Basis of Presentation and Summary of Significant Accounting Policies | 1. Basis of Presentation and Summary of Significant Accounting Policies Nature of Business The Company is organized under the laws of the State of California. Effective October 18, 2013, 99¢ Only Stores converted from a California corporation to a California limited liability company, 99 Cents Only Stores LLC, that is managed by its sole member, Number Holdings, Inc., a Delaware corporation (“Parent”). The term “Company” refers to 99¢ Only Stores and its consolidated subsidiaries prior to the Conversion (as described in Note 1 to the Annual Report on Form 10-K for the fiscal year ended January 27, 2017) and to 99 Cents Only Stores LLC and its consolidated subsidiaries at the time of or after the Conversion. The Company is an extreme value retailer of consumable and general merchandise and seasonal products. As of July 28, 2017, the Company operated 390 retail stores with 283 in California, 48 in Texas, 38 in Arizona, and 21 in Nevada. The Company is also a wholesale distributor of various products. Merger On January 13, 2012, the Company was acquired through a merger (the “Merger”) with a subsidiary of Parent with the Company surviving. In connection with the Merger, the Company became a subsidiary of Parent, which is controlled by affiliates of Ares Management, L.P. (“Ares”) and Canada Pension Plan Investment Board (“CPPIB” and, together with Ares, the “Sponsors”). As a result of the Merger, the Company’s common stock was delisted from the New York Stock Exchange and the Company ceased to be a publicly held and traded equity company. Basis of Presentation The accompanying unaudited consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States (“GAAP”). However, certain information and footnote disclosures normally included in financial statements prepared in conformity with GAAP have been omitted or condensed pursuant to the rules and regulations of the Securities and Exchange Commission. These statements should be read in conjunction with the Company’s audited financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended January 27, 2017. In the opinion of the Company’s management, these interim unaudited consolidated financial statements reflect all adjustments (consisting of normal recurring adjustments) necessary for a fair statement of the consolidated financial position and results of operations for each of the periods presented. The results of operations and cash flows for such periods are not necessarily indicative of results to be expected for the full fiscal year ending February 2, 2018 (“fiscal 2018”). Fiscal Year The Company follows a fiscal calendar consisting of four quarters with 91 days, each ending on the Friday closest to the last day of April, July, October or January, as applicable, and a 52-week fiscal year with 364 days, with a 53-week year every five to six years. Unless otherwise stated, references to years in this Report relate to fiscal years rather than calendar years. The Company’s fiscal 2018 began on January 28, 2017, will end on February 2, 2018 and will consist of 53 weeks. The Company’s fiscal year 2017 (“fiscal 2017”) began on January 30, 2016, ended on January 27, 2017 and consisted of 52 weeks. The second quarter ended July 28, 2017 (the “second quarter of fiscal 2018”) and the second quarter ended July 29, 2016 (the “second quarter of fiscal 2017”) were each comprised of 91 days. Each of the six-month period ended July 28, 2017 (the “first half of fiscal 2018”) and the six-month period ended July 29, 2016 (the “first half of fiscal 2017”) was comprised of 182 days. Use of Estimates The preparation of the unaudited consolidated financial statements, in conformity with GAAP, requires management to make estimates and assumptions. These estimates and assumptions affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the unaudited consolidated financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Cash For purposes of reporting cash flows, cash includes cash on hand, cash at the stores and cash in financial institutions. The majority of payments due from financial institutions for the settlement of debit card and credit card transactions are processed within three business days and therefore are also classified as cash. Cash balances held at financial institutions are generally in excess of federally insured limits. These accounts are only insured by the Federal Deposit Insurance Corporation up to $250,000. The Company historically has not experienced any losses in such accounts. The Company places its temporary cash investments with what it believes to be high credit, quality financial institutions. Under the Company’s cash management system, checks issued but not presented to the bank may result in book cash overdraft balances for accounting purposes. The Company reclassifies book overdrafts to accounts payable, which are reflected as an operating activity in its unaudited consolidated statements of cash flows. Book overdrafts included in accounts payable were $7.9 million and $7.0 million as of July 28, 2017 and January 27, 2017, respectively. Allowance for Doubtful Accounts In connection with its wholesale business, the Company evaluates the collectability of accounts receivable based on a combination of factors. In cases where the Company is aware of circumstances that may impair a specific customer’s or tenant’s ability to meet its financial obligations subsequent to the original sale, the Company will record an allowance against amounts due and thereby reduce the net recognized receivable to the amount the Company reasonably believes will be collected. For all other customers and tenants, the Company recognizes allowances for doubtful accounts based on the length of time the receivables are past due, industry and geographic concentrations, the current business environment and the Company’s historical experiences. Inventories Inventories are valued at the lower of cost or net realizable value. Inventory costs are established using a methodology that approximates first in, first out, which for store inventories is based on a retail inventory method. Valuation allowances for shrinkage as well as excess and obsolete inventory are also recorded. The Company includes spoilage, scrap and shrink in its definition of shrinkage. Shrinkage is estimated as a percentage of sales for the period from the last physical inventory date to the end of the applicable period. Such estimates are based on experience and the most recent physical inventory results. Physical inventory counts are completed at each of the Company’s retail stores at least once a year by an outside inventory service company. The Company performs inventory cycle counts at its warehouses throughout the year. The Company also performs inventory reviews and analysis on a quarterly basis for both warehouse and store inventory to determine inventory valuation allowances for excess and obsolete inventory. The valuation allowances for excess and obsolete inventory are based on the age of the inventory, sales trends and future merchandising plans. The valuation allowances for excess and obsolete inventory require management judgment and estimates that may impact the ending inventory valuation and valuation allowances that may have a material effect on the reported gross margin for the period. These estimates are subject to change based on management’s evaluation of, and response to, a variety of factors and trends, including, but not limited to, consumer preferences and buying patterns, age of inventory, increased competition, inventory management, merchandising strategies and historical sell through trends. The Company’s ability to adequately evaluate the impact of inventory management and merchandising strategies executed in response to such factors and trends in future periods could have a material impact on such estimates. In order to obtain inventory at attractive prices, the Company takes advantage of large volume purchases, closeouts and other similar purchase opportunities. Consequently, the Company’s inventory fluctuates from period to period and the inventory balances vary based on the timing and availability of such opportunities. Property and Equipment Property and equipment are carried at cost and are depreciated or amortized on a straight-line basis over the following useful lives: Owned buildings and improvements Lesser of 30 years or the estimated useful life of the improvement Leasehold improvements Lesser of the estimated useful life of the improvement or remaining lease term Fixtures and equipment 3-5 years Transportation equipment 3-5 years Information technology systems For major corporate systems, estimated useful life up to 7 years; for functional standalone systems, estimated useful life up to 5 years The Company’s policy is to capitalize expenditures that materially increase asset lives and expense ordinary repairs and maintenance as incurred. Long-Lived Assets The Company assesses the impairment of depreciable long-lived assets when events or changes in circumstances indicate that the carrying value may not be recoverable. The Company groups and evaluates long-lived assets for impairment at the individual store level, which is the lowest level at which individual identifiable cash flows are available. Recoverability is measured by comparing the carrying amount of an asset to expected future net cash flows generated by the asset. If the carrying amount of an asset exceeds its estimated undiscounted future cash flows, the carrying amount is compared to its fair value and an impairment charge is recognized to the extent of the difference. Factors that the Company considers important that could individually or in combination trigger an impairment review include the following: (1) significant underperformance relative to expected historical or projected future operating results; (2) significant changes in the manner of the Company’s use of the acquired assets or the strategy for the Company’s overall business; and (3) significant changes in the Company’s business strategies and/or negative industry or economic trends. On a quarterly basis, the Company assesses whether events or changes in circumstances occur that potentially indicate that the carrying value of long-lived assets may not be recoverable (Level 3 measurement, see Note 7, “Fair Value of Financial Instruments”). Considerable management judgment is necessary to estimate projected future operating cash flows. Accordingly, if actual results fall short of such estimates, significant future impairments could result. During the second quarter of fiscal 2018, the Company decided to close three stores by the end of fiscal 2018 or early fiscal 2019. Of these three stores, one will close upon lease expiration and two will close through exercise by the Company of its early lease termination rights. As a result of this decision, the Company recognized an impairment charge of approximately $1.5 million as part of selling, general and administrative expenses in the second quarter of fiscal 2018 related to the planned closure of these stores. During the first half of fiscal 2017, the Company did not record any long-lived asset impairment charges. Goodwill and Other Intangible Assets In connection with the Merger purchase price allocation, the fair values of long-lived and intangible assets were determined based upon assumptions related to the future cash flows, discount rates and asset lives using then available information, and in some cases were obtained from independent professional valuation experts. The Company amortizes intangible assets over their estimated useful lives unless such lives are deemed indefinite. Amortizable intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset or asset group may not be recoverable based on undiscounted cash flows, and, if impaired, written down to fair value based on either discounted cash flows or appraised values. Significant judgment is required in determining whether a potential indicator of impairment of long-lived assets exists and in estimating future cash flows used in the impairment tests (Level 3 measurement, see Note 7, “Fair Value of Financial Instruments”). Goodwill and indefinite-lived intangible assets are not amortized but instead tested annually for impairment or more frequently when events or changes in circumstances indicate that the assets might be impaired. Goodwill is tested for impairment by comparing the carrying amount of the reporting unit to the fair value of the reporting unit to which the goodwill is assigned. The Company has the option of performing a qualitative assessment before calculating the fair value of the reporting unit (i.e., step zero of the goodwill impairment test). If the Company does not perform a qualitative assessment, or determines, on the basis of qualitative factors, that the fair value of the reporting unit is more likely than not less than the carrying amount, the two-step impairment test would be required. The first step is to compare the fair value of the reporting unit with its carrying amount, including goodwill. If the fair value of the reporting unit exceeds its carrying amount, goodwill is considered not impaired; otherwise, goodwill is impaired and the loss is measured by performing step two. Under step two, the impairment loss is measured by comparing the implied fair value of the reporting unit’s goodwill with the carrying amount of goodwill. Management has determined that the Company has two reporting units, the retail reporting unit and the wholesale reporting unit. The Company, assisted by an independent third party valuation firm, performs the annual test for impairment in January of the fiscal year and determines fair value based on a combination of the income approach and the market approach. The income approach is based on discounted cash flows to determine fair value. The market approach uses a selection of comparable companies and transactions in determining fair value. The fair value of the trade name is also tested for impairment in the fourth quarter by comparing the carrying value to the fair value. Fair value of a trade name is determined using a relief from royalty method under the income approach, which uses projected revenue allocable to the trade name and an assumed royalty rate (Level 3 measurement, see Note 7, “Fair Value of Financial Instruments”). These approaches involve making key assumptions about future cash flows, discount rates and asset lives using then best available information. These assumptions are subject to a high degree of complexity and judgment and are subject to change. During the third quarter of fiscal 2016, the Company determined that indicators of impairment existed to require an interim impairment analysis of goodwill and trade name. The first step evaluation concluded that the fair value of the retail reporting unit was below its carrying value. The Company performed step two of the goodwill impairment test. As a result of the preliminary analysis and based on best estimate, the Company recorded a $120.0 million non-cash goodwill impairment charge in the third quarter of fiscal 2016, which was reflected as goodwill impairment in the consolidated statements of comprehensive income (loss). The finalization of the preliminary goodwill impairment test was completed in the fourth quarter of fiscal 2016 and resulted in a $20.9 million adjustment in goodwill, lowering the estimated third quarter of fiscal 2016 goodwill impairment charge from $120.0 million to $99.1 million. The remaining amount of goodwill allocated to the retail reporting unit and wholesale reporting unit was $368.1 million and $12.5 million, respectively, as of January 29, 2016. During the fourth quarter of fiscal 2017, the Company completed step one of its annual goodwill impairment test for the two reporting units and determined that there was no impairment of goodwill since the fair value of the Company’s reporting units exceeded their carrying amounts. The results of this test showed that the fair value of our retail reporting unit exceeded its carrying value by a substantial amount. The results of this test showed that the fair value of wholesale reporting unit exceeded carrying value by approximately 18%. As discussed above, considerable management judgment is necessary in estimating future cash flows, market interest rates, discount rates and other factors affecting the valuation of goodwill. The Company’s forecasts used in its fiscal 2017 annual impairment test include growth in net sales, new store openings and same-store sales, positive trends in cost of sales and selling, general and administrative expense. In each case, these estimates and assumptions could be materially affected by factors such as unforeseen events or changes in general economic conditions, a decline in comparable company market multiples, changes to discount rates, increased competitive forces, inability to maintain pricing structure, deterioration of vendor relationships, failure to adequately manage and improve inventory processes and procedures and changes in customer behavior which could result in changes to management’s strategies. If operating results continue to change versus the Company’s expectations, additional impairment charges may be recorded in the future. Additionally, during the fourth quarter of fiscal 2017, the Company completed its annual indefinite-lived intangible asset impairment test and determined there was no impairment to the trade name since the fair value of the trade name exceeded its carrying amount. The results of this test showed that the fair value of trade name exceeded carrying value by approximately 18%. The relief from royalty method estimates our theoretical royalty savings from ownership of the intangible asset. Key assumptions used in this model included sales projections, discount rates and royalty rates, and considerable management judgment is necessary in developing and evaluating such assumptions. If future results are not consistent with current estimates and assumptions, impairment charges maybe recorded in future. During the first half of fiscal 2018, the Company did not record any impairment charges related to goodwill or other intangible assets. Derivatives The Company accounts for derivative financial instruments in accordance with authoritative guidance for derivative instrument and hedging activities. Financial instrument positions taken by the Company are primarily intended to be used to manage risks associated with interest rate exposures. The Company’s derivative financial instruments are recorded on the balance sheet at fair value, and are recorded in either current or noncurrent assets or liabilities based on their maturity. Changes in the fair values of derivatives are recorded in net earnings or other comprehensive income (“OCI”), based on whether the instrument is designated and effective as a hedge transaction and, if so, the type of hedge transaction. Gains or losses on derivative instruments reported in accumulated other comprehensive income (“AOCI”) are reclassified to earnings in the period the hedged item affects earnings. Any ineffectiveness is recognized in earnings in the period incurred. Income Taxes The Company uses the liability method of accounting for income taxes. Under the liability method, deferred tax assets and liabilities are recognized using enacted tax rates for the effect of temporary differences between the book and tax bases of recorded assets and liabilities. Deferred tax assets are reduced by a valuation allowance if it is more likely than not that some portion or all of the deferred tax assets will not be realized. The Company’s ability to realize deferred tax assets is assessed throughout the year and a valuation allowance is established accordingly. The Company recognizes the impact of a tax position only if it is more likely than not to be sustained upon examination based on the technical merits of the position. The Company recognizes potential interest and penalties related to uncertain tax positions in income tax expense. Refer to Note 10, “Income Taxes,” for further discussion of income taxes. Stock-Based Compensation The Company accounts for stock-based payment awards based on their fair value. The value of the portion of the award that is ultimately expected to vest is recognized as an expense ratably over the requisite service periods. For awards classified as equity, the Company estimates the fair value for each option award as of the date of grant using the Black-Scholes option pricing model or other appropriate valuation models. The Black-Scholes model considers, among other factors, the expected life of the award and the expected volatility of the stock price. Stock options are generally granted to employees at exercise prices equal to or greater than the fair market value of the stock at the dates of grant. The fair value of options that vest based on the Company’s and Parent’s achievement of certain performance hurdles were valued using a Monte Carlo simulation method. The fair value of options granted to the current Chief Executive Officer were valued using a binomial model and the Monte Carlo simulation method. Refer to Note 8, “Stock-Based Compensation” for further discussion of the Company’s stock-based compensation. Revenue Recognition The Company recognizes retail sales in its retail stores at the time the customer takes possession of merchandise. All sales are net of discounts and returns and exclude sales tax. Wholesale sales are recognized in accordance with the shipping terms agreed upon on the purchase order. Wholesale sales are typically recognized free on board origin, where title and risk of loss pass to the buyer when the merchandise leaves the Company’s distribution facility. The Company has a gift card program. The Company does not charge administrative fees on gift cards and the Company’s gift cards do not have expiration dates. The Company records the sale of gift cards as a current liability and recognizes a sale when a customer redeems a gift card. The liability for outstanding gift cards is recorded in accrued expenses. Cost of Sales Cost of sales includes the cost of inventory, freight in, obsolescence, spoilage, scrap and inventory shrink, and is net of discounts and allowances. Cost of sales also includes receiving, warehouse costs and distribution costs (which include payroll and associated costs, occupancy, transportation to and from stores and depreciation expense). Cash discounts for satisfying early payment terms are recognized when payment is made, and allowances and rebates based upon milestone achievements such as reaching a certain volume of purchases of a vendor’s products are included as a reduction of cost of sales when such contractual milestones are reached or based on other systematic and rational approaches where possible. Selling, General and Administrative Expenses Selling, general and administrative expenses include the costs of selling merchandise in stores (which include payroll and associated costs, occupancy and other store-level costs) and corporate costs (which include payroll and associated costs, occupancy, advertising, professional fees and other corporate administrative costs). Selling, general and administrative expenses also include depreciation and amortization expense relating to these costs. Leases The Company follows the policy of capitalizing allowable expenditures that relate to the acquisition and signing of its retail store leases. These costs are amortized on a straight-line basis over the applicable lease term. The Company recognizes rent expense for operating leases on a straight-line basis (including the effect of reduced or free rent and rent escalations) over the applicable lease term. The difference between the cash paid to the landlord and the amount recognized as rent expense on a straight-line basis is included in deferred rent. Cash reimbursements received from landlords for leasehold improvements and other cash payments received from landlords as lease incentives are recorded as deferred rent. Deferred rent related to landlord incentives is amortized as an offset to rent expense using the straight-line method over the applicable lease term. In certain lease arrangements, the Company can be involved with the construction of the building. If it is determined that the Company has substantially all of the risks of ownership during construction of the leased property and therefore is deemed to be the owner of the construction project, the Company records an asset for the amount of the total project costs and an amount related to the value attributed to the pre-existing leased building in property and equipment, net and the related financing obligation as part of current and non-current liabilities. Once construction is complete, if it is determined that the asset does not qualify for sale-leaseback accounting treatment, the Company amortizes the obligation over the lease term and depreciates the asset over the life of the lease. The Company does not report rent expense for the portion of the rent payment determined to be related to the assets which are owned for accounting purposes. Rather, this portion of the rent payment under the lease is recognized as a reduction of the financing obligation and interest expense. For store closures where a lease obligation still exists, the Company records the estimated future liability associated with the rental obligation on the cease use date (when the store is closed). Liabilities are established at the cease use date for the present value of any remaining operating lease obligations, net of estimated sublease income, and at the communication date for severance and other exit costs. Key assumptions in calculating the liability include the timeframe expected to terminate lease agreements, estimates related to the sublease potential of closed locations, and estimates of other related exit costs. If actual timing and potential termination costs or realization of sublease income differ from the Company’s estimates, the resulting liabilities could vary from recorded amounts. These liabilities are reviewed periodically and adjusted when necessary. During the first quarter of fiscal 2018, the Company sold and concurrently leased back a future store site with an aggregate carrying value of $1.4 million and received net proceeds from this transaction of $6.8 million, which will be applied towards the construction of the future store. The Company was deemed to have “continuing involvement,” which precluded the de-recognition of the assets from the consolidated balance sheet when the transaction closed. The Company has concluded that it is the “deemed owner” of the construction project (for accounting purposes) during the construction period. Upon completion of construction, the Company will evaluate the de-recognition of the asset and liability under sale-leaseback accounting guidance. As of July 28, 2017, the Company has recorded a financing lease obligation of $7.0 million (as a component of current and non-current liabilities). During the first quarter of fiscal 2018, the Company sold and concurrently leased back a store with a carrying value of $2.2 million and received net proceeds from this transaction of $4.0 million. The resulting lease qualifies as and is accounted for as an operating lease. The Company will amortize the deferred gain of $1.8 million relating to the sale-leaseback transaction over the lease term. During the second quarter of fiscal 2018, the Company sold and concurrently leased back a store with a carrying value of $3.7 million and received net proceeds from this transaction of $7.9 million. The Company was deemed to have “continuing involvement,” which precluded the de-recognition of the assets from the consolidated balance sheet when the transaction closed. The resulting lease is accounted for as a financing lease and the Company has recorded a financing lease obligation of $7.9 million (as a component of current and non-current liabilities). Also during the second quarter of fiscal 2018, the Company sold and concurrently leased back a store with a carrying value of $1.1 million and received net proceeds from this transaction of $5.3 million. The resulting lease qualifies as and is accounted for as an operating lease. The Company recorded a gain on the sale of $1.7 million as part of selling, general and administrative expenses and will amortize the deferred gain of $2.5 million relating to the sale-leaseback transaction over the lease term. During the second quarter of fiscal 2016, the Company sold and concurrently leased back two retail stores with a carrying value of $7.9 million and received net proceeds from these transactions of $8.7 million. The Company was deemed to have “continuing involvement,” which precluded the de-recognition of the assets from the consolidated balance sheet when the transactions closed. The resulting leases were accounted for as financing leases and the Company had recorded a corresponding financing lease obligation of $8.7 million (as a component of current and non-current liabilities). The Company amortized the financing lease obligation over the lease terms and depreciated the assets over their remaining useful lives. During the second quarter of fiscal 2018, the Company was no longer deemed to have “continuing involvement” and the leases now qualify and are accounted for as operating leases. The-Company de-recognized the assets and financing lease obligation and recorded a net loss of $0.8 million as part of selling, general and administrative expenses in the second quarter of fiscal 2018 and will amortize deferred gain of $2.1 million relating to the sale-leaseback transaction over the lease term. Self-Insured Workers’ Compensation Liability The Company self-insures for workers’ compensation claims in California and Texas. The Company establishes a liability for losses from both estimated known and incurred but not reported insurance claims based on reported claims and actuarial valuations of estimated future costs of known and incurred but not yet reported claims. Should an amount of claims greater than anticipated occur, the liability recorded may not be sufficient and additional workers’ compensation costs, which may be significant, could be incurred. The Company has not discounted the projected future cash outlays for the time value of money for claims and claim-related costs when establishing its workers’ compensation liability in its financial reports for each of July 28, 2017 and January 27, 2017. Self-Insured Health Insurance Liability The Company self-insures for a portion of its employee medical benefit claims. The liability for the self-funded portion of the Company health insurance program is determined actuarially, based on claims filed and an estimate of claims incurred but not yet reported. The Company maintains stop loss insurance coverage to limit its exposure for the self-funded portion of its health insurance program. Pre-Opening Costs The Company expenses, as incurred, pre-opening costs such as payroll, rent and marketing related to the opening of new retail stores. Advertising The Company expenses advertising costs as incurred. Fair Value of Financial Instruments The Company’s financial instruments consist principally of cash, accounts receivable, interest rate and other derivatives, accounts payable, accruals, debt, and other liabilities. Cash and derivatives are measured and recorded at fair value. Accounts receivable and other receivables are financial assets with carrying values that approximate fair value. Accounts payable and other accrued expenses are financial liabilities with carrying values that approximate fair value. Refer to Note 7, “Fair Value of Financial Instruments” for further discussion of the fair value of debt. The Company uses the authoritative guidance for fair value, which includes the definition of fair value, the framework for measuring fair value, and disclosures about fair value measurements. Fair value is an exit price, representing the amount that would be received from the sale of an asset or paid to transfer a liability in an orderly transaction between market participants. Fair value measurements reflect the assu |
