# Evaluating Sustainability Linked Loans

Structures SLL analysis with KPI assessment, margin ratchet evaluation, and ambition verification against the Sustainability Linked Loan Principles (SLLP).

## When To Use

- Evaluating a proposed or existing sustainability-linked loan facility
- Assessing whether SLL KPIs are material, ambitious, and measurable
- Reviewing margin ratchet structures for economic alignment with sustainability targets
- Comparing an SLL against SLLP or LSTA/LMA guidance
- Conducting due diligence on greenwashing risk in an SLL structure

## Inputs To Gather

- **Loan documentation**: Credit agreement, SLL rider or sustainability amendment, term sheet
- **KPI definitions**: Exact metric definitions, calculation methodology, baseline values, and target trajectories
- **Sustainability Performance Targets (SPTs)**: Target levels per KPI, measurement dates, calibration basis
- **Margin ratchet schedule**: Basis point adjustments (discount and premium) tied to each SPT
- **Borrower disclosures**: Sustainability reports, CDP submissions, science-based targets (SBTi) commitments, ESG ratings
- **External verification**: Second-party opinion (SPO), annual verification reports, auditor assurance letters
- **Sector benchmarks**: Industry-average performance on selected KPIs, peer SLL structures [VERIFY sector-specific benchmarks against current data sources]

## Workflow

1. **Map KPIs to materiality**
   - Confirm each KPI is core to the borrower's business and ESG risk profile
   - Cross-reference against SASB materiality map or sector-specific standards
   - Flag KPIs that are immaterial, easily gamed, or duplicative

2. **Assess KPI quality**
   - Verify each KPI has a clear, auditable calculation methodology
   - Check for consistent baseline year and scope boundaries (e.g., Scope 1+2 vs. Scope 1+2+3 for GHG metrics)
   - Confirm data sourcing — internal reporting vs. third-party verified
   - Evaluate whether the KPI is within borrower operational control

3. **Evaluate SPT ambition**
   - Compare targets against: borrower historical trajectory, sector peers, science-based pathways (e.g., SBTi 1.5C for emissions)
   - Determine if targets represent genuine stretch beyond business-as-usual
   - Check target timeline — multi-year ramps are preferred over single-year snapshots
   - Note if targets reset, step up, or remain static over the loan tenor
   - [VERIFY] Whether the borrower's SBTi commitment is validated or merely pledged

4. **Analyze margin ratchet mechanics**
   - Map the ratchet schedule: basis points per KPI, symmetry of reward/penalty, and cap/floor
   - Assess economic materiality — ratchet of <5 bps on a large facility may be tokenistic
   - Check whether ratchet is two-way (discount for meeting, premium for missing) or one-way
   - Evaluate interaction between multiple KPIs — are ratchets independent or averaged?
   - Identify any "sunset" provisions that reduce or eliminate ratchet obligations over time

5. **Review reporting and verification framework**
   - Confirm annual reporting cadence with defined delivery deadlines
   - Check whether external verification is required (not just encouraged)
   - Identify the verifier's independence and credentials
   - Assess consequences of late or non-delivery of sustainability reports
   - Determine whether an SPO was obtained at structuring and from which provider

6. **Assess structural integrity and greenwashing risk**
   - Flag any provisions allowing KPI substitution or SPT recalibration without lender consent
   - Check for material adverse change (MAC) or force majeure carve-outs that suspend SPTs
   - Evaluate whether proceeds use is unrestricted (SLLs are general-purpose, but note if borrower operates in high-controversy sectors)
   - Compare structure against SLLP five core components: KPI selection, SPT calibration, loan characteristics, reporting, verification

## Output

Produce an **SLL Evaluation Report** containing:

- **Executive summary**: Overall assessment of SLL credibility (strong / adequate / weak) with 2-3 sentence rationale
- **KPI materiality matrix**: Table listing each KPI, its materiality rating, data quality score, and notes
- **SPT ambition assessment**: Per-KPI comparison against baseline, BAU trajectory, peer median, and science-based benchmark
- **Margin ratchet analysis**: Schedule summary, economic materiality assessment, symmetry evaluation
- **Reporting & verification review**: Gaps or strengths in the monitoring framework
- **Risk flags**: Numbered list of greenwashing risks, structural weaknesses, or documentation gaps
- **Recommendations**: Specific actions to strengthen the SLL structure (e.g., add two-way ratchet, require third-party verification, tighten KPI definitions)

## Quality Checks

- Every KPI is assessed against at least one external benchmark or science-based pathway
- Margin ratchet economic impact is quantified in basis points and estimated dollar terms where facility size is known
- All SPTs are evaluated for ambition — not merely whether they exist
- Report flags any KPI lacking third-party verification as a risk item
- [VERIFY] Alignment conclusions reference the current edition of SLLP (LMA/LSTA/APLMA) and applicable regional guidance
- No KPI is rated "strong" without evidence of external benchmarking or science-alignment
- Report clearly distinguishes between verified data and borrower self-reported figures
