The proceeds from the issuance have been loaned to IFCo, together with a contribution by OCI, to refinance the Iowa Finance Authority Midwestern Disaster Area Revenue Bonds (Iowa Fertilizer Company Project), Series 2013 and Series 2018A and B, as well as to pay fees and costs related to the issuance of the Series 2022 Bonds.

The Series 2022 Bonds have been issued pursuant to an Indenture by and between the Iowa Finance Authority and the Trustee. Interest on the Series 2022 Bonds is exempt from U.S. federal income tax and is non-AMT.
