The aim of this study was to test the assertion of New Zealand company directors that CCA information was not useful for investor decision making. Subjects made investment decisions based on their predictions concerning two similar, real (identity disguised) companies. These decisions and other evaluations were made in a post-test only, control group design experiment. CCA's relevance and reliability according to particular definitions of these characteristics was thus assessed. The results show that current cost accounts are more useful for investor decision making because they are both more relevant and perceived to be more reliable than conventional historical cost accounts.
