Income Tax Disclosure [Abstract] |
Income Tax Matters | Income Tax Matters The provision for (benefit from) incomes taxes for each period presented consisted of the following (in millions of dollars):
| Quarter Ended |  | Nine Months Ended
| September 30, |  | September 30,
| 2015 |  | 2014 |  | 2015 |  | 2014
Domestic | $ | 13.4 |  |  | $ | 9.2 |  |  | $ | (149.0 | ) |  | $ | 32.2 |
Foreign | (0.8 | ) |  | — |  |  | (2.2 | ) |  | 0.9 |
Total | $ | 12.6 |  |  | $ | 9.2 |  |  | $ | (151.2 | ) |  | $ | 33.1 |
The income tax (benefit) provision for the quarters ended September 30, 2015 and September 30, 2014 was $12.6 million and $9.2 million, reflecting an effective tax rate of 36.3% and 36.7%, respectively. There was no material difference between the effective tax rate and the projected blended statutory tax rate for the quarters ended September 30, 2015 and September 30, 2014. The income tax (benefit) provision for the nine months ended September 30, 2015 and September 30, 2014 was $(151.2) million and $33.1 million, reflecting an effective tax rate of 37.7% and 37.0%, respectively. There was no material difference between the effective tax rate and the projected blended statutory tax rate for the nine months ended September 30, 2015 and September 30, 2014. The $(151.2) million income tax benefit for the nine months ended September 30, 2015 included a $184.4 million tax benefit that was recorded as a result of removing the Union VEBA net assets and related deferred tax liabilities from our consolidated financial statements. See Note 5 for disclosure regarding employee benefits. Our gross unrecognized benefits relating to uncertain tax positions were $1.6 million and $2.2 million at September 30, 2015 and December 31, 2014, respectively, of which, $0.5 million and $1.1 million would go through our income tax provision and thus impact the effective tax rate at September 30, 2015 and December 31, 2014, respectively, if the gross unrecognized tax benefits were to be recognized. We do not expect our gross unrecognized tax benefits to significantly change within the next 12 months.
