Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments and Hedging Activities Disclosure [Text Block]	Derivative Instruments In fiscal 2017, we entered into an interest rate swap agreement to manage the risk associated with a portion of our variable-rate debt. We do not utilize derivative instruments for speculative purposes. The interest rate swap involves the exchange of fixed-rate and variable-rate payments without the exchange of the underlying notional amount on which the interest payments are calculated. The swap agreement began September 1, 2017, and will terminate concurrently with the expiration of our credit facility on December 23, 2020. The notional amount of the swap agreement is $40 million from September 1, 2017 through August 31, 2018, $30 million from September 1, 2018 through August 31, 2019 and $20 million from September 1, 2019 through December 23, 2020. We have designated this swap as a cash flow hedge and have determined that it qualifies for hedge accounting treatment. For so long as the hedge is effective, changes in fair value of the cash flow hedge are recorded in other comprehensive loss (net of tax) until income or loss from the cash flows of the hedged item is realized. For each of the years ended April 1, 2018 and April 2, 2017, we recorded $0.3 million in other comprehensive income related to unrealized gains (net of tax) on the cash flow hedge. Included in other long-term assets on our condensed consolidated balance sheet was $0.8 million as of April 1, 2018 and $0.5 million as of April 2, 2017. No amounts were reflected in other comprehensive income related to cash flow hedges for the fiscal year ended April 3, 2016 or on the condensed consolidated balance sheet as of April 3, 2016, as we did not hold any derivative instruments at that time. By their nature, derivative instruments are subject to market risk. Derivative instruments are also subject to credit risk associated with counterparties to the derivative contracts. Credit risk associated with derivatives is measured based on the replacement cost should the counterparty with a contract in a gain position to us fail to perform under the terms of the contract. We do not anticipate nonperformance by the counterparty.
