Data and Empirical Result<br />
With Taiwan’s listed and OTC enterprises <strong>of</strong> the in<strong>for</strong>mation industry traded on Taiwan Stock<br />
Exchange in the period from January 1990 to December 2011 as the research subjects, this<br />
paper explores the type <strong>of</strong> financial derivative that should be selected at various stages in the<br />
business cycle, and how to use the characteristics <strong>of</strong> such financial derivatives to avoid <strong>for</strong>eign<br />
exchange rate risk and risks arising from other factors. This paper has eliminated enterprises <strong>of</strong><br />
the non-in<strong>for</strong>mation industry, enterprises with omissions <strong>of</strong> requested variables, enterprises <strong>of</strong><br />
incomplete financial in<strong>for</strong>mation or enterprises that have been merged or delisted due to<br />
financial crisis during the research period. After the removal <strong>of</strong> such samples according to the<br />
above standards, this paper selects 344 samples. The data are sourced from the prospectus<br />
and annual reports <strong>of</strong> Taiwan’s listed and OTC enterprises, the public in<strong>for</strong>mation websites. This<br />
research is divided into four parts: the first, an introduction <strong>of</strong> the general survey <strong>of</strong> using<br />
financial derivatives at various stages <strong>of</strong> business cycle by the listed enterprises <strong>of</strong> the<br />
in<strong>for</strong>mation technology in Taiwan; the second, using the Pearson correlation analysis to analyze<br />
the correlation among variables and removing the collinearity <strong>of</strong> regression model; third,<br />
employing the logistic regression analysis to discuss the hedging tools and types <strong>of</strong> financial<br />
derivatives by enterprises; and the last using multinomial logistic to discusses how enterprises<br />
use different financial derivatives to avoid different risks and the covariance relationship arising<br />
from the use <strong>of</strong> different hedging tools and hedging effectiveness. The dependent variable <strong>of</strong><br />
this paper is the use <strong>of</strong> financial derivative <strong>for</strong> hedging with 1 denotes use and 0 denotes no use<br />
<strong>of</strong> financial derivatives. This is a discontinuous binary variable that is not suitable <strong>for</strong> general<br />
linear regression model. This paper employs the logistic model to discuss the determining<br />
factors affecting the use <strong>of</strong> financial derivatives at various stages <strong>of</strong> business cycle <strong>of</strong> listed<br />
enterprises <strong>of</strong> the in<strong>for</strong>mation technology industry. The empirical model <strong>of</strong> this study is as below:<br />
This paper also discusses how enterprises use different financial derivatives to avoid<br />
different risks and the covariance relationship arising from the use <strong>of</strong> different hedging tools and<br />
hedging effectiveness. Since the dependent variables are multiple choices, the multinomial<br />
logistic model is used as the analysis tool. In theory, this model inherits the characteristics <strong>of</strong> the<br />
logistic model to test the relationship between the occurrence probability <strong>of</strong> the dependent<br />
variables and the explanatory variables. The difference is that the dependent variable <strong>of</strong> the<br />
logistic model is dichotomy (0 and 1) while the dependent variable <strong>of</strong> Multinomial Logistic is<br />
multiple categories (0, 1, 2, 3, 4 …). In this model, the dependent variables include the types <strong>of</strong><br />
risks and types <strong>of</strong> hedging tools used by the company during the period <strong>of</strong> the empirical study.<br />
Suggestions<br />
Regarding factors affecting the use <strong>of</strong> financial derivatives <strong>for</strong> hedging by enterprises, this study<br />
uses multinomial logistic regression analysis to explore factors affecting the use <strong>of</strong> types <strong>of</strong><br />
hedging tools and hedging tool combinations by the company, findings are empirically. In this<br />
study, an enterprises with greater net operating income and ratio <strong>of</strong> <strong>for</strong>eign sales will have more<br />
interests to use <strong>for</strong>ward contracts, option or others to hedge. In case <strong>of</strong> enterprises using swap<br />
contracts to hedge, all the relevant explanatory variables are almost not significant and no<br />
conclusion has been reached accordingly. Eventually, choosing the most suitable instrument,<br />
enterprise is suggested to make certain <strong>of</strong> what its trade activities are being carried out,<br />
exhaustively estimate exchange rate, consequently, you might make the best decision.<br />
