Answer:
In accrual basis accounting, expenses are recorded in the period when their matching revenues are obtained.
In this case, even if the full interest will be paid at maturity, interest expense will still be recorded in each period according to the information that we are given in the question.
Interest expense to be recorded by December 31
5,200,000 * 0.12 = 624,000 / 2 = 312,000
Interest expense to be recorded by September 30
5,200,000 * 0.10 = 520,000 * 3/12 = 130,000
Interest expense to be recorded by October 31
5,200,000 * 0.09 = 468,000 * 4/12 = 156,000
Interest expense to be recorded by January 31
5,200,000 * 0.06 = 312,000 * 7/12 = 182,000
