(1)

Cash and cash equivalents, notes and accounts receivable (including related parties), other receivables and refundable deposits were classified as loans and receivables under IAS 39 are now classified at amortized cost with assessment of future 12-month or lifetime expected credit loss under IFRS 9. As a result of retrospective application, the adjustments for accounts receivable would result in a decrease in loss of allowance of NT$244.8 million and an increase in retained earnings of NT$244.8 million on January 1, 2018.

(2)

As equity investments that were previously classified as available-for-sale financial assets under IAS 39 are not held for trading, the Company elected to designate all of these investments as at FVTOCI under IFRS 9. As a result, the related other equity-unrealized gain/loss on available-for-sale financial assets of NT$228.3 million is reclassified to increase other equity - unrealized gain/loss on financial assets at FVTOCI.

As equity investments previously measured at cost under IAS 39 are remeasured at fair value under IFRS 9, the adjustments would result in an increase in financial assets at FVTOCI of NT$967.1 million, an increase in other equity-unrealized gain/loss on financial assets at FVTOCI of NT$968.7 million and a decrease in non-controlling interests of NT$1.6 million on January 1, 2018.

For those equity investments previously classified as available-for-sale financial assets under IAS 39, the impairment losses that the Company had recognized have been accumulated in retained earnings. Since these investments were designated as at FVTOCI under IFRS 9 and no impairment assessment is required, the adjustments would result in a decrease in other equity - unrealized gain/loss on financial assets at FVTOCI of NT$1,294.6 million and an increase in retained earnings of NT$1,294.6 million on January 1, 2018.

(3)

Debt investments were previously classified as available-for-sale financial assets under IAS 39. Under IFRS 9, except for debt instruments of NT$779.5 million whose contractual cash flows are not solely payments of principal and interest on the principal outstanding and therefore are classified as at FVTPL with the related other equity-unrealized gain/loss on available-for-sale financial assets of NT$10.1 million being consequently reclassified to decrease retained earnings, the remaining debt investments are classified as at FVTOCI with assessment of future 12-month expected credit loss because these investments are held within a business model whose objective is both to collect the contractual cash flows and sell the financial assets. The related other equity-unrealized gain/loss on available-for-sale financial assets of NT$434.4 million is reclassified to decrease other equity-unrealized gain/loss on financial assets at FVTOCI. As a result of retrospective application of future 12-month expected credit loss, the adjustments would result in an increase in other equity - unrealized gain/loss on financial assets at FVTOCI of NT$30.7 million and a decrease in retained earnings of NT$30.7 million on January 1, 2018.

(4)

Debt investments previously classified as held-to-maturity financial assets and measured at amortized cost under IAS 39 are classified as measured at amortized cost with assessment of future 12-month expected credit loss under IFRS 9 because the contractual cash flows are solely payments of principal and interest on the principal outstanding and these investments are held within a business model whose objective is to collect the contractual cash flows. As a result of retrospective application of future 12-month expected credit loss, the adjustments would result in an increase in loss allowance of NT$8.3 million and a decrease in retained earnings of NT$8.3 million on January 1, 2018.

(5)

With the retrospective adoption of IFRS 9 by associates accounted for using equity method, the corresponding adjustments made by the Company would result in an increase in investments accounted for using equity method of NT$8.3 million, a decrease in other equity- unrealized gain/loss on financial assets at FVTOCI of NT$23.6 million, a decrease in other equity- unrealized gain/loss on available-for-sale financial assets of NT$2.1 million and an increase in retained earnings of NT$34.0 million on January 1, 2018.
