Wilshire Bancorp Announces the Engagement of Crowe Horwath LLP as the Company’s Independent Registered Public Accounting Firm

LOS ANGELES (June 12, 2012) — Wilshire Bancorp, Inc. (NASDAQ: WIBC), the parent company of Wilshire State Bank, announced today that the Audit Committee of the Board of Directors has engaged Crowe Horwath LLP to serve as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2012.  The Audit Committee selected Crowe Horwath after evaluating the services offered by several public accounting firms, including Deloitte & Touche LLP, the Company’s previous independent registered public accounting firm.  The change in independent auditors is not the result of any disagreement between Wilshire Bancorp and Deloitte & Touche LLP.

“As done on a periodic basis, the Audit Committee conducted a thorough auditor evaluation and selection process,” said Alex Ko, Executive Vice President and Chief Financial Officer of Wilshire Bancorp.  “Crowe Horwath is highly regarded for their expertise in financial services, and it was determined that they were best suited to meet our auditing needs.”
