Esso Thailand Public : Financial Statement for Fourth Quarter and the year

ESSO (THAILAND) PUBLIC COMPANY LIMITED

CONSOLIDATED AND SEPARATE FINANCIAL STATEMENTS 31 DECEMBER 2019

Independent Auditor's Report

To the shareholders (and the Board of Directors) of Esso (Thailand) Public Company Limited

My opinion

In my opinion, the consolidated financial statements of Esso (Thailand) Public Company Limited (the Company) and its subsidiaries (the Group) and the separate financial statements of the Company present fairly, in all material respects, the consolidated and separate financial position of the Group and of the Company as at 31 December 2019, and its consolidated and separate financial performance and its consolidated and separate cash flows for the year then ended in accordance with Thai Financial Reporting Standards (TFRSs).

What I have audited

The consolidated financial statements and the separate financial statements comprise:

• the consolidated and separate statements of financial position as at 31 December 2019;
• the consolidated and separate statements of comprehensive income for the year then ended;
• the consolidated and separate statements of changes in equity for the year then ended;
• the consolidated and separate statements of cash flows for the year then ended; and
• the notes to the consolidated and separate financial statements, which include a summary of significant accounting policies.

Basis for opinion

I conducted my audit in accordance with Thai Standards on Auditing (TSAs). My responsibilities under those standards are further described in the Auditor's responsibilities for the audit of the consolidated and separate financial statements section of my report. I am independent of the Group and the Company in accordance with the Federation of Accounting Professions under the Royal Patronage of His Majesty the King's Code of Ethics for Professional Accountants together with the ethical requirements that are relevant to my audit of the consolidated and separate financial statements, and I have fulfilled my other ethical responsibilities in accordance with these requirements. I believe that the audit evidence I have obtained is sufficient and appropriate to provide a basis for my opinion.

Key audit matters

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

Key audit matter

Revenue Recognition

In 2019, the Group recognised revenues of Baht 168,529 million which derived from two main business segments, Downstream and Petrochemical segments, as disclosed in the Notes 4 to the financial statements. In addition, TFRS 15 Contracts with Customers has become effective on 1 January 2019 and impacted to the Group's revenue recognition.

The revenues are determined and recognised, based on the contractual price and volume of products delivered. The price is based on the market price and a number of other factors, depending on the distribution channels and contract terms with customers. The volumes sold are measured using applicable meters when the products are delivered to customers via pipeline, truck, or vessel.

I focused on the revenue recognition of the petroleum products and petrochemical products because the revenue amounts and number of revenue transactions are material. In addition, selling prices are based on market prices and a number of other factors as stated in the contracts with customers.

Cost of Inventory

As of 31 December 2019, the Group held inventories, mainly petroleum and petrochemical products, of Baht 8,073 million which represent 12 percent of the Group's total assets.

Cost of inventories primarily comprise purchase prices of crude oil and the manufacturing costs which are allocated to each type of products. Cost calculation requires the Group to perform the following procedures :

• Generating an automated report that computes the unit cost of each product. From this report, the production costs of inventories are pooled together and are allocated to each product using percentage of each product reference value to total production costs;
• Performing a comparison between product unit costs and market prices to ensure there is no significant unusual item; and
• Using final unit costs for calculation of

inventory balance using FIFO application.

I focused on this area because the sizes of inventory balances from petroleum and petrochemical products are material to the Group's financial statements. In addition, the calculation of inventory cost is complex. The accuracy and the completeness of information used for unit cost calculation are important which influences pricing decision and the Group's profit and loss.

How my audit addressed the key audit matter

My work performed over revenue recognition included:

• Obtaining an understanding and making inquiries tomanagement about revenue recognition principleand the Group's implementation of TFRS15, accounting guidelines, disclosures and systems to support revenue recognition to assess correctness and appropriateness of the adoption of this new accounting standard and accounting policies the Group applied.
• Obtaining an understanding and testing the design andoperating effectiveness of key controls in relation to the recognition of revenues, particularly focus on controls around the timely and accurate recording of sales transactions;
• Testing gross sales transactions and credit/debit noteson sampling basis by tracing to relevant supporting documents, including invoices to customers, delivery documents and subsequent cash receipts from those customers. Additionally, I inspected sales contracts and/or other related documents between the Group and customers to determine whether the revenue transactions were recognised correctly and appropriately.
• Selecting revenue samples prior to and after year endto test whether they are recorded in appropriate timing, based on terms and conditions set out in sales invoices and delivery documents or system generated reports; and
• Sending debtor confirmations for balances as at 31 October2019, completing appropriate roll-forwardprocedures and performing subsequent receipt testing on customer balances for which confirmations were not received.

From the procedures performed, I found that the revenue recognition of the petroleum products and petrochemical products was appropriately applied in accordance with theGroup's accounting policies.

My work performed over cost of inventories included:

• Obtaining an understanding and testing the design and operating effectiveness of key controls in relation to over the inventory management and procurement cycle to the purchase requisitions, purchase orders, goods receiving, payments and recording to reflect the accuracy of the cost of inventory;
• Testing purchase transactions in relation to timing, amounts and volumes on sampling basis by tracing to relevant supporting documents, including invoices from suppliers and receiving documents.
• Obtaining an understanding of basis of inventory cost to identify appropriateness of accounting policies the Group applied;
• Comparing unit cost of each product with its market price as at the reporting date to ensure there is no significant unusual item; and
• Engaging specialists in Information Systems and Technology to verify accuracy and reliability of the reports used in cost allocation.

From the procedures performed, I found that cost of inventories is calculated and allocated based on appropriate methodologies which are consistent with the Group's accounting policies.

Key audit matter	How my audit addressed the key audit matter

Valuation of deferred tax assets on net losses carried forward

As of 31 December 2019, the balance of deferred income tax assets relating to net losses carried forward of the Group was Baht 929 million which represents approximately 1 percent of the Group's total assets. The Group recognises deferred tax assets from tax losses carried forward to the extent it is probable that future taxable profits will allow it to be recovered.

Management of the Group has performed a financial performance projection of the Group, including expected future taxable profit to support recoverability of such deferred tax assets. The projection is based on historical data and expected future outcome. The significant assumptions include refining margin, production volumes, and crude prices.

I focus on this area because there are a number of assumptions used in the Group's financial performance projection. Those assumptions involve significant judgement made by management in assessing the Group's future taxable profit. In addition, the balance of deferred income tax assets from net losses carried forward is significant to the consolidated financial statements.

I evaluated evidence supporting the recoverability of the deferred tax assets from net losses carried forward which is management's projected future taxable income byperforming procedures below.

• Evaluating and challenging management's judgement andassumptions used in forming its four-yearfinancial performance projection, which includes the assumptions for future growth of refinery margin, production volumes, and crude prices. The reasonableness of these underlying assumptions were verified against external sources, industry benchmarks, and historical information.
• Developing an independent projection of the Group'sfuture taxable income using researched information and verified internal information, with no significant differences from the result that the Group's management prepared.

Based on procedures I have carried out, I consider that management's key assumptions underlying the projection offuture taxable income to be within a reasonable range.

Other information

The directors are responsible for the other information. The other information comprises the information included in the annual report, but does not include the consolidated and separate financial statements and my auditor's report thereon. The annual report is expected to be made available to me after the date of this auditor's report.

My opinion on the consolidated and separate financial statements does not cover the other information and I will not express any form of assurance conclusion thereon.

In connection with my audit of the consolidated and separate financial statements, my responsibility is to read the other information and, in doing so, consider whether the other information is materially inconsistent with the consolidated and separate financial statements or my knowledge obtained in the audit or otherwise appears to be materially misstated.

When I read the annual report, if I conclude that there is a material misstatement therein, I am required to communicate the matter to the audit committee.

Responsibilities of the directors for the consolidated and separate financial statements

The directors are responsible for the preparation and fair presentation of the consolidated and separate financial statements in accordance with TFRSs, and for such internal control as the directors determine is necessary to enable the preparation of consolidated and separate financial statements that are free from material misstatement, whether due to fraud or error.

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

The audit committee assists the directors in discharging their responsibilities for overseeing the Group and the Company's financial reporting process.

Auditor's responsibilities for the audit of the consolidated and separate financial statements

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

As part of an audit in accordance with TSAs, I exercise professional judgment and maintain professional scepticism throughout the audit. I also:

• Identify and assess the risks of material misstatement of the consolidated and separate financial statements, whether due to fraud or error, design and perform audit procedures responsive to those risks, and obtain audit evidence that is sufficient and appropriate to provide a basis for my opinion. The risk of not detecting a material misstatement resulting from fraud is higher than for one resulting from error, as fraud may involve collusion, forgery, intentional omissions, misrepresentations, or the override of internal control.
• Obtain an understanding of internal control relevant to the audit in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Group and the Company's internal control.
• Evaluate the appropriateness of accounting policies used and the reasonableness of accounting estimates and related disclosures made by the directors.
• Conclude on the appropriateness of the directors' use of the going concern basis of accounting and, based on the audit evidence obtained, whether a material uncertainty exists related to events or conditions that may cast significant doubt on the Group and the Company's ability to continue as a going concern. If I conclude that a material uncertainty exists, I am required to draw attention in my auditor's report to the related disclosures in the consolidated and separate financial statements or, if such disclosures are inadequate, to modify my opinion. My conclusions are based on the audit evidence obtained up to the date of my auditor's report. However, future events or conditions may cause the Group and the Company to cease to continue as a going concern.
• Evaluate the overall presentation, structure and content of the consolidated and separate financial statements, including the disclosures, and whether the consolidated and separate financial statements represent the underlying transactions and events in a manner that achieves fair presentation.
• Obtain sufficient appropriate audit evidence regarding the financial information of the entities or business activities within the Group to express an opinion on the consolidated financial statements. I am responsible for the direction, supervision and performance of the group audit. I remain solely responsible for my audit opinion.

I communicate with the audit committee regarding, among other matters, the planned scope and timing of the audit and significant audit findings, including any significant deficiencies in internal control that I identify during my audit.

I also provide the audit committee with a statement that I have complied with relevant ethical requirements regarding independence, and to communicate with them all relationships and other matters that may reasonably be thought to bear on my independence, and where applicable, related safeguards.

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

These consolidated and separate financial statements were authorised for issue by the Board of Directors on 24 February 2020.

2 Accounting policies

The principal accounting policies applied in the preparation of these consolidated and separate financial statements are set out below:

2.1 Basis of preparation

The consolidated and separate financial statements have been prepared in accordance with Thai Financial Reporting

Standards ("TFRS") and the financial reporting requirements issued under the Securities and Exchange Act.

The consolidated and separate financial statements have been prepared under the historical cost convention except as disclosed in the accounting policy for the revaluation of available-for-sale investments

The preparation of financial statements in conformity with TFRS requires management to use certain critical accounting estimates and to exercise its judgement in applying the Group's accounting policies. The areas involving a higher degree of judgement or complexity, or areas where assumptions and estimates are significant to the consolidated and separate financial statements are disclosed in Note 3.

As at 31 December 2019, the current liabilities of the Group exceeded the current assets by approximately Baht 4,698 million. The Group currently has adequate financing sources to enable the payment of liabilities when they become due as follows: (1) uncommitted borrowing facilities from related companies and financial institutions in the amount of Baht 74,533 million, and (2) the ability to offer Baht 11,500 million of bills of exchange in a revolving program as approved by the Securities and Exchange Commission. Accordingly, the consolidated and separate financial statements have been prepared on a going concern basis and do not include any adjustments relating to the recoverability and classification of recorded asset amounts, or to amounts or classification of liabilities that may be necessary if the going concern basis of preparing the consolidated and separate financial statements is not appropriate.

An English version of the consolidated and separate financial statements have been prepared from the statutory financial statements that are in the Thai language. In the event of a conflict or a difference in interpretation between the two languages, the Thai language statutory financial statements shall prevail.

2.2 New and amended financial reporting standards that are relevant and have significant impacts to the Group

2.2.1 The Group has applied the following standard and amendments for their annual reporting commencing 1 January 2019

1. Thai Financial Reporting Standard no.15 (TFRS 15), Revenue from contracts with customers
   The standard provides principle and approach of revenue recognition under five-step process. The underlying principle is that the Group will recognise revenue to depict the transfer of goods or services to customers at an amount that the entity expects to be entitled to in exchange for those goods or services. It replaces the principles of transferring the significant risks and rewards of ownership of the goods or services to the buyer in accordance with TAS 18, Revenue and related interpretations.
   The Group has adopted the new TFRS 15, Revenue from contracts with customers from 1 January 2019 (initial application date) by applying the modified retrospective approach and the comparative figures have not been restated. The Group did not apply practical expedient relates to completed contracts and contract modifications as allowed by TFRS 15. Additionally, there is no change in timing or amount of revenue recognized under TFRS 15 as compared to TAS 18.
   The accounting policies for revenue from contracts with customers under TFRS 15 are disclosed in Note 2.18. The impact from adoption mainly concerns the reclassifications of non-current portion deferred charges which previously reported under prepaid rental and deferred charges, to other non-current assets as contract assets under TFRS 15 of Baht 1,650 million. The effects of reclassification are disclosed in Note 9, 16 and 18.

2.2.2 New and amended financial reporting standards that are effective for accounting period beginning or after 1 January 2020

Certain new and amended financial reporting standards have been issued that are not mandatory for current period end 31 December 2019 reporting period and have not been early adopted by the Group.

1. Financial instruments

The new financial standards relate to financial instruments are:

TAS 32	Financial instruments: Presentation
TFRS 7	Financial Instruments: Disclosures
TFRS 9	Financial Instruments
TFRIC 16	Hedges of a Net Investment in a Foreign Operation
TFRIC 19	Extinguishing Financial Liabilities with Equity Instruments

These new standards address the classification, measurement, derecognition of financial assets and financial liabilities, impairment of financial assets, hedge accounting, and presentation and disclosure of financial instruments.

The Group's management is currently assessing the impact of initial adoption of these standards relate to financial instruments.

1. TFRS 16, Leases
   Where the Group is a lessee, TFRS 16, Leases will result in almost all leases being recognised on the balance sheet as the distinction between operating and finance leases is removed. A right-of-use asset and a lease liability will be recognised, with exception on short-term and low-value leases.
   On 1 January 2020, the Group will apply TFRS 16, Leases and adjust cumulative impact to opening retained earnings (modified retrospective approach). From the preliminary impact assessment, the management expect that the Group will be affected by significant lease liabilities from contracts on land which service stations are operated and was previously classified as operating leases under TAS 17.
   The Group's management is currently assessing the impact of initial adoption of this standard.

2.3 Group Accounting - Investments in subsidiaries and associates

1. Subsidiaries
   Subsidiaries are all entities (including structured entities) over which the group has control. The group controls an entity when the group is exposed to, or has rights to, variable returns from its involvement with the entity and has the ability to affect those returns though its power over the entity. Subsidiaries are fully consolidated from the date on which control is transferred to the group. They are deconsolidated from the date that control ceases.
   The Group applies the acquisition method to account for business combinations. The consideration transferred for the acquisition of a subsidiary is the fair value of the assets transferred, the liabilities incurred to the former owners of the acquiree and the equity interests issued by the Group. The consideration transferred includes the fair value of any asset or liability resulting from a contingent consideration arrangement. Acquisition-related costs are expensed as incurred. Identifiable assets acquired and liabilities and contingent liabilities assumed in a business combination are measured initially at their fair values at the acquisition date. On an acquisition-by-acquisition basis, the Group recognises any non-controlling interest in the acquiree either at fair value or at the non-controlling interest's proportionate share of the acquiree's net assets.
   The excess of the consideration transferred, the amount of any non-controlling interest in the acquiree and the acquisition-date fair value of any previous equity interest in the acquiree over the fair value of the identifiable net assets acquired is recorded as goodwill. If the total of consideration transferred, non- controlling interest recognised and previously held interest measured is less than the fair value of the net assets of the subsidiary acquired in the case of a bargain purchase, the difference is recognised directly in profit or loss.
   Intercompany transactions, balances and unrealised gains or losses on transactions between Group companies are eliminated. Unrealised losses are also eliminated. Accounting policies of subsidiaries have been changed where necessary to ensure consistency with the policies adopted by the Group.
   In the Company's separate financial statements, investments in subsidiaries are accounted for at cost less impairment. Cost also includes direct attributable costs of investments. Details of the subsidiaries are included in Note 12.
2. Transactions with non-controlling interests
   The Group treats transactions with non-controlling interests as transactions with equity owners of the Group. For purchases from non-controlling interests, the difference between any consideration paid and the relevant share acquired of the carrying value of net assets of the subsidiary is recorded in equity. Gains or losses on disposals to non-controlling interests are also recorded in equity.
3. Associates
   Associates are all entities over which the Group has significant influence but not control, generally accompanying a shareholding of between 20% and 50% of the voting rights. Investments in associates are accounted for using the equity method of accounting. Under the equity method, the investment is initially recognised at cost, and the carrying amount is increased or decreased to recognise the investor's share of the profit or loss of the investee after the date of acquisition. The investments in associates of the Group including identifiable goodwill at the time the investment was acquired.
   The Group's share of its associate's post-acquisition profits or losses is recognised in the consolidated statement of comprehensive income, and its shares of post-acquisition movements in reserves are recognised in equity. The cumulative post-acquisition movements are adjusted against the carrying amount of the investment. When the Group's share of losses in an associate equals or exceeds its interest in the associate, including any other unsecured receivables, the Group does not recognise further losses, unless it has incurred obligations or made payments on behalf of the associate.
   The Group determines at each reporting date whether there is any objective evidence that the investment in the associate is impaired. If this is the case, the group calculates the amount of impairment as the difference between the recoverable amount of the associate and its carrying value and recognises the amount related to share of profit/(loss) of associates in the income statement.
   Unrealised gains on transactions between the Group and its associates are eliminated to the extent of the Group's interest in the associates. Unrealised losses are also eliminated unless the transaction provides evidence of an impairment of the asset transferred. Accounting policies of associates have been changed where necessary to ensure consistency with the policies adopted by the Group.
   In the Company's separate financial statements, the investment in an associate is accounted for at cost less impairment. Cost also includes direct attributable costs of investments. Details of the associate are included in Note 12.

(All amounts in Baht thousand unless otherwise stated)

1. Cash and cash equivalents
   Cash and cash equivalents includes cash on hand, deposits held at call with banks, and other short-term highly liquid investments with original maturities of three months or less. Bank overdrafts are shown within borrowings in current liabilities on the statement of financial position.
2. Trade receivables
   Trade receivables are carried at original invoice amount and subsequently measured at the invoice amount less allowance for impairment. An allowance for impairment is established when there is objective evidence that the Group will not be able to collect all amounts due according to the original terms of the receivables. Significant financial difficulties of the debtor, probability that the debtor will enter bankruptcy or financial reorganisation and default or delinquency in payments are considered indicators that the trade receivable is impaired. The amount of the allowance is the difference between the carrying amount and the amount expected to be collected. The carrying amount of the asset is reduced through the use of an allowance account, and the amount of the loss is recognised in the statement of comprehensive income within 'selling expenses'. The receivables are written-off against the allowance account when it is uncollectible. Subsequent recoveries of accounts previously written-off are credited against 'selling expenses' in the statement of comprehensive income.
3. Inventories
   Inventories are stated at the lower of cost or net realisable value. Cost is determined under the following methods:

Crude oil and petroleum products Petrochemical products Materials and supplies

Other merchandise

First-in,first-out method First-in,first-out method Average unit cost method Average unit cost method

Purchase cost includes the purchase price and costs directly attributable to the acquisition of the inventory, such as import duties and transportation charges, less all attributable discounts, allowances or rebates. The cost of finished goods is primarily comprised of raw materials, transportation costs, direct labour, and direct manufacturing expenditures. Net realisable value is the estimated selling price in the ordinary course of business, less applicable variable selling expenses. Allowance is made, where necessary, for obsolete, slow-moving, and defective inventories.

2.7 Investments Available-for-sale investments

Available-for-sale investments are non-derivatives that are either designated in this category or not classified in any of the other categories. They are included in non-current assets unless management intends to dispose of the investment within 12 months of the statement of financial position date.

Investments are initially recognised at fair value of consideration paid plus transaction costs. Investments are derecognised when the rights to receive cash flows from the investments have expired or have been transferred and the Group has transferred substantially all risks and rewards of ownership. Available-for-sale investments are subsequently carried at fair value based on the quoted bid price on the Stock Exchange of Thailand at the statement of financial position date.

Unrealised gains or losses arising from changes in the fair value of investments classified as available-for-sale are recognised, net of tax, in the consolidated and separate statement of comprehensive income. When investments classified as available-for-sale are sold or impaired, the accumulated fair value adjustments recognised in equity are included in the consolidated and separate statement of comprehensive income as part of other income or costs. Dividends on available-for-sale investments are recognised in the consolidated and separate statement of comprehensive income as part of other income when the Group's and Company's right to receive payment is established.

For the year ended 31 December 2019

(All amounts in Baht thousand unless otherwise stated)

1. Current and deferred income tax
   The tax expense for the period comprises current and deferred tax. Tax is recognised in profit or loss, except to the extent that it relates to items recognised in other comprehensive income or directly in equity. In this case the tax is also recognised in other comprehensive income or directly in equity.
   The current income tax charge is calculated on the basis of the tax laws enacted or substantially enacted at the statement of financial position date. Management periodically evaluates positions taken in tax returns with respect to situations in which applicable tax regulations are subject to interpretation and establishes provisions where appropriate on the basis of amounts expected to be paid to the tax authorities.
   Deferred income tax is recognised, using the liability method, on temporary differences between the tax base of assets and liabilities and their carrying amounts in the financial statements.
   However, the deferred income tax is not accounted for if it arises from initial recognition of an asset or liability in a transaction other than a business combination that at the time of the transaction affects neither accounting nor taxable profit or loss. Deferred income tax is determined using tax rates (and laws) that have been enacted or substantially enacted by the end of the reporting period and are expected to apply when the related deferred income tax asset is realised or the deferred income tax liability is settled.
   Deferred income tax assets are recognised only to the extent that it is probable that future taxable profit will be available against which the temporary differences can be utilised. Deferred income tax is provided on temporary differences arising on investments in subsidiaries and associates, except where the timing of the reversal of the temporary difference is controlled by the Group and it is probable that the temporary difference will not reverse in the foreseeable future.
   Deferred income tax assets and liabilities are offset when there is a legally enforceable right to offset current tax assets against current tax liabilities and when the deferred income tax assets and liabilities relate to income taxes levied by the same taxation authority.
2. Intangible assets
3. 1. Royalties and licenses
      Acquired royalties and licenses are shown at historical cost. Royalties and licenses have a finite useful life and are carried at cost less accumulated amortisation. Amortisation is calculated using the straight line method to allocate the cost of royalties and licenses over their estimated useful lives (5 to 20 years).
   2. Computer software
      Acquired computer software licenses are capitalised on the basis of costs incurred to acquire and bring to use the specific software. Costs associated with developing or maintaining computer software programs are recognised as an expense as incurred.
      Costs that are directly associated with the development of identifiable and unique software products controlled by the Group, and which will probably generate economic benefits exceeding costs beyond one year, are recognised as intangible assets. Costs include the software development employee costs and an appropriate portion of relevant overhead.
      Computer software development costs recognised as assets are amortised over their estimated useful lives (5 to 20 years).

2.10 Property, plant and equipment

Land is stated at historical cost. All other property, plant and equipment is stated at historical cost less accumulated depreciation. Historical cost includes expenditures that are directly attributable to the acquisition of the items.

Subsequent costs are included in the asset's carrying amount or recognised as a separate asset, as appropriate, only when it is probable that future economic benefits associated with the item will flow to the Group and the cost of the item can be measured reliably. All other repairs and maintenance are charged to the consolidated and separate statement of comprehensive income during the financial period in which they are incurred.

Depreciation is calculated using the straight-line method to allocate the cost of each asset, except for land which is considered to have an indefinite life, to its residual value over its estimated useful life, as follows:

Buildings, plant and equipment

3 to 25 years

An asset's carrying amount is written down immediately to its recoverable amount if the asset's carrying amount is greater than its estimated recoverable amount (Note 2.11).

Gains and losses on disposals are determined by comparing the proceeds with the carrying amount and are recognised within 'selling expenses', 'administrative expenses' and 'other income' in the statement of comprehensive income.

The capitalisation rate used to determine the amount of borrowing costs to be capitalised is the weighted- average interest rate applicable to the outstanding borrowings during the year. Where funds are borrowed specifically for the construction of property, plant and equipment, the amount of borrowing costs for capitalisation is determined from the actual borrowing costs during the period less any income on the temporary investment of those borrowings.

1. Impairment of non-financial assets
   Assets that are subject to depreciation or 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 asset's carrying amount exceeds its recoverable amount. The recoverable amount is the higher of an asset's fair value less costs to sell and value in use. For the purpose of assessing impairment, assets are grouped at the lowest levels for which there are separately identifiable cash flows (cash-generating units). Non-financial assets that have suffered an impairment are reviewed for possible reversal of the impairment at each reporting date.
2. Leases - where the Group is the lessee
   The Group leases certain property, plant or equipment. Leases of property, plant and equipment, where the Group has substantially 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 assets and the present value of the minimum lease payments.
   Leases in which a significant portion of the risks and rewards of ownership are retained by the lessor are classified as operating leases. Payments made under operating leases, net of any incentives received from the lessor, are charged to the statement of comprehensive income on a straight-line basis over the period of the lease.
3. Borrowings
   Borrowings are recognised initially at contractual amounts, net of transaction costs incurred. Borrowings are subsequently stated at amortised cost with any difference between the proceeds, net of transaction costs, and the redemption value being recognised in the consolidated and separate statement of comprehensive income over the period of the borrowings using the effective interest method.
   Borrowings are classified as current liabilities unless the Group has an unconditional right to defer settlement of the liability for at least 12 months after the end of reporting date.

1. Employee benefits
2. 1. Provident Fund Plan
      The Group operates a Provident Fund that is a defined contribution plan, the assets of which are held in a separate trust fund, in accordance with the Provident Fund Act B.E. 2530. The Provident Fund is funded by payments from employees and the Group. Contributions to the Provident Fund are charged to the statement of comprehensive income in the year to which they relate. All employees hired on or after 1 September 1997 are required to be members of the Provident Fund.
      The Group provides for post-employment benefits, payable to Provident Fund members reaching normal retirement age, in accordance with Thai Labour Law. The benefit liability is recorded as the present value of estimated future cash outflows using interest rates which have terms to maturity approximating the terms of the related liabilities.
   2. Employee Separation Benefit and Long Service Allowance Plan
      The Group maintains a defined benefit plan for employees hired prior to 1 September 1997 and who do not elect to participate in the Provident Fund, with this plan being unfunded. The plan contains Employee Separation Benefit and Long Service Allowance Plans, which is in accordance with the retirement laws and regulations of Thailand. Entitlement to these benefits is based on a minimum service period, final month's salary, and the plan provisions.
      Actuarial valuations of the benefit plan requirements are performed every 3 years using the projected unit credit method. Based on the valuation, appropriate provisions are accrued and all payments are made against the accumulated provisions. The liability recognised in the statement of financial position is the present value of the defined benefit obligation at the end of the reporting period.
      The present value of the defined benefit obligation is determined by discounting the estimated future cash flows using interest rates of Investment grade corporate bonds that are mainly denominated in the currency in which the benefits will be paid, and that have terms to maturity approximating to the terms of the related obligations.
      Actuarial gains and losses arising from experience adjustments and changes in actuarial assumptions are charged or credited to equity in other comprehensive income in the period in which they arise.
      Past-service costs are recognised immediately in profit or loss.
   3. Employee Savings Plan
      Beginning 2009, the Group operates an Employee Savings Plan for all regular Thai employees. The entitlement to this plan is based on a minimum service period of three years and the plan's provisions on withdrawal rights after vesting. This plan will vest 50 percent after three years and 100 percent after six years.
3. Provisions
   Provisions are recognised when the Group has a present legal or constructive obligation as a result of past events such that it is probable that an outflow of resources will be required to settle the obligation, and the amount has been reliably estimated. Where the Group expects a provision to be reimbursed, for example under an insurance contract, the reimbursement is recognised as a separate asset at the time when reimbursement is virtually certain.
   Provisions are measured at the present value of the expenditures expected to be required to settle the obligation. The increase in the provision due to passage of time is recognised as interest expense.
4. Share capital
   Ordinary shares are classified as equity. Incremental costs directly attributable to the issuance of new shares are shown in equity as a deduction, net of tax, from the proceeds.

1. Foreign currency translation
   Items included in the financial statements of each of the group's entities are measured using the currency of the primary economic environment in which the entity operates ('the functional currency'). The financial statements are presented in Thai Baht, which is the Company's functional and the Group's presentation currency.
   Foreign currency transactions are translated into the functional currency using the exchange rates prevailing at the dates of the transactions or valuation where items are re-measured. Foreign exchange gains and losses resulting from the settlement of such transactions and from the translation at year-end exchange rates of monetary assets and liabilities denominated in foreign currencies are recognised in profit or loss.
   When a gain or loss on a non-monetary item is recognised in other comprehensive income, any exchange component of that gain or loss is recognised in other comprehensive income. Conversely, when a gain or loss on a non-monetary item is recognised in profit or loss, any exchange component of that gain or loss is recognised in profit or loss.
2. Revenue recognition
   Revenue include all revenues from ordinary business activities. All ancillary income in connection with the sales of goods and rendering of services in the course of the Group's ordinary activities is also presented as revenue.
   Revenue are recorded net of value added tax. They are recognised in accordance with the provision of goods or services, provided that collectability of the consideration is probable.
3. 1. Sales of goods
      Sales are recognised when control of the products has transferred, being when the risks and rewards of ownership have passed to the buyer, which is generally at the point of delivery, and there is no unfulfilled obligation that could affect the customer's acceptance of the products.
   2. Sales of services and other operating revenues
      The Group receives rental income and franchise fees from dealers who operate branded retail stations. Rental income and franchise fees are recognised over the contract's term. Service revenues are recognised in the period in which the services are provided.
   3. Interest income
      Interest income is recognised on a time-proportion basis using the effective interest method.
   4. Dividend income
      Dividend income is recognised when the right to receive payment is established.

When inventories are exchanged or swapped for inventories which are of a similar nature and value, the exchange is not considered a transaction which generates revenue.

Contract assets and contract liabilities

A contract asset is recognised where the Group has performed by transferring goods or services to a customer before the customer pays for consideration or before payment is due.

A contract liability is recognised when the customer paid consideration or a receivable from the customer that is due before the Group fulfilled a contractual performance obligation.

2.19 Government Grants

Grants from the government are recognised at their fair value where there is a reasonable assurance that the grant will be received and the Company will comply with all attached conditions.

Government grants relating to the compensation of costs are recognised in profit or loss over the period necessary to match them with the costs they are intended to compensate.

Government grant, which is subsidy from oil fuel fund, is separately presented from revenue from sales.

(All amounts in Baht thousand unless otherwise stated)

1. Dividend distribution
   Dividend distribution to the Company's shareholders is recognised as a liability in the Group's financial statements in the period in which the dividends are approved by the Company's shareholders or Board of Directors (as the case maybe).
2. Financial instruments
   Financial assets carried on the statement of financial position include cash and cash equivalents, trade receivables, amounts due from related parties, loans to related parties, and other assets. Financial liabilities carried on the statement of financial position include borrowings from financial institutions, trade and other payables, amounts due to related parties, loans from related parties, and other liabilities. The particular recognition methods adopted are disclosed in the individual policy statements associated with each item where applicable.
3. Segment reporting
   Segment results that are reported to the Group's Management Committee (the chief operating decision maker) include items directly attributable to a segment as well as those that can be allocated on a reasonable basis.

3 Critical accounting estimates and judgements

Estimates and judgements 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.

Critical accounting estimates and assumptions

The Group makes estimates and assumptions concerning the future. The resulting accounting estimates will, by definition, not necessarily equal the related actual results. The estimates and assumptions that have a significant risk of causing a material adjustment to the carrying amounts of assets and liabilities within the next financial year are discussed below.

Recognition of deferred tax assets associated with tax losses carried forward

A deferred tax asset is recognised to the extent it is probable that the tax losses carried forward will be utilised. Such an assessment is based upon management's review of the forecasted financial income.

Asset retirement obligations

It is recognised that the Group may incur asset retirement obligations for the dismantling and site restoration costs of its manufacturing facilities. The timing and amount of cash flows is difficult to estimate as the Group has no intention to decommission the sites in the near future. Accordingly and consistent with industry practice, no provision is recorded for asset retirement obligations as the amount cannot be measured with sufficient reliability due to the significant uncertainties involved.

4 Segment information

As at 31 December 2019, the Group is organised into two main business segments, namely:

• Downstream, which includes the refining and marketing of petroleum products; and
• Petrochemicals, which includes the manufacturing and marketing of chemical products.

Inter-segment transactions are priced under normal commercial terms and conditions that would also be available to unrelated third parties.

The principal actuarial assumptions used were as follows:

					Impact on defined benefit obligation
					0.5 % Increase	0.5 % Decrease
		Assumption		in assumption	in assumption
		2019		2018	2019	2018	2019	2018
Discount rate	2.75%		3.75%	Decrease by	Decrease by	Increase by	Increase by
					3.64 %	3.78 %	3.85 %	4.01 %
Salary growth rate	7.00%		7.00%	Increase by	Increase by	Decrease by	Decrease by
					3.68 %	3.87 %	3.52 %	3.69 %

The discount rate used is based on investment grade corporate bonds with tenure approximating the tenure of the employee benefit liability. The salary growth rate takes into account market factors such as projected market salary growth and incorporates assumptions relating to inflation rates.

The Group does not anticipate a change in expected rate of salary increase based on historical data.

The above sensitivity analysis is based on a change in an assumption while holding all other assumptions constant. In practice, this is unlikely to occur, and changes in some of the assumptions may be correlated. When calculating the sensitivity of the defined benefit obligation to significant actuarial assumptions, the same method (present value of the defined benefit obligation calculated with the projected unit credit method at the end of the reporting period) has been applied as when calculating the pension liability recognised within the statement of financial position.

The methods and types of assumptions used in preparing the sensitivity analysis did not change compared to the previous period.

Through its defined benefit, the Group is exposed to a number of risks, the most significant of which are changes in bond yields. A decrease in Investment grade corporate bond yields will increase plan liabilities.

Expected maturity analysis of undiscounted employee benefits:

30 Financial risk management

The Group's activities expose it to a variety of financial risks, which include market risk (including market prices for petroleum commodities risk, foreign exchange risk and interest rate risk), credit risk, liquidity risk, and capital risk.

1. Market risk
2. 1. Market prices for petroleum commodities risk
      The Group's financial results can be significantly affected from time to time by volatility and cyclical movement in the market prices for crude oil, petroleum, and petrochemical products. Given the large size and the long-term nature of its business, the Group expects that this risk will be moderated over time. The Group does not employ the use of derivative instruments to manage the risk.
   2. Foreign exchange risk
      The Group's activities are exposed to foreign exchange risk arising from various currency exposures, primarily with respect to the US Dollar. Purchases of goods and export sales are primarily transacted in US Dollars. Domestic sales are transacted predominantly in Baht, and are thus not subject to foreign exchange risk.
      As at 31 December 2019 and 2018, the Group had no short-term or long-term debt denominated in foreign currencies. In 2019, the Group did not enter into any forward foreign currency contracts. The Group's foreign exchange guidelines prohibit speculative foreign exchange transactions.
   3. Interest rate risk
      As the Group has no significant interest bearing assets, the Group's income and operating cash flows are substantially independent of changes in market interest rates.
      The interest rate risk arises from borrowings that are issued at variable interest rates exposing the Group to cash flow interest rate risk. The Group continually optimises the mix in its borrowing facilities to maximise financing flexibility while minimising financing cost.
3. Credit risk
   Credit risk is managed on a Group basis. Credit risk primarily arises from cash and cash equivalents, and credit exposures to commercial and retail customers, including outstanding receivables and committed transactions. Credit risk in respect to balances outstanding with related parties has been assessed to be low due to the overall strength of the ExxonMobil Group.
   In the case of cash and cash equivalents, only independently rated banks with a minimum rating of at least BBB-, or equivalent, are accepted.
   For trade customers, risk evaluations are performed internally which include reviews of financial position, business success indicators, past experience, and other factors. Individual risk limits are set based on the resulting internal ratings in accordance with limits set by management. Risk categories are established for individual customers based on internal credit guidelines ranging from very low to very high risk. The risk categories are intended to reflect the risk of payment default by a customer and are similar to the rating scales established by external rating agencies.

(All amounts in Baht thousand unless otherwise stated)

1. Liquidity risk
   The Group manages liquidity risk by maintaining a minimum operating level of cash and cash equivalent balances. In addition, the Group maintains committed credit facilities as well as a number of uncommitted credit facilities from banks and related parties. The Group reviews requirements for future cash flows through the completion of an annual finance plan. The finance plan is completed for the forthcoming year to ensure that estimates of future requirements are analysed such that appropriate facilities can be made available.
   The Group currently has adequate financing sources. As at 31 December 2019, the Group has uncommitted facilities of Baht 74,533 million (2018: Baht 83,251 million). The Group has also received an approval from the Securities and Exchange Commission to offer for sale Baht 12,000 million of bills of exchange in a revolving program, of which Baht 500 million has been utilised as of 31 December 2019.
   Liquidity risk may also arise if customers are not able to settle obligations to the Group within the normal credit term. To manage this risk, the Group periodically assesses financial viability of customers and may require certain customers to provide bank guarantees or other similar instruments.
2. Capital risk
   The Group's objective when managing capital is to safeguard the Group's ability to continue as a going concern in order to provide returns to shareholders and benefits to other stakeholders. In the future, the Group may adjust the amount of dividend paid to shareholders in order to maintain an appropriate capital structure. Annually, the Group completes a finance plan which seeks to establish positions for the current and future years' dividend projections.
