(1)

The Company does not control the investment mix or strategy of the pooled funds. The pooled funds guarantee a minimum rate of return. If actual investment returns are less than the guarantee minimum rate, then the provider’s statutory reserves are used to top up the shortfall. The pooled funds primarily invest in hold to maturity bonds, real estate and other fixed income investments, which are expected to provide a stable rate of return.

(2)	The mutual funds primary aim is to provide investors with an exposure to a diversified mix of predominantly growth oriented assets (70%) with moderate to high volatility and some defensive assets (30%).

Schedule of Assumptions Used

The weighted average assumptions used to determine benefit obligations at December 31, 2015 and 2014 were as follows:


	December 31, 2015	December 31, 2014
Discount rates	3.0%	2.9%
Rate of compensation increase	3.4%	4.2%

The weighted average assumptions used to determine net pension expense for the years ended December 31, 2015, 2014 and 2013 were as follows:


	Year Ended December 31, 2015 $	Year Ended December 31, 2014 $	Year Ended December 31, 2013 $
Discount rates	3.0%	2.9%	3.9%
Rate of compensation increase	3.4%	4.2%	4.7%
Expected long-term rates of return ⁽¹⁾	4.0%	4.0%	4.8%

(1)

To the extent the expected return on plan assets varies from the actual return, an actuarial gain or loss results. The expected long-term rates of return on plan assets are based on the estimated weighted-average long-term returns of major asset classes. In determining asset class returns, the Company takes into account long-term returns of major asset classes, historical performance of plan assets, as well as the current interest rate environment. The asset class returns are weighted based on the target asset allocations.
