Income Taxes	NOTE 11. INCOME TAXES The Company's effective income tax rate for first quarter of fiscal 2012 was 17.0%, as compared to 16.0% for the first quarter of fiscal 2011 primarily due to the expiration of federal R&D credit for 2012.

NOTE 11. INCOME TAXES

The Company's effective income tax rate for first quarter of fiscal 2012 was 17.0%, as compared to 16.0% for the first quarter of fiscal 2011 primarily due to the expiration of federal R&D credit for 2012. The 2012 and 2011 first quarter effective income tax rates were lower than the statutory federal income tax rate of 35% primarily due to geographical mix of the Company's pre-tax income.

The Company and its subsidiaries are subject to U.S. federal and state, and foreign income tax. The Company has substantially concluded all U.S. federal income tax audits for years through 2009 with the exception of acquired companies. State income tax matters have been concluded for years through 1992 and non-U.S. income tax matters have been concluded for years through 2000. The Company is currently in various stages of multiple year examinations by federal, state, and foreign (including France and Germany) taxing authorities. Although the timing of resolution and/or closure on audits is highly uncertain, the Company does not believe that the unrecognized tax benefits would materially change in the next twelve months.

The unrecognized tax benefits of $34.3 million and $28.7 million as of the first quarter of fiscal 2012 and fiscal year end 2011, respectively, if recognized, would favorably affect the effective income tax rate in future periods. Unrecognized tax benefits are recorded in Other non-current liabilities and in the deferred tax accounts in the accompanying Condensed Consolidated Balance Sheets.

The Company's practice is to recognize interest and/or penalties related to income tax matters in income tax expense. The Company's unrecognized tax benefit liabilities include interest and penalties as of the first quarter of fiscal 2012 and fiscal year end 2011, of $3.2 million and $2.7 million, respectively, which were recorded in Other non-current liabilities in the accompanying Condensed Consolidated Balance Sheets.
