On January 1, 2016, Labtech Circuits borrowed $100,000 from First Bank by issuing a three- year, 8% note, payable on December 31, 2018. Labtech wanted to hedge the risk that general interest rates will decline, causing the fair value of its debt to increase. Therefore, Labtech entered into a three-year interest rate swap agreement on January 1, 2016, and designated the swap as a fair value hedge. The agreement called for the company to receive payment based on an 8% fixed interest rate on a notional amount of $100.000 and to pay interest based on a floating interest rate tied to LIBOR. The contract called for cash settlement of the net interest amount on December 31 of each year. Floating (LIBOR) settlement rates were 8% at inception and 9%, 7%, and 7% at the end of 2016, 2017 and 2018, respectively. The fair values of the swap are quotes obtained from a derivatives dealer. These quotes and the fair values of the note are as follows: January 1 December 31 2016 2016 2017 2018 Fair value of interest rate swap 0 $ (1,759) S 935 0 Fair value of note payable $100,000 $98,241 $100,935 $100,000 2.

Prepare the journal entries during 2017 to record interest, net cash interest settlement for the interest rate swap, and necessary adjustments for changes in fair value. 4.
