AUDITOR’S REPORT Limited

To the Shareholders of Eastern Water Resources Development and Management Public Company

I have audited the accompanying consolidated and company balance sheet as at 31 December 2010, and the related consolidated and company statements of income, changes in shareholders’ equity and cash flows for the year then ended of Eastern Water Resources Development and Management Public Company Limited and its subsidiaries and of Eastern Water Resources Development and Management Public Company Limited, respectively. The Company’s management is responsible for the correctness and completeness of information in these financial statements. My responsibility is to express an opinion on these financial statements based on my audit. The consolidated and company financial statements for the year end, 31 December 2009, of Eastern Water Resources Development and Management Public Company Limited and its subsidiaries and of Eastern Water Resources Development and Management Public Company Limited, respectively, were audited by another auditor whose report dated 15 February 2010, expressed an unqualified opinion on those statements and drew attention to two matters regarding 1) a pipeline connection project for which the Company undertook construction and made advance payments on behalf of a government agency amounting to Baht 646.5 million. Subsequently, the Company and the government agency signed a sale and purchase agreement of such assets. 2) the compensation of the Company’s pipeline connecting project, the Company paid the compensation at a preliminary rate but this may change. The government agency was considering a deal for the Company to rent/ manage the project and to adjust the compensation rate. A resolution has not yet been reached. I conducted my audit in accordance with generally accepted auditing standards. Those standards require that I plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. I believe that my audit provides a reasonable basis for my opinion. In my opinion, the consolidated and company financial statements referred to above present fairly, in all material respects, the consolidated and company financial position as at 31 December 2010, and the consolidated and company results of operations, and cash flows for the year then ended of Eastern Water Resources Development and Management Public Company Limited and its subsidiaries and of Eastern Water Resources Development and Management Public Company Limited, respectively, in accordance with generally accepted accounting principles. Without qualifying my opinion on the aforementioned financial statements, I draw attention to Note 30.5 to the financial statements regarding the compensation of the Company’s pipeline connecting project. The Company is paying the compensation at a preliminary rate because the government agency is considering a deal for the Company to rent/manage the connecting projects and the compensation rate that may change.

New accounting standards, new financial reporting standards, new interpretation, amendments to accounting standards, accounting framework and termination of standard a) Accounting framework The amendment of accounting framework is effective on 26 May 2010. b) New accounting standards, new financial reporting standards, new interpretation and amendments to accounting standards The following new accounting standards, new financial reporting standards, new interpretation and amendments to accounting standards are mandatory for the accounting periods beginning on or after 1 January 2011 and 1 January 2013:

Effective for the periods beginning on or after 1 January 2011 TAS 1 (Revised 2009) Presentation of Financial Statements TAS 2 (Revised 2009) Inventories TAS 7 (Revised 2009) Statement of Cash Flows TAS 8 (Revised 2009) Accounting Policies, Changes in Accounting Estimates and Errors TAS 10 (Revised 2009) Events after the Reporting Period TAS 11 (Revised 2009) Construction Contracts TAS 16 (Revised 2009) Property, Plant and Equipment TAS 17 (Revised 2009) Leases TAS 18 (Revised 2009) Revenue TAS 19 Employee Benefits TAS 23 (Revised 2009) Borrowing Costs TAS 24 (Revised 2009) Related Party Disclosures TAS 26 Accounting and Reporting by Retirement Benefit Plans TAS 27 (Revised 2009) Consolidated and Separate Financial Statements TAS 28 (Revised 2009) Investments in Associates TAS 29 Financial Reporting in Hyperinflationary Economies TAS 31 (Revised 2009) Interests in Joint Ventures TAS 33 (Revised 2009) Earnings per Share TAS 34 (Revised 2009) Interim Financial Reporting TAS 36 (Revised 2009) Impairment of Assets TAS 37 (Revised 2009) Provisions, Contingent Liabilities and Contingent Assets TAS 38 (Revised 2009) Intangible Assets TAS 40 (Revised 2009) Investment Property TFRS 2 Share-based Payment TFRS 3 (Revised 2009) Business Combinations TFRS 5 (Revised 2009) Non-current Assets Held for Sale and Discontinued Operations TFRS 6 Exploration for and Evaluation of Mineral Resources TFRIC 15 Agreements for the Construction of Real Estate Effective for the periods beginning on or after 1 January 2013 TAS 12 Income taxes TAS 20 (Revised 2009) Accounting for Government Grants and Disclosure of Government Assistance TAS 21 (Revised 2009) The Effects of Changes in Foreign Exchange Rates

The Companyâ&#x20AC;&#x2122;s management has determined that the new accounting standards, new financial reporting standards, new interpretation and amendments to accounting standards will have impact to the financial statements as follows: TAS 1 (Revised 2009), the revised standard will prohibit the presentation of items of income and expenses in the statement of changes in equity. Entities can choose whether to present one statement (the statement of comprehensive income) or two statements (the income statement and statement of comprehensive income). Where entities restate or reclassify comparative information, they will be required to present a restated statement of financial position as at the beginning comparative period in addition to the current requirement to present statement of financial position at the end of the current period and comparative period. However, for the financial statements which period beginning on or after 1 January 2011 and are the first period apply this standard, an entity can choose to present statement of financial position only two statements without the statement of financial position as at the beginning comparative period. The group will apply TAS 1 (Revised 2009) from 1 January 2011. It is likely that both income statement and statement of comprehensive income will be presented as one statement. TAS 12 deals with taxes on income, comprising current tax and deferred tax. Current tax assets and liabilities are measured at the amount expected to be recovered from or be paid to the taxation authorities, using tax rates and tax law that have been enacted or substantively enacted by the end of the reporting period. Deferred taxes are measured by based on the temporary difference between the tax base of an asset or liability and its carrying amount in the financial statements and using the tax rates that are expected to apply to the period when the asset is realised or the liability is settled, based on tax rates and tax law that have been enacted or substantively enacted by the end of the reporting period. The group will early adopted this standard from 1 January 2011 retrospectively with an expectation to have impact to financial statements as at 1 January 2011 as follows:

Deferred tax assets increase Deferred tax liabilities increase Retained earnings increase (decrease)

Consolidated Million Baht 30.61 43.47 (12.86)

Company Million Baht 17.61 0.31 17.30

TAS 16 (Revised 2009), the revised standard requires the entity to include in cost of PPE, an initial estimate of the costs of dismantling and removing the item and restoring the site on which it is located, when the entity has obligation to do. An entity requires that an item of property, plant and equipment with a cost that is significant in relation to the total cost of the item shall be depreciated separately. The revised standard also requires an entity to review useful life, residual value and depreciation method at least at each financial year-end. The group will apply this standard from 1 January 2011 which has no impact to retained earnings as at 1 January 2011. TAS 19 deal with accounting for employee benefit. The standard classifies employee benefit into 4 categories: a) short-term employee benefits b) post-employment benefits (including defined contribution plan and defined benefit plan) c) other long-term employee benefits and d) termination benefits. The standard requires the entity to measure the defined benefit plan and other long-term employee benefits by using the Projected Unit Credit method (PUC). An entity can choose to recognise any actuarial gain or loss for defined benefit plan either in other comprehensive income or profit and loss. Actuarial gain or loss for other long-term employee benefit shall recognise in profit and loss. The group will apply this standard from 1 January 2011 which has impact to financial statements by decrease in retained earnings and increase in retirement benefit obligations as at 1 January 2011 in consolidated financial statements and company financial statements amounting to Baht 56.98 million and Baht 33.94 million, respectively. TAS 23 (Revised 2009), the revised standard requires an entity to capitalise borrowing costs directly attributable to the acquisition, construction or production of a qualifying asset as part of the cost of that asset. The option of immediately expensing those borrowing costs will be removed. The group will apply prospectively from 1 January 2011 but it is not expected to have any impact on the groupâ&#x20AC;&#x2122;s financial statement because the group already apply capitalised model.

TAS 24 (Revised 2009), the definition of related party has been expanded include parties with joint control over the entity, joint venture in which the entity is a venturer and postemployment benefit plan for the benefit of employees of an entity. The group will apply the revised standard from 1 January 2011 which may impact only to the disclosure of related parties information in the notes to the financial statements. TAS 40 (Revised 2009), the standard has specific presentation and measurement requirements for investment property. The entity has to present an investment property separately in the statement of financial position. The entity can choose to measure it either cost model or fair value model. Under fair value model, any changes in fair value are recognised in profit or loss. The entity will apply the standard from 1 January 2011. The group will apply cost model for measurement and disclose fair value in the notes to the financial statements.

2.3

Change in accounting estimate During the first quarter 2010, the Company changed its accounting estimation for calculating depreciation of the raw water pipeline systems from units of production method which were computed from estimated volume of units sales and not exceeding the production capacity of the assets over 40 years to straight-line method over their remaining estimated useful lives of 34 - 37 years. The Companyâ&#x20AC;&#x2122;s management considered that the straight-line method is more appropriate because those assets are depreciated over the time being used. The changes in accounting estimation shall be recognised prospectively. The effects of the changes in depreciation method result to an increased in depreciation expense for the year ended 31 December 2010 by Baht 60.13 million and net profit before tax decreased by the same amount.

2.4

Group Accounting - Investment in subsidiaries Subsidiaries are all entities (including special purpose entities) over which the Group has the power to govern the financial and operating policies generally accompanying a shareholding of more than one half of the voting rights. The existence and effect of potential voting rights that are currently exercisable or convertible, including potential voting rights held by another entity, are considered when assessing whether the Group controls another entity. Subsidiaries are consolidated from the date on which control is transferred to the Group and are no longer consolidated from the date that control ceases.

The purchase method of accounting is used to account for the acquisition of subsidiaries by the Group. The cost of an acquisition is measured as the fair value of the assets given, equity instruments issued and liabilities incurred or assumed at the date of exchange, plus costs directly attributable to the acquisition. Identifiable assets acquired and liabilities and contingent liabilities assumed in a business combination are measured initially at their fair values at the acquisition date, irrespective of the extent of any minority interest. The excess of the cost of acquisition over the fair value of the Groupâ&#x20AC;&#x2122;s share of the identifiable net assets acquired is recorded as goodwill. If the cost of acquisition is less than the fair value of the net assets of the subsidiary acquired, the difference is recognised directly in the income statement. Inter-company transactions, balances and unrealised gains on transactions between group companies are eliminated; unrealised losses are also eliminated unless cost cannot be recovered. Where necessary, accounting policies of the Group have been changed to ensure consistency with the policies adopted by the Company. In the Companyâ&#x20AC;&#x2122;s separate financial statements investments in subsidiaries are reported by using the cost less allowance for impairment (if any). A list of the Groupâ&#x20AC;&#x2122;s principal subsidiaries is set out in Note 12.

2.5

Foreign currency translation Items included in the financial statements of each entity in the Group are measured using Thai Baht. The consolidated financial statements are presented in Thai Baht. Foreign currency transactions are translated into Thai Baht using the exchange rates prevailing at the date of the transaction. Monetary assets and liabilities denominated in foreign currency are translated to Thai Baht at the exchange rate prevailing at the balance sheet date. Gains and losses resulting from the settlement of foreign currency transactions and from the translation of monetary assets and liabilities denominated in foreign currencies, are recognised in the statement of income.

2.6

Cash and cash equivalents Cash and cash equivalents comprise cash on hand, deposits held at call with banks but do not include deposits with banks which are held to maturity over three months, and other short-term highly liquid investments with maturities of three months or less from the date of acquisition.

2.7

Trade accounts receivable/water loss treatment service income receivable Trade accounts receivable and water loss treatment service income receivable are carried at the original invoice amount and subsequently measured at the remaining amount less any allowance for doubtful receivables based on a review of all outstanding amounts at the year end. The amount of the allowance is the difference between the carrying amount of the receivable and the amount expected to be collectible. Bad debts are written off during the year in which they are identified and recognised in the income statement within administrative expense. The Group record revenue that has been recognised as revenue but not yet billed to the customers under “Unbilled receivables” and “Unbilled water loss treatment service income receivable” which have been included in trade accounts receivable and water loss treatment service income receivable in the balance sheets.

2.8

Inventories Inventories are stated at the lower of cost or net realisable value. Cost is determined by the first-in, first-out method. The cost of purchase comprises both the purchase price and costs directly attributable to the acquisition of the inventory, such as import duties and transportation charges, less all attributable discounts. Allowance is made, where necessary, for obsolete, slow moving and defective inventories.

2.9

Investments Investments in held-to-maturity debt securities, classified as current investments or longterm investment in accordance with their remaining periods to maturity, are stated at amortised cost less allowance for impairment (if any). The premium/discount on debt securities is amortised using the straight-line method with the amortised amount included in statements of income. Investment in non-marketable equity security held as other investment is determined at cost less allowance for impairment (if any). Loss on impairment (if any) of investments is included in the statements of income.

2.10 Property, plant and equipment Land is stated at cost less allowance for impairment (if any). Plant and equipment are stated at cost less accumulated depreciation and allowance for impairment (if any). Depreciation of plant and equipment is calculated on the straight-line basis to write off the cost of each asset, except for land which is considered to have an indefinite life over the estimated useful life as follows:

Pumping plants Buildings Land, leasehold and building improvements Machinery and equipment Office equipment Vehicles

33 years 15, 20, 25 years 5, 10, 15, 20 years 5, 10, 20, 25, 40 years 3, 5, 10 years 5 years

Where the carrying amount of an asset is greater than its estimated recoverable amount, it is written down immediately to its recoverable amount. Repairs and maintenance are charged to the income statement during the financial period in which they are incurred. The cost of major renovations is included in the carrying amount of the asset when it is probable that future economic benefits in excess of the originally assessed standard of performance of the existing asset will flow to the Group. Major renovations are depreciated over the remaining useful life of the related asset. Gains and losses on disposals are determined by comparing proceeds with the carrying amount and are included in operating profit. Interest costs on borrowings to finance the construction of property, plant and equipment are capitalised as part of cost of the asset, during the period of time required to complete and prepare the property for its intended use. The borrowing costs include interest on short-term and long-term borrowings, related taxes and amortisation of discounts or premiums relating to borrowings. All other borrowing costs are recorded as expense in statement of income.

2.11 Assets under concession contracts Assets under concession contracts are stated at cost less accumulated depreciation and allowance for impairment (if any). Depreciation of assets under concession contracts has been included in statements of income.which has been computed using the straight-line method over estimated useful life but not exceed the concession period of 15, 20 and 25 years, 2.12 Deferred concession rights acquisition costs Concession rights acquisition costs consist of expenses incurred directly in relation to obtaining the concession contracts from the Provincial Waterworks Authority. Deferred concession rights acquisition costs are stated at cost less accumulated amortisation and allowance for impairment (if any). Amortisation of deferred concession rights acquisition costs, which has been computed using the straight-line method over the concession periods of 27 and 30 years, has been included in statements of income.

2.13 Intangible assets Intangible assets presented as an asset in the consolidated balance sheets are rights to operate the subsidiariesâ&#x20AC;&#x2122; businesses under concession awarded to the subsidiaries by the government agency or entity over a limited a concession period. Rights are stated at cost less accumulated amortisation and allowance for impairment (if any) and are amortised using the straight-line method over a period of 27 years, being the concession period awarded to the subsidiaries to carry out their business operation. The carrying amounts of intangible assets are written down when there is an impairment.

2.14 Impairment of assets Assets that have an indefinite useful life, are not subject to amortisation and are tested annually for impairment. Assets that are subject to amortisation are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. An impairment loss is recognised for the amount by which the carrying amount of the assets exceeds its recoverable amount which is the higher of an assetâ&#x20AC;&#x2122;s fair value less costs to sell and value in use. For the purposes of assessing impairment, assets are grouped at the lowest level for which there are separately identifiable cash flows. Non-financial assets other than goodwill that suffered an impairment are reviewed for possible reversal of the impairment at each reporting date. 2.15 Provisions Provisions, excluding the provisions for employee benefits, are recognised when the Group has a present legal or constructive obligation as a result of past events, it is probable that an outflow of resources will be required to settle the obligation, and a reliable estimate of the amount can be made. Where the Group expects a provision to be reimbursed, for example under an insurance contract, the reimbursement is recognised as a separate asset but only when the reimbursement is virtually certain. 2.16 Leases - where a Group company is the lessee Leases of property, plant or equipment which substantially transfer all the risks and rewards of ownership are classified as finance leases. Finance leases are capitalised at the inception of the lease at the lower of the fair value of the leased property or the present value of the minimum lease payments. Each lease payment is allocated to the principal and to the finance charges so as to achieve a constant rate on the finance balance outstanding. The outstanding rental obligations, net of finance charges, are included in other long-term payables. The interest element of the finance cost is charged to the statement of income over the lease period so as to achieve a constant periodic rate of interest on the remaining balance of the liability for each period. The property, plant or

equipment acquired under finance leases is depreciated over the shorter period of the useful life of the asset or the lease term. Leases not transferring a significant portion of the risks and rewards of ownership to the lessee are classified as operating leases. Payments made under operating leases (net of any incentives received from the lessor) are charged to the statement of income on a straight-line basis over the period of the lease. When an operating lease is terminated before the lease period has expired, any payment required to be made to the lessor by way of penalty is recognised as an expense in the period in which termination takes place.

2.17 Employee benefits The Group operates a provident fund that is a defined contribution plan. The assets of which are held in a separate trust fund. The provident fund is funded by payments from employees and by the relevant Group companies. Contributions to the provident fund are charged to the statement of income in the year to which they relate. The Group provides for post-employment benefits, payable to employees under the Thai Labour Law. The amounts payable in the future depend on the salary and years of service of the respective employees. The Group recognise employee benefits as expenses when incurred.

Critical accounting estimates, judgments and assumptions

Estimates, judgments and assumptions are continually evaluated and are based on historical experience and other factors including expectations of future events that are believed to be reasonable under the circumstances. Significant accounting judgments and estimates are as follows:

3.1 Value in use Value in use is the present value of the future cash flows expected to be derived from assets, discounted by discount rates, determined by the management of the Group. The cash flow projections based on financial forecasts for the remaining useful lives of assets or concession periods and approved by the management of the Group are calculated based on estimated growth rates, which do not exceed their capacity and customersâ&#x20AC;&#x2122; usage demand. Key assumptions used for value-in-use calculations are growth rates, expense to revenue ratios and gross margin rate. Management determines such rates based on their past performance, their expectations for market development, and business plan. The discount rates used are pre-tax and reflect specific risks relating to the business after considered the remaining useful lives. The value derived from the afore-mentioned method may vary due to changes in revenue structure, cost structure, discount rate, industrial conditions and economic conditions.

3.2 Leases In determining whether a lease is to be classified as an operating lease or finance lease, the management is required to use judgment regarding whether significant risk and rewards of ownership of the leased asset has been transferred, taking into consideration terms and conditions of the arrangement.

3.3 Allowance for doubtful accounts In determining an allowance for doubtful accounts, the management needs to make judgment and estimates based upon, among other things, past collection history, aging profile of outstanding debts and the prevailing economic condition.

3.4 Property plant and equipment/Depreciation In determining depreciation of plant and equipment, the management is required to make estimates of the useful lives and salvage values of the plant and equipment and to review estimate useful lives and salvage values when there are any changes. In addition, the management is required to review property, plant and equipment for impairment on a periodical basis and record impairment losses in the period when it is determined that their recoverable amount is lower than the carrying cost. This requires judgments regarding forecast of future revenues and expenses relating to the assets subject to the review.

3.5 Intangible assets The initial recognition and measurement of intangible assets, and subsequent impairment testing, require management to make estimates of cash flows to be generated by the asset or the cash generating units and to choose a suitable discount rate in order to calculate the present value of those cash flows.

3.6

Litigation The Group has contingent liabilities as a result of litigation. The Groupâ&#x20AC;&#x2122;s management has used judgment to assess of the results of the litigation and believes that no significant loss will result. Therefore no contingent liabilities are recorded as at the balance sheet dates.

3.7

Fair value of financial instruments In determining the fair value of financial instruments that are not actively traded and for which quoted market prices are not readily available, the management exercise judgment, using a variety of valuation techniques and models. The input to these models is taken from observable markets, and includes consideration of liquidity, correlation and longerterm volatility of financial instruments. The critical fair value estimation of financial instruments is long-term loans from financial institutions. The Group estimates the fair value by calculating the present value of future principal and interest payment using the market interest rate for discounting.

Capital risk management

The Groupâ&#x20AC;&#x2122;s objectives when managing capital are to safeguard the Groupâ&#x20AC;&#x2122;s ability to continue as a going concern in order to provide returns for shareholders and benefits for other stakeholders and to maintain an optimal capital structure to reduce the cost of capital. In order to maintain or adjust the capital structure, the Group may adjust the amount of dividends paid to shareholders, return capital to shareholders, issue new shares or sell assets to reduce debt.

30.5 Project compensation A government agency is considering a deal for the Company to rent/manage the 2 pipeline connecting projects (â&#x20AC;&#x153;projectsâ&#x20AC;?) and adjust the compensation. A letter issued by this government agency stipulated that the Company was to initially pay compensation for the projects at a percentage of the raw water sales from the projects from the year operation commenced. In addition, if it is decided that a fair rate is more than the rate at which the Company already paid, the Company is to make additional payment, in full, as a lump sum; while if the fair rate is lower, the government agency agrees to pay back the surplus paid by offsetting it against the remuneration of the following years. On 8 January 2010, the government agency as mentioned in first paragraph issued a letter to the Company notifying it that a deal for the Company to rent/manage the projects and the adjusting of compensation must be processed in accordance with the Act on Private Participation in a State Undertaking B.E. 2535, whereby a committee has, under Section 13, authority to set the compensation rate and negotiate benefits with the Company, in order to reach a preliminary conclusion. The conclusion will then be proposed to the Cabinet for a resolution in accordance with Section 21 of that Act. Currently, approval is being considered by the Office of the National Economic and Social Development Board, and the Ministry of Finance, in order to propose to the Cabinet, in accordance with Section 16 of the Act. In order to be properly and appropriately in the process, a committee under Section 13 assigned the government agency, as mentioned in first paragraph, to consult the Council of State in their consideration of whether the deal for the Company to rent/manage should begin with the process of the Act on Private Participation in a State Undertaking B.E. 2535 under Section 13 or section 6 before. Then, the Council of State notified the government agency that there are no matters of law for their consideration. Therefore, this case is currently being considered by the Office of the National Economic and Social Development Board, and the Ministry of Finance, in order to propose to the Cabinet as mentioned in the previous paragraph.

30.6 Penalty for late work and deliver water below minimum requirement A subsidiary entered into a sale and purchase agreement for tap water for Chonburi Waterworks, Chonburi Province with the Provincial Waterworks Authority on 3 June 2009, which is scheduled to produce and supply water to the Provincial Waterworks Authority by 1 December 2009. Thereafter, the subsidiary entered into another sale and purchase agreement for tap water with a private company in order to construct a tap water production system to support the agreement with the Provincial Waterworks Authority as mentioned above. However, the private company could not complete the construction on time. As a result, the subsidiary has an obligation to pay compensation, which was calculated starting from December 2009 to March 2010 and a fine which was calculated starting from 1 December 2009 to actual completion date on 11 April 2010, totalling Baht 32.0 million to the Provincial Waterworks Authority. The subsidiary fully paid this liability on August 2010. However, the subsidiary will be able to charge for the compensation and fine together with interest charge 7.5% per annum from the private company by offsetting with the tap water cost that the subsidiary purchases every month from that private company. The subsidiary, therefore, recorded the balance after offsetting in part of other receivable included in other current assets of Baht 17.0 million in the consolidated financial statement as at 31 December 2010. In addition, since the subsidiary began to supply water to the Provincial Waterworks Authority on 12 April 2010, the subsidiary has not delivered water to the daily minimum requirements. The subsidiary, therefore, recorded the compensation and fine in the financial statements as at 31 December 2010 of Baht 16.05 million. However, The Provincial Waterworks Authority issued a letter to the subsidiary to claim the compensation and fine for being unable to deliver water achieving the daily minimum requirements from April to November 2010, totaling Baht 62.1 million due to different basis for calculation being applied. Then, in February 2011, the Provincial Waterworks Authority notified the subsidiary that the calculation methods of the compensation have been revised to the same calculation basis as that of the subsidiary. Therefore, the subsidiary did not record the different amount as additional liabilities in the financial statements. In addition, the subsidiary is able to charge this compensation and fine to the private company as mentioned in the first paragraph.

31 Litigation

118

31.1 On 28 March 2003, the Company was sued as a defendant in a litigation case in connection with the purchase of assets from the Legal Execution Department. The plaintiff petitioned the civil court to void the sales transaction or order the payment of compensatory damages amounting to Baht 302.2 million to the plaintiff. However, on 26 January 2006, the Court of First Instance issued an order dismissing the lawsuit and later the plaintiff lodged an appeal with the Court of Appeal on 22 March 2006. The Company

has already made its plea contesting the plaintiff’s appeal and as at 31 December 2010, the case is currently being heard by the Appeal Court. On 8 February 2011, the Appeal Court upheld the judgment of the Court of First Instance. 31.2 On 14 March 2006, Universal Utilities Company Limited, a subsidiary, was sued as a codefendant together with the Provincial Waterworks Authority (“PWA”) in a case brought in connection with illegal acts performed by administrative agencies or state officials. The plaintiff petitioned the administrative court to void the selection process by which a private operator was selected to produce tap water for distribution to the PWA in the area belonging to the Rayong Waterworks. On 16 March 2007, the Rayong Administrative Court ordered the selection process voided in accordance with the plaintiff’s petition, and also declared void the agreement appointing a private firm to produce water for sale to the Rayong Waterworks, which had resulted from an illegal selection process. However, the PWA and the subsidiary lodged appeals with the Rayong Administrative Court on 12 April 2007 and the Rayong Administrative Court has issued a court receipt for such appeal and then passed it to the Supreme Administrative Court. The case is currently at the stage of concluding the facts of the owner’s arbitrator at the appeals level of the Supreme Administrative Court under the court receipt No. Aor. 278/50. Since PWA and the subsidiary have to comply with conditions in the agreement and are further obliged to each other as stipulated in the agreement until the case is finalised, in accordance with Section 70 of the Royal Decree on Establishment of and Procedures for Administrative Court Act B.E. 2542, the subsidiary management therefore believes that the subsidiary will incur no losses as a result of the termination of the agreement because, if such a termination occurs the PWA will have to compensate the subsidiary for costs of construction and improvements made to the waterworks, and for other expenses incurred by the subsidiary. Therefore, no provision has yet been made in the accounts. 31.3 On 20 October 2008, the Company was sued by a company in a lawsuit with a black case number 5930/2551 regarding a breach of a construction agreement. The litigation filed with the Civil Court by the plaintiff requested that the Company pay damages totaling Baht 40.2 million. On 29 December 2008, the Company filed a lawsuit with a black case number 6848/2551 regarding a breach of a construction contract, suing the aforementioned company and a local commercial bank as the work guarantor of that company. The litigation filed with the Civil Court by the Company requested that the defendants pay damages totaling Baht 37.4 million. On 26 January 2009, the Civil Court set a date for the settlement of issues under the lawsuit with the black case number 5930/2551. However, the attorney of the Company has petitioned the Court to merge the settlement of issues of the lawsuit with the black case number 6848/2551 to be in one case since both cases are based on the same factual information. The Court considered the request and set a date for the settlement of issues of these two lawsuits on 23 March 2009.

119

On 23 March 2009, the Civil Court set a date for investigation of plaintiffâ&#x20AC;&#x2122;s witnesses during 17 - 19 February 2010 and a date for investigation of defendantâ&#x20AC;&#x2122;s witnesses during 23 - 24 February 2010. On 30 July 2010, The Civil Court delivered its judgement of the red case number 3169/ 2553 and 3170/2553 which can be summarised as follows: 1. The litigant is required to pay a fine of Baht 8.8 million, return the advance payment of Baht 2.1 million and pay for wage supervisors during late work period of Baht 0.2 million, totalling a payment of Baht 11.1 million. 2. The Company is required to pay the 30th and 31st installment of construction cost according to the agreement of Baht 13.0 million together with the additional costs of Baht 7.0 million and the return of retention costs of Baht 3.8 million, totalling Baht 23.8 million. Moreover, the Company is required to return all eight bank guarantees to the litigant. However, for the benefit of the Company a lawyer was appointed to lodge an appeal with the court on 29 October 2010 regarding the fine and the additional costs. The Company has recorded liabilities of the construction costs and the retention costs of Baht 16.8 million in this interim financial statement. Moreover, the Company has not recorded the additional costs of Baht 7.0 million which has not yet finalised.

31.4 On 3 June 2009, the subsidiary was sued by a former employee under labor law with a black case number 3630/2552, in relation to the termination of the employment by the subsidiary. The plaintiff lodged the lawsuit with the Central Labor Court, seeking compensation amounting to Baht 36.9 million. On 25 December 2009, the Central Labor Court issued an order dismissing the lawsuit. Subsequently, the plaintiff did not lodge an appeal with the Court within the deadline, so the case has been finalised.

33. Financial instruments

124

33.1 Financial risk factors The Group’s financial instruments principally comprise cash and cash equivalents, trade accounts receivable, trade accounts payable, short-term and long-term loans and retentions payable. The Group’s activities expose it to a variety of financial risks, including the credit risk and interest rates risk. The Group’s overall risk management programme focuses on the unpredictability of financial markets and seeks to minimise potential adverse effects on the financial performance of the Group. The financial risk management is discussed below. 33.1.1 Credit risk The Group are exposed to credit risk primarily with respect to, trade accounts receivable, and other receivable. The Group manage the risk by adopting appropriate credit control policies and procedures and therefore does not expect to incur material financial losses. Although the Group may expose to concentration risk due to their having a few large customers, those customers are in government sector. The management believes that such risk is therefore low. The maximum exposure to credit risk is limited to the carrying amounts of trade accounts receivables, and other receivable as stated in the balance sheets. 33.1.2 Interest rate risk The Group’s exposure to interest rate risk relate primarily to their deposits with financial institutions and short-term and long-term loans. However, since most of the Group’s financial assets and liabilities bear floating interest rates or fixed interest rates which are close to the current market rate, the interest rate risk is expected to be minimal. Significant financial assets and liabilities as at 31 December 2010 classified by type of interest rates are summarised in the table below, with those financial assets and liabilities that carry fixed interest rates further classified based on the maturity date, or the repricing date if this occurs before the maturity date.
