Investments, Debt and Equity Securities [Abstract]
Marketable Securities	(3) Marketable Securities The Company’s marketable securities are all classified as available-for-sale within “Current Assets” in the Company’s Consolidated Balance Sheets. FASB has established three levels of inputs that may be used to measure fair value: Level 1 Level 2 Level 3 The Company’s marketable securities valued using Level 1 inputs include highly liquid equity securities, for which quoted market prices are available. The Company’s bond and commercial paper portfolio is valued using a combination of pricing for similar securities, recently executed transactions, cash flow models with yield curves and other pricing models utilizing observable inputs, which are considered Level 2 inputs. For Level 2 investment valuation, the Company utilizes standard pricing procedures of its investment advisory firm which includes various third-party pricing services. These procedures also require specific price monitoring practices as well as pricing review reports, valuation oversight and pricing challenge procedures to maintain the most accurate representation of investment fair market value. The Company accrues interest on its bond and commercial paper portfolio throughout the life of each bond and commercial paper held. Dividends from the equity securities are recognized as received. Interest, dividends and unrealized gains and losses on equity securities are recognized in “Investment income (loss) and interest expense” on the Company’s Consolidated Statements of Income. The Company recognized investment gain of $2.5 million in the thirteen weeks ended April 1, 2023, which included an unrealized gain in equity securities of $325 thousand. In the thirteen weeks ended March 26, 2022, the Company recognized investment income of $632 thousand, which included an unrealized loss in equity securities of $214 thousand. ​ ​ Marketable securities, as of April 1, 2023 and December 31, 2022, consisted of: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Gross ​ Gross ​ ​ ​ (amounts in thousands) ​ Amortized ​ Unrealized ​ Unrealized ​ Fair April 1, 2023 Cost Holding Gains Holding Losses Value Available-for-sale: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Level 1 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Equity securities ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ $ 5,510 Level 2 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Corporate and municipal bonds ​ $ 195,913 ​ $ 2,402 ​ $ (8,863) ​ ​ 189,452 Commercial Paper ​ ​ 19,258 ​ ​ 9 ​ ​ — ​ ​ 19,267 Total ​ $ 215,171 ​ $ 2,411 ​ $ (8,863) ​ $ 214,229 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Gross ​ Gross ​ ​ ​ (amounts in thousands) ​ Amortized ​ Unrealized ​ Unrealized ​ Fair December 31, 2022 Cost Holding Gains Holding Losses Value Available-for-sale: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Level 1 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Equity securities ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ $ 5,185 Level 2 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Corporate and municipal bonds ​ $ 190,025 ​ $ 2,110 ​ $ (10,901) ​ ​ 181,234 Total ​ $ 190,025 ​ $ 2,110 ​ $ (10,901) ​ $ 186,419 ​ ​ Maturities of marketable securities classified as available-for-sale at April 1, 2023, were as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Amortized ​ Fair (amounts in thousands) Cost Value Available-for-sale: ​ ​ ​ ​ ​ ​ Due within one year ​ $ 71,075 ​ $ 69,457 Due after one year through five years ​ ​ 93,453 ​ ​ 90,959 Due after five years through ten years ​ ​ 26,089 ​ ​ 23,927 Due after ten years ​ ​ 24,554 ​ ​ 24,376 Total ​ $ 215,171 ​ $ 208,719 ​ ​ SERP Investments The Company also maintains a non-qualified supplemental executive retirement plan for certain of its associates which allows them to defer income to future periods. Participants in the plans earn a return on their deferrals based on mutual fund investments. The Company chooses to invest in the underlying mutual fund investments to offset the liability associated with the non-qualified deferred compensation plans. Such investments are reported on the Company’s Consolidated Balance Sheets as “SERP investment,” are classified as trading securities and are measured at fair value using Level 1 inputs with gains and losses included in “Investment income (loss) and interest expense” on the Company’s Consolidated Statements of Income. The Company recognized investment income of $1.3 million in the thirteen weeks ended April 1, 2023, and investment loss of $1.5 million in the same period in 2022. The changes in the underlying liability to the associates are recorded in “Other income (expense).”

Leases	(7) Leases As of April 1, 2023, the Company leased approximately 49% of its open store facilities under operating leases that expire at various dates through 2036, with the remaining store facilities being owned. These leases generally provide for fixed annual rentals; however, several provide for minimum annual rentals plus variable lease costs related to real estate taxes and insurance as well as contingent rentals based on a percentage of annual sales or increases periodically based on inflation. These variable lease costs are not included in the measurement of the operating lease right-to-use assets or lease liabilities and are charged to the related expense category included in “Operating, general and administrative expenses.” Most of the leases contain multiple renewal options, under which the Company may extend the lease terms from The Company leases or subleases space to tenants in owned, vacated and open store facilities. Rental income is recorded when earned as a component of “Operating, general and administrative expenses.” The following is a schedule of the lease costs included in “Operating, general and administrative expenses” for the thirteen weeks ended April 1, 2023, and March 26, 2022. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ 13 Weeks Ended (amounts in thousands) April 1, 2023 ​ ​ March 26, 2022 Operating lease cost ​ $ 11,792 ​ $ 11,378 Variable lease cost ​ ​ 2,839 ​ ​ 2,827 Lease or sublease income ​ ​ (2,481) ​ ​ (2,383) Net lease cost ​ $ 12,150 ​ $ 11,822 ​
