pre_text: Other identifiable intangible assets were as follows: Non-amortizing intangible assets are comprised of brands and trademarks. Amortizing intangible assets, carrying a remaining weighted-average life of approximately 20 years, are principally composed of customer relationships, and acquired intellectual property. For fiscal 2019, 2018, and 2017, we recognized amortization expense of $49.1 million, $34.9 million, and $33.6 million, respectively. Based on amortizing assets recognized in our Consolidated Balance Sheet as of May 26, 2019, amortization expense is estimated to average $58.3 million for each of the next five years, with a high expense of $59.9 million in fiscal 2020 and decreasing to a low expense of $54.2 million in fiscal 2024. During fiscal 2019, in conjunction with the divestiture of our Italian-based frozen pasta business, Gelit, we reclassified $15.1 million and $1.7 million of goodwill and other identifiable intangible assets, respectively, to noncurrent assets held for sale for periods prior to the divestiture. During fiscal 2019, as a result of our annual impairment test for indefinite lived intangibles, we recognized impairment charges of $76.5 million for our Chef Boyardee® and Red Fork® brands in our Grocery & Snacks segment. We also recognized impairment charges of $13.1 million for our Aylmer® and Sundrop ® brands in our International segment. During fiscal 2018, as a result of our annual impairment test for indefinite lived intangibles, we recognized impairment charges of $4.0 million for our HK Anderson® , Red Fork® , and Salpica® brands in our Grocery & Snacks segment. We also recognized an impairment charge of $0.8 million for our Aylmer® brand in our International segment. During fiscal 2017, we recorded goodwill impairment charges in our International reporting segment totaling $198.9 million, of which $139.2 million related to our Canadian reporting unit and $59.7 million related to our Mexican reporting unit. These impairment charges resulted from a change in reporting segments, which occurred in the first quarter of fiscal 2017 when we were required to determine new reporting units at a lower level, and from further deterioration in forecasted sales and profits during fiscal 2017, which were caused primarily by changes in foreign exchange rates. In fiscal 2017, due to declining sales of certain brands, we elected to perform a quantitative impairment test for indefinite lived intangibles of those brands. During fiscal 2017, we recognized impairment charges of $31.5 million for our Del Monte® brand and $5.5 million for our Aylmer® brand in our International segment. We also recognized impairment charges of $67.1 million for our Chef Boyardee® brand and $1.1 million for our Fiddle Faddle® brand in our Grocery & Snacks segment.
