Oregon Revised Statutes Revenue and Taxation § 311.860

(a) The payment of moneys to the taxing unit by the person proposing to construct the facility. The person shall make the payment prior to or during the period of the construction.

(b) The amounts of the payments to be made by the person proposing to construct the facility and the dates for making the payments.

(c) A reduction in real market value for the facility for purposes of computing the rate of levy of the taxing unit entering into the agreement for each year of a period of years, not to exceed 10, commencing on or in the course of completion of the construction of the facility. The amount of reduction allowed by the agreement shall be a percentage amount, not to exceed 50 percent, of the real market value of the facility as of any assessment date affected by the reduction, and may be fixed or graduated over the period of years for which the reduction is allowed. The total reduction allowed by the agreement shall result in a tax benefit for the facility that is estimated to be equivalent to the total amount of payments made under the agreement to the taxing unit, plus interest at the maximum rate of eight percent per annum from the date of each payment. In no event, however, shall the total reduction in real market value during the period of years of reduction cause a total reduction in taxes that exceeds the total amount of moneys previously paid plus interest.
