Use and economic substance of non-GAAP financial measures
Net revenue on a constant currency basis excludes the effect of foreign currency exchange fluctuations calculated by translating current period revenues using monthly exchange rates from the comparative period and excluding any hedging impact recognized in the current period. Non-GAAP operating margin is defined to exclude the effects of any amounts relating to restructuring and other charges, acquisition and divestiture charges, and amortization of intangible assets. Non-GAAP net earnings and non-GAAP diluted net EPS consist of net earnings or diluted net EPS excluding those same charges, defined benefit plan settlement charges, non-operating retirement related (credits)/charges, debt extinguishment costs, tax adjustments and the amount of additional taxes or tax benefits associated with each non-GAAP item.
