Answer:
a) 15 March 2018
b) 58 days passed between the last coupon paid and the settlement date
c) There are 123 days in the current coupon period.
Step-by-step explanation:
a) So, next coupon will be paid on 15 March 2018.
(b) Coupon was paid on 15th September 2017 and settleent date is November 12, 2017, hence using the ACT/ACT day count convention, the number of days passed between the last coupon paid and the settlement date is (15 days of September + 31 Days of October + 12 days of November) = 58 days.
(c) The next coupon date is 15th March 2018. Hence, the number of days in current coupon period is (18 days of November + 31 days of December + 31 days of January + 28 days of February + 15 days of March ) = 123 days
