In previous posts, we have discussed the relationship between public royalty interests and their market pricing implications to royalty owners. Here, we will define our group of royalty interests which can be used to gain valuation insights. Specifically, we will look at mineral aggregators, natural gas focused trusts, and crude oil focused trusts and the statutory differences between them. We also consider how dividend yields and other public data can be used to imply value for private mineral interests while being judicious in our application of such metrics.
