| Summary: | 碩士 === 中原大學 === 會計學系 === 87 === The pension accounting was implemented in 1995. There still exists some room for discretion. The purpose of this study is to examine whether or not managers adjust the pay combination and (or) manipulate actuarial assumptions to cut down the pension cost and pension liabilities.
Differ with pay combination will effect the pension cost and liabilities. We divided the sample into two groups (adjust the pay combination or not) by the questionnaire. Adjust the pay combination for pension accounting is not full of earnings manipulation. Manipulate actuarial assumptions rather than adjust the pay combination that is to manipulate earnings.
We apply a simultaneous model on a sample consists of 143 firms listed on the Taiwan Exchange for the year 1996. Results of the study are summarized as follows:
1. Companies with more employees tend to adjust the pay combination to cut down the pension cost and pension liabilities.
2. In all samples, companies with longer history, earnings worse, tend to manipulate actuarial assumptions to cut down the pension cost and funding status. In the sample of adjust the pay combination, we find coefficient of the variables except the employees to meet the expectation that is not manipulation. In the sample of unadjusted the pay combination, we find more coefficient of the variables to meet expectation that companies with longer history, more employees per firm, earnings worse tend to apply lower rate of increase in salary.
3. When the purpose of study is to examine whether or not managers manipulate earnings should be taken off the sample that companies adjusted the pay combination.
