Valeant Settlement

On October 27, 2017, Valeant, Depomed and the Company entered into a settlement agreement (“Settlement Agreement”) to resolve all matters addressed in the lawsuit. Under the terms of the Settlement Agreement, the litigation will be dismissed, with prejudice, and Valeant will pay to Depomed a one-time, lump-sum payment of $13.0 million. In addition, Depomed and the Company released Valeant and its subsidiary from any and all claims against them as a result of the audit, Valeant’s obligation to pay additional royalties under the commercialization agreement and/or the litigation; and Valeant released Depomed and the Company against any and all claims against them as a result of the audit and/or the litigation. The settlement payment was transferred to PDL from Depomed pursuant to the terms of the Depomed Royalty Agreement, in November of 2017 and has been reflected in the Depomed royalty rights asset discounted cashflow valuation as of September 30, 2017.
