The non-current portion of inventories represents that portion of the inventories in excess of amounts expected to be sold or used in the next twelve months. The non-current inventories are primarily comprised of repair parts for older generation products that are still in operation, but are not technologically compatible with current product configurations. The weighted average age of the non-current portion of inventories on hand as of September 30, 2012 is 1.2 years. The Company expects to use the non-current portion of the inventories on hand as of September 30, 2012, over the periods presented in the following table:
