Fair Value of Financial Instruments
8. Fair Value of Financial Instruments
    The carrying amount of cash and cash equivalents and accounts receivable, net of allowance for bad debts, approximates fair value because of the short maturities of those instruments.
    The estimated fair value of the Company’s $300.0 million principal amount of the 9.125% Notes, based on quoted market prices, was $316.5 million at June 30, 2011. The estimated fair value, based upon quoted prices, of the Company’s $125.0 million principal amount of the 2.125% Notes, was $123.7 million on June 30, 2011.
    The carrying amount of our interest rate swap agreements represents the estimated fair value, measured using Level 2. At June 30, 2011, the carrying amount of our interest rate swap agreements was $0.1 million, recorded in other long-term liabilities on our consolidated condensed balance sheets. We did not have any outstanding derivative instruments as of June 30, 2010.
