You are considering purchasing a coupon bond with a face value of $1,000,000 in the secondary market that has 4 years and 3 months to maturity. Assuming the coupons are paid quarterly, and the bond is currently trading for $1,058,627.35, with a yield of 6.8% p.a., calculate the coupon rate for the bond. (Assume that the per annum yield and per annum coupon rate are quoted consistent to the bond quotation conventions discussed in the course.)
