Debt and Credit Facilities	NOTE 6. DEBT AND CREDIT FACILITIES Committed Lines of Credit At September 30, 2011, Sempra Energy Consolidated had $3.8 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, 2011 was $2.7 billion. Sempra Energy Sempra Energy has a $1 billion, four-year syndicated revolving credit agreement expiring in October 2014. Citibank, N.A. serves as administrative agent for the syndicate of 23 lenders. No single lender has greater than a 7-percent share. 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 $400 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, 2011, Sempra Energy had $14 million of variable-rate demand notes outstanding supported by the facility. Sempra Global Sempra Global has a $2 billion, four-year syndicated revolving credit agreement expiring in October 2014. Citibank, N.A. serves as administrative agent for the syndicate of 23 lenders. No single lender has greater than a 7-percent share. 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, 2011, Sempra Global had $823 million of commercial paper outstanding supported by the facility. At September 30, 2011, $200 million of the commercial paper outstanding is 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. At December 31, 2010, $800 million of commercial paper outstanding was similarly classified as long-term debt. Sempra Utilities SDG&E and SoCalGas have a combined $800 million, four-year syndicated revolving credit agreement expiring in October 2014. JPMorgan Chase Bank serves as administrative agent for the syndicate of 22 lenders. No single lender has greater than a 7-percent share. The agreement permits each utility to individually borrow up to $600 million, subject to a combined limit of $800 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. 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, 2011, SDG&E and SoCalGas had no outstanding borrowings under this facility and SDG&E had $237 million of variable-rate demand notes outstanding supported by the facility. Available unused credit on the lines under this facility at September 30, 2011 was $363 million at SDG&E and $563 million at SoCalGas; SoCalGas' availability reflects the impact of SDG&E's use of the combined credit available on the line. 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 are, subject to certain qualifications, obligated to replace any guarantees that we have issued in connection with the applicable businesses sold with guarantees of their own. During the process of replacing these guarantees, the buyers are obligated to indemnify us in accordance with the applicable transaction documents for any claims or losses in connection with the guarantees. RBS is obligated to provide RBS Sempra Commodities with certain of its working-capital requirements. 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. RBS Sempra Commodities' net trading liabilities supported by Sempra Energy's guarantees at September 30, 2011 were $15 million, consisting of guaranteed trading obligations net of collateral. The amount of guaranteed net trading liabilities varies from day to day with the value of the trading obligations and related collateral. Other Guarantees Sempra Generation and BP Wind Energy currently hold 50-percent ownership interests in Fowler Ridge 2. In August 2010, Fowler Ridge 2 obtained a $348 million term loan expiring in August 2022. The proceeds were used to return $180 million of each owner's investment in the joint venture. The loan agreement requires Sempra Generation and BP Wind Energy to return cash to the project in the event that the project does not meet certain cash flow criteria or in the event that the project's debt service and operation and maintenance reserve accounts are not maintained at specific thresholds. Sempra Generation recorded a liability of $9 million for the fair value of its obligation associated with the cash flow requirements, which constitutes a guarantee. This liability is being amortized over its expected life. The outstanding loan is not guaranteed by the partners. WEIGHTED AVERAGE INTEREST RATES The weighted average interest rates on the total short-term debt outstanding at Sempra Energy were 0.67 percent and 0.46 percent at September 30, 2011 and December 31, 2010, respectively. The weighted average interest rates at both September 30, 2011 and December 31, 2010 include interest rates for commercial paper borrowings classified as long-term, as we discuss above. LONG-TERM DEBT In August 2011, SDG&E publicly offered and sold $350 million of 3-percent first mortgage bonds maturing in 2021. In March 2011, Sempra Energy publicly offered and sold $500 million of 2-percent notes and $300 million of floating rate notes (1.11 percent as of September 30, 2011), both maturing in 2014. The floating rate notes bear interest at a rate equal to the three-month London interbank offered rate (LIBOR) plus 0.76 percent. The interest rate is reset quarterly. Luz del Sur has outstanding Peruvian corporate bonds, denominated in the local currency, registered with the Peruvian stock exchange with maturity dates ranging from 2011 to 2015 at fixed interest rates ranging from 5.78 percent to 7.91 percent. As of September 30, 2011, the outstanding balance on these bonds was $168 million.

Chilquinta Energía has outstanding Series A and Series B Chilean public bonds with maturity dates in 2014 and 2030, respectively, and stated interest rates of 2.75 percent and 4.25 percent, respectively. The bonds and related interest are denominated in Chilean Unidades de Fomento. The Chilean Unidad de Fomento is a unit of account used in Chile that is adjusted for inflation, and its value is quoted in Chilean Pesos. In 2009, Sempra Pipelines & Storage purchased $58 million of the 2.75-percent bonds, which are eliminated in consolidation. Net of this elimination, as of September 30, 2011, the outstanding balance on these bonds was $221 million ($23 million of Series A and $198 million of Series B). In September 2011, Mobile Gas privately placed $20 million of 4.14-percent first mortgage bonds and $42 million of 5-percent first mortgage bonds, maturing in 2021 and 2031, respectively.
