INCOME TAXES

The Company does not recognize a tax benefit unless the Company concludes that it is more likely than not that the benefit will be sustained on audit by the taxing authority based solely on the technical merits of the associated tax position. If the recognition threshold is met, the Company recognizes a tax benefit measured at the largest amount of the tax benefit that the Company believes is greater than 50% likely to be realized.

The gross unrecognized income tax benefits were $25.6 and $18.0 at June 30, 2019, and December 31, 2018, respectively. It is anticipated that the amount of the unrecognized income tax benefits will change within the next 12 months; however, these changes are not expected to have a significant impact on the results of operations, cash flows or the financial position of the Company.

As of June 30, 2019, and December 31, 2018, $25.6 and $18.0, respectively, are the approximate amounts of gross unrecognized income tax benefits that, if recognized, would favorably affect the effective income tax rate in future periods.

The Company recognizes interest and penalties related to unrecognized income tax benefits in income tax expense. Accrued interest and penalties related to uncertain tax positions totaled $10.3 and $8.7 as of June 30, 2019, and December 31, 2018, respectively.

The Company has substantially concluded all U.S. federal income tax matters for years through 2014. Substantially all material state and local, and foreign income tax matters have been concluded through 2013 and 2014, respectively.

The IRS has not initiated a new examination of any of the Company's federal income tax returns. The Company has various state and foreign income tax examinations ongoing throughout the year. The Company believes adequate provisions have been recorded related to all open tax years.
