It should be 70.

IFRS is a smoothed number, so remember under IFRS, it will be a smaller number compared to the number under US GAAP, which is the net funded status. Hence, more volatile reporting under US GAAP because small movements in the components of Plan Assets or PBO cause big movements in the funded status.

So intuitively, if the plan is overfunded (assets>PBO), it will be a smaller (+) number
if the plan is underfunded (PBO<assets), it will be a smaller (-) number

Now, back to the equations and formulas -
if it's a cost: add back
if it's a gain: subtract
to get a smooth number for IFRS

Hope this helps
