The Company develops a discount rate by calculating when the estimated benefit payments will be due. Manage-
ment in Japan then matches the benefit payments to AA or higher bond ratings that match the timing of the expected
benefit payments to determine the appropriate discount rate.
The Company develops the expected long-term rate of return on plan assets by analyzing rates of return in Japan
as well as the investment portfolio applicable to the plan. Management's estimates of future rates of return on assets is
based in large part on the projected rate of return from the respective investment managers using a long-term view of

rates.
The Company develops the rate of compensation increase assumptions using local compensation practices and
