2. Forward Looking Statements/Risk Factors This report includes forward-looking statements that are subject to risks and uncertainties that could cause actual results or objectives to differ materially from those projected. We undertake no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise. Such risks and uncertainties include, but are not limited to, risks arising from our providing services exclusively to the health care industry, primarily providers of long-term care; credit and collection risks associated with this industry; one client accounting for approximately 19% of 2006 six month period revenues (the client has completed its previously announced merger on March 14, 2006); our claims experience related to workers compensation and general liability insurance; the effects of changes in, or interpretations of laws and regulations governing the industry, including state and local regulations pertaining to the taxability of our services; and risk factors described in our Form 10-K filed with the Securities and Exchange Commission for the year ended December 31, 2005 in Part I thereof under Government Regulation of Clients, Competition and Service Agreements/Collections and Risk Factors. Many of our clients revenues are highly contingent on Medicare and Medicaid reimbursement funding rates, which have been and continue to be adversely affected by the change in Medicare payments under the 1997 enactment of Medicare Prospective Payment System. That change, and the lack of substantive reimbursement funding rate reform legislation, as well as other trends in the long-term care industry have resulted in certain of our clients filing for bankruptcy protection. Others may follow. Any decisions by the government to discontinue or adversely modify legislation related to reimbursement funding rates will have a material adverse affect on our clients. These factors, in addition to delays in payments from clients, have resulted in and could continue to result in significant additional bad debts in the near future. Additionally, our operating results would also be adversely affected if unexpected increases in the costs of labor and labor related costs, materials, supplies and equipment used in performing our services could not be passed on to clients. In addition, we believe that to improve our financial performance we must continue to obtain service agreements with new clients, provide new services to existing clients, achieve modest price increases on current service agreements with existing clients and maintain internal cost reduction strategies at our various operational levels. Furthermore, we believe that our ability to sustain the internal development of managerial personnel is an important factor impacting future operating results and successfully executing projected growth strategies.
