Explanation of Responses:

( 1 )Included in the total are 10,727 restricted stock units awarded on February 21, 2018 pursuant to the Assured Guaranty Ltd. 2004 Long-Term Incentive Plan (the "Plan"). These restricted stock units vest on the third anniversary of the date of the award. Upon vesting, one (1) common share will be delivered for each vested restricted stock unit. ( 2 )Included in the total are 7,481 restricted stock units awarded on February 27, 2019 pursuant to the Plan. These restricted stock units vest on the third anniversary of the date of the award. Upon vesting, one (1) common share will be delivered for each vested restricted stock unit. ( 3 )Included in the total are 6,334 restricted stock units awarded on February 26, 2020 pursuant to the Plan. These restricted stock units vest on the third anniversary of the date of the award. Upon vesting, one (1) common share will be delivered for each vested restricted stock unit. ( 4 )These securities are held in a trust for the benefit of the reporting person's children and for which the reporting person's spouse serves as a trustee. The reporting person disclaims beneficial ownership of these securities, and this report shall not be deemed an admission that the reporting person is the beneficial owner of the securities for purposes of Section 16 or for any other purpose. ( 5 )Performance share units awarded pursuant to the Plan. Each performance share unit represents a contingent right to receive one (1) common share of the Company. With limited exceptions, the performance share units vest on 2/21/2021, if at all, at the end of the performance period (7/1/2019 to 12/31/2020), assuming that the holder remains employed at such time, based on the Company's common share price using the highest 40-day average stock price during the performance period as follows: 200% if the share price reaches $50; 100% if the share price reaches $46; and 50% if the share price reaches $42 (with interpolation between those prices). If the share price does not reach $42, none of the performance share units will vest. ( 6 )To the extent unvested performance share units do not become vested units at the end of the applicable performance period as described above, such unvested performance share units will expire at the end of such performance period. Upon vesting, one (1) common share will be delivered for each vested performance share unit.
