The adjustment of security returns to the disclosure of replacement cost accounting information

In March 1976, the Securities and Exchange Commission (SEC) promulgated Accounting Series Release No. 190 (ASR 190) requiring the disclosure of certain replacement cost (RC) accounting data by its registrants. The purpose of this study is to assess whether the RC disclosure rule had any effect on common stock returns for firms affected by the new rule. Distinguishing the effect of compliance costs from the effect of information in the RC data, we found no sign of a cost effect and no strong evidence of an information effect. This result appears to imply (a) that the burden of the ASR 190 compliance costs was not large enough to induce downward adjustments of the firms' security returns; and (b) that the RC data did not provide new information useful to investors as asserted by the SEC.
