For our goodwill impairment analysis, we allocate all of the goodwill to the individual operating segments. We identify reporting units that are one level below an operating segment (referred to as a component), and distinguish these reporting units based on how the segments and components are managed, taking into consideration the economic characteristics, nature of the products and customers of the components. We allocate goodwill to reporting units based on relative fair value, using certain performance metrics. See Note 18 for further information on management reporting.

The following table shows the allocation of goodwill to our operating segments for purposes of goodwill impairment testing.
