You need to add Employer Contributions to exclude its effect on periodic cost, thereby increasing PPC (because this is a cost to the employer, regardless of change in funded status).
In this example, CFAI is representing a cost as a negative number, so subtracting a positive has the affect of increasing your PPC, which is ultimately what you want to reflect.
The text is a bit confusing, but understanding the concept above is the important part, then you can apply the formula and numbers as appropriate.
Ya the tricky part comes from the funded status. If the plan because more funded (IE change in funded status increases) then your TPPC will decrease. If your plan becomes less funded (IE change in funded status decreases) your TPPC will increase.
If you understand what TPPC is then all you need to remember is the two parts - Contributions and Funded Status and how the affect TPPC, dont even think about the formula. Thats how I approach all material in the CFA if you need to “memorize” the formula, study it unitl you dont.
Think of it this way: if the value of your pension assets and pension liability don’t change (perhaps you gave your workers the year off, and earned nothing on the assets), and you contributed $10, then your cost is $10: add the contribution.
I can tell you that this is incorrect: Total PPC = End Fund Status - Beg Fund Status + Contributions
If Beginning Funded Status was -$3000
End Funded Status went to - $3020
And Contributions were $1000
Your formula would read TPPC = -3020 - (-3000) + 1000 = 980
the correct answer would be TPPC = 1000 - (-3020 - -3000) = 1020…
This example is from CFAI EOC #9 page 213… solution is on page 217 and reads as follows…
“9 B is correct. The total periodic pension cost is the change in the net pension liability adjusted for the employer’s contribution into the plan. The net pension liability increased from 3,000 to 3,020, and the employer’s contribution was 1,000. The total periodic pension cost is 1,020.” (Institute 217) Institute, CFA. CFA Institute Level II 2014 Volume 2 Financial Reporting and Analysis. John Wiley & Sons P&T, 2013-07-12. VitalBook file. CFAI’s description of the formula can be found on page 198…
And that’s probably where the confusion on this thread is stemming from… It’s easiest for me to remember TPPC = Contributions - (Change in funded status)
where: Contributions is entered as a positive number.
To each their own… I was probably in the wrong by claiming his formula was incorrect without knowing how he input the signs on each number… my bad
We treat PPC as a negative number if the result is positive (since it increases net pension liability) and vice versa: we treat PPC as a positive number if the result is negative (since it decreases net pension liability).
And the result stems from the following formula: Contributions - (End FS - Begin FS)
