 : Valued at quoted market prices in an active market on the last business day of the Plan year.

Collective Trusts: Units held in collective trusts (“CT”) are valued using the net asset value practical expedient (“NAV practical expedient”) of the CT as reported by the CT managers. The NAV practical expedient is based on the fair value of the underlying assets owned by the CT, minus its liabilities, and then divided by the number of units outstanding. The beneficial interest in the net assets of each portfolio is represented by units. NAV per unit is determined each business day. Issues and redemptions of units are recorded, upon receipt of unit holder’s instructions in good order, based on the next determined NAV per unit, normally each day. In unusual market conditions, the trustee may in its sole discretion, impose restrictions on issues and redemptions of units. The issuance and redemption provisions of the underlying funds are consistent with those of the portfolios. In certain circumstances units may be purchased or redeemed through the exchange of securities, the fair value of which is used to determine the number of units issued or redeemed.

While the Plan believes its 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.

#### 3. Fair Value Measurements (continued)
In accordance with U.S. GAAP, each of the Plan’s fair value measurements are categorized using a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level l measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are described below:

Level 1 - Inputs to the valuation methodology are unadjusted quoted prices for identical assets or liabilities in active markets that the Plan has the ability to access.

Level 2 - Inputs to the valuation methodology include:

• Quoted prices for similar assets or liabilities in active markets

• Quoted prices for identical or similar assets or liabilities in inactive markets

• Inputs other than quoted prices that are observable for the asset or liability

• Inputs that are derived principally from or corroborated by observable market data by correlation or other means

If the asset or liability has a specified (contractual)
