Answer:
For 2015, the number of days of accrued interest will be:
330 days.
Step-by-step explanation:
The accrued interest on the municipal bonds purchased with 9% nominal yield for settlement on February 1, 2015 will be 330 days (360 - 30), based on 360 days for a year. The use of 360 days is based on day-count convention for municipal bonds while 30 days is used as the average for each month and 12 * 30 = 360 days. For example, if the bonds are worth $100,000, then the accrued interest will be equal to $8,250. This is calculated as ($100,000 * 9% * 330/360).
