In the early '90s, Lim got involved in a start-up Indonesian palm-oil company, Wilmar. By the second half of the decade, he had written off that investment. The Indonesian economy was weakening from the mid-90s and then the Indonesian currency fell from 2,500 rupiah against the US dollar to 16,000 rupiah. In 2000, Lim restructured his stake in Wilmar with a US$10 million investment. Wilmar did a Reverse Take Over (RTO) in 2006. Businessman Robert Kuok decided to inject his Malaysian palm oil operations into Wilmar in 2007. In response to a 2006 FDA ruling mandating the labeling of trans fatty acids on the Nutrition Facts label, food manufacturers began eliminating trans fats from their products and began substituting them with palm oil. Imports to the United States alone increased by nearly 60%. The increased use of biofuels at the expense of fossil fuels also contributed significantly to demand. In 2010, Lim cashed out for US$1.5 billion.
