SciClone Pharmaceuticals, Inc. Announces Transition From Pricewaterhousecoopers LLP To Pricewaterhousecoopers Zhong Tian LLP As Independent Registered Public Accounting Firm

FOSTER CITY, CA--(Marketwired - January 24, 2014) - SciClone Pharmaceuticals, Inc. (NASDAQ: SCLN) today announced that the Audit Committee of the Company’s Board of Directors has appointed PricewaterhouseCoopers Zhong Tian LLP (“PwC China”) to replace PricewaterhouseCoopers LLP (“PwC US”) as the Company’s independent registered public accounting firm, effective January 24, 2014. The transition of the audit engagement from PwC US to PwC China was based on the determination that PwC China is the principal auditor under applicable auditing standards and on a variety of quantitative and qualitative factors related to the business, including the geographic location of assets, revenues and operations of the Company.

SciClone is pleased that the transition from PwC US to PwC China is taking place smoothly, and with the full cooperation of all parties involved. The Company further noted that there were no disagreements between the Company and PwC US. “We are pleased to work with PwC China as our Company’s independent auditor, and to build on the cooperative relationship we have established with PwC US since April of 2013,” said Wilson W. Cheung, SciClone’s Chief Financial Officer. “We believe that the PwC China team’s deep knowledge and experience within the China pharmaceuticals market, and strong track record of working effectively with companies in the US and China, will serve as excellent resources for SciClone as we continue efforts to grow our business, and as we continue to implement high quality compliance programs throughout our organization. We look forward to further deepening our productive working relationship with PwC China.”

The Company has been advised that the recently announced judicial order to impose a temporary ban on the practice by certain China based audit firms, including PwC China, is not formally in effect and is subject to further review and appeal. Based upon information available to the Company, this procedure is not expected to prevent PwC China from completing the Company’s audit for fiscal year 2013. The Company will continue to monitor the developments regarding this and evaluate this matter to determine if further action is required.

As in the last several years, SciClone will continue to also work with another global, Big Four firm regarding non-audit work, such as internal controls and tax advisory matters in the US, China and other parts of the world where the Company has operations.
