Decision and objectives

Choose whether the method addresses this lesson’s task before placing an order. Objectives: 1. Reconstruct three different certificate payoffs. 2. Identify a conditional bonus versus unconditional repayment. 3. Calculate capped gains and barrier-related loss.

Prerequisite: C4T8L2.

All prices, ratios, term sheets, credit recoveries and cash dates below are hypothetical teaching assumptions, not current offers. Amounts are TRY unless explicitly marked otherwise. The investor is a hypothetical Turkey-resident individual acting outside a business; all results are before actual tax, which requires issue, acquisition, income-year and legal-status checks. No current eligibility or live listing is asserted.

Mechanics

A discount certificate offers entry below the reference value in exchange for capped participation. A bonus certificate can promise a specified conditional payment if a barrier is not breached; once breached, a different formula applies. A capped participation product limits gains even when the reference continues rising. These are issuer promises with issue-specific rights, not generic guarantees. Names must be translated into signed cash formulas and a path record. A discount is not principal protection.

Price and return drivers

For the declared simple discount unit, cash=min(S,cap). A conditional bonus unit pays max(S,bonus) if the barrier survives; after a touch it paysS. The stated capped participation unit pays principal ×[1 +min(participation ×positive reference return,cap return)] for gains, with full reference downside for negative returns. These are original synthetic formulas, not universal definitions. Ratios, FX, observation time, caps, issuer performance and tax treatment must be supplied before applying any real term sheet.

Worked case

Compare separate synthetic100-unit issues, European final observation and TRY cash payment two business days later; all obligations are unsecured issuer claims. Discount: price90,cap105,fees20 for100 units. Bonus: price100,bonus110,lower touch barrier70 monitored through expiry,fees20. Capped participation:10000 principal,150% positive participation capped at20% total gain,full downside,fees20 paid separately. Initial reference100. At finalS60,100,140: discount net−3020,+980,+1480. Bonus with barrier touched forS60 but untouched for100 and140 gives−4020,+980,+3980. Capped participation gives−4020,−20,+1980. The100 and140 bonus paths are explicitly assumed unbreached; their final levels alone would not establish that fact.

Adverse case

A bonus path touching70 then ending100 pays100 per unit, giving−20 rather than the unbreached980. That1000 difference is the cost of the lost condition. A discount atS0 can lose the entire9020 paid including fees. Before expiry supplied exit bids88 for discount and95 for bonus produce−220 and−520 respectively; conditional maturity promises do not set guaranteed interim bids. All three remain subject to issuer default; the full contractual formula can overstate received cash if the obligor fails.

Practical use

Read the cap and bonus path condition with the issue ratio and cash calendar. Distinguish a discretionary provider repurchase from a guaranteed redemption right.

For any actual domestic implementation, verify the exact issue/contract, authorized intermediary, account permission and executable size. Include spread, commissions, passed-through fees, funding/borrow, custody and exercise/exit costs without double-counting embedded charges. Recheck income year, residency/status, issue/acquisition dates and effective tax law; all case results remain before actual tax.

Decision boundaries

Use the structure only when the capped or conditional outcome fits the objective and the path conditions are verifiable. Decline a “bonus” offer if the investor interprets the bonus as unconditional interest. Compare direct ownership including distributions, which these synthetic formulas omit. A high participation rate is incomplete without the cap and downside formula. A certificate sold below initial reference can still impose substantial loss and give up upside.

Practice and references

Exercise:100 discount units at80,cap95,total fees30. Solution: AtS90 cash9000 and net970; atS120 cash9500 and maximum net gain1470; atS50 cash5000 and loss3030. Expiry breakeven80.30 provided it lies below the cap. A pre-expiry bid is still required for an earlier cash need.

Takeaway: Discounts, bonuses and participation caps exchange rights and risks; reconstruct each formula and barrier condition. Reference links: product card, formula; glossary: Discount certificate; Bonus certificate; Participation cap. Next: C4T8L4. Topic test.
