Detailed Answer
(c) Unrestricted net assets increased $250,000 for the
year ended December 31, 2012. The $50,000 spent on research
during 2012 would be reclassified (added) to unrestricted net
assets when the money was spent for research. The $50,000
addition to unrestricted revenues, gains, and other support would
be accompanied by a $50,000 reclassification (deduction) from
temporarily restricted revenues. The expenses of $50,000 for
research are deducted from unrestricted revenues, etc., which
include the $50,000 reclassification. Therefore, the net effect on
unrestricted net assets of spending $50,000 on research is zero.
The $250,000 of gift shop revenue is unrestricted revenue because
the governing board has control of this revenue.
