Questions and Answers
In order to provide projections with respect to non-GAAP measures, we are required to estimate GAAP
measures that are components of these reconciliations. The provision of these estimates is in no way meant
to indicate that the company is explicitly or implicitly providing projections on those GAAP components of the
reconciliations. In order to reconcile the non-GAAP financial measures to GAAP, the company has estimated
the GAAP components
that arithmetically add up to the non-GAAP financial measures. The company fully
expects that the estimates used for the GAAP components will vary from actual results.
