“With the exception of the charges we incurred during the last quarter of the year relating to the upgrade program, 2004 has been a solid year for AMAC,” commented Howard M. Siegel, AMAC’s Chief Executive Officer. “As a result of our strategic acquisitions, adoption and implementation of operational automating software and revenue growth in the TAS segment, we were able to achieve significant increases in operating cash flow.  The year was also capped off with the announcement of McKesson’s selection of AMAC as a coalition partner in the Medicare Chronic Care Improvement Program.  The program is expected to include disease management for Mississippi’s Medicare fee-for-service beneficiaries with heart failure and diabetes and McKesson intends to utilize AMAC’s telehealth services for remote patient monitoring.” Siegel concluded, “We plan to continue to execute our business strategy of maintaining a diversified revenue stream as we forge ahead with the provision of remote home based monitoring and healthcare communication and solution services.”
