Downside Cases in NPL Pricing

The price at which an NPL portfolio meets the required return under base-case assumptions is one number. The price at which the portfolio avoids a loss under adverse assumptions is another. The distance between those two numbers — and the assumptions that drive the difference — tells you what risk you are actually taking.

Downside-case pricing is not a formality. It is the discipline that distinguishes investment from speculation. In Morocco, where enforcement timelines are long, data quality is variable, and the legal framework for NPL transfers is still developing, understanding the downside is particularly important.

Why base case is not enough

A base-case projection incorporates the most likely assumptions about recovery rates, timelines, costs, and borrower behaviour. It produces a single expected value for the portfolio and, when discounted at the required return, a maximum bid price.

The problem is that "most likely" is not "certain." The base case is a point estimate in a distribution of outcomes. Acquisitions priced tightly to base case will occasionally lose money when outcomes fall in the left tail of that distribution.

The purpose of the downside case is not to predict failure. It is to quantify the exposure to adverse outcomes and to ensure the bid price incorporates an appropriate margin of safety.

Downside is not a haircut

The most common error in downside analysis is applying a uniform percentage reduction to the base case. "Base case says MAD 60 million recovery; downside is 20% lower, so MAD 48 million." This approach is seductively simple and analytically useless.

A uniform haircut tells you nothing about which risks you are exposed to. It does not identify whether the downside comes from collateral values, enforcement timelines, borrower behaviour, or legal uncertainty. It provides no basis for structuring protections, negotiating reps and warranties, or focusing post-acquisition servicing effort.

Constructing a coherent downside

A useful downside case has three characteristics: it is specific, it is internally consistent, and it is plausible.

Specific assumptions

The downside should identify the particular assumptions being stressed. In a typical Moroccan NPL portfolio, the drivers that carry most of the value are:

• Realisation values on the largest secured exposures
• Enforcement timelines through the Moroccan court system
• Recovery rates on unsecured and under-secured exposures
• Costs of enforcement and servicing
• Cure rates on exposures still in amicable collection

Each of these can be stressed individually to understand sensitivity, but the downside case tests them in combination.

Internal consistency

Adverse assumptions should be logically connected. A scenario in which collateral values fall 30% but enforcement timelines remain unchanged is internally inconsistent; distressed market conditions that depress values also typically slow transactions and extend timelines. A scenario in which courts become slower but legal costs remain constant ignores that extended litigation accrues additional fees.

Internal consistency means the downside case describes a coherent state of the world, not a collection of unrelated haircuts.

Plausibility

The downside should be a scenario that could actually occur, not a theoretical worst case. A scenario in which all collateral becomes worthless and all borrowers disappear is not useful; it provides no guidance because it implies the portfolio should never be purchased at any price.

The appropriate severity depends on the context. For a portfolio with a five-year expected recovery horizon, a downside case should consider conditions that might plausibly arise over that period: an economic downturn, a real estate market correction, court system backlogs, or regulatory changes.

Key stress dimensions for Morocco

For Moroccan NPL portfolios, certain stress dimensions recur across transactions.

Collateral valuation stress

Real estate constitutes the primary collateral in most Moroccan NPL portfolios. Base-case valuations typically rely on appraisals that may be dated, optimistic, or based on comparable transactions that predate current market conditions.

The downside case should test what happens if realisation values are 20-30% below appraisal. This is not an arbitrary haircut; it reflects the discount that distressed sales typically realise relative to orderly-market appraisals, plus the risk that appraisals were themselves optimistic.

For portfolios with concentrated collateral exposure — where a small number of properties account for a large share of expected recovery — individual stress scenarios on the largest positions may be more informative than a portfolio-wide discount.

Timeline extension

Enforcement timelines in Morocco are long by international standards. A base case assuming four years from acquisition to collateral realisation is not aggressive; it reflects reported experience. But "four years on average" contains significant variance. Some cases resolve faster; others encounter procedural obstacles that extend timelines to six, eight, or more years.

The downside case should test an extension of one to two years beyond base case. The impact is significant because extended timelines compound costs (servicing fees, legal fees, holding costs) and reduce present value through additional discounting.

Unsecured recovery deterioration

Unsecured exposures — or the unsecured portion of under-secured exposures — depend on borrower assets and willingness to pay. Base-case assumptions for unsecured recovery are necessarily judgemental and often optimistic.

The downside case should test lower unsecured recovery rates. For individual borrowers, this reflects the risk of asset dissipation, employment loss, or migration. For corporate borrowers, it reflects the risk of liquidation with minimal estate, or of prior-ranking creditors absorbing available assets.

Legal and regulatory risk

Morocco's NPL market is subject to legal evolution. Draft Law 02-26, which would create a specific framework for NPL transfers, has been transmitted for adoption but is not yet enacted. The existing FPCT securitisation route under Law 33-06 involves complexity and cost.

The downside case should consider what happens if legal uncertainties resolve unfavourably: if security transfer is challenged, if enforcement procedures become more cumbersome, or if regulatory requirements on acquirers increase costs.

Concentration risk

Most Moroccan NPL portfolios exhibit concentration: a small number of large exposures account for a disproportionate share of expected recovery. The downside case should test what happens if the largest exposures underperform.

This is not double-counting the collateral stress; it is recognising that idiosyncratic risk on concentrated positions cannot be diversified away within the portfolio. A portfolio where the top ten exposures account for 50% of expected recovery is, in effect, a bet on those ten outcomes.

Mechanics of downside pricing

Once the downside scenario is specified, it flows through the same cash-flow model used for the base case.

Stress the gross recoveries

Apply the downside assumptions to the gross recovery estimates: lower collateral realisations, lower unsecured collection rates, lower cure rates on amicable exposures.

Extend the timelines

Shift the cash flows later in time according to the timeline stress. A two-year extension means recoveries projected for year three in the base case arrive in year five in the downside case.

Increase the costs

Adjust costs for the extended timeline and any additional expenses implied by the scenario. Longer enforcement means more servicing months, more legal fees, and potentially additional court costs.

Discount at the required return

Discount the stressed cash flows at the same required return used for the base case. This produces the downside recovery value in present-value terms.

Calculate the downside price

The downside price is the acquisition cost at which the portfolio still earns the required return — or, more conservatively, the cost at which it avoids a loss (i.e., returns at least the investment).

Interpreting the output

The output of downside analysis is not a single number but a comparison.

| Scenario | Max Acquisition Price | |----------|----------------------| | Base case at 15% IRR | MAD 42 million | | Downside at 15% IRR | MAD 31 million | | Downside at 0% (breakeven) | MAD 36 million |

This table tells a story. Paying MAD 42 million earns 15% if the base case materialises but loses money if the downside materialises. Paying MAD 36 million earns more than 15% in the base case and breaks even in the downside. Paying MAD 31 million earns 15% even in the downside.

The appropriate bid depends on the investor's risk tolerance, the degree of confidence in the base-case assumptions, and the competitive dynamics of the transaction. But the table provides the information needed to make that decision consciously rather than accidentally.

Relationship to portfolio pricing

Downside analysis connects directly to bid strategy.

Margin of safety

The difference between the base-case price and the downside price represents the margin of safety available in the portfolio. A wide margin indicates resilience to adverse outcomes; a narrow margin indicates a portfolio that can be derailed by small deviations from expectation.

Negotiating leverage

Understanding which assumptions drive the downside provides negotiating leverage. If the downside is driven by uncertainty on a specific large exposure, the investor can seek reps and warranties, price adjustments, or structural protections specifically addressing that exposure.

Post-acquisition focus

The downside analysis identifies which exposures and which risks carry the most potential for value loss. Post-acquisition servicing and monitoring should prioritise those risks.

Common pitfalls

Several errors recur in downside analysis.

Optimism bias

The downside case should not be "base case minus a little." If the downside feels comfortable, it is probably not severe enough. The test is whether the scenario would actually cause concern if it materialised, not whether it seems likely.

Inconsistent treatment

All scenarios — base and downside — should use the same model structure and cost assumptions (appropriately adjusted). Comparing a detailed base case to a rough downside estimate produces meaningless results.

Ignoring tail risk

The downside case tests one adverse scenario, not all possible adverse scenarios. Truly catastrophic outcomes — economic collapse, expropriation, complete legal framework failure — may warrant separate consideration, even if they are not incorporated in the primary downside case.
