WMIH agreed to cause WMMRC, while the Runoff Notes were outstanding, to deposit all distributions, dividends or other receipts in respect of Runoff Proceeds Distributions (as defined in the Indentures) on the date paid to WMIH in the Collateral Account established in accordance with the terms of the Indentures. On any interest payment date, payments were made from the Collateral Account and from any other Runoff Proceeds Distributions in the priority set forth in the Indentures. In connection with certain interest payments due and payable in respect of the First and Second Lien Notes, WMIH elected, consistent with the terms of the Indentures, to issue payment-in-kind notes in lieu of making such interest payments in cash when no cash was available. As of April 15, 2015, the First Lien Notes were fully redeemed by the Company, and on April 27, 2015, the First Lien Indenture was satisfied and discharged. As of September 29, 2017, the Second Lien Notes were fully redeemed by the Company, and on October 2, 2017, the Second Lien Indenture was satisfied and discharged. As a result of the satisfaction and discharge of the Second Lien Indenture the Collateral Account was subsequently closed and the remaining funds transferred to cash and cash equivalents to be used for general corporate purposes. As of December 31, 2016, the Collateral Account contained $0.4 million of cash received from WMMRC which was ultimately used for future administrative expenses, interest and principal payments on the Runoff Notes. Second Lien Note principal outstanding totaled zero and approximately $18.8 million as of December 31, 2017 and 2016, respectively. Approximately $18.8 million and $2.9 million of Runoff Notes principal was paid during the years ended December 31, 2017 and 2016, respectively.
