Segment Reporting [Abstract]  
Schedule of Segment Information
The following table reconciles the components of reportable segment profit and loss to consolidated profit and loss for the periods presented. Within the tables, we have disclosed significant segment expenses at a level of disaggregation that coincides with what is regularly provided to the CODM. Other underwriting and operating expenses in the Mortgage Insurance and Reinsurance segments include software, professional fees, travel, and occupancy costs. The accounting policies of our operating segments are the same as those described in the summary of significant accounting policies in our Form 10-K. We do not have inter-segment transactions.
