Included in the net loss for the quarter ended June 30, 2002 was an impairment of technology license charge of $8,100,000. Commented Mr. Dale, "We continue to be encouraged by our progress in rebuilding and expanding our sales and marketing organization. At the end of second quarter, despite having less than half our planned sales and marketing team trained and in place, we were able to generate significant revenue growth in both our International and North American markets. Specific to North America, revenue increased 23% over first quarter of 2003, and 38% versus second quarter 2002. Looking forward, we feel confident that ATS will be able to grow 2003 total revenue by 25% versus 2002. In North America, we believe we can grow revenue by at least 60% versus 2002, based on current productivity trends. For the quarter ended June 2003, our cash position essentially remained unchanged at $9.5 million. Given the very positive reception our initial hires have received within the marketplace, we have decided to expand our originally planned number of territories for 2003. We aim to complete this additional hiring and training process by end of fourth quarter. In summary, as a company we could not be more excited by our future prospects to establish the ATS Open Pivot(R) heart valve as the standard of care for mechanical heart valves."
