MSG Corporation has $1,000,000 of 10-year, 6% bonds outstanding on December 31, 2020. The bonds have 3 years remaining to maturity. Assume interest is paid at the end of each month. The unamortized premium remaining on these bonds was $60,000. MSG uses straight-line amortization, so the unamortized premium would be $40,000 on December 31, 2021, provided none of the bonds had been retired before that day. On May 1, 2021, $100,000 of the bonds were retired at 112. How much, and what type of gain or loss, results from the retirement?
