What is the value of MDU’s property, used and useful, for the service and convenience of the public in North Dakota? 2. What is MDU’s rate of return on its property, used and useful, for the service and convenience of the public in North Dakota? 3. What is a just and reasonable rate of return on MDU’s property, used and useful, for the service and convenience of the public in North Dakota? 4. What rates and charges are necessary to provide a just and reasonable rate of return on MDU’s property, used and useful, for the service and convenience of the public in North Dakota? 5. Are MDU’s rate schedules designed in such a manner that they result in a basis of charge to its customers that is just and reasonable without discrimination?
