Income Taxes

The Company's consolidated world-wide effective tax rate reflects the tax benefits of conducting operating activities in certain foreign jurisdictions where earnings are taxed at rates lower than U.S. statutory rates and where certain components of the Company's income are exempt from taxation. Furthermore, the Company's world-wide product development operations and intellectual property ownership has been centralized into our India and Singapore subsidiaries, respectively. Our operations in India benefit from a tax holiday which will continue through 2015; as such local India taxable income, other than passive interest and rental income, is not taxed. After the tax holiday expires taxable income generated by our India operations will be taxed at 50% of the normal 33.99% corporate tax rate for a period of five years. The Company also has a relatively low income tax rate is in Singapore in which our operations are taxed at a 10% marginal tax rate as a result of concessions granted by the local Singapore Economic Development Board for the benefit of in-country intellectual property owners. The concessionary 10% income tax rate will expire after 2015, at which time our Singapore operations will be subject to the prevailing corporate tax rate in Singapore, which is currently 17%, unless the Company reaches a subsequent agreement to extend the incentive period and the then applicable concessionary rate.

The Company recognized income tax expense of $2.3 million for the three months ended March 31, 2012. The Company’s interim period income tax provisions are based on an estimate of the effective income tax rate expected to be applicable to the corresponding annual period, after eliminating discrete items unique to the respective interim period being reported. The calculated estimated annual effective tax rate used by the Company to determine the interim income tax provision for the first quarter of 2012 was 12.52% as compared to 9.38% for the same period in 2011. The effective rate increased primarily due to increased taxable income from jurisdictions with higher tax rates.

At March 31, 2012, the Company had remaining available domestic net operating loss (“NOL”) carry-forwards of approximately $56.0 million which are available to offset future federal and certain state income taxes. The Company expects to fully utilize these NOLs before they begin to expire in 2020.

Accounting for Uncertainty in Income Taxes—The Company has applied the FASB’s accounting guidance on accounting for uncertain income tax positions. As of March 31, 2012 the Company’s Condensed Consolidated Balance Sheet includes a liability of $3.18 million for unrecognized tax benefits which is included in other long-term liabilities. During the three months ended March 31, 2012 there were no changes to this liability. A reconciliation of the beginning and ending amount of the Company’s liability reserves for unrecognized tax benefits is as follows:



	(in thousands)
Balance at January 1, 2012	$	3,180
Additions for tax positions related to current year	$	—
Additions for tax positions of prior years	$	—
Reductions for tax position of prior years	$	—
Balance at March 31, 2012	$	3,180

The Company recognizes interest accrued and penalties related to unrecognized tax benefits as part of income tax expense. As of March 31, 2012 approximately $754 thousand of estimated interest and penalties is included in other long-term liabilities in the accompanying Condensed Consolidated Balance Sheet.

Based on its current knowledge and the probability assessment of potential outcomes, the Company believes that recorded tax reserves, as determined in accordance with the requisite income tax guidance, are adequate.
