U.S. income taxes have not been provided on the undistributed earnings of international subsidiaries, as those earnings are considered to be permanently reinvested in the operations of those subsidiaries. Management has determined that $423 and $1,117 of valuation allowance was necessary at December 31, 2011 and 2010, respectively, to reduce the deferred tax assets to the amount that will more likely than not be realized. At December 31, 2011, there were state and other net operating loss carryforwards of $9,491, which expire in varying amounts from 2012 through 2031. These amounts are available to offset future taxable income. There were no federal net operating loss carryforwards at December 31, 2011. We are subject to U.S. federal income tax, income tax of multiple state jurisdictions and foreign income tax. We are subject to tax audits in the various jurisdictions until the respective statutes of limitations expire. We are no longer subject to U.S. federal tax examinations for tax years prior to 2008. For the majority of states, we are no longer subject to tax examinations for tax years prior to 2007. As of December 31, 2011 and 2010, the total amount of gross unrecognized tax benefits (excluding the federal benefit received from state positions) was $2,424 and $1,889, respectively. Of these totals, $1,773 and $1,419, respectively, (net of the federal benefit received from state positions) represent the amount of unrecognized tax benefits that, if recognized, would affect the effective tax rate. Our continuing practice is to recognize penalties within selling, general and administrative expenses and interest related to income tax matters in income tax expense in the consolidated statements of income. As of December 31, 2011 and 2010, the cumulative amount of estimated accrued interest and penalties resulting from such unrecognized tax benefits was $495 and $379, respectively, and is included in deferred income taxes and other liabilities in the accompanying consolidated balance sheets. The change in gross unrecognized tax benefits during 2011 and 2010 is as follows:
Gross balance at January 1, 2010 |  | $ | 1,990 |
Additions based on tax positions related to the current year |  |  | 197 |
Reductions due to lapse of applicable statute of limitations |  |  | (298 | )
Gross balance at December 31, 2010 |  |  | 1,889 |
Additions based on tax positions related to the current year |  |  | 542 |
Reductions due to lapse of applicable statute of limitations |  |  | (7 | )
Gross balance at December 31, 2011 |  | $ | 2,424 |
