PwC Australia exited eight partners, including its former chief risk and reputation officer, following an investigation into the sharing of confidential government tax policy information at the firm.

Sean Gregory was removed for his failure to exercise “expected leadership or governance responsibilities to prevent these actions or to address the deficiencies in culture at the firm or hold others accountable for their behaviors,” PwC Australia said in a press release Monday. In total, the firm has named 12 individuals disciplined for their roles in the scandal, including former Chief Executive Tom Seymour.
