    <remarks>On July 27, 2020, CoreLogic, Inc. (the &quot;Company&quot;) filed a Form 10-Q with the Securities and Exchange Commission, indicating that the Company had increased its shares of common stock outstanding to 79,458,522 shares, as of July 21, 2020, thereby reducing the Reporting Persons' beneficial ownership position to 9.99%. Therefore, the Reporting Persons are no longer a 10% owner and are no longer subject to Section 16. This is an exit filing only with no transaction to be reported.</remarks>
