Debt and Credit Facilities	NOTE 6. DEBT AND CREDIT FACILITIES Committed Lines of Credit At March 31, 2012, Sempra Energy Consolidated had $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 March 31, 2012 was $3.4 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 replaces the $1.0 billion credit agreement set 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 $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 March 31, 2012, Sempra Energy had $2 million of variable-rate demand notes 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 replaces the $2.0 billion credit agreement set 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 March 31, 2012, Sempra Global had $417 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 three months ended March 31, 2012, as we discuss below, none of the commercial paper outstanding at March 31, 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 replaces the $800 million combined credit agreement set 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 March 31, 2012, SDG&E and SoCalGas had no outstanding borrowings and SDG&E had $237 million variable-rate demand notes outstanding supported by the facility. Available unused credit on the lines at March 31, 2012 was $421 million at SDG&E and $640 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 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 substantially completed this process in 2011 with regard to existing, open positions. 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 March 31, 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. RBS Sempra Commodities' net trading liabilities supported by Sempra Energy's guarantees at March 31, 2012 were negligible, 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. 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 0.72 percent and 0.93 percent at March 31, 2012 and December 31, 2011, respectively. The weighted average interest rates at December 31, 2011 include interest rates for commercial paper borrowings classified as long-term, as we discuss above. LONG-TERM DEBT In March 2012, Sempra Energy publicly offered and sold $600 million of 2.3-percent notes maturing in 2017. In March 2012, SDG&E publicly offered and sold $250 million of 4.3-percent first mortgage bonds maturing in 2042. INTEREST RATE SWAPS We discuss our fair value interest rate swaps and interest rate swaps to hedge cash flows in Note 7.
