45.6%
and
8.1%
for the
three
months ended

31,
2020
and
2019,
respectively. The Company’s estimated effective income tax rate for the

was impacted primarily by costs associated with the acquisition of Geneva that are expected to be non-deductible for tax purposes. The Company’s estimated effective income tax rate for the
three
months ended
March 
31,
2019
was impacted by the estimated changes in the Company’s valuation allowance.
