Debt and Credit Facilities	7. DEBT AND CREDIT FACILITIES Material changes, if any, to Progress Energy's, PEC's and PEF's debt and credit facilities and financing activities since December 31, 2010, are as follows. On January 21, 2011, the Parent issued $500 million of 4.40% Senior Notes due January 15, 2021. The net proceeds, along with available cash on hand, were used to retire the $700 million outstanding aggregate principal balance of our 7.10% Senior Notes due March 1, 2011. On May 3, 2011, $22 million of the Parent's $500 million revolving credit agreement (RCA) expired, leaving the Parent with total credit commitments of $478 million supported by 14 financial institutions. After the $22 million expiration, our combined credit commitments for the Parent, PEC and PEF are $1.978 billion, supported by 23 financial institutions. On July 15, 2011, PEF paid at maturity $300 million of its 6.65% First Mortgage Bonds with proceeds from commercial paper borrowings. On August 18, 2011, PEF issued $300 million 3.10% First Mortgage Bonds due August 15, 2021. The net proceeds were used to repay a portion of outstanding short-term debt, of which $300 million was issued to repay PEF's July 15, 2011 maturity. On September 15, 2011, PEC issued $500 million 3.00% First Mortgage Bonds due September 15, 2021. A portion of the net proceeds was used to repay outstanding short-term debt and the remainder was placed in temporary investments for general corporate use as needed, including construction expenditures. On September 30, 2011, the current portion of our long-term debt was $950 million (including $500 million at PEC). We expect to fund the current portion of long-term debt with a combination of cash from operations, commercial paper borrowings and/or long-term debt.
