5. Inventories

     Inventories are stated at the lower of cost or market, with cost being determined by using the first-in, first-out method. We reduce our excess and obsolete inventory to market value, if below cost, based upon historical and anticipated usage. The components of inventories are as follows (in thousands):

    March 31,   June 30,
    2013   2012
Raw materials $ 1,695 $ 2,736
Work-in-process   304   309
Finished goods   950   638
Total inventory $ 2,949 $ 3,683
