This thesis is to estimate the Cash-Flow-at-Risk (CFaR) for the case of Motech Industries, Inc, a well known solar-power battery manufacturer in Taiwan. We follow the steps of the Corporate Metrics method developed by J.P. Morgan. At first, in order to express the risk exposure, we collected the three major cash flows, i.e., operating , investing activities, and financing ones, from the financial statements of Motech Industries, Inc. , which is shown in the website of the Market Observation Post System. The unit-root test results indicate that the three CFs there are not co-integrated among themselves. Therefore, we adopt the vector auto-regression model (VAR model), instead of Vector Error Correction Model (VECM) suggested by J.P. Morgan, to estimate the cash-flow forecasting equation. This estimated relationship includes five external risk factors, which allows us to forecast the three CFaRs by Monte Carlo simulation.
The sample period of Motech’s CF data includes from the second quarter in 2002 to the first quarter in 2011, a period of 36 quarters in total. We also collected for the same period the data of five external risk factors including the price of oil, the exchange rate of US dollar, the price of electricity, the price of multi-crystal silicon material, and the price of solar module. The estimates of CFaR are NT $1,026 in millions for a 5% level of significance and NT $1,455 in millions for a 1% level of significance. The actual value of CFaR is unknown because the financial statement of Motech Industries, Inc. in the second quarter in 2011 is still un-publicized yet when this thesis was finished.
