Abstract. Solvency margin of Thailand has been using maximum of 2 percent of statutory reserve or 50 million baht (whichever is higher) as a required capital in order to absorb unexpected large loss for the sake of solvency in Life insurance industry while modified net level premium has been adopted to establish statutory reserve. Investment securities and market environment tend to be more complicated, simple and traditional monitoring may not be able to guarantee solvency of Life Insurance Company in future. As such, Thai regulator recently has planned to develop new solvency margin for Thailand by using risk-based capital concept to implement in Life insurance Company, which is operating in Thailand.

As a part of The Society of Actuaries of Thailand, this paper tends to assist Thai regulators to observe risk-based capital model as well as its history and development in Life insurance industry. Risk-based capital models developed from various countries during past several years are also observed as a stable benchmark. With author opinion to provide advantage and disadvantage from each model, it also recommends what can be holistically achieved and positioning for upcoming development of new risk-based capital of Thailand so as to encourage well risk management practice while having effective model but not too complicated to implement by Life insurance industry in Thailand.

What is Capital?

Capital is the surplus from the balance sheet. It is the excess of the asset less liability. In short, Asset less Liability equal to Capital. Capital in fact is injected from shareholder or investor or entrepreneur since inception of the company.

As a matter of fact, the advantage of the form of corporation is that if Liability is more than Asset, the Capital would be depleted to zero, not negative. This means that the obligation from liability will not be able to be paid in the end.
