Our operating results and cash flow have fluctuated in the past and may fluctuate significantly in the future as a result of a variety of factors, including purchasing patterns, timing of introductions of new solutions and enhancements by us and our competitors, and fluctuating economic conditions. Because license fees for our software products are substantial and the implementation of our solutions often requires the services of our engineers over an extended period of time, the sales process for our solutions is lengthy and can exceed one year. Accordingly, software revenues are difficult to predict, and the delay of any order could cause our quarterly revenues to fall substantially below expectations. Moreover, to the extent that we succeed in shifting customer purchases away from point solutions and toward integrated solutions, the likelihood of delays in ordering may increase and the effect of any delay may become more pronounced. We ship software products within a short period after receipt of an order and usually do not have a material backlog of unfilled orders of software products. Consequently, revenues from software licenses, including license renewals, in any quarter are substantially dependent on orders booked and shipped in that quarter. Historically, a majority of each quarter's revenues from software licenses has been derived from license agreements that have been consummated in the final weeks of the quarter. Therefore, even a short delay in the consummation of an agreement may cause revenues to fall below expectations for that quarter. Since our expense levels are based in part on anticipated revenues, we may be unable to adjust spending in a timely manner to compensate for any revenue shortfall and any revenue shortfall would likely have a disproportionately adverse effect on net income. We expect that these factors will continue to affect our operating results for the foreseeable future.
