| IRS990ScheduleA/FactsAndCircumstancesTestTxt | 0 | Prior Year Facts and Circumstances: As a nonprofit organization, Letterform Archive must be able to demonstrate that it "normally" receives at least 33 1/3% of its support from the general public. In calculating this support test, Form 990 Schedule A reflects a support percentage of a little more than 21% for the year ended December 31, 2019. Letterform Archive believes that other factors provide sufficient evidence that the organization is a valid publicly supported nonprofit charity. The other test is a facts and circumstances test. Under this test, the organization is treated as publicly supported if it normally receives a substantial part of its support from governmental units, from direct or indirect contributions from the general public, and if it is organized and operated to attract new and additional public or governmental support on a continuous basis [Reg. Section 1.170A-9(e)(3)]. The organization will be treated as normally receiving substantial public support if at least 10 percent of the total support normally received by the organization is governmental or public support [Reg. Section 1.170A-9(e)(3)(i)]. An organization meets the requirement of attracting new and additional public or governmental support if it maintains a continuous and bona fide program for soliciting funds from the general public or it carries on activities designed to attract support from governmental units, churches, educational organizations, or other publicly supported charitable or cultural organizations [Reg. Section 1.170A-9(e)(3)(ii)].Letterform Archive has an active ongoing campaign to secure funds from a variety of third-party sources. Various staff members work diligently to solicit funds from foundations and corporate entities. Prior contributors are added to the organization's donor database and follow up contact is made through a combination of mailings and e-mails. Letterform Archive has a diverse Board of Directors, with representatives from a variety of backgrounds providing guidance, support and foresight.For these reasons, Letterform Archive has demonstrated that it satisfies Internal Revenue Service regulations to be classified as a publicly supported exempt organization. |
