Adjusted EBITDA
We present Group adjusted EBITDA, a non-GAAP performance measure, to supplement our results presented in accordance with U.S. GAAP. Group adjusted EBITDA is defined as earnings before interest, income tax, depreciation and amortization and other items that are unusual or not related to our revenue-generating operations, including stock based compensation expense.
Group adjusted EBITDA is used by management to evaluate our core operating performance on a comparable basis and to make strategic decisions. We believe Group adjusted EBITDA is useful to investors for the same reasons as well as in evaluating our operating performance against competitors, which commonly disclose similar performance measures. However, our calculation of Group adjusted EBITDA may not be comparable to other similarly titled performance measures of other companies. Group adjusted EBITDA is not intended to be a substitute for any U.S. GAAP financial measure.
We do not provide a reconciliation of Group adj. EBITDA to consolidated net income/(loss) on a forward-looking basis because we are unable to forecast certain items required to develop meaningful comparable GAAP financial measures without unreasonable efforts. These items are difficult to predict and estimate and are primarily dependent on future events. The impact of these items could be significant to our projections.
Constant Currency
Certain income statement items in this press release are discussed on a constant currency basis. Our results between periods may not be comparable due to foreign currency translation effects. We present certain income statement items on a constant currency basis, as if GBP:USD exchange rate had remained constant period-over-period, to enhance the comparability of our results. We calculate income statement constant currency amounts by taking the relevant average GBP:USD exchange rate used in the preparation of our income statement for the more recent comparative period and apply it to the actual GBP amount used in the preparation of our income statement for the prior comparative period.
Constant currency amounts only adjust for the impact related to the translation of our consolidated financial statements from GBP to USD. Constant currency amounts do not adjust for any other translation effects, such as the translation of results of subsidiaries whose functional currency is other than GBP or USD, as such effects have not been material to date.
