Accounting Policies [Abstract]

Summary of Significant Accounting Policies

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 2017, the Company operated 1,409 Ross Dress for Less^® (“Ross”) locations in 37 states, the District of Columbia, and Guam, and 213 dd’s DISCOUNTS^® stores in 16 states. The Ross and dd’s DISCOUNTS stores are supported by six distribution centers. The Company’s headquarters, one buying office, three operating distribution centers, two warehouses, and 23% of its stores are located in California.

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.

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. 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 February 3, 2018, January 28, 2017 and January 30, 2016 are referred to as fiscal 2017, fiscal 2016, and fiscal 2015, respectively. Fiscal 2017 was a 53-week year. Fiscal 2016 and 2015 were each 52-week years.

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. Actual results could differ from those estimates. The Company’s significant accounting estimates include valuation reserves for inventory shortage, packaway inventory costs, useful lives of fixed assets, insurance reserves, and reserves for uncertain tax positions.

Purchase obligations. As of February 3, 2018, the Company had purchase obligations of approximately $2.7 billion. These purchase obligations primarily consist of merchandise inventory purchase orders, commitments related to construction projects, store fixtures and supplies, and information technology service, transportation, and maintenance contracts.

Cash and cash equivalents. Cash equivalents consist of highly liquid, fixed income instruments purchased with an original maturity of three months or less.

Restricted cash, cash equivalents, and investments. The Company has restricted cash, cash equivalents, and investments that serve as collateral for certain insurance 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 following table summarizes total restricted cash, cash equivalents, and investments which were included in Prepaid expenses and other and Other long-term assets in the Consolidated Balance Sheets as of February 3, 2018 and January 28, 2017:



Restricted Assets ($000)	2017		2016
Prepaid expenses and other	$	11,847	$	13,642
Other long-term assets	53,969		54,567
Total	$	65,816	$	68,209

The classification between current and long-term is based on the timing of expected payments of the insurance obligations.

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. See Note B and Note D for additional fair value information.

Cash and cash equivalents were $1,290.3 million and $1,111.6 million, at February 3, 2018 and January 28, 2017, 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.

Investments. The Company’s investments are comprised of various debt securities. At February 3, 2018 and January 28, 2017, these investments were classified as available-for-sale and are stated at fair value. Investments are classified as either short- or long-term based on their maturity dates and the Company’s intent. Investments with a maturity of less than one year are classified as short-term. See Note B for additional information.

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 and 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, 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. 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 and warehouse facilities.

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 to 12 years for equipment and information systems and 20 to 40 years for land improvements and buildings. Depreciation and amortization expense on property and equipment was $313.2 million, $302.5 million, and $274.8 million for fiscal 2017, 2016, and 2015, respectively. The cost of leasehold improvements is amortized over the useful life of the asset or the applicable lease term, whichever is less. The Company capitalizes interest during the construction period. Interest capitalized was $0.7 million, $0.0 million and $6.5 million in fiscal 2017, 2016, and 2015, respectively. As of February 3, 2018, January 28, 2017, and January 30, 2016 the Company had $24.3 million, $25.7 million, and $35.8 million, respectively, of property and equipment purchased but not yet paid. These purchases are included in Property and Equipment and in Accounts payable and Accrued expenses and other in the accompanying Consolidated Balance Sheets.

Other long-term assets. Other long-term assets as of February 3, 2018 and January 28, 2017 consisted of the following:



($000)	2017		2016
Deferred compensation (Note B)	$	120,613	$	100,423
Restricted cash and investments	53,969		54,567
Other	13,136		11,976
Total	$	187,718	$	166,966

Property and other long-term assets that are subject to amortization are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. 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. Based on the Company’s evaluation during fiscal 2017, 2016, and 2015, no impairment charges were recorded.

Store closures. The Company continually reviews the operating performance of individual stores. For stores that are closed, the Company records a liability for future minimum lease payments net of estimated sublease recoveries and related ancillary costs at the time the liability is incurred. The lease loss liability was $0.6 million and $1.2 million, as of February 3, 2018 and January 28, 2017, respectively. Operating costs, including depreciation, of stores to be closed are expensed during the period they remain in use. In fiscal 2017, the Company closed seven stores. In fiscal 2016, the Company closed six stores.

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 $74.5 million and $96.3 million at February 3, 2018 and January 28, 2017, respectively. The Company includes the change in book cash overdrafts in operating cash flows.

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. Self-insurance and deductible reserves as of February 3, 2018 and January 28, 2017 consisted of the following:



($000)	2017		2016
Workers’ compensation	$	94,430	$	94,920
General liability	40,763		39,679
Medical plans	6,725		4,899
Total	$	141,918	$	139,498

Workers’ compensation and self-insured medical plan liabilities are included in Accrued payroll and benefits and accruals for general liability are included in Accrued expenses and other in the accompanying Consolidated Balance Sheets.

Other long-term liabilities. Other long-term liabilities as of February 3, 2018 and January 28, 2017 consisted of the following:

Lease accounting. When a lease contains “rent holidays” or requires fixed escalations of the minimum lease payments, the Company records rental expense on a straight-line basis over the term of the lease and the difference between the average rental amount charged to expense and the amount payable under the lease is recorded as deferred rent. The Company begins recording rent expense on the lease possession date. Tenant improvement allowances are included in Other long-term liabilities and are amortized over the lease term. Changes in tenant improvement allowances are included as a component of operating activities in the Consolidated Statements of Cash Flows.

Revenue recognition. The Company recognizes revenue at the point of sale and maintains an allowance for estimated future returns. 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. The Company recognizes income from stored value card breakage as a reduction of operating expenses when redemption by a customer is considered to be remote. Income recognized from breakage was not significant in fiscal 2017, 2016, and 2015.

Sales tax collected is not recognized as revenue and amounts outstanding are included in Accrued expenses and other in the Consolidated Balance Sheets.

Allowance for sales returns. An allowance for the gross margin loss on estimated sales returns is included in Accrued expenses and other in the Consolidated Balance Sheets. The allowance for sales returns consists of the following:



($000)	Beginning Balance		Additions		Returns			Ending Balance
Year ended:
February 3, 2018	$	8,406	$	784,076	$	(782,580	)	$	9,902
January 28, 2017	$	7,955	$	761,350	$	(760,899	)	$	8,406
January 30, 2016	$	8,594	$	737,727	$	(738,366	)	$	7,955

Store pre-opening. Store pre-opening costs are expensed in the period incurred.

Advertising. Advertising costs are expensed in the period incurred and are included in Selling, general and administrative expenses. Advertising costs for fiscal 2017, 2016, and 2015 were $76.4 million, $73.0 million, and $77.1 million, respectively.

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. See Note C for more information on the Company’s stock-based compensation plans.

Taxes on earnings. The Company accounts for income taxes in accordance with Accounting Standards Codification (“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. See Note F.

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”). 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, including unexercised stock options and unvested shares of both performance and non-performance based awards of restricted stock.

In fiscal 2017, 2016, and 2015 there were 2,800, 2,500, and 25,000 weighted average shares, respectively, that were excluded from the calculation of diluted EPS because their effect would have been anti-dilutive for those years.

The following is a reconciliation of the number of shares (denominator) used in the basic and diluted EPS computations:



Shares in (000s)	Basic EPS		Effect of dilutive common stock equivalents			Diluted EPS
2017
Shares	381,174		3,155			384,329
Amount	$	3.58	$	(0.03	)	$	3.55

2015
Shares	403,034		3,371			406,405
Amount	$	2.53	$	(0.02	)	$	2.51

Comprehensive income. Comprehensive income includes net earnings and components of other comprehensive income (loss), net of tax, consisting of unrealized investment gains or losses.

Recently issued accounting standards. In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (ASU) 2014-09, Revenue from Contracts with Customers (ASC 606). The guidance provides a five-step analysis of transactions to determine when and how revenue is recognized. The core principle of the guidance is that a company should recognize revenue when the customer obtains control of promised goods or services in an amount that reflects the consideration which the company expects to receive in exchange for those goods or services. ASC 606 is effective for the Company’s annual and interim reporting periods beginning in fiscal 2018. Adoption will result in a change in the timing of recognizing revenue from breakage for stored value cards. Breakage will be estimated and recognized based upon the historical pattern of redemption, rather than when redemption is considered remote. Additionally, the Company will recognize allowances for estimated sales returns on a gross rather than net basis in its Consolidated Financial Statements. The impact of estimating sales returns on a gross basis is not expected to be material. The Company plans to adopt ASC 606 under the modified retrospective method and will recognize a cumulative-effect adjustment to increase retained earnings by approximately $20 million, net of income taxes as of February 4, 2018.

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). The ASU requires balance sheet recognition for all leases with lease terms greater than one year including a lease liability, which is a lessee‘s obligation to make lease payments arising from a lease, measured on a discounted basis; and a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. ASU 2016-02 is effective for the Company’s annual and interim reporting periods beginning in fiscal 2019. The Company is currently working on its adoption plan and evaluating the effect adoption of this new guidance will have on its consolidated financial statements. Due to the substantial number of leases that it has, the Company believes this ASU will increase assets and liabilities by the same material amount on its consolidated balance sheet. The Company’s current undiscounted minimum commitments under noncancelable operating leases is approximately $3.7 billion. The Company does not believe adoption of this ASU will have a significant impact to its consolidated statements of earnings, stockholders’ equity, and cash flows.

In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash. ASU 2016-18 requires restricted cash and restricted cash equivalents be included with cash and cash equivalents when reconciling the total beginning and ending amounts on the statement of cash flows. The standard also requires companies who report cash and restricted cash separately on the balance sheet to reconcile those amounts to the statement of cash flows. ASU 2016-18 is effective for the Company’s annual and interim reporting periods beginning in fiscal 2018. The Company does not believe adoption of this ASU will have a significant impact to its consolidated financial statements.

Recently adopted accounting standards. In March 2016, the FASB issued ASU 2016-09, Compensation - Stock Compensation (Topic 718) - Improvements to Employee Share-Based Payment Accounting. ASU 2016-09 provides for changes to accounting for stock compensation including 1) excess tax benefits and tax deficiencies related to share based payment awards will be recognized as income tax benefit or expense in the reporting period in which they occur (previously such amounts were recognized in additional paid-in capital); 2) excess tax benefits will be classified as an operating activity in the statement of cash flows; and 3) the option to elect to estimate forfeitures or account for them when they occur. The impact of recording excess tax benefits in income taxes in our consolidated statement of earnings may be material, depending upon our future stock price on vest date in relation to the fair value of awards on grant date and our future grants of stock-based compensation.

The Company adopted ASU 2016-09 in the first quarter of fiscal 2017, and elected to apply this adoption prospectively, except for forfeitures which it adopted on a modified retrospective basis. Accordingly, prior periods have not been adjusted. As a result of adoption, for the fiscal year ended February 3, 2018, the Company recognized $16.3 million of excess tax benefits related to stock-based payments as a reduction to its provision for income taxes. These items were historically recorded in additional paid-in capital. The Company also presented cash flows related to excess tax benefits as an operating activity in the Consolidated Statement of Cash Flows and elected to account for forfeitures as incurred beginning on January 29, 2017. The impact of this accounting policy election for forfeitures was a cumulative-effect adjustment to decrease retained earnings by $1.1 million, net of tax, as of January 29, 2017.

Fair Value Disclosures [Abstract]

Investments And Restricted Investments

Investments and Restricted Investments

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.

There were no transfers between Level 1 and Level 2 categories during the fiscal year ended February 3, 2018. The fair value of the Company’s financial instruments as of February 3, 2018 and January 28, 2017 are as follows:



($000)	2017		2016
Cash and cash equivalents (Level 1)	$	1,290,294	$	1,111,599

Investments (Level 2)	$	1,224	$	1,288

Restricted cash and cash equivalents (Level 1)	$	62,978	$	64,581

Restricted investments (Level 2)	$	2,838	$	3,628

The underlying assets in the Company’s non-qualified deferred compensation program as of February 3, 2018 and January 28, 2017 (included in Other long-term assets and in Other long-term liabilities) primarily consist of participant-directed money market, stable value, stock, and bond funds. The fair value measurement for funds with quoted market prices in active markets (Level 1) and for funds without quoted market prices in active markets (Level 2) are as follows:



($000)	2017		2016
Level 1	$	104,590	$	84,933

Leases [Abstract]

Leases

The Company currently leases all but two of its store locations with original, non-cancelable terms that in general range from three to ten years. In November 2017, the Company entered into a sale-leaseback transaction on one of its previously owned stores. The Company received net cash proceeds of $16.0 million, recognized a gain on sale of $6.3 million, and deferred the residual $7.5 million gain over the remaining ten-year lease term. Store leases typically contain provisions for three to four renewal options of five years each. Most store leases also provide for minimum annual rentals and for payment of certain expenses. In addition, some store leases also have provisions for additional rent based on a percentage of sales.

The Company leases three warehouses. Two of the warehouses are in Carlisle, Pennsylvania with leases expiring in 2018 and 2019. The third warehouse is in Fort Mill, South Carolina, with a lease expiring in 2024. All of the warehouse leases contain renewal provisions.

The Company leases approximately 87,000 and 5,000 square feet of office space for its Los Angeles and Boston buying offices, respectively. The lease term for these facilities expire in 2022 and 2020, respectively, and contain renewal provisions. In addition, the Company has a ground lease related to its New York buying office.

The aggregate future minimum annual lease payments under leases, including the ground lease related to the New York buying office, in effect at February 3, 2018 are as follows:



($000)	Total operating leases
2018	$	516,372

Prior to adoption of ASU 2016-09, the Company realized tax benefits of $23.3 million and $42.4 million in 2016 and 2015, respectively, related to employee equity programs that were recorded in additional paid-in capital. In fiscal 2017, the Company adopted ASU 2016-09 and realized tax benefits of $16.3 million as a reduction to its provision for income taxes.

The provision for taxes for financial reporting purposes is different from the tax provision computed by applying the statutory federal income tax rate. The differences are reconciled below:



	2017		2016		2015
Federal income taxes at the statutory rate	34	%	35	%	35	%
Impact of the Tax Cuts and Jobs Act on deferred taxes	(3	)%	—		—
State income taxes (net of federal benefit) and other, net	2	%	2	%	2	%
Total	33	%	37	%	37	%

The Tax Cuts and Jobs Act (the “Tax Act” or "tax reform") was signed into law on December 22, 2017. The Tax Act made significant changes to U.S. corporate taxation including reducing the U.S. federal corporate income tax rate from 35% to 21% effective January 1, 2018, permitting immediate capital expensing of certain qualified property, and limiting the tax deductions available for certain executive compensation and employee fringe benefits. U.S. GAAP requires that the impact of tax legislation be recognized in the period in which the law was enacted. As a result, the Company applied a blended U.S. federal income tax rate of approximately 34% for fiscal 2017, due to the lower tax rate of 21% becoming effective in the last month of that fiscal year. This reduced tax rate resulted in a tax benefit of $24.9 million. The Company recorded an additional tax benefit of $55.2 million due to the remeasurement of its deferred tax assets and liabilities. Both of these tax benefits were recorded in the fourth quarter of fiscal 2017. Also on December 22, 2017, the SEC staff issued Staff Accounting Bulletin 118, Income Tax Accounting Implications of the Tax Cuts and Jobs Act (“SAB 118”), which provides guidance on accounting for the impact of the Tax Act. As permitted by SAB 118, both of the tax benefits recorded by the Company in fiscal 2017, represent provisional amounts based on the Company’s current best estimates. Any adjustments made to those provisional amounts will be included in income from operations and recorded as an adjustment to tax expense through the fiscal year ending February 2, 2019. The recorded, provisional amounts reflect assumptions made based upon the Company’s current interpretation of the Tax Act, and may change as the Company receives additional clarification and guidance in the form of technical corrections to the Tax Act or regulations issued by the U.S. Treasury.

The components of deferred taxes at February 3, 2018 and January 28, 2017 are as follows:

At the end of fiscal 2017 and 2016, the Company’s state tax credit carryforwards for income tax purposes were approximately $14.7 million and $22.8 million, respectively. The state tax credit carryforwards will begin to expire in fiscal 2019. The Company has provided a valuation allowance of $4.7 million as of the end of fiscal 2017 for deferred tax assets related to state tax credits that are not expected to be realized.

The changes in amounts of unrecognized tax benefits (gross of federal tax benefits and excluding interest and penalties) at fiscal 2017, 2016, and 2015 are as follows:



($000)	2017			2016			2015
Unrecognized tax benefits - beginning of year	$	81,122		$	75,372		$	78,116

Unrecognized tax benefits - end of year	$	98,666		$	81,122		$	75,372

At the end of fiscal 2017, 2016, and 2015, the reserves for unrecognized tax benefits were $121.3 million, $98.6 million, and $94.2 million inclusive of $22.6 million, $17.5 million, and $18.8 million of related interest and penalties, respectively. The Company accounts for interest and penalties related to unrecognized tax benefits as a part of its provision for taxes on earnings. If recognized, $81.3 million would impact the Company’s effective tax rate. The difference between the total amount of unrecognized tax benefits and the amounts that would impact the effective tax rate relates to amounts attributable to deferred tax assets and liabilities. These amounts are net of federal and state income taxes.

It is reasonably possible that certain federal and state tax matters may be concluded or statutes of limitations may lapse during the next twelve months. Accordingly, the total amount of unrecognized tax benefits may decrease by up to $8.8 million.

The Company is open to audit by the Internal Revenue Service under the statute of limitations for fiscal years 2013 through 2017. The Company’s state income tax returns are generally open to audit under the various statutes of limitations for fiscal years 2013 through 2017. Certain federal and state tax returns are currently under audit by various tax authorities. The Company does not expect the results of these audits to have a material impact on the consolidated financial statements.

Employee Benefit Plans	12 Months Ended
Employee Benefit Plans	Feb. 03, 2018
Defined Contribution Plan [Abstract]
Employee Benefit Plans	Employee Benefit Plans The Company has a defined contribution plan that is available to certain employees. Under the plan, employee and Company contributions and accumulated plan earnings qualify for favorable tax treatment under Section 401(k) of the Internal Revenue Code. This plan permits employees to make contributions up to the maximum limits allowable under the Internal Revenue Code. The Company matches up to 4% of the employee’s salary up to the plan limits. Company matching contributions to the 401(k) plan were $15.4 million, $13.9 million, and $12.7 million in fiscal 2017, 2016, and 2015, respectively. The Company also has an Incentive Compensation Plan which provides cash awards to key management and employees based on Company and individual performance. The Company also makes available to management a Non-qualified Deferred Compensation Plan which allows management to make payroll contributions on a pre-tax basis in addition to the 401(k) plan.

Plan investments are designated by the participants, and investment returns are not guaranteed by the Company. The Company has a corresponding liability to participants of $120.6 million and $100.4 million at February 3, 2018 and January 28, 2017, respectively, included in Other long-term liabilities in the Consolidated Balance Sheets.

Stockholders’ Equity

Common stock. In February 2017, the Company’s Board of Directors approved a two-year $1.75 billion stock repurchase program through fiscal 2018. In March 2018, the Company’s Board of Directors approved an increase in the stock repurchase authorization for fiscal 2018 by $200 million to $1.075 billion, up from the previously available $875 million.

The following table summarizes the Company’s stock repurchase activity in fiscal 2017, 2016, and 2015:



Fiscal Year	Shares repurchased (in millions)	Average repurchase price	Repurchased (in millions)
2017	13.5	$64.87	$875
2016	11.6	$60.15	$700
2015	13.7	$51.27	$700

Preferred stock. The Company has four million shares of preferred stock authorized, with a par value of $.01 per share. No preferred stock is issued or outstanding.

Dividends. On March 6, 2018, the Company’s Board of Directors declared a quarterly cash dividend of $0.2250 per common share, payable on March 30, 2018. The Company’s Board of Directors declared cash dividends of $0.1600 per common share in February, May, August, and November 2017, cash dividends of $0.1350 per common share in March, May, August, and November 2016, and cash dividends of $0.1175 per common share in February, May, August, and November 2015.

2017 Equity Incentive Plan. On May 17, 2017, the Company’s stockholders approved the Ross Stores, Inc. 2017 Equity Incentive Plan (the “2017 Plan”) which replaced the Company’s 2008 Equity Incentive Plan (“Predecessor Plan”). The 2017 Plan, which was authorized to issue a maximum of 12.0 million shares, was immediately effective upon approval and no further awards were granted under the Predecessor Plan, which was terminated.

The 2017 Plan has an initial share reserve of 12.0 million shares of the Company’s common stock which can be increased by a maximum of 5.5 million shares from certain expired, withheld, or forfeited shares from the 2017 Plan or the Predecessor Plan. The 2017 Plan provides for various types of incentive awards, which may potentially include the grant of stock options, stock appreciation rights, restricted stock purchase rights, restricted stock bonuses, restricted stock units, performance shares, performance units, and deferred compensation awards. As of February 3, 2018, there were 11.9 million shares available for grant under the 2017 Plan.

As of February 3, 2018, all remaining options under the 2017 Plan or Predecessor Plan had been exercised and there were no remaining outstanding and exercisable options.

A summary of restricted stock and performance share award activity for fiscal 2017 is presented below:



	Number of shares (000)		Weighted average grant date fair value
Unvested at January 28, 2017	5,563		$43.19
Awarded	1,543		65.56
Released	(1,583	)	37.97
Forfeited	(40	)	50.21
Unvested at February 3, 2018	5,483		$51.19

The market value of shares of restricted stock and performance shares at the date of grant is amortized to expense over the vesting period of generally three to five years. The unamortized compensation expense at February 3, 2018 and January 28, 2017 was $114.0 million and $101.6 million, respectively, which is expected to be recognized over a weighted average remaining period of 1.8 years. Intrinsic value for restricted stock, defined as the closing market value on the last business day of fiscal year 2017 (or $79.08), was $433.6 million. A total of 11.9 million, 12.1 million, and 12.7 million shares were available for new restricted stock awards at the end of fiscal 2017, 2016, and 2015, respectively. During fiscal 2017, 2016, and 2015, shares purchased by the Company for tax withholding totaled 0.7 million, 0.7 million, and 1.3 million shares, respectively, and are considered treasury shares which are available for reissuance. As of February 3, 2018 and January 28, 2017, the Company held 12.5 million and 11.8 million shares of treasury stock, respectively.

Performance share awards. The Company has a performance share award program for senior executives. A performance share award represents a right to receive shares of restricted stock on a specified settlement date based on the Company’s attainment of a profitability-based performance goal during the performance period, which is the Company’s fiscal year. If attained, the restricted stock then vests over a service period, generally two to three years from the date the performance award was granted. The Company issued approximately 655,000, 682,000, and 601,000 shares in settlement of the fiscal 2017, 2016, and 2015 awards.

Employee Stock Purchase Plan. Under the Employee Stock Purchase Plan (“ESPP”), eligible employees participating in the quarterly offering period can choose to have up to the lesser of 10% of their annual base earnings or the IRS annual share purchase limit of $25,000 in aggregate market value to purchase the Company’s common stock. The purchase price of the stock is 85% of the closing market price on the date of purchase. Purchases occur on a quarterly basis (on the last trading day of each calendar quarter). The Company recognizes expense for ESPP purchase rights equal to the value of the 15% discount given on the purchase date.

During fiscal 2017, 2016, and 2015, employees purchased approximately 0.3 million, 0.3 million, and 0.4 million shares, respectively, of the Company’s common stock under the plan at weighted average per share prices of $56.42, $51.86, and $43.16, respectively. Through February 3, 2018, approximately 39.7 million shares had been issued under this plan and 5.3 million shares remained available for future issuance.

Summary of Significant Accounting Policies (Policies)	Feb. 03, 2018
Accounting Policies [Abstract]
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 2017, the Company operated 1,409 Ross Dress for Less^® (“Ross”) locations in 37 states, the District of Columbia, and Guam, and 213 dd’s DISCOUNTS^® stores in 16 states. The Ross and dd’s DISCOUNTS stores are supported by six distribution centers. The Company’s headquarters, one buying office, three operating distribution centers, two warehouses, and 23% of its stores are located in California.
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.
Basis of presentation and fiscal year	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. 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 February 3, 2018, January 28, 2017 and January 30, 2016 are referred to as fiscal 2017, fiscal 2016, and fiscal 2015, respectively. Fiscal 2017 was a 53-week year. Fiscal 2016 and 2015 were each 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. Actual results could differ from those estimates. The Company’s significant accounting estimates include valuation reserves for inventory shortage, packaway inventory costs, useful lives of fixed assets, insurance reserves, and reserves for uncertain tax positions.
Purchase obligations	These purchase obligations primarily consist of merchandise inventory purchase orders, commitments related to construction projects, store fixtures and supplies, and information technology service, transportation, and maintenance contracts.
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.
Restricted cash, cash equivalents, and investments	Restricted cash, cash equivalents, and investments. The Company has restricted cash, cash equivalents, and investments that serve as collateral for certain insurance 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.
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. See Note B and Note D for additional fair value information. Cash and cash equivalents were $1,290.3 million and $1,111.6 million, at February 3, 2018 and January 28, 2017, 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.
Investments	Investments. The Company’s investments are comprised of various debt securities. At February 3, 2018 and January 28, 2017, these investments were classified as available-for-sale and are stated at fair value. Investments are classified as either short- or long-term based on their maturity dates and the Company’s intent. Investments with a maturity of less than one year are classified as short-term.
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 and 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, 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	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 and warehouse facilities.
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 to 12 years for equipment and information systems and 20 to 40 years for land improvements and buildings. Depreciation and amortization expense on property and equipment was $313.2 million, $302.5 million, and $274.8 million for fiscal 2017, 2016, and 2015, respectively. The cost of leasehold improvements is amortized over the useful life of the asset or the applicable lease term, whichever is less. The Company capitalizes interest during the construction period.
Other long-term assets	Property and other long-term assets that are subject to amortization are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. 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.
Store closures	Store closures. The Company continually reviews the operating performance of individual stores. For stores that are closed, the Company records a liability for future minimum lease payments net of estimated sublease recoveries and related ancillary costs at the time the liability is incurred. The lease loss liability was $0.6 million and $1.2 million, as of February 3, 2018 and January 28, 2017, respectively. Operating costs, including depreciation, of stores to be closed are expensed during the period they remain in use.
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 $74.5 million and $96.3 million at February 3, 2018 and January 28, 2017, 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. When a lease contains “rent holidays” or requires fixed escalations of the minimum lease payments, the Company records rental expense on a straight-line basis over the term of the lease and the difference between the average rental amount charged to expense and the amount payable under the lease is recorded as deferred rent. The Company begins recording rent expense on the lease possession date. Tenant improvement allowances are included in Other long-term liabilities and are amortized over the lease term. Changes in tenant improvement allowances are included as a component of operating activities in the Consolidated Statements of Cash Flows.
Revenue recognition	Revenue recognition. The Company recognizes revenue at the point of sale and maintains an allowance for estimated future returns. 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. The Company recognizes income from stored value card breakage as a reduction of operating expenses when redemption by a customer is considered to be remote. Income recognized from breakage was not significant in fiscal 2017, 2016, and 2015. Sales tax collected is not recognized as revenue and amounts outstanding are included in Accrued expenses and other in the Consolidated Balance Sheets.
Allowance for sales returns	Allowance for sales returns. An allowance for the gross margin loss on estimated sales returns is included in Accrued expenses and other in the Consolidated Balance Sheets.
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.
Share-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 Accounting Standards Codification (“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, including unexercised stock options and unvested shares of both performance and non-performance based awards of restricted stock.
Comprehensive income	Comprehensive income. Comprehensive income includes net earnings and components of other comprehensive income (loss), net of tax, consisting of unrealized investment gains or losses.
Recently issued and adopted accounting standards	Recently issued accounting standards. In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (ASU) 2014-09, Revenue from Contracts with Customers (ASC 606). The guidance provides a five-step analysis of transactions to determine when and how revenue is recognized. The core principle of the guidance is that a company should recognize revenue when the customer obtains control of promised goods or services in an amount that reflects the consideration which the company expects to receive in exchange for those goods or services. ASC 606 is effective for the Company’s annual and interim reporting periods beginning in fiscal 2018. Adoption will result in a change in the timing of recognizing revenue from breakage for stored value cards. Breakage will be estimated and recognized based upon the historical pattern of redemption, rather than when redemption is considered remote. Additionally, the Company will recognize allowances for estimated sales returns on a gross rather than net basis in its Consolidated Financial Statements. The impact of estimating sales returns on a gross basis is not expected to be material. The Company plans to adopt ASC 606 under the modified retrospective method and will recognize a cumulative-effect adjustment to increase retained earnings by approximately $20 million, net of income taxes as of February 4, 2018. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). The ASU requires balance sheet recognition for all leases with lease terms greater than one year including a lease liability, which is a lessee‘s obligation to make lease payments arising from a lease, measured on a discounted basis; and a right-of-use asset, which is an asset that represents the lessee’s right to use, or control the use of, a specified asset for the lease term. ASU 2016-02 is effective for the Company’s annual and interim reporting periods beginning in fiscal 2019. The Company is currently working on its adoption plan and evaluating the effect adoption of this new guidance will have on its consolidated financial statements. Due to the substantial number of leases that it has, the Company believes this ASU will increase assets and liabilities by the same material amount on its consolidated balance sheet. The Company’s current undiscounted minimum commitments under noncancelable operating leases is approximately $3.7 billion. The Company does not believe adoption of this ASU will have a significant impact to its consolidated statements of earnings, stockholders’ equity, and cash flows. In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash. ASU 2016-18 requires restricted cash and restricted cash equivalents be included with cash and cash equivalents when reconciling the total beginning and ending amounts on the statement of cash flows. The standard also requires companies who report cash and restricted cash separately on the balance sheet to reconcile those amounts to the statement of cash flows. ASU 2016-18 is effective for the Company’s annual and interim reporting periods beginning in fiscal 2018. The Company does not believe adoption of this ASU will have a significant impact to its consolidated financial statements. Recently adopted accounting standards. In March 2016, the FASB issued ASU 2016-09, Compensation - Stock Compensation (Topic 718) - Improvements to Employee Share-Based Payment Accounting. ASU 2016-09 provides for changes to accounting for stock compensation including 1) excess tax benefits and tax deficiencies related to share based payment awards will be recognized as income tax benefit or expense in the reporting period in which they occur (previously such amounts were recognized in additional paid-in capital); 2) excess tax benefits will be classified as an operating activity in the statement of cash flows; and 3) the option to elect to estimate forfeitures or account for them when they occur. The impact of recording excess tax benefits in income taxes in our consolidated statement of earnings may be material, depending upon our future stock price on vest date in relation to the fair value of awards on grant date and our future grants of stock-based compensation. The Company adopted ASU 2016-09 in the first quarter of fiscal 2017, and elected to apply this adoption prospectively, except for forfeitures which it adopted on a modified retrospective basis. Accordingly, prior periods have not been adjusted. As a result of adoption, for the fiscal year ended February 3, 2018, the Company recognized $16.3 million of excess tax benefits related to stock-based payments as a reduction to its provision for income taxes. These items were historically recorded in additional paid-in capital. The Company also presented cash flows related to excess tax benefits as an operating activity in the Consolidated Statement of Cash Flows and elected to account for forfeitures as incurred beginning on January 29, 2017. The impact of this accounting policy election for forfeitures was a cumulative-effect adjustment to decrease retained earnings by $1.1 million, net of tax, as of January 29, 2017.
