INTERNAP NETWORK SERVICES CORPORATION
NON-GAAP (ADJUSTED) FINANCIAL MEASURES
In addition to providing financial measurements based on generally accepted accounting principles in the United States of America (GAAP), Internap has historically provided additional financial measures that are not prepared in accordance with GAAP (non-GAAP), including adjusted EBITDA, normalized net income (loss), adjusted gross margin and normalized diluted shares. The most directly comparable GAAP equivalent to adjusted EBITDA and normalized net income (loss) is net income (loss). The most directly comparable GAAP equivalent to adjusted gross margin is gross margin. The most directly comparable GAAP equivalent to normalized diluted shares is diluted common shares outstanding.
We define non-GAAP measures as follows:
| • | | Adjusted EBITDA is net income (loss) plus stock based compensation, depreciation and amortization, asset impairment and restructuring, income taxes and interest expense less interest income |
|
| • | | Normalized net income (loss) is net income (loss) plus stock-based compensation |
|
| • | | Normalized diluted shares are diluted common shares outstanding used in GAAP net income per share calculation, excluding the effect of SFAS No. 123R under the treasury stock method |
|
| • | | Normalized net income (loss) per share is normalized net income (loss) divided by basic and normalized diluted shares |
|
| • | | Adjusted gross profit is gross profit (GAAP) plus direct cost of customer support and depreciation and amortization included in or associated with cost of sales. |
|
| • | | Adjusted gross margin is adjusted gross profit as a percentage of revenues. |
Reconciliations of each of our non-GAAP financial measures to the most directly comparable financial measure are detailed in the Reconciliations of GAAP to non-GAAP measures below. We believe that presentation of these non-GAAP financial measures provides useful information to investors regarding our results of operations.
We believe that excluding depreciation and amortization as well as restructuring and impairment to calculate adjusted EBITDA provides supplemental information and an alternative presentation that is useful to investors’ understanding of the Company’s core operating results and trends. Not only are depreciation and amortization expenses based on historical costs of assets that may have little bearing on present or future replacement costs, but also they are based on management estimates of remaining useful lives. Restructuring costs relate to differences between actual costs incurred and estimates of liabilities incurred during the implementation of restructuring plans and impairment costs relate to the Company’s write-down of certain costs that were capitalized during the development of software to be used internally. Management believes that such restructuring and impairment charges were unique costs that are not expected to recur on a regular basis, and consequently, does not consider these charges as a normal component of expenses related to current and ongoing operations.
Similarly, we believe that excluding the effects of share-based compensation from non-GAAP financial measures provides supplemental information and an alternative presentation useful to investors’ understanding of the Company’s core operating results and trends, especially when comparing those results on a consistent basis to results for previous periods and anticipated results for future periods. Investors have indicated that they consider financial measures of our results of operations excluding share-based compensation expense as important supplemental information useful to their understanding of our historical results and estimating our future results.
We also believe that, in excluding the effects of share-based compensation, our non-GAAP financial measures provide investors with transparency into what is used by management to measure and forecast our results of operations, to compare on a consistent basis our results of operations for the current period to that
of prior periods, to compare our results of operations on a more consistent basis against that of other companies, in making financial and operating decisions and to establish certain management compensation.
Stock-based compensation is an important part of total compensation, especially from the perspective of employees. However, the inclusion of stock-based compensation in the current period operating results due to the adoption of SFAS No. 123R effective January 1, 2006 makes comparisons to prior period results more difficult. Therefore we believe that supplementing GAAP net income (loss) and net income (loss) per share information by providing normalized net income (loss) and normalized net income (loss) per share for those periods, excluding the effect of stock-based compensation expense in all periods, is useful to investors because it enables additional and more meaningful period-to-period comparisons. We consider normalized diluted shares to be another important indicator of overall performance of the Company because it eliminates the effect of a non-cash item.
Adjusted EBITDA is not a measure of liquidity calculated in accordance with accounting principles generally accepted in the United States, and should be viewed as a supplement to — not a substitute for — our results of operations presented on the basis of accounting principles generally accepted in the United States. Adjusted EBITDA does not purport to represent cash flow provided by, or used in, operating activities as defined by accounting principles generally accepted in the United States. Our statement of cash flows presents our cash flow activity in accordance with accounting principles generally accepted in the United States. Furthermore, adjusted EBITDA is not necessarily comparable to similarly-titled measures reported by other companies.
We believe adjusted EBITDA is used by and is useful to investors and other users of our financial statements in evaluating our operating performance because it provides them with an additional tool to compare business performance across companies and across periods. We believe that:
| • | | EBITDA is widely used by investors to measure a company’s operating performance without regard to items such as interest expense, taxes, depreciation and amortization, which can vary substantially from company to company depending upon accounting methods and book value of assets, capital structure and the method by which assets were acquired; and |
|
| • | | investors commonly adjust EBITDA information to eliminate the effect of restructuring and stock-based compensation expenses, which vary widely from company to company and impair comparability. |
Our management uses adjusted EBITDA:
| • | | as a measure of operating performance to assist in comparing performance from period to period on a consistent basis; |
|
| • | | as a measure for planning and forecasting overall expectations and for evaluating actual results against such expectations; and |
|
| • | | in communications with the board of directors, shareholders, analysts and investors concerning our financial performance. |
Our presentation of adjusted gross margin excludes depreciation, amortization and direct cost of customer support in order to allow investors to see the business through the eyes of management. Direct cost of network and sales is viewed by management as generally non-controllable, external costs and the margin of revenue in excess of these direct costs is regularly monitored by management. Similarly, we view the cost of customer support to also be an important component of costs of revenue but believe that the cost of customer support to be within our control and to some degree discretionary as we can adjust that cost by hiring and terminating employees.
Adjusted gross margin is an important metric to our investors and analysts, as we have regularly discussed and disclosed the effects of third party vendors’ pricing declines and the corresponding affect on our revenue. The presentation of adjusted gross margin highlights the impact of the pricing declines and allows investors and analysts to evaluate our revenue generation performance relative to direct costs of network and sales. Conversely, we have much greater latitude in controlling the compensation component of cost of revenue, represented by customer support, and we analyze this component separately from the direct external costs.
Depreciation and amortization have also been excluded from adjusted gross margin because, as noted above, they are based on estimated useful lives of tangible and intangible assets. Further, depreciation and amortization are based on historical cost incurred to build out the Company’s deployed network and the historical costs of these assets may not be indicative of current or future capital expenditures.
Although we believe, for the foregoing reasons, that our presentation of non-GAAP financial measures provides useful supplemental information to investors regarding our results of operations, our non-GAAP financial measures should only be considered in addition to, and not as a substitute for, or superior to, any measure of financial performance prepared in accordance with GAAP.
Use of non-GAAP financial measures is subject to inherent limitations because they do not include all the expenses that must be included under GAAP and because they involve the exercise of judgment of which charges should properly be excluded from the non-GAAP financial measure. Management accounts for these limitations by not relying exclusively on non-GAAP financial measures, but only using such information to supplement GAAP financial measures. Our non-GAAP financial measures may not be the same non-GAAP measures, and may not be calculated in the same manner, as those used by other companies.
