[1] Outstanding RSUs represent shares that have not yet been issued because not all conditions necessary to earn the right to benefit from the instruments have been satisfied. For performance-based awards, the final number of RSUs distributed depends on: (i) the cumulative growth in Radian’s book value per share adjusted for certain defined items over the respective three-year performance period and, for the performance-based RSUs granted starting in 2023, a modifier based on a comparison of our total shareholder return to the total shareholder return of certain of our peers and (ii) with the exception of certain retirement-eligible employees, continued service through the vesting date, which could result in changes to the number of vested RSUs.
[2] For performance-based RSUs, amount represents the number of target shares at grant date
[3] For performance-based RSUs, amount represents the difference between the number of shares vested at settlement, which can range from 0 to 200% of target depending on results over the applicable performance periods and the number of target shares at the grant date.
[4] Represents amounts vested during the period, including the impact of performance adjustments for performance-based awards.
[5] Includes 176 thousand performance-based shares and 116 thousand time-vested shares granted to employees in our Mortgage Conduit, Title and Real Estate businesses, which are presented as discontinued operations.
