(2) The assessor shall multiply the certified constitutional reduction percentage by the pre-reduction Measure 50 tax amount determined under ORS 310.216 and then add to the product any of the following taxes applicable to the district:
(a) If the taxing district is other than a city, county or school district, taxes imposed to support a hospital facility; and
(b) Taxes imposed pursuant to an operating tax levy approved by voters prior to December 5, 1996, for which property taxes are first imposed for the tax year beginning July 1, 1996, or July 1, 1997, if the levy was approved by voters in an election:
(A) In which at least 50 percent of registered voters eligible to vote in the election cast a ballot; or
(B) That was the general election in an even-numbered year.
(3) The assessor shall then calculate the operating tax rate for the district by dividing the amount determined under subsection (2) of this section by the assessed value of taxable property in the district determined under ORS 310.232. The rate so determined shall be the district’s permanent rate limit for operating taxes.
(4)(a) If the taxing district is a district for which a supplemental statutory reduction percentage has been certified to the assessor, the assessor shall repeat the calculation described in subsection (2) of this section, substituting the total reduction percentage for the constitutional reduction percentage. Any district taxes that are described in subsection (2)(b) of this section shall be reduced by the supplemental reduction percentage in determining the amount.
(b) The assessor shall then calculate the operating tax rate for the district by dividing the amount determined under paragraph (a) of this subsection by the assessed value of taxable property in the district determined under ORS 310.232. The rate so determined shall be the district’s statutory rate limit for operating taxes.
(5) If, in the written notice made under ORS 310.206, the district made a separate certification for permanent rate limit purposes and for 1997 operating tax purposes, and the rate determined under subsection (3) of this section, or subsection (4) of this section (if applicable), will produce operating taxes greater than the amount certified for operating taxes, the rate determined under subsection (3) or (4) of this section shall be adjusted so as to produce the amount certified by the district. Except as provided in ORS 310.234, the adjusted rate shall not be used for any purpose under ORS 310.200 to 310.242 other than determination of the district’s ad valorem property taxes for the tax year beginning July 1, 1997.
(6) The assessor shall determine a rate per $1,000 of assessed value for any of the following taxes applicable to the district:
(a) Taxes imposed to pay qualified obligations of the district;
(b) Local option taxes; and
(c) Taxes imposed to pay exempt bonded indebtedness.
(7) The rates per $1,000 of assessed value determined under subsection (6) of this section shall be determined by dividing the amount of the tax for which a rate is being determined by the assessed value of taxable property in the district under ORS 310.232.
(8) The assessor shall determine a total rate for the district and a rate for each category described in ORS 310.150 for the district.
(9) Based on the rates determined under subsection (8) of this section, the assessor shall determine a pre-compression consolidated rate for each code area and a pre-compression consolidated rate per category described in ORS 310.150 for each code area. [1997 c.541 §32]
