______________ | | (1) | Services revenue for the first quarter includes $101 thousand that had previously been included in other income. |
| | (2) | The 2015 and 2014 amounts reflect primarily unrealized (losses) gains, respectively, on our trading securities. |
| | (3) | Radian completed the sale of Radian Asset Assurance to Assured on April 1, 2015, pursuant to the Radian Asset Assurance Stock Purchase Agreement dated as of December 22, 2014. Until the April 1, 2015 sale date, the operating results of Radian Asset Assurance were classified as discontinued operations for all periods presented in our consolidated statements of operations. See Note 3 for additional information. |
| | (4) | Diluted net income per share and average shares outstanding per the accounting standard regarding earnings per share. |
| | (5) | Diluted net income per share is computed independently for each period presented. Consequently, the sum of the quarters may not equal the total net income per share for the year. For all calculations, the determination of whether potential common shares are dilutive or anti-dilutive is based on net income from continuing operations. |
| | (6) | This amount reflects a reversal of substantially all of our tax valuation allowance in the fourth quarter of 2014. |
| | (7) | Reflects a $468 million loss on reclassification of Radian Asset Assurance as assets held for sale in the fourth quarter of 2014. |
