Consolidated Financial Statements for the Three Months Ended March 31, 2018 and 2017 and Independent Auditors’ Review Report

INDEPENDENT AUDITORS’ REVIEW REPORT

The Board of Directors and Stockholders Formosa Sumco Technology Corporation

Introduction

We have reviewed the accompanying consolidated balance sheets of Formosa Sumco Technology Corporation and subsidiaries (the “Company”) as of March 31, 2018 and 2017 and the related consolidated statements of comprehensive income, changes in equity and cash flows for the three months then ended, and related notes, including a summary of significant accounting policies “(collectively referred to as the consolidated financial statements)”. Management is responsible for the preparation and fair presentation of the consolidated financial statements in accordance with the Regulations Governing the Preparation of Financial Reports by Securities Issuers and International Accounting Standard 34 “Interim Financial Reporting. Our responsibility is to express a conclusion on the consolidated financial statements based on our reviews.

Scope of Review

We conducted our reviews in accordance with Statement on Auditing Standards No. 65 “Review of Financial Information Performed by the Independent Auditor of the Entity”. A review of consolidated financial statements consists of making inquiries, primarily of persons responsible for financial and accounting matters, and applying analytical and other review procedures. A review is substantially less in scope than an audit and consequently does not enable us to obtain assurance that we would become aware of all significant matters that might be identified in an audit. Accordingly, we do not express an audit opinion.

Conclusion

Based on our reviews, nothing has come to our attention that caused us to believe that the accompanying consolidated financial statements do not present fairly, in all material respects, of the financial position of the Company as at March 31, 2018 and 2017, and of its consolidated financial performance and its consolidated cash flows for the three months then ended then ended in accordance with the Regulations Governing the Preparation of Financial Reports by Securities Issuers and International Accounting Standard 34 “Interim Financial Reporting”.

2. APPROVAL OF FINANCIAL STATEMENTS

3. APPLICATION OF NEW, AMENDED AND REVISED STANDARDS AND INTERPRETATIONS

a. Initial application of the amendments to the Regulations Governing the Preparation of Financial Reports by Securities Issuers and the International Financial Reporting Standards (IFRS), International Accounting Standards (IAS), Interpretations of IFRS (IFRIC), and Interpretations of IAS (SIC) (collectively, the “IFRSs”) endorsed and issued into effect by the Financial Supervisory Commission (FSC)

Except for the following, whenever applied, the initial application of the amendments to the Regulations Governing the Preparation of Financial Reports by Securities Issuers and the IFRSs endorsed and issued into effect by the FSC would not have any material impact on the Group’s accounting policies:

1) IFRS 9 “Financial Instruments” and related amendment

IFRS 9 “Financial Instruments” supersedes IAS 39 “Financial Instruments: Recognition and Measurement”, with consequential amendments to IFRS 7 “Financial Instruments: Disclosures”

10 -

and other standards. IFRS 9 sets out the requirements for classification, measurement and impairment of financial assets and hedge accounting. Refer to Note 4 for information relating to the relevant accounting policies.

Classification, measurement and impairment of financial assets

On the basis of the facts and circumstances that existed as at January 1, 2018, the Group has performed an assessment of the classification of recognized financial assets and has elected not to restate prior reporting periods.

The following table shows the original measurement categories and carrying amount under IAS 39 and the new measurement categories and carrying amount under IFRS 9 for each class of the Group’s financial assets and financial liabilities as at January 1, 2018.

		Measurement Category	Measurement Category	Measurement Category	Measurement Category			Carrying	Carrying	Amount	Amount

a) The Group elected to designated all its investments in equity securities previously classified as available-for-sale under IAS 39 as at FVTOCI under IFRS 9, because these investments are not held for trading. As a result, the related other equity - unrealized gain (loss) on available-for-sale financial assets of $337 thousand was reclassified to other equity - unrealized gain (loss) on financial assets at FVTOCI.
b) Trade receivables and other receivables that were previously classified as loans and receivables under IAS 39 were classified as measured at amortized cost with an assessment of expected credit losses under IFRS 9. As a result of retrospective application, the adjustments had no difference on January 1, 2018.
2) IFRS 15 “Revenue from Contracts with Customers” and related amendment

IFRS 15 establishes principles for recognizing revenue that apply to all contracts with customers, and supersedes IAS 18 “Revenue”, IAS 11 “Construction Contracts” and a number of revenue-related interpretations.

11 -

IFRS 15 require that a good or service is distinct if it is capable of being distinct, for the sales of products by the Group, there should be no service provision. There is no transactions with goods and services being integrated, while there are no authorised trade and other transactions within the Group. Hence, IFRS 15 and its related amendments have no material impact on the Group.

Note 4: The Group shall apply these amendments to plan amendments, curtailments or settlements occurring on or after January 1, 2019.

IFRS 16 “Leases”

IFRS 16 sets out the accounting standards for leases that will supersede IAS 17 and a number of related interpretations.

Under IFRS 16, if the Group is a lessee, it shall recognize right-of-use assets and lease liabilities for all leases on the consolidated balance sheets except for low-value and short-term leases. The Group may elect to apply the accounting method similar to the accounting for operating leases under IAS 17 to low-value and short-term leases. On the consolidated statements of comprehensive income, the Group should present the depreciation expense charged on right-of-use assets separately from the interest expense accrued on lease liabilities; interest is computed by using the effective interest method. On the consolidated statements of cash flows, cash payments for the principal portion of lease liabilities are classified within financing activities; cash payments for the interest portion are classified within operating activities.

The application of IFRS 16 is not expected to have a material impact on the accounting of the Group as lessor.

When IFRS 16 becomes effective, the Group may elect to apply this standard either retrospectively to each prior reporting period presented or retrospectively with the cumulative effect of the initial application of this standard recognized at the date of initial application.

12 -

Except for the above impact, as of the date the consolidated financial statements were authorized for issue, the Group is continuously assessing the possible impact that the application of other standards and interpretations will have on the Group’s financial position and financial performance, and will disclose the relevant impact when the assessment is completed.

4. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

a. Statement of compliance

These interim consolidated financial statements have been prepared in accordance with the Regulations Governing the Preparation of Financial Reports by Securities Issuers and IAS 34 “Interim Financial Reporting” as endorsed and issued into effect by the FSC. Disclosure information included in these interim consolidated financial statements is less than the disclosure information required in a complete set of annual financial statements.

b. Basis of preparation

The consolidated financial statements have been prepared on the historical cost basis except for financial instruments which are measured at fair value and net defined benefit liabilities which are valued by the present value of defined benefit minus fair value of assets.

The fair value measurements, which are grouped into Levels 1 to 3 based on the degree to which the fair value measurement inputs are observable and based on the significance of the inputs to the fair value measurement in its entirety, are described as follows:

1) Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities;
2) Level 2 inputs are inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly (i.e. as prices) or indirectly (i.e. derived from prices); and
3) Level 3 inputs are unobservable inputs for the asset or liability.
c. Basis of consolidation

See Note 10 and Table 6 for the detailed information of subsidiaries (including the percentage of ownership and main business).

d. Other significant accounting policies

Except for the following, the accounting policies applied in these consolidated financial statements are consistent with those applied in the consolidated financial statements for the year ended December 31, 2017. For the summary of other significant accounting policies, please refer to the consolidated financial statements for the year ended December 31, 2017.

1) Financial instruments

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

Financial assets and financial liabilities are initially measured at fair value. Transaction costs that are directly attributable to the acquisition or issue of financial assets and financial liabilities (other than financial assets and financial liabilities at FVTPL) are added to or deducted from the fair value of the financial assets or financial liabilities, as appropriate, on initial recognition. Transaction costs directly attributable to the acquisition of financial assets or financial liabilities at FVTPL are recognized immediately in profit or loss.

13 -
a) Financial assets

All regular way purchases or sales of financial assets are recognized and derecognized on a trade date basis.

i. Measurement category

2018

Financial assets are classified into the following categories: Financial assets at amortized cost and investments equity instruments at FVTOCI.

i) Financial assets at amortized cost

Financial assets that meet the following conditions are subsequently measured at amortized cost:

The financial asset is held within a business model whose objective is to hold financial assets in order to collect contractual cash flows; and
The contractual terms of the financial asset give rise on specified dates to cash flows that are solely payments of principal and interest on the principal amount outstanding.

Subsequent to initial recognition, financial assets at amortized cost, including cash and cash equivalents, trade receivables at amortized cost, other receivables and refundable deposits, are measured at amortized cost, which equals to gross carrying amount determined by the effective interest method less any impairment loss. Exchange differences are recognized in profit or loss.

Interest income is calculated by applying the effective interest rate to the gross carrying amount of a financial asset, except for:

Purchased or originated credit-impaired financial asset, for which interest income is calculated by applying the credit-adjusted effective interest rate to the amortized cost of the financial asset; and
Financial asset that has subsequently become credit-impaired, for which interest income is calculated by applying the effective interest rate to the amortized cost of the financial asset.

Cash equivalents include time deposits, commercial papers and repurchase agreements collateralized by bonds with original maturities within 3 months from the date of acquisition, which are highly liquid, readily convertible to a known amount of cash and are subject to an insignificant risk of changes in value. These cash equivalents are held for the purpose of meeting short-term cash commitments.

ii) Investments in equity instruments at FVTOCI

On initial recognition, the Group may make an irrevocable election to designate investments in equity instruments as at FVTOCI. Designation at FVTOCI is not permitted if the equity investment is held for trading or if it is contingent consideration recognized by an acquirer in a business combination.

14 -

Investments in equity instruments at FVTOCI are subsequently measured at fair value with gains and losses arising from changes in fair value recognized in other comprehensive income and accumulated in other equity. The cumulative gain or loss will not be reclassified to profit or loss on disposal of the equity investments, instead, they will be transferred to retained earnings.

Dividends on these investments in equity instruments are recognized in profit or loss when the Group’s right to receive the dividends is established, unless the dividends clearly represent a recovery of part of the cost of the investment.

2017

Financial assets are classified into the following categories: Available-for-sale financial assets and loans and receivables.

i) Available-for-sale financial assets

Available-for-sale financial assets are non-derivatives that are either designated as available-for-sale or are not classified as loans and receivables, held-to-maturity investments or financial assets at fair value through profit or loss.

Available-for-sale financial assets are measured at fair value. Changes in the carrying amounts of available-for-sale monetary financial assets (relating to changes in dividends on available-for-sale equity investments) are recognized in profit or loss. Other changes in the carrying amount of available-for-sale financial assets are recognized in other comprehensive income and will be reclassified to profit or loss when such investments are disposed of or are determined to be impaired.

Dividends on available-for-sale equity instruments are recognized in profit or loss when the Group’s right to receive the dividends is established.

ii) Loans and receivables

Loans and receivables (including trade receivables, cash and cash equivalent, debt investments with no active market, and other receivables) are measured using the effective interest method at amortized cost, less any impairment, except for short-term receivables when the effect of discounting is immaterial.

Cash equivalents include repurchase agreements collateralized by bonds, commercial papers and time deposits with original maturities within 3 months from the date of acquisition, which are highly liquid, readily convertible to a known amount of cash and are subject to an insignificant risk of changes in value. These cash equivalents are held for the purpose of meeting short-term cash commitments.

ii. Impairment of financial assets

2018

The Group recognizes a loss allowance for expected credit losses on financial assets at amortized cost (including trade receivables).

The Group always recognizes lifetime Expected Credit Loss (i.e. ECL) for trade receivables. For all other financial instruments, the Group recognizes lifetime ECL when there has been a significant increase in credit risk since initial recognition. If, on the other hand, the credit risk on the financial instrument has not increased significantly since initial recognition, the

15 -

Group measures the loss allowance for that financial instrument at an amount equal to 12-month ECL.

Expected credit losses reflect the weighted average of credit losses with the respective risks of a default occurring as the weights. Lifetime ECL represents the expected credit losses that will result from all possible default events over the expected life of a financial instrument. In contrast, 12-month ECL represents the portion of lifetime ECL that is expected to result from default events on a financial instrument that are possible within 12 months after the reporting date.

The Group recognizes an impairment gain or loss in profit or loss for all financial instruments with a corresponding adjustment to their carrying amount through a loss allowance account.

2017

Financial assets, other than those at fair value through profit or loss, are assessed for indicators of impairment at the end of each reporting period. Financial assets are considered to be impaired when there is objective evidence, as a result of one or more events that occurred after the initial recognition of the financial asset, the estimated future cash flows of the investment have been affected.

For financial assets carried at amortized cost, such as trade receivables, such assets are assessed for impairment on a collective basis even if they were assessed not to be impaired individually. Objective evidence of impairment for a portfolio of receivables could include the Group’s past experience of collecting payments and an increase in the number of delayed payments in the portfolio past the average credit period.

For financial assets carried at amortized cost, the amount of the impairment loss recognized is the difference between the asset’s carrying amount and the present value of estimated future cash flows, discounted at the financial asset’s original effective interest rate.

For financial assets measured at amortized cost, if, in a subsequent period, the amount of the impairment loss decreases and the decrease can be related objectively to an event occurring after the impairment was recognized, the previously recognized impairment loss is reversed through profit or loss to the extent that the carrying amount of the investment at the date the impairment is reversed does not exceed what the amortized cost would have been had the impairment not been recognized.

For available-for-sale equity investments, a significant or prolonged decline in the fair value of the security below its cost is considered to be objective evidence of impairment.

For all other financial assets, objective evidence of impairment could include significant financial difficulty of the issuer or counterparty, breach of contract, such as a default or delinquency in interest or principal payments, it becoming probable that the borrower will enter bankruptcy or financial re-organization, or the disappearance of an active market for that financial asset because of financial difficulties.

When an available-for-sale financial asset is considered to be impaired, cumulative gains or losses previously recognized in other comprehensive income are reclassified to profit or loss in the period.

16 -

In respect of available-for-sale equity securities, impairment loss previously recognized in profit or loss are not reversed through profit or loss. Any increase in fair value subsequent to an impairment loss is recognized in other comprehensive income. In respect of available-for-sale debt securities, the impairment loss is subsequently reversed through profit or loss if an increase in the fair value of the investment can be objectively related to an event occurring after the recognition of the impairment loss.

The carrying amount of the financial asset is reduced by the impairment loss directly for all financial assets with the exception of trade receivables where the carrying amount is reduced through the use of an allowance account. When trade receivables are considered uncollectible, they are written off against the allowance account. Subsequent recoveries of amounts previously written off are credited against the allowance account. Changes in the carrying amount of the allowance account are recognized in profit or loss except for uncollectible trade receivables that are written off against the allowance account.

iii. Derecognition of financial assets

The Group derecognizes a financial asset only when the contractual rights to the cash flows from the asset expire or when it transfers the financial asset and substantially all the risks and rewards of ownership of the asset to another party.

Before 2018, on derecognition of a financial asset in its entirety, the difference between the asset’s carrying amount and the sum of the consideration received and receivable and the cumulative gain or loss that had been recognized in other comprehensive income is recognized in profit or loss. From 2018, on derecognition of a financial asset at amortized cost in its entirety, the difference between the asset’s carrying amount and the sum of the consideration received and receivable is recognized in profit or loss. On derecognition of an investment in an equity instrument at FVTOCI, the difference between the asset’s carrying amount and the sum of the consideration received and receivable is recognized in profit or loss, and the cumulative gain or loss that had been recognized in other comprehensive income is transferred directly to retained earnings, without recycling through profit or loss.

b) Equity instruments

Debt and equity instruments issued by a group entity are classified as either financial liabilities or as equity in accordance with the substance of the contractual arrangements and the definitions of a financial liability and an equity instrument.

Equity instruments issued by a group entity are recognized at the proceeds received, net of direct issue costs.

Repurchase of the Company’s own equity instruments is recognized in and deducted directly from equity. No gain or loss is recognized in profit or loss on the purchase, sale, issue or cancellation of the Company’s own equity instruments.

c) Financial liabilities

i. Subsequent measurement

All financial liabilities are measured at amortized cost using the effective interest method.

ii. Derecognition of financial liabilities
17 -

The difference between the carrying amount of the financial liability derecognized and the consideration paid, including any non-cash assets transferred or liabilities assumed, is recognized in profit or loss.

2) Revenue recognition

2018

The Group identifies the contract with the customers, allocates the transaction price to the performance obligations, and recognizes revenue when performance obligations are satisfied.

a) Revenue from sale of goods

Revenue from sale of goods comes from sales of silicon wafer. Sales of silicon wafer are recognized as revenue when the goods are delivered to the customer’s specific location and the goods are actually used because it is the time when the customer has full discretion over the manner of distribution and price to sell the goods, has the primary responsibility for sales to future customers, and bears the risks of obsolescence. Trade receivable is recognized co-currently.

b) Revenue from rendering of services

Revenue from rendering of services comes from consignment. The Group is an agent and its performance obligation is to consignment. The Group recognizes revenue in the net amount of consideration received or receivable when the goods that are consignmented are transferred to the customer and the Group has no further obligation to the customer.

2017

Revenue is measured at the fair value of the consideration received or receivable. Revenue is reduced for estimated customer returns, rebates and other similar allowances.

a) Sale of goods

Revenue from the sale of goods is recognized when all the following conditions are satisfied:

i. The Group has transferred to the buyer the significant risks and rewards of ownership of the goods;
ii. The Group retains neither continuing managerial involvement to the degree usually associated with ownership nor effective control over the goods sold;
iii. The amount of revenue can be measured reliably;
iv. It is probable that the economic benefits associated with the transaction will flow to the Group; and
v. The costs incurred or to be incurred in respect of the transaction can be measured reliably.
b) Rendering of services

Service income (including that from operating service provided under service concession arrangements) is recognized when services are provided.

c) Dividend and interest income
18 -

Dividend income from investments is recognized when the shareholder’s right to receive payment has been established provided that it is probable that the economic benefits will flow to the Group and the amount of income can be measured reliably.

Interest income from a financial asset is recognized when it is probable that the economic benefits will flow to the Group and the amount of income can be measured reliably. Interest income is accrued on a time basis, by reference to the principal outstanding and at the applicable effective interest rate.

3) Retirement benefit plan

Pension cost for an interim period is calculated on a year-to-date basis by using the actuarially determined pension cost rate at the end of the prior financial year, adjusted for significant market fluctuations since that time and for significant plan amendments, settlements, or other significant one-off events.

4) Taxation

Income tax expense represents the sum of the tax currently payable and deferred tax. Interim period income taxes are assessed on an annual basis and calculated by applying to an interim period’s pre-tax income the tax rate that would be applicable to expected total annual earnings. The effect of a change in tax rate resulting from a change in tax law is recognized consistent with the accounting for the transaction itself which gives rise to the tax consequence, and is recognized in profit or loss, other comprehensive income or directly in equity in full in the period in which the change in tax rate occurs.

Trade Receivables

For the three months ended March 31, 2018

In order to minimize credit risk, the management of the Company has delegated a team responsible for determining credit limits, credit approvals and other monitoring procedures to ensure that follow-up action is taken to recover overdue debts. In addition, the Group reviews the recoverable amount of each individual trade debt at the end of the reporting period to ensure that adequate allowance is made for possible irrecoverable amounts. In this regard, the management believes the Group’s credit risk was significantly reduced.

The Group applies the simplified approach to providing for expected credit losses prescribed by IFRS 9, which permits the use of lifetime expected loss provision for all trade receivables. The expected credit losses on trade receivables are estimated using a provision matrix by reference to past default experience of the debtor and an analysis of the debtor’s current financial position, adjusted for general economic conditions of the industry in which the debtors operate and an assessment of both the current as well as the forecast direction of economic conditions at the reporting date. As the Group’s historical credit loss experience does not show significantly different loss patterns for different customer segments, the provision for loss allowance based on past due status is not further distinguished according to the Group’s different customer base.

The Group writes off a trade receivable when there is information indicating that the debtor is in severe financial difficulty and there is no realistic prospect of recovery. For trade receivables that have been written off, the Group continues to engage in enforcement activity to attempt to recover the receivables due. Where recoveries are made, these are recognized in profit or loss.

The following table details the loss allowance of trade receivables based on the Group’s provision matrix.

March 31, 2018

21 -

For the three months ended March 31, 2017

The average credit period on sales of goods was 30-90 days. In determining the recoverability of a trade receivable, the Group considered any change in the credit quality of the trade receivable since the date credit was initially granted to the end of the reporting period. The Group recognized an allowance for impairment loss of 100% against all receivables overdue 180 days because historical experience had been that receivables that are past due beyond 180 days were not recoverable. Allowance for impairment loss were recognized against trade receivables between 1 day and 180 days based on estimated irrecoverable amounts determined by reference to past default experience of the counterparties and an analysis of their current financial position.

The aging of trade receivables was as follows:

0-30 days 31-60 days 61-90 days 91-120 days		December 31	December 31
		2017 $ 1,095,011 666,967 357,485 9,313 $ 2,128,776	2016 $ 1,021,427 469,074 160,222 - $ 1,650,723

The above aging schedule was based on past due days from invoice date.

There are no receivables that were past due but not impaired as of December 31, 2017 and 2016.

d. Financial risk management objectives and policies

The Group’s major financial instruments include equity investments, trade receivables, trade payables, and bank borrowings. The Group’s Corporate Treasury function provides services to the business, coordinates access to domestic and international financial markets, monitors and manages the financial risks relating to the operations of the Group through internal risk reports which analyze exposures by degree and magnitude of risks. These risks include market risk (including currency risk, interest rate risk and other price risk), credit risk and liquidity risk.

1) Market risk

The Group’s activities exposed it primarily to the financial risks of changes in foreign currency exchange rates (see (a) below) and interest rates (see (b) below).

There had been no change to the Group’s exposure to market risks or the manner in which these risks were managed and measured.

a) Foreign currency risk

The Group had foreign currency sales and purchases, which exposed the Group to foreign currency risk.

The carrying amounts of the Group’s foreign currency denominated monetary assets and monetary liabilities at the end of the reporting period are set out in Note 24.

Sensitivity analysis

The Group was mainly exposed to the U.S. dollars (USD) and Japanese Yen (JPY).

The following table details the Group’s sensitivity to a 10% increase and decrease in NTD (the functional currency) against the relevant foreign currencies. 10% is the sensitivity rate used when reporting foreign currency risk internally to key management personnel and represents management’s assessment of the reasonably possible change in foreign exchange rates. The sensitivity analysis included only outstanding foreign currency denominated monetary items and adjusts their translation at the end of the reporting period for a 10% change in foreign currency rates. A positive number below indicates an increase in pre-tax profit associated with NTD weakening 10% against the relevant currency. For a 10% strengthening of NTD against the relevant currency, there would be an equal and opposite impact on pre-tax profit and the balances below would be negative.

Profit or loss	USD Impact For the Three Months Ended March 31 2018 2017 $ 325,528 (i) $ 220,632 (i)	JPY Impact
		For the Three Months Ended March 31
		2018 2017 $ (27,592) (ii) $ (35,976) (ii)

34 -
i) This was mainly attributable to the exposure outstanding on USD cash and cash equivalents, trade receivables and trade payables, which were not hedged at the end of the reporting period.
ii) This was mainly attributable to the exposure to outstanding on JPY cash and cash equivalents, trade receivables, and trade payables, which were not hedged, at the end of the reporting period.

The Group’s sensitivity to foreign currency increased during the current year mainly due to the increase of USD bank deposits and trade receivables.

b) Interest rate risk

The carrying amount of the Group’s financial assets and financial liabilities with exposure to interest rates at the end of the reporting period were as follows:

		December 31,
	March 31, 2018	2017	March 31, 2017
Fair value interest rate risk
Financial assets	$ 7,136,254	$ 6,819,038	$ 4,287,966
Cash flow interest rate risk
Financial assets	697,645	789,880	651,479

Sensitivity analysis

The sensitivity analyses below were determined based on the Group’s exposure to interest rates for non-derivative instruments at the end of the reporting period. For floating rate liabilities, the analysis was prepared assuming the amount of the liability outstanding at the end of the reporting period was outstanding for the whole year. A 1% increase or decrease was used when reporting interest rate risk internally to key management personnel and represents management’s assessment of the reasonably possible change in interest rates.

If interest rates had been 1% higher/lower and all other variables were held constant, the Group’s pre-tax profit for the 3 months ended March 31, 2018 would increase/decrease by $1,744 thousand, respectively, which was mainly attributable to the Group’s exposure to interest rates on floating rate bank deposits.

If interest rates had been 1% higher/lower and all other variables were held constant, the Group’s pre-tax profit for the 3 months ended March 31, 2017 would increase/decrease by $1,629 thousand, respectively, which was mainly attributable to the Group’s exposure to interest rates on floating rate bank deposits.

The Group’s sensitivity to interest rates has no major difference for the 3 months ended March 31, 2018 and 2017.

2) Credit risk

Credit risk refers to the risk that a counterparty will default on its contractual obligations resulting in financial loss to the Group. The Group’s key exposure to credit risk is primarily the trade receivables arise from operating activities.

35 -

In order to minimize credit risk, management of the Group has delegated a team responsible for determining credit limits, credit approvals and other monitoring procedures to ensure that follow-up action is taken to recover overdue debts. In addition, the Group reviews the recoverable amount of each individual trade debt at the end of the reporting period to ensure that adequate allowances are made for irrecoverable amounts. In this regard, management believes the Group’s credit risk was significantly reduced.

The Group did not have significant credit risk exposure to any single counterparty or any group of counterparties having similar characteristics, except for the clients with trade receivables accounting for 10% of total monetary assets. The Group defines counterparties as having similar characteristics if they are related entities. The receivables from any other counterparty did not exceed 10% of total monetary assets at any time during the 3 months ended March 31, 2018, the year ended December 31, 2017, and the 3 months ended March 31, 2017.

3) Liquidity risk

The Group manages liquidity risk by monitoring and maintaining a level of cash and cash equivalents, highly liquid marketable securities, and sufficient bank borrowings deemed adequate to finance the Group’s operations and mitigate the effects of fluctuations in cash flows.

Liquidity and interest risk rate table

The following table details the Group’s remaining contractual maturity for its non-derivative financial liabilities with agreed repayment periods. The tables had been drawn up based on the undiscounted cash flows of financial liabilities from the earliest date on which the Group can be required to pay. The tables included both interest and principal cash flows.

To the extent that interest flows are floating rate, the undiscounted amount was derived from the interest rate at the end of the reporting period.

The following table details the Group’s expected maturity for some of its non-derivative financial assets. The tables below had been drawn up based on the undiscounted contractual maturities of the financial assets including interest that will be earned on those assets. The inclusion of information on non-derivative financial assets is necessary in order to understand the Group’s liquidity risk management as the liquidity is managed on a net asset and liability basis.
