WAC 458-53-160 — Indicated Personal Property Ratio—Computation
Agency filings affecting this section (1) Determination of ratio for assessed value strata. For each personal property assessed value stratum, excluding properties identified in WAC 458-53-070 (4)(a), an average assessed value, and an average market value shall be determined from the results of selected audit studies. The average assessed value for each stratum divided by the average market value determines the ratio for each assessed value stratum. (2) Determination of indicated market value. The actual total assessed value of the county for each stratum divided by the ratio for each assessed value stratum, as determined by using the calculation set forth in subsection (1) of this section, determines the indicated market value of each stratum for the county. (3) Additional categories. The actual county total assessed values of properties identified in WAC 458-53-070 (4)(a) are added as a separate category to the total county assessed value. A ratio determined for these properties is applied against the total assessed value for the category to determine the indicated total market value for the category. (4) Determination of county indicated ratio. The sum of the actual total county assessed values is divided by the sum of the indicated market values to determine the county indicated personal property ratio. (5) Example. The following illustration, using simulated values and ratios, indicates the ratio computation procedures for personal property.
