Independent Auditors’ Report

To the Board of Directors of AU Optronics Corp.:

Opinion

We have audited the consolidated financial statements of AU Optronics Corp. and its subsidiaries (“the Company”), which comprise the consolidated balance sheets as of December 31, 2017 and 2016, the consolidated statement of comprehensive income, consolidated statement of changes in equity, and consolidated statement of cash flows for the years ended December 31, 2017 and 2016, and notes to the consolidated financial statements including a summary of significant accounting policies.

In our opinion, the accompanying consolidated financial statements present fairly, in all material respects, the consolidated financial position of the Company as of December 31, 2017 and 2016, and its consolidated financial performance and its consolidated cash flows for each of the years then ended, in accordance with the Regulations Governing the Preparation of Financial Reports by Securities Issuers and with the International Financial Reporting Standards, International Accounting Standards, interpretation as well as related guidance endorsed by the Financial Supervisory Commission of the Republic of China.

Basis for Opinion

We conducted our audit in accordance with the Regulations Governing Auditing and Certification of Financial Statements by Certified Public Accountants and the auditing standards generally accepted in the Republic of China. Our responsibilities under those standards are further described in the Auditor’s Responsibilities for the Audit of the Consolidated Financial Statements section of our report. We are independent of the Company in accordance with the Certified Public Accountants Code of Professional Ethics in Republic of China (“the Code”), and we have fulfilled our other ethical responsibilities in accordance with the Code. We believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our opinion.

Key Audit Matters

Key audit matters are those matters that, in our professional judgment, were of most significance in our audit of the consolidated financial statements of the current period. These matters were addressed in the context of our audit of the consolidated financial statements as a whole, and in forming our opinion thereon, and we do not provide a separate opinion on these matters.

Impairment of long-term non-financial assets (including goodwill)

Refer to Note 4(17) “Impairment – non-financial assets”, Note 5(2) and Note 5(3) “Critical accounting judgments and key sources of estimation and assumption uncertainty”, Note 6(11) “Property, plant and equipment”, and Note 6(13) “Intangible assets” to the consolidated financial statements.

Description of key audit matter:

The Company operates in an industry with high investment costs, has goodwill through the acquisition of subsidiaries, and may experience volatility in response to changes in the external market; hence, it is important to assess the impairment of its long-term non-financial assets (including goodwill). The impairment assessment includes identifying cash-generating units, determining a valuation model, determining significant assumptions, and computing recoverable amounts. With the complexity of the impairment assessment process and the involvement of significant management judgment regarding assumptions used, this is one of the key areas our audit focused on.

3

How the matter was addressed in our audit:

In relation to the key audit matter above, our principal audit procedures included understanding and testing the Company’s controls surrounding the impairment assessment and testing process; assessing whether there are impairment indications for the identified cash-generating units of the Company and its related assets; understanding and assessing the appropriateness of the valuation model used by the management in the impairment assessment and the significant assumptions used to determine related assets’ future cash flows projection, useful lives, and weighted-average cost of capital; retrospectively reviewing the accuracy of assumptions used in prior-period estimates and performing a sensitivity analysis of key assumptions and results; in addition to the above audit procedures, appointing specialists to evaluate the appropriateness of the weighted-average cost of capital used and related assumptions; performing an inquiry of the management and identifying any event after the balance sheet date if able to affect the results of the impairment assessment; and assessing the adequacy of the Company’s disclosures of its policy on impairment of noncurrent non-financial assets and other related disclosures.

Recognition of deferred tax assets

Refer to Note 4(22) “Income taxes”, Note 5(5) “Critical accounting judgments and key sources of estimation and assumption uncertainty”, and Note 6(28) “Income taxes” to the consolidated financial statements.

Description of key audit matter:

The recognition of deferred tax assets for the related unused tax losses, unused tax credits, and deductible temporary differences arising from operating entities located in other areas is based on management estimates of its future available taxable profits and the probability that the related deferred tax assets will be realized. This is one of the key areas our audit focused on.

How the matter was addressed in our audit:

In relation to the key audit matter above, our principal audit procedures included understanding and testing the controls surrounding the Company’s assessment process for recognition of deferred tax assets; understanding the Company’s significant operating entities for which deferred tax assets are recognized and assessing the management estimates for assumptions used in the future cash flow projection and future taxable profits calculation; retrospectively reviewing the accuracy of assumptions used in prior-period estimates of future cash flow projection and assessing whether there are any other matters that will affect the recognition of deferred tax assets; and assessing the adequacy of the Company’s disclosures regarding its deferred tax asset recognition policy and other related disclosures.

Revenue recognition

Refer to Note 4(19) “Revenue recognition”, and Note 6(22) “Revenue” to the consolidated financial statements.

Description of key audit matter:

Revenue is recognized when the risks and rewards specified in each individual contract with customers are transferred. The Company recognizes revenue depending on the various sales terms in each individual contract with customers to ensure the significant risks and rewards of ownership have been transferred. In addition, the Company operates in an industry in which sales revenue is easily influenced by various external factors such as supply and demand of the market, and this may impact the recognition of revenue. Consequently, this is one of the key areas our audit focused on.

4

How the matter was addressed in our audit:

In relation to the key audit matter above, our principal audit procedures included testing the Company’s controls surrounding revenue recognition; assessing whether appropriate revenue recognition policies are applied through comparison with accounting standards and understanding the Company’s main revenue types, its related sales agreements, and sales terms; on a sample basis, inspecting contracts with customers or customers’ orders and assessing whether the accounting treatment of the related contracts (including sales terms) is applied appropriately; performing a test of details of sales revenue and understanding the rationale for any identified significant sales fluctuations and any significant reversals of revenue through sales discounts and sales returns which incurred within a certain period before or after the balance sheet date; and assessing the adequacy of the Company’s disclosures of its revenue recognition policy and other related disclosures.

Other Matters

AU Optronics Corp. has additionally prepared its parent-company-only financial statements as of and for the years ended December 31, 2017 and 2016, on which we have issued an unmodified opinion.

Responsibilities of Management and Those Charged with Governance for the Consolidated Financial Statements

Management is responsible for the preparation and fair presentation of the consolidated financial statements in accordance with Regulations Governing the Preparation of Financial Reports by Securities Issuers and International Financial Reporting Standards, International Accounting Standards, interpretation as well as related guidance endorsed by the Financial Supervisory Commission of the Republic of China, and for such internal control as management determines is necessary to enable the preparation of consolidated financial statements that are free from material misstatement, whether due to fraud or error.

In preparing the consolidated financial statements, management is responsible for assessing the Company’s ability to continue as a going concern, disclosing, as applicable, matters related to going concern, and using the going concern basis of accounting unless management either intends to liquidate the Company or to cease operations, or has no realistic alternative but to do so.

Those charged with governance (inclusive of the Audit Committee) are responsible for overseeing the Company’s financial reporting process.

Auditor’s Responsibilities for the Audit of the Consolidated Financial Statements

Our objectives are to obtain reasonable assurance about whether the consolidated financial statements as a whole are free from material misstatement, whether due to fraud or error, and to issue an auditor’s report that includes our opinion. Reasonable assurance is a high level of assurance, but is not a guarantee that an audit conducted in accordance with the auditing standards generally accepted in the Republic of China will always detect a material misstatement when it exists. Misstatements can arise from fraud or error and are considered material if, individually or in the aggregate, they could reasonably be expected to influence the economic decisions of users taken on the basis of these consolidated financial statements.

As part of an audit in accordance with auditing standards generally accepted in the Republic of China, we exercised professional judgment and maintained professional skepticism throughout the audit. We also:

1. Identified and assessed the risks of material misstatement of the consolidated financial statements, whether due to fraud or error, design and perform audit procedures responsive to those risks, and obtain audit evidence that is sufficient and appropriate to provide a basis for our opinion. The risk of not detecting a material misstatement resulting from fraud is higher than for one resulting from error, as fraud may involve collusion, forgery, intentional omissions, misrepresentations, or the override of internal control.

2. Obtained an understanding of internal control relevant to the audit in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control.

3. Evaluated the appropriateness of accounting policies used and the reasonableness of accounting estimates and related disclosures made by management.

5

1. Concluded on the appropriateness of management’s use of the going concern basis of accounting and, based on the audit evidence obtained, whether a material uncertainty exists related to events or conditions that may cast significant doubt on the Company’s ability to continue as a going concern. If we conclude that a material uncertainty exists, we are required to draw attention in our auditor’s report to the related disclosures in the consolidated financial statements or, if such disclosures are inadequate, to modify our opinion. Our conclusions are based on the audit evidence obtained up to the date of our auditor’s report. However, future events or conditions may cause the Company to cease to continue as a going concern.

2. Evaluated the overall presentation, structure and content of the consolidated financial statements, including the disclosures, and whether the consolidated financial statements represent the underlying transactions and events in a manner that achieves fair presentation.

3. Obtained sufficient appropriate audit evidence regarding the financial information of the entities or business activities within the Company to express an opinion on the consolidated financial statements. We are responsible for the direction, supervision and performance of the group audit.

We communicated with those charged with governance regarding, among other matters, the planned scope and timing of the audit and significant audit findings, including any significant deficiencies in internal control that we identified during our audit.

We also provided those charged with governance with a statement that we have complied with relevant ethical requirements regarding independence, and communicated with them all relationships and other matters that may reasonably be thought to bear on our independence, and where applicable, related safeguards.

From the matters communicated with those charged with governance, we determined those matters that were of most significance in the audit of the consolidated financial statements of the current period and are therefore the key audit matters. We describe these matters in our auditor’s report unless law or regulation precludes public disclosure about the matter or when, in extremely rare circumstances, we determine that a matter should not be communicated in our report because the adverse consequences of doing so would reasonably be expected to outweigh the public interest benefits of such communication.

The engagement partners on the audit resulting in this independent auditors’ report are Wei, Shing-Hai and Lu, Chien-Hui.

Except for the items discussed below, the Company believes that the initial adoption of abovementioned standards or interpretations would not have a material impact on its accounting policies.

a. IFRS 9, Financial Instruments

IFRS 9 replaces the current standards on accounting for financial instruments, IAS 39, Financial Instruments: Recognition and Measurement . IFRS 9 contains three principal classification categories for financial assets: measured at amortized cost, measured at fair value through other comprehensive income (“FVTOCI”) and measured at fair value through profit or loss (“FVTPL”). This Standard eliminates the classification of financial assets under IAS 39 which are held to maturity, loans and receivables and available for sale. In addition, IAS 39 has an exception for the measurement of investments in equity instruments (and related derivatives) that do not have a quoted market price in an active market and for which fair value cannot therefore be measured reliably; such financial instruments are measured at cost. IFRS 9 removes this exception and requires that all equity instruments (and related derivatives) should be measured at fair value.

The Company held equity instruments classified as available-for-sale and financial assets carried at cost at December 31, 2017. Based on the facts and circumstances that existed on that day and considering the Company’s strategy for holding the equity investments, those equity instruments are classified as FVTPL, or designated as FVTOCI upon the adoption of IFRS 9. With regard to equity instruments designated as FVTOCI aforementioned, except dividend income is recognized in profit or loss, all relevant gains and losses are recognized in other comprehensive income. No impairment losses will be recognized in profit or loss, and the cumulative gains or losses previously recognized in other comprehensive income will not be reclassified to profit or loss on disposal.

Notes to Consolidated Financial Statements

Under IFRS 9, a new “expected credit loss” model is used to measure the impairment of financial assets. A loss allowance for expected credit losses should be recognized for financial assets measured at amortized cost, investments in debt instruments measured at fair value through other comprehensive income, lease receivables, contract assets that result from transactions that are within the scope of IFRS 15 or financial guarantee contracts and loan commitments. If the credit risk of the abovementioned financial instruments at the reporting date has increased significantly since initial recognition, a loss allowance is measured at an amount equal to lifetime expected credit losses; if the credit risk has not significantly increased, the loss allowance is measured at an amount equal to the 12-month expected credit losses. If the financial instrument is determined to have low credit risk at the reporting date, it may assume that the credit risk thereof has not increased significantly since initial recognition. However, lifetime expected credit loss measurement always applies for trade receivables and contract assets without a significant financing component.

The Company elected to apply the simplified approach for trade receivables, contract assets and lease receivables to measure the loss allowance at an amount equal to life time expected credit losses. Based on the Company’s assessment, the application of impairment requirements of IFRS 9 would not have a material impact on its consolidated financial statements.

At the initial application of IFRS 9, the Company elected not to restate comparative information for prior years with respect to the classification and measurement (including impairment) changes. The cumulative effect of initially applying this Standard shall be recognized in retained earnings as at January 1, 2018. The Company will disclose information on classification changes and related reconciliation as a result of the application of IFRS 9.

• b. IFRS 15, Revenue from Contracts with Customers

IFRS 15 establishes a five-step model framework for recognizing revenue that apply to all contracts with customers, and will replace existing revenue recognition guidance, including IAS 18, Revenue , IAS 11, Construction Contracts , and the related interpretations.

(i) Sales of goods

Under IFRS 15, revenue for the sale of goods is recognized when a customer obtains control of the goods. For certain contracts that permit a customer to return goods, revenue is recognized to the extent that it is highly probable that a significant reversal in the amount of cumulative revenue recognized will not occur.

For certain contracts with volume discounts to customers, under IFRS 15, revenue is recognized on a net basis of contract price less estimated volume discounts, and only to the extent that it is highly probable that a significant reversal will not occur.

Notes to Consolidated Financial Statements

Under IFRS 15, a refund liability is measured at the amount of consideration received (or receivable) for which an entity does not expect to be entitled. The refund liability shall be updated at the end of each reporting period for changes in circumstances.

Based on the Company’s assessment, the application of IFRS 15 would not result in material differences and impact in the timing of revenue recognition.

(ii) Rendering of services

Under IFRS 15, for rendering of services, the consideration of the entire contract is allocated on a basis of a relative stand-alone selling price of the services. The stand-alone selling price is determined based on the list price of service at which the Company sells that service separately.

Based on the Company’s assessment, the application of IFRS 15 would not have a material impact on the revenue recognition.

(iii) Transition

The Company elected to apply IFRS 15 using the cumulative effect method, and meanwhile, chose to use the practical expedient for completed contracts. That is, the Company elected to apply this Standard retrospectively only to contracts that are not completed contracts at the date of initial application. The cumulative effect resulting from the initial application of this Standard shall be recognized as an adjustment to retained earnings at January 1, 2018, and the comparative information for prior periods is not required to be restated.

c. Amendments to IAS 7, Disclosure Initiative

The amendments require an entity to provide disclosures that enable users of financial statements to evaluate changes in liabilities arising from financing activities, including both changes arising from cash flows and non-cash changes.

The Company is expected to disclose a reconciliation between the opening and closing balances for liabilities with changes from financing activities to meet the requirement as stated above.

• (3) The IFRSs issued by the IASB but not yet endorsed by the FSC

A summary of the new standards and amendments issued by the IASB but not yet endorsed by the FSC is set out below.

New, Revised or Amended Standards and Interpretations	Effective Date Issued by IASB
Amendments to IFRS 10 and IAS 28,Sale or Contribution of Assets between an Investor and its Associate or Joint Venture IFRS 16,Leases IFRS 17,Insurance Contracts Amendments to IAS 28,Long-term Interests in Associates and Joint Ventures Amendments to IFRS 9, Prepayment Features with Negative Compensation IFRIC 23,Uncertainty over Income Tax Treatments Annual Improvements to IFRSs 2015 – 2017 Cycle	Subject to IASB’s announcement January 1, 2019 January 1, 2021 January 1, 2019 January 1, 2019 January 1, 2019 January 1, 2019

Except for the item discussed below, the Company believes that the initial adoption of abovementioned standards or interpretations would not have a material impact on its accounting policies.

IFRS 16, Leases

IFRS 16 sets out the accounting standards for leases that will replace IAS 17, Leases and the related interpretations.

Under IFRS 16, a lessee is required to recognize a right-of-use asset and a lease liability on the balance sheet for all leases with exception for leases of low-value assets and short-term leases which the Company may elect to apply the accounting method similar to the accounting for operating lease under IAS 17. Additionally, a depreciation expense charged on the right-of-use asset and an interest expense accrued on the lease liability, for which interest is computed by using effective interest method, are recognized separately on the statement of comprehensive income. On the statement of cash flows, cash payments for the principal amount and the interest of the lease liability are generally classified within financing activities.

When IFRS 16 becomes effective, as a lessee, the Company may elect to apply this Standard either retrospectively to each prior reporting period presented or retrospectively with a recognition of cumulative effect of the initial adoption of this Standard at the date of initial adoption. As a lessor, the Company is not required to make any adjustments for leases except it is an intermediate lessor in a sub-lease.

Notes to Consolidated Financial Statements

The Company has performed a preliminary assessment and identification over its current operating leases whether they are in scope of IFRS 16. The main impact to the Company may arise from its lease contracts of land and plant which are currently accounted as operating lease. Please refer to note 6(18) for the related disclosures. The Company will identify whether a contract that contains a lease meets the definition of a lease under this Standard, and if so, a right-of-use asset and a lease liability shall be recognized. The related impact for adoption of IFRS 16 by the Company will be disclosed when the Company completes the assessment.

Except for the aforementioned impacts, as of the date that the accompanying consolidated financial statements were issued, the Company continues in assessing the potential impact on its financial position and results of operations as a result of the application of other standards, interpretations and amendments. The potential impact will be disclosed when the assessment is complete.

b. Functional and presentation currency

The functional currency of each individual consolidated entity is determined based on the primary economic environment in which the entity operates. The Company’s consolidated financial statements are presented in New Taiwan Dollar (“NTD”), which is also AUO’s functional currency. All financial information presented in NTD has been rounded to the nearest thousand, unless otherwise noted.

(3) Basis of consolidation

a. Principle of preparation of the consolidated financial statements

The Company includes in its consolidated financial statements the results of operations of all controlled entities in which the Company is exposed to, or has rights to, variable returns from its involvement with the entity and has the ability to affect those returns through its power over the entity. All significant inter-company transactions, income and expenses are eliminated in the consolidated financial statements.

The financial statements of subsidiaries are included in the consolidated financial statements from the date that control commences until the date that control ceases. Total comprehensive income (loss) in a subsidiary is allocated to the shareholders of AUO and the non-controlling interests even if this results in the non-controlling interests having a deficit balance.

Subsidiaries’ financial statements are adjusted to align the accounting policies with those of the Company.

Changes in the Company’s ownership interests in a subsidiary that do not result in a loss of control are accounted for as equity transactions. The carrying amounts of the Company’s investment and non-controlling interests are adjusted to reflect the changes in their relative interests in the subsidiary. Any difference between such adjustment and the fair value of the consideration paid or received is recognized directly in equity and attributed to shareholders of AUO.

Upon the loss of control, the Company derecognizes the carrying amounts of the assets and liabilities of the subsidiary and non-controlling interests. Any interest retained in the former subsidiary is measured at fair value when control is lost. The gain or loss is measured as the difference between: (i) the aggregate of the fair value of the consideration received and the fair value of any retained non-controlling investment in the former subsidiary at the date when the Company losses control; and (ii) the aggregate of the carrying amount of the former subsidiary’s assets (including goodwill), liabilities and non-controlling interests at the date when the Company losses control. The Company accounts for all amounts previously recognized in other comprehensive income in relation to that subsidiary on the same basis as would be required if the Company had directly disposed of the related assets or liabilities.

(4) Foreign currency

In preparing the financial statements of each individual consolidated entity, transactions in currencies other than the entity’s functional currency (foreign currencies) are recognized at exchange rates at the dates of the transactions. Monetary assets and liabilities denominated in foreign currencies at the reporting date are retranslated to the functional currency at the exchange rate at that date and the resulting exchange differences are included in profit or loss for the year. Non-monetary assets and liabilities denominated in foreign currencies that are measured at fair value are retranslated to the functional currency at the exchange rate at the date when the fair value was determined. The resulting exchange differences are included in profit or loss for the year except for those arising from the retranslation of nonmonetary items in respect of which gains and losses are recognized directly in other comprehensive income, in which case, the exchange differences are also recognized directly in other comprehensive income. Non-monetary items in foreign currencies that are measured at historical cost are translated using the exchange rate at the date of the transaction.

Exchange differences arising from the effective portion of changes in the fair value of derivatives that are designated and qualified as cash flow hedges are recognized in other comprehensive income.

For the purpose of presenting consolidated financial statements, the assets and liabilities of the Company’s foreign operations are translated into NTD using the exchange rates at each reporting date. Income and expenses of foreign operations are translated at the average exchange rates for the period unless the exchange rates fluctuate significantly during the period; in that case, the exchange rates at the dates of the transactions are used. Foreign currency differences are recognized in other comprehensive income within equity.

• (5) Classification of current and non-current assets and liabilities

An asset is classified as current when:

• a. The asset expected to realize, or intends to sell or consume, in its normal operating cycle;

• b. The asset primarily held for the purpose of trading;

• c. The asset expected to realize within twelve months after the reporting date; or

• d. Cash and cash equivalent excluding the asset restricted to be exchanged or used to settle a liability for at least twelve months after the reporting date.

All other assets are classified as non-current.

A liability is classified as current when:

• a. The liability expected to settle in its normal operating cycle;

• b. The liability primarily held for the purpose of trading;

• c. The liability is due to be settled within twelve months after the reporting date; or

• d. The Company does not have an unconditional right to defer settlement of the liability for at least twelve months after the reporting date. Terms of a liability that could, at the option of the counterparty, result in its settlement by the issue of equity instruments, do not affect its classification.

All other liabilities are classified as non-current.

• (6) Cash and cash equivalents

Cash comprise cash balances and demand deposits. Cash equivalents comprise short-term highly liquid investments that are readily convertible into known amounts of cash and are subject to an insignificant risk of changes in their fair value. Deposits with short-term maturity but not for investments and other purposes and are qualified with the aforementioned criteria are classified as cash equivalent.

• (7) Financial Instruments

Financial assets and financial liabilities are initially recognized when the Company becomes a party to the contractual provisions of the instruments.

23

AU OPTRONICS CORP. AND SUBSIDIARIES

Notes to Consolidated Financial Statements

a. Financial assets

• (i) The Company classifies financial assets into the following categories: financial assets measured at fair value through profit or loss, receivables and available-forsale financial assets.

• (a) Financial assets measured at fair value through profit or loss

The Company has certain financial assets classified in this category to hedge its exposure to foreign exchange and interest rate risks arising from operating and financing activities. When a derivative financial instrument is not effective as a hedge the Company accounts for it as a financial asset or liability measured at fair value through profit or loss. See note 4(7)c. for further detail of the Company’s derivative financial instruments and hedge accounting policy.

• (b) Available-for-sale financial assets

Available-for-sale financial assets are non-derivative financial assets that are either designated as available-for-sale or are not classified as receivables or financial assets measured at fair value through profit or loss. Available-forsale financial assets are recognized initially at fair value, plus any directly attributable transaction cost. Subsequent to initial recognition, they are measured at fair value and changes therein, other than impairment losses, dividend income and foreign currency differences related to monetary financial assets, are recognized in other comprehensive income and presented within equity in unrealized gains (losses) on available-for-sale financial assets. When an investment is derecognized, the cumulative gain or loss in equity is reclassified to profit or loss and presented under nonoperating income and expenses. A regular way, purchase or sale of financial assets shall be recognized and derecognized, as applicable, using trade date accounting.

Investments in equity instruments that do not have a quoted market price in an active market, and whose fair value cannot be reliably measured, are carried at their cost less any impairment losses and presented under the heading of financial assets carried at cost.

Cash dividends on equity instruments are recognized under non-operating income and expenses on the date that the Company’s right to receive dividends is established.

24

AU OPTRONICS CORP. AND SUBSIDIARIES

Notes to Consolidated Financial Statements

(c) Receivables

Receivables are financial assets with fixed or determinable payments that are not quoted in an active market. Receivables comprise trade receivables and other receivables. Such assets are recognized initially at fair value, plus any directly attributable transaction costs. Subsequently, receivables are measured at amortized cost using the effective interest method, less any impairment. If the effect of discounting is immaterial, the short-term receivables are measured at the original amount.

(ii) Impairment of financial assets

Financial assets not measured at fair value through profit or loss are assessed at each reporting date for indicators of impairment. Financial assets are considered to be impaired if an objective evidence indicates that, as a result of one or more events that occurred after the initial recognition of the financial asset, the estimated future cash flows of those assets have been negatively impacted.

When an available-for-sale equity security is considered to be impaired, cumulative gains or losses previously recognized in other comprehensive income are reclassified to profit or loss. Such impairment losses are not reversed through profit or loss. However, any subsequent recovery in the fair value of an impaired available-for-sale equity security is recognized in other comprehensive income and accumulated in other components of equity.

If no impairment exists for receivables individually assessed, the Company further assesses those receivables for impairment on a collective basis. An impairment loss for trade receivables is reflected in an allowance account against the receivables. When it is determined a receivable is uncollectible, it is written off from the allowance account. Any subsequent recovery of receivable previously written off is credited against the allowance account. Changes in the amount of the allowance accounts are recognized in profit or loss.

When a financial asset carried at cost is considered to be impaired, an impairment loss for this financial asset is recognized and reduced directly from its carrying amount. Such impairment loss recognized is not reversed through profit or loss in subsequent periods.

Bad debt expenses and reversal of allowance for doubtful debts for trade receivables are recognized in general and administrative expenses while impairment losses and reversal of impairment for financial assets other than receivables are recognized under non-operating income and expenses.

Notes to Consolidated Financial Statements

(iii) De-recognition of financial assets

The Company derecognizes financial assets when the contractual rights of the cash inflow from the asset are terminated, or when the Company transfers substantially all the risks and rewards of ownership of the financial assets to another entity.

On de-recognition of a financial asset in its entirety, the difference between the carrying amount and the sum of the consideration received or receivable and any cumulative gain or loss that had been recognized in other comprehensive income is recognized in profit or loss.

b. Financial liabilities

• (i) The Company classifies financial liabilities into the following categories: financial liabilities measured at fair value through profit or loss and other financial liabilities.

• (a) Financial liabilities measured at fair value through profit or loss

The Company designates financial liabilities in this category as held for trading for the purpose of hedging exposure to foreign exchange and interest rate risks arising from operating and financing activities. When a derivative financial instrument is not effective as a hedge the Company accounts for it as a financial asset or liability measured at fair value through profit or loss. See note 4(7)c. for further detail of the Company’s derivative financial instruments and hedge accounting policy.

The Company designates financial liabilities, other than the one mentioned above, as measured at fair value through profit or loss at initial recognition. Attributable transaction costs are recognized in profit or loss as incurred. Financial liabilities in this category are subsequently measured at fair value and changes therein, which takes into account any interest expense, are recognized in profit or loss and presented under non-operating income and expenses.

(b) Other financial liabilities

Financial liabilities not classified as held for trading, or not designated as measured at fair value through profit or loss (including loans and borrowings, trade and other payables), are measured at fair value, plus any directly attributable transaction cost at the time of initial recognition. Subsequent to initial recognition, they are measured at amortized cost calculated using the effective interest method, except for insignificant recognition of interest expense from short-term borrowings and trade payables. Interest expense not capitalized as an asset cost is recognized in profit or loss and presented under non-operating income and expenses.

AU OPTRONICS CORP. AND SUBSIDIARIES

Notes to Consolidated Financial Statements

(ii) De-recognition of financial liabilities

The Company derecognizes financial liabilities when the contractual obligation has been discharged, cancelled or expired. The difference between the carrying amount and the consideration paid or payable, including any non-cash assets transferred or liabilities assumed is recognized in profit or loss and presented under non-operating income and expenses.

(iii) Offsetting of financial assets and liabilities

The Company presents financial assets and liabilities on a net basis when the Company has the legally enforceable rights to offset, and intends to settle such financial assets and liabilities on a net basis or to realize the assets and settle the liabilities simultaneously.

c. Derivative financial instruments and hedge accounting

The Company holds derivative financial instruments to hedge its foreign currency and interest rate exposures. Derivatives are recognized initially at fair value, and attributable transaction costs are recognized in profit or loss as incurred. Subsequent to initial recognition, derivatives are measured at fair value, and changes therein are recognized in profit or loss and presented under non-operating income and expenses. When a derivative is designated as a hedging instrument, its timing of recognition in profit or loss is determined based on the nature of the hedging relationship. When the fair value of a derivative instrument is positive, it is classified as a financial asset, and when the fair value is negative, it is classified as a financial liability.

When a derivative is designated as a cash flow hedge, the changes in the fair value of the derivative that is determined to be effective is recognized in other comprehensive income. Any ineffective portion of changes in the fair value of the derivative is recognized in profit or loss and presented under non-operating income and expenses.

When the hedged item is recognized in profit or loss, amounts previously recognized in other comprehensive income and accumulated in equity are reclassified to profit or loss in the same period or periods during which the hedged item affects profit or loss, and it is presented in the same accounting caption with the hedged item recognized in the consolidated statements of comprehensive income. When a cash flow hedge is expected to recognize as a non-financial asset or liability, amounts previously recognized in other comprehensive income and accumulated in other components of equity are reclassified as the initial cost of the non-financial asset or liability.

The cost of inventories includes all necessary expenditures and charges for bringing the inventory to a stable, useable and marketable condition and location. Inventories are recorded at cost, and cost is determined using the weighted-average method. The production overhead is allocated based on the normal capacity of the production facilities. Inventories are measured at the lower of cost or net realizable value. Net realizable value for finished goods and work in process is calculated based on the estimated selling price less all estimated costs of completion and necessary selling costs.

(9) Noncurrent assets held for sale

Noncurrent assets are classified as held for sale when their carrying amounts are expected to be recovered primarily through sale rather than through continuing use. Such noncurrent assets must be available for immediate sale in their present condition and the sale is highly probable within one year. When classified as held for sale, the assets are measured at the lower of their carrying amount and fair value less costs to sell. Impairment losses on initial classification as held for sale and subsequent gains or losses on re-measurement are recognized in profit or loss. However, subsequent gains are not recognized in excess of the cumulative impairment loss that has been recognized.

When intangible assets and property, plant and equipment are classified as held for sale, they are no longer amortized or depreciated. In addition, once an equity-accounted investee is classified as held for sale, it is no longer equity accounted.

(10) Investments in associates

Associates are those entities in which the Company has the power to exercise significant influence, but not control or joint control, over their financial and operating policies.

Investments in associates are accounted for using the equity method and are recognized initially at cost. The cost of the investment includes transaction costs. The carrying amount of the investment in associates includes goodwill, which is arising from the acquisition, less any accumulated impairment losses.

The difference between acquisition cost and fair value of associates’ identifiable assets and liabilities as of the acquisition date is accounted for as goodwill. Goodwill is included in the original investment cost of acquired associates and is not amortized. If the fair value of identified assets and liabilities is in excess of acquisition cost, the remaining excess over acquisition cost is recognized as a gain in profit or loss.

If an equity security is not acquired through cash, that is, by providing services or other assets, then the fair value of such security or the fair value of the services or assets surrendered, whichever is more objectively determinable, is the purchase price of the security. If an equity investment of associates is acquired by providing subsequent services and the cost is determined based on the fair value of such services, the Company defers and recognizes revenue using a reasonable amortization method over the future period when the service is rendered.

Notes to Consolidated Financial Statements

The consolidated financial statements include the Company’s share of the profit or loss and other comprehensive income of associates, after adjustments to align the accounting policies with those of the Company, from the date that significant influence commences until the date that significant influence ceases. When an associate incurs changes in its equity not derived from profit or loss and other comprehensive income, the Company recognizes all the equity changes in proportion to its ownership interest in the associate as capital surplus provided that the ownership interest in the associate remain unchanged.

The Company discontinues the use of the equity method from the date when the Company ceases to have significant influence over an associate, and then measures the retained interests at fair value at that date. The difference between the carrying amount of the investment at the date the equity method was discontinued and the fair value of the retained interests along with any proceeds from disposing of a part interest in the associate is recognized in profit or loss. Moreover, the Company accounts for all amounts previously recognized in other comprehensive income in relation to that investment on the same basis as would be required if the associate had directly disposed of the related assets or liabilities. If the Company’s ownership interest in an associate is reduced, but the Company continues to apply the equity method, the Company shall reclassify to profit or loss the proportion of the gain or loss that had previously been recognized in other comprehensive income relating to that reduction in ownership interest on the same basis as mentioned above.

If an investment in an associate becomes an investment in a joint venture or an investment in a joint venture becomes an investment in an associate, the Company continues to account for the investment using equity method and does not remeasure the interest previously held.

When the Company subscribes to additional shares in an associate at a percentage different from its existing ownership percentage, the resulting carrying amount of the investment differs from the amount of the Company’s proportionate interest in the net assets of the associate. The Company records such a difference as an adjustment to investments with the corresponding amount charged or credited to capital surplus. If the capital surplus arising from investment accounted for under the equity method in associates is insufficient to offset with the said corresponding amount, the differences will be charged or credited to retained earnings. If the Company’s ownership interest is reduced due to circumstances as mentioned above, the proportionate amount of the gains or losses previously recognized in other comprehensive income relating to that associate or joint venture shall be reclassified to profit or loss on the same basis as would be required if the associate or joint venture had directly disposed of the related assets or liabilities.

At the end of each reporting period, if there is any indication of impairment, the entire carry amount of the investment including goodwill is tested for impairment as a single asset, by comparing its recoverable amount with its carrying amount. An impairment loss recognized forms part of the carrying amount of the investment in associates. Accordingly, any reversal of that impairment loss is recognized to the extent that the recoverable amount of the investment subsequently increases.

29

AU OPTRONICS CORP. AND SUBSIDIARIES

Notes to Consolidated Financial Statements

Unrealized profits or losses resulting from the transactions between the Company and associates are eliminated to the extent of the Company’s interest in the associate.

When the Company’s share of losses exceeds its interest in an associate, the carrying amount of that interest, including any long-term investments that form part thereof, is reduced to zero, and the recognition of further losses is discontinued except to the extent that the Company has a legal or contractual obligation, or has made payments on behalf of the investee.

(11) Investments in joint ventures

Joint venture is a joint arrangement whereby the Company and other parties agreed to share the control of the arrangement, and have rights to the net assets of the arrangement. Unanimous consent from the parties sharing control is required when decisions about the relevant activities of the arrangement. Investments in joint venture are accounted for in the Company’s consolidated financial statements under the equity method.

(12) Investment property

Investment property is the property held either to earn rental income or for capital appreciation or for both, but not for sale in the ordinary course of business, use in the production or supply of goods or services or for administrative purposes. Investment property is measured at cost on initial recognition. Subsequent to initial recognition, investment properties are measured at initial acquisition cost less any subsequent accumulated depreciation. Depreciation methods, useful lives and residual values are in accordance with the policy of property, plant and equipment. Cost includes expenditure that is directly attributable to the acquisition of the investment property.

An investment property is reclassified to property, plant and equipment at its carrying amount when the use of the investment property changes.

(13) Property, plant and equipment

a. Recognition and measurement

Items of property, plant and equipment are measured at cost less accumulated depreciation and accumulated impairment losses. Cost includes expenditure that is directly attributed to the acquisition of the asset, any cost directly attributable to bringing the asset to the location and condition necessary for it to be capable of operating in the manner intended by management, the initial estimate of the costs of dismantling and removing the item and restoring the site on which it is located, and any borrowing cost that is eligible for capitalization. The cost of the software is capitalized as part of the equipment if the purchase of the software is necessary for the equipment to be capable of operating.

30

AU OPTRONICS CORP. AND SUBSIDIARIES

Notes to Consolidated Financial Statements

When part of an item of property, plant and equipment with a cost that is significant in relation to the total cost of the item and the useful life or the depreciation method of the significant part is different from another significant part of that same item, it is accounted for as a separate item (significant component) of property, plant and equipment.

The gain or loss arising from the derecognition of an item of property, plant and equipment is determined as the difference between the net disposal proceeds, if any, and the carrying amount of the item, and is recognized in profit or loss.

b. Subsequent costs

Subsequent expenditure is capitalized only when it is probable that the future economic benefits associated with the expenditure will flow to the Company and the cost of the item can be measured reliably. Ongoing repairs and maintenance is recognized in profit or loss as incurred.

• c. Depreciation

Excluding land, depreciation is provided over the estimated useful lives of the respective assets, considering significant components of an individual asset, on a straight-line basis less any residual value. If a component has a useful life that is different from the remainder of that asset, that component is depreciated separately. The depreciation charge is recognized in profit or loss.

Leased assets are depreciated over their useful lives, provided that it is reasonably certain that the Company will obtain ownership by the end of the lease term; otherwise are depreciated over the shorter of the lease term and their useful lives.

The estimated useful lives of the assets, except for land are as follows:

• (i) Buildings: 20~50 years

• (ii) Machinery and equipment: 3~10 years

• (iii) Other equipment: 3~6 years

Depreciation methods, useful lives, and residual values are reviewed at each annual reporting date and, if necessary, adjusted as appropriate. Any changes therein are accounted for as changes in accounting estimates.

• d. Reclassification to investment property

A property is reclassified to investment property at its carrying amount when the use of the property changes from owner-occupied to investment purpose.

Notes to Consolidated Financial Statements

(14) Long-term prepaid rent

Long-term prepaid rent is for the use right of land (classified as other noncurrent assets), which is amortized over the shorter of economic useful life or covenant period on a straightline basis.

(15) Leases

• a. Lessor

Lease income from an operating lease is recognized in profit or loss on a straight-line basis over the lease term. Initial direct costs incurred in negotiating and arranging an operating lease are added to the carrying amount of the leased asset, and recognized as an expense on a straight-line basis over the lease term.

• b. Lessee

Payments made under operating lease (excluding insurance and maintenance expenses) are recognized in profit or loss on a straight-line basis over the term of the lease.

(16) Intangible assets

• a. Goodwill

Goodwill is recognized when the purchase price exceeds the fair value of identifiable net assets acquired in a business combination. Goodwill is measured at cost less accumulated impairment losses.

Investor-level goodwill is included in the carrying amounts of the equity investments. The impairment losses for the goodwill within the equity-accounted investees are accounted for as deductions of carrying amounts of investments in equity-accounted investees.

• b. Research and development

During the research phase, activities are carried out to obtain and understand new scientific or technical knowledge. Expenditures during this phase are recognized in profit or loss as incurred.

Expenditure arising from development is capitalized as an intangible asset when the Company demonstrates all of the following:

• (i) the technical feasibility of completing the intangible asset so that it will be available for use or sale;

• (ii) its intention to complete the intangible asset and use or sell it;

• (iii) its ability to use or sell the intangible asset;

32

AU OPTRONICS CORP. AND SUBSIDIARIES

Notes to Consolidated Financial Statements

• (iv) the probability that the intangible asset will generate probable future economic benefits;

• (v) the availability of adequate technical, financial and other resources to complete the development and to use or sell the intangible asset; and

• (vi) its ability to measure reliably the expenditure attributable to the intangible asset during its development.

Development expenditure which fails to meet the criteria for recognition as an intangible asset is reflected in profit or loss when incurred. Capitalized development expenditure is measured at cost less accumulated amortization and any accumulated impairment losses.

• c. Other intangible assets

Other intangible assets acquired are measured at cost less accumulated amortization and any accumulated impairment losses.

• d. Subsequent expenditure

Subsequent expenditure is capitalized only when it increases the future economic benefits embodied in the specific asset to which it relates. All other expenditure, including expenditure on internally generated goodwill and brands, is recognized in profit or loss as incurred.

• e. Amortization

The depreciable amount of an intangible asset is the cost less its residual value. Other than goodwill and intangible assets with indefinite useful life, an intangible asset with a finite useful life is amortized over 3 to 20 years using the straight-line method from the date that the asset is made available for use. The amortization charge is recognized in profit or loss.

The residual value, amortization period, and amortization method are reviewed at least annually at each annual reporting date, and any changes therein are accounted for as changes in accounting estimates.

• (17) Impairment – non-financial assets

Other than inventories, deferred tax assets and noncurrent assets held for sale, the carrying amounts of the Company’s investment property measured at cost and long-term nonfinancial assets (property, plant and equipment and other intangible assets with finite useful lives), are reviewed at the reporting date to determine whether there is any indication of impairment. When there is an indication of impairment exists for the aforementioned assets, the recoverable amount of the asset is estimated. If it is not possible to estimate the recoverable amount of an individual asset, the Company estimates the recoverable amount of the cash-generating unit (“CGU”) to which the asset has been allocated to.

33

AU OPTRONICS CORP. AND SUBSIDIARIES

Notes to Consolidated Financial Statements

In performing an impairment test for the aforementioned assets, the estimated recoverable amount is evaluated in terms of an asset or a CGU. Any excess of the carrying amount of the asset or its related CGU over its recoverable amount is recognized as an impairment loss. The recoverable amount of an asset or a CGU is the higher of its fair value less costs of disposal and its value in use.

If there is evidence that the accumulated impairment loss of an asset other than goodwill and intangible assets with indefinite useful lives in prior years no longer exists or has diminished, the amount previously recognized as an impairment loss is reversed, and the carrying amount of the asset or CGU is increased to the revised estimate of its recoverable amount. The increase in the carrying amount shall not exceed the carrying amount (net of depreciation or amortization) had no impairment loss been recognized for the asset in prior years.

For goodwill and intangible assets with indefinite useful lives or that are not yet available for use, are required to be tested for impairment at least annually. Any excess of the carrying amount of the asset over its recoverable amount is recognized as an impairment loss.

Goodwill acquired in a business combination is allocated to CGUs that are expected to benefit from the synergies of the combination. Impairment losses recognized in respect of a CGU are allocated first to reduce the carrying amount of any goodwill allocated to the unit, then the carrying amounts of the other assets in the unit on a pro rata basis. The impairment loss recognized on goodwill and intangible assets with indefinite useful lives is not reversed.

(18) Provisions

A provision is recognized for a legal or constructive obligation arising from a past event, if there is probable outflow of resources and the amount can be estimated reliably. Provisions are determined by discounting the expected future cash flows at a pre-tax rate that reflects the current market assessments of the time value of money and the risks specific to the liability. The unwinding of the discount is recognized as interest expense.

a. Warranties

A provision for warranties is recognized when the underlying products or services are sold. The provision is weighting factors based on historical experience of warranty claims rate and other possible outcomes against their associated probabilities.

b.

Decommissioning obligation

The Company is subject to decommissioning obligations related to certain items of property, plant and equipment. Such decommissioning obligations are primarily attributable to clean-up costs, including deconstruction, transportation, and recover costs. The unwinding of the discount based on original discount rate is recognized in profit or loss as interest expense over the periods with corresponding increase in the carrying amounts of the accrued decommissioning costs. The carrying amount of the accruals at the end of the assets’ useful lives is the same as the estimated decommissioning costs.

Notes to Consolidated Financial Statements

c. Onerous contracts

A provision for onerous contracts is recognized when the expected benefits to be derived by the Company from a contract are lower than the unavoidable cost of meeting its obligations under the contract. The provision is measured at the present value of the lower of the expected cost of terminating the contract and the expected net cost of continuing with the contract. Before a provision is established, the Company recognizes any impairment loss on the assets associated with that contract.

d. Loss contingencies

Provision for loss contingencies arising from claims, assessments, litigation, fines, and penalties and other sources are recognized when it is probable the present obligation as a result of a past event will result in an outflow of resources and the amount can be reasonably estimated. Legal costs incurred in connection with loss contingencies are expensed as incurred. Management periodically assesses the obligation of all litigation and claims and relative legal costs.

Provisions recognized are the best estimates of the consideration for settling the present obligation at each reporting date.

(19) Revenue recognition

a. Goods sold

Revenue from the sale of goods in the course of ordinary activities is measured at the fair value of the consideration received or receivable, net of returns, trade discounts and volume rebates. Revenue is recognized when the significant risks and rewards of ownership have been transferred to the customer, recovery of the consideration is probable, the associated costs and possible return of goods can be estimated reliably, there is no continuing management involvement with the goods, and the amount of revenue can be measured reliably. If it is probable that discounts will be granted and the amount can be measured reliably, then the discount is recognized as a reduction of revenue as the sales are recognized.

The timing of the transfers of risks and rewards varies depending on the individual terms of the sales agreement.

b. Government grants

Grants that compensate the Company for research and development expenses incurred are recognized as other income in profit or loss on a systematic basis in the periods in which the expenses are recognized.

35

AU OPTRONICS CORP. AND SUBSIDIARIES

Notes to Consolidated Financial Statements

(20) Employee benefits

a. Defined contribution plans

Obligations for contributions to defined contribution pension plans are recognized as an employee benefit expense in profit or loss in the periods during which services are rendered by employees.

b. Defined benefit plans

The Company’s net obligation in respect of defined benefit pension plans is calculated separately for each benefit plan by estimating the amount of future benefit that employees have earned in the current and prior periods, discounting that amount and deducting the fair value of any plan assets. Discount rate is determined by reference to the yield rate of Taiwan government bonds at the reporting date. The calculation of defined benefit obligations is performed annually by a qualified actuary using the Projected Unit Credit Cost Method.

Remeasurements of the net defined benefit liability (asset) which comprise actuarial gains and losses, the return on plan assets (excluding interest) and the effect of the asset ceiling (if any, excluding interest), are recognized in other comprehensive income in the period in which they occur, and which then are reflected in retained earnings and will not be reclassified to profit or loss.

c. Short-term employee benefits

Short-term employee benefit obligations, which are due to be settled within twelve months are measured on an undiscounted basis and are expensed as the related service is provided.

The expected cost of cash bonus or profit-sharing plans, which is anticipated to be paid within one year, are recognized as a liability when the Company has a present legal or constructive obligation to pay this amount as a result of past service provided by the employee, and the obligation can be estimated reliably.

• (21) Share-based payment arrangements

The compensation cost of employee share-based payment arrangements is measured based on the fair value at the date on which they are granted. The compensation cost is recognized, together with a corresponding increase in equity, over the periods in which the performance and/or service conditions are being fulfilled. The cumulative expense recognized for sharebased payment arrangements at each reporting date reflects the extent to which the vesting period has passed and the Company’s estimate of the quantity of equity instruments that will ultimately vest.

36

AU OPTRONICS CORP. AND SUBSIDIARIES

Notes to Consolidated Financial Statements

For share-based payment awards with non-vesting conditions, the grant-date fair value of the share-based payment is measured to reflect such conditions, and there is no true-up for differences between expected and actual outcomes.

(22) Income taxes

Income tax expense comprises current and deferred taxes.

a. Current taxes

Current taxes comprise the expected tax payable or receivable on the taxable income or losses for the year and any adjustments to tax payable or receivable in respect of previous years. It is measured using tax rates enacted or substantively enacted tax rate at the reporting date.

In accordance with the ROC Income Tax Act, undistributed earnings from the companies located in the Republic of China, if any, is subject to an additional 10% surtax. The 10% tax on unappropriated earnings is expensed in the year the shareholders approved the distributions which is the year subsequent to the year the earnings arise.

b. Deferred taxes

Deferred taxes are recognized in respect of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Deferred tax liabilities are recognized for temporary difference of future taxable income. Deferred tax assets are recognized for unused tax losses, unused tax credits and deductible temporary differences to the extent it is probable that future taxable profits will be available against which they can be utilized.

Deferred tax assets are reviewed at each reporting date, by considering nature of industry cycles, statutory tax deduction years and projected future taxable income, and reduced to the extent that it is no longer probable that future taxable profits will be available to allow all or part of the deferred tax asset to be recovered. Deferred tax assets which originally not recognized is also reviewed at each reporting date and recognized to the extent that it is probable that future taxable profits will be available to allow all or part of the deferred tax asset to be recovered.

Deferred taxes liabilities are recognized for taxable temporary differences related to investments in subsidiaries, associates and joint arrangements, however, if the Company is able to control the timing of the reversal of the taxable temporary differences and it is probable that they will not reverse in the foreseeable future, deferred taxes are not recognized.

37

AU OPTRONICS CORP. AND SUBSIDIARIES

Notes to Consolidated Financial Statements

Deferred tax is measured at the tax rates that are expected to be applied to temporary differences when the reverse, using tax rates enacted or substantively enacted tax rate on the reporting date. Deferred tax assets and liabilities are offset only if certain criteria are met.

Current taxes and deferred taxes are recognized in profit or loss except to the extent that it relates to items recognized directly in equity or other comprehensive income.

(23) Business combinations

The Company accounts for business combinations using the acquisition method. The consideration transferred in the acquisition is measured at fair value, as are identifiable net assets acquired. Goodwill is measured as the excess of the aggregate of the consideration transferred and the amount of any non-controlling interests in the acquiree over the net identifiable assets acquired and liabilities assumed. If the fair value of the net assets acquired is in excess of the aggregate consideration transferred, after reassessing all of the assets acquired and all of the liabilities assumed being properly identified, the difference is recognized in profit or loss as a gain on bargain purchase.

Acquisition-related costs are expensed as incurred, except that the costs are related to the issue of debt or equity securities.

Each identifiable asset and liability is measured at its acquisition-date fair value. Noncontrolling interests in an acquiree that are present ownership interests and entitle their holders to a proportionate share of the entity’s net assets in the event of liquidation are measured at either fair value or the present ownership instruments’ proportionate share in the recognized amounts of the acquiree’s net identifiable assets. All other components of non-controlling interests shall be measured at their acquisition-date fair values, unless another measurement basis is required by TIFRSs.

(24) Earnings (loss) per share

Basic earnings (loss) per share is computed by dividing profit or loss attributable to the shareholders of AUO by the weighted-average number of common shares outstanding during the period. In computing diluted earnings per share, profit or loss attributable to the shareholders of AUO and the weighted-average number of common shares outstanding during the period are adjusted for the effects of dilutive potential common stock, assuming dilutive share equivalents had been issued.

The weighted-average outstanding shares are retroactively adjusted for the effects of stock dividends transferred from retained earnings and capital surplus to common stock.

(25) Operating segments

An operating segment is a component of an entity that engages in business activities from which it may earn revenue and incur expenses (including revenues and expenses relating to transactions with other components of the same entity). Operating results are reviewed regularly by the Company’s chief operating decision maker (“CODM”) to make decisions pertaining to the allocation of resources to the segment and to assess its performance. Meanwhile, discrete financial information for operating results is available.

5. Critical Accounting Judgments and Key Sources of Estimation and Assumption Uncertainty

The preparation of the consolidated financial statements in conformity with the Regulations and TIFRSs requires management to make judgments, estimates and assumptions that affect the application of the accounting policies and the reported amount of assets, liabilities, income and expenses. Actual results may differ from these estimates.

Estimates and underlying assumptions are reviewed by management on an ongoing basis. Revisions to accounting estimates are recognized in the period in which the estimates are revised and in any future periods affected.

Information about critical judgments, estimates and assumptions in applying accounting policies that have the most significant effect on the amounts recognized in the consolidated financial statements is included in the following notes:

• (1) Estimate of provisions

Provision for warranty is estimated when product revenue is recognized. The estimate has been made based on the quantities within the warranty period, the historical and anticipated warranty claims rate associated with similar products and services, and the projected unit cost of maintenance. The Company regularly reviews the basis of the estimate and if necessary, amends it as appropriate. There could be a significant impact on provision for warranty for any changes of the basis of the estimate.

Provision for unsettled litigation and claims is recognized when it is probable that it will result in an outflow of the Company’s resources and the amount can be reasonably estimated. While the ultimate resolution of litigation and claims cannot be predicted with certainty, the final outcome or the actual cash outflow may be materially different from the estimated liability.

• (2) Impairment of long-term non-financial assets, other than goodwill

In the process of evaluating the potential impairment of tangible and intangible assets other than goodwill, the Company is required to make subjective judgments in determining the independent cash flows, useful lives, expected future income and expenses related to the specific asset groups with the consideration of the nature of industry. Any changes in these estimates based on changed economic conditions or business strategies could result in significant impairment charges or reversal in future years.

39

AU OPTRONICS CORP. AND SUBSIDIARIES

Notes to Consolidated Financial Statements

(3) Impairment of goodwill

The assessment of impairment of goodwill requires the Company to make subjective judgment to determine the identified CGUs, allocate the goodwill to relevant CGUs and estimate the recoverable amount of relevant CGUs.

(4) Measurement of defined benefit obligations

Accrued pension liabilities and the resulting pension expenses under defined benefit pension plans are calculated using the Projected Unit Credit Cost Method. Actuarial assumptions comprise the discount rate, rate of employee turnover, long-term average future salary increase, etc. Changes in economic circumstances and market conditions will affect these assumptions and may have a material impact on the amount of the expense and the liability.

(5) Recognition of deferred tax assets

Deferred tax assets are recognized to the extent that it is probable that future taxable profits will be available against which those deferred tax assets can be utilized. Assessment of the realization of the deferred tax assets requires management’s subjective judgment and estimate, including the future revenue growth and profitability, the sources of taxable income, the amount of tax credits can be utilized and feasible tax planning strategies. Changes in the economic environment, the industry trends and relevant laws and regulations may result in adjustments to the deferred tax assets.

(6) Estimate of allowance for sales returns and discounts

The Company estimates future sales returns and other allowances in the same period the related revenue is recognized. Estimated sales returns and other allowances are generally made and adjusted based on historical experience, management’s judgment and any known factors that would significantly affect the allowance, and management periodically reviews the reasonableness of the estimates.

(7) Valuation of inventories

As inventories are stated at the lower of cost or net realizable value, the Company estimates the net realizable value of inventories for obsolescence and unmarketable items at the end of reporting period and then writes down the cost of inventories to net realizable value. The net realizable value of the inventory is mainly determined based on assumptions of future demand within a specific time horizon. Due to the rapid industrial transformation, there may be significant changes in the net realizable value of inventories.

Notes to Consolidated Financial Statements

The fair value of investment property is based on a valuation performed by a qualified independent appraiser who holds a recognized and relevant professional qualification and has recent valuation experience in the location and category of the investment property being valued. The valuation is performed using income approach, market valuation approach and land development analysis approach with reference to available market information.

Income approach determines the fair value of the investment property based on the projected cash flows from the Company’s estimated future rentals collected and discounted using the capitalization rate of the property. Market valuation approach is through comparison, analysis, adjustment and other means of value for comparable properties to estimate the value of the investment property. Land development analysis approach determine the fair value of investment property based on the value prior to development or construction, after deducting the direct cost, indirect cost, capital interest and profit during the development period, and also consider total sales price of properties after completion of development or construction. It also incorporates the possibility of changes in utility of land through development or improvement in accordance with legal use and density of the land.

The Company’s goodwill has been tested for impairment at least once at the end of the annual reporting period. As at December 31, 2017 and 2016, the recoverable amounts were determined based on value in use of the operating business and its fair value less costs of disposal, respectively. The aforementioned fair value less costs of disposal was calculated based on discounted cash flow forecast with unobservable inputs which categorized within level 3 of fair value measurement.

The key assumptions used in the estimation of the recoverable amount are discount rate and terminal growth rate. The annual discount rates for the year 2017 and 2016 are 11.35% and 11.70%, respectively, based on industry weighted average cost of capital. The cash flow forecast is based on the financial budgets covering the future five-year period with terminal growth rates of negative 1% and 0% for the year 2017 and 2016, respectively. The key assumptions abovementioned represents the management’s forecast of the future for the related industry by considering the history information from internal and external sources.

Based on the impairment assessments for the years ended December 31, 2017 and 2016, no impairment losses were recognized as the recoverable amount of cash-generating unit was higher than its carrying value.

As at December 31, 2017, the weighted-average duration of the defined benefit obligation was between 5 years to 21 years.

(vii) Sensitivity analysis

Reasonably possible changes at December 31, 2017 and 2016 to one of the relevant actuarial assumptions, holding other assumptions constant, would have affected the defined benefit obligation by the amounts shown below.

c. Legal reserve

According to the ROC Company Act, 10 percent of the annual earnings after payment of income taxes due and offsetting accumulated deficits, if any, shall be allocated as legal reserve until the accumulated legal reserve equals the paid-in capital. When a company incurs no loss, it may, pursuant to a resolution to be adopted by a shareholders’ meeting, distribute its legal reserve by issuing new shares or by cash, only the portion of legal reserve which exceeds 25 percent of the paid-in capital may be distributed.

d. Distribution of earnings

In accordance with AUO’s amended Articles of Incorporation approved in the annual shareholders’ meeting held on June 15, 2017, where 10 percent of the annual earnings, after payment of income taxes due and offsetting accumulated deficits, if any, shall be set aside as a legal reserve until the accumulated legal reserve equals AUO’s paid-in capital. In addition, a special reserve in accordance with applicable laws and regulations shall also be set aside. The remaining current-year earnings together with accumulated undistributed earnings from preceding years can be distributed after the earnings distribution plan proposed by the board of directors is approved by resolution of the shareholders’ meeting.

AUO’s dividend policy is to pay dividends from surplus considering factors such as AUO’s current and future investment environment, cash requirements, domestic and overseas competitive conditions and capital budget requirements, while taking into account shareholders’ interest, maintenance of balanced dividend and AUO’s long-term financial plan. If the current-year retained earnings available for distribution reaches 2% of the paid-in capital of AUO, dividend to be distributed shall be no less than 20% of the current-year retained earnings available for distribution. If the current-year retained earnings available for distribution does not reach 2% of the paid-in capital of AUO, AUO may decide not to distribute dividend. The cash portion of the dividend, which may be in the form of cash and stock, shall not be less than 10% of the total dividend distributed during the year. The dividend distribution ratio aforementioned could be adjusted subject to shareholders’ approval in annual shareholders’ meeting after taking into consideration factors such as finance, business and operations, etc.

Pursuant to relevant laws or regulations or as requested by the local authority, total net balance of items which are accounted for as a reduction to the other components of shareholders’ equity shall be set aside from current earnings as special reserve, and not for distribution. Subsequent decrease pertaining to items that are accounted for as a reduction to the other shareholders’ equity shall be reclassified from special reserve to undistributed earnings.

Notes to Consolidated Financial Statements

AUO accrued remuneration to employees based on the profit before income tax excluding the remuneration to employees and directors for each period, multiplied by the percentage resolved by board of directors. For the years ended December 31, 2017 and 2016, AUO estimated the remuneration to employees amounting to $4,062,114 thousand and $1,107,486 thousand, respectively. Remuneration to directors was estimated based on the amount expected to pay and recognized together with the remuneration to employees as cost of sales or operating expenses. If remuneration to employees is resolved to be distributed in stock, the number of shares is determined by dividing the amount of remuneration by the closing price of the shares (ignoring ex-dividend effect) on the day preceding the board of directors’ meeting. If there is a change in the proposed amounts after the annual consolidated financial statements are authorized for issue, the differences are accounted for as a change in accounting estimate and adjusted prospectively to next year’s profit or loss.

Remuneration to employees and directors for 2016 in the amounts of $1,107,486 thousand and $24,226 thousand, respectively, in cash for payment had been approved in the meeting of board of directors held on March 22, 2017. The aforementioned approved amounts are the same as the amounts charged against earnings of 2016.

Remuneration to employees and directors for 2015 in the amounts of $665,815 thousand and $13,316 thousand, respectively, in cash for payment had been approved in the meeting of board of directors held on March 10, 2016. The aforementioned approved amounts are the same as the amounts charged against earnings of 2015.

b. Valuation techniques and assumptions applied in fair value measurement

The fair values of financial assets and financial liabilities with standard terms and conditions and traded in active markets are determined with reference to quoted market prices. The fair vales of other financial assets and financial liabilities without quoted market prices are estimated using valuation approach. The estimates and assumptions used are the same as those used by market participants in the pricing of financial instruments.

Fair value of foreign currency forward contract is measured based on the maturity date of each contract with quoted spot rate and quoted swap points from Reuters quote system. Fair value of interest rate swap contract is measured based on reasonable valuation model and assumptions with reference to market valuation information provided by counterparties, i.e. financial institutions.

Fair value of long-term receivable is determined by discounting the expected cash flows at a market interest rate.

The refundable deposits and guarantee deposits received are based on carrying amount as there is no fixed maturity.

The fair value of floating-rate long-term borrowings approximates to their carrying value.

The Company refers to the quoted spot rates from Reuters quote system for US Dollar’s closing price and other currencies’ buy rates, which has been applied consistently to all periods presented and served as the basis for retranslation of the fair value of abovementioned financial instruments that denominated in foreign currencies.

AU OPTRONICS CORP. AND SUBSIDIARIES

Notes to Consolidated Financial Statements

• c. Fair value measurements recognized in the consolidated balance sheets

The Company determines fair value based on assumptions that market participants would use in pricing an asset or a liability in the principal or most advantageous market. When considering market participant assumptions in fair value measurements, the following fair value hierarchy distinguishes between observable and unobservable inputs, which are categorized in one of the following levels:

• (i) Level 1 inputs: Unadjusted quoted prices for identical assets or liabilities in active markets.

• (ii) Level 2 inputs: Other than quoted prices included within Level 1, inputs are observable for the asset or liability, either directly (i.e. as prices) or indirectly (i.e. derived from prices).

• (iii) Level 3 inputs: Derived from valuation techniques that include inputs for the asset or liability that are not based on observable market data (unobservable inputs).

The fair value measurement level of an asset or a liability within their fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. The Company uses valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs.

(31) Financial Risk Management

• a. Risk management framework

The managerial officers of related divisions are appointed to review, control, trace and monitor the strategic risks, financial risks and operational risks faced by the Company. The managerial officers report to executive officers the progress of risk controls from time to time and, if necessary, report to the board of directors, depending on the extent of impact of risks.

• b. Financial risk information

Hereinafter discloses information about the Company’s exposure to variable risks, and the goals, policies and procedures of the Company’s risk measurement and risk management.

The Company is exposed to the following risks due to usage of financial instruments:

• (i) Credit risk

Credit risk is the risk of financial loss to the Company if a customer or counterparty to a financial instrument fails to meet its contractual obligations. The Company’s exposures to credit risk are mainly from:

• (a) The carrying amount of financial assets recognized in the consolidated balance sheets.

• (b) The amount of contingent liabilities as a result from the Company providing financial guarantee to its customers.

The Company’s potential credit risk is derived primarily from cash in bank, cash equivalents and trade receivables. The Company deposits its cash and cash equivalent investments with various reputable financial institutions of high credit quality. The Company also entered into reverse repurchase agreements with securities firms or banks in Taiwan covering government bonds that classified as cash equivalents. There should be no major concerns for the performance capability of trading counterparts. Management performs periodic evaluations of the relative credit standing of these financial institutions and limits the amount of credit exposure with any one institution. Management believes that there is a limited concentration of credit risk in cash and cash equivalent investments.

79

AU OPTRONICS CORP. AND SUBSIDIARIES

Notes to Consolidated Financial Statements

The majority of the Company’s customers are in high technology industries. Management continuously evaluates and controls the credit quality, credit limit and financial strength of its customers to ensure any overdue receivables are taken necessary procedures. The Company also flexibly makes use of prepayments, accounts receivable factoring and credit insurance as credit enhancement instruments. If necessary, the Company will request collaterals or assurance from its customers in order to reduce the credit risk from particular customers.

Additionally, on the reporting date, the Company reviews the recoverability of its receivables to provide appropriate valuation allowances. Consequently, management believes there is a limited concentration of its credit risk.

For the years ended December 31, 2017 and 2016, the Company’s five largest customers accounted for 39.0% and 36.3%, respectively, of the Company’s consolidated net revenue. There is no other significant concentration of credit risk.

Refer to note 6(5) for aging analysis of accounts receivable and the movement in the allowance of doubtful accounts receivable.

For credit of guarantee, the Company’s policy is to provide financial guarantees only to wholly-owned subsidiaries.

(ii) Liquidity risk

Liquidity risk is the risk that the Company has no sufficient working capital and unused credit facilities to meet its obligations associated with matured financial liabilities, that may resulting from an economic downturn or uneven demand and supply in the market and cause a significant decrease in product selling prices and market demands.

Liquidity risk of the Company is monitored through its corporate treasury department which tracks the development of the actual cash flow position for the Company and uses input from a number of sources in order to forecast the overall liquidity position both on a short and long term basis. Corporate treasury invests surplus cash in money market deposits with appropriate maturities to ensure sufficient liquidity is available to meet liabilities when due, without incurring unacceptable losses or risking damage to the Company’s reputation. As at December 31, 2017, the Company’s working capital together with existing unused credit facilities under its existing loan agreements will be sufficient to fulfill all of its contractual obligations. Therefore, management believes that there is no liquidity risk resulting from incapable of financing to fulfill the contractual obligations.

(iii) Market risk

Market risk is the risk that changes in market prices, such as foreign exchange rates, interest rates and equity prices, which will affect the Company’s income or the value of its holdings of financial instruments. The objective of market risk management is to manage and control market risk exposures within acceptable range, while optimizing the return.

The Company buys and sells derivatives, and also incurs financial liabilities, in order to manage market risks. All such transactions are executed in accordance with the Company’s handling procedures for conducting derivative transactions, and also monitored by internal audit department.

(a) Currency risk

The Company is exposed to currency risk on foreign currency denominated financial assets and liabilities arising from operating, financing and investing activities such that the Company uses forward exchange contracts to hedge its currency risk. Gains and losses derived from the foreign currency fluctuations on underlying assets and liabilities are likely to offset. However, transactions of derivative financial instruments help minimize the impact of foreign currency fluctuations, but the risk cannot be fully eliminated.

The Company periodically examines portions exposed to currency risks for individual asset and liability denominated in foreign currency and uses forward contracts as hedging instruments to hedge positions exposed to risks. The contracts have maturity dates that do not exceed six months, and do not meet the criteria for hedge accounting.

I. Exposure of currency risk

The Company’s significant exposure to foreign currency risk was as follows:

		December 31, 2017	December 31, 2017	December 31, 2017	December 31, 2016	December 31, 2016	December 31, 2016

II. Sensitivity analysis

The Company’s exposure to foreign currency risk arises from the translation of the foreign currency exchange gains and losses on cash and cash equivalents, trade receivables, loans and borrowings and trade payables that are denominated in foreign currency. Depreciation or appreciation of the NTD by 1% against the USD, EUR and JPY at December 31, 2017 and 2016, while all other variables were remained constant, would have increased or decreased the net profit before tax for the years ended December 31, 2017 and 2016 as follows:

1% of depreciation	$	280,968	401,217
1% of appreciation		(280,968)	(401,217)

III. Foreign exchange gain (loss) on monetary items

With varieties of functional currencies within the consolidated entities of the Company, the Company disclosed foreign exchange gain (loss) on monetary items in aggregate. The aggregate of realized and unrealized foreign exchange gains (losses) for the years ended December 31, 2017 and 2016 were $(1,364,929) thousand and $770,325 thousand, respectively.

(b) Interest rate risk

The Company’s exposure to changes in interest rates is mainly from floatingrate long-term debt obligations. Any change in interest rates will cause the effective interest rates of long-term borrowings to change and thus cause the future cash flows to fluctuate over time. The Company enters into and designates interest rate swaps as hedges of the variability in cash flows attributable to interest rate risk.

The following sensitivity analysis is determined based on the exposure to interest rate risk. For floating-rate debts, the analysis assumes that the balances of outstanding debts at the end of the reporting period had been outstanding for the entire year.

For the Company’s floating-rate debts, assuming all other variables were remained constant, an increase or a decrease in the interest rate by 0.25% would have resulted in a decrease or an increase in the net profit before tax for the years ended December 31, 2017 and 2016 by $277,612 thousand and $307,464 thousand, respectively.

(c) Equity price risk

See note 6(3) for disclosure of equity price risk analysis.

• (6) Since December 2006, AUO and certain of its subsidiaries, along with various competitors in the TFT-LCD industry, were under investigation for alleged violation of antitrust and competition laws of certain jurisdictions. Set forth below is a list of the material antitrust proceedings against AUO and certain of its subsidiaries.

United States

In 2012, the Northern California Court rendered judgment against AUO and AUUS regarding the alleged violations of Section 1 of the Sherman Act and imposed a fine of US$500 million against AUO. Such fine was fully paid by AUO as of December 31, 2015. The Northern California Court also placed AUO and AUUS on probation as well as assigned a monitor and required AUO to adopt an effective antitrust compliance program. The probationary period and monitorship ended in December 2016.

Antitrust Civil Actions Lawsuits

There were over 100 civil lawsuits filed against AUO, AUUS and various manufacturers in the TFT-LCD industry in the United States and Canada alleging, among other things, antitrust violations. As of February 6, 2018, AUO and AUUS have reached settlement agreements with the relevant plaintiffs. In addition to the above cases in the United States and Canada, a lawsuit was filed by certain consumers in Israel against certain LCD manufacturers including AUO in the District Court of the Central District in Israel (“Israeli Court”). The defendants contested various issues including whether the lawsuit was properly served. In December 2016, the Israeli Court overturned the original decision and revoked the permission for this case to serve out of Israeli jurisdiction. The plaintiffs lodged an appeal to the Israeli Supreme Court but the Israeli Supreme Court overruled the appeal in August 2017. In January 2018, the parties reached a settlement agreement and agreed to commence the required proceedings for withdrawing the lawsuit.

• (7) In July and August of 2014, SunPower Technology, Ltd. (“SPTL”), AUO and AUSG submitted certain disputes for arbitration in the International Court of Arbitration of the International Chamber of Commerce in San Francisco, U.S. in connection with the joint venture agreement among the parties. The arbitration was amicably settled by the parties in September 2016. AUSG sold all of its shares in the joint venture company AUSP to SPTL at the price of US$170,100 thousand. Please see note 6(8)b. for further details. The shares purchase price shall be paid by SPTL in accordance with the agreement and guaranteed by SunPower Corporation, SPTL’s parent company. The parties have reached amicable agreements regarding the relevant issues, including terminations of the joint venture agreement and relevant agreements and agreed to terminate the arbitration.

• (8) At the end of February 2017, one of AUO’s subsidiaries in the PRC, AUSZ received an administrative complaint filed by Shenzhen China Star Optoelectronics Technology Co., Ltd. (“CSOT”) alleging that AUSZ infringes two PRC patents, and the complaint requests that AUSZ cease the alleged infringing act. Based on the Company’s initial investigation, it believes that its subsidiary does not infringe the two PRC patents as alleged, and further that the two PRC patents appear to be invalid. In response to such administrative complaint, AUSZ has filed a request to invalidate the two PRC patents accordingly. In April 2017, CSOT filed civil lawsuits in the Intermediate People’s Court of Shenzhen Municipality against the subsidiary claiming infringement of the same two PRC patents. In June 2017, CSOT filed civil lawsuits in the No.1 Intermediate People’s Court of Chongqing Municipality against the subsidiary claiming infringement of three PRC patents (including one of the above mentioned PRC patents). CSOT requested that AUSZ ceases the alleged infringing act and claimed approximate RMB49.91 million for economic loss for each of the said respective PRC patents and compensation for reasonable fees and litigation expenses such as notarization fees and attorney fees incurred by CSOT. On September 24, 2017, the relevant parties reached a settlement agreement and agreed to withdraw relevant legal proceedings.

As of February 6, 2018, the Company has made certain provisions with respect to certain of the above lawsuits as the management deems appropriate, considering factors such as the nature of the litigation or claims, the materiality of the amount of possible loss, the progress of the cases and the opinions or views of legal counsel and other advisors. Management will reassess all litigation and claims at each reporting date based on the facts and circumstances that exist at that time, and will make additional provisions or adjustments to previous provisions. The ultimate amount cannot be ascertained until the relevant cases are closed. The ultimate resolution of the legal proceedings and/or lawsuits cannot be predicted with certainty. While management intends to defend certain of the lawsuits described above vigorously, there is a possibility that one or more legal proceedings or lawsuits may result in an unfavorable outcome to the Company. In addition to the matters described above, the Company is also a party to other litigations or proceedings that arise during the ordinary course of business. Except as mentioned above, the Company, to its knowledge, is not involved as a defendant in any material litigation or proceeding which could be expected to have a material adverse effect on the Company’s business or results of operations.

10. Significant Disaster Losses: None.

11. Subsequent Events

FLWJ was resolved by its board of directors for liquidation in October 2012. As of December 31, 2017, the liquidation was still in process. In January 2018, FLMI has received the proceeds of USD7,905 thousand as return of capital from FLWJ.

According to the amendment to the ROC Income Tax Act passed by the Legislature of ROC on January 18, 2018, an increase in the corporate income tax rate from 17% to 20% is applicable upon filing the corporate income tax return starting from fiscal year 2018 onwards. This increase does not affect the amounts of the current and deferred taxes recognized on December 31, 2017. However, this amendment will increase the Company’s current and deferred tax charge accordingly in the future. Assuming the new tax rate is applied in calculating the taxable temporary differences and unused tax losses carryforwards recognized on December 31, 2017,

There have been environmental proceedings relating to the development project of the Central Taiwan Science Park in Houli, Taichung, which AUO’s second 8.5-generation fab is located at and which has been established since 2010. The proceedings were initiated by six residents in Houli District, Taichung City (the “Plaintiffs”) to object the administrative dispositions of the environmental assessment and development approval issued in 2010 by the Environmental Protection Administration (“EPA”) of the Executive Yuan of Taiwan to the third phrase development area in the Central Taiwan Science Park (the “Project”). On August 8, 2014, the Plaintiffs reached a settlement with the defendants (i.e. the governmental authorities, including the EPA of the Executive Yuan of Taiwan, the Ministry of Science and Technology (former National Science Council of the ROC Executive Yuan) and the Central Taiwan Science Park Development Office) in the Taipei High Administrative Court. The second phase environmental impact assessment for the Project continues to proceed. On December 14, 2017, the EPA of the Executive Yuan of Taiwan held the third review meeting of the investigation group. The review meeting reached the conclusion of suggesting approval for the Project. The Central Taiwan Science Park Bureau is now reviewing the comments and conclusion of the review meeting and will reply to the Environmental Impact Assessment Committee of the EPA for further discussion. After approval, the Project will be submitted to the Environmental Impact Assessment General Meeting for review. Currently management does not believe that this event will have a material adverse effect on the Company’s operation and will continue to monitor the development of this event.
