Debt and lines of credit
Short-term borrowings
We maintain a line of credit to support commercial paper borrowings, if any, and to provide additional liquidity through bank loans. As of December 31, 2013, we had a variable-rate revolving credit facility from a consortium of investment-grade banks that allows us to borrow up to $2 billion through March 2018. The interest rate on borrowings under this credit facility, if drawn, is indexed to the applicable London Interbank Offered Rate (LIBOR). As of December 31, 2013, our credit facility was undrawn and we had no commercial paper outstanding.
Long-term debt
In May 2013, we issued an aggregate principal amount of $1.0 billion of fixed-rate long-term debt, with $500 million due in 2018 and $500 million due in 2023. We also incurred $6 million of issuance and other related costs that are being amortized to Interest and debt expense over the term of the debt. The proceeds of the offering were $986 million, net of the original issuance discount and were used toward the repayment of $1.5 billion of maturing debt, including floating-rate notes. In connection with this repayment, we settled a floating-to-fixed interest rate swap, associated with the maturing debt.
In August 2012, we issued an aggregate principal amount of $1.5 billion of fixed-rate long-term debt, with $750 million due in 2015 and $750 million due in 2019. The proceeds of the offering were $1.492 billion, net of the original issuance discount. We also incurred $7 million of issuance and other related costs that are being amortized to Interest and debt expense over the term of the debt.
