OBJECTIVES: Taiwan’s National Health Insurance, established in 1995, has offered every citizen nearly equal financial access to comprehensive health services and provides all citizens with financial risk protection from large medical expenses. Existing data reported that purchasing private life and annuity insurances is popular in Taiwan, with an average of 2.3 contracts per person and 18% of GDP invested in life insurances, ranking #1 worldwide in 2012. For individuals who purchase private insurances to add protections it is natural to ask which insurance policy provides the most favorable return. The objective of this study is to establish a valuation system for private life and annuity insurance plans using a robust, flexible, distributed cloud computing architecture. METHODS: Using the fixed income model and by constructing polynomial interpolated yield curves from Taiwan government and corporate bonds, we can approximate the internal rate of returns of each insurance policy and compare their performance versus the time value of money of the total investments. We extracted daily information from over-the-counter markets and Taiwan interbank interest rates to compute daily changes in policy values. RESULTS: Shown in our experiments, by investing in insurance policies from 30 to 85 years old, the policies provide -0.1% to -1.4% returns, which represents the total value of investments has diminished throughout the years. Even in the event of benefit claims (severe injury or death), the insurances provides -0.2% to 1.5% returns. For annuity insurances, early investments do not provide advantages, i.e., by investing at 30 and by 50 years old, the returns is approximately the same at 85 years old. CONCLUSIONS: We establish a robust, flexible and efficient valuation system for private life and annuity insurance plans. Results show that even by purchasing private insurances, the extra protections provided is still inadequate to cover major emergency medical conditions.
