        <ExplanationTxt>The Organization is exempt from income taxes under Section 501(c)(3) of the Internal Revenue Code and applicable state law, except for taxes pertaining to unrelated business income, if any. The accounting standard on uncertainty in income taxes addresses the determination of whether tax benefits claimed or expected to be claimed on a tax return should be recorded in the financial statements. Under this guidance, the Organization may recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by taxing authorities, based on the technical merits of the position. Examples of tax positions include the tax-exempt status of the Organization, the continued tax-exempt status of bonds issued by the Organization, and various positions related to the potential sources of unrelated business taxable income. The tax benefits recognized in the financial statements from such a position are measured based on the largest benefit that has a greater than 50 percent likelihood of being realized upon ultimate settlement. There were no unrecognized tax benefits identified or recorded as liabilities during the periods covered by these financial statements. The Organization files Forms 990 in the U.S. federal jurisdiction and the state of Illinois. Forms 990 filed by the Organization are subject to examination by the Internal Revenue Service (IRS) up to three years from extended due to date of each return. The Organization is generally no longer subject to examination by the IRS for years before 2020.</ExplanationTxt>

Annually each director provides a "Conflict of Interest" statement certifying that he/she is not engaged in any activities that would constitute a conflict of interest. For our part, the Corporate Compliance officer monitors the companies with which each of our directors is employed and/or owns to determine if those companies have procured or are seeking to procure business with Gateway Foundation, Inc., or with the business of any other director. Per our conflict of interest policy, if it is determined that a conflict exists, the Supply Management Director or designee will investigate alternatives to the proposed vendor.</ExplanationTxt>
