Commitments and Contingencies Disclosure [Abstract] |
Commitments and Contingencies | Commitments and Contingencies Facilities and Equipment Under Operating and Capital Lease Agreements We currently own our corporate headquarters and select surrounding properties. We lease certain of our other facilities and certain equipment under operating lease agreements, some of which have renewal options. Certain of these arrangements provide for lease payment increases based upon future fair market rates. As of March 30, 2019, our principal facilities are located in Austin, Texas and Edinburgh, Scotland, United Kingdom. Total rent expense under operating leases was approximately $12.7 million, $11.5 million, and $8.2 million, for fiscal years 2019, 2018, and 2017, respectively. Rental income was $0.2 million, $0.3 million, and $0.4 million, for fiscal years 2019, 2018, and 2017, respectively. As of March 30, 2019, the aggregate minimum future rental commitments under all operating leases, net of lease income for the following fiscal years are (in thousands):

Wafer, Assembly, Test and Other Purchase Commitments We rely primarily on third-party foundries for our wafer manufacturing needs. Generally, our foundry agreements do not have volume purchase commitments and primarily provide for purchase commitments based on purchase orders. Cancellation fees or other charges may apply and are generally dependent upon whether wafers have been started or the stage of the manufacturing process at which the notice of cancellation is given. As of March 30, 2019, we had foundry commitments of $62.6 million. In addition to our wafer supply arrangements, we contract with third-party assembly vendors to package the wafer die into finished products. Assembly vendors provide fixed-cost-per-unit pricing, as is common in the semiconductor industry. We had non-cancelable assembly purchase orders with numerous vendors totaling $1.4 million at March 30, 2019. Test vendors provide fixed-cost-per-unit pricing, as is common in the semiconductor industry. Our total non-cancelable commitment for outside test services as of March 30, 2019 was $10.1 million. Other purchase commitments primarily relate to multi-year tool commitments, and were $45.7 million at March 30, 2019.
