The document contains three exercises describing bond issuances with different interest payment schedules. The first exercise describes a $400,000 bond issuance with 8% interest payable semiannually. The second describes a $500,000 bond issuance with 6% interest also payable semiannually. The third describes another $500,000 bond issuance but with 6% interest payable annually. Each exercise asks to record the bond issuance at face value and the first one or two interest payments depending on the schedule.
