FAIR VALUE MEASUREMENTS. |
The
fair value hierarchy prioritizes the inputs used in valuation techniques into three levels, as follows:
|
● |
Level 1 –
Observable inputs – unadjusted quoted prices in active markets for identical assets and liabilities; |
|
● |
Level 2 –
Observable inputs other than quoted prices included in Level 1 that are observable for the asset or liability through corroboration
with market data; and |
|
● |
Level 3 –
Unobservable inputs – includes amounts derived from valuation models where one or more significant inputs are unobservable.
For fair value measurements using significant unobservable inputs, a description of the inputs and the information used to
develop the inputs is required along with a reconciliation of Level 3 values from the prior reporting period. |
Pooled
separate accounts – Pooled separate accounts invest primarily in domestic and international stocks, commercial paper
or single mutual funds. The net asset value is used as a practical expedient to determine fair value for these accounts. Each
pooled separate account provides for redemptions by the Retirement Plan at reported net asset values per share, with little to
no advance notice requirement, therefore these funds are classified within Level 2 of the valuation hierarchy.
Other
Derivative Instruments – The Company’s other derivative instruments consist of commodity positions. The fair
values of the commodity positions are based on quoted prices on the commodity exchanges and are designated as Level 1 inputs.
