Goodwill and Intangible Assets Disclosure [Abstract]

Goodwill and indefinite lived trademarks are not amortized but are tested for impairment at least annually, in accordance with the provisions of ASC Topic 350-20-35-1. Goodwill impairment is deemed to exist if the net book value of a reporting unit exceeds its estimated fair value. The fair value of a reporting unit is determined using a discounted cash flow methodology. The Company’s reporting units are determined based upon whether discrete financial information is available and reviewed regularly, whether those units constitute a business, and the extent of economic similarities between those reporting units for purposes of aggregation. The Company’s reporting units identified under ASC Topic 350-20-35-33 are at the component level, or one level below the operating segment level as defined under ASC Topic 280-10-50-10 “Segment Reporting - Disclosure.” The Company has two reporting units as of December 31, 2019 and March 31, 2019. The Duff-Norton reporting unit (which designs, manufactures and sources mechanical and electromechanical actuators and rotary unions) had goodwill of $9,611,000 at December 31, 2019 and March 31, 2019 and the Rest of Products reporting unit (representing the hoist, chain, forgings, digital power, motion control, manufacturing, and distribution businesses) had goodwill of $313,155,000 and $313,205,000 at December 31, 2019 and March 31, 2019, respectively.

Refer to the 2019 10-K for information regarding our annual goodwill and indefinite lived trademark impairment evaluation. Future impairment indicators, such as declines in forecasted cash flows, may cause impairment charges. Impairment charges could be based on such factors as the Company’s stock price, forecasted cash flows, assumptions used, control premiums or other variables. There were no such indicators during the quarter ended December 31, 2019.

Identifiable intangible assets acquired in a business combination are amortized over their estimated useful lives. Identifiable intangible assets are summarized as follows (in thousands):

The Company’s intangible assets that are considered to have finite lives are amortized. The weighted-average amortization periods are 15 years for trademarks, 18 years for customer relationships, 18 years for acquired technology, 6 years for other, and 18 years in total. Trademarks with a carrying value of $46,971,000 as of December 31, 2019 have an indefinite useful life and are therefore not being amortized.

Total amortization expense was $3,229,000 and $3,701,000 for the three month periods ended December 31, 2019 and 2018, respectively. Total amortization expense was $9,708,000 and $11,358,000 for the nine month periods ended December 31, 2019 and 2018, respectively. Based on the current amount of identifiable intangible assets and current exchange rates, the estimated annual amortization expense is approximately $13,000,000 for fiscal years 2020 through 2024.
