The Reporting Person is party to certain agreements with the Separately Filing Group Members (as defined in the Schedule 13D), which agreements contain, among other things, certain voting agreements and limitations on the sale of their shares of Common Stock. As a result, the Reporting Person may be deemed to be a member of a “group,” within the meaning of Section 13(d)(3) of the Act (as defined in the Schedule 13D), comprised of the Reporting Person and the Separately Filing Group Members. Shares listed as beneficially owned by the Reporting Person exclude shares held by any other Reporting Person or by any of the Separately Filing Group Members, in each case as to which the Reporting Person disclaims beneficial ownership.
All references to the number of shares outstanding are as of August 19, 2016, as reported in the Issuer’s Current Report on Form 8-K, filed August 22, 2016. The percentage is calculated using the total number of shares of Common Stock beneficially owned by the Reporting Person and based on 130,864,737 shares of Common Stock outstanding as of August 19, 2016. With respect to matters upon which the Issuer’s stockholders are entitled to vote, the holders of Class A Common Stock and Class B Common Stock vote together as a single class, and each holder of Class A Common Stock is entitled to one vote per share and each holder of Class B Common Stock is entitled to ten votes per share. The shares of Class B Common Stock owned by the Reporting Person represent 15.5% of the total voting power of the Common Stock as of August 19, 2016. The percentage of total voting power of the Common Stock is calculated based on the total voting power of the Common Stock outstanding as of August 19, 2016, which is comprised of 23,117,411 shares of Class A Common Stock and 107,747,326 shares of Class B Common Stock and assumes that no outstanding shares of Class B Common Stock have been converted into shares of Class A Common Stock.

7  	See the Schedule 13D filed on August 26, 2010, as amended, by Marshall E. Eisenberg, not individually, but solely as trustee of certain trusts listed on Appendix A-1 to the Schedule 13D, and the other Reporting Persons named therein, which includes information regarding the filer’s jurisdiction of organization, principal business, and address of principal office. Thomas J. Pritzker holds 119,707 stock appreciation rights (“ SARs ”) that are currently exercisable at an exercise price of $40.96, 127,410 SARs that are currently exercisable at an exercise price of $41.74, 140,601 SARs that are currently exercisable at an exercise price of $41.29, 155,535 SARs that are currently exercisable at an exercise price of $43.44, 70,095 SARs that are currently exercisable at an exercise price of $49.39 and 45,088 SARs that are currently exercisable at an exercise price of $56.27. The number of shares of Class A Common Stock that Mr. Pritzker will receive upon exercise of such SARs is not currently determinable and therefore not included in the table above because each SAR gives the holder the right to receive a number of shares of Class A Common Stock equal to the excess of the value of one share of A Common Stock at the exercise date, which is not determinable until the date of exercise, over the exercise price.
