Non-GAAP Financial Measures To supplement our financial results presented on a GAAP basis, we use the non-GAAP measure indicated in the tables, which exclude certain business combination accounting entries related to the acquisitions of Online Resources and significant transaction related expenses, as well as other significant non-cash expenses such as depreciation, amortization and share-based compensation, that we believe are helpful in understanding our past financial performance and our future results. The presentation of these non-GAAP financial measures should be considered in addition to our GAAP results and are not intended to be considered in isolation or as a substitute for the financial information prepared and presented in accordance with GAAP. Management generally compensates for limitations in the use of non-GAAP financial measures by relying on comparable GAAP financial measures and providing investors with a reconciliation of non-GAAP financial measures only in addition to and in conjunction with results presented in accordance with GAAP. We believe that these non-GAAP financial measures reflect an additional way of viewing aspects of our operations that, when viewed with our GAAP results, provide a more complete understanding of factors and trends affecting our business. Certain non-GAAP measures include: Non-GAAP revenue: revenue plus deferred revenue that would have been recognized in the normal course of business by Online Resources if not for GAAP purchase accounting requirements. Non-GAAP revenue should be considered in addition to, rather than as a substitute for, revenue. Non-GAAP operating income: operating income plus deferred revenue that would have been recognized in the normal course of business by Online Resources if not for GAAP purchase accounting requirements and significant transaction related expenses. Non-GAAP operating income should be considered in addition to, rather than as a substitute for, operating income. Adjusted EBITDA: net income plus income tax expense, net interest income (expense), net other income (expense), depreciation, amortization and non-cash compensation, as well as deferred revenue that would have been recognized in the normal course of business by Online Resources if not for GAAP purchase accounting requirements and significant transaction related expenses. Adjusted EBITDA should be considered in addition to, rather than as a substitute for, operating income. UP MEETS THE CHALLENGE OF CHANGE ACI UNIVERSAL PAYMENTS 25

Non-GAAP Financial Measures
ACI is also presenting operating free cash flow, which is defined as net cash provided by operating activities, plus payments associated with the cash settlement of acquisition related options and significant acquired opening balance sheet liabilities, plus net after-tax payments associated with employee-related actions and facility closures, net after-tax payments associated with significant transaction related expenses, net after-tax payments associated with IBM IT outsourcing transition and termination, and less capital expenditures. Operating free cash flow is considered a non-GAAP financial measure as defined by SEC Regulation G. We utilize this non-GAAP financial measure, and believe it is useful to investors, as an indicator of cash flow available for debt repayment and other investing activities, such as capital investments and acquisitions. We utilize operating free cash flow as a further indicator of operating performance and for planning investing activities. Operating free cash flow should be considered in addition to, rather than as a substitute for, net cash provided by operating activities. A limitation of operating free cash flow is that it does not represent the total increase or decrease in the cash balance for the period. This measure also does not exclude mandatory debt service obligations and, therefore, does not represent the residual cash flow available for discretionary expenditures. We believe that operating free cash flow is useful to investors to provide disclosures of our operating results on the same basis as that used by our management.

Non-GAAP Financial Measures
ACI also includes backlog estimates, which include all software license fees, maintenance fees and services specified in executed contracts, as well as revenues from assumed contract renewals to the extent that we believe recognition of the related revenue will occur within the corresponding backlog period. We have historically included assumed renewals in backlog estimates based upon automatic renewal provisions in the executed contract and our historic experience with customer renewal rates.
Backlog is considered a non-GAAP financial measure as defined by SEC Regulation G. Our 60-month backlog estimate represents expected revenues from existing customers using the following key assumptions:
Maintenance fees are assumed to exist for the duration of the license term for those contracts in which the committed maintenance term is less than the committed license term.
License, facilities management, and software hosting arrangements are assumed to renew at the end of their committed term at a rate consistent with our historical experiences.
Non-recurring license arrangements are assumed to renew as recurring revenue streams.
Foreign currency exchange rates are assumed to remain constant over the 60-month backlog period for those contracts stated in currencies other than the U.S. dollar.
Our pricing policies and practices are assumed to remain constant over the 60-month backlog period.
Estimates of future financial results require substantial judgment and are based on a number of assumptions as described above. These assumptions may turn out to be inaccurate or wrong, including for reasons outside of management’s control. For example, our customers may attempt to renegotiate or terminate their contracts for a number of reasons, including mergers, changes in their financial condition, or general changes in economic conditions in the customer’s industry or geographic location, or we may experience delays in the development or delivery of products or services specified in customer contracts which may cause the actual renewal rates and amounts to differ from historical experiences. Changes in foreign currency exchange rates may also impact the amount of revenue actually recognized in future periods. Accordingly, there can be no assurance that contracts included in backlog estimates will actually generate the specified revenues or that the actual revenues will be generated within the corresponding 60-month period.
Backlog should be considered in addition to, rather than as a substitute for, reported revenue and deferred revenue.
