Accounting Policies [Abstract]
Description of Business	(1) Description of Business Big 5 Sporting Goods Corporation (the “Company”) is a leading sporting goods retailer in the western United States, operating 430 stores and an e-commerce platform as of October 1, 2023 . The Company provides a full-line product offering in a traditional sporting goods store format that averages approximately 12,000 square feet. The Company’s product mix includes athletic shoes, apparel and accessories, as well as a broad selection of outdoor and athletic equipment for team sports, fitness, camping, hunting, fishing, home recreation, tennis, golf, and winter and summer recreation. The Company is a holding company that operates as one reportable segment through Big 5 Corp., its 100 %-owned subsidiary, and Big 5 Services Corp., which is a 100 %-owned subsidiary of Big 5 Corp. Big 5 Services Corp. provides a centralized operation for the issuance and administration of gift cards and returned merchandise credits (collectively, “stored-value cards”). The accompanying interim unaudited condensed consolidated financial statements (“Interim Financial Statements”) of the Company and its 100%-owned subsidiaries have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and are presented in accordance with the requirements of Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, these Interim Financial Statements do not include all of the information and notes required by GAAP for complete financial statements. These Interim Financial Statements should be read in conjunction with the consolidated financial statements and notes thereto for the fiscal year ended January 1, 2023 included in the Company’s Annual Report on Form 10-K. In the opinion of management, the Interim Financial Statements included herein contain all adjustments, including normal recurring adjustments, considered necessary to present fairly the Company’s financial position, the results of operations and cash flows for the periods presented. The operating results and cash flows of the interim periods presented herein are not necessarily indicative of the results to be expected for any other interim period or the full year.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	(2) Summary of Significant Accounting Policies Consolidation The accompanying Interim Financial Statements include the accounts of Big 5 Sporting Goods Corporation, Big 5 Corp. and Big 5 Services Corp. Intercompany balances and transactions have been eliminated in consolidation. Reporting Period The Company follows the concept of a 52 - 53 week fiscal year, which ends on the Sunday nearest December 31. Fiscal year 2023 is comprised of 52 weeks and ends on December 31, 2023. Fiscal year 2022 was comprised of 52 weeks and ended on January 1, 2023. The interim periods in fiscal 2023 and 2022 are each comprised of 13 weeks. Recently Issued Accounting Updates In May 2023, the Securities and Exchange Commission (“SEC”) adopted the final rule under SEC Release No. 34-97424, Share Repurchase Disclosure Modernization , requiring disclosures related to issuers’ share repurchases that will provide investors with enhanced information to assess the purposes and effects of the repurchases. Disclosure requirements under this rule will be effective in the fourth quarter of fiscal 2023. We do not expect the adoption of this final rule to have a material impact on our results of operations, liquidity or capital resources. In June 2023, the SEC approved new listing standards that were proposed by the New York Stock Exchange and Nasdaq. The new listing standards require listed companies to adopt and comply with a written policy providing for the recovery, in the event of a required accounting restatement, of incentive-based compensation received by current or former executive officers where that compensation is based on erroneously reported financial information. The listing standards took effect on October 2, 2023 and registrants will have until December 1, 2023 (60 days after the effective date) to adopt a recovery policy. The recovery policy must, however, apply to erroneously awarded incentive-based compensation received (as defined in the listing standards) after the effective date. We do not expect the adoption of these new listing standards to have a material impact on our results of operations, liquidity or capital resources. In July 2023, the SEC adopted the final rule under SEC Release Nos. 33-11216, Cybersecurity Risk Management, Strategy, Governance, and Incident Disclosure, requiring current disclosure about material cybersecurity incidents; periodic disclosures about a registrant’s processes to assess, identify, and manage material cybersecurity risks; a description of management’s role in assessing and managing material cybersecurity risks; and the board of directors’ oversight of cybersecurity risks. While the incident-reporting requirements under this rule will be effective in the second quarter of fiscal 2024 due to the Company’s status as a smaller-reporting company, the disclosure requirements under this rule will be effective in the fourth quarter of fiscal 2023. We do not expect the adoption of this final rule to have a material impact on our results of operations, liquidity or capital resources. Other recently issued accounting updates are not expected to have a material impact on the Company’s Interim Financial Statements. General Concentration of Risk The Company purchases merchandise from nearly 700 suppliers, and the Company’s 20 largest suppliers accounted for 35.9 % of total purchases in fiscal 2022. No vendor represented greater than 5 % of total purchases in fiscal 2022. A substantial amount of the Company’s inventory is manufactured abroad and, from time to time, shipping ports may experience capacity constraints (such as delays associated with the novel coronavirus “COVID-19”), labor strikes, work stoppages or other disruptions that may delay the delivery of imported products. A contract dispute may lead to protracted delays in the movement of the Company’s products, which could further delay the delivery of products to the Company’s stores and impact net sales and profitability. In addition, other conditions outside of the Company’s control, such as adverse weather conditions or acts of terrorism or war, such as the current conflict in Ukraine, could significantly disrupt operations at shipping ports or otherwise impact transportation of the imported merchandise we sell, either through supply chain disruptions, or rising freight and fuel costs. Use of Estimates Management makes a number of estimates and assumptions relating to the reporting of assets, liabilities and stockholders’ equity and the disclosure of contingent assets and liabilities at the date of the Interim Financial Statements and reported amounts of revenue and expense during the reporting period to prepare these Interim Financial Statements in conformity with GAAP. Certain items subject to such estimates and assumptions include the carrying amount of merchandise inventories, property and equipment, lease assets and lease liabilities; valuation allowances for receivables, sales returns and deferred income tax assets; estimates related to stored-value cards and the valuation of share-based compensation awards; and obligations related to litigation, self-insurance liabilities and employee benefits. Due to the inherent uncertainty involved in making assumptions and estimates, events and changes in circumstances arising after October 1, 2023 may result in actual outcomes that differ from those contemplated by management’s assumptions and estimates. Revenue Recognition The Company operates solely as a sporting goods retailer, which includes both retail stores and an e-commerce platform, that offers a broad range of products in the western United States and online. Generally, all revenue is recognized when control of the promised goods is transferred to customers, for an amount that reflects the consideration in exchange for those goods. Accordingly, the Company implicitly enters into a contract with customers to deliver merchandise inventory at the point of sale. Collectability is probable since the Company only extends immaterial credit purchases to certain municipalities and local school districts. In accordance with Accounting Standards Codification (“ASC”) 606, Revenue from Contracts with Customers , the Company disaggregates net sales into the following major merchandise categories to depict the nature and amount of revenue and related cash flows: 13 Weeks Ended 39 Weeks Ended October 1, October 2, October 1, October 2, (In thousands) Hardgoods $ 141,108 $ 152,646 $ 375,105 $ 423,003 Athletic and sport footwear 58,292 64,215 170,397 187,604 Athletic and sport apparel 39,006 43,411 138,331 143,095 Other sales 1,483 1,173 4,562 3,524 Net sales $ 239,889 $ 261,445 $ 688,395 $ 757,226 Substantially all of the Company’s revenue is for single performance obligations for the following distinct items: • Retail store sales • E-commerce sales • Stored-value cards For performance obligations related to retail store and e-commerce sales contracts, the Company typically transfers control, for retail stores, upon consummation of the sale when the product is paid for and taken by the customer and, for e-commerce sales, when the product is tendered for delivery to the common carrier. For performance obligations related to stored-value cards, the Company typically transfers control upon redemption of the stored-value card through consummation of a future sales transaction. The Company accounts for shipping and handling relative to e-commerce sales as fulfillment activities, and not a separate performance obligation. Accordingly, the Company recognizes revenue for only one performance obligation, the sale of the product, at shipping point (when the customer gains control). Revenue associated with e-commerce sales was not material for the 13 and 39 weeks ended October 1, 2023 and October 2, 2022. The Company recognized $ 1.2 million and $ 4.3 million in stored-value card redemption revenue for the 13 and 39 weeks ended October 1, 2023 , respectively, compared to $ 1.3 million and $ 4.6 million in stored-value card redemption revenue for the 13 and 39 weeks ended October 2, 2022, respectively. The Company also recognized $ 0.1 million and $ 0.2 million in stored-value card breakage revenue for the 13 and 39 weeks ended October 1, 2023 , respectively, compared to $ 0.1 million and $ 0.2 million in stored-value card breakage revenue for the 13 and 39 weeks ended October 2, 2022, respectively. The Company had outstanding stored-value card liabilities of $ 8.1 million and $ 8.8 million as of October 1, 2023 and January 1, 2023 , respectively, which are included in accrued expenses in the accompanying interim unaudited condensed consolidated balance sheets. Based upon historical experience, stored-value cards are predominantly redeemed in the first two years following their issuance date. In the accompanying interim unaudited condensed consolidated balance sheets, the Company recorded, as prepaid expense, estimated right-of-return merchandise cost of $ 0.7 million and $ 1.2 million related to estimated sales returns as of October 1, 2023 and January 1, 2023, respectively, and recorded, in accrued expenses, an allowance for sales returns reserve of $ 1.4 million and $ 2.3 million as of October 1, 2023 and January 1, 2023 , respectively. Share-Based Compensation The Company accounts for its share-based compensation in accordance with ASC 718, Compensation—Stock Compensation . The Company recognizes compensation expense on a straight-line basis over the requisite service period using the fair-value method for share option awards, nonvested share awards and nonvested share unit awards granted with service-only conditions. See Note 10 to the Interim Financial Statements for a further discussion on share-based compensation. Cash and Cash Equivalents Cash and cash equivalents consist of cash on hand and highly-liquid investments of excess cash into U.S. Treasury bills, which have original maturities of three months or less. See Note 3 to the Interim Financial Statements for a further discussion on the fair value of U.S. Treasury bills. Book overdrafts are classified as current liabilities in the Company’s interim unaudited condensed consolidated balance sheets. Valuation of Merchandise Inventories, Net The Company’s merchandise inventories are valued at the lower of cost or net realizable value using the weighted-average cost method that approximates the first-in, first-out (“FIFO”) method. Average cost includes the direct purchase price of merchandise inventory, net of vendor allowances and cash discounts, in-bound freight-related expense and allocated overhead expense associated with the Company’s distribution center. Management regularly reviews inventories and records valuation reserves for damaged and defective merchandise, merchandise items with slow-moving or obsolescence exposure and merchandise that has a carrying value that exceeds net realizable value. Because of its merchandise mix, the Company has not historically experienced significant occurrences of obsolescence. Inventory shrinkage is accrued as a percentage of merchandise sales based on historical inventory shrinkage trends. The Company performs physical inventories of its stores at least once per year and cycle counts inventories at its distribution center throughout the year. The reserve for inventory shrinkage primarily represents an estimate for inventory shrinkage for each store since the last physical inventory date through the reporting date. These reserves are estimates, which could vary significantly, either favorably or unfavorably, from actual results if future economic conditions, consumer demand and competitive environments differ from expectations. Valuation of Long-Lived Assets In accordance with ASC 360, Property, Plant, and Equipment , the Company reviews long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Long-lived assets are reviewed for recoverability at the lowest level in which there are identifiable cash flows (“asset group”), usually at the store level. The carrying amount of a store asset group includes stores’ property and equipment, primarily leasehold improvements, and operating lease right-of-use (“ROU”) assets. The carrying amount of a store asset group is not considered recoverable if it exceeds the sum of the undiscounted cash flows expected to result from the use and eventual disposition of the store asset group. Factors that could trigger an impairment review include a current-period operating or cash flow loss combined with a history of operating and cash flow losses, and a projection that demonstrates continuing losses or insufficient income over the remaining reasonably certain lease term associated with the use of a store asset group. Other factors may include an adverse change in the business climate or an adverse action or assessment by a regulator in the market of a store asset group. When stores are identified as having an indicator of impairment, the Company forecasts undiscounted cash flows over the store asset group’s remaining reasonably certain lease term and compares the undiscounted cash flows to the carrying amount of the store asset group. If the store asset group is determined not to be recoverable, then an impairment charge will be recognized in the amount by which the carrying amount of the store asset group exceeds its fair value, determined using discounted cash flow valuation techniques, as contemplated in ASC 820, Fair Value Measurements . The Company determines the cash flows expected to result from the store asset group by projecting future revenue, gross margin and operating expense for each store asset group under evaluation for impairment. The estimates of future cash flows involve management judgment and are based upon assumptions about expected future operating performance. Assumptions used in these forecasts are consistent with internal planning, and include assumptions about sales growth rates, gross margins and operating expense in relation to the current economic environment and the Company’s future expectations, competitive factors in its various markets, inflation, sales trends and other relevant environmental factors that may impact the store under evaluation. The actual cash flows could differ from management’s estimates due to changes in business conditions, operating performance and economic conditions. If economic conditions deteriorate in the markets in which the Company conducts business, or if other negative market conditions develop, the Company may experience additional impairment charges in the future for underperforming stores. The resulting impairment charge, if any, is allocated to the property and equipment, primarily leasehold improvements, and operating lease ROU assets on a pro-rata basis using the relative carrying amounts of those assets. The allocated impairment charge to a long-lived asset is limited to the extent that the impairment charge does not reduce the carrying amount of the long-lived asset below its individual fair value. The estimation of the fair value of an ROU asset involves the evaluation of current market value rental amounts for leases associated with ROU assets. The estimates of current market value rental amounts are primarily based on recent observable market rental data of other comparable retail store locations. The fair value of an ROU asset is measured using a discounted cash flow valuation technique by discounting the estimated current and future market rental values using a property-specific discount rate. The Company did no t recognize any impairment charges in the first nine months of fiscal 2023 or 2022 . Leases In accordance with ASC 842, Leases , the Company determines if an arrangement is a lease at inception. The Company has operating and finance leases for the Company’s retail store facilities, distribution center, corporate offices, information technology (“IT”) systems hardware, and distribution center delivery tractors and equipment. Operating leases are included in operating lease ROU assets and operating lease liabilities, current and noncurrent, on the interim unaudited condensed consolidated balance sheets. Finance leases are included in property and equipment and finance lease liabilities, current and noncurrent, on the interim unaudited condensed consolidated balance sheets. Lease liabilities are calculated using the effective interest method, regardless of classification, while the amortization of ROU assets varies depending upon classification. Finance lease classification results in a front-loaded expense recognition pattern over the lease term which amortizes the ROU asset by recognizing interest expense and amortization expense as separate components of lease expense and calculates the amortization expense component on a straight-line basis. Conversely, operating lease classification results in a straight-line expense recognition pattern over the lease term and recognizes lease expense as a single expense component, which results in amortization of the ROU asset that equals the difference between lease expense and interest expense. Lease expense for finance and operating leases are included in cost of sales or selling and administrative expense, based on the use of the leased asset, on the interim unaudited condensed consolidated statements of operations. Variable payments such as property taxes, insurance and common area maintenance related to triple net leases, as well as certain equipment sales taxes, licenses, fees and repairs, are expensed as incurred, and leases with an initial term of 12 months or less are excluded from minimum lease payments and are not recorded on the interim unaudited condensed consolidated balance sheets. The Company recognizes variable lease expense for these short-term leases on a straight-line basis over the remaining lease term. ROU assets represent the right to use an underlying asset for the lease term and operating lease liabilities represent the obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at the commencement date based on the present value of lease payments over the reasonably certain lease term. As the Company’s leases generally do not provide an implicit rate, the Company uses a collateralized incremental borrowing rate (“IBR”) to determine the present value of lease payments. The collateralized IBR is based on a synthetic credit rating that is externally prepared on an annual basis. This analysis considers qualitative and quantitative factors based on guidance provided by a rating agency for the consumer durables industry. The Company adjusts the selected IBR quarterly with a company-specific unsecured yield curve that approximates the Company’s market risk profile. The collateralized IBR is also based upon the estimated impact that the collateral has on the IBR. To account for the collateralized nature of the IBR, the Company utilized a notching method based on notching guidance provided by a rating agency whereby the Company’s base credit rating is notched upward as the yield curve on a secured loan is expected to be lower versus an unsecured loan. The operating lease ROU asset also includes any prepaid lease payments made and is reduced by lease incentives such as tenant improvement allowances. The operating lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Operating lease expense for lease payments is recognized on a straight-line basis over the lease term. Certain of the leases for the Company’s retail store facilities provide for payments based on future sales volumes at the leased location, which are not measurable at the inception of the lease. Under ASC 842, these contingent rents are expensed as they accrue. See Note 5 to the Interim Financial Statements for a further discussion on leases.

Fair Value Measurements

Fair Value Measurements	9 Months Ended

Fair Value Disclosures [Abstract]
Fair Value Measurements	(3) Fair Value Measurements The carrying values of cash and cash equivalents, accounts receivable, accounts payable and accrued expenses approximate the fair values of these instruments due to their short-term nature. Cash equivalents consist of highly-liquid investments of excess cash into U.S. Treasury bills, which have original maturities of three months or less. As of October 1, 2023 and January 1, 2023 , the Company had no cash equivalents, and as of October 2, 2022 , the Company recorded $ 10.0 million in cash equivalents and classified these assets as Level 1 inputs, which are quoted prices (unadjusted) in active markets for identical assets that the Company can access at the measurement date. The Company records these cash equivalents monthly based on the prevailing market interest rate as of the measurement date. Book overdrafts for checks outstanding are classified as current liabilities in the Company’s interim unaudited condensed consolidated balance sheets. The carrying amount for borrowings, if any, under the Company’s credit facility approximates fair value because of the variable market interest rate charged to the Company for these borrowings. When the Company recognizes impairment on certain of its underperforming stores, the carrying values of these stores are reduced to their estimated fair values. The Company’s only significant assets or liabilities measured at fair value on a nonrecurring basis subsequent to their initial recognition were assets subject to long-lived asset impairment related to certain underperforming stores. The Company estimates the fair values of these long-lived assets based on the Company’s own judgments about the assumptions that market participants would use in pricing the asset and on observable real estate market data of underperforming stores’ specific comparable markets, when available. The Company classifies these fair value measurements as Level 3 inputs, which are unobservable inputs for which market data are not available and that are developed using the best information available about pricing assumptions used by market participants in accordance with ASC 820. As of October 1, 2023 and January 1, 2023 , there were no long-lived assets subject to impairment .

Lease Commitments	(5) Lease Commitments The Company has operating and finance leases for the Company’s retail store facilities, distribution center, corporate offices, IT systems hardware, and distribution center delivery tractors and equipment, and accounts for these leases in accordance with ASC 842. Certain of the leases for the Company’s retail store facilities provide for variable payments for property taxes, insurance, common area maintenance payments related to triple net leases, rental payments based on future sales volumes at the leased location, as well as certain equipment sales taxes, licenses, fees and repairs, which are not measurable at the inception of the lease, or rental payments that are adjusted periodically for inflation. The Company recognizes variable lease expense for these leases in the period incurred which, for contingent rent, begins in the period in which it becomes probable that the specified target that triggers the variable lease payments will be achieved. The Company’s lease agreements do not contain any material residual value guarantees or material restrictive covenants.

Long-Term Debt

Long-Term Debt	9 Months Ended

Debt Disclosure [Abstract]
Long-Term Debt	(6) Long-Term Debt The Company, Big 5 Corp. and Big 5 Services Corp. are parties to a Loan, Guaranty and Security Agreement with Bank of America, N.A. (“BofA”), as agent and lender , which was amended on November 22, 2021, October 19, 2022 and May 16, 2023 (as so amended, the “Loan Agreement”). The Loan Agreement has a maturity date of February 24, 2026 and provides for a revolving credit facility with an aggregate committed availability of up to $ 150.0 million. The Company may also request additional increases in aggregate availability, up to a maximum of $ 200.0 million, in which case the existing lender under the Loan Agreement will have the option to increase the commitment to accommodate the requested increase. If such existing lender does not exercise that option, the Company may (with the consent of BofA in its role as the administrative agent, not to be unreasonably withheld) seek other lenders willing to provide such commitments. The credit facility includes a $ 50.0 million sublimit for issuances of letters of credit. The Company may borrow under the Loan Agreement from time to time, provided the amounts outstanding will not exceed the lesser of the then aggregate committed availability (as discussed above) and the Borrowing Base (such lesser amount being referred to as the “Line Cap”). As defined in the Loan Agreement, the “Borrowing Base” generally is comprised of the sum, at the time of calculation, of (a) 90.00 % of eligible credit card receivables; plus (b) the cost of eligible inventory (other than eligible in-transit inventory), net of inventory reserves, multiplied by 90.00 % of the appraised net orderly liquidation value of eligible inventory (expressed as a percentage of the cost of eligible inventory); plus (c) the cost of eligible in-transit inventory, net of inventory reserves, multiplied by 90.00 % of the appraised net orderly liquidation value of eligible in-transit inventory (expressed as a percentage of the cost of eligible in-transit inventory), minus (d) certain agreed-upon reserves as well as other reserves established by BofA in its role as the administrative agent in its reasonable discretion. Generally, the Company may designate specific borrowings under the Loan Agreement as either base rate loans or Term SOFR rate loans. The applicable interest rate on the Company’s borrowings is a function of the daily average, over the preceding fiscal quarter, of the excess of the Line Cap over amounts borrowed (such amount being referred to as the “Average Daily Availability”). Those loans designated as Term SOFR rate loans bear interest at a rate equal to the then applicable secured overnight financing rate as administered by the Federal Reserve Bank of New York (“ SOFR”) rate plus a 0.10 % “SOFR adjustment” spread, plus an applicable margin as shown in the table below. Those loans designated as base rate loans bear interest at a rate equal to the applicable margin for base rate loans (as shown below) plus the highest of (a) the Federal funds rate, as in effect from time to time, plus one-half of one percent ( 0.50 %), (b) the one-month SOFR rate, plus one percentage point ( 1.00 %), or (c) the rate of interest in effect for such day as announced from time to time within BofA as its “prime rate.” The applicable margin for all loans is a function of Average Daily Availability for the preceding fiscal quarter as set forth below. Level Average Daily Availability SOFR Rate Margin Base Rate I Greater than or equal to $70,000,000 1.375 % 0.375 % II Less than $70,000,000 1.500 % 0.500 % The commitment fee assessed on the unused portion of the credit facility is 0.20 % per annum. Obligations under the Loan Agreement are secured by a general lien on and security interest in substantially all of the Company’s assets. The Loan Agreement contains covenants that require the Company to maintain a fixed charge coverage ratio of not less than 1.0 :1.0 in certain circumstances, and limits the ability to, among other things, incur liens, incur additional indebtedness, transfer or dispose of assets, change the nature of the business, guarantee obligations, pay dividends or make other distributions or repurchase stock, and make advances, loans or investments. The Company may generally declare or pay cash dividends or repurchase stock only if, among other things, no default or event of default then exists or would arise from such dividend or repurchase of stock and, after giving effect to such dividend or repurchase, certain availability and/or fixed charge coverage ratio requirements are satisfied, although the Company is permitted to make up to $ 5.0 million of dividend payments or stock repurchases per year without satisfaction of the availability or fixed charge coverage ratio requirements, but dividends or stock repurchases made without satisfying the availability and/or fixed charge coverage ratio requirements will require the establishment of an additional reserve that will reduce borrowing availability under the Loan Agreement for 75 days. The Loan Agreement contains customary events of default, including, without limitation, failure to pay when due principal amounts with respect to the credit facility, failure to pay any interest or other amounts under the credit facility, failure to comply with certain agreements or covenants contained in the Loan Agreement, failure to satisfy certain judgments against the Company, failure to pay when due (or any other default which permits the acceleration of) certain other material indebtedness in principal amount in excess of $ 5.0 million, and certain insolvency and bankruptcy events. As of October 1, 2023 and January 1, 2023 , the Company had no long-term revolving credit borrowings outstanding. As of October 1, 2023 and January 1, 2023, the Company had outstanding letter of credit commitments of $ 1.4 million. Total remaining borrowing availability, after subtracting letters of credit, was $ 148.6 million as of October 1, 2023 and January 1, 2023 .

Income Tax Disclosure [Abstract]
Income Taxes	(7) Income Taxes Under the asset and liability method prescribed under ASC 740, Income Taxes , the Company recognizes deferred tax assets and liabilities for the future tax consequences attributable to differences between financial statement carrying amounts of assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be realized or settled. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the enactment date. The realizability of deferred tax assets is assessed throughout the year and a valuation allowance is recorded, if necessary, to reduce net deferred tax assets to the amount more likely than not to be realized. As of October 1, 2023 and January 1, 2023, the Company had a valuation allowance for deferred income tax assets of $ 0.2 million related to unused California Enterprise Zone Tax Credits, which the Company will no longer be able to carry forward beyond 2024 as a result of California’s termination of this program. The Company files a consolidated federal income tax return and files tax returns in various state and local jurisdictions. The statutes of limitations for consolidated federal income tax returns are open for fiscal years 2019 and after, and state and local income tax returns are open for fiscal years 2018 and after. As of October 1, 2023 and January 1, 2023 , the Company had no unrecognized tax benefits including those that, if recognized, would affect the Company’s effective income tax rate over the next 12 months . The Company’s policy is to recognize interest accrued related to unrecognized tax benefits in interest expense and penalties in operating expense. As of October 1, 2023 and January 1, 2023 , the Company had no accrued interest or penalties.

Earnings Per Share

Earnings Per Share [Abstract]
Earnings Per Share	(8) Earnings Per Share The Company calculates earnings per share in accordance with ASC 260, Earnings Per Share , which requires a dual presentation of basic and diluted earnings per share. Basic earnings per share is calculated by dividing net income by the weighted-average shares of common stock outstanding, reduced by shares repurchased and held in treasury, during the period. Diluted earnings per share represents basic earnings per share adjusted to include the potentially dilutive effect of outstanding share option awards, nonvested share awards and nonvested share unit awards. During periods of net loss, diluted loss per share is equal to basic loss per share because the antidilutive effect of potential common shares is disregarded. The following table sets forth the computation of basic and diluted earnings per common share: 13 Weeks Ended 39 Weeks Ended October 1, October 2, October 1, October 2, (In thousands, except per share data) Net income $ 1,858 $ 6,369 $ 1,769 $ 24,406 Weighted-average shares of common stock Basic 21,801 21,586 21,731 21,647 Dilutive effect of common stock equivalents 244 344 272 474 Diluted 22,045 21,930 22,003 22,121 Basic earnings per share $ 0.09 $ 0.30 $ 0.08 $ 1.13 Diluted earnings per share $ 0.08 $ 0.29 $ 0.08 $ 1.10 Antidilutive share option awards excluded from 20 20 20 15 Antidilutive nonvested share awards excluded 276 389 310 172 The computation of diluted earnings per share for all periods presented excludes certain share option awards that were outstanding and antidilutive (i.e., including such share option awards would result in higher earnings per share) since the exercise prices of these share option awards exceeded the average market price of the Company’s common shares. The computation of diluted earnings per share for all periods presented excludes certain nonvested share awards that were outstanding and antidilutive since the grant date fair values of these nonvested share awards exceeded the average market price of the Company’s common shares.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	(9) Commitments and Contingencies Recovery of Insurance Proceeds In the fourth quarter of fiscal 2022, one of the Company’s stores qualified for loss recovery claims due to property damage sustained as a result of a roof collapse, and the Company disposed of assets of approximately $ 0.4 million related to lost inventory and property and equipment. In the third quarter of fiscal 2023, the Company reached an agreement with its insurance carrier and, after application of a deductible of $ 0.5 million, the Company received a cash insurance recovery of $ 0.7 million in total, of which $ 0.6 million related to the reimbursement of lost inventory and profit margin and $ 0.1 million related to the reimbursement of property and equipment. Accordingly, the Company recognized a gain of $ 0.3 million related to the recovery of lost inventory and profit margin and a gain of $ 21,000 related to the recovery of property and equipment. The gain related to the recovery of lost inventory and profit margin is included in the accompanying interim unaudited condensed consolidated statement of operations as a reduction to cost of goods sold and the gain related to the recovery of lost property and equipment is included in the accompanying interim unaudited condensed consolidated statement of operations as a reduction to selling and administrative expense for fiscal 2023. Legal Proceedings On March 13, 2023, a complaint was filed in the Superior Court of the State of California, County of Santa Clara, entitled Zareyah Thompson v. Big 5 Corp., et. al., Case No. 23CV412334 (“Thompson Complaint”). The Thompson Complaint was brought as a purported California Private Attorneys General Act (“PAGA”) action on behalf of “current and former employees who worked for the Company or its operating subsidiary in California as a non-exempt, hourly paid employee and received at least one wage statement.” The Thompson Complaint alleges, among other things, that Big 5 failed to (i) provide minimum wages, (ii) provide compliant meal or rest periods, (iii) maintain and provide accurate itemized wage statements, (iv) properly compensate for all time worked, including overtime, premium, vacation and final wages, (v) properly maintain payroll records, and (vi) provide suitable seating. On March 21, 2023, a second complaint was filed in the Superior Court of the State of California, County of Santa Clara, entitled Christopher Puga v. Big 5 Corp., et. al., Case No. 23CV412953 (“Puga Complaint”). The Puga Complaint was brought as a purported PAGA action on behalf of “all current and former non-exempt employees that worked either directly or via a staffing agency for the Company or its operating subsidiary at any location in California” (“Putative Covered Employees”). The Puga Complaint alleges, among other things, that Big 5 (i) unlawfully required Putative Covered Employees to agree to unlawful criminal background checks, (ii) conducted unlawful financial and criminal background checks, and did not (iii) provide minimum wages, (iv) provide accurate itemized wage statements, (v) maintain accurate records pertaining to the Putative Covered Employees’ employment, (vi) produce or make available Putative Covered Employees’ personnel records and/or payroll records, (vii) provide compliant meal or rest periods, (viii) properly compensate for all time worked, including overtime, premium, vacation, and final wages, (ix) reimburse necessary business expenses; (x) provide suitable seating; (xi) provide sick leave pay to Putative Covered Employees, (xii) accurately calculate sick leave accrual and rate of pay, (xiii) put the Putative Covered Employees on notice of their paid sick leave rights, and (xiv) provide supplemental paid sick leave. The Thompson and Puga complaints have many overlapping causes of action. Accordingly, on or about April 12, 2023, a notice of related cases was filed with the Court regarding the Thompson Complaint and Puga Complaint. The Court subsequently conducted a case management conference on June 29, 2023 for both complaints, and jointly coordinated the complaints. The Company’s counsel held a mediation with opposing counsel on September 27, 2023. The Company has reached a tentative settlement in both cases and established a cumulative indemnity reserve of $ 1.5 million. Any settlement finalized will be subject to Court approval. The Company is involved in various other claims and legal actions arising in the ordinary course of business. In the opinion of management, the ultimate disposition of these matters is not expected to have a material effect on the Company’s results of operations, financial condition or cash flows.

Share-Based Payment Arrangement [Abstract]
Share-based Compensation	(10) Share-based Compensation In June 2022, the Company amended and restated its 2019 Equity Incentive Plan (the “2019 Plan”), primarily authorizing an additional 3,300,000 shares available for future grant. As of October 1, 2023, 3,549,208 shares remained registered and available for future grant under the 2019 Plan. At its discretion, the Company grants share option awards, nonvested share awards and nonvested share unit awards to certain employees, as defined by ASC 718, Compensation—Stock Compensation , under the Company’s 2019 Plan, and accounts for its share-based compensation in accordance with ASC 718. The Company recognized $ 0.7 million and $ 2.1 million in share-based compensation expense for the 13 and 39 weeks ended October 1, 2023 , respectively, compared to $ 0.6 million and $ 1.8 million in share-based compensation expense for the 13 and 39 weeks ended October 2, 2022, respectively. Share Option Awards Share option awards granted by the Company generally vest and become exercisable in four equal annual installments of 25 % per year with a maximum life of ten years . The exercise price of share option awards is equal to the quoted market price of the Company’s common stock on the date of grant. No share option awards were granted in the first nine months of fiscal 2023 . The Company granted 10,000 share option awards in the first nine months of fiscal 2022 with a weighted-average grant-date fair value of $ 5.46 per share option award. A summary of the status of the Company’s share option awards is presented below: Shares Weighted- Weighted- Aggregate Outstanding at January 1, 2023 300,035 $ 4.24 Exercised ( 36,550 ) 2.99 Forfeited ( 1,500 ) 2.23 Outstanding at October 1, 2023 261,985 $ 4.43 5.91 $ 916,807 Exercisable at October 1, 2023 189,045 $ 3.94 5.57 $ 640,229 Vested and Expected to Vest at October 1, 2023 261,844 $ 4.43 5.91 $ 916,563 The aggregate intrinsic value represents the total pretax intrinsic value, based upon the Company’s most recent closing stock price of $ 7.01 as of October 1, 2023, which would have been received by the share option award holders had all share option award holders exercised their share option awards as of that date. As of October 1, 2023, there was $ 0.1 million of total unrecognized compensation expense related to share option awards granted. That expense is expected to be recognized over a weighted-average period of 0.8 years. Nonvested Share Awards and Nonvested Share Unit Awards Nonvested share awards granted by the Company vest for employees from the date of grant in four equal annual installments of 25 % per year. Nonvested share awards and nonvested share unit awards granted by the Company to non-employee directors for their service as directors, as defined by ASC 718, generally vest 100 % on the earlier of (a) the date of the Company’s next annual stockholders meeting following the grant date, or (b) the first anniversary of the grant date. Nonvested share awards become outstanding when granted and are delivered to the recipient upon their vesting. Vested share unit awards, including any dividend reinvestments, are delivered to the recipient on the tenth business day of January following the year in which the recipient’s service to the Company is terminated, at which time the units convert to shares and become outstanding. The total fair value of nonvested share awards which vested during the first nine months of fiscal 2023 and 2022 was $ 2.0 million and $ 3.3 million, respectively. No nonvested share unit awards vested during the first nine months of fiscal 2023 and 2022. The Company granted 327,112 and 284,630 nonvested share awards in the first nine months of fiscal 2023 and 2022, respectively. The weighted-average grant-date fair value per share of the Company’s nonvested share awards granted in the first nine months of fiscal 2023 and 2022 was $ 7.91 and $ 15.03 , respectively. No nonvested share unit awards were granted during the periods presented. A summary of the status of the Company’s nonvested share awards is presented below: Shares Weighted- Balance at January 1, 2023 587,675 $ 11.64 Granted 327,112 7.91 Vested ( 250,055 ) 9.65 Forfeited ( 23,670 ) 10.72 Balance at October 1, 2023 641,062 $ 10.55 To satisfy employee minimum statutory tax withholding requirements for nonvested share awards that vest, the Company withholds and retires a portion of the vesting common shares, unless an employee elects to pay cash. In the first nine months of fiscal 2023 , the Company withheld 80,065 common shares with a total value of $ 0.6 million. This amount is presented as a cash outflow from financing activities in the accompanying interim unaudited condensed consolidated statement of cash flows. As of October 1, 2023, there was $ 5.3 million of total unrecognized compensation expense related to nonvested share awards, which is expected to be recognized over a weighted-average period of 2.4 years. As of October 1, 2023 , there was no remaining unrecognized compensation expense related to nonvested share unit awards.

The interim periods in fiscal 2023 and 2022 are each comprised of 13 weeks.
Recently Issued Accounting Updates	Recently Issued Accounting Updates In May 2023, the Securities and Exchange Commission (“SEC”) adopted the final rule under SEC Release No. 34-97424, Share Repurchase Disclosure Modernization , requiring disclosures related to issuers’ share repurchases that will provide investors with enhanced information to assess the purposes and effects of the repurchases. Disclosure requirements under this rule will be effective in the fourth quarter of fiscal 2023. We do not expect the adoption of this final rule to have a material impact on our results of operations, liquidity or capital resources. In June 2023, the SEC approved new listing standards that were proposed by the New York Stock Exchange and Nasdaq. The new listing standards require listed companies to adopt and comply with a written policy providing for the recovery, in the event of a required accounting restatement, of incentive-based compensation received by current or former executive officers where that compensation is based on erroneously reported financial information. The listing standards took effect on October 2, 2023 and registrants will have until December 1, 2023 (60 days after the effective date) to adopt a recovery policy. The recovery policy must, however, apply to erroneously awarded incentive-based compensation received (as defined in the listing standards) after the effective date. We do not expect the adoption of these new listing standards to have a material impact on our results of operations, liquidity or capital resources. In July 2023, the SEC adopted the final rule under SEC Release Nos. 33-11216, Cybersecurity Risk Management, Strategy, Governance, and Incident Disclosure, requiring current disclosure about material cybersecurity incidents; periodic disclosures about a registrant’s processes to assess, identify, and manage material cybersecurity risks; a description of management’s role in assessing and managing material cybersecurity risks; and the board of directors’ oversight of cybersecurity risks. While the incident-reporting requirements under this rule will be effective in the second quarter of fiscal 2024 due to the Company’s status as a smaller-reporting company, the disclosure requirements under this rule will be effective in the fourth quarter of fiscal 2023. We do not expect the adoption of this final rule to have a material impact on our results of operations, liquidity or capital resources. Other recently issued accounting updates are not expected to have a material impact on the Company’s Interim Financial Statements.
COVID-19 Impact on Concentration of Risk	General Concentration of Risk The Company purchases merchandise from nearly 700 suppliers, and the Company’s 20 largest suppliers accounted for 35.9 % of total purchases in fiscal 2022. No vendor represented greater than 5 % of total purchases in fiscal 2022. A substantial amount of the Company’s inventory is manufactured abroad and, from time to time, shipping ports may experience capacity constraints (such as delays associated with the novel coronavirus “COVID-19”), labor strikes, work stoppages or other disruptions that may delay the delivery of imported products. A contract dispute may lead to protracted delays in the movement of the Company’s products, which could further delay the delivery of products to the Company’s stores and impact net sales and profitability. In addition, other conditions outside of the Company’s control, such as adverse weather conditions or acts of terrorism or war, such as the current conflict in Ukraine, could significantly disrupt operations at shipping ports or otherwise impact transportation of the imported merchandise we sell, either through supply chain disruptions, or rising freight and fuel costs.
Use of Estimates	Use of Estimates Management makes a number of estimates and assumptions relating to the reporting of assets, liabilities and stockholders’ equity and the disclosure of contingent assets and liabilities at the date of the Interim Financial Statements and reported amounts of revenue and expense during the reporting period to prepare these Interim Financial Statements in conformity with GAAP. Certain items subject to such estimates and assumptions include the carrying amount of merchandise inventories, property and equipment, lease assets and lease liabilities; valuation allowances for receivables, sales returns and deferred income tax assets; estimates related to stored-value cards and the valuation of share-based compensation awards; and obligations related to litigation, self-insurance liabilities and employee benefits. Due to the inherent uncertainty involved in making assumptions and estimates, events and changes in circumstances arising after October 1, 2023 may result in actual outcomes that differ from those contemplated by management’s assumptions and estimates.
Revenue Recognition	Revenue Recognition The Company operates solely as a sporting goods retailer, which includes both retail stores and an e-commerce platform, that offers a broad range of products in the western United States and online. Generally, all revenue is recognized when control of the promised goods is transferred to customers, for an amount that reflects the consideration in exchange for those goods. Accordingly, the Company implicitly enters into a contract with customers to deliver merchandise inventory at the point of sale. Collectability is probable since the Company only extends immaterial credit purchases to certain municipalities and local school districts. In accordance with Accounting Standards Codification (“ASC”) 606, Revenue from Contracts with Customers , the Company disaggregates net sales into the following major merchandise categories to depict the nature and amount of revenue and related cash flows: 13 Weeks Ended 39 Weeks Ended October 1, October 2, October 1, October 2, (In thousands) Hardgoods $ 141,108 $ 152,646 $ 375,105 $ 423,003 Athletic and sport footwear 58,292 64,215 170,397 187,604 Athletic and sport apparel 39,006 43,411 138,331 143,095 Other sales 1,483 1,173 4,562 3,524 Net sales $ 239,889 $ 261,445 $ 688,395 $ 757,226 Substantially all of the Company’s revenue is for single performance obligations for the following distinct items: • Retail store sales • E-commerce sales • Stored-value cards For performance obligations related to retail store and e-commerce sales contracts, the Company typically transfers control, for retail stores, upon consummation of the sale when the product is paid for and taken by the customer and, for e-commerce sales, when the product is tendered for delivery to the common carrier. For performance obligations related to stored-value cards, the Company typically transfers control upon redemption of the stored-value card through consummation of a future sales transaction. The Company accounts for shipping and handling relative to e-commerce sales as fulfillment activities, and not a separate performance obligation. Accordingly, the Company recognizes revenue for only one performance obligation, the sale of the product, at shipping point (when the customer gains control). Revenue associated with e-commerce sales was not material for the 13 and 39 weeks ended October 1, 2023 and October 2, 2022. The Company recognized $ 1.2 million and $ 4.3 million in stored-value card redemption revenue for the 13 and 39 weeks ended October 1, 2023 , respectively, compared to $ 1.3 million and $ 4.6 million in stored-value card redemption revenue for the 13 and 39 weeks ended October 2, 2022, respectively. The Company also recognized $ 0.1 million and $ 0.2 million in stored-value card breakage revenue for the 13 and 39 weeks ended October 1, 2023 , respectively, compared to $ 0.1 million and $ 0.2 million in stored-value card breakage revenue for the 13 and 39 weeks ended October 2, 2022, respectively. The Company had outstanding stored-value card liabilities of $ 8.1 million and $ 8.8 million as of October 1, 2023 and January 1, 2023 , respectively, which are included in accrued expenses in the accompanying interim unaudited condensed consolidated balance sheets. Based upon historical experience, stored-value cards are predominantly redeemed in the first two years following their issuance date. In the accompanying interim unaudited condensed consolidated balance sheets, the Company recorded, as prepaid expense, estimated right-of-return merchandise cost of $ 0.7 million and $ 1.2 million related to estimated sales returns as of October 1, 2023 and January 1, 2023, respectively, and recorded, in accrued expenses, an allowance for sales returns reserve of $ 1.4 million and $ 2.3 million as of October 1, 2023 and January 1, 2023 , respectively.
Share-Based Compensation	Share-Based Compensation The Company accounts for its share-based compensation in accordance with ASC 718, Compensation—Stock Compensation . The Company recognizes compensation expense on a straight-line basis over the requisite service period using the fair-value method for share option awards, nonvested share awards and nonvested share unit awards granted with service-only conditions. See Note 10 to the Interim Financial Statements for a further discussion on share-based compensation.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents consist of cash on hand and highly-liquid investments of excess cash into U.S. Treasury bills, which have original maturities of three months or less. See Note 3 to the Interim Financial Statements for a further discussion on the fair value of U.S. Treasury bills. Book overdrafts are classified as current liabilities in the Company’s interim unaudited condensed consolidated balance sheets.
Valuation of Merchandise Inventories, Net	Valuation of Merchandise Inventories, Net The Company’s merchandise inventories are valued at the lower of cost or net realizable value using the weighted-average cost method that approximates the first-in, first-out (“FIFO”) method. Average cost includes the direct purchase price of merchandise inventory, net of vendor allowances and cash discounts, in-bound freight-related expense and allocated overhead expense associated with the Company’s distribution center. Management regularly reviews inventories and records valuation reserves for damaged and defective merchandise, merchandise items with slow-moving or obsolescence exposure and merchandise that has a carrying value that exceeds net realizable value. Because of its merchandise mix, the Company has not historically experienced significant occurrences of obsolescence. Inventory shrinkage is accrued as a percentage of merchandise sales based on historical inventory shrinkage trends. The Company performs physical inventories of its stores at least once per year and cycle counts inventories at its distribution center throughout the year. The reserve for inventory shrinkage primarily represents an estimate for inventory shrinkage for each store since the last physical inventory date through the reporting date. These reserves are estimates, which could vary significantly, either favorably or unfavorably, from actual results if future economic conditions, consumer demand and competitive environments differ from expectations.
Valuation of Long-Lived Assets	Valuation of Long-Lived Assets In accordance with ASC 360, Property, Plant, and Equipment , the Company reviews long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Long-lived assets are reviewed for recoverability at the lowest level in which there are identifiable cash flows (“asset group”), usually at the store level. The carrying amount of a store asset group includes stores’ property and equipment, primarily leasehold improvements, and operating lease right-of-use (“ROU”) assets. The carrying amount of a store asset group is not considered recoverable if it exceeds the sum of the undiscounted cash flows expected to result from the use and eventual disposition of the store asset group. Factors that could trigger an impairment review include a current-period operating or cash flow loss combined with a history of operating and cash flow losses, and a projection that demonstrates continuing losses or insufficient income over the remaining reasonably certain lease term associated with the use of a store asset group. Other factors may include an adverse change in the business climate or an adverse action or assessment by a regulator in the market of a store asset group. When stores are identified as having an indicator of impairment, the Company forecasts undiscounted cash flows over the store asset group’s remaining reasonably certain lease term and compares the undiscounted cash flows to the carrying amount of the store asset group. If the store asset group is determined not to be recoverable, then an impairment charge will be recognized in the amount by which the carrying amount of the store asset group exceeds its fair value, determined using discounted cash flow valuation techniques, as contemplated in ASC 820, Fair Value Measurements . The Company determines the cash flows expected to result from the store asset group by projecting future revenue, gross margin and operating expense for each store asset group under evaluation for impairment. The estimates of future cash flows involve management judgment and are based upon assumptions about expected future operating performance. Assumptions used in these forecasts are consistent with internal planning, and include assumptions about sales growth rates, gross margins and operating expense in relation to the current economic environment and the Company’s future expectations, competitive factors in its various markets, inflation, sales trends and other relevant environmental factors that may impact the store under evaluation. The actual cash flows could differ from management’s estimates due to changes in business conditions, operating performance and economic conditions. If economic conditions deteriorate in the markets in which the Company conducts business, or if other negative market conditions develop, the Company may experience additional impairment charges in the future for underperforming stores. The resulting impairment charge, if any, is allocated to the property and equipment, primarily leasehold improvements, and operating lease ROU assets on a pro-rata basis using the relative carrying amounts of those assets. The allocated impairment charge to a long-lived asset is limited to the extent that the impairment charge does not reduce the carrying amount of the long-lived asset below its individual fair value. The estimation of the fair value of an ROU asset involves the evaluation of current market value rental amounts for leases associated with ROU assets. The estimates of current market value rental amounts are primarily based on recent observable market rental data of other comparable retail store locations. The fair value of an ROU asset is measured using a discounted cash flow valuation technique by discounting the estimated current and future market rental values using a property-specific discount rate. The Company did no t recognize any impairment charges in the first nine months of fiscal 2023 or 2022 .
Leases	Leases In accordance with ASC 842, Leases , the Company determines if an arrangement is a lease at inception. The Company has operating and finance leases for the Company’s retail store facilities, distribution center, corporate offices, information technology (“IT”) systems hardware, and distribution center delivery tractors and equipment. Operating leases are included in operating lease ROU assets and operating lease liabilities, current and noncurrent, on the interim unaudited condensed consolidated balance sheets. Finance leases are included in property and equipment and finance lease liabilities, current and noncurrent, on the interim unaudited condensed consolidated balance sheets. Lease liabilities are calculated using the effective interest method, regardless of classification, while the amortization of ROU assets varies depending upon classification. Finance lease classification results in a front-loaded expense recognition pattern over the lease term which amortizes the ROU asset by recognizing interest expense and amortization expense as separate components of lease expense and calculates the amortization expense component on a straight-line basis. Conversely, operating lease classification results in a straight-line expense recognition pattern over the lease term and recognizes lease expense as a single expense component, which results in amortization of the ROU asset that equals the difference between lease expense and interest expense. Lease expense for finance and operating leases are included in cost of sales or selling and administrative expense, based on the use of the leased asset, on the interim unaudited condensed consolidated statements of operations. Variable payments such as property taxes, insurance and common area maintenance related to triple net leases, as well as certain equipment sales taxes, licenses, fees and repairs, are expensed as incurred, and leases with an initial term of 12 months or less are excluded from minimum lease payments and are not recorded on the interim unaudited condensed consolidated balance sheets. The Company recognizes variable lease expense for these short-term leases on a straight-line basis over the remaining lease term. ROU assets represent the right to use an underlying asset for the lease term and operating lease liabilities represent the obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at the commencement date based on the present value of lease payments over the reasonably certain lease term. As the Company’s leases generally do not provide an implicit rate, the Company uses a collateralized incremental borrowing rate (“IBR”) to determine the present value of lease payments. The collateralized IBR is based on a synthetic credit rating that is externally prepared on an annual basis. This analysis considers qualitative and quantitative factors based on guidance provided by a rating agency for the consumer durables industry. The Company adjusts the selected IBR quarterly with a company-specific unsecured yield curve that approximates the Company’s market risk profile. The collateralized IBR is also based upon the estimated impact that the collateral has on the IBR. To account for the collateralized nature of the IBR, the Company utilized a notching method based on notching guidance provided by a rating agency whereby the Company’s base credit rating is notched upward as the yield curve on a secured loan is expected to be lower versus an unsecured loan. The operating lease ROU asset also includes any prepaid lease payments made and is reduced by lease incentives such as tenant improvement allowances. The operating lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Operating lease expense for lease payments is recognized on a straight-line basis over the lease term. Certain of the leases for the Company’s retail store facilities provide for payments based on future sales volumes at the leased location, which are not measurable at the inception of the lease. Under ASC 842, these contingent rents are expensed as they accrue. See Note 5 to the Interim Financial Statements for a further discussion on leases.
