(1) The wholesale market value of heavy equipment shall be the quick sale as shown in the "Green Guide" and "Green Guide for Older Equipment" for the current year of assessment. This guide may be reviewed in the department or purchased from the publisher and is incorporated by reference: Dataquest, 1290 Ridder Park Drive, San Jose, California 95131.

(2) For all heavy equipment which cannot be valued under (1) , the department shall try to ascertain the original FOB through old heavy equipment valuation guidebooks. If an original FOB cannot be ascertained, the department may use trending to determine the FOB. The FOB or "trended" FOB will be used in conjunction with the depreciation schedule in (5) to arrive at a value which approximates wholesale value. The trend factors are the most recent available in the Marshall Valuation Service Manual for the year of assessment. The Marshall Valuation Service Manual published by Marshall and Swift Publication Company, 915 Wilshire Boulevard, 8th Floor, P.O. Box 26307, Los Angeles, California 90026-0307, is adopted by reference.

(3) For equipment that cannot be valued under (1) and (2) , the value for heavy equipment shall be ascertained by trending the quick sale as found in the guide in (1) , for the same make and model. The trend factors are the same as those mentioned in (2) .

(4) The wholesale market value of heavy equipment that cannot be valued under (1) , (2) , or (3) shall be the acquired cost, as certified by the owner or applicant to the department as applied to the depreciation schedule in (5) . The department may require proof from the taxpayer to certify the accuracy of the acquired cost.

(5) The trended depreciation schedule referred to in (2) , (3) , and (4) is listed below and shall be used for tax year 2007. The values derived through the use of these percentages approximate the "quick sale" values as calculated in the guidebooks listed in (1) .
