Hook
After a later expansion, the bicycle shop (illustrative) issued $100,000 of 5-year, 6 percent bonds that pay $3,000 of cash interest every half-year. Sold for $96,000, they cost the shop $34,000 of interest over 10 periods; sold for $104,000, they cost $26,000. This week you met bond terms, present value, bonds issued at face, at a discount, and at a premium, straight-line amortization, the effective-interest method, and debt on the balance sheet.
Your discussion question — choose Option A or Option B; they carry the same weight and the same rubric, and you say which you picked.
Option A: On the day the shop sells its bonds, investors require more than 6 percent, so the bonds sell for $96,000. One founder says the shop "lost $4,000 on the sale." The other says the shop "borrowed $96,000 at a higher cost than 6 percent." Which description gives a lender reading the shop's statements the fairer picture, and why? Use the discount, interest expense, and carrying value in your answer.
Option B: GAAP calls for the effective-interest method, and straight-line amortization is acceptable when its results are not materially different. If you kept the shop's books, how would you decide whether straight-line's even $400 a period is near enough for the shop's $4,000 discount, and who reading the statements might care about the difference? Use straight-line amortization, the effective-interest method, and carrying value in your answer.
There is no single right answer. The arithmetic is not in question here: the cash interest is $3,000 a period in every case, and the discount case's interest expense is $3,400 a period. What is open is how the cost of borrowing is best described and how exact its reporting needs to be.
Expectations
Activity format: one initial post followed by two substantive peer replies. Plan on about 45 minutes across the two deadlines; your instructor sets both due dates in Canvas.
Working on your own: this version of the discussion is written entirely from your own reasoning, in your own words.
Your initial post — by the first due date (early in the module week):
- Say which option you chose.
- For Option A, say which founder's description gives a lender the fairer picture and how the $4,000 reaches the books, using the discount, interest expense, and carrying value; for Option B, say how you would decide whether straight-line's even $400 a period is near enough and who would care about the difference, using both amortization methods and carrying value.
- Keep the arithmetic plain: cash interest is $3,000 a period in every case, and the discount case's interest expense is $3,400 a period. If you write about a real organization you know, describe its borrowing in general terms and state no figures from it.
- Give your judgment, with a reason.
- Length: roughly 150–250 words if written. You may instead record your post as audio or video (about two minutes) and attach a transcript; both forms are scored by the same rubric.
Your replies — by the second due date (the end of the module week):
- Reply substantively to at least two classmates.
- A substantive reply does more than agree: offer the strongest case for the other view, point out a term or figure a classmate misstated, or name a figure from the shop's bonds that would test their claim. "Nice point!" on its own does not count.
What a strong post looks like:
I chose Option A, and the second founder's description is the fairer one. The shop did receive $4,000 less than face, but it did not lose anything that day: it owes $100,000 and holds $96,000 of cash, so the bonds are carried at $96,000. The gap shows up as $400 of extra interest expense in each of the 10 periods, $3,400 a period instead of $3,000. A lender reading "loss" would think something went wrong at the sale, when the real story is that borrowing cost more than 6 percent.
Notice how it names the figures, uses carrying value and interest expense by name, and says what a reader would misunderstand. That is the bar.
Participation rubric
This discussion is worth 10 points. The three criteria below look at your initial post and your peer replies.
| Criterion | Full credit | Partial credit | No credit |
|---|---|---|---|
| Quality of the initial post (4 pts) | A clear position on Option A or B, supported by the shop's bond figures stated accurately, such as the $4,000 discount, the $3,400 of interest expense, or the $96,400 carrying value | A position is present, but the support is general, or a figure is misstated | Missing, off-topic, or no position taken |
| Use of course concepts (3 pts) | Uses discount, interest expense, carrying value, straight-line amortization, or the effective-interest method precisely, and treats the discount as a cost of borrowing rather than a gain or a loss | Uses a term loosely, or treats the discount as a loss on the day of issue | No course terms, or used incorrectly |
| Engagement with peers (3 pts) | Two or more substantive replies that extend or challenge a classmate's reasoning | One substantive reply, or replies that only agree | No replies, or "I agree" with nothing added |
Post early if you can — the best threads happen when people have time to reply before the second due date.
