Check the appropriate box below if the Form 8-K filing is intended to simultaneously satisfy the filing obligation of the registrant under any of the following provisions:

On February 28, 2012, pursuant to the Mattel, Inc. (“Mattel”) Guidelines Concerning Rule 10b5-1(c) Individual Trading Plans (the “Guidelines”), the following individuals entered into separate individual Rule 10b5-1(c) trading plans (individually, a “Plan,” and collectively, the “Plans”) with a broker to sell shares of Mattel stock acquired upon exercise of employee stock options (the “Options”) or to sell net shares of Mattel stock acquired upon the settlement of deferred restricted stock units. The Options have a ten year term and will expire in 2013, 2015 or 2016. The 685,468 deferred restricted stock units were granted to Robert Eckert, our former Chief Executive Officer, on May 16, 2000 pursuant to the terms of his employment agreement (the “Deferred RSUs”). The first 514,101 Deferred RSUs, less shares to satisfy tax withholding, will be settled on April 1, 2012 and the remaining 171,367 Deferred RSUs, less shares to satisfy tax withholding, will be settled on June 30, 2012. In accordance with Mattel’s Guidelines, the first sales under the Plans may not take place until April 2, 2012, which is at least 30 days after the date each executive adopted his or her Plan:

The transactions under each Plan will be disclosed publicly in accordance with the requirements of Form 144 and Form 4 filings with the Securities and Exchange Commission. Each Plan was adopted in accordance with Rule 10b5-1 of the Securities Exchange Act of 1934, as amended, and with Mattel’s Guidelines.

Rule 10b5-1 permits individuals who are not in possession of material, non-public information at the time the plan is adopted to establish pre-arranged plans to buy or sell company stock. Using these plans, individuals can gradually diversify their investment portfolios over an extended period of time and better manage the exercise of stock options or the sale of shares.
