Anti-dilutive shares related to outstanding stock options and unvested RSUs (A)		110		239		89		253

(A)

Certain outstanding stock options were not included in the computation of diluted income per share because the options’ exercise prices were greater than the average market price of the common stock and, therefore, the effect would be anti-dilutive. Certain RSUs were also excluded from the computation as their effect would be anti-dilutive. Performance based RSU’s that have not yet been earned have also been excluded from the computation of diluted income per share.
