LNK Cost Base

I'll obviously get proper financial advice (not that they are always right either). But thoughts on those that own LNK, I should probably post there too

So the cost base for PXA is $11.92 and LNK is $1.89, I obviously bought LNK before the PXA spin off.

say you bought LNK at $4 would I calculate my purchase cost base as "4 x 0.5444 = $2.217" as my cost base - (and then say I'm rich!)
