Adjusted Revenue and Adjusted Revenue Growth

We use the term “adjusted revenue” to refer to GAAP revenue, including estimated revenue from contracts acquired in various acquisitions that will not be fully recognized due to business combination accounting rules. We use the related term “adjusted revenue growth” to refer to the measure of comparing current period adjusted revenue with the corresponding period of the prior year. We believe that these non-GAAP measures, when taken together with our GAAP financial measures, allow us and our investors to better measure the performance of our investments in technology, to evaluate long-term performance trends and to assess our ability to invest in our business. Adjusted revenue growth also provides for easier comparisons of our performance with prior and future periods and relative comparisons to our peers. Our GAAP revenue for the periods subsequent to our acquisitions does not reflect the full amount of revenue on such contracts that would have otherwise been recorded by the acquired businesses. The non-GAAP adjustment is intended to reflect the full amount of such revenue. We believe our investors will use this adjustment as a measure of the ongoing performance of the acquired businesses because customers have historically entered into such contracts for renewed and/or developmental support, although there can be no assurance that customers will do so in the future.

Organic Revenue and Organic Revenue Growth

We use the term “organic revenue” to refer to GAAP revenue, excluding the effect of foreign currency translation and acquisitions, and including estimated revenue from contracts acquired in various acquisitions that will not be fully recognized due to business combination accounting rules. We use the related term “organic revenue growth” to refer to the measure of comparing current period organic revenue with the corresponding period of the prior year. We believe that these non-GAAP measures, when taken together with our GAAP financial measures, allow us and our investors to better measure the performance of our investments in technology, to evaluate long-term performance trends and to assess our ability to invest in our business. Organic revenue growth also provides for easier comparisons of our performance with prior and future periods and relative comparisons to our peers. We exclude the effect of foreign currency translation from these measures because foreign currency translation is subject to volatility and can obscure underlying trends. We exclude the effect of acquisitions because acquisition activity can vary dramatically between reporting periods and between us and our peers, which we believe makes comparisons of long-term performance trends difficult for management and investors, and could result in overstating or understating to our investors the performance of our operations. We include estimated revenue from contracts acquired with various acquisitions that will not be fully recognized due to business combination rules. Our GAAP revenue for the periods subsequent to our acquisitions does not reflect the full amount of revenue on such contracts that would have otherwise been recorded by the acquired businesses. The non-GAAP adjustment is intended to reflect the full amount of such revenue. We believe our investors will use this adjustment as a measure of the ongoing performance of the acquired businesses because customers have historically entered into such contracts for renewed and/or developmental support, although there can be no assurance that customers will do so in the future.

Adjusted Gross Margin and Adjusted Gross Margin Percentage

We use the term “adjusted gross margin” to refer to GAAP gross margin, excluding amortization of intangible assets, inventory fair value adjustments related to business acquisitions, and including estimated revenue from contracts acquired in various acquisitions that will not be fully recognized due to business combination accounting rules. We also exclude adjustments for mark-to-market accounting on post-retirement benefits, therefore only our projected costs have been used to calculate our non-GAAP measure. We use the related term “adjusted gross margin percentage” to refer to adjusted gross margin as a percentage of adjusted revenue. We believe that these non-GAAP measures, when taken together with our GAAP financial measures, allow us and our investors to better measure the performance of our investments in technology, to evaluate the long-term profitability trends and to assess our ability to invest in our business. We exclude amortization of intangible assets from these measures because intangibles amortization charges do not represent what we believe our investors consider to be costs of producing our products and could distort the additional value generated over the cost of producing those products. In addition, inventory fair value adjustments related to business acquisitions and adjustments for mark-to-market accounting on post-retirement benefits do not represent what we believe our investors consider to be costs used in producing our products. We include estimated revenue from contracts acquired with various acquisitions that will not be fully recognized due to business combination rules. Our GAAP revenue for the periods subsequent to our acquisitions does not reflect the full amount of revenue on such contracts that would have otherwise been recorded by the acquired businesses. The non-GAAP adjustment is intended to reflect the full amount of such revenue. We believe our investors will use this adjustment as a measure of the ongoing performance of the acquired businesses because customers have historically entered into such contracts for renewed and/or developmental support, although there can be no assurance that customers will do so in the future.

Adjusted Selling, General and Administrative (“SG&A”) Expense and Adjusted SG&A Percentage

We use the term “adjusted SG&A expense” to refer to GAAP SG&A expense, excluding amortization of intangible assets, changes to the fair values assigned to contingent consideration, and other costs related to business acquisitions. We use the related term “adjusted SG&A percentage” to refer to adjusted SG&A expense as a percentage of adjusted revenue. We believe that these non-GAAP measures, when taken together with our GAAP financial measures, allow us and our investors to better measure the cost of the internal operating structure, our ability to leverage that structure and the level of investment required to grow our business. We exclude amortization of intangible assets from these measures because intangibles amortization charges do not represent what we believe our investors consider to be costs that support our internal operating structure and could distort the efficiencies of that structure. We exclude changes to the fair values assigned to contingent consideration, and other costs related to business acquisitions, because they only occur due to an acquisition and the potential subsequent repositioning of the business that could distort the performance measures of costs to support our internal operating structure.

Adjusted Research and Development (“R&D”) Expense and Adjusted R&D Percentage

We use the term “adjusted R&D expense” to refer to GAAP R&D expense, excluding amortization of intangible assets. We use the related term “adjusted R&D percentage” to refer to adjusted R&D expense as a percentage of adjusted revenue. We believe that these non-GAAP measures, when taken together with our GAAP financial measures, allow us and our investors to better understand and evaluate our internal technology investments. We exclude amortization of intangible assets from these measures because intangibles amortization charges do not represent what we believe our investors consider to be internal investments in R&D activities and could distort our R&D investment level.

Adjusted Operating Income, Adjusted Operating Profit Percentage, Adjusted Operating Profit Margin and Adjusted Operating Margin

We use the term “adjusted operating income,” to refer to GAAP operating income, excluding amortization of intangible assets, inventory fair value adjustments related to business acquisitions, changes to the fair values assigned to contingent consideration, other costs related to business acquisitions, and restructuring and contract termination charges, and including estimated revenue from contracts acquired in various acquisitions that will not be fully recognized due to business combination accounting rules. We also exclude adjustments for mark-to-market accounting on post-retirement benefits, therefore only our projected costs have been used to calculate our non-GAAP measure. Adjusted operating income is calculated by subtracting adjusted R&D expense and adjusted SG&A expense from adjusted gross margin. We use the related terms “adjusted operating profit percentage,” “adjusted operating profit margin,” or “adjusted operating margin” to refer to adjusted operating income as a percentage of adjusted revenue. We believe that these non-GAAP measures, when taken together with our GAAP financial measures, allow us and our investors to analyze the costs of the different components of producing and selling our products, to better measure the performance of our internal investments in technology and to evaluate the long-term profitability trends of our core operations. Adjusted operating income also provides for easier comparisons of our performance and profitability with prior and future periods and relative comparisons to our peers. We believe our investors do not consider the items that we exclude from adjusted operating income to be costs of producing our products, investments in technology and production or costs to support our internal operating structure, and so we present this non-GAAP measure to avoid overstating or understating to our investors the performance of our operations. We exclude restructuring and contract termination charges because they tend to occur due to an acquisition, divestiture, repositioning of the business or other unusual event that could distort the performance measures of our internal investments and costs to support our internal operating structure. We include estimated revenue from contracts acquired with various acquisitions that will not be fully recognized due to business combination rules. Our GAAP revenue for the periods subsequent to our acquisitions does not reflect the full amount of revenue on such contracts that would have otherwise been recorded by the acquired businesses. The non-GAAP adjustment is intended to reflect the full amount of such revenue. We believe our investors will use this adjustment as a measure of the ongoing performance of the acquired businesses because customers have historically entered into such contracts for renewed and/or developmental support, although there can be no assurance that customers will do so in the future.

Adjusted Earnings Per Share

We use the term “adjusted earnings per share,” or “adjusted EPS,” to refer to GAAP earnings per share, excluding discontinued operations, amortization of intangible assets, inventory fair value adjustments related to business acquisitions, changes to the fair values assigned to contingent consideration, other costs related to business acquisitions, restructuring and contract termination charges, and significant tax credits, and including estimated revenue from contracts acquired in various acquisitions that will not be fully recognized due to business combination accounting rules. We also exclude adjustments for mark-to-market accounting on post-retirement benefits, therefore only our projected costs have been used to calculate our non-GAAP measure. Adjusted earnings per share is calculated by subtracting the items above included in adjusted gross margin, adjusted R&D expense, adjusted SG&A expense, restructuring and contract termination charges, the provision for taxes related to these items, and significant tax credits from GAAP earnings per share. We believe that this non-GAAP measure, when taken together with our GAAP financial measures, allows us and our investors to analyze the costs of producing and selling our products and the performance of our internal investments in technology and our internal operating structure, to evaluate the long-term profitability trends of our core operations and to calculate the underlying value of the core business on a dilutive share basis, which is a key measure of the value of the Company used by our management and we believe used by investors as well. Adjusted earnings per share also facilitates the overall analysis of the value of the Company and the core measure of the success of our operating business model as compared to prior and future periods and relative comparisons to our peers. We exclude discontinued operations, amortization of intangible assets, inventory fair value adjustments related to business acquisitions, changes to the fair values assigned to contingent consideration, other costs related to business acquisitions, adjustments for mark-to-market accounting on post-retirement benefits, restructuring and contract termination charges, and significant tax credits, as these items do not represent what we believe our investors consider to be costs of producing our products, investments in technology and production, and costs to support our internal operating structure, which could result in overstating or understating to our investors the performance of our operations. We include estimated revenue from contracts acquired with various acquisitions that will not be fully recognized due to business combination rules. Our GAAP revenue for the periods subsequent to our acquisitions does not reflect the full amount of revenue on such contracts that would have otherwise been recorded by the acquired businesses. The non-GAAP adjustment is intended to reflect the full amount of such revenue. We believe our investors will use this adjustment as a measure of the ongoing performance of the acquired businesses because customers have historically entered into such contracts for renewed and/or developmental support, although there can be no assurance that customers will do so in the future.

The first quarter tax effect on adjusted EPS for (i) discontinued operations was a benefit of $0.00 in 2013 and an expense of $0.00 in 2012, (ii) amortization of intangible assets was an expense of $0.07 in both 2013 and 2012, (iii) inventory fair value adjustments related to business acquisitions was an expense of $0.00 in 2013 and an expense of $0.01 in 2012, (iv) restructuring and contract termination charges was an expense of $0.01 in 2013 and an expense of $0.02 in 2012, (v) significant tax credits was a benefit of $0.08 in 2013, (vi) the estimated revenue from contracts acquired with various acquisitions that will not be fully recognized due to business combination accounting rules was an expense of $0.01 in 2013 and an expense of $0.02 in 2012. The first quarter tax effect on adjusted EPS for each of the remaining items (changes to the fair values assigned to contingent consideration, other costs related to business acquisitions, and adjustments for mark-to-market accounting on post-retirement benefits) was $0.00 in both 2013 and 2012.

The tax effect for discontinued operations is calculated based on the authoritative guidance in the Financial Accounting Standards Board’s Accounting Standards Codification 740, Income Taxes. The tax effect for amortization of intangible assets, inventory fair value adjustments related to business acquisitions, changes to the fair values assigned to contingent consideration, other costs related to business acquisitions, adjustments for mark-to-market accounting on post-retirement benefits, restructuring and contract termination charges, and significant tax credits, and the estimated revenue from contracts acquired with various acquisitions is calculated based on operational results and applicable jurisdictional law, which contemplates tax rates currently in effect to determine our tax provision.

Adjusted Operating Cash Flow

We use the term “adjusted operating cash flow” to refer to GAAP operating cash flow from continuing operations, excluding the effect of the excess tax benefit from the exercise of equity grants, significant contributions to our post-retirement benefit plans, and significant prepaid royalty payments. We believe that this non-GAAP measure, when taken together with our GAAP financial measure, allows us and our investors to better evaluate the long-term performance trends and to assess our ability to invest in the business. Adjusted operating cash flow also provides for easier comparisons of our performance with prior and future periods and relative comparisons to our peers. We exclude the effect of the excess tax benefit from the exercise of equity grants, significant contributions to our post-retirement benefit plans, and significant prepaid royalty payments from this measure because the excess tax benefit from the exercise of equity grants, significant contributions to our post-retirement benefit plans, and significant prepaid royalty payments can vary dramatically by quarter and between us and our peers and can obscure underlying trends, which we believe makes comparisons of long-term performance trends difficult for management and investors, and could result in overstating or understating to our investors the performance of our operations.

# # #

The non-GAAP financial measures described above are not meant to be considered superior to, or a substitute for, our financial statements prepared in accordance with GAAP. There are material limitations associated with non-GAAP financial measures because they exclude charges that have an effect on our reported results and, therefore, should not be relied upon as the sole financial measures to evaluate our financial results. Management compensates and believes that investors should compensate for these limitations by viewing the non-GAAP financial measures in conjunction with the GAAP financial measures. In addition, the non-GAAP financial measures included in this earnings announcement may be different from, and therefore may not be comparable to, similar measures used by other companies.

Each of the non-GAAP financial measures listed above are also used by our management to evaluate our operating performance, communicate our financial results to our Board of Directors, benchmark our results against our historical performance and the performance of our peers, evaluate investment opportunities including acquisitions and discontinued operations, and determine the bonus payments for senior management and employees.
