(1) As we evaluate the underwriting results of each of our reportable segments separately from the results of our investment portfolio, we do not allocate net investment income to our reportable segments.
(2) General and administrative expenses incurred by our reportable segments are allocated directly. Certain corporate overhead is allocated to our reportable segments based on estimated consumption, headcount and other variables deemed relevant to the allocation of such expenses. Other corporate expenses do not relate to underwriting operations and, therefore, are not allocated to our reportable segments.
