Final answer:
The clean price of the bond is calculated by subtracting the accrued interest from the invoice price, resulting in a clean price of $1,010.50.
Step-by-step explanation:
To calculate the clean price of the bond, we first need to understand that the invoice price (also known as the dirty price) includes accrued interest, while the clean price does not. The bond has a semiannual coupon rate, which means it pays interest twice a year. At a 6.9% annual coupon rate, each payment is 3.45% of the par value ($1,000), leading to a $34.50 coupon payment every six months.
Since there are four months to the next coupon date, two months of interest have been earned since the last coupon. As a six-month period would earn $34.50, two months would earn approximately $11.50 (34.50 * 2/6).
Therefore, to find the clean price, we subtract the accrued interest from the invoice price: $1,022 - $11.50 = $1,010.50. So, the clean price of the bond is $1,010.50.
