They attribute tens of millions of dollars to inventory movement in the 2013 report which is deducted from cost of sales. But the words "inventory movement" have not been used once in their last 3 years of annual reports and yet they decide not to explain even briefly what inventory movement includes in the whole of a 200 page document. Commmmooooon PDN, man you're making it hard for me to invest in you.

From the business dictionary, inventory movement is: An inventory classification for items that are held due to a process delay while some inventory is moved from one location to another.

I guess this is what it means for PDN too, but who knows, and in what context?
