The analysis has also been focused on the company's attitude to overcome the financial crisis. Secondly, the authors have analyzed if the recovery project has required the introduction of a new management control system or changes to the existing management control system. The methodology is composed of several steps. First of all, the authors have analyzed the existing literature. Secondly, the authors have referred to a sample of 98 Italian recovery projects formalized by Italian private companies. The analysis of the literature and the recovery projects permits to achieve some provisional results, which have been tested through surveys. The methodology approach is inspired by the grounded theory. The findings have been several: (1) The crisis is a usual event in the lifecycle of a firm, due to a deterioration of its strength and a change of the context; (2) The timing factor has played a fundamental role in managing the crisis situation, because a late identification of the symptoms or a minimization of them can generate an irreversible situation; and (3) In addition, a recovery project includes the introduction of a new management control system or changes to the existing management control system. These new or modified management control systems use "feed-forward" mechanisms, which make early predictions about the changes in the characteristics of the competitive framework.展开更多

Cycles of the core macroeconomic environment is each enterprise that must face the reality of the problem, for the listed companies, the macroeconomic environment is set up financial strategy need to consider problems listed companies must be good at making scientific financial strategy to avoid and reduce the negative influence of the macro-economic changes. Under the condition of the socialist market economy, as the listed company financial management is to maximize the value of the company ultimate goal. Our research combines the registration system background to propose the novel perspective that is meaningful.展开更多

Managers should give more attention to the establishing of reform institution and the supervising of company capital system' s operation in the process of reform. Managers should also attach great importance to the third party and creditors when they value the interests of shareholders. It is imperfect to only emphasis or value the interests of the shareholders or the third party and creditors. In addition, creditor' s self-protection of civil action should obtain much more approaches in the process of reform.展开更多

The model is a multistage stochastic programming which considers transaction costs, cash flow between time periods, and the matching of asset and liability; it does not depend on the assumption for normality of return distribution. Additionally, an investment constraint is added. The numerical example manifests that the multiperiod model can more effectively assist the property-liability insurer to determine the optimal composition of insurance and investment portfolio and outperforms the single period one.展开更多

According to static game model, it re-vealed that the reason for low compliance rate of "company + farmer" model was the existence of market risk, namely, the fluctuation of market price, and the stable market price in contracts was actualy a kind of interval, instead of a specific value. Furthermore, the effect of default penalty, market transaction cost and time prefer-ence cost on the stability of contract was studied. The results showed that default penalty, market transaction cost and time preference cost had positive influence on the price interval range of a contract.展开更多

In response to the recommendations of G20, Financial Crisis Advisory Group (FCAG), and other international bodies, the International Accounting Standards Board (IASB) has undertaken, since 2009, as a part of the project to replace IAS 39, a project (partially shared with Financial Accounting Standards Board (FASB)) aimed at introducing an expected loss model of impairment. Within the scope of this subset project, the IASB has previously issued two exposure documents proposing models to account for expected credit losses: an exposure draft (ED) Financial Instrument: Amortized Cost and Impairment, published in November 2009, and a supplementary document (SD) Financial Instrument: Impairment, published jointly with the FASB in January 2011. However, neither of the two proposals received strong support from interested parties. Recently, the IASB, after the FASB's decision to withdraw from the joint project and to develop a separate expected credit loss model based on a single measurement approach consisting in the sole recognition of lifetime expected credit losses, published a third proposal--Ahe so-called expected credit losses model (ED/2013/3 Financial Instruments: Expected Credit Losses).展开更多

文摘Oil and gas exploration and production is the most important and key segment in the whole business chain of the petroleum industry.Therefore,oil companies always put much emphasis on making scientific and reasonable decisions about investment scale and structure in the upstream sector,so that they can minimise business risks and obtain high returns.According to the system dynamics theories and methods and based on the actual results from an oil company's practice in China,a system dynamics model is built in this paper for analyzing and forecasting the upstream investment scale and structure for an oil company.This model was used to analyze the investment effect of a large oil company in China, and the results showed that the total upstream investment scale will decline slowly in a short period and the investment proportion of different parts should be adjusted if some influencing factors are taken into account.This application practice was compared with the actual data and indicated that the system dynamics(SD) model presented in this paper is a useful tool for analyzing and forecasting of upstream investment scale and structure of oil companies in their investment decisions.
