Knowledge makes for a better future. There is a big difference between “tomorrow� and “future�. At PTT, knowledge and creativity keep PTT, Thais, and the world on a relentless march to security. At the crux, however, is how not to cling to past successes, but instead how to create dynamic innovations and new knowledge. That knowledge comes from one’s appreciation of one’s own way of life and surroundings-and then turning it into a leading to sustainable contentment.

Another attestation is the Green Globe Award, an extended program from the “Reforestation Project in Honor of His Majesty the King on the occasion of the 50th Anniversary of the Accession to the Throne;� Dating back to 1999, which won this year’s “National Outstanding Project Award (conservation of natural resources and the environment)� from the National > ?

PTT Group’s competitiveness, PTT and other three subsidiaries set up PTT Energy Solutions Co., Ltd., to provide Group companies with engineering technical services in the company’s effort to become a Technical Center of Excellence.

For instances, our investment in the promising coal business by acquiring shares in Straits Resources Limited and our jointventure in a hydropower plant in Lao People’s Democratic Republic.

For the 19th consecutive year, we still maintained our Â…_ `† market share (a 1.3% rise from last year) and for lubricant products for the third consecutive year.

This year the International Trading Business Unit successfully sharpened its competitive edge by growing petrochemicals, thus paving the way for business capacity building. For instance, we signed a crude oil purchase agreement for Seria Light crude oil with Brunei Shell Petroleum Co. Sdn.

Also as important is the consideration for more investment opportunities in related downstream businesses to build on

As a commitment to business-driven technical expertise through environmentally friendly technology, we are sparing no resource to explore other alternative-energy products that can be further developed to establish viable sustainableenergy businesses in the future. A notable example is bio-jet fuels, which lower aviation emissions under the Emission Trading Scheme (ETS) enacted in European countries: To a satisfying result, we conducted an experiment with Thai Airways International Plc’s planes. Another is PTT Bi-Fuel =?‹ on indigenous natural gas. To support the technology, in collaboration with Mitsubishi Chemical Corporation, we set up PTT MCC Biochem Co., Ltd., to develop a project

The world economic growth this year ended up far below anticipated. Developing and emerging economies, led by China and India, were the main drivers of global economic growth as a result of their stringent monetary policies to curb rising prices of oil and commodities while the economic growth of developed economies was continuously weakening. The US economy remained sluggish following the continued high unemployment, a non-recoverable property market, and limited success of the US government’s economic stimulation > |[ … ‹ œ Standard & Poor’s (S&P) consequently lowered the credit rating on the US long-term debt securities from AAA to AA+, a historic credit rating cut for the US. EU member countries, on the other hand, failed to resolve the huge public debts. The debt crisis has escalated from Greece, Ireland, and Portugal to Italy and Spain, two major regional economies. Consequently, S&P and Moody’s Investors Service (Moody’s) slashed credit ratings which triggered a series of blows to the world monetary and capital markets. In addition, the Great Earthquake and Tsunami of Japan devastated the global industrial supply which caused 2009-2011 World Economic Growth Unit: % yoy

major shortages of parts and materials for manufacturing worldwide, thus compounding the world economic contraction. The International Monetary Fund (IMF), in its January 2012 report, announced a world economic growth record for 2011 at 3.8%, a big drop from the 2011 level of 5.2%. The average economic growth for developing and emerging economies was recorded at 6.2%, while the record for developed countries was only 1.6%.

Petroleum and Petrochemical Review

The world economic growth continued to drive the oil demand higher from 2010 by 0.7 million barrels per day to an average of 89.0 million barrels a day in 2011, according to the International Energy Agency (IEA) 's January report in 2012. Developing and emerging economies, particularly China, India, and the Middle East were the main sources of higher demand. The actual oil demand this year was not much higher. However, the political unrest in Middle Eastern and Northern African countries (MENA) since 2009 had strained supply in the world oil market. IEA decided to call for its member countries to release 60 million barrels from the Strategic Petroleum Reserves to offset the 1.6 millionbarrel a day shortfall from Libya, following the escalating political unrest in that country.

On the contrary, with the government’s approval to raise the LPG price quarterly for industrial use by 3 baht per kilogram in July and October to reduce LPG usage in industries, its consumption in this sector shrank by 7.8%. Meanwhile, Thailand continued to import LPG: this year’s total imports totaled more than 1.4 ‰ ‚ š ` _{ per kilogram, NGV consumption jumped 27.4% to 231 million cubic feet per day, as consumers deserted the considerably high gasoline prices. Energy consumption this year by economic sector is summarized as follows. 1. The transportation sector consumed 577,130 barrels a day, up by 6% from 2010. Aviation jet fuel consumption went up by 7.7% due to the economic expansion in Asia. Consumption of LPG and NGV rose by 35.3% and 27.4% „ Consumption of gasoline dropped by 1.6% as a result of rising world market oil prices and a sudden drop in demand over two months in many provinces, including Bangkok, „ – diesel price gap of 30 baht a liter since December 2010, this

On the other hand, ethanol consumption this year dropped by 2%, following the change in government policy to reduce excise tax contribution to the Oil Fund from gasoline, resulting in a narrower price gap between gasoline (91 and 95) and gasohol (91 and 95) respectively. Also affected by the policy on a single commercial biodiesel grade with a 4% to 5% mixture of palm oil (B100), depending on the internal palm oil market, production and consumption of biodiesel jumped 9%. 2. The industrial sector consumed 433,959 barrels a day, an increase from 2010 of 4%, affected by the Great Earthquake and Tsunami of Japan early in the year and by the Great Flood in Thailand later in the year. The consumption pattern in this sector this year was similar to that of previous years, with the exception of a jump of 27.3% in the consumption of natural gas and a drop in LPG usage due to the government measure to gradually increase the price of LPG from July 19 this year by 3 baht per kilogram each quarter for four consecutive quarters, resulting in the substitution of LPG by natural gas. 3. Household and commercial energy consumption rose by 5% from 2010 to 207,509 barrels a day. The government continued to ease economic hardship with free buses and free passenger trains, free electricity use for household consuming power less than a given limit per month, and the capping of LPG prices for household cooking at 18.13 baht per kilogram. As a result, LPG consumption surged by 9.1% this year. This year, the overall procurement of petroleum registered 1,791.98 KBD, a drop of 1.06% from last year.

1.1 Gas Unit : The PTT Gas Business Unit conducts natural gas supply procurement, transmission, distribution, and processing, and invests in NGV service stations and sales, as well as gas-related value-added businesses through Group companies. Supply includes indigenous gas and imports from neighboring countries via natural gas transmission pipelines system, ” ~ ‚ €

The distribution network includes major power producers through PTT’s gas transmission pipelines, industrial users through PTT-invested gas distribution pipelines, and NGV distribution through NGV service stations. NGV is an alternative fuel for vehicles, in addition to gasoline and diesel. PTT also invests in gas separation plants to create additional business value by separating a variety of valuable chemical components from natural gas to provide petrochemical industry feedstock, which in turn represents essential elements of all other subsequent industries driving Thailand’s economic growth.

Ever since the privatization into PTT Plc. and distribution of Company’s shares on the Stock Exchange of Thailand (SET) in late 2001, it has valued corporate governance as its guiding principles. PTT regulations state: “The Company must have and implement a policy on its business ethics, including the ethics of its Board of Directors, the senior management, the administration and employees in compliance with good corporate governance practices as its code of conduct for the proper conduct of the organization with high standard.� So, PTT subsequently issued its rules on good corporate governance in 2001 and published them as the handbook for each director, the management, and the

employees to sign, acknowledge and comply with. The 2001 handbook was the Z – in 2005 and 2009 in line with the changing business and social environment, so as to align with the SET principles of good corporate governance, 2006 version, for listed companies as well as the Organisation for Economic Co-Operation – ~ =?–€ " ? namely the rights of shareholders, equitable treatment of shareholders, roles of stakeholders, information disclosure and transparency and the responsibilities of the Board. New topics-respect for human rights, for consumers’ rights and for intellectual property-were added to suit business circumstances and laws. Such handbooks were regarded as a code of ethics under the Thai Constitution of B.E. 2550 (2007). The revised 2009 Handbook and the Code of Conduct were disseminated on PTT’s intranet and website. Below are the essences of PTT’s corporate governance practices:

If the meeting decided to change the order of the agenda, it would need at least two-thirds of the vote of the shareholders in attendance. Alternatively, the shareholders with at least one-third of

To segregate policy-making duties from those of dayto-day management and to enable directors to oversee, look after, and assess performance effectively, PTT has required that the Chairman and the President & CEO are always two distinct persons. This is because the Chairman needs to oversee the management’s performance, guide and assist, but not to take part in or interfere with day-to-day management, which is the duty of the President & CEO under the frame of authority delegated by the Board. In addition, the Chairman must exercise leadership „ of the management, partly by chairing Board meetings Q

encouraging participants to exercise their voting rights and strictly comply with good corporate governance principles.

5.8 Independence of the Chairman

PTT highly values the independence of the Board; however, since it is a listed company on SET while remaining a state enterprise under the Ministry of Energy, with the Ministry of Finance serving as the major shareholder, most of the elected Chairmen to date have come from the management of either ministry. Yet, they have consistently displayed strong independence. 5.9 Corporate Secretary

To comply with the good corporate governance principles of listed companies under the category of directors’ responsibility and the terms of the Securities and Exchange Act, PTT has appointed Mrs. Sumon Rungkasiri as Corporate Secretary to provide the Board with legal advice and remind them of assorted regulations that they need to know and comply with; hold meetings; supervise assorted Board "&&Y critical documents including Directors’ registration, Board meeting notices and minutes, annual reports; shareholders’ meeting notices and minutes and keep reports on connected transactions reported by Directors or the management. 5.10 Committees

The Board values corporate governance by initially appointing three committees: the Audit Committee, the Nominating Committee, and the Remuneration Committee. For a period, the Audit Committee also looked after corporate governance and risk management for the Board. In 2004, the Board set up the Corporate Governance Committee, charged with promotion and screening of corporate governance and promotion of excellence in such areas. PTT today therefore has four committees investigating critical matters under the corporate governance principles to create stakeholders’ concerns and interests, business ethics, transparency and accountability. Each of these committees ” � ” SET, with clearly written roles and responsibilities in a charter.

By the resolution of Board meeting No. 10/2011 of October 28, 2011, the Board approved the self-assessment forms used last year for use again this year. The form is aligned with PTT’s good corporate governance principles. The form was to be used to conduct self-assessment of the Board’s performance, and serves as a vital tool for improving Board performance and providing reference data for the corporate governance rating. Three types of self-assessments were applied, whereby the percentages corresponded to the following levels of performance achieved in each of the areas detailed below. These are the assessment criteria for the entire board, individual self-assessment forms, and cross self-assessments:

Report of Board of Directors’

Responsibilities for the Financial Reporting

To Shareholders, The Board of Directors is responsible for the financial statements of PTT Public Company Limited and its subsidiaries. The aforementioned financial statements are prepared in accordance with generally accepted accounting principles. The financial statements are prepared under appropriated accounting policies and applied consistently by using careful judgment and the best estimation. Important information is adequately and transparently disclosed in the notes to financial statements for the Company’s shareholders and investors. The Board of Directors provides good corporate governance and maintains the risk management system and internal controls to ensure that accounting records are accurate, reliable, timely and adequate to protect the Company’s assets as well as to prevent fraud and significant irregular operations. The Board of Directors has appointed an Audit Committee comprising independent directors to be responsible for reviewing the reliability and correctness of financial reports as well as evaluating the effectiveness of internal control system and internal audit. The audit committee’s comments on these issues are presented in the audit committee report included in this annual report. The Board of Directors considers that the internal control system and the internal audit of the Company provide credibility and reliability to the financial statements of PTT Public Company Limited and its subsidiaries for the year ended December 31, 2011. The Board of Directors also believes that the financial position, financial results and cash flows, audited by the independent auditors (The Office of Auditor General of Thailand), are fairly presented in all material respects with generally accepted principles. The auditors’ opinion is presented in the auditors’ report as part of this annual report.

AUDITOR’S

REPORT

TO: THE SHAREHOLDERS OF PTT PUBLIC COMPANY LIMITED The Office of the Auditor General of Thailand has audited the accompanying consolidated statements of financial position of PTT Public Company Limited and its subsidiaries and the separate statements of financial position of PTT Public Company Limited as at December 31, 2011 and 2010, the related consolidated and the separate statements of income, comprehensive income, changes in equity, and cash flows for the years then ended. These financial statements are the responsibility of the Company’s management as to their correctness and completeness of the presentation. The responsibility of the Office of the Auditor General of Thailand is to express an opinion on these financial statements based on the audits. The Office of the Auditor General of Thailand does not audited the financial statements of some subsidiaries, some jointly controlled entities arising from joint investing between PTT Public Company Limited and other companies, and some jointly controlled entities arising from joint investing between subsidiaries and other companies, included in the consolidated financial statements. As at December 31, 2011, assets and liabilities of the above subsidiaries and jointly controlled entities included in the consolidated financial statements constitute 28.86% and 13.78% and as at December 31, 2010 constitute 34.64% and 33.80%, respectively. The financial statements of those subsidiaries and jointly controlled entities were audited by other auditors whose reports have been furnished to the Auditor General of Thailand and the report of the Auditor General of Thailand, insofar as it relates to the amounts included for those subsidiaries and jointly controlled entities, is based solely on the reports of the other auditors. The Office of the Auditor General of Thailand conducted the audits in accordance with generally accepted auditing standards. Those standards require the Office of the Auditor General of Thailand to 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. The audit also includes assessing the accounting principles used and significant estimates made by the management, as well as evaluating the overall financial statement presentation. The Office of the Auditor General of Thailand believes that the audits together with other auditors’ reports as aforementioned provide a reasonable basis for the opinion. In the opinion of the Office of the Auditor General of Thailand based on the audits and the other auditors’ reports, the consolidated and the separate financial statements referred to above present fairly, in all material respects, the consolidated and the separate financial position of PTT Public Company Limited and its subsidiaries and of PTT Public Company Limited as at December 31, 2011 and 2010, and the results of operations, and the cash flows for the years then ended in accordance with generally accepted accounting principles.

Presentation of Financial Statements

From January 1, 2011, the Group has applied Thai Accounting Standard No.1 (revised 2009) – Presentation of Financial Statements. Under the revised accounting standard, a set of financial statements comprises: •  Statement of financial position; •  Statement of comprehensive income; •  Statement of changes in equity; •  Statement of cash flows; •  Notes to the financial statements As a result, the Group presents all owner changes in equity in the statement of changes in equity and all non-owner changes in equity in the statement of comprehensive income. Previously, all such changes were included in the statement of changes in equity. Comparative information has been re-presented so that it is also in conformity with the revised accounting standard. Such change in accounting policy only impacts presentation aspects. 3.2.3

Property, Plant and Equipment

Since January 1, 2011, the Group has applied Thai Accounting Standard No.16 (revised 2009) – Property, Plant and Equipment in determining and accounting for the cost and depreciable amount of property, plant and equipment. The principal changes introduced by the revised Thai Accounting Standard No.16 and affecting the Group are that (i) costs of asset dismantlement, removal and restoration have to be included as asset costs and subject to annual depreciation; (ii) the depreciation charge has to be determined separately for each significant part of an asset; and (iii) in determining the depreciable amount, the residual value of an item of property, plant and equipment has to be measured based on the estimated amount that the Group would currently obtain from the asset’s disposal, if the asset were already of the age and in the condition expected at the end of its useful life. Furthermore, the residual value and useful life of an asset have to be reviewed at least at each financial year-end. The changes have been applied prospectively in accordance with the transitional provisions of the revised standard, except that consideration of the costs of asset dismantlement, removal and restoration, have been applied retrospectively.

3.2.4

PTT Public Company Limited   Financial Report

Investment Properties

Since January 1, 2011, the Group has applied Thai Accounting Standard No.40 (revised 2009) – Investment Property. Under the revised accounting standard, investment property, defined as property owned to earn rentals; capital appreciation; or both, is disclosed in the financial statements separately from other property, plant and equipment and measured using the cost model. The Group has selected the cost model for accounting for its investment properties under the revised accounting standard. The change in accounting policy has been applied retrospectively and for comparative purposes, investment properties presented in the financial statements for the year ended December 31, 2010 have been reclassified from ‘property, plant and equipment’ to present separately under ‘investment properties’. Moreover, the cost and accumulated depreciation as at January 1, 2010 and December 31, 2010 of the Group’s investment properties previously included in property, plant and equipment, have been reclassified and presented separately under ‘investment properties’. Apart from this reclassification, the change in policy has no impact on the 2010 financial statements. Details of investment properties are disclosed in Note 15. property, plant and equipment, have been reclassified and presented separately under ‘investment properties’. Apart from this reclassification, the change in policy has no impact on the 2010 financial statements. Details of investment properties are disclosed in Note 15.

Employee Benefits

Since January 1, 2011, the Group has applied Thai Accounting Standard No.19 – Employee Benefits. Under the new accounting policy, the Group’s obligation in respect of post-employment benefits, provision for employee pension, is recognized in the financial statements based on calculations performed annually by a qualified actuary using the projected unit credit method. Previously, this obligation was recognized as and when payments were made. The Group has opted to recognize actuarial science estimates in the statement of income in that period. The change in this accounting policy has been applied retrospectively and the Group’s 2010 financial statements have been restated for comparative purposes to the Group’s 2011 financial statements. Details of employee benefit obligations are disclosed in Note 26. 3.2.6

Share-based Payments

Since January 1, 2011, the Group has applied Thai Financial Reporting Standard No.2 – Share-based Payment. Thai Financial Reporting Standard No.2, share-based payment is a transaction in which the entity receives or acquires goods or services either as consideration for • its equity instruments (equity settled share-based payment) recognized in equity. • cash or other assets for amounts based on the price of the entity’s shares (cash settled share-based payment) recognized in liability The entity shall make no subsequent measurement to equity settled share-based payment after a granted date. However, the entity shall measure the fair value of goods or services received at each reporting date and at the date of settlement, with any changes in fair value recognized in profit or loss for the period. The Group has not applied the above accounting policy for share-based payment awards granted before January 1, 2011 in accordance with transitional provisions of Thai Financial Reporting Standard No.2. The adoption of this standard has had no material impact on the financial statements of the Group. Details of share-based payment awards granted before January 1, 2011 are disclosed in Note 32.

3.2.7

PTT Public Company Limited   Financial Report

Business Combinations

Since January 1, 2011, the Group has adopted Thai Financial Reporting Standard No.3 (revised 2009) – Business Combinations and Thai Accounting Standard No.27 (revised 2009) – Consolidated and Separate Financial Statements. Under the revised standard, for acquisitions on or after January 1, 2011, the Group measures goodwill at the acquisition date as: • The fair value of any consideration transferred plus • The recognized amount of any non-controlling interest in the acquiree, plus • The fair value of the existing equity interest in the acquiree, if the business combination is achieved in stages, less • The net recognized amount (generally fair value) of the identifiable assets acquired and liabilities assumed. When the excess is negative, a bargain purchase gain is recognized immediately in profit or loss. The consideration transferred excludes amounts related to the settlement of pre-existing relationships. Such amounts are generally recognized in profit or loss. Costs related to the acquisition, other than those associated with the registration and issue of debt or equity securities, that the Group incurs in connection with a business combination are expensed as incurred. Any contingent consideration payable is recognized at fair value at the acquisition date. If the contingent consideration is classified as equity, it is not remeasured and settlement is accounted for within equity. Otherwise, subsequent changes in the fair value of the contingent consideration are recognized in profit or loss. When share-based payment awards (replacement awards) are required to be exchanged for awards held by the acquiree’s employees (acquiree’s awards) and relate to past services, then all or a portion of the amount of the acquiree’s replacement awards are included in measuring the consideration transferred in the business combination. This determination is based on the market-based value of the replacement awards compared with the market-based value of the acquiree’s awards and the extent to which replacement awards relate to past and/or future service.

Change in Functional Currency of a Domestic Subsidiary

Since January 1, 2011, a subsidiary of the Company (PTT Exploration and Production Public Co., Ltd. (PTTEP)) has changed its functional currency from Thai Baht to USD so that the financial statements of PTTEP more accurately reflect the effects of trading transactions and other situations impacting financial position, operating results and cash flows of the Company. As the change above was considered a change in accounting policy, PTTEP restated its financial statements. The Group prepared consolidated financial statements based on PTTEP’s financial statements translated into Thai Baht.

Significant Accounting Policies

3.3.1

Cash and Cash Equivalents

Cash and cash equivalents comprise cash on hand, deposits held at call with banks and other short-term highly liquid investments which have original maturities within three months. Bank overdrafts and short-term loans from financial institutions are included in current liabilities in the statement of financial position. 3.3.2

Trade Accounts and Notes Receivable

Trade accounts receivable and notes receivable are carried at net realizable value. Doubtful accounts receivable are estimated at percentages based on the aging of outstanding receivables at the statement of financial position date and expected noncollectible amounts are estimated based on the amount of outstanding receivables at the statement of financial position date, the receivables’ repayment history and their current financial status. Bad debt is recorded as selling and administrative expenses in the statements of income. 3.3.3

Inventories

Inventories are stated at the lower of the cost of acquisition or net realizable value. Cost is determined using the weighted average cost method. The cost of inventory comprises total purchasing costs, payments related to purchasing, discounts, and quantity discounts as well as contributions to or compensation from the Oil Stabilization Fund. Net realizable value is the estimated selling price in the ordinary course of business, less the costs of completion and related selling expenses. When net realizable value of inventories is lower than cost of acquisition, it is presented under cost of goods sold in profit and loss. An allowance for impairment will be recognized for slow-moving, obsolete or defective inventories. 3.3.4

Materials and Supplies

Materials and supplies are stated at cost determined by using the weighted average cost method, less allowance for obsolete, defective or unserviceable items.

Investments in subsidiaries

Subsidiaries are those companies controlled by the parent company. Control exists when the parent company has the power, directly or indirectly, to govern the financial and operating policies of the subsidiaries so as to obtain benefits from their activities. The financial statements of subsidiaries are included in the consolidated financial statements from the date that control commences until the date that control ceases. The purchase method of accounting is used to account for the acquisition of subsidiaries. The cost of an acquisition is measured as the fair value of any consideration transferred, the recognized amount of any non-controlling interest in the acquiree, and the fair value of the existing equity interest as of the purchasing date (if the business combination is achieved in stages) • For each business combination, the Group measures the recognized amount of any non-controlling interest in the acquiree at either the fair value or the non-controlling interest’s proportionate share of the net of identifiable assets of the acquiree. • In the case of a business combination achieved in stages, the Group measures the acquisition-date fair value of the acquirer’s previously-held equity interest in the acquiree and recognized in the statement of income • Costs related to the acquisition, other than those associated with the registration and issue of debt and equity securities, are recognized as expenses in the statement of income. The Group measures the identifiable assets and liabilities acquired at fair value as of the acquisition date. Any changes in the equity interest in subsidiaries of the Group while control is retained are recorded in equity. Investments in subsidiaries have been presented in the separate financial statements under the cost method. A list of subsidiaries of the Group is set out in Note 12.1 and 12.2.

Investments in Associates

Associates are those companies in which the Group has significant influence, but not control, over the financial and operating policies. The Group uses the purchase method to record the acquisition of associates. Costs which are higher than the acquisitiondate fair value of identifiable assets and liabilities of the acquirer’s equity interest in associates are recorded as goodwill and included in the investment in associates. The consolidated financial statements include the Group’s share of the total recognized gains and losses from associates on an equity accounting basis, from the date that significant influence commences until the date that significant influence ceases. Unrealized gains or losses on transactions between the Group and its associates are eliminated to the extent of the Group’s interest in the associates unless the transactions provide evidence of impairment of the transferred assets. The Group records share of gains or losses from associates in proportion to the Group’s equity interest in those gains and losses. Any dividends received from associates are deducted from the book value of the investments. When the Group’s share of losses in associates equals or exceeds its interest in the associates, the Group does not recognize further losses, unless the Group has incurred collateral or constructive obligations or made payments on behalf of the associates. Investments in associates have been presented in the separate financial statements under the cost method and in the consolidated financial statements under the equity method. A list of associates of the Group is set out in Note 12.1 and 12.2.

Investments in Jointly Controlled Entities

Established by contractual agreement, jointly controlled entities are those entities over which the Group has joint control. Jointly controlled entities are accounted for by proportionate consolidation in the consolidated financial statements. Under this method, the Group includes its share of the jointly controlled entities’ revenues, expenses, assets, liabilities and cash flows on a line-by-line basis with similar items in the Group’s financial statements, from the date that joint control commences until the date that joint control ceases. The Group recognizes the portion of gains or losses on sales of assets by the Group to the jointly controlled entities that is attributable to other ventures. The Group does not recognize its share of gains or losses from the jointly controlled entities that results from the purchase of assets by the Group from the jointly controlled entities until it sells the assets to an independent party. However, when loss on the transaction evidences a reduction in the net realizable value of current assets or an impairment loss, the loss is recognized immediately. The Group’s interests in jointly controlled entities are presented in the separate financial statements under the cost method. A list of jointly controlled entities of the Group is set out in Note 12.1 and 12.2. 3.3.8

Other Investments

Investments other than investments in subsidiaries, associates, and jointly controlled entities are classified as available-forsale investments, and general investments. Investments in equity securities and mutual funds which are marketable securities are classified as available-for-sale investments and carried at fair value in the statements of financial position. Any value changes are recognized as unrealized gain (loss) and presented separately in other components of equity. Changes in value during period are presented in the comprehensive income statement. Investments in non-marketable securities, which are classified as general investments, are carried at cost in the statement of financial position less accumulated impairment losses to recognize the unrealized losses on investments if the value of the investments decreases substantially. Impairment testing is performed when there is a factor indicating that an investment might be impaired. If the carrying value of the investment is higher than its recoverable amount, impairment losses are recognized in the statements of income immediately. Upon the disposal of investments, the difference between the net disposal proceeds and the carrying amount is charged or credited to the statements of income. When disposing of part of the Group’s particular investment in debt or equity securities, the carrying amount of the part disposed is determined by reference to the weighted average carrying amount of the total holding of the investment.

3.3.11 Borrowing Costs

Borrowing costs comprise interest and other costs associated with the borrowings. Borrowing costs incurred on qualifying assets included in property, plant and equipment are capitalized as a cost of the qualifying property until substantially all the activities necessary to prepare the property for its intended use are completed. The capitalization rate used to determine the amount of borrowing costs to be capitalized is the weighted-average interest rate applicable to the outstanding borrowings during the year. When funds are borrowed specifically for the construction or the production of property, plant and equipment, the amount of borrowing costs for capitalization is determined from the actual borrowing costs during the year less any income on the temporary investment of those borrowings. All other borrowing costs are expensed in the period they incurred. 3.3.12 Property, Plant and Equipment

Property, plant and equipment are initially recognized at cost less accumulated depreciation and allowance for impairment. The costs comprise any costs directly attributable to bringing the asset to the location and condition necessary for it to be capable of operating in the manner intended by the management. These include decommission costs, delivery and restoration costs, and any obligation associated with either its acquisition or a consequence of having used the items. Repair and maintenance costs are recognized as expenses in the statements of income 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 exceeding 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. When replacement costs are recognized in the carried amount of the property, plant and equipment, the replaced items are to be written off. The Group depreciates each significant component of property, plant and equipment separately. The Group estimates the carrying amount of the property, plant and equipment based on current assessment of the future economic benefits. The Group reviews the recoverable amounts, the useful lives and depreciation methods of assets at least once a year.

032

PTT Public Company Limited   Financial Report

Depreciation is accounted for as expenses in the statements of income and is calculated using the straight-line method over the estimated useful lives of the assets, which are as follows: Buildings and building improvements

5 – 30 years

Machinery and equipment

5 – 40 years

Other assets

5 – 10 years

Land and construction in progress are not depreciated. Gains or losses on disposal of property, plant and equipment are determined by comparing the proceeds from sales with the carrying amounts on the disposal dates, and are included in operating income or loss. Oil and Gas Exploration and Production Properties The petroleum exploration and production business accounts for its oil and gas exploration and production properties in accordance with the successful efforts method for which the accounting policies are as follows: Cost of Properties The cost of properties comprises the total acquisition costs of concession rights or a portion thereof proportionate to the Company’s interest in the properties including decommissioning costs. Exploratory drilling costs are capitalized and are classified as assets of the projects if the exploratory wells have found proved reserves to be commercially produced. If the exploratory wells have not found proved reserves or found insufficient reserves for commercial operation, such drilling costs are expensed in the statements of income. Exploratory costs, comprising geological and geophysical costs as well as area reservation fees during the exploration stage, are charged as expenses in the statement of income when incurred. Development costs, whether relating to successful or unsuccessful development wells, are capitalized and classified as assets.

PTT Public Company Limited   Financial Report

033

Depreciation The capitalized acquisition costs of concession rights are depleted and amortized using the unit of production method based on estimated proved reserves. Depreciation, depletion and amortization of exploratory wells, development costs, equipment and the operating costs of support equipment as well as decommissioning costs, except unsuccessful projects, are calculated using the unit of production method based on estimated proved reserves or proved developed reserves. Changes in reserve estimates are recognized prospectively. Proved reserves and proved developed reserves are calculated by the Group’s own engineers and based on information from the jointly controlled entities. Carried Cost under Petroleum Sharing Contracts The petroleum exploration and production business records the carried cost under petroleum sharing contracts using the following accounting policies. Under Petroleum Sharing Contracts in which the government has a participating interest, some contracts require the contractor parties excluding the government to fund the costs of all exploration operations until determination of the first development area (carried cost). The carried costs are funded by the contractor parties at the proportion agreed among the parties. When the project commences production, the carried costs will be fully recouped without interest among the contractor parties under the agreed procedures, in the form of petroleum product sharing. The Group records the carried costs according to the type of petroleum operations, under the successful efforts method. Most of them are recorded as oil and gas properties in the statements of financial position while exploration expenses are recorded in the statements of income as detailed in Note 16.

3.3.13 Investment Properties

Investment properties are initially recognized at cost, including expenses directly associated with the asset acquisition, less accumulated depreciation and amortization. The Group has selected the cost model for accounting for its investment properties. This model is in accordance with that described in the accounting policy for property, plant and equipment. Depreciation is accounted for as expenses in the statements of income and is calculated using the straight-line method over the estimated useful lives of the assets, which range from 5-30 years. Land and construction in progress are not depreciated. 3.3.14 Intangible assets

Intangible assets are initially recognized at cost less accumulated amortization and impairment. Amortization is accounted for as expenses in the statements of income. The Group records the initial costs of intangible assets from business combination at the acquisition-date fair value of the assets. Intangible assets from other sources are initially recognized at their costs. Intangible assets include computer software licenses, asset rights such as gas transmission pipelines, resource exploration and valuation assets, and other intangible assets, such as other operating rights, patents, and customer contracts. Exploration and evaluation assets are intangible assets that are recognized at cost in a petroleum exploration and production business. If exploratory projects have found sufficient reserves to be commercially produced, assets under those projects will be transferred to assets under proved reserve project. Subsequently, their values are evaluated based on the method stated in Note 3.3.12 property, plant and equipment. If exploratory projects have not found proved reserves or found insufficient reserves for commercial operation, assets under those projects will be fully expensed in the statements of income. Other intangible assets are amortized and recorded as expenses in the statements of income using the straight-line method over the contract periods which range from 5-30 years, except customer contracts which are amortized based on estimated sales volume. The Group reviews the carrying amount and useful lives of intangible assets at least once a year.

3.3.15 Mining Properties

The coal business applies the following accounting policy for coal exploration and production properties including coal mining property rights and deferred mining exploration and development expenditures. Coal Mining Property Rights Coal mining property rights comprise the total acquisition costs of concession rights in coal mining including both coal mining exploration and development expenditures. Deferred Mining Exploration and Development Expenditures Exploration expenditures relating to areas of interest are recorded at cost as deferred exploration expenditures, which comprise net direct costs, such as licenses, geological and geophysical exploration expenditures, excluding general overheads and administrative expenditures not directly attributable to a particular area of interest, where: a) Such costs are expected to be recovered when the areas are successfully developed and mining operations commence, or from the sales of the areas of interest b) Exploration activities in the areas of interest have not reached the stage which permits a reasonable assessment of the existence of commercial recoverable reserves, and active operations in the areas of interest are continuing. The recoverable amount of exploration expenditures is thus dependent upon a successful development and receivable economic benefits. When the economic benefits are expected to be minimal or non-existent, deferred exploration expenditures are written off as expenses in the statements of income immediately. Development expenditures and costs of area development prior to commencement of operations are capitalized as deferred costs so long as they meet the above criteria and it is highly probable that they can create future economic benefits. Amortization Amortization of coal mining property rights is calculated using the units of production method over the production amount. The amortization of deferred mining exploration and development expenditures commences when commercial coal production activities commence, using the units of production method. The volume of proportional production and the useful lives of coal mining concessions are estimated and reviewed by the Group.

3.3.16 Goodwill

The Group records the initial value of goodwill at cost, representing the excess of the acquisition costs over the fair value of the net assets acquired. Where the fair value of the net assets exceeds the cost of acquisition at the acquisition date, the difference is recognized as a gain in the statements of income immediately. The Group recognizes goodwill at cost less accumulated impairment losses. The Group will carry out a test for impairment of goodwill at least once a year or when there are factors indicating that an investment might be impaired. To test for impairment, the Group allocates goodwill from business combinations to each cash-generating unit (or group of cash-generating units) that is expected to benefit from the synergies of the combination. The Group evaluates the recoverable amount of each cash-generating unit (or group of cash-generating units) and if it is lower than the carrying amount of the unit, the Group recognizes impairment losses. Allowance for impairment of goodwill will not be reversed. 3.3.17 Finance Leases – Where the Group is the lessee

Leases of property, plant and equipment, where the Group assumes substantially all the risks and rewards of ownership are classified as finance leases. The leased assets are capitalized at the lower of the estimated net present value of the underlying minimum lease payments or fair value. Each minimum lease payment is allocated between liabilities and finance charges in order to achieve a constant interest rate on the remaining balance of the liabilities. The finance leases’ liabilities less finance charges are presented as long-term loans. Interest expenses are charged to the statements of income over the lease period. Depreciation is charged over the shorter of the assets estimated useful life or the lease period. 3.3.18 Operating Leases – Where the Group is the lessee

Leases of property, plant and equipment where the lessor assumes a significant portion of the risks and rewards of ownership are classified as operating leases. Payments made under operating leases are charged to the statements of income using the straight-line method over the period of the lease. The costs incurred upon termination of the operating lease agreements prior their maturity, such as compensation paid to the lessor for such termination, are recognized as expenses in the period in which the termination takes place.

3.3.19 Advance Payments for Gas Purchased under Take-or-Pay Agreements

The Company has entered into gas purchase agreements with natural gas producers, under which the Company is required to take delivery of natural gas at annual minimum quantities. During each contract year, if the Company cannot accept natural gas according to the minimum quantities under the agreements, it is required to pay for the volume of natural gas which it cannot actually take (Take-or-Pay). After the end of each contract year, the Company and the natural gas producers have to agree on and accept the volume of gas that should be taken into the calculation of Take-or-Pay for that contract year, which is subject to the basis and conditions in the agreements. Under the agreements, the Company can take certain volumes of prepaid gas (Make-up) in subsequent years after taking delivery of natural gas at the minimum quantities for that given contract year. The Company recognizes its obligations under the agreements as advance payments for gas purchased. 3.3.20 Impairment of Assets

The Group performs the following tests for impairment of assets: • Assessment of goodwill is performed annually. • Impairment of property, land and equipment or other intangible assets will be made whenever there is an indication that an asset may be impaired. The Group recognizes impairment loss when the recoverable amount of an asset is lower than its carrying amount, which is the higher of the asset’s fair value less cost to sell and its value in use. The Group determines value in use by estimating the present value of future cash flows generated by the asset, discounted using a pre-tax discount rate which reflects current market assessments of the time value of money and the risk specific to the asset. In determining fair value less costs to sell, an appropriate valuation model is used. The calculation reflects the amount that the Group could obtain from the disposal of the asset in an arm’s length transaction between knowledgeable, willing parties, after deducting the costs of disposal. The Group recognizes an impairment loss in profit and loss.

3.3.21 Provision for Decommissioning Costs

The Group records a provision for decommissioning costs whenever it is highly probable that an obligation will arise as a result of a past event and the amount of the obligation can be reliably estimated. The Group recognizes a provision for decommissioning costs based on an estimate of the eventual costs that relate to the removal of the production facilities. These costs are included as part of the cost of the oil and gas properties and are amortized based on proved reserves using the unit of production method. The estimates of decommissioning costs are determined based on reviews and estimates by the Group’s engineers and management’s judgment. 3.3.22 Employee Benefit Obligations

Employee benefit obligations of the Group were measured and recognized as follows: 1. Short-term employee benefits are recognized in profit and loss as expenses when incurred. 2. Post-employment benefits – defined contribution plans The Company and its employees have jointly established a provident fund. The fund is monthly contributed by employees and by the Company. The fund’s assets are held in a separate trust fund and the Company’s contributions are recognized as expenses when incurred. 3. Post-employment benefits – defined benefit plans The obligation under the defined benefit plan is determined based on actuarial techniques, using the projected unit credit method, in order to determine present value of the obligation, current service cost and past service cost. These are recognized as a liability in statements of financial position and expenses in profit and loss. Actuarial gains and losses arising from post-employment benefits are recognized immediately as expense in profit and loss. 4. Other long-term employment benefits The obligation under the defined benefit plan is determined based on actuarial techniques, using the projected unit credit method, in order to determine present value of the obligation, current service cost and past service cost. These are recognized as a liability in statements of financial position and expenses in profit and loss. Actuarial gains and losses arising from post-employment benefits are recognized immediately as expense in profit and loss. 5. Termination benefits are recognized as a liability or an expense when, and only when, the Company is demonstrably committed to either: • terminate the employment of an employee or a group of employees before the normal retirement date; or • provide termination benefits as a result of an offer made in order to encourage voluntary redundancy.

3.3.23 Income tax

Current tax The Group is taxed on its non-promoted businesses pursuant to the Revenue Code of Thailand, the Petroleum Income Tax Act, B.E. 2514 (1971) and Amendment, B.E. 2532 (1989) and other applicable laws and regulations of other countries in which the Group has invested. Current tax is the expected tax payable on the taxable profit for the year, using tax rates enacted at the statements of financial position date in the taxable period, and any adjustment to tax payable in respect of previous years. Deferred tax Deferred tax is recognized in the statements of financial position using the liability method for temporary differences between the carrying amounts of tax bases of assets and liabilities and the carrying amounts in the financial statements. The principal temporary differences arise from the allowance for doubtful accounts, accumulated depreciation of plant and equipment and amortization of decommissioning costs, including compensation receivable from the Oil Stabilization Fund and differences between the fair value of acquired assets and their tax bases. Deferred tax is measured using the tax rates enacted at the statements of financial position date. Deferred tax assets are recognized to the extent that it is highly probable that the future taxable profits of the Group will be available against which the temporary differences can be utilized. Deferred tax assets are reduced to the extent that it is no longer probable that the related tax benefits will be realized. The Group records deferred tax directly to shareholders’ equity if the tax relates to items that are recorded directly to shareholders’ equity. Deferred tax assets and liabilities are offset when there is the legal right to settle on a net basis and the deferred tax balances relate to the same taxation authority.

3.3.24 Revenue Recognition

The Group recognizes revenue from sales upon the delivery of products or when the significant risks and rewards of ownership are transferred to the customers. Revenue from services is recognized over the period in which the services are rendered. These revenues are net of trade discounts. Other revenue is recognized on the following basis: Interest income - time proportion basis using the effective yields of interest bearing assets Royalty income - accrual basis in accordance with the substance of the relevant agreements Dividend income - when the right to receive the dividend is established. Revenue from sources other than those mentioned above is recognized using the accrual basis. 3.3.25 Earnings per share

Basic earnings per share is calculated by dividing the net income attributable to ordinary shareholders by the weighted average number of ordinary shares held by third parties in issue during the year. In calculating diluted earnings per share, the Group assumes that all potential dilutive ordinary shares issued to its managements and employees will be converted. As a result, net income of the Group recognized in the financial statements of the Company is adjusted to reflect the dilution of its shareholding that would be caused by such conversion. The calculation of the weighted average number of ordinary shares is based on market price (average price of the Company’s ordinary shares during the period) and the exercise price of the warrants in order to determine the number of ordinary shares held by third parties in the diluted earnings per share calculation.

3.3.26 Share-based payments

The Group measures equity-settled share-based payments at fair value of warrants at the grant date and expenses them over the vesting period of warrants, while presenting equity from share-based payments in shareholders’ equity. Measurement of the fair value of share-based payments requires the use of judgment and the selection of suitable assumptions regarding items such as the vesting period of the warrants, fluctuation in share price and dividend rate, etc. The Group did not apply the above accounting policy for share-based payment awards prior to January 1, 2011 in accordance with the transitional provisions of Thai Financial Reporting Standard No.2. Details of share-based payment awards granted before January 1, 2011 are disclosed in Note 32. 3.3.27 Financial Instruments

Financial assets in the statements of financial position include cash and cash equivalents, current investments, trade accounts receivable, other accounts receivable, short-term loans and long-term loans. Financial liabilities in the statements of financial position include bank overdrafts and short-term loans from financial institutions, trade accounts payable, other accounts payable, short-term loans and long-term loans. The particular recognition methods adopted are disclosed in the individual policy statements associated with each item. The Group utilizes financial instruments to reduce its risk exposure associated with fluctuations in foreign currency exchange rates, interest rates as well as oil and gas market prices. These instruments primarily comprise: Forward Foreign Exchange Contracts Forward foreign exchange contracts protect the Group from fluctuations in exchange rates by establishing the rates at which foreign currency assets will be realized or foreign currency liabilities will be settled. Forward foreign exchange contracts are recognized in the financial statements on inception. The premium or discount on the establishment of each agreement is amortized over the contract period.

PTT Public Company Limited   Financial Report

Cross-currency and Interest Rate Swap Contracts Cross-currency and interest rate swap contracts protect the Group from fluctuations in exchange rates and interest rates. Foreign currency financial assets and liabilities as at the statements of financial position date are protected by cross-currency contracts and are translated to Thai Baht using the rates determined in the contracts. Gains or losses on early termination of such contracts or on early-repayment of the borrowings before maturity are taken to the statements of income. Futures Oil Contracts The Company has entered into futures contracts to hedge risks arising from fluctuations in oil prices in accordance with its oil purchase and sale agreements by determining future oil prices. Gains or losses arising from these contracts are recorded in the statements of income at the maturity of the futures contracts. The risk management policy is described in Note 40: Disclosure of Financial Instruments. 3.3.28 Use of Estimates and Significant Assumptions

The preparation of financial statements in conformity with Thai Accounting Standards requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, income and expenses. Estimates and underlying assumptions used in the preparation of financial statements are reviewed 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 significant assumptions and the sources of contingent estimates that might impact on the carrying amounts of assets and liabilities presented in the financial statements are as follows:

PTT Public Company Limited   Financial Report

043

Provisions The Group recognizes a provision in the statements of financial position if, as a result of a past event, the Group has a present obligation that can be estimated reliably and it is probable that an outflow of economic benefits will be required to settle the obligation. The Group records provisions for decommissioning costs when it is highly probable that a commitment will arise as a result of past circumstances and the amount can be estimated reliably. The Group recognizes the provisions for decommissioning costs based on estimated amount of decommissioning of completed construction that is ready for its intended use. These costs are included as part of oil and gas exploration and production properties and are amortized using the units of production method based on estimated proved reserves. The provision for decommissioning costs is determined based on reviews and estimates by the Group’s engineers together with the management’s judgment. Provisions for decommissioning costs depend on various current circumstances such as laws and regulations, technological changes and market prices so the actual result is likely to be different from estimations and assumptions. Income Tax The Group is responsible for the payment of tax in various countries. When deferred tax liabilities are estimated, the Group uses significant judgment due to the numerous transactions and calculations arising from its operations. The Group recognizes deferred tax liabilities based on estimated incremental tax payments. The difference between the actual tax paid and the estimate will affect income tax and deferred tax in the period in which payment of the difference occurs. A deferred tax asset will be recognized when it is highly probable that the Group will have sufficient net income against which to utilize the temporary difference. Assumptions related to future taxable income are uncertain and may change affecting the recognition of deferred tax assets.

Estimation of Petroleum Reserves Petroleum reserves are of fundamental importance when assessing investments in various exploration projects and petroleum production businesses, including impairment testing. Changes in proved reserves will affect the present value based on net cash inflows and depreciation expenses which are calculated using the unit of production method. The proved reserves are the volume of commercial petroleum production as of a certain date with a high probability of achievement under current economic conditions and production methods, as well as government’s rules and regulations. The proved reserves will be checked and assessed annually by the Group’s geologists and reservoir engineers. Exploration Costs The petroleum exploration and production businesses capitalize drilling costs as assets. When they are over 12 months old, they are amortized as expenses in the statements of income except where there is (1) a discovery of proved reserves, or (2) a discovery of commercially adequate reserves whilst having future exploration and assessment plans. The decision to amortize drilling petroleum costs recorded as assets over 12 months should be made using the assumptions under current circumstances. In case those should such assumptions change in subsequent accounting periods, the petroleum drilling costs that are capitalized as assets will be written off as expenses in that accounting period. Impairment of Assets The Group considers recording an allowance for impairment of assets when an event or a circumstance indicates that the carrying amount of an asset is higher than its net realizable value, which is the higher of the anticipated discounted cash flows from the continuing use of the asset or the amount obtainable from the sale of the asset less any costs of disposal. As a result, the carrying amount of an asset is written down immediately to its net realizable value. The decrease is recorded in the statements of income. Thus, the loss on impairment of assets excluding goodwill recognized in the prior period will be reversed if the estimation for indicated net realizable value changes.

The Group’s estimate of the expected amount of future petroleum production (exploration and production business) is a key factor in impairment tests. The Group believes these to be the most reasonable indicators for estimating future cash flows because future petroleum production comprises proved reserves, including expected proved reserves. The estimation of discounted future cash flows depends on various factors such as the expected amount of future production, future selling prices, demand and supply in the market, risks and gross margins. The discounted rates used in the calculation of present value of future cash flows depend on the cost of capital of the asset unit. 3.3.29 Capital Risk Management

The capital management objective of the Group is to create returns for shareholders and other stakeholders whilst maintaining a reasonable capital structure to decrease the cost of capital. 3.3.30 Segment Information

The Group has presented its financial information by business segments, not by geographical segments because geographical segments other than Thailand account for less than 10% of consolidated revenues, operating results and total assets.
