Allocating goodwill to cash-generating units

The Group did not monitor goodwill for internal management purpose but for financial reporting purpose and, therefore, the goodwill was allocated to the following cash-generating units for evaluation of impairment: packaging segment, testing segment, EMS segment and other segment. The carrying amounts of goodwill allocated to cash-generating units were as follows:


	December 31
	2023		2024
	(Retrospectively Adjusted)
Cash-generating units	NT$		NT$		US$ (Note 4)

Packaging segment	$	35,426,817	$	35,437,523	$	1,080,742
Testing segment		13,414,094		13,489,766		411,399
EMS segment		3,430,415		3,449,952		105,214
Others		148,101		148,101		4,516


	$	52,419,427	$	52,525,342	$	1,601,871

Impairment assessment

At the end of each year, the Group performs evaluation of goodwill for impairment by reviewing the recoverable amounts based on value in use which incorporates cash flow projections estimated by management covering a five-year period. The cash flows beyond that five-year period are extrapolated using a steady per annum growth rate. In assessing value in use, the estimated future cash flows are discounted to their present value using annual pre-tax discount rates which were 8.65%-14.64%, 13.83%-14.08% and 13.91%-14.56% as of December 31, 2022, 2023 and 2024, respectively. For the years ended December 31, 2022, 2023 and 2024,

impairment loss was recognized. The key assumption used in calculating each segment’s value in use also included the growth rates for operating revenues, which were based on the forecast for the Group and the industry as well as the Group’s historical performance.

Management believes that any reasonably possible change in the key assumptions on which the recoverable amount was based on would not cause the carrying amount of each cash-generating unit to exceed its recoverable amount.
