The study employs factor analysis and logistic regression (FAST approach) to estimate the probabilities of insolvency of Taiwan's life insurers. Our findings show that changes in the fixed asset ratio, changes in the liquid asset ratio, and changes in loan ratio are important factors for Taiwanese life insurers' insolvency. Therefore, the commissioner should focus on these financial ratios. This study presents that almost 10 percent of life insurers in Taiwan have a problem of insolvency.
