For Alberta CPI, 2009 and 2010 values are as forecasted by Conference Board of Canada
The highlighted index values are determined by multiplying the last index value by the simple average of Year On Year % increase in
index values in preceding five years
To derive the Composite Index, all indices were weighted by total of the actual project cost associated with them
