Natures of estimates and assumptions

Pension costs and obligations are dependent on assumptions used in calculating such amounts. These assumptions include discount rates, benefits earned, interest costs, expected rate of return on plan assets, mortality rates and other factors. Actual results that differ from the assumptions are accumulated and amortized over future periods and, therefore, generally affect recognized expense in future periods. While management believes that the assumptions used are appropriate, differences in actual experience or changes in assumptions may affect Toyota’s pension costs and obligations.

The two most critical assumptions impacting the calculation of pension costs and obligations are the discount rates and the expected rates of returns on plan assets. Toyota determines the discount rates mainly based on the rates of high quality fixed income bonds or fixed income governmental bonds currently available and expected to be available during the period to maturity of the defined benefit pension plans. Toyota determines the expected rates of return for pension assets after considering several applicable factors including, the composition of plan assets held, assumed risks of asset management, historical results of the returns on plan assets, Toyota’s principal policy for plan asset management, and forecasted market conditions. A weighted-average discount rate of 2.8% and a weighted-average expected rate of return on plan assets of 3.6% are the results of assumptions used for the various pension plans in calculating Toyota’s consolidated pension costs for fiscal 2009. Also, a weighted-average discount rate of 2.8% is the result of assumption used for the various pension plans in calculating Toyota’s consolidated pension obligations for fiscal 2009.

Actual results that differ from the assumptions are accumulated and amortized over future periods and, therefore, generally affect recognized expense and the recorded obligations in future periods.
