A decline in market acceptance for Microsoft technologies on which our products rely could have a material adverse affect on us
Our products currently run on Microsoft Windows operating systems. Our web client interfaces are supported on certain browsers which run on Windows, Mac and Linux. A decline in market acceptance for Microsoft technologies or the increased acceptance of other server technologies could cause us to incur significant development costs and could have a material adverse effect on our ability to market our current products. Although we believe that Microsoft technologies will continue to be widely used by businesses, we cannot assure you that businesses will adopt these technologies as anticipated or will not in the future migrate to other computing technologies that we do not currently support. In addition, our products and technologies must continue to be compatible with new developments in Microsoft technologies. We cannot assure you that we can maintain such compatibility or that we will not incur significant expenses in connection therewith.
