Lifetime Pension or Commuted Value? An Actuarial Analysis

Lifetime Pension or take your money and run?  Canadian Defined Benefit plan members nearing retirement will face the following question:  Lifetime Pension or Commuted Value? Should I draw my pension income directly from my company’s pension plan, or should I take the commuted value and invest it outside of the plan? 
The answer is not as easy as it sounds. 

Lifetime Pension or Commuted Value?

Members who terminate from defined benefit pension plans (DB Plans) are generally provided the choice of either:

  • Receiving a lifetime pension from the DB Plan, or
  • A lump sum commuted value (CV) of their pension entitlement.

Such members often ask us at GBL “Which option is better: Lifetime Pension or Commuted Value?”

This article shows how this seemingly “simple” question has no simple answer.  The classification of “better” is a matter of probability.  Choosing one option results in financial risk to the member relative to selecting the other option. 

Actuarial analysis is key in better understanding the pension-related risks and resulting financial trade-offs.  Determining which pension option is “better” for the member is a risk management exercise regarding the member’s entire financial/retirement plan.  To properly manage this risk, the member should consider working with a financial/retirement planner with the actuarial analysis of the pension option as one of the many tools.

What a CV is, and More Importantly, What a CV Isn’t

In simple terms, a CV is the lump sum amount that would need to be invested today, which along with assumed investment income, would provide for the expected future pension payments that would have otherwise been paid to the member from the DB Plan.

A key element in the above description is “expected future pension payments”.  The word “expected” implies probabilities.  It is not known how long the member and/or spouse will live, therefore mortality probabilities are applied.  The CV is a probability-weighted average of the amount that would need to be invested to provide for the future lifetime(s).  The amount that is actually needed could be substantially more if the lifetimes are longer than average, or substantially less if the lifetimes are shorter than average.

Rolling the Mortality Dice

Consider an analogy: An individual is playing a game where they would receive $1,000 x the roll of a pair of dice.  In this game, they would receive anywhere from $2,000 to $12,000 with varying probabilities.  Instead of playing this game, they are offered a CV of $7,000 (the average payout).  Which is better, playing the game or taking the CV? 

Taking the CV instead of playing the game:

  • Is a great choice if they otherwise were to roll a 2 or 3 (or only live to age 70 or 72).
  • Is a terrible choice if they otherwise were to roll an 11 or 12 (or live to age 95 or 100 or longer)
  • Is slightly to moderately better or worse depending on the outcomes of rolling the dice (with these other outcomes making up the highest probabilities of outcomes)

A pension CV is often misinterpreted as being able to provide a drawdown of the pension income for the remainder of the member’s/spouse’s lifetimes.  It isn’t!  Even if the other assumptions used in determining the CV (such as investment returns and inflation rates) are exactly matched in future experience, the equivalent pension drawdown would only continue until the assets were depleted.  In rough terms, there would be about a 50% chance of the assets being depleted prior to deaths of the member and spouse, and about a 50% chance of the member and spouse both dying prior to the depletion of assets leaving an asset for the estate.

The following table indicates the tradeoffs:

Mortality OutcomeTaking Lifetime PensionTaking CV
If member/spouse both die several years before average life expectancyRisk is that there is no (or very little) estate value in this scenarioNo risk – There would likely be substantial assets remaining from the drawdown of the CV for the estate
If either member or spouse live for several years longer than average life expectancyNo risk – pension and/or survivor pension would continue until death, regardless how long member or spouse livesRisk is that investment from CV would have been depleted and provide no continuing pension
If death of the survivor of the member or spouse is within a few years of their life expectancy.Not a material deviation – pension would continue for the lifetime of the member and likely no estate value.Not a material deviation – there might be little estate value left over, or the assets might have been depleted for a short period.*

* Although the value of the risk in this specific mortality scenario is limited, there is a very substantial stress-related risk at the time the assets are approaching depletion.  Specifically, it is not usually known in advance that the mortality outcome will be in this category, rather than the scenario where survival of either the member or spouse continues substantially longer than average.

The Benefit of the Customized Actuarial Analysis:

In performing the actuarial analysis we reflect:

  • Actual details regarding the options:
    • Lifetime retirement pension option:  The pension commencement date, joint & survivor payment option, guarantee periods, bridge benefits, and cost of living adjustment provisions
    • CV option:  The amount of the CV including the amount that can be tax-sheltered in a LIRA and the amount that must be taken as a taxable lump sum payment
  • Assumptions from the member and/or their financial advisor on (i) expected future investment returns after investment expenses, and the standard deviation of such investment performance, (ii) for pensions with cost of living adjustments, details on expected future inflation rates and standard deviation of such future inflation to reflect, and (iii) general issues on mortality probabilities and adjustments to standard mortality life expectancy that should be reflected.
  • Details on expected taxable income in the future to reflect appropriate income tax rates in the projection.

Reflecting the Preceding Information, Our Analysis Projects:

  • The present value of the pension under the customized assumptions compared to the CV determined by the plan administrator.
  • A reconciliation of this difference in value.
  • The probability of being able to draw down the after-tax pension payments from the investment of the CV without running out of assets prior to death of the member/spouse.
  • In the portion of cases where assets are not depleted, the average asset balance at death of the last of the member/spouse to die.
  • In the portion of cases where assets are depleted, the average period of time of survival that no assets were available, and the average amount of additional CV that would have been required to not have a shortfall.
  • A graph showing the range of outcomes based on mortality probabilities under different investment-return assumptions.
  • A graph showing range of risk (in general the CV has a much greater chance of not running out of assets in the scenarios where death is earier than average, and a much greater chance of running out of assets where death is later than average)
  • A determination of how much of the difference between the present value of the pension payments, related to the commuted value, is a result of assuming risk in the investment portfolio.
  • Information on the mortality probabilities, so that planning can be performed to reflect a future timeframe to limit the probability of outliving assets to specified minimums.
  • General information on many other considerations that should be reviewed as part of the overall financial plan favouring either the CV or the lifetime pension.

Lifetime Pension or Commuted Value? Don’t Leave it to a Game of Chance

Plan members are advised not to play a game of chance with this important decision.  The decision to take the lifetime pension or CV has consequences; sometimes considerable.  For those Defined Benefit plan members nearing retirement and wondering if they should take the lifetime pension or take their CV money and run, GBL can complete an actuarial analysis will outline the probabilities and expected outcomes of both options.  This will help those plan members optimize their decision for themselves and their families.
