[1] The additions charged to costs and expenses do not include inventory directly written-off that was scrapped during production totaling $0.1 million and $0.2 million for the six months ended June 30, 2013 and 2012, respectively. These amounts are production waste and are not included in management’s reserve for excess and obsolete inventory.

[2] This column represents the reversal of reserves associated with inventory items that were sold during the period. Sell through is the result of differences between our judgment concerning the saleability of inventory items during the excess and obsolete inventory review process and our subsequent experience.
