The fair market value of the Trust’s Assigned royalty interests was not determined in 1888 when the Trust was formed, and accordingly, the Assigned royalty interests were recorded with no value. See Note 2, “Summary of Significant Accounting Policies — Real Estate and Royalty Interests Assigned Through the Declaration of Trust” for further information regarding the Assigned royalty interests. The Assigned royalty interests include 1/16th and 1/128th royalty interests.
