The Taiwan Stock Exchange said today that shares in Hon Hai Precision Industry, also known as Foxconn, will be suspended from trade tomorrow due to a "major announcement". 

The stock exchange did not elaborate. 

It said that along with Hon Hai, trading will also be halted in shares of affiliate Foxconn Technology. 

A trading halt is customary for listed companies in Taiwan ahead of announcements which may affect trading. 

Hon Hai has said it is due to hold a regularly scheduled board meeting tomorrow. 

Japan's Sharp and Foxconn are set to sign a merger deal this week after repeated delays.

The two sides are set to agree on a smaller bailout than originally planned for the troubled Japanese electronics maker, two sources familiar with the talks said over the weekend.
