Amkor Announces Final Award in Tessera Arbitration

Amkor Technology, Inc. (NASDAQ: AMKR) today announced that the Arbitration Panel from the International Chamber of Commerce has issued the final award in the arbitration proceedings relating to Amkor’s license agreement with Tessera, Inc.

The Panel awarded Tessera $61 million in damages for past royalties due under the license agreement. The award is for the period March 2, 2002 through December 1, 2008 and includes an aggregate of $2 million for the first two months of the fourth quarter of 2008. The Company has already accrued $50 million for unpaid royalties through September 2008 and expects to accrue an additional $12 million for unpaid royalties in the fourth quarter ($9 million for unpaid royalties through September 30, 2008 and $3 million for royalties for the full fourth quarter of 2008). The Panel also found that Tessera is entitled to 3% simple interest for unpaid royalties calculated for the periods set by the final award. Payment of the final award, plus interest, is due in February 2009.

"We are satisfied with the overall results of the arbitration and are moving ahead as a Tessera licensee,” said James Kim, chief executive officer of Amkor. "Our cash position remains solid and we do not expect our ongoing business to be materially affected by the decision.”
