186. For each subsequent year, the qualification for a personalized rate, as well as the first- and second-level risk indices of a successor referred to in section 185, are determined as follows:(1) by determining, with respect to each predecessor and in accordance with Chapter II, the successor’s qualification for a personalized rate, as well as, where applicable, the first- and second-level risk indices using, for any period prior to the date on which the transaction took place and which falls within the first- and second-level reference periods, the predecessor’s actual and expected experience. If the successor does not qualify for one year following any such determination, the successor’s first- and second-level risk indices corresponding to that determination are equal to 1;
(2) if, for the subsequent year, the successor qualifies for a personalized rate in respect of at least one of the determinations made under paragraph 1, by determining, in accordance with Subdivision 2, the weighted average of the first-level risk indices determined under that paragraph, and the weighted average, determined in accordance with the same Subdivision, of the second-level risk indices determined under that paragraph.
