Our long-term debt is presented in the table above net of unamortized discounts from par and unamortized deferred gains realized upon settlement of interest rate swaps. Discounts, deferred gains and debt issuance costs are being amortized using the effective interest method over the respective terms of the notes.

The estimated fair value of long-term debt presented in the table above was determined by averaging price quotes for the notes. The fair value estimates were based on Level 2 information (as defined in Note 6) available to us as of the respective balance sheet dates. Although we are not aware of any factors that would significantly affect the estimated fair value amounts, such amounts have not been comprehensively revalued since those dates.

During 2011, we replaced our $1,500,000,000 bank line of credit that was set to expire on November 16, 2012 with a $600,000,000 bank line of credit. The $600,000,000 bank line of credit expires on December 15, 2016 and is secured by certain domestic accounts receivable and inventory. Borrowing capacity fluctuates with the level of eligible accounts receivable and inventory and may be less than $600,000,000 at any point in time.

Borrowings under the $600,000,000 bank line of credit bear interest at a rate determined at the time of borrowing equal to the lower of LIBOR plus a margin ranging from 1.75% to 2.25% based on the level of utilization, or an alternative rate derived from the lender’s prime rate. Borrowings bearing interest at LIBOR plus the margin are made for periods of 1, 2, 3 or 6 months, and may be extended. Borrowings bearing interest at the alternative rate are made on an overnight basis and may be extended each day. As of September 30, 2012, the applicable margin for LIBOR based borrowing was 1.75%.

Borrowings under the $600,000,000 bank line of credit are classified as long-term debt due to our ability to extend borrowings at the end of each borrowing period. Prior to December 31, 2011, we classified bank line of credit borrowings as short-term debt based on our intent to pay outstanding borrowings within one year.

In June 2011, we issued $1,100,000,000 of long-term notes in two series, as follows: $500,000,000 of 6.50% notes due in 2016 and $600,000,000 of 7.50% notes due in 2021. These notes were issued principally to:

repay and terminate our $450,000,000 floating-rate term loan due in 2015

fund the purchase through a tender offer of $165,443,000 of our outstanding 5.60% notes due in 2012 and $109,556,000 of our outstanding 6.30% notes due in 2013

repay $275,000,000 outstanding under our revolving credit facility

and for general corporate purposes

Unamortized deferred financing costs of $2,423,000 associated with the terminated $450,000,000 floating-rate term loan were recognized in June 2011 as a component of interest expense upon the termination of this floating-rate term loan.

The June 2011 purchases of the 5.60% and 6.30% notes cost $294,533,000, including a $19,534,000 premium above the $274,999,000 face value of the notes. This premium primarily reflects the trading price of the notes at the time of purchase relative to par value. Additionally, $4,711,000 of expense associated with a proportional amount of unamortized discounts, deferred financing costs and amounts accumulated in OCI was recognized in June 2011 upon the partial termination of the notes. The combined expense of $24,245,000 was recognized as a component of interest expense in June 2011.
