ADDITIONAL EVIDENCE ON THE INCREMENTAL INFORMATION CONTENT OF THE 10‐K
从市场整体角度检验10-K报告是否比年报和盈利公告等提供额外信息，统计结果表明对样本公司而言，10-K报告通常没有增量信息含量。
The goal of this investigation is to provide additional evidence concerning the incremental information content of the 10‐K from the aggregate market perspective. As in Foster and Vickrey (1978), the phrase, incremental information content of the 10‐K, refers to the information content of the data set in the 10‐K which is in excess of that which is contained in the related annual report to shareholders and other preceding announcements such as earnings releases. The statistical procedures seem to imply that the 10‐K did not, in general, possess incremental information content from the aggregate perspective for the firms considered herein.
