13. Pension plans

ACE provides pension benefits to eligible employees and their dependents through various defined contribution plans and defined benefit plans sponsored by ACE. The defined contribution plans include a capital accumulation plan (401(k)) in the U.S. The defined benefit plans consist of various plans offered in certain jurisdictions outside of the U.S. and Bermuda.

Defined contribution plans (including 401(k))

Under these plans, employees' contributions may be supplemented by ACE matching contributions based on the level of employee contribution. These contributions are invested at the election of each employee in one or more of several investment portfolios offered by a third party investment advisor. Expenses for these plans totaled $96 million, $87 million, and $84 million for the years ended December 31, 2011, 2010, and 2009, respectively.

Defined benefit plans

We maintain non-contributory defined benefit plans that cover certain employees, principally located in Europe and Asia. We do not provide any such plans to U.S.-based employees. We account for pension benefits using the accrual method. Benefits under these plans are based on employees' years of service and compensation during final years of service. All underlying defined benefit plans are subject to periodic actuarial valuation by qualified local actuarial firms using actuarial models in calculating the pension expense and liability for each plan. We use December 31 as the measurement date for our defined benefit pension plans.

At December 31, 2011, the fair value of plan assets and the projected benefit obligation were $434 million and $508 million, respectively. The fair value of plan assets and the projected benefit obligation were $394 million and $487 million, respectively, at December 31, 2010. The accrued pension liability of $74 million at December 31, 2011, and $93 million at December 31, 2010, is included in Accounts payable, accrued expenses, and other liabilities in the consolidated balance sheets.

The defined benefit pension plan contribution for 2012 is expected to be $17 million. The estimated net actuarial loss for the defined benefit pension plans that will be amortized from AOCI into net benefit costs over the next year is $2 million.

Benefit payments were $16 million and $15 million in 2011 and 2010, respectively. Expected future payments are as follows:
