10. Income Taxes

At September 28, 2013, we had $1.6 million of net unrecognized tax benefits, $1.1 million of which would affect our effective tax rate if recognized. We recognize interest and penalties related to uncertain tax positions in income tax expense. As of September 28, 2013, we had approximately $0.2 million of accrued interest related to uncertain tax positions.

We file income tax returns in the United States. All years before 2010 are closed for federal tax purposes. In regards to state tax, we are currently under examination by one state tax authority for the years 2008-2010. Tax years before 2009 are closed for the remaining states in which we file. We filed tax returns in Sweden through 2012 and all years prior to 2008 are closed. It is reasonably possible that audit settlements, the conclusion of current examinations or the expiration of the statute of limitations could impact the Company’s unrecognized tax benefits.
