Supplemental Indenture

On May 31, 2018, Mattel, Inc. (the “Company” or the “Issuer”) issued $500.0 million aggregate principal amount of its 6.750% Senior Notes due 2025 (the “New Notes”). The New Notes were issued pursuant to a supplemental indenture, dated as of May 31, 2018 (the “Supplemental Indenture”), to the Indenture, dated as of December 20, 2017 (the “Base Indenture” and, together with the Supplemental Indenture, the “Indenture”), among the Issuer, the guarantors named therein and MUFG Union Bank, N.A., as Trustee. The New Notes were offered in a private placement to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”), and to certain non-U.S. persons in transactions outside of the United States in reliance on Regulation S under the Securities Act.

The New Notes are treated as a single series of debt securities with the Issuer’s previously issued $1,000.0 million aggregate principal amount of 6.750% Senior Notes due 2025 (the “Existing Notes” and, together with the New Notes, the “Notes”) for all purposes under the Indenture, including, without limitation, waivers, amendments, redemptions and offers to purchase. The New Notes have terms identical to the Existing Notes, other than issue date and offering price and have the same CUSIP and ISIN numbers as, and trade together with, the Existing Notes, except that the New Notes sold pursuant to Regulation S have been issued and maintained under a temporary CUSIP number during a 40-day distribution period commencing on May 31, 2018.

The foregoing summary of the Supplemental Indenture is qualified in its entirety by reference to the actual text of the Supplemental Indenture, a copy of which is filed herewith as Exhibit 4.1.

The net proceeds from the offering, plus cash on hand, will be used to redeem and retire all of the Issuer’s outstanding 2.350% Notes due 2019 and pay related prepayment premiums and transaction fees and expenses.

First Amendment to Syndicated Facility Agreement

On June 1, 2018, the Company entered into an amendment (the “Amendment”) to the Syndicated Facility Agreement, dated as of December 20, 2017 (the “Existing Credit Agreement” and the Existing Credit Agreement, as amended by the Amendment, the “Credit Agreement”), among the Company, as a borrower and guarantor thereunder, certain of the Company’s domestic and foreign subsidiaries, as additional borrowers and/or guarantors thereunder, Bank of America, N.A., as global administrative agent, collateral agent and Australian security trustee, and the other lenders and financial institutions party thereto.

The Amendment amends certain terms of the Existing Credit Agreement, including, but not limited to, the maturity date thereof. Each of the facilities under the Credit Agreement will now mature, and lending commitments thereunder will now terminate, on June 1, 2021.

The foregoing summary of the Amendment is qualified in its entirety by reference to the actual text of the Amendment, a copy of which is filed herewith as Exhibit 10.1.

Section 2 – Financial Information

The information set forth under “Supplemental Indenture” in Item 1.01 above is incorporated by reference into this Item 2.03.

On May 31, 2018, the Company issued an irrevocable notice of redemption to holders of its 2.350% Notes due 2019 (the “2019 Notes”) for the redemption of all $500 million outstanding aggregate principal amount of the 2019 Notes. The redemption date for the 2019 Notes will be June 30, 2018. The redemption price for the 2019 Notes will be calculated in accordance with the indenture governing the 2019 Notes and will be equal to the greater of (1) 100% of the principal amount of the 2019 Notes being redeemed plus accrued and unpaid interest to, but excluding, the redemption date or (2) a “Make-Whole Amount” (as defined in the indenture governing the 2019 Notes) for the 2019 Notes being redeemed.
