The main method applied in the present article is content analysis. Results. On the grounds of the described research methodology, the content analysis of annual reports dated from 2010 to 2012 by Nasdaq OMX Baltic-listed companies was performed. By applying the "QDA Miner" software, intellectual capital-related terms were calculated and distributed into three categories (human, relational, and organizational) in terms of the assets and liabilities. The obtained results of the three countries were compared in order to reveal the trends of development; furthermore, a correlation analysis was conducted to reveal the relationship between the market capitalization of a specific country and the level of disclosure on the intellectual capital of enterprises.

The highest amount of information was revealed by Lithuanian enterprises and the lowest amount is shared by Estonian enterprises. The best-covered information on the intellectual capital presents the employees as an asset while the most scantily revealed information describes intellectual liabilities. J.
