Income Taxes [Abstract]
Income Taxes	7. INCOME TAXES Our consolidated effective income tax rate for the three and six months ended March 31, 2012 was approximately 6% and 12%, respectively, which includes an approximate $6.4 million tax benefit recognized during the current quarter related to the settlement of a foreign tax examination. We record estimated accrued interest and penalties related to uncertain tax positions as income tax expense. At March 31, 2012, we had approximately $8.1 million of reserves for uncertain tax positions, including estimated accrued interest and penalties of $2.1 million, which are included in Other Long Term Liabilities in the Consolidated Balance Sheet. None of our reserves for uncertain tax positions relate to timing differences. Accordingly, all $8.1 million of the net uncertain tax liabilities would affect the effective tax rate if recognized. Our United States tax returns for fiscal year 2008 and subsequent years remain subject to examination by tax authorities. As we conduct business globally, we have various tax years that remain open to examination in various international tax jurisdictions. We do not anticipate that any tax contingencies resolved during the next 12 months will have a material impact on our consolidated financial position, results of operations or cash flows.

7. INCOME TAXES

Our consolidated effective income tax rate for the three and six months ended March 31, 2012 was approximately 6% and 12%, respectively, which includes an approximate $6.4 million tax benefit recognized during the current quarter related to the settlement of a foreign tax examination.

We record estimated accrued interest and penalties related to uncertain tax positions as income tax expense. At March 31, 2012, we had approximately $8.1 million of reserves for uncertain tax positions, including estimated accrued interest and penalties of $2.1 million, which are included in Other Long Term Liabilities in the Consolidated Balance Sheet. None of our reserves for uncertain tax positions relate to timing differences. Accordingly, all $8.1 million of the net uncertain tax liabilities would affect the effective tax rate if recognized.

Our United States tax returns for fiscal year 2008 and subsequent years remain subject to examination by tax authorities. As we conduct business globally, we have various tax years that remain open to examination in various international tax jurisdictions. We do not anticipate that any tax contingencies resolved during the next 12 months will have a material impact on our consolidated financial position, results of operations or cash flows.
