Notes to Financial Statements
Subsequent Events [Text Block]	12.          Subsequent Event In August 2016, the Board of Directors determined that RES-440, a “soft” anti-androgen compound for the treatment of acne vulgaris, was outside the Company’s core product focus, is not a priority and therefore will be abandoned and written off in the third quarter of 2016. The abandonment will result in a $932,000 charge to earnings to reduce the carrying amount of the RES-440 IPR&D asset and will also result in a reduction of the associated deferred tax liability.
