Goodwill Policy	Mattel tests its goodwill for impairment annually in the third quarter, and whenever events or changes in circumstances indicate that the carrying amount may exceed its fair value.
Foreign Currency Translations	Mattel’s reporting currency is the US dollar. The translation of its net investment in subsidiaries with non-US dollar functional currencies subjects Mattel to currency exchange rate fluctuations in its results of operations and financial position. Assets and liabilities of subsidiaries with non-US dollar functional currencies are translated into US 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.
Derivatives, Policy	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 (“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. Additionally, Mattel uses foreign currency forward exchange contracts to hedge intercompany loans and advances denominated in foreign currencies. Due to the short-term nature of the contracts involved, Mattel does not use hedge accounting for these contracts, and as such, changes in fair value are recorded in the period of change in the consolidated statements of operations
Earnings Per Share Policy	Unvested share-based payment awards that contain nonforfeitable rights to dividends or dividend equivalents (whether paid or unpaid) are participating securities and are included in the computation of earnings per share pursuant to the two-class method. Certain of Mattel’s restricted stock units (“RSUs”) are considered participating securities because they contain nonforfeitable rights to dividend equivalents. Under the two-class method, net income is reduced by the amount of dividends declared in the period for each class of common stock and participating securities. The remaining undistributed earnings are then allocated to common stock and participating securities as if all of the net income for the period had been distributed. Basic earnings per common share excludes dilution and is calculated by dividing net income allocable to common shares by the weighted average number of common shares outstanding for the period. Diluted earnings per common share is calculated by dividing net income allocable to common shares by the weighted average number of common shares for the period, as adjusted for the potential dilutive effect of non-participating share-based awards.
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 to which they relate in the consolidated statements of operations. For hedges of intercompany loans and advances, which do not qualify for hedge accounting treatment, the gains or losses on the hedges resulting from changes in fair value as well as the offsetting transaction gains or losses on the related hedged items, along with unhedged items, are recognized in non-operating income (expense), net in the consolidated statements of operations.
Segment Reporting, Policy	Mattel does not include sales adjustments such as trade discounts and other allowances in the calculation of segment revenues (referred to as “gross sales”). Mattel records these adjustments in its financial accounting systems at the time of sale to each customer, but the adjustments are not allocated to individual products. For this reason, Mattel’s CODM uses gross sales by segment as one of the metrics to measure segment performance. Such sales adjustments are included in the determination of segment income from operations based on the adjustments recorded in the financial accounting systems. Segment income represents each segment’s operating income, while consolidated operating income represents income from operations before net interest, other non-operating income, and income taxes as reported in the consolidated statements of operations. The corporate and other expense category includes costs not allocated to individual segments, including charges related to incentive compensation, share-based payments, and corporate headquarters functions managed on a worldwide basis, and the impact of changes in foreign currency rates on intercompany transactions.

Mattel tests its goodwill for impairment annually in the third quarter, and whenever events or changes in circumstances indicate that the carrying amount may exceed its fair value.

Foreign Currency Translations

Mattel’s reporting currency is the US dollar. The translation of its net investment in subsidiaries with non-US dollar functional currencies subjects Mattel to currency exchange rate fluctuations in its results of operations and financial position. Assets and liabilities of subsidiaries with non-US dollar functional currencies are translated into US 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.

Derivatives, Policy

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

Certain of Mattel’s restricted stock units (“RSUs”) are considered participating securities because they contain nonforfeitable rights to dividend equivalents.

Under the two-class method, net income is reduced by the amount of dividends declared in the period for each class of common stock and participating securities.
