The net proceeds from the sale of the New Notes were $1.190 billion, after deducting the initial purchaser’s discount and commission and estimated fees and expenses related to the offering. These proceeds were used to redeem all of the Issuer's outstanding senior unsecured notes due 2017, including accrued interest. Interest on the New Notes are payable on February 1 and August 1 of each year, commencing August 1, 2017. The Issuers issued the New Notes under an indenture dated January 18, 2017, among the Issuers, Icahn Enterprises Holdings (the "Guarantor"), and Wilmington Trust Company, as trustee. The indenture contains customary events of defaults and covenants relating to, among other things, the incurrence of debt, affiliate transactions, liens and restricted payments. Prior to maturity of the New Notes, the Issuers may redeem some or all of the notes at certain times by paying a premium as specified in the indenture, plus accrued and unpaid interest.

All of our senior unsecured notes and the related guarantees are effectively subordinated to the Issuers’ and the Guarantor’s existing and future secured indebtedness to the extent of the collateral securing such indebtedness. All of our senior unsecured notes and the related guarantees are also effectively subordinated to all indebtedness and other liabilities of the Issuers’ subsidiaries other than the Guarantor. On March 22, 2017, the Issuers and the Guarantor filed a registration statement on Form S-4 with the SEC which offered to exchange the unregistered New Notes for registered, publicly tradable notes that have substantially identical terms as the New Notes. The registration statement on Form S-4 was declared effective by the SEC on April 27, 2017 and the exchange offer expired on May 24, 2017.
