On or before the third Friday in September the assessor shall compute the contribution to be made based on the determined valuation using the method of assessment applied in assessing ad valorem taxes of properties of similar character and devoted to the same use in the county for the current tax year.

3. 3. The assessor shall:

   1. (a) Submit the computation of the contribution to the board of supervisors at the same time that the assessor submits the assessment roll.
   2. (b) Notify the county school superintendent of the amount of the contribution.
