Bangalore: Software major Infosys today (Oct 28, 2004) said it has sought to delist its American Depository Shares (ADSs) from certain stock exchanges in Germany after it found its stocks traded unauthorisedly in several regional bourses.

"The company recently learnt of the unauthorised listing of its ADSs in Germany on the Berlin-Bremen, Dusseldorf, Munich, Frankfurt, Stuttgart and Xetra exchanges," the NASDAQ listed Infosys said in a statement in Bangalore.

The stocks of Bangalore-based Infosys were being traded under the ticker symbols: IOY.BER, IOY.DUS, IOY.MUN, IOY.FSE, IOY.STU and IOY.ETR respectively.

"These listings occurred without the company's knowledge or permission," it said.

Infosys, traded on the Bombay Stock Exchange (BSE) and the National Stock Exchange (NSE) is the first Indian firm to get listed on the American NASDAQ stock exchange.

Infosys said it has requested the exchanges involved and the stock specialist responsible for the unauthorised listing to de-list Infosys ADS's immediately and halt their trading from these exchanges.

The statement did not specify whether any damages were being claimed from these exchanges.

"The company is aware that unauthorised listing and trading on several German exchanges, has recently commenced in numerous NASDAQ listed stocks," it said.
