Use of Non-GAAP Financial Measures

In addition to financial measures prepared in accordance with generally accepted accounting principles (GAAP), this earnings announcement also contains non-GAAP financial measures. The reasons that we use these measures, a reconciliation of these measures to the most directly comparable GAAP measures, and other information relating to these measures are included below following our GAAP financial statements.

Factors Affecting Future Performance

This press release contains "forward-looking" statements within the meaning of the Private Securities Litigation Reform Act of 1995, including, but not limited to, statements relating to estimates and projections of future earnings per share, cash flow and revenue growth and other financial results, developments relating to our customers and end-markets, and plans concerning business development opportunities and divestitures. Words such as "believes," "intends," "anticipates," "plans," "expects," "projects," "forecasts," "will" and similar expressions, and references to guidance, are intended to identify forward-looking statements. Such statements are based on management's current assumptions and expectations and no assurances can be given that our assumptions or expectations will prove to be correct. A number of important risk factors could cause actual results to differ materially from the results described, implied or projected in any forward-looking statements. These factors include, without limitation: (1) markets into which we sell our products declining or not growing as anticipated; (2) fluctuations in the global economic and political environments; (3) our failure to introduce new products in a timely manner; (4) our ability to execute acquisitions and license technologies, or to successfully integrate acquired businesses and licensed technologies into our existing business or to make them profitable, or successfully divest businesses; (5) our failure to adequately protect our intellectual property; (6) the loss of any of our licenses or licensed rights; (7) our ability to compete effectively; (8) fluctuation in our quarterly operating results and our ability to adjust our operations to address unexpected changes; (9) significant disruption in third-party package delivery and import/export services or significant increases in prices for those services; (10) disruptions in the supply of raw materials and supplies; (11) the manufacture and sale of products exposing us to product liability claims; (12) our failure to maintain compliance with applicable government regulations; (13) regulatory changes; (14) our failure to comply with healthcare industry regulations; (15) economic, political and other risks associated with foreign operations; (16) our ability to retain key personnel; (17) significant disruption in our information technology systems; (18) our ability to obtain future financing; (19) restrictions in our credit agreements; (20) our ability to realize the full value of our intangible assets; (21) significant fluctuations in our stock price; (22) reduction or elimination of dividends on our common stock; and (23) other factors which we describe under the caption "Risk Factors" in our most recent annual report on Form 10-K and in our other filings with the Securities and Exchange Commission. We disclaim any intention or obligation to update any forward-looking statements as a result of developments occurring after the date of this press release.

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 adjustments for mark-to-market accounting and curtailments on post-retirement benefits, 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 “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 and curtailments 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 and Adjusted Operating Profit 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, adjustments for mark-to-market accounting and curtailments on post-retirement benefits, and restructuring and lease charges, and including estimated revenue from contracts acquired in various acquisitions that will not be fully recognized due to business combination accounting rules. Adjusted operating income is calculated by subtracting adjusted R&D expense and adjusted SG&A expense from adjusted gross margin. We use the related term “adjusted operating profit percentage,” or “adjusted operating profit 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 lease 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, adjustments for mark-to-market accounting and curtailments on post-retirement benefits, and restructuring and lease charges, and including estimated revenue from contracts acquired in various acquisitions that will not be fully recognized due to business combination accounting rules. Adjusted earnings per share is calculated by subtracting the items above included in adjusted gross margin, adjusted R&D expense, adjusted SG&A expense, and restructuring and lease charges, and provision for taxes related to these items, 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 and curtailments on post-retirement benefits, and restructuring and lease charges, 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 an expense of $0.00 in 2012 and an expense of $0.01 in 2011, (ii) amortization of intangible assets was an expense of $0.07 in 2012 and an expense of $0.05 in 2011, (iii) inventory fair value adjustments related to business acquisitions was an expense of $0.01 in 2012 and an expense of $0.00 in 2011, (iv) other costs related to business was an expense of $0.00 in 2012 and an expense of $0.01 in 2011, (v) restructuring and lease charges was an expense of $0.02 in 2012 and an expense of $0.00 in 2011, and (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 $0.02 in 2012 and an expense of $0.00 in 2011. The first quarter tax effect on adjusted EPS for each of the remaining items (changes to the fair values assigned to contingent consideration and adjustments for mark-to-market accounting and curtailments on post-retirement benefits) was $0.00 for both 2012 and 2011. 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 and curtailments on post-retirement benefits, restructuring and lease charges, 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.

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.
