Alabama. Dixon‚ a specialty chemicals company‚ was willing to purchase the aforementioned plant for $12m with the option to invest a further $2.25m on laminate technology. The subsequent investment in Laminate technology was expected to eliminate graphite costs and reduce power consumption at the Collinsville plant by 15% to 20%. We will evaluate the acquisition of the Collinsville by Dixon at the proposed price. Table 1 identifies the assumptions that have been used for the evaluation of this
