LIME Asset Management Co. is a South Korean investment consulting company that was established on March 30, 2012 and best known for the Korea LIME investment scandal.  The company was founded by Jongjoon Won, who was previously a fund manager at Truston Asset Management and Brain Asset Management.  In 2015 the company shifted to being operated as a hedge fund management firm.  The company quickly developed by a private fund that focused on investment in mezzanine financial products.  It was revealed that Vice-President Jongpil Lee of the company embezzled funds from companies where customer assets had been invested. The case was investigated at the Criminal Affairs Department 6 of the Seoul Southern District Prosecutors' Office.

Issues
In July 2019, LIME began selling convertible bonds of companies listed on the KOSDAQ, and around this time, suspicion arose that the company was maintaining an illegal rate of return. The share prices of stocks that were in the fund run by LIME crashed, and there were concerns of an imminent fund run crises. This led to redemptions being frozen. The issue was caused by purchasing a large volume of insolvent assets, including mezzanine of KOSDAQ zombie companies, for increasing the rate of return in the short-term. In Korea there are regulations which limit how many bonds that can be owned by one entity. However, to bypass this regulation, "parking transactions" were done, by making purchases in the name of another company. It is also alleged that when the fund experienced a loss, returns were fabricated by replacing the loss with monies from another fund.

Problem 
According to the Financial Supervisory Service, Lime Asset Management was found to have sold open funds that can be redeemed at any time while investing in assets with low exchangeability. It also invested more than the principal amount invested in non-current assets, such as private equity bonds, in total revenue swaps (TRS) transactions. Lime Asset Management is known to have signed TRS contracts worth 670 billion won with three securities firms—Shinhan Financial Investment (500 billion won), KB Securities (100 billion won) and Korea Investment & Securities (70 billion won) -- for the three parent funds (Pluto FI D-1, Tetis 2 and Pluto TF 1).

Total revenue swap (TRS) transactions are transactions in which a securities firm purchases assets for a certain fee from an asset manager, and an asset management company has a return from assets, with the return taken by an asset manager but the assets held by a securities firm. From an asset manager's point of view, the company can increase its return as it can enjoy leverage effects. On the other hand, if losses occur on funds run by an operator, securities firms demand an increase in the TRS's collateral ratio, and if they do not, securities firms charge delayed interest, further lowering the fund's yield.

Lime Asset Management operated privately and sold only private equity funds that could be invested in unlisted stocks or mezzanine. The private equity fund was sold using the method invested by the fund to attract many investors.
