Financial Statement Notes

PART X, LINE 2:

“Income taxes: castle square tenant organization (the organization) is a nonprofit organization as described in section 501(3) of the internal revenue code and is exempt from federal and state income taxes on trade or business profits generated by activities related to the organization's exempt function. The organization may be subject to federal and state income taxes for profits generated from trade or business activities unrelated to the organization's exempt function. As of december 31, 2024, management believes that the organization has not generated any unrelated business taxable income. The organization assesses the recording of uncertain tax positions by evaluating the minimum recognition threshold and measurement requirements a tax position must meet before being recognized as a benefit in the consolidated financial statements. The organization's policy is to recognize interest and penalties accrued on any uncertain tax positions as a component of income tax expense, if any, in its consolidated statement of activities. The organization has not recognized any liabilities for uncertain tax positions or unrecognized benefits as of december 31, 2024. The organization does not expect any material change in uncertain tax benefits within the next 12 months.”
