Acquisition-Related Revenue and Cost of Revenue.The Company provides supplementary non-GAAP financial measures of revenue, which include revenue related to acquisitions, primarily from Swype and Equitrac for the three months ended September 30, 2012, and primarily from Equitrac, Loquendo, eCopy and Swype for the twelve months ended September 30, 2012, that would otherwise have been recognized but for the purchase accounting treatment of these transactions. Non-GAAP revenue also includes revenue that the Company would have otherwise recognized had the Company not acquired intellectual property and other assets from the same customer. Because GAAP accounting requires the elimination of this revenue, GAAP results alone do not fully capture all of the Company’s economic activities. These non-GAAP adjustments are intended to reflect the full amount of such revenue. The Company includes non-GAAP revenue and cost of revenue to allow for more complete comparisons to the financial results of historical operations, forward-looking guidance and the financial results of peer companies. The Company believes these adjustments are useful to management and investors as a measure of the ongoing performance of the business because, although we cannot be certain that customers will renew their contracts, the Company historically has experienced high renewal rates on maintenance and support agreements and other customer contracts. Additionally, although acquisition-related revenue adjustments are non-recurring with respect to past acquisitions, the Company generally will incur these adjustments in connection with any future acquisitions. Acquisition-Related Costs, Net. In recent years, the Company has completed a number of acquisitions, which result in operating expenses which would not otherwise have been incurred. The Company provides supplementary non-GAAP financial measures, which exclude certain transition, integration and other acquisition-related expense items resulting from acquisitions, to allow more accurate comparisons of the financial results to historical operations, forward-looking guidance and the financial results of less acquisitive peer companies. The Company considers these types of costs and adjustments, to a great extent, to be unpredictable and dependent on a significant number of factors that are outside of the control of the Company. Furthermore, the Company does not consider these acquisition-related costs and adjustments to be related to the organic continuing operations of the acquired businesses and are generally not relevant to assessing or estimating the long-term performance of the acquired assets. In addition, the size, complexity and/or volume of past acquisitions, which often drives the magnitude of acquisition-related costs, may not be indicative of the size, complexity and/or volume of future acquisitions. By excluding acquisition-related costs and adjustments from our non-GAAP measures, management is better able to evaluate the Company's ability to utilize its existing assets and estimate the long-term value that acquired assets will generate for the Company. The Company believes that providing a supplemental non-GAAP measure which excludes these items allows management and investors to consider the ongoing operations of the business both with, and without, such expenses.
