Yao,
Currently I am in Spokane, but when I return I would be happy to show you how the conversion factor works, where it
comes from, why there are 2 different factors in the case, as well as an explanation of why we use a conversion factor
and how it is calculated.
I know that all the accounting terminology and schedules can be intimidating and I would be happy to explain how and
why this accounting deferral mechanism came into being, including the small forecast piece as well as the rate design.
I have worked on Avista's and Idaho Power's PCA filings for many years now, and my offer still stands to go over the
filing with you when I get back to Boise next week. I am probably one of the most knowledgeable people at the !PUC in
regards to the power cost adjustment mechanisms for Avista and Idaho Power, and would be happy to help you with this
current filing.
Kathy

Good morning! Kathy and Mike had asked about this last week, so I discussed Monday morning with Kathy. The
conversion factor is approved in the General Rate Case and the .99422 is based on Order number 33437. I have
attached it for your records.
Thank you!

Hi Annette,
Could you please let us know how Avista calculated the conversion factor (0.994222) used in the PCA case?
Thanks a lot.
