Portfolio level metrics represent intensities of the portfolio as they were during the given reporting period. As such, comparing annual intensities at a portfolio level doesn’t represent a direct like-for-like comparison as assets will have changed between reporting years due to acquisitions and divestments.
 
Asset level intensities have only been provided for assets included in Investa's portfolios in the current reporting period. As such, recalculations of portfolio level intensities for prior reporting periods using the provided asset level intensities will not align.
