Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements Assets and liabilities measured at fair value are classified using the following hierarchy, which is based upon the transparency of inputs to the valuation as of the measurement date: • Level 1: Inputs that are based upon quoted prices in active markets for identical assets or liabilities. • Level 2: Inputs, other than quoted prices included within Level 1, which are observable either directly or indirectly. • Level 3: Unobservable inputs where there is little or no market activity for the asset or liability. These inputs reflect management's best estimate of what market participants would use to price the assets or liabilities at the measurement date. The carrying amounts of cash and cash equivalents, accounts receivable, other current assets, accounts payable and accrued liabilities approximate fair value because of the short-term nature of those instruments. In November 2020, the Company entered into an agreement which grants the owner a right during fiscal years 2023 and 2024 to cause the Company to acquire certain assets (the "Put Option") for a price based on a pre-defined formula. The carrying value of this Put Option is reported at fair value each reporting period. The Company measured the fair value of the Put Option using a Monte Carlo simulation. Key assumptions used in the valuation include discount rate, volume volatility, risk-free interest rate, cash flow projections and other details specific to the Put Option. The estimated fair value of the Put Option was zero at both March 28, 2021 and December 27, 2020 and was categorized within Level 3 of the fair value hierarchy. See Note 5 - Debt for fair value of debt.
