1. 前言

为了实现股东价值最大化，公司从事财务风险控制的做法，如果这种做法开始实施，并且创造了股东所渴望的价值，就会增加公司的价值。增值的产生有两个来源，如下所示：

(1)尽量减少财务困境成本的税金

(2)尽量避免这种情况：由于公司缺乏项目实施的资金，放弃了可能对公司带来利润产生积极影响的项目。

为 了实现股东价值最大化，我们需要作出一些行动。我们需要提出规避风险的假设，即经理将寻求最大限度地发挥自己的个人能力进行管理。这意味着，从事金融风险控制的管理人员必须以股东的利益为代价。特别是直接利益获得的股东并不是追求风险管理策略的管理人员的时候，这将直接影响股东个人财富，利率，商品价格或外币现金的价值变化。这些措施是可以采取的，不考虑股东的利益和这些措施可能带来的后果。因此，无论是最大化股东价值或财务风险控制驱动力，风险管理实践 的参与是必须遵循的。金融风险来自于给定对手的能力，及履行其义务的不确定性，这些对手是多类型的，包括服务行业的公司。扩大各种形式的义务意味着金融风险控制已经成为风险控制活动考虑的重中之重。这些做法最重要的形式是金融风险控制，特别是汽车行业的公司而言(博德纳尔，2005)。
 

特斯拉汽车公司，作为硅谷的公司，拥有设计，生产和销售电动汽车和电动汽车的动力组件。特斯拉汽车公司是一家上市公司，该公司已在证券交易所得到了广泛关 注。特斯拉在汽车行业是特斯拉跑车的第二个模型和第一台全电动跑车。其S型的全电动豪华轿车，虽然仍然是昂贵的，它基本上是一个便宜的跑车。特斯拉还销售 电动组件，包括锂离子电池组，以及其他汽车制造商戴姆勒和丰田所需组件。可以设想，作为一个独立的汽车制造商，特斯拉生产的全电动汽车的经济实惠是普通消 费者能够消费得起的(Glaum，2007年)，同时还能提供较高的质量保证。
 

本研究的目的是要提供一些这方面的答案。更具体地说，它的目标是揭示特斯拉汽车公司在汽车行业财务风险控制的状态。
 

1. Introduction

To maximize shareholder value, the company engaged in the practice of financial risk control and increased the value of the company if it was done and created for value of our shareholders by implication. Value-added generated by two sources as follows:

(1) to minimize taxes of the costs of financial distress

(2) to minimize the possibility of the company that may be forced to give up a positive project because of its lack of internally generated funds to do so.

Opposite to maximize shareholder value, it is the management of risk aversion hypothesis that the manager will seek to maximize their own personal well-being. This means that the management staff at the time, engaged in financial risk control for practices at the expense of shareholders. Especially when the shareholders of interests are not exactly the same managers who may pursue risk management strategies, and it is changed in their personal wealth, interest rates, commodity prices or the value of foreign currency cash. These steps can be taken, regardless of the wealth of the shareholders of the consequences of those decisions. Therefore, whether to maximize shareholders’ value or financial risk control for driving the participation of force in risk management practices that must be followed. Financial risk arises from the uncertainty in a given counterparty's ability to meet its obligations. More types of opponents and expanding various forms of obligations means that the financial risk control has arrived to the forefront of risk control activities in the service industry companies. One of the most important forms of these practices is related to financial risk control, especially for the companies in the automotive industry (Bodnar, 2005).
 

Tesla Motors, as a Silicon Valley company, possesses design, production and sale of electric vehicles and electric vehicle power components. Tesla Motors is a publicly traded company, which has been widespread concern in the stock exchange. Tesla in the automotive industry is the second model of the Tesla Roadster and the first all-electric sports car. Its s-type is all-electric luxury sedan. Although still expensive, it is basically a cheaper sports car. Tesla also sells electric power components, including lithium-ion battery pack, and the other carmakers are Daimler and Toyota. It is envisioned as an independent car manufacturer that is special for Tesla with the final quality of the production of all-electric vehicles at affordable ordinary consumers (Glaum, 2007).
 

The purpose of this study is to provide some of the answers in this regard. More specifically, its goal is to reveal the state of financial risk control for Tesla Motors in the automotive industry.
 

2. Main Body
 

2.1 Tools for financial risk control

With the tips in some cases through regulatory tasks, other financial institutions have been looking for new means to measure and control its financial risk. Adding fuel to the fire carried out a series of related activities, it involves the rapid pace of product innovation, further financial institutions to diversify into new geographic and product markets area, as well as an enhanced credit intermediation rate. The effect has been that we have witnessed the development of more sophisticated financial risk measurement and management methods. It has been the introduction of more complex hedging method. Even more interesting, especially interested in, it has been the development of the model that can be used to migrate to measure financial risk at the portfolio level, and it can also be used to allocate the capital. These can be broadly divided into two types; proprietary financial risk control models and the vendor's sales model. Despite the nature of their general application, it is almost universally quite complex. As clear reasons, there is not enough information you can get about the ability for the former category of these models. However, some of the details are generally the latter category. This category includes financial risk control models as follows.
 

First, for JP Morgan sales, its financial risk control is one of the first model portfolios and developed for the assessment of financial risk. It incorporates a method for evaluating changes in counterparty financial quality of the portfolio's value-at-risk generated. It establishes a risk profile for each counterparty portfolio and combined with the volatility of individual instruments to model the volatility of the total portfolio. The loan loss reserve sets methods to make it assess the risk capital illiquid loans environment. Therefore, the method may be better suited for a company whose loan portfolio of retail and institutional rather than those bonds (Fatemi, 2009). In addition, as a loan pricing corporation, KMV portfolio manager measures the risk and return characteristics of the portfolio, and allows users to explore personal assets at risk to change the incremental effect. It also provides a large combination of changes to assess the potential changes and inspection of the tactical and strategic effect. It can be a valuable tool to determine the allocation of the total capital requirements and economic capital (Luck, 2011). Finally, McKinsey Company financial risk concept is achieved in default, and the financial risk control is estimated in specific countries and industries. It uses the default rates of speculation into national and industry-specific global macroeconomic development. It then maps these price cumulative probabilities of migration by country and industry (Howton, 2010).
 

This brief description of these models have shown that increasing the complex of financial risk control has been caused by the same set of complex design models to measure and manage the risk. Then it is to provide a picture of financial results for Tesla Motors in the United States using these models as above.
 

2.2 Financial risk control for Tesla Motors

Income for the second quarter of 2011 was $ 28.4 million, which is a 36% increase than in the previous quarterly report. The gross profit margin increased to 22%, including 19% from the previous quarter and 8% from the second quarter of 2010. The net loss for the quarter to $ 29.5 million, compared to the previous quarter to $ 38.5 million. It is reported that higher gross margins and stable top-line growth are driven by the best quarter since the third quarter of 2009, with new sports car orders and growing power activities. It is shown that people can drive the beautifully designed and high-performance electric cars, and it stressed Tesla's technology leadership. With respect to the S-type development, it can make its components and vehicle production for facilities in Tesla Motors (Dolde, 2005). However, there are certain risks and uncertainties, and actual results may differ materially from those projected. Following important factors, it could cause actual results and different material with these forward-looking statements: consumers are willing to adopt electric vehicles and Tesla's electric vehicles, especially Tesla's ability to draw down of facilities related to the risk of the U.S. department of energy. Tesla is able to execute its planned development, production and marketing and sales of the planning mode trumpet electric car, in order to reduce the cost of full control and management of its business and competition in the automotive market generally and the alternative fuel vehicle market, especially by establishing, maintaining and strengthening the brand. Although Tesla Motors has its cutting-edge technology, and many of its competitors have several generations for people, and be able to achieve production efficiency of facilities, the Tesla Motors can only fall over itself at this point. In addition, they also have a comprehensive network of services and strong customer loyalty. According to these data, Tesla Motors’s financial position seems relatively stable, but its future health is heavily dependent on the successful model of S. As of now, they have a loan facility of up to $ 465 million and have raised about $ 480 million dollars in funds from the stock issue. Start in December this year to repay the loan, which may have a direct impact on mobility. Management believes that it will meet the needs of working capital, cash inflow generated in the case of sales shortage of the Model S, and there is always the possibility of another stock issue, although this is not a desirable option (Mian, 2009).
 

3 Discussion
 

From the above analysis, it can be quite easily seen that other companies in the automotive industry use or intend to use the internal financial risk control model. Interestingly, with only one exception, Tesla Motors use its own proprietary models financial risk control and can also use the supplier sales model. Therefore, it is used for financial risk control, through an internal model and proprietary one, but also to be done so. The most widely used models on the market are the second type between the proprietary models, but others are not widely used. In addition, it seems wider for the use of these non-models trading than their trading bonds.
 

4 Conclusion
 

In this paper, it can be found that Tesla Motors in the automotive industry determines the financial risk control by taking advantage of models as above. Nearly half of the models surveyed are able to deal with the financial risk. Surprisingly, only a small number of the models are used for proprietary or vendor sales risk model. Interestingly, those who use their own internal models also use the vendor's sales model. Overall, it is a wide application of these models for financial risk control.
