generally paid in advance of rendering services either quarterly or in full upon commencement of the subscription period , which is usually for one year and automatically renewed each year . as a result , the timing of our cash flows generally precedes our recognition of revenues and income and our cash flow from operations tends to be higher in the first quarter as we receive subscription payments . examples of these arrangements include subscriptions that allow our customers to access our standardized coverage language , our claims fraud database or our actuarial services throughout the subscription period . in general , we experience minimal revenue seasonality within the business . our long-term agreements are generally for periods of three to five years . we recognize revenue from subscriptions ratably over the term of the subscription and most long-term agreements are recognized ratably over the term of the agreement . certain of our solutions are also paid for by our customers on a transactional basis . for example , we have solutions that allow our customers to access fraud detection tools in the context of an individual mortgage application or loan , obtain

of revenues , and all other personnel , including executive managers , sales people , marketing , business development , finance , legal , human resources , and administrative services , as selling , general and administrative expenses . a significant portion of our other operating costs , such as facilities and communications , are also either captured within cost of revenues or selling , general and administrative expense based on the nature of the work being performed . while we expect to grow our headcount over time to take advantage of our market opportunities , we believe that the economies of scale in our operating model will allow us to grow our personnel expenses at a lower rate than revenues . historically , our ebitda margin has improved because we have been able to increase revenues without a proportionate corresponding increase in expenses . however , part of our corporate strategy is to invest in new solutions which may offset margin expansion . cost of
