Debt Disclosure [Abstract]
Long-Term Debt	Long-Term Debt Revolving Credit Facility We have a revolving credit facility that we entered into in April 2018 with Wells Fargo Bank, National Association, as administrative agent, and certain other financial institutions party thereto (the “Revolving Credit Facility”), with a maturity date of October 10, 2022. The Revolving Credit facility includes a committed senior secured asset-based revolving loan and letter of credit facility of up to $600 million, and an uncommitted accordion feature that permits us to increase the facility by an aggregate additional principal amount of up to $150 million. Our obligations under the Revolving Credit Facility are secured by a security interest in substantially all of our assets other than real property. Loans under the Revolving Credit Facility bear interest at a rate per annum equal to (i) LIBOR plus a margin ranging from 1.75 percent to 2.25 percent, with the amount of such margin determined based upon the average of our excess availability for the immediately preceding fiscal quarter as calculated by the administrative agent, for loans based on LIBOR, or (ii) the administrative agent’s base rate plus a margin ranging from 0.75 percent to 1.25 percent, with the amount of such margin determined based upon the average of our excess availability for the immediately preceding fiscal quarter as calculated by the administrative agent, for loans based on the base rate. We amended the Revolving Credit Facility on January 31, 2020, to provide that (i) the “Seasonal Period” will run from November 15, 2019, through July 15, 2020, for the calendar year 2019, and from December 15 of each calendar year through April 15 of each immediately succeeding calendar year for the calendar year 2020 and thereafter, and (ii) the measurement period in the definition of “Cash Dominion Event” will be five consecutive business days instead of three consecutive business days. The adjustment to the Seasonal Period better aligns advance rates under the Revolving Credit Facility with the seasonality in our business and provides us with an enhanced borrowing base and greater liquidity through July 15, 2020. As of March 28, 2020, we had outstanding borrowings of $381.6 million, excess availability of $96.8 million, and a weighted average interest rate of 3.2 percent. As of December 28, 2019, our principal balance was $326.5 million, excess availability was $80.0 million, and our weighted average interest rate was 3.9 percent. The Revolving Credit Facility contains certain financial and other covenants, and our right to borrow under the Revolving Credit Facility is conditioned upon, among other things, our compliance with these covenants. We were in compliance with all covenants under the Revolving Credit Facility as of March 28, 2020. Term Loan Facility We have a term loan facility that we entered into in April 2018 with HPS Investments Partners, LLC, as administrative and collateral agent, and certain other financial institutions party thereto (the “Term Loan Facility”), with a maturity date of October 13, 2023. The Term Loan Facility provides for a senior secured first lien loan facility in an initial aggregate principal amount of $180 million and is secured by a security interest in substantially all of our assets. The Term Loan Facility requires monthly interest payments, and also requires quarterly principal payments of $450,000, in arrears, with the remaining balance due on the maturity date. The Term Loan Facility also requires certain mandatory prepayments of outstanding loans, subject to certain exceptions. The Term Loan Facility required maintenance of a total net leverage ratio of 6.25 to 1.00 for the quarter ending March 28, 2020, and requires a ratio of 8.75 to 1.00 for the second and third quarters of 2020, and ratio levels generally reduce over the remaining term of the Term Loan Facility. We were in compliance with all covenants under the Term Loan Facility as of March 28, 2020. Borrowings under the Term Loan Facility may be made as Base Rate Loans or Eurodollar Rate Loans. The Base Rate Loans will bear interest at the rate per annum equal to (i) the greatest of the (a) U.S. prime lending rate published in The Wall Street Journal, (b) the Federal Funds Effective Rate plus 0.50 percent, and (c) the sum of the Adjusted Eurodollar Rate of one month plus 1.00 percent, provided that the Base Rate shall at no time be less than 2.00 percent per annum; plus (ii) the Applicable Margin, as described below. Eurodollar Rate Loans will bear interest at the rate per annum equal to (i) the ICE Benchmark Administration LIBOR Rate, provided that the Adjusted Eurodollar Rate shall at no time be less than 1.00 percent per annum; plus (ii) the Applicable Margin. The Applicable Margin will be 6.00 percent with respect to Base Rate Loans and 7.00 percent with respect to Eurodollar Rate Loans. We amended the Term Loan Facility on December 31, 2019, to extend the period for satisfying the designated principal balance level required to maintain the modified total net leverage ratio covenant levels for the 2019 fourth and subsequent quarters thereunder, which was satisfied on January 31, 2020, through repayments from proceeds from the real estate financing transactions described in Note 8. On February 28, 2020, we further amended the Term Loan Facility to provide that we would not be subject to the facility’s total net leverage ratio covenant from and after the time, and then for so long as, the principal balance level under the facility is less than $45 million. On April 1, 2020, we amended the Term Loan Facility to, among other things, modify the total net leverage ratio covenant levels for the 2020 second and third quarters. All other total net leverage ratio covenant levels for prior and future quarters were unchanged. As of March 28, 2020, we had outstanding borrowings of $77.4 million under the Term Loan Facility and an interest rate of 8.6 percent per annum. As of December 28, 2019, our principal balance was $146.7 million with an interest rate of 8.7 percent per annum. The decrease in the outstanding borrowings was due to net proceeds of the real estate financing transactions described in Note 8 being applied to the Term Loan Facility.
