The expected return on plan assets is determined based on the market-related value of plan assets of $2,153 million as at January 1, 2017 (2016 – $1,180 million), adjusted for interest on certa in cash flows during the year. The market-related value of assets is based on a five-year smoothed asset value. Any investment gains (or losses) in excess of (or less than) the expected return on plan assets are recognized on a straight-line basis into the market-related value of asset s over a five-year period. Pension Plan Asset Allocations Emera’s investment policy includes discussion regarding the investment philosophy, the level of risk which the Company is prepared to accept with respect to the investment of the Pension Funds, and the basis for measuring the performance of the assets. Central to the policy is the target asset allocation by major asset categories. The objective of the target asset allocation is to diversify risk and to achieve asset returns that meet or exceed the plan’s actuarial assumpt ions. The diversification of assets reduces the inherent risk in financial markets by requiring that assets be spread out amongst various asset classes. Within each asset class, a further diversification is undertaken through the investment in a broad bas ket of investment and non-investme nt grade securities. Emera’s target asset allocation is as follows:
Canadian Pension Plans |  |  |  |
Asset Class | Target Range at Market
Short-term securities |  | 0% | to | 5%
Fixed income |  | 35% | to | 50%
Equities: |  |  |  |
Canadian |  | 12% | to | 22%
Non-Canadian |  | 30% | to | 55%
Non-Canadian Pension Plans |  |  |  |
Asset Class | Target Range at Market Weighted average
Short-term securities |  | 47% | to | 52%
Equities |  | 48% | to | 53%
Pension Plan assets are overseen by the respective Management Pension Committees in the sponsoring companies. All pension investments are in accordance with policies approved by the respective Board of Directors of each sponsoring company. The following tables set out the classification of the methodology used by the Company to fair value its investments:

(1) NAV investments are open-ended registered and non-registered mutual funds, collective investment trusts, or pooled funds. NAV’s are calculated daily and the funds honor subscription and redemption activity regularly.
(2) The common collective trusts are private funds valued at NAV. The NAVs are calculated based on bid prices of the underlying securities. Since the prices are not published to external sources, NAV is used as a practical expedient. Certain funds invest primarily in equity securities of domestic and foreign issuers while others invest in long duration U.S. investment grade fixed income assets and seeks to increase return through active management of interest rate and credit risks. The funds honor subscription and redemption activity regularly.

Canadian Post-Retirement Benefit Plans There are no assets set aside to pay for the Canadian post-retirement benefit plans. As is common in Canada, post-retirement health benefits are paid from general accounts as required. US Post-Retirement Benefit Plans Emera’s US subsidiaries currently provide certain post-retirement health care and life insurance benefits for employees retiring after age 5 0 who meet eligibility requirements. Post-retirement benefit levels are substanti ally unrelated to salary. The C ompany reserves the right to termina te or modify plans in whole or in part at any time. Emera Maine provides retiree medical benefits to certain groups of employees. The Company's retiree medical expenses are incorporated into rate filings with its regulators and are recovered through its electric rates to customers. TECO Energy and NMGC offers retirees under age 65 and their dependents a self-funded HRA medical plan identical to that offered to active TECO Energy employees. TECO Energy retirees over the age of 65 are enrolled in a Medicare Advantage plan. NMGC retirees over age 65 and their dependents receive a fixed subsidy with which they can purchase additional coverage through a medical supplement program. NMGC also provides dental benefits to retirees and spouses.

Refer to n ote 15 for more information on the fair value hierarchy and inputs used to measure fair value. Investments in Emera As at December 31, 2017 and 2016, the assets related to the pension funds and post-retirement benefit plans do not hold any material investments in Emera or its subsidiaries securities. However, as a significant portion of assets for the benefit plan are held in pooled assets, there may be indirect investments in these securities. Cash Flows The following table shows the expected cash flows for defined benefit pension and other post-retirement benefit plans:
millions of Canadian dollars | Defined benefit pension plans | Non-pension benefit plans
Expected employer contributions |  |  |  |
2018 | $ | 97 | $ | 25
Expected benefit payments |  |  |  |
2018 |  | 147 |  | 22

Assumptions |  |  |  |  |  |  |  |
The following table shows the assumptions that have been used in accounting for defined benefit pension and other post-retirement benefit plans: |
| 2017 | 2016
(weighted average assumptions) | Defined benefit pension plans | Non-pension benefit plans | Defined benefit pension plans | Non-pension benefit plans
Benefit obligation – December 31: |  |  |  |  |  |  |  |
Discount rate | 3.55 | % | 3.65 | % | 3.96 | % | 4.18 | %
Rate of compensation increase | 3.12 | % | 3.28 | % | 2.82 | % | 2.54 | %
Health care trend - initial (next year) | - |  | 6.65 | % | - |  | 6.78 | %
- ultimate | - |  | 4.45 | % | - |  | 4.45 | %
- year ultimate reached | - |  | 2036 |  | - |  | 2035 |
Benefit cost for year ended December 31: |  |  |  |  |  |  |  |
Discount rate | 3.96 | % | 4.18 | % | 3.79 | % | 3.88 | %
Expected long-term return on plan assets | 6.29 | % | 6.08 | % | 6.33 | % | 4.43 | %
Rate of compensation increase | 2.82 | % | 2.54 | % | 2.88 | % | 2.56 | %
Health care trend - initial (current year) | - |  | 6.78 | % | - |  | 6.76 | %
- ultimate | - |  | 4.45 | % | - |  | 4.45 | %
- year ultimate reached | - |  | 2035 |  | - |  | 2020 |
Figures shown are weighted averages. Actual assumptions used differ by plan.
The expected long-term rate of return on plan assets is based on historical and projected real rates of return for the plan’s current asset allocation, and assumed inflation. A real rate of return is determined for each asset class. Based on the asset allocation, an overall expected real rate of return for all assets is determined. The asset return assumption is equal to the overall real rate of return assumption added to the inflation assumption, adjusted for assumed expenses to be paid from the plan. The discount rate is based on high-quality long-term corporate bonds, with maturities matching the estimated cash flows from the pension plan Sensitivity Analysis for Non-Pension Benefits Plans The health care cost trend significantly influences the am ounts presented for health care plans. An increase or decrease of one percentage point of the assumed health care cost trend would have had the following impact in 2017:
millions of Canadian dollars | Increase | Decrease
Service cost and interest cost | $ | 1 | $ | (1)
Accumulated post-retirement benefit obligation, December 31 |  | 19 |  | (16)
Sensitivity Analysis for Defined Benefit Pension Plans The impact on the 2017 benefit cost of a 25 basis point change in the discount rate and asset return assumptions is as follows:
millions of Canadian dollars | Increase | Decrease
Discount rate assumption | $ | (9) | $ | 9
Asset rate assumption |  | (6) |  | 6
Amounts to be Amortized in the Next Fiscal Year
The following table shows the amounts from the AOCL and regulatory assets, which are expected to be recognized as part of the net periodic benefit cost in fiscal 2018:
|  | 2018
millions of Canadian dollars | Defined benefit pension plans | Non-pension benefit plans
Actuarial gains (losses) | $ | (36) | $ | (2)
Past service gains |  | 1 |  | 6
Regulatory assets |  | (21) |  | (2)
Total | $ | (56) | $ | 2
Defined Contribution Plan Emera also provides a defined contribution pension plan for certain employees. The Company’s contribution for the year ended December 31, 2017 was $23 million (2016 – $17 million), with the increase due to TECO Energy contributions being included for the full year.
