Actuarial Cost Method Flashcards
How many salary increases between 65-n and 65 if we use current year salary? Prior year Salary?
Current Year Salary is n-1
Prior Year Salary is n
How does ax relate to ax+1 ?
Does the relationship change for a temporary annuity?
Either:
- ax = 1 + vpxax+1
- ax+1 = (ax - 1) * (1+i)/px
Doesn’t change for a temporary annuity
ePVFSt+1
(PVFS - salary) x (1 + i) * (1 + s’)/(1 + s)
What would the PVFS adjustment factor be if there is no experience Gain/Loss and salary scale is s’ instead of s?
(PVFS - salary) x (1 + i) * (1 + s’)/(1 + s)
i.e. adjustment factor of (1 + s’)/(1 + s)
eSalaryt+1
px(T)*(1+s)*(Salaryt)
UAL
AAL - AVA
Actuarial Accrued Liability - Actuarial Value of Assets
ePVFBt+1
PVFB * (1 + i) - (Actual BPs + int)
What is the adjustment factor for the PVFB if there was no experience G/L, but
- salary increased by s’, not s
- Benefit rate was $20 per month instead of $18 per month
(1 + s’)/(1 + s)
$20/$18
When projecting PVFB, do you project service for determining elegibility? For calculating the benefit amount?
Project Service for both
Expected UAL at t+1
eUALt+1 = (UALt + NC)*(1 + i) - C - I
C - Contribution Made
I - Interest made on the Contribution
eAALt+1
Note: 3 items - (NC, IC, BP)
eAALt+1 = (1+i)(NCt+AALt) - (actual BP + int)
For the AAL, do you project service to calculate elegibility?
Do you project service to calculate the benefit amount?
Project Service for Eligibility
Don’t project service to calculate benefit.
For investment gain/loss, do you use the MVA or AVA?
AVA
eAssetst+1
eAssetst+1 = (1 + i) * Assetst + (Contributions + int) - (BP + int)
Note use the actual BPs because actual assets use actual BPs and we simply want the difference in investment G/L
Actuarial Gain/Loss
eUALt+1 - UALt+1
AAL - Retrospective Method
AAL = the sum of all past Normal Costs accumulated with Interest/Mortality
AAL - Prospective Method
PVFB - PVFNC Present Value of Future Benefits - Present Value of Future Normal Costs
What is the difference between Projected Unit Credit and Traditional Unit Credit
PUC projects forward the Salary
Unit Credit AAL
- Calculate the accrued benefit at NRA
- Multiply by annuity factor to get PV at NRA
- Using interest/mortality discount back to valuation date
In formula form, this means:
(ABx+1 - ABx)*ara*(Dra/Dx) or (ABx+1 - ABx)*ara*(vra-x ra-xpx)
Unit Credit Normal Cost
- Calculate the change in the accrued benefit at NRA
- Multiply by annuity factor to get PV at NRA
- Using interest/mortality discount back to valuation date
In formula form, this means:
ABx*ara*(Dra/Dx) or ABx*ara*(vra-x ra-xpx)
T/F If a participant is 100% vested, the withdrawal assumption does not affect the AAL under the Unit Credit Method.
True
T/F if there are no G/L and we use Level $ funding where applicable, the normal cost does not change under all funding methods.
False - Under Unit Credit it would
PTP is hired in 2003 and the plan starts in 2006, when is the entry age for the EAN Actuarial Cost Method?
2003
Entry Age is determined without regard to whether the plan was in existence.
