Discussion of Non-GAAP Financial Measures

In addition to information regarding the Company's results as determined in accordance with generally accepted accounting principles in the United States ("GAAP"), the Company has provided in this release non-GAAP financial measures, including non-GAAP gross profit as a percentage of revenue, non-GAAP operating income, non-GAAP operating expenses, non-GAAP net income, non-GAAP diluted earnings per share and non-GAAP operating margin as a percentage of revenue, which exclude amortization of intangibles, merger and acquisition-related expenses and benefits, litigation expenses and benefits and other restructuring costs. Non-GAAP gross margin as a percentage of revenue, non-GAAP operating income, non-GAAP operating expenses, non-GAAP net income, non-GAAP diluted earnings per share and non-GAAP operating margin as a percentage of revenue can also exclude certain other gains and losses that are either isolated or cannot be expected to occur again with any predictability or otherwise are not representative of our ongoing operations, tax provisions/benefits related to the previous items, and significant discrete tax events. We exclude the above items because they are outside of our normal operations and/or, in certain cases, are difficult to forecast accurately for future periods.

We utilize several different financial measures, both GAAP and non-GAAP, in analyzing and assessing the overall performance of our business, in making operating decisions, forecasting and planning for future periods, and determining payments under compensation programs. We consider the use of the non-GAAP measures to be helpful in assessing the performance of the ongoing operations of our business. We believe that disclosing non-GAAP financial measures provides useful supplemental data that, while not a substitute for financial measures prepared in accordance with GAAP, allows for greater transparency in the review of our financial and operational performance. We also believe that disclosing non-GAAP financial measures provides useful information to investors and others in understanding and evaluating our operating results and future prospects in the same manner as management and in comparing financial results across accounting periods and to those of peer companies. More specifically, management adjusts for the excluded items for the following reasons:

Amortization of intangibles: we do not acquire businesses and assets on a predictable cycle. The amount of purchase price allocated to the purchased intangible assets and the term of amortization can vary significantly and are unique to each acquisition or purchase. We believe that excluding amortization of purchased intangible assets allows the users of our financial statements to better review and understand the historic and current results of our operations and also facilitates comparisons to peer companies.

Merger or acquisition related expenses and benefits: we incur expenses or benefits with respect to certain items associated with our mergers and acquisitions, such as transaction and integration costs, change in control payments, adjustments to the fair value of assets, etc. We exclude such expenses or benefits as they are related to acquisitions and have no direct correlation to the operation of our ongoing business.

Restructuring and other: we incur restructuring and impairment charges on individual or groups of employed assets, such as inventory or plant, property & equipment, which arise from unforeseen circumstances and/or often occur outside of the ordinary course of our ongoing business. Although these events are reflected in our GAAP financials, these transactions may limit the comparability of our ongoing operations with prior and future periods.

Litigation expenses and benefits: we may incur charges or benefits as well as legal costs in connection with litigation and other contingencies unrelated to our core operations. We exclude these charges or benefits, when significant, as well as legal costs associated with significant legal matters, because we do not believe they are reflective of ongoing business and operating results.

Income tax expense: we estimate the tax effect of the items identified to determine a non-GAAP annual effective tax rate applied to the pretax amount to calculate the non-GAAP provision for income taxes. We also adjust for items for which the nature and/or tax jurisdiction requires the application of a specific tax rate or treatment.

From time to time in the future, there may be other items excluded if we believe that doing so is consistent with the goal of providing useful information to investors and management.

There are limitations in using non-GAAP financial measures because the non-GAAP financial measures are not prepared in accordance with GAAP and may be different from non-GAAP financial measures used by other companies. The non-GAAP financial measures are limited in value because they exclude certain items that may have a material impact on our reported financial results. The presentation of this additional information is not meant to be considered in isolation or as a substitute for the directly comparable financial measures prepared in accordance with GAAP. Investors should review the reconciliation of the non-GAAP financial measures to their most directly comparable GAAP financial measures as provided in the tables accompanying this press release.
