(a) As of June 30, 2013 and December 31, 2012, the interest rate on the 11.25% senior notes due February 1, 2019 was 12.50% as a result of downgrades in the ratings of the notes by the rating agencies.

(b) Includes miscellaneous debt obligations, capital leases and fair value adjustments to the 4.95% senior notes due April 1, 2014 and 8.25% senior notes due March 15, 2019 related to the Company’s fair value hedges.

The fair values of the senior notes and debentures, which were determined using the market approach based upon interest rates available to the Company for borrowings with similar terms and maturities, were determined to be Level 2 under the fair value hierarchy. The fair value of the Company’s debt was greater than its book value by approximately $163.1 million and less than its book value by approximately $3.7 million at June 30, 2013 and December 31, 2012, respectively.

On March 14, 2013, the Company issued $450.0 million of 7.875% senior notes due March 15, 2021. Interest on the notes is payable semi-annually on March 15 and September 15 of each year, commencing on September 15, 2013. The net proceeds from the offering were used to repurchase $173.5 million of the 6.125% senior notes due January 15, 2017, $130.2 million of the 8.60% senior notes due August 15, 2016 and $50.0 million of the 7.25% senior notes due May 15, 2018 and to reduce borrowings under the Company’s $1.15 billion senior secured revolving credit facility (the “Credit Agreement”). The repurchases resulted in a pre-tax loss on debt extinguishment of $35.6 million for the six months ended June 30, 2013 related to the premiums paid, unamortized debt issuance costs and other expenses.

There were no borrowings outstanding under the Credit Agreement as of June 30, 2013 or December 31, 2012. The weighted average interest rate on borrowings under the Credit Agreement and the Company’s previous $1.75 billion revolving credit facility (the “Previous Credit Agreement”) during the six months ended June 30, 2013 and 2012 was 2.04% and 2.07%, respectively.

On March 13, 2012, the Company issued $450.0 million of 8.25% senior notes due March 15, 2019. Interest on the notes is payable semi-annually on March 15 and September 15 of each year, commencing on September 15, 2012. The net proceeds from the offering and cash on hand were used to repurchase $341.8 million of the 4.95% senior notes due April 1, 2014 and $100.0 million of the 5.50% senior notes due May 15, 2015. The repurchases resulted in a pre-tax loss on debt extinguishment of $12.1 million for the six months ended June 30, 2012, consisting of a loss of $23.2 million related to the premiums paid, unamortized debt issuance costs and other expenses, partially offset by the elimination of $11.1 million of the fair value adjustment on the 4.95% senior notes.

On January 15, 2012, proceeds from borrowings under the Company’s Previous Credit Agreement were used to pay the $158.6 million 5.625% senior notes that matured on January 15, 2012.

Interest income was $2.5 million and $6.3 million for the three and six months ended June 30, 2013 respectively. Interest income was $4.1 million and $7.7 million for the three and six months ended June 30, 2012, respectively.
