Subsequent Events	21. Subsequent Events The legal final maturity date of the Securitization Notes is in January of 2043. As the Company did not repay or refinance the Securitization Notes prior to January 2020 (the “anticipated repayment date”), additional interest will accrue on amounts outstanding under the Securitization Notes. This additional interest is not required to be paid until 2043 and does not compound annually. Beginning in January 2020, the Company will not be required to make $42.7 million of contractual principal payments referred to in Note 8 of the consolidated financial statements. Future principal payments will be formulaically based on a percentage of receipts of royalty revenue. In March 2020, the World Health Organization recognized the novel strain of coronavirus, COVID-19, as a pandemic. This coronavirus outbreak has severely restricted the level of economic activity around the world. In response to this coronavirus outbreak, the governments of many countries, states, cities and other geographic regions have taken preventative or protective actions, such as imposing restrictions on travel and business operations and advising or requiring individuals to limit or forego their time outside of their homes. Temporary closures of businesses have been ordered and numerous other businesses have temporarily closed voluntarily. The Company cannot reasonably estimate the negative impact to the Company's business, revenues, financial condition or results of operations. On March 30, 2020, the Company entered into the fifth amendment and waiver to the Senior Secured Term Loan (the “Fifth Amendment”). The Fifth Amendment, among other things, (i) waived an event of default under the Senior Secured Term Loan due to the Company’s receipt of a going concern qualified audit opinion and (ii) modified the asset sale prepayment obligation to obligate the Company to pay 75% of the net proceeds from one or more asset sales in any fiscal year to the extent the aggregate amount of asset sale net proceeds exceed $5.0 million.
