Recently Adopted and Not Yet Adopted Accounting Pronouncements

Recently Adopted Accounting Pronouncements

In July 2025, the FASB issued ASU 2025-05, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets. ASU 2025-05 provides the option to apply a practical expedient to address implementation challenges related to the estimation of expected credit losses for current accounts receivable and current assets arising from transactions accounted for under revenue recognition (Topic 606) and assets acquired through business combinations. The practical expedient allows entities to assume that current conditions as of the balance sheet date remain unchanged over the life of these assets when developing forecasts. The guidance allows entities to bypass the requirement to incorporate macro-economic data into their forecast when such data is not expected to materially affect the estimate. Mattel adopted the guidance in ASU 2025-05 effective January 1, 2026 prospectively and applied the practical expedient. 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 November 2024, the FASB issued ASU 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses for public business entities. ASU 2024-03 requires enhanced disclosures of each expense caption in the income statement to improve transparency and provide financial statement users with more detailed information about the nature, amount and timing of expenses impacting financial performance. Additionally, in January 2025, the FASB issued ASU 2025-01 to clarify the effective date of ASU 2024-03. The guidance in ASU 2024-03 is effective for fiscal years beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027. Early adoption is permitted. The ASU may be applied either (1) prospectively to financial statements issued for reporting periods after the effective date of this ASU or (2) retrospectively to all prior periods presented in the financial statements. Mattel is currently evaluating the impact of the adoption of ASU 2024-03 on its consolidated financial statements.

In September 2025, the FASB issued ASU 2025-06, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software. ASU 2025-06 modernizes certain aspects of the accounting for software costs to develop or obtain software for internal use under Accounting Standards Codification 350-40. The ASU requires entities to begin capitalizing software costs when management authorizes and commits to funding the software project, and it is probable that the project will be completed and the software will be used for its intended purpose. The guidance in ASU 2025-06 is effective for fiscal years beginning after December 15, 2027, and interim periods within those fiscal years. Early adoption is permitted. The amendments in ASU 2025-06 permit entities to apply the new guidance using a prospective, retrospective, or modified transition approach. Mattel is currently evaluating the impact of the adoption of ASU 2025-06 on its consolidated financial statements.
