Our consolidated financial statements are reported in Renminbi and prepared in conformity with International Financial Reporting Standards as issued by the International Accounting Standards Board (“IFRS”). Totals presented in this Annual Report may not correctly total due to rounding of numbers. References to a particular fiscal year are to the period ended December 31 of such year.

The audited consolidated financial statements as at and for the years ended December 31, 2016, 2017 and 2018 included in this Annual Report reflect the first year of adoption of standards IFRS 15 — Revenue from Contracts with Customers (“IFRS 15”). The transition was applied by using a full retrospective method from January 1, 2016. Changes in accounting policy applied as a result of the adoption including the restatements of the consolidated statements of financial position as at December 31, 2017 and January 1, 2017, and the related consolidated statements of profit or loss, comprehensive income, changes in equity and cash flows for the period ended December 31, 2017 and 2016. The effects of adopting IFRS 15 are described in Note 2.4 to the accompanying consolidated financial statements included in this Annual Report. The audited consolidated financial statements as at and for the years ended December 31, 2015 and 2014 were not restated for the retrospective application of IFRS 15. In addition, the financial and operational data as at and for the years ended December 31, 2016, 2017 and 2018 included in this Annual Report reflect Yuchai’s revision of its classification system for light-, medium- and heavy-duty engines implemented in 2018. Under the revised classification system, light-duty engines have engine capacity of 3.8 liters or less; medium-duty engines have engine capacity of between 3.8 liters and 7.0 liters; and heavy-duty engines have engine capacity of more than 7.0 liters. In addition to engine capacity, the new classification system takes into account the commercial application of the engines by original equipment manufacturers. For example, certain 4-cylinder engines that were previously classified as light-duty engines have been reclassified as medium-duty engines to the extent that they have application in the light- and medium-duty segments.

Selected Financial Data

The selected consolidated statement of financial position data as of December 31, 2017 and 2018, and the selected consolidated statement of profit or loss data and the selected consolidated statement of cash flows data set forth below for the years ended December 31, 2016, 2017 and 2018 are derived from our audited consolidated financial statements included in this Annual Report. The selected consolidated statement of financial position data as of December 31, 2014, 2015 and 2016, and the selected consolidated statement of profit or loss data and the selected consolidated statement of cash flows data set forth below for the years ended December 31, 2014 and 2015 are derived from our audited consolidated financial statements not included in this Annual Report. Our consolidated financial statements as of and for the years ended December 31, 2014, 2015, 2016, 2017 and 2018 have been prepared in conformity with IFRS.

The audited consolidated financial statements as of and for the years ended December 31, 2016, 2017 and 2018 included in this Annual Report reflect the first year of adoption of standards IFRS 15. In addition, the financial and operational data as of and for the years ended December 31, 2016, 2017 and 2018 included in this Annual Report reflect Yuchai’s revision of its classification system for light-, medium- and heavy-duty engines implemented in 2018. For more information, see “Certain Definitions and Supplemental Information.”

The selected financial information as of and for the years ended December 31, 2016, 2017 and 2018 set forth below should be read in conjunction with, and is qualified in its entirety by reference to “Item 5. Operating and Financial Review and Prospects” and our audited consolidated financial statements and the notes thereto.

We currently own, through six of our wholly-owned subsidiaries, 76.4% of the outstanding shares of Yuchai. Our ownership interest in Yuchai is our main business asset. As a result, our financial condition and results of operations depend primarily upon Yuchai’s financial condition and results of operations, and the implementation of the Reorganization Agreement, as amended by the Cooperation Agreement.

Following an announcement in February 2005 by the Board of Directors of the Company of its approval of the implementation of our business expansion and diversification plan, we looked for new business opportunities to seek to reduce our financial dependence on Yuchai. As of December 31, 2018, we had a 48.9% interest in the outstanding ordinary shares of HLGE and a 7.7% interest in the outstanding ordinary shares of TCL. As of February 28, 2019, our interest in the outstanding ordinary shares of HLGE and TCL remained unchanged.

Relating to our interest in HLGE:

On January 13, 2012, our wholly-owned subsidiary, Grace Star Services Limited (“Grace Star”) transferred 24,189,170 Series B redeemable convertible preference shares in the capital of HLGE (the “Trust Preference Shares”) to Amicorp Trustees (Singapore) Limited (the “Trustee”) pursuant to a trust deed entered into between HLGE and the Trustee (the “Trust”). On January 16, 2012, the Trust Preference Shares were mandatorily converted into 24,189,170 new ordinary shares in the capital of HLGE (the “Trust Shares”) resulting in our shareholding interest in HLGE decreasing from 49.4% to 48.1%. On April 4, 2012, as a result of the conversion of all the outstanding Series A redeemable convertible preference shares held by our wholly-owned subsidiaries, Venture Delta Limited (“Venture Delta”) and Grace Star, into new ordinary shares in the capital of HLGE, our shareholding interest in HLGE increased from 48.1% to 48.9%.

The Trust Shares are accounted for as treasury shares by HLGE as they are issued by HLGE and held by the Trust, which is considered as part of HLGE. As a result, based on the total outstanding ordinary shares of HLGE net of the Trust Shares, our shareholding interest in HLGE is stated as 50.2% for accounting purposes in the Company’s consolidated financial statements for the year ended December 31, 2018. However, these Trust Shares are not regarded as treasury shares under the Singapore Companies Act, Chapter 50, and the Trustee has the power, inter alia, to vote or abstain from voting in respect of the Trust Shares at any general meeting of HLGE in its absolute discretion and to waive its right to receive dividends in respect of the Trust Shares as it deems fit. Accordingly, based on the total outstanding ordinary shares of HLGE including the Trust Shares, our shareholding interest in HLGE is 48.9% as of December 31, 2018 and February 28, 2019. We consolidate the results of HLGE as a subsidiary. See Note 1.3 to the accompanying consolidated financial statements in Item 18.

Relating to our interest in TCL:

Since fiscal year 2010, we have gradually reduced our total shareholding in TCL. Our total shareholding interest in TCL was 7.7% as of December 31, 2018 and February 28, 2019. We classify our shareholding in TCL as quoted equity securities. On March 27, 2019, W Capital Markets Pte. Ltd., for and on behalf of Prime Trade Enterprises Limited, an investment holding company ultimately owned and controlled by certain members of the Thakral family, announced a voluntary conditional cash partial offer to acquire approximately 20% of the total issued shares of TCL. We are currently considering our options in relation to our investment in the TCL group including disposing of our entire shareholding in TCL.

For further information on the Company’s investments in HLGE and TCL, see “Item 5. Operating and Financial Review and Prospects — Business Expansion and Diversification Plan.”

Dividends

Our principal source of cash flow has historically been our share of the dividends, if any, paid to us by Yuchai, as described under “Item 5. Operating and Financial Review and Prospects — Liquidity and Capital Resources.”

In May 1993, in order to finance further expansion, Yuchai sold shares to the Company, or Foreign Shares, and became a Sino-foreign joint stock company.

Chinese laws and regulations applicable to a Sino-foreign joint stock company require that before Yuchai distributes profits, it must (i) recover losses in previous years; (ii) satisfy all tax liabilities; and (iii) make contributions to the statutory reserve fund in an amount equal to 10% of net income for the year determined in accordance with generally accepted accounting principles in the PRC, or PRC GAAP. However, the allocation of statutory reserve fund will not be further required once the accumulated amount of such fund reaches 50% of the registered capital of Yuchai.

Any determination by Yuchai to declare a dividend will be at the discretion of Yuchai’s shareholders and will be dependent upon Yuchai’s financial condition, results of operations, regulatory factors and other relevant factors. Yuchai’s Articles of Association provide that dividends shall be paid at least once a year out of after-tax profits (if any). To the extent Yuchai has foreign currency available, dividends declared by shareholders at a shareholders’ meeting to be paid to holders of Foreign Shares (currently only us) will be payable in foreign currency, and such shareholders will have priority thereto. If the foreign currency available is insufficient to pay such dividends, such dividends may be payable partly in Renminbi and partly in foreign currency. Dividends allocated to holders of Foreign Shares may be remitted in accordance with the relevant Chinese laws and regulations. In the event that the dividends are distributed in Renminbi, such dividends may be converted into foreign currency and remitted in accordance with the relevant Chinese laws, regulations and policies.

Any determination by the Company to declare a dividend will be at the discretion of our board of directors and will be dependent upon our financial condition, results of operations and other relevant factors. The following table sets forth a five-year summary of dividends we have paid to our shareholders as well as dividends paid to us by Yuchai:

Risk Factors

Risks relating to our shares and share ownership

Our controlling shareholder’s interests may differ from those of our other shareholders.

As of February 28, 2019, our controlling shareholder, Hong Leong Asia Ltd., or Hong Leong Asia, indirectly owns 17,059,154 or approximately 41.75%, of the outstanding shares of our Common Stock, as well as a special share that entitles it to elect a majority of our directors. Hong Leong Asia controls us through its wholly-owned subsidiary, Hong Leong (China) Limited, or Hong Leong China, and through HL Technology Systems Pte Ltd, or HL Technology, a wholly-owned subsidiary of Hong Leong China. HL Technology owns approximately 23.30% of the outstanding shares of our Common Stock and has, since August 2002 been the registered holder of the special share. Hong Leong Asia also owns, through another wholly-owned subsidiary, Well Summit Investments Limited, approximately 18.45% of the outstanding shares of our Common Stock as of February 28, 2019. Hong Leong Asia is a member of the Hong Leong Investment Holdings Pte. Ltd., or Hong Leong Investment group of companies. Prior to August 2002, we were controlled by Diesel Machinery (BVI) Limited, or Diesel Machinery, which, until its dissolution, was a holding company controlled by Hong Leong China and was the prior owner of the special share. Through HL Technology’s stock ownership and the rights accorded to the Special Share under our Bye-Laws and various agreements among shareholders, Hong Leong Asia is able to effectively approve and effect most corporate transactions. See “Item 7. Major Shareholders and Related Party Transactions — Related Party Transactions — Shareholders Agreement.” In addition, our shareholders do not have cumulative voting rights. There can be no assurance that Hong Leong Asia’s actions will be in the best interests of our other shareholders. See also “Item 7. Major Shareholders and Related Party Transactions — Major Shareholders.”

We may experience a change of control as a result of sale or disposal of shares of our Common Stock by our controlling shareholders.

As described above, HL Technology, a subsidiary of Hong Leong Asia, owns 9,520,251 shares of our Common Stock, as well as the special share. If HL Technology reduces its shareholding to less than 7,290,000 shares of our Common Stock, our Bye-Laws provide that the special share held by HL Technology will cease to carry any rights, and Hong Leong Asia may as a result cease to have control over us. See “Item 7. Major Shareholders and Related Party Transactions — The Special Share.” If HL Technology sells or disposes of all of the shares of our Common Stock, we cannot determine what control arrangements will arise as a result of such sale or disposal (including changes in our management arising therefrom), or assess what effect those control arrangements may have, if any, on our financial condition, results of operations, business, prospects or share price.

In addition, certain of our financing arrangements have covenants requiring Hong Leong Asia to retain ownership of the special share and that we remain a principal subsidiary (as defined in such arrangements) of Hong Leong Asia. A breach of that covenant may require us to pay all outstanding amounts under those financing arrangements. There can be no assurance that we will be able to pay such amounts or obtain alternate financing.

The market price for our Common Stock may be volatile.

There continues to be volatility in the market price for our Common Stock. See “Item 9. The Offer and Listing.” The market price could fluctuate substantially in the future in response to a number of factors, including:

8

Any of the above factors either individually or together may result in market fluctuations which may materially adversely affect our stock price.

We may be classified as a passive foreign investment company, which could result in adverse United States federal income tax consequences to US Holders.

A non-United States corporation is considered a passive foreign investment company, or PFIC, for United States federal income tax purposes for any taxable year if either (1) at least 75% of its gross income is passive income or (2) at least 50% of the total value of its assets (based on an average of the quarterly values of the assets during a taxable year) is attributable to assets that produce or are held for the production of passive income. For this purpose, the total value of our assets generally will be determined by reference to the market price of our shares. We believe that our shares should not be treated as stock of a PFIC for United States federal income tax purposes for the taxable year ended on December 31, 2018. However, there is no guarantee that the United States Internal Revenue Service will not take a contrary position or that our shares will not be treated as stock of a PFIC for any future taxable year. Our PFIC status will be affected by, among other things, the market value of our shares and the assets and operations of our company and subsidiaries. If we were to be treated as a PFIC for any taxable year during which a US Holder (defined below) holds our shares, certain adverse United States federal income tax consequences could apply to the US Holder. See “Item 10. Additional Information — Taxation — United States Federal Income Taxation — PFIC Rules.”

If a United States person is treated as owning at least 10% of our shares, such holder may be subject to adverse U.S. federal income tax consequences.

If a United States person is treated as owning (directly, indirectly or constructively) at least 10% of the value or voting power of our Common Stock, such person may be treated as a “United States shareholder” with respect to each “controlled foreign corporation” in our group (if any). If our group includes one or more U.S. subsidiaries, under recently-enacted rules, certain of our non-U.S. subsidiaries could be treated as controlled foreign corporations regardless of whether we are or are not treated as a controlled foreign corporation (although there is currently a pending legislative proposal to significantly limit the application of these rules). A United States shareholder of a controlled foreign corporation may be required to annually report and include in its U.S. taxable income its pro rata share of “Subpart F income”, “global intangible low-taxed income” and investments in U.S. property by controlled foreign corporations, whether or not we make any distributions. An individual that is a United States shareholder with respect to a controlled foreign corporation generally would not be allowed certain tax deductions or foreign tax credits that would be allowed to a United States shareholder that is a U.S. corporation. A failure to comply with these reporting obligations may subject you to significant monetary penalties and may prevent the statute of limitations with respect to your U.S. federal income tax return for the year for which reporting was due from starting. We cannot provide any assurances that we will assist investors in determining whether any of our non-U.S. subsidiaries are treated as a controlled foreign corporation or whether such investor is treated as a United States shareholder with respect to any of such controlled foreign corporations or furnish to any United States shareholders information that may be necessary to comply with the aforementioned reporting and tax paying obligations. A United States investor should consult their own advisors regarding the potential application of these rules to its investment in the Common Stock.

Risks relating to our company and our business

The diesel engine business in China is dependent in large part on the performance of the Chinese and the global economy. As a result, our financial condition, results of operations, business and prospects could be adversely affected by slowdowns in the Chinese and the global economy.

Our operations and performance depend significantly on worldwide economic conditions. During periods of economic expansion, the demand for trucks, construction machinery and other applications of diesel engines generally increases. Conversely, uncertainty about current global economic conditions or adverse changes in the economy could lead to a significant decline in the diesel engine industry which is generally adversely affected by a decline in demand. According to the World Bank’s Global Economic Prospects issued in January 2019, global economic growth is projected to remain soft, expanding at a rate of 2.9% in 2019 amid increasing downside risk to the outlook. Growth among advanced economies is forecast to drop to 2% in 2019. While slowing external demand and persistent policy uncertainties are expected to weigh on the outlook for emerging markets and developing economies, growth for this group is anticipated to reach 4.2% in 2019.

In the Eurozone, large uncertainty still surrounds the United Kingdom’s withdrawal from the EU (known as BREXIT) and risk of economic weakness in some EU member states remains. According to its Winter European Economic Forecast issued on February 7, 2019, the European Commission anticipates economic growth in the Eurozone to continue but at a slower pace, with expected economic growth in 2019 being revised lower to 1.6%.

The current political climate has introduced greater uncertainty with respect to trade policies, tariffs and government regulations affecting trade between the U.S. and China. In March 2018, the Trump administration announced import tariffs on steel and aluminum, including imports from China where our operations are primarily located. The effect of this policy, and the possibility and extent of any international trade conflicts, particularly trade conflicts between the U.S. and China, and such conflict’s impact, if any, on our business or results of operations is uncertain. In addition, the performance of the Chinese economy affects, to a significant degree, our financial condition, results of operations, business and prospects. For example, the various measures taken by the Chinese government from time to time to regulate economic growth and control inflation have in prior periods, significantly weakened demand for trucks in China, and may have a similar effect in the future. Uncertainty and adverse changes in the Chinese economy could also increase costs associated with developing our products, increase the cost and decrease the availability of potential sources of financing, and increase our exposure to material losses from our investments, any of which could have a material adverse impact on our financial condition and operating results.

According to the National Bureau of Statistics, China’s GDP grew by 6.6% in 2018, compared with 6.8% in 2017. Although the growth slowdown in China continues to be gradual in response to the Chinese government’s planned reform of the economy, there are downside risks to growth. The main short-term risk is the unwinding of high leverage in sectors with excess capacity, namely the manufacturing, industrial and real estate sectors. This may result in a sharper-than-expected slowdown in investment and hence in aggregate demand. There have been increasing concerns over China’s current debt levels which continue to trend upwards despite decelerating credit growth which has resulted in fears over possible defaults by local banks, corporate entities including state-owned enterprises and local provincial governments. In March 2019 in the Chinese government’s Work Report announced at the National People’s Congress in Beijing, Premier Li Keqiang lowered China’s 2019 GDP growth target to a range of 6.0% to 6.5%, citing more complex risks and challenges in the coming year, including ongoing trade disputes with the U.S.. To help domestic businesses, the Chinese government also announced a reduction in the value-added tax rate (“VAT”) for manufacturers from 16% to 13%, and VAT for construction and transport companies from 10% to 9%. The business and prospects for the diesel engine industry, and thus the business and prospects of our company, may be adversely affected by changes in Chinese government policies.

Further, as a result of recurring liquidity tightening in the banking system, alternative lending and borrowing outside of traditional banking practices, generally known as “shadow banking”, has grown to become an integral and significant aspect of the Chinese economy. Such alternative lending is loosely regulated and has led to an increase in China’s debt levels leading to concern over rising bad debts and financial problems. As an increasing portion of the funds obtained from shadow banking are being used for investments in speculative and risky products or assets, should a widespread default on such investments occur, this could harm the growth prospects of the Chinese economy. While there has been increased scrutiny and oversight by regulators, this has not entirely eradicated the shadow banking industry in China. Even if the Chinese government increases regulation over such alternative lending and borrowing, there is no assurance that such regulations will be successful, or that they would not have an adverse impact on the overall loan markets and liquidity in China, which will negatively impact the Chinese economy.

The diesel engine business in China is dependent in large part on Chinese government policy. As a result, our financial condition, results of operations, business and prospects could be adversely affected by Chinese government policies.

Our business is dependent on the state of the commercial vehicle market in China. According to CAAM, the sales of commercial vehicles have experienced fluctuations over the years primarily as a result of government incentives and subsidies introduced from time to time as well as the replacement cycle of commercial vehicles. In 2016, commercial vehicle sales (excluding gasoline powered and electric powered vehicles) were 2.7 million units, an increase of 8.3% compared with 2015, primarily due to an increase of 11.6% in the truck market as stricter enforcement of anti-overloading regulations had resulted in higher sales, which was partially offset by a 9.9% decline in sales in the bus segment compared with 2015. In 2017, commercial vehicle sales (excluding gasoline powered and electric powered vehicles) were 3.1 million units, an increase of 16.9% compared with 2016, primarily due to an increase of 19.5% in the truck market as stricter enforcement of anti-overloading regulations and increasing demand in logistics services resulted in higher sales. The bus market remained weak experiencing a 0.7% decline in overall sales with heavy-duty bus sales up 0.1% compared with 2016. In 2018, the diesel engine market was affected by factors such as the weakening influence of the Chinese government’s anti-loading policy, a “Blue Sky Protection” campaign launched by Chinese government, diminishing use of the trans-cities highway transportation system in favor of rail transport and the forthcoming implementation of National VI emission standards. In 2018, commercial vehicle sales (excluding gasoline-powered and electric-powered vehicles) were 3.1 million units, being flat compared with 2017. The truck market decreased by 1.3%, mainly attributed to a 22.3% decline in the medium-duty segment, which was partially offset by the growth of 2.7% in the heavy-duty segment. The bus market continued to weaken in 2018, resulting in a 5.3% decline in bus sales compared to 2017. The Chinese government introduced generous incentives to encourage purchases of electric-powered vehicles to curb air pollution in major cities, resulting in increased sales of electric-powered commercial vehicles, particularly in the light-duty engine vehicles segment. As a result of these initiatives, combustion bus engine sales volume in China and our share of the bus market have gradually decreased. For more details, see “— Increasing demand for electric vehicles may lead to decreases in demand for our engines affecting our market share and profitability” and “Item 5. Operating and Financial Review and Prospects — Overview.”

In recent years, the policies of the Chinese government have encouraged energy conservation and emissions reduction. On November 19, 2014, the State Council unveiled a new Energy Development Strategy Action Plan (2014 -2020) focusing on the development of renewables and limiting its primary energy consumption growth rate to 3.5% per year until 2020. Premier Li Keqiang in his 2017 annual policy report acknowledged the continued concerns over environmental pollution and stated that the Chinese government would increase the pace of progress to improve the environment, especially air quality. The measures to be adopted include tackling the sources of pollution in key industries, strengthening control over exhaust emitted by motor vehicles through the prohibition of use of higher emission vehicles, improving the quality of fuel and promoting the use of clean energy vehicles and the strict enforcement of environment laws and regulations. China’s 13th Five Year Plan covering the years 2016 to 2020, which was formerly adopted at the National People’s Congress in Beijing in March 2016 seeks to reduce energy consumption by 15% and carbon emissions by 18% by 2020. On March 11, 2016, China’s Environment Minister announced a set of major reforms of China’s environmental management and governance system to strengthen enforcement of related environmental protection laws. The reforms are being phased in on a pilot basis in 17 provinces and autonomous regions. As part of the reforms, in 2016, the State Council dispatched central environmental inspection teams made up of ministerial level officials to 15 provincial areas, including Beijing, Shanghai and Guangzhou, to monitor local conditions and encourage provincial governments to fulfill their environmental protection responsibilities, resulting in disciplinary actions against a number of government officials and the imposition of fines for environmental violations. In addition, in February 2017, China’s Environment Minister announced a month-long special inspection on air quality across Beijing and Tianjin municipalities and Hebei, Shanxi, Shandong and Henan provinces to check on the implementation of pollution control measures by both local governments and companies. On April 10, 2017, the Ministry of Environmental Protection issued its 13th Five-Year Plan for National Environmental Protection Standards. The Plan calls for the amendment of existing environmental protection standards and the implementation of new environmental protection standards, including in relation to air quality and pollution emission control, environment detection and basic environment standards and environmental management standards. On November 15, 2018, the Ministry of Ecology and Environment (formerly known as the Ministry of Environmental Protection) announced that the Chinese government would implement a system that localizes environmental monitoring, supervision, and law enforcement activities below the provincial level under the supervision of environmental protection authorities at higher levels of government. The system is expected to be implemented in 2019.

Although a series of policy and reform measures have been formulated to create a sustainable environment for the rapid growth of the energy saving and environmental protection industry, there is no assurance that these measures will be successful. We cannot assure you that the Chinese government will not change its policies in the future. Such policy changes may de-emphasize the use of diesel engines and encourage increased use of cleaner energy alternatives, and any such changes will adversely affect our financial condition, results of operations, business or prospects. The government incentive schemes have, from time to time contributed to an increase in our engine sales in the past. However, since government incentive schemes may be changed from time to time, there can be no assurance that sales of our engines will continue to grow at the same rate as in the past or at all.

Our financial condition, results of operations, business and prospects may be adversely affected if we are unable to implement the Reorganization Agreement and the Cooperation Agreement.

We own 76.4% of the outstanding shares of Yuchai, and one of our primary sources of cash flow continues to be our share of the dividends, if any, paid by Yuchai and investment earnings thereon. As a result of the agreement reached with Yuchai and its related parties pursuant to the July 2003 Agreement, we discontinued legal and arbitration proceedings initiated by us in May 2003 relating to difficulties with respect to our investment in Yuchai. In furtherance of the terms of the July 2003 Agreement, we, Yuchai and Coomber Investments Limited, or Coomber, entered into the Reorganization Agreement in April 2005, as amended in December 2005 and November 2006, and agreed on a restructuring plan intended to be beneficial to our shareholders. In June 2007, we, along with Yuchai, Coomber and the State Holding Company, entered into the Cooperation Agreement. The Cooperation Agreement amends certain terms of the Reorganization Agreement and as so amended, incorporates the terms of the Reorganization Agreement. Pursuant to the amendments to the Reorganization Agreement, the Company has agreed that the restructuring and spin-off of Yuchai will not be effected, and, recognizing the understandings that have been reached between the Company and the State Holding Company to jointly undertake efforts to expand the business of Yuchai, the Company will not seek to recover the anti-dilution fee of US$20 million that was due from Yuchai. For more information on these agreements see “Item 4. Information on the Company — History and Development.” No assurance can be given as to when the business expansion requirements relating to Yuchai as contemplated by the Reorganization Agreement and the Cooperation Agreement will be fully implemented, or that implementation of the Reorganization Agreement and the Cooperation Agreement will effectively resolve all of the difficulties faced by us with respect to our investment in Yuchai.

In addition, the Reorganization Agreement contemplates the continued implementation of our business expansion and diversification plan adopted in February 2005. One of the goals of this business expansion and diversification plan is to reduce our financial dependence on Yuchai. Subsequently, we acquired strategic stakes in TCL and HLGE. See “Item 5. Operating and Financial Review and Prospects — Business Expansion and Diversification Plan.” Nonetheless, no assurance can be given that we will be able to successfully expand and diversify our business. We may also not be able to continue to identify suitable acquisition opportunities, or secure funding to consummate such acquisitions or successfully integrate such acquired businesses within our operations. Any failure to implement the terms of the Reorganization Agreement and Cooperation Agreement, including our continued expansion and diversification, could have a material adverse effect on our financial condition, results of operations, business or prospects. Additionally, although the Cooperation Agreement amends certain provisions of the Reorganization Agreement and also acknowledges the understandings that have been reached between us and the State Holding Company to jointly undertake efforts to expand and diversify the business of Yuchai, no assurance can be given that we will be able to successfully implement those efforts or as to when the transactions contemplated therein will be consummated.

Tariffs on certain imports into the United States and China, and other potential changes to tariff and import/export regulations may have a negative effect on global economic conditions and our business, financial results and financial condition.

Our operations expose us to the risk that increased trade protectionism will adversely affect our business. In the United States, there is significant uncertainty about the future relationship between the United States and other exporting countries, including with respect to trade policies, treaties, government regulations and tariffs. Trade tensions between the U.S. and China have resulted in both governments imposing tariffs, and both countries have indicated that they are willing to continue employing aggressive tactics, such as the imposition of additional punitive tariffs. As an example of such restrictions, since July 2018, the U.S. has imposed a 25% tariff on steel and a 10% tariff on aluminum imported into the United States, with temporary or permanent exemptions granted for certain countries. In response to these tariffs, China, the E.U., and other countries have implemented or are evaluating the use of retaliatory measures, which could further increase barriers to trade. Any increased trade barriers or restrictions on trade, especially trade with China, could depress economic activity and restrict our access to suppliers or customers and have a material adverse effect on our business, financial condition and results of operations.

11

We have in the past and may in the future experience disagreements and difficulties with the Chinese shareholders in Yuchai.

Although we own 76.4% of the outstanding shares of Yuchai, and believe we have proper legal ownership of our investment and a controlling financial interest in Yuchai, in the event there is a dispute with Yuchai’s Chinese shareholders regarding our investment in Yuchai, we may have to rely on the Chinese legal system for remedies. The Chinese legal system may not be as effective as compared to other more developed countries, such as the United States. See “Item 3. Key Information — Risk Factors — Risks relating to China — The Chinese legal system embodies uncertainties which could limit the legal protection available to foreign investors.” We have, in the past experienced problems from time to time in obtaining assistance and cooperation of Yuchai’s Chinese shareholders in the daily management and operation of Yuchai. We have, in the past also experienced problems from time to time in obtaining the assistance and cooperation of the State Holding Company in dealing with other various matters, including the implementation of corporate governance procedures, the payment of dividends, the holding of Yuchai board meetings and the resolution of employee-related matters. Examples of these problems are described elsewhere in this Annual Report. The July 2003 Agreement, the Reorganization Agreement and the Cooperation Agreement are intended to resolve certain issues relating to our share ownership in Yuchai and the continued corporate governance and other difficulties which we have had with respect to Yuchai. As part of the terms of the Reorganization Agreement, Yuchai agreed that it would seek the requisite shareholder approval prior to entering into any material transactions (including any agreements or arrangements with parties related to Yuchai or any of its shareholders) and that it would comply with its governance requirements. Yuchai also acknowledged and affirmed the Company’s continued rights as majority shareholder to direct the management and policies of Yuchai through Yuchai’s Board of Directors. Yuchai’s Articles of Association have been amended and such amended Articles of Association as approved by the Guangxi Department of Commerce on December 2, 2009, entitle the Company to elect nine of Yuchai’s thirteen directors, thereby reaffirming the Company’s right to effect all major decisions relating to Yuchai. While Yuchai has affirmed the Company’s continued rights as Yuchai’s majority shareholder and authority to direct the management and policies of Yuchai, no assurance can be given that disagreements and difficulties with Yuchai’s management and/or Yuchai’s Chinese shareholders will not recur, including implementation of the Reorganization Agreement and the Cooperation Agreement, corporate governance matters or related party transactions. Such disagreements and difficulties could ultimately have a material adverse impact on our consolidated financial position, results of operations and cash flows.

We have previously identified material weaknesses in our internal control over financial reporting and cannot assure you that material weaknesses will not be identified in the future. Our failure to implement and maintain effective internal control over financial reporting could result in material misstatements in our financial statements which could require us to restate financial statements in the future, or cause us not to be able to provide timely financial information, which may cause investors to lose confidence in our reported financial information and have a negative effect on our stock price.

We reported material weaknesses in our internal control over financial reporting as of December 31, 2005 to 2011, and our management concluded that our disclosure controls and procedures and our internal control over financial reporting were not effective for that period. However, since the year ending December 31, 2012, we have not identified any material weaknesses in our internal control over financial reporting. Our management concluded that our disclosure controls and procedures and our internal control over financial reporting were effective as of December 31, 2012 to 2018. See “Item 15. Controls and Procedures.” Our independent registered public accounting firm has expressed an unqualified opinion on the effectiveness of our internal control over financial reporting as of December 31, 2012 to 2018.

We cannot assure you that material weaknesses or significant deficiencies in our internal control over financial reporting will not be identified in the future. Any failure to maintain or improve existing controls or implement new controls could result in material weaknesses or significant deficiencies and cause us to fail to meet our periodic reporting obligations which in turn could cause our shares to be delisted or suspended from trading on the New York Stock Exchange (“NYSE”). In addition, any such failure could result in material misstatements in our financial statements and require us to restate our financial statements and adversely affect the results of annual management evaluations regarding the effectiveness of our internal control over financial reporting. Any of the foregoing could cause investors to lose confidence in our reported financial information, leading to a decline in our share price.

We depend on and expect to continue to depend on the Dongfeng Group for a significant percentage of our sales.

Our sales are concentrated among the Dongfeng Group, which includes Dongfeng Automobile Co., Ltd., one of the largest state-owned automobile companies in China, and other major diesel truck manufacturers controlled by or affiliated with Dongfeng Automobile Co., Ltd. In 2018, sales to the Dongfeng Group accounted for 27.4% of our total revenue, of which sales to our two largest customers, Dongfeng Liuzhou Motor Co., Ltd. and Dongfeng Automobile Co., Ltd., accounted for 9.9% and 3.6%, respectively. In 2018, our sales to our top five customers, including the Dongfeng Group, accounted for 37.5% of our total revenue. Although we consider our relationship with the Dongfeng Group and the other top four customers to be good, the loss of one or more of the companies within the Dongfeng Group as a customer or any one of our other top four customers whether singly or combined together would have a material adverse effect on our financial condition, results of operations, business or prospects.

As we are dependent on the purchases made by the Dongfeng Group from us, we have exposure to their liquidity arising from the high level of accounts receivables from them. We cannot assure you that the Dongfeng Group will be able to repay all the money they owe to us. In addition, the Dongfeng Group may not be able to continue purchasing the same volume of products from us which would reduce our overall sales volume.

12

The Dongfeng Group also competes with us in the diesel engine market in China. Although we believe that the companies within the Dongfeng Group generally make independent purchasing decisions based on end-user preferences, we cannot assure you that truck manufacturers affiliated with Dongfeng Automobile Co., Ltd. will not preferentially purchase diesel engines manufactured by companies within the Dongfeng Group over those manufactured by us.

Competition in China from other diesel engine manufacturers may adversely affect our financial condition, results of operations, business or prospects.

The diesel engine industry in China is highly competitive. We compete with many other China domestic companies, most of which are state-owned enterprises. Some of our competitors have formed joint ventures with or have technology assistance relationships with foreign diesel engine manufacturers or foreign engine design consulting firms and use foreign technology that is more advanced than ours. We expect competition to intensify as a result of:

In addition, we believe that there has been excess capacity in the diesel engine industry in the past, from time to time resulting from fluctuations in market demand. For example, market demand fluctuated between 2010 and 2017 as a result of, among other things, stimulus measures announced by the Chinese government to counter the effects of the 2008 global financial crisis, investment in capacity expansion by our competitors, the phasing out of Chinese government incentives for car purchases, the introduction of policies to restrict automotive growth in Beijing and other major cities, pre-buying of commercial vehicles prior to the implementation of new emission standards in China and incentives to encourage purchases of electric-powered vehicles. For more details, see “Item 5. Operating and Financial Review and Prospects — Overview.”

Any excess capacity or decrease in demand in the diesel engine industry in the future could lead to a decrease in prices in the diesel engine market and as we and our competitors compete through lower prices, this could adversely impact our revenues, margins and overall profitability. Furthermore, if restrictions and tariffs on the import of motor vehicles and motor vehicle parts into China are reduced, foreign competition could increase significantly. An increase in competition as a result of these various factors operating singly or together may adversely affect our financial condition, results of operations, business or prospects as a result of lower gross margins, higher fixed costs or decreasing market share.

Our long-term business prospects will depend largely upon our ability to develop and introduce new or improved products in response to market demands at competitive prices. Our competitors in the diesel engine markets may be able to introduce new or improved engine models that are more favorably received by customers. Competition in the end-user markets, mainly the truck market, may also lead to technological improvements and advances that render our current products obsolete at an earlier than expected date, in which case we may have to depreciate or impair our production equipment more rapidly than planned. Failure to introduce or delays in the introduction of new or improved products at competitive prices could have a material adverse effect on our financial condition, results of operations, business or prospects.

In addition, any consolidations or alliances in our industry may result in more competition for us from the resulting larger companies. Concentration within our industry, or other potential moves by our competitors, could improve their competitive position and market share and may exert further pricing pressure on us. Any consolidation or alliances in our industry involving our key suppliers or customers may adversely affect our existing relationships and arrangements with them. The loss of one or more of our key suppliers or customers due to consolidation in our industry or otherwise could have a material adverse effect on our business, financial condition and results of operations.

China vehicle industry is experiencing changes under the Chinese government’s latest initiatives to develop energy saving and new energy vehicles. It may lead to decrease in demand for our engines affecting our market share and profitability.

In 2015, China government issued the first ten-year action plan for China to become a leading manufacturing nation, namely Made In China 2025, putting forward “energy saving and new energy vehicles” as one of the key development area in vehicle industry. New energy vehicles are defined as vehicles powered by alternative sources of energy instead of fossil fuel-powered engines, such as the diesel and natural gas engines that we produce. New energy vehicles include hybrid, pure electric vehicles, fuel cell electric vehicles and other alternative energy-powered vehicles.

The Chinese government has introduced incentives to encourage purchases of electric-powered vehicles to curb air pollution in major Chinese cities. As a result of these initiatives, combustion bus engine sales volume in China and our share of the bus market have gradually decreased. According to CAAM, the sales of electric-powered commercial vehicle increased by approximately 27.3% in 2017 to 176,980 units compared to 139,060 units in 2016. The growth rate was slower in 2018 and it witnessed a moderate growth of 5.3% to 186,377 units in 2018.

13

At the legislative session of the National People’s Congress in March 2017, the Chinese government reiterated its push for greater use of new-energy vehicles and encouraged more innovation to accelerate the sector’s development. The Chinese government announced in its March 2018 Work Report to the National People’s Congress that it would grant a three-year extension of the preferential policy for new energy vehicles and continue to explore the field of new energy vehicles. The Chinese government’s March 2019 Work Report reaffirmed that it would continue implementing preferential policies for new energy vehicles purchases. Since December 2016, China has gradually reduced subsidies for new-energy vehicles and expects to phase out all financial assistance by 2020. The Chinese government policy changes reflect the government’s determination to continue to accelerate the development of new energy automobile industry while allowing China’s commercial vehicle market to gradually shift from being “policy-driven” to “market-driven”. The entry of electric-powered vehicles into the commercial vehicle market in China is a relatively new development and is marked by new and changing technologies and evolving government regulation, industry standards and customer preferences, taking into account a variety of factors, for such vehicles compared with fossil fuel-powered vehicles. As such, it is difficult at this early stage of the market’s development in China, to predict the growth and demand prospects for such vehicles.

If the market for electric-powered vehicles continues to develop or develops more quickly than we expect, the additional competition resulted from the growing new energy vehicles development could reduce demand for our engines, which could adversely affect our business, financial condition, results of operations and prospects.

If we are not able to continually improve our existing engine products and develop new engine products or successfully enter into other markets, we may become less competitive, and our financial condition, results of operations, business and prospects will be adversely affected.

As the diesel engine industry in China is highly competitive and continues to develop, we will have to continually improve our existing engine products, develop new engine products and enter into new markets in order to remain competitive. As a result, our long-term business prospects will largely depend upon our ability to develop and introduce new or improved products at competitive prices and enter into new markets. Future products may utilize different technologies and may require knowledge of markets that we do not currently possess. Moreover, our competitors may be able to introduce new or improved engine models that are more favorably received by customers than our products or enter into new markets with an early-entrant advantage. Any failure by us to introduce, or any delays in the introduction of, new or improved products at competitive prices or entering into new markets could have a material adverse effect on our financial condition, results of operations, business or prospects.

We have entered into several joint ventures in order to expand our product portfolio. There can be no assurance that our joint ventures will be successful or profitable. We have recognized impairment losses in the past related to our investments in the joint ventures and may do so again in the future. We review our investments in these joint ventures on an ongoing basis and may take such action as is deemed strategically appropriate including but not limited to divestment and shareholding changes. We have entered into the following joint ventures:

14

In April 2007, Yuchai entered into an Equity Joint Venture Agreement with Zhejiang Geely Holding Group Co., Ltd (“Geely”) and Zhejiang Yinlun Machinery Company Limited to form two joint venture companies for the development, production and sale of the 4Y20 diesel engine and parts for passenger vehicles. In May 2012, Yuchai exited from the joint venture in Zhejiang Province and increased its stake in the other joint venture in Jining, Shandong Province (“Jining Yuchai”) through a share swap agreement that gave Yuchai a 70% shareholding in Jining Yuchai, with Geely maintaining its 30% shareholding. In September 2014, Yuchai divested its entire 70% shareholding in Jining Yuchai but continued to consolidate the financial results of Jining Yuchai as a result of various contractual arrangements that allowed Yuchai to exercise effective control over Jining Yuchai. In November 2017, Yuchai acquired the entire equity interest in Jining Yuchai from an independent third party pursuant to the irrevocable option to acquire the shares in Jining Yuchai granted to Yuchai. Accordingly, Yuchai continues to consolidate the financial results of Jining Yuchai. The technology for the 4Y20 diesel engine is owned by Jining Yuchai. In 2014, we recorded an impairment loss of RMB 60 million on the technology development costs relating to the 4Y20 engine platform. In 2015, we recorded a further impairment loss of RMB 26.7 million. No impairment was recorded in 2016 but in 2017, we recorded an impairment loss of RMB 40 million. In 2018, Jining Yuchai commenced production of 4Y20 engines in view of the market demand. As such, management currently believes that there are no indicators for further impairment. As of December 31, 2018, the accumulated impairment loss recorded on technology know-how relating to the 4Y20 engine platform was RMB 126.7 million. See “Item 5. Impairment of long-lived assets, including goodwill and intangible assets.”

We have developed natural gas engines to expand our product portfolio. There can be no assurance, however, that these activities will be profitable. Since 2013, Yuchai has produced a full portfolio of natural gas engines to complement its existing suite of diesel engines at its main manufacturing facility at Yulin City, Guangxi Zhuang Autonomous Region. The existing portfolio comprises natural gas engines for both on-road and off-road applications, all of which are compliant with China’s National V and National VI emission standards. For example, in 2018, Yuchai introduced four models of gas engines, YCS04N, YCK13N, YCK15N and YCA07N, compliant with National VI and Tier-4 emission standards for both on-road and off-road applications. The main applications of Yuchai’s natural gas engines are in the bus, truck and power generator sectors. See “Item 4. Information on the Company — Business Overview — Products and Product Development — Yuchai — Other products and services” for more information on Yuchai’s natural gas engines.

The development of a sustainable market for natural gas engines in China may be affected by many factors, some of which are beyond our control, including:

There can be no assurance, however, that a sustainable market for natural gas vehicles will develop in China or in other countries around the world or that our initiative to increase our market share in the natural gas engine market will be successful or profitable. For example, in 2016, our sales of natural gas engines continued to decline primarily due to increased demand for electric-powered vehicles and a reduction in oil prices. In 2017, the demand for gas engine trucks has seen a recovery due to certain provinces in northern China implementing new policies restricting the running of diesel trucks. Although demand for natural gas engines in 2018 slowed down due to a reduction of government incentives, demand for gas engine trucks in the fourth quarter of 2018 increased due to restrictions imposed on the operation of diesel engine trucks in certain harbors and terminals in the northern region of China.

The technological requirements to comply with National VI standards will require engine manufacturers to deploy significant resources on improving major engine components, systems and after treatment systems, in a relatively short period of time, which could lead to increased costs. Engine suppliers in the industry may face difficulty in implementing the emission upgrades in compliance with National VI emission standards for on-road vehicles.

Yuchai has committed substantial resources to continually improve the technology of its products and maintain the competitiveness of its products. For more information on Yuchai’s research and development efforts, see “Item 4. Information on the Company — Business Overview — Research and Development.”

Our research and development efforts may not be successful and our new products may not address the needs of our current and prospective customers or achieve market acceptance. Moreover, competitors may be in the process of developing technology that could be developed more quickly or eventually become more profitable than our products. If our investments in research and development do not yield new technologies and products that we can successfully market and sell, our business, financial condition and results of operations may be adversely affected.

15

Our financial condition, results of operations, business or prospects may be adversely affected to the extent we are unable to continue our sales growth.

In 2016, Yuchai recorded engine sales of 320,424 units. In 2017, engine sales increased to 367,097 units, a 14.6% increase compared with 2016. In 2018, engine sales increased to 375,731 units, a 2.4% increase compared with 2017. We cannot assure you that we will be able to maintain or increase engine sales in the future. For example, we may not be able to maintain or increase our engine sales or revenue commensurate with our increased levels of production capacity. Moreover, our future growth is dependent in large part on factors beyond our control, such as the continued growth and stability of the global and Chinese economies. See “Item 3. Key Information — Risk Factors — Risks relating to our company and our business — The diesel engine business in China is dependent in large part on the performance of the Chinese and the global economy. As a result, our financial condition, results of operations, business and prospects could be adversely affected by slowdowns in the Chinese and the global economy.” In addition, we cannot assure you that we will be able to properly manage any future growth, including:

Furthermore, we have acquired in the past, and may acquire in the future, equity interests in engine parts suppliers and logistics and marketing companies. If we are unable to effectively manage or assimilate these acquisitions, our financial condition, results of operations, business or prospects could be adversely affected.

We may be unable to obtain sufficient financing to fund our capital requirements which could limit our growth potential.

We believe that our cash from operations, together with any necessary borrowings, will provide sufficient financial resources to meet our projected capital and other expenditure requirements. If we have underestimated our capital requirements or overestimated our future cash flows, additional financing may be required. Financing may not be available to us on acceptable terms or at all. Our ability to obtain external financing is subject to various uncertainties, including our results of operations, financial condition and cash flow, economic, political and other conditions in China, the Chinese government’s policies relating to foreign currency borrowings and the condition of the Chinese and international capital markets. The Chinese government’s March 2019 Work Report recommended that to alleviate difficulties in obtaining financing and reduce borrowing cost of businesses, China’s central bank should make use of quantitative and pricing measures such as expanding credit delivery and lowering loan costs. While the People’s Bank of China (the “PBOC”) lowered bank reserve requirement ratios in the recent five years, China has maintained its one-year lending rate of 4.35% since October 2015. A shortage of liquidity in the banking system or any other factor that results in our inability to access capital may adversely affect our business, financial condition, results of operations and prospects.

We could be exposed to the impact of interest rates and foreign currency movements with respect to our future borrowings and business.

We may use borrowings from time to time to supplement our working capital requirements and to finance our business expansion and diversification plan. A portion of our borrowings may be structured on a floating rate basis and denominated in US dollar, Singapore dollar or Renminbi. In 2013, Yuchai issued the first tranche of RMB-denominated three year unsecured medium-term notes (“MTNs”) in China amounting to RMB 1.0 billion upon the receipt of approval from NAFMII, at an annual interest rate of 4.69%. The MTNs matured on May 30, 2016. In April and September 2015, Yuchai issued two tranches of ultra short-term bonds (“USTB”) amounting to a total of RMB 800 million at interest rates of 4.9% and 3.9% which matured on May 9, 2015 and June 13, 2016, respectively. See “Item 5. Operating and Financial Review and Prospects — Liquidity and Capital Resources.”

In 2015, there were significant reductions in interest rates for bank loans in China. For example, the interest rate varied between 5.6% and 4.35% in 2015 which affected our cost of funding and bill discounting, and our results of operations. In addition, following a period of unusually low interest rates, the U.S. Federal Reserve raised its benchmark interest rate in 2016 and 2017 and may further increase interest rates in the future. Any fluctuations in interest rates, or fluctuations in exchange rates between the Renminbi or Singapore dollar and US dollar, may increase our funding costs or the availability of funding. This could affect our financial condition, results of operations, business or prospects.

16

Our financial condition, results of operations, business or prospects could also be adversely affected by a devaluation of the Renminbi. The value of the Renminbi is subject to changes in Chinese government policies and to international economic and political developments. Since 1994, the conversion of Renminbi into foreign currencies, including US dollar, has been based on rates set by the PBOC. On July 21, 2005, China reformed its foreign exchange regime by moving into a managed floating exchange rate system based on market supply and demand with reference to a basket of currencies, such that the Renminbi was no longer pegged to the US dollar. On August 10, 2015, the PBOC introduced a change in the calculation of the Renminbi reference rate cutting its daily reference rate by 1.9 percent, in order to foster greater exchange rate flexibility. On December 1, 2015, the International Monetary Fund (the “IMF”) announced the inclusion of the Renminbi in the basket of currencies which make up the IMF’s Special Drawing Right (“SDR”). This was the first time in over 15 years that the list of currencies comprising the SDR has been altered recognizing China’s gradual integration into the world economy. On October 1, 2016, the Renminbi was officially included into the IMF’s SDR alongside the US dollar, the Japanese yen, Euro and the British pound. From December 31, 2014 to December 31, 2018, the Renminbi depreciated about 10.8% against the US dollar. From December 31, 2014 to December 31, 2018, the Singapore dollar depreciated about 2.9% against the US dollar. Since we may not be able to hedge effectively against Renminbi or Singapore dollar fluctuations, future movements in the exchange rate of the Renminbi, the Singapore dollar and other currencies could have an adverse effect on our business, financial condition and results of operations.

If China’s inflation increases or the prices of energy or raw materials increase, we may not be able to pass the resulting increased costs on to our customers and this may adversely affect our profitability or cause us to suffer operating losses.

Economic growth in China has, in the past, been accompanied by periods of high inflation. The Chinese government has implemented various policies from time to time to control inflation. For example, the Chinese government has periodically introduced measures in certain sectors to avoid overheating of the economy, including tighter bank lending policies, increases in bank interest rates, and measures to curb inflation, which has resulted in a decrease in the rate of inflation. According to the National Bureau of Statistics, the annual inflation rate for 2016, 2017 and 2018 was 2.0%, 1.6% and 2.1%, respectively, below the 3.0% target set by the Chinese government. On March 5, 2019, at the National People’s Congress in Beijing, Premier Li Keqiang in his annual policy report announced that the annual inflation rate target would be maintained at around 3.0% in 2019, the same inflation target as in 2016, 2017 and 2018. An increase in inflation could cause our costs for parts and components, labor costs, raw materials and other operating costs to increase, which would adversely affect our financial condition and results of operations. Recently, concerns have arisen over deflationary pressures in China as a result of weak domestic demand. A prolonged period of deflation may result in falling profits, closure of businesses, shrinking employment and incomes and increasing defaults on loans by companies and individuals, any of which could adversely affect our business, financial condition or results of operations.

We may be adversely affected by environmental regulations

We are subject to Chinese national and local environmental protection regulations which currently impose fees for the discharge of waste substances, require the payment of fines for pollution, and provide for the closure by the Chinese government of any facility that fails to comply with orders requiring us to cease or improve upon certain activities causing environmental damage. Due to the nature of our business, we produce certain amounts of waste water, gas, and solid waste materials during the course of our production.

We believe our environmental protection facilities and systems are adequate for us to comply with the existing national, provincial and local environmental protection regulations. However, Chinese national, provincial or local authorities may impose additional or more stringent regulations which would require additional expenditure on environmental matters or changes in our processes or systems. The National IV emission standards for diesel engines were implemented throughout China on July 1, 2013 and strict enforcement of the standards was implemented nationwide on January 1, 2015. In an effort to combat increasing air pollution, the National V emission standards for natural gas engines were implemented throughout China on January 1, 2013. In 2016, the Ministry of Industry and Information Technology and the Ministry of Environmental Protection (superseded by the Ministry of Ecology and Environment in 2018) announced that all light petrol vehicles, light diesel buses and heavy diesel vehicles used for the purposes of public transportation, environmental sanitation and postal services must comply with National V emission standards from January 1, 2017. All other heavy diesel vehicles and all light diesel vehicles nationwide are required to comply with the National V emission standards from July 1, 2017 and January 1, 2018, respectively. In December 2016, the Ministry of Environmental Protection announced the Limits and Measurement Methods for Emissions from Light-Duty Vehicles (National VI) that all light-duty gasoline and diesel-powered vehicles must comply with National VI(a) emission standards from July 1, 2020 and National VI(b) emission standards from July 1, 2023, subject to changes in the official implementation schedule.

On June 28, 2018, the Ministry of Ecology and Environment released the final rule for the National VI emission standards for heavy-duty vehicles. The National VI standards will be implemented in two phases. National VI(a) will take effect on July 1, 2019 for new gas-powered heavy-duty vehicles (HDVs), on July 1, 2020 for new urban HDVs, and July 1, 2021 for the remaining new HDVs. National VI(b) will take effect on January 1, 2021 for new gas-powered HDVs, then on July 1, 2023 for all new HDVs. When fully implemented, National VI will require all new HDVs sold in China to meet the standards.

Yuchai produces diesel engines compliant with National IV and National V emission standards and natural gas engines compliant with National V emission standards, and also has the ability to produce certain diesel and natural gas engines compliant with National VI emission standards and develop alternative fuels and environmentally friendly hybrid engines with improved fuel efficiency.

In October 2010 and October 2014, China officially implemented the Tier-2 and Tier-3 emission standards nationwide, respectively. Strict enforcement of the Tier-3 emission standards was implemented nationwide on December 1, 2016. Yuchai is able to produce diesel engines compliant with both Tier-2 and Tier-3 emission standards for use in off-road machinery. As distribution of Tier-2 compliant diesel engines is prohibited in China with effect from October 1, 2015, Yuchai has reduced production volumes of such engines but continues to produce such engines solely for export from China. In February 2019, the Ministry of Ecology and Environment announced that any off-road machinery that does not comply with Tier-4 emission standards is prohibited for production, import and selling in China from December 1, 2020, subject to changes in the official implementation schedule. It requires the engine manufacturers to expedite the research and development of engines compliant with Tier-4 emission standards.

While Yuchai produces diesel engines compliant with the current emission standards in both the off-road and on-road markets, Yuchai may be required to increase its research and development expenses in order to meet increasingly stringent emission standards, and there can be no assurance that Yuchai will be able to comply with applicable emission standards or that the introduction of these and other environmental regulations will not result in a material adverse effect on our business, financial condition and results of operations.

New National VI(a), VI(b) and Tier-4 emission standards for diesel engines manufactured in China

The manufacture of our engines is heavily regulated by governmental authorities, including the Ministry of Ecology and Environment. National VI(a), VI(b) and Tier-4 emission standards have adopted the latest internal combustion engine manufacturing technologies in China that Yuchai had to develop and build up anew. These new emission standards impose a whole series of stringent emission tests, not only in the manufacturing processes but also ongoing emission tests on the road after engine installation by a remote emission monitoring system or other monitoring systems.

In addition to regulatory requirements, many of our engines involve technically complex manufacturing processes and require a supply of highly specialized engine component parts. For some products and component parts, we may also rely on a single source of supply. The combination of these factors means that supply is never guaranteed. Like some of our competitors, we may face manufacturing issues from time to time. If we or our third party suppliers fail to comply fully with regulations, then there could be a product recall or other shutdown or disruption of our production activities. There can be no assurance that we will not experience supply interruptions for our products in the future.

U.S. and China Trade Dispute

In July 2018, the U.S. President, Donald Trump followed through on his threats by imposing tariffs on China’s exports to the U.S. for its alleged unfair trade practices. The U.S. has put tariffs on US$250 billion in Chinese goods so far and threatened tariffs on a further US$267 billion of goods, and China has retaliated with tariffs on US$110 billion on U.S. products and threatened qualitative measures that could affect U.S. businesses operating in China. Both the U.S. and China have been actively engaged in negotiations to resolve their trade disputes in the last few months and discussions are continuing. The outcome will not be known until both countries make an announcement. The impacts of the trade war and the progress of the negotiations are being closely followed by the global community as they could have far reaching effects on world trade and investments.

Our insurance coverage may not be adequate to cover risks related to our production and other operations.

The amount of our insurance coverage for our buildings and equipment is at cost which could be less than replacement value. The amount of our insurance coverage for our inventory is at book value which could be less than replacement value. In accordance with what we believe is customary practice among industrial equipment manufacturers in China, we insure high risk assets, such as property and equipment and inventory. The amount of our insurance coverage of our facilities and inventory is in line with Chinese market practice but may expose us to risks in the event of a major accident where our insurance recovery may be inadequate. We may not carry third party liability insurance to cover claims in respect of bodily injury, property or environmental damage arising from accidents on our property or relating to our operations, although we do carry such insurance for the period from June 2018 to June 2019. We do not carry business interruption insurance as such coverage is not customary in China. From time to time, we will review the adequacy of our insurance coverage. Nevertheless, losses incurred or payments required to be made by us which are not fully insured could have a material adverse effect on our financial condition.

We are dependent on information technology and our systems and infrastructure face certain risks, including cybersecurity risks and data leakage risks.

We are dependent on information technology systems and infrastructure. We cannot be certain that advances in criminal capabilities (including cyber-attacks or cyber intrusions over the internet, malware, computer viruses and the like), discovery of new vulnerabilities or attempts to exploit existing vulnerabilities in our or third-party systems, other data thefts, physical system or network break-ins or inappropriate access, or other developments will not compromise or breach the technology protecting our systems or the systems and networks of third parties that access and store sensitive information about us or our customers or suppliers. Cyber threats, such as phishing and trojans, could intrude into our or a third party’s network to steal data or to seek sensitive information about us or our customers or suppliers. Any intrusion into our or such third party’s network (to the extent attributed to us or perceived to be attributed to us) that results in any breach of security could cause damage to our reputation and adversely impact our business and financial results. A significant failure in security measures could have a material adverse effect on our business, reputation, results of operations and financial condition. Although we seek to implement measures to protect sensitive and confidential client data, there can be no assurance that we would be able to prevent breaches of security.

Risks relating to China

Substantially all of our assets are located in China, and substantially all of our revenue is derived from our operations in China. Accordingly, our financial condition, results of operations, business or prospects are subject, to a significant degree, to economic, political and legal developments in China. The economic system of China differs from the economies of most developed countries in many respects, including government investment, the level of development, control of capital investment, control of foreign exchange and allocation of resources.

Adverse changes in the economic policies of the Chinese government could have a material adverse effect on the overall economic growth of China, which could reduce the demand for our products and adversely affect our competitive position.

Economic reform in China has been ongoing since its shift from a planned economy to a market-oriented economy in the 1970s. The Chinese government has implemented economic reform measures emphasizing decentralization, management autonomy and development driven by market forces. Although these reforms have resulted in economic growth and social progress, their effects on various geographic regions and economic sectors across China have been uneven.

On November 15, 2013, after the closure of the Third Plenum of the 18^th Chinese Communist Party Congress, the Chinese government issued a comprehensive reform document detailing extensive new social and economic policies with the primary aim to restructure and rebalance the economy to a more sustainable model by focusing more on domestic consumption away from investment and export fueled growth. On March 5, 2016, at the National People’s Congress in Beijing, the growth target for China for the next five years from 2016 to 2020 was lowered to a range of between 6.5% to 7.0%. China’s GDP expanded at 6.6% in 2018. On March 5, 2019, at the National People’s Congress in Beijing, Premier Li Keqiang in his annual policy report set the target for GDP growth at a range between 6% to 6.5% for 2019.

The Chinese government remains committed to pursuing a range of reforms as laid out in its November 2013 reform document and the current leadership is expected to continue implementing new economic and social policies already announced and making further changes to existing policies as it continues to rebalance its economy. The Chinese government has implemented policies to control the rate of economic growth, manage inflation and otherwise regulate economic expansion. As periods of high inflation have accompanied economic growth, the Chinese government has, from time to time introduced industry-specific measures to avoid overheating of certain sectors, such as tightening bank lending policies, increasing bank interest rates, and seeking to curb real estate and stock market speculation and inflation. In recent times, in order to counteract slowing growth and a shortage of liquidity in its banking system, the Chinese government on a number of occasions reduced its one-year lending rate and lowered the reserve requirements to be held by banks in an effort to inject liquidity into the economy in response to deflationary and increasing slowdown pressures. See “Item 3. Key Information — Risk Factors — Risks Relating to Our Company and Our Business — The diesel engine business in China is dependent in large part on the performance of the Chinese and the global economy. As a result, our financial condition, results of operations, business and prospects could be adversely affected by slowdowns in the Chinese and the global economy.”

The Chinese government is undertaking a number of strategic initiatives that may directly or indirectly affect demand for our products. These include the “One Belt, One Road” initiative to develop a network of railways, highways and other forms of infrastructure in the Eurasian area, the proposed Regional Comprehensive Economic Partnership, which is a proposed free trade agreement, and the establishment of a new development bank to support infrastructure development in the Asia-Pacific region. Further, in view of the increased focus on domestic consumption and services, further initiatives and changes to existing economic and social policies are expected to be announced and implemented by the Chinese government. Although we believe that the economic initiatives, policies, measures and reforms adopted by the Chinese government will continue to have a positive long-term effect on economic development in China and that we will continue to benefit from these policies, measures and reforms, such government actions may, from time to time, be modified or reversed or have an adverse effect on the price of diesel and diesel-using products and the diesel engine market in general. Adverse changes in the Chinese laws, regulations or policies could have a material adverse effect on the overall economic growth of China and infrastructure investment in China. These developments could adversely affect our business, financial condition and results of operations.

Adverse economic developments in China or elsewhere in the Asian region could have a material adverse effect on our financial condition, results of operations, business or prospects.

The World Bank’s Global Economic Prospects issued in January 2019 projects global growth of 3% in 2018, 2.9% in 2019 and 2.8% from 2020 to 2021 as economic slack dissipates, monetary policy accommodation in advanced economies is removed, and global trade gradually slows. The World Bank estimates that growth in China will slow to a still robust 6.2% in 2019 amid domestic and external rebalancing, with resilient domestic demand helping to offset a deceleration of exports. For more information on the Chinese economy, see “Item 3. Key Information — Risks relating to our company and our business — The diesel engine business in China is dependent in large part on the performance of the Chinese and the global economy. As a result, our financial condition, results of operations, business and prospects could be adversely affected by slowdowns in the Chinese and the global economy.”

The Chinese legal system embodies uncertainties which could limit the legal protection available to foreign investors.

The Chinese legal system is a civil law system based on written statutes. Unlike common law systems, it is a system in which decided legal cases have little precedent value. In 1979, the Chinese government began to promulgate a comprehensive system of laws and regulations governing economic matters in general including, for example, with respect to corporate organization and governance, foreign investments, commerce, taxation and trade. Since China’s economic reform and opening-up in late 1970s, legislation has significantly enhanced the protection afforded to various forms of foreign investment in China. The laws, regulations and legal requirements relating to foreign investment are relatively recent and are still evolving, and their interpretation and enforcement involve uncertainties and may not be consistent or predictable as in other more developed jurisdictions which may limit the legal protection available to foreign investors.

Our operations in China are subject to PRC regulations governing PRC companies. These regulations contain provisions that are required to be included in the articles of association of PRC companies and are intended to regulate the internal affairs of these companies. The PRC Company Law and these regulations, in general, and the provisions for the protection of shareholders’ rights and access to information, in particular, are less developed than those applicable to companies incorporated in the United States, Hong Kong or other developed countries or regions. In addition, the interpretation of PRC laws may be subject to policy changes which reflect domestic political changes. On March 15, 2019, the PRC Foreign Investment Law (“FIL”) was adopted in the second session of the 13^th National People’s Congress. Upon its effectiveness on January 1, 2020, the existing Sino-Foreign Equity Joint Venture Law, the Wholly Foreign Owned Enterprise Law and the Sino-Foreign Cooperative Joint Venture Law will be repealed and FIL will become the sole law regulating foreign investment enterprises (“FIEs”). FIL establishes uniform principals for foreign investment, which in effect will mean that foreign investors in China (except for those on an FIL “negative list”) will enjoy the same treatment as domestic investors. FIL grants FIEs a five-year transition period during which an FIE may retain its current organizational form while rules are being promulgated by the State Council. The promulgation of new laws, changes to existing laws and the pre-emption of local regulations by national laws may have an adverse effect on our prospects, financial condition and results of operations.

We may not freely convert Renminbi into foreign currency, which could limit our ability to obtain sufficient foreign currency to satisfy our foreign currency requirements or to pay dividends to shareholders.

Substantially all of our revenues and operating expenses are generated by our Chinese operating subsidiary, Yuchai, and are denominated in Renminbi, while a portion of our indebtedness is, or in the future may be, denominated in US dollar and other foreign currencies. The Renminbi is currently freely convertible under the “current account,” which includes dividends, trade and service-related foreign exchange transactions, but not under the “capital account,” which includes, among other things, foreign direct investment, overseas borrowings by Chinese entities and proceeds of overseas public offering by Chinese entities. Some of the conversions between Renminbi and foreign currency under the capital account are subject to the prior approval of the State Administration for Foreign Exchange, or SAFE. On December 11, 2015, China announced the convertibility of Renminbi on its capital account within a prescribed limit of US$10 million for the free-trade zones of Tianjin, Guangdong and Fujian, an initial step towards the opening of its capital account.

Yuchai, as a foreign invested enterprise, may purchase foreign currency without the approval of SAFE for settlement of “current account transactions”, including payment of dividends, by providing commercial documents evidencing these transactions. Our Chinese operating subsidiary may also retain foreign exchange in its current account to satisfy foreign currency liabilities or to pay dividends. However, the relevant Chinese government authorities may limit or eliminate our Chinese operating subsidiary’s ability to purchase and retain foreign currencies in the future. Our Chinese operating subsidiary, therefore, may not be able to obtain sufficient foreign currency to satisfy its foreign currency requirements to pay dividends to us for our use in making any future dividend payments or to satisfy other foreign currency payment requirements. Foreign currency transactions under the capital account and foreign debt account continue to be subject to limitations and require registrations with and reviews from the designated foreign exchange banks and SAFE. This could affect our Chinese operating subsidiary’s ability to obtain foreign currency through debt or equity financing, including by means of loans or capital contributions from us. The General Affairs Department of SAFE promulgated circulars in August 2008 and July 2011, pursuant to which, Renminbi converted from capital contribution in foreign currency to a domestic enterprise in China can only be used for the activities that are within the approved business scope of such enterprise and cannot be used for China domestic equity investment, acquisition, giving entrusted loans or repayment of intercompany loans, with limited exceptions. On March 30, 2015, SAFE issued a notice to take effect from June 1, 2015 loosening the explicit prohibition against the use of Renminbi converted from capital contribution in foreign currency for domestic equity investment as set out in its circulars of August 2008 and July 2011. On June 9, 2016, SAFE issued a notice which became effective on the same day, further allowing the use of Renminbi converted from capital contribution in foreign currency to be used for providing loans to affiliated enterprises of foreign invested enterprises. We can give no assurance as to the effect of changes in Renminbi and foreign currency regulations on our business, financial condition and results of operations.

20

Outbreaks of communicable diseases in various parts of China and other countries may materially and adversely affect our business, financial condition and results of operations.

We face risks related to health epidemics or outbreaks of communicable diseases. For example, in 2003, several countries, including China, experienced an outbreak of a highly contagious form of atypical pneumonia known as severe acute respiratory syndrome (“SARS”), which severely restricted the level of economic activity in affected areas and had an adverse impact on the sale of engines, particularly during the second and third quarters in 2003. In 2009, an outbreak of H1N1 flu first occurred in Mexico and quickly spread to other countries, including China. In addition, an infectious strain of influenza known as the H5N1 Avian flu has been reported from time to time in China, Hong Kong, Vietnam, and other parts of Asia. More recently, a new strain of Avian flu (H7N9) was reported in China and a new virus known as the novel coronavirus, NCoV, was reported in the Middle East and other parts of the world. Beginning in 2014, the largest Ebola virus outbreak in history affected numerous countries in West Africa and led to various reported cases of Ebola around the world. In April 2015 through early 2017, outbreaks of Zika fever caused by the Zika virus were recorded in countries around the world.

The outbreak of such communicable diseases could result in a widespread health crisis that could adversely affect general commercial activity and the economies and financial markets of many countries. Since most of our operations and customers and suppliers are based in Asia, an outbreak of these or any other communicable diseases in Asia or elsewhere, or the perception that such an outbreak could occur, and the measures taken by the governments of countries affected could adversely affect our business, financial condition or results of operations.

Our auditor engages its China-based affiliate to audit our China entities. Because registered public accounting firms in China, including our auditor’s China-based affiliate, are not permitted under Chinese law to be inspected by the U.S. Public Company Accounting Oversight Board, investors may be deprived of the benefits of such inspection.

Our independent registered public accounting firm that issues the audit reports included in our annual reports filed with the SEC, as an auditor of companies whose shares are publicly traded in the United States, is registered with the U.S. Public Company Accounting Oversight Board (the “PCAOB”). As a PCAOB registered firm, our auditor is required by the laws of the United States to undergo regular inspections by the PCAOB to assess its compliance with relevant U.S. laws and professional standards. Our auditor engages its China-based affiliate to audit our China entities and China is a jurisdiction where the PCAOB is currently unable to conduct inspections without the approval of the Chinese authorities. In May 2013, the PCAOB announced that it had entered into a Memorandum of Understanding on Enforcement Cooperation with the China Securities Regulatory Commission (the “CSRC”) and the China Ministry of Finance (the “China MoF”) to establish a cooperative framework for the production and exchange of audit documents relevant to investigations undertaken by the PCAOB, the CSRC or the China MoF in the United States and China. However, the parties have not reached a definitive agreement to permit joint inspections in China of audit firms that are registered with the PCAOB and audit Chinese companies that trade on U.S. stock exchanges. On December 7, 2018, the SEC and the PCAOB issued a joint statement highlighting continued challenges faced by the U.S. regulators in their oversight of financial statement audits of U.S.-listed companies with significant operations in China.

The inability of the PCAOB to conduct inspections of the China-based affiliate of our independent registered public accounting firm makes it more difficult to evaluate the effectiveness of such affiliate’s audit procedures or quality control procedures. As a result, investors may be deprived of the benefits of PCAOB inspections, and investors and potential investors in our stock may lose confidence in our audit procedures, reported financial information and the quality of our financial statements, which may adversely affect the market price of our shares.

21

If additional remedial measures are imposed on the Chinese affiliates of certain global accounting firms, including the “big four” accounting firms pursuant to administrative proceedings brought by the SEC against them, we could be unable to timely file future financial statements in compliance with the requirements of the Securities Exchange Act of 1934, as amended (the “Exchange Act”).

Starting in 2011 the Chinese affiliates of certain global accounting firms, including our independent registered public accounting firm, were affected by a conflict between U.S. and Chinese laws. Specifically, for certain U.S.-listed companies operating and audited in mainland China, the SEC and the PCAOB sought to obtain from the Chinese firms access to their audit work papers and related documents. The firms were, however, advised and directed that under China law they could not respond directly to the US regulators on those requests, and that requests by foreign regulators for access to such papers in China had to be channeled through the CSRC.

In late 2012, this impasse led the SEC to commence administrative proceedings under Rule 102(e) of its Rules of Practice and also under the Sarbanes-Oxley Act against the Chinese accounting firms, (including our independent registered public accounting firm). A first instance trial of the proceedings in July 2013 in the SEC’s internal administrative court resulted in an adverse judgment against the firms. The administrative law judge proposed penalties on the firms including a temporary suspension of their right to practice before the SEC, although that proposed penalty was subject to the pending review of the SEC Commissioner. On February 6, 2015, prior to the SEC Commissioner’s scheduled review, the firms reached a settlement with the SEC. Under the settlement, the SEC agreed that its future requests for the production of documents would normally be made to the CSRC. The firms would receive matching requests under Section 106 of the Sarbanes-Oxley Act, and are required to abide by a detailed set of procedures with respect to such requests, which in substance required them to facilitate production via the CSRC. If they fail to meet the specified criteria, the SEC retains the authority to impose a variety of additional remedial measures on the firms depending on the nature of the failure. Remedies for any future noncompliance could include, as appropriate, an automatic six-month bar on a single firm’s performance of certain audit work, commencement of a new proceeding against the firm, or in extreme cases, the resumption of the current proceeding against all four “big four” accounting firms.

Risks relating to our investment in HLGE

The HLGE group operates Copthorne Hotel Cameron Highlands (“CHCH”), a hotel in Cameron Highlands, Malaysia. As of February 28, 2019, we had a 48.9% shareholding interest in HLGE, a company listed on the Main Board of the Singapore Exchange Securities Trading Limited (the “Singapore Exchange”). See “Item 5. Operating and Financial Review and Prospects — Business Expansion and Diversification Plan” for further information on our investment in HLGE. Set forth below are risks related to our equity interest in HLGE.

The HLGE group’s hotel ownership and management business may be adversely affected by risks inherent in the hotel industry.

The HLGE group’s financial performance is dependent on the performance of the hotel it operates. The HLGE group’s hotel ownership and management business are exposed to risks which are inherent in and/or common to the hotel industry and which may adversely affect the HLGE group’s financial performance, including the following:

22

The above factors may materially affect the performance of CHCH and the profitability and financial condition of the HLGE group. There can be no assurance that we will not suffer any losses arising from our investment in HLGE.

The hospitality business is a regulated business.

The operation of hotels in Malaysia is subject to various laws and regulations. The withdrawal, suspension or non-renewal of any of the hotels’ licenses, or the imposition of any penalties, as a result of any infringement or non-compliance with any requirement, will have an adverse impact on the business and results of operations of CHCH. Further, any changes in such laws and regulations may also have an impact on the businesses at the hotels and result in higher costs of compliance. In addition, any failure to comply with these laws and regulations could result in the imposition of fines or other penalties by the relevant authorities. This could have an adverse impact on the revenues and profits of HLGE group or otherwise adversely affect the operations of CHCH.

ITEM 4. INFORMATION ON THE COMPANY

History and Development

The Company

China Yuchai International Limited is a Bermuda holding company established on April 29, 1993 to own a controlling interest in Yuchai. We currently own, through six of our wholly-owned subsidiaries, 76.4% of the outstanding shares of Yuchai. We operate as an exempted company limited by shares under The Companies Act 1981 of Bermuda. Our registered office is located at 2 Clarendon House, Church Street, Hamilton HM11, Bermuda. On March 7, 2008, we registered a branch office of the Company in Singapore, located at 16 Raffles Quay #26-00, Hong Leong Building, Singapore 048581. Our principal operating office is located at 16 Raffles Quay #39-01A, Hong Leong Building, Singapore 048581. Our telephone number is (+65) 6220-8411. Our transfer agent and registrar in the United States is Computershare Inc., located at 480 Washington Blvd., 26^th Floor Jersey City, NJ 07310.

Until August 2002, we were controlled by Diesel Machinery, a company that was 53.0% owned by Hong Leong Asia, through its wholly-owned subsidiary, Hong Leong China. Hong Leong China owns HL Technology which held shares in us through Diesel Machinery. Diesel Machinery was also 47.0% owned by China Everbright Holdings Company Limited, or China Everbright Holdings, through its wholly-owned subsidiary, Coomber. Hong Leong Asia, a company listed on the Singapore Exchange, is part of the Hong Leong Investment group, which was founded in 1941 by the Kwek family of Singapore and remains one of the largest privately-controlled business groups in Southeast Asia. China Everbright Holdings is a state-owned enterprise of China. In 2002, China Everbright Holdings and Coomber gave notice to Diesel Machinery and the other shareholders of Diesel Machinery to effect a liquidation of Diesel Machinery. As a result of the liquidation, Hong Leong Asia acquired the special share through HL Technology which entitles Hong Leong Asia to elect a majority of our directors and also to veto any resolution of our shareholders. China Everbright Holdings sold its shareholding in Coomber, which held shares of our Common Stock, in October 2002 to Goldman Industrial Limited, or Goldman, and China Everbright Holdings is no longer a shareholder of our company. Goldman was a subsidiary of Zhong Lin Development Company Limited, or Zhong Lin, an investment vehicle of the city government of Yulin in Guangxi, China until September 29, 2006 when Zhong Lin sold its shareholding in Goldman to the State Holding Company.

We provide certain management, financial planning, internal audit services, internal control testing, IFRS training, business enhancement consulting and other services to Yuchai and we continue to have a team working full-time at Yuchai’s principal manufacturing facilities in Yulin city. In addition, the President, Chief Financial Officer and a manager proficient in Section 404 of Sarbanes—Oxley Act of 2002, or SOX, travel frequently, usually monthly for as much as up to two weeks at a time, to Yuchai to actively participate in Yuchai’s operations and decision-making process.

Our main operating asset has historically been, and continues to be, our ownership interest in Yuchai, and our primary source of cash flow has historically been our share of the dividends, if any, paid by Yuchai and investment income thereon. However, on February 7, 2005, the Board of Directors of the Company announced its approval of the implementation of a business expansion and diversification plan by the Company. Following such announcement, we have looked for new business opportunities to seek to reduce our financial dependence on Yuchai:

HLGE and TCL are each listed on the Main Board of the Singapore Exchange.

We have eight wholly-owned subsidiaries which directly hold investments in Yuchai, HLGE and TCL, as described below:

24

On March 27, 2019, W Capital Markets Pte. Ltd., for and on behalf of Prime Trade Enterprises Limited, an investment holding company ultimately owned and controlled by certain members of the Thakral family, announced a voluntary conditional cash partial offer to acquire approximately 20% of the total issued shares of TCL. We are currently considering our options in relation to our investment in the TCL group including disposing of our entire shareholding in TCL.

For more details on our investments in HLGE and TCL, see “Item 5. Operating and Financial Review and Prospects — Business Expansion and Diversification Plan.”

Yuchai

Yuchai engages in the manufacture, assembly and sale of a wide variety of light-, medium- and heavy-duty engines for trucks, buses, passenger vehicles, construction equipment, and marine and agriculture applications in China. Yuchai also produces engines for diesel power generators. The engines produced by Yuchai range from diesel to natural gas and hybrid engines. Through its regional sales offices and authorized customer service centers, Yuchai distributes its engines directly to auto original equipment manufacturers (“OEMs”) and retailers and provides maintenance and retrofitting services throughout China.

Yuchai was founded in 1951 and became a state-owned enterprise in 1959. Prior to 1984, Yuchai was a small producer of low-power diesel engines for agricultural machinery. In 1984, Yuchai introduced the earliest model of its YC6J diesel engine for medium-duty trucks. In July 1992, in order to raise funds for further expansion, Yuchai became the first state-owned enterprise in the Guangxi Zhuang Autonomous Region to be restructured into a joint stock company. As a result of this restructuring, Yuchai was incorporated as a joint stock company in July 1992 and succeeded the machinery business of Yulin Diesel. All of Yulin Diesel’s businesses, other than its machinery business, as well as certain social service related operations, assets, liabilities and employees (for example, cafeterias, cleaning and security services, a hotel and a department store), were transferred to the State Holding Company. The State Holding Company also became the majority shareholder of Yuchai through its ownership stake of approximately 104 million shares of Yuchai, or State Shares. The State Holding Company is owned by the Yulin City government. In connection with its incorporation, Yuchai also issued seven million shares to various Chinese institutional investors, or Legal Person Shares.

In May 1993, in order to finance further expansion, Yuchai sold shares to the Company, or Foreign Shares, and became a Sino-foreign joint stock company.

Our initial shareholders, consisting of HL Technology, Sun Yuan Overseas (BVI) Ltd., or Sun Yuan BVI, the Cathay Investment Fund, Limited, or Cathay, GS Capital Partners L.P., or GSCP, and Coomber, then a wholly-owned subsidiary of China Everbright Holdings and, thus, controlled by China Everbright International Limited, or China Everbright International, made their initial investments in Yuchai in May 1993, when their respective wholly-owned subsidiaries purchased for cash in the aggregate 200 million newly-issued shares of Yuchai (51.3% of the then-outstanding Yuchai Shares). These shareholders exchanged with the Company their shareholdings in their wholly-owned subsidiaries, six companies which held Foreign Shares of Yuchai, for 20 million shares of our Common Stock (after giving effect to a 10-for-1 stock split in July 1994, or the Stock Split). In connection therewith, Yuchai became a Sino-foreign joint stock company and became subject to the laws and regulations relating to joint stock limited liability companies and Sino-foreign joint venture companies in China. Foreign Shares may be held by and transferred to non-Chinese legal and natural persons, subject to the approval of the Ministry of Commerce, the successor entity to the Ministry of Foreign Trade and Economic Cooperation of China, or MOFTEC. Foreign Shares are entitled to the same economic rights as State Shares and Legal Person Shares. State Shares are shares purchased with state assets by government departments or organizations authorized to represent state investment. Legal Person Shares are shares purchased by Chinese legal persons or institutions or social groups with legal person status and with assets authorized by the state for use in business.

In November 1994, we purchased from an affiliate of China Everbright Holdings 78,015,500 Foreign Shares of Yuchai in exchange for the issuance of 7,801,550 shares of our Common Stock (after giving effect to the Stock Split), or the China Everbright Holdings Purchase. The 78,015,500 Foreign Shares of Yuchai held by Earnest Assets Limited, a subsidiary of China Everbright Holdings and China Everbright International before its sale to us had been originally issued as Legal Person Shares and State Shares and were converted to Foreign Shares, pursuant to approvals granted by MOFTEC. As a result, the Company became the owner of each of these six companies: Hong Leong Technology Systems (BVI) Ltd., Tsang & Ong Nominees (BVI) Ltd., Cathay Diesel Holdings Ltd., Goldman Sachs Guangxi Holdings (BVI) Ltd., Youngstar Holdings Limited and Earnest Assets Limited.

In December 1994, we sold 7,538,450 shares of Common Stock in our initial public offering and used substantially all of the proceeds to finance our six wholly-owned subsidiaries’ purchase of 83,404,650 additional Foreign Shares in Yuchai.

25

In connection with our purchase, through our six wholly-owned subsidiaries, of additional Foreign Shares in Yuchai with proceeds of our initial public offering, Yuchai offered additional shares pro rata to its other existing shareholders (30 shares for each 100 shares owned) in accordance with such shareholders’ pre-emptive rights, and each of our subsidiaries was able to acquire these additional Foreign Shares in Yuchai. Such pro rata offering (including the offering to the Company) is referred to herein as the “Yuchai Offering.” Certain Legal Person shareholders subscribed for additional shares in the Yuchai Offering. The State Holding Company informed Yuchai at the time that it would not subscribe for any of its portion of Yuchai Shares (31,345,094 shares) in the Yuchai Offering. In order to obtain MOFTEC’s approval of the Yuchai Offering, the State Holding Company was given the right by Yuchai’s Board of Directors to subscribe for approximately 31 million shares of Yuchai at a price of RMB 6.29 per share at any time prior to December 1998. This was because provisional regulations of the State Administration Bureau of State Property, or SABSP, and the State Committee of Economic System Reform, or SCESR, published in November 1994, imposed on any holder of state-owned shares certain obligations to protect its interest in any share offering. Under such regulations, the State Holding Company could have been required to subscribe for Yuchai Shares in the Yuchai Offering. Yuchai’s shareholders subsequently agreed to extend the duration of such subscription right to March 31, 2002 (the exercise of which would have reduced our ownership of Yuchai from 76.4% to 71.7%). The State Holding Company informed the shareholders of Yuchai that it had determined not to subscribe for additional Yuchai Shares and this determination was noted by the Yuchai Board of Directors on November 1, 2002. However, given the November 1994 provisional regulations of the SABSP and the SCESR, the SABSP, the SCESR and/or the Ministry of Commerce may take action against the State Holding Company, and there can be no assurance that any such action would not, directly or indirectly, have a material adverse effect on Yuchai or the Company.

Reorganization Agreement

On April 7, 2005, we entered into the Reorganization Agreement with Yuchai and Coomber, which is intended to be in furtherance of the implementation of the restructuring contemplated in the agreement dated July 19, 2003 between the Company and Yuchai with respect to the Company’s investment in Yuchai (the “July 2003 Agreement”), as amended and incorporated into the Cooperation Agreement on June 30, 2007. The terms of the Reorganization Agreement have also been acknowledged and agreed to by the State Holding Company. The Reorganization Agreement provides for the implementation of corporate governance guidelines approved by the directors and shareholders of Yuchai in November 2002 and outlines steps for the adoption of corporate governance practices at Yuchai conforming to international custom and practice. Pursuant to the Reorganization Agreement, Yuchai also acknowledged and affirmed our continued rights as majority shareholder to direct the management and policies of Yuchai through Yuchai’s Board of Directors.

Subsequent to the execution of the Reorganization Agreement, a number of steps have been taken by the parties thereto towards its implementation. For example, Yuchai’s directors and shareholders have confirmed that the amendments to Yuchai’s Articles of Association and corporate governance guidelines required to be adopted by Yuchai pursuant to the Reorganization Agreement have been ratified and implemented, and that steps are being taken to have such amendments and guidelines approved by the relevant Chinese authorities. The amended Articles of Association was approved by the Guangxi Department of Commerce on December 2, 2009.

Cooperation Agreement

The Reorganization Agreement was scheduled to terminate on June 30, 2007. On June 30, 2007, we entered into the Cooperation Agreement with Yuchai, Coomber and the State Holding Company. The Cooperation Agreement amends certain terms of the Reorganization Agreement, as amended, among CYI, Yuchai and Coomber, and as so amended, incorporates the terms of the Reorganization Agreement.

Pursuant to the amendments to the Reorganization Agreement, the Company agreed that the restructuring and spin-off of Yuchai would not be effected, and, recognizing the understandings that have been reached between the Company and the State Holding Company to jointly undertake efforts to expand the business of Yuchai, the Company would not seek to recover the anti-dilution fee of US$20 million from Yuchai.

The Cooperation Agreement provides that the parties will explore new business opportunities and ventures for the growth and expansion of Yuchai’s existing businesses. Although the parties to the Cooperation Agreement expect to work towards its implementation as expeditiously as possible, no assurance can be given as to when the transactions contemplated therein will be consummated.

Various amendments to Yuchai’s Articles of Association had been ratified and adopted by Yuchai in 2007 and were approved by the Guangxi Department of Commerce on December 2, 2009.

Business Overview

Emission Standards

The National IV emission standards for diesel engines were implemented throughout China on July 1, 2013 and strict enforcement of the standards nationwide commenced on January 1, 2015. In an effort to combat increasing air pollution, the National V emission standards for natural gas engines were implemented throughout China on January 1, 2013. In addition, the Chinese government mandated that all new registrations in Beijing of diesel engine vehicles for use in public transit and light-duty gasoline powered engine vehicles must comply with the National V emission standards with effect from February 1, 2013 and March 1, 2013, respectively. In 2016, the Ministry of Industry and Information Technology and the Ministry of Environmental Protection (superseded by the Ministry of Ecology and Environment in 2018) announced that all light petrol vehicles, light diesel buses, and heavy diesel vehicles used for the purposes of public transportation, environmental sanitation and postal services must comply with National V emission standards from January 1, 2017. All other heavy diesel vehicles and all light diesel vehicles nationwide are required to comply with the National V emission standards from July 1, 2017 and January 1, 2018, respectively. In December 2016, the Ministry of Environmental Protection announced the Limits and Measurement Methods for Emissions from Light-Duty Vehicles (National VI) that all light-duty gasoline- and diesel-powered vehicles must comply with National VI(a) emission standards with effect from July 1, 2020 and all diesel-powered vehicles must comply with National VI(b) emission standards from July 1, 2023. In February 2019, the Ministry of Ecology and Environment announced that any off-road machinery that does not comply with Tier-4 emission standards is prohibited for production, import and selling in China from December 1, 2020, subject to changes in the official implementation schedule.

Yuchai produces diesel engines compliant with National V and National VI emission standards and natural gas engines compliant with National V and National VI emission standards as well as develop alternative fuels and environmentally friendly hybrid engines with improved fuel efficiency. In October 2010 and October 2014, China officially implemented the Tier-2 and Tier-3 emission standards nationwide, respectively. Strict enforcement of the Tier-3 emission standards was implemented nationwide on December 1, 2016. The Tier-4 emission standards were implemented in Beijing and Shenzhen on January 1, 2015 and October 1, 2015, respectively. Yuchai is able to produce diesel engines compliant with both Tier-2 and Tier-3 emission standards for use in off-road machinery. As distribution of Tier-2 compliant diesel engines is prohibited in China with effect from October 1, 2015, Yuchai has reduced production of such engines but continues to produce such engines solely for export from China. In February 2019, the Ministry of Ecology and Environment announced that any off-road machinery that does not comply with Tier-4 emission standards is prohibited for production, import and selling in China from December 1, 2020, subject to changes in the official implementation schedule. It requires the engine manufacturers to expedite the research and development of engines compliant with Tier-4 emission standards.

Products and Product Development — Yuchai

Yuchai manufactures diesel and natural gas engines for light-, medium- and heavy-duty trucks, buses and passenger vehicles, marine and industrial applications and generator sets. Yuchai also manufactures diesel engines for construction and agriculture applications and is a supplier of after-market parts and services.

In 2018, Yuchai revised its classification system for light-, medium- and heavy-duty engines. Light-duty engines have engine capacity of 3.8 liters and less; medium-duty engines have engine capacity of between 3.8 liters and 7.0 liters; and heavy-duty engines have engine capacity of more than 7.0 liters. In addition to engine capacity, the new classification system takes into account the commercial application of the engines by original equipment manufacturers. For example, certain 4-cylinder engines that were previously classified as light-duty engines have been reclassified as medium-duty engines to the extent that they have application in the light- and medium-duty segments. For more information, see “Certain Definitions and Supplemental Information.”

Yuchai intends to improve its competitiveness across all current engine platforms, including light-, medium- and heavy-duty engines. Yuchai is focusing on higher emission standard engines, which are relatively higher margin products compared to traditional mechanical diesel engines. We have developed and commenced production of these high emission standard engines prior to the implementation dates for such standards in China. In 2018, Yuchai established a new subsidiary, Guangxi Yuchai Exhaust Technology Co., Ltd. to design, produce and sell exhaust emission control systems to meet National VI standards.

Yuchai is also expanding its production and research and development capabilities in natural gas engines in order to meet the growing demand in the natural gas engine market in China and provide a full range of natural gas engines to complement all of its current diesel engine models. Yuchai is also extending its high horse power marine diesel and power generator engines to cover engines from 16 liters up to 107 liters.

The following table sets forth the breakdown of Yuchai’s production at the Yulin facility by major product category for the years ended December 31, 2016, 2017 and 2018:

Note:

Procurement

Yuchai manufactures engine blocks, cylinder heads, crankshaft, camshaft and certain other key parts. Third party suppliers provide the remaining engine parts. The production process involves the complete assembly and testing of the finished product.

Engine Block

Yuchai cast and molded more than 359,000 units of engine blocks in 2018 representing a large portion of its engine blocks used in production.

Raw Materials

Yuchai purchases raw materials, principally scrap steel and cast iron, from domestic suppliers. An increase in the prices of these raw materials would generally increase our costs of production. We have experienced volatility in the prices of raw materials in the past. See also “Item 3. Key Information — Risk Factors — Risks relating to our company and our business — If China’s inflation increases or the prices of energy or raw materials increase, we may not be able to pass the resulting increased costs on to our customers and this may adversely affect our profitability or cause us to suffer operating losses.”

Imports

Certain engine components are imported from international suppliers, such as the electronic combustion system and its software, and the exhaust after-treatment components. A majority of the remaining parts are purchased from domestic suppliers. Yuchai has progressively reduced its reliance on imported parts and components since 2006. Yuchai has a policy of practicing sound procurement policy by requiring the same product procurement from at least two distinct sources. The same practice applies to all other externally procured engine parts. Yuchai is continually seeking to improve its procurement strategy by seeking new suppliers with competitive prices and quality.

36

Quality Assurance, Control and Safety

All raw materials, external supplied parts and components are checked for conformity with the required quality and specifications. Each stage of the production process is monitored by a quality control procedure and the final product undergoes standard conformity and specification testing using an automated testing laboratory. To promote the safety of its workers, Yuchai has established a safety department to supervise the proper use of equipment to prevent fire and explosions and promote safe practices and procedures in the workplace.

Manufacturing Capacity Expansion

Yuchai believes that the current production capacity of all engine lines will meet the expected demand. Yuchai is continuously assessing the market demand and devising production strategies to secure and meet these market opportunities.

Research and Development

Yuchai has committed substantial resources to continually improve the technology of its products and maintain the competitiveness of its products. Yuchai’s internal development effort focuses primarily on designing new products, improving manufacturing processes and adapting foreign technology to the Chinese market. Yuchai has committed to continually improve the technology of its products by acquiring advanced technology from Chinese research institutes, foreign engine design consulting firms and foreign diesel engine and engine parts manufacturers.

In 2016, Yuchai’s research and development efforts were mainly related to the development of new and existing engine products compliant with National V and National VI emission standards for on-road applications, engine products compliant with Tier-4 emission standards for off-road applications and its first plug-in gas hybrid engine compliant with National V emission standards in China for the truck segment. In 2017, Yuchai’s research and development efforts were mainly related to the upgrading of existing on-road and off-road products compliant with National V and Tier-3 emission standards and the development of new engine products compliant with forthcoming National VI and Tier-4 emission standards. In 2017, Yuchai also commenced the development of new energy vehicle power systems, including a third-generation hybrid engine and electric vehicle power systems. In 2018, research and development efforts were mainly for research and development of new engines compliant with the more stringent National VI and Tier-4 emission standards that are to be implemented over the next few years.

As a result of its research and development efforts, Yuchai has a large patent portfolio with over two thousand patents registered in China as of December 31, 2018. The types of patents that Yuchai has registered are invention patents, utility model patents and design patents. The term of patent protection is ten or 20 years from the filing date depending on the type of patent registered.

Future Products

Yuchai believes that its long-term business prospects will largely depend upon its ability to develop and introduce new or improved products with higher quality and competitive pricing. Future products may utilize different technologies and may require knowledge of markets that Yuchai does not currently possess.

Yuchai intends to continue to work with foreign engine design consulting firms and foreign engine manufacturers for technological assistance in improving its products and developing new products, and expects such cooperation to continue. The introduction of new engine products will also require significant capital expenditures, such as purchases of foreign manufacturing equipment and technologies. See “Item 3. Key Information — Risk Factors — Risks relating to our company and our business — Competition in China from other diesel engine manufacturers may adversely affect our financial condition, results of operations, business or prospects.”

Sales, Marketing and Services

Sales and Marketing

Yuchai distributes most of its engines directly to auto plants and agents from its primary manufacturing facilities in Yulin City. In addition, Yuchai operates a number of regional offices in major geographic regions in China. With a sales force of approximately 777 persons nationwide in China, Yuchai provides a comprehensive range of services to its customers, including dispatching engineers to provide on-site assistance to major customers in the resolution of technical problems.

Yuchai promotes its products primarily through television commercials, outdoor sign boards, advertisements in newspapers and industry journals. Since 1993, Yuchai has been sponsoring an annual program for its customer service stations with information brochures and customer suggestion cards for the improvement of Yuchai’s service. These customer service stations form Yuchai’s service and maintenance network. In relation to those engines which are under warranty cover, these customer service stations perform the routine maintenance checks and repairs on end-users’ diesel engines free of charge to the customers, and the corresponding costs are borne by Yuchai. In relation to those engines when the warranty expires, these customer service stations can continue to serve Yuchai clients at their own choice and costs.

Yuchai believes that its promotional efforts are unique for an automotive component company in China and lead to greater brand name recognition among end-users. Yuchai further believes that it leads its competitors in providing high quality after-sales services by its 2,620 authorized customer service stations in China. The customer service stations are independently owned and are able to provide emergency services to its end-users within a 40-km radius in the central, eastern and southern parts of China.

Yuchai has continued to focus its sales efforts on retailers and end-users of diesel engines. Yuchai seeks to encourage end-users of gasoline engine trucks to replace their gasoline engines with Yuchai diesel engines by advertising the advantages of diesel engines. With the advent of a natural gas refueling network across the nation, customers have the additional option of using Yuchai’s natural gas engines. Such sales of replacement engines are generally made through customer service centers at a retail price which is higher than the sales price to truck manufacturers.

Yuchai believes that proximity to its factories in Yulin City is an important factor in the geographical make-up of its customers. Due in part to transportation and shipping costs, a substantial majority of Yuchai’s engines are sold to customers in southern and central eastern China. Customers’ geographical make-up is segmented by Guangxi, Henan, Sichuan, Hubei, Fujian, East and North East China.

Yuchai’s sales are concentrated among the Dongfeng Group, one of the largest state-owned automobile companies in China, and other major diesel truck manufacturers controlled by or affiliated with the Dongfeng Group. In 2017, sales to the Dongfeng Group accounted for approximately 29.9% of Yuchai’s total revenue, of which our two largest customers, Dongfeng Liuzhou Motor Co., Ltd. and Dong Feng Special Vehicle Chassis National Agent (a Dong Feng Commercial Vehicle Co, Ltd. company), accounted for 15.1%. In 2018, sales to the Dongfeng Group accounted for approximately 27.5% of Yuchai’s total revenue, of which our two largest customers, Dongfeng Liuzhou Motor Co., Ltd. and Dongfeng Automobile Co., Ltd, accounted for 13.5%. The Dongfeng Group is also a major competitor of Yuchai. Our sales to our top five customers including sales to the Dongfeng Group accounted for 37.5% of our total revenue in 2018. See “Item 4. Information on the Company — Business Overview — Competition.”

Customers’ orders with Yuchai can be cancelled either by Yuchai or its customers prior to delivery in accordance with the sales contracts. As part of Yuchai’s credit procedures to control and manage its trade receivables, Yuchai may hold shipments for delivery if customers’ credit positions are not satisfactory or if customers have not made payments for earlier deliveries. There can be no assurance that such cost-controlling measures will successfully control Yuchai’s trade receivable balance, or that they will not adversely affect the future purchasing decisions of Yuchai’s customers. As of December 31, 2017, Yuchai had net trade and bills receivables of RMB 7,030.2 million, representing 43.9% of our consolidated current assets. As of December 31, 2018, Yuchai had net trade and bills receivables of RMB 7,387.8 million (US$1,104.3 million), representing 45.0% of our consolidated current assets.

Export Sales

Yuchai exports a very small percentage of its products directly outside China, as the following table indicates:

Note:

Most of Yuchai’s products that are exported outside of China are sold indirectly through third party distributors who purchase them from Yuchai and resell them on to end-users in subsequent and separate transactions. All of these distributors are separate legal entities in which Yuchai has no equity interest in or control over and Yuchai relies on self-reporting by these distributors in relation to their sales. In 2018, the top five export markets of Yuchai (in descending order) comprising both direct sales as well as sales through third-party distributors were Myanmar, Philippines, Vietnam, Laos and Cuba. In 2017, the top five export markets of Yuchai (in descending order) comprising both direct sales as well as sales through third-party distributors were Vietnam, Cuba, Laos, Russia and India. In 2016, the top five export markets of Yuchai (in descending order) comprising both direct sales as well as sales through third-party distributors were Vietnam, Myanmar, Philippines, Ghana and Thailand.

In February 2014, Yuchai appointed China Auto Caiec Ltd. (formerly known as China Automotive Industry Import and Export Co., Ltd.), a company based in China, on an exclusive basis for two years to export Yuchai’s products into Cuba. The agreement requires China Auto Caiec Ltd. to use best efforts to export more than 1,500 units (whole engines or parts) per year. The agreement was automatically renewed under its terms on February 16, 2018. In 2018, 1,124 engines had been sold to Cuba pursuant to this agreement, representing 0.3% of our total unit sales in 2018.

Customer Service

Yuchai believes that customer service is an important part of maintaining its market competitiveness. In addition to various services provided initially at its sales offices, Yuchai has a nationwide network of authorized service stations in China that provide repair and maintenance services, spare parts, retrofitting services and training to Yuchai’s customers. To ensure a consistently high level of service, Yuchai trains the technicians at regional training centers or selected service stations. In addition, Yuchai also owns and operates repair training centers. The costs of any warranty-related services or repairs are borne by Yuchai, and all non-warranty activities are charged to customers. Yuchai’s customer service program emphasizes a fast turnaround time on repair requests. As part of this policy, Yuchai supplies authorized service stations with spare parts for repairs and require these service stations to provide on-site assistance at the customer’s place of business generally within three to 12 hours, depending on the customer’s location.

Yuchai’s warranty obligations vary depending upon the warranty type and such provisions are determined at fiscal year-end based upon historical warranty cost per unit of engines sold adjusted for specific conditions that may arise and the number of engines under warranty at each fiscal year end. See “Item 5. Operating and Financial Review and Prospects — Critical Accounting Policies — Product warranty obligations.”

Trademarks

The State Holding Company owns and maintains Chinese trademark registrations of its principal trademarks. Yuchai has entered into trademark license agreements with the State Holding Company according it the right to use these trademarks. Yuchai believes that the Yuchai logo is well recognized as a quality brand in China.
