There are multiple types of Puerto Rico Assignment of Overriding Royalty Interest for Multiple Leases, each varying based on the specific lease and interest details. The following are key types: 1. Fixed Percentage ORRIS Assignment: This type specifies a fixed percentage that the assignee will receive as their overriding royalty interest, irrespective of any existing leasehold burdens. 2. Percentage Reduction ORRIS Assignment: In this type, the assignee's overriding royalty interest is determined by subtracting a specified percentage from the existing leasehold burdens. For example, if the specified percentage is 10% and the existing leasehold burdens are 5%, then the assignee's ORRIS would be 5%. 3. Standard Differential ORRIS Assignment: This type calculates the overriding royalty interest in taking the difference between the specified percentage and the total existing leasehold burdens. For instance, if the specified percentage is 12.5% and the existing leasehold burdens amount to 7.5%, then the assignee would receive an ORRIS of 5%. 4. Proportional Allocation ORRIS Assignment: This type allocates the overriding royalty interest based on a proportionate distribution of the specified percentage and the existing leasehold burdens. The assignee's ORRIS is determined by dividing the existing burdens by the sum of the specified percentage and the burdens, and then multiplying it by the specified percentage. For example, if the specified percentage is 15% and the existing leasehold burdens are 10%, the assignee's ORRIS would be (10% / (15% + 10%)) * 15% = 60%.
