Post-Employment and Other Long-Term Employees Benefits |
14. |  | POST-EMPLOYMENT AND OTHER LONG-TERM EMPLOYEES BENEFITS
The Company and its subsidiaries have a number of defined benefit pension plans, mainly unfunded, and other long-term employees’ benefits covering employees in various countries. The defined benefit plans provide pension benefits based on years of service and employee compensation levels. The other long-term employees’ plans provide benefits due during the employees’ period of service after certain seniority levels. The Company uses a December 31 measurement date for its plans. Eligibility is generally determined in accordance with local statutory requirements. For Italian termination indemnity plan (“TFR”), generated before July 1, 2007, the Company continues to measure the vested benefits to which Italian employees are entitled as if they left the company immediately as of December 31, 2015, in compliance with U.S. GAAP guidance on determining vested benefit obligations for defined benefit pension plans. The changes in benefit obligation and plan assets were as follows:

The weighted average assumptions used in the determination of the benefit obligation and the plan assets for the pension plans and the other long-term benefits were as follows:
Assumptions |  | 2015 |  |  | 2014 |
Discount rate |  |  | 3.19 | % |  |  | 3.03 | %
Salary increase rate |  |  | 3.07 | % |  |  | 2.65 | %
Expected long-term rate of return on funds for the pension expense of the year |  |  | 4.44 | % |  |  | 4.76 | %
The weighted average assumptions used in the determination of the net periodic benefit cost for the pension plans and the other long-term benefits were as follows:
Assumptions |  | 2015 |  |  | 2014 |  |  | 2013 |
Discount rate |  |  | 3.03 | % |  |  | 3.83 | % |  |  | 3.43 | %
Salary increase rate |  |  | 2.65 | % |  |  | 2.82 | % |  |  | 2.92 | %
Expected long-term rate of return on funds for the pension expense of the year |  |  | 4.76 | % |  |  | 4.88 | % |  |  | 4.43 | %
The discount rate was determined by reference to market yields on high quality long-term corporate bonds applicable to the respective country of each plan, with terms consistent with the term of the benefit obligations concerned. In developing the expected long-term rate of return on assets, the Company modelled the expected long-term rates of return for broad categories of investments held by the plan against a number of various potential economic scenarios. The Company’s pension plan asset allocation at December 31, 2015 and at December 31, 2014 is as follows:
|  | Percentage of Plan Assets at December |
Asset Category |  | 2015 |  |  | 2014 |
Cash |  |  | 3 | % |  |  | 3 | %
Equity securities |  |  | 27 | % |  |  | 28 | %
Bonds securities remunerating interest |  |  | 28 | % |  |  | 28 | %
Real estate |  |  | 2 | % |  |  | 2 | %
Investments in funds(a) |  |  | 19 | % |  |  | 17 | %
Other |  |  | 21 | % |  |  | 22 | %
Total |  |  | 100 | % |  |  | 100 | %
(a) | Investment in funds are composed for one half of commingled funds mainly invested in corporate bonds for 50%, treasury bonds and notes for 42% and municipal bonds for 8% and for the other half of a multi-strategy funds invested in broadly diversified portfolios of corporate and government bonds, equity, fixed income and derivative instruments.

The Company’s investment strategy for its pension plans is to optimize the long-term investment return on plan assets in relation to the liability structure to maintain an acceptable level of risk while minimizing the cost of providing pension benefits and maintaining adequate funding levels in accordance with applicable rules in each jurisdiction. The Company’s practice is to periodically conduct a review in each subsidiary of its asset allocation strategy, in such a way that the asset allocation is in line with the targeted asset allocation with reasonable boundaries. The Company’s asset portfolios are managed in such a way as to achieve adapted diversity and in certain jurisdictions they are entirely managed by the multi-employer funds. The Company does not manage any assets internally. After considering the funded status of the Company’s defined benefit plans, movements in the discount rate, investment performance and related tax consequences, the Company may choose to make contributions to its pension plans in any given year in excess of required amounts. The Company contributions to plan assets were $28 million in both 2015 and 2014 and the Company expects to contribute cash of $28 million in 2016. The Company’s estimated future benefit payments as of December 2015 are as follows:
Years |  | Pension Benefits |  | Other Long-term Benefits
2016 |  | 23 |  | 3
2017 |  | 31 |  | 3
2018 |  | 25 |  | 4
2019 |  | 31 |  | 6
2020 |  | 30 |  | 5
From 2021 to 2025 |  | 234 |  | 24
The Company has certain defined contribution plans, which accrue benefits for employees on a pro-rata basis during their employment period based on their individual salaries. The Company accrued benefits related to defined contribution pension plans of $16 million as of December 31, 2015 and $16 million as of December 31, 2014. The annual cost of these plans amounted to approximately $70 million, $81 million and $89 million in 2015, 2014 and 2013, respectively.
