NOTE 4. Inventories

Inventories are summarized as follows:

	December 31, 2011			March 31, 2011
Finished goods	$	875		$	895
Work in process		8,780			6,007
Purchased and manufactured parts		13,839			10,460
		23,494			17,362
Reserve for slow moving and obsolescence		(2,911	)		(2,611	)
Total	$	20,583		$	14,751

Inventory obsolescence is determined by identifying specific items based on the age of inventory and by establishing a general reserve based on annual purchases. Analyzing inventory by age showed little movement once items have aged five years, and historical trends showed that 1.1% of purchases would eventually be scrapped. Accordingly, the Company used these two factors in determining the amount of the reserve.
