8. INCOME TAXES
Our effective tax rates were 16.5 percent and 63.8 percent for the three months ended March 31, 2018 and 2017, respectively. The 2018 rate is lower due to the lower Federal tax rate enacted by the Tax Cuts and Jobs Act and the impact of discrete benefits related to share-based compensation. The 2017 rate was higher due to a small overall pre-tax loss and the impact of discrete benefits related to share-based compensation and a legal settlement.
Our Condensed Consolidated Statements of Operations recognized a discrete tax benefit of $2.6 million, and $0.8 million related to share-based compensation, for the three months ended March 31, 2018 and 2017, respectively. A discrete benefit of $11.8 million related to a legal settlement was recognized for the three months ended March 31, 2017.
