| | (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) | Amounts related to our reportable segments reflect underwriting-related general and administrative expenses, including those incurred directly by segment personnel and certain corporate overhead costs allocated based on estimated consumption, headcount and other variables deemed relevant. Other corporate overhead costs, which are are not incremental and/or directly attributable to our individual underwriting operations, are not allocated to our reportable segments and are presented separately as corporate expenses. |
