$1\mathrm{.}2\%\backslash$times Service years $\backslash$times Final year$$s salary

Stanley Mills was hired by Clark at the beginning of $2002.$ Mills is expected to retire at the end of $2046$ after $45$ years of service. His retirement is expected to span $15$ years. At the end of $2021,20$ years after being hired, his salary is $$87,000.$ The company$$s actuary projects Mills$$s salary to be $$340,000$ at retirement. The actuary$$s discount rate is $6\%.($FV of $$1,$ PV of $$1,$ FVA of $$1,$ PVA of $$1,$ FVAD of $$1$ and PVAD of $$1)($Use appropriate factor$($s$)$ from the tables provided.$)$

Required:

$1.$ Estimate the amount of Stanley Mills$$s annual retirement payments for the $15$ retirement years earned as of the end of $2021.$

$2.$ Suppose Clark$$s pension plan permits a lump$-$sum payment at retirement in lieu of annuity payments. Determine the lump$-$sum equivalent as the present value as of the retirement date of annuity payments during the retirement period.

$3.$ What is the company$$s projected benefit obligation at the end of $2021$ with respect to Stanley Mills?

$4.$ Even though pension accounting centers on the PBO calculation, the ABO still must be disclosed in the pension disclosure note. What is the company$$s accumulated benefit obligation at the end of $2021$ with respect to Stanley Mills?

$5.$ If we assume no estimates change in the meantime, what is the company$$s projected benefit obligation at the end of $2022$ with respect to Stanley Mills?

$6.$ What portion of the $2022$ increase in the PBO is attributable to $2022$ service $($the service cost component of pension expense$)$ and to accrued interest $($the interest cost component of pension expense$)?$
