Segment Reporting [Abstract] |
Segment Reporting, Policy | We have two strategic business units that we manage separately—Mortgage Insurance and Services. Adjusted pretax operating income (loss) for each segment represents segment results on a standalone basis; therefore, inter-segment eliminations and reclassifications required for consolidated GAAP presentation have not been reflected. Inter-segment activities are recorded at market rates for segment reporting and eliminated in consolidation. We allocate to our Mortgage Insurance segment: (i) corporate expenses based on the segment’s forecasted annual percentage of total revenue, which approximates the estimated percentage of time spent on the segment; (ii) except as described below for periods prior to January 1, 2019, all interest expense; and (iii) all net investment income from corporate cash and investments. Prior to January 1, 2019, interest expense related to the Clayton Intercompany Note was allocated to our Services segment. Effective January 1, 2019, Radian Group recapitalized the Services segment with a capital contribution that enabled the Services segment to repay the Clayton Intercompany Note and its accumulated allocated interest expense associated with the note, and effective as of the same date, all interest expense is allocated to our Mortgage Insurance segment. We allocate to our Services segment: (i) corporate expenses based on the segment’s forecasted annual percentage of total revenue, which approximates the estimated percentage of time spent on the segment and (ii) until January 1, 2019, the allocated interest expense related to the Clayton Intercompany Note as discussed above.
