"Net donation." In the case of a donation of money, property or identical goods and services made by a secondary donor, the difference between the value of the donation made by the secondary donor and the value of the donation made by the primary donor, provided such value is positive.
"Primary donor." An institution which makes a donation of any money, property, goods or services to an institution of purely public charity.
"Secondary donor." An institution which receives a donation of any money, property, goods or services from a primary donor and then makes a donation back to that primary donor within three years of having received such donation.
"Legitimate subjects of charity." Those individuals who are unable to provide themselves with what the institution provides for them.
"Substantial and indefinite class of persons." Persons not predetermined in number, provided that, where the goods or services are received primarily by members of the institution, membership cannot be predetermined in number and cannot be arbitrarily denied by a vote of the existing members. This subsection specifically recognizes that the use of admissions criteria and enrollment limitations by educational institutions does not constitute predetermined membership or arbitrary restrictions on membership so as to violate this section and recognizes that an institution may reasonably deny membership based on the types of services it provides, as long as denial is not in violation of Federal or State antidiscrimination laws, such as the Civil Rights Act of 1964 ( Public Law 88-352, 78 Stat. 241) and the act of October 27, 1955 (P.L. 744, No. 222), known as the Pennsylvania Human Relations Act.
