In April 2021, the Issuers issued $455 million in aggregate principal amount of additional 5.250% senior unsecured notes due 2027. The proceeds from this issuance were used to redeem the remaining $455 million principal amount of 6.250% senior unsecured notes due 2022, and to pay accrued interest, related fees and expenses.
Each of our senior unsecured notes and the related guarantees are the senior unsecured obligations of the Issuers and rank equally with all of the Issuers’ and the Guarantor’s existing and future senior unsecured indebtedness and senior to all of the Issuers’ and the Guarantor’s existing and future subordinated indebtedness. Each 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. Each 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.
The indentures governing our senior unsecured notes described above restrict the payment of cash distributions, the purchase of equity interests or the purchase, redemption, defeasance or acquisition of debt subordinated to the senior unsecured notes. The indentures also restrict the incurrence of debt or the issuance of disqualified stock, as defined in the indentures, with certain exceptions. In addition, the indentures require that on each quarterly determination date, Icahn Enterprises and the guarantor of the notes (currently only Icahn Enterprises Holdings) maintain certain minimum financial ratios, as defined therein. The indentures also restrict the creation of liens, mergers, consolidations and sales of substantially all of our assets, and transactions with affiliates. Additionally, each of the senior unsecured notes outstanding as of June 30, 2021, except for the 4.750% senior unsecured notes due 2024, the 5.250% senior unsecured notes due 2027 and 4.375% senior unsecured notes due 2029, are subject to optional redemption premiums in the event we redeem any of the notes prior to certain dates as described in the indentures.
As of June 30, 2021 and December 31, 2020, we were in compliance with all covenants, including maintaining certain minimum financial ratios, as defined in the indentures. Additionally, as of June 30, 2021, based on covenants in the indentures governing our senior unsecured notes, we are not permitted to incur additional indebtedness; however, we are permitted to issue new notes in connection with debt refinancings of existing notes.
