Goodwill and indefinite-lived intangible assets, primarily trade names, are not amortized and are subject to assessment for impairment by applying a fair-value based test on an annual basis or more frequently if circumstances indicate a potential impairment. Our annual assessment date is October 1. There were no impairment charges recorded in the three and nine months ended September 30, 2019 and 2018. There were no accumulated impairment losses recorded as of September 30, 2019. The table below summarizes the goodwill balances for continuing operations by reportable segment and Corporate and Other Operations:

For the existing intangible assets, we anticipate amortization expense for the remainder of 2019 and each of the next five years of $6 million, $24 million, $22 million, $20 million, $17 million and $12 million, respectively. These amounts exclude the

intangible assets acquired in connection with the European pest control acquisitions completed during the three months ended September 30, 2019, as intangible asset values and the related useful lives have not yet been finalized.
