Forrester provides for income taxes on an interim basis according to management’s estimate of the effective tax rate expected to be applicable for the full fiscal year. 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 expense for the six months ended June 30, 2016 was $5.5 million resulting in an effective tax rate of 38.7% for the period. Income tax expense for the six months ended June 30, 2015 was $4.0 million resulting in an effective tax rate of 42.1% for the period. The decrease in the effective tax rate for the six months ended June 30, 2016 compared to the prior year period was primarily due to a decrease in non-deductible stock compensation during 2016 as compared to 2015 and the inclusion of a $0.3 million non-deductible loss on the liquidation of a foreign subsidiary in the 2015 period that did not recur in 2016.
