El informe de transparencia de las firmas auditoras: Evidencia del mercado español 2010-2013

This paper looks into the Annual Transparency Reports published in Spain in 2010 as a consequence of the Spanish Auditing Act 12/2010, and in 2013 after the publication of the 2011 Spanish Auditing Regulation and the new European Union proposals. The results of this pioneer research in our country evidence a high level of transparency regarding the compulsory items legally required, showing an increasing trend from 2010 to 2013. However, there is a decrease in voluntary information in 2013. Our study reveals that bigger audit firms and firms less dependent on fees from consultancy services are the ones with higher transparency levels in their Annual Transparency Reports.
