Other metrics we’re developing will also link our marketing
activities to the top line. One will measure the price premium
we enjoy relative to our competitors because of our
segment-tailored value propositions and superior execution.
Comparing our average prices at year’s end to certain competitors
in each country is our current first proxy. By this
crude measure, Lafarge *** is lagging its competitors *** (by $7 per
tonne compared with Holcim and $2 per tonne versus
Cemex).We believe, however, that ***their higher prices ***reflect
the different geographic mix of the markets they operate
in, and we suspect that the difference would be a lot greater
if we had not undertaken our marketing initiatives.

Kompletnie nie rozumiem tego fragmentu.
W drugim zdaniu mowa o tym, że Lafarge zamierza porównywać "premium prices we enjoy" czyli wyższe ceny w stosunku do konkurencji. Potem mowa, że Lafarge "is lagging its competitors" (zostawia konkurentów w tyle, czy zostaje w tyle za konkurencją?),.
Ale potem mowa, że "their higher prices", czyli ceny konkurentów Cemex i Holcim są wyższe.
