Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of Presentation The accompanying consolidated financial statements include the accounts of Under Armour, Inc. and its wholly owned subsidiaries (the “Company”). Certain information in footnote disclosures normally included in annual financial statements was condensed or omitted for the interim periods presented in accordance with the rules and regulations of the Securities and Exchange Commission (the “SEC”) and accounting principles generally accepted in the United States of America for interim consolidated financial statements. In the opinion of management, all adjustments consisting of normal, recurring adjustments considered necessary for a fair statement of the financial position and results of operations were included. Intercompany balances and transactions were eliminated. The consolidated balance sheet as of December 31, 2017 is derived from the audited financial statements included in the Company’s Annual Report on Form 10-K filed with the SEC for the year ended December 31, 2017 (the “ 2017 Form 10-K”), which should be read in conjunction with these consolidated financial statements. The results for the three months ended March 31, 2018, are not necessarily indicative of the results to be expected for the year ending December 31, 2018 or any other portions thereof. The Company identified an immaterial prior period error in the presentation of premium subscriptions in our Connected Fitness reporting segment. Subscription revenue was previously recorded net of any related commission. Beginning with the current period, subscription revenue is recorded on a gross basis and the related commission cost is included in selling, general and administrative expense in the consolidated statement of operations. The Company has revised the prior period to be consistent with the current period's presentation resulting in an increase in net revenues and selling, general and administrative expense of $2.5 million for the three months ended March 31, 2017. For the year ended December 31, 2017, the Company will record additional net revenue and SG&A expense of $12.7 million . The Company concluded that the error was not material to any of its previously issued financial statements. Cash, Cash Equivalents and Restricted Cash The Company considers all highly liquid investments with an original maturity of three months or less at date of inception to be cash and cash equivalents. The Company's restricted cash is reserved for payments for claims for its captive insurance program, which is included in prepaid expenses and other current assets on the Company's consolidated balance sheet. The following table provides a reconciliation of cash, cash equivalents and restricted cash reported within the consolidated balance sheet to the consolidated statement of cash flows. March 31, 2018 December 31, 2017 March 31, 2017 Cash and cash equivalents $ 283,644 $ 312,483 $ 172,128 Restricted cash 6,541 5,652 3,265 Total Cash, cash equivalents and restricted cash $ 290,185 $ 318,135 $ 175,393 Concentration of Credit Risk Financial instruments that subject the Company to significant concentration of credit risk consist primarily of accounts receivable. The majority of the Company’s accounts receivable is due from large retailers. Credit is extended based on an evaluation of each customer’s financial condition and collateral is not required. One of the Company's customers accounted for 11% , 12% and 17% of accounts receivable as of March 31, 2018 , December 31, 2017 and March 31, 2017 , respectively. For the three months ended March 31, 2018 and March 31, 2017 , no customer accounted for more than 10% of the Company's net revenues. Sale of Accounts Receivable During the first quarter of 2018, the Company entered into an agreement with an unaffiliated financial institution to sell selected accounts receivable on a recurring, non-recourse basis. Under this agreement, up to $150.0 million of the Company’s accounts receivable may be sold to the financial institution and remain outstanding at any point in time. The Company removes the sold accounts receivable from the consolidated balance sheets at the time of sale. The Company does not retain any interests in the sold accounts receivable. The Company acts as the collection agent for the outstanding accounts receivable on behalf of the financial institution. The carrying value of sold receivables approximated the fair value at March 31, 2018. During the first quarter of 2018, the Company sold total accounts receivable of $55.6 million . As of March 31, 2018, $55.6 million remained outstanding. The funding fee charged by the financial institution is included in the other expense, net line item in the consolidated statement of operations. Allowance for Doubtful Accounts As of March 31, 2018 , December 31, 2017 , and March 31, 2017 , the allowance for doubtful accounts was $19.8 million , $19.7 million and $12.4 million , respectively. Shipping and Handling Costs The Company charges certain customers shipping and handling fees. These fees are recorded in net revenues. The Company includes the majority of outbound handling costs as a component of selling, general and administrative expenses. Outbound handling costs include costs associated with preparing goods to ship to customers and certain costs to operate the Company’s distribution facilities. These costs, included within selling, general and administrative expenses, were $23.6 million and $24.7 million for the three months ended March 31, 2018 and 2017 , respectively. The Company includes outbound freight costs associated with shipping goods to customers as a component of cost of goods sold. Management Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates. Recently Issued Accounting Standards In January 2018, the FASB released guidance on the accounting for tax on the global intangible low-taxed income ("GILTI") provisions of the Tax Act. The GILTI provisions impose a tax on foreign income in excess of a deemed return on tangible assets of foreign corporations. The guidance indicates that either accounting for deferred taxes related to GILTI inclusions or to treat any taxes on GILTI inclusions as period costs are both acceptable methods subject to an accounting policy election. The Company has not yet made an accounting policy election in regards to the GILTI provisions under the Tax Act. The Company will make its GILTI accounting policy election during the one-year measurement period as allowed by the SEC. In accordance with the FASB guidance, until a policy election is made, any taxes related to GILTI inclusion are treated as period costs. Recently Adopted Accounting Standards In May 2014, the FASB issued ASU 2014-09, which supersedes the most current revenue recognition requirements. This ASU requires entities to recognize revenue in a way that depicts the transfer of goods or services to customers in an amount that reflects the consideration which the entity expects to be entitled to in exchange for those goods or services. The Company adopted the provisions under this ASU on January 1, 2018 on a modified retrospective basis resulting in a cumulative-effect benefit to retained earnings of $3.5 million as of the date of adoption, relating to revenues for certain wholesale and e-commerce sales being recognized upon shipment rather than upon delivery to the customer. Under this approach, the Company did not restate the prior financial statements presented. The provisions under this ASU were applied to all contracts at the date of initial adoptions. On the Company’s consolidated balance sheet, reserves for returns, allowances, discounts and markdowns will be included within customer refund liability, rather than accounts receivable, net, and the value of inventory associated with reserves for sales returns will be included within prepaid expenses and other current assets. On the Company’s consolidated statement of operations, certain costs associated with the Company’s customer support program for its wholesale customers will now be recorded in cost of goods sold. Additionally, certain free of charge product offered with a purchase will be recorded in cost of goods sold. Previously, both of these costs were recorded in selling, general and administrative expenses. Had the Company not adopted the provisions under this ASU, its consolidated balance sheet as of March 31, 2018 and its consolidated statement of operations and consolidated statement of cash flows for the three months ended March 31, 2018 would have been presented as follows: March 31, 2018 (As Presented) ASC 606 Adjustments March 31, 2018 (As Adjusted) Assets Current assets Cash and cash equivalents $ 283,644 $ — $ 283,644 Accounts receivable, net 805,413 (260,061 ) 545,352 Inventories 1,148,493 3,492 1,151,985 Prepaid expenses and other current assets 354,455 (96,766 ) 257,689 Total current assets 2,592,005 (353,335 ) 2,238,670 Non-current assets 1,672,314 1,703 1,674,017 Total assets $ 4,264,319 $ (351,632 ) $ 3,912,687 Liabilities and Stockholders’ Equity Current liabilities Revolving credit facility, current $ 135,000 $ — $ 135,000 Accounts payable 470,378 — 470,378 Accrued expenses 276,888 — 276,888 Customer refund liability 353,020 (353,020 ) — Current maturities of long term debt 27,000 — 27,000 Other current liabilities 54,771 5,688 60,459 Total current liabilities 1,317,057 (347,332 ) 969,725 Non-current liabilities 929,530 — 929,530 Total liabilities 2,246,587 (347,332 ) 1,899,255 Stockholders’ equity 2,017,732 (4,300 ) 2,013,432 Total liabilities and stockholders’ equity $ 4,264,319 $ (351,632 ) $ 3,912,687 March 31, 2018 (As Presented) ASC 606 Adjustments March 31, 2018 (As Adjusted) Net revenues $ 1,185,370 $ (1,853 ) $ 1,183,517 Cost of goods sold 661,917 (2,202 ) 659,715 Gross Profit 523,453 349 523,802 Selling, general and administrative expenses 514,634 1,456 516,090 Restructuring and impairment charges 37,480 — 37,480 Income (loss) from operations (28,661 ) (1,107 ) (29,768 ) Interest expense, net (8,564 ) — (8,564 ) Other income, net 2,888 — 2,888 Income (loss) before income taxes (34,337 ) (1,107 ) (35,444 ) Income tax expense (benefit) (4,093 ) (314 ) (4,407 ) Net loss $ (30,244 ) $ (793 ) $ (31,037 ) Basic net loss per share of Class A, B and C common stock $ (0.07 ) $ — $ (0.07 ) Diluted net loss per share of Class A, B and C common stock $ (0.07 ) $ — $ (0.07 ) March 31, 2018 (As Presented) ASC 606 Adjustments March 31, 2018 (As Adjusted) Cash flows from operating activities Net loss $ (30,244 ) $ (793 ) $ (31,037 ) Adjustments to reconcile net loss to net cash provided by (used) in operating activities — Depreciation and amortization 46,098 — 46,098 Unrealized foreign currency exchange rate gains (5,030 ) — (5,030 ) Loss on disposal of property and equipment 159 — 159 Impairment charges 2,248 — 2,248 Amortization of bond premium 63 — 63 Stock-based compensation 8,137 — 8,137 Excess tax deficiency from stock-based compensation arrangements — — — Deferred income taxes (10,645 ) (314 ) (10,959 ) Changes in reserves and allowances (251,194 ) 255,746 4,552 Changes in operating assets and liabilities: Accounts receivable 53,703 — 53,703 Inventories 16,697 — 16,697 Prepaid expenses and other assets (83,917 ) 95,206 11,289 Other non-current assets (731 ) — (731 ) Accounts payable (66,894 ) — (66,894 ) Accrued expenses and other liabilities (3,933 ) 467 (3,466 ) Customer refund liability 350,312 (350,312 ) — Income taxes payable and receivable (2,805 ) — (2,805 ) Net cash provided by operating activities 22,024 — 22,024 Cash flows from investing activities Net cash used in investing activities (55,930 ) — (55,930 ) Cash flows from financing activities Net cash provided by financing activities 3,799 — 3,799 Effect of exchange rate changes on cash, cash equivalents and restricted cash 2,157 — 2,157 Net decrease in cash, cash equivalents and restricted cash (27,950 ) — (27,950 ) Cash, cash equivalents and restricted cash Beginning of period 318,135 — 318,135 End of period $ 290,185 $ — $ 290,185 In January of 2016, the FASB issued ASU 2016-01 which simplifies the impairment assessment of equity investments. This ASU requires equity investments to be measured at fair value with changes recognized in net income unless they do not have readily determined fair values, in which case the cost basis measurement alternative may be elected. This ASU eliminates the requirement to disclose the methods and assumptions to estimate fair value for financial instruments, requires the use of the exit price for disclosure purposes, requires the change in liability due to a change in credit risk to be presented in other comprehensive income, requires separate presentation of financial assets and liabilities by measurement category and form of asset (securities and loans) and clarifies the need for a valuation allowance on a deferred tax asset related to available-for-sale securities. The Company adopted the provisions of this ASU on January 1, 2018 on a prospective basis. The Company elected to use the measurement alternative which allows the Company to measure its equity basis investments at historical cost, less any impairment, plus or minus changes resulting from observable price changes, resulting in no changes in the carrying value of its cost basis investments. In November 2016, the FASB issued ASU 2016-18, which reduced diversity in practice in the classification and presentation of changes in restricted cash on the statement of cash flows by including restricted cash and restricted cash equivalents with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The Company adopted the provisions under this ASU on January 1, 2018 on a retrospective basis. Revenue Recognition The Company recognizes revenue pursuant to Accounting Standards Codification 606 ("ASC 606"). Net revenues consist of both net sales, license and Connected Fitness revenue. Net sales are recognized upon transfer of control, including passage of title to the customer and transfer of risk of loss related to those goods. Payment is due in full when title is transferred. Transfer of title and risk of loss is based upon shipment under free on board shipping point for most goods or upon receipt by the customer depending on the country of the sale and the agreement with the customer. In some instances, transfer of title and risk of loss takes place at the point of sale, for example, at the Company’s brand and factory house stores. The Company may also ship product directly from its supplier to the customer and recognize revenue when the product is delivered to and accepted by the customer. License revenue is primarily recognized based upon shipment of licensed products sold by the Company's licensees. Sales taxes imposed on the Company’s revenues from product sales are presented on a net basis on the consolidated statements of income, and therefore do not impact net revenues or costs of goods sold. The Company records reductions to revenue for estimated customer returns, allowances, markdowns and discounts. The Company bases its estimates on historical rates of customer returns and allowances as well as the specific identification of outstanding returns, markdowns and allowances that have not yet been received by the Company. The actual amount of customer returns and allowances, which is inherently uncertain, may differ from the Company’s estimates. If the Company determines that actual or expected returns or allowances are significantly higher or lower than the reserves it established, it would record a reduction or increase, as appropriate, to net sales in the period in which it makes such a determination. Provisions for customer specific discounts are based on contractual obligations with certain major customers. Reserves for returns, allowances, markdowns and discounts are included within customer refund liability and the value of inventory associated with reserves for sales returns are included within prepaid expenses and other current assets on the consolidated balance sheet. Contract Liability Contract liability consists of payments received in advance of revenue recognition for subscriptions for our Connected Fitness applications and is included in other liabilities on the Company's consolidated balance sheet. As of March 31, 2018 and December, 31, 2017, contract liability was $25.7 million and $20.9 million , respectively. For the three months ended March 31, 2018, the Company recognized $9.6 million of revenue that was previously included in contract liability as of December 31, 2017. Commissions related to subscription revenue are capitalized and recognized over the subscription period. Practical Expedients and Policy Elections The Company has made a policy election to account for shipping and handling activities that occur after the customer has obtained control of a good as a fulfillment cost rather than an additional promised service. Additionally, the Company has elected not to disclose the value of unsatisfied performance obligations for subscriptions for our Connected Fitness applications as they have an original expected length of one year or less.

Restructuring and Related Activities [Abstract]
Restructuring	Restructuring and Impairment 2017 Restructuring Plan On July 27, 2017, the Company’s Board of Directors approved a restructuring plan (the “2017 restructuring plan”) to more closely align its financial resources with the critical priorities of the business. After completion of the 2017 restructuring plan, the Company recognized approximately $100.4 million of pre-tax charges in connection with this restructuring plan for the year ended December 31, 2017. In addition to these charges, the Company also recognized restructuring related goodwill impairment charges of approximately $28.6 million for its Connected Fitness business. 2018 Restructuring Plan On February 9, 2018, the Company's Board of Directors approved an additional restructuring plan (the "2018 restructuring plan") identifying further opportunities to optimize operations. In conjunction with this plan, approximately $110.0 to $130.0 million of pre-tax restructuring and related charges are expected to be incurred during the Company's 2018 fiscal year, including: • Up to $105.0 million in cash charges, consisting of up to: $55.0 million in facility and lease terminations and $50.0 million in contract termination and other restructuring charges; and, • Up to $25.0 million in non-cash charges comprised of approximately $10.0 million of inventory related charges and approximately $15.0 million of intangibles and other asset related impairments. The summary of the costs incurred during the three months ended March 31, 2018 in connection with the 2018 restructuring plan are as follows: Restructuring and Impairment Charges Incurred Estimated Restructuring and Impairment Charges to be Incurred (In thousands) Three Months Ended March 31, 2018 Nine Months Ending December 31, 2018 (1) Year Ending December 31, 2018 (1) Costs recorded in cost of goods sold: Inventory write-offs $ 7,474 $ 2,500 $ 9,974 Total costs recorded in cost of goods sold 7,474 2,500 9,974 Costs recorded in restructuring and impairment charges: Property and equipment impairment 2,248 13,000 15,248 Other restructuring related costs 9,882 12,000 21,882 Contract exit costs 25,350 55,000 80,350 Total costs recorded in restructuring and impairment charges 37,480 80,000 117,480 Total restructuring, impairment and restructuring related costs $ 44,954 $ 82,500 $ 127,454 (1) Estimated restructuring and impairment charges to be incurred reflect the high-end of the range of the estimated remaining charges expected to be taken by the Company during 2018 in connection with the restructuring plan.

Long Term Debt

Long Term Debt	3 Months Ended

Debt Disclosure [Abstract]
Long Term Debt	Long Term Debt Credit Facility The Company is party to a credit agreement that provides revolving credit commitments for up to $1.25 billion of borrowings, as well as term loan commitments, in each case maturing in January 2021 . As of March 31, 2018 , there was $135.0 million outstanding under the revolving credit facility and $155.0 million of term loan borrowings outstanding. At the Company's request and the lender's consent, revolving and or term loan borrowings may be increased by up to $300.0 million in aggregate, subject to certain conditions as set forth in the credit agreement, as amended. Incremental borrowings are uncommitted and the availability thereof will depend on market conditions at the time the Company seeks to incur such borrowings. The borrowings under the revolving credit facility have maturities of less than one year. Up to $50.0 million of the facility may be used for the issuance of letters of credit. There were $4.5 million of letters of credit outstanding as of March 31, 2018 . The credit agreement contains negative covenants that, subject to significant exceptions, limit the ability of the Company and its subsidiaries to, among other things, incur additional indebtedness, make restricted payments, pledge their assets as security, make investments, loans, advances, guarantees and acquisitions, undergo fundamental changes and enter into transactions with affiliates. The Company is also required to maintain a ratio of consolidated EBITDA, as defined in the credit agreement, to consolidated interest expense of not less than 3.50 to 1.00 and is not permitted to allow the ratio of consolidated total indebtedness to consolidated EBITDA to be greater than 3.25 to 1.00 ("consolidated leverage ratio"). In February 2018, the Company amended the credit agreement to amend the definition of consolidated EBITDA, and to provide that the Company's trailing four-quarter consolidated leverage ratio may not exceed 3.75 to 1.00 for the four quarters ending June 30, 2018, and 4.00 to 1.00 for the four quarters ending September 30, 3018. Beginning with the four quarters ending December 31, 2018 and thereafter, the consolidated leverage ratio requirement will return to 3.25 to 1.00. As of March 31, 2018 , the Company was in compliance with these ratios. In addition, the credit agreement contains events of default that are customary for a facility of this nature, and includes a cross default provision whereby an event of default under other material indebtedness, as defined in the credit agreement, will be considered an event of default under the credit agreement. Borrowings under the credit agreement bear interest at a rate per annum equal to, at the Company’s option, either (a) an alternate base rate, or (b) a rate based on the rates applicable for deposits in the interbank market for U.S. Dollars or the applicable currency in which the loans are made (“adjusted LIBOR”), plus in each case an applicable margin. The applicable margin for loans will be adjusted by reference to a grid (the “Pricing Grid”) based on the consolidated leverage ratio and ranges between 1.00% to 1.25% for adjusted LIBOR loans and 0.00% to 0.25% for alternate base rate loans. The weighted average interest rates under the outstanding term loans and revolving credit facility borrowings were 2.8% and 1.9% during the three months ended March 31, 2018 and 2017 , respectively. The Company pays a commitment fee on the average daily unused amount of the revolving credit facility and certain fees with respect to letters of credit. As of March 31, 2018 , the commitment fee was 15.0 basis points. Since inception, the Company incurred and deferred $3.9 million in financing costs in connection with the credit agreement. 3.250% Senior Notes In June 2016, the Company issued $600.0 million aggregate principal amount of 3.250% senior unsecured notes due June 15, 2026 (the “Notes”). The proceeds were used to pay down amounts outstanding under the revolving credit facility. Interest is payable semi-annually on June 15 and December 15 beginning December 15, 2016. Prior to March 15, 2026 (three months prior to the maturity date of the Notes), the Company may redeem some or all of the Notes at any time or from time to time at a redemption price equal to the greater of 100% of the principal amount of the Notes to be redeemed or a “make-whole” amount applicable to such Notes as described in the indenture governing the Notes, plus accrued and unpaid interest to, but excluding, the redemption date. On or after March 15, 2026 (three months prior to the maturity date of the Notes), the Company may redeem some or all of the Notes at any time or from time to time at a redemption price equal to 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest to, but excluding, the redemption date. The indenture governing the Notes contains covenants, including limitations that restrict the Company’s ability and the ability of certain of its subsidiaries to create or incur secured indebtedness and enter into sale and leaseback transactions and the Company’s ability to consolidate, merge or transfer all or substantially all of its properties or assets to another person, in each case subject to material exceptions described in the indenture. The Company incurred and deferred $5.3 million in financing costs in connection with the Notes. Other Long Term Debt In December 2012, the Company entered into a $50.0 million recourse loan collateralized by the land, buildings and tenant improvements comprising the Company's corporate headquarters. The loan has a seven year term and maturity date of December 2019 . The loan bears interest at one month LIBOR plus a margin of 1.50% , and allows for prepayment without penalty. The loan includes covenants and events of default substantially consistent with the Company's credit agreement discussed above. The loan also requires prior approval of the lender for certain matters related to the property, including transfers of any interest in the property. As of March 31, 2018 , December 31, 2017 and March 31, 2017 , the outstanding balance on the loan was $39.5 million , $40.0 million and $41.5 million , respectively. The weighted average interest rate on the loan was 3.1% and 2.3% for the three months ended March 31, 2018 and 2017, respectively. Interest expense, net, was $8.6 million and $7.8 million for the three months ended March 31, 2018 and 2017 , respectively. Interest expense includes the amortization of deferred financing costs, bank fees, capital and built-to-suit lease interest and interest expense under the credit and other long term debt facilities . The Company monitor s the financial health and stability of its lenders under the credit and other long term debt facilities, however during any period of significant instability in the credit markets, lenders could be negatively impacted in their ability to perform under these facilities.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies There were no significant changes to the contractual obligations reported in the 2017 Form 10-K other than those which occur in the normal course of business. In connection with various contracts and agreements, the Company has agreed to indemnify counterparties against certain third party claims relating to the infringement of intellectual property rights and other items. Generally, such indemnification obligations do not apply in situations in which the counterparties are grossly negligent, engage in willful misconduct, or act in bad faith. Based on the Company’s historical experience and the estimated probability of future loss, the Company has determined that the fair value of such indemnifications is not material to its consolidated financial position or results of operations. From time to time, the Company is involved in litigation and other proceedings, including matters related to commercial and intellectual property disputes, as well as trade, regulatory and other claims related to its business. Other than as described below, the Company believes that all current proceedings are routine in nature and incidental to the conduct of its business, and that the ultimate resolution of any such proceedings will not have a material adverse effect on its consolidated financial position, results of operations or cash flows. Securities Class Action On March 23, 2017, three separate securities cases previously filed against the Company in the United States District Court for the District of Maryland (the “Court”) were consolidated under the caption In re Under Armour Securities Litigation , Case No. 17-cv-00388-RDB (the “Consolidated Action”). On August 4, 2017, the lead plaintiff in the Consolidated Action, North East Scotland Pension Fund, joined by named plaintiff Bucks County Employees Retirement Fund, filed a consolidated amended complaint (the “Amended Complaint”) against the Company, the Company’s Chief Executive Officer and former Chief Financial Officers, Lawrence Molloy and Brad Dickerson. The Amended Complaint alleges violations of Section 10(b) (and Rule 10b-5) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) and Section 20(a) control person liability under the Exchange Act against the officers named in the Amended Complaint, claiming that the defendants made material misstatements and omissions regarding, among other things, the Company's growth and consumer demand for certain of the Company's products. The class period identified in the Amended Complaint is September 16, 2015 through January 30, 2017. The Amended Complaint also asserts claims under Sections 11 and 15 of the Securities Act of 1933, as amended (the “Securities Act”), in connection with the Company’s public offering of senior unsecured notes in June 2016. The Securities Act claims are asserted against the Company, the Company’s Chief Executive Officer, Mr. Molloy, the Company’s directors who signed the registration statement pursuant to which the offering was made and the underwriters that participated in the offering. The Amended Complaint alleges that the offering materials utilized in connection with the offering contained false and/or misleading statements and omissions regarding, among other things, the Company’s growth and consumer demand for certain of the Company’s products. On November 9, 2017, the Company and the other defendants filed a motion to dismiss the Amended Complaint, which is still pending with the Court. The Company believes that the claims asserted in the Consolidated Action are without merit and intends to defend the lawsuit vigorously. However, because of the inherent uncertainty as to the outcome of this proceeding, the Company is unable at this time to estimate the possible impact of the outcome of this matter. Derivative Complaints In April 2018, two purported stockholders filed separate stockholder derivative complaints in the United States District Court for the District of Maryland (the “Derivative Complaints”). The Derivative Complaints were brought against Kevin Plank (the Company’s Chairman and Chief Executive Officer) and certain other members of the Company’s Board of Directors and name the Company as a nominal defendant. The Derivative Complaints make allegations related to the Company’s purchase of certain parcels of land from entities controlled by Mr. Plank (through Sagamore Development Company, LLC ("Sagamore")), as well as other alleged related party transactions. Sagamore purchased these parcels in 2014. Its total investment in the parcels was approximately $72.0 million , which included the initial $35.0 million purchase price for the property, an additional $30.6 million to terminate a lease encumbering the property and approximately $6.4 million of development costs. As previously disclosed, in June 2016, the Company purchased the unencumbered parcels for $70.3 million in order to further expand the Company’s corporate headquarters to accommodate its growth needs. The Company negotiated a purchase price for the parcels that it determined represented the fair market value of the parcels and approximated the cost to the seller to purchase and develop the parcels. In connection with its evaluation of the potential purchase, the Company engaged an independent third-party to appraise the fair market value of the parcels, and the Audit Committee of the Company’s Board of Directors engaged its own independent appraisal firm to assess the parcels. The Audit Committee determined that the terms of the purchase were reasonable and fair, and the transaction was approved by the Audit Committee in accordance with the Company’s policy on transactions with related persons. In Mioduszewski v. Plank, et al. , filed on April 16, 2018, the complaint asserts that Mr. Plank and the director defendants breached their fiduciary duties in connection with the purchase of the parcels and other alleged related party transactions and that the director defendants aided and abetted Mr. Plank’s alleged breach of his fiduciary duties. The complaint also asserts an unjust enrichment claim against Mr. Plank. The complaint seeks damages on behalf of the Company and certain corporate governance-related actions. In King v. Plank, et al. , filed on April 30, 2018, the complaint asserts similar breach of fiduciary duty claims against Mr. Plank and the director defendants and also claims that Sagamore aided and abetted the alleged breaches of fiduciary duty by the other defendants in connection with Sagamore’s alleged role in the sale of the parcels of land to the Company. The King complaint also asserts an unjust enrichment claim against Mr. Plank and Sagamore. It asserts similar damages to the damages sought in the Mioduszewski complaint. Prior to the filing of the Derivative Complaints, each of the purported stockholders had sent the Company a letter demanding that the Company pursue claims similar to the claims asserted in the Derivative Complaints. Following an investigation, a majority of disinterested and independent directors of the Company determined that the claims should not be pursued by the Company and informed each of these purported stockholders of that determination. The Company believes that the claims asserted in the Derivative Complaints are without merit and intends to defend these matters vigorously. However, because of the inherent uncertainty as to the outcome of these proceedings, the Company is unable at this time to estimate the possible impact of the outcome of these matters. Data Incident As previously disclosed, during the quarter ended March 31, 2018 an unauthorized third party acquired data associated with the Company’s Connected Fitness users’ accounts for the Company’s MyFitnessPal application and website. A consumer class action lawsuit has been filed against the Company in connection with this incident, and the Company has received inquiries regarding the incident from certain government regulators and agencies. The Company does not currently consider these matters to be material and believes its insurance coverage will provide coverage should any significant expense arise.

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (an exit price). The fair value accounting guidance outlines a valuation framework, creates a fair value hierarchy in order to increase the consistency and comparability of fair value measurements and the related disclosures, and prioritizes the inputs used in measuring fair value as follows: Level 1: Observable inputs such as quoted prices in active markets; Level 2: Inputs, other than quoted prices in active markets, that are observable either directly or indirectly; and Level 3: Unobservable inputs for which there is little or no market data, which require the reporting entity to develop its own assumptions. Financial assets and (liabilities) measured at fair value are set forth in the table below: March 31, 2018 December 31, 2017 March 31, 2017 (In thousands) Level 1 Level 2 Level 3 Level 1 Level 2 Level 3 Level 1 Level 2 Level 3 Derivative foreign currency contracts (see Note 8) (7,293 ) — (6,818 ) — — 5,801 — Interest rate swap contracts (see Note 8) — 2,103 — — 1,088 — — 162 — TOLI policies held by the Rabbi Trust — 5,692 — — 5,756 — — 5,106 — Deferred Compensation Plan obligations — (8,123 ) — — (7,971 ) — — (8,152 ) — Fair values of the financial assets and liabilities listed above are determined using inputs that use as their basis readily observable market data that are actively quoted and are validated through external sources, including third-party pricing services and brokers. The foreign currency contracts represent gains and losses on derivative contracts, which is the net difference between the U.S. dollar value to be received or paid at the contracts’ settlement date and the U.S. dollar value of the foreign currency to be sold or purchased at the current market exchange rate. The interest rate swap contracts represent gains and losses on the derivative contracts, which is the net difference between the fixed interest to be paid and variable interest to be received over the term of the contract based on current market rates. The fair value of the trust owned life insurance (“TOLI”) policies held by the Rabbi Trust is based on the cash-surrender value of the life insurance policies, which are invested primarily in mutual funds and a separately managed fixed income fund. These investments are initially made in the same funds and purchased in substantially the same amounts as the selected investments of participants in the Under Armour, Inc. Deferred Compensation Plan (the “Deferred Compensation Plan”), which represent the underlying liabilities to participants in the Deferred Compensation Plan. Liabilities under the Deferred Compensation Plan are recorded at amounts due to participants, based on the fair value of participants’ selected investments. As of March 31, 2018 , December 31, 2017 and March 31, 2017 , the fair value of the Company's Senior Notes was $532.2 million , $526.3 million and $548.2 million , respectively. The carrying value of the Company's other long term debt approximated its fair value as of March 31, 2018 , December 31, 2017 and March 31, 2017 . The fair value of long-term debt is estimated based upon quoted prices for similar instruments or quoted prices for identical instruments in inactive markets (Level 2). Some assets are not measured at fair value on an ongoing basis but are subject to fair value adjustments only in certain circumstances. These assets can include long-lived assets and goodwill that have been reduced to fair value when impaired. Assets that are written down to fair value when impaired are not subsequently adjusted to fair value unless further impairment occurs.

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Performance Based Equity Compensation	Performance Based Equity Compensation The Company grants a combination of time-based and performance-based restricted stock units and stock options as part of its incentive compensation. Certain senior executives are eligible to receive performance-based awards. During the three months ended March 31, 2018 , 0.8 million performance-based restricted stock units and 0.3 million performance-based stock options for shares of our Class C common stock were awarded under the Company's Second Amended and Restated 2005 Omnibus Long-Term Incentive Plan, as amended. The performance-based restricted stock units and options have weighted average grant date fair values of $15.41 and $6.91 , respectively, and have vesting conditions tied to the achievement of an operating income target for 2018. Upon the achievement of the target, one fourth of the restricted stock units and options will vest each in February 2019 , 2020, 2021 and 2022 . During 2017, the Company granted performance-based restricted stock units and options with vesting conditions tied to the achievement of certain combined annual revenue and operating income targets for 2017 and 2018. As of March 31, 2018 , the Company deemed the achievement of these targets improbable. As such, no expense for these awards has been recorded during the three months ended March 31, 2018.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Risk Management and Derivatives	Risk Management and Derivatives Foreign Currency Risk Management The Company is exposed to gains and losses resulting from fluctuations in foreign currency exchange rates relating to transactions generated by its international subsidiaries in currencies other than their local currencies. These gains and losses are primarily driven by intercompany transactions and inventory purchases denominated in currencies other than the functional currency of the purchasing entity. From time to time, the Company may elect to enter into foreign currency contracts to reduce the risk associated with foreign currency exchange rate fluctuations on intercompany transactions and projected inventory purchases for its international subsidiaries. As of March 31, 2018 , the aggregate notional value of the Company's outstanding foreign currency contracts was $751.7 million , which was comprised of Canadian Dollar/U.S. Dollar, Euro/U.S. Dollar, Yen/Euro, Mexican Peso/Euro and Pound Sterling/Euro currency pairs with contract maturities ranging from one to thirteen months . A portion of the Company's foreign currency contracts are not designated as cash flow hedges, and accordingly, changes in their fair value are recorded in earnings. The Company also enters into foreign currency contracts designated as cash flow hedges. For foreign currency contracts designated as cash flow hedges, changes in fair value, excluding any ineffective portion, are recorded in other comprehensive income until net income is affected by the variability in cash flows of the hedged transaction. The effective portion is generally released to net income after the maturity of the related derivative and is classified in the same manner as the underlying exposure. During the three months ended March 31, 2018 and 2017 , the Company reclassified $2.0 million and $0.8 million from other comprehensive income to cost of goods sold related to foreign currency contracts designated as cash flow hedges, respectively. The fair values of the Company's foreign currency contracts were liabilities of $7.3 million and $6.8 million as of March 31, 2018 and December 31, 2017 , respectively, and were included in other current liabilities on the consolidated balance sheet. The fair value of the Company's foreign currency contracts was an asset of $5.8 million as of March 31, 2017 , and were included in prepaid expenses and other current assets on the consolidated balance sheet. Refer to Note 6 for a discussion of the fair value measurements. Included in other income, net were the following amounts related to changes in foreign currency exchange rates and derivative foreign currency contracts: Three Months Ended March 31, (In thousands) 2018 2017 Unrealized foreign currency exchange rate gains (losses) $ (5,030 ) $ 8,313 Realized foreign currency exchange rate gains (losses) (2,374 ) (272 ) Unrealized derivative gains (losses) 35 (704 ) Realized derivative gains (losses) 4,226 (6,366 ) Interest Rate Risk Management In order to maintain liquidity and fund business operations, the Company enters into long term debt arrangements with various lenders which bear a range of fixed and variable rates of interest. The nature and amount of the Company's long term debt can be expected to vary as a result of future business requirements, market conditions and other factors. The Company may elect to enter into interest rate swap contracts to reduce the impact associated with interest rate fluctuations. The Company utilizes interest rate swap contracts to convert a portion of variable rate debt to fixed rate debt. The contracts pay fixed and receive variable rates of interest. The interest rate swap contracts are accounted for as cash flow hedges. Accordingly, the effective portion of the changes in their fair value are recorded in other comprehensive income and reclassified into interest expense over the life of the underlying debt obligation. Refer to Note 4 for a discussion of long term debt. As of March 31, 2018 , the notional value of the Company's outstanding interest rate swap contracts was $131.3 million . During the three months ended March 31, 2018 and 2017 , the Company recorded a $22.7 thousand and $349.4 thousand increase in interest expense, respectively, representing the effective portion of the contract reclassified from accumulated other comprehensive income. The fair values of the interest rate swap contracts were assets of $2.1 million , $1.1 million , and $0.2 million as of March 31, 2018 , December 31, 2017 , and March 31, 2017 , respectively, and were included in other long term assets on the consolidated balance sheet. The Company enters into derivative contracts with major financial institutions with investment grade credit ratings and is exposed to credit losses in the event of non-performance by these financial institutions. This credit risk is generally limited to the unrealized gains in the derivative contracts. However, the Company monitors the credit quality of these financial institutions and considers the risk of counterparty default to be minimal.

Income Tax Disclosure [Abstract]
Provision for Income Taxes	Provision for Income Taxes The effective rates for income taxes were 11.9% and 199.5% for the three months ended March 31, 2018 and 2017 , respectively. The effective tax rate for the three months ended March 31, 2018 was lower than the effective tax rate for the three months ended March 31, 2017 , primarily due to pre-tax losses which are partially offset by the recording of certain valuation allowances and shortfalls from the share based compensation in 2018. On December 22, 2017, the Tax Cuts and Jobs Act (the “Tax Act”) was enacted in the United States. The Company recognized the income tax effects of the Tax Act in its 2017 financial statements in accordance with Staff Accounting Bulletin 118, which provides SEC staff guidance for the application of ASC Topic 740, Income Taxes, in the reporting period in which the Tax Act was signed into law. As noted in its 2017 audited consolidated financial statements, the Company was able to reasonably estimate certain effects and, therefore, recorded provisional amounts associated with the one-time transition tax on indefinitely reinvested foreign earnings and the adjustment to our deferred tax assets and liabilities for the reduction in the corporate income tax rate. The Company did not identify items for which the income tax effects of the Tax Act have not been completed and a reasonable estimate could not be determined. The Company has not made any additional measurement period adjustments related to these items during the three months ended March 31, 2018. As the Company continues its analysis of the Tax Act, reviews all information, collects and prepares necessary data and interprets any additional guidance, it may make adjustments to the provisional amounts that have been recorded that may materially impact the Company's provision for income taxes. Any subsequent adjustment will be recorded to current income tax expense when the analysis is completed. The Company evaluates on a quarterly basis whether its deferred tax assets are realizable which requires significant judgment. The Company considers all available positive and negative evidence, including historical operating performance and expectations of future operating performance. To the extent the Company believes it is more likely than not that all or some portion of the asset will not be realized, valuation allowances are established against deferred tax assets, which increase income tax expense in the period when such a determination is made. A significant portion of the Company's deferred tax assets relate to U.S. federal and state taxing jurisdictions. Realization of these deferred tax assets is dependent on future U.S. pre-tax earnings. Due to its challenged U.S. results, the Company incurred significant net operating losses (“NOLs”) in these jurisdictions in 2017 and continued losses during the three months ended March 31, 2018. The Company continues to believe that the weight of the positive evidence outweighs the negative evidence regarding the realization of the majority of the net deferred tax assets related to U.S. federal and state taxing jurisdictions. However, consistent with prior periods, valuation allowances have been recorded against select U.S. State and foreign net operating losses.

Due to the Company being in a net loss position for the three months ended March 31, 2018 and 2017, there were no warrants, stock options, or restricted stock units included in the computation of diluted earnings per share, as their effect would have been anti-dilutive.

Segment Reporting [Abstract]
Segment Data and Related Information	Segment Data and Related Information The Company’s operating segments are based on how the Chief Operating Decision Maker (“CODM”) makes decisions about allocating resources and assessing performance. As such, the CODM receives discrete financial information for the Company's principal business by geographic region based on the Company’s strategy to become a global brand. These geographic regions include North America, Latin America, Europe, the Middle East and Africa (“EMEA”), and Asia-Pacific. Each geographic segment operates exclusively in one industry: the development, marketing and distribution of branded performance apparel, footwear and accessories. The CODM also receives discrete financial information for the Company's Connected Fitness business. Total expenditures for additions to long-lived assets are not disclosed as this information is not regularly provided to the CODM. The net revenues and operating income (loss) associated with the Company's segments are summarized in the following tables. Net revenues represent sales to external customers for each segment. Intercompany balances were eliminated for separate disclosure. The majority of corporate service costs within North America have not been allocated to the Company's other segments.

Subsequent Events [Abstract]
Subsequent Events	Subsequent Events On April 23, 2018, the Company invested ¥ 41.7 billion or $38.4 million in exchange for an additional 10% common stock ownership in Dome Corporation (“Dome”), the Company’s Japanese licensee. This additional investment brings the Company’s total investment to 29.5% of Dome’s common stock from 19.5% . This investment is subject to foreign currency translation rate fluctuations as it is held by the Company’s European subsidiary. The Company will account for its investment in Dome under the equity method given that it has the ability to exercise significant influence, resulting in an allocable share of Dome’s net income recorded on our consolidated statement of operations, which we do not expect to be material.

Summary of Significant Accoun20

Summary of Significant Accounting Policies (Policies)	3 Months Ended
	Mar. 31, 2018
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying consolidated financial statements include the accounts of Under Armour, Inc. and its wholly owned subsidiaries (the “Company”). Certain information in footnote disclosures normally included in annual financial statements was condensed or omitted for the interim periods presented in accordance with the rules and regulations of the Securities and Exchange Commission (the “SEC”) and accounting principles generally accepted in the United States of America for interim consolidated financial statements. In the opinion of management, all adjustments consisting of normal, recurring adjustments considered necessary for a fair statement of the financial position and results of operations were included. Intercompany balances and transactions were eliminated. The consolidated balance sheet as of December 31, 2017 is derived from the audited financial statements included in the Company’s Annual Report on Form 10-K filed with the SEC for the year ended December 31, 2017 (the “ 2017 Form 10-K”), which should be read in conjunction with these consolidated financial statements. The results for the three months ended March 31, 2018, are not necessarily indicative of the results to be expected for the year ending December 31, 2018 or any other portions thereof. The Company identified an immaterial prior period error in the presentation of premium subscriptions in our Connected Fitness reporting segment. Subscription revenue was previously recorded net of any related commission. Beginning with the current period, subscription revenue is recorded on a gross basis and the related commission cost is included in selling, general and administrative expense in the consolidated statement of operations. The Company has revised the prior period to be consistent with the current period's presentation resulting in an increase in net revenues and selling, general and administrative expense of $2.5 million for the three months ended March 31, 2017. For the year ended December 31, 2017, the Company will record additional net revenue and SG&A expense of $12.7 million . The Company concluded that the error was not material to any of its previously issued financial statements.
Cash, Cash Equivalents and Restricted Cash	Cash, Cash Equivalents and Restricted Cash The Company considers all highly liquid investments with an original maturity of three months or less at date of inception to be cash and cash equivalents. The Company's restricted cash is reserved for payments for claims for its captive insurance program, which is included in prepaid expenses and other current assets on the Company's consolidated balance sheet.
Concentration of Credit Risk	Concentration of Credit Risk Financial instruments that subject the Company to significant concentration of credit risk consist primarily of accounts receivable. The majority of the Company’s accounts receivable is due from large retailers. Credit is extended based on an evaluation of each customer’s financial condition and collateral is not required.
Sale of Accounts Receivable/Allowance For Doubtful Accounts	Sale of Accounts Receivable During the first quarter of 2018, the Company entered into an agreement with an unaffiliated financial institution to sell selected accounts receivable on a recurring, non-recourse basis. Under this agreement, up to $150.0 million of the Company’s accounts receivable may be sold to the financial institution and remain outstanding at any point in time. The Company removes the sold accounts receivable from the consolidated balance sheets at the time of sale. The Company does not retain any interests in the sold accounts receivable. The Company acts as the collection agent for the outstanding accounts receivable on behalf of the financial institution.
Shipping and Handling Costs	Shipping and Handling Costs The Company charges certain customers shipping and handling fees. These fees are recorded in net revenues. The Company includes the majority of outbound handling costs as a component of selling, general and administrative expenses. Outbound handling costs include costs associated with preparing goods to ship to customers and certain costs to operate the Company’s distribution facilities. These costs, included within selling, general and administrative expenses, were $23.6 million and $24.7 million for the three months ended March 31, 2018 and 2017 , respectively. The Company includes outbound freight costs associated with shipping goods to customers as a component of cost of goods sold.
Management Estimates	Management Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates.
Recently Issued Accounting Standards/Recently Adopted Accounting Standards	Recently Issued Accounting Standards In January 2018, the FASB released guidance on the accounting for tax on the global intangible low-taxed income ("GILTI") provisions of the Tax Act. The GILTI provisions impose a tax on foreign income in excess of a deemed return on tangible assets of foreign corporations. The guidance indicates that either accounting for deferred taxes related to GILTI inclusions or to treat any taxes on GILTI inclusions as period costs are both acceptable methods subject to an accounting policy election. The Company has not yet made an accounting policy election in regards to the GILTI provisions under the Tax Act. The Company will make its GILTI accounting policy election during the one-year measurement period as allowed by the SEC. In accordance with the FASB guidance, until a policy election is made, any taxes related to GILTI inclusion are treated as period costs. Recently Adopted Accounting Standards In May 2014, the FASB issued ASU 2014-09, which supersedes the most current revenue recognition requirements. This ASU requires entities to recognize revenue in a way that depicts the transfer of goods or services to customers in an amount that reflects the consideration which the entity expects to be entitled to in exchange for those goods or services. The Company adopted the provisions under this ASU on January 1, 2018 on a modified retrospective basis resulting in a cumulative-effect benefit to retained earnings of $3.5 million as of the date of adoption, relating to revenues for certain wholesale and e-commerce sales being recognized upon shipment rather than upon delivery to the customer. Under this approach, the Company did not restate the prior financial statements presented. The provisions under this ASU were applied to all contracts at the date of initial adoptions. On the Company’s consolidated balance sheet, reserves for returns, allowances, discounts and markdowns will be included within customer refund liability, rather than accounts receivable, net, and the value of inventory associated with reserves for sales returns will be included within prepaid expenses and other current assets. On the Company’s consolidated statement of operations, certain costs associated with the Company’s customer support program for its wholesale customers will now be recorded in cost of goods sold. Additionally, certain free of charge product offered with a purchase will be recorded in cost of goods sold. Previously, both of these costs were recorded in selling, general and administrative expenses. Had the Company not adopted the provisions under this ASU, its consolidated balance sheet as of March 31, 2018 and its consolidated statement of operations and consolidated statement of cash flows for the three months ended March 31, 2018 would have been presented as follows: March 31, 2018 (As Presented) ASC 606 Adjustments March 31, 2018 (As Adjusted) Assets Current assets Cash and cash equivalents $ 283,644 $ — $ 283,644 Accounts receivable, net 805,413 (260,061 ) 545,352 Inventories 1,148,493 3,492 1,151,985 Prepaid expenses and other current assets 354,455 (96,766 ) 257,689 Total current assets 2,592,005 (353,335 ) 2,238,670 Non-current assets 1,672,314 1,703 1,674,017 Total assets $ 4,264,319 $ (351,632 ) $ 3,912,687 Liabilities and Stockholders’ Equity Current liabilities Revolving credit facility, current $ 135,000 $ — $ 135,000 Accounts payable 470,378 — 470,378 Accrued expenses 276,888 — 276,888 Customer refund liability 353,020 (353,020 ) — Current maturities of long term debt 27,000 — 27,000 Other current liabilities 54,771 5,688 60,459 Total current liabilities 1,317,057 (347,332 ) 969,725 Non-current liabilities 929,530 — 929,530 Total liabilities 2,246,587 (347,332 ) 1,899,255 Stockholders’ equity 2,017,732 (4,300 ) 2,013,432 Total liabilities and stockholders’ equity $ 4,264,319 $ (351,632 ) $ 3,912,687 March 31, 2018 (As Presented) ASC 606 Adjustments March 31, 2018 (As Adjusted) Net revenues $ 1,185,370 $ (1,853 ) $ 1,183,517 Cost of goods sold 661,917 (2,202 ) 659,715 Gross Profit 523,453 349 523,802 Selling, general and administrative expenses 514,634 1,456 516,090 Restructuring and impairment charges 37,480 — 37,480 Income (loss) from operations (28,661 ) (1,107 ) (29,768 ) Interest expense, net (8,564 ) — (8,564 ) Other income, net 2,888 — 2,888 Income (loss) before income taxes (34,337 ) (1,107 ) (35,444 ) Income tax expense (benefit) (4,093 ) (314 ) (4,407 ) Net loss $ (30,244 ) $ (793 ) $ (31,037 ) Basic net loss per share of Class A, B and C common stock $ (0.07 ) $ — $ (0.07 ) Diluted net loss per share of Class A, B and C common stock $ (0.07 ) $ — $ (0.07 ) March 31, 2018 (As Presented) ASC 606 Adjustments March 31, 2018 (As Adjusted) Cash flows from operating activities Net loss $ (30,244 ) $ (793 ) $ (31,037 ) Adjustments to reconcile net loss to net cash provided by (used) in operating activities — Depreciation and amortization 46,098 — 46,098 Unrealized foreign currency exchange rate gains (5,030 ) — (5,030 ) Loss on disposal of property and equipment 159 — 159 Impairment charges 2,248 — 2,248 Amortization of bond premium 63 — 63 Stock-based compensation 8,137 — 8,137 Excess tax deficiency from stock-based compensation arrangements — — — Deferred income taxes (10,645 ) (314 ) (10,959 ) Changes in reserves and allowances (251,194 ) 255,746 4,552 Changes in operating assets and liabilities: Accounts receivable 53,703 — 53,703 Inventories 16,697 — 16,697 Prepaid expenses and other assets (83,917 ) 95,206 11,289 Other non-current assets (731 ) — (731 ) Accounts payable (66,894 ) — (66,894 ) Accrued expenses and other liabilities (3,933 ) 467 (3,466 ) Customer refund liability 350,312 (350,312 ) — Income taxes payable and receivable (2,805 ) — (2,805 ) Net cash provided by operating activities 22,024 — 22,024 Cash flows from investing activities Net cash used in investing activities (55,930 ) — (55,930 ) Cash flows from financing activities Net cash provided by financing activities 3,799 — 3,799 Effect of exchange rate changes on cash, cash equivalents and restricted cash 2,157 — 2,157 Net decrease in cash, cash equivalents and restricted cash (27,950 ) — (27,950 ) Cash, cash equivalents and restricted cash Beginning of period 318,135 — 318,135 End of period $ 290,185 $ — $ 290,185 In January of 2016, the FASB issued ASU 2016-01 which simplifies the impairment assessment of equity investments. This ASU requires equity investments to be measured at fair value with changes recognized in net income unless they do not have readily determined fair values, in which case the cost basis measurement alternative may be elected. This ASU eliminates the requirement to disclose the methods and assumptions to estimate fair value for financial instruments, requires the use of the exit price for disclosure purposes, requires the change in liability due to a change in credit risk to be presented in other comprehensive income, requires separate presentation of financial assets and liabilities by measurement category and form of asset (securities and loans) and clarifies the need for a valuation allowance on a deferred tax asset related to available-for-sale securities. The Company adopted the provisions of this ASU on January 1, 2018 on a prospective basis. The Company elected to use the measurement alternative which allows the Company to measure its equity basis investments at historical cost, less any impairment, plus or minus changes resulting from observable price changes, resulting in no changes in the carrying value of its cost basis investments. In November 2016, the FASB issued ASU 2016-18, which reduced diversity in practice in the classification and presentation of changes in restricted cash on the statement of cash flows by including restricted cash and restricted cash equivalents with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The Company adopted the provisions under this ASU on January 1, 2018 on a retrospective basis.
