Because they were asked to
A little something about how they work.
There could a number of reason, why they would need it, but it sounds a lot like they are trying to expand (build new factories etc.)
What does international sales with in the last 5-10 years and labour costs have to do with each other?
Their retail pricing was just homogenized, so they cost the same all over the world, which they didn't 5+ years ago. The large difference in msrp., showed their hand, which really wasn't a good idea, as some buyers f.x. in Europe would feel ripped of paying double of what the US or Canada payed.
