You've got it Ben - Take your 3 months of data and multiply by 4 to extrapolate a year of costs. It's not a perfect solution but its the best you can do (and its what the GBCI expects).

Can I also have my performance period from January to April 2011 and multiply it with 3 even if the year 2011 is not ended?

I understand most credits have a minimum 3 month long performance period, but EA Prereq 2 has a minimum of 12 months. So for the purpose of this credit, would we not include 12 months of information for the performance period building expenses?

Hi Michelle The trick with performance periods is that all credits (except EAp2) must have a MINIMUM performance period of 3 months and a MAXIMUM of 24 months, they all just have to end within 30 days of each other. So for this credit, you can submit 3 months - 24 months of performance period data, but you will have to extrapolate the data if the performance period is less than 12 months. Hope this helps Hannah
