ARM 42.21.139. WORK-OVER AND SERVICE RIGS

(1) Bids for new rigs will be solicited from manufacturers of work-over and service rigs to determine current replacement costs based on the depth rating listed below. For each depth rating listed below of work-over and service rigs, there will be two replacement cost categories. One category will represent current replacement cost of a service rig and the second category will represent current replacement cost of a work-over rig. Each rig, as it is assessed, will be placed in one category or another based on its depth. (2) The department shall prepare a ten-year trended depreciation schedule for work-over and service rigs. The trended depreciation schedule shall be derived from depreciation factors published by "Marshall and Swift Publication Company". The "% good" for work-over and service rigs less than one year old shall be 100%. (3) In any year that the information required in (1) is not available for use by the department, work-over and service rigs shall be valued by using the schedule from the previous year. (4) For self-propelled wheeled work-over and service rigs, an additional 80% wholesale factor shall be used in determining market value in conjunction with the schedules mentioned in (2) . (5) The trended depreciation schedule referred to in (2) and (4) is listed below and shall be used for tax year 2007.
