NOTE B – INTANGIBLE ASSETS

Intangible assets consist of the following:

Intellectual property consists of technology for producing targeted proteins in plants for the development and manufacture of novel vaccines and therapeutics for humans and also certain novel product compositions and uses. The Company accounts for intangible assets at their historical cost and records amortization utilizing the straight-line method based upon their estimated useful lives. Intellectual property is amortized over a period from eighteen to twenty-three years and patents over ten years. The Company reviews the carrying value of its intangible assets for impairment whenever events or changes in business circumstances indicate the carrying amount of such assets may not be fully recoverable. Evaluating for impairment requires judgment, including the estimation of future cash flows, future growth rates and profitability and the expected life over which cash flows will occur. Changes in the Company’s business strategy or adverse changes in market conditions could impact impairment analyses and require the recognition of an impairment charge equal to the excess of the carrying value over its estimated fair value. There was no impairment during the three and nine months ended March 31, 2012.

Amortization expense for intangible assets is recorded utilizing the straight-line method, was included in general and administrative expenses, and approximated $81,000 and $95,000, for the three months ended March 31, 2012 and 2011, respectively. Amortization expense for the nine months ended March 31, 2012 and 2011 was approximately $240,000 and $281,000 respectively.
