At June 30, 2011, we had $1.7 billion of committed revolving credit facilities with commercial banks. There were no direct borrowings under the committed revolving credit facilities during the six months ended June 30, 2011. We also have a commercial paper program under which we may issue up to $1.0 billion in commercial paper with maturity of no more than 270 days. To the extent we have outstanding commercial paper, our ability to borrow under the facilities is reduced. At June 30, 2011, we had no outstanding commercial paper.
