    <remarks>On September 5, 2019, Apollo Global Management, LLC converted from a Delaware limited liability company to a Delaware corporation (the &quot;Conversion&quot;) and changed its name to Apollo Global Management, Inc. As a result of the Conversion, each Class A share of Apollo Global Management, LLC was converted into a share of Class A common stock of Apollo Global Management, Inc.  Following the Conversion, tax-free exchanges of AOG units under the Fifth A&amp;R Exchange Agreement, as further amended and restated, will no longer be possible.  Accordingly, Mr. Kleinman has elected to direct the exchange of AOG units in connection with the Conversion.  The AOG units were exchanged for shares of Class A common stock solely for purposes of charitable contributions.  It is Mr. Kleinman's intent to contribute the shares to charity or a donor advised fund over time.</remarks>
