8. Income taxes

The Company’s effective income tax rate for the Current Quarter and the Prior Year Quarter was approximately 40% and (11)%, respectively. The Prior Year Quarters effective tax rate has been adjusted by a tax benefit from the effect of a state and local rate allocation change resulting in a (50)% adjustment to the effective tax rate by virtue of applying the rate differential to the opening net deferred tax liability.
