14. |  | Benefit Plans
Pension and other post-retirement plans We sponsor domestic and foreign defined-benefit pension and other post-retirement plans. Pension benefits are based principally on an employee’s years of service and/or compensation levels near retirement. In addition, we provide certain post-retirement health care and life insurance benefits. Generally, the post-retirement health care and life insurance plans require contributions from retirees. In December 2007, we announced that we will be freezing certain U.S. pension plans as of December 31, 2017. Since the announcement, we have pursued a strategy of gradually shifting our U.S. pension asset allocations towards liability hedging assets such as fixed income instruments and away from equity securities. During the last quarter of 2012 we made significant progress in reducing the risk and volatility of our U.S. pension plans by taking the following steps:
| • |  | We paid $331 million to settle pension obligations through a combination of lump sum payments to deferred vested participants and through the purchase of an annuity contract to settle obligations to plan participants in retiree status.
| • |  | We made a special contribution of $190 million to fund our U.S. pension plans.
| • |  | We accelerated our transition to increase the allocations of investments to liability hedging assets.
During the fourth quarter of 2012, we changed our method of recognizing actuarial gains and losses for all of our pension and other post-retirement plans. Historically, we recognized actuarial gains and losses as a component of AOCI in our Consolidated Balance Sheets and amortized them into our Consolidated Statements of Operations and Comprehensive Income (Loss) over the average future service period of the active employees of these plans to the extent such gains and losses were outside of a corridor. We elected to immediately recognize actuarial gains and losses in our Consolidated Statements of Operations and Comprehensive Income (Loss) on the basis that it is preferable to accelerate the recognition of such gains and losses into income rather than to delay such recognition. Additionally, for purposes of calculating the expected return on plan assets, we will no longer use a calculated value for the market-related valuation of plan assets, but instead will use the actual fair value of our plan assets. These changes will improve transparency in our operating results by more quickly recognizing the effects of external conditions on our plan obligations, investments and assumptions. Generally, these gains and losses are measured annually as of December 31 and accordingly will be recorded during the fourth quarter. We have applied these changes retrospectively, adjusting all prior periods (see Note 3).

Assumptions Weighted-average assumptions used to determine benefit obligations as of December 31 were as follows:

Weighted-average assumptions used to determine net periodic benefit cost for years ended December 31 were as follows:

Uncertainty in the securities markets and U.S. economy could result in investment returns less than those assumed. Should the securities markets decline or medical and prescription drug costs increase at a rate greater than assumed, we would expect increasing annual combined net pension and other post-retirement costs for the next several years. Should actual experience differ from actuarial assumptions, the projected pension benefit obligation and net pension cost and accumulated other post-retirement benefit obligation and other post-retirement benefit cost would be affected in future years. Discount rates The discount rate reflects the current rate at which the pension liabilities could be effectively settled at the end of the year based on our December 31 measurement date. The discount rate was determined by matching our expected benefit payments to payments from a stream of bonds rated AA or higher available in the marketplace, adjusted to eliminate the effects of call provisions. This produced a discount rate for our U.S. pension plans of 3.67%, 5.05% and 5.90% in 2012, 2011 and 2010, respectively. The discount rates on our non-U.S. pension plans ranged from 0.50 % to 4.50%, 0.75% to 5.00% and 0.75% to 5.40% in 2012, 2011 and 2010, respectively. There are no other known or anticipated changes in our discount rate assumptions that will impact our pension expense in 2013. Expected rates of return Our expected rates of return on U.S. pension plan assets were 7.5%, 8.0% and 8.5% for 2012, 2011 and 2010, respectively. The expected rate of return is designed to be a long-term assumption that may be subject to considerable year-to-year variance from actual returns. In developing the expected long-term rate of return, we considered our historical returns, with consideration given to forecasted economic conditions, our asset allocations, input from external consultants and broader longer-term market indices. U.S. pension plan assets yielded returns of 10.8%, 7.8% and 11.2% in 2012, 2011 and 2010, respectively. As a result of our de-risking strategy to reduce U.S. pension plan, our expected rate of return on plan assets is 3.75% for 2013. Any difference in the expected rate and actual returns will be included with the actuarial gain or loss recorded in the fourth quarter when our plans are remeasured. Healthcare cost trend rates The assumed healthcare cost trend rates for other post-retirement plans as of December 31 were as follows:
|  | 2012 |  |  | 2011 |
Healthcare cost trend rate assumed for following year |  |  | 7.4 | % |  |  | 7.5 | %
Rate to which the cost trend rate is assumed to decline (the ultimate trend rate) |  |  | 4.5 | % |  |  | 4.5 | %
Year the cost trend rate reaches the ultimate trend rate |  |  | 2027 |  |  |  | 2027 |
The assumed healthcare cost trend rates can have a significant effect on the amounts reported for healthcare plans. A one-percentage-point change in the assumed healthcare cost trend rates would have the following effects as of and for the year ended December 31, 2012:
|  | One Percentage Point |

Pension plans assets Objective The primary objective of our investment strategy is to meet the pension obligation to our employees at a reasonable cost to us. This is primarily accomplished through growth of capital and safety of the funds invested. During 2012, we adopted an investment strategy for our U.S. pension plans with a primary objective of preserving the funded status of the U.S. plans. This is achieved through investments in fixed interest instruments with interest rate sensitivity characteristics closely reflecting the interest rate sensitivity of our benefit obligations. Shifting of allocations away from equities to liability hedging fixed income investments is currently in progress. As equity investments are redeemed, proceeds are reinvested in fixed income instruments. After we have completed the transition, the U.S. pension plans will have in excess of 90 percent allocation to fixed income investments. Asset allocation Our actual overall asset allocation for our U.S. and non-U.S. pension plans as compared to our investment policy goals as of December 31 was as follows:
|  | U.S. pension plans |

While the target allocations do not have a percentage allocated to cash, the plan assets will always include some cash due to cash flow requirements.

Savings plan We have a 401(k) plan (“the 401(k) plan”) with an employee share ownership (“ESOP”) bonus component, which covers certain union and nearly all non-union U.S. employees who meet certain age requirements. Under the 401(k) plan, eligible U.S. employees may voluntarily contribute a percentage of their eligible compensation. We match contributions made by employees who meet certain eligibility and service requirements. Our matching contribution is 100% of eligible employee contributions for the first 1% of eligible compensation and 50% of the next 5% of eligible compensation. In addition to the matching contribution, all employees who meet certain service requirements receive a discretionary ESOP contribution equal to 1.5% of annual eligible compensation. Additionally, we have a 401(k) plan acquired as part of the Merger (“the Flow 401(k) plan”) which covers certain union and all non-union U.S. employees who meet certain age requirements. Under the Flow 401(k) plan, eligible U.S. employees may voluntarily contribute a percentage of their eligible compensation. We match contributions made by employees who meet certain eligibility and service requirements. Our matching contribution is 500% of eligible employee contributions for the first 1% of eligible compensation. Additional company match is based on years of service, as follows: an additional 1% match at 10 – 19 years of service, an additional 2% match at 20 – 24 years, an additional 3% match at 25 – 29 years and an additional 4% match at 30+ years. Participants are 100% vested in the employer match after 3 years of service. Our combined expense for the 401(k) plan, the Flow 401(k) plan and the ESOP was $19.7 million, $15.8 million and $11.0 million in 2012, 2011 and 2010, respectively. Other retirement compensation Total other accrued retirement compensation, primarily related to deferred compensation and supplemental retirement plans, was $52.6 million and $12.6 million as of December 31, 2012 and 2011, respectively, and is included in Pension and other post-retirement compensation and benefits in the Consolidated Balance Sheets. Multi-employer defined benefit plans We participate in a number of multi-employer defined benefit plans on behalf of certain employees. Pension expense related to multi-employer plans was not material in 2012, 2011 and 2010.
