The majority of Yin's wealth is derived from Ruentex Group, a closely held company he inherited from his father. The Taipei-based conglomerate operates businesses in textiles, real estate and medical service, with total annual revenue of NT$1.2 trillion ($43 billion) in 2016, according to a rating by China Credit Information Systems.
Ruentex Group owns 91 percent of closely held Nan Shan Life Insurance through holding company Ruen Chen, according to a 2015 Ruentex Development presentation. The insurer is valued using the average price-to-book value multiple of three publicly traded peer companies: China Life Insurance, Fubon Financial Holding and Cathay Financial.
Ruentex Group also has stakes in publicly traded subsidiaries Ruentex Development Co, Ruentex Industries and Ruentex Engineering & Construction, according to stock exchange filings as detailed in the asset notes.
The rest of the group -- Ruentex Other -- is valued using disclosed revenue for 2016 minus the revenue reported for the publicly traded subsidiaries and Nan Shan Life, and the average enterprise value-to-sales, value-to-EBIT and value-to-EBITDA multiples of two peers: Dah Chong Hong Holdings and Daewoo International.
Yin also owns about 6 percent of Sun Art Retail, a hypermarket operator in China, through BVI companies, according to the company's disclosure dated Dec. 7, 2017. He has agreed to sell all his stake to Taobao China Holding, according to an agreement dated Nov. 20, 2017.
