Summary of Significant Accounting Policies

2. Summary of Significant Accounting Policies

Basis of Presentation

The accompanying interim financial statements of BJ’s Wholesale Club Holdings, Inc. are unaudited and, in the opinion of management, reflect all normal recurring adjustments considered necessary for a fair statement of the Company’s financial statements in accordance with generally accepted accounting principles in the United States of America. References to “BJ’s” or the “Company” refer to BJ’s Wholesale Club Holdings, Inc. and its consolidated subsidiaries, unless the context indicates otherwise.

The consolidated balance sheet as of February 3, 2018 is derived from the audited consolidated balance sheet as of that date. The unaudited results of operations for the quarter ended August 4, 2018 are not necessarily indicative of future results or results to be expected for the full year ending February 2, 2019. The Company’s business, in common with the business of retailers generally, is subject to seasonal influences. The Company’s sales and operating income have typically been highest in the fourth quarter holiday season and lowest in the first quarter of each fiscal year.

You should read these statements in conjunction with the Company’s audited consolidated financial statements and related notes starting in page F-1 of the Company’s final prospectus for its IPO filed pursuant to Rule 424(b)(4) under the Securities Act with the SEC on June 28, 2018 (the “Prospectus”).

Initial Public Offering

On July 2, 2018, the Company completed its IPO, in which the Company issued and sold 43,125,000 shares of its common stock (including 5,625,000 shares of common stock that were subject to the underwriters’ option to purchase additional shares) at an initial public offering price of $17.00 per share. The Company received total aggregate proceeds of $685.9 million net of underwriters discounts, commissions and other transaction expenses, which totaled $47.2 million.

On July 2, 2018, the Company used the net proceeds from the IPO to extinguish the total outstanding balance of $623.3 million of its senior secured second lien term loan facility (the “Second Lien Term Loan”). See Note 6, Debt and Credit Arrangements footnote, for further discussion regarding the Second Lien Term Loan extinguishment.

Stock Split

On June 15, 2018, the Company effected a seven-to-one stock split of its issued and outstanding shares of common stock and proportional adjustment to the existing conversion ratios for each series of the Company’s Contingently Redeemable Common Stock (see Note 10). Accordingly, all shares and per share amounts for all periods presented in the accompanying consolidated financial statements and notes thereto have been adjusted retroactively, where applicable, to reflect this stock split and adjustment of the contingently redeemable common stock conversion ratios.

Deferred Offering Costs

The Company capitalized certain legal, professional, accounting and other third-party fees that were directly associated with the IPO as deferred offering costs. Upon the consummation of the IPO, $47.2 million were recorded in stockholders’ deficit as a reduction of additional paid-in capital.

Recent Accounting Pronouncements

The accounting policies the Company follows are set forth in the Company’s audited financial statements for the fiscal year ended February 3, 2018 and included in the Company’s final Prospectus. There have been no material changes to these accounting policies, except as noted below for new accounting pronouncements adopted at the beginning of fiscal year 2018.

Revenue from Contracts with Customers (ASC No. 606)

In May 2014, the Financial Accounting Standards Board (“FASB”) issued ASU 2014-09, Revenue from Contracts with Customers (“ASC No. 606”), which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The ASU replaced most existing revenue recognition guidance in U.S. GAAP as of its effective date.

The Company adopted the new guidance at the beginning of fiscal year 2018 using the modified retrospective adoption method and recognized the cumulative effect of initially applying the new guidance as an adjustment to the opening balance of accumulated deficit. The new guidance was only applied to contracts not completed as of the initial date of application. Additionally, any contract that was modified prior to the adoption date has been reflected in the cumulative adjustment giving effect to the aggregate effect of all contract modifications prior to the initial application date. The impact of employing this practical expedient for contract modifications is immaterial. The comparative information has not been restated and continues to be reported under the accounting standards in effect for those periods. The cumulative effect of the changes made to the Company’s February 3, 2018 balance sheet for the adoption of the standard update was as follows (in thousands):


	Balance as of February 3, 2018			Adjustment for new Standard			Balance as of February 4, 2018
Prepaid expenses and other current assets	$	81,972		$	7,820		$	89,792
Accrued expenses and other current liabilities		495,767			16,645			512,412
Deferred income taxes		57,074			(2,463	)		54,611
Accumulated deficit		(1,036,012	)		(6,362	)		(1,042,374	)

The impact of the adoption of the standards update on the Company’s Consolidated Statement of Operations for the thirteen and twenty-six weeks ended August 4, 2018, resulted in a decrease to cost of sales and net sales of $1.1 million and $5.7 million, respectively, due to recording the allowance for returns reserve on a gross basis. The remaining impact of the adoption of the standards on the Company’s Consolidated Statement of Operations for the thirteen weeks and twenty-six weeks ended August 4, 2018 was immaterial.

The impact of the adoption of the standards update on the Company’s Consolidated Balance Sheet as of August 4, 2018 was as follows (in thousands):


	As of August 4, 2018,
	As Reported			Balance without adoption			Effect of change
Prepaid expenses and other current assets	$	69,116		$	62,270		$	6,846
Accrued expenses and other current liabilities		473,500			457,531			15,969
Deferred income taxes		52,988			55,586			(2,598	)
Accumulated deficit		(1,033,851	)		(1,027,325	)		(6,526	)

Classification of Costs Related to Defined Benefit Pension and Other Post-Retirement Benefit Plans (ASU 2017-07)

At the beginning of fiscal year 2018, the Company adopted ASU No. 2017-07, Compensation—Retirement Benefits (Topic 715: Improving the Presentation of Net Periodic Pension Cost and Net Periodic Post-Retirement Benefit Cost (“ASU 2017-07”). ASU 2017-07 changes how employers that sponsor defined benefit pension and/or other post-retirement benefit plans present the net periodic benefit costs in the statement of operations. Under this new guidance, an employer’s statement of operations presents service cost arising in the current period in the same statement line item as other employee compensation. However, all other components of current period costs related to defined benefit plans, such as prior service costs and actuarial gains and losses, are presented on the statement of operations on a line item outside (or below) operating income. ASU 2017-07 affects only the classification of certain costs on the statement of operations, not the determination of costs. Net periodic pension costs related to the Company’s frozen defined benefit pension plan and post-retirement medical benefit plan were not material for the second quarter of fiscal year 2018 or prior periods. The retrospective impacts of this standard on our historical financial statements are not material and will not be restated on future filings.

Modifications to Share-based Compensation Awards (ASU 2017-09)

At the beginning of fiscal year 2018, the Company adopted ASU No. 2017-09, Compensation-Stock Compensation Topic 718-Scope of Modification Accounting (“ASU 2017-09”). ASU 2017-09 clarifies when changes to the terms and conditions of share-based payment awards must be accounted for as modifications. Entities apply the modification accounting guidance if the value, vesting conditions, or classification of an award changes. The Company has not modified any share-based payment awards. Should the Company modify share-based payment awards in the future, it will apply the provisions of ASU 2017-09.

Definition of a Business (ASU 2017-01)

At the beginning of fiscal year 2018, the Company adopted ASU No. 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business (“ASU 2017-01”). ASU 2017-01 assists entities in determining if acquired assets constitute the acquisition of a business or the acquisition of assets for accounting and reporting purposes. This distinction is important because goodwill can only be recognized in an acquisition of a business. Prior to ASU 2017-01, if revenues were generated immediately before and after a transaction, the acquisition was typically considered a business. Under ASU 2017-01, entities are required to further assess the substance of the processes they acquire. Should the Company commence or complete an acquisition in future periods, it will apply the provisions of ASU 2017-01.

Statement of Cash Flows (ASU 2016-15)

At the beginning of fiscal year 2018, the Company adopted ASU No. 2016-15, Statement of Cash Flows (Topic 230) (“ASU 2016-15”). ASU 2016-15 represents a consensus of the FASB’s Emerging Issues Task Force on eight separate issues that, if present, can impact classifications on the statement of cash flows. The guidance requires application using a retrospective transition method. The adoption of ASU 2016-15 only impacted the classification of certain insurance proceeds on the Company consolidated statement of cash flows for the first quarter of fiscal year 2017. The Company’s insurance proceeds were $2.0 million for the second quarter of fiscal year 2018 and were not material for the second quarter of fiscal year 2017. The retrospective impacts of this standard on our historical financial statements are not material and will not be restated on future filings.

Recently Issued Accounting Pronouncements

In February 2016, the FASB issued ASU 2016-02, which requires lessees to recognize a right-of-use asset and a lease liability, initially measured at the present value of the lease payments for all leases with a term greater than 12 months. This standard is effective for annual reporting periods, and interim periods therein, beginning after December 15, 2018 and is required to be applied using a modified retrospective approach for all leases existing at, or entered into after, the beginning of the earliest comparative period presented. The Company has a significant number of leases, and as a result, expects this guidance to have a material impact on its Consolidated Balance Sheet, the impact of which is currently being evaluated.

Revenue Recognition

Revenue from Contract with Customer [Abstract]

Revenue Recognition

3. Revenue Recognition

At the beginning of fiscal year 2018, the Company adopted the provisions of ASC No. 606, Revenue from Contracts with Customers, and related amendments (“ASC 606”) using the modified retrospective adoption method. The following describes the changes to the Company’s accounting policies due to the adoption of ASC 606:

Revenue Recognition

The Company uses the five-step model to recognize revenue:

1)

Identify the contract with the customer

2)

Identity the performance obligation(s)

3)

Determine the transaction price

4)

Allocate the transaction price to each performance obligation if multiple obligations exist

5)

Recognize the revenue as the performance obligations are satisfied

Performance Obligations

The Company identifies each distinct performance obligation to transfer goods (or bundle of goods) or services. The Company recognizes revenue when (or as) it satisfies a performance obligation by transferring control of the goods or services to the customer.

Merchandise sales—The Company recognizes sale of merchandise at clubs and gas stations at the point of sale when the customer takes possession of the goods and tenders payment. At point of sale, the performance obligation is satisfied because control of the merchandise transfers to the customer. Sales of merchandise at the Company’s clubs and gas stations, excluding sales taxes, represent approximately 98% of the Company’s net sales and approximately 95% of the Company’s total revenues. Sales taxes are recorded as a liability at the point of sale. Revenue is recorded at the point of sale based on the transaction price on the merchandise tag, net of any applicable discounts, sales taxes and expected refund. For e-commerce sales, the Company recognizes sales when control of the merchandise is transferred to the customer, which is typically at the shipping point.

BJ’s Perks Rewards—The Company has a customer loyalty program called the BJ’s Perks Rewards^® Program for which the Company offers points based on dollars spent by the customer. The Company also has a co-branded credit card program which provides members additional reward dollars for certain purchases. The Company’s BJ’s Perks Rewards^® members earn 2% cash back, up to a maximum of $500 per year, on all qualified purchases made at BJ’s. The Company’s My BJ’s Perks Mastercard holders earn 3% or 5% cash back on all qualified purchases made at BJ’s and 1% or 2% cash back on purchases made with the card outside of BJ’s. Cash back is in the form of electronic awards issued in $20 increments that may be used online or in-club at the register and expire six months from the date issued.

Earned rewards may be redeemed on future purchases made at the Company. The Company recognizes revenue for earned rewards when customers redeem such rewards as part of a purchase at one of the Company’s clubs or the Company’s website. The Company accounts for these transactions as multiple element arrangements and allocates the transaction price to separate performance obligations using their relative fair values. The Company includes the fair value of reward dollars earned in deferred revenue at the time the reward dollars are earned.

Royalty revenue received in connection with the co-brand credit card program is variable consideration and is considered constrained until the card holder makes a purchase.

The Company’s total deferred revenue related to the outstanding BJ’s Perks Rewards^® was $12.9 million at August 4, 2018. The timing of revenue recognition of these reward dollars is driven by actual customer activities, such as redemptions and expirations. The Company recognized $22.0 million of royalty revenue in the first half of 2018. The Company expects to recognize $8.9 million of the deferred revenue at August 4, 2018 in fiscal year 2018, and the remainder will be recognized in the years thereafter.

Membership – The Company charges a membership fee to its customers. That fee allows customers to shop in the Company’s clubs, shop on the Company’s website and purchase gas at the Company’s gas stations for the duration of the membership, which is 12 months. Because the Company has the obligation to provide access to its clubs, website and gas stations for the duration of the membership term, the Company recognizes membership fees on a straight-line basis over the life of the membership. The Company’s deferred revenue related to membership fees was $129.9 million at August 4, 2018.

Gift Card Programs – The Company sells gift cards that allow the customer to redeem the card for future purchases equal to the amount of the original purchase price of the gift card. Revenue from gift card sales is recognized upon redemption of the gift card because the Company’s performance obligation to redeem the gift card for merchandise is satisfied when the gift card is redeemed. Historically, the Company has recognized breakage under the remote model, which recognizes breakage income when the likelihood of the customer exercising its remaining rights becomes remote. Under the new guidance the Company recognizes breakage in proportion to its rate of gift card redemptions. This change in breakage recognition model resulted in a $1.8 million increase to accumulated deficit upon adoption and had an immaterial impact on the Company’s results of operations for the twenty-six weeks ended August 4, 2018. Deferred revenue related to gift cards was $8.8 million immediately after the adoption and $9.5 million at August 4, 2018. The Company recognized $21.4 million of revenue from gift card redemptions in the first half of 2018 and expects to recognize approximately $9.0 million of the second quarter deferral in fiscal year 2018.

Determine the Transaction Price

The transaction price is the amount of consideration the Company expects to receive under the arrangement. The Company is required to estimate variable consideration (if any) and to factor that estimate into the determination of the transaction price. The Company may offer sales incentives to customers, including discounts. For retail transactions, the Company has significant experience with return patterns and relies on this experience to estimate expected returns when determining the transaction price.

Returns and Refunds—The Company’s products are generally sold with a right of return and may provide other credits or incentives, which are accounted for as variable consideration when estimating the amount of revenue to recognize. The Company records an allowance for returns based on current period revenues and historical returns experience. The Company analyzes actual historical returns, current economic trends and changes in sales volume and acceptance of the Company’s products when evaluating the adequacy of the sales returns allowance in any accounting period.

Customer Discounts—Discounts given to customers are usually in the form of coupons and instant markdowns are recognized as redeemed and recorded in contra revenue accounts, as they are part of the transaction price of the merchandise sale. Manufacturer coupons that are available for redemption at all retailers are not reduced from the sale price of merchandise.

Agent Relationships

Ancillary Business Revenue – The Company enters into certain agreements with service providers that offer goods and services to the Company’s members. These service providers sell goods and services including home improvement services, vision care and cell phones to the Company’s customers. In exchange, the Company receives payments in the form of commissions and other fees. The Company evaluates the criteria outlined in ASC 606-10-55, Principal versus Agent Considerations, in determining whether it is appropriate in these arrangements to record the gross amount of merchandise sales and related costs, or the net amount earned as commissions. When the Company is considered the principal in a transaction, revenue is recorded gross; otherwise, revenue is recorded on a net basis. The majority of the Company’s ancillary business revenue is recorded on a net basis. Commissions received from these service providers are considered variable consideration and are constrained until the third-party customer makes a purchase from one of the service providers.

Significant Judgments

Standalone Selling Prices—For arrangements that contain multiple performance obligations, the Company allocates the transaction price to each performance obligation on a relative standalone selling price basis.

Costs Incurred to Obtain a Contract—Incremental costs to obtain contracts are not material to the Company.

Policy Elections

In addition to those previously disclosed, the Company has made the following accounting policy elections and practical expedients:

Portfolio Approach—The Company uses the portfolio approach when multiple contracts or performance obligations are involved in the determination of revenue recognition.

Taxes—The Company excludes from the transaction price any taxes collected from customers that are remitted to taxing authorities.

Shipping and Handling Charges—Charges that are incurred before and after the customer obtains control of goods are deemed to be fulfillment costs.

Time Value of Money—The Company’s payment terms are less than one year from the transfer of goods. Therefore, the Company does not adjust promised amounts of consideration for the effects of the time value of money.

Disclosure of Remaining Performance Obligations—The Company does not disclose the aggregate amount of the transaction price allocated to remaining performance obligations for contracts that are one year or less in term. Additionally, the Company does not disclose the aggregate amount of the transaction price allocated to remaining performance obligations when the transaction price is allocated entirely to a wholly unsatisfied performance obligation or to a wholly unsatisfied promise to transfer a good or service that forms part of a series of distinct goods or services.

Disaggregation of Revenue

The Company’s club retail operations, which represent substantially all of the consolidated total revenues, are the Company’s only reportable segment. All of the Company’s identifiable assets are located in the United States. The Company does not have significant sales outside the United States, nor does any customer represent more than 10% of total revenues for any period presented. The following table summarizes the Company’s percentage of sales disaggregated by category for the thirteen and twenty-six weeks ended August 4, 2018:


Edible Grocery	23	%
Perishables	29	%

Related Party Transactions Management Agreement The Company had a management services agreement with the Sponsors for ongoing consulting and advisory services that terminated upon the consummation of the Company’s IPO. The management services agreement provided for the aggregate payment of management fees to the Sponsors (or advisory affiliates thereof) of $8.0 million per year, plus out of pocket expenses. The Company expensed $1.3 million and $2.0 million of management fees and out of pocket expenses for the thirteen weeks ended August 4, 2018 and July 29, 2017, respectively.

Management fees and expenses are reported in Selling, general and administrative expenses (“SG&A”) in the consolidated statements of operations and comprehensive income. One of the Company’s suppliers, Advantage Solutions Inc., is controlled by affiliates of the Sponsors. Advantage Solutions Inc. is principally a provider of in-club product demonstration and sampling services, and the Company also engages them from time to time to provide ancillary support services, including for example, seasonal gift wrapping, on-floor sales assistance and display maintenance. The Company incurred approximately $10.4 million and $7.9 million of costs payable to Advantage Solutions Inc. for services rendered during the thirteen weeks ended August 4, 2018 and July 29, 2017, respectively. The Company incurred approximately $21.4 million and $18.8 million of costs payable to Advantage Solutions Inc. for services rendered during the twenty-six weeks ended August 4, 2018 and July 29, 2017, respectively. The demonstration and sampling service fees are fully funded by merchandise vendors who participate in the program. The Company believes the terms obtained or consideration paid or received, as applicable, in connection with the transactions were comparable to terms available or amounts that would be paid or received, as applicable, in arm’s-length transactions with unrelated parties.

The ABL Facility is comprised of a $950.0 million revolving credit facility and a $50.0 million term loan. The ABL Facility is secured on a senior basis by certain “liquid assets” of the Company and secured on a junior basis by certain “fixed assets” of the Company. The $50.0 million term loan payment terms are restricted in that the term loan cannot be repaid unless all loans outstanding under the ABL Facility are repaid, and once repaid, cannot be re-borrowed. The availability under the $950.0 million revolving credit facility is restricted based on eligible monthly merchandise inventories and receivables as defined in the facility agreement. Interest rates under the revolving credit facility are calculated either on LIBOR plus a range of 150 to 200 basis points based on excess availability, or an alternative base rate calculation based on the higher of prime, the federal funds rate plus 50 basis points or one-month LIBOR plus 100 basis points, plus a range of 50 to 100 basis points based on excess availability.

Long-term portion		6,258							5,692

Total	$	8,271						$	7,705

The charges for BJ’s lease obligations are based on the present value of rent liabilities under the relevant leases, including estimated real estate taxes and common area maintenance charges, reduced by estimated income from the potential subleasing of these properties. Charges in both periods represent accretion expense on lease obligations.

On June 12, 2014, the Company entered into a sublease agreement for one of the clubs that pays a portion of BJ’s lease obligation through the end of the lease term. The rental income received from that sublease is included in the payments referenced in the tables above. During the second half of 2017, the Company experienced a lapse in the sublease rental income which resulted in the eviction of the current tenant. In January 2018, the Company entered into a new sublease agreement for the same property with a new tenant who will continue to pay a portion of the BJ’s lease obligation through the end of the lease term. The interruption of sublease income in the second half of 2017, and adjustment of future rental income from the new sublease agreement signed in January 2018, resulted in an additional charge of $0.7 million to the reserve. In addition, the Company lowered the estimated sublease income at the other existing closed location which resulted in an additional charge of $1.4 million to the reserve.

Contingently Redeemable Common Stock	Aug. 04, 2018
Text Block [Abstract]
Contingently Redeemable Common Stock	10. Contingently Redeemable Common Stock The Company and certain current and former management employees were party to the Management Stockholders Agreement (the “MSA”). All grants of equity by the Company to the employees were governed by the terms of individual equity award agreements and the MSA through the date of the Company’s IPO. The MSA specified certain transfer restrictions, tag-along and drag-along rights, put and call rights and various other rights and restrictions applicable to any equity held by employees. The call right permitted the Company to repurchase common stock held by an employee stockholder following a minimum holding period and prior to the expiration of a specified time period following the later of the employee’s termination of employment with the Company or acquisition of the common stock. If the employee’s employment was terminated for cause, the repurchase price was the least of (a) the fair market value as of the repurchase date, (b) the fair market value at issuance or (c) the price paid by the employee stockholder for such shares. If the employee’s employment was terminated other than for cause, the repurchase price was the fair market value as of the repurchase date. The MSA also gave the employees the ability to put any shares back to the Company at fair market value upon death or disability while actively employed. As neither death nor disability while actively employed was a certainty, the shares of common stock held by the employee stockholders were considered to be contingently redeemable common stock and were accounted for outside of stockholders’ equity until the shares of common stock were either repurchased by the Company or the put right terminated. The contingently redeemable common stock was recorded at fair value of the common stock as of the date of issuance. Because meeting the contingency was not probable, the contingently redeemable $10.4 million and $9.0 million of mezzanine equity was recorded on the Company’s consolidated balance sheet related to these agreements as of February 3, 2018 and July 29, 2017, respectively. Both the Company’s repurchase right, and the employee stockholder’s put right terminated upon the consummation of the Company’s IPO on June 28, 2018 and reclassified all contingently redeemable mezzanine equity to Common Stock on the Company’s consolidated balance sheet. As of August 4, 2018, there was no contingently redeemable Common Stock outstanding in the Company’s consolidated balance sheet. When the Company exercised its call option to repurchase shares classified outside of stockholders’ equity, it is deemed to be a constructive retirement of the contingently redeemable share for accounting purposes. The Company recorded the excess of the fair value paid to repurchase the share over the carrying value of the contingently redeemable share within additional paid-in capital, as the Company has an accumulated deficit.

Stock Incentive Plans

11. Stock Incentive Plans

On June 13, 2018, the Company’s Board of Directors adopted, and its stockholders approved, the 2018 Incentive Award Plan (the “2018 Plan”). The 2018 Plan provides for the grant of stock options, restricted stock, dividend equivalents, stock payments, restricted stock units, performance shares, other incentive awards, stock appreciation rights, and cash awards. Prior to the adoption of the 2018 Plan, the Company granted stock-based compensation to employees and non-employee directors, respectively, under the 2011 Plan and the 2012 Director Plan. No further grants will be made under 2011 Plan or the 2012 Director Plan.

The 2018 Plan authorizes the issuance of 13,148,058 shares, including 985,369 shares that were reserved but not issued under the 2011 Plan and the 2012 Director Plan. If an award under the 2018 Plan, 2011 Plan or 2012 Director Plan is forfeited, expires or is settled for cash, any shares subject to such award may, to the extent of such forfeiture, expiration or cash settlement, be used again for new grants under the 2018 Plan. Additionally, shares tendered or withheld to satisfy grant or exercise price, or tax withholding obligations associated with an award under the 2018 Plan, the 2011 Plan or the 2012 Director Plan will be added to the shares authorized for grant under the 2018 Plan. The following shares may not be used again for grant under the 2018 Plan: (1) shares subject to a stock appreciation right, that are not issued in connection with the stock settlement of the SAR on its exercise and (2) shares purchased on the open market with the cash proceeds from the exercise of options under the 2018 Plan, 2011 Plan or 2012 Director Plan.

The following table summarizes the Company’s stock award activity during the twenty-six weeks ended August 4, 2018 (shares in thousands):

Stock-based compensation expense was $51.2 million and $2.1 million for the thirteen weeks ended August 4, 2018 and July 29, 2017, respectively. Stock-based compensation expense was $52.1 million and $5.7 million for the twenty-six weeks ended August 4, 2018 and July 29, 2017, respectively.

In connection with the Company’s IPO, the Board of Directors granted the following new awards to certain employees under the 2018 Plan, subject to vesting: stock options to purchase 2,510 shares of common stock, with an exercise price of $17.00 and restricted stock in the amount of 2,943 shares with a grant date fair value of $22.00, equivalent to the closing price of the first day of trading.

Treasury Shares Acquired on Restricted Stock Awards

Upon the vesting of 1,954 restricted stock awards, 782 shares in this year’s first six months were reacquired to satisfy employees’ tax withholding obligations. These reacquired shares were recorded as $19.1 million of treasury stock and accordingly, reduced the number of common shares outstanding by 782 shares.

Income Tax Disclosure [Abstract]
Income Taxes	12. Income Taxes The effective income tax rate is based on estimated income from continuing operations for the year as well as discrete adjustments, if any, in the applicable quarterly periods. Potential discrete adjustments include tax charges or benefits related to stock based compensations, changes in tax legislation, settlements of tax audits and changes in uncertain tax positions, among others. The Company’s effective income tax rate from continuing operations was 73.7% and 36.0% for the thirteen weeks ended August 4, 2018 and July 29, 2017, respectively; and 682% and 36% for the twenty-six weeks ended August 4, 2018 and July 29, 2017, respectively. The change in the effective tax rate for the thirteen and twenty-six weeks ended August 4, 2018, is due to a reduction in the U.S. federal statutory tax rate from 35.0% to 21.0% as part of the U.S. Tax Cuts and Jobs Act (the “TCJA”) that was enacted in December 2017, and a stock option windfall tax benefit recorded in the current period. The Company projects the estimated annual effective tax rate for the year to be 27.2% excluding the tax effect of discrete events. As of August 4, 2018, no changes had been made to the previously recorded provisional amount of $32.1 million related to the re-measurement of the Company’s deferred tax balances in its consolidated financial statements for the year ended February 3, 2018 due to the TCJA. Any changes to the provisional amounts will be recorded in the period in which the adjustments are made. These changes could arise from additional analysis, changes in assumptions or interpretations the Company has made, additional guidance that may be issued and actions the Company may take as a result of the TCJA.

Discontinued Operations and Disposal Groups [Abstract]
Assets Held for Sale	16. Assets Held for Sale The Company’s club in Hooksett, New Hampshire was relocated to Manchester, New Hampshire in March 2018. The Company owns the land and building at the former Hooksett, New Hampshire location and is pursuing opportunities to sell this location. During the first quarter of 2018, the Company recorded an impairment loss of $3.0 million on the fixed assets of the Hooksett, New Hampshire location in order to lower the carrying value of the fixed assets to its estimated fair value less costs to sell. This charge is included within SG&A in the income statement. At August 4, 2018, the remaining value related to the club in Hooksett, New Hampshire that is recorded as assets held for sale on the balance sheet is $6.6 million. The value of assets held for sale is based on current market conditions, prices of similar assets in similar condition and expected proceeds from the sale of the assets, representative of Level 3 inputs on the fair value hierarchy.

As amended, First Lien Term Loan has an initial principal amount of $1.54 billion and an applicable rate of 3.00% for LIBOR loans. and 2.00% for base rate loans (in each case, with a 0.25% stepdown at first lien net leverage of 3.00 to 1.00), provided that until delivery of financial statements for the first full fiscal quarter ending after August 13, 2018, the applicable rate is 3.00% for LIBOR loans and 2.00% for base rate loans. The Company paid debt costs of $1.8 million and accrued interest of $1.2 million at closing. On August 15, 2018, the Company closed on the sale of the Hooksett, New Hampshire location and received proceeds of $6.6 million in exchange for all assets related to the club. The Company has no future obligations, outstanding liens or continuing involvement with this location. On August 17, 2018, the Company amended its ABL facility to extend the maturity date from February 3, 2022 to August 17, 2023 and to reduce the applicable interest rates and letter of credit fees on the facility. As amended, the applicable rate on revolving credit loans is LIBOR plus a range of 125 to 175 basis points or base rate plus a range of 25 to 75 basis points and the applicable rate on term loans is LIBOR plus a range of 200 to 250 basis points or base rate plus a range of 100 to 150 basis points, in all cases based on excess availability.

Accounting Policies [Abstract]

Basis of Presentation

Basis of Presentation

The accompanying interim financial statements of BJ’s Wholesale Club Holdings, Inc. are unaudited and, in the opinion of management, reflect all normal recurring adjustments considered necessary for a fair statement of the Company’s financial statements in accordance with generally accepted accounting principles in the United States of America. References to “BJ’s” or the “Company” refer to BJ’s Wholesale Club Holdings, Inc. and its consolidated subsidiaries, unless the context indicates otherwise.

The consolidated balance sheet as of February 3, 2018 is derived from the audited consolidated balance sheet as of that date. The unaudited results of operations for the quarter ended August 4, 2018 are not necessarily indicative of future results or results to be expected for the full year ending February 2, 2019. The Company’s business, in common with the business of retailers generally, is subject to seasonal influences. The Company’s sales and operating income have typically been highest in the fourth quarter holiday season and lowest in the first quarter of each fiscal year.

You should read these statements in conjunction with the Company’s audited consolidated financial statements and related notes starting in page F-1 of the Company’s final prospectus for its IPO filed pursuant to Rule 424(b)(4) under the Securities Act with the SEC on June 28, 2018 (the “Prospectus”).

Initial Public Offering

Initial Public Offering

On July 2, 2018, the Company completed its IPO, in which the Company issued and sold 43,125,000 shares of its common stock (including 5,625,000 shares of common stock that were subject to the underwriters’ option to purchase additional shares) at an initial public offering price of $17.00 per share. The Company received total aggregate proceeds of $685.9 million net of underwriters discounts, commissions and other transaction expenses, which totaled $47.2 million.

On July 2, 2018, the Company used the net proceeds from the IPO to extinguish the total outstanding balance of $623.3 million of its senior secured second lien term loan facility (the “Second Lien Term Loan”). See Note 6, Debt and Credit Arrangements footnote, for further discussion regarding the Second Lien Term Loan extinguishment.

Stock Split

Stock Split

On June 15, 2018, the Company effected a seven-to-one stock split of its issued and outstanding shares of common stock and proportional adjustment to the existing conversion ratios for each series of the Company’s Contingently Redeemable Common Stock (see Note 10). Accordingly, all shares and per share amounts for all periods presented in the accompanying consolidated financial statements and notes thereto have been adjusted retroactively, where applicable, to reflect this stock split and adjustment of the contingently redeemable common stock conversion ratios.

Deferred Offering Costs

Deferred Offering Costs

The Company capitalized certain legal, professional, accounting and other third-party fees that were directly associated with the IPO as deferred offering costs. Upon the consummation of the IPO, $47.2 million were recorded in stockholders’ deficit as a reduction of additional paid-in capital.

Recent Accounting Pronouncements

Recent Accounting Pronouncements

The accounting policies the Company follows are set forth in the Company’s audited financial statements for the fiscal year ended February 3, 2018 and included in the Company’s final Prospectus. There have been no material changes to these accounting policies, except as noted below for new accounting pronouncements adopted at the beginning of fiscal year 2018.

Revenue from Contracts with Customers (ASC No. 606)

In May 2014, the Financial Accounting Standards Board (“FASB”) issued ASU 2014-09, Revenue from Contracts with Customers (“ASC No. 606”), which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The ASU replaced most existing revenue recognition guidance in U.S. GAAP as of its effective date.

The Company adopted the new guidance at the beginning of fiscal year 2018 using the modified retrospective adoption method and recognized the cumulative effect of initially applying the new guidance as an adjustment to the opening balance of accumulated deficit. The new guidance was only applied to contracts not completed as of the initial date of application. Additionally, any contract that was modified prior to the adoption date has been reflected in the cumulative adjustment giving effect to the aggregate effect of all contract modifications prior to the initial application date. The impact of employing this practical expedient for contract modifications is immaterial. The comparative information has not been restated and continues to be reported under the accounting standards in effect for those periods. The cumulative effect of the changes made to the Company’s February 3, 2018 balance sheet for the adoption of the standard update was as follows (in thousands):


	Balance as of February 3, 2018			Adjustment for new Standard			Balance as of February 4, 2018
Prepaid expenses and other current assets	$	81,972		$	7,820		$	89,792
Accrued expenses and other current liabilities		495,767			16,645			512,412
Deferred income taxes		57,074			(2,463	)		54,611
Accumulated deficit		(1,036,012	)		(6,362	)		(1,042,374	)

The impact of the adoption of the standards update on the Company’s Consolidated Statement of Operations for the thirteen and twenty-six weeks ended August 4, 2018, resulted in a decrease to cost of sales and net sales of $1.1 million and $5.7 million, respectively, due to recording the allowance for returns reserve on a gross basis. The remaining impact of the adoption of the standards on the Company’s Consolidated Statement of Operations for the thirteen weeks and twenty-six weeks ended August 4, 2018 was immaterial.

The impact of the adoption of the standards update on the Company’s Consolidated Balance Sheet as of August 4, 2018 was as follows (in thousands):


	As of August 4, 2018,
	As Reported			Balance without adoption			Effect of change
Prepaid expenses and other current assets	$	69,116		$	62,270		$	6,846
Accrued expenses and other current liabilities		473,500			457,531			15,969
Deferred income taxes		52,988			55,586			(2,598	)
Accumulated deficit		(1,033,851	)		(1,027,325	)		(6,526	)

Classification of Costs Related to Defined Benefit Pension and Other Post-Retirement Benefit Plans (ASU 2017-07)

At the beginning of fiscal year 2018, the Company adopted ASU No. 2017-07, Compensation—Retirement Benefits (Topic 715: Improving the Presentation of Net Periodic Pension Cost and Net Periodic Post-Retirement Benefit Cost (“ASU 2017-07”). ASU 2017-07 changes how employers that sponsor defined benefit pension and/or other post-retirement benefit plans present the net periodic benefit costs in the statement of operations. Under this new guidance, an employer’s statement of operations presents service cost arising in the current period in the same statement line item as other employee compensation. However, all other components of current period costs related to defined benefit plans, such as prior service costs and actuarial gains and losses, are presented on the statement of operations on a line item outside (or below) operating income. ASU 2017-07 affects only the classification of certain costs on the statement of operations, not the determination of costs. Net periodic pension costs related to the Company’s frozen defined benefit pension plan and post-retirement medical benefit plan were not material for the second quarter of fiscal year 2018 or prior periods. The retrospective impacts of this standard on our historical financial statements are not material and will not be restated on future filings.

Modifications to Share-based Compensation Awards (ASU 2017-09)

At the beginning of fiscal year 2018, the Company adopted ASU No. 2017-09, Compensation-Stock Compensation Topic 718-Scope of Modification Accounting (“ASU 2017-09”). ASU 2017-09 clarifies when changes to the terms and conditions of share-based payment awards must be accounted for as modifications. Entities apply the modification accounting guidance if the value, vesting conditions, or classification of an award changes. The Company has not modified any share-based payment awards. Should the Company modify share-based payment awards in the future, it will apply the provisions of ASU 2017-09.

Definition of a Business (ASU 2017-01)

At the beginning of fiscal year 2018, the Company adopted ASU No. 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business (“ASU 2017-01”). ASU 2017-01 assists entities in determining if acquired assets constitute the acquisition of a business or the acquisition of assets for accounting and reporting purposes. This distinction is important because goodwill can only be recognized in an acquisition of a business. Prior to ASU 2017-01, if revenues were generated immediately before and after a transaction, the acquisition was typically considered a business. Under ASU 2017-01, entities are required to further assess the substance of the processes they acquire. Should the Company commence or complete an acquisition in future periods, it will apply the provisions of ASU 2017-01.

Statement of Cash Flows (ASU 2016-15)

At the beginning of fiscal year 2018, the Company adopted ASU No. 2016-15, Statement of Cash Flows (Topic 230) (“ASU 2016-15”). ASU 2016-15 represents a consensus of the FASB’s Emerging Issues Task Force on eight separate issues that, if present, can impact classifications on the statement of cash flows. The guidance requires application using a retrospective transition method. The adoption of ASU 2016-15 only impacted the classification of certain insurance proceeds on the Company consolidated statement of cash flows for the first quarter of fiscal year 2017. The Company’s insurance proceeds were $2.0 million for the second quarter of fiscal year 2018 and were not material for the second quarter of fiscal year 2017. The retrospective impacts of this standard on our historical financial statements are not material and will not be restated on future filings.

Recently Issued Accounting Pronouncements

In February 2016, the FASB issued ASU 2016-02, which requires lessees to recognize a right-of-use asset and a lease liability, initially measured at the present value of the lease payments for all leases with a term greater than 12 months. This standard is effective for annual reporting periods, and interim periods therein, beginning after December 15, 2018 and is required to be applied using a modified retrospective approach for all leases existing at, or entered into after, the beginning of the earliest comparative period presented. The Company has a significant number of leases, and as a result, expects this guidance to have a material impact on its Consolidated Balance Sheet, the impact of which is currently being evaluated.
