Movable equipment - apportionment of value

(1) Any person owning any portable or movable equipment which is apt to be located or maintained in two or more counties of the state during any calendar year shall indicate in a statement accompanying his personal property schedule the kind and description and a serial number, if available, of such equipment, the counties in which such equipment is apt to be located or maintained, and the estimated period of time during the calendar year in which such equipment is apt to be so located and maintained.

(2) The assessor of the county in which such equipment is located on the assessment date shall determine its value and shall apportion such value between the counties affected and the school districts thereof, in the proportion that the periods of time during which such equipment may be located or maintained in such counties bear to the full calendar year. He shall furnish a copy of such valuation and apportionment to the owner of such equipment or to his agent and shall also transmit a copy thereof to the assessor of each county affected as his authority to list the apportioned value of such equipment on the assessment roll of his county. For purposes of making such apportionment, the valuation of the portable or movable equipment made by the assessor of the county of original assessment shall be used by all county assessors involved.

(3) If, subsequent to the making of such apportionment of value, any such equipment is removed to a county not initially included in such apportionment or if any such equipment is located or maintained in any county for a period of time different from that used in the initial apportionment, then an amended apportionment of value shall be requested by the assessor of any county so affected. Such assessor shall furnish a copy of such requested amended apportionment to the owner of such equipment or to his agent and shall also transmit a copy thereof to the assessor of each county affected, as his authority to list such reapportioned value on the assessment roll of his county. Failure of a county assessor to request such an amended apportionment shall permit the original apportionment of value to stand, and no other county assessor shall assess such equipment as is listed in the original apportionment for any period during the year of the original assessment. If such amended apportionment of value is received by any assessor after he has filed his annual abstract of assessment with the administrator, then either an abatement or an additional assessment shall be made, as the case may be.

(4) Repealed.
