The Public Company Accounting Oversight Board is forming a new advisory group, this time focused solely on investor interests.

The board is forming an Investor Advisory Group to “obtain the views and advice of experts who have a demonstrated history of commitment to investor protection,” according to the advisory group’s charter. The board is accepting nominations immediately.

The PCAOB already has a Standing Advisory Group that serves as a sounding board on various audit issues, but that group represents a broad spectrum of capital market expertise. Members include, for example, auditors and corporate executives who are subject to the board’s rules, in addition to investors who are the intended beneficiaries of the rules.

Board member Steven Harris, who served on the Senate Banking Committee staff and helped shape the Sarbanes-Oxley Act, will chair the new advisory group. He said in a statement announcing the formation of the group that it will serve “as a way to better ensure that the views of investors are carefully considered in the work of the PCAOB.” As he was leaving his post as chairman of the PCAOB, Mark Olson said the new panel “will provide an additional opportunity for the Board to hear from investors on a broad range of issues affecting investor protection.”

The Securities and Exchange Commission, which oversees the PCAOB, formed an investor advisory group of its own in early June. The group has identified a number of issues for possible discussion, including disclosures, technology, financial literacy, valuation and several others.

The PCAOB’s charter forming the investor group says the board will look to the group “to provide high-level advice and insight on matters the board and its staff may face in fulfilling its mission to protect investors” under Sarbanes-Oxley. The initial panel is expected to have approximately 15 members, and they generally will be appointed to three-year terms.
