Accounts payable and other accrued expenses includes $402,651 relating to a one-time warranty issue experienced on three customers’ projects. The expenses related to parts and labor to repair units that had been delivered to these customers prior to year-end. Since the issue is limited to these three projects and is not anticipated to reoccur in the future, we have made no adjustment to the ongoing 1% warranty reserve that we accrue on all sales.
