In 20X5-X6, the plan was amended to provide additional benefits with effect from 1 April 20X5. The present value as at 1 April 20X5 of additional benefits for employee service before 1 April 20X5 was Rs. 50 for vested benefits and Rs. 30 for non-vested benefits. As at 1 April 20X5, the enterprise estimated that the average period until the non-vested benefits would become vested was three years; the past service cost arising from additional non-vested benefits is therefore recognised on a straight-line basis over three years. The past service cost arising from additional vested benefits is recognised immediately (paragraph 94 of the Standard).
