a) Defined Benefit Pension Plans We have qualified defined benefit pension plans that cover certain of our former United States and Canadian employees and provide benefits based on an employee’s years of service. The plans operate under similar regulatory frameworks and generally face similar risks. The majority of benefit payments are from trustee-administered funds; however, there are also a number of unfunded plans where the Company meets the benefit payment obligation as it falls due. Plan assets held in trust are governed by local regulations and practice in each country. Responsibility for governance of the plans - overseeing all aspects of the plans including investment decisions and contribution schedules - lies with the Company. We have set up pension committees to assist in the management of the plans and have also appointed experienced independent professional experts such as actuaries, custodians and trustees. The significant actuarial assumptions were as follows:
As at December 31 | Pension Plans 2017 | Other Post-Retirement Benefits 2017 |  | Pension Plans 2016 | Other Post-Retirement Benefits 2016 |
Discount rate | 2.90-3.95% | 3.75 | % | 2.10-3.90% | 3.70 | %
b) Other Post-Retirement Benefits We provide post-retirement medical, dental, and life insurance benefits to certain employees in the US. All of these plans are unfunded. The weighted average duration of the defined benefit obligation is 10 years (2016: 10 years).
| Less than a year |  | Between 1-2 years |  | Between 2-5 years |  | Over 5 years |  | Total |
Pension benefits |  | $18 |  |  | $19 |  |  | $54 |  |  | $313 |  |  | $404 |
Other post-retirement benefits | 1 |  | 1 |  | 2 |  | 6 |  | 10 |
At December 31, 2016 |  | $19 |  |  | $20 |  |  | $56 |  |  | $319 |  |  | $414 |
Pension benefits | 14 |  | 14 |  | 39 |  | 200 |  | 267 |
Other post-retirement benefits | 1 |  | 1 |  | 2 |  | 5 |  | 9 |
At December 31, 2017 |  | $15 |  |  | $15 |  |  | $41 |  |  | $205 |  |  | $276 |
c) Defined Contribution Pension Plans Certain employees take part in defined contribution employee benefit plans and we also have a retirement plan for certain officers of the Company. Our share of contributions to these plans, which is expensed in the year it is earned by the employee, was $33 million in 2017 (2016: $32 million).
