Essentially, I'll answer your question about geoscience and our data banks and so on. The geoscience information is public, and so it is very much in the public domain—and we, in fact, do it so that companies can use it. It's one of the unique features of this country that we actually do, making it available for anybody, to stimulate investment.
I'm going to ask Ginny to try to answer your first question, and we'll see if there's time for the royalties question.
