42.21.155    CATEGORIES FOR PERSONAL PROPERTY; TRENDED DEPRECIATION SCHEDULES; TREND FACTOR CALCULATION

(1) The department has established eight categories of personal property for determination of trend factors and depreciation, and trended depreciation schedules of four, five, ten, fifteen, or twenty years have been assigned for each category based on its type and expected useful lifespan, as provided in (4). The equipment listings in (4) provide representative examples of property in a category and are not meant to be an exhaustive list. 

(2) Each trended depreciation schedule contains a residual trended percent good, designated as "older" in the final row of each schedule, which is applied to an item of personal property that exceeds the typical lifespan because personal property remains taxable until its disposal. The purpose of trended depreciation is to bring the cost of equipment acquired in a previous year to an approximate current cost before depreciating it.

(3) Prior to January 1 of each year, the department will use cost index trends for equipment and depreciation percentages for furniture and fixtures from the previous July's edition of Marshall & Swift Valuation Service Guide (Marshall & Swift Guide) to calculate the trend factors and the trended percent good for the schedules in (4). The Marshall & Swift Guide is a widely recognized valuation authority which the department adopts and incorporates by reference. The Marshall & Swift Guide may be reviewed at the department's central office or purchased from the publisher: Corelogic, 777 South Figueroa, 12th Floor, Los Angeles, California 90026-0307.

(a) The trends from the Marshall & Swift Guide represent industry-wide national average changes in equipment costs - customarily increases - from the base year, 1926. Trends are typically greater than a value of one, but may be less than one.

(b) For trended depreciation schedules, the department calculates the year one trend for each schedule as the average trend of the first three quarters of the current year. The trend for each successive year is the final trend for that year.

(i) Using year one as the base year, the department calculates the changes in equipment costs - the trend factors - for each schedule in (4), as the quotient of the year one trend and any following year's trend.

(ii) The department then uses the depreciation percentages from the Marshall & Swift Guide to calculate the "percent good" over the period of years that is typical for each property category. Trended percent good is then calculated as the product of the percent good and the trend factor for each year represented in a schedule.

(4) The trended depreciation schedules for the categories of personal property are as follows:

(a) Computerized Equipment - a four-year depreciation and a residual percentage will be applied to computerized equipment such as computers, peripheral equipment that cannot function independently of a computer, computerized medical equipment, and gaming machines. The four-year depreciation schedule was developed and implemented after consultation with industry representatives; the trend factors are calculated from the office equipment category of the Marshall & Swift Guide.
