| Income Taxes | Note 11. Income Taxes The Company recorded provisions for income taxes of $4,845,000 and $4,653,000 for the three months ended September 30, 2011 and 2010, respectively. The effective tax rate was 36.3% and 39.2% for the three months ended September 30, 2011 and 2010, respectively. The effective tax rate of 36.3% is estimated to be higher than the federal statutory rate primarily due to the impact of state taxes, stock option expenses, and the expiration of federal research & development tax credits on December 31, 2011. As of September 30, 2011, the Company had a liability for gross unrecognized tax benefits of $7,224,000, substantially all of which, if recognized, would affect the Company's effective tax rate. During the three months ended September 30, 2011, there was no material change in the total amount of the liability for gross unrecognized tax benefits. The Company's policy is to include interest and penalties related to unrecognized tax benefits within the provision for taxes on the consolidated statements of operations. As of September 30, 2011, the Company had a liability for accrued interest and penalties related to the unrecognized tax benefits of $662,000. During the three months ended September 30, 2011, there was no material change in the total amount of the liability for accrued interest and penalties related to the unrecognized tax benefits. The Company files U.S. federal, U.S. state, and foreign income tax returns. The Company is generally no longer subject to tax examinations for years prior to the fiscal year beginning July 1, 2003. It is reasonably possible that the total amount of unrecognized tax benefits will increase or decrease in the next 12 months. Such changes could occur based on the normal expiration of various statues of limitations or the possible conclusion of ongoing tax examinations in various jurisdictions. The Company is currently under audit by the Internal Revenue Service and the Netherlands tax authorities, but does not expect the outcome of these examinations will have a material impact on its financial position, results of operations or liquidity in the next 12 months. |
