EHFs were determined by OPEIC based on industry-best practices and other factors including:

• Total product weight per category
• Costs of program administration
• Product sales and forecasts

The program is designed so the cost of managing one category is not subsidized by the EHFs paid by another category. EHFs will be reviewed periodically and will be re-adjusted if necessary.

On October 1, 2016, the EHF's were adjusted downward to better reflect the administrative costs of managing the OPEIC program.
