consideration consisted almost entirely of notes due in 2027 issued by the buyer of the timberland, which Temple-Inland contributed to two wholly-owned, bankruptcy-remote special purpose entities. The notes are shown in Long-term financial assets of variable interest entities in the accompanying consolidated balance sheet and are supported by $2.4 billion of irrevocable letters of credit issued by three banks, which are required to maintain minimum credit ratings on their long-term debt.

In December 2007, Temple-Inland's two wholly-owned special purpose entities borrowed $2.1 billion which is shown in Long-term nonrecourse financial liabilities of variable interest entities. The loans are repayable in 2027 and are secured by the $2.4 billion of notes and the irrevocable letters of credit securing the notes, and are nonrecourse to us. The loan agreements provide that if a credit rating of any of the banks issuing the letters of credit is downgraded below the specified threshold, the letters of credit issued by that bank must be replaced within 30 days with letters of credit from another qualifying financial institution.

As of both December 31, 2023 and 2022, the fair value of the notes receivable was $2.3 billion. As of both December 31, 2023 and 2022, the fair value of this debt was $2.1 billion. The notes receivable and debt are classified as Level 2 within the fair value hierarchy.

In connection with the 2006 sale of approximately 5.6 million acres of forestlands, International Paper received installment notes (the "Timber Notes") totaling approximately $4.8 billion. The Timber Notes were used as collateral for borrowings from third party lenders, which effectively monetized the Timber Notes through the creation of newly formed special purposes entities (the "Entities"). The monetization structure preserved the tax deferral that resulted from the 2006 forestlands sales. During 2015, International Paper initiated a series of actions to extend the 2006 monetization structure and maintain the long-term nature of the deferred tax liability. The Entities, with assets and liabilities primarily consisting of the Timber Notes and third-party bank loans (the "Extension Loans"), were restructured which resulted in the formation of wholly-owned, bankruptcy-remote special purpose entities (the "2015 Financing Entities").

In August 2021, the Timber Notes of $4.8 billion and the Extension Loans of $4.2 billion related to the 2015 Financing Entities both matured. We settled the Extension Loans at their maturity with the proceeds from the Timber Notes. This resulted in cash proceeds of approximately $630 million representing our equity in the variable interest entities. Maturity of the installment notes and termination of the monetization structure also resulted in a $72 million tax liability that was paid in the fourth quarter of 2021.

On September 2, 2022, the Company and the Internal Revenue Service agreed to settle the previously disclosed timber monetization restructuring tax matter involving the 2015 Financing Entities. Under this agreement, the Company was required to fully resolve the matter and pay $252 million in U.S. federal income taxes. As a result, interest was charged upon closing of the audit. The amount of interest expense recognized in 2022 was $58 million. As of December 31, 2023, $252 million in U.S. federal income taxes and $58 million in interest expense have been paid as a result of the settlement agreement. The Company paid $163 million in U.S. federal income taxes and $30 million in interest during the first quarter of 2023 and fully satisfied the payment terms of the settlement agreement regarding the 2015 Financing Entities timber monetization restructuring tax matter during the second quarter of 2023. The reversal of the Company’s remaining deferred tax liability associated with the 2015 Financing Entities of $604 million was recognized as a one-time tax benefit in the third quarter of 2022.
