Income tax provisions for interim (quarterly) periods are based on estimated annual income tax rates and are adjusted for the effects of significant, infrequent or unusual items (i.e. discrete items) occurring during the interim period. The prior year quarter rate was impacted by $3.8 million in expenses related to the compensation of our former CEO upon his death, in accordance with his employment agreement, that were permanent differences between our book and taxable income.
