Based on the future operation plans and the capacity evaluation, the Group assessed that a portion of plant and equipment in the packaging segment and the testing segment were not qualified for the production needs and, therefore, recognized an impairment loss of NT$201,006 thousand, NT$992,273 thousand and NT$126,766 thousand (US$4,571 thousand) under the line item of other operating income and expenses (Note 25) for the years ended December 31, 2019, 2020 and 2021, respectively.
The recoverable amounts of a portion of the impaired plant and equipment were determined by their fair value less cost of disposal, of which the fair value was based on the recent quoted prices of assets with similar age and obsolescence provided by vendors in secondary market or the disposal price, and both of which represented Level 3 inputs because the secondary market was not active and the disposal price was negotiated with counterparties. The recoverable amounts of the remaining impaired plant and equipment were determined by their value in use and the Group expects only short-term or no economic benefits would be generated by these assets and the discount effect was immaterial.
Each class of property, plant and equipment was depreciated on a straight-line basis over the following useful lives:
 
Buildings and improvements
         
Main plant buildings
      10-55 years  
Cleanrooms
     
10-20 years
  
Others
     
3-20 years
  
Machinery and equipment
     
2-10 years
  
Other equipment
      2-20 years  
The capitalized borrowing costs for the years ended December 31, 2019, 2020 and 2021 are disclosed in Note 25.
