Decision and objectives

The terms asset-backed and asset-covered sound similar but can describe materially different legal claims. In a covered security, identify the issuer's general obligation and the dedicated cover assets. In a securitization, identify transferred assets and the vehicle's payment rules. Do not decide solely from the English translation or from an asset list.

Objectives: Identify general issuer and cover-pool claims; Calculate a simplified collateral buffer; Avoid double counting recoveries.

Prerequisites: C2T6L3.

Mechanics

SPK's III-59.1 describes covered securities as debt-type instruments that are a general obligation of the issuer and supported by cover assets. Its framework includes a collateral register and matching provisions. III-58.1 addresses asset-backed or mortgage-backed structures and financing funds. These are separate regulatory frameworks; actual rights, insolvency treatment and enforcement still require the issue documents.

Dual recourse is a useful descriptive phrase when the terms provide a claim to the issuer and the cover assets. It does not mean investors may collect more than their recognized claim by counting the same asset in two recoveries. Registered cover assets can change over time under the applicable substitution rules; initial pool quality is not a permanent observation.

Price and return drivers

A simplified nominal overcollateralization ratio = (eligible cover assets − covered obligations) / covered obligations. This is an educational ratio, not the full regulatory matching test: valuation haircuts, currency, interest, liquidity and derivative claims can matter. Stressed asset value = stated pool value × (1 − assumed haircut), adjusted for any further costs. Adequate nominal coverage can disappear under credit losses or enforcement discounts.

Worked case

Hypothetical restricted TRY covered issue: recognized obligations TRY 100 million; stated eligible pool TRY 120 million; no other priority claims in this simplified example. Nominal buffer = TRY 20 million; overcollateralization = 20/100 = 20%. Apply a 15% stress haircut to the pool: stressed gross value 120×0.85 = TRY 102 million. After hypothetical enforcement expense TRY 5 million, net pool realization is TRY 97 million, leaving TRY 3 million below the claim.

Assume the governing recovery arrangement then provides TRY 2 million from the general issuer estate on the remaining shortfall, without overlap. Total recovery = min(100,97+2) = TRY 99 million; recognized-claim recovery 99%. The issuer obligation adds potential recourse, not certain or unlimited cash.

Adverse case

At zero haircut the same pool after TRY 5 million expense produces TRY 115 million, but holders cannot collect 115 on a recognized claim of 100 under this supplied rule. At 30% haircut, pool net is 120×0.70−5 = TRY 79 million; adding the same fictional estate amount gives TRY 81 million, or 81% recovery. These are final realization scenarios, not current executable prices. Currency or interest mismatches can cause payment-date shortfalls before final enforcement.

Practical use

Read the issue's current register reports, cover eligibility, substitutions, valuation basis, matching tests, monitor duties, default and payment provisions. Check whether any derivatives rank against cover assets. The fictional issue is restricted; actual public offerings and other distribution routes can differ and must be verified by series. MKK lists covered instruments in domestic custody scope. Costs, custody and investor tax remain separate from the pool-coverage arithmetic.

Decision boundaries

A cover pool can improve a claim without making it risk-free. Do not treat nominal asset coverage as an immediate liquidity reserve or generalize a foreign covered-bond legal outcome to Turkey. Decline a comparison that presents securitized limited recourse and issuer-plus-cover recourse as identical without reading either document. Also decline when a required asset report is stale or missing.

Practice and references

Exercise: hypothetical covered obligations TRY 80 million; eligible assets 100 million; stress haircut 20%; realization costs 3 million; no other recovery. Answer: nominal overcollateralization 25%; net stressed pool = 100×0.80−3 = TRY 77 million; shortfall 3 million; recovery 96.25%. No regulatory minimum is being tested.

Takeaway: identify the legal claims, then assess their combined recoveries without counting assets twice.
