§  1262.  Manner  by  which ratios shall be determined. In determining  ratios pursuant to this article, the state board  shall,  for  the  last  completed  assessment  rolls  and  the  four preceding assessment rolls,  determine the ratios of assessed valuation to full valuation as  of  the  first  day  of  January  of  the  fiscal  year  for which the ratios are  applicable. Each ratio shall be determined on the basis  of  the  market  value  survey  completed  pursuant to article twelve of this chapter and  for which the valuation date  is  the  first  day  of  January  of  each  applicable  year.  In  the event that a market value survey has not been  completed based upon each such valuation date,  the  state  board  shall  determine the ratios in the following manner:    (a)  compute the ratios of assessed valuation to the full valuation of  taxable real estate on the  basis  of  market  value  surveys  completed  pursuant to article twelve of this chapter;    (b) on the basis of the ratios computed pursuant to subdivision (a) of  this section, project increases or decreases in the ratios for years for  which  the information has not been developed pursuant to article twelve  of this chapter;    (c) avail itself of appropriate market value information appearing  in  its  office  or acquired in the discharge of its duties pursuant to this  chapter.
