An Investment Management Methodology for Publicly Held Property/Casualty Insurers

Investment officers of publicly held property/casualty companies wrestle with the question of how best to contribute to shareholder value. Should they view themselves as managers of a closed‐end investment company that happens to be funded by insurance underwriting? Or should they instead be investing funds primarily to defease the firm's liabilities and thus support the operations of a company whose principal value derives from its insurance activities? The authors of this article suggest that the investment policy of most insurance companies should have two primary objectives: (1) immunizing insurance reserves with a fixed‐income portfolio and (2) earning “abnormal returns” on surplus in “a responsible and disciplined” way. The latter means adhering to an asset allocation approach that takes account of the risk‐reward tradeoffs presented by a broad variety of investment types as well as the accounting treatment of investment income. Both accounting and economic considerations lead the authors to suggest that after‐tax net investment income (“NII”), as defined by U.S. GAAP, is the best benchmark of performance. While focusing mainly on the fixed income part of the portfolio, the authors suggest active management and portfolio approaches that aim to produce a growing, but relatively stable NII. Consistent with GAAP's treatment of NII (which includes interest income but excludes most capital gains) as “recurring income,” the authors argue that the market appears to assign significantly higher multiples to NII than to other sources of reported income.
