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 2018 is comprised of 52 weeks and ends on December 30, 2018. Fiscal year 2017 was comprised of 52 weeks and ended on December 31, 2017. The fiscal interim periods in fiscal 2018 and 2017 are each comprised of 13 weeks. Recently Adopted Accounting Updates In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers (Topic 606) Revenue Recognition Recently Issued Accounting Updates In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) Other recently issued accounting updates are not expected to have a material impact on the Company’s consolidated financial statements. Use of Estimates Management has made a number of estimates and assumptions relating to the reporting of assets, liabilities and stockholders’ equity and the disclosure of contingent assets and liabilities as of 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, and property and equipment; valuation allowances for receivables, sales returns and deferred income tax assets; estimates related to gift cards and returned merchandise credits (collectively, “stored-value cards”) and the valuation of share-based compensation awards; and obligations related to litigation, self-insurance liabilities and employee benefits. Actual results could differ significantly from these estimates under different assumptions and conditions. Revenue Recognition On January 1, 2018, the Company adopted Accounting Standards Codification (“ASC”) 606, Revenue from Contracts with Customers, 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 revenues are recognized when control of the promised goods is transferred to customers, in 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. Collectibility is reasonably assured since the Company only extends immaterial credit purchases to certain municipalities and local school districts. As noted in the segment information in the notes to the consolidated financial statements of the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2017 and Note 1 to these Interim Financial Statements, the Company’s business consists of one reportable segment. In accordance with ASC 606, 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 26 Weeks Ended July 1, 2018 July 2, 2017 July 1, 2018 July 2, 2017 (In thousands) Hard goods $ 129,013 $ 132,958 $ 233,464 $ 243,712 Athletic and sport apparel 42,590 41,949 101,036 107,078 Athletic and sport footwear 67,199 67,803 136,552 141,971 Other sales 1,149 961 3,077 3,514 Net sales $ 239,951 $ 243,671 $ 474,129 $ 496,275 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 at a point in time upon redemption of the stored-value card through consummation of a future sales transaction. The transaction price for each contract is the stated price on the product, reduced by any stated discounts at that point in time. The Company does not engage in sales of products that attach a future material right which could result in a separate performance obligation for the purchase of goods in the future at a material discount. The implicit point-of-sale contract with the customer, as reflected in the transaction receipt, states the final terms of the sale, including the description, quantity, and price of each product purchased. Payment for the Company’s contracts is due in full upon delivery. The customer agrees to a stated price implicit in the contract. The transaction price relative to sales subject to a right of return reflects the amount of estimated consideration to which the Company expects to be entitled. This amount of variable consideration included in the transaction price, and measurement of net sales, is included in net sales only to the extent that it is probable that there will be no significant reversal in a future period. Actual amounts of consideration ultimately received may differ from the Company’s estimates. The allowance for sales returns is estimated based upon historical experience and a provision for estimated returns is recorded as a reduction in sales in the relevant period. The estimated right-of-return merchandise cost related to the sales returns is recorded as prepaid expense in the Company’s interim unaudited condensed consolidated balance sheet as of July 1, 2018. If actual results in the future vary from the Company’s estimates, the Company adjusts these estimates, which would affect net sales and earnings in the period such variances become known. The Company has elected to apply the practical expedient, relative to e-commerce sales, which allows an entity to account for shipping and handling 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 is not material. Contract liabilities are recognized primarily for stored-value card sales. Cash received from the sale of stored-value cards is recorded as a contract liability in accrued expenses, and the Company recognizes revenue upon the customer’s redemption of the stored-value card. Stored-value card breakage is recognized as revenue in proportion to the pattern of customer redemptions by applying a historical breakage rate of five percent. The Company does not sell or provide stored-value cards that carry expiration dates. The Company recognized approximately $1.7 million and $3.9 million in stored-value card redemption revenue for the 13 and 26 weeks ended July 1, 2018, respectively, and for the 13 and 26 weeks ended July 2, 2017, respectively. The Company also recognized approximately $88,000 and $206,000 in stored-value card breakage revenue for the 13 and 26 weeks ended July 1, 2018, respectively, compared to approximately $111,000 and $223,000 in stored-value card breakage revenue for the 13 and 26 weeks ended July 2, 2017, respectively. The Company had outstanding stored-value card liabilities of $5.7 million and $7.4 million The Company recorded, as prepaid expense, estimated right-of-return merchandise cost of $0.9 million related to estimated sales returns and an allowance for sales returns reserve of $1.8 million as of July 1, 2018 under ASC 606, which would have been reported as a net liability of $0.9 million with no estimated right-of-return merchandise cost recorded as of July 1, 2018 under ASC 605. Share-Based Compensation The Company accounts for share-based compensation in accordance with ASC 718, Compensation—Stock Compensation Valuation of Merchandise Inventories, Net The Company’s merchandise inventories are made up of finished goods and are valued at the lower of cost or net realizable value using the weighted-average cost method, which approximates the first-in, first-out (“FIFO”) method. Average cost includes the direct purchase price of merchandise inventory, net of certain 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 The Company reviews long-lived assets for recoverability whenever events or changes in circumstances indicate that the carrying amount of an asset may be impaired. 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. Each store typically requires net investments of approximately $0.5 million in long-lived assets to be held and used, subject to recoverability testing. The carrying amount of an 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 asset group. If the 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 asset group exceeds its fair value, determined using discounted cash flow valuation techniques, as defined in ASC 360, Property, Plant, and Equipment The Company determines the sum of the undiscounted cash flows expected to result from the asset group by projecting future revenue, gross margin and operating expense for each store 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 future expectations, competitive factors in the various markets and inflation. The actual cash flows could differ from management’s estimates due to changes in business conditions, operating performance and economic conditions. The Company recognized no impairment charges in the first half of fiscal 2018 or 2017. Leases and Deferred Rent The Company accounts for its leases under the provisions of ASC 840, Leases The Company evaluates and classifies its leases as either operating or capital leases for financial reporting purposes. Operating lease commitments consist principally of leases for the Company’s retail store facilities, distribution center, corporate office, IT systems hardware and distribution center delivery tractors. Capital lease obligations consist principally of leases for some of the Company’s IT systems hardware. 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. These contingent rents are expensed as they accrue. Deferred rent represents the difference between rent paid and the amounts expensed for operating leases. Certain leases have scheduled rent increases, and certain leases include an initial period of free or reduced rent as an inducement to enter into the lease agreement (“rent holidays”). The Company recognizes rent expense for rent increases and rent holidays on a straight-line basis over the term of the underlying leases, without regard to when rent payments are made. The calculation of straight-line rent begins on the possession date and extends through the “reasonably assured” lease term as defined in ASC 840 and may exceed the initial non-cancelable lease term. Landlord allowances for tenant improvements, or lease incentives, are recorded as deferred rent and amortized on a straight-line basis over the “reasonably assured” lease term as a component of rent expense. The Company evaluates its leases relative to asset retirement obligations, and determined these amounts to be immaterial.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	(3) Fair Value Measurements The carrying values of cash, accounts receivable, accounts payable and accrued expenses approximate the fair values of these instruments due to their short-term nature. The carrying amount for borrowings under the revolving 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’ assets are reduced to their estimated fair values. After the impairment charges, the carrying values of the remaining assets of these stores were not material.

Debt Disclosure [Abstract]
Long-Term Debt	(5) Long-Term Debt On October 18, 2010, the Company, Big 5 Corp. and Big 5 Services Corp. entered into a credit agreement with Wells Fargo Bank, National Association (“Wells Fargo”), as administrative agent, and a syndicate of other lenders, which was amended on October 31, 2011 and December 19, 2013 (as so amended, the “Credit Agreement”). On September 29, 2017, the parties amended certain provisions of the Credit Agreement (such amendment, the “Third Amendment”), as further discussed below. The amendment represented a modification and resulted in the payment and capitalization of $0.2 million in deferred financing fees. The Credit Agreement provides for a revolving credit facility (the “Credit Facility”) with an aggregate committed availability of up to $140.0 million, which amount may be increased at the Company’s option up to a maximum of $165.0 million. The Company may also request additional increases in aggregate availability, up to a maximum of $200.0 million, in which case the existing lenders under the Credit Agreement will have the option to increase their commitments to accommodate the requested increase. If such existing lenders do not exercise that option, the Company may (with the consent of Wells Fargo, not to be unreasonably withheld) seek other lenders willing to provide such commitments. T he Third Amendment includes a provision which permits the Company to elect to reduce the aggregate committed availability under the Credit Agreement to $100.0 million for a three-month period each calendar year. Prior to the Third Amendment, t The Company may borrow under the Credit Facility from time to time, provided the amounts outstanding will not exceed the lesser of the then aggregate availability (as discussed above) and the Borrowing Base (such lesser amount being referred to as the “Loan Cap”). 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 lesser of (i) 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), or (ii) $10.0 million, minus (d) certain reserves established by Wells Fargo in its role as the Administrative Agent in its reasonable discretion. Generally, the Company may designate specific borrowings under the Credit Facility as either base rate loans or LIBO 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 Loan Cap over amounts borrowed (such amount being referred to as the “Average Daily Availability”).

Obligations under the Credit Facility are secured by a general lien and perfected security interest in substantially all of the Company’s assets. The Credit 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 limit 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 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. The Credit 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 for five days after becoming due, failure to comply with certain agreements or covenants contained in the Credit Agreement, failure to satisfy certain judgments against the Company, failure to pay when due (or any other default which does or may lead to the acceleration of) certain other material indebtedness in principal amount in excess of $5.0 million, and certain insolvency and bankruptcy events. The Third Amendment extended the maturity date of the Credit Agreement from December 19, 2018 to September 29, 2022. As of July 1, 2018, the Company had long-term revolving credit borrowings of $90.7 million and letter of credit commitments of $0.4 million outstanding, compared with borrowings of $45.0 million and letter of credit commitments of $0.5 million as of December 31, 2017. Total remaining borrowing availability, after subtracting letters of credit, was $48.9 million and $94.5 million as of July 1, 2018 and December 31, 2017, respectively.

Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies	(8) Commitments and Contingencies In February 2008, the Company entered into a lease for a parcel of land with an existing building adjacent to its corporate headquarters location, including a parking lot currently used by the Company (the “premises”). The lease term commenced in 2009 and the primary term was originally scheduled to expire on February 28, 2019, subject to renewal for six successive periods of five years each. In accordance with terms of the lease agreement, the Company is committed to the construction of a new retail building on the premises before the primary term expires, regardless of whether or not any renewal options are exercised. In May 2017, the Company entered into an amendment to the lease to, among other things, extend the primary lease term, and consequently the construction deadline, to a date between February 29, 2020 and June 30, 2020. Such extension required a non-refundable payment of $40,000, which the Company made concurrently with execution of the amendment. In November 2017, the Company entered into an additional amendment to the lease concurrently with entering into a purchase and sale agreement. Pursuant to the purchase and sale agreement, the Company has the right to purchase the premises for $4.5 million. The purchase and sale agreement’s due diligence period expired on March 2, 2018, and in connection therewith, the Company paid an escrow deposit of $300,000 to be applied towards the purchase price of the property. The closing of the sale is scheduled to occur on or before November 27, 2018, subject to seller’s right to elect an earlier closing date. Pursuant to the amended lease, if consummation of the sale fails to occur by November 27, 2018, then the Company’s lease would remain in full force and effect, including the construction deadline, which would be the later of (a) February 29, 2020, or (b) the earlier of (i) two (2) years after the date that the purchase and sale agreement is terminated, or (ii) November 27, 2020. The Company is involved in various 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 adverse effect on the Company’s results of operations or financial condition.

Share-based Compensation	(9) Share-based Compensation 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 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. In the first half of fiscal 2018, the Company granted 254,900 share option awards with a weighted-average grant-date fair value of $1.23 per option. No share option awards were granted in the first half of fiscal 2017. A summary of the status of the Company’s share option awards is presented below: Shares Weighted- Average Exercise Price Weighted- Average Remaining Contractual Life (In Years) Aggregate Intrinsic Value Outstanding at December 31, 2017 144,293 $ 10.11 Granted 254,900 6.22 Exercised (6,564 ) 4.82 Forfeited or Expired (23,319 ) 8.95 Outstanding at July 1, 2018 369,310 $ 7.60 7.66 $ 492,570 Exercisable at July 1, 2018 108,993 $ 10.32 3.04 $ 143,751 Vested and Expected to Vest at July 1, 2018 360,672 $ 7.63 7.61 $ 480,840 The aggregate intrinsic value in the preceding table represents the total pretax intrinsic value, based upon the Company’s most recent closing stock price of $7.60 as of July 1, 2018, which would have been received by the option holders had all option holders exercised their option awards as of that date. The total intrinsic value of share option awards exercised for the 26 weeks ended July 1, 2018 and July 2, 2017 was approximately $10,000 and $34,000, respectively. The total cash received from employees as a result of employee share option award exercises for the 26 weeks ended July 1, 2018 and July 2, 2017 was approximately $31,000 and $28,000, respectively. The actual tax benefit realized for the tax deduction from share option award exercises of share-based compensation awards in the 26 weeks ended July 1, 2018 and July 2, 2017 totaled $3,000 and $13,000, respectively. The fair value of each share option award on the date of grant is estimated using the Black-Scholes method based on the following weighted-average assumptions: 13 Weeks Ended 26 Weeks Ended July 1, 2018 July 2, 2017 July 1, 2018 July 2, 2017 Risk-free interest rate 2.9 % — 2.6 % — Expected term 5.1 years — 5.1 years — Expected volatility 48.0 % — 48.0 % — Expected dividend yield 7.5 % — 9.5 % — The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant for periods corresponding with the expected term of the option award; the expected term represents the weighted-average period of time that option awards granted are expected to be outstanding giving consideration to vesting schedules and historical participant exercise behavior; the expected volatility is based upon historical volatility of the Company’s common stock; and the expected dividend yield is based upon the Company’s current dividend rate. As of July 1, 2018, there was $0.3 million of total unrecognized compensation expense related to nonvested share option awards granted. That expense is expected to be recognized over a weighted-average period of 3.6 years. Nonvested Share Awards and Nonvested Share Unit Awards Nonvested share awards and nonvested share unit 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, vest 100% on the first anniversary of the grant date. Nonvested share awards are delivered to the recipient upon their vesting. With respect to nonvested share unit awards, vested shares will be 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. The total fair value of nonvested share awards which vested during the first half of fiscal 2018 and 2017 was $1.0 million and $2.0 million, respectively. The total fair value of nonvested share unit awards which vested during the first half of fiscal 2018 and 2017 was $0.3 million and $0.3 million, respectively. The Company granted 213,062 and 191,000 nonvested share awards in the first half of fiscal 2018 and 2017, respectively. The weighted-average grant-date fair value per share of the Company’s nonvested share awards granted in the first half of fiscal 2018 and 2017 was $6.99 and $14.88, respectively. A summary of the status of the Company’s nonvested share awards is presented below: Shares Weighted- Average Grant- Date Fair Value Balance at December 31, 2017 377,035 $ 13.61 Granted 213,062 6.99 Vested (144,205 ) 13.66 Forfeited (4,570 ) 12.10 Balance at July 1, 2018 441,322 $ 10.42 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 half of fiscal 2018, the Company withheld 53,343 common shares with a total value of $0.4 million. This amount is presented as a cash outflow from financing activities in the accompanying interim unaudited condensed consolidated statement of cash flows. The Company granted 34,884 and 21,000 nonvested share unit awards in the first half of fiscal 2018 and 2017, respectively. The weighted-average grant-date fair value of the Company’s nonvested share unit awards granted in the first half of fiscal 2018 and 2017 was $8.60 and $13.90, respectively.

Use of Estimates	Use of Estimates Management has made a number of estimates and assumptions relating to the reporting of assets, liabilities and stockholders’ equity and the disclosure of contingent assets and liabilities as of 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, and property and equipment; valuation allowances for receivables, sales returns and deferred income tax assets; estimates related to gift cards and returned merchandise credits (collectively, “stored-value cards”) and the valuation of share-based compensation awards; and obligations related to litigation, self-insurance liabilities and employee benefits. Actual results could differ significantly from these estimates under different assumptions and conditions.
Revenue Recognition	Revenue Recognition On January 1, 2018, the Company adopted Accounting Standards Codification (“ASC”) 606, Revenue from Contracts with Customers, 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 revenues are recognized when control of the promised goods is transferred to customers, in 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. Collectibility is reasonably assured since the Company only extends immaterial credit purchases to certain municipalities and local school districts. As noted in the segment information in the notes to the consolidated financial statements of the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2017 and Note 1 to these Interim Financial Statements, the Company’s business consists of one reportable segment. In accordance with ASC 606, 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 26 Weeks Ended July 1, 2018 July 2, 2017 July 1, 2018 July 2, 2017 (In thousands) Hard goods $ 129,013 $ 132,958 $ 233,464 $ 243,712 Athletic and sport apparel 42,590 41,949 101,036 107,078 Athletic and sport footwear 67,199 67,803 136,552 141,971 Other sales 1,149 961 3,077 3,514 Net sales $ 239,951 $ 243,671 $ 474,129 $ 496,275 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 at a point in time upon redemption of the stored-value card through consummation of a future sales transaction. The transaction price for each contract is the stated price on the product, reduced by any stated discounts at that point in time. The Company does not engage in sales of products that attach a future material right which could result in a separate performance obligation for the purchase of goods in the future at a material discount. The implicit point-of-sale contract with the customer, as reflected in the transaction receipt, states the final terms of the sale, including the description, quantity, and price of each product purchased. Payment for the Company’s contracts is due in full upon delivery. The customer agrees to a stated price implicit in the contract. The transaction price relative to sales subject to a right of return reflects the amount of estimated consideration to which the Company expects to be entitled. This amount of variable consideration included in the transaction price, and measurement of net sales, is included in net sales only to the extent that it is probable that there will be no significant reversal in a future period. Actual amounts of consideration ultimately received may differ from the Company’s estimates. The allowance for sales returns is estimated based upon historical experience and a provision for estimated returns is recorded as a reduction in sales in the relevant period. The estimated right-of-return merchandise cost related to the sales returns is recorded as prepaid expense in the Company’s interim unaudited condensed consolidated balance sheet as of July 1, 2018. If actual results in the future vary from the Company’s estimates, the Company adjusts these estimates, which would affect net sales and earnings in the period such variances become known. The Company has elected to apply the practical expedient, relative to e-commerce sales, which allows an entity to account for shipping and handling 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 is not material. Contract liabilities are recognized primarily for stored-value card sales. Cash received from the sale of stored-value cards is recorded as a contract liability in accrued expenses, and the Company recognizes revenue upon the customer’s redemption of the stored-value card. Stored-value card breakage is recognized as revenue in proportion to the pattern of customer redemptions by applying a historical breakage rate of five percent. The Company does not sell or provide stored-value cards that carry expiration dates. The Company recognized approximately $1.7 million and $3.9 million in stored-value card redemption revenue for the 13 and 26 weeks ended July 1, 2018, respectively, and for the 13 and 26 weeks ended July 2, 2017, respectively. The Company also recognized approximately $88,000 and $206,000 in stored-value card breakage revenue for the 13 and 26 weeks ended July 1, 2018, respectively, compared to approximately $111,000 and $223,000 in stored-value card breakage revenue for the 13 and 26 weeks ended July 2, 2017, respectively. The Company had outstanding stored-value card liabilities of $5.7 million and $7.4 million The Company recorded, as prepaid expense, estimated right-of-return merchandise cost of $0.9 million related to estimated sales returns and an allowance for sales returns reserve of $1.8 million as of July 1, 2018 under ASC 606, which would have been reported as a net liability of $0.9 million with no estimated right-of-return merchandise cost recorded as of July 1, 2018 under ASC 605.
Share-Based Compensation	Share-Based Compensation The Company accounts for share-based compensation in accordance with ASC 718, Compensation—Stock Compensation
Valuation of Merchandise Inventories, Net	Valuation of Merchandise Inventories, Net The Company’s merchandise inventories are made up of finished goods and are valued at the lower of cost or net realizable value using the weighted-average cost method, which approximates the first-in, first-out (“FIFO”) method. Average cost includes the direct purchase price of merchandise inventory, net of certain 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 The Company reviews long-lived assets for recoverability whenever events or changes in circumstances indicate that the carrying amount of an asset may be impaired. 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. Each store typically requires net investments of approximately $0.5 million in long-lived assets to be held and used, subject to recoverability testing. The carrying amount of an 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 asset group. If the 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 asset group exceeds its fair value, determined using discounted cash flow valuation techniques, as defined in ASC 360, Property, Plant, and Equipment The Company determines the sum of the undiscounted cash flows expected to result from the asset group by projecting future revenue, gross margin and operating expense for each store 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 future expectations, competitive factors in the various markets and inflation. The actual cash flows could differ from management’s estimates due to changes in business conditions, operating performance and economic conditions. The Company recognized no impairment charges in the first half of fiscal 2018 or 2017.
Leases and Deferred Rent	Leases and Deferred Rent The Company accounts for its leases under the provisions of ASC 840, Leases The Company evaluates and classifies its leases as either operating or capital leases for financial reporting purposes. Operating lease commitments consist principally of leases for the Company’s retail store facilities, distribution center, corporate office, IT systems hardware and distribution center delivery tractors. Capital lease obligations consist principally of leases for some of the Company’s IT systems hardware. 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. These contingent rents are expensed as they accrue. Deferred rent represents the difference between rent paid and the amounts expensed for operating leases. Certain leases have scheduled rent increases, and certain leases include an initial period of free or reduced rent as an inducement to enter into the lease agreement (“rent holidays”). The Company recognizes rent expense for rent increases and rent holidays on a straight-line basis over the term of the underlying leases, without regard to when rent payments are made. The calculation of straight-line rent begins on the possession date and extends through the “reasonably assured” lease term as defined in ASC 840 and may exceed the initial non-cancelable lease term. Landlord allowances for tenant improvements, or lease incentives, are recorded as deferred rent and amortized on a straight-line basis over the “reasonably assured” lease term as a component of rent expense. The Company evaluates its leases relative to asset retirement obligations, and determined these amounts to be immaterial.
