Foreign currency risk
More than 90% of the Companys revenue is denominated in U.S. dollar and over
one-half
of its capital expenditures are denominated in currencies other than NT dollar, primarily in U.S. dollar, Japanese yen and Euro. As a result, any significant fluctuations to its disadvantage in
exchanges rate of NT dollar against such currencies, in particular a weakening of U.S. dollar against NT dollar, would have an adverse impact on the revenue and operating profit as expressed in NT dollar. The Company uses foreign currency derivative
contracts, such as currency forwards or currency swaps, to protect against currency exchange rate risks associated with
non-NT
dollar-denominated assets and liabilities and certain forecasted transactions. The
Company utilizes U.S. dollar denominated debt to partially offset currency risk arising from U.S. dollar denominated receivables for balance sheet hedges. These hedges reduce, but do not entirely eliminate, the financial impact on the Company caused
by the effect of foreign currency exchange rate movements on the assets and liabilities.
Based on a sensitivity analysis
performed on the Companys total monetary assets and liabilities for the six months ended June 30, 2019 and 2018, a hypothetical adverse foreign currency exchange rate change of 10% would have decreased its net income by
NT$849,695 thousand and NT$261,642 thousand, respectively, and decreased its other comprehensive income by NT$158,511 thousand and NT$356,200 thousand, respectively, after taking into account hedges and offsetting positions.
Interest rate risk
The Company is exposed to interest rate risk primarily related to its investments in fixed income securities and outstanding
debt.
Financial assets at amortized costs are measured at amortized cost, and therefore changes in interest rates would
not affect the fair value. On the other hand, financial assets at FVTPL and financial assets at FVTOCI are exposed to fair value fluctuations caused by changes in interest rates. The Company entered into interest rate futures to partially hedge the
interest rate risk on its financial assets at FVTPL and financial assets at FVTOCI. These hedges can offset only a small portion of the financial impact from movements in interest rates.
Based on a sensitivity analysis performed on fixed income investments at the end of the reporting period, interest rate
increase of 100 basis points (1.00%) across all maturities would have decreased the fair value by NT$2,693,155 thousand and NT$2,409,566 thousand for the six months ended June 30, 2019 and 2018, respectively. The decreases were composed of
NT$3,036,106 thousand decrease and NT$2,280,513 thousand decrease in other comprehensive income, and NT$342,951 thousand increase and NT$129,053 thousand decrease in net income for the six months ended June 30, 2019 and 2018, respectively.
All of the Companys long-term debts are fixed-rate, NT dollar denominated bonds and measured at amortized cost. As
such, changes in interest rates would not affect the future cash flows and fair value.
Other price risk
The Company is exposed to equity price risk arising from financial assets at FVTOCI.
Assuming a hypothetical decrease of 10% in prices of the equity investments at the end of the reporting period for the six
months ended June 30, 2019 and 2018, the other comprehensive income would have decreased by NT$414,268 thousand and NT$707,088 thousand, respectively.

Credit risk management
|
Credit risk refers to the risk that a counterparty will default on its contractual obligations resulting in financial losses
to the Company. The Company is exposed to credit risks from operating activities, primarily trade receivables, and from investing activities, primarily deposits, fixed-income investments and other financial instruments with banks. Credit risk is
managed separately for business related and financial related exposures. As of the end of the reporting period, the Companys maximum credit risk exposure is equal to the carrying amount of financial assets.
