Blackstone’s effective tax rate was 11.1% and 16.6% for the three months ended September 30, 2013 and 2012, respectively, and 10.5% and 14.4% for the nine months ended September 30, 2013 and 2012, respectively. Blackstone’s income tax provision was $57.5 million and $39.2 million for the three months ended September 30, 2013 and 2012, respectively, and $164.6 million and $119.3 million for the nine months ended September 30, 2013 and 2012, respectively.

Blackstone’s effective tax rate for the three and nine months ended September 30, 2013 and 2012 was substantially due to the following: (a) certain corporate subsidiaries are subject to federal, state, local and foreign income taxes as applicable and other subsidiaries are subject to New York City unincorporated business taxes, and (b) a portion of compensation charges are not deductible for tax purposes.
