Symantec Settles One IRS Matter for $36 Million

CUPERTINO, Calif. -- Jun 09, 2006 -- Symantec Corp. (NASDAQ: SYMC) today announced that it has reached an agreement in principle with the Internal Revenue Service to settle the outstanding claim concerning the audit of the company's 2003 and 2004 fiscal years. The company expects to settle this outstanding tax obligation for $36 million, excluding interest, compared to the original IRS assessment of approximately $100 million. The company anticipates that it will finalize the settlement with the IRS by the end of June 2006.

On April 17, 2006, Symantec disclosed that the company received notices of proposed adjustment from the IRS in connection with an ongoing audit of Symantec's 2003 and 2004 fiscal years. The IRS claimed that the company owed an incremental tax liability of approximately $100 million, excluding penalties and interest, primarily related to transfer pricing matters between Symantec and a foreign subsidiary.

The company expects that this cash settlement will be reflected on the June quarter balance sheet. In addition, the company's recently filed Form 10-K reflects appropriate accruals to cover the settlement.

Symantec continues to appeal a separate IRS claim also announced on April 17, 2006 concerning the IRS exam of the 2000 and 2001 tax years for Veritas Software Corp., which the company acquired in July 2005.
