Note on Non-GAAP Financial Measures As used in this press release the term “reported” refers to measures under accounting principles generally accepted in the United States (“GAAP”). The term “adjusted” refers to non-GAAP operating performance measures that exclude special items such as restructuring and integration charges, amortization expense, excess tax benefits ("ETB") associated with stock-based compensation, gains and losses associated with changes in the carrying value of our strategic investments and other items. 2 Non-GAAP adjusted measures are presented because management believes those measures are useful adjuncts to GAAP results. Non-GAAP adjusted measures should not be considered as an alternative to the corresponding measures determined under GAAP. Management may use these non-GAAP measures to evaluate our performance peri
