PricewaterhouseCoopers (PwC) is considering cutting up to half of its financial services auditing workforce in China as a regulatory probe and customer departure sour the company’s outlook.

The action comes after PwC was investigated by Chinese regulators for its work as the auditor of the financially distressed China Evergrande Group, which opened new tabs, causing several clients to leave.

The company employs at least 2,000 individuals throughout mainland China, with its primary bases in Beijing and Shanghai. PwC is also considering laying off around 20% of personnel in other auditing teams and non-auditing business lines.
