Pledges must be distinguished by the extent to which they are restricted.

A private college receives the following pledges of support.

1. As part of its annual fund drive, alumni and friends of the college pledge $8 million. The college estimates that about 15 percent of the pledges will prove uncollectible.
2. A CPA firm promises to establish an endowed chair in the accounting department by donating $500,000. The chair agreement will provide that the funds be used to purchase investment grade securities and that the income from the securities be used to supplement the salary of the chair holder and support his or her academic activities.
3. A private foundation promises to donate $100,000 to be used to support a major revision of the college's accounting curriculum.
4. An alumnus pledges $25,000 to the college's loan fund, which is used to make loans to students requiring financial assistance.
5. The college is seeking support for construction of a new athletic fieldhouse. A local real estate investor promises to donate 10 acres of land on which a fieldhouse could be built if the college is able to raise the funds required to construct the building. The land has a market value of $1 million.

Indicate the category of net assets (unrestricted, temporarily restricted, or permanently restricted) in which each of the contributions should be recorded and the amount of revenue, if any, that should be recognized when the pledge was made. Briefly explain your response.
