Advanced Semiconductor Engineering (ASE) and Siliconware Precision Industries (SPIL) are in talks about the feasibility of forming an industrial holding company, according to separate filings issued by the companies with the Taiwan Stock Exchange (TSE).

The filings were made in response to a recent Chinese-language Liberty Times report saying ASE and SPIL will make a joint announcement later this week about the establishment of a holding company that will apply for Nasdaq listing.

ASE indicated the company has discussed with SPIL and exchanged opinions on the possibility to jointly organize a holding company. "If both parties reach consensus on relevant terms and conditions, and each party's board meeting approves the terms, the company will make relevant announcement in accordance with laws and regulations," ASE said in a company filing with TSE.

SPIL also confirmed that the company and ASE are in talks to form a holding company. The talks are still ongoing and "there can be no assurance that the proposed transaction will be consummated eventually," SPIL said in its filing with TSE.

ASE's shares closed at NT$32.45 (US$1) on the Taiwan Stock Exchange (TSE) on May 24, up NT$1.20 or 3.8%, while SPIL's share price closed at NT$50, up NT$1.20 or 2.5%.
