Schedule of inputs used in measurement of CGU
The key assumptions used in the estimation of value in use of each CGU as of December 31, 2019 are as follows.

Display (AD PO)(*3)

(*1)
The discount rate was calculated using the weighted average cost of equity capital and debt, and the beta of equity capital was calculated as the average of five global listed companies in the same industry and the Group. Cost of debt was calculated by the interest rate of the Group’s publicly issued bonds and debt ratio was determined using the average of the debt ratios of the five global listed companies in the same industry
with
 the Group.
(*2)
As a result of impairment test, the carrying amount of Lighting CGU which produces OLED lighting products was fully impaired with impairment loss of
W
230,867 million recognized as other expenses for the year ended December 31, 2019.
(*3)
As a result of impairment test, the carrying amount of Display(AD PO) CGU which produces plastic OLED mobile products and commenced mass production in 2019, exceeds the recoverable amount of
W
1,729,209 million and an impairment loss of
W
1,395,655 million was recognized as other expenses for the year ended December 31, 2019. The value in use determined for this CGU is sensitive to the discount rate
and terminal growth rate
used in the discounted cash flow model. If the discount rate increases by 0.5%, the value in use would have decreased by
W
259,221 million (15.0%). If the terminal growth rate decreases by 0.5%, the value in use would have decreased by
W
169,626 million (9.8%).
(*4)
As a result of impairment test for Display CGU, the recoverable amount exceeds the carrying amount by
W
3,568,588 million. The value in use determined for this CGU is sensitive to the discount rate and terminal growth rate used in the discounted cash flow model.
