Erica Williams, the departing leader of the Public Company Accounting Oversight Board, urged regulators to still provide adequate resources to the auditing watchdog after her resignation at the request of the Securities and Exchange Commission chairman. 

“My biggest concern is that people pull back from the PCAOB’s mission and not provide the staff with the resources that they need to continue to deliver for investors,” Williams said in an interview Thursday. She added that is a particular concern now given that fraud risk is heightened when the economy tightens.
