36 Explanation of Non-GAAP Financial Measures Allscripts reports its financial results in accordance with generally accepted accounting principles, or GAAP. To supplement this information, Allscripts presents in this presentation non-GAAP revenue and net income, including non-GAAP net income on a per share basis, which are non-GAAP financial measures under Section 101 of Regulation G under the Securities Exchange Act of 1934, as amended. Non-GAAP revenue consists of GAAP revenue and legacy Allscripts revenue for periods prior to the consummation date of the Misys merger and adds back the deferred revenue adjustment booked for GAAP purposes and excludes revenue from prepackaged medications. Non-GAAP net income consists of GAAP net income and includes legacy Allscripts net income for periods prior to the consummation date of the Misys merger, excludes acquisition-related amortization, stock-based compensation expense and transaction-related expenses, adds back the deferred revenue adjustment and excludes net income from prepackaged medications, in each case net of any related tax benefit. Acquisition-Related Amortization. Acquisition-related amortization expense is a non-cash expense arising from the acquisition of intangible assets in connection with acquisitions or investments. Allscripts excludes acquisition-related amortization expense from non-GAAP net income because it believes (i) the amount of such expenses in any specific period may not directly correlate to the underlying performance of Allscripts business operations and (ii) such expenses can vary significantly between periods as a result of new acquisitions and full amortization of previously acquired intangible assets. Management believes that this adjustment facilitates comparisons of the separate pre-merger results of legacy Misys and legacy Allscripts to that of the Company's post-merger results. Investors should note that the use of these intangible assets contributed to revenue in the periods presented and will contribute to future revenue generation and should also note that such expense will recur in future periods. Stock-Based Compensation Expense. Stock-based compensation expense is a non-cash expense arising from the grant of stock awards to employees. Allscripts excludes stock- based compensation expense from non-GAAP net income because it believes (i) the amount of such expenses in any specific period may not directly correlate to the underlying performance of Allscripts business operations and (ii) such expenses can vary significantly between periods as a result of the timing of grants of new stock-based awards, including grants in connection with acquisitions. Investors should note that stock-based compensation is a key incentive offered to employees whose efforts contributed to the operating results in the periods presented and are expected to contribute to operating results in future periods and should also note that such expense will recur in future periods. Deferred Revenue Adjustment. Deferred revenue adjustment reflects the fair value adjustment to deferred revenues acquired in connection with the Misys merger transaction consummated on October 10, 2008. The fair value of deferred revenue represents an amount equivalent to the estimated cost plus an appropriate profit margin, to perform services related to legacy Allscripts software and product support, which assumes a legal obligation to do so, based on the deferred revenue balances as of October 10, 2008. Allscripts adds back this deferred revenue adjustment for non-GAAP revenue and non-GAAP net income because it believes the inclusion of this amount directly correlates to the underlying performance of Allscripts operations and facilitates comparisons of the separate pre-merger results of legacy Misys and legacy Allscripts to that of the Company's post-merger results. Non-GAAP adjustments are effected for tax at the actual as-reported effective tax rate for all fiscal 2009 periods presented. Non-GAAP adjustments are effected for tax at the anticipated full-year effective tax rate for all fiscal 2010 periods presented. Management also believes that non-GAAP revenue and net income provide useful supplemental information to management and investors regarding the underlying performance of the Company's business operations and facilitates comparisons of the separate pre-merger results of legacy Misys and legacy Allscripts to that of the Company's post-merger results. Purchase accounting adjustments made in accordance with GAAP can make it difficult to make meaningful comparisons of the underlying operations of the business without considering the non-GAAP adjustments that we have provided and discussed herein. Management also uses this information internally for forecasting and budgeting as it believes that the measure is indicative of the Company's core operating results. In addition, the Company uses Non-GAAP net income to measure achievement under the Company's cash incentive compensation plans. Note, however, that non-GAAP revenue and net income are performance measures only, and they do not provide any measure of the Company's cash flow or liquidity. Non-GAAP financial measures are not in accordance with, or an alternative for, measures of financial performance prepared in accordance with GAAP and may be different from non-GAAP measures used by other companies. Non-GAAP measures have limitations in that they do not reflect all of the amounts associated with Allscripts' results of operations as determined in accordance with GAAP. Investors and potential investors are encouraged to review the reconciliation of non-GAAP financial measures with GAAP financial measures contained within the attached condensed consolidated financial statements. |
