The first objective of this study is to describe the substantial differences across property-liability insurers in accounting classification decisions for fixed maturity securities during 1991–1995. This period includes the years before adoption, upon initial adoption, and after adoption of Statement of Financial Accounting Standards No. 115 (FAS 115, “Accounting for Certain Investments in Debt and Equity Securities”). The second and more important objective of this study is to test two risk-based explanations for differences in investment classification decisions under FAS 115. Under this new standard, firms are required to classify fixed maturity investment securities into trading portfolios, available-for-sale portfolios, or held-to-maturity portfolios. These classification decisions determine whether these securities are recognized at fair value or historical cost. On one hand, the decision to classify securities as available-for-sale rather than held-to-maturity (and thus apply fair value accounting) increases the time-series volatility of key accounting numbers such as owners' equity and total assets, which may be costly for insurers with low tolerance for accounting volatility. On the other hand, the choice to classify securities as available-for-sale (and thus apply fair value accounting) reduces liquidity risk because the accounting standards (and SEC enforcement practices) limit management's ability to sell securities that are not recognized at fair value. The empirical analyses examine whether the security classification decisions of the sample property-liability insurers are associated with firm specific characteristics that reflect liquidity risk and the tolerance for accounting volatility. The findings show that managers of property-liability insurers make tradeoffs between liquidity risk and concerns about accounting volatility when making investment classification decisions under FAS 115.
