Employee Benefit Plans | 12 Months Ended

Dec. 31, 2011
Employee Benefit Plans | 9. Employee Benefit Plans The Company maintains a pension plan in the United Kingdom that consists of two components: the Final Salary Plan (the “U.K. Plan”), which is a defined benefit plan, and the Retirement Savings Plan, which is a defined contribution plan. In 1997, membership to the U.K. Plan was closed and in 2003 the Company was allowed to stop accruing additional benefits to the participants. Benefits under the U.K. Plan were based on the employees’ years of service and compensation. Most of the beneficiaries of this plan are no longer employed by the Company. The Company also maintains a tax qualified pension plan in Japan (the “Japan Plan”) that covers certain of the Company’s Japanese employees. Benefits are based on years of service and compensation at retirement. Employees with less than twenty years of service to the Company receive a lump sum benefit payout. Employees with twenty or more years of service to the Company receive a benefit that is guaranteed for a certain number of years. Participants may, under certain circumstances, receive a benefit upon termination of employment. Pension and other benefit costs reflected in the accompanying consolidated statements of operations are based on a projected benefit method of valuation. The funded status of pension plan liabilities are included in accrued pension liabilities in the accompanying consolidated balance sheets. The Company continues to fund each plan sufficient to meet current benefits as well as fund a portion of future benefits as permitted by regulatory authorities. The net periodic pension cost for the U.K. Plan and the Japan Plan includes the following components (in thousands):

The actuarial assumptions used to compute the net periodic pension cost for the U.K. Plan and the Japan Plan were as follows:
|  | U.K. Plan |  |  | Japan Plan |
|  | 2011 |  |  | 2010 |  |  | 2009 |  |  | 2011 |  |  | 2010 |  |  | 2009 |

The actuarial assumptions used to compute the funded status for the U.K. Plan and the Japan Plan were as follows:
|  | U.K. Plan |  |  | Japan Plan |
|  | 2011 |  |  | 2010 |  |  | 2011 |  |  | 2010 |
Weighted-average discount rate |  |  | 4.9 | % |  |  | 5.3 | % |  |  | 1.2 | % |  |  | 1.3 | %

Rate of inflation |  |  | 2.2 | % |  |  | 3.2 | % |  |  | — |  |  |  | — |
The discount rates used are derived on (AA) corporate bonds that have a maturity approximating the terms of the related obligations. In estimating the expected return on plan assets, the Company considered the historical performance of the major asset classes held, or anticipated to be held, by the applicable pension plans and current forecasts of future rates of return for these asset classes. The following table provides a reconciliation of benefit obligations and plan assets of the U.K. Plan and the Japan Plan (in thousands):

|  | U.K. Plan |  |  | Japan Plan |
2012 |  | $ | 458 |  |  | $ | 197 |

In the U.K., funding valuations are conducted every three years in order to determine the future level of contributions. The Company’s latest funding valuation was completed in October 2010. Based on the results of the valuation, the Company increased its annual contributions to the U.K. Plan from approximately $0.6 million to $0.8 million for a period of 10 years and 5 months beginning September 2010, including an additional one-time lump-sum payment of approximately $1.6 million which was paid in 2010. The Company anticipates that contributions for 2012 will be $0.8 million for the U.K. Plan and $0.4 million for the Japan Plan. Fair Value of Plan Assets In the U.K., the Company’s overall objective is to invest plan assets in a portfolio of diversified assets, primarily through the use of institutional collective funds, to achieve long-term growth. The strategic asset allocation uses a combination of risk controlled and index strategies in fixed income and global equities. The target allocations are approximately 50% to funds investing in global equities, approximately 30% to funds investing in global bonds, approximately 16% to alternative assets (including commodities, private equity and debt, real estate, infrastructure, hedge funds and currency funds), and approximately 4% in cash. In Japan, the investment strategy is primarily focused on the preservation of principal invested in insurance contracts. The following table summarizes the fair values of the Company’s plan assets as of December 31, 2011 (in thousands):

The tables above present the fair value of plan assets in accordance with the fair value hierarchy. Certain pension plan assets are measured using net asset value per share (or its equivalent) and are reported as a level 2 investment above due to the Company’s ability to redeem its investments either at the balance sheet date or within limited time restrictions. Defined Contribution Plans The Company has defined contribution employee savings plans in the U.K. and the U.S. The Company matches the contributions of participating employees on the basis of percentages specified in each plan. Company matching contributions to the plans were $2.0 million, $1.6 million and $1.6 million in 2011, 2010 and 2009, respectively.
