We recorded income tax expense of $300,000 and $453,000 for the three and six months ended June 30, 2012. We record our interim provision for income taxes based on our estimated annual effective tax rate for the year. Differences between our effective tax rate and statutory tax rates are primarily due to the impact of meals, entertainment and employee stock purchase plan expenses, as well as the federal R&D credit. Our provisions for income taxes included current foreign and state income tax expense, as well as deferred tax expense. The decrease in income tax expense for the six months ended June 30, 2013, compared to the six months ended June 30, 2012, was primarily due to a discrete tax benefit of $117,000 in 2013 for the retroactive benefit of the 2012 federal R&D credit. The American Taxpayer Relief Act of 2012 was enacted on January 2, 2013 and extended the federal R&D credit from January 1, 2012 through December 31, 2013. We are subject to income taxes in the U.S. federal and various state and international jurisdictions. As of June 30, 2013, we are generally subject to tax examinations for all prior years due to our net operating loss carryforwards. As of June 30, 2013, we do not have any unrecognized tax benefits. It is our practice to recognize interest and penalties accrued on any unrecognized tax benefits as a component of income tax expense. We do not expect any material changes in our unrecognized tax positions over the next 12 months. </div>falsefalsefalsenonnum:textBlockItemTypenaThe entire disclosure for income taxes.
