Shares of Subaye, a Nasdaq-listed mainland cloud-computing company, plunged 6 per cent after it announced that PricewaterhouseCoopers Hong Kong had resigned as its independent registered public accounting firm.
PwC Hong Kong's departure followed that of James Crane, Subaye's chief financial officer, who cut ties with the company last month after serving as CFO since October 2007.
Subaye's shares closed down 6.14 per cent at US$2.14 on Thursday.
The company said yesterday that trading had been halted.
The shares have lost 78 per cent so far this year.
In a statement to the US Securities and Exchange Commission (SEC), Subaye said PwC informed it on April 1 that it was resigning because it was unable to verify the cash going into Subaye's business. It said the auditor had also said it could not obtain documents to prove Subaye's subscribers were real.
