characteristics of all infrastructure and application elements associated with service delivery . this product is based on our unique asi technology , which provides real-time performance analytics and operational intelligence . our key objectives have been to continue to gain market share in the wireless service provider market and to accelerate our enterprise growth by extending into the application performance management segment . a common component of both initiatives has been the acceptance of our unified services delivery management strategy . this strategy has been bolstered by our acquisitions and integration of both voice/video and packet flow or monitoring switch technology . during the first quarter of our fiscal year 2014 , management performed a review of its summation of revenue by industry . as a result , we changed our method of apportioning revenue to our revenue sectors , and the categorization of certain customers to different sectors . this change in the manner of describing fluctuations by sector will not affect our total net revenues , total product and service revenues , or revenue by geography . results overview we saw continued growth during the

intangible assets , share-based compensation , restructuring , certain expenses relating to acquisitions including compensation for post-combination services and business development charges , net of related income tax effects . non-gaap diluted net income per share also excludes these expenses as well as the related impact of all these adjustments on the provision for income taxes . these

future by providing a higher degree of transparency for certain financial measures and providing a level of disclosure that helps investors understand how we plan and measure our business . we believe that providing these non-gaap measures affords investors a view of our operating results that may be more easily compared to our peer companies and also enables investors to consider our operating results on both a gaap and non-gaap basis during and following the integration period of our acquisitions . presenting the gaap measures on their own may not be indicative of our core operating
