To estimate the fair value of long-term debt, we used the following valuation approaches:
market approach – based on quoted market prices for the same types and issues of our debt; or
income approach – based on the discounted value of the future cash flows using market yields for the same type and comparable issues of debt.
The inputs to the valuations are based on market data obtained from independent sources or information derived principally from observable market data.
The difference between the fair value and the carrying value represents the theoretical net premium or discount we would pay or receive to retire all debt at the measurement date.
At the beginning of June 2011, we exercised our right to call approximately $518 million of 6.75 percent notes due in 2012. We recognized a pretax charge in second quarter 2011 of $26 million, which included early retirement premiums, unamortized debt issuance costs and other miscellaneous charges in connection with the early extinguishment of debt. This charge is included in interest expense in the Consolidated Statement of Operations.
Real Estate debt maturities were $30 million for second quarter and $32 million for year-to-date 2011.


FAIR VALUE OF OTHER FINANCIAL INSTRUMENTS
We believe that our other financial instruments, including cash, short-term investments, receivables, and payables, have net carrying values that approximate their fair values with only insignificant differences. This is primarily due to:
the short-term nature of these instruments,
carrying short-term investments at expected net realizable value and
the allowance for doubtful accounts.
