9. 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 March 31, 2015, we had a variable-rate revolving credit facility from a consortium of investment-grade banks that allows us to borrow up to $2 billion until March 2020. The interest rate on borrowings under this credit facility, if drawn, is indexed to the applicable London Interbank Offered Rate (LIBOR). As of March 31, 2015, our credit facility was undrawn and we had no commercial paper outstanding.

Long-term debt

In March 2014, we issued an aggregate principal amount of $500 million of fixed-rate long-term debt, with $250 million due in 2017 and $250 million due in 2021. We incurred $3 million of issuance and other related costs, which are amortized to Interest and debt expense over the term of the debt. The proceeds of the offering were $498 million, net of the original issuance discount and were used toward the repayment of the $1 billion of debt that matured in May 2014.

Long-term debt outstanding is as follows:

	March 31,			December 31,
	2015			2014
Notes due 2015 at 3.95% (assumed with National acquisition)	$	250		$	250
Notes due 2015 at 0.45%		750			750
Notes due 2016 at 2.375%		1,000			1,000
Notes due 2017 at 6.60% (assumed with National acquisition)		375			375
Notes due 2017 at 0.875%		250			250
Notes due 2018 at 1.00%		500			500
Notes due 2019 at 1.65%		750			750
Notes due 2021 at 2.75%		250			250
Notes due 2023 at 2.25%		500			500
Total debt		4,625			4,625
Net unamortized premium		13			17
Current portion of long-term debt		(1,000	)		(1,001	)
Long-term debt	$	3,638		$	3,641

Interest and debt expense was $22 million and $25 million for the three months ended March 31, 2015 and 2014, respectively. This was net of the amortization of the debt premium and other debt issuance costs. Capitalized interest was not material.
