Goodwill and Intangible Assets Disclosure [Abstract] |
Goodwill and Other Intangible Assets | 14. Goodwill and Other Intangible Assets (PPL) The change in the carrying amount of goodwill for the three months ended March 31, 2017 was due to the effect of foreign currency exchange rates on the U.K. Regulated segment. The change in the carrying amount of other intangible assets for the three months ended March 31, 2017 was primarily due to a change in WPD’s approach in acquiring rights-of-way relating to WPD equipment impacting landowners' property. A shorter term agreement at a lower cost is now being offered which has also reduced the estimated liability for claims not yet settled.
