12. Income Taxes

Intevac’s effective income tax rate for the three and nine months ended October 1, 2011 was 21.3% and 27.4%, respectively. Intevac’s effective income tax rate for the three and nine months ended October 2, 2010 was 13.7% and 14.5%, respectively. Intevac adjusts its effective income tax rate each quarter to be consistent with the estimated annual effective income tax rate. The effective income tax rate differs from the applicable statutory rates due primarily to the utilization of deferred and current credits, the effect of permanent differences and the geographical composition of Intevac’s worldwide earnings. Intevac’s effective income tax rate is highly dependent on the availability of tax credits and the geographic composition of Intevac’s worldwide earnings.

Intevac enjoys a tax holiday in Singapore through the tax years ending in 2015. The tax holiday provides a lower income tax rate on certain classes of income and the agreement requires that certain thresholds of business investment and employment levels be met in Singapore in order to maintain this holiday.

Intevac is subject to income taxes in the U.S. federal jurisdiction, and various state and foreign jurisdictions. Tax regulations within each jurisdiction are subject to the interpretation of the related tax laws and regulations and require significant judgment to apply. With few exceptions, Intevac is not subject to U.S. federal, state and local, or international jurisdictions income tax examinations by tax authorities for the years before 2006. Tax years 1999 through 2006 are subject to income tax examinations by U.S. federal and California tax authorities to the extent of tax credit carry forwards remaining or utilized in an otherwise open year. During the first quarter of fiscal 2011, the California income tax examination for fiscal years ended 2005, 2006 and 2007 was completed. Due to an income tax refund generated by a carry-back claim, the Internal Revenue Service is currently conducting a review of the Company’s fiscal year 2009 tax return. Additionally, the Singapore Inland Revenue Authority is conducting an examination of the fiscal 2009 tax return of the Company’s wholly-owned subsidiary, Intevac Asia Pte. Ltd. Presently, there are no other active income tax examinations in the jurisdictions where Intevac operates.
