Longevity risk

Definition

Longevity risk refers to the potential financial uncertainty that arises when individuals live longer than expected, impacting the sustainability of retirement plans and pensions. This risk is particularly relevant for defined benefit plans, which promise a certain payout for life, as it can lead to higher-than-anticipated liabilities. It also affects valuation of pension assets and liabilities, requiring careful consideration of mortality improvements and demographic trends to ensure adequate funding.

5 Must Know Facts For Your Next Test

1. Longevity risk increases as advancements in healthcare and technology improve life expectancy, leading to more individuals collecting pensions for longer periods.
2. Defined contribution plans transfer longevity risk from the employer to the employee, as these plans do not guarantee lifetime payouts.
3. Pension plans must regularly update mortality tables to reflect current life expectancy trends in order to accurately assess their liabilities.
4. Financial strategies, such as longevity insurance or annuities, can be used to mitigate longevity risk by providing guaranteed income for life.
5. Regulatory requirements may mandate pension plans to hold sufficient reserves to cover projected liabilities, directly linking longevity risk with financial stability.

Review Questions

• How does longevity risk affect the funding requirements of defined benefit plans?
  • Longevity risk impacts defined benefit plans by increasing the financial obligations that these plans must meet as members live longer than anticipated. When retirees outlive their expected lifespan, pension funds may need to pay benefits for extended periods, leading to higher-than-expected liabilities. This situation requires pension funds to maintain adequate funding levels and perform regular actuarial assessments to ensure they can meet their future obligations.
• In what ways do mortality improvements influence the valuation of pension liabilities?
  • Mortality improvements significantly affect the valuation of pension liabilities by altering assumptions about how long retirees will draw benefits. As life expectancy increases due to healthcare advancements, actuaries must adjust their mortality tables accordingly, which can raise the estimated costs associated with pension payouts. This adjustment necessitates that pension funds reassess their investment strategies and reserves to align with the updated projections for longevity risk.
• Evaluate the effectiveness of various strategies in mitigating longevity risk within retirement planning.
  • Mitigating longevity risk within retirement planning involves employing strategies like purchasing annuities, which provide guaranteed income for life, thus protecting retirees from outliving their savings. Another effective method is integrating longevity insurance into financial portfolios, which kicks in after a certain age, offering an additional layer of security against prolonged lifespans. Employers can also consider offering hybrid plans that combine features of both defined benefit and defined contribution plans, distributing the longevity risk more evenly between the employer and employees while ensuring that retirees have some level of guaranteed income.
