Choice "B" is correct. Good faith deposits associated with conditional promises would be recorded as a liability titled "refundable advance." The use of the $1,000,000 gift is conditional upon raising matching funds from others. Until the matching funds are received (or the condition has been substantially met), the monies contributed are payable back to the donor. No revenue is recognized.
Choice "d" is incorrect. Although the ultimate purpose of the gift provided to Gridiron University will be temporarily restricted, it is currently conditional and therefore would not be recognized as revenue. It is a refundable advance until the condition is met.
Choice "a" is incorrect. The gift provided to Gridiron University is conditional and therefore would not be recognized as revenue. It is a refundable advance until the condition is met.
Choice "c" is incorrect. Although a material conditional gift would likely be disclosed, it would also be reported as a refundable advance, a liability on the face of the financial statements.
