Segment Reporting [Abstract] |
Segment Reporting | Segment Reporting We operate our business in a single reportable segment, Mortgage Insurance, which is how our CODM, who is our Chief Executive Officer, reviews our financial performance and allocates resources. We derive revenue primarily through writing and assuming residential mortgage guaranty insurance in the United States. We manage our single segment on a consolidated basis, and our reported measure of segment profit or loss is consolidated net income. The CODM uses net income to evaluate income generated from segment assets in deciding how to reinvest profits into the core business, or into other parts of the entity, such as new business initiatives or to return capital to shareholders. Net income is also considered in our competitive analysis and financial planning processes. Our significant segment expenses are those disclosed on our condensed consolidated statements of income and our measure of segment assets are those reported on the condensed consolidated balance sheets.
