Alaska Assignment of Overriding Royalty Interests (ORRIS) is a contractual agreement in the oil and gas industry that allows an assignor to transfer a portion of their net revenue interest to an assignee. This assignment typically occurs after deducting certain costs, thereby providing the assignee with a share in the net profits generated from the oil and gas production in Alaska. The ORRIS can vary in terms of the percentage assigned, as well as the specific costs deducted. Different types of Alaska Assignment of Overriding Royalty Interests include: 1. Fixed Percentage Assignment: This type of assignment involves a predetermined fixed percentage of the assignor's net revenue interest being transferred to the assignee. The assigned interest remains constant regardless of changes in the overall net revenue. 2. Floating Percentage Assignment: In this type, the assigned percentage fluctuates based on the assignor's net revenue interest. As the net revenue changes, the assignee receives a proportionate share of the remaining net profits. 3. Cost-Based Assignment: This assignment method deducts specific costs from the assignor's net revenue interest before calculating the assigned overriding royalty interest. These costs may include production costs, operating expenses, and other relevant expenditures. 4. Absolute Net Profits Assignment: In this type of assignment, the overriding royalty interest is calculated based on the absolute net profits generated. After deducting all costs, the assignee receives a percentage of the remaining net profits. These various types of Alaska Assignment of Overriding Royalty Interests provide flexibility for assignors and assignees to negotiate their terms, making the agreements adaptable to specific financial circumstances and oil and gas production conditions. By leveraging these assignments, assignees can participate in the revenue stream of oil and gas projects while sharing in the net profits after accounting for various deductions.
