(12) Income Taxes

The Company had approximately $2.2 million of total gross unrecognized tax benefits including interest for both periods ended September 30, 2011 and June 30, 2011. Of this total, approximately $1.8 million represents the amount of unrecognized tax benefits that are permanent in nature and, if recognized, would affect the annual effective tax rate in both periods. The Company does not believe that the total amount of unrecognized tax benefits will significantly increase or decrease within twelve months of the reporting date.

The Company conducts business globally and, as a result, one or more of its subsidiaries files income tax returns in the U.S. federal, various state, local and foreign jurisdictions. In the normal course of business, the Company is subject to examination by taxing authorities in countries in which it operates. With few exceptions, the Company is no longer subject to state and local, or non-U.S. income tax examinations by tax authorities for the years before 2008.

The Company's continuing practice is to recognize interest and penalties related to income tax matters in income tax expense. As of September 30, 2011, the Company had approximately $1.0 million accrued for interest and penalties, $0.1 million of which was a current period expense.

Income taxes for the interim period presented have been included in the accompanying condensed consolidated financial statements on the basis of an estimated annual effective tax rate. In addition to the amount of tax resulting from applying the estimated annual effective tax rate to pre-tax income, the Company includes certain items treated as discrete events to arrive at an estimated overall tax amount. There were no significant discrete items in the period.

The Company's effective tax rate differs from the federal statutory rate of 35% primarily as a result of income derived from tax jurisdictions with varying income tax rates.
