For each of the six month periods ended June 30, 2019 and 2018, the Company recorded a discrete tax benefit of $3.2 million, primarily due to activity associated with equity awards. For the three months ended June 30, 2019 and 2018, the Company recorded a discrete tax benefit of $1.4 million and $0.9 million, respectively, also primarily due to activity associated with equity awards.
