Each quarter, the Company reviews the ongoing value of its capitalized patent costs. In the first nine months of fiscal 2012 and 2011, some of these assets were identified as being associated with patents no longer consistent with the Company’s business strategy. As a result of this review, the Company recorded a loss as shown above from the impairment of patents that were previously capitalized.
