It's actually measured in a number of ways. Are we accessing new markets from yesterday? Are we basically solidifying our global competitive position in those new markets? Are we producing more value from the forests?
I've mentioned that we're a $57-billion industry today. I'm just looking straight, on straight value, and actually, a couple of years ago we were a $53-billion industry. As you've heard, we're aspiring to reach an additional $20 billion, which is based on two years ago, so that's a $74-billion industry.
One way to track it is, and this is publicly available information, what's our economic activity looking like in the sector over time? How is our competitive position in markets vis-à-vis...? We operate in a very competitive global marketplace. It's very interesting in the forest industry. We're very rurally based. We access the globe.
