Attributing Benefit to Periods of Service

68. In determining the present value of its defined benefit obligations
and the related current service cost and, where applicable, past service
cost, an enterprise should attribute benefit to periods of service under the
plan’s benefit formula. However, if an employee’s service in later years
will lead to a materially higher level of benefit than in earlier years, an
enterprise should attribute benefit on a straight-line basis from:

(a) the date when service by the employee first leads to benefits
under the plan (whether or not the benefits are conditional on
further service); until

(b) the date when further service by the employee will lead to no
material amount of further benefits under the plan, other than
from further salary increases.

69. The Projected Unit Credit Method requires an enterprise to attribute
benefit to the current period (in order to determine current service cost)
and the current and prior periods (in order to determine the present value
of defined benefit obligations). An enterprise attributes benefit to periods
in which the obligation to provide post-employment benefits arises. That
obligation arises as employees render services in return for post-
employment benefits which an enterprise expects to pay in future
reporting periods. Actuarial techniques allow an enterprise to measure
that obligation with sufficient reliability to justify recognition of a
liability.

Examples Illustrating Paragraph 69

1. A defined benefit plan provides a lump-sum benefit of Rs. 100
payable on retirement for each year of service.

A benefit of Rs. 100 is attributed to each year.The current service
cost is the present value of Rs. 100. The present value of the
defined benefit obligation is the present value of Rs. 100,
multiplied by the number of years of service up to the balance
sheet date.

If the benefit is payable immediately when the employee leaves
the enterprise, the current service cost and the present value of
