Summary of Significant Accounting Policies	Feb. 03, 2018
Accounting Policies [Abstract]
Summary of Significant Accounting Policies	1. Nature of Operations and Summary of Significant Accounting Policies The Company GameStop Corp. (“GameStop,” “we,” “us,” “our,” or the “Company”) is a global family of specialty retail brands that makes the most popular technologies affordable and simple. Within our family of brands, we are the world’s largest omnichannel video game retailer, the largest AT&T® (“AT&T”) authorized retailer, the largest Apple© (“Apple”) certified products reseller, and the owner of www.thinkgeek.com, one of the world’s largest sellers of collectible pop-culture themed products. As of February 3, 2018, GameStop's retail network and family of brands include 7,276 company-operated stores in the United States, Canada, Australia and Europe. We have five reportable segments, which are comprised of four geographic Video Game Brands segments—United States, Canada, Australia and Europe—and a Technology Brands segment. Our Technology Brands segment includes our Spring Mobile and Simply Mac businesses. Spring Mobile owns and operates our AT&T branded wireless retail stores. Our largest vendors in our Video Game Brands segments are Nintendo, Sony, Microsoft, Activision Blizzard and Electronic Arts, which accounted for 22%, 20%, 10%, 6% and 6%, respectively, of our new product purchases in fiscal year 2017; 10%, 24%, 14%, 6% and 7%, respectively, in fiscal year 2016; and 11%, 27%, 19%, 9% and 10%, respectively, in fiscal year 2015. Basis of Presentation and Consolidation Our consolidated financial statements include our accounts and the accounts of our wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. Our fiscal year is composed of the 52 or 53 weeks ending on the Saturday closest to the last day of January. Fiscal year 2017 consisted of the 53 weeks ended on February 3, 2018 ("fiscal 2017"). Fiscal year 2016 consisted of the 52 weeks ended on January 28, 2017 ("fiscal 2016"). Fiscal year 2015 consisted of the 52 weeks ended on January 30, 2016 ("fiscal 2015"). Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. In preparing these financial statements, we have made our best estimates and judgments of certain amounts included in the financial statements, giving due consideration to materiality. Changes in the estimates and assumptions used by us could have a significant impact on our financial results. Actual results could differ from those estimates. Cash and Cash Equivalents We consider all short-term, highly-liquid instruments purchased with an original maturity of three months or less to be cash equivalents. Our cash and cash equivalents are carried at cost, which approximates market value, and consist primarily of time deposits with highly rated commercial banks. From time to time depending upon interest rates, credit worthiness and other factors, we invest in money market investment funds holding direct U.S. Treasury obligations. Restricted Cash We consider bank deposits serving as collateral for bank guarantees issued on behalf of our foreign subsidiaries as restricted cash, which is included in other noncurrent assets in our consolidated balance sheets. Our restricted cash was $14.9 million and $10.2 million as of February 3, 2018 and January 28, 2017, respectively. Merchandise Inventories Our merchandise inventories are carried at the lower of cost or market generally using the average cost method. Under the average cost method, as new product is received from vendors, its current cost is added to the existing cost of product on-hand and this amount is re-averaged over the cumulative units. Pre-owned video game products traded in by customers are recorded as inventory at the amount of the store credit given to the customer. We are required to make adjustments to inventory to reflect potential obsolescence or over-valuation as a result of cost exceeding market. In valuing inventory, we consider quantities on hand, recent sales, potential price protections, returns to vendors and other factors. Our ability to assess these factors is dependent upon our ability to forecast customer demand and to provide a well-balanced merchandise assortment. Inventory is adjusted based on anticipated physical inventory losses or shrinkage and actual losses resulting from periodic physical inventory counts. Inventory reserves as of February 3, 2018 and January 28, 2017 were $59.2 million and $59.0 million, respectively. Property and Equipment Property and equipment are carried at cost less accumulated depreciation and amortization. Depreciation on furniture, fixtures and equipment is computed using the straight-line method over their estimated useful lives ranging from two to ten years. Maintenance and repairs are expensed as incurred, while betterments and major remodeling costs are capitalized. Leasehold improvements are capitalized and amortized over the shorter of their estimated useful lives or the terms of the respective leases, including option periods in which the exercise of the option is reasonably assured (generally ranging from two to ten years). Costs incurred in purchasing management information systems are capitalized and included in property and equipment. These costs are amortized over their estimated useful lives from the date the technology becomes operational. Our total depreciation expense was $138.4 million, $151.7 million and $144.9 million for fiscal 2017, 2016 and 2015, respectively. We periodically review our property and equipment when events or changes in circumstances indicate that its carrying amounts may not be recoverable or its depreciation or amortization periods should be accelerated. We assess recoverability based on several factors, including our intention with respect to our stores and those stores’ projected undiscounted cash flows. An impairment loss is recognized for the amount by which the carrying amount of the assets exceeds its fair value, determined based on an estimate of discounted future cash flows. We recorded impairment losses of $18.2 million, $19.4 million and $4.4 million in fiscal 2017, 2016 and 2015, respectively. See Note 2, "Asset Impairments," for further information regarding our asset impairment charges. Business Combinations Business combinations are accounted for under the acquisition method of accounting. Under this method, the assets acquired and liabilities assumed are recognized at their respective fair values as of the date of acquisition. The excess, if any, of the acquisition price over the fair values of the assets acquired and liabilities assumed is recorded as goodwill. For significant acquisitions, we utilize third-party appraisal firms to assist us in determining the fair values for certain assets acquired and liabilities assumed. Adjustments to the fair values of assets acquired and liabilities assumed are made until we obtain all relevant information regarding the facts and circumstances that existed as of the acquisition date, not to exceed one year from the date of the acquisition (the "measurement period"). Upon the conclusion of the measurement period, any subsequent adjustments are recorded to earnings. Costs associated with business acquisitions are expensed as incurred. Over the past several years, we have acquired certain AT&T authorized retailers and in 2015, we acquired Geeknet, Inc. an online and wholesale retailer of collectibles and other products. See Note 3, "Acquisitions and Divestitures" for additional information. Goodwill and Intangible Assets Goodwill represents the excess purchase price over tangible net assets and identifiable intangible assets acquired. Intangible assets are recorded apart from goodwill if they arise from a contractual right and are capable of being separated from the entity and sold, transferred, licensed, rented or exchanged individually. We are required to evaluate goodwill and other intangible assets not subject to amortization for impairment at least annually. This annual test is completed at the beginning of the fourth quarter of each fiscal year or when circumstances indicate the carrying value of the goodwill or other intangible assets might be impaired. Goodwill has been assigned to reporting units for the purpose of impairment testing. We have five operating segments, including Video Game Brands in the United States, Canada, Australia and Europe, and Technology Brands in the United States, which also define our reporting units based upon the similar economic characteristics of operations within each segment, including the nature of products, product distribution and the type of customer and separate management within these businesses. In order to test goodwill for impairment, we compare a reporting unit's carrying amount to its estimated fair value. If the reporting unit’s carrying value exceeds its estimated fair value, then an impairment charge is recorded in the amount of the excess. The estimated fair value of a reporting unit is determined based on its discounted cash flows, which are derived from our long-term financial forecasts. The discounted cash flows analysis requires significant assumptions including, among others, a discount rate and a terminal value. Goodwill impairment charges of $32.8 million were recognized in fiscal 2017. See Note 6, "Goodwill and Intangible Assets" for additional information. No goodwill impairment charges were recognized in fiscal 2016 and 2015. Our indefinite-lived intangible assets consist of dealer agreements and trade names. Intangible assets that are determined to have an indefinite life are not amortized, but are required to be evaluated at least annually for impairment. If the carrying value of an individual indefinite-lived intangible asset exceeds its fair value, such individual indefinite-lived intangible asset is impaired by the amount of the excess. The fair value of our dealer agreements are estimated using a discounted cash flow analysis known as the Greenfield Method, which assumes that a business, at its inception, owns only dealer agreements and must make capital expenditure, working capital and other investments to ramp up its operations to a level that is comparable to its current operations. The fair value of our trade names are estimated by using a relief-from-royalty approach, which assumes the value of the trade name is the discounted cash flows of the amount that would be paid by a hypothetical market participant had they not owned the trade name and instead licensed the trade name from another company. As a result of our fiscal 2017 and fiscal 2016 annual impairment testing, we recognized impairment charges totaling $339.8 million and $14.4 million, respectively, associated with our dealer agreements and trade names. See Note 6, "Goodwill and Intangible Assets" for additional information. No impairment charges associated with our indefinite-lived intangible assets were recognized in fiscal 2015. Our definite-lived intangible assets consist primarily of customer relationships, leasehold rights, advertising relationships and amounts attributed to favorable leasehold interests recorded as a result of business acquisitions. The estimated useful life and amortization methodology of intangible assets are determined based on the period in which they are expected to contribute directly to cash flows. Intangible assets that are determined to have a definite life are amortized over that period. Revenue Recognition We recognize revenue when the sales price is fixed or determinable, collection is reasonably assured and the customer takes possession of the merchandise, or in the case of commissions, when the commission-generating activity has been performed. Revenues do not include sales taxes or other taxes collected from customers. Revenue from the sales of our products is recognized at the time of sale, net of sales discounts and net of an estimated sales return reserve, based on historical return rates, with a corresponding reduction in cost of sales. Our sales return policy is generally limited to 30 days or less and as such our sales returns are, and historically have been, immaterial. The sales of pre-owned video game products are recorded at the retail price charged to the customer. Advertising revenues for Game Informer are recorded upon release of magazines for sale to consumers. Subscription revenues for our PowerUp Rewards loyalty program and magazines are recognized on a straight-line basis over the subscription period. Revenue from the sales of product replacement plans is recognized on a straight-line basis over the coverage period. Customer liabilities and other deferred revenues for our PowerUp Rewards loyalty program, gift cards, customer credits, magazines and product replacement plans are included in accrued liabilities (see Note 8, "Accrued Liabilities"). We also sell a variety of digital products which generally allow consumers to download software or play games on the internet. Certain of these products do not require us to purchase inventory or take physical possession of, or take title to, inventory. When purchasing these products from us, consumers pay a retail price and we earn a commission based on a percentage of the retail sale as negotiated with the product publisher. We recognize these commissions as revenue at the time of sale of these digital products. Our Spring Mobile business earns commission revenue as an AT&T authorized retailer related to the activation of new wireless customers, the activation of enhanced or upgraded features on existing wireless customer plans and certain other commission incentive opportunities that may be offered to us by AT&T. We have determined that we are not deemed the obligor on the underlying wireless services contracts that give rise to this commission revenue; therefore, commission revenue is recognized at the point at which the commission-generating activity has been performed, which is generally driven by customer activation. Commissions are recognized net of an allowance for chargebacks from AT&T for estimated customer cancellations, which is periodically assessed and adjusted to reflect historical cancellation experience. In May 2014, the Financial Accounting Standards Board ("FASB") issued a comprehensive update to current revenue accounting standards; see "—Recent Accounting Pronouncements" for additional information. Customer Liabilities We establish a liability upon the issuance of merchandise credits and the sale of gift cards. Revenue is subsequently recognized when the credits and gift cards are redeemed. In addition, breakage is recognized quarterly on unused customer liabilities older than two years to the extent that our management believes the likelihood of redemption by the customer is remote, based on historical redemption patterns. To the extent that future redemption patterns differ from those historically experienced, there will be variations in the recorded breakage. Breakage is recorded in cost of sales in our consolidated statements of operations. In May 2014, the FASB issued a comprehensive update to current revenue accounting standards; see "—Recent Accounting Pronouncements" for additional information. Vendor Arrangements We and most of our largest vendors participate in cooperative advertising programs and other vendor marketing programs in which the vendors provide us with cash consideration in exchange for marketing and advertising the vendors’ products. Our accounting for cooperative advertising arrangements and other vendor marketing programs results in a significant portion of the consideration received from our vendors reducing the product costs in inventory rather than as an offset to our marketing and advertising costs. The consideration serving as a reduction in inventory is recognized in cost of sales as inventory is sold. The amount of vendor allowances to be recorded as a reduction of inventory is determined based on the nature of the consideration received and the merchandise inventory to which the consideration relates. We apply a sell-through rate to determine the timing in which the consideration should be recognized in cost of sales. Consideration received that relates to video game products that have not yet been released to the public is deferred as a reduction of inventory. The cooperative advertising programs and other vendor marketing programs generally cover a period from a few days up to a few weeks and include items such as product catalog advertising, in-store display promotions, internet advertising, co-op print advertising and other programs. The allowance for each event is negotiated with the vendor and requires specific performance by us to be earned. Vendor allowances of $162.5 million, $184.3 million and $208.2 million were recorded as a reduction of cost of sales for fiscal 2017, 2016 and 2015, respectively. Loyalty Expenses Our PowerUp Rewards loyalty program allows enrolled members to earn points on purchases that can be redeemed for rewards that include discounts or merchandise. We estimate the net cost of the rewards that will be issued and redeemed and record this cost and the associated balance sheet liability as points are accumulated by loyalty program members. The two primary estimates utilized to record the balance sheet liability for loyalty points earned by members are the estimated redemption rate and the estimated weighted-average cost per point redeemed. We use historical redemption rates experienced under the loyalty program as a basis to estimate the ultimate redemption rate of points earned. The estimated weighted-average cost per point redeemed, used to estimate future redemption costs, is based on our most recent actual costs incurred to fulfill points that have been redeemed by our loyalty program members and is adjusted for recent changes in redemption costs, including the mix of rewards redeemed. We continually evaluate our methodology and assumptions based on developments in redemption patterns, cost per point redeemed and other factors. Changes in the ultimate redemption rate and weighted-average cost per point redeemed have the effect of either increasing or decreasing the liability through the current period provision by an amount estimated to cover the cost of all points previously earned but not yet redeemed by loyalty program members as of the end of the reporting period. The cost of free or discounted product is recognized in cost of sales and the associated liability is included in accrued liabilities. The reserve is released when loyalty program members redeem their respective points and the corresponding rewards are recorded to cost of goods sold in the period of redemption. The cost of administering the loyalty program, including program administration fees, program communications and cost of loyalty cards, is recognized in selling, general and administrative expenses. In May 2014, the FASB issued a comprehensive update to current revenue accounting standards, which will impact the accounting for our PowerUp Rewards loyalty program. See "—Recent Accounting Pronouncements" for additional information. Cost of Sales and Selling, General and Administrative Expenses Classification The classification of cost of sales and selling, general and administrative expenses varies across the retail industry. We include purchasing, receiving and distribution costs in selling, general and administrative expenses in the consolidated statements of operations. We include processing fees associated with purchases made by check and credit cards in cost of sales in the consolidated statements of operations. Advertising Expenses We expense advertising costs for television, newspapers and other media when the advertising takes place. Advertising expenses for fiscal 2017, 2016 and 2015 totaled $83.3 million, $76.6 million and $66.6 million, respectively. Income Taxes Income tax expense includes federal, state, local and international income taxes. Income taxes are accounted for utilizing an asset and liability approach and deferred tax assets and liabilities are recognized for the tax consequences of temporary differences between the financial reporting basis and the tax basis of existing assets and liabilities using enacted tax rates. Deferred tax assets and liabilities are measured using the enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the period that includes the enactment date. Valuation allowances are recorded to reduce deferred tax assets to the amount that will more likely than not be realized. We maintain liabilities for uncertain tax positions until examination of the tax year is completed by the applicable taxing authority, available review periods expire or additional facts and circumstances cause us to change our assessment of the appropriate accrual amount. See Note 7, "Income Taxes," for additional information. We plan on permanently reinvesting our undistributed foreign earnings outside the United States. Where foreign earnings are permanently reinvested, no provision for federal income or foreign withholding taxes is made. Should we have undistributed foreign earnings that are not permanently reinvested, United States income tax expense and foreign withholding taxes will be provided for at the time the earnings are generated. Leases We lease retail stores, warehouse facilities, office space and equipment. These assets and properties are generally leased under noncancelable agreements that expire at various dates through 2031 with various renewal options for additional periods. The agreements, which are classified as operating leases, generally provide for minimum and, in some cases, percentage rentals and require us to pay all insurance, taxes and other maintenance costs. Leases with step rent provisions, escalation clauses or other lease concessions are accounted for on a straight-line basis over the lease term, which includes renewal option periods when we are reasonably assured of exercising the renewal options and includes “rent holidays” (periods in which we are not obligated to pay rent). Cash or lease incentives received upon entering into certain store leases (“tenant improvement allowances”) are recognized on a straight-line basis as a reduction to rent expense over the lease term, which includes renewal option periods when we are reasonably assured of exercising the renewal options. We record the unamortized portion of tenant improvement allowances as a part of deferred rent. We do not have leases with capital improvement funding. Percentage rentals are based on sales performance in excess of specified minimums at various stores and are accounted for in the period in which the amount of percentage rentals can be accurately estimated. Foreign Currency Generally, we have determined that the functional currencies of our foreign subsidiaries are the subsidiaries’ local currencies. The assets and liabilities of the subsidiaries are translated at the applicable exchange rate as of the end of the balance sheet date and revenue and expenses are translated at an average rate over the period. Currency translation adjustments are recorded as a component of other comprehensive income. Net gains from foreign currency transactions and derivatives are included in selling, general and administrative expenses and were $2.4 million, $4.5 million and $1.6 million in fiscal 2017, 2016 and 2015, respectively. The foreign currency transaction gains and losses are primarily due to the decrease or increase in the value of the U.S. dollar compared to the functional currencies of the countries in which we operate internationally. We use forward exchange contracts, foreign currency options and cross-currency swaps (together, the “foreign currency contracts”) to manage currency risk primarily related to foreign-currency denominated intercompany assets and liabilities and certain other foreign currency assets and liabilities. These foreign currency contracts are not designated as hedges and, therefore, changes in the fair values of these derivatives are recognized in earnings, thereby offsetting the current earnings effect of the re-measurement of related intercompany loans and foreign currency assets and liabilities. See Note 4, "Fair Value Measurements and Financial Instruments," for additional information regarding our foreign currency contracts. Recently Adopted Accounting Pronouncements In January 2017, the FASB issued Accounting Standard Update ("ASU") 2017-04, Intangibles—Goodwill and Other, Simplifying the Test for Goodwill Impairment, which simplifies how an entity is required to test goodwill for impairment by eliminating Step 2 from the goodwill impairment test. Step 2 measures a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill and the carrying amount. Instead, entities will record an impairment charge based on the excess of a reporting unit's carrying amount over its estimated fair value. We early adopted this updated standard, effective January 29, 2017. In October 2016, the FASB issued ASU 2016-16, Accounting for Income Taxes: Intra-Entity Asset Transfers of Assets Other than Inventory, which eliminates the exception to defer the tax effects of intra-entity asset transfers (intercompany sales). Prior to this update, the tax effects of intra-entity asset transfers were deferred until the transferred asset was sold to a third party or otherwise recovered through use, which was an exception to the general requirement for comprehensive recognition of current and deferred income taxes. We early adopted this updated standard, effective January 29, 2017, and as a result we recognize tax expense or benefit from intercompany sales of assets other than inventory in the period in which the transaction occurs. In March 2016, the FASB issued ASU 2016-09, Improvements to Employee Share-Based Payment Accounting, which simplifies several aspects of accounting for employee share-based payment transactions. The amendments of the updated standard include, among other things, the requirement to recognize excess tax benefits and deficiencies through earnings and present the related cash flows in operating activities in the statement of cash flows, the election of a policy to either estimate forfeitures when determining periodic expense or recognize actual forfeitures when they occur, and an increase in the allowable income tax withholding from the minimum to maximum statutory rate and its classification in the statement of cash flows. As a result of the adoption of this updated standard, effective January 29, 2017, excess tax benefits and deficiencies are recognized in our results of operations and are presented in cash flows from operating activities in our statement of cash flows on a prospective basis. In addition, we elected to recognize actual forfeitures of stock-based awards as they occur. The adoption of this updated standard did not result in a material impact to our consolidated financial statements. Recent Accounting Pronouncements In August 2017, the FASB issued ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities. The new guidance is intended to more closely align hedge accounting with entities’ hedging strategies, simplify the application of hedge accounting and increase the transparency of hedging programs. The new guidance is effective for fiscal years beginning after December 15, 2018, with early adoption permitted. We do not anticipate that adoption of this standard will have a material impact to our consolidated financial statements. In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows, Classification of Certain Cash Receipts and Cash Payments, which provides guidance on eight specific cash flow issues in regard to how cash receipts and cash payments are presented and classified in the statement of cash flows. The updated standard is effective for fiscal years beginning after December 15, 2017, including interim periods within those years, with early adoption permitted. The amendments in the ASU should be adopted on a retrospective basis unless it is impracticable to apply, in which case the amendments should be applied prospectively as of the earliest date practicable. We are currently evaluating the impact that this standard will have on our consolidated financial statements and disclosures. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers, which sets forth a new five-step revenue recognition model that replaces the prior revenue recognition guidance in its entirety. The underlying principle of the new standard is that an entity will recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects what it expects in exchange for the goods or services. The updated standard also requires additional disclosures on the nature, timing, and uncertainty of revenue and related cash flows. In August 2015, the FASB issued ASU 2015-14, Revenue from Contracts with Customers: Deferral of the Effective Date, which delayed the effective date of ASU 2014-09 by one year to December 15, 2017 (with early adoption permitted). In 2016, the FASB issued several ASUs that further amended the new revenue standard in the areas of principal versus agent evaluation, licenses of intellectual property, identifying performance obligations, and other clarifications and technical corrections. Entities may use either a full retrospective or modified retrospective transition approach in applying these ASUs. The new revenue standard will primarily impact the accounting of our PowerUp Rewards loyalty program and the recognition of breakage associated with our gift cards liability. For our loyalty program, we currently estimate the net cost of the rewards that will be issued and redeemed and record this cost (presented as cost of sales) and the associated balance sheet liability as points are accumulated by our loyalty program members. Under the new standard, the transaction price will be allocated between the product(s) sold and loyalty points earned, where the portion allocated to the loyalty points will be initially recorded as deferred revenue and subsequently recognized as revenue upon redemption or expiration of the loyalty points. Estimated breakage on unused gift cards and merchandise credit liabilities is currently recognized on a quarterly basis (recorded to cost of sales) for balances older than two years to the extent that we believe the likelihood of redemption is remote. Under the new standard, we will recognize breakage in revenue based on and in proportion to historical redemption patterns, regardless of the age of the unused gift cards and merchandise credit liabilities. We will adopt the new standard in the first quarter of fiscal 2018, using the modified-retrospective transition approach. Under this approach, we will apply the new revenue standard on a prospective basis, effective February 4, 2018, and record adjustments to our fiscal 2018 opening balance sheet (as of February 4, 2018) to reflect the cumulative effect of the new revenue standard. We will also provide quantitative and qualitative disclosures of the new standard’s impact to each of our financial statement line items during fiscal 2018. The cumulative-effect adjustment will include a reduction of our gift card and customer deposit liabilities of approximately $46 million, an increase to our loyalty program liabilities of approximately $28 million and a net increase to our retained earnings of approximately $18 million (approximately $12 million, net of tax). In addition, the adoption of the new standard will result in expanded revenue recognition disclosures. We do not expect the adoption of the new revenue standard to have a material impact to our consolidated statements of operations or statements of cash flows. In February 2016, the FASB issued ASU 2016-02, Leases. The standard requires a lessee to recognize a liability related to lease payments and an offsetting right-of-use asset representing a right to use the underlying asset for the lease term on the balance sheet. Entities are required to use a modified retrospective transition approach for leases that exist or are entered into after the beginning of the earliest comparative period presented in the financial statements, with certain reliefs available. The ASU is effective for fiscal years, and interim periods within those years, beginning after December 15, 2018, with early adoption permitted. We are currently evaluating the overall impact to our consolidated financial statements, though we expect the adoption to result in a material increase in the assets and liabilities reflected in our consolidated balance sheets.

Acquisitions

3. Acquisitions and Divestitures

Fiscal 2017

Disposition of Kongregate

On July 21, 2017, we sold our ownership interest in Kongregate, a web and mobile gaming platform and publisher of mobile games, for proceeds of $54.7 million, net of transaction costs, of which $3.5 million was restricted cash held in escrow primarily for indemnification purposes. We recognized a gain on the sale of $6.4 million, net of tax, which is classified in selling, general and administrative expenses in our consolidated statements of operations for fiscal 2017. The disposed net assets of Kongregate primarily consisted of goodwill.

Disposition of Cricket Wireless

On January 24, 2018, we sold 63 Cricket Wireless branded stores for proceeds of $3.8 million. The gain on the sale was not material to our results of operations for fiscal 2017. We had no remaining Cricket Wireless stores as of February 3, 2018.

Fiscal 2016

Acquisition of Cellular World & Red Skye Wireless

In August 2016, Spring Mobile completed the acquisition of certain assets comprised of 436 stores from two authorized AT&T retailers, Cellular World and Red Skye Wireless. The purchase price consisted of $393.3 million in cash (net of $0.1 million of cash acquired), which included the effect of working capital adjustments, and future contingent consideration. The cash portion of the purchase price was funded with proceeds from our $475.0 million unsecured senior notes due in March 2021 combined with a draw on our revolving credit facility.

We recognized an acquisition-date liability of $43.2 million representing the total estimated fair value of the contingent consideration; see Note 4, "Fair Value Measurements and Financial Instruments," for additional information.

The estimated purchase price of the acquisition totaled $436.5 million, which includes the cash payment of $393.3 million plus the fair value of the contingent consideration of $43.2 million. The following table summarizes the estimated fair values of the assets acquired and liabilities assumed as of the acquisition date (in millions):



Assets acquired
Merchandise inventories	$	13.1
Prepaid expenses and other current assets	0.2
Property and equipment	23.9
Goodwill	239.1
Other intangible asset — dealer agreements	163.0
Other noncurrent assets	6.9
Total assets acquired	446.2
Liabilities assumed
Accounts payable	9.5
Accrued liabilities	0.2
Total liabilities assumed	9.7

Total estimated purchase price	$	436.5

The goodwill recognized reflects the acquired assembled workforce and Spring Mobile's entrance into new domestic regional markets. The goodwill recognized is assigned to the Technology Brands segment and is deductible for tax purposes. The intangible asset recognized for dealer agreements represents the value associated with the exclusive agreements with AT&T to operate the acquired stores. The intangible asset for dealer agreements is indefinite lived and not subject to amortization, but is subject to annual impairment testing.

Subsequent to the acquisition date, the stores acquired from Cellular World and Red Skye Wireless contributed $136.6 million in net sales in fiscal 2016. Pro forma information cannot be presented due to the impracticability of obtaining separately identifiable historical financial data for the acquired stores.

Acquisition of Midwest Cellular

In May 2016, in connection with the expansion of our Technology Brands segment, Spring Mobile completed the acquisition of certain assets of an AT&T authorized retailer, Midwest Cellular, comprised of 71 stores for cash consideration of $47.0 million. The acquisition was funded with proceeds from our $475.0 million unsecured senior notes due in March 2021. We recorded $42.7 million of indefinite-lived intangible assets related to this acquisition. The pro forma effect of this acquisition is not material to our consolidated financial statements.

Fiscal 2015

Acquisition of Geeknet, Inc.

In July 2015, we purchased Geeknet, Inc. ("Geeknet") an online and wholesale retailer that sells collectibles, apparel, gadgets, electronics, toys and other retail products for technology enthusiasts and general consumers under the name ThinkGeek through the www.thinkgeek.com website and certain exclusive products to wholesale channel customers. The addition of Geeknet provided an expansion of our global omnichannel platform and enabled us to broaden our product offering in the collectibles category and deepen relationships with our existing customer base.

Total consideration was $126.0 million, net of $13.9 million of cash acquired. The following table summarizes the estimated fair values of the assets acquired and liabilities assumed as of the acquisition date (in millions):



Assets acquired
Receivables	$	6.9
Merchandise inventories	25.6
Prepaid expenses and other current assets	12.5
Property and equipment	0.9
Deferred income taxes	2.8
Other non-current assets	0.1
Goodwill	52.2
Other intangible assets	33.4
Total assets acquired	134.4

Accounts payable	3.6
Accrued liabilities	17.3
Deferred income taxes	(12.6		)
Other long-term liabilities	0.1
Total liabilities assumed	8.4

Total purchase price	$	126.0

The goodwill of $52.2 million resulting from the acquisition is not deductible for tax purposes and represents the value we paid for the knowledge and expertise of, and established presence in, the collectibles market. The operating results of Geeknet have been included in our consolidated financial statements beginning on the closing date of July 17, 2015 and are reported in our United States Video Game Brands segment. The pro forma effect assuming this acquisition was made at the beginning of the earliest period presented herein is not material to our consolidated financial statements.

Acquisitions in Technology Brands

In fiscal 2015, Spring Mobile completed acquisitions of certain AT&T authorized retailers and Simply Mac completed an acquisition of an authorized Apple retailer for a total combined consideration of $141.5 million (net of cash acquired). We recorded $46.3 million of goodwill and $76.6 million of other intangible assets related to these acquisitions. The operating results of these acquisitions are included in our consolidated financial statements beginning on the respective closing dates of each acquisition and are reported in our Technology Brands segment. The pro forma effect assuming these acquisitions were made at the beginning of the earliest period presented herein is not material to our consolidated financial statements.

Fair Value Disclosures [Abstract]

Fair Value Measurements and Financial Instruments

4. Fair Value Measurements and Financial Instruments

Fair value is defined as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Applicable accounting standards require disclosures that categorize assets and liabilities measured at fair value into one of three different levels depending on the observability of the inputs employed in the measurement. Level 1 inputs are quoted prices in active markets for identical assets or liabilities. Level 2 inputs are observable inputs other than quoted prices included within Level 1 for the asset or liability, either directly or indirectly through market-corroborated inputs. Level 3 inputs are unobservable inputs for the asset or liability reflecting our assumptions about pricing by market participants.

Assets and Liabilities that are Measured at Fair Value on a Recurring Basis

Assets and liabilities that are measured at fair value on a recurring basis include our foreign currency contracts, life insurance policies we own that have a cash surrender value, contingent consideration payable associated with acquisitions, and certain nonqualified deferred compensation liabilities.

We value our foreign currency contracts, our life insurance policies with cash surrender values and certain nonqualified deferred compensation liabilities based on Level 2 inputs using quotations provided by major market news services, such as Bloomberg, and industry-standard models that consider various assumptions, including quoted forward prices, time value, volatility factors, and contractual prices for the underlying instruments, as well as other relevant economic measures, all of which are observable in active markets. When appropriate, valuations are adjusted to reflect credit considerations, generally based on available market evidence.

In August 2016, we acquired certain assets from Cellular World and Red Skye Wireless (see Note 3, "Acquisitions and Divestitures"). The purchase price included two contingent payments with an acquisition-date liability of $43.2 million representing the total estimated fair value of the contingent consideration. The first payment of $20.0 million was contingent on the relocation of certain stores and was paid in August 2017. The second payment was variable and contingent on the sales performance of certain acquired stores during calendar year 2017. Based on the actual sales performance of these stores, we recognized an $11.0 million adjustment to reduce the contingent liability to $12.2 million during fiscal 2017, which was paid in the first quarter of fiscal 2018. The fair value was estimated based on Level 3 inputs which include future sales projections derived from our historical experience with comparable acquired stores and a discount rate commensurate with the risks and inherent uncertainty in the business.

The following table provides the fair value of our assets and liabilities measured on a recurring basis and recorded on our consolidated balance sheets (in millions):



	February 3, 2018				January 28, 2017
	Level 2		Level 3		Level 2		Level 3

___________________

(1) Recognized in other non-current assets in our consolidated balance sheets.

(2) Recognized in accrued liabilities in our consolidated balance sheets.


(3)	As of February 3, 2018, $12.2 million was included in accrued liabilities in our consolidated balance sheets. As of January 28, 2017, the current portion of $20.0 million was recognized in accrued liabilities and the noncurrent portion of $23.2 million was recognized in other long-term liabilities in our consolidated balance sheet.

We use forward exchange contracts, foreign currency options and cross-currency swaps (together, the “foreign currency contracts”) to manage currency risk primarily related to intercompany loans denominated in non-functional currencies and certain foreign currency assets and liabilities. These foreign currency contracts are not designated as hedges and, therefore, changes in the fair values of these derivatives are recognized in earnings, thereby offsetting the current earnings effect of the re-measurement of related intercompany loans and foreign currency assets and liabilities. The total gross notional value of derivatives related to our foreign currency contracts was $563.3 million and $586.0 million as of February 3, 2018 and January 28, 2017, respectively.

Activity related to the trading of derivative instruments and the offsetting impact of related intercompany and foreign currency assets and liabilities recognized in selling, general and administrative expense is as follows (in millions):



	Fiscal Year
	2017			2016			2015
(Losses) gains on the changes in fair value of derivative instruments	$	(24.6	)	$	20.0		$	(5.2	)
Gains (losses) on the re-measurement of related intercompany loans and foreign currency assets and liabilities	27.0			(15.5		)	6.8
Total	$	2.4		$	4.5		$	1.6

We do not use derivative financial instruments for trading or speculative purposes. We are exposed to counterparty credit risk on all of our derivative financial instruments and cash equivalent investments. We manage counterparty risk according to the guidelines and controls established under comprehensive risk management and investment policies. We continuously monitor our counterparty credit risk and utilize a number of different counterparties to minimize our exposure to potential defaults. We do not require collateral under derivative or investment agreements.

Assets that are Measured at Fair Value on a Nonrecurring Basis

Assets that are measured at fair value on a nonrecurring basis relate primarily to property and equipment and other intangible assets, which are remeasured when the estimated fair value is below its carrying value. For these assets, we do not periodically adjust carrying value to fair value; rather, when we determine that impairment has occurred, the carrying value of the asset is reduced to its fair value.

In fiscal 2017, we recognized impairment charges of $328.8 million and $11.0 million associated with our Spring Mobile AT&T dealer agreements and Simply Mac Apple dealer agreements, respectively, to reflect their fair values of $77.0 million and zero, respectively. In fiscal 2016, we recognized impairment charges of $7.0 million associated with our Simply Mac Apple dealer agreement to reflect its fair value of $11.0 million.

In fiscal 2016, we recognized impairment charges of $7.4 million, associated with our Micromania trade name, to reflect its fair value of $35.0 million.

In fiscal 2017, 2016 and 2015, we recognized impairment charges of $18.2 million, $19.4 million and $4.4 million, respectively, primarily associated store-level property and equipment, to reflect their fair values of zero.

The fair value estimates of the dealer agreements, trade names and store-level property and equipment are based on significant unobservable inputs (Level 3) developed using company-specific information. These assets were valued using variations of the discounted cash flow method, which require assumptions associated with, among others, projected sales and cost estimates, capital expenditures, royalty rates, discount rates, terminal values and remaining useful lives. See Note 1, "Nature of Operations and Summary of Significant Accounting Policies," for further information related to our valuation methods.

Other Fair Value Disclosures

The carrying values of our cash equivalents, receivables, net, accounts payable and notes payable approximate the fair value due to their short-term maturities.

As of February 3, 2018, our unsecured 5.50% senior notes due in 2019 had a net carrying value of $347.9 million and a fair value of $356.0 million, and our unsecured 6.75% senior notes due in 2021 had a net carrying value of $470.0 million and a fair value of $495.7 million. The fair values of our senior notes were determined based on quoted market prices obtained through an external pricing source which derives its price valuations from daily marketplace transactions, with adjustments to reflect the spreads of benchmark bonds, credit risk and certain other variables. We have determined this to be a Level 2 measurement as all significant inputs into the quote provided by our pricing source are observable in active markets.

On an annual basis, we perform an impairment test of goodwill during the fourth quarter (see Note 1, "Nature of Operations and Summary of Significant Accounting Policies"). As a result of the fiscal 2017 annual impairment test, we determined that the carrying amount of our Technology Brands business exceeded its fair value and recognized a goodwill impairment charge of $32.8 million. The impairment was the result of a decline in the projected profitability and store count growth in our Technology Brands business, primarily associated with Spring Mobile. The lower projected profitability is due to the negative impact of a longer upgrade cycle for new mobile devices and changes made by AT&T to the compensation structure in 2017. While Technology Brands remains profitable, we currently do not expect to invest and grow the store count at the levels in previous long-term financial forecasts. No goodwill impairment charges were recognized in fiscal 2016 and 2015. Cumulative goodwill impairment charges were $673.3 million as of February 3, 2018, of which $13.5 million, $100.3 million, $107.1 million, $419.6 million and $32.8 million were attributable to our United States, Canada, Australia, Europe and Technology Brands segments, respectively.

___________________


(1)	The change in the gross carrying amount of intangible assets from January 28, 2017 to February 3, 2018 is due to impairments (see Note 2, "Asset Impairments") and the impact of exchange rate fluctuations.

Indefinite-lived Intangible Assets

Our trade names consist of Micromania, our video game business in France, which we acquired in 2008; and ThinkGeek, our online and wholesale collectibles retailer, which we acquired in 2015.

Dealer agreements are associated with our Spring Mobile and Simply Mac businesses within our Technology Brands segment. Spring Mobile maintains exclusive agreements with AT&T to operate AT&T branded stores as an “Authorized Retailer” and Simply Mac maintains exclusive agreements with Apple to sell their products in Simply Mac branded stores. The dealer agreements carrying amount included in our consolidated balance sheets represents the value associated with the rights and privileges afforded to us under these agreements.

Indefinite-lived intangible assets are expected to contribute to cash flows indefinitely and, therefore, are not subject to amortization but are subject to annual impairment testing. We test our indefinite-lived intangible assets during the fourth quarter (see Note 1, "Nature of Operations and Summary of Significant Accounting Policies"). As a result of our fiscal 2017 annual impairment testing, we recognized impairment charges totaling $339.8 million associated with our dealer agreements.

The dealer agreement impairment charges included $328.8 million for Spring Mobile and $11.0 million for Simply Mac. The impairment of Spring Mobile’s AT&T dealer agreements was the result of the decline in projected profitability in our long-term financial forecasts as described above in “—Goodwill.” The impairment of Simply Mac’s Apple dealer agreements was the result of recent and projected financial performance no longer supporting its carrying value.

Finite-lived Intangible Assets

Leasehold rights, the majority of which were recorded as a result of the purchase of SFMI Micromania SAS (“Micromania”) in 2008, represent the value of rights of tenancy under commercial property leases for properties located in France. Rights pertaining to individual leases can be sold by us to a new tenant or recovered by us from the landlord if the exercise of the automatic right of renewal is refused. Leasehold rights are amortized on a straight-line basis over the expected lease term, not to exceed 20 years, with no residual value.

Customer relationships, which were recorded as a result of the ThinkGeek acquisition, represent the value of the relationships related to both wholesale and website customers within the United States. ThinkGeek sells its products directly to large wholesale retailers and also sells its products directly to customers on its ThinkGeek website. Wholesale customer relationships are amortized on a straight-line basis over seven years, and website customer relationships are amortized on a straight-line basis over five years.

Other intangible assets include design portfolio and favorable leasehold interests. The design portfolio reflects the collection of product designs and ideas that were created by Geeknet and recorded as a result of the Geeknet acquisition. These designs are amortized on a straight-line basis over three years. Favorable leasehold interests represent the value of the contractual monthly rental payments that are less than the current market rent at stores acquired as part of the Micromania acquisition. Favorable leasehold interests are amortized on a straight-line basis over their remaining lease term with no expected residual value.

As of February 3, 2018, the total weighted-average amortization period for our finite-lived intangible assets was approximately 9.4 years. The intangible assets are being amortized based upon the pattern in which the economic benefits of the intangible assets are being utilized, with no expected residual value.

Intangible asset amortization expense during fiscal 2017, 2016 and 2015 was $13.4 million, $15.0 million and $13.4 million, respectively. The estimated aggregate intangible asset amortization expense for the next five fiscal years is as follows (in millions):



Fiscal Year Ending on or around January 31,	Projected Amortization Expense
2019	$	11.4
2020	8.7
2021	6.4
2022	4.5

(1)	Per IRC Section 15, we have incorporated a blended rate of 33.7% for our year end current provision ending February 3, 2018.

(2)

In fiscal 2016, we adopted a plan of reorganization specific to certain foreign operations which resulted in our ability to recognize the benefit of foreign net operating loss carryforwards that were previously unrecognized in affected jurisdictions. As a result, we recognized a tax benefit of $42.1 million in the fourth quarter of fiscal 2016, which is subject to a partial valuation allowance of $14.8 million. The valuation allowance established for this tax benefit is reflected in the line item “Change in valuation allowance.”


(3)	Other is comprised of numerous items, none of which is greater than 1.69% of earnings before income taxes.

On December 22, 2017, H.R. 1, formerly known as the Tax Cuts and Jobs Act of 2017 (the “Tax Act”), was signed into law. The Tax Act makes broad and complex changes to the Internal Revenue Code, including, but not limited to: (i) reducing the future U.S. federal corporate tax rate from 35 percent to 21 percent; (ii) requiring companies to pay a one-time transition tax on certain unremitted earnings of foreign subsidiaries; and (iii) providing for bonus depreciation that will allow full expensing of certain qualified property.

The Tax Act also established new tax laws that will come into effect beginning in 2018, including, but not limited to: (i) the reduction of the U.S. federal corporate tax rate discussed above; (ii) a general elimination of U.S. federal income taxes on dividends from certain foreign subsidiaries; (iii) a new provision designed to tax global intangible low-taxed income (“GILTI”); (iv) the repeal of the domestic production activity deductions; (v) limitations on the deductibility of certain executive compensation; (vi) limitations on the use of certain foreign tax credits to reduce the U.S. income tax liability; and (vii) a new provision that allows a domestic corporation an immediate deduction for a portion of its foreign derived intangible income (“FDII”).

Further, the Securities and Exchange Commission staff issued Staff Accounting Bulletin (“SAB”) 118, which provides guidance on accounting for the immediate tax effects of the Tax Act. SAB 118 provides a measurement period that should not extend beyond one year from the Tax Act enactment date for companies to complete the related accounting under ASC 740, Accounting for Income Taxes. In accordance with SAB 118, a company must reflect the income tax effects of those aspects of the Tax Act for which the accounting under ASC 740 is complete. To the extent that a company’s accounting for a certain income tax effect of the Tax Act is incomplete, but it is able to determine a reasonable estimate, it must record a provisional estimate in the financial statements. If a company cannot determine a provisional estimate to be included in the financial statements, it should continue to apply ASC 740 on the basis of the provisions of the tax laws that were in effect immediately before the enactment of the Tax Act.

Our accounting for certain elements of the Tax Act is incomplete. However, we were able to make reasonable estimates of the effects and, therefore, recorded provisional estimates for these items. In connection with our initial analysis of the impact of the Tax Act, we have recorded a provisional net tax expense of $42.0 million in the period ended February 3, 2018. This provisional estimate consists of a net expense of $10.2 million for the one-time transition tax resulting from the recognition of approximately $333.4 million of foreign earnings and profits, and a net expense of $31.8 million related to revaluation of deferred tax assets and liabilities, caused by the new lower corporate tax rate.

To determine the transition tax, we must determine the amount of post-1986 accumulated earnings and profits of its relevant subsidiaries as of certain prescribed measurement dates, as well as the amount of non-U.S. income taxes paid on such earnings. While we were able to make a reasonable estimate of the transition tax based on the guidance issued as of the date of these financial statements, we are continuing to gather additional information, and expect additional guidance from the Treasury and IRS, to be able to more precisely compute the final amount.

Likewise, while we were able to make a reasonable estimate of the impact of the reduction to the corporate tax rate, we may be affected by other analyses related to the Tax Act. These include, but are not limited to, the state tax effect of adjustments made to federal temporary differences.

Due to the complexity of the new GILTI tax rules, we are continuing to evaluate this provision of the Tax Act and the application of ASC 740. Under GAAP, we are allowed to make an accounting policy choice to either: (1) treat taxes due on future U.S. inclusions in taxable income related to GILTI as a current-period expense when incurred (the “period cost method”); or (2) factor in such amounts into our measurement of our deferred taxes (the “deferred method”). Our selection of an accounting policy with respect to the new GILTI tax rules is dependent on additional analysis and potential future modifications to our existing legal structure, which are not currently known. Accordingly, we have not made any adjustments related to potential GILTI tax in our financial statements and have not made a policy decision regarding whether to record deferred taxes on GILTI.

We will continue to analyze the full effects of the Tax Act on the financial statements. The impact of the Tax Act may differ from the current estimate, possibly materially, due to changes in interpretations and assumptions we have made, future guidance that may be issued and actions we may take as a result of the law.

Differences between financial accounting principles and tax laws cause differences between the bases of certain assets and liabilities for financial reporting purposes and tax purposes. The tax effects of these differences, to the extent they are temporary, are recorded as deferred tax assets and liabilities which are presented in the table below (in millions). Certain prior year balances have been reclassified to conform to current year presentation.

The above amounts are reflected in the consolidated financial statements as:

Deferred income taxes - liabilities	$	(5.0	)	$	(23.0	)

We file income tax returns in the U.S. federal jurisdiction and various states and foreign jurisdictions. The Internal Revenue Service (“IRS”) is currently examining our U.S. income tax returns for the fiscal years 2010 through 2016. We do not anticipate any adjustments that would result in a material impact on our consolidated financial statements as a result of these audits. We are no longer subject to U.S. federal income tax examination for years before and including the fiscal year ended January 30, 2010.

With respect to state and local jurisdictions and countries outside of the United States, we and our subsidiaries are typically subject to examination for three to six years after the income tax returns have been filed. Although the outcome of tax audits is always uncertain, we believe that adequate amounts of tax, interest and penalties have been provided for in the accompanying consolidated financial statements for any adjustments that might be incurred due to state, local or foreign audits.

As of February 3, 2018, we have approximately $25.3 million of net operating loss ("NOL") carryforwards in various foreign jurisdictions that expire in years 2018 through 2035, as well as $246.1 million of foreign NOL carryforwards that have no expiration date. In addition, the Company has approximately $0.9 million of foreign tax credit carryforwards that expire in years 2022 through 2026. The Company also has approximately $74.2 million of Federal NOL carryovers acquired through the ThinkGeek acquisition that will expire in years 2020 through 2035.

As of February 3, 2018, the gross amount of unrecognized tax benefits was approximately $24.9 million. If we were to prevail on all uncertain tax positions, the net effect would be a benefit to our effective tax rate of $18.8 million, exclusive of any benefits related to interest and penalties. A reconciliation of the changes in the gross balances of unrecognized tax benefits follows (in millions):



	Fiscal Year
	2017			2016			2015
Beginning balance of unrecognized tax benefits	$	42.1		$	31.9		$	21.4
Increases related to current period tax positions	1.0			3.5			4.0
Increases related to prior period tax positions	11.2			7.9			9.0
Reductions as a result of a lapse of the applicable statute of limitations	(1.3		)	(0.2		)	(1.0		)
Reductions as a result of settlements with taxing authorities	(28.1		)	(1.0		)	(1.5		)
Ending balance of unrecognized tax benefits	$	24.9		$	42.1		$	31.9

We recognize accrued interest and penalties related to unrecognized tax benefits in income tax expense. As of February 3, 2018, January 28, 2017 and January 30, 2016, we had approximately $6.9 million, $7.2 million and $4.9 million, respectively, in interest and penalties related to unrecognized tax benefits accrued, of which approximately $0.3 million, $2.3 million and $0.4 million of expense were recognized through income tax expense in fiscal 2017, 2016 and 2015. If we were to prevail on all uncertain tax positions, the reversal of these accruals related to interest would also be a benefit to our effective tax rate.

It is reasonably possible that the amount of the unrecognized benefit with respect to certain of our unrecognized tax positions could significantly increase or decrease within the next 12 months as a result of settling ongoing audits. However, as audit outcomes and the timing of audit resolutions are subject to significant uncertainty, and given the nature and complexity of the issues involved, we are unable to reasonably estimate the possible amount of change in the unrecognized tax benefits, if any, that may occur within the next 12 months as a result of ongoing examinations. Nevertheless, we believe we are adequately reserved for our uncertain tax positions as of February 3, 2018.

Deferred income taxes have not been provided for on any undistributed and untaxed earnings generated by certain foreign subsidiaries as of February 3, 2018 because we intend to permanently reinvest such earnings outside the United States. We do not currently require, nor do we have plans for, the repatriation of retained earnings from these subsidiaries. However, in the future, if we determine to repatriate these funds, or we sell or liquidate any of these subsidiaries, we may be required to provide for certain income taxes on the repatriation. We may also be required to withhold foreign taxes depending on the foreign jurisdiction from which the funds are repatriated. As noted above, taking into account the time line provided in SAB 118, we continue to analyze the full effects of the Tax Act on the financial statements and will provide updated disclosures as appropriate once the analysis is complete.

Senior Notes

The carrying value of our long-term debt is comprised as follows (in millions):



	February 3, 2018			January 28, 2017
2019 Senior Notes principal amount	$	350.0		$	350.0
2021 Senior Notes principal amount	475.0			475.0
Less: Unamortized debt financing costs	(7.1		)	(10.0		)
Long-term debt, net	$	817.9		$	815.0

2019 Senior Notes. In September 2014, we issued $350.0 million aggregate principal amount of unsecured 5.50% senior notes due October 1, 2019 (the "2019 Senior Notes"). The 2019 Senior Notes bear interest at the rate of 5.50% per annum with interest payable semi-annually in arrears on April 1 and October 1 of each year beginning on April 1, 2015. We incurred fees and expenses related to the 2019 Senior Notes offering of $6.3 million, which were capitalized during the third quarter of fiscal 2014 and are being amortized as interest expense over the term of the notes. The 2019 Senior Notes were sold in a private placement and are not registered under the U.S. Securities Act of 1933, as amended (the "Securities Act"). The 2019 Senior Notes were offered in the U.S. to “qualified institutional buyers” pursuant to the exemption from registration under Rule 144A of the Securities Act and in exempted offshore transactions pursuant to Regulation S under the Securities Act.

2021 Senior Notes. In March 2016, we issued $475.0 million aggregate principal amount of unsecured 6.75% senior notes due March 15, 2021 (the "2021 Senior Notes"). The 2021 Senior Notes bear interest at the rate of 6.75% per annum with interest payable semi-annually in arrears on March 15 and September 15 of each year beginning on September 15, 2016. The net proceeds from the offering were used for general corporate purposes, including acquisitions and dividends. We incurred fees and expenses related to the 2021 Senior Notes offering of $8.1 million, which were capitalized during the first quarter of fiscal 2016 and are being amortized as interest expense over the term of the notes. The 2021 Senior Notes were sold in a private placement and will not be registered under the Securities Act. The 2021 Senior Notes were offered in the U.S. to "qualified institutional buyers" pursuant to the exemption from registration under Rule 144A of the Securities Act and in exempted offshore transactions pursuant to Regulation S under the Securities Act.

The indentures governing the 2019 Senior Notes and the 2021 Senior Notes (together, the "Senior Notes") do not contain financial covenants but do contain covenants which place certain restrictions on us and our subsidiaries, including limitations on asset sales, additional liens, investments, stock repurchases, the incurrence of additional debt and the repurchase of debt that is junior to the Senior Notes. In addition, the indentures restrict payments of dividends to stockholders (other than dividends payable in shares of capital stock) if one of the following conditions exist: (i) an event of default has occurred, (ii) we could not incur additional debt under the general debt covenant of the indentures or (iii) the sum of the proposed dividend and all other dividends and other restricted payments made under the indentures from the date of the indentures governing the Senior Notes exceeds the sum of 50% of consolidated net income plus 100% of net proceeds from capital stock sales and other amounts set forth in and determined as provided in the indentures. These restrictions are subject to exceptions and qualifications, including that we can pay up to $175 million in dividends to stockholders in each fiscal year and we can pay dividends and make other restricted payments in an unlimited amount if our leverage ratio on a pro forma basis after giving effect to the dividend payment and other restricted payments would be less than or equal to 1.0:1.0.

The indentures contain customary events of default, including payment defaults, breaches of covenants, failure to pay certain judgments and certain events of bankruptcy, insolvency and reorganization. If an event of default occurs and is continuing, the principal amount of the Senior Notes, plus accrued and unpaid interest, if any, may be declared immediately due and payable. These amounts automatically become due and payable if an event of default relating to certain events of bankruptcy, insolvency or reorganization occurs.

Revolving Credit Facility

On November 20, 2017, we entered into a second amendment to our asset-based revolving credit facility (the “Amended Revolver”). The Amended Revolver increased the borrowing base capacity to $420 million and extended the maturity date from March 2019 to November 2022. The Amended Revolver maintains the existing $200 million expansion feature and $50 million letter of credit sublimit, and allows for an incremental $50 million first-in, last-out facility. The applicable margins for prime rate loans were reduced from a range of 0.25% to 0.75% to a range of 0.25% to 0.50% and, for LIBO rate loans, reduced from a range of 1.25% to 1.75% to a range of 1.25% to 1.50%. Other terms and covenants under the Amended Revolver remain substantially unchanged. The Amended Revolver is secured by substantially all of our assets and the assets of our domestic subsidiaries.

Borrowing availability under the Amended Revolver is limited to a borrowing base which allows us to borrow up to 90% of the appraisal value of the inventory, plus 90% of eligible credit card receivables, net of certain reserves. The borrowing base provides for borrowing of up to 92.5% of the appraisal value during the period between July 15 and October 15 of each year. Letters of credit reduce the amount available to borrow under the Amended Revolver by an amount equal to the face value of the letters of credit. Our ability to pay cash dividends, redeem options and repurchase shares is generally permitted, except under certain circumstances, including if either 1) excess availability under the Amended Revolver is less than 20%, or is projected to be within six months after such payment or 2) excess availability under the Amended Revolver is less than 15%, or is projected to be within six months after such payment, and the fixed charge coverage ratio, as calculated on a pro-forma basis for the prior 12 months, is 1.0:1.0 or less. In the event that excess availability under the Amended Revolver is at any time less than the greater of (1) $30 million or (2) 10% of the lesser of the total commitment or the borrowing base, we will be subject to a fixed charge coverage ratio covenant of 1.0:1.0.

The Amended Revolver places certain restrictions on us and our subsidiaries, including limitations on asset sales, additional liens, investments, loans, guarantees, acquisitions and the incurrence of additional indebtedness. Absent consent from our lenders, we may not incur more than $1 billion of senior secured debt and $750 million of additional unsecured indebtedness to be limited to $250 million in general unsecured obligations and $500 million in unsecured obligations to finance acquisitions valued at $500 million or more.

The per annum interest rate under the Amended Revolver is variable and is calculated by applying a margin (1) for prime rate loans of 0.25% to 0.50% above the highest of (a) the prime rate of the administrative agent, (b) the federal funds effective rate plus 0.50% and (c) the London Interbank Offered (“LIBO”) rate for a one month interest period as determined on such day plus 1.00%, and (2) for LIBO rate loans of 1.25% to 1.50% above the LIBO rate. The applicable margin is determined quarterly as a function of our average daily excess availability under the facility. In addition, we are required to pay a commitment fee of 0.25% for any unused portion of the total commitment under the Amended Revolver. As of February 3, 2018, the applicable margin was 0.25% for prime rate loans and 1.25% for LIBO rate loans.

The Amended Revolver provides for customary events of default with corresponding grace periods, including failure to pay any principal or interest when due, failure to comply with covenants, any material representation or warranty made by us or the borrowers proving to be false in any material respect, certain bankruptcy, insolvency or receivership events affecting us or our subsidiaries, defaults relating to certain other indebtedness, imposition of certain judgments and mergers or the liquidation of the Company or certain of its subsidiaries. During fiscal 2017, we cumulatively borrowed $373.0 million and repaid $373.0 million under our revolving credit facility. Average daily borrowings under the facility for fiscal 2017 were $19.1 million and our average interest rate on those borrowings was 2.96%. As of February 3, 2018, total availability under the Amended Revolver was $412.6 million, with no outstanding borrowings and outstanding standby letters of credit of $7.4 million. We are currently in compliance with the financial requirements of the Amended Revolver.

Luxembourg Line of Credit

Our Luxembourg subsidiary maintains a discretionary $20.0 million Uncommitted Line of Credit (the “Line of Credit”) with Bank of America. There is no term associated with the Line of Credit and Bank of America may withdraw the facility at any time without notice. The Line of Credit is available to our foreign subsidiaries for use primarily as a bank overdraft facility for short-term liquidity needs and for the issuance of bank guarantees and letters of credit to support operations. As of February 3, 2018, there were no cash overdrafts outstanding under the Line of Credit and bank guarantees outstanding totaled $9.8 million.

Leases [Abstract]

Leases

10. Leases

We lease retail stores, warehouse facilities, office space and equipment. These are generally leased under noncancelable agreements that expire at various dates through 2031 with various renewal options for additional periods. The agreements, which have been classified as operating leases, generally provide for minimum and, in some cases, percentage rentals and require us to pay all insurance, taxes and other maintenance costs. Leases with step rent provisions, escalation clauses or other lease concessions are accounted for on a straight-line basis over the lease term, which includes renewal option periods when we are reasonably assured of exercising the renewal options and includes “rent holidays” (periods in which we are not obligated to pay rent). Cash or lease incentives received upon entering into certain store leases (“tenant improvement allowances”) are recognized on a straight-line basis as a reduction to rent expense over the lease term, which includes renewal option periods when we are reasonably assured of exercising the renewal options. We record the unamortized portion of tenant improvement allowances as a part of deferred rent. We do not have leases with capital improvement funding. Percentage rentals are based on sales performance in excess of specified minimums at various stores and are accounted for in the period in which the amount of percentage rentals can be accurately estimated.

Rent expense under operating leases was as follows (in millions):



	Fiscal Year
	2017		2016		2015
Minimum	$	433.5	$	437.4	$	394.5
Percentage rentals	8.9		6.9		7.8
Total rent expense	$	442.4	$	444.3	$	402.3

Future minimum annual rentals, excluding percentage rentals, required under leases that had initial, noncancelable lease terms greater than one year, as of February 3, 2018, are as follows (in millions):

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	11. Commitments and Contingencies Commitments We had bank guarantees relating primarily to international store leases and other commercial commitments totaling $25.5 million and $24.5 million as of February 3, 2018 and January 28, 2017, respectively. See Note 10, "Leases," for information regarding commitments related to our noncancelable operating leases. Legal Proceedings In the ordinary course of business, we are, from time to time, subject to various legal proceedings, including matters involving wage and hour employee class actions, stockholder actions and consumer class actions. We may enter into discussions regarding settlement of these and other types of lawsuits, and may enter into settlement agreements, if we believe settlement is in the best interest of our stockholders. We do not believe that any such existing legal proceedings or settlements, individually or in the aggregate, will have a material effect on our financial condition, results of operations or liquidity. Certain of our French subsidiaries have been under audit by the French Tax Administration (the "FTA") for fiscal years 2008 through 2015. We received tax reassessment notices pursuant to which the FTA asserted that the French subsidiaries were ineligible to claim certain tax deductions from November 4, 2008, through January 31, 2013, which has resulted in a tax collection notice received on January 16, 2018 in the amount of approximately €80.0 million. We may receive additional tax reassessments in material amounts for subsequent fiscal years. We filed a response to each reassessment and intend to vigorously contest the reassessments through administrative procedures. If we are unable to resolve this matter through administrative remedies at the FTA, we plan to pursue judicial remedies. We believe our tax positions will be sustained and have not taken a reserve for any potential adjustment based on the reassessment. If we were not to prevail, then the adjustment to our income tax provision could be material.

Stock Incentive Plan

12. Common Stock and Share-Based Compensation

Common Stock

The holders of Class A Common Stock are entitled to one vote per share on all matters to be voted on by stockholders. Holders of Class A Common Stock will share in any dividend declared by the Board of Directors. In the event of our liquidation, dissolution or winding up, all holders of common stock are entitled to share ratably in any assets available for distribution to holders of shares of common stock.

Share Repurchase Activity. Since January 2010, our Board of Directors has authorized several share repurchase programs authorizing our management to repurchase our Class A Common Stock. Since the beginning of fiscal 2011, each individual authorization has been $500 million. We generally seek Board of Directors’ approval for a new authorization before the existing program is fully utilized to ensure we maintain availability under a repurchase program. Repurchased shares are subsequently retired. Share repurchases are generally recorded as a reduction to additional paid-in capital; however, in the event that share repurchases would cause additional paid-in capital to be reduced below zero, any excess is recorded as a reduction to retained earnings.

We did not repurchase shares during fiscal 2017. The following table summarizes our share repurchase activity during fiscal 2016 and 2015 (in millions, except average price paid per share):



	Fiscal Year
	2016		2015
Total number of shares purchased	3.0		5.2
Average price per share	$	24.94	$	38.68
Aggregate value of shares purchased	$	75.1	$	202.0

As of February 3, 2018, we have $170.2 million remaining under our latest authorization from November 2014.

Dividends. We paid a total of $1.44 per share in dividends in fiscal 2015 and a total of $1.48 per share fiscal 2016. In fiscal 2017, we paid annual dividends of $1.52 per share of Class A Common Stock, totaling approximately $155.2 million. On February 20, 2018, our Board of Directors declared a quarterly cash dividend of $0.38 per share of Class A Common Stock payable March 20, 2018. Future dividends will be subject to approval by our Board of Directors.

Share-Based Compensation

Effective June 2013, our stockholders voted to adopt the Amended and Restated 2011 Incentive Plan (the “Amended 2011 Incentive Plan”) to provide for issuance under the 2011 Incentive Plan of our Class A Common Stock. The Amended 2011 Incentive Plan provides a maximum aggregate amount of 9.25 million shares of Class A Common Stock with respect to which options may be granted and provides for a grant of incentive stock options, non-qualified stock options, stock appreciation rights, performance awards, restricted stock and other share-based awards. The options to purchase Class A common shares are issued at fair market value of the underlying shares on the date of grant. In general, the options vest and become exercisable in equal annual installments over a three-year period, and expire ten years from the grant date. Shares issued upon exercise of options and vesting of restricted stock awards are newly issued shares. Options and restricted shares granted after June 21, 2011 are issued under the 2011 Incentive Plan.

Effective June 2009, our stockholders voted to amend the Third Amended and Restated 2001 Incentive Plan (the “2001 Incentive Plan”) to provide for issuance under the 2001 Incentive Plan of our Class A Common Stock. The 2001 Incentive Plan provided a maximum aggregate amount of 46.5 million shares of Class A Common Stock with respect to which options may have been granted and provided for the granting of incentive stock options, non-qualified stock options, and restricted stock. The options to purchase Class A common shares were issued at fair market value of the underlying shares on the date of grant. In general, the options vested and became exercisable in equal annual installments over a three-year period, commencing one year after the grant date, and expire ten years from the grant date. Options and restricted shares granted on or before June 21, 2011 were issued under the 2001 Incentive Plan.

Stock Options

We record stock-based compensation expense in earnings based on the grant-date fair value of options granted. The fair value of each option grant is estimated on the date of grant using the Black-Scholes option pricing model. This valuation model requires the use of subjective assumptions, including expected option life and expected volatility. We use historical data to estimate the option life and the employee forfeiture rate, and use historical volatility when estimating the stock price volatility. We have not historically experienced material forfeitures with respect to the employees who currently receive stock option grants. There were no options granted during fiscal 2017 and 2016.

A summary of our stock option activity during fiscal 2017 is presented below:



	Shares		Weighted- Average Exercise Price
Balance, January 28, 2017	1,327,353		$	35.43
Exercised	(6,300	)	$	20.32
Expired	(127,028	)	$	37.56
Balance, February 3, 2018	1,194,025		$	35.30

The following table summarizes information as of February 3, 2018 concerning outstanding and exercisable options:



	Options Outstanding & Exercisable
Range of Exercise Prices	Number Outstanding & Exercisable	Weighted- Average Remaining Life (Years)	Weighted- Average Exercise Price
$20.32 - $38.52	844,075	4.65	$	29.23
$49.95	349,950	0.01	$	49.95
$20.32 - $49.95	1,194,025	3.29	$	35.30

The total intrinsic value of options exercised during fiscal 2017, 2016 and 2015 was $0.1 million, $0.1 million, and $6.7 million, respectively. There was no intrinsic value of both options exercisable and options outstanding, as of February 3, 2018.

The fair value of each option is recognized as compensation expense on a straight-line basis between the grant date and the date the options become fully vested. During fiscal 2017, 2016 and 2015, we included compensation expense relating to the grant of these options in the amount of $0.1 million, $0.9 million and $2.6 million, respectively, in selling, general and administrative expenses. As of February 3, 2018, there was no unrecognized compensation expense related to our stock options.

Restricted Stock Awards

The fair value of restricted stock awards is recognized as compensation expense on a straight-line basis between the grant date and the date the restricted stock awards become fully vested. We grant restricted stock awards to certain of our employees, officers and non-employee directors. We estimate the fair value of restricted stock awards on the grant date based on the quoted market price of our common stock.

Time-based restricted stock awards generally vest in equal annual installments over a three-year period on the anniversary of the date of issuance, subject to continued service to the Company, and subject further to accelerated vesting in the case of retirement eligibility and certain termination events.

Performance-based restricted stock awards generally vest as a lump sum on the third anniversary of the date of issuance. Restricted stock awards subject to performance measures may generally be earned in greater or lesser percentages if targets are exceeded or not achieved by specified amounts.

The following table presents a summary of our restricted stock awards activity during fiscal 2017:



	Time-Based Restricted Stock Awards				Performance-Based Restricted Stock Awards
	Shares		Weighted- Average Grant Date Fair Value		Shares		Weighted- Average Grant Date Fair Value
Nonvested shares at January 28, 2017	811,838		$	33.33	505,190		$	35.87
Granted	596,412		$	24.94	287,670		$	25.28
Vested	(466,030	)	$	33.41	(60,474	)	$	39.74
Forfeited	(29,860	)	$	28.73	(179,197	)	$	39.30
Nonvested shares at February 3, 2018	912,360		$	27.96	553,189		$	28.83

In fiscal 2016, we granted 602,414 shares of time-based restricted stock with a weighted-average grant date fair value of $30.18. We also granted 206,580 shares of performance-based restricted stock with a weighted-average grant fair value of $30.54.

During fiscal 2017, 2016 and 2015, we included compensation expense relating to the grants of restricted shares in the amounts of $25.5 million, $16.9 million and $27.3 million, respectively, in selling, general and administrative expenses in the accompanying consolidated statements of operations. The fiscal 2017 and 2016 compensation expense associated with the restricted shares is net of adjustments totaling $2.9 million and $5.9 million, respectively, relating to performance measures that were not fully met. As of February 3, 2018, there was $16.3 million of unrecognized compensation expense related to nonvested restricted shares that is expected to be recognized over a weighted-average period of 1.6 years.

The total fair value of restricted stock awards vested, as of their respective vesting dates, was $12.5 million, $27.6 million, and $34.1 million during fiscal 2017, 2016 and 2015.

Earnings Per Share [Abstract]

Computation of Net Income (Loss) per Common Share

13. Earnings Per Share

Basic net income per common share is computed by dividing the net income available to common stockholders by the weighted-average number of common shares outstanding during the period. Diluted net income per common share is computed by dividing the net income available to common stockholders by the weighted-average number of common shares outstanding and potentially dilutive securities outstanding during the period. Potentially dilutive securities include stock options and unvested restricted stock outstanding during the period, using the treasury stock method. Potentially dilutive securities are excluded from the computations of diluted earnings per share if their effect would be antidilutive. A reconciliation of shares used in calculating basic and diluted net income per common share is as follows (in millions, except per share data):



	Fiscal Year
	2017		2016		2015
Net income	$	34.7	$	353.2	$	402.8

Employees' Defined Contribution Plan	14. Employees' Defined Contribution Plan We sponsor a defined contribution plan (the “Savings Plan”) for the benefit of substantially all of our U.S. employees who meet certain eligibility requirements, primarily age and length of service. The Savings Plan allows employees to invest up to 60%, subject to IRS limitations, of their eligible gross cash compensation invested on a pre-tax basis. Our optional contributions to the Savings Plan are generally in amounts based upon a certain percentage of the employees’ contributions. Our contributions to the Savings Plan during fiscal 2017, 2016 and 2015, were $8.4 million, $7.8 million and $6.3 million, respectively.

Summary of Significant Accounting Policies (Policies)	Feb. 03, 2018
Accounting Policies [Abstract]
Nature of Operations [Text Block]	The Company GameStop Corp. (“GameStop,” “we,” “us,” “our,” or the “Company”) is a global family of specialty retail brands that makes the most popular technologies affordable and simple. Within our family of brands, we are the world’s largest omnichannel video game retailer, the largest AT&T® (“AT&T”) authorized retailer, the largest Apple© (“Apple”) certified products reseller, and the owner of www.thinkgeek.com, one of the world’s largest sellers of collectible pop-culture themed products. As of February 3, 2018, GameStop's retail network and family of brands include 7,276 company-operated stores in the United States, Canada, Australia and Europe. We have five reportable segments, which are comprised of four geographic Video Game Brands segments—United States, Canada, Australia and Europe—and a Technology Brands segment. Our Technology Brands segment includes our Spring Mobile and Simply Mac businesses. Spring Mobile owns and operates our AT&T branded wireless retail stores.
Concentration Risk Disclosure [Text Block]	Our largest vendors in our Video Game Brands segments are Nintendo, Sony, Microsoft, Activision Blizzard and Electronic Arts, which accounted for 22%, 20%, 10%, 6% and 6%, respectively, of our new product purchases in fiscal year 2017; 10%, 24%, 14%, 6% and 7%, respectively, in fiscal year 2016; and 11%, 27%, 19%, 9% and 10%, respectively, in fiscal year 2015.
Consolidation, Policy [Policy Text Block]	Basis of Presentation and Consolidation Our consolidated financial statements include our accounts and the accounts of our wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. Our fiscal year is composed of the 52 or 53 weeks ending on the Saturday closest to the last day of January. Fiscal year 2017 consisted of the 53 weeks ended on February 3, 2018 ("fiscal 2017"). Fiscal year 2016 consisted of the 52 weeks ended on January 28, 2017 ("fiscal 2016"). Fiscal year 2015 consisted of the 52 weeks ended on January 30, 2016 ("fiscal 2015").
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. In preparing these financial statements, we have made our best estimates and judgments of certain amounts included in the financial statements, giving due consideration to materiality. Changes in the estimates and assumptions used by us could have a significant impact on our financial results. Actual results could differ from those estimates.
Cash and Cash Equivalents	Cash and Cash Equivalents We consider all short-term, highly-liquid instruments purchased with an original maturity of three months or less to be cash equivalents. Our cash and cash equivalents are carried at cost, which approximates market value, and consist primarily of time deposits with highly rated commercial banks. From time to time depending upon interest rates, credit worthiness and other factors, we invest in money market investment funds holding direct U.S. Treasury obligations.
Restricted Cash	Restricted Cash We consider bank deposits serving as collateral for bank guarantees issued on behalf of our foreign subsidiaries as restricted cash, which is included in other noncurrent assets in our consolidated balance sheets. Our restricted cash was $14.9 million and $10.2 million as of February 3, 2018 and January 28, 2017, respectively.
Merchandise Inventories	Merchandise Inventories Our merchandise inventories are carried at the lower of cost or market generally using the average cost method. Under the average cost method, as new product is received from vendors, its current cost is added to the existing cost of product on-hand and this amount is re-averaged over the cumulative units. Pre-owned video game products traded in by customers are recorded as inventory at the amount of the store credit given to the customer. We are required to make adjustments to inventory to reflect potential obsolescence or over-valuation as a result of cost exceeding market. In valuing inventory, we consider quantities on hand, recent sales, potential price protections, returns to vendors and other factors. Our ability to assess these factors is dependent upon our ability to forecast customer demand and to provide a well-balanced merchandise assortment. Inventory is adjusted based on anticipated physical inventory losses or shrinkage and actual losses resulting from periodic physical inventory counts. Inventory reserves as of February 3, 2018 and January 28, 2017 were $59.2 million and $59.0 million, respectively.
Property and Equipment	Property and Equipment Property and equipment are carried at cost less accumulated depreciation and amortization. Depreciation on furniture, fixtures and equipment is computed using the straight-line method over their estimated useful lives ranging from two to ten years. Maintenance and repairs are expensed as incurred, while betterments and major remodeling costs are capitalized. Leasehold improvements are capitalized and amortized over the shorter of their estimated useful lives or the terms of the respective leases, including option periods in which the exercise of the option is reasonably assured (generally ranging from two to ten years). Costs incurred in purchasing management information systems are capitalized and included in property and equipment. These costs are amortized over their estimated useful lives from the date the technology becomes operational. Our total depreciation expense was $138.4 million, $151.7 million and $144.9 million for fiscal 2017, 2016 and 2015, respectively. We periodically review our property and equipment when events or changes in circumstances indicate that its carrying amounts may not be recoverable or its depreciation or amortization periods should be accelerated. We assess recoverability based on several factors, including our intention with respect to our stores and those stores’ projected undiscounted cash flows. An impairment loss is recognized for the amount by which the carrying amount of the assets exceeds its fair value, determined based on an estimate of discounted future cash flows. We recorded impairment losses of $18.2 million, $19.4 million and $4.4 million in fiscal 2017, 2016 and 2015, respectively. See Note 2, "Asset Impairments," for further information regarding our asset impairment charges.
Business Combinations Policy [Policy Text Block]	Business Combinations Business combinations are accounted for under the acquisition method of accounting. Under this method, the assets acquired and liabilities assumed are recognized at their respective fair values as of the date of acquisition. The excess, if any, of the acquisition price over the fair values of the assets acquired and liabilities assumed is recorded as goodwill. For significant acquisitions, we utilize third-party appraisal firms to assist us in determining the fair values for certain assets acquired and liabilities assumed. Adjustments to the fair values of assets acquired and liabilities assumed are made until we obtain all relevant information regarding the facts and circumstances that existed as of the acquisition date, not to exceed one year from the date of the acquisition (the "measurement period"). Upon the conclusion of the measurement period, any subsequent adjustments are recorded to earnings. Costs associated with business acquisitions are expensed as incurred. Over the past several years, we have acquired certain AT&T authorized retailers and in 2015, we acquired Geeknet, Inc. an online and wholesale retailer of collectibles and other products. See Note 3, "Acquisitions and Divestitures" for additional information.
Goodwill	Goodwill and Intangible Assets Goodwill represents the excess purchase price over tangible net assets and identifiable intangible assets acquired. Intangible assets are recorded apart from goodwill if they arise from a contractual right and are capable of being separated from the entity and sold, transferred, licensed, rented or exchanged individually. We are required to evaluate goodwill and other intangible assets not subject to amortization for impairment at least annually. This annual test is completed at the beginning of the fourth quarter of each fiscal year or when circumstances indicate the carrying value of the goodwill or other intangible assets might be impaired. Goodwill has been assigned to reporting units for the purpose of impairment testing. We have five operating segments, including Video Game Brands in the United States, Canada, Australia and Europe, and Technology Brands in the United States, which also define our reporting units based upon the similar economic characteristics of operations within each segment, including the nature of products, product distribution and the type of customer and separate management within these businesses. In order to test goodwill for impairment, we compare a reporting unit's carrying amount to its estimated fair value. If the reporting unit’s carrying value exceeds its estimated fair value, then an impairment charge is recorded in the amount of the excess. The estimated fair value of a reporting unit is determined based on its discounted cash flows, which are derived from our long-term financial forecasts. The discounted cash flows analysis requires significant assumptions including, among others, a discount rate and a terminal value. Goodwill impairment charges of $32.8 million were recognized in fiscal 2017. See Note 6, "Goodwill and Intangible Assets" for additional information. No goodwill impairment charges were recognized in fiscal 2016 and 2015.
Goodwill and Intangible Assets, Intangible Assets, Policy [Policy Text Block]	Our indefinite-lived intangible assets consist of dealer agreements and trade names. Intangible assets that are determined to have an indefinite life are not amortized, but are required to be evaluated at least annually for impairment. If the carrying value of an individual indefinite-lived intangible asset exceeds its fair value, such individual indefinite-lived intangible asset is impaired by the amount of the excess. The fair value of our dealer agreements are estimated using a discounted cash flow analysis known as the Greenfield Method, which assumes that a business, at its inception, owns only dealer agreements and must make capital expenditure, working capital and other investments to ramp up its operations to a level that is comparable to its current operations. The fair value of our trade names are estimated by using a relief-from-royalty approach, which assumes the value of the trade name is the discounted cash flows of the amount that would be paid by a hypothetical market participant had they not owned the trade name and instead licensed the trade name from another company. As a result of our fiscal 2017 and fiscal 2016 annual impairment testing, we recognized impairment charges totaling $339.8 million and $14.4 million, respectively, associated with our dealer agreements and trade names. See Note 6, "Goodwill and Intangible Assets" for additional information. No impairment charges associated with our indefinite-lived intangible assets were recognized in fiscal 2015. Our definite-lived intangible assets consist primarily of customer relationships, leasehold rights, advertising relationships and amounts attributed to favorable leasehold interests recorded as a result of business acquisitions. The estimated useful life and amortization methodology of intangible assets are determined based on the period in which they are expected to contribute directly to cash flows. Intangible assets that are determined to have a definite life are amortized over that period.
Revenue Recognition	Revenue Recognition We recognize revenue when the sales price is fixed or determinable, collection is reasonably assured and the customer takes possession of the merchandise, or in the case of commissions, when the commission-generating activity has been performed. Revenues do not include sales taxes or other taxes collected from customers. Revenue from the sales of our products is recognized at the time of sale, net of sales discounts and net of an estimated sales return reserve, based on historical return rates, with a corresponding reduction in cost of sales. Our sales return policy is generally limited to 30 days or less and as such our sales returns are, and historically have been, immaterial. The sales of pre-owned video game products are recorded at the retail price charged to the customer. Advertising revenues for Game Informer are recorded upon release of magazines for sale to consumers. Subscription revenues for our PowerUp Rewards loyalty program and magazines are recognized on a straight-line basis over the subscription period. Revenue from the sales of product replacement plans is recognized on a straight-line basis over the coverage period. Customer liabilities and other deferred revenues for our PowerUp Rewards loyalty program, gift cards, customer credits, magazines and product replacement plans are included in accrued liabilities (see Note 8, "Accrued Liabilities"). We also sell a variety of digital products which generally allow consumers to download software or play games on the internet. Certain of these products do not require us to purchase inventory or take physical possession of, or take title to, inventory. When purchasing these products from us, consumers pay a retail price and we earn a commission based on a percentage of the retail sale as negotiated with the product publisher. We recognize these commissions as revenue at the time of sale of these digital products. Our Spring Mobile business earns commission revenue as an AT&T authorized retailer related to the activation of new wireless customers, the activation of enhanced or upgraded features on existing wireless customer plans and certain other commission incentive opportunities that may be offered to us by AT&T. We have determined that we are not deemed the obligor on the underlying wireless services contracts that give rise to this commission revenue; therefore, commission revenue is recognized at the point at which the commission-generating activity has been performed, which is generally driven by customer activation. Commissions are recognized net of an allowance for chargebacks from AT&T for estimated customer cancellations, which is periodically assessed and adjusted to reflect historical cancellation experience. In May 2014, the Financial Accounting Standards Board ("FASB") issued a comprehensive update to current revenue accounting standards; see "—Recent Accounting Pronouncements" for additional information.
Customer Liabilities	Customer Liabilities We establish a liability upon the issuance of merchandise credits and the sale of gift cards. Revenue is subsequently recognized when the credits and gift cards are redeemed. In addition, breakage is recognized quarterly on unused customer liabilities older than two years to the extent that our management believes the likelihood of redemption by the customer is remote, based on historical redemption patterns. To the extent that future redemption patterns differ from those historically experienced, there will be variations in the recorded breakage. Breakage is recorded in cost of sales in our consolidated statements of operations.
Cost of Sales, Vendor Allowances, Policy [Policy Text Block]	Vendor Arrangements We and most of our largest vendors participate in cooperative advertising programs and other vendor marketing programs in which the vendors provide us with cash consideration in exchange for marketing and advertising the vendors’ products. Our accounting for cooperative advertising arrangements and other vendor marketing programs results in a significant portion of the consideration received from our vendors reducing the product costs in inventory rather than as an offset to our marketing and advertising costs. The consideration serving as a reduction in inventory is recognized in cost of sales as inventory is sold. The amount of vendor allowances to be recorded as a reduction of inventory is determined based on the nature of the consideration received and the merchandise inventory to which the consideration relates. We apply a sell-through rate to determine the timing in which the consideration should be recognized in cost of sales. Consideration received that relates to video game products that have not yet been released to the public is deferred as a reduction of inventory. The cooperative advertising programs and other vendor marketing programs generally cover a period from a few days up to a few weeks and include items such as product catalog advertising, in-store display promotions, internet advertising, co-op print advertising and other programs. The allowance for each event is negotiated with the vendor and requires specific performance by us to be earned. Vendor allowances of $162.5 million, $184.3 million and $208.2 million were recorded as a reduction of cost of sales for fiscal 2017, 2016 and 2015, respectively.
Loyalty Expenses	Loyalty Expenses Our PowerUp Rewards loyalty program allows enrolled members to earn points on purchases that can be redeemed for rewards that include discounts or merchandise. We estimate the net cost of the rewards that will be issued and redeemed and record this cost and the associated balance sheet liability as points are accumulated by loyalty program members. The two primary estimates utilized to record the balance sheet liability for loyalty points earned by members are the estimated redemption rate and the estimated weighted-average cost per point redeemed. We use historical redemption rates experienced under the loyalty program as a basis to estimate the ultimate redemption rate of points earned. The estimated weighted-average cost per point redeemed, used to estimate future redemption costs, is based on our most recent actual costs incurred to fulfill points that have been redeemed by our loyalty program members and is adjusted for recent changes in redemption costs, including the mix of rewards redeemed. We continually evaluate our methodology and assumptions based on developments in redemption patterns, cost per point redeemed and other factors. Changes in the ultimate redemption rate and weighted-average cost per point redeemed have the effect of either increasing or decreasing the liability through the current period provision by an amount estimated to cover the cost of all points previously earned but not yet redeemed by loyalty program members as of the end of the reporting period. The cost of free or discounted product is recognized in cost of sales and the associated liability is included in accrued liabilities. The reserve is released when loyalty program members redeem their respective points and the corresponding rewards are recorded to cost of goods sold in the period of redemption. The cost of administering the loyalty program, including program administration fees, program communications and cost of loyalty cards, is recognized in selling, general and administrative expenses.
Cost of Sales and Selling, General and Administrative Expenses Classification	Cost of Sales and Selling, General and Administrative Expenses Classification The classification of cost of sales and selling, general and administrative expenses varies across the retail industry. We include purchasing, receiving and distribution costs in selling, general and administrative expenses in the consolidated statements of operations.
Selling, General and Administrative Expenses, Policy [Policy Text Block]	We include processing fees associated with purchases made by check and credit cards in cost of sales in the consolidated statements of operations.
Advertising Expenses	Advertising Expenses We expense advertising costs for television, newspapers and other media when the advertising takes place. Advertising expenses for fiscal 2017, 2016 and 2015 totaled $83.3 million, $76.6 million and $66.6 million, respectively.
Income Taxes	Income Taxes Income tax expense includes federal, state, local and international income taxes. Income taxes are accounted for utilizing an asset and liability approach and deferred tax assets and liabilities are recognized for the tax consequences of temporary differences between the financial reporting basis and the tax basis of existing assets and liabilities using enacted tax rates. Deferred tax assets and liabilities are measured using the enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the period that includes the enactment date. Valuation allowances are recorded to reduce deferred tax assets to the amount that will more likely than not be realized. We maintain liabilities for uncertain tax positions until examination of the tax year is completed by the applicable taxing authority, available review periods expire or additional facts and circumstances cause us to change our assessment of the appropriate accrual amount. See Note 7, "Income Taxes," for additional information. We plan on permanently reinvesting our undistributed foreign earnings outside the United States. Where foreign earnings are permanently reinvested, no provision for federal income or foreign withholding taxes is made. Should we have undistributed foreign earnings that are not permanently reinvested, United States income tax expense and foreign withholding taxes will be provided for at the time the earnings are generated.
Lease Accounting	Leases We lease retail stores, warehouse facilities, office space and equipment. These assets and properties are generally leased under noncancelable agreements that expire at various dates through 2031 with various renewal options for additional periods. The agreements, which are classified as operating leases, generally provide for minimum and, in some cases, percentage rentals and require us to pay all insurance, taxes and other maintenance costs. Leases with step rent provisions, escalation clauses or other lease concessions are accounted for on a straight-line basis over the lease term, which includes renewal option periods when we are reasonably assured of exercising the renewal options and includes “rent holidays” (periods in which we are not obligated to pay rent). Cash or lease incentives received upon entering into certain store leases (“tenant improvement allowances”) are recognized on a straight-line basis as a reduction to rent expense over the lease term, which includes renewal option periods when we are reasonably assured of exercising the renewal options. We record the unamortized portion of tenant improvement allowances as a part of deferred rent. We do not have leases with capital improvement funding. Percentage rentals are based on sales performance in excess of specified minimums at various stores and are accounted for in the period in which the amount of percentage rentals can be accurately estimated.
Foreign Currency Translation	Foreign Currency Generally, we have determined that the functional currencies of our foreign subsidiaries are the subsidiaries’ local currencies. The assets and liabilities of the subsidiaries are translated at the applicable exchange rate as of the end of the balance sheet date and revenue and expenses are translated at an average rate over the period. Currency translation adjustments are recorded as a component of other comprehensive income. Net gains from foreign currency transactions and derivatives are included in selling, general and administrative expenses and were $2.4 million, $4.5 million and $1.6 million in fiscal 2017, 2016 and 2015, respectively. The foreign currency transaction gains and losses are primarily due to the decrease or increase in the value of the U.S. dollar compared to the functional currencies of the countries in which we operate internationally. We use forward exchange contracts, foreign currency options and cross-currency swaps (together, the “foreign currency contracts”) to manage currency risk primarily related to foreign-currency denominated intercompany assets and liabilities and certain other foreign currency assets and liabilities. These foreign currency contracts are not designated as hedges and, therefore, changes in the fair values of these derivatives are recognized in earnings, thereby offsetting the current earnings effect of the re-measurement of related intercompany loans and foreign currency assets and liabilities. See Note 4, "Fair Value Measurements and Financial Instruments," for additional information regarding our foreign currency contracts.
New Accounting Pronouncements	Recent Accounting Pronouncements In August 2017, the FASB issued ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities. The new guidance is intended to more closely align hedge accounting with entities’ hedging strategies, simplify the application of hedge accounting and increase the transparency of hedging programs. The new guidance is effective for fiscal years beginning after December 15, 2018, with early adoption permitted. We do not anticipate that adoption of this standard will have a material impact to our consolidated financial statements. In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows, Classification of Certain Cash Receipts and Cash Payments, which provides guidance on eight specific cash flow issues in regard to how cash receipts and cash payments are presented and classified in the statement of cash flows. The updated standard is effective for fiscal years beginning after December 15, 2017, including interim periods within those years, with early adoption permitted. The amendments in the ASU should be adopted on a retrospective basis unless it is impracticable to apply, in which case the amendments should be applied prospectively as of the earliest date practicable. We are currently evaluating the impact that this standard will have on our consolidated financial statements and disclosures. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers, which sets forth a new five-step revenue recognition model that replaces the prior revenue recognition guidance in its entirety. The underlying principle of the new standard is that an entity will recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects what it expects in exchange for the goods or services. The updated standard also requires additional disclosures on the nature, timing, and uncertainty of revenue and related cash flows. In August 2015, the FASB issued ASU 2015-14, Revenue from Contracts with Customers: Deferral of the Effective Date, which delayed the effective date of ASU 2014-09 by one year to December 15, 2017 (with early adoption permitted). In 2016, the FASB issued several ASUs that further amended the new revenue standard in the areas of principal versus agent evaluation, licenses of intellectual property, identifying performance obligations, and other clarifications and technical corrections. Entities may use either a full retrospective or modified retrospective transition approach in applying these ASUs. The new revenue standard will primarily impact the accounting of our PowerUp Rewards loyalty program and the recognition of breakage associated with our gift cards liability. For our loyalty program, we currently estimate the net cost of the rewards that will be issued and redeemed and record this cost (presented as cost of sales) and the associated balance sheet liability as points are accumulated by our loyalty program members. Under the new standard, the transaction price will be allocated between the product(s) sold and loyalty points earned, where the portion allocated to the loyalty points will be initially recorded as deferred revenue and subsequently recognized as revenue upon redemption or expiration of the loyalty points. Estimated breakage on unused gift cards and merchandise credit liabilities is currently recognized on a quarterly basis (recorded to cost of sales) for balances older than two years to the extent that we believe the likelihood of redemption is remote. Under the new standard, we will recognize breakage in revenue based on and in proportion to historical redemption patterns, regardless of the age of the unused gift cards and merchandise credit liabilities. We will adopt the new standard in the first quarter of fiscal 2018, using the modified-retrospective transition approach. Under this approach, we will apply the new revenue standard on a prospective basis, effective February 4, 2018, and record adjustments to our fiscal 2018 opening balance sheet (as of February 4, 2018) to reflect the cumulative effect of the new revenue standard. We will also provide quantitative and qualitative disclosures of the new standard’s impact to each of our financial statement line items during fiscal 2018. The cumulative-effect adjustment will include a reduction of our gift card and customer deposit liabilities of approximately $46 million, an increase to our loyalty program liabilities of approximately $28 million and a net increase to our retained earnings of approximately $18 million (approximately $12 million, net of tax). In addition, the adoption of the new standard will result in expanded revenue recognition disclosures. We do not expect the adoption of the new revenue standard to have a material impact to our consolidated statements of operations or statements of cash flows. In February 2016, the FASB issued ASU 2016-02, Leases. The standard requires a lessee to recognize a liability related to lease payments and an offsetting right-of-use asset representing a right to use the underlying asset for the lease term on the balance sheet. Entities are required to use a modified retrospective transition approach for leases that exist or are entered into after the beginning of the earliest comparative period presented in the financial statements, with certain reliefs available. The ASU is effective for fiscal years, and interim periods within those years, beginning after December 15, 2018, with early adoption permitted. We are currently evaluating the overall impact to our consolidated financial statements, though we expect the adoption to result in a material increase in the assets and liabilities reflected in our consolidated balance sheets.

New Accounting Pronouncements or Change in Accounting Principle [Line Items]
New Accounting Pronouncements and Changes in Accounting Principles [Text Block]	Recently Adopted Accounting Pronouncements In January 2017, the FASB issued Accounting Standard Update ("ASU") 2017-04, Intangibles—Goodwill and Other, Simplifying the Test for Goodwill Impairment, which simplifies how an entity is required to test goodwill for impairment by eliminating Step 2 from the goodwill impairment test. Step 2 measures a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill and the carrying amount. Instead, entities will record an impairment charge based on the excess of a reporting unit's carrying amount over its estimated fair value. We early adopted this updated standard, effective January 29, 2017. In October 2016, the FASB issued ASU 2016-16, Accounting for Income Taxes: Intra-Entity Asset Transfers of Assets Other than Inventory, which eliminates the exception to defer the tax effects of intra-entity asset transfers (intercompany sales). Prior to this update, the tax effects of intra-entity asset transfers were deferred until the transferred asset was sold to a third party or otherwise recovered through use, which was an exception to the general requirement for comprehensive recognition of current and deferred income taxes. We early adopted this updated standard, effective January 29, 2017, and as a result we recognize tax expense or benefit from intercompany sales of assets other than inventory in the period in which the transaction occurs. In March 2016, the FASB issued ASU 2016-09, Improvements to Employee Share-Based Payment Accounting, which simplifies several aspects of accounting for employee share-based payment transactions. The amendments of the updated standard include, among other things, the requirement to recognize excess tax benefits and deficiencies through earnings and present the related cash flows in operating activities in the statement of cash flows, the election of a policy to either estimate forfeitures when determining periodic expense or recognize actual forfeitures when they occur, and an increase in the allowable income tax withholding from the minimum to maximum statutory rate and its classification in the statement of cash flows. As a result of the adoption of this updated standard, effective January 29, 2017, excess tax benefits and deficiencies are recognized in our results of operations and are presented in cash flows from operating activities in our statement of cash flows on a prospective basis. In addition, we elected to recognize actual forfeitures of stock-based awards as they occur. The adoption of this updated standard did not result in a material impact to our consolidated financial statements.

Business Combination, Contingent Consideration Arrangements, Description			In August 2016, we acquired certain assets from Cellular World and Red Skye Wireless (see Note 3, "Acquisitions and Divestitures"). The purchase price included two contingent payments with an acquisition-date liability of $43.2 million representing the total estimated fair value of the contingent consideration. The first payment of $20.0 million was contingent on the relocation of certain stores and was paid in August 2017. The second payment was variable and contingent on the sales performance of certain acquired stores during calendar year 2017. Based on the actual sales performance of these stores, we recognized an $11.0 million adjustment to reduce the contingent liability to $12.2 million during fiscal 2017, which is due in the first quarter of 2018.

Goodwill impairments	$ 32,800,000
Goodwill, Impaired, Facts and Circumstances Leading to Impairment	The impairment was the result of a decline in the projected profitability and store count growth in our Technology Brands business, primarily associated with Spring Mobile. The lower projected profitability is due to the negative impact of a longer upgrade cycle for new mobile devices and changes made by AT&T to the compensation structure in 2017. While Technology Brands remains profitable, we currently do not expect to invest and grow the store count at the levels in previous long-term financial forecasts.

(2)In fiscal 2016, we adopted a plan of reorganization specific to certain foreign operations which resulted in our ability to recognize the benefit of foreign net operating loss carryforwards that were previously unrecognized in affected jurisdictions. As a result, we recognized a tax benefit of $42.1 million in the fourth quarter of fiscal 2016, which is subject to a partial valuation allowance of $14.8 million. The valuation allowance established for this tax benefit is reflected in the line item “Change in valuation allowance.”

Debt Instrument, Covenant Description			The indenture governing the Senior Notes does not contain financial covenants but does contain covenants which place certain restrictions on us and our subsidiaries, including limitations on asset sales, additional liens, investments, stock repurchases, the incurrence of additional debt and the repurchase of debt that is junior to the Senior Notes.
Debt Instrument, Dividend Restriction			In addition, the indenture restricts payments of dividends to stockholders (other than dividends payable in shares of capital stock) if one of the following conditions exist: (i) an event of default has occurred, (ii) we could not incur additional debt under the general debt covenant of the indenture or (iii) the sum of the proposed dividend and all other dividends and other restricted payments made under the indenture from the date of the indenture exceeds the sum of 50% of consolidated net income plus 100% of net proceeds from capital stock sales and other amounts set forth in and determined as provided in the indenture. These restrictions are subject to exceptions and qualifications, including that we can pay up to $175 million in dividends to stockholders in each fiscal year and we can pay dividends and make other restricted payments in an unlimited amount if our leverage ratio on a pro forma basis after giving effect to the dividend payment and other restricted payments would be less than or equal to 1.0:1.0.

Line of Credit Facility, Asset Restrictions				Borrowing availability under the Revolver is limited to a borrowing base which allows us to borrow up to 90% of the appraisal value of the inventory, in each case plus 90% of eligible credit card receivables, net of certain reserves. The borrowing base provides for borrowing up to 92.5% of the appraisal value during the fiscal months of August through October. Letters of credit reduce the amount available to borrow under the Revolver by an amount equal to the face value of the letters of credit.
Line of Credit Facility, Dividend Restrictions				Our ability to pay cash dividends, redeem options and repurchase shares is generally permitted, except under certain circumstances, including if either 1) excess availability under the Revolver is less than 30%, or is projected to be within 12 months after such payment or 2) excess availability under the Revolver is less than 15%, or is projected to be within 12 months after such payment, and the fixed charge coverage ratio, as calculated on a pro-forma basis for the prior 12 months is 1.1:1.0 or less.
Line of Credit Facility, Covenant Terms				In the event that excess availability under the Revolver is at any time less than the greater of (1) $30 million or (2) 10% of the lesser of the total commitment or the borrowing base, we will be subject to a fixed charge coverage ratio covenant of 1.0:1.0.

- Definition

The increases or decreases in lease payments that result from changes occurring after the inception of the lease in the factors (other than the passage of time) on which lease payments are based, except that any escalation of minimum lease payments relating to increases in construction or acquisition cost of the leased property or for increases in some measure of cost or value during the construction or preconstruction period, are excluded from contingent rentals. Contingent rentals also may include amounts for which the triggering events have not yet occurred or the specified targets for which have not yet been achieved (such as sales based percentage rent), but which events are considered probable of occurring or which specified targets are considered probable of being achieved.
