For the purposes of this section, the base percentage and the\ncurrent percentage of each class and for each portion shall be computed\npursuant to this subdivision.\n  (a) Base percentage. The base percentage for each class for each\nassessing unit and portion thereof shall be determined as follows:\n  (1) Determine the estimated market value of each class by dividing the\ntaxable assessed value of the real property in each class in the special\nassessing unit and portion thereof appearing on the final assessment\nroll completed and filed in nineteen hundred eighty-nine by the class\nequalization rate which was finally adopted by the commissioner for such\nroll.\n  (2) Adjust the estimated market value of each class to reflect any\nchange in the class designation of any parcel of real property.\n  (3) Determine the total estimated market value of the special\nassessing unit or portion thereof by summing the estimated market value\nof each class.\n  (4) Divide the estimated market value for each class by the total\nestimated market value of the special assessing unit or portion thereof.\n  Such quotient, as expressed as a percentage to at least four places to\nthe right of the decimal point, shall be the base percentage of each\nclass for such special assessing unit or portion thereof.\n  (b) Current percentage. The current percentage for each class for each\nassessing unit and portion thereof shall be determined as follows:\n  (1) Determine the estimated market value of each class by dividing the\ntaxable assessed value of the real property in each class in the special\nassessing unit and portion thereof appearing on the latest final\nassessment roll for which class equalization rates have been finally\nadopted by the commissioner by the class equalization rate which was\nfinally adopted by the commissioner.\n  (2) Determine the total estimated market value of the special\nassessing unit or portion thereof by summing the estimated market value\nof each class.\n  (3) Divide the estimated market value for each class by the total\nestimated market value of the special assessing unit or portion thereof.\n  Such quotient, as expressed as a percentage to at least four places to\nthe right of the decimal point, shall be the current percentage of each\nclass for such special assessing unit or portion thereof.\n  3. Where there was no taxable real property in a class in a portion on\nthe final assessment roll completed and filed in nineteen hundred\neighty-nine, the local base proportion, base percentages and current\npercentages for such portion shall be determined as provided by this\nsubdivision for each tax levy based upon an assessment roll filed\nsubsequent to the assessment roll on which such property first appears.\n  (a) The local base proportions shall be the adjusted proportions or\nadjusted base proportions, whichever are appropriate, determined\npursuant to this section for the assessment roll on which such property\nfirst appears.\n  (b) The base percentage for each class shall be determined as follows:\n  (1) For each class other than the class appearing for the first time,\ndetermine the estimated market value by dividing the taxable assessed\nvalue of the real property in the class in the portion on the final\nassessment roll on which the new class first appeared by the class\nequalization rate determined for such class in such portion on such\nroll.\n  (2) For the class appearing for the first time, determine the\nestimated market value of such class by dividing the taxable assessed\nvalue of the real property in such class on the final assessment roll on\nwhich such class first appeared by the class equalization rate\ndetermined for such class in the special assessing unit on such final\nassessment roll.\n  (3) Determine the total estimated market value of the portion by\nsumming the estimated market value of each class.\n  (4) Divide the estimated market value for each class by the total\nestimated market value of the portion. Such quotient, as expressed as a\npercentage to at least four places to the right of the decimal point,\nshall be the base percentage of each class for such portion.\n  (c) Current percentages shall be determined as otherwise provided by\nthis section, except that until the commissioner can determine a class\nequalization rate for the new class in such portion, the class\nequalization rate for the class in the special assessing unit shall be\nused in lieu thereof.\n  4. Where there is a new portion that did not appear on the final\nassessment roll completed and filed in nineteen hundred eighty-nine, the\nlocal base proportion, base percentages and current percentages for each\nclass in such portion shall be determined as provided in subdivision\nthree of this section for a new class in a portion.\n  5. Adjusted base proportions. No later than five days subsequent to\nthe filing of the final assessment roll, the legislative body of each\nspecial assessing unit shall adjust such current base proportions to\nreflect the addition to the assessment roll of new property, additions\nto or improvements of existing property or formerly exempt property or\nthe full or partial removal from the assessment roll of property by\nreason of fire, demolition, destruction or new exemption or any change\nin the class designation of any parcel of real property subsequent to\nthe taxable status date of the latest final assessment roll for which\nclass equalization rates have been finally adopted. The current base\nproportions so adjusted shall be known as the adjusted base proportions.\n  6. Upon determination of the adjusted base proportions, the\nlegislative body of the special assessing unit shall certify within five\ndays to the commissioner, on forms prescribed by the commissioner, the\nadjusted base proportions as computed pursuant to subdivision five of\nthis section for each class applicable to the special assessing unit and\neach portion contained therein; the assessed value of all property in\neach class for the special assessing unit and each portion contained\ntherein; the net change in assessed value for each class on the\nassessment roll resulting from the additions to or removals from the\nassessment roll referred to in subdivision five of this section for the\nspecial assessing unit and each portion contained therein; and the net\nchange in assessed value for each class on the assessment roll resulting\nfrom changes other than those referred to in subdivision five of this\nsection for the special assessing unit and each portion therein.\n  7. If subsequent to and within sixty days after the certification of\nthe adjusted base proportions as final by the legislative body of the\nspecial assessing unit, should said legislative body discover that a\nmathematical error was made in the determination of the adjusted base\nproportions, the legislative body of the special assessing unit which\nhas made such error shall redetermine such adjusted base proportions,\nsubject to the procedures set forth in this section for the review and\ncertification of adjusted base proportions, prior to the levy of taxes\nfor that fiscal year. If the redetermination cannot be made prior to the\nextension of taxes for that fiscal year, the tax levying body shall\nadjust the tax levy for the ensuing fiscal year to account for the\nimproper apportionment of taxes which resulted from the error in the\ndetermination of the adjusted base proportions.\n  8. Notwithstanding any other provision of this article, the\ncalculations required by this section shall not apply to town or county\nspecial districts or zones of assessment.\n
