In order to implement the Transactions, the Company is carrying out a series of internal reorganization with respect to the Target Assets as follows:

The Company proposes to convert its Pipeline Branch and Southwest Pipeline Branch, respectively, into two wholly-owned subsidiaries, and the Target Assets would include 100% of the equity interests in such two wholly-owned subsidiaries.

(e) Profit forecast under the Asset Appraisal Report

According to the Asset Appraisal Report, the total valuation on the Target Assets was performed based on the asset-based approach, of which, valuation of the DCF Assets under the Target Assets was performed based on the income approach. The valuation of the DCF Assets performed based on the income approach is regarded as a profit forecast under Rule 14.61 of the Hong Kong Listing Rules.

(i) Valuation assumptions

For the valuation performed based on the income approach, the Appraiser has adopted the following valuation assumptions:

General Assumption

1. Transaction Assumption

The transaction assumption assumes that the Target Assets are already in the process of transaction, and the Appraiser simulates the market for appraisal according to the transaction conditions of the Target Assets. The transaction assumption is one of the most basic preconditional assumptions for the performance of asset appraisal.

2. Public Market Assumption

10

The public market assumption assumes that, as for the subject assets traded in the market, or the subject assets to be traded in the market, both parties of asset trading have equal footings and have the opportunity and time to obtain sufficient market information, so as to make rational judgment on the functions, use and transaction price of the subject assets. The public market assumption is based on the fact that the subject assets can be publicly traded in the market.

3. Sustainable Operation Assumption

The sustainable operation assumption refers to such an assumption that, the Target Assets will continue to be used as per its current purpose and the manner, size, frequency and environment of use, or continue to be used on the basis of certain change therein, and the Appraiser determines the method, parameters and basis for appraisal accordingly.

Special Assumptions

There is no significant change in the current macroeconomic, financial and industrial policies of China.

There is no significant change in other social and economic environment where the Target Assets are located and other policies (such as tax policies and tax rates) implemented thereby.

The future operation and management team of the Target Assets will be diligent in their duties, and continue to maintain the existing operation strategies and continue to operate the Target Assets.

The Target Assets are based on the actual inventory on the Base Date, and the current market price of the Target Assets is based on the domestic effective price on the Base Date.

The basic data/information and financial data/information provided by the Group are true, accurate and complete.

The appraisal scope is only subject to and based on the appraisal declaration form provided by the Group, without taking into account the contingent assets and contingent liabilities that may exist outside the list provided by the Group.

In view of the frequent changes or significant changes in the monetary funds or bank deposits of the Group in the course of operation, as for the financial expenses under the Asset Appraisal Report, the Appraiser does not take into account the interest income generated by the deposits, nor consider the uncertain gains and losses such as exchange gains and losses.

It is assumed that the cash inflow and cash outflow of the companies holding the Target Assets after the Base Date are the average of such inflow and outflow.

(ii) Confirmation

KPMG, the Company's reporting accountants, has been engaged to issue a report dated 23 July 2020 on the calculations of the discounted future cash flows used in the Asset Appraisal Report, as required by paragraph 14.62(2) of the Hong Kong Listing Rules. The discounted future cash flows do not involve the adoption of accounting policies.

The financial advisers of the Company, Goldman Sachs (Asia) L.L.C., UBS AG Hong Kong Branch and China Securities (International) Corporate Finance Company Limited, have discussed with the Directors, the management of the Company and the Appraiser on the bases and assumptions upon which the profit forecast regarding the DCF Assets in the Asset

11

Appraisal Report has been prepared, and reviewed the profit forecast included in the Asset Appraisal Report upon which the valuation of the DCF Assets has been made. The financial advisers have also considered the report from KPMG. On the basis of the foregoing and subject to conditions set out in the Financial Adviser Letter (as defined below), the financial advisers confirmed that the profit forecast regarding the DCF Assets in the Asset Appraisal Report prepared using the income approach has been made after due and careful enquiries by the Directors and issued a letter dated 23 July 2020 in accordance with Rule 14.62(3) of the Hong Kong Listing Rules (the "Financial Adviser Letter").

The report from KPMG and the Financial Adviser Letter have been submitted to the Stock Exchange, and are included in Appendix I and Appendix II, respectively, to this announcement pursuant to Rules 14.60A and 14.62 of the Hong Kong Listing Rules.

Each of the experts mentioned above has given and none of the experts has withdrawn its written consent to the issue of this announcement with the inclusion of its letters, reports and/or opinions and the references to its names included herein in the form and context in which it is included.

As at the Latest Practicable Date, UBS AG and its affiliates held 428,001,753 shares of the Company (accounting for 0.23% of the total share capital of the Company), and 49,457,934 shares of Kunlun Energy, a subsidiary of the Company (accounting for 0.57% of the total share capital of Kunlun Energy). Save as disclosed above, none of the other experts nor their respective subsidiaries mentioned above held any shareholding, directly or indirectly, in any

12

member of the Group or any right (whether legally enforceable or not) to subscribe for or to nominate persons to subscribe for securities in any member of the Group.

As at the Latest Practicable Date, as far as the Directors are aware, none of the experts nor their respective subsidiaries mentioned above had, or had had, any direct or indirect interest in any material assets which have been since 31 December 2019 (being the date to which the latest published audited consolidated accounts of the Company were made up) acquired, or disposed of by, or leased to any member of the Group, or are proposed to be acquired, or disposed of by, or leased to any member of the Group.

3. FINANCIAL EFFECT OF THE TRANSACTIONS

The expected gains arising from the Transactions will be based on the appreciation value of the Target Assets of RMB45.82 billion. The final net gains will be subject to various factors including the value of the Target Assets on the Closing Date, the relevant taxes and fees incurred under the Transactions and the value of the Initial Oil and Gas at the time of delivery.

Upon completion of the Transactions, eight branches of the Company, including Pipeline Branch, and eight subsidiaries of the Company, including PetroChina Pipeline Co., Ltd., will no longer be consolidated into the financial statements of the Group. The Company will also no longer apply the equity method for accounting, or record the returns on the equity investment from four associated companies or joint ventures, including Guangdong Natural Gas Pipeline Network Co., Ltd. The Company, as the shareholder of PipeChina, will be entitled to receive the returns on the equity investment it has in PipeChina as a shareholder. The equity investment in PipeChina is expected to bring relatively stable long-term returns. However, due to changes in the national pricing policy on oil and gas pipeline transmission, downstream market demands and other factors, the profitability of PipeChina in the future is subject to uncertainty. The asset-liability ratio of the Group is expected to decrease upon completion of the Transactions.

4. USE OF PROCEEDS FROM THE TRANSACTIONS

The proceeds in cash from the Transactions are expected to be used for (i) dividend distribution to Shareholders with reference to the Company's results of operations, capital expenditures and cash flows in 2020 (the distribution plan will be contained in the relevant interim and annual results announcements of the Company in 2020 to be published); (ii) the Group's upstream oil and gas exploration and development, and downstream business development in order to further increase the value of oil and gas industry chain, as well as the transformational development of the Company to a green and low-carbon model with more investments on the fields of new energy and new materials; and (iii) repayment of debts in order to optimize the Company's capital structure.

5. RATIONALES AND BENEFITS FOR THE TRANSACTIONS

The Transactions are carried out mainly based on commercial rationales of the Company's future long-term development.

First, as the largest oil and gas producer and supplier in the PRC, the Company is a leader in the domestic market in terms of its annual production volume of crude oil and natural gas. In particular, being a green, low-carbon and clean energy, natural gas is an important and strategic asset for the Company with expected growth potential and value. Between now and 2025, the Company will continue to develop its domestic natural gas business. In light of the expected progress in domestic energy transformation and environment protection measures, the domestic natural gas consumption volume is expected to increase between now and 2025,

13

and the Company is expected to maintain a stable market share. Upon completion of the restructuring of the Company's pipeline business, the Company will focus more on its upstream oil and gas exploration and development business, and actively promote the development of its downstream oil and gas distribution market.

Secondly, the Transactions are expected to help relieve the Company's pressure relating to capital expenditures. With the increase in domestic production of natural gas, and the increase in resources of imported natural gas, the Company would have been expected to invest more on the long-distance pipeline construction in the period from 2021 to 2030. The Company expects that the Transactions can effectively reduce the scale of the Company's pipeline investment, so as to relieve the Company's pressure relating to capital expenditures.

Thirdly, the Company would be able to make greater use of the nationwide oil and gas storage and transmission facilities to improve operational efficiency and value creation capabilities. Participating in the national pipeline network restructuring will help strengthen the strategic synergy with PipeChina in the planning, use and operation of the pipeline network. Meanwhile, according to PipeChina's development plan, with new pipelines being gradually put into operation, PipeChina has good growth potential, and is expected to bring positive financial impact on the Company, which can support the development of the Company's core businesses.

The Directors are of the view that (i) the terms of the Transactions are fair and reasonable; and (ii) the Transactions were entered into on normal commercial terms and are in the interests of the Company and the Shareholders as a whole.

6. LISTING RULES IMPLICATIONS

The Transactions involve the Proposed Disposal (in respect of the disposal of the Target Assets) and the Proposed Subscription (in respect of the subscription for equity interest in PipeChina).

As the highest of the applicable percentage ratios under the Hong Kong Listing Rules in respect of the Proposed Disposal is more than 25% but less than 75%, such transactions constitute a major transaction of the Company. As the highest of the applicable percentage ratios under the Hong Kong Listing Rules in respect of the Proposed Subscription is more than 5% but less than 25%, it constitutes a disclosable transaction of the Company.

As such, the Transactions as a whole are subject to the reporting, announcement and shareholders' approval requirements under Chapter 14 of the Hong Kong Listing Rules.

Two directors and senior management of PipeChina had served as the Directors of the Company and the senior management of CNPC, the Company's controlling Shareholder, within the past 12 months. According to the Shanghai Stock Exchange Listing Rules, PipeChina is a related legal person of the Company. As a result, the Transactions constitute a related party transaction of the Company. However, since none of the Directors are related Directors as defined under the Shanghai Stock Exchange Listing Rules, no Director is required to abstain from voting. Since CNPC is not a related Shareholder as defined under the Shanghai Stock Exchange Listing Rules, it is not required to abstain from voting at the general meeting. The Transactions do not constitute a material asset reorganization of the Company.

7. BUSINESS RELATIONSHIPS WITH PIPECHINA

On 23 July 2020, the Company entered into the Operation Agreement with PipeChina. Pursuant to the Operation Agreement, under the premise of complying with the national laws

14

and regulations, the Company and PipeChina shall cooperate closely and support each other's development in order to establish a long-term cooperation mechanism for production and operation coordination, to ensure the orderly connection and smooth operation of the oil and gas production business of the Company and the pipeline transmission business of PipeChina. The parties will coordinate with each other at the three levels, namely headquarters, production and operation command centers and regional companies. The parties shall adhere to the principles of operation management under contracts and plan consistency management; the principles of fairness and openness, compliant operations and smooth connection; and the principles of operation management innovation promoted jointly by the parties, and data sharing.

The parties have agreed under the Operation Agreement on operation coordination scope, preparation and implementation of pipeline transmission plan, operation management classification and coordination mechanism, management on crude oil, refined products, natural gas pipeline transmission, measurement handover and settlement, maintenance and repair of production equipment and facility, operation emergency coordination, data sharing, etc.

Appendix I - Report from KPMG

The following is the text of a report received from the Company's reporting accountants, KPMG, Certified Public Accountants, Hong Kong, for inclusion in this announcement.

REPORT ON THE DISCOUNTED FUTURE CASH FLOWS IN CONNECTION WITH THE ASSETS VALUATION OF THE ASSETS AND LIABILITIES RELATED TO THE PIPELINE TRANSPORTATION BUSINESS OF PETROCHINA COMPANY LIMITED

TO THE BOARD OF DIRECTORS OF PETROCHINA COMPANY LIMITED

We refer to the discounted future cash flows on which the assets valuation ("the Valuation")

dated 23 July 2020 prepared by China United Assets Appraisal Group Co., Ltd.* (中聯資產 評估集團有限公司) in respect of the appraisal of the market value of the assets and liabilities

related to the pipeline transportation business of PetroChina Company Limited (the "Target Assets") as at 31 December 2019 is based. The Valuation is prepared based in part on the discounted future cash flows and is regarded as a profit forecast under paragraph 14.61 of the Rules Governing the Listing of Securities on The Stock Exchange of Hong Kong Limited (the "Listing Rules").

Directors' Responsibilities

The directors of PetroChina Company Limited (the "Directors") are responsible for the preparation of the discounted future cash flows in accordance with the bases and assumptions determined by the Directors and as set out in the Valuation. This responsibility includes carrying out appropriate procedures relevant to the preparation of the discounted future cash flows for the Valuation and applying an appropriate basis of preparation; and making estimates that are reasonable in the circumstances.

Our Independence and Quality Control

We have complied with the independence and other ethical requirements of the Code of Ethics for Professional Accountants issued by the Hong Kong Institute of Certified Public Accountants ("HKICPA"), which is founded on fundamental principles of integrity, objectivity, professional competence and due care, confidentiality and professional behaviour.

The firm applies Hong Kong Standard on Quality Control 1 "Quality Control for Firms That Perform Audits and Reviews of Financial Statements, and Other Assurance and Related Services Engagements" issued by the HKICPA and accordingly maintains a comprehensive system of quality control including documented policies and procedures regarding compliance with ethical requirements, professional standards and applicable legal and regulatory requirements.

Reporting Accountants' Responsibilities

Our responsibility is to report, as required by paragraph 14.62(2) of the Listing Rules, on the calculations of the discounted future cash flows used in the Valuation. The discounted future cash flows do not involve the adoption of accounting policies.

23

Basis of Opinion

We conducted our engagement in accordance with the Hong Kong Standard on Assurance Engagements 3000 (Revised) "Assurance Engagements Other Than Audits or Reviews of Historical Financial Information" issued by the HKICPA. This standard requires that we plan and perform our work to obtain reasonable assurance as to whether, so far as the calculations are concerned, the Directors have properly compiled the discounted future cash flows in accordance with the bases and assumptions adopted by the Directors as set out in the Valuation. We performed procedures on the arithmetical calculations and the compilations of the discounted future cash flows in accordance with the bases and assumptions adopted by the Directors. Our work is substantially less in scope than an audit conducted in accordance with Hong Kong Standards on Auditing issued by the HKICPA. Accordingly, we do not express an audit opinion.

Opinion

In our opinion, so far as the calculations are concerned, the discounted future cash flows have been properly compiled in all material respects in accordance with the bases and assumptions adopted by the Directors as set out in the Valuation.

Other matters

Without qualifying our opinion, we draw to your attention that we are not reporting on the appropriateness and validity of the bases and assumptions on which the discounted future cash flows are based and our work does not constitute any valuation of the Target Assets or an expression of an audit or review opinion on the Valuation.

The discounted future cash flows depend on future events and on a number of assumptions which cannot be confirmed and verified in the same way as past results and not all of which may remain valid throughout the period. Further, since the discounted future cash flows relates to the future, actual results are likely to be different from the discounted future cash flows because events and circumstances frequently do not occur as expected, and the differences may be material. Our work has been undertaken for the purpose of reporting solely to you under paragraph 14.62(2) of the Listing Rules and for no other purpose. We accept no responsibility to any other person in respect of, arising out of or in connection with our work.

IV. Appraisal Assumptions

The appraisal conclusion was based on the following assumptions. Where these conditions change, the appraisal results will generally become invalid.

(I) General Assumption

1. Transaction Assumption

The transaction assumption assumes that all assets to be appraised are already in the process of transaction, and we simulate the market for appraisal under the transaction conditions of the assets to be appraised. The transaction assumption is one of the most basic pre-conditional assumptions for the performance of asset appraisal.

2. Public Market Assumption

The public market assumption assumes that, as for the assets traded in the market, or the assets to be traded in the market, both trading parties of asset earn equal position and have the

29

same opportunities and time to obtain sufficient market information, so as to make rational judgment on the functions, usage and transaction prices of the assets. The public market assumption is based on the fact that the assets are able to be publicly traded on the market.

3. Sustainable Operation Assumption

The sustainable operation assumption refers to such an assumption that, the subject assets will be continuously operated as per its current purpose and the function, size, frequency and environment of use, or continue to be used on the basis of certain change therein, and we determine the method, parameters and basis for appraisal accordingly.

(II) Special Assumptions

  1. There is NO significant change in the current macroeconomic, financial and industrial policies of China;
  2. There is NO significant change in other social and economic environment where the Appraisal Subject is located and other policies (such as tax policies and tax rates) implemented thereby;
  3. The future operation and management team of the Appraised Subject will be diligent on their duties, and continue to follow the existing operation plans to operate the Appraisal Subject.
  4. All assets in this appraisal are based on the actual existing amount as of the Appraisal Base Date, and the current market price of relevant assets is based on the effective price on the domestic market as of the Appraisal Base Date;
  5. The basic data/information and financial data/information provided by the client and appraised entities are true, accurate and complete;
  6. The Appraisal Scope is only subject to and based on the scope specified in the appraisal declaration forms provided by the client and appraised entities, without taking into account the contingent assets and contingent liabilities that may exist outside the scope provided by the client and appraised entities;
  7. Given the frequent or significant changes of the cash or bank deposits of appraised entities in daily operation, when evaluating the financial expenses, we did not take into account the interest income generated by the deposits, nor consider the uncertain gains or losses such as exchange gains and losses.
  8. We assuming that the cash inflow and cash outflow of the appraised entities after the Appraisal Base Date are average inflow and outflow.
  1. Brief Introduction to Appraisal Methods
  1. Brief Introduction to the Asset-based Method

The asset-based method refers to the appraisal approaches to determine the value of the appraised subject on the basis of reasonably appraising the value of various assets and liabilities. The appraisal methods for the main assets and liabilities are as follows:

(1) Long-term equity investment

Based on necessary checking and verification, considering the specific conditions of various

30

long-term equity investments, we adopted the asset-based method and the income method, respectively, to appraise the overall assets of the share-holding entities, and then multiplied the appraisal value of the net assets of the invested entities on the Appraisal Date by the shareholding proportion of PetroChina, to calculate and determine the appraisal value of long-term equity investment.

Appraisal value of long-term equity investment = appraisal value of net assets of the invested entity × shareholding ratio

When determining the appraisal value of long-term equity investment, we did not take into account the premium and discount caused by such factors as controlling shares and minority shares, and did not take into account the impact from equity liquidity on the appraisal results.

(2) Fixed assets - long-distance oil and gas pipelines

We adopted the replacement cost method to appraise the assets of long-distance oil and gas pipelines.

Appraisal value = full price for replacement × residue rate

  • Determination of full price for replacement

Full price for replacement = main material expenses (tax exclusive) + construction expenses (tax exclusive) + preliminary expenses (tax exclusive) + compensation expenses + capital cost

A. Main material expenses

Main material expenses = Σ Material consumption × Unit price of material

B. Construction expenses

In this appraisal, we adopted the actual settlement data adjustment approach for the projects with complete final (settlement) accounting data, which determines the replacement cost on the appraisal base date after price difference adjustment based on project settlement data. For some assets with missing project data, we adopted the estimated consumption index adjustment approach, which refers to the unit project consumption under similar pipe diameter, topography and construction conditions, and determining the replacement cost on the appraisal date after price difference adjustment based on the current market unit prices; or, we adopted the building element price index adjustment approach, which makes statistical and comparative analysis of the proportions of manpower, materials and machines in the existing pipeline settlement data, and then determining the project cost change index.

C. Preliminary expenses and other expenses

The preliminary and other expenses include the construction expenses required and charged by the local government and other expenses invested by the construction entity for the construction project except the construction and installation costs. Refer to the relevant regulations and cost calculation procedures issued by the State Planning Commission of the PRC and the Ministry of Construction of the PRC as well as local regulations.

D. Compensation expenses

In this appraisal, as for the compensation expenses, we calculated the necessary costs on the appraisal base date by the land price index adjustment approach.

E. Capital cost

31

Capital cost is the financing cost of the funds occupied during the ordinary construction period of buildings, namely, the interest calculated according to the bank loan interest rate of the same period executed on the Appraisal Base Date.

  • Residue rate

By conducting on-field diligence, we understood the working environment and existing technical situation of long-distance pipelines, consulted recent technical data, relevant repair records, operation records and periodic inspection reports, etc., and combined with industry experience and statistical data, determined the remaining service life and determined the residue rate. The calculation formula is:

Residue rate = Remaining service life/ (Remaining service life + Used life) × 100%

(3) Intangible assets - land use right

According to the requirements of the Practice Standards for Assets Appraisal-Real Estate and the Regulations for Valuation on Urban Land, combined with the location, land use nature, utilization conditions and local land market conditions of the Appraised Entity, we analyzed the applicability of different appraisal methods, and finally chose the market comparison approach, the benchmark land price coefficient correction approach and the cost approximation approach for appraisal.

  • Market Comparison Approach: according to the principle of substitution in the market, we compared the land parcel to be appraised with the similar land use rights which are substitutable and traded in the market on recent dates close to the appraisal date, and made appropriate amendments to the transaction prices of similar land use rights, so as to estimate the objective and reasonable price of the land parcel to be appraised.
  • Benchmark Land Price Coefficient Correction Approach: we used the appraisal results such as urban benchmark land prices and the table of benchmark land price correction coefficients, compared the regional conditions and individual conditions of the land parcel to be appraised with the average conditions of the subject region according to the principle of substitution, and selected the corresponding correction coefficient according to the correction coefficient table to correct the benchmark land price, and then obtained the price of the land parcel to be appraised on the appraisal date.
  • Cost Approximation Approach: We determined the land price based on the sum of various objective costs for land development, plus objective profits, interest, taxes payable and land appreciation.

(4) Liabilities

We checked and verified the actual debtors and debt amounts of various liabilities after exercising the appraisal purpose, and determined the appraisal value according to the items and amounts of liabilities that the property owner actually needs to bear after exercising the appraisal purpose.

(II) Brief Introduction to the Income Method

1. Overview

In this appraisal, we predicted the net assets value of the appraised entities by adopting the discounted cash flow method (DCF) according to the income approaches.

32

DCF is a method to appraise the asset value by converting the expected future net cash flows of an appraised entity to a present value. This method aims to obtain the appraisal value by predicting the expected future net cash flows of the assets and converting it into a present value by adopting an appropriate discount rate. The basic conditions for its application: an appraised entity has the foundation and conditions for sustainable operation; there is a relatively stable correspondence between operation and income, and the future income and risks can be predicted and quantified.

Appraisal Model

(1)

Basic Model

The basic model for this appraisal is:

E = B D

(1)

Wherein:

  1. Value of all shareholders' equity (net assets) of Appraised Entity;
  1. Enterprise value of Appraised Entity;

B = P + I + C

(2)

  1. Value of interest-bearing debts of Appraised Entity;
  1. Value of operating assets of Appraised Entity;

n

Ri

P =

(1 + r)i

i=1

(3)

Wherein:

Ri: Expected earnings of the ith year in future (free cash flows) of Appraised Entity;

r: Discount rate;

n: Future operating period of Appraised Entity;

  1. Value of surplus or non-operating assets (liabilities) of Appraised Entity existing on the base date;

C =C1+C2

(4)

C1: Value of current surplus or non-operating assets (liabilities) of Appraised Entity existing on the base date;

C2: Value of non-current surplus or non-operating assets (liabilities) of Appraised Entity existing on the base date;

I: Value of long-term equity investment of an appraised entity.

(2) Income Indicators

33

In this appraisal, we used the free cash flows of an appraised entity as the income indicator of the operating assets of the appraised entity, which is defined as:

R = Net profit

+ Depreciation and amortization + Interest on interest-bearing debts after

deducting taxes - Additional capital

(5)

According to the business history and future market development of an appraised entity, we predicted its free cash flows in the future operation period. We discounted and summed up the free cash flows in the future operation period, to calculate the value of operating assets of an appraised entity.

(3) Discount Rate

In this appraisal, we determined the discount rate (r) by adopting the Weighted Average Cost of Capital (WACC) model:

r = rd × wd + re × we

(6)

Wherein:

Wd : Debt ratio of Appraised Entity;

wd

=

D

(E + D)

(7)

We : Equity ratio of Appraised Entity;

we

=

E

(E + D)

(8)

rd : Interest rate of interest-bearing debts after income tax;

re : Cost of equity capital; In this appraisal, cost of equity capital (re) was determined by the Capital Asset Pricing Model (CAPM);

re = rf

+ βe × (rm

rf

) + ε

(9)

Wherein:

rf : Risk-free rate of return;

rm : Expected return of the market-;

ε : Characteristic risk adjustment factor of Appraised Entity;

βe : Expected market risk factor of the equity capital of Appraised Entity;

β e = βu × (1 + (1 − t) × D )

E(10)

βu : Expected unlevered market risk factor of comparable companies;

34

βu

=

βt

1 + (1 − t)

Di

Ei

(11)

βt : Expected market average risk factor of stocks (assets) of comparable companies;

βt = 34%K + 66%β x

(12)

Wherein:

K: Average value at risk of expected stock market in the future, normally it is assumed that K=1;

βx: Historical market average risk factor of stocks (assets) of comparable companies;

Di, Ei : Interest-bearing liabilities and equity capital of comparable companies, respectively.
