Concentrations of Credit Risk

12 Months Ended

Mar. 28, 2020

The Company’s principal financial instrument subject to potential concentration of credit risk is accounts receivable, which is unsecured. The Company provides an allowance for doubtful accounts equal to estimated losses expected to be incurred in the collection of accounts receivable. The Company has adopted credit policies and standards intended to accommodate industry growth and inherent risk and it believes that credit risks are moderated by the financial stability of its major customers, conservative payment terms and the Company’s strict credit policies.

Revenue from significant customers, those representing 10% or more of revenue for the respective periods, are summarized as follows:



	Fiscal Year
	2020	2019	2018
Apple Inc. ("Apple") (1)	33%	32%	36%
Huawei Technologies Co., Ltd. and affiliates ("Huawei")	10%	15%	8%

(1) The Company provided its products to Apple through sales to multiple contract manufacturers.

These customers primarily purchase RF solutions for a variety of mobile devices.

Accounts receivable related to these customers (which includes multiple contract manufacturers) accounted for 35%, 49% and 26% of the Company's total net accounts receivable balance as of March 28, 2020, March 30, 2019 and March 31, 2018, respectively.

On May 16, 2019, the Company suspended shipments of products to Huawei after the Bureau of Industry and Security (BIS) of the U.S. Department of Commerce added Huawei Technologies Co., Ltd. and over 100 of its affiliates to the BIS's Entity List. Subsequently, the Company restarted shipments from outside the U.S. of certain products that are not subject to the Export Administration Regulations (EAR) to Huawei in compliance with the BIS order. The Company has also applied for a license to ship other products that are subject to the EAR, as required by the rules governing the Entity List. Sales to Huawei will continue to be impacted by trade restrictions.
