(a)       Includes unrealized gains and losses from economic activity. See Note 19 for additional information.

(b)       See Note 1for additional information on Utility Revenue.

(c)       See "PLR Contracts/Purchase of Accounts Receivable" and "NUG Purchases" in Note 16 for a discussion of the basis of accounting between reportable segments.

(d)       Represents non-cash expense items that include amortization of nuclear fuel, regulatory assets, debt discounts and premiums,debt issuance costs, emission allowances and RECs.

(e)       Includes interest income from affiliate(s).

(f)       Includes interest expense with affiliate(s).

(g)       Represents both current and deferred income taxes, including investment tax credits.

(h)       Represents a non-cash expense item that is also included in “Income Taxes.”

(i)       For PPL Energy Supply, 2010 and 2009 were reported as Discontinued Operations. See Note 9 for additional information, including the $24 million of income tax expense recognized in 2009 by the International Regulated segment related to a correction of income tax bases for the Latin American businesses sold in 2007.

(j)       In April 2011, during the PPL Susquehanna Unit 2 refueling and generation uprate outages, a planned inspection of the Unit 2 turbine revealed cracks in certain of its low pressure turbine blades. As a precaution, PPL Susquehanna also took Unit 1 out of service in mid-May to inspect that unit's turbine blades. This inspection revealed cracked blades similar to those found in Unit 2. Replacement of these blades was completed, significantly extending these outages. The after-tax earnings impact, including reduced energy sales margins and repair expense for both units was $63 million in 2011.

(k)       A portion of the goodwill related to the 2010 LKE acquisition has been attributed to PPL's Supply segment.
