• One Helluva Expense Report: “Expense Reimbursements As a privately-owned firm, we have initially incurred or made payments for certain personal expenses on behalf of Messrs. Schwarzman and Peterson, which expenses were reimbursed by the executives. The maximum amounts outstanding under these arrangements in 2006 were $852,838 for Mr. Schwarzman and $345,870 for Mr. Peterson. No such amounts remain outstanding and the firm will no longer incur or make similar payments in respect of personal expenses.”
• Take My Jet, No Really: “Firm Use of Our Founders’ Private Aircraft Mr. Schwarzman owns an airplane and Messrs. Schwarzman and Peterson jointly own a helicopter that we use for business purposes in the course of our operations. Messrs. Schwarzman and Peterson paid for the purchase of these aircraft themselves and bear all operating, personnel and maintenance costs associated with their operation. The hourly payments we made to Mr. Schwarzman and Mr. Peterson for such use were based on current market rates for chartering private aircraft. We paid $1,544,320, $1,037,925 and $1,032,170 to Mr. Schwarzman in 2006, 2005 and 2004, respectively, for the use of his airplane and we paid $158,500, $306,210 and $198,905 to Mr. Schwarzman and Mr. Peterson in 2006, 2005 and 2004, respectively, for the use of their jointly-owned helicopter.”
