One of the things that I think is dogma within venture capital is that you don't want to manage what they call the "living dead." I don't know what the numbers are now, but back when I was working with venture capitalists, their rules of thumb were: typically one out of ten companies is a really big hit; roughly three out of ten go belly up pretty quickly, and you get rid of them. The other five to six are what they call the "living dead." They grow nicely, organically, but don't generate spectacular returns, and they take management time and energy. Those are the kinds of companies they prefer not to deal with, because it simply doesn't make sense. They have a fiduciary responsibility to their limited partners to generate a significant return, so they want to deal with firms that will tend to do that.
