(Cautionary Statement Under the Private Securities Litigation Reform Act of 1995)
Mattel is including this Cautionary Statement to caution investors and qualify for the safe harbor provisions of the Private Securities Litigation Reform Act of 1995 (the "Act") for forward-looking statements. This Quarterly Report on Form 10-Q includes forward-looking statements within the meaning of the Act. Forward-looking statements can be identified by the fact that they do not relate strictly to historical or current facts. The use of words such as "anticipates," "expects," "intends," "plans," "confident that," and "believes," among others, generally identify forward-looking statements. These forward-looking statements are based on currently available operating, financial, economic, and other information and assumptions, and are subject to a number of significant risks and uncertainties. A variety of factors, many of which are beyond our control, could cause actual future results to differ materially from those projected in the forward-looking statements, and are currently, and in the future may be, amplified by the COVID-19 pandemic. Specific factors that might cause such a difference include, but are not limited to: (i) potential impacts of and uncertainty regarding the COVID-19 pandemic (and actions taken in response to it by governments, businesses, and individuals) on our business operations, financial results and financial position and on the global economy, including its impact on our sales; (ii) Mattel’s ability to design, develop, produce, manufacture, source, ship, and distribute products on a timely and cost-effective basis; (iii) sufficient interest in and demand for the products and entertainment we offer by retail customers and consumers to profitably recover Mattel’s costs; (iv) downturns in economic conditions affecting Mattel’s markets which can negatively impact retail customers and consumers, and which can result in lower employment levels and lower consumer disposable income and spending, including lower spending on purchases of Mattel’s products; (v) other factors which can lower discretionary consumer spending, such as higher costs for fuel and food, drops in the value of homes or other consumer assets, and high levels of consumer debt; (vi) potential difficulties or delays Mattel may experience in implementing cost savings and efficiency enhancing initiatives; (vii) other economic and public health conditions or regulatory changes in the markets in which Mattel and its customers and suppliers operate, which could create delays or increase Mattel’s costs, such as higher commodity prices, labor costs or transportation costs, or outbreaks of disease; (viii) currency fluctuations, including movements in foreign exchange rates, which can lower Mattel’s net revenues and earnings, and significantly impact Mattel’s costs; (ix) the concentration of Mattel’s customers, potentially increasing the negative impact to Mattel of difficulties experienced by any of Mattel’s customers, such as bankruptcies or liquidations or a general lack of success, or changes in their purchasing or selling patterns; (x) the inventory policies of Mattel’s retail customers, as well as the concentration of Mattel’s revenues in the second half of the year, which coupled with reliance by retailers on quick response inventory management techniques increases the risk of underproduction, overproduction, and shipping delays; (xi) legal, reputational, and financial risks related to security breaches or cyberattacks; (xii) work disruptions, which may impact Mattel’s ability to manufacture or deliver product in a timely and cost-effective manner; (xiii) the impact of competition on revenues, margins, and other aspects of Mattel’s business, including the ability to offer products which consumers choose to buy instead of competitive products, the ability to secure, maintain, and renew popular licenses from licensors of entertainment properties, and the ability to attract and retain talented employees; (xiv) the risk of product recalls or product liability suits and costs associated with product safety regulations; (xv) changes in laws or regulations in the United States and/or in other major markets, such as China, in which Mattel operates, including, without limitation, with respect to taxes, tariffs, trade policies, or product safety, which may increase Mattel’s product costs and other costs of doing business, and reduce Mattel’s earnings; (xvi) failure to realize the planned benefits from any investments or acquisitions made by Mattel; (xvii) the impact of other market conditions or third party actions or approvals, including that result in any significant failure, inadequacy, or interruption from vendors or outsourcers, which could reduce demand for Mattel’s products, delay or increase the cost of implementation of Mattel’s programs, or alter Mattel’s actions and reduce actual results; (xviii) changes in financing markets or the inability of Mattel to obtain financing on attractive terms; (xix) the impact of litigation, arbitration, or regulatory decisions or settlement actions; (xx) uncertainty from the expected discontinuance of LIBOR and transition to any other interest rate benchmark; and (xxi) other risks and uncertainties detailed in Part I, Item 1A "Risk Factors" in Mattel's 2020 Annual Report on Form 10-K (the "2020 Annual Report on Form 10-K"). Mattel does not update forward-looking statements and expressly disclaims any obligation to do so, except as required by law.

1. Basis of Presentation
The accompanying unaudited consolidated financial statements and related disclosures have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") applicable to interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X.

The December 31, 2020 balance sheet data was derived from audited financial statements; however, the accompanying interim notes to the consolidated financial statements do not include all of the annual disclosures required by GAAP.

The financial information included herein should be read in conjunction with Mattel's consolidated financial statements and related notes in the 2020 Annual Report on Form 10-K.
Certain prior period amounts have been reclassified to conform to the current period presentation.
2. Accounts Receivable

During the three months ended March 31, 2021, Mattel completed the sale of a manufacturing plant based in Mexico, which included land and buildings, resulting in a pre-tax gain o f $15.8 million. The assets sold were previously designated as held for sale, and included within property, plant, and equipment, net in the consolidated balance sheets as of December 31, 2020 and March 31, 2020.
5. 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.
The change in the carrying amount of goodwill by operating segment for the three months ended March 31, 2021 is shown below. Brand-specific goodwill held by foreign subsidiaries is allocated to the North America segment, thereby causing a foreign currency translation impact. During the three months ended March 31, 2021, Mattel sold its arts, crafts, and stationery business resulting in a reduction of goodwill of approximately $2 million.

8. Seasonal Financing
On December 20, 2017, Mattel entered into a syndicated facility agreement, which was subsequently amended in 2018, 2019, and 2021 (as amended, the "Credit Agreement"), as a borrower (in such capacity, the "Borrower") and guarantor thereunder, along with certain of the Borrower's domestic and foreign subsidiaries as additional borrowers and/or guarantors thereunder.
On March 19, 2021, Mattel entered into the fourth amendment to the Credit Agreement, which amended certain terms, including, but not limited to, certain components of the borrowing base, a reduction of the aggregate principal commitments of the senior secured revolving credit facilities (the "senior secured revolving credit facilities") from $1.60 billion to $1.40 billion, and an extension of the maturity date from November 18, 2022 to March 19, 2024.
The senior secured revolving credit facilities consist of (i) an asset based lending facility with aggregate commitments up to $1.11 billion, subject to borrowing base capacity, secured by substantially all of the accounts receivable and inventory of the Borrower and certain of its subsidiaries who are borrowers and/or guarantors under the Credit Agreement, as well as (ii) a revolving credit facility with $294.0 million in aggregate commitments secured by certain fixed assets and intellectual property of the U.S. borrowers under the Credit Agreement, and certain equity interests in the borrower and guarantor subsidiaries under the Credit Agreement.
Borrowings under the senior secured revolving credit facilities (i) are 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 1.75% per annum or (b) an alternate base rate plus an applicable margin ranging from 0.25% to 0.75% 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 is 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.
Mattel had no borrowings under the senior secured revolving credit facilities as of March 31, 2021, $150.0 million of borrowings as of March 31, 2020, and no borrowings under the senior secured revolving credit facilities as of December 31, 2020. Outstanding letters of credit under the senior secured revolving credit facilities totaled approximately $11 million, $13 million, and $11 million as of March 31, 2021, March 31, 2020, and December 31, 2020, respectively.
As of March 31, 2021, 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.

The Notes are guaranteed by Mattel’s existing and, subject to certain exceptions, future wholly owned domestic restricted subsidiaries that guarantee Mattel’s senior secured revolving credit facilities or certain other indebtedness.
The net proceeds from the offering, together with cash on hand, were used to redeem $1,225 million in aggregate principal amount of Mattel’s outstanding 6.750% Senior Notes due December 2025 (the "2025 Notes") and pay related prepayment premiums and transaction fees and expenses. As a result of the partial redemption of the 2025 Notes, Mattel incurred a loss on extinguishment of $83.2 million, comprised of $62.0 million of prepayment premium costs and a $21.2 million write-off of the unamortized debt issuance costs, which was recorded within interest expense in the consolidated statements of operations.

Currency Translation Adjustments
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 foreign 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 fiscal period-end exchange rates. Income and expense items are translated at weighted-average exchange rates prevailing during the fiscal period. The resulting currency translation adjustments are recorded as a component of accumulated other comprehensive loss within stockholders' equity. Currency translation adjustments resulted in a net loss of $28.1 million for the three months ended March 31, 2021, primarily due to the weakening of the Brazilian real, Mexican peso, Euro, and Turkish lira against the U.S. dollar. Currency translation adjustments resulted in a net loss of $145.6 million for the three months ended March 31, 2020, primarily due to the weakening of the Mexican peso, Russian ruble, Brazilian real, and British pound sterling against the U.S. dollar.

12. 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 (income) expense, net in the consolidated statements of operations in the period in which the currency exchange rate changes. Inventory transactions denominated in the Euro, Mexican peso, Australian dollar, British pound sterling, Canadian dollar, Russian ruble, and Brazilian real were the primary transactions that caused foreign currency transaction exposure for Mattel during the three months ended March 31, 2021.
Currency transaction gains (losses) included in the consolidated statements of operations are as follows:

13. Derivative Instruments
Mattel seeks to mitigate its exposure to foreign currency transaction risk by monitoring its foreign currency transaction exposure for the year and partially hedging such exposure using foreign currency forward exchange contracts. Mattel uses foreign currency forward exchange contracts as cash flow hedges primarily to hedge its purchases and sales of inventory denominated in foreign currencies. These contracts generally have maturity dates of up to 18 months. These derivative instruments have been designated as effective cash flow hedges, whereby the unsettled hedges are reported in Mattel's consolidated balance sheets at fair value, with changes in the fair value of the hedges reflected in other comprehensive income (loss) ("OCI"). Realized gains and losses for these contracts are recorded in the consolidated statements of operations in the period in which the inventory is sold to customers. 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. Mattel utilizes derivative contracts to hedge certain purchases of commodities, which were not material. As of March 31, 2021, March 31, 2020, and December 31, 2020, Mattel held foreign currency forward exchange contracts and other commodity derivative instruments, with notional amounts of $951.5 million, $1.37 billion, and $855.0 million, respectively.

14. Fair Value Measurements
The following tables present information about Mattel's assets and liabilities measured and reported in the financial statements at fair value on a recurring basis as of March 31, 2021, March 31, 2020, and December 31, 2020 and indicate the fair value hierarchy of the valuation techniques utilized to determine such fair value. The three levels of the fair value hierarchy are as follows:
•Level 1 – Valuations based on unadjusted quoted prices in active markets for identical assets or liabilities that the entity has the ability to access.
•Level 2 – Valuations based on quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable data for substantially the full term of the assets or liabilities, either directly or indirectly.
•Level 3 – Valuations based on inputs that are unobservable, supported by little or no market activity, and that are significant to the fair value of the assets or liabilities.

____________________________________________
(a)The fair value of the foreign currency forward exchange contracts and other commodity derivative instruments is based on dealer quotes of market forward rates and reflects the amount that Mattel would receive or pay at their maturity dates for contracts involving the same notional amounts, currencies, and maturity dates.
(b)The fair value of the available-for-sale security is based on the quoted price on an active public exchange.
Other Financial Instruments
Mattel's financial instruments include cash and equivalents, accounts receivable and payable, accrued liabilities, short-term borrowings, and long-term debt. The fair values of these instruments, excluding long-term debt, approximate their carrying values because of their short-term nature. Cash and equivalents are classified as Level 1 and all other financial instruments are classified as Level 2 within the fair value hierarchy.
The estimated fair value of Mattel's long-term debt was $3.05 billion (compared to a carrying value of $2.88 billion) as of March 31, 2021, $2.77 billion (compared to a carrying value of $2.90 billion) as of March 31, 2020, and $3.11 billion (compared to a carrying value of $2.90 billion) as of December 31, 2020. The estimated fair values have been calculated based on broker quotes or rates for the same or similar instruments and are classified as Level 2 within the fair value hierarchy.

_______________________________________
(a)Mattel was in a net loss position for the three months ended March 31, 2021 and 2020, and, accordingly, all outstanding nonqualified stock options and RSUs were excluded from the calculation of diluted net loss per common share because their effect would be antidilutive.
16. Employee Benefit Plans
Mattel and certain of its subsidiaries have qualified and nonqualified retirement plans covering substantially all employees of these companies, which are more fully described in Part II, Item 8 "Financial Statements and Supplementary Data—Note 4 to the Consolidated Financial Statements–Employee Benefit Plans" in the 2020 Annual Report on Form 10-K.

During the three months ended March 31, 2021, Mattel made cash contributions totaling approximately $1 million related to its defined benefit pension and postretirement benefit plans. During the remainder of 2021, Mattel expects to make additional cash contributions of approximately $16 million.
17. Share-Based Payments
Mattel has various stock compensation plans, which are more fully described in Part II, Item 8 "Financial Statements and Supplementary Data—Note 8 to the Consolidated Financial Statements—Share-Based Payments" in the 2020 Annual Report on Form 10-K. Under the Mattel, Inc. Amended and Restated 2010 Equity and Long-Term Compensation Plan, Mattel has the ability to grant nonqualified stock options, incentive stock options, stock appreciation rights, restricted stock, RSUs, performance awards, dividend equivalent rights, and shares of common stock to officers, employees, and other persons providing services to Mattel. Stock options are granted with exercise prices at the fair market value of Mattel's common stock on the applicable grant date and expire no later than ten years from the date of grant. Stock options, RSUs, and performance awards generally provide for vesting over, or at the end of, a period of three years from the date of grant.
As of March 31, 2021, three long-term incentive programs were in place with the following performance cycles: (i) a January 1, 2019–December 31, 2021 performance cycle, (ii) a January 1, 2020–December 31, 2022 performance cycle, and (iii) a January 1, 2021–December 31, 2023 performance cycle.
Compensation expense, included within other selling and administrative expenses in the consolidated statements of operations, related to stock options, RSUs, and performance awards is as follows:

| For the Three Months Ended |  |
| March 31, 2021 |  | March 31, 2020 |  |  |  |
| (In thousands)
Stock option compensation expense | $ | 2,783 |  |  | $ | 3,131 |  |  |  |  |
RSU compensation expense | 6,357 |  |  | 7,361 |  |  |  |  |
Performance award compensation expense | 5,972 |  |  | 3,783 |  |  |  |  |
| $ | 15,112 |  |  | $ | 14,275 |  |  |  |  |

As of March 31, 2021, total unrecognized compensation expense related to unvested share-based payments totaled $79.0 million and is expected to be recognized over a weighted-average period of 2.0 years.
Mattel uses treasury shares purchased under its share repurchase program to satisfy stock option exercises and the vesting of RSUs and performance awards. For the three months ended March 31, 2021, cash received for stock option exercises was $1.3 million. For the three months ended March 31, 2020, no cash was received for stock option exercises.

19. Restructuring Charges
Optimizing for Growth (formerly Capital Light)
On February 9, 2021, Mattel announced the Optimizing for Growth program, a multi-year cost savings program which integrates and expands upon the previously announced Capital Light program (the "Program").
19

In connection with the Program, Mattel recorded severance and other restructuring costs in the following cost and expense categories within the consolidated statements of operations:

| For the Three Months Ended |  |
| March 31, 2021 |  | March 31, 2020 |  |  |  |
| (In thousands)
Cost of sales (a) | $ | 1,932 |  |  | $ | 3,057 |  |  |  |  |
Other selling and administrative expenses (b) | 5,710 |  |  | 2,746 |  |  |  |  |
| $ | 7,642 |  |  | $ | 5,803 |  |  |  |  |

_______________________________________
(a)Severance and other restructuring costs recorded within cost of sales in the consolidated statements of operations include charges associated with the consolidation of manufacturing facilities.
(b)Severance and other restructuring costs recorded within other selling and administrative expenses in the consolidated statements of operations are included in corporate and other expense in "Note 22 to the Consolidated Financial Statements—Segment Information."
The following table summarizes Mattel's severance and other restructuring charges activity related to the Program for the three months ended March 31, 2021:

| Liability at December 31, 2020 |  | Charges (a) |  | Payments/Utilization |  | Liability at March 31, 2021
| (In thousands)
Severance | $ | 5,294 |  |  | $ | 4,342 |  |  | $ | (1,405) |  |  | $ | 8,231 |
Other restructuring charges | 30 |  |  | 3,300 |  |  | (3,071) |  |  | 259 |
| $ | 5,324 |  |  | $ | 7,642 |  |  | $ | (4,476) |  |  | $ | 8,490 |

_______________________________________
(a)Other restructuring charges consist primarily of charges associated with the consolidation of manufacturing facilities.
As of March 31, 2021, Mattel has recorded cumulative severance and other restructuring charges related to the Program of approximately $58 million, which include approximately $17 million of non-cash charges. Furthermore, cumulatively, in conjunction with previous actions taken under the Program, total expected cash expenditures are approximately $140 to $165 million and total non-cash charges are $40 to $45 million.
During the three months ended March 31, 2021, in conjunction with the Program, Mattel completed the sale of a manufacturing plant based in Mexico, which included land and buildings, resulting in a pre-tax gain of $15.8 million.
Other Cost Savings Actions
During the three months ended March 31, 2020, Mattel recorded severance charges of approximately $5 million, primarily related to actions taken to further streamline its organizational structure.
20. Income Taxes
Mattel's provision for income taxes was $20.3 million and $11.9 million for the three months ended March 31, 2021 and 2020, respectively. During the three months ended March 31, 2021, Mattel recognized a net discrete tax expense of $7.3 million, primarily related to income taxes recorded on a discrete basis in various jurisdictions and an expense for reassessments of prior year's tax liabilities. During the three months ended March 31, 2020, Mattel recognized a net discrete tax expense of $6.4 million primarily related to an expense for reassessments of prior years' tax liabilities and income taxes recorded on a discrete basis in various jurisdictions. As a result of the establishment of a valuation allowance on U.S. deferred tax assets in 2017, there was no U.S. tax benefit provided for U.S. losses during the three months ended March 31, 2021 and 2020.
20

Evaluating the need for and the amount of a valuation allowance for deferred tax assets often requires significant judgment and extensive analysis of all available evidence to determine whether it is more-likely-than-not that these assets will be realized. Mattel maintains a valuation allowance on its deferred tax assets until there is sufficient evidence to support the release of all or some portion of these allowances. Release of the valuation allowance would result in the recognition of a portion of these deferred tax assets and a decrease to income tax expense for the period the release is recorded. However, the exact timing and amount, if any, of the valuation allowance release are subject to change depending on the level of earnings that Mattel is able to achieve in the tax jurisdictions in which a valuation allowance has been recorded.
In the normal course of business, Mattel is regularly audited by federal, state, and foreign tax authorities. Based on the current status of federal, state, and foreign audits, Mattel believes it is reasonably possible that in the next twelve months, the total unrecognized tax benefits could decrease by approximately $31.6 million related to the settlement of tax audits and/or the expiration of statutes of limitations. The ultimate settlement of any particular issue with the applicable taxing authority could have a material impact on Mattel's consolidated financial statements.
21. Contingencies
Litigation Related to Yellowstone do Brasil Ltda.
Yellowstone do Brasil Ltda. (formerly known as Trebbor Informática Ltda.) was a customer of Mattel's subsidiary Mattel do Brasil Ltda. when a commercial dispute arose between Yellowstone and Mattel do Brasil regarding the supply of product and related payment terms. As a consequence of the dispute, in April 1999, Yellowstone filed a declarative action against Mattel do Brasil before the 15 th Civil Court of Curitiba – State of Parana (the "Trial Court"), requesting the annulment of its security bonds and promissory notes given to Mattel do Brasil as well as requesting the Trial Court to find Mattel do Brasil liable for damages incurred as a result of Mattel do Brasil’s alleged abrupt and unreasonable breach of an oral exclusive distribution agreement between the parties relating to the supply and sale of toys in Brazil. Yellowstone's complaint sought alleged loss of profits of approximately $1 million, plus an unspecified amount of damages consisting of: (i) compensation for all investments made by Yellowstone to develop Mattel do Brasil's business; (ii) reimbursement of the amounts paid by Yellowstone to terminate labor and civil contracts in connection with the business; (iii) compensation for alleged unfair competition and for the goodwill of trade; and (iv) compensation for non-pecuniary damages.
Mattel do Brasil filed its defenses to these claims and simultaneously presented a counterclaim for unpaid accounts receivable for goods supplied to Yellowstone in the approximate amount of $4 million.
During the evidentiary phase a first accounting report was submitted by a court-appointed expert. Such report stated that Yellowstone had invested approximately $3 million in its business. Additionally, the court-appointed expert calculated a loss of profits compensation of approximately $1 million. Mattel do Brasil challenged the report since it was not made based on the official accounting documents of Yellowstone and since the report calculated damages based only on documents unilaterally submitted by Yellowstone.
The Trial Court accepted the challenge and ruled that a second accounting examination should take place in the lawsuit. Yellowstone appealed the decision to the Court of Appeals of the State of Parana (the "Appeals Court"), but it was upheld by the Appeals Court.
The second court-appointed expert’s report submitted at trial did not assign a value to any of Yellowstone’s claims and found no evidence of causation between Mattel do Brasil's actions and such claims.
In January 2010, the Trial Court ruled in favor of Mattel do Brasil and denied all of Yellowstone’s claims based primarily on the lack of any causal connection between the acts of Mattel do Brasil and Yellowstone’s alleged damages. Additionally, the Trial Court upheld Mattel do Brasil's counterclaim and ordered Yellowstone to pay Mattel do Brasil approximately $4 million. The likelihood of Mattel do Brasil recovering this amount was uncertain due to the fact that Yellowstone was declared insolvent and filed for bankruptcy protection. In February 2010, Yellowstone filed a motion seeking clarification of the decision which was denied.
21

In September 2010, Yellowstone filed a further appeal with the Appeals Court. Under Brazilian law, the appeal was de novo and Yellowstone restated all of the arguments it made at the Trial Court level. Yellowstone did not provide any additional information supporting its unspecified alleged damages. The Appeals Court held hearings on the appeal in March and April 2013. On July 26, 2013, the Appeals Court awarded Yellowstone approximately $17 million in damages, plus attorney's fees, as adjusted for inflation and interest. The Appeals Court also awarded Mattel do Brasil approximately $7.5 million on its counterclaim, as adjusted for inflation. On August 2, 2013, Mattel do Brasil filed a motion with the Appeals Court for clarification since the written decision contained clear errors in terms of amounts awarded and interest and inflation adjustments. Mattel do Brasil's motion also asked the Appeals Court to decide whether Yellowstone’s award could be offset by the counterclaim award, despite Yellowstone's status as a bankrupt entity. Yellowstone also filed a motion for clarification on August 5, 2013. A decision on the clarification motions was rendered on November 11, 2014, and the Appeals Court accepted partially the arguments raised by Mattel do Brasil. As a result, the Appeals Court awarded Yellowstone approximately $14.5 million in damages, as adjusted for inflation and interest, plus attorney's fees. The Appeals Court also awarded Mattel do Brasil approximately $7.5 million on its counterclaim, as adjusted for inflation. The decision also recognized the existence of legal rules that support Mattel do Brasil's right to offset its counterclaim award of approximately $7.5 million. Mattel do Brasil filed a new motion for clarification with the Appeals Court on January 21, 2015, due to the incorrect statement made by the reporting judge of the Appeals Court, that the court-appointed expert analyzed the "accounting documents" of Yellowstone. On April 26, 2015, a decision on the motion for clarification was rendered. The Appeals Court ruled that the motion for clarification was denied and imposed a fine on Mattel do Brasil equal to 1% of the value of the claims made for the delay caused by the motion. On July 3, 2015, Mattel do Brasil filed a special appeal to the Superior Court of Justice based upon both procedural and substantive grounds. This special appeal sought to reverse the Appeals Court's decision of July 26, 2013, and to reverse the fine as inappropriate under the law. This special appeal was submitted to the Appeals Court.
Yellowstone also filed a special appeal with the Appeals Court in February 2015, which was made available to Mattel do Brasil on October 7, 2015. Yellowstone's special appeal sought to reverse the Appeals Court decision with respect to: (a) the limitation on Yellowstone's loss of profits claim to the amount requested in the complaint, instead of the amount contained in the first court-appointed experts report, and (b) the award of damages to Mattel do Brasil on the counterclaim, since the specific amount was not requested in Mattel do Brasil's counterclaim brief.
On October 19, 2015, Mattel do Brasil filed its answer to the special appeal filed by Yellowstone and Yellowstone filed its answer to the special appeal filed by Mattel do Brasil. On April 4, 2016, the Appeals Court rendered a decision denying the admissibility of Mattel's and Yellowstone's special appeals. On May 11, 2016, both Mattel and Yellowstone filed interlocutory appeals.
On August 31, 2017, the reporting justice for the Appeals Court denied Yellowstone’s interlocutory appeal. As to Mattel, the reporting justice reversed the fine referenced above that had been previously imposed on Mattel for filing a motion for clarification. However, the reporting justice rejected Mattel’s arguments on the merits of Yellowstone’s damages claims. On September 22, 2017, Mattel filed a further appeal to the full panel of five appellate justices to challenge the merits of Yellowstone's damages claims. Yellowstone did not file a further appeal.
In April 2018, Mattel do Brasil entered into a settlement agreement to resolve this matter, but the settlement was later rejected by the courts, subject to a pending appeal by Mattel.
On October 2, 2018, the Appeals Court rejected Mattel's merits appeal, and affirmed the prior rulings in favor of Yellowstone. In October 2019, Mattel reached an agreement with Yellowstone's former counsel regarding payment of the attorney's fees portion of the judgment. In November 2019, Yellowstone initiated an action to enforce its judgment against Mattel, but did not account for an offset for Mattel's counterclaim. On January 27, 2020, Mattel obtained an injunction, staying Yellowstone's enforcement action pending resolution of Mattel's appeal to enforce the parties' April 2018 settlement. As of March 31, 2021, Mattel assessed its probable loss related to the Yellowstone matter and has accrued a reserve, which was not material.
Litigation Related to the Fisher-Price Rock 'n Play Sleeper
A number of putative class action lawsuits are pending against Fisher-Price, Inc. and/or Mattel, Inc. asserting claims for false advertising, negligent product design, breach of warranty, fraud, and other claims in connection with the marketing and sale of the Fisher-Price Rock 'n Play Sleeper (the "Sleeper"). In general, the lawsuits allege that the Sleeper should not have been marketed and sold as safe and fit for prolonged and overnight sleep for infants. The putative class action lawsuits propose nationwide and over 15 statewide consumer classes comprised of those who purchased the Sleeper as marketed as safe for prolonged and overnight sleep. The class actions have been consolidated before a single judge for pre-trial purposes pursuant to the federal courts’ Multi-District Litigation program.
22

Forty-nine additional lawsuits are pending against Fisher-Price, Inc. and Mattel, Inc. alleging that a product defect in the Sleeper caused the fatalities of or injuries to fifty-three children. Additionally, Fisher-Price, Inc. and/or Mattel, Inc. have also received letters from lawyers purporting to represent additional plaintiffs who are threatening to assert similar claims.
In addition, a stockholder has filed a derivative action in the Court of Chancery for the State of Delaware (Kumar v. Bradley, et al., filed July 7, 2020) alleging breach of fiduciary duty and unjust enrichment related to the development, marketing, and sale of the Sleeper. The defendants in the derivative action are certain of Mattel's current and former officers and directors. In August 2020, the derivative action was stayed pending further developments in the class action lawsuits.
The lawsuits seek compensatory damages, punitive damages, statutory damages, restitution, disgorgement, attorneys’ fees, costs, interest, declaratory relief, and/or injunctive relief. Mattel believes that the allegations in the lawsuits are without merit and intends to vigorously defend against them.
A reasonable estimate of the amount of any possible loss or range of loss cannot be made at this time.
Litigation and Investigations Related to Whistleblower Letter
In December 2019 and January 2020, two stockholders filed separate complaints styled as class actions against Mattel, Inc., and certain of its current and former officers, alleging violations of federal securities laws. The complaints rely on the results of an investigation announced by Mattel in October 2019 regarding allegations in a whistleblower letter and claim that Mattel misled the market in several of its financial statements beginning in the third quarter of 2017. The lawsuits allege that the defendants' conduct caused the plaintiff and other stockholders to purchase Mattel common stock at artificially inflated prices.
In addition, a stockholder has filed a derivative action in the United States District Court for the District of Delaware (Moher v. Kreiz, et al., filed April 9, 2020) making allegations that are substantially identical to, or are based upon, the allegations of the class action lawsuits. The defendants in the derivative action are certain of Mattel's current and former officers and directors, Mattel, Inc., and PricewaterhouseCoopers LLP. Subsequently, a nearly identical derivative action was filed by a different stockholder against the same defendants. The second lawsuit is styled as an amended complaint and replaces a complaint making unrelated allegations in a previously filed lawsuit already pending in Delaware federal court (Lombardi v. Kreiz, et al., amended complaint filed April 16, 2020). In May 2020, the derivative actions were consolidated and stayed pending further developments in the class action lawsuits.
The lawsuits seek unspecified compensatory damages, attorneys' fees, expert fees, costs and/or injunctive relief. Mattel believes that the allegations in the lawsuits are without merit and intends to vigorously defend against them. A reasonable estimate of the amount of any possible loss or range of loss cannot be made at this time.
Mattel has also received subpoenas from the Securities and Exchange Commission (the "SEC"), seeking documents related to the whistleblower letter and subsequent investigation, and is responding to those subpoenas. Mattel is also responding to requests from the United States Attorney's Office for the Southern District of New York ("SDNY") related to this matter. Mattel cannot predict the eventual scope, duration or outcome of potential legal action by the SEC or SDNY, if any, or whether any such action could have a material impact on Mattel's financial condition, results of operations or cash flows.
22. Segment Information

23. New Accounting Pronouncements
Recently Adopted Accounting Pronouncements
In December 2019, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes, 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. The amendments related to changes in ownership of foreign equity method investments or foreign subsidiaries are applied on a modified retrospective basis through a cumulative effect adjustment to retained earnings as of the beginning of the fiscal year of adoption. The amendments related to franchise taxes that are partially based on income are 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 the beginning of the fiscal year of adoption. All other amendments are applied on a prospective basis. Mattel adopted ASU 2019-12 on January 1, 2021. The adoption of this new accounting standard did not have a material impact on Mattel's consolidated financial statements.
Accounting Pronouncements Not Yet Adopted
In March 2020 and January 2021, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting and ASU 2021-01, Reference Rate Reform (Topic 848): Scope, respectively. ASU 2020-04 and ASU 2021-01 provide optional expedients and exceptions for applying U.S. GAAP, to contracts, hedging relationships, and other transactions that reference the London Interbank Offered Rate or another reference rate expected to be discontinued because of reference rate reform, if certain criteria are met. The guidance in ASU 2020- 04 and ASU 2021-01 was effective upon issuance and, once adopted, may be applied prospectively to contract modifications and hedging relationships through December 31, 2022. Mattel is currently evaluating the impact of the adoption of ASU 2020-04 and ASU 2021-01 on its consolidated financial statements.

Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations.
In the discussion that follows, "Mattel" refers to Mattel, Inc. and/or one or more of its subsidiaries.
The following discussion should be read in conjunction with the consolidated financial statements and the related notes that appear in Part I, Item 1 "Financial Statements" of this Quarterly Report on Form 10-Q. Mattel's business is seasonal with consumers making a large percentage of all toy purchases during the traditional holiday season; therefore, results of operations are most comparable to corresponding periods.
The following discussion includes currency exchange rate impact, a non-GAAP financial measure within the meaning of Regulation G promulgated by the SEC ("Regulation G"), to supplement the financial results as reported in accordance with generally accepted accounting principles ("GAAP"). The currency exchange rate impact reflects the portion (expressed as a percentage) of changes in Mattel's reported results that are attributable to fluctuations in currency exchange rates. Mattel uses this non-GAAP financial measure to analyze its continuing operations and to monitor, assess, and identify meaningful trends in its operating and financial performance. Management believes that the disclosure of this non-GAAP financial measure provides useful supplemental information to investors to allow them to better evaluate ongoing business performance and certain components of Mattel's results. This measure is not, and should not be viewed as, a substitute for GAAP financial measures.
The following discussion also includes the use of gross billings, a key performance indicator. Gross billings represent amounts invoiced to customers. It does not include the impact of sales adjustments, such as trade discounts and other allowances. Mattel presents changes in gross billings as a metric for comparing its aggregate, categorical, brand, and geographic results to highlight significant trends in Mattel's business. Changes in gross billings are discussed because, while Mattel records the details of sales adjustments in its financial accounting systems at the time of sale, such sales adjustments are generally not associated with categories, brands, and individual products.
Effective as of the first quarter of 2021, operating income by segment reviewed by the Chief Operating Decision Maker does not include certain corporate expenses which were historically allocated by segment. The prior period presentation of operating income by segment has been conformed to the current period's presentation.
Note that amounts shown in millions within this Item 2 may not sum due to rounding.
Overview
Mattel is a leading global toy company and owner of one of the strongest catalogs of children’s and family entertainment franchises in the world, creating innovative products and experiences that inspire, entertain and develop children through play. Mattel is focused on the following two-part strategy to transform Mattel into an intellectual property ("IP") driven, high-performing toy company:
•In the short-term, improve profitability by optimizing operations and accelerate topline growth by growing Mattel's Power Brands and expanding Mattel's brand portfolio.
•In the mid-to-long-term, continue to make progress on capturing the full value of Mattel's IP through franchise management and online retail and e-commerce.
Mattel is the owner of a portfolio of iconic brands and partners with global entertainment companies to license other intellectual property. Mattel's owned and licensed brands and products are organized into the following categories:
Dolls—including brands such as Barbie, American Girl, Polly Pocket, Spirit (Universal) and Enchantimals. Mattel's Dolls portfolio is driven by the flagship Barbie brand and a collection of complementary brands offered globally. Empowering girls since 1959, Barbie has inspired the limitless potential of every girl by showing them that they can be anything. With an extensive portfolio of dolls and accessories, content, gaming, and lifestyle products, American Girl is best known for imparting valuable life lessons through its inspiring dolls and books, featuring diverse characters from past and present. Its products are sold directly to consumers via its catalog, website, and proprietary retail stores.
Infant, Toddler, and Preschool—including brands such as Fisher-Price and Thomas & Friends, Power Wheels, and Fireman Sam.

26

Vehicles—including brands such as Hot Wheels, Matchbox, CARS (Disney Pixar), and Mario Kart (Nintendo). In production for over 50 years, Hot Wheels continues to push the limits of performance and design, and ignites the challenger spirit of kids, adults, and collectors. From die-cast vehicles, to tracks, playsets, and accessories, the Mattel vehicles portfolio has broad appeal that engages and excites kids of all ages.
Action Figures, Building Sets, Games, and Other—including brands such as Masters of the Universe, MEGA, UNO, Toy Story (Disney Pixar), Jurassic World (NBCUniversal), WWE, and Star Wars (Disney). From big blocks to small bricks, first builders to advanced collectors, MEGA creates building sets that encourage kids and adults to unlock their creative potential. America's number one game, UNO is the classic matching card game that is easy to learn and fast fun for everyone.
COVID-19 Update
The impact of the coronavirus disease ("COVID-19") and the actions taken by governments, businesses, and individuals in response to it have resulted in significant global economic disruption, including, but not limited to, temporary business closures, reduced retail traffic, volatility in financial markets, and restrictions on travel.
Strong consumer demand for toys during the first quarter of 2021 contributed to double digit year-over-year increases in net sales across all reportable segments and in each geographic region, despite COVID-19 disruption and local restrictions that impacted certain locations. Mattel’s first quarter of 2020 results and net sales were significantly and negatively impacted by COVID-19.
Mattel's manufacturing and distribution network was fully operational as of March 31, 2021. To the extent COVID-19 causes manufacturing and distribution disruption, particularly during seasonally-high periods of production and/or distribution, Mattel’s ability to meet demand may be materially impacted. Due to the uncertainty of the duration and severity of the pandemic and resulting effects, it is not possible to estimate the extent of such impact.
Prolonged disruption to Mattel’s customers, supply chain, or other critical operations would result in material adverse effects to Mattel’s business and its liquidity. The future impact of COVID-19 on Mattel’s results of operations, financial position, and cash flows remains uncertain at this time due to rapidly evolving circumstances. Mattel is closely monitoring the situation and actively managing its business as developments occur. Refer to Part I, Item 1A "Risk Factors" in the 2020 Annual Report on Form 10-K for further discussion regarding potential impacts of COVID-19 on Mattel’s business.
The specific line items that have been materially affected by these impacts of COVID-19 are noted within "Results of Operations–First Quarter" below. In addition to the impacts of COVID-19 discussed below, it is reasonably likely that the pandemic and its resulting effects could have other unforeseen consequences that affect Mattel’s business.

28

Gross billings were $979.0 million in the first quarter of 2021, an increase of $309.0 million or 46%, as compared to $670.0 million in the first quarter of 2020, with a favorable impact from changes in currency exchange rates of one percentage point. The increase in first quarter of 2021 gross billings was primarily driven by higher billings of Dolls and Action Figures, Building Sets, Games, and Other.
Dolls gross billings increased 69%, of which 57% was due to higher billings of Barbie products, driven by positive brand momentum and point of sale demand ("POS") and 4% was due to higher billings of American Girl products.
Infant, Toddler, and Preschool gross billings increased 31%, all of which was due to higher billings of Fisher-Price and Thomas & Friends products, primarily driven by higher billings of infant and newborn products.
Vehicles gross billings increased 16%, of which 14% was due to higher billings of Hot Wheels products, driven by positive brand momentum and POS.
Action Figures, Building Sets, Games, and Other gross billings increased 69% due to higher billings from the following products: 15% from initial billings of Masters of the Universe, 15% from Jurassic World, 9% from WWE, 9% from plush, 8% from MEGA, and 7% from UNO.
Sales adjustments represent arrangements with Mattel’s customers to provide sales incentives, support customer promotions, and provide allowances for returns and 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. Sales adjustments as a percentage of net sales was relatively consistent at 12.0% for the first quarter of 2021, as compared to 12.8% for the first quarter of 2020.
Cost of Sales
Cost of sales as a percentage of net sales was 53.2% in the first quarter of 2021, as compared to 57.0% in the first quarter of 2020. Cost of sales increased by $126.3 million, or 37%, to $465.2 million in the first quarter of 2021 from $338.9 million in the first quarter of 2020, as compared to a 47% increase in net sales. Within cost of sales, product and other costs increased by $110.4 million, or 41%, to $380.0 million in the first quarter of 2021 from $269.6 million in the first quarter of 2020; freight and logistics expenses increased by $11.6 million, or 25%, to $57.4 million in the first quarter of 2021 from $45.8 million in the first quarter of 2020; and royalty expense increased by $4.3 million, or 18%, to $27.8 million in the first quarter of 2021 from $23.5 million in the first quarter of 2020. Within cost of sales, certain inbound freight costs were previously classified as freight and logistics costs. Mattel reclassified such inbound freight costs from freight and logistics expenses to present all inbound freight costs within product and other costs for the periods and segments presented.
Gross Margin
Gross margin increased to 46.8% in the first quarter of 2021 from 43.0% in the first quarter of 2020. The increase in gross margin was primarily driven by the favorable impact of fixed cost absorption and incremental realized savings from the cost savings programs, partially offset by input cost inflation due to higher raw material costs.
Advertising and Promotion Expenses
Advertising and promotion expenses primarily consist of: (i) media costs, which include the media, planning, and buying fees for television, print, and online advertisements, (ii) non-media costs, which include commercial and website production, merchandising, and promotional costs, (iii) retail advertising costs, which include consumer direct catalogs, newspaper inserts, fliers, and mailers and (iv) generic advertising costs, which include trade show costs. Advertising and promotion expenses as a percentage of net sales decreased to 8.5% in the first quarter of 2021 from 12.8% in the first quarter of 2020, primarily as a result of a slight decrease in advertising and promotion expense as compared to a 47% increase in net sales.
Other Selling and Administrative Expenses
Other selling and administrative expenses were $303.9 million, or 34.8% of net sales, in the first quarter of 2021, as compared to $328.7 million, or 55.3% of net sales, in the first quarter of 2020. The decrease in other selling and administrative expenses was primarily driven by a $15.8 million gain on sale of long-lived assets and incremental realized savings from the cost savings programs, partially offset by higher employee compensation costs.
29

Interest expense
Interest expense was $130.5 million for the first quarter of 2021, as compared to $49.0 million for the first quarter of 2020. The increase in interest expense was due to a loss on extinguishment of $83.2 million as a result of the partial redemption of the 2017/2018 Senior Notes due December 2025 in the first quarter of 2021.
Provision for Income Taxes
Mattel's provision for income taxes was $20.3 million and $11.9 million for the first quarter of 2021 and 2020, respectively. Mattel recognized net discrete tax expense of $7.3 million and $6.4 million for the first quarter of 2021 and 2020, respectively, primarily related to income taxes recorded on a discrete basis in various jurisdictions and an expense for reassessments of prior years' tax liabilities. As a result of the establishment of a valuation allowance on U.S. deferred tax assets, there was no U.S. tax benefit provided for U.S. losses during the first quarter of 2021 and 2020.
Mattel recorded a valuation allowance against certain domestic and foreign deferred tax assets as of both December 31, 2020 and March 31, 2021. Evaluating the need for and the amount of a valuation allowance for deferred tax assets often requires significant judgment and extensive analysis of all available evidence to determine whether it is more likely than not that these assets will be realized. Mattel maintains a valuation allowance on its deferred tax assets until there is sufficient evidence to support the release of all or some portion of these allowances. Given Mattel's improved earnings for the year ended December 31, 2020 and quarter ended March 31, 2021, and if, Mattel's earnings continue to improve in the future, Mattel believes that there is a reasonable possibility that in the near term, sufficient positive evidence may become available to allow us to reach a conclusion that a significant portion of the valuation allowance related to certain foreign jurisdictions will no longer be needed. Release of the valuation allowance would result in the recognition of a portion of these deferred tax assets and a decrease to income tax expense for the period the release is recorded. However, the exact timing and amount, if any, of the valuation allowance release are subject to change depending on the level of earnings that Mattel is able to achieve in the tax jurisdictions in which a valuation allowance has been recorded.

Gross billings for the American Girl segment were $46.3 million in the first quarter of 2021, an increase of $8.2 million, or 22%, as compared to $38.1 million in the first quarter of 2020. The increase in American Girl gross billings was primarily due to higher direct-to-consumer channel billings, partially offset by lower billings in proprietary retail channels.
Sales adjustments as a percentage of net sales was consistent at 2.5% for the first quarter of 2021 and 2020.
Cost of sales increased 21% in the first quarter of 2021, as compared to a 22% increase in net sales, primarily due to higher product and other costs and higher freight and logistics expenses. Gross margin in the first quarter of 2021 increased slightly due to incremental realized savings from cost savings programs, substantially offset by increased freight and logistics expenses due to higher direct-to-consumer channel sales. American Girl segment loss was $9.8 million in the first quarter of 2021, as compared to segment loss of $17.4 million in the first quarter of 2020. This improvement was primarily driven by higher gross profit and lower selling and administrative expenses due to the permanent closure of certain retail stores and renegotiated lease terms for certain retail stores.
Cost Savings Programs
Optimizing for Growth (formerly Capital Light)
On February 9, 2021, Mattel announced the Optimizing for Growth program, a multi-year cost savings program which integrates and expands upon the previously announced Capital Light program (the “Program”). Targeted annual gross cost savings from actions that are expected to be completed beginning 2021 through 2023 are $250 million. Of the $250 million in incremental targeted gross cost savings, approximately 50% is expected to benefit Cost of Sales, 40% to benefit Other Selling and Administrative Expenses, and 10% to benefit Advertising and Promotion Expense. Incremental cash expenditures associated with the Program are expected to be approximately $100 to $125 million.
Mattel estimates the cost of incremental actions for the Program to be as follows:

Optimizing for Growth - Incremental Actions | Estimate of Cost
Employee severance | $40 to $50 million
Real estate/supply chain optimization and other restructuring costs | $15 to $20 million
Asset impairments and other non-cash charges | $25 to $30 million
Total estimated severance and restructuring costs | $80 to $100 million
Information technology enhancements and other investments | $45 to $55 million
Total estimated incremental charges | $125 to $155 million

33

Cumulatively, in conjunction with previous actions taken under the Capital Light program, targeted annual gross cost savings for the Program are $325 million by 2023, with total expected cash expenditures of approximately $140 to $165 million, and total non-cash charges of $40 to $45 million. Of the $325 million in targeted gross cost savings, approximately 60% is expected to benefit Cost of Sales, 30% to benefit Other Selling and Administrative Expenses, and 10% to benefit Advertising and Promotion Expense.
In connection with the Program, Mattel has recorded severance and other restructuring costs in the following cost and expense categories within the consolidated statements of operations:

| For the Three Months Ended
| March 31, 2021 |  | March 31, 2020
| (In millions)
Cost of sales (a) | $ | 1.9 |  |  | $ | 3.1 |
Other selling and administrative expenses (b) | 5.7 |  |  | 2.7 |
| $ | 7.6 |  |  | $ | 5.8 |

(a)Severance and other restructuring costs recorded within cost of sales in the consolidated statements of operations are included in segment income (loss) in "Note 22 to the Consolidated Financial Statements—Segment Information."
(b)Severance and other restructuring costs recorded within other selling and administrative expenses in the consolidated statements of operations are included in corporate and other expense in "Note 22 to the Consolidated Financial Statements—Segment Information."
As of March 31, 2021, Mattel has recorded cumulative severance and other restructuring charges related to the Program of approximately $58 million , which include approximately $17 million of non-cash charges. Mattel realized cumulative cost savings (before severance, restructuring costs, and cost inflation) of approximately $102 million, primarily within gross profit, as of March 31, 2021 in connection with the Program.
During the three months ended March 31, 2021, in conjunction with the Program, Mattel completed the sale of a manufacturing plant based in Mexico, which included land and buildings, resulting in a pre-tax gain of $15.8 million.
Other Cost Savings Actions
During the three months ended March 31, 2020, Mattel recorded severance charges of approximately $5 million, primarily related to actions taken to further streamline its organizational structure.
Liquidity and Capital Resources
Mattel's primary sources of liquidity are its domestic and foreign cash and equivalents balances, short-term borrowing facilities, including its $1.40 billion senior secured revolving credit facilities, and access to capital markets to fund its operations and obligations. Such obligations may include investing and financing activities such as capital expenditures and debt service. Of Mattel's $615.2 million in cash and equivalents at March 31, 2021, approximately $588.3 million was held by foreign subsidiaries.
Cash flows from operating activities could be negatively impacted by decreased demand for Mattel's products, which could result from factors such as, but not limited to, adverse economic conditions and changes in public and consumer preferences, or by increased costs associated with manufacturing and distribution of products or shortages in raw materials or component parts. Additionally, Mattel's ability to issue long-term debt and obtain seasonal financing could be adversely affected by factors such as, but not limited to, global economic crises and tight credit environments, an inability to comply with its debt covenants and its senior secured revolving credit facilities covenants, or deterioration of Mattel's credit ratings. As discussed under Part I, Item 2 "Management’s Discussion and Analysis of Financial Condition and Results of Operations—COVID-19 Update" of this Quarterly Report on Form 10-Q, many of the aforementioned factors have been and may be adversely affected by COVID-19. However, based on Mattel’s current business plan and factors known to date, including the currently known impacts of COVID-19, it is expected that existing cash and equivalents, cash flows from operations, availability under the senior secured credit revolving facilities, and access to capital markets, will be sufficient to meet working capital and operating expenditure requirements for the next twelve months.
Current Market Conditions
Mattel is exposed to financial market risk resulting from changes in interest and foreign currency exchange rates.
34

Consistent with prior periods, Mattel intends to utilize its senior secured revolving credit facilities to meet its short-term liquidity needs. At March 31, 2021, Mattel had no outstanding borrowings under the senior secured revolving credit facilities and approximately $11 million in outstanding letters of credit under the senior secured revolving credit facilities.
Market conditions could affect certain terms of other debt instruments that Mattel enters into from time to time.
Mattel monitors the third-party depository institutions that hold Mattel's cash and equivalents. Mattel's emphasis is primarily on safety and liquidity of principal, and secondarily on maximizing the yield on those funds. Mattel diversifies its cash and equivalents among counterparties and securities to minimize risks.
Mattel is subject to credit risks relating to the ability of its counterparties in hedging transactions to meet their contractual payment obligations. The risks related to creditworthiness and nonperformance have been considered in the fair value measurements of Mattel's foreign currency forward exchange contracts. Mattel closely monitors its counterparties and takes action, as necessary, to manage its counterparty credit risk.
Mattel expects that some of its customers and vendors may experience difficulty in obtaining the liquidity required to buy inventory or raw materials. Mattel monitors its customers' financial condition and their liquidity in order to mitigate Mattel's accounts receivable collectability risks, and customer terms and credit limits are adjusted, if necessary. Additionally, Mattel uses a variety of financial arrangements to ensure collectability of accounts receivable of customers deemed to be a credit risk, including requiring letters of credit, factoring, purchasing various forms of credit insurance with unrelated third parties, or requiring cash in advance of shipment.
Mattel sponsors defined benefit pension plans and postretirement benefit plans for its employees. Actual returns below the expected rate of return, along with changes in interest rates that affect the measurement of the liability, would impact the amount and timing of Mattel's future contributions to these plans.
Mattel's business has been impacted by COVID-19. Refer to Part I, Item 2 "Management’s Discussion and Analysis of Financial Condition and Results of Operations—COVID-19 Update" for further discussion regarding the impact and potential impacts of COVID-19 on Mattel’s business.
Cash Flow Activities
Cash flows used for operating activities were $41.2 million in the first quarter of 2021, as compared to $174.5 million in the first quarter of 2020. The decrease in cash flows used for operating activities was primarily due to lower net loss, excluding the impact of non-cash charges.
Cash flows provided by investing activities were $6.3 million in the first quarter of 2021, as compared to cash flows used by investing activities of $81.2 million in the first quarter of 2020. The change in cash flows from investing activities was primarily driven by proceeds from the disposal of assets and a business of $39.2 million in the first quarter of 2021 and lower payments on foreign currency forward exchange contracts.
Cash flows used for financing activities were $105.7 million in the first quarter of 2021, as compared to cash flows provided by financing activities of $149.3 million in the first quarter of 2020. The change in cash flows from financing activities was driven primarily by the partial redemption of the 2017/2018 Senior Notes due December 2025 in the first quarter of 2021 and proceeds from short-term borrowings of $150.0 million in the first quarter of 2020.
Seasonal Financing
See Part I, Item 1 "Financial Statements—Note 8 to the Consolidated Financial Statements—Seasonal Financing" of this Quarterly Report on Form 10-Q.
35

Financial Position
Mattel's cash and equivalents decreased $146.9 million to $615.2 million at March 31, 2021, as compared to $762.2 million at December 31, 2020, due to seasonal working capital usage, the partial redemption of the 2017/2018 Senior Notes due December 2025, and capital expenditures. The decreases were partially offset by improved results of operations, excluding the impact of non-cash charges and proceeds from the disposal of assets and a business during the first quarter of 2021. Mattel's cash and equivalents increased $115.8 million to $615.2 million at March 31, 2021, as compared to $499.4 million at March 31, 2020, primarily due to cash flows from operating activities in the trailing twelve months, partially offset by capital expenditures, the partial redemption of the 2017/2018 Senior Notes due December 2025 in the first quarter of 2021 and repayment of short-term borrowings of $150.0 million outstanding as of March 31, 2020.
Accounts receivable decreased $353.3 million to $680.6 million at March 31, 2021, as compared to $1.03 billion at December 31, 2020, primarily due to seasonal declines as year-end receivables are collected. Accounts receivable increased $152.1 million to $680.6 million at March 31, 2021, as compared to $528.5 million at March 31, 2020, primarily due to higher net sales in the first quarter of 2021. Net sales in the first quarter of 2020 were negatively impacted by COVID-19.
Inventory increased $95.2 million to $609.8 million at March 31, 2021, as compared to $514.7 million at December 31, 2020, primarily due to seasonal inventory build. Inventory increased $49.2 million to $609.8 million at March 31, 2021, as compared to $560.6 million at March 31, 2020, due to increased production for higher anticipated sales in the second quarter of 2021 and the impact of foreign exchange.
Accounts payable and accrued liabilities decreased $275.7 million to $1.05 billion at March 31, 2021, as compared to $1.33 billion at December 31, 2020 due to seasonal declines in expenditure levels. Accounts payable and accrued liabilities increased $87.9 million to $1.05 billion at March 31, 2021, as compared to $963.7 million at March 31, 2020 due to increased payables associated with higher inventory production levels.
Mattel had $0.9 million, $150.0 million, and $1.0 million of short-term borrowings outstanding at March 31, 2021, March 31, 2020, and December 31, 2020 respectively. Mattel accelerated the timing of its borrowings under the senior secured revolving credit facilities during the first quarter of 2020 in anticipation of its projected seasonal working capital requirements and in light of uncertainties surrounding the impact of COVID-19.

The decrease is primarily due to the repayment of short-term borrowings of $150.0 million outstanding at March 31, 2020.

Stockholders' equity decreased $122.4 million to $473.9 million at March 31, 2021, as compared to $596.3 million at December 31, 2020, primarily due to the net loss for the first quarter of 2021. Stockholders' equity increased $316.0 million to $473.9 million at March 31, 2021, as compared to $157.9 million at March 31, 2020, primarily due to net income for the trailing twelve months.

New Accounting Pronouncements
See Part I, Item 1 "Financial Statements—Note 23 to the Consolidated Financial Statements—New Accounting Pronouncements" of this Quarterly Report on Form 10-Q.
Non-GAAP Financial Measure
To supplement the financial results presented in accordance with U.S. GAAP, Mattel presents a non-GAAP financial measure within the meaning of Regulation G promulgated by the SEC. The non-GAAP financial measure that Mattel presents is currency exchange rate impact. Mattel uses this measure to analyze its continuing operations and to monitor, assess, and identify meaningful trends in its operating and financial performance. Mattel believes that the disclosure of this non-GAAP financial measure provides useful supplemental information to investors to be able to better evaluate ongoing business performance and certain components of Mattel's results. This measure is not, and should not be viewed as, a substitute for GAAP financial measures and may not be comparable to similarly-titled measures used by other companies.
Currency Exchange Rate Impact
The currency exchange rate impact reflects the portion (expressed as a percentage) of changes in Mattel's reported results that are attributable to fluctuations in currency exchange rates.
For entities reporting in currencies other than the U.S. dollar, Mattel calculates the percentage change of period-over-period results at constant currency exchange rates (established as described below) by translating current period and prior period results using these rates. It then determines the currency exchange rate impact percentage by calculating the difference between the percentage change at such constant currency exchange rates and the percentage change at actual exchange rates.
The constant currency exchange rates are determined by Mattel at the beginning of each year and are applied consistently during the year. They are generally different from the actual exchange rates in effect during the current or prior period due to volatility in actual foreign exchange rates. Mattel considers whether any changes to the constant currency rates are appropriate at the beginning of each year. The exchange rates used for these constant currency calculations are generally based on prior year actual exchange rates.
Mattel believes that the disclosure of the percentage impact of foreign currency changes is useful supplemental information for investors to be able to gauge Mattel's current business performance and the longer-term strength of its overall business since foreign currency changes could potentially mask underlying sales trends. The disclosure of the percentage impact of foreign exchange allows investors to calculate the impact on a constant currency basis and also enhances their ability to compare financial results from one period to another.
Key Performance Indicator
Gross billings represent amounts invoiced to customers. It does not include the impact of sales adjustments, such as trade discounts and other allowances. Mattel presents changes in gross billings as a metric for comparing its aggregate, categorical, brand, and geographic results to highlight significant trends in Mattel's business. Changes in gross billings are discussed because, while Mattel records the details of sales adjustments in its financial accounting systems at the time of sale, such sales adjustments are generally not associated with categories, brands, and individual products.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.
Foreign Currency Exchange Rate Risk
Currency exchange rate fluctuations impact Mattel's results of operations and cash flows. Inventory transactions denominated in the Euro, Mexican peso, Australian dollar, British pound sterling, Canadian dollar, Russian ruble, and Brazilian real were the primary transactions that caused foreign currency transaction exposure for Mattel during the first quarter of 2021. Mattel seeks to mitigate its exposure to market risk by monitoring its foreign currency transaction exposure for the year and partially hedging such exposure using foreign currency forward exchange contracts primarily to hedge its purchase and sale of inventory and other intercompany transactions denominated in foreign currencies. These contracts generally have maturity dates of up to 18 months. For those intercompany receivables and payables that are not hedged, the transaction gains or losses are recorded in the consolidated statements of operations in the period in which the exchange rate changes as part of operating income (loss) or other non-operating (income) expense, net based on the nature of the underlying transaction. Transaction gains or losses on hedged intercompany inventory transactions are recorded in the consolidated statements of operations in the period in which the inventory is sold to customers. In addition, Mattel manages its exposure to currency exchange rate fluctuations through the selection of currencies used for international borrowings. Mattel does not trade in financial instruments for speculative purposes.
Mattel's financial position is also impacted by currency exchange rate fluctuations on translation of its net investments in subsidiaries with non-U.S. dollar functional currencies. Assets and liabilities of subsidiaries with non-U.S. dollar functional currencies are translated into U.S. dollars at fiscal period-end exchange rates. Income, expense, and cash flow items are translated at weighted-average exchange rates prevailing during the fiscal period. The resulting currency translation adjustments are recorded as a component of accumulated other comprehensive loss within stockholders' equity. Mattel's primary currency translation adjustments for the first quarter of 2021 were related to its net investments in entities having functional currencies denominated in the Brazilian real, Mexican peso, Euro, and Turkish lira.
There are numerous factors impacting the amount by which Mattel's financial results are affected by foreign currency translation and transaction gains and losses resulting from changes in currency exchange rates, including, but not limited to, the level of foreign currency forward exchange contracts in place at a given time and the volume of foreign currency-denominated transactions in a given period. However, assuming that such factors were held constant, Mattel estimates that a 1 percent change in the U.S. dollar Trade-Weighted Index would have impacted Mattel's first quarter net sales by approximately 0.4% and have no impact to Mattel's net loss per share.
United Kingdom Operations
During June 2016, the referendum by British voters to exit the EU ("Brexit") adversely impacted global markets and resulted in a sharp decline of the British pound sterling against the U.S. dollar. In February 2017, the British Parliament voted in favor of allowing the British government to begin the formal process of Brexit and discussions with the EU began in March 2017. On January 29, 2020, the British Parliament approved a withdrawal agreement, and the United Kingdom ("U.K.") officially withdrew from the EU on January 31, 2020 and entered into a transition period that ended on December 31, 2020.
On December 24, 2020, the U.K. and EU agreed upon The EU-UK Trade and Cooperation Agreement. The agreement was provisionally applicable beginning January 1, 2021 and sets new rules and arrangements between the U.K. and EU in areas such as the trade of goods and services, intellectual property, transportation, and more. As a result of the agreement, the U.K. is no longer considered a member of the EU Single Market and Customs Union and exited all EU policies and trade agreements. The transfer of goods between the U.K. and EU is subject to additional inspections and checkpoints causing possible delays in the movement of inventory. Although the agreement has mitigated a portion of the risk that arose due to the U.K.'s withdrawal from the EU, the overall impact on Mattel's operations is still being evaluated, including the volatility of the British pound sterling. Mattel's U.K. operations represented approximately 5% of Mattel's consolidated net sales for the three months ended March 31, 2021.

Item 4. Controls and Procedures.
Evaluation of Disclosure Controls and Procedures
As of March 31, 2021, Mattel’s disclosure controls and procedures were evaluated, with the participation of Mattel’s principal executive officer and principal financial officer, to assess whether they are effective in providing reasonable assurance that information required to be disclosed by Mattel in the reports that it files or submits under the Securities Exchange Act of 1934, as amended, is accumulated and communicated to management, including its principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure and to provide reasonable assurance that such information is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission's rules and forms. Based on this evaluation, Ynon Kreiz, Mattel’s principal executive officer, and Anthony DiSilvestro, Mattel’s principal financial officer, concluded that these disclosure controls and procedures were effective to provide reasonable assurance as of March 31, 2021.
Changes in Internal Control over Financial Reporting
There were no changes in internal control over financial reporting that occurred during the quarter ended March 31, 2021 that have materially affected, or are reasonably likely to materially affect, Mattel’s internal control over financial reporting.
