Income Taxes

6 Months Ended

Jun. 30, 2020

The gross liability for unrecognized tax benefits at June 30, 2020 and December 31, 2019 was $17,122 and $15,356, respectively, exclusive of interest and penalties, of which $17,097 and $15,194 would affect the effective tax rate if the Company were to recognize the tax benefit.

The Company classifies interest and penalties on unrecognized tax benefits as income tax expense. As of June 30, 2020 and December 31, 2019, the combined amount of accrued interest and penalties related to tax positions taken on tax returns was $2,387 and $1,962, respectively.

The Company's effective income tax rate for the three and six months ended June 30, 2020 and 2019 differs from the federal income tax statutory rate due to the following:


	Three Months Ended June 30,						Six Months Ended June 30,
	2020		2019		2020		2019
Statutory rate	21.0	%	21.0	%	21.0	%	21.0	%
State taxes, net of federal tax benefit	3.3		2.6		3.2		2.6
Foreign tax expense and tax rate differential	(0.2)		(0.1)		(0.1)		(0.1)
Tax benefit from stock option exercises	(0.4)		(1.1)		(1.3)		(1.1)


Other, net	(0.4)		(0.3)		(0.4)		(0.3)
	23.3	%	22.1	%	22.4	%	22.1	%

The increase in the Company's effective tax rate for the three months ended June 30, 2020 was primarily due to decreased tax benefits related to the lower volume of stock option exercises as compared to the three months ended June 30, 2019 as well as an increase in the state effective tax rate.

The Company files income tax returns in the United States on a consolidated basis and in many U.S. state and foreign jurisdictions. The Company is subject to examination of income tax returns by the Internal Revenue Service (IRS) and other domestic and foreign tax authorities. The Company is no longer subject to U.S. federal income tax examination for years before 2016 and is no longer subject to state, local or foreign income tax examinations by authorities for years before 2015.

The Company estimates it will recognize $4,950 of gross unrecognized tax benefits. This amount is expected to be paid within one year or to be removed at the expiration of the statute of limitations and resolution of income tax audits and is netted against the current payable account. These unrecognized tax benefits are related to tax positions taken on certain federal, state, and foreign tax returns. However, the timing of the resolution of income tax examinations is highly uncertain, and the amounts ultimately paid, if any, upon resolution of the issues raised by the taxing authorities may differ materially from the amounts accrued for each year. While it is reasonably possible that some issues under examination could be resolved in the next twelve months, based upon the current facts and circumstances, the Company cannot reasonably estimate the timing of such resolution or the total range of potential changes as it relates to the current unrecognized tax benefits that are recorded as part of the Company’s financial statements.
