INCOME TAXES

In determining quarterly provisions for income taxes, Kennedy-Wilson uses an effective tax rate based on actual year-to-date income and statutory tax rates. The effective tax rate also reflects Kennedy-Wilson's assessment of the ultimate outcome of tax audits.

Kennedy Wilson's effective tax rates for the three month periods ended September 30, 2011 and 2010 were 38.1% and 11.4%, respectively. Kennedy-Wilson's effective tax rates for the nine months ended September 30, 2011 and 2010 were 48.6% and 55.1%, respectively. The fluctuations between periods in the Company's effective tax rate are mainly due to varying levels of income and amounts attributable to non-controlling interests. Permanent items that impact the Company's effective rates as compared to the U.S. federal statutory rate of 34% were not materially different in amounts for all periods. The difference between the U.S. federal statutory rate of 34% and the Company's effective tax rate are state taxes and income attributable to non-controlling interests.
