Accounting Policies [Abstract]
Principles of Consolidation and Basis of Preparation	The consolidated financial statements include the accounts of Mattel, Inc. and its subsidiaries. All wholly and majority-owned subsidiaries are consolidated and included in Mattel’s consolidated financial statements. Mattel does not have any minority stock ownership interests in which it has a controlling financial interest that would require consolidation. All significant intercompany accounts and transactions have been eliminated upon consolidation. On January 1, 2018, Mattel adopted Accounting Standards Update ("ASU") 2017-07, Compensation - Retirement Benefits: Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. As a result, other selling and administrative expenses, operating income (loss), and other non-operating expense, net have been retrospectively restated. The impact to Mattel’s consolidated financial statements was not material. See further discussion in "Note 1 to the Consolidated Financial Statements—Summary of Significant Accounting Policies—New Accounting Pronouncements" and "Note 4 to the Consolidated Financial Statements—Employee Benefit Plans."
Use of Estimates	Preparation of the consolidated financial statements in conformity with accounting principles generally accepted in the United States of America ("U.S. GAAP") requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could ultimately differ from those estimates.
Cash and Equivalents	Cash and equivalents include short-term investments, which are highly liquid investments with maturities of three months or less when purchased. Such investments are stated at cost, which approximates market value.
Accounts Receivable and Allowance for Doubtful Accounts	Credit is granted to customers on an unsecured basis. Credit limits and payment terms are established based on extensive evaluations made on an ongoing basis throughout the fiscal year of the financial performance, cash generation, financing availability, and liquidity status of each customer. Customers are reviewed at least annually, with more frequent reviews performed as necessary, based on the customers’ financial condition and the level of credit being extended. For customers who are experiencing financial difficulties, management performs additional financial analyses before shipping to those customers on credit. Mattel uses a variety of financial arrangements to ensure collectibility of accounts receivable of customers deemed to be a credit risk, including requiring letters of credit, purchasing various forms of credit insurance with unrelated third parties, factoring, or requiring cash in advance of shipment. Mattel records an allowance for doubtful accounts based on management’s assessment of the business environment, customers’ financial condition, historical collection experience, accounts receivable aging, and customer disputes.
Inventories	Inventories, net of allowance for obsolescence, are stated at the lower of cost or net realizable value. Expense associated with the allowance for obsolescence is recognized in cost of sales and establishes a lower cost basis for the inventory. Cost is determined by the first-in, first-out method.
Property, Plant, and Equipment	Property, plant, and equipment are stated at cost less accumulated depreciation. Depreciation is computed using the straight-line method over estimated useful lives of 10 to 30 years for buildings, 3 to 15 years for machinery and equipment, 3 to 10 years for software, and 10 to 20 years, not to exceed the lease term, for leasehold improvements. Tools, dies, and molds are depreciated using the straight-line method over 3 years. Estimated useful lives are periodically reviewed and, where appropriate, changes are made prospectively. The carrying value of property, plant, and equipment is reviewed when events or changes in circumstances indicate that the carrying value of an asset may not be recoverable. Any potential impairment identified is initially assessed by evaluating the operating performance and future undiscounted cash flows of the underlying assets. When property is sold or retired, the cost of the property and the related accumulated depreciation are removed from the consolidated balance sheets, and any resulting gain or loss is included in the consolidated statements of operations.
Goodwill	Goodwill is allocated to various reporting units, which are at the operating segment level, for the purpose of evaluating whether goodwill is impaired. Mattel’s reporting units are: (i) North America, (ii) International, and (iii) American Girl. Components of the operating segments have been aggregated into a single reporting unit as the components have similar economic characteristics. The similar economic characteristics include the nature of the products, the nature of the production processes, the customers, and the manner in which the products are distributed. Mattel tests its goodwill for impairment annually in the third quarter and whenever events or changes in circumstances indicate that the carrying value of a reporting unit may exceed its fair value.
Nonamortizable Intangible Assets	Mattel had no indefinite-lived intangible assets as of and for the years ended December 31, 2019 and December 31, 2018. Prior to 2018, Mattel tested indefinite-lived intangible assets for impairment annually in the third quarter or whenever events or changes in circumstances indicated that the carrying value may have exceeded its fair value.
Amortizable Intangible Assets	Mattel also tests its amortizable intangible assets, which are primarily comprised of trademarks and trade names, for impairment whenever events or changes in circumstances indicate that the carrying value of the asset may not be recovered. Amortization is computed primarily using the straight-line method over the estimated useful lives of the amortizable intangible assets.
Foreign Currency Translation Exposure	Mattel’s reporting currency is the U.S. dollar. The translation of its net investments in subsidiaries with non-U.S. dollar functional currencies subjects Mattel to the impact of currency exchange rate fluctuations in its results of operations and financial position. Assets and liabilities of subsidiaries with non-U.S. dollar functional currencies are translated into U.S. dollars at year-end exchange rates. Net income (loss) and cash flow items are translated at weighted-average exchange rates prevailing during the year. The resulting currency translation adjustments are recorded as a component of accumulated other comprehensive loss within stockholders’ equity.
Foreign Currency Transaction Exposure	Currency exchange rate fluctuations may impact Mattel’s results of operations and cash flows. Mattel’s currency transaction exposures include gains and losses realized on unhedged inventory purchases and unhedged receivables and payables balances that are denominated in a currency other than the applicable functional currency. Gains and losses on unhedged inventory purchases and other transactions associated with operating activities are recorded in the components of operating income (loss) in the consolidated statements of operations. Gains and losses on unhedged intercompany loans and advances are recorded as a component of other non-operating expense, net in the consolidated statements of operations in the period in which the currency exchange rate changes.
Derivative Instruments	Mattel uses foreign currency forward exchange contracts as cash flow hedges primarily to hedge its purchases and sales of inventory denominated in foreign currencies. At the inception of the contracts, Mattel designates these derivatives as cash flow hedges and documents the relationship of the hedge to the underlying transaction. Hedge effectiveness is assessed at inception and throughout the life of the hedge to ensure the hedge qualifies for hedge accounting. Changes in fair value associated with hedge ineffectiveness, if any, are recorded in the consolidated statements of operations. Changes in fair value of cash flow hedge derivatives are deferred and recorded as part of accumulated other comprehensive loss in stockholders’ equity until the underlying transaction affects earnings. In the event that an anticipated transaction is no longer likely to occur, Mattel recognizes the change in fair value of the derivative in its consolidated statements of operations in the period the determination is made. Additionally, Mattel uses foreign currency forward exchange contracts to hedge intercompany loans and advances denominated in foreign currencies. Due to the short-term nature of the contracts involved, Mattel does not use hedge accounting for these contracts, and as such, changes in fair value are recorded in the period of change in the consolidated statements of operations.
Revenue Recognition and Sales Adjustments	Revenue is recognized when control of the goods is transferred to the customer, which is either upon shipment or upon receipt of finished goods by the customer, depending on the contract terms. Mattel routinely enters into arrangements with its customers to provide sales incentives, support customer promotions, and provide allowances for returns or defective merchandise. Such programs are based primarily on customer purchases, customer performance of specified promotional activities, and other specified factors such as sales to consumers. Accruals for these programs are recorded as sales adjustments that reduce gross sales in the period the related sale is recognized. The accrual for such programs, which can either be contractual or discretionary in nature, is based on an assessment of customer purchases, customer performance of specified promotional activities, and other specified factors such as customer sales volume. In making these estimates, management considers all available information, including the overall business environment, historical trends, and information from customers. Mattel also enters into symbolic and functional licensing arrangements, whereby the licensee pays Mattel royalties based on sales of licensed product, and in certain cases are subject to minimum guaranteed amounts. The timing of revenue recognition for certain of these licensing arrangements with minimum guarantees changed under the new revenue recognition standards, which under the new revenue recognition standards is based on the determination of whether the license of intellectual property ("IP") is symbolic, which includes the license of Mattel's brands, or functional, which includes the license of Mattel's completed television or streaming content. Revenues from symbolic licenses of IP are recognized based on actual sales when Mattel expects royalties to exceed the minimum guarantee. For symbolic licensing arrangements in which Mattel does not expect royalties to exceed the minimum guarantee, an estimate of the royalties expected to be recouped is recognized on a straight-line basis over the license term. Revenues from functional licenses of IP are recognized once the license period has commenced and the licensee has the ability to use the delivered content. Mattel applied the practical expedient prescribed in the new revenue recognition standards and did not evaluate contracts of one year or less for the existence of a significant financing component. Multi-year contracts were not material.
Advertising and Promotion Costs	Costs of media advertising, including direct-response advertising, are capitalized and expensed the first time the advertising takes place
Product Recalls and Withdrawals	Mattel establishes a reserve for product recalls and withdrawals on a product-specific basis when circumstances giving rise to the recall or withdrawal become known. Facts and circumstances related to the recall or withdrawal, including where the product affected by the recall or withdrawal is located (e.g., with consumers, in customers’ inventory, or in Mattel’s inventory), cost estimates for shipping and handling for returns, cost estimates for communicating the recall or withdrawal to consumers and customers, and cost estimates for parts and labor if the recalled or withdrawn product is deemed to be repairable, are considered when establishing a product recall or withdrawal reserve. These factors are updated and reevaluated each period, and the related reserves are adjusted when these factors indicate that the recall or withdrawal reserve is either not sufficient to cover or exceeds the estimated product recall or withdrawal expenses.
Design and Development Costs	Product design and development costs primarily include employee compensation and outside services and are charged to the results of operations as incurred.
Employee Benefit Plans	Mattel and certain of its subsidiaries have retirement and other postretirement benefit plans covering substantially all employees of these entities. Actuarial valuations are used in determining amounts recognized in the financial statements for certain retirement and other postretirement benefit plans (see "Note 4 to the Consolidated Financial Statements—Employee Benefit Plans").
Share-Based Payments	Mattel recognizes the cost of service-based employee share-based payment awards on a straight-line attribution basis over the requisite employee service period, net of estimated forfeitures. Determining the fair value of share-based awards at the measurement date requires judgment, including estimating the expected term that stock options will be outstanding prior to exercise, the associated volatility, and the expected dividends. With the exception of certain market-based options granted in 2018, which are valued using a Monte Carlo valuation methodology, Mattel estimates the fair value of options granted using the Black-Scholes valuation model. The expected life of the options used in this calculation is the period of time the options are expected to be outstanding and has been determined based on historical exercise experience. Expected stock price volatility is based on the historical volatility of Mattel’s stock for a period approximating the expected life, the expected dividend yield is based on Mattel’s most recent actual annual dividend payout, and the risk-free interest rate is based on the implied yield available on U.S. Treasury zero-coupon issues approximating the expected life. Judgment is also required in estimating the amount of share-based awards that will be forfeited prior to vesting. Mattel determines the fair value of RSUs, excluding performance RSUs, based on the closing market price of Mattel’s common stock on the date of grant, adjusted by the present value of the expected dividends for RSUs that are not entitled to a dividend during the vest period. Mattel determines the fair value of the performance-related components of its performance RSUs based on the closing market price of Mattel's common stock on the date of grant. It determines the fair value of the market-related components of its performance RSUs based on a Monte Carlo valuation methodology.
Income Taxes	Certain income and expense items are accounted for differently for financial reporting and income tax purposes. Deferred income tax assets and liabilities are determined based on the difference between the financial statement and tax bases of assets and liabilities, applying enacted statutory income tax rates in effect for the year in which the differences are expected to reverse. Mattel evaluates the realization of our deferred tax assets based on all available evidence and establishes a valuation allowance to reduce deferred tax assets when it is more likely than not that they will not be realized. Mattel recognizes the financial statement effects of a tax position when it is more likely than not that, based on technical merits, the position will be sustained upon examination. The tax benefits of the position recognized in the financial statements are then measured based on the largest amount of benefit that is greater than 50% likely to be realized upon settlement with a taxing authority. In addition, we recognize interest and penalties related to unrecognized tax benefits as a component of the income tax provision. In the normal course of business, Mattel is regularly audited by federal, state, local, and foreign tax authorities. The ultimate settlement of any particular issue with the applicable taxing authority could have a material impact on Mattel’s consolidated financial statements.
Venezuelan Operations and Argentina Operations	Since January 1, 2010, Mattel has accounted for Venezuela as a highly inflationary economy as the three-year cumulative inflation rate for Venezuela exceeded 100%. Accordingly, Mattel’s Venezuelan subsidiary used the U.S. dollar as its functional currency, and monetary assets and liabilities denominated in Venezuelan bolívar fuerte ("BsF") generated income or expense for changes in value associated with foreign currency exchange rate fluctuations against the U.S. dollar. Effective July 1, 2018, Mattel accounted for Argentina as a highly inflationary economy, as the projected three-year cumulative inflation rate exceeded 100%. As such, beginning July 1, 2018, Mattel's Argentina subsidiary has designated the U.S. dollar as its functional currency. Mattel’s Argentina subsidiary represented less than 1% of Mattel's consolidated net sales for the years ended December 31, 2019 and 2018.
New Accounting Pronouncements	Recently Adopted Accounting Pronouncements In February 2016, the Financial Accounting Board ("FASB") issued ASU 2016-02, Leases (Topic 842), as amended. Mattel adopted the new lease standard on January 1, 2019 using the modified retrospective transition method. Prior periods were not retrospectively adjusted and continue to be reported under the accounting standards in effect for those periods, as further discussed in "Note 7 to the Consolidated Financial Statements—Leases." In August 2017, the FASB issued ASU 2017-12, Derivatives and Hedging: Targeted Improvements to Accounting for Hedging Activities, which expands the hedging strategies eligible for hedge accounting and changes both how companies assess hedge effectiveness and presentation and disclosure requirements. Mattel adopted ASU 2017-12 on January 1, 2019 and the adoption did not have a material impact on its consolidated financial statements. In February 2018, the FASB issued ASU 2018-02, Income Statement - Reporting Comprehensive Income: Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income, which permits the reclassification of disproportionate tax effects in accumulated other comprehensive income (loss) caused by the U.S. Tax Act to retained earnings. Mattel adopted ASU 2018-02 on January 1, 2019 and the adoption did not have a material impact on its consolidated financial statements. For additional information, see "Note 15 to the Consolidated Financial Statements—Income Taxes." Accounting Pronouncements Not Yet Adopted In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326), which changes the methodology for measuring credit losses on financial instruments and the timing of when such losses are recorded. This update replaces the existing incurred loss impairment model with an expected loss model (referred to as the Current Expected Credit Loss model, or "CECL"). In November 2018, the FASB issued ASU 2018-19, Codifications Improvements to Topic 326, Financial Instruments-Credit Losses" which clarifies that receivables arising from operating leases are accounted for using lease guidance and not as financial instruments. ASU 2016-13 and its related amendments (ASU 2018-19, ASU 2019-04, ASU 2019-05, ASU 2019-10, and ASU 2019-11) will become effective for the fiscal year beginning on January 1, 2020. During the fourth quarter of 2019, Mattel substantially completed its assessment of the impact of ASU 2016-13 and its related amendments on its consolidated financial statements and does not believe it will have a material impact on its consolidated financial statements. In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement, which modifies the disclosure requirements on fair value measurements, including the consideration of costs and benefits. ASU 2018-13 will become effective for interim and annual reporting periods beginning on January 1, 2020. The amendments on changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements, and the narrative description of measurement uncertainty will be applied prospectively for only the most recent interim or annual period presented in the initial fiscal year of adoption. All other amendments will be applied retrospectively to all periods presented upon their effective date. Early adoption is permitted. In addition, early adoption of any removed or modified disclosures, but delayed adoption of any additional disclosures until their effective date, is permitted. Mattel will adopt ASU 2018-13 on January 1, 2020 and does not expect the adoption to have a material impact on its consolidated financial statements. In August 2018, the FASB issued ASU 2018-14, Compensation - Retirement Benefits - Defined Benefit Plans - General (Subtopic 715-20): Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans, which modifies the disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans. ASU 2018-14 will become effective for the fiscal year beginning on January 1, 2021. Early adoption is permitted and the amendments will be applied on a retrospective basis to all periods presented. Mattel is currently evaluating the impact of the adoption of ASU 2018-14 on its consolidated financial statements. In March 2019, the FASB issued ASU 2019-02, Entertainment - Films - Other Assets - Film Costs (Subtopic 926-20): Improvements to Accounting for Costs of Films and License Agreements for Program Materials, which aligns the accounting for production costs of episodic television series with the accounting of films by removing the content distinction for capitalization. ASU 2019-02 will become effective for the fiscal year beginning on January 1, 2020. Mattel will adopt ASU 2019-02 on January 1, 2020 and does not expect the adoption to have a material impact on its consolidated financial statements. In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes, which simplifies the accounting for incomes taxes by removing certain exceptions to the general principles in Topic 740. The amendments also improve consistent application of and simplify the accounting for other areas of Topic 740 by clarifying and amending existing guidance. ASU 2019-12 will become effective for the fiscal year beginning on January 1, 2021. Early adoption is permitted. The amendments related to changes in ownership of foreign equity method investments or foreign subsidiaries will be applied on a modified retrospective basis through a cumulative effect adjustment to retained earnings as of January 1, 2007. The amendments related to franchise taxes that are partially based on income will be applied on either a retrospective basis for all periods presented or a modified retrospective basis through a cumulative effect adjustment to retained earnings as of January 1, 2007. All other amendments will be applied on a prospective basis. Mattel is currently evaluating the impact of the adoption of ASU 2019-12 on its consolidated financial statements.
Debt	Seasonal Financing On December 20, 2017, Mattel entered into a syndicated facility agreement (the "Credit Agreement"), as a borrower thereunder (in such capacity, the "Borrower"), along with certain of Mattel’s domestic subsidiaries, as additional borrowers thereunder (together with the Borrower, the "U.S. Borrowers"), Mattel Canada Inc. as a borrower thereunder (the "Canadian Borrower"), certain additional domestic and foreign subsidiaries of Mattel, as guarantors thereunder, Bank of America, N.A., as global administrative agent, collateral agent, Australian security trustee, and lender, and the other lenders and financial institutions party thereto, providing for $1.60 billion in aggregate principal amount of senior secured revolving credit facilities (the "senior secured revolving credit facilities"). The senior secured revolving credit facilities consist of an asset based lending facility with aggregate commitments of $1.31 billion, subject to borrowing base capacity, and a revolving credit facility with $294.0 million in aggregate commitments secured by certain fixed assets and intellectual property of the U.S. Borrowers and certain equity interests in various subsidiaries of Mattel, subject to borrowing base capacity (the "Fixed Asset & IP Facility"). The senior secured revolving credit facilities will mature on November 18, 2022. On March 28, 2018 and March 29, 2018, Mattel, Inc. and certain of its subsidiaries entered into various foreign joinder agreements to the Credit Agreement. The foreign joinder agreements join the relevant foreign borrowers and foreign lenders to the Credit Agreement, as contemplated therein, making portions of the senior secured revolving credit facilities available to other subsidiaries of Mattel, Inc. such that, together with the initial entry into the Credit Agreement, the senior secured revolving credit facilities are available to certain subsidiaries of Mattel, Inc., in their capacity as borrowers, located in the following jurisdictions: (i) the United States (the "U.S. Borrowers"), (ii) Canada (the "Canadian Borrower"), (iii) Germany, the Netherlands and the United Kingdom (the "European (GNU) Borrowers"), (iv) Spain (the "Spanish Borrower"), (v) France (the "French Borrower"), and (vi) Australia (the "Australian Borrower"), in each case through subfacilities in each such jurisdiction (each, a "Subfacility"). Through the initial Credit Agreement and the foreign joinder agreements, certain additional domestic and foreign subsidiaries of Mattel Inc., are also parties to the Credit Agreement as guarantors of various obligations of the borrowers under the Credit Agreement as further described below. On December 14, 2018, Mattel, Inc. entered into an amendment to the Credit Agreement, which included the expansion of eligibility criteria for accounts receivable and inventory included in the borrowing base. In support of the foregoing, two additional Mattel subsidiaries, Mattel Import Services, LLC ("MISL") and Mattel Finco Europe B.V. ("Mattel Finco") were added as borrowers to the Credit Agreement. The Credit Agreement allows for certain inventory located in the Czech Republic and the Netherlands to be included in the borrowing base. Additionally, certain accounts receivable with account debtors located in Italy and Poland, as well as other countries agreed upon with the Administrative Agent, may be purchased by Mattel Finco and added to the borrowing base in the future. On November 20, 2019, Mattel, Inc. entered into an amendment to the Credit Agreement, which included, but not limited to, amendments to certain definitions related to the borrowing base, a reduction in certain interest rates thereunder and an extension of the maturity date thereof. Each of the facilities under the Credit Agreement will mature, and lending commitments thereunder will terminate, on November 18, 2022. Borrowings under the senior secured revolving credit facilities will (i) be limited by jurisdiction-specific borrowing base calculations based on the sum of specified percentages of eligible accounts receivable, eligible inventory and certain fixed assets and intellectual property, as applicable, minus the amount of any applicable reserves, and (ii) bear interest at a floating rate, which can be either, at the Borrower’s option, (a) an adjusted LIBOR rate plus an applicable margin ranging from 1.25% to 2.75% per annum or (b) an alternate base rate plus an applicable margin ranging from 0.25% to 1.75% per annum, in each case, such applicable margins to be determined based on the Borrower’s average borrowing availability remaining under the senior secured revolving credit facilities. In addition to paying interest on the outstanding principal under the senior secured revolving credit facilities, the Borrower will be required to pay (i) an unused line fee per annum of the average daily unused portion of the senior secured revolving credit facilities, (ii) a letter of credit fronting fee based on a percentage of the aggregate face amount of outstanding letters of credit, and (iii) certain other customary fees and expenses of the lenders and agents. Outstanding letters of credit under the senior secured revolving credit facilities totaled approximately $55 million as of December 31, 2019. The U.S. Borrowers, as well as certain U.S. subsidiaries of the Borrower (the "U.S. Guarantors"), are guaranteeing the obligations of all Borrowers under the senior secured revolving credit facilities. Additionally, the obligations of the Canadian Borrower, the French Borrower, the Spanish Borrower, the European (GNU) Borrowers and the Australian Borrower (collectively, the "Foreign Borrowers"), respectively guaranteed by the obligations of the other Foreign Borrowers, as well as certain additional foreign subsidiaries ("Foreign Guarantors"). The U.S. Subfacility is secured by liens on substantially all of the U.S. Borrowers’ and the U.S. Guarantors’ accounts receivable and inventory (the "U.S. Current Assets Collateral"). The Canadian Subfacility, the French Subfacility, the Spanish Subfacility, the European (GNU) Subfacility, and the Australian Subfacility are, each secured by a first priority lien on (i) the accounts receivable and inventory of the applicable Foreign Borrower(s) and Foreign Guarantors under such facility, and (ii) the U.S. Current Assets Collateral. The Fixed Asset & IP Facility is secured by a first priority lien on certain owned real property in the U.S., certain U.S. trademarks and patents, and 100% of the equity interests in the U.S. Borrowers (aside from Mattel) and U.S. Guarantors, as well as 65% of the voting equity interests and 100% of the non-voting equity interests in Mattel Holdings Limited. Upon the additional Foreign Borrowers and Foreign Guarantors joining the Credit Agreement, the Fixed Asset & IP Facility will also be secured by 65% of the voting equity interests of such additional Foreign Borrowers and Foreign Guarantors that are directly owned by a U.S. Borrower or U.S. Guarantor. The net book value of the accounts receivable, inventory, and certain owned real property in the U.S. currently pledged as collateral under the senior secured revolving credit facilities was approximately $800 million as of December 31, 2019. The Credit Agreement contains customary covenants, including, but not limited to, restrictions on the Borrower’s and its subsidiaries’ ability to merge and consolidate with other companies, incur indebtedness, grant liens or security interests on assets, make acquisitions, loans, advances, or investments, pay dividends, sell or otherwise transfer assets outside of the ordinary course, optionally prepay or modify terms of any junior indebtedness, enter into transactions with affiliates, or change their line of business. The Credit Agreement requires the maintenance of a fixed charge coverage ratio of 1.00 to 1.00 at the end of each fiscal quarter when excess availability under the senior secured revolving credit facilities is less than the greater of (x) $100 million and (y) 10% of the aggregate amount available thereunder (the "Availability Threshold") and on the last day of each subsequent fiscal quarter ending thereafter until no event of default exists and excess availability is greater than the Availability Threshold for at least 30 consecutive days. Mattel had no borrowings under the senior secured revolving credit facilities as of December 31, 2019 and 2018. Since the execution of the Credit Agreement, the fixed charge coverage ratio covenant has not been in effect as no event of default occurred and as Mattel's excess availability was greater than $100 million and the Availability Threshold. As of December 31, 2019 and 2018, Mattel was in compliance with all covenants contained in the Credit Agreement. The Credit Agreement is a material agreement, and failure to comply with the covenants may result in an event of default under the terms of the senior secured revolving credit facilities. If Mattel were to default under the terms of the senior secured revolving credit facilities, its ability to meet its seasonal financing requirements could be adversely affected. To finance seasonal working capital requirements of certain foreign subsidiaries, Mattel avails itself of individual short-term credit lines. As of December 31, 2019, foreign credit lines totaled approximately $13 million. Mattel expects to extend the majority of these credit lines throughout 2020. Mattel believes its cash on hand, amounts available under the senior secured revolving credit facilities, and its foreign credit lines will be adequate to meet its seasonal financing requirements in 2020. Additionally, sales of foreign receivables occur periodically to finance seasonal working capital requirements. As of December 31, 2019 and 2018, there were no outstanding amounts of accounts receivable that were sold under international factoring arrangements.
Earnings Per Share	Unvested share-based payment awards that contain nonforfeitable rights to dividends or dividend equivalents (whether paid or unpaid) are participating securities and are included in the computation of earnings per share pursuant to the two-class method. Prior to June 30, 2018, certain of Mattel’s RSUs were considered participating securities because they contained nonforfeitable rights to dividend equivalents. Under the two-class method, net income is reduced by the amount of dividends declared in the period for each class of common stock and participating securities. The remaining undistributed earnings are then allocated to common stock and participating securities as if all of the net income for the period had been distributed. Basic earnings per common share excludes dilution and is calculated by dividing net income allocable to common shares by the weighted average number of common shares outstanding for the period. Diluted earnings per common share is calculated by dividing net income allocable to common shares by the weighted average number of common shares for the period, as adjusted for the potential dilutive effect of non-participating share-based awards.
Segment Reporting	Mattel does not include sales adjustments such as trade discounts and other allowances in the calculation of segment revenues (referred to as "gross sales" and reconciled to net sales in the tables below). Mattel records these adjustments in its financial accounting systems at the time of sale to each customer, but the adjustments are not allocated to individual products. For this reason, Mattel's Chief Operating Decision Maker uses gross and net sales by segment as metrics to measure segment performance. Such sales adjustments are included in the determination of segment income (loss) from operations based on the adjustments recorded in the financial accounting systems. Segment income (loss) represents each segment's operating income (loss), while consolidated operating income (loss) represents income (loss) from operations before net interest, other non-operating expense, net, and income taxes as reported in the consolidated statements of operations. The corporate and other expense category includes costs not allocated to individual segments, including charges related to incentive compensation, certain severance and other restructuring costs, share-based compensation, corporate headquarters functions managed on a worldwide basis, and the impact of changes in foreign currency exchange rates on intercompany transactions.
Income Tax Uncertainties	In assessing whether uncertain tax positions should be recognized in its financial statements, Mattel first determines whether it is more-likely-than-not that a tax position will be sustained upon examination, including resolution of any related appeals or litigation processes, based on the technical merits of the position. In evaluating whether a tax position has met the more-likely-than-not recognition threshold, Mattel presumes that the position will be examined by the appropriate taxing authority that would have full knowledge of all relevant information. For tax positions that meet the more-likely-than-not recognition threshold, Mattel measures the amount of benefit recognized in the financial statements at the largest amount of benefit that is greater than 50 percent likely of being realized upon ultimate settlement. Mattel recognizes unrecognized tax benefits in the first financial reporting period in which information becomes available indicating that such benefits will more-likely-than-not be realized.

Summary of Significant Accounting Policies (Policies)

12 Months Ended

Dec. 31, 2019

Principles of Consolidation and Basis of Preparation

The consolidated financial statements include the accounts of Mattel, Inc. and its subsidiaries. All wholly and majority-owned subsidiaries are consolidated and included in Mattel’s consolidated financial statements. Mattel does not have any minority stock ownership interests in which it has a controlling financial interest that would require consolidation. All significant intercompany accounts and transactions have been eliminated upon consolidation.

On January 1, 2018, Mattel adopted Accounting Standards Update ("ASU") 2017-07, Compensation - Retirement Benefits: Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. As a result, other selling and administrative expenses, operating income (loss), and other non-operating expense, net have been retrospectively restated. The impact to Mattel’s consolidated financial statements was not material. See further discussion in "Note 1 to the Consolidated Financial Statements—Summary of Significant Accounting Policies—New Accounting Pronouncements" and "Note 4 to the Consolidated Financial Statements—Employee Benefit Plans."

Use of Estimates

Preparation of the consolidated financial statements in conformity with accounting principles generally accepted in the United States of America ("U.S. GAAP") requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could ultimately differ from those estimates.

Cash and Equivalents

Cash and equivalents include short-term investments, which are highly liquid investments with maturities of three months or less when purchased. Such investments are stated at cost, which approximates market value.

Accounts Receivable and Allowance for Doubtful Accounts

Credit is granted to customers on an unsecured basis. Credit limits and payment terms are established based on extensive evaluations made on an ongoing basis throughout the fiscal year of the financial performance, cash generation, financing availability, and liquidity status of each customer. Customers are reviewed at least annually, with more frequent reviews performed as necessary, based on the customers’ financial condition and the level of credit being extended. For customers who are experiencing financial difficulties, management performs additional financial analyses before shipping to those customers on credit. Mattel uses a variety of financial arrangements to ensure collectibility of accounts receivable of customers deemed to be a credit risk, including requiring letters of credit, purchasing various forms of credit insurance with unrelated third parties, factoring, or requiring cash in advance of shipment.

Mattel records an allowance for doubtful accounts based on management’s assessment of the business environment, customers’ financial condition, historical collection experience, accounts receivable aging, and customer disputes.

Inventories

Inventories, net of allowance for obsolescence, are stated at the lower of cost or net realizable value. Expense associated with the allowance for obsolescence is recognized in cost of sales and establishes a lower cost basis for the inventory. Cost is determined by the first-in, first-out method.

Property, Plant, and Equipment

Property, plant, and equipment are stated at cost less accumulated depreciation. Depreciation is computed using the straight-line method over estimated useful lives of 10 to 30 years for buildings, 3 to 15 years for machinery and equipment, 3 to 10 years for software, and 10 to 20 years, not to exceed the lease term, for leasehold improvements. Tools, dies, and molds are depreciated using the straight-line method over 3 years. Estimated useful lives are periodically reviewed and, where appropriate, changes are made prospectively. The carrying value of property, plant, and equipment is reviewed when events or changes in circumstances indicate that the carrying value of an asset may not be recoverable. Any potential impairment identified is initially assessed by evaluating the operating performance and future undiscounted cash flows of the underlying assets. When property is sold or retired, the cost of the property and the related accumulated depreciation are removed from the consolidated balance sheets, and any resulting gain or loss is included in the consolidated statements of operations.

Goodwill

Goodwill is allocated to various reporting units, which are at the operating segment level, for the purpose of evaluating whether goodwill is impaired. Mattel’s reporting units are: (i) North America, (ii) International, and (iii) American Girl. Components of the operating segments have been aggregated into a single reporting unit as the components have similar economic characteristics. The similar economic characteristics include the nature of the products, the nature of the production processes, the customers, and the manner in which the products are distributed. Mattel tests its goodwill for impairment annually in the third quarter and whenever events or changes in circumstances indicate that the carrying value of a reporting unit may exceed its fair value.

Nonamortizable Intangible Assets

Mattel had no indefinite-lived intangible assets as of and for the years ended December 31, 2019 and December 31, 2018. Prior to 2018, Mattel tested indefinite-lived intangible assets for impairment annually in the third quarter or whenever events or changes in circumstances indicated that the carrying value may have exceeded its fair value.

Amortizable Intangible Assets

Mattel also tests its amortizable intangible assets, which are primarily comprised of trademarks and trade names, for impairment whenever events or changes in circumstances indicate that the carrying value of the asset may not be recovered. Amortization is computed primarily using the straight-line method over the estimated useful lives of the amortizable intangible assets.

Foreign Currency Translation Exposure

Mattel’s reporting currency is the U.S. dollar. The translation of its net investments in subsidiaries with non-U.S. dollar functional currencies subjects Mattel to the impact of currency exchange rate fluctuations in its results of operations and financial position. Assets and liabilities of subsidiaries with non-U.S. dollar functional currencies are translated into U.S. dollars at year-end exchange rates. Net income (loss) and cash flow items are translated at weighted-average exchange rates prevailing during the year. The resulting currency translation adjustments are recorded as a component of accumulated other comprehensive loss within stockholders’ equity.

Foreign Currency Transaction Exposure

Currency exchange rate fluctuations may impact Mattel’s results of operations and cash flows. Mattel’s currency transaction exposures include gains and losses realized on unhedged inventory purchases and unhedged receivables and payables balances that are denominated in a currency other than the applicable functional currency. Gains and losses on unhedged inventory purchases and other transactions associated with operating activities are recorded in the components of operating income (loss) in the consolidated statements of operations. Gains and losses on unhedged intercompany loans and advances are recorded as a component of other non-operating expense, net in the consolidated statements of operations in the period in which the currency exchange rate changes.

Derivative Instruments

Mattel uses foreign currency forward exchange contracts as cash flow hedges primarily to hedge its purchases and sales of inventory denominated in foreign currencies. At the inception of the contracts, Mattel designates these derivatives as cash flow hedges and documents the relationship of the hedge to the underlying transaction. Hedge effectiveness is assessed at inception and throughout the life of the hedge to ensure the hedge qualifies for hedge accounting. Changes in fair value associated with hedge ineffectiveness, if any, are recorded in the consolidated statements of operations. Changes in fair value of cash flow hedge derivatives are deferred and recorded as part of accumulated other comprehensive loss in stockholders’ equity until the underlying transaction affects earnings. In the event that an anticipated transaction is no longer likely to occur, Mattel recognizes the change in fair value of the derivative in its consolidated statements of operations in the period the determination is made.

Additionally, Mattel uses foreign currency forward exchange contracts to hedge intercompany loans and advances denominated in foreign currencies. Due to the short-term nature of the contracts involved, Mattel does not use hedge accounting for these contracts, and as such, changes in fair value are recorded in the period of change in the consolidated statements of operations.

Revenue Recognition and Sales Adjustments

Revenue is recognized when control of the goods is transferred to the customer, which is either upon shipment or upon receipt of finished goods by the customer, depending on the contract terms. Mattel routinely enters into arrangements with its customers to provide sales incentives, support customer promotions, and provide allowances for returns or defective merchandise. Such programs are based primarily on customer purchases, customer performance of specified promotional activities, and other specified factors such as sales to consumers. Accruals for these programs are recorded as sales adjustments that reduce gross sales in the period the related sale is recognized.

The accrual for such programs, which can either be contractual or discretionary in nature, is based on an assessment of customer purchases, customer performance of specified promotional activities, and other specified factors such as customer sales volume. In making these estimates, management considers all available information, including the overall business environment, historical trends, and information from customers.

Mattel also enters into symbolic and functional licensing arrangements, whereby the licensee pays Mattel royalties based on sales of licensed product, and in certain cases are subject to minimum guaranteed amounts. The timing of revenue recognition for certain of these licensing arrangements with minimum guarantees changed under the new revenue recognition standards, which under the new revenue recognition standards is based on the determination of whether the license of intellectual property ("IP") is symbolic, which includes the license of Mattel's brands, or functional, which includes the license of Mattel's completed television or streaming content.

Revenues from symbolic licenses of IP are recognized based on actual sales when Mattel expects royalties to exceed the minimum guarantee. For symbolic licensing arrangements in which Mattel does not expect royalties to exceed the minimum guarantee, an estimate of the royalties expected to be recouped is recognized on a straight-line basis over the license term.

Revenues from functional licenses of IP are recognized once the license period has commenced and the licensee has the ability to use the delivered content.

Mattel applied the practical expedient prescribed in the new revenue recognition standards and did not evaluate contracts of one year or less for the existence of a significant financing component. Multi-year contracts were not material.

Advertising and Promotion Costs

Costs of media advertising, including direct-response advertising, are capitalized and expensed the first time the advertising takes place

Product Recalls and Withdrawals

Mattel establishes a reserve for product recalls and withdrawals on a product-specific basis when circumstances giving rise to the recall or withdrawal become known. Facts and circumstances related to the recall or withdrawal, including where the product affected by the recall or withdrawal is located (e.g., with consumers, in customers’ inventory, or in Mattel’s inventory), cost estimates for shipping and handling for returns, cost estimates for communicating the recall or withdrawal to consumers and customers, and cost estimates for parts and labor if the recalled or withdrawn product is deemed to be repairable, are considered when establishing a product recall or withdrawal reserve. These factors are updated and reevaluated each period, and the related reserves are adjusted when these factors indicate that the recall or withdrawal reserve is either not sufficient to cover or exceeds the estimated product recall or withdrawal expenses.

Design and Development Costs

Product design and development costs primarily include employee compensation and outside services and are charged to the results of operations as incurred.

Employee Benefit Plans

Mattel and certain of its subsidiaries have retirement and other postretirement benefit plans covering substantially all employees of these entities. Actuarial valuations are used in determining amounts recognized in the financial statements for certain retirement and other postretirement benefit plans (see "Note 4 to the Consolidated Financial Statements—Employee Benefit Plans").

Share-Based Payments

Mattel recognizes the cost of service-based employee share-based payment awards on a straight-line attribution basis over the requisite employee service period, net of estimated forfeitures.

Determining the fair value of share-based awards at the measurement date requires judgment, including estimating the expected term that stock options will be outstanding prior to exercise, the associated volatility, and the expected dividends. With the exception of certain market-based options granted in 2018, which are valued using a Monte Carlo valuation methodology, Mattel estimates the fair value of options granted using the Black-Scholes valuation model. The expected life of the options used in this calculation is the period of time the options are expected to be outstanding and has been determined based on historical exercise experience. Expected stock price volatility is based on the historical volatility of Mattel’s stock for a period approximating the expected life, the expected dividend yield is based on Mattel’s most recent actual annual dividend payout, and the risk-free interest rate is based on the implied yield available on U.S. Treasury zero-coupon issues approximating the expected life. Judgment is also required in estimating the amount of share-based awards that will be forfeited prior to vesting.

Mattel determines the fair value of RSUs, excluding performance RSUs, based on the closing market price of Mattel’s common stock on the date of grant, adjusted by the present value of the expected dividends for RSUs that are not entitled to a dividend during the vest period.

Mattel determines the fair value of the performance-related components of its performance RSUs based on the closing market price of Mattel's common stock on the date of grant. It determines the fair value of the market-related components of its performance RSUs based on a Monte Carlo valuation methodology.

Income Taxes

Certain income and expense items are accounted for differently for financial reporting and income tax purposes. Deferred income tax assets and liabilities are determined based on the difference between the financial statement and tax bases of assets and liabilities, applying enacted statutory income tax rates in effect for the year in which the differences are expected to reverse. Mattel evaluates the realization of our deferred tax assets based on all available evidence and establishes a valuation allowance to reduce deferred tax assets when it is more likely than not that they will not be realized.

Mattel recognizes the financial statement effects of a tax position when it is more likely than not that, based on technical merits, the position will be sustained upon examination. The tax benefits of the position recognized in the financial statements are then measured based on the largest amount of benefit that is greater than 50% likely to be realized upon settlement with a taxing authority. In addition, we recognize interest and penalties related to unrecognized tax benefits as a component of the income tax provision.

In the normal course of business, Mattel is regularly audited by federal, state, local, and foreign tax authorities. The ultimate settlement of any particular issue with the applicable taxing authority could have a material impact on Mattel’s consolidated financial statements.

Venezuelan Operations and Argentina Operations

Since January 1, 2010, Mattel has accounted for Venezuela as a highly inflationary economy as the three-year cumulative inflation rate for Venezuela exceeded 100%. Accordingly, Mattel’s Venezuelan subsidiary used the U.S. dollar as its functional currency, and monetary assets and liabilities denominated in Venezuelan bolívar fuerte ("BsF") generated income or expense for changes in value associated with foreign currency exchange rate fluctuations against the U.S. dollar.

Effective July 1, 2018, Mattel accounted for Argentina as a highly inflationary economy, as the projected three-year cumulative inflation rate exceeded 100%. As such, beginning July 1, 2018, Mattel's Argentina subsidiary has designated the U.S. dollar as its functional currency. Mattel’s Argentina subsidiary represented less than 1% of Mattel's consolidated net sales for the years ended December 31, 2019 and 2018.

New Accounting Pronouncements

Recently Adopted Accounting Pronouncements

In February 2016, the Financial Accounting Board ("FASB") issued ASU 2016-02, Leases (Topic 842), as amended. Mattel adopted the new lease standard on January 1, 2019 using the modified retrospective transition method. Prior periods were not retrospectively adjusted and continue to be reported under the accounting standards in effect for those periods, as further discussed in "Note 7 to the Consolidated Financial Statements—Leases."

In August 2017, the FASB issued ASU 2017-12, Derivatives and Hedging: Targeted Improvements to Accounting for Hedging Activities, which expands the hedging strategies eligible for hedge accounting and changes both how companies assess hedge effectiveness and presentation and disclosure requirements. Mattel adopted ASU 2017-12 on January 1, 2019 and the adoption did not have a material impact on its consolidated financial statements.

In February 2018, the FASB issued ASU 2018-02, Income Statement - Reporting Comprehensive Income: Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income, which permits the reclassification of disproportionate tax effects in accumulated other comprehensive income (loss) caused by the U.S. Tax Act to retained earnings. Mattel adopted ASU 2018-02 on January 1, 2019 and the adoption did not have a material impact on its consolidated financial statements. For additional information, see "Note 15 to the Consolidated Financial Statements—Income Taxes."

Accounting Pronouncements Not Yet Adopted

In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses (Topic 326), which changes the methodology for measuring credit losses on financial instruments and the timing of when such losses are recorded. This update replaces the existing incurred loss impairment model with an expected loss model (referred to as the Current Expected Credit Loss model, or "CECL"). In November 2018, the FASB issued ASU 2018-19, Codifications Improvements to Topic 326, Financial Instruments-Credit Losses" which clarifies that receivables arising from operating leases are accounted for using lease guidance and not as financial instruments. ASU 2016-13 and its related amendments (ASU 2018-19, ASU 2019-04, ASU 2019-05, ASU 2019-10, and ASU 2019-11) will become effective for the fiscal year beginning on January 1, 2020. During the fourth quarter of 2019, Mattel substantially completed its assessment of the impact of ASU 2016-13 and its related amendments on its consolidated financial statements and does not believe it will have a material impact on its consolidated financial statements.

In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework - Changes to the Disclosure Requirements for Fair Value Measurement, which modifies the disclosure requirements on fair value measurements, including the consideration of costs and benefits. ASU 2018-13 will become effective for interim and annual reporting periods beginning on January 1, 2020. The amendments on changes in unrealized gains and losses, the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements, and the narrative description of measurement uncertainty will be applied prospectively for only the most recent interim or annual period presented in the initial fiscal year of adoption. All other amendments will be applied retrospectively to all periods presented upon their effective date. Early adoption is permitted. In addition, early adoption of any removed or modified disclosures, but delayed adoption of any additional disclosures until their effective date, is permitted. Mattel will adopt ASU 2018-13 on January 1, 2020 and does not expect the adoption to have a material impact on its consolidated financial statements.

In August 2018, the FASB issued ASU 2018-14, Compensation - Retirement Benefits - Defined Benefit Plans - General (Subtopic 715-20): Disclosure Framework - Changes to the Disclosure Requirements for Defined Benefit Plans, which modifies the disclosure requirements for employers that sponsor defined benefit pension or other postretirement plans. ASU 2018-14 will become effective for the fiscal year beginning on January 1, 2021. Early adoption is permitted and the amendments will be applied on a retrospective basis to all periods presented. Mattel is currently evaluating the impact of the adoption of ASU 2018-14 on its consolidated financial statements.

In March 2019, the FASB issued ASU 2019-02, Entertainment - Films - Other Assets - Film Costs (Subtopic 926-20): Improvements to Accounting for Costs of Films and License Agreements for Program Materials, which aligns the accounting for production costs of episodic television series with the accounting of films by removing the content distinction for capitalization. ASU 2019-02 will become effective for the fiscal year beginning on January 1, 2020. Mattel will adopt ASU 2019-02 on January 1, 2020 and does not expect the adoption to have a material impact on its consolidated financial statements.

In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes, which simplifies the accounting for incomes taxes by removing certain exceptions to the general principles in Topic 740. The amendments also improve consistent application of and simplify the accounting for other areas of Topic 740 by clarifying and amending existing guidance. ASU 2019-12 will become effective for the fiscal year beginning on January 1, 2021. Early adoption is permitted. The amendments related to changes in ownership of foreign equity method investments or foreign subsidiaries will be applied on a modified retrospective basis through a cumulative effect adjustment to retained earnings as of January 1, 2007. The amendments related to franchise taxes that are partially based on income will be applied on either a retrospective basis for all periods presented or a modified retrospective basis through a cumulative effect adjustment to retained earnings as of January 1, 2007. All other amendments will be applied on a prospective basis. Mattel is currently evaluating the impact of the adoption of ASU 2019-12 on its consolidated financial statements.

Debt

Seasonal Financing

On December 20, 2017, Mattel entered into a syndicated facility agreement (the "Credit Agreement"), as a borrower thereunder (in such capacity, the "Borrower"), along with certain of Mattel’s domestic subsidiaries, as additional borrowers thereunder (together with the Borrower, the "U.S. Borrowers"), Mattel Canada Inc. as a borrower thereunder (the "Canadian Borrower"), certain additional domestic and foreign subsidiaries of Mattel, as guarantors thereunder, Bank of America, N.A., as global administrative agent, collateral agent, Australian security trustee, and lender, and the other lenders and financial institutions party thereto, providing for $1.60 billion in aggregate principal amount of senior secured revolving credit facilities (the "senior secured revolving credit facilities"). The senior secured revolving credit facilities consist of an asset based lending facility with aggregate commitments of $1.31 billion, subject to borrowing base capacity, and a revolving credit facility with $294.0 million in aggregate commitments secured by certain fixed assets and intellectual property of the U.S. Borrowers and certain equity interests in various subsidiaries of Mattel, subject to borrowing base capacity (the "Fixed Asset & IP Facility"). The senior secured revolving credit facilities will mature on November 18, 2022.

On March 28, 2018 and March 29, 2018, Mattel, Inc. and certain of its subsidiaries entered into various foreign joinder agreements to the Credit Agreement. The foreign joinder agreements join the relevant foreign borrowers and foreign lenders to the Credit Agreement, as contemplated therein, making portions of the senior secured revolving credit facilities available to other subsidiaries of Mattel, Inc. such that, together with the initial entry into the Credit Agreement, the senior secured revolving credit facilities are available to certain subsidiaries of Mattel, Inc., in their capacity as borrowers, located in the following jurisdictions: (i) the United States (the "U.S. Borrowers"), (ii) Canada (the "Canadian Borrower"), (iii) Germany, the Netherlands and the United Kingdom (the "European (GNU) Borrowers"), (iv) Spain (the "Spanish Borrower"), (v) France (the "French Borrower"), and (vi) Australia (the "Australian Borrower"), in each case through subfacilities in each such jurisdiction (each, a "Subfacility"). Through the initial Credit Agreement and the foreign joinder agreements, certain additional domestic and foreign subsidiaries of Mattel Inc., are also parties to the Credit Agreement as guarantors of various obligations of the borrowers under the Credit Agreement as further described below.

On December 14, 2018, Mattel, Inc. entered into an amendment to the Credit Agreement, which included the expansion of eligibility criteria for accounts receivable and inventory included in the borrowing base. In support of the foregoing, two additional Mattel subsidiaries, Mattel Import Services, LLC ("MISL") and Mattel Finco Europe B.V. ("Mattel Finco") were added as borrowers to the Credit Agreement. The Credit Agreement allows for certain inventory located in the Czech Republic and the Netherlands to be included in the borrowing base. Additionally, certain accounts receivable with account debtors located in Italy and Poland, as well as other countries agreed upon with the Administrative Agent, may be purchased by Mattel Finco and added to the borrowing base in the future.

On November 20, 2019, Mattel, Inc. entered into an amendment to the Credit Agreement, which included, but not limited to, amendments to certain definitions related to the borrowing base, a reduction in certain interest rates thereunder and an extension of the maturity date thereof. Each of the facilities under the Credit Agreement will mature, and lending commitments thereunder will terminate, on November 18, 2022.

Borrowings under the senior secured revolving credit facilities will (i) be limited by jurisdiction-specific borrowing base calculations based on the sum of specified percentages of eligible accounts receivable, eligible inventory and certain fixed assets and intellectual property, as applicable, minus the amount of any applicable reserves, and (ii) bear interest at a floating rate, which can be either, at the Borrower’s option, (a) an adjusted LIBOR rate plus an applicable margin ranging from 1.25% to 2.75% per annum or (b) an alternate base rate plus an applicable margin ranging from 0.25% to 1.75% per annum, in each case, such applicable margins to be determined based on the Borrower’s average borrowing availability remaining under the senior secured revolving credit facilities.

In addition to paying interest on the outstanding principal under the senior secured revolving credit facilities, the Borrower will be required to pay (i) an unused line fee per annum of the average daily unused portion of the senior secured revolving credit facilities, (ii) a letter of credit fronting fee based on a percentage of the aggregate face amount of outstanding letters of credit, and (iii) certain other customary fees and expenses of the lenders and agents. Outstanding letters of credit under the senior secured revolving credit facilities totaled approximately $55 million as of December 31, 2019.

The U.S. Borrowers, as well as certain U.S. subsidiaries of the Borrower (the "U.S. Guarantors"), are guaranteeing the obligations of all Borrowers under the senior secured revolving credit facilities. Additionally, the obligations of the Canadian Borrower, the French Borrower, the Spanish Borrower, the European (GNU) Borrowers and the Australian Borrower (collectively, the "Foreign Borrowers"), respectively guaranteed by the obligations of the other Foreign Borrowers, as well as certain additional foreign subsidiaries ("Foreign Guarantors").

The U.S. Subfacility is secured by liens on substantially all of the U.S. Borrowers’ and the U.S. Guarantors’ accounts receivable and inventory (the "U.S. Current Assets Collateral"). The Canadian Subfacility, the French Subfacility, the Spanish Subfacility, the European (GNU) Subfacility, and the Australian Subfacility are, each secured by a first priority lien on (i) the accounts receivable and inventory of the applicable Foreign Borrower(s) and Foreign Guarantors under such facility, and (ii) the U.S. Current Assets Collateral. The Fixed Asset & IP Facility is secured by a first priority lien on certain owned real property in the U.S., certain U.S. trademarks and patents, and 100% of the equity interests in the U.S. Borrowers (aside from Mattel) and U.S. Guarantors, as well as 65% of the voting equity interests and 100% of the non-voting equity interests in Mattel Holdings Limited. Upon the additional Foreign Borrowers and Foreign Guarantors joining the Credit Agreement, the Fixed Asset & IP Facility will also be secured by 65% of the voting equity interests of such additional Foreign Borrowers and Foreign Guarantors that are directly owned by a U.S. Borrower or U.S. Guarantor. The net book value of the accounts receivable, inventory, and certain owned real property in the U.S. currently pledged as collateral under the senior secured revolving credit facilities was approximately $800 million as of December 31, 2019.

The Credit Agreement contains customary covenants, including, but not limited to, restrictions on the Borrower’s and its subsidiaries’ ability to merge and consolidate with other companies, incur indebtedness, grant liens or security interests on assets, make acquisitions, loans, advances, or investments, pay dividends, sell or otherwise transfer assets outside of the ordinary course, optionally prepay or modify terms of any junior indebtedness, enter into transactions with affiliates, or change their line of business.

The Credit Agreement requires the maintenance of a fixed charge coverage ratio of 1.00 to 1.00 at the end of each fiscal quarter when excess availability under the senior secured revolving credit facilities is less than the greater of (x) $100 million and (y) 10% of the aggregate amount available thereunder (the "Availability Threshold") and on the last day of each subsequent fiscal quarter ending thereafter until no event of default exists and excess availability is greater than the Availability Threshold for at least 30 consecutive days.

Mattel had no borrowings under the senior secured revolving credit facilities as of December 31, 2019 and 2018. Since the execution of the Credit Agreement, the fixed charge coverage ratio covenant has not been in effect as no event of default occurred and as Mattel's excess availability was greater than $100 million and the Availability Threshold. As of December 31, 2019 and 2018, Mattel was in compliance with all covenants contained in the Credit Agreement. The Credit Agreement is a material agreement, and failure to comply with the covenants may result in an event of default under the terms of the senior secured revolving credit facilities. If Mattel were to default under the terms of the senior secured revolving credit facilities, its ability to meet its seasonal financing requirements could be adversely affected.

To finance seasonal working capital requirements of certain foreign subsidiaries, Mattel avails itself of individual short-term credit lines. As of December 31, 2019, foreign credit lines totaled approximately $13 million. Mattel expects to extend the majority of these credit lines throughout 2020.

Mattel believes its cash on hand, amounts available under the senior secured revolving credit facilities, and its foreign credit lines will be adequate to meet its seasonal financing requirements in 2020.

Additionally, sales of foreign receivables occur periodically to finance seasonal working capital requirements. As of December 31, 2019 and 2018, there were no outstanding amounts of accounts receivable that were sold under international factoring arrangements.

Earnings Per Share

Unvested share-based payment awards that contain nonforfeitable rights to dividends or dividend equivalents (whether paid or unpaid) are participating securities and are included in the computation of earnings per share pursuant to the two-class method. Prior to June 30, 2018, certain of Mattel’s RSUs were considered participating securities because they contained nonforfeitable rights to dividend equivalents.

Under the two-class method, net income is reduced by the amount of dividends declared in the period for each class of common stock and participating securities. The remaining undistributed earnings are then allocated to common stock and participating securities as if all of the net income for the period had been distributed. Basic earnings per common share excludes dilution and is calculated by dividing net income allocable to common shares by the weighted average number of common shares outstanding for the period. Diluted earnings per common share is calculated by dividing net income allocable to common shares by the weighted average number of common shares for the period, as adjusted for the potential dilutive effect of non-participating share-based awards.

Segment Reporting

Mattel does not include sales adjustments such as trade discounts and other allowances in the calculation of segment revenues (referred to as "gross sales" and reconciled to net sales in the tables below). Mattel records these adjustments in its financial accounting systems at the time of sale to each customer, but the adjustments are not allocated to individual products. For this reason, Mattel's Chief Operating Decision Maker uses gross and net sales by segment as metrics to measure segment performance. Such sales adjustments are included in the determination of segment income (loss) from operations based on the adjustments recorded in the financial accounting systems. Segment income (loss) represents each segment's operating income (loss), while consolidated operating income (loss) represents income (loss) from operations before net interest, other non-operating expense, net, and income taxes as reported in the consolidated statements of operations. The corporate and other expense category includes costs not allocated to individual segments, including charges related to incentive compensation, certain severance and other restructuring costs, share-based compensation, corporate headquarters functions managed on a worldwide basis, and the impact of changes in foreign currency exchange rates on intercompany transactions.

Income Tax Uncertainties

In assessing whether uncertain tax positions should be recognized in its financial statements, Mattel first determines whether it is more-likely-than-not that a tax position will be sustained upon examination, including resolution of any related appeals or litigation processes, based on the technical merits of the position. In evaluating whether a tax position has met the more-likely-than-not recognition threshold, Mattel presumes that the position will be examined by the appropriate taxing authority that would have full knowledge of all relevant information. For tax positions that meet the more-likely-than-not recognition threshold, Mattel measures the amount of benefit recognized in the financial statements at the largest amount of benefit that is greater than 50 percent likely of being realized upon ultimate settlement. Mattel recognizes unrecognized tax benefits in the first financial reporting period in which information becomes available indicating that such benefits will more-likely-than-not be realized.
