       The Company&amp;#8217;s quarterly operating results normally
       fluctuate as a result of seasonal variations in its business,
       principally due to the timing of client budget cycles and
       student attendance at client facilities. Historically, the
       Company has had lower new sales in its first and fourth quarters
       than in the remainder of the year. The Company&amp;#8217;s expenses,
       however, do not vary significantly with these changes, and, as a
       result, such expenses do not fluctuate significantly on a
       quarterly basis. Historically, the Company has performed a
       disproportionate amount of its professional services, for which
       revenue is recognized as services are performed, in its second
       and third quarters each year. The Company expects quarterly
       fluctuations in operating results to continue as a result of the
       uneven seasonal demand for its licenses and services offerings.
   &lt;/div&gt;
   &lt;/div&gt;

      <ElementDefenition>This element can be used to disclose the entire quarterly financial data disclosure in the annual financial statements as a single block of text.  The disclosure includes a tabular presentation of financial information for each fiscal quarter for the current and previous year, including revenues, gross profit, income (loss) before extraordinary items and cumulative effect of a change in accounting principle and earnings per share data. It also includes an indication if the information in the note is unaudited, comments on the aggregate effect of year-end adjustments, and an explanation of matters or transactions that affect comparability or are pertinent to an understanding of the information furnished. Alternatively, the details of this disclosure can be reported using the elements in this group, or by using other taxonomy elements and applying the appropriate quarterly date and period contexts when creating an instance document. For example, the element for "Interest and Dividend Income, Operating" may be used by financial institutions from the Statement of Income, applying the appropriate quarterly date and period context when creating an instance document.</ElementDefenition>
