Again, as I said earlier, it's one thing to invest in technology and be granted or accorded kudos by the community for your technology. It's another thing to commercialize the technology. In order to do that, you need people willing to buy the technology.
It became pretty apparent to us over the last 12 months that while our major customer operators really appreciated our technology and what we had done, given our situation as Nortel, they were not prepared to purchase this technology from us.
