A new employee of the City of Kashime was working with the accounting records of several of its funds. This employee, John Fergie, found that a gift had been given to the city for the library. The gift mandated that only the earnings from the gift could be used for library operations. John wanted to set up a Permanent Fund for the principal of the donation to the library and use a Special Revenue Fund to account for the earnings of the investment and their use. Another employee argued that a Private Purpose Trust Fund should be used for both principal and income. Do you agree with either of these individuals, or do you have a better suggestion?
