contracts with some of these subcontractors and cannot directly control product delivery schedules or manufacturing processes. This could lead to product shortages or quality assurance problems that could increase the manufacturing costs of the Company’s products and have material adverse effects on the Company’s operating results.
