The Company expects to contribute approximately $0.4 million to the plans in 2017. The Company's pension plan weighted asset allocations by asset category are as follows:
| December 31
| 2016 |  | 2015
Asset Category |  |  |
Pooled Funds: |  |  |
Canadian equities | 11.7 | % |  | 23.0 | %
U.S. equities | 4.6 | % |  | 14.0 | %
Non-North American equities | 21.6 | % |  | 18.6 | %

The Plan's long-term overall objective is to maintain benefits at their current level without affecting the cost of maintaining the Plan, assuming that the demographic make-up of the group of members remains the same. The primary investment objective, in support of the overall objective, is to earn the highest rate of return possible for the Plan, while keeping risk at acceptable levels. The long-term return objective of the Plan is to achieve a minimum annualized rate of return in excess of the actuarial requirements. This translates into a required return of 3.0% above inflation, net of investment management fees. The return objective is consistent with the overall investment risk level that the Plan assumes in order to meet the pension obligations of the Plan. To achieve this long term investment objective, the Plan has adopted an asset mix that has a combination of equity and fixed income investments. Risk is controlled by investing in a well-diversified portfolio of asset classes. A benchmark portfolio is established based on the expected returns for each asset class available. The investment of the Plan's assets in accordance with the benchmark portfolio should enable the Plan to not only attain, but also exceed the minimum overall objective. The following table presents the target asset mix based on market value for each investment category within which the investment managers must invest the Plan's assets. The asset mix is reviewed and rebalanced to target on an annual basis.
Asset Category | Target %
Canadian equities | 12.5 | %
Non-Canadian equities | 27.5 | %
Total equities | 40 | %
Fixed income investments | 45 | %
Other investments | 15 | %
The Plan's assets are measured at fair value, which is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. As described in Note 2, "Accounting Policies," financial assets and liabilities are classified in the fair value hierarchy based on the lowest level of any input that is significant to the measurement of fair value. Investments for which fair value is measured using the NAV per share practical expedient are not classified in the fair value hierarchy. The following describes the valuation methodologies used to measure the fair value of the Plan's assets. Pooled Equity Investments. These investments consist of the Plan's share of segregated funds that invest primarily in equity securities. The funds are valued at the net asset value of shares held at December 31. Pooled Fixed Income Investments. These investments consist of a segregated fund that primarily invests in Canadian issued bonds and debentures and is valued at the net asset value of shares held in the underlying funds. Other Investments. These investments consist of money market and diversified growth funds. The diversified growth fund invests in a broad range of asset classes, including equities, bonds, infrastructure, property, commodities and absolute return strategies. These investments are valued at the net asset value of shares held in the underlying funds. The fair value methods described above may not be indicative of net realizable value or reflective of future fair values. Additionally, while the Company believes the valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting date. The following tables set forth the fair value of plan assets by asset category:
