The balances in the “effect on profit or loss” column consider the interim effects of the contracts in force As of December 31, 2017, 2016 and 2015.

Derivative contract maturities are detailed as follows:

Series	Contract amount		Currency	Maturity date
	ThUS$
H		191,638	UF	01/05/2018
O		58,748	UF	02/01/2022

The Company uses cross currency swap derivative instruments to hedge the possible financial risk associated with the volatility of the exchange rate associated with Chilean pesos and UF. The objective is to hedge the exchange rate financial risks associated with bonds payable. Hedges are documented and tested to measure their effectiveness.

Based on a comparison of critical terms, hedging is highly effective, given that the hedged amount is consistent with obligations maintained for bonds denominated in Chilean pesos and UF. Likewise, hedging contracts are denominated in the same currencies and have the same expiration dates of bond principal and interest payments.

Hedge Accounting

The Company classifies derivative instruments as hedging that may include derivative or embedded derivatives either as fair value hedge derivative instruments, cash flow hedge derivative instruments, or hedge derivative instruments for net investment in a business abroad.

a) Fair value hedge

Changes in fair values of derivative instruments classified as fair value hedge derivative instruments are accounted for in gains and losses immediately along with any change in the fair value of the hedged item that is attributable to the risk being hedged.

The Company documents the relationship between hedge instruments and the hedged item along with the objectives of its risk management and strategy to carry out different hedging transactions. In addition, upon commencement of the period hedged and then on a quarterly basis, the Company documents whether hedge instruments have been efficient and met the objective of hedging market fluctuations. For this purpose, we use the effectiveness test. A hedge instrument is deemed effective if the effectiveness test result is between 80% and 125%.

The hedge instruments are classified as effective or not effective on the basis of the effectiveness test results. At present, hedges are classified as effective on the basis of the effectiveness tests. This note includes the detail of fair values of derivatives classified as hedging instruments.

b) Cash flow hedges

Cash flow hedges cover exposure to the cash flow variations attributable to a risk associated with a specific transaction that is very likely to be executed, which may have material effects on the results of the Company.

10.8

Fair value measurement of assets and liabilities

Financial assets and liabilities measured at fair value consist of Options and Forwards hedging the mismatch in the balance sheet and cash flows, Cross Currency Swaps (CCS) to hedge bonds issued in local currency ($/UF), and Interest Rate Swaps (IRS) to hedge LIBOR rate debt issued.

The value of the Company’s assets and liabilities recognized by CCS contracts is calculated as the difference between the present value of discounted cash flows of the asset (pesos/UF) and liability (US$) parts of the derivative. In the case of the IRS, the asset value recognized is calculated as the difference between the discounted cash flows of the asset (variable rate) and liability (fixed rate) parts of the derivative. Forwards: Are calculated as the difference between the strike price of the contract and the spot price plus the forwards points at the date of the contract. Options: The value recognized is calculated using the Black-Scholes method.

In the case of CCS, the entry data used for the valuation models are UF, peso,USD and basis swap rates. In the case of fair value calculations for IRS, the FRA (Forward Rate Agreement) rate and ICVS 23 Curve (Bloomberg: cash/deposits rates, futures, swaps). In the case of forwards, the forwards curve for the currency in question is used. Finally, with options, the spot price, risk-free rate and volatility of exchange rate are used, all in accordance with the currencies used in each valuation. The financial information used as entry data for the Company’s valuation models is obtained from Bloomberg, the well-known financial software company. Conversely, the fair value provided by the counterparties of derivatives contracts is used only as a control and not for valuation.

The effects on profit or loss of movements in these amounts may be recognized in the caption Finance costs, foreign currency translation gain (loss) or cash flow hedges in the statement of comprehensive income, depending on each particular case.

The fair value measurement of debt is only performed to determine the present market value of secured and unsecured long-term obligations; bonds denominated in local currency (Ch$/UF) and foreign currency (US$), credits denominated in foreign currency (US$), which is classified under Level 2 in the fair value hierarchy established by IFRS.

The value of the Company’s reported liabilities is calculated as the present value of discounted cash flows at market rates at the time of valuation, taking into account the maturity date and exchange rate. The entry data used for the model includes the UF and peso rates, which are obtained using Bloomberg, the well-known financial software company and the ‘Asociación de Bancos e Instituciones Financieras’ (ABIF) (Association of Banks and Financial Institutions’).

Fair value hierarchy

The fair value hierarchy is detailed as follows:

Level 1: using quoted prices (unadjusted) only in active markets.

Level 2: when in any phase in the valuation process inputs other than quoted prices have been used in Level 1 that are observable directly in markets.

Level 3: inputs for the asset or liability that are not based on observable market data.

The valuation technique used for determining fair value of our hedging instruments is that indicated in Level 2.

Estimated fair value of financial instruments and financial derivatives

As required by IFRS 7, the following information is presented for the disclosure of the estimated fair value of financial assets and liabilities.

Although inputs represent Management's best estimate, they are subjective and involve significant estimates related to the current economic and market conditions, as well as risk features.

Methodologies and assumptions used depend on the risk terms and characteristics of instruments and include the following as a summary:

-	Cash equivalent approximates fair value due to the short-term maturities of these instruments.

-	The fair value of trade receivables, current is considered to be equal to the carrying amount due to the maturity of such accounts at short-term.

-	The fair value of other current financial liabilities is considered to be equal to their carrying values.

-	For interest-bearing liabilities with original maturity of more than a year, fair values are calculated by discounting contractual cash flows at their original current market rates with similar terms.

-	The fair value of debt is considered in Level 2.

-	For forward and swap contracts, fair value is determined using quoted market prices of financial instruments with similar characteristics.

The detail of the Company’s instruments at carrying value and estimated fair value is as follows:
