The \u201cqueen of shell companies\u201d had already been dethroned as Hong Kong\u2019s richest woman. Now Pollyanna Chu Yuet Wah, whose Kingston Financial Group Ltd. operates Macau casinos and margin-lending businesses, has lost 74 percent of her fortune, the biggest destruction of individual wealth this year in Asia, according to the Bloomberg Billionaires Index, a ranking of the world\u2019s 500 richest people. After starting the year at No. 183 with $8.4 billion, she\u2019s currently worth $2.2 billion and has dropped off the list. The decline of her fortune deepened after Kingston reported fiscal 2018 profit of HK$1.4 billion ($178.4 million), a 9 percent drop from a year earlier, as soured margin loans increased. The firm gets most of its financing from unsecured loans provided cheaply by Chu and her family, according to an analysis by activist investor David Webb. Kingston plunged 17 percent on Jan. 30 after the Securities and Futures Commission said that 20 shareholders controlled more than 91 percent of the stock. It slid further in March after FTSE Russell purged Kingston from its benchmarks. Kingston is Chu\u2019s main holding, but her active role in Hong Kong\u2019s market for small-cap stocks earned her the moniker \u201cqueen of shell companies\u201d in the Hong Kong press. Part of Chu\u2019s wealth stems from her father\u2019s background managing VIP rooms in Macau. Gaming in the former Portuguese colony, which accounts for about 15 percent of Kingston\u2019s revenue, generated HK$473.5 million last year, down 3.8 percent from fiscal 2017. Chu, 59, joined a record $5.2 billion deal to buy most of a Hong Kong skyscraper from Li Ka-Shing\u2019s CK Asset Holdings Ltd., in the most expensive real estate transaction ever. CK Asset confirmed in May that the deal was completed.
