Answer:
$5,710,000, unamortized bond discount.
Step-by-step explanation:
We will have to approximate the unamortized bond discount on December 31, Year 4
Cash interest payment = $1,000,000 * 9 percent = $90,000
Interest expense charge = $939,000 * 10 percent = $93,900
Amortized discount will be = $93,900 - $90,000 = $3,900
By the end of December 31, Year 4 Unamortized bond discount will be = ($1,000,000 - $939,000) - $3,900 = $5,710,000
