In 2013, Oregon lawmakers passed a bill that would study pay it forward as a college funding system. The model would allow students to study at university without study and then pay a portion of their income after graduation to finance the cost of their studies. However, unlike the Income Participation Agreement model, Pay It Forward would be publicly funded and would provide fixed percentage repayments for all institutions.  From now on, there are no documented cases of discrimination on the basis of race or sex with ISA agreements, but some fear that the potential for discrimination will increase if ISA becomes a more popular model.  Although anti-discrimination laws in most financial markets would likely apply to ISA investors, the issue has not yet been fully resolved. Some proponents argue that ISAs are less discriminatory than loans: in the UK, this type of agreement has obtained final approval from the UK Financial Regulator (ACF) within a single legal framework. So far, StepEx is the only company to be a regulated ISA provider and to use funds from major UK financial institutions. ISAs are currently only available in the UK for postgraduate degrees in the professional fields of major universities. It is a broader and more affordable alternative to debt for the financing of post-graduate students.  The United States authorizes the income-sharing agreements of its citizens. The public debate on the Oregon plan has sparked renewed interest in equity-based funding models, including a major summit on The New America Foundation`s revenue engagement agreements and a strategy paper from the American Enterprise Institute. On April 9, 2014, Senator Marco Rubio announced the introduction of legislation in the U.S. Congress that would “expand” the use of income participation agreements.
  [It needs to be updated] [With an ordinary student loan], my nominal monthly payment is set, but my income could change or disappear completely (which is just the monthly repetition of bad news). In the case of an income-involved contract, it is the opposite: I do not know what my monthly nominal payment will be over the lifetime, nor the total amount I will pay, but I know I can always afford it.  A participation contract (or ISA) is a financial structure in which a person or organization provides a recipient with something valuable (often a fixed amount of money) who, in return, agrees to repay a percentage of his or her income for a certain number of years. Income participation agreements are characterized by a percentage of future income for a given period of time. They can function as non-voting shares in a company where the individual student is treated as a business. In the U.S. system, this usually involves the investor transferring funds to an individual in exchange for a fixed percentage of their future income.   Other features of income participation agreements may: (a) a fixed period for income participation (b) an income exemption if the borrower is not liable for a specified income and/or c) a redemption option in which the borrower may pay a certain fee for the exit of the contract before the full term.
Some ISA investors offer different students different terms based on their likelihood of success, while others offer the same conditions to all students.
