(a) For a new or acquiring district that has reorganized pursuant to paragraph (1), (2), or (3) of subdivision (a) of Section 35511 or subdivision (b) of Section 35511, the funding amount per unit of average daily attendance pursuant to subparagraph (A) of paragraph (1) of subdivision (a) of Section 42238.03 shall be calculated, as follows: (1) If the reorganization took place before December 31, 2013, for each affected district: (A) Blend the revenue limit pursuant to Section 35735.1, as that section read on January 1, 2013. (B) Multiply the average daily attendance for the fiscal year two years before the fiscal year in which the reorganization is to become effective by the per unit of average daily attendance amount computed pursuant to subparagraph (A) of paragraph (1) of subdivision (a) of Section 42238.03. (C) Add the products determined in subparagraph (B) and divide by the sum of units of average daily attendance for the fiscal year two years before the fiscal year in which the reorganization is to become effective for all affected districts. (2) If the reorganization took place after December 31, 2013, for each affected district: (A) Multiply the average daily attendance for the fiscal year immediately preceding the fiscal year in which the reorganization is to become effective by the per unit of average daily attendance amount computed pursuant to subparagraph (A) of paragraph (1) of subdivision (a) of Section 42238.03. (B) Add the products determined in subparagraph (A) and divide by the sum of units of average daily attendance for the fiscal year immediately preceding the fiscal year in which the reorganization is to become effective for all affected districts. (3) (A) For purposes of paragraphs (1) and (2), average daily attendance shall be the funded average daily attendance as of the second principal apportionment. (B) If the reorganization includes a divided district, the following shall apply: (i) For purposes of paragraph (1), the average daily attendance shall be estimated by the county office of education and reported to the department based on the units of average daily attendance to be served by the reorganized district. (ii) For purposes of paragraph (2), the average daily attendance shall be estimated by the county office of education and reported to the department based on the units of average daily attendance to be served by the reorganized district in the first fiscal year the reorganization becomes effective. If no average daily attendance of the divided district is estimated to be served in the first fiscal year of the reorganization, the divided district’s funding shall not be included in the blending calculation made pursuant to subparagraph (A) of paragraph (1) of subdivision (a) of Section 42238.03. (C) For purposes of paragraph (1) or (2), if the reorganization includes a former district that has been wholly included in more than one new or acquiring district, the average daily attendance shall be the average daily attendance reported pursuant to subdivision (c) of Section 35735. (b) For a new district formed as a result of deunification pursuant to paragraph (4) of subdivision (a) of Section 35511, the funding amount per unit of average daily attendance pursuant to subparagraph (A) of paragraph (1) of subdivision (a) of Section 42238.03 shall be equal to the amount calculated for the original district for the fiscal year before the fiscal year in which the reorganization is to become effective.
