Summary of Significant Accounting Policies 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 ("GAAP").
The consolidated balance sheet as of February 1, 2020 is derived from the audited consolidated balance sheet as of that date. The unaudited results of operations for the first quarter of fiscal year 2020 are not necessarily indicative of future results or results to be expected for fiscal year 2020. 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.
These unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements and footnotes thereto included in our Annual Report on Form 10-K for the fiscal year 2019, as filed with the Securities and Exchange Commission (the "SEC") on March 19, 2020.
Reclassification
We adjusted the statement of cash flows for the first quarter of fiscal year 2020 to reclassify the change in book overdraft amounts into the accounts payable and accrued expenses line items, all within net cash provided by operating activities.    
Recently Adopted Accounting Pronouncements
The accounting policies the Company follows are set forth in its audited financial statements for fiscal year 2019. 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 2020.
Fair Value Measurement (ASU 2018-13)
In August 2018, the Financial Accounting Standards Board (the "FASB") issued Accounting Standards Update ("ASU") 2018-13 Changes to the Disclosure Requirements for Fair Value Measurement which updates the guidance to Fair Value Measurement (Topic 820). The updated guidance modifies the disclosure requirements for fair value measurements by removing, modifying or adding certain disclosures. The amendments on changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements, and the narrative description of measurement uncertainty should be applied prospectively for only the most recent interim or annual period presented in the initial fiscal year of adoption. All other amendments should be applied retrospectively to all periods presented upon their effective date. The Company adopted ASU 2018-13 at the beginning of fiscal year 2020 on a prospective basis and the adoption of this standard did not have a material impact on the Company's consolidated financial statements.
Intangibles-Goodwill and Other-Internal-Use Software (ASU 2018-15)

In August 2018, the FASB issued ASU 2018-15, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40). The update related to accounting for implementation costs incurred in a cloud computing arrangement that is a service contract. The update allows entities who are customers in hosting arrangements that are service contracts to apply the existing internal-use software guidance to determine which implementation costs to capitalize as an asset related to the service contract and which costs to expense. The update specifies classification for capitalizing implementation costs and related amortization expense within the financial statements and requires additional disclosures. The updated guidance is effective for fiscal reporting periods, including interim reporting within those periods, beginning after December 15, 2019. The Company adopted this standard at the beginning of fiscal year 2020 on a prospective basis. The adoption of this standard had no material impact on the Company's consolidated financial statements.

Goodwill Impairment (ASU 2017-04)
In January 2017, the FASB issued ASU 2017-04, which provides amendments to Accounting Standards Codification ("ASC") 350, Intangibles - Goodwill and Other, to eliminate Step 2 from the goodwill impairment test. Entities should perform their goodwill impairment tests by comparing the fair value of a reporting unit with its carrying amount and recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit's fair value. The Company adopted ASU 2017-04 at the beginning of fiscal year 2020 on a prospective basis and the adoption of this standard did not have a material impact on the Company's consolidated financial statements.
Credit Losses (ASU 2016-13)
In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (ASU 2016-13). This new guidance changes how entities account for credit impairment for trade and other receivables, as well as for certain financial assets and other instruments. ASU 2016-13 replaces the current "incurred loss" model with an "expected loss" model. Under the "incurred loss" model, a loss (or allowance) is recognized only when an event has occurred (such as a payment delinquency) that causes the entity to believe that a loss is probable (i.e., that it has been "incurred"). Under the "expected loss" model, an entity recognizes a loss (or allowance) upon initial recognition of the asset that reflects all future events that will lead to a loss being realized, regardless of whether it is probable that the future event will occur. The "incurred loss" model considers past events and current conditions, while the "expected loss" model includes expectations for the future which have yet to occur. The Company adopted ASU 2016-13 at the beginning of fiscal year 2020 and the adoption of this standard did not have a material impact on the Company's consolidated financial statements.
Recently Issued Accounting Pronouncements

Reference Rate Reform (ASU 2020-04)
In March 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848), which provides optional expedients and exceptions to the current guidance on contract modifications and hedging relationships to ease the financial reporting burdens of the expected market transition from LIBOR and other interbank offered rates to alternative reference rates. The guidance was effective upon issuance and may be applied prospectively to contract modifications made and hedging relationships entered into or evaluated on or before December 31, 2022. The Company is currently evaluating the impact of the new guidance on the Company's consolidated financial statements.
