The parent company and subsidiaries in Japan have severance indemnity plans and non-contributory defined benefit funded pension plans, or only severance indemnity plans, covering substantially all of their employees who meet eligibility requirements of the retirement regulations. Under the plans, employees whose service with the company is terminated are, under most circumstances, entitled to lump-sum severance indemnities and/or pension payments, determined by reference to current basic rate of pay, length of service and conditions under which the termination occurs. The funding policy is to make contributions that can be deducted for Japanese income tax purposes.
The parent company and certain subsidiaries in Japan also have contributory defined benefit pension plans, covering substantially all of their employees, including the governmental welfare pension benefit plan which shall be otherwise provided by the Japanese government. The pension benefits are determined based on years of service and the compensation amount as stipulated in the regulations. The governmental welfare pension contributions are funded in conformity with the requirements regulated by the Japanese Welfare Pension Insurance Law. The contributions to the contributory and the non-contributory pension plans are funded with trusteed pension funds.
Most subsidiaries outside Japan have various retirement plans covering substantially all of their employees, which are primarily defined contribution plans. The funding policy for the defined contribution plans is annually to contribute an amount equal to a certain percentage of the participants' annual salaries.
The combined funded status of the defined benefit pension plans and the severance indemnity plans at March 31, 1994 and 1995 was as follows:
