Remarks: 

【Judgment criteria exceptions】
For manufacturers, etc. , if a category falls below its energy efficiency standard but the weighted harmonic mean of each model's energy efficiency (APF) and the number of models shipped (mean APF by company) does not fall below the weighted harmonic mean of the energy efficiency standard and that same number (standard energy efficiency by company),the categories that did not fall below that value will be deemed as achieving the standard.
However, target fiscal year vary by category: In FY2027 and FY2028 will calculate only categories I through IV.
