Current maturities of long-term debt of $1.51 billion were repaid during the year ended December 31, 2012.

The aggregate amounts of maturities on long-term debt for the next five years are $1.01 billion in 2014, $9.5 million in 2015, $205.6 million in 2016, $1.00 billion in 2017, and $200.3 million in 2018.

At December 31, 2013, we have $1.36 billion of unused committed bank credit facilities, $1.20 billion of which is a revolving credit facility that backs our commercial paper program and matures in April 2015. There were no amounts outstanding under the revolving credit facility during the year ended December 31, 2013. Compensating balances and commitment fees are not material, and there are no conditions that are probable of occurring under which the lines may be withdrawn.

We have converted approximately 65 percent of all fixed-rate debt to floating rates through the use of interest rate swaps. The weighted-average effective borrowing rates based on debt obligations and interest rates at December 31, 2013 and 2012, including the effects of interest rate swaps for hedged debt obligations, were 3.10 percent and 3.20 percent, respectively.

For the years ended December 31, 2013, 2012, and 2011, cash payments for interest on borrowings totaled $139.7 million, $171.9 million, and $167.4 million, respectively, net of capitalized interest.

In accordance with the requirements of derivatives and hedging guidance, the portion of our fixed-rate debt obligations that is hedged, as a fair value hedge, is reflected in the consolidated balance sheets as an amount equal to the sum of the debt’s carrying value plus the fair value adjustment representing changes in fair value of the hedged debt attributable to movements in market interest rates subsequent to the inception of the hedge.
