Jacobs sells to manufacturers of products that will pay a premium for foam insulators with these properties. All of Jacobs' customers purchase the foam chemical as a substitute for competitors' products. If Jacobs cannot meet the order when it is received, the customer makes its purchase from a competitor without any loss of future demand.

Jacobs will eventually migrate to a new technology using a different supply chain network. This new foam technology will render the current technology obsolete. Factories producing the new foam will come online on day 1460. All customers are aware of the pending new technology and, as a result, demand will decrease linearly beginning at day 1430, reaching 0 on day 1460.
