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 establish excess and obsolete inventory reserves based upon historical and anticipated usage. The components of inventories are as follows (in thousands):

    December 31,   June 30,
    2011   2011
Raw materials, net $ 3,543 $ 2,238
Work-in-process   334   277
Finished goods   261   1,332
Total inventories $ 4,138 $ 3,847

 

     As of December 31, 2011 and June 30, 2011, some portion of our inventory was either obsolete or in excess of the current requirements based upon the planned level of sales for future years. Accordingly, we have reduced our gross raw materials inventory by $1,216,000 at December 31, 2011 and $1,176,000 at June 30, 2011 to the estimated net realizable value.
