The sum of the per-share amounts for the four quarters may not always equal the annual per-share amounts due to differences in the average number of shares outstanding during the respective periods. The sum of other amounts for the four quarters may not always equal the annual amounts due to rounding. During the third quarter of 2018, we recorded a favorable adjustment of unrecognized tax benefits of $1,041 related to the lapse of statute of limitations. During the first quarter of 2018, we recorded discrete items to income tax expense as a result of the Act. See Note 7 for additional information. During the fourth quarter of 2017, we recorded pre-tax acquisition costs of $391 related to the acquisition of Vention.

During the second quarter of 2017, we recorded pre-tax acquisition costs of $13,415 related to Vention.
