Darcy borrowed $4,000 in 2014 from her employer to purchase a new computer. She repays $1,000 of the loan plus 6% interest on the unpaid balance in 2014, 2015, and 2016. After closing a big deal in 2017, she receives the original loan agreement stamped ``paid in full'' across the face. Does Darcy have to recognize any income from the cancellation of the loan in 2017? Explain.
