|A statement, that is qualitative and/or quantitative, on the
results of a single asset or a single building when compared to others
in the same class.
1. In reference to an asset, an asset that achieves a service life that is less than the modal year on the probability distribution when compared to all other assets of the same class (equal life group).
2. In reference to a building, the reinvestment funding requirements are higher than the average of all the buildings in the statistical population as a result of factors such as less durable products, high exposure conditions and poor maintenance practices.
Listed below are some of the attributes of "poor" performer asset scenarios:
Included below are some examples of "poor" performer scenarios relative to asset performance
Listed below are some of the reasons why an asset will exhibit poor performer characteristics:
Understanding of high performers requires analysis relative to the following statistical concepts
Included below are some of the asset management principles to be considered in relation to high performer assets.

a right-modal survivor curve.
