ARM 42.21.140. OIL DRILLING RIGS

(1) Bids for new rigs will be solicited from manufacturers of oil drilling rigs to determine current replacement costs based on the depth rating listed below. For each depth rating listed below for oil drilling rigs, there will be two replacement cost categories. One category will represent current replacement cost of a mechanical rig and the second category will represent current replacement cost of an electric rig. Each rig as it is assessed will be placed in a value category based on its depth. (2) The department shall prepare a ten-year trended depreciation schedule for oil drilling rigs. The trended depreciation schedule shall be derived from depreciation factors published in the Marshall & Swift Valuation Service Guide. The "% good" for all drill rigs less than one year old shall be 100 percent. The trended depreciation schedule for tax year 2018 is listed below. YEAR NEW/ ACQUIRED % GOOD TREND FACTOR TRENDED % GOOD 2018 100% 1.000 100% 2017 92% 1.000 92% 2016 84% 1.011 85% 2015 76% 1.001 76% 2014 67% 1.009 68% 2013 58% 1.021 59% 2012 49% 1.023 50% 2011 39% 1.050 41% 2010 30% 1.079 32% 2009 24% 1.064 26% 2008 and older 21% 1.101 23% (3) In any year that the information required in (1) is not available for use by the department, oil drilling rigs shall be valued by using the previous year's schedule. (4) This rule is effective for tax years beginning after December 31, 2017.
