Oregon Administrative Rules
Chapter 150 - DEPARTMENT OF REVENUE
Division 314 - INCOME TAXATION GENERALLY GENERAL PROVISIONS
Section 150-314-0406 - Property Factor; Averaging Property Value

(1) As a general rule the average value of property owned by the taxpayer shall be determined by averaging the values at the beginning and ending of the tax period. However, the Department may require or allow averaging by monthly values if such method of averaging is required to properly reflect the average value of the taxpayer's property for the tax period. Averaging by monthly values will generally be applied if substantial fluctuations in the values of the property exist during the tax period or where property is acquired after the beginning of the tax period or disposed of before the end of the tax period.

Example: The monthly value of the taxpayer's property was as follows: [Example not included. See ED. NOTE.]

(2) Averaging with respect to rented property is achieved automatically by the method of determining the net annual rental rate of such property as set forth in OAR 150-314-0400.
