Non-underwriting Disclosures. The Company provides additional disclosures for corporate and other (non-operating) income and expenses. Corporate and other income and expenses include: corporate expenses, non-operating expenses, net investment income, net realized and unrealized investment gains or losses, changes in fair value of derivatives, interest expenses, net realized and unrealized foreign exchange gains or losses, and income taxes. These income and expense items are not allocated to the Company’s business segments as they are not directly related to the Company’s business segment operations and is consistent with how the CODM measures the performance of the business segments. The Company does not allocate its assets by business segment as we evaluate underwriting results of each segment separately from the results of our investment portfolio.

The Company uses underwriting ratios as measures of performance. The loss ratio is the ratio of losses and loss adjustment expenses to net earned premiums. The acquisition cost ratio is the ratio of acquisition costs to net earned premiums. The general and administrative expense ratio is the ratio of general and administrative expenses to net earned premiums. The combined ratio is the sum of the loss ratio, the acquisition cost ratio and the general and administrative expense ratio.
