Certain items such as changes in tax rates and tax benefits related to disqualifying dispositions of incentive stock options are treated as discrete items and are recorded in the period in which they arise.

Income tax benefit for the three months ended March 31, 2015 was $0.2 million resulting from losses of $0.5 million in the period. Income tax expense increased by $1.3 million during the three months ended March 31, 2016 compared to the prior year period due primarily to a $2.8 million increase in income before taxes during the current year period.
