The same $2,000,000 face amount and 6 percent coupon can sell below, at, or above face. The supplied market yield explains which. Cedar Trail's market yield is 8 percent annually, or 4 percent for each of eight semiannual periods.

Price the streams separately:

coupon stream = $60,000 × ordinary-annuity factor(4%, 8)
principal stream = $2,000,000 × single-sum factor(4%, 8)
issue price = coupon present value + principal present value

With full precision, the price is $1,865,345.10. Face exceeds price by $134,654.90, so the bond is issued at a discount. Nothing was “lost” at issuance. Investors paid the present value of the promised cash flows at the supplied yield.

The two-rate test

Coupon cash uses face amount and 3 percent per period: $60,000. Effective interest later uses opening carrying amount and 4 percent. If a schedule uses 4 percent to calculate cash or 3 percent to calculate expense, the columns have changed roles.

If the supplied market yield were 5 percent annually while the coupon remained 6 percent, price would exceed face and the bond would carry a premium. The direction reverses; the method does not.

Exit check

Write the principal and coupon present-value equations with labels, not only function calls. Explain why issue price is neither face amount nor the sum of all undiscounted future cash. Recompute with a one-point yield change and describe the direction before looking at the number.
