The Role Analysis for the Shareholding Structure to Risk Control in Public– Private Partnerships Xing Bi1, Jing-xing Chang1 1 College of Management and Economics, Tianjin University, Tianjin, China (bistar@126.com) II. METHODOLOGY Abstract - The PPP (Public-Private Partnership) model has become increasingly important as a means of financing the construction of infrastructure, but it has many special characteristics, such as a large investment, long construction period, involving many partners, and the complex contract structure relatively. This makes the project risk control extremely important, which also is the key to success. Through a detailed literature analysis, first of all, the paper points out the main points of risk control with twodimensional analysis of the risk, and determined both public and private risk allocation coefficient according to the equity structure, and then the control was given the most advantageous risk control side according to the shareholding structure adjusted, in order to achieve the new ideas for the purposes of risk control. Keywords – PPP, risk control, ownership structure I. INTRODUCTION PPP (Public-Private Partnership) is a way of supplying Public products, which between outsourcing and privatization and combines both those characteristics, which makes full use of private resources for the design, construction, investment, operation and maintenance of public infrastructure, and provides related services to meet public demand [1]. PPP Project financing allows private capital to become more involved in the project. Considered the government's public sector and private sector concession agreement as the basis for the full cooperation, both sides are responsible for the entire cycle of operation of the project to improve efficiency and reduce risk. But generally the PPP project requires a large investment and long time, faced with high-risk. The contract structure is relatively complex and the project negotiation process is often protracted [2]. There is often a controversy, as a result of being unable to deliver on promises in the implementation process or some other reason, so that only a small number of PPP projects can operate normally in practice among them. The main reason is the lack of fair and reasonable risk-sharing between public and private sector standards and it is difficult to drive both sides industriously to control risk allocated [3]. Consensuses on the principle of risk allocation have been reached [4], but the concrete implementation of the risk incentives and risk-control is still an urgent problem in the PPP project. A. Two-dimensional analysis for risk Relative to the general project, the PPP project with long construction period, involving the public sector, private sector, the project company, bank financial institutions, insurance companies, engineering construction, contractors, engineering consulting companies, suppliers of equipment and materials, the project products (services) buyers and many other parties, and the contractual relationship between the parties is more complicated[5]. This will undoubtedly increase the risk of the project, which has brought many challenges to the smooth implementation of the project. Project risk control has become a bottleneck in the development of the PPP mode. Good risk control stems from a clear understanding of risk [6]. For risk control study, the paper analyses the project risk from the two dimensions including the project stage and the type in-depth to lay the foundation. From the view of project process, the risk exists in the whole process and stages of the project. General project is divided into seven stages: feasibility study stage, bidding stage, the organizational phase of the contract, financing stage, the project construction phase, the project operation phase and the project transition phase. In this paper, the first three stages are collectively referred to the project early stage. The different stages have different risk characteristics and risk control points [7]. According to risk types, the risk also is divided into political risk, construction risk, operational risk, market risk, legal risk and financial risk [8]. Two points method are not independent each other with a different classified way of the same risk (see Fig.1). Each risk does not just exist at a certain stage; every stage does not just have a type of risk. Such as: the rising risk of market risk in the cost of materials present in the construction phase, but the market demand, the only competition in the market risk does exist in the phase of the operation. Meanwhile, the same stage of construction is not only market risk, but political, financial and other risks. These two division methods benefit from the perspective of two-dimensional understanding of risk, which can identify the main risks of the various stages and the generic of risk at this stage. Thereby increasing the sense of three-dimensional understanding of the risks, which contribute to more clearly identify who have more advantages to control risk in order to better allocate and control risk [9]. Early stage Political Financing stage Construction Project construction Operation Market Operation phase Legal Transition phase Financial Fig.1. Two-dimensional analysis for risk The complexity of the risk we can not only singly control a certain stage, but also do with the type of risk, analysis of both the sources of risk, and thus determine the risk control methods. How to achieve effective control is the focus of this study. B. Risk allocation principles For the principle of risk allocation of the project academia has reached a consensus [10]: who have the best power to the risk to bear the corresponding risk. Thus, when the risk occurs, we first determine the stage of the risk and generic the risk of, determine who control this risk, which means who in the best position will reduce the probability of the occurrence of the risk and the losses caused. Meanwhile, who have the power to control risk would be derived him to manage the risk industriously. In accordance with the principles on the allocation of these risks, construction risks should be allocated to the private sector because the private sector in the best position to control the construction process of the project; some risks, such as political risk, the risk of legal changes and nationalization risk, should to be beard by the public sector with more control. Because the public sector, as a government or government representatives, has the ability to influence the rules and regulations, policies, laws and other regulations. Therefore, it is in a more favorable position than the private sector to identify, evaluate and control these risks. III. DISCUSSION A. The impact of ownership structure on risk allocation Reasonable risk allocation principles, the most favorable control side of the risk needs control power that matches the risk and the proceeds corresponds to risk to excited its risk control initiatively. Control and equity are inseparable. The project company's ownership structure or investment structure reflects the shareholders 'legal rights to interests of the project assets and legal contractual relationship between the shareholders each other. Under the constraints of the project site laws and regulations, accounting and tax and other objective factors, it is one of ownership structure of assets of projects to achieve the shareholders' investment objectives [11]. How much equity represents how much control, and it also represents a party to the risk control ability. This paper tries to discuss the risk control from the ownership structure perspective. First before the start of project, both public and private determine their own risk allocation through particular negotiations. Generally, the risk which is able to identify which side is more advantage to control is borne by the appropriate parties, the one, which is difficult to identify which side is more advantages to control or both sides do not have the advantage of risk control, should be allocated in accordance with the accounting for interests in shares by the two sides. Then the risks borne by the private party can be divided, and generally private parties are composed by the Joint Venture, each participating enterprise have professional advantage at one stage. Giving it control power by reasonable adjustments of the ownership structure in the course of the project, so as to achieve the incentive to fully play their own advantages to control the risk(see Fig.2). Under the guidance of the principle of risk allocation, the problem of the risk allocation becomes to distinguish who have more control power to risk. Found by comparison: 1) the private party shall bear the risk of project financing, construction, procurement, operation and maintenance; 2) The Government should undertake public policy, law changes and other risks; 3) force majeure risk which is not good to determine which side to take the risk, should be a mutual undertaking. We set the risk distribution coefficients A, B, C, and A + B + C = 1. A represents the risk distribution coefficient of the Government, B represents the risk distribution coefficient of the Government, C represents the risk of both the government and the private side shared. C sector would redistribute according to the ownership structure of the entire project. If private parties invested in M, and government-funded N, the private party equity accounted for K = M / (N + M), then 1-K for the government. The ultimate risk of the partition coefficient of the private side is X1 = A + K * C, for government departments, the allocation of risk factor is X2 = B + (1-k) * C. Then the allocation coefficient of risk are linked to final income with the project, the more coefficient and more higher income distribution in order to achieve the purpose of incentives to control risk. Total risk The first distribution The risk of government control The second distribution The risk of private control A Company B Company C Company Fig.2. Risk allocation flow B. Private party risk redistribution Through the allocation of these risks, the private parties determine the risk of their own to bear. The private party is a coalition of several enterprises generally in the PPP project, each one has its own expertise areas, and general project has Stage characteristic of financing, construction and operational phases. The implementation of project will benefit from professional advantage. Faruqi and Smit think that sharing the PPP project company with contractors and equipment suppliers and other professional firms will benefit the project on schedule, completion of standard quality to achieve business, give full play to the already existing experience in the actual operation and improve operational efficiency [12]. Zhang points out that the construction and finance are two risk types of PPP projects, the government and the creditors are very concerned about the project shareholder structure, and that the shareholders who tend to achieve profit-sharing of project is to be more conducive to the implementation of the project [13]. Yescombe think that it will effectively reduce the financing costs, improve financing efficiency that the cooperation between the dual identity of investors for short-term interest, such as the construction contractors, equipment suppliers, and those pure investor who are interesting in long-term benefits of the project [14]. Xu Xiaodong and the Chen Xiaoyue points out that the changes in the company's largest shareholder is in order to obtain the benefits of control, It is conducive to the improvement of the effectiveness of corporate governance, enlarged scale and more specialized management [15]. Combining of existing research results, the advantages of company shares will play their strengths to control projects risk in the stage of financing, construction and operation, reduce risk probability and ensure the successful implementation of the project. To this end, it is a good way that can be taken to encourage private consortium enterprises by restructuring equity structure according to the process of the project. Assuming that the private joint venture contains investment management company (A), Construction Company (B) and operating companies (C), every company has the different proportion of equity in different stages of the project. Company keeps the absolute ownership (shareholding> 50%) in its best control stage, meanwhile, and the distribution of income is directly related to the equity proportion in order to motivate the purpose of risk control. Specific actions: firstly, A keeps the concentrated ownership in the financing stages in order to reduce higher financing costs risks. For the construction phase, the ownership is concentrated hold by the Company B, using its own experience and technological advantages to control construction costs, completion date, quality of the project and other risks in the field of construction. Finally to the operational phase, the ownership is concentrated hold by the Company C which has the most advantage to control risk at this stage. The entire equity interest in the conversion process could be the associates within the body of equity transfer agreement (see Fig.3). Financing stage Project stage A>50% B<50% C<50% A<50% B>50% C<50% Operation stage A<50% B=0 C>50% Fig.3. Make the ownership structure adjustment according to the stage of project REFERENCES IV. CONCLUSION PPP project model can effectively reduce the burden on public finances to optimize the fiscal expenditure configuration, the introduction of advanced technology and management experience, and improve efficiency. There is a wide range of applications, covering the field of transportation, power plants, water supply, sewage / waste disposal, medical, national defense, prisons and police. However its risk control issues become more prominent than the average one, which has become the bottleneck in the development of PPP projects. Starting from the twodimensional analysis of risk, the paper raises both public and private to accept risk which mainly be allocated in accordance with the division of the types of risks, every company of the private parties bear the risk of secondary distribution which is to be allocated in accordance with the project process. Combining equity restructuring and risk allocation, there is to incentives and give the most advantage risk controlling party absolute control power in order to achieve the best risk control purposes.
