Number of Active Network Clients
We define an active network client as an organization that has implemented one of more of solutions but has not implemented either the Conversations or PowerReviews Enterprise platforms. Such solutions may include our Connections solutions, Media solutions or Express platform. We count organizations that are closely related as one client, even if they have signed separate contractual agreements. We believe that our network client base in combination with our enterprise client base is an indicator of the reach of our network.
Non-GAAP Financial Measures
Adjusted EBITDA discussed in this press release is defined as net loss adjusted for stock-based expense, contingent consideration related to acquisition, adjusted depreciation and amortization (which excludes amortization of capitalized internal-use software development costs), integration and other costs related to acquisitions, other non-business costs and benefits, income tax expense and other (income) expense, net. Non-GAAP net loss, which is used to calculate non-GAAP net loss per share, is defined as our GAAP net loss adjusted to exclude stock-based expense, contingent consideration related to acquisition, amortization of acquired intangible assets, integration and other costs related to acquisitions, and other non-business costs and benefits along with the associated income tax effect of these adjustments. Non-GAAP basic and diluted loss per share for the fourth fiscal quarter and fiscal year ended April 30, 2012 has been calculated assuming the conversion of all outstanding shares of our preferred stock into 27,897,031 shares of our common stock as of the first day of the beginning of the period. Management presents these non-GAAP financial measures because it considers them to be important supplemental measures of core operating performance. Management uses the non-GAAP financial measures for planning purposes, including analysis of the company's operating performance against prior periods and the effectiveness of our business strategies, the preparation of operating budgets and to determine appropriate levels of operating and capital investments, as well as and in communications with our board of directors concerning our financial performance. Management also believes that the non-GAAP financial measures provide additional insight for securities analysts and investors in evaluating the company's financial and operational performance without regard to items that can vary substantially from company to company depending upon their financing, capital structures and the method by which assets were acquired. However, these non-GAAP financial measures have limitations as an analytical tool, and you should not consider them in isolation or as a substitute for analysis of our results of operations as reported under GAAP. Furthermore, these non-GAAP financial measures may not be comparable to similarly titled measures of other organizations because other organizations may not calculate these non-GAAP financial measures in the same manner. We intend to provide these non-GAAP financial measures as part of our future financial results discussions and, therefore, the inclusion of these non-GAAP financial measures will provide consistency in our financial reporting. A reconciliation of these non-GAAP measures to GAAP is provided in the accompanying tables.
