| Summary: | 碩士 === 國立政治大學 === 會計研究所 === 93 === The paper uses the empirical method to examine the value relevance of a company’s deferred tax assets from tax loss carryforwards which respond to the stock price. In addition to the positive effect of deferred tax assets from cumulative tax loss carryforwards, representing the “asset” valuation to save the future tax, the paper finds the negative effect of deferred tax assets from the contemporary tax loss carryforward, which respond to the stock price. The paper uses the incremental value of deferred tax assets from the contemporary tax loss carryforward as a specific variable and two dummy variables, whether the operating loss happens this year and the number of effective periods of unused tax loss carryforwards, to examine the effect of deferred tax assets from the contemporary tax loss carryforward. The empirical result finds that the variable, the incremental value of deferred tax assets from the contemporary tax loss carryforward, and the dummy variable, whether the operating loss happens this year, are significantly negatively related to the stock price in statistics, but the negative effect of the dummy variable, the number of effective periods of unused tax loss carryforwards, is not attested in statistics, with a possible reason of more or less than one effective period of unused tax loss carryforwards.
