(a) In February 2011, the Pennsylvania Department of Revenue issued interpretive guidance on the treatment of bonus depreciation for Pennsylvania income tax purposes. In accordance with Corporation Tax Bulletin 2011-01, Pennsylvania allows 100% bonus depreciation for qualifying assets in the same year bonus depreciation is allowed for federal tax purposes. Due to the decrease in projected taxable income related to bonus depreciation, PPL recorded state deferred income tax expense during the six months ended June 30, 2011 related to valuation allowances.

Additionally, the 100% Pennsylvania bonus depreciation deduction created a current state income tax benefit for the flow-through impact of Pennsylvania regulated state tax depreciation. The federal provision for 100% bonus depreciation generally applies to property placed into service before January 1, 2012. The placed in service deadline is extended to January 1, 2013 for property that exceeds $1 million, has a production period longer than one year and has a tax life of at least ten years.

(b) The U.K. Finance Act of 2011, enacted in July 2011, reduced the U.K. statutory income tax rate from 27% to 26% retroactive to April 1, 2011 and from 26% to 25% effective April 1, 2012.

The U.K. Finance Act of 2010, enacted in July 2010, reduced the U.K. statutory income tax rate from 28% to 27% effective April 1, 2011.

(c) During the three and six months ended June 30, 2011, PPL recorded a $7 million and $14 million federal income tax benefit related to U.K. pension contributions.

(d) During the three and six months ended June 30, 2012, PPL recorded a tax benefit following resolution of a U.K. tax issue related to interest expense.

(e) During the six months ended June 30, 2012, PPL recorded an adjustment related to state deferred tax liabilities.

(f) During the three and six months ended June 30, 2012, PPL recorded adjustments to deferred taxes related to net operating loss carryforwards of LKE based on income tax return adjustments.

(g) During the three and six months ended June 30, 2011, PPL recorded non-deductible acquisition-related costs (primarily the U.K. stamp duty tax) associated with its acquisition of WPD Midlands.

PPL has evaluated the impact of the change in earnings estimates on its projected annual effective tax rate. The result of the change in estimate reduced income tax expense for the three months ended June 30, 2012 by $13 million ($0.02 per share, basic and diluted).

In July 2012, the U.K. Finance Act of 2012 (the Act) was enacted. The Act reduced the U.K.'s statutory income tax rate from 25% to 24%, effective April 1, 2012 and from 24% to 23%, effective April 1, 2013. As a result of these changes, PPL expects to record a deferred tax benefit in the range of $65 million to $75 million in the third quarter of 2012.

Unrecognized Tax Benefits (PPL, PPL Energy Supply, PPL Electric, LKE, LG&E and KU)

(a) Represents unrecognized tax benefits derecognized as a result of PPL Energy Supply's distribution of its membership interest in PPL Global to PPL Energy Supply's parent, PPL Energy Funding. See Note 9 in PPL Energy Supply's 2011 Form 10-K for additional information on the distribution.

LKE's, LG&E's and KU's unrecognized tax benefits and changes in those unrecognized tax benefits are insignificant for the three and six months ended June 30, 2012 and 2011.

At June 30, 2012, it was reasonably possible that during the next 12 months the total amount of unrecognized tax benefits could increase or decrease by the following amounts. For LKE, LG&E and KU, no significant changes in unrecognized tax benefits are projected over the next 12 months.

These potential changes could result from subsequent recognition, derecognition and/or changes in the measurement of uncertain tax positions related to the creditability of foreign taxes, the timing and utilization of foreign tax credits and the related impact on alternative minimum tax and other credits, the timing and/or valuation of certain deductions, intercompany transactions and unitary filing groups. The events that could cause these changes are direct settlements with taxing authorities, litigation, legal or administrative guidance by relevant taxing authorities and the lapse of an applicable statute of limitation.

At June 30, the total unrecognized tax benefits and related indirect effects that, if recognized, would decrease the effective tax rate were as follows. The amounts for LKE, LG&E and KU were insignificant.

PPL changed its method of accounting for repair expenditures for tax purposes effective for its 2008 tax year for the Pennsylvania generation, transmission and distribution operations. The same change was made for the Montana generation operations for 2009.

In August 2011, the IRS issued Rev. Procs. 2011-42 and 2011-43. Rev. Proc. 2011-42 provides guidance regarding the use and evaluation of statistical samples and sampling estimates. Rev. Proc. 2011-43 provides a safe harbor method of determining whether the repair expenditures for electric transmission and distribution property can be currently deducted for tax purposes. PPL will adopt the safe harbor method with the filing of its 2011 federal income tax return, expected to occur in the third quarter of 2012. The adoption of the safe harbor method is not expected to result in a material change to income tax expense.

The IRS has not issued guidance to provide a safe harbor method for repair expenditures for generation property. The IRS may assert and ultimately conclude that PPL's deduction for generation-related expenditures should be disallowed in whole or in part. PPL believes that it has established an adequate reserve for this contingency.

In 1997, the U.K. imposed a Windfall Profits Tax (WPT) on privatized utilities, including WPD. PPL filed its tax returns for years subsequent to its 1997 and 1998 claim for refund on the basis that the U.K. WPT was creditable. In September 2010, the U.S. Tax Court (Tax Court) ruled in PPL's favor in a dispute with the IRS, concluding that the U.K. WPT is a creditable tax for U.S. tax purposes. As a result, and with finalization of other issues, PPL recorded a $42 million tax benefit in 2010. In January 2011, the IRS appealed the Tax Court's decision to the U.S. Court of Appeals for the Third Circuit (Third Circuit). In December 2011, the Third Circuit issued its opinion reversing the Tax Court's decision, holding that the U.K. WPT is not a creditable tax. As a result of the Third Circuit's adverse determination, PPL recorded a $39 million expense in the fourth quarter of 2011. In February 2012, PPL filed a petition for rehearing of the Third Circuit's opinion. In March 2012, the Third Circuit denied PPL's petition. In June 2012, the U.S. Court of Appeals for the Fifth Circuit issued a contrary opinion in an identical case involving another company. In July 2012, PPL filed a petition for a writ of certiorari seeking U.S. Supreme Court review of the Third Circuit's opinion.
