[1] The Partnership pays franchise margin taxes on revenues in Texas related to its investments in unconsolidated entities. Such taxes are paid by the Partnership as the unconsolidated entities are required by tax regulations to be included in the Partnership’s group franchise tax return. Since the Partnership is reimbursed for the franchise margin taxes paid on behalf of the unconsolidated entities, these taxes are not reported on the Partnership’s condensed consolidated statements of operations.
[2] The Partnership has an agreement with an affiliate of Greystone, in which the Greystone affiliate is entitled to receive a referral fee up to 0.25% of the original principal amount of executed tax-exempt loan or tax-exempt bond transactions introduced to the Partnership by the Greystone affiliate. The term of the agreement ends December 31, 2026, unless the parties mutually agree to extend the term. The Partnership accounts for referral fees as bond acquisition costs that are deferred and amortized as a yield adjustment to the related investment asset.
[3] Greystone Servicing, an affiliate of the Partnership, is the servicer for the 2024 PFA Securitization Bonds.
[4] Greystone Select, an affiliate of the Partnership, has provided a guaranty of $8.4 million of the Partnership's mortgage loan secured by the SC MF Properties (Note 14), which in the event of prepayment, will be reduced to 10% of the outstanding principal under the mortgage. GSI’s obligations under the guaranty shall survive a foreclosure, deed-in-lieu of foreclosure or similar proceeding. GSI is required to comply with certain financial reporting and covenants. The Partnership pays a 0.80% per annum fee on the guaranty amount to Greystone Select.
[5] The General Partner is entitled to receive an administrative fee from the Partnership equal to 0.45% per annum of the outstanding principal balance of any of its investment assets for which the owner of the financed property or other third party is not obligated to pay such administrative fee directly to the General Partner. The disclosed amounts represent administrative fees paid or accrued during the periods specified and are reported within “General and administrative expenses” on the Partnership’s condensed consolidated statements of operations.
