Investor protection lies at the heart of the PCAOB’s statutory mission. We accomplish that mission by promoting high-quality audits through our standard-setting, inspections, and enforcement programs. As part of our mission, we also aim to provide relevant information to investors and to engage with them on PCAOB activities that may be of interest.

The Office of the Investor Advocate was established to help the PCAOB Board incorporate investors’ perspectives in the PCAOB regulatory agenda and enhance the PCAOB's engagement with investors and investor advocates.
