Goodwill And Other Intangibles [Abstract]

(6) Goodwill and Other Intangibles:

We are required to perform impairment tests related to our goodwill annually, which we perform as of December 31, or sooner if an indicator of impairment occurs. Goodwill, net of $3,429 million in accumulated goodwill impairments, was $6,383 million as of March 31, 2019 and December 31, 2018. During the first quarter of 2019, Frontier did not identify any triggering events that would indicate impairment of goodwill, or any other intangible assets.
