Answer:
Calvin would have a long-term capital gain of $1000.
Step-by-step explanation:
Calvin's contributions towards partnership is as below
Beg $43,000
2010 income $22,000
2011 income $25,000
2010 income $12,000
Total contribution $102,000
Total amount Calvin realized by selling his partnership interest = $103,000.
Therefore, Calvin would have a long-term capital gain of $1000 (amount Calvin realized - Calvin's contributions = $103,000 - $102,000).
