Employee benefits expense
Employee benefit expense consists of financial costs associated with pension and health care budgets. Our employee benefit expense increased 31.9% to U.S.$595 million for 2003, as compared to U.S.$451 million for 2002. This rise in costs was attributable to an increase of U.S.$166 million from the annual actuarial calculation of our pension and health care plan liability. The increase was partially offset by the effect of the 5.2% decrease in the value of the Real against the U.S. dollar in 2003, as compared to 2002.
