The legislative intent is that policyholder obligations and the minimum capital or guaranty fund and surplus required by law must be covered only by assets of unquestioned integrity and stability and that assets in excess of those required to cover policyholder obligations, minimum capital or guaranty funds, and surplus may be invested by insurers at the discretion of the insurers. However, the assets must not be invested in assets prohibited under Section 38-11-90. The purpose of this section is to protect and further the interests of policyholders, claimants, creditors, and the public by providing standards for the development and administration of programs for the investment of the assets of companies organized under this chapter. These standards and the investment programs developed by companies must take into account the safety of the company's principal, investment yield, and growth, stability in the value of the investment, and liquidity necessary to meet the company's expected business needs, and investment diversification.
