(a) | During the second quarter of 2019, LKE recorded a deferred income tax benefit associated with two projects placed into service that prepare a generation waste material for reuse and, as a result, qualify for a Kentucky recycling credit. The applicable credit provides tax benefits for a portion of the equipment costs for major recycling projects in Kentucky, with the benefit recognized during the period in which the assets are placed into service. A valuation allowance of $3 million has been recognized related to this credit due to insufficient Kentucky taxable income projected at LKE. During the third quarter of 2019, LKE filed the Kentucky recycling credit application with the Kentucky Department of Revenue and expects a ruling in the fourth quarter of 2019.
(b) | During the second quarter of 2018, LKE recorded deferred income tax expense, primarily associated with LKE's non-regulated entities, due to the Kentucky corporate income tax rate reduction from 6% to 5%, as enacted by HB 487, effective January 1, 2018.

Other U.S. Tax Reform (All Registrants) The IRS issued proposed regulations for certain provisions of the TCJA in 2018, including interest deductibility and Global Intangible Low-Taxed Income (GILTI). In June 2019, the IRS issued both final and new proposed regulations relating to GILTI. PPL has determined that neither these final nor proposed regulations materially change PPL's current interpretation of the statutory impact of these rules on the Registrants. Proposed regulations relating to the limitation on the deductibility of interest expense were issued in November 2018 and such regulations provide detailed rules implementing the broader statutory provisions. These proposed regulations should not apply to the Registrants until the year in which the regulations are issued in final form, which is expected to be in the fourth quarter of 2019. It is uncertain what form the final regulations will take and, therefore, the Registrants cannot predict what impact the final regulations will have on the tax deductibility of interest expense. However, if the proposed regulations were issued as final in their current form, the Registrants could have a limitation on a portion of their interest expense deduction for tax purposes and such limitation could be significant. PPL expressed its views on these proposed regulations in a comment letter addressed to the IRS on February 26, 2019.
