On January 24, 2011, Alcoa contributed newly issued shares (see Note K) of its common stock (valued at $600) to a master trust that holds the assets of certain U.S. defined benefit pension plans in a private placement transaction. These shares were issued to satisfy the estimated minimum required funding and to provide additional funding towards maintaining an approximately 80% funded status of Alcoa's U.S. pension plans.
