|Income Tax Disclosure [Abstract]
Our effective income tax rate for the six months ended March 29, 2014, was 14.3%, compared to an effective rate of (9.6)% for the same period in the prior year and an effective rate of 7.3% for the fiscal year ended June 29, 2013. We benefit from having income in foreign jurisdictions that are either exempt from income taxes or have tax rates lower than the United States. Based on our current projected pre-tax income and the anticipated amount of U.S. taxable income compared to profits maintained in the offshore taxable and tax-free jurisdictions, our estimated effective income tax rate for the fiscal year ending September 27, 2014, is expected to be approximately 14%. Changes in the mix of U.S. taxable income compared to profits maintained in tax-free jurisdictions, however, can have a significant impact on our overall effective tax rate.
We file income tax returns in the U.S. federal jurisdiction and various state, local and foreign jurisdictions. In the December quarter of fiscal year 2013, the Internal Revenue Service commenced an examination of our U.S. income tax returns for fiscal year 2010 (tax year 2009). Upon filing the carryback of our net operating losses from fiscal year 2012 to our fiscal years 2011 and 2010 (tax years 2011 and 2010) and receiving a cash refund of the taxes previously paid, the Internal Revenue Service expanded the examination to include our U.S. income tax returns for our 2011 and 2012 fiscal years. This examination was concluded in January 2014, and no tax deficiency was found. Based on the conclusion of the audit, these returns are no longer subject to further examination by the Internal Revenue Service. However, net operating loss carryforwards remain subject to examination to the extent they are carried forward and impact a year that is open to examination by taxing authorities. The tax years 2009 to 2013, according to statute and with few exceptions, remain open to examination by various state, local and foreign jurisdictions.
