Income Tax Disclosure [Abstract] |
Income Taxes |
5. | INCOME TAXES
Income taxes are recognized for the amount of taxes payable or refundable for the current year and deferred tax liabilities and assets for the future tax consequences of events that have been recognized in our consolidated financial statements or tax returns. The effects of income taxes are measured based on enacted tax laws and rates. As of September 30, 2016 and December 31, 2015, we had $15.2 million and $12.2 million of gross unrecognized tax benefits. As of September 30, 2016, if such benefits were to be recognized, approximately $12.2 million would be recorded as a component of income tax expense, thereby affecting our effective tax rate. We, or one of our subsidiaries, file income tax returns with the United States Internal Revenue Service, as well as various state and foreign authorities. The following table summarizes, by major jurisdiction, tax years that remain subject to examination:
| Open Tax Years
Jurisdiction | Examinations not yet initiated |  | Examination in progress
United States |  |  |
Federal | 2013 - 2015 |  | N/A
State | 2011 - 2015 |  | 2014
Canada (1) | 2010 - 2015 |  | N/A
Germany (1) | 2012 - 2015 |  | 2007 - 2011
France | 2013 - 2015 |  | 2011 - 2012
United Kingdom | 2014 - 2015 |  | N/A
Philippines | 2015 |  | 2013, 2014
(1) | includes provincial or similar local jurisdictions, as applicable
The amount of income taxes we pay is subject to ongoing audits by federal, state and foreign tax authorities, which often result in proposed assessments. Management performs a comprehensive review of its global tax positions on a quarterly basis and accrues amounts for uncertain tax positions. Based on these reviews and the result of discussions and resolutions of matters with certain tax authorities and the closure of tax years subject to tax audit, reserves are adjusted as necessary. However, future results may include favorable or unfavorable adjustments to our estimated tax liabilities in the period the assessments are determined or resolved or as such statutes are closed. Due to potential for resolution of federal, state and foreign examinations, and the lapse of various statutes of limitation, it is reasonably possible our gross unrecognized tax benefits balance may decrease within the next twelve months by a range of zero to $1.8 million. Substantially all of this range relates to tax positions taken in Germany. We recognize interest and penalties related to uncertain tax positions as income tax expense. The following table summarizes information related to interest and penalties on uncertain tax positions:
| Nine months ended September 30 |

Penalties |  | — |  |  |  | — |
