Equity and Cost Method Investments [Abstract] |
Cost and Equity Method Investments Disclosure [Text Block] | Note 2. Investments in Affiliates Investments in affiliates over which we have significant influence are accounted for under the equity method of accounting. Investments in affiliates over which we do not have the ability to exert significant influence over the affiliate's operating and financing activities are accounted for under the cost method of accounting. We have evaluated our relationships with our affiliates and have determined that these entities are not variable interest entities. The aggregate amount of investments accounted for under the equity method was $4,236 and $3,647 at October 27, 2018 and April 28, 2018, respectively. The equity method requires us to report our share of losses up to our equity investment amount. Cash paid for investments in affiliates is included in the "Purchases of equity investment" line item in our condensed consolidated statements of cash flows. Our proportional share of the respective affiliates' earnings or losses is included in the "Other (expense) income, net" line item in our condensed consolidated statements of operations. For the six months ended October 27, 2018 and October 28, 2017, our share of the losses of our affiliates was $265 and $191, respectively. The aggregate amount of investments accounted for under the cost method was $42 at October 27, 2018 and April 28, 2018, respectively. There have not been any identified events or changes in circumstances that may have a significant adverse effect on their fair value, and it is not practical to estimate their fair value.
