The statutory federal income tax rate is reconciled to the effective income tax rate as follows:
|  | 2012 |  |  | 2011 |  |  | 2010 |
Statutory federal income tax rate |  |  | 35 | % |  |  | 35 | % |  |  | 35 | %

Effective tax rate |  |  | 40 | % |  |  | 43 | % |  |  | 43 | %
Our effective income tax rate decreased to 39.9% in 2012 from 42.5% in 2011 primarily due to a decrease to our deferred income tax liability as a result of a change in income apportionment for several states. As of December 31, the net deferred tax liability consisted of the following:
(In thousands) |  | 2012 |  |  | 2011 |
Deferred tax assets: |  |  |  |  |  |
Reserves and accrued liabilities |  | $ | 5,687 |  |  | $ | 5,326 |
Other |  |  | 2,714 |  |  |  | 2,274 |
|  |  | 8,401 |  |  |  | 7,600 |
Deferred tax liabilities: |  |  |  |  |  |  |  |
Depreciation |  |  | 111,794 |  |  |  | 106,113 |
Prepaid expenses |  |  | 2,526 |  |  |  | 2,584 |
|  |  | 114,320 |  |  |  | 108,697 |
Net deferred tax liability |  | $ | 105,919 |  |  | $ | 101,097 |
We have not provided a valuation allowance against deferred tax assets at December 31, 2012 or 2011. We believe the deferred tax assets will be realized principally through future reversals of existing taxable temporary differences (deferred tax liabilities) and future taxable income. Our reserves for unrecognized tax benefits were $281,000 as of December 31, 2012 and $288,000 as of December 31, 2011. The $7,000 decrease in the amount reserved in 2012 relates to current period tax positions offset by the removal of the reserve relating to 2007. The amount reserved as of December 31, 2011 was added in 2007 through 2011 relating to current period tax positions. If recognized, $183,000 of the unrecognized tax benefits as of December 31, 2012 would impact our effective tax rate. No potential interest or penalties related to unrecognized tax benefits were recognized in our financial statements as of December 31, 2012. We do not expect the reserves for unrecognized tax benefits to change significantly within the next twelve months. The federal statute of limitations remains open for 2009 and forward. We file tax returns in numerous state jurisdictions with varying statutes of limitations.
