FACTBOX - The assets of Thailand's ex-first family, the Thaksins

(Reuters) - A Thai court found Potjaman Shinawatra, the wife of ousted prime minister Thaksin Shinawatra and a major force in his political and business empire, guilty of tax fraud on Thursday and sentenced her to three years in jail.

Potjaman, her brother Bannapot Damapong and her secretary were charged with colluding to evade tax worth 546 million baht (8 million pounds) in the transfer of shares in the Shincorp telecoms firm Thaksin founded.

Since a 2006 coup, about $2 billion (1 billion pounds) of Thaksin's assets have been frozen but he still ranks as Thailand's 16th richest person, worth $400 million, in a 2008 Forbes magazine rich list.

Here are some key facts about the wealth of him and his family.

SHINCORP:

-- Thaksin and Potjaman set up a small computer dealership in 1983. It evolved into Shin Corp, Thailand's largest telecoms group, valued at $2.5 billion on the Thai bourse with interests ranging from mobile phones and satellites to the Internet and media.

-- In January 2006, the Shinawatra and Damapong families sold a controlling 49.6 percent stake in Shin to Singapore state investment firm Temasek Holdings for 73.3 billion baht in cash.

-- The Asset Examination Committee (AEC), set up after Thaksin was ousted in a September 2006 coup to probe allegations of corruption during his five years in office, said it could only trace 52.9 billion baht of the Shin proceeds in bank accounts.

-- The Shin deal unearthed a complex web of share transactions between Thaksin's children and holding companies set up in the British Virgin Islands, a Caribbean tax haven.
