WNS WNS Holdings Limited

WNS (Holdings) Limited (NYSE: WNS) ("WNS"), a leading provider of global business process outsourcing services, today announced that it has filed an amendment to its Annual Report on Form 20-F for the fiscal year ended March 31, 2010, which was originally filed with the Securities and Exchange Commission on June 15, 2010, for the sole purpose of furnishing the financial statements of this Annual Report in XBRL (eXtensible Business Reporting Language) format. XBRL is a language for the electronic communication of business and financial data, which greatly increases the speed of handling of financial data, reduces the chance of error and permits automatic checking of information.

"As a foreign private issuer, utilizing XBRL is not yet mandatory for us. However, we have voluntarily furnished the financial statements of our Annual Report in XBRL format this year along with other domestic filers in an effort to meet and exceed corporate disclosure standards," stated Alok Misra, WNS's Group CFO.

The XBRL version of the financial statements of the Annual Report on Form 20-F for the fiscal year ended March 31, 2010, is available on WNS's corporate Web site at www.wns.com, in the Investor Relations section.
