Post-Employment and Other Long-Term Employees Benefits

15. 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, 2016, in compliance with U.S. GAAP guidance on determining vested benefit obligations for defined benefit pension plans.

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	2016			2015
Discount rate		2.57	%		3.19	%
Salary increase rate		2.74	%		3.07	%
Expected long-term rate of return on funds for the pension expense of the year		3.57	%		4.44	%

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	2016			2015			2014
Discount rate		3.19	%		3.03	%		3.83	%
Salary increase rate		3.07	%		2.65	%		2.82	%
Expected long-term rate of return on funds for the pension expense of the year		4.44	%		4.76	%		4.88	%

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, 2016 and at December 31, 2015 is as follows:

	Percentage of Plan Assets at December
Asset Category	2016			2015
Cash and cash equivalents		2	%		3	%
Equity securities		29	%		27	%
Government debt securities		3	%		2	%
Corporate debt securities		26	%		26	%
Investments in funds(a)		18	%		19	%
Real estate		2	%		2	%
Other (mainly insurance assets – contracts and reserves)		20	%		21	%
Total		100	%		100	%

(a) Investment in funds are composed approximately for one half of commingled funds mainly invested in corporate bonds for 55%, treasury bonds and notes for 35% and municipal bonds for 5% 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.

As of December 31, 2016, the Company’s plan asset allocation is in line with the target fixed for each plan.

The Company’s detailed pension plan asset allocation including the fair-value measurements of those plan assets as at December 31, 2016 is as follows:

	Total		Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)
Cash and cash equivalents		11		11		—		—
Equity securities		137		6		131		—
Government debt securities		13		12		1		—
Corporate debt securities		125		4		121		—
Investment funds		84		6		78		—
Real estate		12		—		11		1
Other (mainly insurance assets – contracts and reserves)		95		—		—		95
TOTAL		477		39		342		96

The Company’s detailed pension plan asset allocation including the fair-value measurements of those plan assets as at December 31, 2015 is as follows:

	Total		Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)
Cash and cash equivalents		13		13		—		—
Equity securities		128		5		123		—

Other (mainly insurance assets – contracts and reserves)		101		—		—		101
TOTAL		473		37		334		102

The fair value of insurance contracts is based on the value of the assets held by the provider. The approach is consistent with prior years.

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’s contributions to plan assets were $27 million in 2016, $28 million in 2015 and the Company expects to contribute cash of $28 million in 2017.

The Company’s estimated future benefit payments as of December 31, 2016 are as follows:

Years	Pension Benefits		Other Long-term Benefits
2017		36		3
2018		22		3
2019		32		5
2020		29		7
2021		36		3
From 2022 to 2026		233		27

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, 2016 and December 31, 2015. The annual cost of these plans amounted to approximately $70 million in both 2016 and 2015 and $81 million in 2014.
