History
Chunghwa Telecom was founded as a company on June 15, 1996, as part of the government's privatization efforts.
Prior to this, it was operated as a business unit of the Directorate General of Telecommunications for over 100 years. The company has a long history, and it's impressive to see how far it's come.
The company's common shares have been listed on the Taiwan Stock Exchange under the number "2412" since October 2000, and its ADSs have been listed on the New York Stock Exchange under the symbol "CHT" since July 2003.

This listing marked a significant milestone for the company, allowing it to expand its reach and attract new investors.
In August 2005, Chunghwa Telecom became a privatized company, as the Taiwan government's ownership was reduced to less than 50%. This move paved the way for the company to operate more independently.
Chunghwa Telecom was once part of a monopoly on the telecommunications market in Taiwan, but the government's "telecommunications liberalization" policy changed that. The policy aimed to make the industry more competitive and improve service quality.
The company was formally established on July 1, 1996, with a capital of NT$96.477 billion yuan, operating first class and second class telecom services.
