The Company's assets included restricted cash, which was pledged to support bank guarantees for product warranty of product delivered on a sales contract in the quarter ended March 31, 2011. The current portion covered the first year of product warranty, and the noncurrent portion was recently issued and will be renewed annually for seven years to cover each year of the extended warranty and maintenance agreement.

These assets are carried at cost, which approximates market value.
