[1] Other consists primarily of accelerated depreciation on certain assets in our Salt Lake manufacturing facility. The company completed the closure of the 8 inch line at this facility as of Q4'13. The equipment is in the process of being transferred to other Fairchild locations. The depreciation that relates to the initial installation cost of this equipment has been accelerated as these costs are specific to its installation in Salt Lake. The depreciation was accelerated over an 11 month time period.
