1. Suppose that the foundation were to make a statement of financial position in columnar form, one column for unrestricted net assets, another for temporarily restricted net assets, and a third for permanently restricted net assets. In which column would these receivables be reported? Explain.

2. Suppose that on December 31, 2020, the foundation collected $ 500,000 of the $1, 098,384 due over a five-year period. Make the appropriate journal entries to record the collection of the $500,000 and to adjust the remaining balance in the receivables account. Be sure to recognize interest on the balance of the contributions due in over five years and one to five years (less the discount).

3. Another note to the statements indicates that the foundation has made grants to various other organizations.

Some of these are payable over a five-year period. Accordingly it adjusted its grants payable account to take into account the time value of money and applied adiscount rateof 3 percent. However per the note, the grants are classified as Level 3 in accordance with the fair value hierarchy and have been valued using an income approach. What are the different valuation techniques? What is level 3 classification? Explain this in simple words.
