The Company believes that the long-term asset allocations on average will approximate the targeted
allocations and regularly reviews the actual asset allocations to periodically rebalance the investments to
the targeted allocations when appropriate. The target asset allocations are established with the objective
of achieving the plans’ expected return on assets without undue investment risk.
Expected 2009 contributions are $10 million for the pension plans and $158 million for the other
postretirement benefit plans. The following benefit payments are expected to be made in future years for
