[1] | Level 1 investments represent mutual funds for which a quoted market price is available on an active market. These investments primarily hold stocks or bonds, or a combination of stocks and bonds. | |
[2] | Level 2 inputs are inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. The Company's pension plan financial assets held in the Adept Strategy 9 Fund and the Schroder investments are Level 2 assets. The Company uses the Net Asset Value to determine the fair value of underlying investments which (a) do not have readily determinable fair value; and (b) prepare their financial statements consistent with the measurement principles of an investment company. The Funds are not exchange traded. The Funds are not subject to any redemption notice periods or restrictions and can be redeemed on a daily basis. No gates or holdbacks or dealing suspensions are being applied to the Funds. The Funds are of perpetual duration. | |
[3] | The Company currently does not have any Level 3 pension plan financial assets. | |
