Pension And Other Postretirement Benefits Disclosure [Abstract]

10. Pension Plans

We maintain three defined benefit pension plans: one for United Kingdom employees, one for German employees, and one for Philippine employees. These plans cover most of the employees in the United Kingdom, Germany and the Philippines. Benefits are based on years of service and the employees' compensation. We deposit funds for these plans, consistent with the requirements of local law, with investment management companies, insurance companies, banks or trustees and/or accrue for the unfunded portion of the obligations. The measurement date for the projected benefit obligations and the plan assets is March 31. The United Kingdom and German plans have been curtailed. As such, the plans are closed to new entrants and no credit is provided for additional periods of service. The German plan was held by a separate legal entity. As of December 31, 2011, the German defined benefit plan was completely unfunded. We expect to contribute approximately $705,000 to the United Kingdom plan in the fiscal year ending March 31, 2012. This contribution is primarily contractual.

In connection with the Zilog acquisition in February 2010, we assumed the defined benefit plan for the local employees of Zilog's Philippine subsidiary. As of December 31, 2011, the pension plan was overfunded by approximately $327,000. The overfunding was included under “Other assets” on our unaudited condensed consolidated balance sheets.

The net periodic pension expense includes the following components (in thousands):

	Three Months Ended				Nine Months Ended
