The sensitivity analysis above is conducted for monetary assets and liabilities denominated in foreign currencies other than functional currency, without consideration of hedge effect of related derivatives, as of December 31, 2020 and 2021. To manage its foreign currency risk related to foreign currency denominated receivables and payables, the Company has a policy to enter into currency forward agreements. In addition, to manage its foreign currency risk related to foreign currency denominated expected sales transactions and purchase transactions, the Company enters into currency forward agreements. There is an economic relationship between the hedged item and the hedging instrument as the terms of cross-currency swap agreement is consistent with the terms of expected transaction (repayment of foreign debt securities and others). The hedging ratio is 1:1 as the risk of cross-currency swap agreement matches the hedged instrument. As of December 31, 2021, the hedging instrument (cross-currency swap) hedges the risk of the hedged item (repayment of foreign debt securities and others).
| ② | Interest rate risk
The Company is exposed to interest rate risk due to its borrowing with floating interest rates. A 1% increase or decrease is used when reporting interest rate risk internally to key management personnel and represents management’s assessment of the reasonably possible change in interest rates. The Company’s borrowings and debt securities with floating interest rates as of December 31, 2020 and 2021 are as follows:

| (*) | The effect on the shareholders’ equity excluding the impact of income taxes.
The Company manages its interest rate risk by having a balanced portfolio of fixed and variable rate loans and borrowings. To manage this, the Company enters into interest rate swaps, in which it agrees to exchange, at specified intervals, the difference between fixed and variable rate interest amounts calculated by reference to an agreed-upon notional principal amount. The above analysis measures the interest rate risk before reflecting the hedge effect by related derivatives.
| ③ | Electricity rates risk
Following the approval of the Ministry of Trade, Industry and Energy (MOTIE) on December 17, 2020, the Company has adopted a new pricing system, “the cost pass-through tariff system”, beginning January 1, 2021. Under the cost pass-through system, the electricity rates are not predetermined at fixed rates but change upon approval by the MOTIE under Electric Utility Act of the Republic of Korea. The Company is exposed to electricity rates risk due to changes in government regulations and policies on national power supply schemes and electricity billing rates, in consideration of the national economy. A sensitivity analysis on the Company’s income for the period assuming a 1% increase and decrease in price of electricity for the years ended December 31, 2020 and 2021 is as follows:

| (iv) | Liquidity risk
The Company has established an appropriate liquidity risk management framework for the management of the Company’s short, medium and long-term funding and liquidity management requirements. The Company manages liquidity risk by continuously monitoring forecasted and actual cash flows, and by matching the maturity profiles of financial assets and liabilities. In addition, the Company has established credit lines on its trade financing and bank overdrafts, and through payment guarantees it has received, it maintains an adequate credit (borrowing) line. In addition, the Company has the ability to utilize excess cash or long-term borrowings for major construction investments.

(3) | Fair value risk
The fair value of the Company’s actively-traded financial instruments (i.e., FVTPL, FVOCI, etc.) is based on the traded market-price as of the reporting period end. The fair value of the Company’s financial assets is the amount which the asset could be exchanged for or the amount a liability could be settled for. The fair values of financial instruments where no active market exists or where quoted prices are not otherwise available are determined by using valuation techniques. Valuation techniques include using recent arm’s length market transactions between knowledgeable, willing parties, if available, reference to the current fair value of another instrument that is substantially the same, discounted cash flow analysis and option pricing models. If there is a valuation technique commonly used by market participants to price the instrument and that technique has been demonstrated to provide reliable estimates of prices obtained in actual market transactions, the Company uses that technique. For trade receivables and payables, the Company considers the carrying value net of impairment as fair value. While for disclosure purposes, the fair value of financial liabilities is estimated by discounting the future contractual cash flows based on current market interest rates applied to similar financial instruments.

| (ii) | Interest rates used for determining fair value
The interest rates used to discount estimated cash flows, when applicable, are based on the government yield curve at the reporting date plus an adequate credit spread. The discount rates used for calculating fair value as of December 31, 2020 and 2021 are as follows:
Type |  | 2020 |  |  | 2021 |
Derivatives |  |  | (-) 0.73% ~ 3.08% |  |  |  | (-) 0.63% ~ 3.88% |
Borrowings and debt securities |  |  | (-) 0.53% ~ 4.38% |  |  |  | (-) 0.30% ~ 4.38% |
Finance lease |  |  | 0.57% ~ 16.60% |  |  |  | 0.00% ~ 16.83% |
| (iii) | Fair value hierarchy
The following table provides an analysis of financial instruments that are measured subsequent to initial recognition at fair value, classified as Level 1, 2 or 3, based on the degree to which the fair value is observable. Level 1: Unadjusted quoted prices in active markets for identical assets or liabilities; Level 2: Inputs other than quoted prices that are observable for the asset or liability either directly or indirectly; and Level 3: Inputs that are not based on observable market data. Fair values of financial instruments by hierarchy level as of December 31, 2020 and 2021 are as follows:

The fair value of financial assets (FVTPL and FVOCI) publicly traded is measured at the closing bid price quoted at the end of the reporting period. Meanwhile, the fair value of unquoted financial assets (FVTPL and FVOCI) is accounted for using the valuation results of external valuation services in which weighted average borrowing rates of interest of evaluated companies are used as the discount rates. The fair value of derivatives is measured using the discounted cash flow (DCM) model reflecting key input factors such as credit risks, interest rates and exchange rates. Changes of financial assets and liabilities which are classified as level 3 for the years ended December 31, 2020 and 2021 are as follows:
