Our state income tax returns have been examined or are closed by statute for all years prior to fiscal year 2009, and we are no longer subject to audit for those periods. Tax authorities for certain non-U.S. jurisdictions are also examining returns affecting unrecognized tax benefits, none of which are material to our condensed consolidated balance sheets, cash flows or statements of income.

Our income tax provision for the first quarter of fiscal year 2014 and 2013 reflects our estimates of the effective tax rates expected to be applicable for the full fiscal years, adjusted for any discrete events which are recorded in the period they occur. The estimates are reevaluated each quarter based on our estimated tax expense for the full fiscal year.

The research and development credit provisions in the tax code expired as of December 31, 2013 and have not been extended at this time. There is no assurance that the credit provisions will be extended during 2014.

Our Federal income tax returns have been examined or are closed by statute for all years prior to fiscal year 2011, and we are no longer subject to audit for those periods. Our state income tax returns have been examined or are closed by statute for all years prior to fiscal year 2009, and we are no longer subject to audit for those periods.

Tax authorities for certain non-U.S. jurisdictions are also examining returns affecting unrecognized tax benefits, none of which are material to our condensed consolidated balance sheets, cash flows or statements of income. With some exceptions, we are generally no longer subject to tax examinations in non-U.S. jurisdictions for years prior to fiscal year 2008.
