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
historical returns, as well as actuarial recommendations using the most current generational and mortality tables and
rates.
The Company develops the rate of compensation increase assumptions using local compensation practices and
historical rates of increases.
Plan Assets
Investment Policies and Strategies
The investment policy in Japan is to generate a stable return on investments over a long-term horizon in order to
have adequate pension funds to meet the Company's future obligations. In order to achieve this investment goal, a
diversified portfolio with target asset allocation and expected rate of return is established by considering factors such
as composition of participants, level of funded status, capacity to absorb risks, and the current economic environment.
The target asset allocation is 22% to 35% in equity securities, 46% to 62% in debt securities and the remaining 3%
to 32% in other assets. Risk management is accomplished through diversification, periodic review of plan asset
