Attributing benefits to years of service
1. A defined benefit plan provides a lump-sum benefit of 100 payable on retirement for each year of service.
A benefit of 100 is attributed to each year. The current service cost is the present value of 100. The present value of the defined benefit obligation is the present value of 100, multiplied by the number of years of service up to the end of the reporting period.
If the benefit is payable immediately when the employee leaves the entity, the current service cost and the present value of the defined benefit obligation reflect the date at which the employee is expected to leave. Thus, because of the effect of discounting, they are less than the amounts that would be determined if the employee left at the end of the reporting period.
2. A plan provides a monthly pension of 0.2% of final salary for each year of service. The pension is payable from the age of 65.
Benefit equal to the present value, at the expected retirement date, of a monthly pension of 0.2% of the estimated final salary payable from the expected retirement date until the expected date of death is attributed to each year of service. The current service cost is the present value of that benefit. The present value of the defined benefit obligation is the present value of monthly pension payments of 0.2% of final salary, multiplied by the number of years of service up to the end of the reporting period. The current service cost and the present value of the defined benefit obligation are discounted because pension payments begin at the age of 65.
3. A plan pays a benefit of 100 for each year of service. The benefits vest after ten years of service.
A benefit of 100 is attributed to each year. In each of the first ten years, the current service cost and the present value of the obligation reflect the probability that the employee may not complete ten years of service.
4. A plan pays a benefit of 100 for each year of service, excluding service before the age of 25. The benefits vest immediately.
No benefit is attributed to service before the age of 25 because service before that date does not lead to benefits (conditional or unconditional). A benefit of 100 is attributed to each subsequent year.
5. A plan pays a lump-sum benefit of 1,000 that vests after ten years of service. The plan provides no further benefit for subsequent service.
A benefit of 100 (1,000 divided by ten) is attributed to each of the first ten years. The current service cost in each of the first ten years reflects the probability that the employee may not complete ten years of service. No benefit is attributed to subsequent years.
6. A plan pays a lump-sum retirement benefit of 2,000 to all employees who are still employed at the age of 55 after twenty years of service, or who are still employed at the age of 65, regardless of their length of service.
For employees who join before the age of 35, service first leads to benefits under the plan at the age of 35 (an employee could leave at the age of 30 and return at the age of 33, with no effect on the amount or timing of benefits). Those benefits are conditional on further service. Also, service beyond the age of 55 will lead to no material amount of further benefits. For these employees, the entity attributes benefit of 100 (2,000 divided by 20) to each year from the age of 35 to the age of 55.
For employees who join between the ages of 35 and 45, service beyond twenty years will lead to no material amount of further benefits. For these employees, the entity attributes benefit of 100 (2,000 divided by 20) to each of the first twenty years.
For an employee who joins at the age of 55, service beyond ten years will lead to no material amount of further benefits. For this employee, the entity attributes benefit of 200 (2,000 divided by 10) to each of the first ten years.
For all employees, the current service cost and the present value of the obligation reflect the probability that the employee may not complete the necessary period of service.
7. A post-employment medical plan reimburses 40% of an employee’s post-employment medical costs if the employee leaves after more than ten and less than twenty years of service and 50% of those costs if the employee leaves after twenty or more years of service.
Under the plan’s benefit formula, the entity attributes 4% of the present value of the expected medical costs (40% divided by ten) to each of the first ten years and 1% (10% divided by ten) to each of the second ten years. The current service cost in each year reflects the probability that the employee may not complete the necessary period of service to earn part or all of the benefits. For employees expected to leave within ten years, no benefit is attributed.
8. A post-employment medical plan reimburses 10% of an employee’s post-employment medical costs if the employee leaves after more than ten and less than twenty years of service and 50% of those costs if the employee leaves after twenty or more years of service.
Service in later years will lead to a materially higher level of benefit than in earlier years. Therefore, for employees expected to leave after twenty or more years, the entity attributes benefit on a straight-line basis under paragraph 68 of the standard. Service beyond twenty years will lead to no material amount of further benefits. Therefore, the benefit attributed to each of the first twenty years is 2.5% of the present value of the expected medical costs (50% divided by twenty).
For employees expected to leave between ten and twenty years, the benefit attributed to each of the first ten years is 1% of the present value of the expected medical costs. For these employees, no benefit is attributed to service between the end of the tenth year and the estimated date of leaving.
For employees expected to leave within ten years, no benefit is attributed.
9. Employees are entitled to a benefit of 3% of final salary for each year of service before the age of 55.
Benefit of 3% of estimated final salary is attributed to each year up to the age of 55. This is the date when further service by the employee will lead to no material amount of further benefits under the plan. No benefit is attributed to service after that age.
