This case involves a plaintiff private equity fund that owned zero coupon bonds convertible into the common stock issued by an entertainment company. The private equity fund converted its bonds and received fewer shares of common stock on conversion than it believed it was entitled to under the applicable conversion formula. An expert in trading on the Hong Kong Stock Exchange was sought to discuss the plaintiff’s ability to purchase the several million additional shares it believes it should have received in a fairly short time frame following the conversion given the level of liquidity of entertainment company’s common stock. The expert was also asked to determine what impact such an acquisition program would have had on the trading price of entertainment company’s shares. If it had been negotiated on either on the Stock Exchange or through privately negotiated transactions.
