Organization, Consolidation and Presentation of Financial Statements [Abstract]
Description of Business and Basis of Presentation	Description of Business and Basis of Presentation DICK’S Sporting Goods, Inc. (together with its subsidiaries, referred to as “the Company”, “we”, “us” and “our” unless specified otherwise) is a leading omni-channel sporting goods retailer offering an extensive assortment of authentic, high-quality sports equipment, apparel, footwear and accessories through a blend of dedicated teammates, in-store services and unique specialty shop-in-shops. The Company also owns and operates Golf Galaxy and Field & Stream specialty stores, as well as GameChanger, a youth sports mobile app for video streaming, scorekeeping, scheduling and communications. In addition, the Company offers its products through an eCommerce platform that is integrated with its store network, providing athletes with expertise as well as the convenience of a 24-hour storefront. When used in this Quarterly Report on Form 10-Q, unless the context otherwise requires or otherwise specifies, any reference to a “year” is to the Company’s fiscal year. Basis of Presentation and Use of Estimates The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with the requirements for Quarterly Reports on Form 10-Q and do not include all the disclosures normally required in annual consolidated financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). The interim consolidated financial statements are unaudited and have been prepared on the same basis as the annual audited consolidated financial statements. In the opinion of management, such unaudited consolidated financial statements include all adjustments (consisting only of normal recurring adjustments) necessary for a fair presentation of the interim financial information. The unaudited interim financial information should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended January 30, 2021 as filed with the Securities and Exchange Commission on March 24, 2021. Operating results for the 13 and 26 weeks ended July 31, 2021 are not necessarily indicative of the results that may be expected for the fiscal year ending January 29, 2022 or any other period. COVID-19 The pandemic caused by the coronavirus and its variants (“COVID-19”) continues to evolve. Its impact on the Company’s business remains uncertain and includes the longer-term economic recovery and what consumer discretionary spending behavior patterns may emerge when the pandemic subsides. COVID-19 has also caused disruptions and rising costs to global supply chains, and although the Company has successfully managed these challenges thus far, the Company’s ability to continue to replenish its inventory to meet continued levels of consumer demand could be impacted by further delays or disruptions. Accordingly, the Company currently cannot estimate the full impact that the COVID-19 pandemic may have on its financial condition and future results of operations, and it will continue to actively monitor its impact to the Company’s business. The Company continues to consider and assess the potential impact that the COVID-19 pandemic could have on its operations, as well as the assumptions and estimates used to prepare its financial statements such as inventory valuations, fair value measurements and potential asset impairment charges. Recently Adopted Accounting Pronouncements Income Taxes In December 2019, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2019-12, “Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes.” This update simplifies the accounting for income taxes by removing certain exceptions to the general principles in Accounting Standard Codification (“ASC”) 740 and also clarifies and amends existing guidance to improve consistent application. The Company adopted ASU 2019-12 during the first quarter of 2021. The adoption did not have a significant impact on the Company’s financial condition, results of operations, cash flows or disclosures. Recently Issued Accounting Pronouncements Reference Rate Reform In March 2020, the FASB issued ASU 2020-04, “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting.” The update provides optional guidance for a limited period of time to ease potential accounting impacts associated with transitioning away from reference rates that are expected to be discontinued, such as the London Interbank Offered Rate (“LIBOR”). The amendments in this ASU can be applied anytime between the first quarter of fiscal 2020 and the fourth quarter of fiscal 2022 and apply only to contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued. The impact of Topic 848 on the Company's financial statements and related disclosures is not expected to be significant. Convertible Instruments In August 2020, the FASB issued ASU 2020-06, “Debt - Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity’s Own Equity (Subtopic 815-40),” which simplifies the accounting for convertible debt instruments and convertible preferred stock by reducing the number of accounting models and the number of embedded conversion features that could be recognized separately from the primary contract. ASU 2020-06 also enhances transparency and improves disclosures for convertible instruments and earnings per share guidance. It is effective for annual reporting periods beginning after December 15, 2021, including interim periods within those fiscal years, and it permits the use of either the modified retrospective or fully retrospective method of transition. Early adoption is permitted, but no earlier than fiscal years beginning after December 15, 2020. The Company is currently evaluating the timing of adoption as well as the impact that the adoption of ASU 2020-06 will have on its financial statements, but it anticipates that adoption will result in a reduction in non-cash interest expense related to the Company’s convertible senior notes due 2025 (the “Convertible Senior Notes”).
