[1] 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, 2023, unless the parties mutually agree to extend the term. The Partnership accounts for referral fees as bond origination costs that are deferred and amortized as a yield adjustment to the related investment asset.
