(1)  Impairment of product licensing rights and other intangibles is stated at gross carrying cost of $131.3 million and $5.2 million less accumulated amortization of $42.8 million and $2.1 million as of the impairment dates. Accordingly, the total net impairment expense was $91.6 million, of which $88.5 million and $3.1 million, were recognized in product licensing rights and other intangibles respectively, for the year ended December 31, 2018.

(2) Differences in the Gross Amounts between periods are due to the write down of fully amortized assets.
