(iv) Grantors and contributors. Prior to the making of any grant or contribution that will allegedly meet the requirements for exclusion under paragraph (f)(6)(ii) of this section, a potential grantee organization may request a determination whether such grant or contribution may be so excluded. Requests for such determination may be filed by the grantee organization in the time and manner specified by revenue procedure or other guidance published in the Internal Revenue Bulletin. The issuance of such determination will be at the sole discretion of the Commissioner. The organization must submit all information necessary to make a determination on the factors referred to in paragraph (f)(6)(iii) of this section. If a favorable determination is issued, such determination may be relied upon by the grantor or contributor of the particular contribution in question for purposes of sections 170, 507, 545(b)(2), 642(c), 4942, 4945, 4966, 2055, 2106(a)(2), and 2522 and by the grantee organization for purposes of paragraph (f)(6)(ii) of this section.
