¹: During the second quarter of 2010, SCE recognized a $53 million earnings benefit resulting from the acceptance by the California Franchise Tax Board of the tax positions finalized with the Internal Revenue Service ("IRS") in 2009 as part of the Global Settlement.
²: During the second quarter of 2010, the IRS approved SCE's request to change its tax accounting method for asset removal costs primarily related to its infrastructure replacement program. As a result, SCE recognized a $40 million earnings benefit (of which $28 million relates to asset removal costs incurred prior to 2010) from deducting asset removal costs earlier in the construction cycle. These deductions were recorded on a flow-through basis.
³: During the first quarter of 2010, SCE recorded a $39 million non-cash charge to reverse previously recognized federal tax benefits eliminated by the federal health care legislation enacted in March 2010. The health care law eliminated the federal tax deduction for retiree health care costs to the extent those costs are eligible for federal Medicare Part D subsidies.

The decreased benefit provided by property-related and other items was primarily due to lower deductions for internally developed software in 2011 compared to the respective periods in 2010.

The CPUC requires flow-through ratemaking treatment for the current tax benefit arising from certain property-related and other temporary differences which reverse over time. The accounting treatment for these temporary differences results in recording regulatory assets and liabilities for amounts that would otherwise be recorded to deferred income tax expense.

Accounting for Uncertainty in Income Taxes

Authoritative guidance related to accounting for uncertainty in income taxes requires an enterprise to recognize, in its financial statements, the best estimate of the impact of a tax position by determining if the weight of the available evidence indicates it is more likely than not, based solely on the technical merits, that the position will be sustained upon examination. The guidance requires the disclosure of all unrecognized tax benefits, which includes both the reserves recorded for tax positions on filed tax returns and the unrecognized portion of affirmative claims.

Unrecognized Tax Benefits

The following table provides a reconciliation of unrecognized tax benefits:

(in millions)		2011			2010


Balance at January 1,		$	329		$	482
Tax positions taken during the current year
	Increases		29			31
Tax positions taken during a prior year
	Increases		14			133
	Decreases		(11	)		(42	)
	Decreases for settlements during the period		—			(68	)

Balance at June 30,		$	361		$	536

As of June 30, 2011 and December 31, 2010 $240 million and $225 million, respectively, of the unrecognized tax benefits, if recognized, would impact the effective tax rate.

Edison International's federal income tax returns and its California combined franchise tax returns are currently open for years subsequent to 2002. In addition, specific California refund claims made by Edison International for years 1991 through 2002 are currently under review by the Franchise Tax Board. The IRS examination phase of tax years 2003 through 2006 was completed in the fourth quarter of 2010. This included a proposed adjustment to disallow a component of SCE's repair allowance deduction, which if sustained, would result in a federal tax payment of approximately $91 million, including interest through June 30, 2011. Edison International disagrees with the proposed adjustment and filed a protest with the IRS in the first quarter of 2011.

Accrued Interest and Penalties

The total amount of accrued interest and penalties related to SCE's income tax liabilities was $65 million and $61 million as of June 30, 2011 and December 31, 2010, respectively.

The net after-tax interest and penalties recognized in income tax expense was $2 million and $3 million for the three- and six-month periods ended June 30, 2011, respectively, compared to a benefit of $24 million and $22 million for the same periods in 2010.
