25.RETIREMENT AND POSTRETIREMENT BENEFITS

PENSION PLANS

The Company has three registered pension plans which provide either defined benefit or defined contribution pension benefits, or both, to employees of the Company. The Canadian Plans provide Company funded defined benefit pension and/or defined contribution benefits to Canadian employees of Enbridge. The United States Plan provides Company funded defined benefit pension benefits for United States based employees. The Company has four supplemental pension plans that provide pension benefits in excess of the basic plans for certain employees.

A measurement date of December 31, 2014 was used to determine the plan assets and accrued benefit obligation for the Canadian and United States plans.

Defined Benefit Plans

Benefits payable from the defined benefit plans are based on members’ years of service and final average remuneration. These benefits are partially inflation indexed after a member’s retirement. In 2014, the mortality assumption was revised for the United States Plan resulting in an increase to pension liabilities of $21 million. In 2013, the mortality assumptions were revised for the Canadian Plans, resulting in an increase to pension liabilities of $58 million. Contributions by the Company are made in accordance with independent actuarial valuations and are invested primarily in publicly-traded equity and fixed income securities. The effective dates of the most recent actuarial valuations and the next required actuarial valuations for the basic plans are as follows:

	Effective Date of Most Recently Filed Actuarial Valuation	Effective Date of Next Required Actuarial Valuation
Canadian Plans
Liquids Pipelines	December 31, 2013	December 31, 2014
Gas Distribution	December 31, 2013	December 31, 2016
United States Plan	January 1, 2014	January 1, 2015

Defined Contribution Plans

Contributions are generally based on the employee’s age, years of service and remuneration. For defined contribution plans, benefit costs equal amounts required to be contributed by the Company.

OTHER POSTRETIREMENT BENEFITS

OPEB primarily includes supplemental health and dental, health spending accounts and life insurance coverage for qualifying retired employees.

BENEFIT OBLIGATIONS AND FUNDED STATUS

The following tables detail the changes in the benefit obligation, the fair value of plan assets and the recorded asset or liability for the Company’s defined benefit pension plans and OPEB plans using the accrual method.

Assets of $32 million (2013 - $27 million) are held by the Company in trust accounts that back non-registered supplemental pension plans benefitting United States plan participants. Due to United States tax regulations, these assets are not restricted from creditors, and therefore the Company is unable to include these balances in plan assets for accounting purposes. However, these assets are committed for the future settlement of non-registered supplemental pension plan obligations included in the underfunded status as at the end of the year.

The weighted average assumptions made in the measurement of the projected benefit obligations of the pension plans and OPEB are as follows:

	Pension			OPEB
Year ended December 31,	2014	2013	2012	2014	2013	2012
Discount rate	4.0%	5.0%	4.2%	3.9%	4.9%	4.0%
Average rate of salary increases	4.0%	3.7%	3.7%

Total amount recognized in Comprehensive income	342	(22)	164	30	(25)	27

Unamortized actuarial losses included in AOCI, before tax, were $489 million (2013 - $246 million) relating to the pension plans and $26 million (2013 - $11 million) relating to OPEB at December 31, 2014.

Unamortized prior service costs included in AOCI, before tax, were $6 million (2013 - $6 million) relating to OPEB at December 31, 2014.

The Company estimates that approximately $28 million related to pension plans and $1 million related to OPEB at December 31, 2014 will be reclassified from AOCI into earnings in the next 12 months.

Regulatory adjustments are recorded in the Consolidated Statements of Earnings, the Consolidated Statements of Comprehensive Income and the Consolidated Statements of Financial Position to reflect the difference between pension expense for accounting purposes and pension expense for ratemaking purposes. Offsetting regulatory assets or liabilities are recorded to the extent pension or OPEB costs or gains are expected to be collected from or refunded to customers in future rates (Note 5). For the year ended December 31, 2014, an offsetting regulatory liability of $3 million (2013 - $3 million regulatory asset) has been recorded to the extent pension and OPEB costs are expected to be collected from customers in future rates.

The weighted average assumptions made in the measurement of the cost of the pension plans and OPEB are as follows:

	Pension			OPEB
Year ended December 31,	2014	2013	2012	2014	2013	2012
Discount rate	5.0%	4.2%	4.5%	4.9%	4.0%	4.4%
Average rate of return on plan assets	6.7%	6.7%	7.1%	6.0%	6.0%	6.0%
Average rate of salary increases	3.7%	3.7%	3.5%

MEDICAL COST TRENDS

The assumed rates for the next year used to measure the expected cost of benefits are as follows:

	Medical Cost Trend Rate Assumption for Next Fiscal Year	Ultimate Medical Cost Trend Rate Assumption	Year in which Ultimate Medical Cost Trend Rate Assumption is Achieved
Canadian Plans
Drugs	8.0%	4.4%	2029
Other Medical	4.5%	-	-
United States Plan	7.2%	4.5%	2030

A 1% increase in the assumed medical care trend rate would result in an increase of $37 million in the benefit obligation and an increase of $2 million in benefit and interest costs. A 1% decrease in the assumed medical care trend rate would result in a decrease of $32 million in the benefit obligation and a decrease of $2 million in benefit and interest costs.

PLAN ASSETS

The Company manages the investment risk of its pension funds by setting a long-term asset mix policy for each plan after consideration of: (i) the nature of pension plan liabilities; (ii) the investment horizon of the plan; (iii) the going concern and solvency funded status and cash flow requirements of the plan; (iv) the operating environment and financial situation of the Company and its ability to withstand fluctuations in pension contributions; and (v) the future economic and capital markets outlook with respect to investment returns, volatility of returns and correlation between assets. The overall expected rate of return is based on the asset allocation targets with estimates for returns on equity and debt securities based on long-term expectations.

Expected Rate of Return on Plan Assets

Major Categories of Plan Assets

Plan assets are invested primarily in readily marketable investments with constraints on the credit quality of fixed income securities. As at December 31, 2014, the pension assets were invested 57.0% (2013 - 58.0%) in equity securities, 32.2% (2013 - 31.0%) in fixed income securities and 10.8% (2013 - 11.0%) in other. The OPEB assets were invested 58.8% (2013 - 59.3%) in equity securities, 40.2% (2013 - 38.3%) in fixed income securities and 1.0% (2013 - 2.4%) in other.

The following table summarizes the Company’s pension financial instruments at fair value. Non-financial instruments with a carrying value of $4 million asset (2013 - $1 million asset) and refundable tax assets of $96 million (2013 - $85 million) have been excluded from the table below.
