Consolidation

Inventories

Substantially all of the Company’s inventories consist of commodities and are classified as finished goods. Inventory balances related to manufacturing operations that include work in process or raw materials that are not considered commodities are not significant.

Readily marketable inventories (“RMI”) include agricultural commodity inventories that are carried at net realizable value, which approximates fair value, based on the commodity nature of the inventories, the availability of observable market prices, and established pricing mechanisms. Net realizable value for RMI is determined based on quoted spot prices on commodity exchanges, adjusted for costs of disposal and transportation applicable to the local market.
