Debt and Credit Facilities	NOTE 6. DEBT AND CREDIT FACILITIES Committed Lines of Credit At September 30, 2012, Sempra Energy Consolidated had an aggregate of $4.1 billion in committed lines of credit to provide liquidity and to support commercial paper and variable-rate demand notes, the major components of which we detail below. Available unused credit on these lines at September 30, 2012 was $3.5 billion. Sempra Energy In March 2012, Sempra Energy entered into a new $1.067 billion, five-year syndicated revolving credit agreement expiring in March 2017. Citibank, N.A. serves as administrative agent for the syndicate of 24 lenders. No single lender has greater than a 7-percent share. The new facility replaced the $1.0 billion credit agreement that was scheduled to expire in 2014. Borrowings bear interest at benchmark rates plus a margin that varies with market index rates and Sempra Energy's credit ratings. The facility requires Sempra Energy to maintain a ratio of total indebtedness to total capitalization (as defined in the agreement) of no more than 65 percent at the end of each quarter. The facility also provides for issuance of up to $700 million of letters of credit on behalf of Sempra Energy with the amount of borrowings otherwise available under the facility reduced by the amount of outstanding letters of credit. At September 30, 2012, Sempra Energy had $47 million of letters of credit outstanding supported by the facility. Sempra Global In March 2012, Sempra Global entered into a $2.189 billion, five-year syndicated revolving credit agreement expiring in March 2017. Citibank, N.A. serves as administrative agent for the syndicate of 25 lenders. No single lender has greater than a 7-percent share. The new facility replaced the $2.0 billion credit agreement that was scheduled to expire in 2014. Sempra Energy guarantees Sempra Global's obligations under the credit facility. Borrowings bear interest at benchmark rates plus a margin that varies with market index rates and Sempra Energy's credit ratings. The facility requires Sempra Energy to maintain a ratio of total indebtedness to total capitalization (as defined in the agreement) of no more than 65 percent at the end of each quarter. At September 30, 2012, Sempra Global had $545 million of commercial paper outstanding supported by the facility. At December 31, 2011, $400 million of commercial paper outstanding was classified as long-term debt based on management's intent and ability to maintain this level of borrowing on a long-term basis either supported by this credit facility or by issuing long-term debt. This classification has no impact on cash flows. As a result of issuances of long-term debt in the nine months ended September 30, 2012, as we discuss below, none of the commercial paper outstanding at September 30, 2012 is classified as long-term debt. California Utilities In March 2012, SDG&E and SoCalGas entered into a new combined $877 million, five-year syndicated revolving credit agreement expiring in March 2017. JPMorgan Chase Bank, N.A. serves as administrative agent for the syndicate of 24 lenders. No single lender has greater than a 7-percent share. The agreement permits each utility to individually borrow up to $658 million, subject to a combined limit of $877 million for both utilities. It also provides for the issuance of letters of credit on behalf of each utility subject to a combined letter of credit commitment of $200 million for both utilities. The amount of borrowings otherwise available under the facility is reduced by the amount of outstanding letters of credit. The new facility replaced the $800 million combined credit agreement that was scheduled to expire in 2014. Borrowings under the facility bear interest at benchmark rates plus a margin that varies with market index rates and the borrowing utility's credit ratings. The agreement requires each utility to maintain a ratio of total indebtedness to total capitalization (as defined in the agreement) of no more than 65 percent at the end of each quarter. Each utility's obligations under the agreement are individual obligations, and a default by one utility would not constitute a default by the other utility or preclude borrowings by, or the issuance of letters of credit on behalf of, the other utility. At September 30, 2012, SoCalGas had no outstanding borrowings and SDG&E had $2 million of commercial paper outstanding supported by the facility. Available unused credit on the line at September 30, 2012 was $656 million at SDG&E and $658 million at SoCalGas, subject to the combined limit on the facility of $877 million. GUARANTEES RBS Sempra Commodities As we discuss in Note 4, in 2010 and early 2011, Sempra Energy, RBS and RBS Sempra Commodities sold substantially all of the businesses and assets within the partnership in four separate transactions. In connection with each of these transactions, the buyers were, subject to certain qualifications, obligated to replace any guarantees that we had issued in connection with the applicable businesses sold with guarantees of their own. The buyers have substantially completed this process with regard to all existing, open positions, except for one remaining position expected to terminate by January 2013. For those guarantees which have not been replaced, the buyers are obligated to indemnify us in accordance with the applicable transaction documents for any claims or losses in connection with the guarantees that we issued associated with the businesses sold. At September 30, 2012, RBS Sempra Commodities no longer requires significant working capital support. However, we have provided back-up guarantees for a portion of RBS Sempra Commodities' remaining trading obligations. A few of these back-up guarantees may continue for a prolonged period of time. RBS has fully indemnified us for any claims or losses in connection with these arrangements, with the exception of those obligations for which JP Morgan has agreed to indemnify us. We discuss the indemnification release in Note 4. We discuss additional matters related to our investment in RBS Sempra Commodities in Note 10. WEIGHTED AVERAGE INTEREST RATES The weighted average interest rates on the total short-term debt outstanding at Sempra Energy were 0.82 percent and 0.93 percent at September 30, 2012 and December 31, 2011, respectively. The weighted average interest rate on the total short-term debt outstanding at SDG&E was 0.2 percent at September 30, 2012. The weighted average interest rates at Sempra Energy at December 31, 2011 include interest rates for commercial paper borrowings classified as long-term, as we discuss above. LONG-TERM DEBT Sempra Energy In March 2012, Sempra Energy publicly offered and sold $600 million of 2.30-percent notes maturing in 2017. In September 2012, Sempra Energy publicly offered and sold $500 million of 2.875-percent notes maturing in 2022. SDG&E In March 2012, SDG&E publicly offered and sold $250 million of 4.30-percent first mortgage bonds maturing in 2042. In September 2012, SDG&E remarketed $161 million of variable rate demand notes at a fixed rate of 1.65 percent maturing in 2018 and $75 million of variable rate demand notes at a fixed rate of 4.00 percent maturing in 2039. SoCalGas In September 2012, SoCalGas publicly offered and sold $350 million of 3.75-percent first mortgage bonds maturing in 2042. Sempra South American Utilities In February 2012, Luz del Sur publicly offered and sold Peruvian corporate bonds, denominated in the local currency, in the amounts of $21 million at 5.97 percent maturing in 2017 and $9 million at 6.34 percent maturing in 2019. In July 2012, Luz del Sur publicly offered and sold $25 million of Peruvian corporate bonds, denominated in the local currency, at 5.44 percent and maturing in 2019. Sempra Renewables In June 2012, Sempra Renewables obtained a $117 million loan, the proceeds of which were applied to construction costs of the Copper Mountain Solar 1 project. The loan fully matures in December 2028. To partially moderate its exposure to interest rate changes, Sempra Renewables has also entered into floating-to-fixed interest rate swaps maturing December 2028. Accordingly, $88 million of this loan has interest rates that are effectively fixed at 4.54 percent. The remaining balance bears interest at rates varying with market rates (2.86 percent at September 30, 2012). INTEREST RATE SWAPS We discuss our fair value interest rate swaps and interest rate swaps to hedge cash flows in Note 7.
