Advanced Semiconductor Engineering (ASE) has received clearance from anti-trust authorities in South Korea and Germany for its intended buyout of Siliconware Precision Industries (SPIL), according to the semiconductor packaging company.

ASE is in the process of acquiring more SPIL shares which will bring its total ownership interest in the fellow packaging and testing company to 49.71%. The ongoing tender offer will expire on February 16.

ASE said that completion of its latest tender offer for SPIL shares will encourage the company to acquire SPIL's remaining shares.

ASE's previous tender offer for SPIL shares was completed in September 2015, which enabled ASE to obtain a 25% stake in the company.
