Non-GAAP Financial Measures GSI's consolidated financial statements are prepared and presented in accordance with GAAP. To supplement our consolidated financial statements, in this presentation, we use the non-GAAP financial measures of non-GAAP net revenues, non-GAAP income from operations and free cash flow. We also discuss certain ratios that use those measures. The non-GAAP measures and ratios presented are not intended to be considered in isolation of, as a substitute for, or superior to our GAAP financial information. We have included reconciliations later in this release of the non-GAAP measures to the nearest GAAP measure. We use these non-GAAP financial measures for financial and operational decision making and as a means to evaluate our performance. In our opinion, these non-GAAP measures provide meaningful supplemental information regarding our performance. We believe that both management and investors benefit from referring to these non-GAAP financial measures in assessing our performance and when planning, forecasting and analyzing future periods. These non-GAAP financial measures also facilitate management's internal comparisons to our historical performance and liquidity. We believe these non-GAAP financial measures are useful to investors both because (1) they allow for greater transparency with respect to key metrics used by management in its financial and operational decision making and (2) they are used by institutional investors and the analyst community to help them analyze the health of our business. These measures may be different from non-GAAP measures used by other companies. Non-GAAP net revenues. We define non-GAAP net revenues as net revenues minus cost of revenues from product sales and marketing expenses. Marketing expenses principally include client revenue share expenses, net advertising and promotional expenses, subsidized shipping and handling expenses, and catalog expenses. We consider non-GAAP net revenues to be a useful metric for management and investors because (1) it provides a metric for our investors to understand and analyze our company and (2) it provides investors with one of the primary metrics used by the company for evaluation and decision making purposes. We and many of our investors view us as a technology and business services company. Since most technology and business service companies generate their revenues from service fees and do not have product sales, we believe that by subtracting cost of revenues from product sales and marketing expenses from our net revenues from product sales, the company and investors will be better able to assess our revenues on a basis that more closely approximates the net revenues of other technology and business services companies. Further, management uses this metric for evaluating the performance of our business, making operating decisions and for budgeting purposes. Non-GAAP income from operations. We define non-GAAP income from operations as income from operations excluding stock-based compensation, depreciation and amortization expenses, and transaction and due diligence and integration expenses relating to acquisitions. We consider non-GAAP income from operations to be a useful metric for management and investors because it excludes certain non-cash and non-operating items. Because of varying available valuation methodologies, subjective assumptions and the variety of award types that companies can use when valuing equity awards under SFAS 123R, we believe that viewing income from operations excluding stock-based compensation expense allows investors to make meaningful comparisons between our operating performance and those of other businesses. Because we are growing our business and operate in an emerging and changing industry, we believe that our level of capital expenditures and consequently the level of depreciation and amortization expense relative to our revenues could be meaningfully greater today than it will be over time. As a result, we believe it is useful supplemental information to view income from operations excluding depreciation and amortization expense as it provides a potential indicator of the future operating margin potential of the business. We believe the exclusion of acquisition-related integration, transaction and due diligence expense permits evaluation and a comparison of results for on-going business operations, and it is on this basis that management internally assesses the company's performance. Free cash flow. We define free cash flow as net cash provided by operating activities minus cash paid for fixed assets, including internal use software. We consider free cash flow to be a liquidity measure that provides useful information to management and investors about the amount of cash generated by the business that, after the acquisition of property and equipment, including information technology infrastructure, can be used for strategic opportunities, including investing in the business, making strategic acquisitions and strengthening the balance sheet. Analysis of free cash flow also facilitates management's comparisons of our operating results to the operating results of comparable companies. A limitation of using free cash flow as a means for evaluating our performance is that free cash flow reflects changes in working capital which is impacted by short-term changes in cash flow and the seasonality of our business which may not be indicative of long-term performance. Another limitation of free cash flow is that it excludes fixed assets purchased and placed in service, but not paid for during the applicable period. Our management compensates for this limitation by providing supplemental information about capital expenditures accrued, but not paid for during the applicable periods on the face of the cash flow statement in our Forms 10-K and 10-Q.

GSI's Revenue Model FY2008 Marketing GSI records certain revenues gross (product sales) and certain revenues net (services fees). Internally, GSI adjusts revenue to view all revenue streams on a more comparable economic basis. It is how the company evaluates growth, margin trends and client concentration. GSI views itself as a business and technology services company. As a result, the company nets all transactions down instead of grossing them up like a traditional retailer. $ in millions overview e-commerce services interactive marketing services financials $475.5 non-GAAP net revenue $491.4 $966.9 net revenue Costs of revenues from product sales $70.3 (subsidized shipping, advertising costs, catalog costs and revenue share charges) $405.2
