 8. Asset Impairment Charges Asset impairment charges incurred during the year ended December 31, 2019 were primarily the result of impairing the remaining NantHealth acquired customer relationship intangible balance of $8.1 million. We also recognized non-cash impairment charges of $2.7 million on the retirement of certain hosting assets due to data center migrations. Impairment of long-term investments during the year ended December 31, 2019 consisted of an impairment of $1.7 million associated with one of our long-term equity investments. We also recovered $1.0 million from one of our long-term equity investments investment that we had previously impaired. We also recorded a goodwill impairment charge of $25.7 million related to our HHS reporting unit. Refer to Note 7, “Goodwill and Intangible Assets” for further information regarding this impairment. We incurred several non-cash asset impairment charges during the year ended December 31, 2018. We recorded non-cash asset impairment charges of $33.2 million related to the write-off of capitalized software as a result of our decision to discontinue several software development projects. We also recorded $22.9 million of non-cash asset impairment charges related to our acquisition of the patient/provider engagement solutions business from NantHealth in 2017, which included the write-downs of $2.2 million of acquired technology and $20.7 million, representing the unamortized value assigned to the modification of our existing commercial agreement with NantHealth, as we no longer expect to recover the value assigned to these assets. The remaining $2.1 million of non-cash asset impairment charges recorded during the year ended December 31, 2018 relate to the disposal of fixed assets as a result of relocating and consolidating business functions and locations from recent acquisitions. We recorded a goodwill impairment charge of $13.5 million related to NantHealth during the year ended December 31, 2018.

We recognized non-cash impairment charges of $15.5 million in 2018 related to two of our cost-method equity investments and a related note receivable. These charges equaled the cost bases of the investments and the related note receivable prior to the impairment. We recorded non-cash charges of $165.3 million during the year ended December 31, 2017, including impairment charges of $144.6 million associated with two of the Company’s long-term investments based on management’s assessment of the likelihood of near-term recovery of the investments’ value.

Question: If Asset impairment charges in 2019 were 60,000 thousands, what would be the change from 2018 to 2019? (in thousand)

Python solution:
def solution():
    # Define variables name and value
    asset_impairment_2019 = 60000
    asset_impairment_2018 = 58166
    
    # Do math calculation to get the answer
    answer = asset_impairment_2019 - asset_impairment_2018
    
    return answer

Answer: 1834
