I joined AIChE within the last few months. Why did I get a dues invoice?
Membership dues are pro-rated. If you joined in June, 2004 and your dues were $199, $99.50 would go towards membership for the current year and $99.50 would go towards next year’s membership. If your dues were $199 for 2005 and $99.50 has already been put towards those dues, there would be a remaining balance of $99.50. This amount is appropriated dependent on the time of year membership is activated.
