Streamland SA started producing a new mini series featuring super heroes with useless powers. The management board considered various financing options. The CFO, Sam Yang, suggested to issue convertible bonds, an instrument that had not been used by the company before. The other board members were hesitant at first but eventually agreed that convertible bonds were the best option to finance this production. Therefore, Streamland SA issued 18,000,000 of 8%, 5-year convertible bonds on January 1, 2020, at 95 with interest payable on December 31. Each of the 18,000 1,000 bonds is convertible into 10 ordinary shares (par value of 1). Using the prevailing market interest rates at the issuance date for similar non-convertible bonds, the bonds would have been sold at 90. Any bond premium or discount is amortized annually using the effective-interest method.

At maturity, the bond has been repurchased. Prepare the schedule of bond amortization for the convertible bonds for all years (2020 to 2024) and the journal entry(ies) for the last year of the bond schedule. (15p)
