On May 24, 2011 Aon entered into an underwriting agreement for the sale of $500 million of 3.125% unsecured Senior Notes due 2016 (the “Notes”).  On June 15, 2011, Aon entered into a Term Credit Agreement for unsecured term loan financing of $450 million (“2011 Term Loan Facility”) due on October 1, 2013.  The 2011 Term Loan Facility is a variable rate loan which is based on LIBOR plus a margin and at June 30, 2011, the effective annualized rate was approximately 1.56%.  The Company used the net proceeds from the Notes issuance and 2011 Term Loan Facility borrowings to repay all amounts outstanding under its $1.0 billion three-year credit agreement dated August 13, 2010 (“2010 Term Loan Facility”), which was entered into in connection with the acquisition of Hewitt.  The Company recorded a $19 million loss on the extinguishment of the 2010 Term Loan Facility as a result of the write-off of the related deferred financing costs, which is included in Other income (expense) in the Consolidated Statements of Income.
