Debt Disclosure [Abstract]
Seasonal Financing	Seasonal Financing On September 15, 2022, Mattel entered into a revolving credit agreement (the "Credit Agreement") as the borrower with Bank of America, N.A., as administrative agent, and the other lenders and financial institutions party thereto, providing for a senior secured revolving credit facility in an aggregate principal amount of $1.40 billion (the "Revolving Credit Facility"). The Revolving Credit Facility will mature on September 15, 2025. In connection with the entry into the Credit Agreement, Mattel terminated the commitments and satisfied all outstanding obligations under the previous credit agreement, dated December 20, 2017 (as amended). Borrowings under the Revolving Credit Facility bear interest at a floating rate, which can be either, at Mattel's option, (i) adjusted Term Secured Overnight Financing Rate ("SOFR") plus an applicable margin ranging from 1.125% to 2.000% per annum or (ii) an alternate base rate plus an applicable margin ranging from 0.125% to 1.000% per annum, in each case, such applicable margins to be determined based on Mattel's debt ratings. In addition to paying interest on the outstanding principal under the Revolving Credit Facility, Mattel is required to pay (i) an unused line fee per annum of the average daily unused portion of the Revolving Credit Facility; (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. In November 2022, Moody's upgraded Mattel's debt rating from Ba1 to Baa3, and in April 2023, S&P upgraded Mattel's debt rating from BB+ to BBB- and maintained a positive outlook. On April 27, 2023 (the "Fall-Away Date"), Mattel provided a certification of the foregoing to the administrative agent under the Credit Agreement, which resulted in certain subsidiary guarantees, liens, covenants, and other restrictions falling away under the Credit Agreement. The obligations of Mattel under the Revolving Credit Facility were previously guaranteed by each domestic subsidiary of Mattel that guaranteed any of Mattel's senior unsecured notes (collectively, the "Guarantors"). On the Fall-Away Date, the foregoing guarantees were released and the obligations of Mattel under the Revolving Credit Facility are instead required to be guaranteed by each existing and future direct and indirect domestic subsidiary of Mattel only to the extent such subsidiary guarantees other indebtedness of Mattel in an aggregate principal or committed amount in excess of $50 million. The Revolving Credit Facility was previously secured by liens on substantially all of Mattel's and the Guarantors' present and after-acquired assets (subject to certain exceptions), including domestic accounts receivable, inventory, certain trademarks and patents, and certain equity interests in direct material subsidiaries of Mattel and the Guarantors, but all such liens were permanently released on the Fall-Away Date. The Credit Agreement contains customary covenants (subject to customary exceptions), including, but not limited to, restrictions on Mattel's and its subsidiaries' ability to merge and consolidate with other companies, incur indebtedness, grant liens or security interests on assets, sell or otherwise dispose of assets, or amend organizational documents. The Credit Agreement requires the maintenance of (a) an interest coverage ratio of not less than 2.75 to 1.00 as of the end of each fiscal quarter and (b) a total leverage ratio not to exceed 3.75 to 1.00 as of the end of each fiscal quarter. As of June 30, 2023, Mattel had no borrowings outstanding under the Revolving Credit Facility and no other short-term borrowings outstanding. As of June 30, 2022, Mattel had no borrowings outstanding under the previous senior secured revolving credit facilities and $3.0 million of other short-term borrowings outstanding. As of December 31, 2022, Mattel had no borrowings outstanding under the Revolving Credit Facility and no other short-term borrowings outstanding. Outstanding letters of credit under the Revolving Credit Facility totaled approximately $8 million as of June 30, 2023. Outstanding letters of credit under the previous senior secured revolving credit facilities totaled approximately $9 million as of June 30, 2022. Outstanding letters of credit under the Revolving Credit Facility totaled approximately $8 million as of December 31, 2022. As of June 30, 2023, Mattel was in compliance with all covenants contained in the Credit Agreement. The Credit Agreement is a material agreement, and failure to comply with its covenants may result in an event of default under the terms of the Revolving Credit Facility. If Mattel were to default under the terms of the Revolving Credit Facility, its ability to meet its seasonal financing requirements could be adversely affected.
