Ernst & Young said a history of recurring operating losses and a net capital deficiency "raise substantial doubt about the company's ability to continue as a going concern." Insmed, in the annual report, said that its ability to continue as a going concern depends on its being able to attain additional financing, and ultimately generate positive cash flow and profitability. Since filing the annual report on March 6, Insmed has raised nearly $43 million in cash through the sale of equity. As such, the company believes that the amount of cash it raised -- along with the amount of cash it had on hand before the offering -- will be sufficient to fund operational needs through at least the second quarter of 2007. Shares were off 7 cents to $2. Shares of Laserscope ( LSCP) jumped 11% after the medical device maker received a $7 million order in China for its GreenLight laser systems and fiber optic delivery devices. The order, which will be delivered over the next 12 months, represents the largest ever one-time order for GreenLight products, Laserscope said. "We expect that this order will help us gain a widespread customer base in China, contribute to our revenue growth in 2006 and lead to higher fiber sales and increased profit in 2007 and beyond," Laserscope said. Shares were trading up $2.29 to $23.29.
