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 2010.
