As part of the Earn-in Right Agreement, Invecture had the right to cause DZ Mexico to acquire certain mill equipment from Vista for $16,000 (the equipment’s then book value) plus certain storage, insurance and transportation costs and any applicable taxes provided that notice of exercise of the right is received by February 7, 2013. During November 2012, Invecture notified us that they would not be exercising this right. As a result, we have written the mill equipment down to its estimated fair value of $10,000, based on an independent assessment from a third party who has been contracted to sell the mill equipment on our behalf. These assets are now classified as assets held for sale.
