In a power point presentation, Chairman Dunevant challenged the numbers released by Alcoa last week as to their options on the table, particularly the $1.2 million financial guarantee from Alcoa to Stanly County should the 450 Clean Tech jobs not materialize. Dunevant pressed the value of this guarantee over the life of the 50-year license, asserting that Alcoa had not factored in depreciation. Dunevant contended that due to inflation that amount would be worth only $500,000 by the year 2020 and just $188,000 at the end of 50 years when the license would again be up for renewal.
