Business	Business. Ross Stores, Inc. and its subsidiaries (the “Company”) is an off-price retailer of first-quality, in-season, name brand and designer apparel, accessories, footwear, and home fashions for the entire family. At the end of fiscal 2022, the Company operated 1,693 Ross Dress for Less® (“Ross”) locations in 40 states, the District of Columbia, and Guam, and 322 dd’s DISCOUNTS® stores in 21 states. The Ross and dd’s DISCOUNTS stores are supported by the Company’s headquarters, buying offices, and its network of distribution centers/warehouses.
Basis of presentation	Basis of presentation and fiscal year. The consolidated financial statements include the accounts of the Company and its subsidiaries, all of which are wholly-owned. Intercompany transactions and accounts have been eliminated.
Fiscal year	The Company follows the National Retail Federation fiscal calendar and utilizes a 52-53 week fiscal year whereby the fiscal year ends on the Saturday nearest to January 31. The fiscal years ended January 28, 2023, January 29, 2022, and January 30, 2021 are referred to as fiscal 2022, fiscal 2021, and fiscal 2020, respectively, and were 52-week years.
Use of accounting estimates	Use of accounting estimates. The preparation of consolidated financial statements in conformity with Generally Accepted Accounting Principles in the United States of America (“GAAP”) requires the Company to make estimates and assumptions that affect the reported amounts of assets, liabilities, and disclosures of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. The Company’s significant accounting estimates include valuation reserves for inventory, packaway and other inventory carrying costs, useful lives of fixed assets, insurance reserves, reserves for uncertain tax positions, and legal claims. The uncertainties and potential impacts from macroeconomic factors, such as inflation, increase the challenge of making these estimates; actual results could differ materially from the Company’s estimates.
Segment reporting	Segment reporting. The Company has one reportable segment. The Company’s operations include only activities related to off-price retailing in stores throughout the United States.
Cash and cash equivalents	Cash and cash equivalents. Cash equivalents consist of highly liquid, fixed income instruments purchased with an original maturity of three months or less. The institutions where these instruments are held could potentially subject the Company to concentrations of credit risk. The Company manages its risk associated with these instruments by primarily holding its cash and cash equivalents across a highly diversified set of banks and other financial institutions.
Restricted cash, cash equivalents, and investments	Restricted cash, cash equivalents, and investments. Restricted cash, cash equivalents, and investments serve as collateral for certain insurance obligations and has also served as collateral for certain trade payable obligations of the Company. These restricted funds are invested in bank deposits, money market mutual funds, U.S. Government and agency securities, and corporate securities and cannot be withdrawn from the Company’s account without the prior written consent of the secured parties. The classification between current and long-term is based on the timing of expected payments of the obligations.
Estimated fair value of financial instruments	Estimated fair value of financial instruments. The carrying value of cash and cash equivalents, short- and long-term investments, restricted cash and cash equivalents, restricted investments, accounts receivable, other long-term assets, accounts payable, and other long-term liabilities approximates their estimated fair value. Refer to Note B: Fair Value Measurements and Note D: Debt for additional information. Cash and cash equivalents were $4.6 billion and $4.9 billion at January 28, 2023 and January 29, 2022, respectively, and include bank deposits and money market funds for which the fair value was determined using quoted prices for identical assets in active markets, which are considered to be Level 1 inputs under the fair value measurements and disclosures guidance.
Merchandise inventory	Merchandise inventory. Merchandise inventory is stated at the lower of cost (determined using a weighted-average basis) or net realizable value. The Company purchases inventory that can either be shipped to stores or processed as packaway merchandise with the intent that it will be warehoused and released to stores at a later date. The timing of the release of packaway inventory to the stores is principally driven by the product mix, seasonality of the merchandise, and its relation to the Company’s store merchandise assortment plans. As such, the aging of packaway varies by merchandise category and seasonality of purchase, but typically packaway remains in storage less than six months. Merchandise inventory includes acquisition, transportation, processing, and storage costs related to packaway inventory. The cost of the Company’s merchandise inventory is reduced by valuation reserves for shortage based on historical shortage experience from the Company’s physical merchandise inventory counts and cycle counts.
Cost of goods sold and Revenue recognition	Cost of goods sold. In addition to product costs, the Company includes in cost of goods sold its buying, distribution, and freight expenses, as well as occupancy costs and depreciation and amortization related to the Company’s retail stores, buying, and distribution facilities. Buying expenses include costs to procure merchandise inventories. Distribution expenses include the cost of operating the Company’s distribution centers, warehouses, and cross-dock facilities.Revenue recognition. The Company recognizes revenue at the point of sale, net of sales taxes collected and an allowance for estimated future returns, as required by Accounting Standards Update (“ASU”) No. 2014-09, Revenue from Contracts with Customers, or Accounting Standards Codification (“ASC”) 606. The Company recognizes allowances for estimated sales returns on a gross basis as a reduction to sales. The asset recorded for the expected recovery of merchandise inventory was $11.8 million, $10.5 million, and $10.7 million and the liability recorded for the refund due to the customer was $23.1 million, $20.3 million, and $21.2 million as of January 28, 2023, January 29, 2022, and January 30, 2021, respectively. Sales taxes collected that are outstanding and the allowance for estimated future returns are included in Accrued expenses and other and the asset for expected recovery of merchandise is included in Prepaid expenses and other in the Consolidated Balance Sheets.Sales of stored value cards are deferred until they are redeemed for the purchase of Company merchandise. The Company’s stored value cards do not have expiration dates. Based upon historical redemption rates, a small percentage of stored value cards will never be redeemed, which represents breakage. Breakage is estimated and recognized as revenue based upon the historical pattern of customer redemptions.
Property and equipment	Property and equipment. Property and equipment are stated at cost, less accumulated depreciation and amortization. Depreciation is calculated using the straight-line method over the estimated useful life of the asset, typically ranging from three years to 12 years for equipment, 20 years to 40 years for land improvements and buildings, and three years to seven years for computer software costs incurred in developing or obtaining software for internal use. The cost of leasehold improvements is amortized over the useful life of the asset or the applicable lease term, whichever is less. Depreciation and amortization expense on property and equipment was $394.7 million, $360.7 million, and $364.2 million for fiscal 2022, 2021, and 2020, respectively. The Company capitalizes interest during the construction period of facilities and during the development and implementation phase of software projects.
Impairment of long-lived assets	Impairment of long-lived assets. Property and other long-term assets that are subject to depreciation and amortization are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable based on estimated undiscounted future cash flows. For stores that are closed, the Company records an impairment charge, if appropriate, or accelerates depreciation over the revised useful life of the asset. Intangible assets that are not subject to amortization, including goodwill, are tested for impairment annually or more frequently if events or changes in circumstances indicate that the asset may be impaired.
Accounts payable	Accounts payable. Accounts payable represents amounts owed to third parties at the end of the period. Accounts payable includes book cash overdrafts (checks issued under zero balance accounts not yet presented for payment) in excess of cash balances in such accounts of approximately $110.6 million and $99.1 million at January 28, 2023 and January 29, 2022, respectively. The Company includes the change in book cash overdrafts in operating cash flows.
Insurance obligations	Insurance obligations. The Company uses a combination of insurance and self-insurance for a number of risk management activities, including workers’ compensation, general liability, and employee-related health care benefits. The self-insurance and deductible liability is determined actuarially, based on claims filed and an estimate of claims incurred but not yet reported.
Lease accounting	Lease accounting. As the Company’s leases generally do not provide an implicit discount rate, the Company uses the estimated collateralized incremental borrowing rate based on information available at the lease commencement date in determining the present value of lease payments for use in the calculation of the operating lease liabilities and right-of-use assets. This rate is determined using a portfolio approach based on the risk-adjusted rate of interest and requires estimates and assumptions including credit rating, credit spread, and adjustments for the impact of collateral. The Company believes that this is the rate it would have to pay to borrow an amount equal to the lease payments on a collateralized basis over a similar lease term. Operating lease liabilities and corresponding right-of-use assets include options to extend lease terms that are reasonably certain of being exercised. The Company does not record a lease liability and corresponding right-of-use asset for leases with terms of 12 months or less and accounts for lease and non-lease components as a single lease component. The Company’s lease portfolio is comprised of operating leases with the lease cost recorded on a straight-line basis over the lease term. Refer to Note E: Leases for additional information.
Store pre-opening	Store pre-opening. Store pre-opening costs are expensed in the period incurred.
Advertising	Advertising. Advertising costs are expensed in the period incurred and are included in Selling, general and administrative expenses.
Stock-based compensation	Stock-based compensation. The Company recognizes compensation expense based upon the grant date fair value of all stock-based awards, typically over the vesting period.
Taxes on earnings	Taxes on earnings. The Company accounts for income taxes in accordance with ASC 740, Accounting for Income Taxes, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been recognized in the Company’s consolidated financial statements or tax returns. In estimating future tax consequences, the Company generally considers all expected future events other than changes in the tax law or tax rates. ASC 740 clarifies the criteria that an individual tax position must satisfy for some or all of the benefits of that position to be recognized in a company’s consolidated financial statements. ASC 740 prescribes a recognition threshold of more-likely-than-not and a measurement standard for all tax positions taken or expected to be taken on a tax return in order for those tax positions to be recognized in the consolidated financial statements.
Treasury stock	Treasury stock. The Company records treasury stock at cost. Treasury stock includes shares purchased from employees for tax withholding purposes related to vesting of restricted stock grants.
Earnings per share ("EPS")	Earnings per share (“EPS”). The Company computes and reports both basic EPS and diluted EPS. Basic EPS is computed by dividing net earnings by the weighted-average number of common shares outstanding for the period. Diluted EPS is computed by dividing net earnings by the sum of the weighted-average number of common shares and dilutive common stock equivalents outstanding during the period. Diluted EPS reflects the total potential dilution that could occur from outstanding equity plan awards and unvested shares of both performance and non-performance based awards of restricted stock and restricted stock units. For periods of net loss, basic and diluted EPS are the same as the effect of the assumed vesting of restricted stock, restricted stock units, and performance share awards are anti-dilutive.
Recently issued and Recently adopted accounting standards	Recently issued accounting standards. In September 2022, the Financial Accounting Standards Board (“FASB”) issued ASU 2022-04, Liabilities — Supplier Finance Programs (Subtopic 405-50): Disclosure of Supplier Finance Program Obligations, to enhance transparency about an entity’s use of supplier finance programs. The ASU requires enhanced and additional disclosures about the key terms of supplier finance programs including a description of where in the financial statements any related amounts are presented. The initial guidance in the ASU will be effective for the Company for interim and annual reporting periods beginning after December 15, 2022, with early adoption permitted. The Company will begin adopting ASU 2022-04 as required at the beginning of fiscal 2023 and does not expect the adoption of this standard will have a material impact on the Company’s financial statement disclosures. Recently adopted accounting standards. In November 2021, the FASB issued ASU 2021-10, Government Assistance (Topic 832): Disclosures by Business Entities about Government Assistance, to increase the transparency of the effects of government assistance, including disclosure of the types of assistance an entity receives, an entity’s method of accounting for government assistance, and the effect of government assistance on an entity’s financial statements. The Company adopted ASU 2021-10 on a prospective basis as of January 28, 2023. The adoption of ASU 2021-10 did not have a material impact on the Company’s disclosures as of January 28, 2023. In December 2019, the FASB issued ASU 2019-12, Simplifying the Accounting for Income Taxes (ASC 740). ASU 2019-12 eliminates certain exceptions in ASC 740 related to the methodology for calculating income taxes in an interim period. It also clarifies and simplifies other aspects of the accounting for income taxes. The amendments in ASU 2019-12 are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020. Early adoption is permitted, including adoption in any interim period. The Company adopted ASU 2019-12 on a prospective basis in the first quarter of fiscal 2020. The most significant impact to the Company is the removal of a limit on the tax benefit recognized on pre-tax losses in interim periods. The adoption of this standard did not have a material impact on the Company’s fiscal 2020 results.
Fair value measurement	Accounting standards pertaining to fair value measurements establish a three-tier fair value hierarchy which prioritizes the inputs used in measuring fair value. The inputs used to measure fair value include: Level 1, observable inputs such as quoted prices in active markets; Level 2, inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3, unobservable inputs in which little or no market data exists. This fair value hierarchy requires the Company to develop its own assumptions and maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. Corporate, U.S. government and agency, and mortgage-backed securities are classified within Level 1 or Level 2 because these securities are valued using quoted market prices or alternative pricing sources and models utilizing market observable inputs.

The inputs used to measure fair value include: Level 1, observable inputs such as quoted prices in active markets; Level 2, inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3, unobservable inputs in which little or no market data exists. This fair value hierarchy requires the Company to develop its own assumptions and maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. Corporate, U.S. government and agency, and mortgage-backed securities are classified within Level 1 or Level 2 because these securities are valued using quoted market prices or alternative pricing sources and models utilizing market observable inputs.
