NOTE 8. FAIR VALUE MEASUREMENTS

Fair Value of Financial Instruments

The fair values of certain of our financial instruments (cash, temporary investments, accounts and notes receivable, dividends and accounts payable, short-term debt and customer deposits) approximate their carrying amounts. The following table provides the carrying amounts and fair values of the remaining financial instruments at June 30, 2011 and December 31, 2010:

(1)	We discuss our investments in affordable housing partnerships in Note 4 of the Notes to Consolidated Financial Statements in the Annual Report.
(2)	Before reductions for unamortized discount of $22 million at both June 30, 2011 and December 31, 2010, and excluding capital leases of $214 million at June 30, 2011 and $221 million at December 31, 2010, and commercial paper classified as long-term debt of $200 million at June 30, 2011 and $800 million at December 31, 2010. We discuss our long-term debt in Note 6 above and Note 5 of the Notes to Consolidated Financial Statements in the Annual Report.
(3)	Note payable was extinguished due to the increase in our ownership of Chilquinta Energía S.A. to 100% in the second quarter of 2011.
(4)	Before reductions for unamortized discount of $9 million at both June 30, 2011 and December 31, 2010, and excluding capital leases of $198 million at June 30, 2011 and $202 million at December 31, 2010.
(5)	Before reductions for unamortized discount of $2 million at June 30, 2011 and $3 million at December 31, 2010, and excluding capital leases of $15 million at June 30, 2011 and $19 million at December 31, 2010.

Sempra Energy based the fair values of investments in affordable housing partnerships on the present value of estimated future cash flows, discounted at rates available for similar investments. All entities based the fair values of long-term debt and preferred stock on their quoted market prices or quoted market prices for similar securities.

Nuclear Decommissioning Trusts

We discuss SDG&E's investments in nuclear decommissioning trust funds in Note 6 of the Notes to Consolidated Financial Statements in the Annual Report. The following table shows the fair values and gross unrealized gains and losses for the securities held in the trust funds:

(2)	Maturity dates are 2013-2057.
(3)	Maturity dates are 2011-2049.

The following table shows the proceeds from sales of securities in the trusts and gross realized gains and losses on those sales:

SALES OF SECURITIES
(Dollars in millions)
	Three months ended June 30,				Six months ended June 30,
	2011		2010		2011		2010
Proceeds from sales	$	48	$	110	$	90	$	150
Gross realized gains		1		2		2		3
Gross realized losses		(1)		(5)		(2)		(7)

Net unrealized gains (losses) are included in Regulatory Liabilities Arising from Removal Obligations on the Condensed Consolidated Balance Sheets. We determine the cost of securities in the trusts on the basis of specific identification.

Derivative Positions Net of Cash Collateral

Each Condensed Consolidated Balance Sheet reflects the offsetting of net derivative positions with fair value amounts for cash collateral with the same counterparty when management believes a legal right of offset exists.

The following table provides the amount of fair value of cash collateral receivables that were not offset in the Condensed Consolidated Balance Sheets as of June 30, 2011 and December 31, 2010:

	June 30,		December 31,
(Dollars in millions)	2011		2010
Sempra Energy Consolidated	$	30	$	32
SDG&E		18		25
SoCalGas		3		3

Fair Value Hierarchy

We discuss the valuation techniques and inputs we use to measure fair value and the definition of the three levels of the fair value hierarchy in Notes 1 and 2 of the Notes to Consolidated Financial Statements in the Annual Report. We have not changed the valuation techniques or inputs we use to measure fair value during the six months ended June 30, 2011.

The three tables below, by level within the fair value hierarchy, set forth our financial assets and liabilities that were accounted for at fair value on a recurring basis as of June 30, 2011 and December 31, 2010. We also discuss our financial assets and liabilities recorded at fair value on a non-recurring basis. We classify financial assets and liabilities in their entirety based on the lowest level of input that is significant to the fair value measurement. Our assessment of the significance of a particular input to the fair value measurement requires judgment, and may affect the valuation of fair value assets and liabilities, and their placement within the fair value hierarchy levels.

The fair value of commodity derivative assets and liabilities is determined in accordance with our netting policy, as discussed above under "Derivative Positions Net of Cash Collateral."

The determination of fair values, shown in the tables below, incorporates various factors, including but not limited to, the credit standing of the counterparties involved and the impact of credit enhancements (such as cash deposits, letters of credit and priority interests).

We provide detail about our financial assets and liabilities that were accounted for at fair value on a recurring basis in Note 11 of the Notes to Consolidated Financial Statements in the Annual Report.

Level 3 recurring items are related to CRRs. These instruments are recorded at fair value based on the most current annual auction prices published by the California Independent System Operator (ISO). The earnings impact of CRRs are deferred and recorded in regulatory accounts to the extent they are recoverable or refundable through rates. Upon settlement, CRRs are included in Cost of Electric Fuel and Purchased Power on the Condensed Consolidated Statements of Operations.
