Since K2 OWNS Line, why would they copy essentially from themselves? If they copy Line's product, the profit still goes to them. It's smart to keep the company the way it is, people really like it and because of that they buy from them. If people buy from K2, K2 makes money. If people buy from Line, K2 still makes money. So there's no need to copy their product since it's already theirs.
Basically think of K2 investing in Line....not owning it.
