Whenever possible, costs are allocated to each state based on the actual tasked worked (time and
materials). If an activity supports multiple states and fuel types, costs are split between the
states/fuels using an allocation that is based on the proportional efforts of the engagement. When
those splits cannot be further determined, the Company allocates based on a 70%/30% split for
Washington/Idaho.
